[0008] The control system described below includes a first communication system S10, a second communication system S20, and a processing device (gateway device 40). The first communication system S10 is a system in which a lighting device 50 and a first control device (lighting control device 30) that controls the lighting device 50 are communicatively connected. The second communication system S20 is a system in which a sensor 60 attached to the lighting device 50 and a second control device (gateway device 40) that controls the sensor 60 and is capable of communicating with the first control device are communicatively connected. The processing device generates linking information that links sensor information related to the sensor 60 with lighting device information related to the lighting device 50, and performs processing based on the linking information.

[0009] The processing device described below is provided in at least one of the first control device and the second control device.

[0010] The processing device described below is a higher-level device that can communicate with the first control device and the second control device.

[0011] The lighting device information described below includes at least location information indicating the installation location of the lighting device 50.

[0012] The sensor 60 described below is detachably attached to the lighting device 50. The processing device performs processing to identify the installation position of the sensor 60 based on the linking information in which lighting device information including position information is linked.

[0013] The lighting device 50 described below is communicatively connected to the sensor 60, thereby acquiring sensor information from the sensor 60 and transmitting the sensor information to the processing device via the first control device. The processing device generates linking information that links the sensor information received from the lighting device 50 via the first control device with the lighting device information of the lighting device 50.

[0014] A lighting device 50 described below supplies power to a sensor 60 attached to itself. The sensor 60 transmits sensor information to the lighting device 50 that supplies the power.

[0015] The sensor 60 described below is communicatively connected to the lighting device 50, thereby acquiring lighting device information from the lighting device 50 and transmitting the lighting device information to the processing device via the second control device. The processing device generates linking information that links the lighting device information received from the sensor 60 via the second control device with the sensor information of the sensor 60.

[0016] The lighting device 50 described below is capable of communicating with both the sensor 60 and the second control device, and transmits sensor information received from the sensor 60 and its own lighting device information to the processing device via the second control device. The processing device generates linking information that links the sensor information received from the second control device with the lighting device information.

[0017] The lighting device 50 described below is an elongated lighting device 50 in which a communication unit 51 that communicates with a sensor 60 is disposed at an end in the longitudinal direction. The sensor 60 is attached at a position separated from the communication unit 51 in the longitudinal direction, and the longitudinal direction is the direction of communication with the communication unit 51. The attachment direction of the sensor 60 is perpendicular to the communication direction.

[0018] The processing device described below acquires sensor detection information from the sensor 60, and controls the lighting device 50 identified by the linking information based on the sensor detection information.

[0019] Hereinafter, a control system according to an embodiment will be described with reference to the drawings. The same components in the embodiments are denoted by the same reference numerals, and duplicated descriptions will be omitted.

[0020] First, an overview of a control system S according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of a control system S according to an embodiment. The control system S according to an embodiment is a system that controls functional devices (lighting devices 50 and sensors 60) installed in a predetermined area such as the interior of a predetermined building or outdoors.

[0021] As shown in FIG. 1, the control system S includes a first server 10, a second server 20, a first communication system S10, and a second communication system S20.

[0022] The first server 10 is a higher-level device communicatively connected to the first communication system S10. The first server 10 is, for example, a cloud computing system. The first server 10 acquires information from the first communication system S10 and outputs an execution instruction to control the lighting device 50 of the first communication system S10. Specifically, the first server 10 outputs an execution instruction to the lighting control device 30 of the first communication system S10 to instruct the lighting device 50 to execute a lighting function. Note that the first server 10 may acquire information from the second communication system S20 via the first communication system S10 and control the lighting device 50 of the first communication system S10 or the sensor 60 of the second communication system S20.

[0023] The second server 20 is a higher-level device communicatively connected to the second communication system S20. The second server 20 is, for example, a cloud computing system. The second server 20 acquires information from the second communication system S20 and outputs an execution instruction to control the sensor 60 of the second communication system S20. Specifically, the second server 20 outputs an execution instruction to the gateway device 40 of the second communication system S20 to instruct the sensor 60 to execute a detection function. The second server 20 may acquire information from the first communication system S10 via the second communication system S20 and control the lighting device 50 of the first communication system S10 or the sensor 60 of the second communication system S20. Although FIG. 1 illustrates a configuration separated into the first server 10 and the second server 20, a single server including the first server 10 and the second server 20 may be communicatively connected to both the first communication system S10 and the second communication system S20.

