Control module for controlling a lamp, in particular a street lamp, and lamp network
The present invention relates to a control module for controlling a lamp, in particular a lamp made in the form of a lamp, and a lamp array. According to the state of the art, it is known that lamp arrays are equipped with an increasingly intelligent control. For example, remote management systems are known for the management of lamp arrays in which a segment controller connected to a management console on a PC controls a certain number of lamps through their control module. The segment controller that is too large to fit into a lamp should be placed so that the lamps to be controlled can communicate with a short distance communication module through it. Segment controller failure results in loss of maneuverability of the lamp array.
It is also known how to equip all the lamp control modules of a network to be controlled with a long distance communication module, for example based on GSM technology, enabling them to communicate with a central server. Given the large number of actively integrated control modules in a long distance communication network and / or operator, noticeable communication costs are generated for this network.
In addition, the commissioning of known systems is expensive because the allocation in particular controllers supporting GPS technology to a lamp must be done manually. Finally, because of the large number of lamps that can be excited by a segment controller, the latency in the network is comparatively high.
The object of the present invention is to provide a control module for the management of a lamp network which is easier to put into service, which guarantees a higher operating safety (of the network) and whose management costs by elsewhere cheaper.
This object is achieved by an object according to claim 1, an object according to claim 12 and an object according to claim 14. The invention provides a control module for controlling a lamp, particularly a lamp in the form of a street lamp, a long distance communication module, a short distance communication module, a geolocation module, a controller, preferably at least one sensor and a control output for exciting a driver of the lamp, a server that can be joined via the long distance communication module, and the control module being adapted to transmit to the server information of the environment, the lamp and / or the control module.
The information of the environment can here be information recorded by sensors of the environment. It can be here for example sensors for the identification or recognition of objects in approach, p. ex. of vehicles. However, it is here geographical coordinates detected via the geolocation module. In order to determine a position of the control module, use is made in particular of modules based on GPS, GLONASS, Galileo, Bei-Dou or other position determination systems, in particular by satellite. At the same time, a module is not necessarily an independent unit. It may be more of a unit of the control module defined for example on the same plate as that on which the controller is defined. The control module can for example be used as a separate building element or as an integral part of a lamp.
Thanks to the communication of geographical coordinates as well as any other information specific to the control module and to the lamp, a remote management system server is able to create an accurate representation of the installed control modules and to assign groups and distribute control modules installed based on predefined or predefined control strategies by the server.
Within the distributed groups, communication is then via the short distance communication module to a group controller which is the only one in the group to be able to exchange data with the server via its long distance communication module. The long distance communication module can be based on different network techniques. This may be, for example, mobile data networks, IP networks or p. ex. long distance peer-to-peer networks. If replacement is required, another group controller supporting communication with the server in case of failure of the first group controller may be determined by the server. Group control modules may be aware of the replacement group controller either prophylactically or by reassignment in the event of a failure.
In particular, it is advantageous for the recording of lamp-specific information that a control module according to the invention has in particular a near-field communication module comprising a near-field sensor. This is preferably an RFID reader that can read the information stored in the lamp. This information can then also be transmitted to the server via the group controller. The installation of the control module is thus much faster than when an editor must record and transmit any specific information to the lamp. As a result, the margin of error is much smaller.
To be able to read an information medium placed in the lamp head in the case of arrangement of the control module essentially outside, the latter can be designed in two parts. A first part must be placed outside a lamp head while a second part must be arranged inside. Depending on the formation of the control module, the part on the outside may be exclusively an antenna part serving for short and long distance communication. Alternatively, a small number of elements of the control module, for example the described RFID reader, may also be simply disposed within the body of the lamp.
In order to be able to guarantee an internal communication to the group without any problem, the short distance communication modules may be capable of multiplexing and thus in particular be designed to communicate on different frequencies, in particular via a single antenna. I! for example, it is possible to separate, as a function of frequency, a scan of the available environment for known standards such as the ZigBee standard from a usual communication of the control module with the group controller so that adjacent groups have no influence on each other at different communication states. The installation of a control module according to the invention can also be performed more quickly when the control module is equipped at the factory with connection information for an operator of a mobile data network (roaming access) acting especially at the international level. Directly after the voltage load and if necessary after a first installation of a control module, it is already possible to transmit information to the server. It can then offer, for example, the local identifiers of a local mobile data network, which can be done for example by communicating a firmware to an electronic SIM card of the control module. The at least one sensor may preferably be a brightness sensor so that at least one operation of the lamp available depending on the brightness is possible in a fail-safe state (without contact). with a server. For the detection of seismic waves in particular, it may also be an acceleration sensor and / or a seismometer in the case of the sensor, a sufficient analysis and determination of the seismic waves being made precisely possible by a network of sensors and the detection throughout the network of the events of jolts recorded by acceleration sensors yet potentially inaccurate.
