Description

  The present invention relates to an illumination control system for a railway vehicle, and an illumination control device and an illumination device provided in the illumination control system.

  Conventional illumination control systems for railway vehicles lay control wires along with power supply wires to adjust the brightness of the interior lighting (dimming) and to adjust the lighting color (toning). In railway vehicles that use LED (light-emitting diode) lighting as the main lighting instead of the fluorescent lamps used in the past, the power supply that supplies power to the LED lighting fixtures can be consolidated, so the fluorescent lighting is the main lighting. Compared to the above, the dimming control can be realized only by arranging a small number of dimming control wiring lines from the dimming control device to the power supply device. Furthermore, LEDs have a surface that is easy to introduce dimming control, such as high responsiveness (controllability) compared to fluorescent lamps (see Patent Document 1).

  However, in railway vehicles, a high-voltage circuit that mainly supplies power to the main motor, a low-voltage circuit that supplies power to service equipment such as air conditioners, a transmission circuit that transmits information to information terminals in the vehicle, Since various circuits such as signal circuits such as security equipment are mounted, the circuit is easily affected by radiation noise generated from the various circuits described above. In addition, the control of newly installed LEDs requires the installation of new control lines and the time required for installation, which has hindered the introduction of new LED lighting to existing vehicles. It was.

(First embodiment)
A first embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a configuration diagram of a lighting control system according to the first embodiment of the present invention. FIG. 2 is a configuration diagram of the illumination control apparatus shown in FIG. FIG. 3 is an explanatory diagram of a transmission frame format used in the lighting control system shown in FIG. FIG. 4 is a configuration diagram of the illumination device shown in FIG. FIG. 5 is a flowchart of the setting operation of the illumination control device and the identification ID of the lighting device shown in FIG.

  FIG. 1 shows a schematic configuration of a lighting control system 1 of the present embodiment. Normally, the lighting control device 2 is placed in a crew room at the end of a railway vehicle (hereinafter referred to as a vehicle). Trains are assigned a knitting code according to the operation plan, and the trains are identified by the knitting code. Moreover, the illuminating device 3 is mainly placed in the passenger compartment of the vehicle and functions as an interior lamp. Further, the lighting control device 2 and the lighting device 3 are simultaneously fed by an existing power line or the like. As shown in FIG. 1, in order to exchange information wirelessly between the illumination control device 2 and the illumination device 3, each has means for performing wireless communication as described later.

  FIG. 2 is a configuration diagram of the illumination control device 2. The illumination control device 2 includes a dimming / toning control data generation unit 21, an identification ID encryption information setting unit 22, a multiplexing / packetizing unit 23, a memory circuit 24, a modulation circuit 25, and transmission / reception. A switching circuit 26, an antenna 27, a timing generation unit 28, a demodulation circuit 29, and a control circuit 2A are provided.

  The light control / color control data generation unit 21 generates light control / color control data. In the present embodiment, light control and color adjustment can be performed by transmitting the light control illumination command information to the plurality of illumination devices 3. The light control / color control data generation unit 21 generates light control / color control data that is the basis of the above-mentioned light control illumination command information. Here, dimming means changing the illuminance of the environment by controlling the luminance of the illumination, and toning means changing the chromaticity by changing the ratio of a plurality of colors. This is to provide a comfortable environment by adjusting the brightness (illuminance) and color condition (chromaticity) in the vehicle according to the environment.

  The identification ID encryption information setting unit 22 as a unique identification code setting unit and an initial identification code setting unit is set with an identification ID as a unique identification code for determining train formation. As the identification ID, an ID uniquely determined for each train formation by a dip switch or the like based on the formation number or the like is given in advance. The identification ID encryption information setting unit 22 is set with information for encrypting dimming illumination command information and identification code setting information described later. Various types of information transmitted from the lighting control device 2 are encrypted into packets having a format suitable for transmission. The encryption key is arbitrary, but by using a uniquely determined identification code as the encryption key, it is possible to save the trouble of sending the encryption key to the lighting device that performs decryption.