[0024] The first communication system S10 is a system in which a lighting control device 30 is communicatively connected to a plurality of lighting devices 50. The lighting control device 30 and the lighting devices 50 are communicatively connected, for example, via a transmission path conforming to the DALI (Digital Addressable Lighting Interface) (registered trademark) standard (first communication standard). The lighting control device 30 and the first server 10 are communicatively connected via a communication network such as the Internet.

[0025] The lighting control device 30 is communicably connected to a plurality of lighting devices 50, and performs lighting functions by controlling the lighting devices 50 in accordance with execution instructions from the first server 10. The lighting control device 30 can also control the lighting devices 50 in accordance with control instructions from the gateway device 40. The lighting control device 30 is a so-called lighting control panel. The lighting control device 30 is an example of a first control device.

[0026] The lighting device 50 is a functional device having a lighting function. The lighting device 50 performs the lighting function under the control of the lighting control device 30. The lighting device 50 is, for example, a long lighting device (so-called lighting bar) installed on the ceiling inside a building.

[0027] The second communication system S20 is a system in which a gateway device 40 and a plurality of sensors 60 are communicatively connected. The gateway device 40 and the sensors 60 are communicatively connected by wire or wirelessly via a communication network such as the Internet (an example of a second communication standard). The gateway device 40 and the sensors 60 may also be connected by a short-range wireless communication standard such as Bluetooth (registered trademark) (an example of a second communication standard).

[0028] The gateway device 40 is communicatively connected to a plurality of sensors 60, and executes a sensor function by controlling the sensors 60 in accordance with execution instructions from the second server 20. The gateway device 40 collects detection information (sensor detection information) detected by the sensor function and transmits it to the second server 20. The gateway device 40 may transmit the detection information to the first server 10 via the lighting control device 30. The gateway device 40 is an example of a second control device. The gateway device 40 also functions as a processing device that generates association information, which will be described later, and performs processing based on the association information. Although the present disclosure illustrates a case in which the processing device is the gateway device 40, the processing device may be the first server 10, the second server 20, or the lighting control device 30.

[0029] The sensor 60 is a functional device having a sensor function for detecting the surrounding conditions. The sensor 60 executes the sensor function under the control of the gateway device 40. The sensor 60 is, for example, an infrared sensor, a human presence sensor, a camera, a carbon dioxide sensor, a temperature sensor, an earthquake sensor, a smoke sensor, etc. The sensor 60 is installed in the area (inside the building) where the lighting device 50 is installed. Specifically, the sensor 60 is attached directly to the lighting device 50 or installed in the same space (the same room) as the area where the lighting device 50 is installed.

[0030] The first communication system S10 and the second communication system S20 are communicatively connected via a communication network such as the Internet. Specifically, the lighting control device 30 and the gateway device 40 are communicatively connected via the communication network in a wired or wireless manner.

[0031] In such a configuration, the control system S according to the present disclosure is configured to be able to expand the functions of the functional devices. For example, the control system S can add a new sensor function of a sensor 60 by adding a new sensor 60 connected to the gateway device 40. Specifically, in the control system S, the first server 10 and the second server 20 pre-register information (such as identification information and sensor type) of the sensor 60 that can be added, and when a new sensor 60 is communicatively connected to the gateway device 40, the first server 10 and the second server 20 add and expand the sensor function of the new sensor 60 to the targets of execution instructions. In other words, when a new sensor 60 is communicatively connected to the gateway device 40, the first server 10 and the second server 20 instruct the execution of the sensor function of the new sensor 60, thereby enabling detection processing by the new sensor 60.