In the context of the invention, the control modules must be equipped with a large number of sensors. By way of example, it is also possible to use, in addition to a brightness sensor, an acceleration sensor for detecting shake events and / or an infrared sensor for detecting objects on approach, e.g. ex. vehicles or pedestrians.
In the case of a seismometer, the sensor may also be placed in the lamp at a location remote from the remaining control module. This can be here for example the arrangement in a foot of a lamppost.
The mission defined in the introduction is also fulfilled by a lamp, in particular a street lamp, with the advantages described above or hereafter, the lamps being equipped with a corresponding control module.
Preferably, an RFID transponder should be placed with the lamp-specific data in or on the lamp head to record lamp-specific data. This transponder can be read by an RFID reader via a control module. Instead of an RFID transponder, it can also be another data medium that can be read preferably without contact.
A network developed with control modules described above or hereafter comprises a large number of lamps equipped with a control module and a server, in which the network comprises one or more groups preferably ranging up to 200 lamps, in particular up to 50 lamps, in which each lamp comprises a control module as described above or below, and in which each group has a control module defined as a group controller and authorized to communicate with the server via the long distance communication module while the remaining control modules are indirectly designed to communicate with the server through the group controller and with each other as well as with the group controller to communicate via the short distance communication module.
For network mounting, the control modules of a server are distributed in one or more groups of control modules, this distribution being done on the basis of the information of control module, environment and / or lamp set. provision by the control modules.
In addition to the geographic coordinates, the environment information also relates to the information on the neighboring control modules in the short-distance network (eg the quality of the connection and / or other RF characteristics and / or neighbor tables). ) and / or environment-specific information (eg ambient brightness). In the case of lamp information, it may be information about the lighting sources used, their driver and / or other details of the assigned lamp, eg. ex. the current light intensity or gradation. In the case of the information of the control module, it is in particular information relating to the clear identification of the control module as its IP address or another U! D (Unique IDentifier).
According to the invention, one of the control modules of each group and / or only the group in the case of a single group is selected on the server to serve as a group controller. The latter allows the other control modules of the corresponding group to communicate using their short distance communication modules. In other words, the internal communication of the group is done using the corresponding short distance communication module. In the group, the control modules of a group form a short distance network, preferably in the form of a mesh network, through the corresponding short distance communication modules. In the normal operating state of the network, only the group controller transmits through the long distance communication module to the server its own information, as well as information about the environment, lighting, and / or control module received by the other control modules via the short distance communication module. By normal operating mode is understood here a regular operation of the network in which control modules of the network are respectively assigned to a group and perform their actual task: the control of the lamp. The information is always transmitted as indicated above and hereinafter by transmitting the corresponding data on the basis of a given communication protocol.
In use, such a network structure is more secure against failures than previous network systems. Due to the redundant structure of the corresponding control modules in a group, a new group controller can be determined without problem on the server in the event of a failure of a group controller. Once the new group controller is known within a group, i.e. at the level of the short-distance network (PAN = Personal Area Network), the connection of the other control modules does not exist. have not been defined as a group controller is done precisely by this one. A system command on the server as well as a system monitoring on the server can therefore always be kept in this way. Since there is only one active control module (group controller) per group, the costs are significantly lower than when all the control modules communicate separately with the server via their long distance module. corresponding.
The structure of the network internal to the group as a mesh network makes the operational safety and / or the communication at the PAN level also more secure against failures.
Since "in which" is used above or hereinafter to explain process steps, this does not necessarily imply the existence of simultaneity of the related process steps. this is an obligation).
The commissioning of the network is also simplified when the network automatically detects geographical information, especially during the first commissioning, preferably generated by the first power up, and therefore by an automatic procedure after the excitation of the network. control module In the case of geographical information, this is location data, ie coordinates as well as an exact time stamp The geographic information is recorded by the geographic coordinate module. or successively, a connection is established with the network operator via the long distance communication module, preferably a communication line provider, for example a provider of telephone lines and data lines. Communication can in particular be done in roaming conditions so that it is not necessary to predefine in the factory that the m the same communication information, regardless of where the different control modules will later be installed. On the control module side, the controller and / or the long distance communication module thus has uniform access data.
After the connection with the network operator, the geographic information can then be transmitted to the server together with the information specific to the control module and / or lamps. Automated data backup on the server in a corresponding database makes it easy to install streetlights. For reduced communication costs, operator access data specific to a locally available long distance network may be transmitted to a control module after transmission of its information.
In particular, operators can make access data available to control modules with an electronic SIM card via a firmware. In this case, the new firmware is read on the controller and / or the long distance communication module so that commissioning of the control module is possible at low costs under local conditions. At the same time, flexible communication and installation of the corresponding control modules can be achieved by preparing the server-side firmware without requiring equipment other than the factory modules.
