[0006] In order to solve the above problem, an information processing device according to one embodiment of the present invention is an information processing device having a lighting fixture status confirmation processing unit that confirms the status of a plurality of lighting fixtures, the plurality of lighting fixtures being connected in series by wiring, and the information processing device being connected by the wiring to a lighting fixture at a first end and a lighting fixture at a second end of the plurality of lighting fixtures connected in series, and each of the plurality of lighting fixtures, upon receiving a signal from one side, forwards the signal to the other side, and if the signal received from the one side is a request signal, forwards the request signal to the other side and transmits a response signal to the one side, and the lighting fixture status confirmation processing unit, if it has not received the request signal from the lighting fixture at the second end when sending the request signal to the lighting fixture at the first end, transmits the request signal to the lighting fixture at the second end, and if it has not received a response signal from lighting fixtures in a first portion of the plurality of lighting fixtures when sending the request signal to the lighting fixture at the first end, and has received response signals from all lighting fixtures in the first portion when sending the request signal to the lighting fixture at the second end, determines that there is a break in the wiring.

[0007] The lighting fixture status confirmation processing unit may be configured to determine that there is a break in the wiring between the lighting fixture in the first part that is closest to the first end and the lighting fixture in the first part that is closest to the second end if the number of lighting fixtures in the first part is not zero and the number of lighting fixtures other than the first part is not zero.

[0011] If the lighting fixture status confirmation processing unit does not receive a response signal from a second portion of the lighting fixtures in the first portion when sending the request signal to the lighting fixture at the second end, it may determine that there is a faulty lighting fixture among the multiple lighting fixtures, and the number of lighting fixtures in the second portion may be set to be non-zero.

[0012] The lighting fixture status confirmation processing unit may be configured to determine that the lighting fixture in the first portion that is closest to the first end and the lighting fixture in the second portion that is closest to the second end are faulty.

[0013] The lighting fixture status confirmation processing unit may be configured to determine that a lighting fixture between the lighting fixture in the first portion that is closest to the first end and the lighting fixture in the second portion that is closest to the second end is a lighting fixture that requires confirmation by the user.

[0018] <Control device 100> 1 is a diagram showing a control device 100 according to one embodiment of the present invention. The control device 100 is a device that controls multiple lighting fixtures installed in a tunnel. When there are multiple systems each made up of multiple lighting fixtures and the control device 100 controls the multiple systems, the control device 100 controls the lighting fixtures for each system.

[0019] The control device 100 has a control unit 110, a display unit 120, an input unit 130, a first communication unit 140, and a second communication unit 150. The control unit 110 is an information processing device (computer) that processes information. The display unit 120 is a display device that displays information, such as a display. The input device 130 is an input device that receives information input from a user, such as a touch panel. The first communication unit 140 is a communication device for transmitting and receiving information to and from multiple lighting fixtures installed in the tunnel. The second communication unit 150 is a communication device for transmitting and receiving information to and from a higher-level device installed outside the control device 100 and a weather detection sensor. The weather detection sensor is installed outside the tunnel and detects the weather outside the tunnel.

[0020] 2 is a diagram showing an example of the control unit 110. The control unit 110 has a luminaire control processing unit 111, a luminaire state confirmation processing unit 112, and a display processing unit 113.

[0021] The luminaire control processing unit 111 controls the brightness of multiple (N) luminaires LE(1) to LE(N) installed inside the tunnel using communication via the first communication unit 140. The luminaire control processing unit 111 acquires information about the weather outside the tunnel detected by the weather detection sensor, for example, using communication with the weather detection sensor via the second communication unit 150, and controls the brightness of the multiple luminaires LE(1) to LE(N) based on the acquired weather information. The luminaire control processing unit 111 also controls the brightness of the multiple luminaires LE(1) to LE(N) based on information input via the input unit 130. The luminaire control processing unit 111 also receives information from a higher-level device through communication with the second communication unit 150, and controls the brightness of the multiple luminaires LE(1) to LE(N) based on the received information.

[0022] The luminaire control processing unit 111 selects one control pattern from a plurality of pre-prepared control patterns based on, for example, the weather outside the tunnel detected by a weather detection sensor, information input by the input unit 130, or information from a higher-level device, and controls the brightness of the plurality of luminaires LE(1) to LE(N) based on the selected control pattern. The plurality of control patterns may include, for example, a control pattern suitable for sunny weather, a control pattern suitable for cloudy weather, a control pattern suitable for daytime, a control pattern suitable for nighttime, a control pattern suitable for late-night hours, a control pattern suitable for power outages, a control pattern suitable for private power generation, a control pattern suitable for disaster prevention, and a control pattern that turns on the luminaires at 100%. In this case, the control pattern suitable for sunny weather and the control pattern suitable for cloudy weather may each include multiple control patterns.

