    The invention relates to an arrangement for locating electronic devices in a room and a shelf device with such an arrangement.
    In many applications, location-based data is collected or evaluated. EP 0 568 180 B1 (DE 69 326 376 T2) discloses an inventory management system which, for example, serves to check prices of goods received on a shelf. This electronic price displays are used, which are attached to rails of the shelf. Each rail is associated with a controller that contains information about the location of the rail and communicates with a central computer via an electrical connection or radio connection. The price displays are connected to the controller via electrical lines.
    A busbar with combined power and data lines for the supply of displays is known from EP 1 170 835 A1. The displays are fastened to the rail via snap-in connections, which are designed to be elastic enough to allow the displays to be assembled and disassembled by deformation.
    The arrangements known from the prior art only recognize on which rail an electronic device, such as e.g. a price display, is mounted. But if long rails are used and the electronic devices often change location, must be searched manually according to the state of the art or the devices must be equipped with sophisticated sensors and tracking software. For example, it is expensive in large warehouses and factories to manually monitor the levels of individual storage bins and containers, which is associated with a designed as an electronic device label, especially if containers can be moved with mounting hardware by the technicians. An automatic monitoring of the positions of the individual containers with associated labels and the levels of individual containers and shelves with the previously known means, however, is associated with great expense or effort, since a precise location of the devices is possible only with complicated sensors.
    Object of the present invention is therefore to realize an arrangement for the localization of electronic devices on long rails in a room and a rack device to allow automatic position detection of rail mounted electronic devices, especially when devices are frequently moved , The arrangement should be easy to assemble and disassemble and should be inexpensive to produce.
    This object is achieved by an arrangement for locating electronic devices in a room with the characterizing features of the main claim in conjunction with the features of the preamble.
    According to the invention, the arrangement for localization of electronic devices in a room, at least one rail, which is arranged in space and at least one electronic device that is mountable on the rail. In this case, the rail has a coding along its longitudinal direction, by which a coding pattern is defined, which is applied to the rail. The coding pattern changes depending on the position on the rail. The coding can preferably be applied continuously on the rail. The relationship between coding pattern and position is determined by a mapping function. The electronic device which can be mounted on the rail comprises a scanning device which detects the coding pattern applied to the rail at the location of the electronic device. A determination unit is designed to determine the position of the device in space on the basis of the detected coding pattern and the assignment function. The assignment function can be designed differently depending on the coding, for example as a mathematical algorithm, as an assignment table or the like.
    The inventive arrangement, it is possible to automatically detect the position of the electronic devices on a rail. As a result, in particular in application scenarios in which the electronic devices frequently change location, considerable savings can be made since the devices do not have to be searched manually. If a container associated with the electronic device is moved, for example by a fitter, then only the associated electronic device has to be taken along and fixed on the rail at the new location of the container.
    Advantageous developments and improvements of the inventive arrangement are described in the dependent claims.
    It is advantageous in the context of the invention that the coding pattern is applied as electrically conductive and non-conductive surfaces on the rail, wherein the coding pattern is formed differently over the length of the rail. In this case, conducting surfaces can be, for example, electrical lines in different forms, on which the coding pattern is stored digitally, for example in the form of binary or tri-state codes. The electrically conductive and non-conductive surfaces is assigned at least one, preferably a plurality of scanning regions for detecting the electrical state of the surfaces. The changes in the, as electrically conductive and non-conductive surfaces trained on the rail, coding patterns can be continuous or, based on a fixed screening, discrete, with a discrete change of a digital coding pattern is preferred based on a predetermined screening. The screening can be designed differently depending on the field of application, for example it is possible that the coding pattern on the rail changes every 5 cm, every 20 cm or every 60 cm. Decisive here is the size of the shelves or containers used in the specific application. If the shelves or containers are large, then only a coarse screening of the coding pattern is required, which offers the advantage that due to the smaller address space of the coding, simpler encodings and scanners can be used. In the case of small shelves or containers, more elaborate codes and scanning devices are used according to the invention in order to meet the requirements.