  The identification ID encryption information setting unit 22 is set with a free ID as an initial identification code. The free ID is an ID that is set in advance in common with the lighting control device 2 and the lighting device 3 regardless of the train organization and the like, and is set at the time of manufacture. The free ID is given in advance by a dip switch or the like.

  The free ID is used instead of the identification ID when setting the identification ID in the lighting device 3. For example, in the packet to be transmitted, the free ID is set in the area where the identification ID is set, and the identification ID is set in the data area, whereby the identification code setting information for setting the identification ID in the lighting device 3 is obtained. .

  The identification ID and the free ID are not limited to be set by a switch, and may be stored in a nonvolatile memory such as a ROM or an EEPROM. The free ID may be incorporated as a circuit that outputs a fixed value at the time of design or the like.

  The multiplexing / packetizing unit 23 packetizes the toning control data and the identification ID to generate dimming illumination command information, or packetizes the free ID and the identification ID to generate identification code setting information.

  FIG. 3 shows an example of a transmission frame format of a packet constituting dimming illumination command information and identification code setting information. The transmission frame format shown in FIG. 3 is arranged in the order of STX, Text, ETX, and SUM from the top. STX indicates the head of the frame and is composed of 8 bits. Text indicates transmission data and is composed of 128 bits. ETX indicates the end of Text and is composed of 8 bits. SUM indicates a checksum and is composed of 16 bits.

  Then, the 0th to 7th bits of Text are set as a field for setting a free ID or an identification ID, and the 8th bit and subsequent bits of Text are set as a field for data or the like. For example, in the case of identification code setting information, a free ID is set in the 0th to 7th bits of Text, and an 8-bit identification ID is set in the 8th and subsequent bits of Text. In the case of dimming illumination command information, the identification ID is set in the 0th to 7th bits of Text, and the toning control data is set in the 8th and subsequent bits of Text. Of course, this transmission frame format is also applied to information transmitted by the lighting device 3. For example, in the case of confirmation information (see the second embodiment), an identification ID is set in the 0th to 7th bits of Text, 8-bit serial number information is set after the 8th bit of Text.

  The memory circuit 24 stores various transmission information generated by the multiplexing / packetizing unit 23. The modulation circuit 25 reads various transmission information stored in the memory circuit 24 and modulates it to an appropriate carrier wave. The transmission / reception switching circuit 26 switches transmission or reception from the antenna 27 under the control of the control circuit 2A. In the case of transmission, the signal modulated by the modulation circuit 25 is output to the antenna 27 and transmitted to the illumination device 3. In the case of reception, the signal received by the antenna 27 is output to the demodulation circuit 29.

  The timing generator 28 controls the read timing of the memory circuit 24, the modulation timing of the modulation circuit 25, and the like. These timings are performed at a predetermined constant cycle (a constant time interval) or a random cycle. The random period is a period based on a random value within a range in which an upper limit and a lower limit are set.

  The demodulation circuit 29 demodulates the signal received by the antenna 27. The control circuit 2A receives transmission information from the lighting device 3 or the like from the signal demodulated by the demodulation circuit 29, and controls the memory circuit 24, the modulation circuit 25, or the like based on the received information.

  As is apparent from the above description, the multiplexing / packetization unit 23, the memory circuit 24, the modulation circuit 25, the transmission / reception switching circuit 26, the antenna 27, the timing generation unit 28, and the demodulation circuit 29 The control circuit 2A constitutes a control side communication means.

  The lighting control device 2 having the above-described configuration multiplexes / packetizes a packet that becomes identification code setting information from the free ID and identification ID set in the identification ID encryption information setting unit 22 after power supply is started. The packet is generated by the unit 23, accumulated in the memory circuit 24, and read out from the memory circuit 24 according to the timing generated by the timing generation unit 28. The packet is modulated by the modulation circuit 25 and transmitted. After the identification ID is set in the lighting device 3, a packet that becomes dimming illumination command information is multiplexed from the dimming / toning control data generation unit 21 and the identification ID. Generated by the packetizing unit 23, accumulated in the memory circuit 24, and read out from the memory circuit 24 according to the timing generated by the timing generating unit 28, modulated by the modulation circuit 25 and transmitted.