[0023] The luminaire control processing unit 111 controls the multiple luminaires LE(1) to LE(N) so that the multiple luminaires LE(1) to LE(N) operate in conjunction with each other. If systems other than the system consisting of the multiple luminaires LE(1) to LE(N) are also controlled by the control device, the luminaire control processing unit 111 controls the luminaires for each system so that the luminaires included in each system operate in conjunction with each other. The luminaire control processing unit 111 may also individually control the multiple luminaires LE(1) to LE(N) based on information input by the input unit 130 or information from a higher-level device.

[0024] The luminaire status confirmation processing unit 112 confirms the status of the multiple luminaires LE(1) to LE(N) installed in the tunnel using communication by the first communication unit 140. At this time, the luminaire status confirmation processing unit 112 transmits a request signal to the multiple luminaires LE(1) to LE(N) requesting them to return a response signal including the status of the luminaire, as will be described in detail below.

[0025] The display processing unit 113 displays on the screen of the display unit 120 a display for the user to check information about the control device 100 and buttons for receiving operations from the user. The information about the control device 100 includes, for example, the state of the luminaires LE(1) to LE(N), the state of the wiring W, the operation history of the luminaires LE(1) to LE(N), and the failure history of the luminaires LE(1) to LE(N), as will be described in detail below.

[0026] <Example of processing by the lighting fixture status confirmation processing unit 112> Within the tunnel, multiple luminaires LE(1) to LE(N) are connected in series (in a daisy chain) by wiring W, as shown in FIG. 3. The multiple luminaires LE(1) to LE(N) are connected in the order LE(1), LE(2), ..., LE(N), and the control device 100 is connected by wiring W to the two luminaires LE(1) and LE(N) at both ends of the multiple luminaires LE(1) to LE(N) connected in series (that is, the control device 100 is connected to the luminaire LE(1) at the first end and the luminaire LE(N) at the second end). The wiring W is capable of transmitting communication signals, and the control device 100 (first communication unit 140) communicates with the multiple luminaires LE(1) to LE(N) via this wiring W.

[0027] The example shown in Figure 3 is an example where N = 4, that is, an example where the control device 100 controls four luminaires LE(1) to LE(4).In the example shown in Figure 3, the four luminaires LE(1) to LE(4) are connected in series in the order of LE(1), LE(2), LE(3), and LE(4), and the control device 100 is connected to the luminaire LE(1) at the first end and the luminaire LE(4) at the second end.

[0028] When checking the status of the multiple luminaires LE(1) to LE(N), the luminaire status check processing unit 112 first transmits a request signal REQ1 to the luminaire LE(1) (the luminaire at the first end). In this embodiment, if each of the multiple luminaires LE(m) (m = 1, 2, ..., N) receives a signal from one side, it forwards the signal to the other side. Furthermore, if each of the multiple luminaires LE(1) to LE(N) (m = 1, 2, ..., N) receives a request signal from one side, it forwards the request signal to the other side and transmits a response signal RES1(m) including information about the status of the luminaire LE(m) to the one side.

[0029] Therefore, when the luminaire LE(1) receives the request signal REQ1, it transfers the request signal REQ1 to the luminaire LE(2) and transmits a response signal RES1(1) containing information about the state of the luminaire LE(1) to the control device 100. When the luminaire LE(2) receives the request signal REQ1, it transfers the request signal REQ1 to the luminaire LE(3) and transmits a response signal RES1(2) containing information about the state of the luminaire LE(2) to the luminaire LE(1), and the luminaire LE(1) transfers this response signal RES1(2) to the control device 100. When the luminaire LE(3) receives the request signal REQ1, it transfers the request signal REQ1 to the luminaire LE(4) and transmits a response signal RES1(3) containing information about the state of the luminaire LE(3) to the luminaire LE(2), the luminaire LE(2) transfers this response signal RES1(3) to the luminaire LE(1), and the luminaire LE(1) transfers this response signal RES1(3) to the control device 100. When the luminaire LE(m) receives the request signal REQ1, it transfers the request signal REQ1 to the luminaire LE(m+1) and transmits a response signal RES1(m) containing information about the state of the luminaire LE(m) to the luminaire LE(m-1), the luminaire LE(m-1) transfers this response signal RES1(m) to the luminaire LE(m-2), and the luminaire LE(1) transfers this response signal RES1(m) to the control device 100. When the luminaire LE(N) (the luminaire at the second end) receives the request signal REQ1, it transfers the request signal REQ1 to the control device 100 and transmits a response signal RES1(N) containing information about the status of the luminaire LE(N) to the luminaire LE(N-1), the luminaire LE(N-1) transfers this response signal RES1(N) to the luminaire LE(N-2), ..., the luminaire LE(1) transfers this response signal RES1(N) to the control device 100.