    According to a further embodiment, the coding pattern can be represented by at least one resistance track applied to the rail with resistance value dependent on the position on the rail. For example, in this case a material such as Konstatan be used, which has a good electrical resistance measurable, which increases by increasing the distance between the measuring points. For example, the resistance between two resistance paths is measured, which are connected together at one end. By connecting the resistance path at one end of the rail to a supply line having a very low electrical resistance, the resistance can then be measured by the microcontroller of the device and converted into a digital value. This is then compared with values stored, for example, in a table to calculate the distance to the end of the rail. The assignment function establishes the connection between resistance value and position on the rail. This embodiment does not require extensive coding and decoding.
    A further development of the inventive arrangement provides that the coding pattern is represented by at least two electrical lines applied to the rail, which are fed with signals of different frequency, and the dependent on the position on the rail phase difference between the two lines. Here, two applied on the rail electrical lines are fed with signals of different frequencies. By measuring the phase difference, the position on the rail can then be determined. It may be advantageous that the already existing data and / or supply lines can be used as frequency lines, thus a narrow construction of the rail is possible.
    A further embodiment provides that the coding pattern has a plurality of applied to the rail optical reflection elements, which are formed differently over the length of the rail. In this case, the reflection elements can be, for example, colored or achromatic markings or mirror elements, which in turn change continuously or with a predetermined rastering along the rail. Due to this design of the coding pattern, an absolute coding within a given address space is possible, since different rails can be provided with different coding patterns.
    According to the invention it is provided that the scanning device comprises at least one, preferably a plurality of electrical contact elements and / or optical sensor elements, wherein the plurality of contact elements are arranged parallel in the transverse direction to the rail and / or serially in the longitudinal direction of the rail. In order to detect an electrical connection, a resistance, a phase difference or a digital coding according to the previous development variants, contact elements, for example in the form of inexpensive spring contacts, can be used. As sensors, for example, light or color sensors can be used to realize a coding pattern formed by a plurality of optical reflection elements. Due to the number and arrangement of the electrical contact elements and sensor elements corresponding to different scanning ranges different complex coding can be realized.
    Furthermore, it is advantageous in the context of the invention that along the rail an electrical supply line for a power supply of the at least one electronic device and optionally a data line for the transmission of data is applied. Through this supply line, the power supply of the electronic devices and / or a data line is realized. The power supply takes place according to the invention by DC or AC voltage via conductive surfaces, which are applied to the rail. The bidirectional communication between electronic devices and a control device and / or data processing unit takes place according to the invention via the supply lines or via a separate data line. In the case of communication via the supply lines, the data information is coded, for example, according to the 1-wire principle in parasitic mode into the supply lines. A power supply of the devices via the rail is advantageous because it is an individual, autonomous power supply of the individual devices, for example by batteries, not required. It is also possible within the meaning of the invention that the coding pattern or a part of the coding pattern is formed by the supply line.
    According to the invention it is also advantageous if the electronic device comprises the determination unit which stores the assignment function and thus creates the assignment of detected coding pattern and position in space. For this purpose, it is advantageous if the device includes a microprocessor and a persistent memory.
    It is also possible here that the assignment function in addition to the detected coding pattern also receives a marking of the rail and thus the absolute position of the device in space from a combination of the position of the rail in space and the relative position of the device on the rail is determined. This is particularly advantageous when a relative coding, for example by a resistance line or a phase difference measurement is used. It is also possible to use several identical rails for cost reasons, and then to determine the absolute position of the electronic device in the room as a combination of the position of the rail and the relative position of the device.
    According to the invention, the electronic device may also include a display unit and / or an input unit and / or a measuring device for measuring a voltage, a current, a resistance and / or a phase or phase difference and / or a sensor arrangement and / or a transmitting / receiving unit exhibit. As a result, a variety of functions of the electronic device can be realized. It can be a device for entering and / or displaying data. In addition, the electronic device may be designed for optical and / or acoustic detection or monitoring, or it may be a sensor device that receives measured values from the environment. Here, for example, sensors or controls are provided by the removal of articles, such as screws or other mounting hardware, is detected from a container or shelf.