  FIG. 4 is a configuration diagram of the illumination device 3. First, the structure of FIG. FIG. 4A shows a configuration of the lighting device 3 capable of only dimming. The illumination device 3 includes various information setting units 31, an antenna 32, a transmission / reception switching circuit 33, a demodulation circuit 34, a dimming circuit 35, a light emitting unit 36, a delay circuit 37, a modulation circuit 38, It has.

  Various information setting units 31 as an identification code storage unit and an initial identification code setting unit have an identification code storage unit such as a memory in which an identification ID set from the illumination control device 2 is stored. The various information setting unit 31 is also set with an encryption key and the like, and the manufacturing number information is set similarly to the identification ID encryption information setting unit 22. The production number information is a unique number assigned when the lighting device 3 is produced. In addition, the various information setting unit 31 is set with a free ID as an initial identification code. As described above, the free ID is an ID that is set in advance in common with the lighting control device 2 and the lighting device 3 regardless of train formation and the like, and is set at the time of manufacture. The free ID is set in advance by a dip switch or the like, similarly to the illumination control device 2.

  The transmission / reception switching circuit 33 switches transmission or reception from the antenna 32. In the case of transmission, the signal modulated by the modulation circuit 38 is output to the antenna 32 and transmitted to the illumination control device 2 or another illumination device 3. In the case of reception, the signal received by the antenna 32 is output to the demodulation circuit 34.

  The demodulation circuit 34 demodulates the signal received by the antenna 32 and decrypts the encryption if it has been encrypted. The light control circuit 35 performs light control based on the light control / color control data acquired from the light control illumination command information demodulated by the demodulation circuit. The light emitting unit 36 is configured by an LED, for example, and the luminance is adjusted (dimmed) by the control of the dimming circuit 35.

  The delay circuit 37 delays the timing of modulation by the modulation circuit 38 in order to adjust the transmission timing for relay transmission of the dimming illumination command information and the identification code setting information demodulated and decoded by the demodulation circuit 34. That is, the delay circuit 37 controls the modulation timing of the modulation circuit 25 as with the timing generation unit 28. Similar to the timing generation unit 28, this timing is performed at a predetermined period (a constant time interval) or at a random period. The modulation circuit 38 encrypts and remodulates the information delayed by the delay circuit 37 and transmits it from the antenna 32.

  Next, the configuration of FIG. 4B will be described. FIG. 4B shows a configuration of the lighting device 3 that can perform light control and color control. FIG. 4A is different from FIG. 4A in that light control circuits 35A and 35B and light emitting portions 36A and 36B are provided.

  Since the configuration shown in FIG. 4B can change the toning, that is, the chromaticity, the dimming circuits 35A and 35B and the light emitting units 36A and 36B correspond to a plurality of colors (two colors in the figure), respectively. Is provided. Then, the chromaticity is changed based on the light control / color control data acquired from the light control illumination command information.

  As is clear from the above description, the antenna 32, the transmission / reception switching circuit 33, the demodulation circuit 34, the delay circuit 37, and the modulation circuit 38 constitute the illumination side communication means.

  The illuminating device 3 configured as described above demodulates identification code setting information by a demodulation circuit from a signal received by the antenna 32 within a predetermined time after power is supplied, and stores and sets the identification ID in various information setting units 31. At the same time, the identification code setting information is modulated again and transmitted from the antenna 32 (relay transmission of the identification code setting information). After the identification ID is set in the various information setting unit 31 (after a predetermined time has elapsed), the dimming lighting command information is demodulated from the signal received by the antenna 32, and the dimming lighting command information that matches the set identification ID Based on the light control / color control data, the light control circuit 35 or the like adjusts the luminance and chromaticity of the light emitting unit to perform light control and color control, and remodulates the light control illumination command information from the antenna 32. Transmit (dimming lighting command information relayed).

  FIG. 5 shows a flowchart of the identification ID setting operation of the illumination control device 2 and the illumination device 3. In the description of FIG. 5, the illumination control device 2 will be described as a parent device, and the illumination device 3 will be described as a child device. FIG. 5 shows an example of the case where there are two lighting devices 3 (the slave unit 1 and the slave unit 2). The slave unit 2 is installed at a position where radio waves do not reach directly from the master unit. It is assumed that information is relayed and received from the base unit. Further, all the counter values used in the subsequent flowcharts are set to the initial value 0.

