  In addition to the case where the communication unit 160 is not performing broadcast transmission of the communication data D or performing carrier sense therefor, for example, as shown in FIG. 7, a setting channel for communication with the management terminal device 10 is set. And the operation channel used for communication with the other lighting device 100 are alternately switched at predetermined intervals, and the asynchronous communication data D transmitted from the management terminal device 10 or broadcast transmission from the other lighting device 100 Waiting for the received asynchronous communication data D.

  Then, as shown in FIG. 7, the communication unit 160 waits for reception of the communication data D (FIG. 7A) broadcast from another lighting device 100, and When the frame synchronization included in the detection information is received (FIG. 7B), all information of the detection information is received, and the control information is acquired by the control unit 140 (FIG. 7C). However, the communication unit 160 is receiving all the detection information being received even when the detection information is being received and it is time to switch to the setting channel before receiving all the detection information. Until it is done, receive operation is performed as an operation channel. At this time, when acquiring the detection information, the control unit 140 outputs a control signal for starting the lighting control of the illumination light source L to the illumination unit 120 (FIG. 7D).

  The communication unit 160 is not directly or using a short-range wireless communication standard such as BLUETOOTH (registered trademark), wireless LAN (WLAN: Wireless Local Area Network), or wireless PAN (WPAN: Wireless Personal Area Network). Wireless broadcast communication and reception thereof may be performed via the access point.

  The control unit 140 includes a timer and is a unit for controlling the illumination unit 120 and the communication unit 160 based on the detection signal output from the sensor unit 130.

  Specifically, when the control unit 140 receives a detection signal output from the sensor unit 130 in conjunction with a timer, that is, when a change in the surrounding state is detected, the lighting unit 120 under management is controlled. In other words, a lighting control process (hereinafter referred to as “detection lighting control process”) for turning on the illumination light source L of the lighting unit 120 of the own device is executed, and wireless broadcast communication in the other lighting devices 100 is monitored. On the other hand, a broadcast transmission process is performed in which detection information indicating that the surrounding state change is detected is transmitted to another illumination control device by wireless broadcast communication.

  In addition, when the control unit 140 receives detection information transmitted from another lighting device 100 by wireless broadcast communication, the control unit 140 turns on the lighting unit 120 of the own device based on the specific information stored in the data storage unit 110. Whether or not to turn on the illumination light source L in the lighting unit 120 of the own device, and if it is determined to be turned on, a lighting control process (hereinafter referred to as “reception lighting control”) that turns off the light after a predetermined period. Process "). At this time, if the control unit 140 transmits detection information from itself by wireless broadcast communication, the control unit 140 determines whether the continuation is possible or not, and if the predetermined condition is satisfied, Stop broadcasting information.

  Details including the detection lighting control process, the broadcast transmission process, and the reception lighting control process in the control unit 140 of this embodiment will be described later.

  The power supply unit 150 includes an AC power supply and various circuits for supplying power to the light source such as AC / DC conversion.

[3.2] Control unit [2.2.1] Detection lighting control process Next, the detection lighting control process in the control unit 140 of this embodiment is demonstrated.

  As the detection lighting control process, the control unit 140 turns on the illumination light source L of the illumination unit 120 under management when a change in the surrounding state is detected, and elapses of a predetermined time from the start of lighting of the illumination light source L. Later, a control process for turning off the lighting unit 120 is executed.

  Specifically, when the control unit 140 receives the detection signal output from the sensor unit 130, the control unit 140 controls an energization circuit (not shown) of the illumination unit 120 to turn on the energization to the illumination light source L and to turn on the illumination light source L. Start lighting.

  In addition, the control unit 140 starts lighting the illumination light source L, starts counting by a built-in timer, and detects that a predetermined time has elapsed (for example, 30 seconds have elapsed) by the timer, the control unit 140 The energization control circuit is controlled to stop the energization and turn off the illumination light source L.

  For example, when the control unit 140 receives a detection signal (that is, a pulse) as shown in FIG. 5B output from the sensor unit 130, the control unit 140 controls the energization control circuit of the illumination unit 120 to be turned on, and The light source L is turned on. At this time, the control unit 140 starts counting the timer, and controls the energization control circuit to turn off after a predetermined time has elapsed (for example, after 30 seconds) to turn off the illumination light source L.