    It is also possible to couple the devices and shelves and / or containers with a level indicator. This can be integrated in the device or container, for example in the form of sensors, or it can be firmly mounted in the room, thus located outside of the device and container. In this variant, external sensor and device and container are assigned to each other via the position determination.
    An embodiment may include a temperature sensor that detects, for example, the temperature of stored goods. Also, the device may have a transmitting and / or receiving unit. Due to the large number of possible devices, the inventive arrangement is versatile applicable.
    According to the invention, the at least one rail may be associated with a control device to which the supply line and / or data line is connected. By the control device, the power supply of the electronic devices and the data transmission can be controlled. In accordance with a possible weather formation of the arrangement according to the invention, the control unit may also comprise the determination unit, by means of which, with the aid of the assignment function, the assignment of the detected coding pattern and position takes place in the room. The control device may in turn have a transmitting and / or receiving unit and be connected to a data processing system.
    According to the invention it is provided that the rail is as flat and inexpensive to produce. Here, a flat band profile is preferably used, which is preferably made of extruded aluminum or extruded plastic, or more generally of extruded or rolled parts that are glued or welded during manufacture. As a result, no milled parts or elaborate reworking are needed. This offers, in addition to cost savings in manufacturing, the advantage that the rail is robust, dirt-resistant and possible wear-free, since no maintenance-intensive parts and / or dirt-prone grooves are present. According to the invention, the thickness of the rail is less than 1 cm, it is advantageous if the rail is 3 mm thick, and is at most as wide as the device mounted thereon. It is also advantageous if device and rail together are a thickness of less than 2cm, preferably not thicker than 1cm, preferably less than 5-6mm. Preferably, the rail is at most as wide as the end face of a shelf to which it is attached, for example, a maximum of 5-10cm wide, for example, 5cm, 8cm or 10cm wide. On plastic rails is also particularly advantageous that on these, due to their insulating properties, the lines can be applied directly. The flat and / or narrow structure prevents the rail from interfering with the handling of the environment in electronic devices and tearing down electronic devices.
    The rail in this case comprises a fastening device with which the rail in the room, for example on a wall or on a shelf, is mounted. In addition, the rail on the side on which the devices are mounted, a holding device for mounting the electronic devices, which in turn have a corresponding holding device. The holding device and / or the corresponding holding device are provided with centering elements. Due to the centering, a mis-assembly of electronic devices is excluded when the electronic devices are mounted on the fixture. The centering elements are preferably formed in the longitudinal direction of the rail, so that a smooth longitudinal displacement of the device on the rail is possible.
    The fastening device for the rail can be formed here as a magnetic or mechanical fastening device. An advantage of the magnetic fastening device is its very flat structure. An advantage of the mechanical fastening device is that it can also be used on non-metallic substrates.
    Also, it is advantageous according to the invention, when the holding device and the corresponding holding device, which may have the centering, are designed as a magnetic or mechanical holding device. It is also advantageous to the magnetic holding device that it has a very flat structure, while the mechanical attachment is more robust, so that accidental tearing of the devices is more difficult. The centering elements may in this case be formed by corresponding engagement elements, for example in the form of grooves or profiles, or be realized solely by the magnetic force, for example by means of stepwise arranged magnets.
    By a magnetic holding device, the device is pulled during assembly by the magnetic force to the rail. This makes a one-handed and tool-free assembly and disassembly possible. In a mechanical holding device, the assembly and disassembly can also be done with one hand and without tools, for example, by a slightly elastic rail, in which the devices are pressed in and removed by train again. Also, a feather key connection is possible, in which the assembly and disassembly are carried out by one-handed operation of a device located on the mechanism. It is also advantageous that such a mounting is possible at any free point of the rail, a threading at the end of the rail is not required.
    According to the invention, it is provided in the interplay of rail and device that the device is one-handed and tool-mountable, and that the device is one-handed on the rail slidably. This is of great importance, since the devices must be additionally moved when moving containers or shelves.
    The application of the coding pattern, the electrical supply and / or data lines to the rail is carried out according to an inventive development by applied to a flat, flexible carrier conductor tracks and conductor surfaces. The carrier is then in turn mounted on the band-profile rail. It is advantageous here that the production of the carrier takes place separately from the production of the remaining rail, which allows a more effective operation.
