The mechanical unit 330 is controlled by the control unit 301 for the production of a prescribed type of fabric.
    The control unit 301 detects an abnormality in the mechanical unit 330 and stops the weaving machine 300.
    Although the textile machine system 1 is illustrated in figures Ì and 2 in which said several weaving machines 300 which are arranged in the textile factory or in a specific area in the textile factory are provided, the textile machine system 1 need only include at least two weaving machines 300. [Information managed by the host computer 200] The host computer 200 maintains and manages the information shown below, for each of the weaving machines 300 A "unit number" is assigned to each of the weaving machines 300, by which each of the weaving machines 300 can be identified.
    A "state" indicates the operational state of each of the weaving machines 300 and the four states indicated below, more specifically: "Operation", "Stop", "Repair completed", "Repair supported" are entered. . The term "operating" means that a weaving machine 300 is in operation. The term "stop" means that a weaving machine 300 is stopped. The term "repair complete" means that the repair of a morning weaving 300 is complete and the weaving machine 300 is awaiting restart. The term "paid repair" means information that relates to a person or machine who takes charge of or who will pay for the repair of a weaving machine 300 that is to be repaired. The expression "repair supported" means either the name of a textile worker who is a worker in charge of repair, or the name of a machine which has an automatic repair function.
    It should be pointed out that the host computer 200 manages information which relates to the type of product in addition to the information which relates to the unit numbers of the weaving machines 300 and the states of the weaving machines 300.
    In the information given above, with respect to the information which refers to the unit number, the host computer 200 uses the information which has been entered in advance. The information regarding the status and the supported repair is updated periodically or at each occurrence of any event that concerns a weaving machine 300. {Processing of information by the host computer 200] Ci- Following will be described processes which are implemented by the host computer 200 in response to information transmitted from the weaving machines 300.
    The textile worker who repairs the weaving machines 300 sends the following information to the host computer 200 via the weaving machines 300 or via a terminal carried by the textile worker.
    "Name of textile worker". The textile worker sends the information "Name of the textile worker" which designates either the name of the textile worker or an identification signal. This information sent by the textile worker is used for the identification of the textile worker.
    "Status signal". The textile worker sends one of the three types of signals indicated below, namely: “Repair started”, “Repair completed” and “Request for instructions”, depending on his own working state.
    The “Repair started” signal is sent when the textile worker starts repairing a 300 dui weaving machine to be repaired by the textile worker. In response to this signal, the host computer 200 sends no response.
    The "Repair Complete" signal is sent when the textile worker completes the repair of a weaving machine 300 which has been repaired. In response to this signal, the host computer 200 returns, as a response, an instruction which takes up the unit number of the next weaving machine 300 which is to be repaired. The response from the host computer 200 may include information, such as the type of product produced by the weaving machine 300 and its downtime, in addition to the unit number of the next weaving machine 300 which is to be be repaired.
    The signal "request for instructions" is sent when the textile worker wants to know which machine, among the stopped weaving machines 300, is to be repaired as a priority over any one of the weaving machines 300. In response to this signal, the host computer 200 returns an instruction which designates the unit number of the next weaving machine 300 which is to be repaired, as a response.
    A weaving machine 300 which is affected by any one of the events indicated below, more specifically "Operation shutdown", "Operation start" and "Automatic repair inapplicable" sends the information together with its service number. drive to host computer 200.
    The "Stop Operation" message is sent from a weaving machine 300 whose operation has stopped due to an abnormality and failure.
    The message "Starting operation" is sent from a weaving machine 300 which has started its operation.
    The message "Automatic repair inapplicable" is sent from a weaving machine 300 which has the automatic repair function, but has stopped in a state in which automatic repair cannot be applied.
    [State of the weaving machine 300] Hereinafter, the state of the weaving machine 300 will be described, from the perspective of the host computer 200, with reference to a state change diagram and a state table. Fig. 3 is a state change diagram illustrating changes in the state of the textile machine system 1, in accordance with the first embodiment of the present disclosure. Fig. 4 shows a state table showing the state of each of the weaving machines 300 which constitute the textile machine system 1, according to the first embodiment of the present disclosure.