[0030] Fig. 4 is a diagram illustrating the signal flow in the example shown in Fig. 3. In the example shown in Fig. 4, a request signal REQ1 is transmitted to the luminaire LE(1) (the luminaire at the first end). Upon receiving the request signal REQ1, the luminaire LE(1) transfers the request signal REQ1 to the luminaire LE(2) and transmits a response signal RES1(1) containing information about the state of the luminaire LE(1) to the control device 100. Upon receiving the request signal REQ1, the luminaire LE(2) transfers the request signal REQ1 to the luminaire LE(3) and transmits a response signal RES1(2) containing information about the state of the luminaire LE(2) to the luminaire LE(1), and the luminaire LE(1) transfers this response signal RES1(2) to the control device 100. When the luminaire LE(3) receives the request signal REQ1, it transfers the request signal REQ1 to the luminaire LE(4) and transmits a response signal RES1(3) containing information about the state of the luminaire LE(3) to the luminaire LE(2), the luminaire LE(2) transfers this response signal RES1(3) to the luminaire LE(1), and the luminaire LE(1) transfers this response signal RES1(3) to the control device 100. When the luminaire LE(4) (the second end luminaire) receives the request signal REQ1, it transfers the request signal REQ1 to the control device 100 and transmits a response signal RES1(4) containing information about the state of the luminaire LE(4) to the luminaire LE(3), the luminaire LE(3) transfers this response signal RES1(4) to the luminaire LE(2), the luminaire LE(2) transfers this response signal RES1(4) to the luminaire LE(1), and the luminaire LE(1) transfers this response signal RES1(4) to the control device 100.

[0031] Therefore, if there are no failures in any of the multiple luminaires LE(1) to LE(N) and no breaks in the wiring W, the control device 100 receives the request signal REQ1 transferred by the luminaire LE(N) and receives response signals RES(1) to RES(N) from all of the multiple luminaires LE(1) to LE(N). If the luminaire status confirmation processing unit 112 receives the request signal REQ1 from the luminaire LE(N) at the second end within a predetermined time (timeout time T) after transmitting the response signal REQ1 to the luminaire LE(1) at the first end and receives response signals RES(1) to RES(N) from all of the multiple luminaires LE(1) to LE(N), it determines that all of the multiple luminaires LE(1) to LE(N) are normal and that there are no breaks in the wiring W. The timeout time T is determined appropriately based on the communication speed, the number of luminaires, and the message lengths of the request signal REQ1 and response signals RES1(1) to RES(N).

[0032] The request signal REQ1 may be transmitted by the luminaire status confirmation processor 112 at predetermined time intervals, for example, so that the luminaire status confirmation processor 112 can periodically check the status of the luminaires LE(1) to LE(N).

[0033] (Broken wiring) In the example shown in Fig. 3, if the wiring W between the luminaire LE(2) and the luminaire LE(3) is broken as shown in Fig. 5, the control device 100 can receive response signals RES1(1) and RES1(2) from the luminaires LE(1) and LE(2) within the timeout period T after the request signal REQ1 is transmitted, but the request signal REQ1 from the luminaire LE(2) does not reach the luminaire LE(3), so the control device 100 cannot receive the request signal RES1 from the luminaire LE(4) (the luminaire at the second end), and therefore cannot receive the response signals RES1(3) and RES1(4) from the multiple luminaires LE(3) and LE(4). Therefore, if the request signal RES1 is not received from the luminaire LE(4) (the luminaire at the second end) within the timeout period T after the request signal REQ1 is transmitted, the luminaire state confirmation processing unit 112 transmits a request signal RES2 to the luminaire LE(4) (the luminaire at the second end). At this time, as shown in FIG. 5, the control device 100 can receive response signals RES2(3) and RES2(4) from the luminaires LE(3) and LE(4) before the timeout period T elapses after the request signal REQ2 is transmitted, but since the request signal REQ2 from the luminaire LE(3) does not reach the luminaire LE(2), the control device 100 cannot receive the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end), and therefore cannot receive the response signals RES2(1) and RES2(2) from the luminaires LE(1) and LE(2).