    Alternatively, it is possible according to a further development of the invention possible that the coding pattern as well as the supply and / or data lines are applied or printed with a conductive ink or paste directly on the designed as a band profile rail. This saves the use of an additional carrier.
    In the embodiment of the coding, it is advantageous according to the invention if it is based on the principle of block codes, convolutional codes and / or turbo codes. Each individual encoding is designed based on the size of the required address space. If the address space is small enough, parallel coding, for example based on the principle of block codes, can be performed. If, due to a large address space, the parallel lines are insufficient, serial coding is used. In this case, according to the invention, convolutional codes or turbo codes are preferred, since these enable unambiguous position recognition even with overlapping code words. For the decoding of the serial coding, according to the invention an assignment function based on Viterbi's algorithm can be used.
    An application of the inventive arrangement for locating the electronic devices is a shelf device with a plurality of attached to a support frame shelf elements, wherein the shelf elements each have the rails are attached to which a plurality of electronic devices are mounted. The electronic devices can be assigned to shelves or stored on the shelf elements containers.

    In Fig. 1, a preferred embodiment of the present invention is shown on the basis of a shelf device. Here, a support frame 101 is provided, on which a plurality of, in the figure by rails 102 hidden, shelf elements, e.g. Shelves are mounted. Along the shelf elements, the rails 102 are fixed to their end faces, on which in turn electronic devices 103 are mounted. In this case, the rail 102 is narrow and projects beyond the front side of the shelf elements to a minimum of a few millimeters in order to prevent accidental tearing off of the rails 102. The electronic device 103 is connected to the rail 102 via rear contacts, preferably spring contacts. Each electronic device 103 is assigned to a container 105, 105 and indicates the current position of the respective container. Depending on the content, the containers may be large containers 105 or small containers 105. The size of the smallest possible container that can be placed on a shelf element, provides a grid 107, through which various positions for mounting the devices 103 are defined. The grid 107 and thus the size of the positions 107 can also be different within a rail or at different rails of the same support frame. By the screening 107 thus a distance of the containers 105, 105 and electronic devices 103 is specified. If a larger container 105 is placed on a small-screen shelf element 107, then some rasters and thus positions 107 on the rail 102 remain free. By means of the control device 106 it can be detected which size a container 105 has and how many previous and / or subsequent rasters 107 must remain free. If multiple devices are placed within a grid 107 or within the multiple grid 107 covered by a large bin 105, an error signal may be provided by device 103 or controller 106.
    The rails 102 have schematically indicated scanning areas 104. The rails 102 belonging to a support frame 101 are connected to a control device 106, via which the supply and the traffic of the rails 102 and the electronic devices 103 mounted thereon are controlled. The control device 106 may be connected to a data processing device, not shown. This connection can be realized by a data line or by a radio link.
    On the rail 102, a coding pattern (to be described later) dependent on the location on the rail 102 is applied, which is detected by the electronic devices 103. For this purpose, the device 103 has a scanning device (described later) and a determination unit (not shown), on the basis of which the determination unit determines the position of the device on the rail 102 on the basis of an assignment function. In this embodiment, the determination unit is arranged in the device 103, but it may also be provided in the control device 106.
    In the described embodiment, the devices 103 are designed as picking devices and are provided with a display unit 108 and contain sensors that detect the removal of articles from the individual containers 105,105. Thus, a semi-automatic realization of storage can be achieved. Instead of sensors, the devices 103 may also have a button that registers the removal of an article from the container 105, 105 when printed.
    According to a further embodiment, it is also possible that the devices 103 are coupled to a level indicator of the container 105,105, monitor the level, for example, based on optical sensors, weight sensors or acceleration sensors in the device 103 or in the container 105,105. In this case, it is also possible to monitor the filling level of the containers 105, 105 with the aid of optical sensors which are fixed immovably in the room, for example on the shelf or support frame 101. Here, the position determined by the electronic device 103 of a container 105, 105 in space determines at which external optical sensor a container 105, 105 is currently located. The information about the level of the containers 105,105 are supplied via the data line 109 to the control device 106, which can transmit this information together with the grid 107 of the container 105,105 to an external data processing system.