    The changes of state will be described below in the change of state diagram that Von represents in FIG. 3.
    In Figure 3, the term "receiving information" refers to the fact that the weaving machine 300 transmits "information" and the host computer 200 receives "information". It should be noted that the term “information” corresponds to the messages “Operation stop”, “Operation start” and “Automatic repair inapplicable” described above. The host computer 200 establishes the state "Status: Operational / Repair Supported: NA" for the state of a weaving machine 300 which reflects normal operation since its activation.
    When the host computer 200 receives information with the message "Starting operation" from a weaving machine 300 which has been repaired after it has shut down, the host computer 200 establishes the state of operation. the weaving machine 300 as follows: "Status: Operation / Repair taken over: NA". When the host computer 200 receives an information whose message is "Start of operation" from a weaving machine 300 in the state "State: Stop / Repair supported: [Name of textile worker]", host computer 200 establishes the state "Status: Operational / Repair Supported: NA". When the host computer 200 receives information with the message "Stopping operation" from a weaving machine which does not have an automatic repair function, the host computer 200 changes the state of the weaving machine. 300 by changing from the state (State: Operation / Repair supported: NA "to the state" State: Shutdown / Repair supported: NA ". When the host computer 200 receives an information whose message is" Operation shutdown "From a weaving machine which has the automatic repair function, the host computer 200 changes the state of the weaving machine 300 from the state" State: Running / Repair supported : NA "in the state" State: Stop / Repair supported: Machine. "When the host computer 200 determines the need for repair of a weaving machine 300 in the state" State: Stop / Repair support: NA ”and assigns a textile worker to the weaving machine 300, the computer host 200 modifies the state of the weaving machine 300 from the state "Status: Operation / Repair supported: NA" to the state "Status: Shutdown / Repair supported: [Name of worker of textile] ". When the host computer 200 receives an item of information whose message is “Repair started” from a textile worker linked to a weaving machine 300 in the “State: Stop / Repair supported: NA” state, the host computer 200 changes the state of the weaving machine 300 to the state "Status: Shutdown / Repair Supported: [Textile Worker's Name]". When the host computer 200 receives an information whose message is "Starting operation" from a weaving machine 300 which has the automatic repair function in the state "State: Stop / Repair supported: Machine" , the host computer 200 changes the state of the Weaving machine 300 to the state "Status: Operational / Repair Supported: NA". When the host computer 200 receives information that indicates that a textile worker is starting repair of a weaving machine 300 other than a weaving machine 300 for which the textile worker is designated, the host computer 200 changes the state of the weaving machine 300 in the state "State: Stop / Repair supported: [Name of textile worker]" to change to the state "State: Stop / Repair supported: NA". When the host computer 200 receives information such as "Automatic repair inapplicable" from a weaving machine which has the automatic repair function in the "State: Stop / Repair supported: Machine" state, the host computer 200 changes the state of the weaving machine 300 to the state "Status: Shutdown / Repair Supported: NA".
    The host computer 200 manages the state as well as the person in charge of the repair for each of the weaving machines 300 which have undergone modifications according to the state change diagram illustrated in FIG. 3, for example. in the form of the state table shown in Figure 4. In the specific example shown in Figure 4, a weaving machine 300 which is designated by the name "unit 001" is found in the state "Status: Shutdown / Repair supported: Year.
    A weaving machine 300 which is designated by the designation "unit 001" is in the state "State: Operation / Repair supported: NA". A weaving machine 300 which is referred to as "unit 003" is in the "Status: Shutdown / Repair Supported: NA" state. A weaving machine 300 which is designated by the designation “unit 004” is in the state “Status: Stopped / Repair taken over: NA”. A weaving machine 300 which is designated by the designation "unit 005" is in the state "State: Stop / Repair taken over: B". A splitting machine 300 which is designated by the designation “unit 006” is in the state “Status: Shutdown / Repair taken over: Machine”. [Development of the determination table] Hereinafter, a determination table to which the control unit 201 of the host computer 200 refers, as a determination criteria in determining the machine, will be described from among the weaving machines 300 which is to be preferentially repaired when two or more weaving machines 300 are at a standstill, with reference to Fig. 5. Fig. 5 is a diagram which is intended to describe examples of the establishment. of the determination table according to the first embodiment of the present disclosure. In the determination table, a number of determination elements are established, determination conditions for each of said plural determination elements and an established determination order according to which the determination is carried out based on said plural determination elements. , as a criteria for determining when determining which machine among two weaving machines 300 or more, which is to be repaired, when said two weaving machines 300 or more fail.