  First, the operation of the master unit will be described. In the first step SC101 after the power is turned on (after the start of power supply), the free ID set in the identification ID encryption information setting unit 22 is read. In step SSC102, the identification ID encryption information setting unit 22 is set. Read the identification ID. Then, a packet serving as identification code setting information is generated by the multiplexing / packetizing unit 23 and stored in the memory circuit 24.

  Next, in step SC103, a random time is waited (random time wait). In this step, the timing generation unit 28 generates a timing at which the memory circuit 24, the modulation circuit 25, and the like transmit identification code setting information. The random time is, for example, a time randomly generated within a predetermined upper limit and lower limit such as between 0.1 second and 1 second.

  Next, in step SC104, an identification ID (identification code setting information) is transmitted. That is, the identification code setting information is read from the memory circuit 24, modulated by the modulation circuit 25, and transmitted from the antenna 27.

  Next, in step SC105, the counter COUNT in the timing generation unit 28 is incremented. In the subsequent step SC106, if the value of COUNT is larger than 4, the operation is terminated assuming that the setting of the identification ID is completed (step SC107). .

  On the other hand, if the value of COUNT is 4 or less in step SC106, the process returns to step SC103. That is, since the loop of steps SC103 to SC106 is performed five times, the identification code setting information is transmitted five times.

  As described above, the time until the master unit can communicate with the slave units 1 and 2 by the execution of step SR107 is dimming time × 5 (unit: second, for example). Become.

  Next, operation | movement of the subunit | mobile_unit 1 is demonstrated. In the first step SR101 after the power is turned on (after the start of power supply), the demodulation circuit 34 reads the free ID set in the various information setting unit 31.

  Next, in step SR102, it is determined whether or not an identification ID (identification code setting information) has been received. That is, when the demodulating circuit 34 receives the identification code setting information that matches the free ID read in step SR101, it is determined that it has been received. If not received, wait until received.

  Next, in step SR103, a random time is waited (random time wait). In this step, the timing at which the delay circuit 37 outputs the received identification code setting information to the modulation circuit 38 is generated. This random time is a time randomly generated within a predetermined upper limit and lower limit such as between 0.1 second and 1 second as in the case of the parent device.

  Next, in step SR104, an identification ID (identification code setting information) is transmitted. That is, the signal is modulated by the modulation circuit 38 and transmitted from the antenna 32. That is, the identification code setting information is relayed and transmitted by executing this step.

  Next, in step SR105, the counter COUNT in the delay circuit 37 is incremented. In the subsequent step SR106, if the value of COUNT is larger than 4, the received identification ID is set in the various information setting unit 31, and the operation is terminated. (Step SR107). The identification ID may be set in the various information setting unit 31 when the identification ID is received in step SR102. After step S107, communication based on the identification ID (for example, transmission / reception of dimming illumination command information) is performed.

  On the other hand, in step SR106, when the value of COUNT is 4 or less, the process returns to step SR103. That is, since the loop of steps SR103 to SR106 is performed five times, the identification code setting information is relayed and transmitted five times.

  The subunit | mobile_unit 1 receives identification code setting information directly from a main | base station, and sets identification ID. Therefore, the time required for the slave unit 1 to set the identification ID in step SR107 is the master unit's random time (× 1 or more × 5 or less) + its own random time × 5. The reason why the random time of the parent device is x1 or more and x5 or less is because transmission from the parent device cannot always be received once. Further, when the identification ID is set in step SR102, only the random time (× 1 to × 5) of the parent device is set.

  Next, regarding the operation of the child device 2, the child device 2 basically performs the same operation as the child device 1. Therefore, the operations of steps SR201 to SR207 in FIG. 5 are the same as those of SR101 to SR107. The subunit | mobile_unit 2 receives the identification code setting information relay-transmitted to the subunit | mobile_unit 1, and identification ID is set.