  Note that the control unit 140 controls the lighting light source L to be turned off after the lighting light source L is turned on based on a time predetermined by the management terminal device 10.

[2.2.2] Broadcast transmission control processing Next, the broadcast transmission control processing in the control unit 140 of this embodiment will be described.

  As a broadcast transmission control process, the control unit 140 receives the detection signal output from the sensor unit 130 to the communication unit 160 and controls the communication unit 160 to detect the state change with respect to the other lighting devices 100. The detection information indicating that it has been performed is transmitted. In particular, the control unit 140 of the present embodiment transmits a plurality of pieces of detection information (that is, the above-described blocks) in order to cause the lighting devices 100 of the same group or lighting group to reliably receive the communication data D (for example, the above-described block). The communication data D to be transmitted five times) is repeatedly transmitted a predetermined number of times.

(Broadcast transmission control)
Specifically, the control unit 140 uses the own device ID, system ID, and group ID stored in the data storage unit 110, the own device ID, a transmission destination ID as a broadcast transmission, and a detection signal. The communication unit 160 generates detection information including a command type and a command indicating that the communication information is, and communication data D including the detection information continuously in a predetermined set (for example, five sets). To generate. Then, the control unit 140 causes the communication unit 160 to execute broadcast transmission by repeating the communication data D in which five pieces of detection information are transmitted in a predetermined number of times while performing carrier sense.

  For example, as shown in FIG. 6, the control unit 140 causes the communication unit 160 to perform carrier sense, and simultaneously broadcasts the communication data D in which five pieces of detection information are sent, and simultaneously transmits the communication data D. Each time a report is transmitted, a suspension period (for example, 50 ms to 380 ms) is set at random, and after the suspension period has elapsed, the communication unit 160 transmits the communication data D, so that a predetermined number of times (specifically, 3) repeat broadcast transmission is executed.

  Further, when the communication data D is repeatedly transmitted a predetermined number of times, and when the predetermined number of broadcast transmissions are not completed (that is, the predetermined number of repeated communication data D is transmitted). In the case where the set is incomplete, while the set is incomplete (hereinafter, “broadcast communication is incomplete”), communication transmitted from the lighting device 100 of the same group to which the own unit belongs When the data D is received, the broadcast transmission control process being executed is stopped. The cancellation of the broadcast transmission control process will be described later.

(Career sense)
The control unit 140 detects the presence / absence of a broadcast transmission based on the other lighting device 100 when the communication data D is broadcasted repeatedly a predetermined number of times (that is, when the detection information is transmitted), Based on the presence / absence of broadcast transmission of the other lighting device 100, carrier sense is performed to determine whether or not transmission of detection information to be transmitted from the own device is possible.

  Specifically, the control unit 140 controls the communication unit 160 when it repeatedly transmits the communication data D a predetermined number of times, and each time it repeats the broadcast communication of the communication data D, The carrier sense for determining whether or not the wireless broadcast communication of the machine is possible is executed.

  Then, the control unit 140 randomly calculates a standby time (30 ms to 40 ms), and after the calculated standby time has elapsed, the communication unit 160 performs carrier sense again, while the other lighting device 100 performs communication data. D is broadcast.

  In addition, when the control unit 140 is waiting for transmission of the communication data D by carrier sense, the broadcast transmission transmitted from the lighting device 100 of the group to which the own unit belongs is performed by the reception lighting control process described later. In the case of reception, the communication unit 160 stops the transmission of the communication data D in the detection information itself as in the case of the broadcast transmission control.

[2.2.3] Reception Lighting Control Process Next, the reception lighting control process in the control unit 140 of the present embodiment will be described with reference to FIGS. 8 and 9 are diagrams for explaining the broadcast transmission control process stop determination (stop determination when broadcast communication is not completed) in the control unit 140 of the present embodiment. These are the figures for demonstrating the cancellation determination (stop determination in a carrier sense retry waiting) of the broadcast transmission control process in the control unit 140 of this embodiment.

(Lighting control of lighting unit)
As the reception lighting control process, the control unit 140 receives the communication data D broadcast from the other lighting devices 100 while the communication unit 160 is waiting for reception of the operation channel, and based on the received communication data D. The lighting control of the lighting unit 120 is executed.

