FIG. 2B is a sequence diagram showing the contents of the wireless communication unit setting process (step S200) shown in FIG. 2A.

(Initial state setting process)
In FIG. 2A, first, the lighting control system 1 performs an initial state setting process (step S100). For example, the control unit 242 of the setting device 24 acquires various setting data for wireless communication as the setting data TBL (step S121). In the setting data TBL, for example, data indicating the PANID used by the wireless communication unit 162 and the wireless channel is registered. On the other hand, after the lighting device with wireless dimming function 17 is installed (step S141), the power is turned on (power ON) (step S142). After the power is turned on, the control unit 172 of the lighting device with wireless dimming function 17 executes its own initialization processing, and sets the lighting state of the lighting unit 173 to a power-saving lighting state (step S142). Next, the control unit 172 determines whether or not to transit to the maintenance mode for performing various settings. For example, the determination of whether or not to transit to the maintenance mode may be performed on the condition that a predetermined signal is received before a predetermined time elapses after the power is turned on. After transitioning to the maintenance mode according to the determination result, the control unit 172 causes the illumination unit 173 to display that the state is transitioning to the maintenance mode (step S143). For example, the display of the maintenance mode may be performed by setting the lighting unit 173 to a predetermined lighting state.

(Wireless communication unit setting process)

In FIG. 2B, for example, the control unit 242 of the setting device 24 sends a setting instruction command (command information) to the lighting device with wireless dimming function 17 (step S221). The control unit 172 of the illumination device with wireless dimming function 17 receives the "setting instruction command (command information)" from the setting device 24, and transitions to the setting registration mode (step S241). The above “setting registration mode” is an operation mode for setting various variables of the wireless communication unit 171 and the illumination unit 173. The control unit 172 transmits individual identification information for identifying each illuminating device on a wireless signal (step S242). The control unit 242 receives the wireless signal from the lighting device with a wireless dimming function 17, and collects the received individual identification information (step S222). The control unit 242 creates an equipment list using the received individual identification information, and writes the created equipment list in the setting data TBL (step S223). The control unit 242 transmits the individual setting data of the wireless communication unit 171 on the wireless signal (step S224). For example, the individual setting data of the wireless communication unit 171 includes a wireless communication channel number (wireless ch) used for communication, network identification information (PANID), an encryption key used when encrypting or decrypting communication data, and a link control. It is address information (short address) to be used. The control unit 172 receives the individual setting data of the wireless communication unit 171 from the setter 24, writes the received individual setting data in the storage area of the control unit 172 (step S244), and displays the writing status (step S245). .. The setting data TBL can store information indicating the correspondence between individual identification information such as a MAC (Media Access Control) address and the DALI address.

  Next, the control unit 242 of the setting device 24 sends a setting instruction command (command information) to the wireless controller 16 (step S225). The control unit 161 of the wireless controller 16 receives the "setting instruction command (command information)" from the setter 24 and transitions to the setting registration mode (step S215). The “setting registration mode” in this case is an operation mode for setting various variables of the wireless communication unit 162. The control unit 161 transmits individual identification information for identifying its own device (for example, the wireless communication unit 162) on a wireless signal (step S216). The control unit 242 receives the wireless signal from the wireless controller 16 and collects the received individual identification information (step S226). The control unit 242 creates an equipment list using the received individual identification information, and writes the created equipment list in the setting data TBL (step S227). The control unit 242 transmits the individual setting data of the wireless communication unit 162 including various setting data for wireless communication and the setting information of the lighting device on the wireless signal (step S228).

  The control unit 161 of the wireless controller 16 receives various setting data for wireless communication and the setting information of the lighting device, and writes the received individual setting data as setting data TBL in the storage area of the control unit 161 (step S218). ). FIG. 9 shows an example of individual setting data (setting data TBL) of the wireless communication unit 162. As shown in FIG. 9, the setting data TBL includes a wireless parameter, a DALI parameter, and a parameter other than the DALI parameter. The wireless parameters include a wireless communication channel number (wireless ch) used for communication, network identification information (PANID), an encryption key used when encrypting or decrypting communication data, address information used for link control (short address), etc. including. However, the encryption key may be omitted. The DALI parameter includes a value when starting the dimming level, a maximum value, a minimum value, an abnormal value, information for setting a set of a plurality of parameters as a scene, information indicating a group to be collectively controlled, and the like. The parameters other than the DALI parameter include the PWM frequency, the physical minimum level, the set value of the duty ratio at startup, and the like. When the wireless parameter is received, the control unit 161 of the wireless controller 16 sets various variables of the wireless communication unit 162 to predetermined values, for example. That is, for example, the control unit 161 sets the PANID and the wireless ch used by the wireless communication unit 162 (for example, passes those setting values to the driver of the wireless communication unit 162).