    In the determination table shown in FIG. 5, said several determination elements, the determination conditions for each of the determination elements, as well as the determination order according to which the determination is carried out based on said several determinants are made as set out below. As elements of determination, for example, one can establish the type of product, the number of the unit, a zo travel time, a repair time specific to a cause, a total repair time, a threshold for the period of time which corresponds to the stopping of the machine, and a period of time which corresponds to the stopping of the machine. Hereinafter, a specific example of the determination table shown in FIG. 5 will be described.
    For the first priority in the order of determination, the following is established as an element: "Determination element: type of product", and priority is given to the weaving machine 300 which manufactures the type of product A.
    For the second priority in the order of determination, the following is established as an element: "Determination element: unit number", and priority is given to the weaving machines 300 which carry the unit numbers 3001, 3206 and 3303.
    For the third priority in the order of determination, the following is established as an item: "Determination item: travel time" and priority is given to a weaving machine 300 which requires a shorter travel time on the part. of the textile worker to move to the weaving machine 300 which needs to be repaired. It should be noted that the travel time represents a relative value among said several weaving machines 300 and that it is not limited to an absolute time.
    For the fourth priority in the order of determination, the following is established as an item: "Determination item: cause-specific repair time", and priority is given to the weaving machine 300 which is stopped due to a fault. specific cause which requires a shorter repair time, the cause-specific repair time being established as follows: [warp yarn, weft yarn, manual operation, selvage, others} = (10, 3, 5, 7, 1} Repair time is a relative value among the causes that cause weaving machines to break down, and it is not limited to an absolute time.
    For the fifth priority in the order of determination, the following is established as an element: "Determination element: total repair time", the total repair time being calculated by adding the travel time to the repair time specific to a specific one. cause, and priority is given to a weaving machine 300 which requires a shorter total repair time.
    For the sixth priority in the order of determination, the following is established as an element: "Determination element: threshold time period of twenty minutes" and priority is given to a weaving machine 300, the stopping time of which is greater than twenty minutes.
    For the seventh priority in the order of determination, the following is set as an element: "Determination element: machine downtime", and priority is given to a weaving machine 300 which has a duration of longer machine stop.
    Another example of the construction of the determination table will be described with reference to Fig. 6. Fig. 6 shows a view which is for explaining an example of the establishment of the determination table according to the first embodiment. of this disclosure. In the specific example of the determination table shown in FIG. 6, the priority is established as indicated below.
    For the first priority in the order of determination, the following is set as an item: "Determination item: unit number", and the first priority is given to a weaving machine 300 which is designated by the number d. unit 3001 and the second priority is given to weaving machines 300 which are designated by unit numbers 3206 and 3303.
    For the second priority in the order of determination, the following is established as an element: "Determination element: product type", and the first priority is given to the weaving machines 300 which manufacture the product type A and the type of product C, and the second priority is given to the 300 weaving machines that make product type D.
    For the third priority in the order of determination, the following is established as an element: "Determination element: total repair time", the total repair time being calculated by adding the travel time to the specific repair time for a specific one. cause, and priority is given to the weaving machines 300 which require a shorter total repair time. As shown in Figs. 5 and 6, an administrator OR a person who is responsible for the textile machine system 1 can arbitrarily set said plural determining elements, the determining conditions for the respective determining elements, as well as the setting. 'order of determination according to which the determination is carried out by basing itself on said several determination elements in the determination table. [Calculation of travel time] Hereinafter, the calculation of travel time for the textile worker 10 which corresponds to a worker who is to travel to the repair destination will be described with reference to Fig. 7. Fig. 7 is a view which is intended to describe the movement of the worker in the textile machine system 1, according to the first embodiment of the present disclosure.