  Accordingly, the time required for the slave unit 2 to set the identification ID in step SR207 is the random time of the master unit (× 1 to × 5) + the random time of the slave unit 1 (× 1 to × 5) + its own Random time × 5. When the identification ID is set in step SR202, the random time of the parent device (× 1 or more and × 5 or less) + the random time of the child device 1 (× 1 or more and × 5 or less).

  Thus, the time for which the identification ID is set in the slave unit is different depending on the presence / absence of relay and the number of relays. Of course, since the waiting time per one time is determined at random, even if the number of relays is the same, it may be different time. However, since the free ID is an ID common to all the lighting control devices 2 and the lighting devices 3 to be manufactured, if it takes time to set the identification ID, an erroneous setting due to the identification code setting information of another train formation occurs. Probability increases. Therefore, an upper limit time (for example, 5 seconds after the power is turned on) for setting the identification ID to all the lighting devices 3 in one train formation is set in advance, and the worst predicted value of the number of connected vehicles and the number of relays in the train formation is set. The random range and the number of transmissions of the master unit and the slave unit are set so as to satisfy the upper limit time. Therefore, the upper limit time for setting the identification ID to all the lighting devices 3 in the one train formation is the predetermined time described in the claims. That is, the identification ID is set in the lighting device 3 (provided in the lighting control system 1) connected to the train organization within the predetermined time, and communication using the identification ID is performed after the predetermined time has elapsed. .

  According to the present embodiment, the lighting control device 2 transmits identification IDs to a plurality of lighting devices 3 using free IDs, and the lighting device 3 recognizes the free IDs and extracts and sets the identification IDs. This eliminates the need to manually set the identification ID. Therefore, an identification ID for easily discriminating train formation can be set. Moreover, since the free ID is used only during the period from the start of power feeding until the identification ID is set in the lighting device 3, malfunctions due to communication between different trains can be reduced.

  Moreover, since the illuminating device 3 relays the identification code setting information after a lapse of a random time, the identification ID can be set to the illuminating devices 3 of all the vehicles even in the case of a long knitting. In addition, by setting the time after a random time has elapsed, it is possible to reduce the probability of relay transmission overlapping and causing a malfunction.

  In addition, by transmitting the identification code setting information from the lighting control device 2 a plurality of times, the probability that the identification code setting information is not transmitted to all the lighting devices 3 due to a communication failure or the like is reduced, and the identification ID is reliably transmitted. Can be set to

  In addition, by transmitting the identification code setting information received by the lighting device 3 a plurality of times, the probability that the relay of the received information will not be transmitted to the other lighting devices 3 and the lighting control device 2 due to a communication failure or the like is reduced. Can be relayed to.

(Second Embodiment)
Next, an illumination control device 2 and an illumination device 3 according to a second embodiment of the present invention will be described with reference to FIGS. Note that the same parts as those in the first embodiment described above are denoted by the same reference numerals and description thereof is omitted. FIG. 6 is a flowchart of the setting operation of the illumination control device and the identification ID of the lighting device according to the second embodiment of the present invention. FIG. 7 is a flowchart of an operation for confirming the number of connections, which is performed following the flowchart shown in FIG. FIG. 8 is a flowchart showing the operation of the slave unit when relaying confirmation information according to the second embodiment of the present invention.

  This embodiment has the same configuration as the first embodiment, but the operation is different. Specifically, an operation for checking whether there is an erroneous setting after setting the identification ID is added. If the train is determined, the number of lighting devices 3 (number of connections) installed in one train can be obtained. Therefore, after the identification ID is set, the manufacturing number set in the various information setting units 31 of each lighting device 3 is transmitted to the lighting control device 2 as manufacturing number information. That is, the serial number information becomes the illumination identification code, and the various information setting unit 31 functions as the illumination identification code setting unit. Then, the number of serial number information received by the lighting control device 2 is counted and compared with the number of connections obtained in advance, so that the setting of the identification ID is not set correctly or the wrong setting is set in the lighting device of another organization. Can be detected.