(Lighting control information setting process)
Subsequently, the lighting control system 1 performs a lighting control information setting process (step S300). For example, the wireless controller 16 receives command information for instructing the setting of the individual lighting information, and puts the command information for instructing the setting of the individual lighting information on the wireless signal to the lighting device with wireless dimming function 17. Send. For example, the individual lighting information includes data such as fade rate, fade time, and group number (step S311). When the control unit 172 of the lighting device with wireless dimming function 17 receives the instruction information for instructing the setting of the individual illumination information, the individual illumination information is written in the storage area of the control unit 172 (step S341). Through the above processing, the lighting control system 1 finishes each of the “initial state setting processing”, the “wireless communication unit setting processing”, and the “lighting control information setting processing”, and performs the lighting adjustment processing (step S400). The lighting adjustment processing adjusts the lighting state of the lighting unit 173 included in the wireless lighting control device 17 by transmitting and receiving a predetermined wireless signal between the wireless controller 16 and the wireless lighting control device 17. It is a process to do.

  Next, with reference to FIG. 3, a configuration of a protocol stack used in wireless communication between the wireless controller 16 and the wireless lighting control device 17 (or the external wireless unit 22) will be described. FIG. 3 is an explanatory diagram for explaining a configuration example of a protocol stack applied to wireless communication between the wireless controller 16 and the lighting device with a wireless dimming function 17 in the lighting control system 1 shown in FIG. 1. Is. As shown in FIG. 3, the wireless controller 16 and the lighting device with a wireless dimming function 17 use the wireless communication units 162 and 171 in accordance with a protocol stack including a physical layer 401, a MAC layer 402, and an application layer 403. To send and receive wireless signals. In the present embodiment, the physical layer 401 may be based on the protocol specified by IEEE802.15.4g PHY, and the MAC layer 402 may be based on the protocol specified by IEEE802.15.4 MAC. can do. Further, the application layer 403 can make the message transmitted and received between the wireless controller 16 and the wireless illuminating device with wireless dimming function 17 compliant with CoAP. That is, by executing a predetermined program according to the protocol of the application layer 403, the control unit 162 of the wireless controller 16 and the control unit 172 of the lighting device with a wireless dimming function 17 send and receive a CoAP-compliant message, Execute a program to perform processing based on the message contents. The control unit 161 of the wireless controller 16 generates a CoAP-compliant message or converts a DALI-compliant command into a CoAP-compliant message by executing a program according to the protocol of the application layer 403, for example. To do Further, the control unit 172 of the illumination device with a wireless dimming function 17 controls the illumination unit 173 (FIG. 1) based on the content of the received message conforming to CoAP, for example.

  For example, in the lighting control system 1 of the present embodiment, the wireless controller 16 and the lighting device with a wireless dimming function 17 each wireless communication unit according to the protocol stack 400 including the physical layer 401, the MAC layer 402, and the application layer 403. When transmitting and receiving a wireless signal using 162 and 171, the wireless controller 16 executes a predetermined program in accordance with the application layer 403 to display a message including the PANID and the short address of the lighting device with wireless dimming function 17. It is determined and transmitted to another predetermined program executed according to the application layer 403 in the lighting device with wireless dimming function 17.

  Next, with reference to FIG. 4 and FIG. 8, a configuration example of a message transmitted / received according to the application layer 403 between the wireless controller 16 and the lighting device with a wireless dimming function 17 or the external wireless unit 22 will be described. .. When the control unit 161 transmits a CoAP message indicating a command for controlling the illumination unit 173 to the control unit 172, the control unit 161 specifies the URI of the following format and the type of CoAP method, Further, the wireless communication unit 162 is instructed to transmit a wireless signal including a CoAP message by specifying parameters as necessary. FIG. 4 is an explanatory diagram showing a configuration example of the URI used in this embodiment.