    In FIG. 7, a case is illustrated in which there are thirty-six weaving machines 300, more precisely the unit numbers 3001 to 3006, the unit numbers 3101 to 3106, the unit numbers 3201 to 3206, the unit numbers unit numbers 3301 to 3306, unit numbers 3401 to 3406, unit numbers 3501 to 3506, the identity numbers of six weaving machines 300 being set from 0 to 5 in the X direction and the numbers identities of six weaving machines 300 being set from 0 to 5 in the Y direction.
    The host computer 200 determines the position of the textile worker 10 based on any position of the weaving machine 300 from which the textile worker 10 has transmitted the information which designates a repair completion, the position of the weaving machine 300 from which the textile worker 10 has transmitted the information which designates the instruction request, and the position determined by the terminal or by the radio frequency identification carried by the textile worker 10 , or on combinations of the elements listed above.
    In figure 7, we assume that the textile worker 10 is in the position corresponding to the coordinates (Xs, Ys} = {0, 0}. We can calculate the travel time Tm for the textile worker 10 necessary for its displacement from the coordinates (Xs, Ys} to the coordinates (Xm, Ym} of the respective weaving machines 300, as indicated below.
    When the travel speed of the textile worker 10 is constant, the travel time is proportional to the travel distance and the travel time is calculated as the travel distance in the passage.
    Further, since the dimension of the weaving machine 300 in Fig. 7 in the X direction is three times larger than that in the Y direction, the cox and oy coefficients are set as follows: {ox wy) = (3, 1}. Consequently, the travel time Tm is calculated as follows: Tm = ox | Xm-Xs | + oy | Ym-Ys | In this case, the width of the passage is not taken into account .
    The travel time Tm necessary for the movement of the textile worker 10 which occupies the position corresponding to the coordinates (0, 0} to each of the positions of the processing machines 300 is calculated as follows.
    It should be noted that one can use a relative value for the determination in the calculation of the displacement time Tm, and that one is not limited to an absolute time.
    The travel time Tm (3103) to unit 3103 is calculated as follows:
    Tm {3103} = 3 | 1-0 | +1 | 2-0 | = 5 The travel time Tm {3206] up to unit 3206 is calculated as follows: Tm ({3206) = 3 | 1-0 | +1 | 5-0 | = 8 Note that units 3103 and 3206 are arranged along the passage, and that Xm represents equal values. We calculate the travel time Tm ({3302) up to unit 3302 as follows: Tm ({3302} = 3 | 3-0 | +1 | 1-O | = 10 We calculate the travel time Tm { 3405) up to unit 3405 as follows: Tm (3405} = 3 | 3-0 | +1 | 4-0 | = 13 Note that units 3302 and 3405 are arranged along the passage, and that Xm represents equal values.
    Consequently, when the determination is carried out based on the element "Determination element: travel time", the priority is as follows: 3103> 3306> 3202> 3405. The priority can be subject to 'a detailed calculation when taking into account the width of the passage, the difference in height and the orentations of the weaving machines 300.
    [Example of a determination according to the cause-specific repair time] Hereinafter, a specific example of the calculation of the cause-specific repair time will be described, as well as the determination based on the specific repair time. cause, as shown in Figure 5. Cause-specific repair time, which is the amount of time that is required to repair a weaving machine that has stopped under the influence of a specific cause, represents a relative value among 300 weaving machines that have stopped for various causes, and it is not limited to absolute time. It is assumed that the weaving machines 300 which are designated by unit numbers 3103 and 3206 have stopped on the basis of a cause related to a "warp yarn", and that the weaving machines 300 which are designated by unit numbers 3302 and 3405 stopped based on a cause related to a weft thread ”. In this case, the cause-specific repair time for the 3103 unit is 10, the cause-specific repair time for the 3206 unit is 10, the cause-specific repair time for the unit. Unit 3302 is 3 and the cause-specific repair time for unit 3405 is 3.
    Consequently, when the determination is made based on the element "Determination element: cause-specific repair time", the priority is as follows: 3302 = 3405> 3103 = 3206.