[0034] In the example shown in Figure 3, if the wiring between the luminaire LE(1) (the luminaire at the first end) and the control device 100 is broken, as shown in Figure 6, the request signal REQ1 from the control device 100 will not reach the luminaire LE(1) (the luminaire at the first end), and the control device 100 will not receive the request signal REQ1 from the luminaire LE(4) (the luminaire at the second end) until the timeout time T has elapsed since the request signal REQ1 was sent, and will not receive all of the response signals RES1(1) to RES1(4) from the multiple luminaires LE(1) to LE(4). Furthermore, as shown in FIG. 6, the control device 100 can receive response signals RES2(1) to RES2(4) from all of the multiple luminaires LE(1) to LE(4) within the timeout period T after the request signal REQ2 is transmitted, but the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end) does not reach the control device 100, and therefore the control device 100 cannot receive the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end).

[0035] In the example shown in Figure 3, if the wiring between the luminaire LE(4) (the luminaire at the second end) and the control device 100 is broken, as shown in Figure 7, response signals RES1(1) to RES1(4) can be received from all of the multiple luminaires LE(1) to LE(4) within the timeout period T after the request signal REQ1 is sent, but the request signal REQ1 from the luminaire LE(4) (the luminaire at the second end) does not reach the control device 100, and therefore the request signal REQ1 from the luminaire LE(4) (the luminaire at the second end) cannot be received. Also, as shown in FIG. 7, the request signal REQ2 from the control device 100 does not reach the luminaire LE(4) (the luminaire at the second end), so the control device 100 is unable to receive the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end) until the timeout period T has elapsed since the request signal REQ2 was sent, and is therefore unable to receive all of the response signals RES2(1) to RES2(4) from the multiple luminaires LE(1) to LE(4).

[0036] Therefore, if the lighting fixture status confirmation processing unit 112 does not receive a request signal from the lighting fixture at the second end when it sends a request signal to the lighting fixture at the first end, it sends the request signal to the lighting fixture at the second end, and if it does not receive a response signal from some (the first part) of the multiple lighting fixtures when it sends the request signal to the lighting fixture at the first end, and if it receives a response signal from all of the lighting fixtures in the first part when it sends the request signal to the lighting fixture at the second end, it determines that all of the multiple lighting fixtures are normal and that there is a break in the wiring.

[0037] In the example shown in Fig. 5, the lamps in the first portion are lamps LE(3) and LE(4), and the lamps outside the first portion are lamps LE(1) and LE(2). The wiring between lamp LE(3), which is the lamp in the first portion closest to the first end, and lamp LE(2), which is the lamp in the other portion closest to the second end, is broken.

[0038] Therefore, if the number of lamps in the first part is not zero and the number of lamps other than the first part is not zero, the lamp status confirmation processing unit 112 determines that the wiring between the lamp closest to the first end among the lamps in the first part and the lamp closest to the second end among the lamps in the first part is broken.

[0039] 6, the luminaires in the first portion are luminaires LE(1) to LE(4), and the number of luminaires other than the first portion is zero. The wiring between the control device 100 (control unit 110) and luminaire LE(1) (the luminaire at the first end) is broken.

[0040] Therefore, if the number of luminaires other than those in the first portion is zero, the luminaire state confirmation processing unit 112 determines that the wiring between the control device 100 (control unit 110) and the luminaire at the first end is broken.

[0041] 7, the number of luminaires in the first portion is zero, and the luminaires other than the first portion are luminaires LE(1) to LE(4). The wiring between the control device 100 (control unit 110) and luminaire LE(4) (the luminaire at the second end) is broken.

[0042] Therefore, if the number of luminaires in the first portion is zero, the luminaire state confirmation processing unit 112 determines that the wiring between the control device 100 (control unit 110) and the luminaire at the second end is broken.

[0043] In this way, in this embodiment, it is possible to check for breaks in the wiring connecting the lighting fixtures and the wiring connecting the lighting fixtures and the control device. In addition, in this embodiment, it is also possible to identify the location of the broken wiring.