  FIG. 4A shows a general format of the URI specified when transmitting the CoAP message in the present embodiment, and FIG. 4B shows one format of the resource <resource> shown in FIG. 4A. And FIG.4 (c) has shown the specific example of URI. In the present embodiment, “coap” representing the URI scheme defined in RFC3986 is placed at the beginning of the URI when transmitting the CoAP message. Next, PANID <panid> indicating the wireless address of the destination is placed after "coap" followed by the symbol ": //", and further short address <short address> is placed between the symbols ":". It <Panid> and <short address> are represented by hexadecimal numbers. The PANID <panid>, the symbol ":", and the short address <short address> are URI authorities defined in RFC3986, and the URI of this embodiment has at least PANID <panid> and <short address>. Contains. Furthermore, the resource name <resource> follows with the symbol “/” sandwiched. Then, the query parameter <query> follows with the symbol "?". In this embodiment, the resource name <resource> is, for example, a character string representing a predetermined command related to the control of the lighting unit 173 by the control unit 172 or the control of the lighting unit 231 by the control unit 222.

  The resource name <resource> has, for example, the format shown in FIG. That is, “levels” and “actual” shown in FIG. 4B are the “DIRECT ARC POWER CONTROL” command (= any dimming according to the fade time) of the commands for operating the dimming level defined by DALI. Command) or a “QUERY ACTUAL LEVEL” command (= command for inquiring the current dimming level). Which of the two commands is represented depends on the type of CoAP method specified in the CoAP message. Further, in <channel>, for example, when the wireless communication unit 171 or the wireless communication unit 221 has a plurality of output channels, a value designating a channel number is set. For example, when the number of output channels is 1, set <channel> = <0>.

  There are four types of CoAP methods, GET, PUT, POST, and DELETE. GET is a method for acquiring information corresponding to the resource identified by the URI. PUT is a method for requesting to update or create the resource identified by the URI with the data included in the message. POST is a method for requesting processing of data included in a message. Then, DELETE is a method for requesting deletion of the resource identified by the URI.

  For example, when the CoAP method is “PUT” and the resource name <resource> is “/ levels / <channel> / actual” shown in FIG. 4B, “DIRECT ARC” is displayed for <channel>. The execution of the "POWER CONTROL" command is instructed. In this case, data indicating the dimming level is enclosed in the CoAP message. On the other hand, when the CoAP method is “GET” and the resource name <resource> is “/ levels / <channel> / actual” shown in FIG. 4B, “QUERY ACTUAL” is given to <channel>. Execution of the "LEVEL" command is instructed. In this case, the CoAP message does not need to include the data indicating the parameter.

  In the specific example of the URI shown in FIG. 4C, assuming that the address of the wireless communication unit 171 is “0021: 1E94”, the wireless communication unit 171 having the PANID of 0x0021 and the short address of 0x1E94 is connected. This is information for instructing the control unit 172 to execute the “DIRECT ARC POWER CONTROL” command or the “QUERY ACTUAL LEVEL” command represented by “/ levels / 0 / actual”.

  Note that the resource names described with reference to FIG. 4 are merely examples, and a plurality of other resource names can be prepared in association with other DALI commands.

  The format of the CoAP message is composed of fields 51 to 59, as shown in FIG. The 2-bit field 51 represents the version number of CoAP. The 2-bit field 52 represents the type of message. It indicates whether the message is Configurable (a message requesting a response), Non-Conformable (a message not requesting a response), Acknowledgement (a positive message), or Reset (a message requesting reset).

  The 4-bit field 53 represents the token length. The token is a consecutive number for matching the request message and the response message, and can be set to a length of 0 to 8 bytes. The 8-bit field 54 represents the code of the message. The code of the message is divided into 3-bit data representing the class and 5-bit data representing the details. The class indicates that the message is a request, that the message is a successful response, that the message is a client error response, and that the message is a server error response. There are things. Further, in detail, data indicating whether the CoAP method is GET, PUT, POST, or DELETE, data indicating the content of the response, and the like are defined. The 16-bit field 55 represents a message ID (identifier). The message ID is information that uniquely identifies a message, and is used to detect message duplication, to collate a request and a response, or a conformable and a non-comfortable.

  The above fields 51 to 55 are the header of the CoAP message. Fields 56 to 59 are optional fields. The field 56 stores the value of the token having the length designated by the field 53 indicating the token length. The field 57 stores 0 or a plurality of bytes of optional information. The option information includes data indicating a URI path (a character string shown as <resource> in FIG. 4) and the like.