    [Example of a determination which is based on the total repair time] Next, a specific example of the calculation of the total repair time and a determination which is based on the total repair time will be described. The total repair time for unit 3103 is equal to 15, which is obtained by the calculation: 5 + 10 = 15: the total repair time for unit 3206 is equal to 21, which is obtained by calculation: 11 + 10 = 21; the total repair time for unit 3302 is equal to 13, which is obtained by the calculation: 10 + 3 = 13; and the total repair time for unit 3405 is equal to 19, which Ion obtains by the calculation: 16 + 3 = 19. As a consequence, when the determination is made based on the element "Determination element : total repair time ”, the priority is as follows: 3302> 3103> 3405> 3206.
    [Operation] | Hereinafter, the processes for managing the operating states of the weaving machines 300 through the host computer 200 will be described. In the following description, the processing carried out by the control unit 201 of the loom will be described below. The host computer 200 will be described as the processing performed by the host computer 200. Similarly, the processing performed by the control unit 301 of the weaving machine 300 will be described as the processing implemented. work by the weaving machine 300.
    When the host computer 200 receives any information from a weaving machine 300 or from a textile worker, the host computer 200 changes the state of the corresponding weaving machine 300 according to the flow diagram. state change of Figure 3 and updates the data of the state table shown in Figure 4, depending on the changed state.
    The host computer 200 refers to the status table in Figure 4 and checks whether a weaving machine 300 has stopped and for which no textile worker has been assigned to repair.
    When the host computer 200 refers to the prop table in Figure 4 and discovers that a single weaving machine 307 stopped for the repair of which no repairing textile worker has been appointed , the host computer 200 sends a notification to a textile worker who is available for repair work directing to repair the one and only weaving machine 300 that has stopped.
    The host computer 200 sends the above notification to the operating unit 320 of the weaving machine 300 to which the textile worker has just been assigned for repair, or to the terminal carried by the worker. textile.
    When the position of the textile worker is unknown at the time of the above notification, the host computer 200 can implement simultaneous notification using the operating units 320 of all of the weaving machines 300 or it can use other means of notification, such as internal distribution.
    Further, when there are two stopped smoothing machines 300 or more for the repair of which no textile worker has been appointed, the host computer 200 refers to the determination table in Fig. 5 and FIG. 6, which is shown by way of example, and determines a weaving machine 300 which is to be repaired in a preferential manner.
    The host computer 200 refers to the determination table shown in Fig. 5 or Fig. 6 shown by way of example for determining a weaving machine 300 which needs to be repaired in such a way. preferential based on the determining element of the first order of determination in the determination table.
    When the host computer 200 cannot determine a weaving machine 300 which is to be repaired as a priority based on the determining element set as the first priority in the order of determination in the determination table, the host computer 200 makes a determination based on the determination items that have been set as a second priority and as a subsequent priority so as to determine a weaving machine 300 that needs to be repaired as a priority.
    In the determination table illustrated by way of example in FIG. 5, the host computer 200 makes a determination according to the determination order which has been established in the following order, namely: the type of product, the unit number, travel time, cause-specific repair time, total repair time, the threshold for the amount of time that corresponds to the machine shutdown, and the time that corresponds to stopping the machine. In the determination table illustrated by way of example in Fig. 6, the host computer 200 makes a determination according to the determination order which has been established in the following order, namely: the number of the unit, product type and total repair time.
    In the determination table, another determination condition can be set for the same determination item, which is set as another priority in the determination order. For example, in the determination table that Von represents in FIG. 6, although the element "Determination element: product type" has been established for the second priority, the element "Determination element: Product type / Condition of determination: Product Type B or Product Type B "can be established for the fourth priority.
    In the event that the determination is not completed, even if the determination continues to the determining element to which the lowest priority is related, the host computer 200 determines a weaving machine mode 300 that is to be. repaired as a priority according to a predetermined criterion. The predetermined criterion represents, for example, the determination of the weaving machine 300 which has the smallest unit number among two or more weaving machines.