[0044] (Fixture malfunction) In the example shown in Fig. 3, if the luminaire LE(3) is faulty, as shown in Fig. 8, the control device 100 can receive response signals RES1(1) and RES1(2) from the luminaires LE(1) and LE(2) until the timeout period T has elapsed since the request signal REQ1 was transmitted, but cannot receive the request signal RES1 from the luminaire LE(4) (the luminaire at the second end), and therefore cannot receive the response signals RES1(3) and RES1(4) from the luminaires LE(3) and LE(4). Also, as shown in Fig. 8, the control device 100 can receive the response signal RES2(4) from the luminaire LE(4) until the timeout period T has elapsed since the request signal REQ2 was transmitted, but cannot receive the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end), and therefore cannot receive the response signals RES2(1), RES2(2), and RES2(3) from the luminaires LE(1), LE(2), and LE(3).

[0045] Also, in the example shown in Figure 3, if the luminaires LE(2) and LE(3) are faulty, as shown in Figure 9, the control device 100 can receive the response signal RES1(1) from the luminaire LE(1) until the timeout period T has elapsed since the request signal REQ1 was sent, but cannot receive the request signal REQ1 from the luminaire LE(4) (the luminaire at the second end), and cannot receive the response signals RES1(2), RES1(3), and RES1(4) from the luminaires LE(2), LE(3), and LE(4). Furthermore, as shown in FIG. 9, the control device 100 can receive a response signal RES2(4) from the luminaire LE(4) until the timeout period T has elapsed since the request signal REQ2 was transmitted, but cannot receive the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end), and cannot receive the response signals RES2(1), RES2(2), and RES2(3) from the multiple luminaires LE(1), LE(2), and LE(3).

[0046] 3, if the luminaires LE(1) and LE(3) are faulty, the control device 100 will not receive the request signal REQ1 from the luminaire LE(4) (the second end luminaire) until the timeout period T has elapsed since the request signal REQ1 was transmitted, and will not receive all of the response signals RES1(1) to RES1(4) from the multiple luminaires LE(1) to LE(4). Furthermore, as shown in FIG. 10, the control device 100 will receive the response signal RES2(4) from the luminaire LE(4) until the timeout period T has elapsed since the request signal REQ2 was transmitted, but will not receive the request signal REQ2 from the luminaire LE(1) (the first end luminaire), and will not receive the response signals RES2(1), RES2(2), and RES2(3) from the luminaires LE(1), LE(2), and LE(3).

[0047] Therefore, in this embodiment, if the luminaire status confirmation processing unit 112 does not receive a response signal from a portion (first portion) of the plurality of luminaires LE(1) to LE(N) when it transmits a request signal REQ1 to the luminaire LE(1) (the luminaire at the first end), and if it does not receive a response signal from a portion (second portion) of the luminaires in the first portion when it transmits a request signal REQ2 to the luminaire LE(N) (the luminaire at the second end), it determines that there is a faulty luminaire among the plurality of luminaires LE(1) to LE(N). Here, the number of luminaires in the second portion is not zero. In addition, in this case, the luminaire status confirmation processing unit 112 determines that the luminaire closest to the first end among the luminaires in the first portion and the luminaire closest to the second end among the luminaires in the second portion are faulty.

[0048] In the example shown in Figure 8, luminaires LE(3) and LE(4) are luminaires in the first part, luminaire LE(3) is a luminaire in the second part, and the faulty luminaire LE(3) is the luminaire closest to the first end among the luminaires in the first part and the luminaire closest to the second end among the luminaires in the second part.

[0049] In the example shown in Figure 9, luminaires LE(2), LE(3), and LE(4) are luminaires in the first part, luminaires LE(2) and LE(3) are luminaires in the second part, the faulty luminaire LE(2) is the luminaire closest to the first end of the first part, and the faulty luminaire LE(3) is the luminaire closest to the second end of the second part.

[0050] In the example shown in Figure 10, luminaires LE(1), LE(2), LE(3), and LE(4) are luminaires in the first part, luminaires LE(1), LE(2), and LE(3) are luminaires in the second part, the faulty luminaire LE(1) is the luminaire closest to the first end of the first part, and the faulty luminaire LE(3) is the luminaire closest to the second end of the second part.