  In the present embodiment, the number of connected lighting devices 3 (number of correct connections) is set in the control circuit 2A. The number of connected devices is the number of all lighting devices 3 controlled by the lighting control device 2. Usually, the number of trains for one train (the number of lighting devices 3 per vehicle x the number of vehicles connected) is set. Note that the number of connected devices may be determined by calculating the number of vehicles connected to the number of lighting devices 3 per vehicle and calculating the number of connected vehicles. Then, the control circuit 2A compares the number of correct connections with the count number of production number information included in confirmation information described later, and determines whether or not to output an alarm.

  FIG. 6 shows a flowchart of the identification ID setting operation of the illumination control device 2 and the illumination device 3. In the flowchart shown in FIG. 6, the operation of each step is the same as in FIG. 5 except that the handset 2 is omitted (FIG. 6 is used to distinguish COUNT shown in FIG. 5 from COUNT 2 and COUNT 3 described later. Then, it is referred to as COUNT1). The flowchart shown in FIG. 6 continues from FIG.

  FIG. 7 is a flowchart of the operation for confirming the number of connections after setting the identification ID. First, the operation of the master unit will be described. In step SC108 advanced from step SC107, the timer value t in the control circuit 2A is started as 0, and in step SC109, the number of correct connections (the number of connected lighting devices 3) set in the control circuit 2A is read.

  Next, in step SC110, a random time is waited (random time wait). In step SC111, the control circuit 2A determines from the signal demodulated by the demodulation circuit 29 whether or not confirmation information including the production number information has been received. This determination is made based on whether or not confirmation information matching the identification ID set in the identification ID encryption information setting unit 22 has been received. If not received, it waits until it is received, and if received, proceeds to step SC112. That is, the confirmation information is information including an identification ID and production number information.

  Next, in step SC112, the control circuit 2A determines whether the serial number information received in step SC111 is received for the first time. By determining in this step, it is possible to prevent the same serial number (that is, the same lighting device 3) from being erroneously counted a plurality of times. Since the same serial number is not assigned, each lighting device 3 can be identified from the lighting control device 2. If it is the first connection number received as a result of the determination in step SC112, in step SC113, the control circuit 2A counts (increments) the number of serial numbers. If the connection number received for the first time is not the result of the determination in step SC112, step SC113 is not executed. That is, among the confirmation information received by the control-side communication means, the number of illumination identification codes that match the unique identification code set in the unique identification code setting unit and are different from each other is counted.

  Next, in step SC114, the control circuit 2A determines whether or not the timer value t exceeds 30 seconds. If it exceeds, the process proceeds to step SC115, and if not, the process returns to step SC110. That is, since the serial number information is received for 30 seconds after the identification ID is set in the lighting device 3, the serial number information received during the 30 seconds is counted. Of course, the timer value t is not limited to 30 seconds, and may be changed as appropriate according to the number of lighting devices 3 installed, a predetermined time for setting the identification ID, and the like.

  Next, in step SC115, the control circuit 2A determines whether or not the production number count value matches the number of correct connections, and if the answer is correct, the control circuit 2A ends. If not, the control circuit 2A issues an alarm in step SC116. As an alarm, for example, a warning by displaying characters or a warning sound is output from a display device or a sound output device provided in or connected to the lighting control device 2 itself, and the identification ID Prompt to reset. In other words, if the correct number of connections does not match, the lighting control device 2 outputs information prompting the resetting of the identification ID (retransmission of the identification code setting information) to a display device, an audio output device, or the like. The resetting can be performed, for example, by turning on the power again.

  Next, operation | movement of the subunit | mobile_unit 1 is demonstrated. In step SR108 advanced from step SR107, the timer value t in the various information setting unit 31 is started as 0, and the manufacturing number set in the various information setting unit 31 is read in step SR109. Then, confirmation information including an identification ID and production number information is generated.

  Next, in step SR110, a random time is waited (random time wait). In this step, the timing at which the delay circuit 37 outputs the confirmation information generated in step SR109 to the modulation circuit 38 is generated. Similar to the first embodiment, this random time is a time randomly generated within a predetermined upper and lower limits such as between 0.1 second and 1 second.

  Next, in step SR111, manufacturing number information (confirmation information) is transmitted. That is, the signal is modulated by the modulation circuit 38 and transmitted from the antenna 32.