  The field 59 stores information on an optional payload. The payload can store, for example, a dimming level instruction value. Fixed 1 byte (0xFF) data shown as field 58 in FIG. 8 is prepended to this field 59. In addition, not only ASCII characters but also arbitrary data can be stored in each field.

  Next, with reference to FIG. 5, an example of exchanging messages between the wireless controller 16 and the wireless lighting control device 17 shown in FIG. 1 will be described. In the example shown in FIG. 5, it is assumed that the wireless address of the wireless communication unit 171 is set to “0021: 1E94”.

  Now, it is assumed that a command to be issued to the lighting device with wireless dimming function 17 is generated in the control unit 161 (S11). For example, when the application program executed by the control unit 161 determines itself to issue a command based on time information, information acquired from the sensor 19, or the like, when the illumination controller 12 issues an instruction to issue a command, The command is issued when the command is issued from the terminal 13 in response to a user operation. In this example, it is assumed that the issue of a command for inquiring the current dimming level is determined to be issued to channel 0 of the wireless communication unit 171 in S11.

  The control unit 161 calculates the arrival time zone of the response message expected when the command is issued to the illumination device with wireless dimming function 17, and sets it as the determination time (S12). In S19, which will be described later, the control unit 161 determines that some problem may have occurred when the response message arrives before or after the determination time.

  Next, the control unit 161 instructs the wireless communication unit 162 to send a message in which the URI is “coap: // 0021: 1E94 / levels / 0 / actual” and the CoAP method is “GET”. Yes (S13). The wireless communication unit 162 has data indicating that the method is “GET” in the header of the CoAP message and data indicating that the URI path (that is, resource) is “/ levels / 0 / actual” in the field for storing the option. A CoAP message storing and is created. Then, the wireless communication unit 162 generates a wireless packet including the created CoAP message in the payload of the wireless packet, the wireless address set in the own device is the source address, and the wireless address of the wireless communication unit 171 is “0021: 1E94”. Is used as a destination address and a wireless packet is transmitted according to a predetermined wireless protocol using the set wireless channel (S14).

  Next, the wireless communication unit 171 receives the wireless packet addressed to itself, extracts the CoAP message, and indicates that the CoAP method is “GET” and the resource is “/ levels / 0 / actual”. The data is delivered to the control unit 172 (S15). Since the CoAP method is “GET” and the resource is “/ levels / 0 / actual”, the control unit 172 recognizes that the instructed command is the “QUERY ACTUAL LEVEL” command by DALI. .. Then, the control unit 172 instructs the wireless communication unit 171 to return a response message containing the value of the current dimming level of the illumination unit 173 (assumed to be “0x80”) as the execution result of the command ( S16).

  In response to an instruction from the control unit 172, the wireless communication unit 171 creates a CoAP message in which the code “2.05” (Content) is stored in the CoAP header and “0x80” is stored in the payload. Then, the wireless communication unit 162 generates a wireless packet including the created CoAP message in the payload of the wireless packet, sets the wireless address set in the own device as the source address, and sets the wireless address of the wireless communication unit 162 as the destination address. Using the set wireless ch, wireless packets are transmitted according to a predetermined wireless protocol (S17). Next, the wireless communication unit 162 receives the wireless packet addressed to itself, extracts the CoAP message, the code of the CoAP header is "2.05" (Content), and "0x80" is stored in the payload. Data indicating that the information is present is delivered to the control unit 161 (S18).

  The control unit 161 determines whether the time when the response message (that is, the response message) to the request message (that is, the request message) instructed to be transmitted in S13 is received from the wireless communication unit 162 is within the determination time set in S12. A determination is made (S19). When it is determined that it is within the determination time, the control unit 161 performs a predetermined process of recording data or transferring the acquired data to the lighting controller 12 based on the current dimming level included in the response message, for example. To do. On the other hand, when it is determined that the time is earlier or later than the determination time, the control unit 161 issues the request message instructing the same command again, or the lighting controller 12 indicates that the response message cannot be received within the determination time. To notify to.

  Next, with reference to FIG. 6, another example of message exchange between the wireless controller 16 and the wireless lighting control device 17 shown in FIG. 1 will be described. In the example shown in FIG. 6, it is assumed that the wireless address of the wireless communication unit 171 is set to “0021: 1E94”.