    The host computer 200 indicates to the textile worker that he can start the repair job of the weaving machine 300 which has been determined to be to be repaired as a priority. The host computer 200 sends this notification to the operating unit 320 of the weaving machine 300 for the repair of which the textile worker has been assigned immediately before or to the terminal carried by the textile worker. Further, when the position of the textile worker is not known at the time of the above notification, the host computer 200 can perform simultaneous notification using the operating units 320 of all of the weaving machines. 300 or else it can use other means of notification, such as for example an internal broadcast. When the host computer 200 receives the notification indicating the start of repair related to a weaving machine 300, the host computer 200 changes the state of the weaving machine 300 according to the state change diagram of the weaving machine. FIG. 3 and updates the data of the state table shown in FIG. 4 according to the state which has been modified.
    In the description given above, the host computer 200 may implement another process by performing any of the processes selected from receiving information, updating data, determining and notifying. .
    As the host computer 200 continues to manage the operating states of the weaving machines 300, the host computer 200 repeatedly implements each of the processes which have been described above. When the host computer 200 shuts down all of the weaving machines 300 which are managed by the host computer 200, the host computer 200 performs necessary shutdown processing and terminates the processes noted above.
    The procedure of sending and receiving information between the host computer 200 and the weaving machines 300 will be described with reference to a flowchart shown in Figure 8 which illustrates signal exchanges in the system. of textile machines 1, in accordance with the first embodiment of the present disclosure.
    During a step which is represented in the state table (a) in FIG. 8, the weaving machine 300 which is designated by the unit number 002 is in operation and the weaving machines 300 which are designated by the unit numbers 001, 003, 004, 005 and 006 are stopped. In addition, unit 001 is being repaired by textile worker A, unit 005 is being repaired by textile worker B, unit 006 is being repaired automatically and textile workers have not yet been assigned to repair units 003 and 004.
    During a step represented in the state table [b} in figure 8, the repair of unit 005 by textile worker B has been completed, and textile worker B transmits l [Repair Complete] information from unit 005 to host computer 200. At this time, textile worker B becomes available for a new repair job.
    In response to this information, the host computer 200 sends the status: "Status: Repair Complete / Repair Supported: NA" for unit 005 of weaving machines 300 in the status table. Further, by referring to the determination table, the host computer 200 determines that unit 004 is to be repaired as a priority among units 003 and 004 and sends the notification to the textile site worker. B. Host computer 200 sends the notification for fabric worker B to unit 005 that fabric worker B was repairing directly before.
    During a step represented in the state table (c} of figure 8, a textile worker C who was not present until he was currently available for a new job repair and transmits the information [Request for instructions] from unit 004 to host computer 200. This case occurs when textile worker C arrives for work, returns from a station wagon, is called to for support purposes, and the like.
    In response to this information, the host computer 200 notifies the textile worker C that the unit 003 is stopped and that no textile worker in charge of the repair has been appointed.
    The host computer 200 sends the notification for the textile worker C to the unit 004 from which the textile worker C sent the request for instructions. Additionally, the host computer 200 establishes the status: "Status: Shutdown / Repair Supported: Textile Worker C" for unit 003 in the status table.
    During a step which is represented in the state table {dad} of FIG. 8, it is observed that the unit 006 which has the automatic repair function and which has started a repair is in a state wherein automatic repair cannot be applied and Unit 006 sends the information [Automatic repair inapplicable] to host computer 200. In response to this information, host computer 200 sets the state: "State: Stopped / Repair Supported: NA ”for unit 006 in the status table.
    During a step which is represented in the state table {(e) of FIG. 8, the textile worker B starts repairing unit 004 and sends the message "Repair started" from unit 004 to host computer 200. Since host computer 200 has already designated textile worker B to take over repair of unit 004, the adaptation in the information table is not implemented.
    During a step represented in the state table (f] of figure 8, the textile worker A starts repairing unit 006 and sends the message “Repair started” from there. unit 006 to the host computer 200. In this case, the textile worker who has been assigned to take over the repair of unit 001 stops unit 001, although the repair is not completed. and begins repairing unit 006. In response to this information, host computer 200 establishes the “Status: Shutdown / Repair Supported: NA” state for unit 001 and the “Status: Shutdown” state. / Repair supported: Textile worker A "for unit 006 in the state table. (Effects obtained by this embodiment) As described, the effects shown below can be obtained at the intervention of the first embodiment of the present disclosure.