  That is, the control unit 140 determines whether or not to turn on the lighting unit 120 of the own device based on the specific information included in the detection information of the received communication data D, and determines the lighting unit 120 based on the determination result. Execute lighting control.

  Specifically, when the control unit 140 receives the communication data D broadcasted from the other lighting device 100, the control unit 140 broadcasts the illumination transmitted based on the specific information included in the detection information of the received communication data D The group ID of the device 100 (that is, the group ID of the transmission source) is specified.

  In addition, the control unit 140 compares the belonging group ID of the identified transmission source with the belonging group ID and lighting group ID that are identification information of the own device stored in the data storage unit 110, and When at least one of the group IDs of the own device matches, the illumination unit 120 under control is controlled, and the illumination light source L of the illumination unit 120 is turned on as in the detection lighting control process. Then, the control unit 140 executes a control process for turning off the illumination unit 120 after a predetermined time has elapsed from the start of lighting of the illumination light source L.

  On the other hand, the control unit 140 compares the belonging group ID of the identified transmission source with the belonging group ID and lighting group ID that are identification information of the own device stored in the data storage unit 110. If both of the group IDs of the own devices do not match, the lighting unit 120 lighting control is not executed and the current status is maintained (that is, nothing is done).

  For example, in the example shown in FIG. 2, the group ID of the own device stored in the data storage unit 110 is “G5”, and the lighting group IDs of the own device are groups “G4”, “G6”, and “G7”. When the source group ID of the transmission source is “G1”, the control unit 140 determines that the group ID and lighting group ID of the own device do not match, and does not execute the control process of the lighting unit. On the other hand, similarly, when the own group ID is “G5” and the own group ID is “G4”, “G6”, and “G7”, the source group is “ In the case of “G4”, “G5”, “G6”, or “G7”, the control unit 140 turns on the illumination light source L of the illumination unit 120 under management and starts to turn on the illumination light source L for a predetermined time. After the elapse of time, a control process for turning off the lighting unit 120 is executed.

(Broadcast transmission control processing cancellation determination)
The control unit 140 is a case where the reception lighting control process for receiving the communication data D transmitted from the other lighting device 100 is executed during the broadcast transmission control process, and is specified based on the received communication data D. When the group ID of the other device matches the ID of the group to which the own device belongs, the communication unit 160 is controlled to execute a cancel process for canceling the broadcast transmission control process being executed.

  In such a case, it is assumed that the control unit 140 is already linked and controlled based on the detection information of the other lighting devices 100 to the lighting devices 100 in the same group, in order to prevent congestion. When the broadcast communication is not completed or the carrier sense retry is waited, the communication unit 160 is stopped from broadcasting the communication data D in the detection information.

  Specifically, the control unit 140 repeatedly transmits the communication data D a predetermined number of times, and waits for transmission of the next communication data D or transmits the communication data D by carrier sense. When the broadcast transmission transmitted from the lighting device 100 of the group to which the own device belongs is received by the reception lighting control process during the standby (hereinafter also referred to as “waiting for carrier sense retry”), The communication unit 160 is stopped from broadcasting the communication data D in the detection information.

  That is, the control unit 140 is the same when the broadcast communication is incomplete and waiting for transmission of the next communication data D, or when waiting for transmission of the communication data D by carrier sense. When the communication data D broadcasted from the other lighting devices 100 belonging to the non-identical group including the lighting group is received, the communication unit 160 is maintained as it is and the communication unit 160 is maintained after a predetermined standby time. In addition, the communication data D is broadcasted to another lighting device 100 while performing carrier sense again.

  However, when receiving the communication data D broadcasted from the lighting device 100 of the same belonging group, the control unit 140 is interlocked and controlled based on the detection information of the other lighting devices 100 in the same belonging group. Therefore, in order to prevent congestion, the communication unit 160 stops the broadcast transmission of the communication data D in the detection information.

(Example of reception lighting control processing when broadcast communication is incomplete)
For example, as shown in FIG. 8, when the transmission of the communication data D repeated a predetermined number of times is set as one set, the control unit 140 transmits the communication data D when broadcast communication of the set is incomplete. When communication data D including a detection signal indicating a change in the surrounding state of the sensor unit 130 of the illumination device 100 is received from the illumination device 100 in the same group during standby, In 160, the broadcast transmission of the communication data D in the detection information is stopped.