  Now, it is assumed that a command to be issued to the lighting device with wireless dimming function 17 is issued in the control unit 161 (S31). In this example, it is assumed that the issue of a command for dimming the current dimming level to “0x50” is determined for channel 0 of the wireless communication unit 171 in S31.

  The control unit 161 calculates the arrival time zone of the response message expected when the command is issued to the illumination device with wireless dimming function 17, and sets it as the determination time (S32). In S40, which will be described later, the control unit 161 determines that some problem may have occurred when the response message arrives before or after the determination time.

  Next, the control unit 161 specifies the URI as “coap: // 0021: 1E94 / levels / 0 / actual”, sets the CoAP method to “PUT”, and further sets the light control level value “0x50” to the payload. The wireless communication unit 162 is instructed to transmit the stored message (S33). The wireless communication unit 162 includes data indicating that the method is “PUT” in the header of the CoAP message and data indicating that the URI path (that is, the resource) is “/ levels / 0 / actual” in the field storing the option. And a data indicating the indicated value “0x50” in the payload are created to create a CoAP message. Then, the wireless communication unit 162 generates a wireless packet including the created CoAP message in the payload of the wireless packet, the wireless address set in the own device is the source address, and the wireless address of the wireless communication unit 171 is “0021: 1E94”. Is used as a destination address, and a wireless packet is transmitted according to a predetermined wireless protocol using the set wireless ch (S34).

  Next, the wireless communication unit 171 receives a wireless packet addressed to itself, extracts the CoAP message, the CoAP method is “PUT”, the resource is “/ levels / 0 / actual”, and the payload is Data indicating that the content of the data stored in is “0x50” or the like is delivered to the control unit 172 (S35). Since the CoAP method is “PUT” and the resource is “/ levels / 0 / actual”, the control unit 172 recognizes that the command instructed is the “DIRECT ARC POWER CONTROL” command by DALI. To do. Then, the control unit 172 sets the dimming level to the instruction value “0x50” / “0xFE” (0xFE is the instruction value of the dimming level 100%) × 100% duty ratio (= on / (on + off) time ratio). Then, a control signal for that is generated and output to the illumination unit 173 (S36). Then, the control unit 172 instructs the wireless communication unit 171 to return a response message containing the changed current dimming level value (“0x50”) of the lighting unit 173 as the execution result of the command. (S37).

  In response to an instruction from the control unit 172, the wireless communication unit 171 stores a code “2.04” (Changed) in the CoAP header and creates a CoAP message in which “0x50” is stored in the payload. Then, the wireless communication unit 171 generates a wireless packet including the created CoAP message in the payload of the wireless packet, and sets the wireless address set in the own device as the source address and the wireless address of the wireless communication unit 162 as the destination address. Using the set wireless ch, wireless packets are transmitted according to a predetermined wireless protocol (S38). Next, the wireless communication unit 162 receives the wireless packet addressed to itself, extracts the CoAP message, the code of the CoAP header is "2.04" (Changed), and "0x50" is stored in the payload. The data indicating that the information is present is delivered to the control unit 161 (S39).

  The control unit 161 determines whether the time at which the response message (that is, the response message) to the request message (that is, the request message) instructed to be transmitted in S33 is received from the wireless communication unit 162 is within the determination time set in S32. A determination is made (S40). When it is determined that it is within the determination time, the control unit 161 performs a predetermined process of recording data or transferring the acquired data to the lighting controller 12 based on the current dimming level included in the response message, for example. To do. On the other hand, when it is determined that the determination time is earlier or later than the determination time, the control unit 161 reissues a request message instructing the same command, issues a command inquiring the current dimming level, or determines whether or not the determination time is reached. To notify the lighting controller 12 that the response message could not be received.

  Next, with reference to FIG. 7, the exchange of messages between the wireless controller 16 shown in FIG. 1, the external wireless unit 22, and the lighting device with a light control function 23 will be described. In the example shown in FIG. 7, it is assumed that the wireless address of the wireless communication unit 221 is set to “0021: 1E95”.

  Now, it is assumed that a command to be issued to the lighting device with a light control function 23 is issued in the control unit 161 (S51). In this example, it is assumed that the issue of a command for dimming the current dimming level to “0x50” is determined for channel 0 of the wireless communication unit 221 in S51.

  The control unit 161 calculates the arrival time zone of the response message expected when the command is issued to the lighting device with dimming function 23, and sets it as the determination time (S52). In S60, which will be described later, the control unit 161 determines that some problem may have occurred if the response message arrives before or after the determination time.