[0032] Furthermore, in the control system S, the gateway device 40 generates association information that associates the sensor 60 with the lighting device 50 to which the sensor 60 is attached, and performs various processes based on the association information. For example, the gateway device 40 stores the association information, and when detection information is acquired from the sensor 60, the gateway device 40 controls the lighting device 50 identified by the association information (the lighting device 50 to which the sensor 60 is attached) based on the detection information. Furthermore, in the control system S, the gateway device 40 transmits the generated association information to the first server 10 and the second server 20.

[0033] When a new sensor 60 is communicatively connected to the gateway device 40, the first server 10 or the second server 20 can add and expand the lighting function associated with the information of the sensor 60 to the targets of execution instructions based on the association information. In other words, when a new sensor 60 is communicatively connected to the gateway device 40, the first server 10 or the second server 20 can output an execution instruction for the lighting function using detection information detected by the new sensor 60. In other words, the first server 10 or the second server 20 expands the functional content of another functional device (lighting device 50) that is already communicatively connected, based on the function of the newly connected functional device (sensor 60). As an example of this, when a camera is newly added as the sensor 60, the first server 10 or the second server 20 can add a lighting function that identifies a suspicious person from a camera image and turns on the lighting device 50 at the location where the suspicious person is located.

[0034] In this way, in the control system S of the present disclosure, the gateway device 40, which is a processing device, generates information linking the sensor 60 and the lighting device 50, so that the position of the sensor 60 can be easily identified from the position of the lighting device 50 to which the sensor 60 is attached. This eliminates the need for an operator to set the position of the sensor 60 when the sensor 60 is later attached to the lighting device 50, thereby reducing the burden on the operator.

[0035] In the above, an example has been given in which the lighting function is expanded by adding a new sensor function, but for example, the first server 10 and the second server 20 may be connected to an external server for communication and may acquire earthquake early warning information, etc. from the external server to expand the lighting function.

[0036] Furthermore, when transmitting detection information transmitted from the sensor 60 to the first server 10 or the second server 20, if the identification information of the sensor 60 included in the detection information does not satisfy a predetermined condition, the gateway device 40 may not transmit the detection information to the first server 10 or the second server 20. For example, the gateway device 40 stores the identification information of the sensor 60 obtained when the sensor 60 is connected for communication, and if the identification information included in the detection information matches the stored identification information, the gateway device 40 transmits the detection information to the first server 10 or the second server 20. On the other hand, if the identification information included in the detection information does not match the stored identification information, the gateway device 40 prohibits transmission of the detection information to the first server 10 or the second server 20. This makes it possible to avoid erroneous control of the lighting device 50 caused by transmitting detection information of an unauthorized sensor 60 not registered in the first server 10 or the second server 20 to the first server 10 or the second server 20.

[0037] Next, the gateway device 40, which is a processing device, will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of the functional configuration of the gateway device 40 according to the embodiment. The gateway device 40 includes a communication unit 41, a control unit 42, and a storage unit 43. The gateway device 40 is also connected to the second server 20, the lighting control device 30, and the sensor 60.

[0038] The communication unit 41 is realized by, for example, a predetermined communication circuit etc. For example, the communication unit 41 relays communication between the second server 20, the lighting control device 30, and the sensor 60 via a network such as Ethernet (registered trademark) or a LAN.

[0039] The storage unit 43 stores programs for implementing control by the control unit 12, linking information 131, function information 132, etc. The storage unit 13 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk.

[0040] 3 is a diagram showing an example of the association information 131. The association information 131 is information in which lighting device information, which is information related to the lighting device 50, is associated with sensor information related to the sensor 60. The association information 131 is generated by the control unit 12. As shown in FIG. 3, the association information 131 includes a "linking ID," "lighting device information," and "sensor information."

[0041] The "linking ID" is identification information that identifies each piece of linking information. The "lighting device information" is information related to the lighting device 50, and includes a "lighting ID" and "location information." The "lighting ID" is identification information that identifies the lighting device 50. The "location information" is information about the installation location of the lighting device 50. The "lighting device information" can be obtained, for example, from the lighting control device 30.