[0051] In the example shown in Fig. 3, if the luminaires LE(1), LE(2), and LE(3) are faulty as shown in Fig. 11, the control device 100 cannot receive the request signal REQ1 from the luminaire LE(4) (the luminaire at the second end) and cannot receive all of the response signals RES1(1) to RES1(4) from the plurality of luminaires LE(1) to LE(4) until the timeout period T has elapsed since the request signal REQ1 was transmitted, as in the example shown in Fig. 10. Also, as shown in Fig. 11, the control device 100 can receive the response signal RES2(4) from the luminaire LE(4) until the timeout period T has elapsed since the request signal REQ2 was transmitted, but cannot receive the request signal REQ2 from the luminaire LE(1) (the luminaire at the first end) and cannot receive the response signals RES2(1), RES2(2), and RES2(3) from the luminaires LE(1), LE(2), and LE(3).

[0052] In other words, when the luminaires LE(1) and LE(3) are malfunctioning, the luminaire status confirmation processing unit 112 cannot determine whether the luminaire LE(2) is in a normal state, as in the example shown in Fig. 10, or whether the luminaire LE(2) is in a malfunctioning state, as in the example shown in Fig. 11, simply by transmitting and receiving the request signal and receiving the response signal as described above. However, since there is a possibility that the luminaire LE(2) is malfunctioning, the user needs to check the status of the luminaire LE(2). Therefore, in such a case, the control device 100 should notify the user that the luminaire LE(2) is a luminaire that requires user confirmation.

[0053] Therefore, the luminaire state confirmation processing unit 112 may determine that the luminaires between the luminaire closest to the first end among the luminaires in the first portion and the luminaire closest to the second end among the luminaires in the second portion are luminaires that require confirmation. In the example shown in Figures 10 and 11, the luminaire LE(2) is the luminaire between the luminaire closest to the first end among the luminaires in the first portion (luminaire LE(1)) and the luminaire closest to the second end among the luminaires in the second portion (luminaire LE(3)).

[0054] (ID not assigned) An ID number is assigned to each of the multiple luminaires LE(1) to LE(N). The ID numbers are assigned in order from the first end luminaire among the multiple luminaires LE(1) to LE(N) connected in series. Therefore, in the example shown in FIG. 3, ID number 1 is assigned to luminaire LE(1), ID number 2 is assigned to luminaire LE(2), ID number 3 is assigned to luminaire LE(3), and ID number 4 is assigned to luminaire LE(4).

[0055] If there are luminaires among the multiple luminaires LE(1) to LE(N) that have not been assigned an ID, as shown in FIG. 12, the control device 100 can receive a request signal REQ1 from the luminaire LE(4) (the luminaire at the second end) until the timeout period T has elapsed since the request signal REQ1 was transmitted, but cannot receive a response signal from a luminaire that has not been assigned an ID (in the example shown in FIG. 12, luminaire LE(2)). Also, in this case, as shown in FIG. 12, the control device 100 can receive a request signal REQ2 from the luminaire LE(1) (the luminaire at the first end) until the timeout period T has elapsed since the request signal REQ2 was transmitted, but cannot receive a response signal from a luminaire that has not been assigned an ID (in the example shown in FIG. 12, luminaire LE(2)).

[0056] Therefore, when the luminaire status confirmation processing unit 112 transmits a request signal REQ1 to the luminaire LE(1) at the first end, if there is a luminaire that has received a request signal REQ1 from the luminaire LE(N) at the second end but has not received a response signal from it within the timeout period T since the transmission of the request signal REQ1, it may determine that there is a luminaire that has not been assigned an ID. In this case, the luminaire status confirmation processing unit 112 may determine that the luminaire that has not received the response signal has not been assigned an ID.

[0057] Furthermore, when a request signal REQ1 is sent to the luminaire LE(1) at the first end, if there is a luminaire that has received a request signal from the luminaire LE(N) at the second end but has not received a response signal from it, a request signal REQ2 may be sent to the luminaire LE(N) at the second end.Then, if the luminaire state confirmation processing unit 112 has received the request signal REQ2 from the luminaire LE(1) at the first end but has not received a response signal from the luminaire that has not received the response signal from it within the timeout period T since the request signal REQ2 was sent, the luminaire state confirmation processing unit 112 may determine that an ID has not been assigned to the luminaire that has not received the response signal.

[0058] (Processing operation in the lighting fixture state confirmation processing unit 112) Fig. 13 is a diagram showing an example of the processing operation in the lighting fixture state confirmation processing unit 112. The processing operation shown in Fig. 13 is executed, for example, at predetermined time intervals.