    2, a cross section through an embodiment of the electronic device 103 is shown. The electronic device 103 is very flat, preferably less than 1 cm thick, and includes a housing 204, which is inexpensive, for example made of plastic. The electronic device 103 has a display 108, such as a liquid crystal display, and a cover glass 205.
    On the back, the electronic device 103 has a plurality of, for example, formed as contact springs contacts 201 and asymmetric centering 206, formed in this case in the form of a tongue and groove combination, which engage in the assembly in corresponding centering elements 206 of the rail 102. This is also explained in more detail in the descriptions of FIGS. 3 a, 3 b and 4. By means of a holding device, which is implemented in this case by embedded in the housing 204 magnets 203, the electronic device 103 is attached to the rail 102.
    Furthermore, the electronic device 103 includes an internal electronics unit 202, for example consisting of a circuit board and other electronics. The internal electronic unit 202 comprises a microcontroller, a persistent data storage and controls the display of the electronic device 103, in other embodiments also the input or possible sensors. Moreover, the internal electronic unit 202 detects the coding pattern (described later) on the rail 102 by the contacts 201. The internal electronic unit 202 in this embodiment also includes the determining unit which determines the position in space based on the mapping function from the detected coding pattern.
    In Fig. 3, two different embodiments of a magnetic holding device are shown, with which an electronic device 103 is mounted on a rail 102. In the embodiment in Fig. 3a, the electronic device 103 is fixed to the rail 102 with a magnet 203 into which a thin sheet metal or metal strip 301 has been inserted for this purpose. On the rail 102, there are a plurality of conductive surfaces 302 which are contacted by the contacts 201 during assembly. Due to the centering elements 206, which are formed in this case as asymmetrical lateral guides, incorrect assembly is excluded. When assembled, the electronic device 103 is pulled by the magnetic force on the rail 102, wherein the contacts 201 are pressed or deformed.
    In a further embodiment, the electronic device 103, as shown in Fig. 3b, two magnets 203 and in the rail 102 at the corresponding location two thin sheets or metal strips 301 are embedded. In FIG. 3b, through the contacts 201 facing at least partially sensing regions 104, both conductive 302 and non-conductive 303 surfaces on the rail 102 are contacted, thereby establishing an electrical connection to the supply line or data line and / or the encoding pattern at the sensing regions 104 is scanned. The centering device 206 is formed in this embodiment by asymmetrical lateral guides and by a tongue and groove connection, which engages in the assembly.
    Fig. 4 shows that a faulty assembly is precluded by the centering elements 206.
    In Fig. 5 various embodiments of the coding and contacting of the rail 102 through the contacts 201 of the electronic device 103 are shown. In Fig. 5a is shown as a preferred embodiment, the digital parallel coding. Here, on the rail 102, a digital coding pattern 501 is applied, which extends continuously or continuously over the length of the rail. Now, if the electronic device 103, shown here schematically as an outline, mounted on the rail 102, the scanning device formed as spring contacts 201 contacts the coding pattern 501 of the rail 102 at a plurality of locations which are parallel to each other along a cross section of the rail 102. In this case, an enlargement of the address space by a factor of 2 or 3, depending on whether a binary or tri-state coding is used, can be achieved by each contact 201 of the scanning device. Furthermore, it is possible to use the supply and / or data lines also for coding. In this case, the supply and / or data lines are interrupted so that the supply and sampling area 104 share the functions.
    If a larger address space is needed and the width of the rail 102 can not be increased or should, as it would then, for example, too wide for mounting on the front page given shelves, so a serial coding, as shown in Fig. 5b shown to be used. In this case, in addition to the spring contacts 201 formed in the transverse direction to the rail 102, further spring contacts 201 formed in the longitudinal direction of the rail 102 are present. As a result, the detection of the coding pattern 501 takes place serially, which allows a larger address space. In order to be able to unambiguously associate the detected coding patterns 501, even with serial coding, with a grid 107 and thus a position in space, folding or turbo codes are preferably used according to the invention, which can then be decoded using Viterbi's algorithm.