  Note that the example shown in FIG. 8 is a case where the other device does not receive the communication data D that has been broadcast, but has received the communication data D based on the detection of the sensor unit 130 of the own device without receiving the broadcast data D due to the deterioration of the radio wave environment. There is an example in which the broadcast transmission of the communication data D in the own machine is stopped based on the broadcast-transmitted communication data D.

  At this time, the control unit 140 controls the lighting unit 120 of the own device based on the communication data D received (that is, in conjunction with a change in the surrounding state in the other lighting device 100), and the lighting unit L of the own device. Is designed to light up.

  Further, as shown in FIG. 8, the control unit 140 of the own device, like the lighting device 100 in the same group, waits for reception by alternately switching between the operation channel and the setting channel while broadcast communication is not completed. To do.

  On the other hand, for example, as shown in FIG. 9, when the transmission of the communication data D repeated a predetermined number of times is set as one set, the control unit 140 is not completing the broadcast communication of the set, and the communication data D Detection indicating a change in the surrounding state of the sensor unit 130 of the lighting device 100 from the lighting device 100 in the non-identical group (for example, the lighting device 100 of the same lighting group) When the communication data D including the signal is received, the control unit 140 maintains the execution of the broadcast transmission process without stopping the broadcast transmission of the communication data D in its own device.

  The example shown in FIG. 9 is an example showing a state in which the other lighting device 100 and its own lighting device 100 are transmitting communication data D based on a surrounding state change detected by their own sensor unit 130. is there.

(Example of reception lighting control processing during carrier sense retry standby)
For example, as shown in FIG. 10, the control unit 140 includes a detection signal indicating a change in the surrounding state of the sensor unit 130 of the lighting device 100 from the lighting device 100 in the same group during the carrier sense retry standby. When the communication data D is received, the communication unit 160 is stopped from broadcasting the communication data D in the detection information.

  Specifically, when the control unit 140 causes the communication unit 160 to perform carrier sense at the time of transmission of the communication data D, in such a case, the broadcast communication is detected from the other lighting device 100. Therefore, the control unit 140 causes the communication unit 160 to stop broadcast transmission of the communication data D, and shifts to a carrier sense retry standby.

  And the control unit 140 receives the broadcast transmission transmitted from the other lighting device 100 by executing the reception lighting control process during the carrier sense retry standby, and the same group ID as that of the own device. If they match, the communication unit 160 stops broadcasting the communication data D in the detection information without executing the next carrier sense.

  Note that the communication unit 160 waits for communication from another lighting device 100 or the management terminal device 10 while switching between the operation channel and the setting channel at a predetermined timing, even when waiting for carrier sense retry.

  On the other hand, for example, as shown in FIG. 11, the control unit 140 executes the reception lighting control process during the carrier sense retry standby, and based on the received communication data D in the lighting control of the lighting unit 120. If the group ID of the identified other device does not match the ID of the group to which the own device belongs, the execution of the broadcast transmission control process being executed is maintained, and carrier sense is executed again after a predetermined time has elapsed, If no other broadcast transmission is detected, the communication data D in the own device is broadcast.

[4] Lighting Control Process [4.1] Reception Lighting Control Process Next, the reception lighting control process in the lighting device 100 of the present embodiment will be described using FIG. In addition, FIG. 12 is a flowchart which shows the reception lighting control process in the illuminating device 100 of this embodiment.

  In this operation, each ID is set by the management terminal device 10 and stored in the data storage unit 110.

  First, when the communication unit 160 receives communication data D transmitted from another lighting device 100 during standby of the operation channel (step S101), the control unit 140 operates in conjunction with the communication unit 160 to detect detection information as actual data. Is acquired (step S102).

  Next, the control unit 140 identifies the belonging group ID included in the detection information (that is, the belonging group ID of the transmission source) (step S103), and stores the identified belonging group ID and its own device stored in the data storage unit 110. It is determined whether or not any of the belonging group ID or lighting group ID matches (step S104).

  At this time, if the control unit 140 determines that the identified belonging group ID of the transmission source matches either the belonging group ID or lighting group ID of the own device stored in the data storage unit 110, the control unit 140 proceeds to step S105. The process proceeds to this process, and if it is determined that neither the belonging group ID of the identified transmission source matches the belonging group ID or lighting group ID of the own device stored in the data storage unit 110, this operation is terminated.