[0059] The luminaire state confirmation processing unit 112 transmits a request signal REQ1 to the luminaire L(1) at the first end (step S1301). If a request signal REQ1 is received from the luminaire LE(N) at the second end within the timeout period T after the transmission of the request signal REQ1 (step S1302, YES), the luminaire state confirmation processing unit 112 checks whether response signals have been received from all of the luminaires LE(1) to LE(N) within the timeout period T after the transmission of the request signal REQ1 (step S1303).

[0060] If response signals have been received from all of the plurality of luminaires LE (step S1303, YES), the luminaire state confirmation processing unit 112 determines that all of the plurality of luminaires LE(1) to LE(N) are normal, that there are no breaks in the wiring W, and that the wiring W is normal (step S1304).If there are luminaires from which no response signals have been received (step S1303, NO), the luminaire state confirmation processing unit 112 determines that there are luminaires to which no ID has been assigned (step S1305).

[0061] If the request signal REQ1 has not been received from the luminaire LE(N) at the second end by the time the timeout period T has elapsed since the request signal REQ1 was sent (step S1302, NO), the luminaire status confirmation processing unit 112 sends a request signal REQ2 to the luminaire L(N) at the second end (step S1306), and checks whether it has received a response signal from all of the luminaires in the part (first part) that did not receive a response signal when the request signal REQ1 was sent to the luminaire LE(1) at the first end by the time the timeout period T has elapsed since the request signal REQ2 was sent (step S1307).

[0062] If response signals are received from all of the first portion within the timeout period T after the request signal REQ2 is transmitted (YES in S1307), the luminaire status confirmation processing unit 112 determines that all of the luminaires LE(1) to LE(N) are normal and that there is a break in the wiring (step S1308).If response signals are not received from some (second portion) of the luminaires in the first portion within the timeout period T after the request signal REQ2 is transmitted (NO in step S1307), the luminaire status confirmation processing unit 112 determines that there is a faulty luminaire among the luminaires LE(1) to LE(N) (step S1309).

[0063] <Example of display on display unit 120> The display processing unit 113 switches the screen to be displayed on the display unit 120 based on information input from the input unit 130. The screens displayed on the display unit 120 include, for example, a comprehensive monitoring screen which is the first screen, a monitoring screen which displays the individual control contents and status of the luminaires LE(1) to LE(N) in each system, an individual monitoring screen which displays the individual control contents and status of the luminaires LE(1) to LE(N), a control screen for changing the control contents of the luminaires LE(1) to LE(N) in each system, a communication status screen which displays the communication status of the luminaires LE(1) to LE(N) in each system, a history display screen which displays operation history (e.g., control content change history) and fault history (e.g., failure history of the luminaires LE(1) to LE(N)), a time setting screen for setting the time, a wiring check screen for monitoring the wiring status, a direct / remote confirmation screen for setting disabling control by the input unit 130, and a maintenance screen which displays buttons for moving to the normal status screen, operation screen, history display screen, time setting screen, and direct / remote confirmation screen.

[0064] (Overall monitoring screen) Fig. 14 is a diagram showing an example of a comprehensive monitoring screen. In the example shown in Fig. 14, the words "comprehensive monitoring screen" are displayed in the "screen" column to indicate that the comprehensive monitoring screen is being displayed. For example, as shown in Fig. 14, the comprehensive monitoring screen displays the control details of the luminaires LE(1) to LE(N) by the luminaire control processing unit 111 and the states of the luminaires LE(1) to LE(N) confirmed by the luminaire state confirmation processing unit 112.

[0065] When the control device 100 controls systems other than the system consisting of multiple luminaires LE(1) to LE(N), the luminaire control processing unit 111 displays the control details for each system on the overall monitoring screen. In the example shown in Fig. 14, the control device 100 controls the luminaires of a second system in addition to the first system consisting of multiple luminaires LE(1) to LE(N), and the control details of the first system are displayed in the "first system" column, and the control details of the second system are displayed in the "second system" column. The item names may be something other than "first system" and "second system," and may be set appropriately.

[0066] As described above, the luminaire control processing unit 111 controls the brightness of the multiple luminaires LE(1) to LE(N) based on the weather outside the tunnel detected by the weather detection sensor, information input by the input unit 130, or information from a higher-level device. In the example shown in Fig. 14, the control pattern for control based on the weather outside the tunnel detected by the weather detection sensor is displayed in the "Automatic Control" column, the control pattern for control based on information input by the input unit 130 is displayed in the "Input Control" column, and the control pattern for control based on information from a higher-level device is displayed in the "High-Level Control" column. The item names may be something other than "Automatic Control," "Input Control," and "High-Level Control," and may be set as appropriate.