By server, it is not necessary to understand hardware separate means, but it can also be a separation simply related to the project in a remote management program. It can also be virtual servers on the same hardware or in a cloud.
For trouble-free operation after the first request, the project server can preferably obtain information from the registration server about the devices in service.
In order to reduce costs, an interface makes it possible to communicate from the server to the long-distance network operator and / or the network operator information relating to the control module to be activated, to suspend and / or to deactivate with respect to their long distance communications. On the operator side, this ensures that only a small number of control modules (one control module per group) is activated. The other control modules can communicate with the server only via the communication route in the mesh network and then with the server via the group controller. A suspension, in particular of an electronic SIM card, has the consequence that it can be activated in the short term in case of doubt, for example in case of failure of the group controller. The network compensates for the malfunction of a communication route, preferably automatically and thus only with a minimum delay, and establishes a new one. The new communication can be initiated by the control module via a corresponding request from the server or via a request based on time and the attempt to access the operator's network.
Information that other control modules communicate to the normal operating state with the new group controller can then be transmitted by the server to these other control modules.
To signal to the operator staff the successful commissioning, for example the successful integration of a control module into the group network or the successful contact with a server, when installing a new lamp, a new control module and / or after maintenance operations on the corresponding lamp, the control module, after reaching the desired state, can operate the lamp with different brightnesses over a predefined or definable period of time.
Preferably, at least one of the control modules receives a group of parameters for operating the lamp after the first installation and / or a new installation. This can be, for example, variation curves.
The management of this lamp network is also better when the control modules of a group can receive software updates through software transferred from the server to the group controller. This makes it possible to obtain and / or where appropriate to activate, for example, new functions of the lamp.
As a variant, a server control module can directly obtain a new controller software, in particular a firmware, bypassing the group controller. However, the corresponding control module at the operator must first be actively switched again for this purpose.
In order to easily record the information of the short distance network environment and the communication in the short distance network for the normal management (communication with the server), it may be advantageous for the corresponding communication to take place in the network. short distance network on different frequency bands of the same network. The same antennas can preferably be used for this purpose (multiplexing mode).

Fig. 2 another object according to the invention,

Various technical features of the exemplary embodiments described hereinafter can also be combined in association with embodiments described above as well as with the features of the independent claims and any other claims relating to the objects according to the invention. Insofar as this is relevant, elements with the same functionality have identical reference numbers.
In accordance with the method according to the invention, a large number of control modules 1 are respectively assigned to a group controller 2 according to FIG. 1. On a hardware level, the group controller 2 is constructed in the same manner as the control modules 2. However, only the corresponding group controller 2 is able to interact with a server 4 over a long distance connection 3. Typically, this is access to a local mobile data network provider through which the server remains available through IP-WAN. The communication between the server and the group controllers can for example be done via a conventional internet protocol (TCP / IP).
Within a group 7, the control modules communicate with each other via short-distance connections 6, this is preferably a communication on the basis of a mesh network based on the IEEE802 standard. .15.4, p. ex. ZigBee.
The corresponding groups 7 of the control modules 1, 2 can not generally be seen on the entire group and can thus interfere with each other. It may, however, be provided for group-wide communications that neighboring control modules may share and / or exchange or transfer sensor data across the group through a connection with each other or with each other. 8 at short distance. This can result in actions such as increasing light intensity. Alternatively, this communication can also be done by controllers 2 corresponding groups that can be seen on the Internet by their IP address. The information on which command module to communicate with which command module and / or the way this module must communicate is defined by the server and can be sent to the entire group, in particular by a unit. multiplexing each control module, for example in the case of short distance communication.
In addition to connecting one or more groups 7 of control modules 1, 2 forming a PAN, a server for managing a network according to the invention can also control a network according to the state of the art with a segment controller 8 (Figure 2). The latter manages a series of 9 lamp controllers. The connection of the segment controller 8 is via an interface 11 allowing data exchange with the server 4, In addition to a connection of several groups 7 via another interface 12 if necessary, the server 4 can exploit a data exchange with a server. long distance network operator 14 via yet another interface (API) 13).
A database 16 interacting with different service modules (clients) generally operates on the actual server. A graphical user interface allows a user to access the server and / or its programs to operate and control the lamp groups.