  Next, when the control unit 140 determines in the process of step S104 that the identified belonging group ID of the transmission source matches either the belonging group ID or lighting group ID of the own device stored in the data storage unit 110. Controls the illumination unit 120 to start lighting the illumination light source L (step S105). The illumination unit 120 turns off the illumination light source L after a predetermined time has elapsed based on the count of the timer.

  Finally, the control unit 140 determines whether or not it is a broadcast transmission control process (step S106), and if it is determined that the broadcast transmission control process is being performed, the transmission received in the process of step S104. It is determined whether or not the original group ID matches the own group ID (step S107).

  At this time, if the control unit 140 determines that the belonging group ID of the transmission source identified in the process of step S104 matches the belonging group ID of the own device, the control unit 140 executes stop control in the broadcast transmission control process. (Step S108) When this operation is finished and it is determined that the belonging group ID of the transmission source and the belonging group ID of the own device do not match (that is, the belonging of the transmission source specified in the process of Step S104) If it is determined that the group ID and the lighting group ID of the own device match, this operation is terminated as it is.

[4.2] Broadcast Transmission Control Process Next, a broadcast transmission control process in the lighting device 100 of the present embodiment will be described with reference to FIG. In addition, FIG. 13 is a flowchart which shows the broadcast transmission control process in the illuminating device 100 of this embodiment.

  In this operation, each ID is set by the management terminal device 10 and stored in the data storage unit 110.

  First, when a detection signal is output by the sensor unit 130 (step S201), the control unit 140 controls the illumination unit 120 to start lighting the illumination light source L (step S202). The illumination unit 120 turns off the illumination light source L after a predetermined time has elapsed based on the count of the timer.

  Next, the control unit 140 reads the specific information from the data storage unit 110 and causes the communication unit 160 to generate detection information and communication data D (step S203).

  Next, the control unit 140 causes the communication unit 160 to perform carrier sense and determines whether or not the generated communication data D can be transmitted (step S204). At this time, if the communication unit 160 determines that the broadcast transmission of the communication data D generated by the carrier sense is possible, the control unit 140 proceeds to the process of step S221, and the communication unit D of the communication data D generated by the carrier sense is transferred. When determining that broadcast transmission is impossible, the control unit 140 calculates a carrier sense retry waiting time by a predetermined calculation (step S211).

  Next, the control unit 140 starts counting the carrier sense retry waiting time calculated by the timer (hereinafter also referred to as a unit “retry waiting time”) (step S212).

  Next, the control unit 140 determines whether or not the retry waiting time has elapsed while determining whether or not the broadcast transmission control process is stopped in the reception lighting control process until the retry waiting time elapses (step S213). Is determined (step S214).

  At this time, if the control unit 140 determines that the broadcast transmission control process stop control has been started in the reception lighting control process, the control unit 140 ends this operation and performs the broadcast transmission control process in the reception lighting control process. If it is determined that the retry waiting time has elapsed without determining that the stop control has started, the process returns to step S204.

  On the other hand, if it is determined in step S204 that the communication unit 160 can broadcast the communication data D generated by carrier sense, the control unit 140 broadcasts the communication data D (step S221). It is determined whether or not to repeatedly transmit communication data D, that is, whether or not a predetermined number of repeated transmissions have been completed (step S222).

  At this time, if the control unit 140 determines that the predetermined number of repeated transmissions have been completed, the control unit 140 ends this operation, and if the control unit 140 determines that the predetermined number of repeated transmissions has not ended. Then, a standby time (hereinafter referred to as “retransmission standby time”) when broadcast communication is not completed is calculated by a predetermined calculation.

  Next, the control unit 140 starts counting the standby time calculated by the timer (step S224).

  Next, the control unit 140 determines whether or not the broadcast transmission control process stop control is started in the reception lighting control process (step S225), and determines whether or not the standby time during the incomplete broadcast communication has elapsed. (Step S226).

  At this time, if the control unit 140 determines that the broadcast transmission control process stop control has been started in the reception lighting control process, the control unit 140 ends this operation and performs the broadcast transmission control process in the reception lighting control process. If it is determined that the standby time has not been completed without determining that the stop control has been started, the process proceeds to step S204.