[0042] "Sensor information" is information related to the sensor 60 and includes a "sensor ID" and a "sensor type." The "sensor ID" is identification information that identifies the sensor 60. The "sensor type" is information that indicates the type of sensor 60, and is information that distinguishes between, for example, an infrared sensor, a human presence sensor, a camera, a carbon dioxide sensor, a temperature sensor, an earthquake sensor, a smoke sensor, etc. The "sensor information" is registered in advance by an administrator of the sensor 60, or is registered based on information sent from the sensor 60 when a new communication connection is established.

[0043] In the association information 131, the lighting device 50 and the sensor 60 associated with the same association ID have the same installation location. For example, when a sensor 60 is attached to a lighting device 50, the lighting device 50 and the sensor 60 are associated with the same association ID in the association information 131.

[0044] 3 is an example. For example, the association information 131 may be information in which only a lighting ID and a sensor ID are associated. In this case, the gateway device 40 identifies the position of the sensor 60 by acquiring location information of the lighting device 50 from another device. For example, when the gateway device 40 acquires detection information from the sensor 60, the gateway device 40 notifies the lighting control device 30 of the lighting ID associated with the sensor ID of the sensor, and acquires the location information of the lighting device 50 (i.e., the location information of the sensor 60) from the lighting control device 30.

[0045] Fig. 4 is a diagram showing an example of the function information 132. The function information 132 is information indicating functions that can be executed in the control system S. Note that while Fig. 4 shows the function information 132 related to the lighting function, the function information 132 may further include function information related to the sensor function. The function information 132 is registered in advance by an administrator of the control system S.

[0046] As shown in FIG. 4, the function information 132 includes a "function ID," a "function content," a "lighting control content," and "required information." The "function ID" is identification information that identifies a lighting function. The "function content" is information that indicates the content of the lighting function. The "lighting control content" is information that indicates the content of the lighting control. The "required information" is information (or sensor 60) that is required to enable the lighting function.

[0047] For example, the lighting function "Earthquake Response" identified by the function ID "F1" is enabled when a communication connection is established with an external server that provides earthquake information and an earthquake sensor. In other words, the lighting function "Earthquake Response" identified by the function ID "F1" is added and expanded as a target of the execution instruction.

[0048] The control unit 42 is a computing device that executes various types of information processing, and may employ, for example, electronic circuits such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), or integrated circuits such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 42 has an internal memory for storing programs that define various processing procedures and control data, and executes various processes using these. The control unit 42 functions as an acquisition unit 121, a generation unit 122, and a processing unit 123 by running various programs.

[0049] The acquisition unit 121 acquires various types of information. The acquisition unit 121 acquires sensor information (identification information and sensor type) and lighting device information (identification information and position information). How the acquisition unit 121 acquires the sensor information and lighting device information will be described later with reference to FIGS. 5 to 7.

[0050] The acquisition unit 121 also acquires detection information detected by the sensor 60. The detection information includes the detection value of the sensor 60 and the sensor ID of the sensor 60.

[0051] The generation unit 122 generates association information 131 by linking the sensor information acquired by the acquisition unit 121 with the lighting device information, and stores the association information in the storage unit 13.

[0052] The processing unit 123 performs processing based on the linking information generated by the generation unit 122. For example, the processing unit 123 controls the lighting device 50 from the detection information of the sensor 60 based on the generated linking information. Specifically, the processing unit 123 identifies the position of the sensor 60 that obtained the detection information based on the linking information, i.e., the position of the lighting device 50 on which the sensor 60 is installed, and controls the identified lighting device 50.

[0053] Next, a method for acquiring sensor information and lighting device information for generating association information will be described with reference to Fig. 5 to Fig. 8. Fig. 5 to Fig. 8 are diagrams for explaining a method for acquiring sensor information and lighting device information. Fig. 5 to Fig. 8 show examples in which sensor information and lighting device information are acquired through different acquisition routes.