    In the context of the textile machine system 1 and the host computer 200 of the first embodiment, the determination table in which said several determination elements are provided, the determination conditions for each of said several determination elements, as well as the order of determination according to which the determination is made based on said plural determination elements, as determination criteria for determining a weaving machine 300 which is to be repaired as a priority, and when two weaving machines 300 or more stop, the host computer 200 determines which machine, of the weaving machines 300, is to be repaired based on the determination table. For this reason, when two 300 or more weaving machines are at a standstill, detailed requests from users can be met by determining which weaving machine should be repaired by referencing. basing not only on the point of view of productivity, but also on the conditions of determination, such as for example a specific type of product or a specific unit among weaving machines
    300.
    Accordingly, a 300 machine which is to be repaired can be flexibly determined based on arbitrary settings, such as for example a 300 weaving machine which produces the type of product which is to be preferentially shipped, a weaving machine. weaving machine 300 which manufactures the kind of product which is to be released in an emergency, a weaving machine 300 which shortens the repair time, and the like. Further, a temporary rewrite of the determination table allows a weaving machine 300 to be determined which needs to be repaired while taking into account temporary detailed requests.
    In the context of the textile machine system 1 and the host computer 200 of the first embodiment, when the host computer 200 determines a weaving machine 300 which needs to be repaired, the operating states, for example the working state and shutdown state, as well as aui / guoi is responsible for the repair are clarified for each of the 300 weaving machines, which prevents multiple textile workers from being assigned to repair the same machine weaving machine 300, even when several textile workers are present in the same area.
    In the context of the textile machine system 1 and the host computer 200 of the first embodiment, when the host computer 200 determines a weaving machine 300 which is to be repaired, the weaving machine 300 which has the function repairer is considered to be in charge of the repair itself. Accordingly, when the host computer 200 designates a textile worker to take over the repair for each of the stationary weaving machines 300, the configuration of the first embodiment avoids designating a textile worker for repair of the weaving machine 300 which has the automatic repair function.
    [Other Embodiments] Hereinafter, a modification of the first embodiment of the present disclosure will be described.
    In the above description, the weaving machine 300 has been described as a specific example of a textile machine, but the present disclosure is not limited thereto. For example, the first embodiment of the present disclosure can be applied to a textile machine system which includes spinning machines such as a ring configuration spinning machine in place of the weaving machine 300. When the first embodiment which has been described above applies to spinning machines, the determining element can be set not only for the units, but also for each spindle.
    In the above description, although the criteria for priority setting conditions are established in the determination table for determining which weaving machine is to be repaired, the present disclosure is not there. limited.
    For example, a condition that does not relate to priority can be set in the determination element.
    As an example, the condition "Determination element: Product type" is established and the priority may relate to whether a weaving machine which produces product type A is to be repaired as a priority. , and that a weaving machine which manufactures the product type F, among the ioiality of product types, is to be repaired last.
    In addition, the priority may relate to a longer period of time for travel time and for repair time.
    The textile worker operation of sending the name of the textile worker or the identification signal from the weaving machine 300 can be performed by the host computer 200 using various techniques of authentication such as, for example, biometric authentication using fingerprints, iris, veins or the like, identity authentication using identity cards or radio frequency identification, or the like, in addition to entering the name textile worker or the identification signal from the operating unit 320 of the weaving machine 300. Alternatively, the host computer 200 may recognize the textile worker in charge of the repair from the repair template. of the weaving machine 300 or the like.
    Further, the host computer 200 can analyze an image from a surveillance camera which monitors the premises in which the textile machine system 1 is installed and can identify the textile worker using various techniques such as, for example, the face authentication using face image, appearance authentication using clothing, corpore type! and the like, gait authentication to specify individuality relating to displacement, and the like.
    For biometric authentication, identity authentication, repair pattern recognition, image analysis authentication, and the like, various techniques other than the specific examples which have been described above can be used, or several techniques can be used in combination.