  Next, the control unit 161 specifies the URI as “coap: / 0021: 1E95 / levels / 0 / actual”, sets the CoAP method to “PUT”, and further sets the light control level instruction value “0x50” to the payload. The wireless communication unit 162 is instructed to transmit the stored message (S53). The wireless communication unit 162 includes data indicating that the method is “PUT” in the header of the CoAP message and data indicating that the URI path (that is, the resource) is “/ levels / 0 / actual” in the field storing the option. And a data indicating the indicated value “0x50” in the payload are created to create a CoAP message. Then, the wireless communication unit 162 generates a wireless packet including the created CoAP message in the payload of the wireless packet, the wireless address set in the own device as the source address, and the wireless address of the wireless communication unit 221 “0021: 1E95”. Is used as a transmission destination address, and a wireless packet is transmitted according to a predetermined wireless protocol using the set wireless ch (S54).

  Next, the wireless communication unit 221 receives the wireless packet addressed to itself, extracts the CoAP message, the CoAP method is “PUT”, the resource is “/ levels / 0 / actual”, and the payload is Data indicating that the content of the data stored in is 0x50 or the like is delivered to the control unit 222 (S55). Since the CoAP method is “PUT” and the resource is “/ levels / 0 / actual”, the control unit 222 recognizes that the instructed command is the “DIRECT ARC POWER CONTROL” command by DALI. To do. Then, the control unit 222 sets the dimming level to the instruction value “0x50” / “0xFE” (0xFE is the instruction value of the dimming level 100%) × 100% duty ratio (= on / (on + off) time ratio). Then, a PWM (Pulse Width Modulation) signal or the like is output to control the illumination unit 231 (S56). Then, the control unit 222 instructs the wireless communication unit 221 to return a response message containing the value (“0x50”) of the current dimming level of the lighting unit 231 as the execution result of the command. (S57).

  In response to an instruction from the control unit 222, the wireless communication unit 221 stores the code “2.04” (Changed) in the CoAP header and creates a CoAP message in which “0x50” is stored in the payload. Then, the wireless communication unit 221 generates a wireless packet that includes the created CoAP message in the payload of the wireless packet, sets the wireless address set in its own device as the source address, and sets the wireless address of the wireless communication unit 162 as the destination address. Using the set wireless channel, wireless packets are transmitted according to a predetermined wireless protocol (S58). Next, the wireless communication unit 162 receives the wireless packet addressed to itself, extracts the CoAP message, the code of the CoAP header is "2.04" (Changed), and "0x50" is stored in the payload. Data indicating that the information is present is delivered to the control unit 161 (S59).

  The control unit 161 determines whether the time when the response message (that is, the response message) to the request message (that is, the request message) instructed to be transmitted in S53 is received from the wireless communication unit 162 is within the determination time set in S52. A determination is made (S60). When it is determined that it is within the determination time, the control unit 161 performs a predetermined process of recording data or transferring the acquired data to the lighting controller 12 based on the current dimming level included in the response message, for example. To do. On the other hand, if it is determined that the determination time is earlier or later than the determination time, the control unit 161 reissues a request message instructing the same command, or issues a command inquiring the current dimming level, for example, within the determination time. To notify the lighting controller 12 that the response message could not be received.

  As described above, according to the present embodiment, the control unit 161 is a character string representing the address of the wireless communication unit 171 or 221, and a predetermined command related to the control of the illumination unit 173 or 231 by the control unit 172 or 222. Is specified, the wireless communication unit 162 is instructed to transmit a message including a character string representing a command, and the control unit 161 determines whether a response message is received within the determination time. According to this configuration, it is possible to access using the address of the wireless communication unit 171 or 221. Therefore, it is not necessary to use a system such as a DNS (Domain Name System) which requires a relatively long processing time to access. Further, since the command for controlling the illumination units 173 and 231 can be directly designated, the control similar to the conventional one can be easily performed. Further, by determining whether or not the response message is received within the determination time, for example, it is possible to recognize that the response message was not returned within the normal time, and in that case, reconfirm the control state. , You can resend the command. Therefore, according to the present embodiment, it is possible to secure the communication quality in wireless communication and control the lighting equipment by a simple method.