[0054] For example, in Fig. 5, first, the sensor 60 transmits sensor information to the lighting device 50 to which it is attached (step S1). For example, the sensor 60 and the lighting device 50 are capable of communicating with each other via short-range wireless communication, and the sensor information is transmitted via such short-range wireless communication. Specifically, the lighting device 50 supplies power to the sensor 60 attached to itself via contactless power supply. When the sensor 60 receives power from the lighting device 50, it is activated (powered on), and becomes able to transmit sensor information to the lighting device 50, which is the power supplier.

[0055] Next, the lighting device 50 transmits the acquired sensor information and its own lighting device information to the lighting control device 30 (step S2), and the lighting control device 30 transmits the acquired sensor information and lighting device information to the gateway device 40 (step S3). The gateway device 40 generates linking information that links the acquired sensor information and lighting device information.

[0056] In this way, in the control system S, the lighting device 50 can perform highly accurate linking of the linking information by transmitting the sensor information received from the sensor 60 and its own lighting device information to the gateway device 40 via the lighting control device 30. Furthermore, the sensor 60 can perform highly accurate linking of the linking information by transmitting the sensor information to the lighting device 50 that is the power supply source.

[0057] If the lighting control device 30 has previously stored the lighting device information of the lighting device 50, the lighting control device 30 may acquire the identification information and sensor information of the lighting device 50 in step S2, identify the lighting device information from the identification information, and transmit the identified lighting device information and sensor information in step S3.

[0058] Furthermore, if the gateway device 40 stores the sensor information in advance, the sensor 60 may transmit only the identification information of the sensor 60 in step S1, and the gateway device 40 may identify the sensor information from the identification information.

[0059] 6, first, the lighting device 50 transmits lighting device information to the attached sensor 60 (step S11). For example, the sensor 60 and the lighting device 50 are capable of communicating with each other via short-range wireless communication, and the lighting device information is transmitted via such short-range wireless communication.

[0060] Next, the sensor 60 transmits the acquired lighting device information and its own sensor information to the gateway device 40 (step S12). The gateway device 40 generates association information that associates the acquired sensor information and lighting device information.

[0061] In this way, in the control system S, the sensor 60 can perform highly accurate linking of the linking information by transmitting the lighting device information received from the lighting device 50 and its own sensor information to the gateway device 40. Note that if the processing device is a device other than the gateway device 40, for example, the second server 20, the sensor 60 transmits the lighting device information received from the lighting device 50 and its own sensor information to the second server 20 via the gateway device 40.

[0062] If the gateway device 40 has stored the sensor information in advance, the gateway device 40 may acquire the identification information of the sensor 60 and the lighting device information in step S12, and identify the sensor information from the identification information.

[0063] 7, it is assumed that the lighting device 50 and the gateway device 40 can communicate directly with each other via a communication network such as the Internet. In this case, the sensor 60 transmits sensor information to the lighting device 50 to which it is attached (step S21). For example, the sensor 60 and the lighting device 50 can communicate with each other via short-range wireless communication, and the sensor information is transmitted via such short-range wireless communication.

[0064] Next, the lighting device 50 transmits the acquired sensor information and its own lighting device information to the gateway device 40 (step S22). The gateway device 40 generates association information that associates the acquired sensor information and lighting device information.

[0065] In this way, in the control system S, the lighting device 50 can link the linking information with high accuracy by directly transmitting the sensor information received from the sensor 60 and its own lighting device information to the gateway device 40.

[0066] If the gateway device 40 has stored the sensor information in advance, the gateway device 40 may acquire the identification information of the sensor 60 and the lighting device information in step S22, and identify the sensor information from the identification information.

[0067] 8, lighting control device 30 is assumed to be supplying power to lighting device 50 (step S31). Specifically, lighting control device 30 supplies power to lighting device 50 to turn it on. At this time, lighting control device 30 stores the time when it was turned on. Then, when lighting device 50 is turned on, it supplies power to sensor 60 attached to lighting device 50 by contactless power supply or wired power supply (step S32).

[0068] Then, the sensor 60 is activated (powered on) by the power supply from the lighting device 50, and transmits its own sensor ID to the gateway device 40 (step S33). At this time, the gateway device 40 stores the time when the sensor ID is received.