    In the case of discrete coding patterns 501, according to one exemplary embodiment, it is also possible to place a device 103 in such a way that it extends over two coding patterns 501 on the rail 102. In this case, with parallel coding, only one of the two coding patterns 501 is detected, namely that which is located under the rear-side contacts 201 of the electronic device 103. In serial encoding, it is possible for some contacts 201 to detect the left and some contacts 201 the right encoding pattern. However, this is not a problem by using appropriate encodings, such as convolutional and / or turbo codes in combination with Viterbi's algorithm for decoding, the raster 107 on the track 102 and the position in space can still be uniquely determined.
    FIG. 6 shows plan views of the rail 102 according to one of the preferred embodiments. In FIGS. 6a, 6b and 6c, the rail 102 contains in each case a data line 601, which is realized, for example, via a 1-wire protocol on the middle line, and in each case one positive and negative supply line 602, 603, which forms the rail 102 supply for example via DC voltage with power. The coding is performed by a digital coding pattern 501, wherein the digital scanning regions 604-1, 604-2, 604-3, 604-4 are located at the edge of the rail (see FIGS. 6b and 6c), between the supply and data lines 601 , 602, 603 (see FIGS. 6a, 6b and 6c) and side by side (see FIG. 6c).
    The digital coding takes place depending on the placement of the digital scanning range based on a binary or tri-state coding. Herein, binary information may be encoded on each digital point of a scan area 604-1 located on the edge or, as in FIG. 6c adjacent to another scan area 604-1, 604-2, by having the scan area at that point coincident with the adjacent scan area 604-1, 604-2 Supply or data line 601, 602, 603 is connected or not. If a sample area, such as 604-1 in FIG. 6a, is located between data and supply lines 601, 602, 603, tertiary information may be coded at any point by the digital tri-state principle Scanning area is connected at this point either to the one adjacent line or to the adjacent line or to neither of the two lines.
    In Fig. 6 also possible based on the screening 107 of the coding grid 107 are shown by dashed lines and capital letters.
    In Fig. 7, a further preferred embodiment of the rail 102 is shown. Here, the coding is effected by optical reflection elements 702, which may be formed, for example, as a color pattern or mirror elements. In addition to a data line 601 and positive and negative supply lines 602, 603, a plurality of optical scanning regions 701-1, 701-2 are present on the rail 102, which are detected by color or light sensors located on the electronic device.
    A further preferred embodiment of the rail 102 is shown in Fig. 8. In this case, the position on the rail 102 is coded by a phase difference. In Fig. 8a a temporary phase difference measurement is shown alternating to the communication. In this case, a frequency 801 is applied as a reference value to a supply line 602 and the second frequency 802 is introduced in alternation with the data line 601. The frequencies and thus their phase difference can then be measured by the electronic device 103 at two locations 803, 804 of the supply line 602 and the data line 601 along a cross section of the rail 102. From the phase difference, the position on the rail 102 is then calculated by the determination unit, which is located in the electronic device 103 or in the control device 106. The advantage here is that no further line is necessary and the rail 102 can thus be made narrower.
    In a variant of this embodiment in Fig. 8b, two frequency lines 805, 806 are additionally applied to the rail 102, which are then occupied by two frequencies 801, 802. The frequencies and their phase difference may then be performed by the electronic device 103 at two locations 803, 804 of the frequency lines 805, 805 along a cross-section of the rail 102. The position on the rail 102 is then calculated by the electronic device 103 or in front of the control device 106 from the phase difference. The position determination can thus take place independently of the data and supply lines 601, 602, 603.
    In Fig. 9, another embodiment of the rail 102 is shown. Here, a resistance path 901 is used 902 connected to one of the supply lines 602 at one end of the rail 102. The resistance now increases continuously with the distance from the end of the rail 102 at which the resistance path 901 is connected to the supply line 602 902. The resistance can be detected by a corresponding measuring device from the electronic device 103, and from this the distance to the end of the rail 102 and thus the position of the electronic device 103 on the rail 102 can be calculated. Optionally, it is also possible to use two resistor tracks with the same or different resistances, which are connected at different ends of the rail 102 to different supply lines 602, 603 for increasing the accuracy.