  Further, according to the present embodiment, the command for controlling the illumination unit 173 and the illumination unit 231 at the level of the predefined command is included in the URI. Therefore, the command can be specified in the form of access to the URI. Therefore, according to the present embodiment, it is possible to easily and appropriately coordinate a plurality of software. That is, the software executed by the control unit 161 and the software executed by the control unit 172 or the software executed by the control unit 222 can be appropriately associated with each other. Further, since the message is generated according to CoAP that can be easily converted to HTTP (Hypertext Transfer Protocol), it is possible to easily cooperate with software that uses HTTP.

  Further, since the command included in the URI is made to correspond to the command specified by DALI, it is possible to enhance versatility and use it in many lighting devices. Further, since the format of the message has the format defined by CoAP, versatility can be enhanced.

  Further, in the above-described embodiment, since there is not necessarily a restriction that TCP must be used, for example, a DALI as an application layer 403 is provided on a physical layer 401 and a MAC layer 402 (data link layer) of wireless communication. It is possible to devise a combination of protocols, such as using a protocol stack equipped with software to perform compliant command conversion and control processing, etc., and it is expected that the combination will reduce the data amount of one message. it can. In addition, it is possible to easily secure responsiveness by adopting a configuration in which time does not fluctuate.

  The embodiment of the present invention is not limited to the above. For example, the instruction for creating and transmitting the CoAP message performed by the control unit 161 included in the wireless controller can be issued from the lighting controller 12, the terminal 13, or the building management system 11. In that case, the control unit 161 can be considered to function integrally with the control unit such as the lighting controller 12, the terminal 13, or the computer included in the building management system 11. Further, the illumination control system 1 shown in FIG. 1 can appropriately make changes such as integrating the blocks or separating and arranging the blocks separately. Further, the processing performed by each block can be appropriately performed by another block or can be performed in a distributed manner. The program executed by the computer included in each block shown in FIG. 1 can be distributed in part or in whole via a computer-readable recording medium or a communication line.

  Further, according to the configuration of the present embodiment, the control unit 161 specifies the character string representing the address of the wireless communication unit 171 and the predetermined command related to the control of the illumination unit 173 by the control unit 172, thereby making the command The wireless communication unit 162 is instructed to transmit a message including a character string indicating that, and the control unit 161 determines whether or not the response message is received within the determination time. According to this configuration, since it is possible to access using the address of the wireless communication unit 171, it is not necessary to use a system such as DNS which requires a relatively long processing time to access. Moreover, since a command for controlling the illumination unit 173 can be designated, control similar to the conventional one can be easily performed. Further, by determining whether or not the response message is received within the determination time, for example, it is possible to recognize that the response message was not returned within the normal time, and in that case, reconfirm the control state. , You can resend the command. Therefore, according to the present embodiment, it is possible to secure the communication quality in wireless communication and control the lighting equipment by a simple method.

  Further, as described above, the lighting control system 1 can individually control the lighting device with a wireless dimming function 17 via the wireless controller 16 based on the user's operation. Further, the lighting control system 1 individually controls the respective lighting devices such as the lighting device with a light control function 23 and the lighting device with a light control function 29 by the same process, in addition to the wireless lighting device with a light control function 17. be able to. Further, by registering a plurality of lighting devices to be collectively controlled in the same group, it is possible to instruct to adjust the dimming rate of the lighting devices of the group by one operation. By the user's operation or control from the building management system 11, the lighting control system 1 can control the lighting devices such as the lighting device with wireless dimming function 17 individually or in group units.

  In addition, the lighting control system 1 may control the wireless lighting control device 17 and the like using various sensors. For example, the lighting control system 1 may perform automatic control that individually or collectively adjusts the lighting state of each lighting device so as to effectively use daylight by using a sensor for measuring brightness.

In addition, the lighting control system 1 is configured to cooperate with a motion sensor, an entrance / exit security system (not shown), a schedule system, etc., so that the user can control the lights to be turned off when the user is absent or based on a preset schedule. May be.
Thus, the lighting control system 1 controls the lighting state collectively without performing the above-mentioned turning-off control when the user is absent or controlling the lighting state for each area based on a preset schedule. It is possible to reduce the power consumption of the lighting device as compared with.

Further, the lighting control system 1 may apply a dimming control method defined by DALI or a dimming control method by PWM control as a method of dimming control for the lighting device.
In addition, the building management system 11 can be configured as a building energy management system (BEMS) that manages the control states of various equipment (not shown). For example, the lighting control system 1 may be configured to cooperate with various types of equipment related to the building management system 11 to visualize the control status of the air conditioning equipment and the energy usage status such as power consumption.