  Next, in step SR112, the counter COUNT2 in the delay circuit 37 is incremented. In the subsequent step SR113, when the value of COUNT2 is larger than 4, the process proceeds to step SR114. On the other hand, when the value of COUNT2 is 4 or less, the process returns to step SR110. That is, since the loop of steps SR110 to SR113 is performed five times, the confirmation information is transmitted five times.

  Next, in step SR114, the various information setting unit 31 determines whether or not the timer value t exceeds 5 seconds. If it exceeds, the process ends. If not, the information setting unit 31 waits until it exceeds. That is, the illumination device 3 transmits the confirmation information within 5 seconds after the identification ID is set (after a predetermined time has elapsed). Of course, the timer value t is not limited to 5 seconds, and may be appropriately changed according to the system configuration or the like.

  The slave unit 2 shown in FIG. 5 performs the same operation as that of FIG. Further, the confirmation information is transmitted to the lighting control device 2 by relay transmission from the slave unit as well as the identification code setting information. FIG. 8 shows the operation of the slave when relaying confirmation information. The flowchart of FIG. 8 operates by interruption.

  First, in step SR301, the data received by the demodulation circuit 34 is demodulated and stored in the variable N. The variable N may be assigned to, for example, an internal memory or a register. In step SR302, the demodulation circuit 34 determines whether or not the received data stored in the variable N has been received for the first time. If the received data is not the first received data, the interrupt process is terminated.

  On the other hand, in the case of data received for the first time in step SR302, in step SR303, a random time is waited (wait for random time). Similar to step SR103, this step generates a timing at which the delay circuit 37 outputs the identification code setting information received to the modulation circuit 38.

  Next, in step SR304, the data stored in variable N is transmitted. That is, the signal is modulated by the modulation circuit 38 and transmitted from the antenna 32. That is, the confirmation information is relayed and transmitted by executing this step.

  Next, at step SR305, the counter COUNT3 in the delay circuit 37 is incremented. When the value of COUNT3 is larger than 4 at the subsequent step SR306, the interrupt operation is terminated. On the other hand, in step SR306, when the value of COUNT3 is 4 or less, the process returns to step SR303. That is, since the loop of steps SR303 to SR306 is performed five times, the data (confirmation information) stored in the variable N is relayed and transmitted five times.

  Note that the flowchart of FIG. 8 can also be used to relay identification code setting information. In that case, step SR302 may be deleted.

  Further, the operation for confirming the number of connections according to the flowcharts of FIGS. 7 and 8 is not limited to once after the identification ID is set, and may be performed a plurality of times with a predetermined time interval. By doing so, it is possible to more reliably detect an erroneous setting such as when the number of identification ID setting omissions is the same as the number of erroneously set lighting devices of other organizations.

  According to this embodiment, the total number of the illuminating devices 3 in the train organization can be counted by counting the serial number information in the illuminating control device 2. As a result, for example, when the identification device ID is mistakenly set for the lighting device 3 attached to another train organization, or when the identification ID of another train organization is erroneously set, it is set in advance. Since the number of connected devices does not match, the identification ID can be set again.

  Moreover, since the manufacturing number always given at the time of manufacture of the illuminating device 3 is used as the illumination identification code, the illumination identification code can be a unique number. Therefore, it is possible to prevent erroneous counting.

  In the lighting device 3, the demodulation circuit 34, the delay circuit 37, the modulation circuit 38, and the like control the flowchart. However, a control circuit (not shown) may be separately provided to control the flowchart. .

  In addition, the illumination identification code is not limited to the manufacturing number, and a unique number (code) such as a MAC (Media Access Control) address that allows the illumination control device 2 to identify the illumination device 3 is assigned. Good.

  Further, although the waiting time is set to a random time, it may be set to a predetermined time.

  In the above-described embodiment, radio waves are used as a carrier wave. However, light may be used (optical communication). When the carrier wave is light, the antenna is replaced with an optical system such as a lens.

  Further, the present invention is not limited to the above embodiment. That is, those skilled in the art can implement various modifications in accordance with conventionally known knowledge without departing from the scope of the present invention. Of course, such modifications are included in the scope of the present invention as long as the illumination control system, the illumination control device, and the illumination device of the present invention are configured.