[0069] Furthermore, lighting control device 30 transmits lighting device information of the lighting device 50 that has been powered on to gateway device 40 (step S34). At this time, lighting control device 30 also transmits information on the time when lighting device 50 was powered on to gateway device 40.

[0070] Then, the gateway device 40 generates association information that associates the received lighting device information with the sensor ID. Specifically, the gateway device 40 associates the lighting device information of the lighting device 50 and the sensor ID of the sensor 60 for which the difference between the power-on time of the lighting device 50 and the reception time from the sensor 60 is less than a threshold (ideally, the difference is almost zero).

[0071] In the configuration shown in FIG. 8, information transmission and reception between the lighting device 50 and the sensor 60 shown in FIGS. 5 to 7 is not performed, and linking can be performed using information on the power-on timing of the lighting device 50 and the reception timing from the sensor 60.

[0072] Note that, although FIG. 8 shows an example in which there is one pair of lighting device 50 and sensor 60, in the case of multiple pairs, the above-described steps S31 to S34 and the linking information generation process may be performed for each pair, or the linking information generation process may be performed after first completing all the processes of steps S31 to S33 (or may further include S34) for all the multiple pairs.

[0073] Next, the relationship between the communication direction and the installation method of the sensor 60 will be described with reference to Fig. 9. Fig. 9 is a diagram showing the relationship between the communication direction and the installation method of the sensor 60. In Fig. 9, the lighting device 50 is an elongated lighting device, a so-called lighting bar, as an example. In this case, the lighting device 50 is attached with the top surface in the longitudinal direction (upper side of the paper) to the ceiling.

[0074] As shown in Fig. 9, the lighting device 50 has a communication unit 51 that communicates with the sensor 60 disposed at one end in the longitudinal direction. The sensor 60 is attached to the other end in the longitudinal direction of the lighting device 50. Specifically, the sensor 60 is detachably attached to the top surface of the lighting device 50 by a fastener, a magnetic member, or the like (not shown). Although Fig. 9 shows an example in which the sensor 60 is disposed inside the lighting device 50, the sensor 60 may also be attached to the outside of the lighting device 50 (at the end opposite to the communication unit 51).

[0075] That is, the sensor 60 is attached to the top surface of the lighting device 50 (upward on the paper). As shown in Fig. 9, the sensor 60 and the communication unit 51 are attached to both ends of the lighting device 50 in the longitudinal direction, so the communication direction is the longitudinal direction (left-right direction on the paper). That is, the attachment direction of the sensor 60 is perpendicular to the communication direction.

[0076] In this way, by setting the mounting direction of the sensor 60 to a direction perpendicular to the communication direction, communication between the sensor 60 and the communication unit 51 can be performed in the internal space of the elongated lighting device 50. This makes it possible to avoid incorrect linking of the linking information due to erroneous communication with a lighting device 50 different from the lighting device 50 to which the sensor 60 is attached.

[0077] As described above, the control system S according to the embodiment includes a first communication system S10, a second communication system S20, and a processing device (gateway device 40). The first communication system S10 is a system in which a lighting device 50 and a first control device (lighting control device 30) that controls the lighting device 50 are communicatively connected. The second communication system S20 is a system in which a sensor 60 attached to the lighting device 50 and a second control device (gateway device 40) that controls the sensor 60 and is capable of communicating with the first control device are communicatively connected. The processing device generates linking information that links sensor information related to the sensor 60 with lighting device information related to the lighting device 50, and performs processing based on the linking information. As a result, the control system S according to the present disclosure can easily identify the position of the sensor 60 from the position of the lighting device 50 to which the sensor 60 is attached, based on the linking information. As a result, when the sensor 60 is later attached to the lighting device 50, an operator does not need to set the position of the sensor 60, thereby reducing the burden on the operator.

[0078] Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. This embodiment and its modifications are included within the scope and spirit of the invention, as well as the invention described in the claims and their equivalents. [Explanation of symbols]