  Further, when the lighting control system 1 is configured to use the wireless communication line, it is possible to eliminate the need for the control wiring for connecting the respective lighting devices included in the range where the wireless communication line is used. In the above case, according to this lighting control system 1, when installing the system, when renewing a building or changing the layout of an office, etc., laying or changing control wiring to each lighting device is involved. Wiring work is unnecessary.

  The lighting control system 1 can also be configured by omitting the automatic control function corresponding to various sensors. With such a configuration, the setting device 24, the operation device 25, and the like can be operated to control the lighting state of the lighting device via the wireless communication line. When configured as described above, the system can be configured without using a gateway or the like for converting the communication system, and the configuration of the lighting control system 1 can be simplified. For example, the setting device 24 and the operation device 25 may be portable terminal devices such as smartphones and tablet terminals. Accordingly, the lighting control system 1 can wirelessly control each lighting fixture with a light control function from a terminal device such as a smartphone or a tablet terminal.

  In addition, the lighting control system 1 uses a brightness sensor or a human sensor to suppress the use of the lighting device during the daytime, or automatically turn off the light when it is absent. It is possible to finely control the state and reduce the power consumption of the lighting.

  Further, in the above embodiment, when the wireless controller 16 and the lighting device 17 with the wireless dimming function communicate using the protocol stack structure including the physical layer, the MAC layer, and the application layer, the wireless controller 16 The processing of the application layer is to generate a message that specifies the identification information of the MAC layer used for communication by the URI, but the same configuration can be adopted not only for wireless communication but also for wired communication. For example, instead of communication by DALI between the wired controller 14 and the wired dimming lighting device 15 shown in FIG. 1, a physical connection between the wired controller 14 and the wired dimming lighting device 15 is performed. Communication is performed using a protocol stack structure including a layer, a MAC layer, and an application layer, and in the wired controller 14, the application layer process generates a message that specifies the identification information of the MAC layer used for communication with a URI. It can be done.

  By the way, in recent years, in addition to improving the efficiency of equipment that consumes electric power, the evolution of automatic equipment control technology, that is, delicate control that suppresses unnecessary electric power while responding to various needs of users is demanded. .. In response to such a demand, for example, it is necessary to appropriately link a plurality of software such as software for realizing a control at a level closer to that of hardware and software for realizing a user-friendly user interface. Becomes In addition, wireless communication has come to be used for the purpose of collecting sensor information. When other unplanned systems coexist in the same frequency band, radio communication interference may occur. Even in such a situation where interference occurs, it is necessary to secure desired communication quality.

  However, in order to secure the communication quality of wireless communication, a configuration is conceivable in which a plurality of software is used to exchange messages. For example, a protocol such as XML (Extensible Markup Language) can secure communication quality by a retransmission process or the like, but is not suitable for using the retransmission process for control. In particular, when transmitting on a wireless line having a relatively low communication speed, the time required for transmission fluctuates, and thus it is difficult to strictly manage the time from the request message to the response message. On the other hand, in DALI, a time limit is set between the forward frame transmitted from the master to the slave and the backward frame transmitted from the slave to the master in response to the forward frame. That is, the communication quality can be improved by appropriately linking software having time constraints such as DALI and software that is difficult to comply with time constraints such as software used when communicating using wireless communication. Ensuring is an issue.

  The present embodiment has the following configuration to solve the above problem of ensuring communication quality. That is, in the present embodiment, the control unit 161 specifies a character string representing the address of the wireless communication unit 171 or 221 and a predetermined command related to the control of the illumination unit 173 or 231 by the control unit 172 or 222. , And instructs the wireless communication unit 162 to transmit a message including a character string representing a command. Further, the control unit 161 determines whether or not the response message is received within the determination time. According to this configuration, it is possible to access using the address of the wireless communication unit 171 or 221, so that it is not necessary to use a system such as DNS, which takes a relatively long time to access. In addition, since a command for controlling the illumination unit 173 or 231 can be designated, control similar to the conventional one can be easily performed. Further, by determining whether or not the response message is received within the determination time, for example, it is possible to recognize that the response message was not returned within the normal time, and in that case, reconfirm the control state. , You can resend the command.