Figure 3 briefly describes the progress of the construction of a network of streetlights. After the installation of a certain number of control modules on the street lamps, their environments are scanned in a first phase 20 launched by the server and / or starting automatically and the corresponding environmental information as well as any other information. specific to the control module and / or lamps are transmitted to the server. This can be done either directly under roaming conditions with a first operator or, if necessary, with another predefined local network operator after a first request from the corresponding control modules. After the transfer of the environmental information and other information from the corresponding control modules of the street lamps, the control modules are determined and allocated in groups as well as the group controller. At the PAN level, the network can be constituted for example dynamically on the basis of the standards used. The system proceeds to a normal operation mode 22 once the corresponding group controllers have transmitted to the server a data signal on the successful establishment of internal group communication. Provided that another number of new predefined command modules on the server have been installed, the process can again be performed in accordance with the feedback loop 23,
According to another exemplary embodiment of the invention according to FIG. 4, a plurality of lamps is arranged along a road 24 with corresponding control modules 23 and 23 '. The lamps are part of a group of lamps and / or control modules A predefined by the server. Group A is just as identifiable as group B with dotted lines 26 and / or 27. Lamps with corresponding control modules 28 and / or 28 'which mark a transverse street opening into the street 24 are part of the group B. Circles 31 and 32 internal black characterize a lamp with an active control module, a controller groups. The sensors S1 and S2 are assigned to the corresponding module 23 and / or 28. Radar sensors, infrared sensors (in particular passive infrared sensors) or even inductive loops in the street 24 and / or 29 come into play as sensors. They detect an object in approach, p. ex. a vehicle, then the control modules adapt the light of the corresponding lampposts of the group to the situation either internally to the group or all groups.
An object approaching, p. ex. a car, for example is detected by the control module 23 of the street lamp with the sensor S1, the information is distributed in the group or in part of the group and the light of the group A is increased by the modules 23 and 23 'of ordered. Likewise, this information or the information on the approaching car is transmitted to the group group controller 28 'via group controller 23'. Moreover, the brightness in group B is also adapted for the lamps of the relevant control modules 28 and / or 28 ', that is to say selected on the server. As a variant, the control module 23 equipped with the sensor S1 can also communicate directly with the group 'group' controller 28 'or with the other control module 28 assigned to it, the information being distributed in the network and the corresponding reaction. being in group B.
The server can proceed to the assignment to a first group of the various control modules and therefore corresponding street lights which must be powered by information from a sensor of a neighboring group and via which the information is transmitted on all the groups. Corresponding input masks are available for this purpose, especially on the server.
A control module according to the invention with which the method described hereinafter is to be converted may preferably be employed as a separate unit on a lamp head, for example a lamp post (see Fig. 7). The main parts of a control module that can be used externally are disclosed in more detail in FIG. 5. In the exploded view shown here, the control module comprises an upper housing portion 33 and a lower housing portion 34. . The lower housing portion must be attached by a gasket 35 to a pedestal to be placed on the upper face of the lamp. The connection to the base is provided by contacts 37 to turn like bayonets. The contacts 37 are fixed on the one hand in the casing 34 and on the other hand support a central platinum unit 38. A controller 39, a short long distance communication module and an acceleration sensor unit 41 are in use. placed on it to detect waves, in particular seismic waves.
An RFID reader that can be placed in a body-side base of the lamp to record lamp-specific data of an RFID transponder in the near field is not shown. The illustration according to Figure 6 shows a road system with a plurality of streets 42 of a length of several hundred meters. These streets are marked by a large number of lampposts 43 with the corresponding control modules. The control modules are respectively provided with sensors for detecting seismic waves. It can be here on the one hand be simple acceleration sensors. Alternatively, more expensive seismometers can also be used by being integrated into the lamp post. The data coming out of the acceleration sensors, preferably integrated in the control module directly into the housing, can be transmitted to the server by the group controller and its long distance communication module, even in the case of relatively inaccurate sensors. Because of the large number of signals that it sends, seismic waves can thus be detected and analyzed on the server with a good spatial and temporal resolution because of the geographical coordinates to be transmitted by the control modules as well as by the group controller. . As a result, even in the case of poor resolution of P and / or S waves, the seismic event can be represented comparatively accurately. Information about the epicenter of the earthquake can also be extracted from this information. This can be done either on the network server or on a special server assigned to the center of the earthquake. Therefore, it can also result in a tsunami and / or earthquake alert by the excitation of the lamps, for example by sending light signals previously brought to the attention of the population. For example, these may be light signals of alternating light intensity propagating in the form of waves along the road. The integration of a floor lamp according to FIG. 7 into the ground and the fixed arrangement and the connection thereof to the ground by means of, for example, a layer of lean concrete 44, a foundation tube 45 as well as that a dense filling material 46 allows the acceleration sensors arranged in or on the lamp head 48 in the control module to record well by the mast 49 the seismic waves propagating in the ground or along its surface . Alternatively or in addition, a fine-resolution seismometer 52 connected to the control module 2 by a data line (not shown) can also be placed in the foot of the mast 49. A major advantage of the system is the evaluation of a a large number of sensors distributed over the entire surface that can take place almost simultaneously and an analysis for the detection of the seismic waves represented in dashed lines in FIG. 6. An information system making it possible to simultaneously inform a large number of users of the road is simultaneously possible.