[0067] In the example shown in FIG. 14, the "Interlocking Display" column indicates whether or not the multiple luminaires LE(1) to LE(N) in each system are controlled to be interlocked. In the example shown in FIG. 14, whether or not they are interlocked is indicated by different colors. In the example shown in FIG. 14, a white circle indicates that they are not interlocked, and a black circle indicates that they are interlocked. In the example shown in FIG. 14, the luminaires in the first system are interlocked, and the luminaires in the second system are not interlocked. The item name may be something other than "Interlocking Display" and may be set as appropriate.

[0068] In the example shown in FIG. 14, the status of the luminaires LE(1) to LE(N) confirmed by the luminaire status confirmation processing unit 112 is displayed in the "Luminaire Status" column. In the example shown in FIG. 14, the status of the luminaires LE(1) to LE(N) is displayed using different colors. In the example shown in FIG. 14, a white circle indicates a normal status, and a black circle indicates a fault status. In the example shown in FIG. 14, the status of the luminaires of the first system is a fault status, and the status of the luminaires of the second system is normal. The item name may be something other than "Luminaire Status" and may be set as appropriate.

[0069] The display processing unit 113 may display the status of the weather detection sensors on the overall monitoring screen. In the example shown in FIG. 14, the status of the weather detection sensors is displayed in the "Sensor Status" column. In the example shown in FIG. 14, the status of the weather detection sensors is displayed using different colors. In the example shown in FIG. 14, a white circle indicates a normal state, and a black circle indicates a fault state. In the example shown in FIG. 14, the status of the weather detection sensor of the first system is a fault state, and the status of the weather detection sensor of the second system is a normal state. The item name may be something other than "Sensor Status" and may be set as appropriate.

[0070] In the example shown in FIG. 14, the "Automatic / Manual" column displays whether the control is automatic (control based on the weather outside the tunnel detected by the weather detection sensor) or manual (control based on information input by the input unit 130 or information from a higher-level device). In the example shown in FIG. 14, the word "automatic" indicates automatic control, and the word "manual" indicates manual control. In the example shown in FIG. 14, it is indicated that the first system is controlled manually, and the second system is controlled automatically. The item name may be something other than "automatic / manual" and may be set appropriately.

[0071] In the example shown in Fig. 14, the "Far / Direct" column displays whether or not the brightness of the plurality of luminaires LE(1) to LE(N) can be controlled by the input unit 130 during manual control. In the example shown in Fig. 14, the word "Direct" is displayed in the "Far / Direct" column, indicating that control by the input unit 130 is possible. The item name may be something other than "Far / Direct" and may be set as appropriate.

[0072] Furthermore, when the input unit 130 is a touch panel, the display processing unit 113 displays buttons BC1 and BC2 on the overall monitoring screen for moving to the monitoring screen, as shown in Fig. 14. In the example shown in Fig. 14, the portions displaying the item names of the systems are buttons, and the words "First System" are displayed on button BC1 for moving to the monitoring screen for the first system, and the words "Second System" are displayed on button BC2 for moving to the monitoring screen for the second system.

[0073] Also, when the input unit 130 is a touch panel, the display processing unit 113 displays, on the overall monitoring screen, a button BM for moving to a maintenance screen and a button BS for moving to a direct / remote confirmation screen, as shown in FIG. 14.

[0074] (Monitoring screen) Fig. 15 is a diagram showing an example of a monitoring screen. When the control device 100 controls lighting fixtures of multiple systems, a monitoring screen exists for each system, and the monitoring screen displays the individual control details and status of the lighting fixtures LE(1) to LE(N) in each system, as shown in Fig. 15. In the example shown in Fig. 15, to indicate that the monitoring screen for the first system is being displayed, the words "Monitoring Screen" are displayed in the "Screen" column, and the words "First System" are displayed in the "System" column.

[0075] In addition, in the example shown in Figure 15, the number "100" is displayed in the "Number of Lamps" column to indicate that the number of lamps is 100, the word "Manual" is displayed in the "Auto / Manual" column to indicate that the lamps in the first system are controlled manually, a black circle is displayed in the "Interlocking Display" column to indicate that the lamps in the first system are controlled in an interlocking manner, and the word "Clear Weather" is displayed in the "Control Pattern" column to indicate that the control pattern of the first system is a control pattern suitable for sunny weather.

[0076] In the example shown in Fig. 15, the first system has 100 luminaires, so the 100 luminaires are divided into five rows, with the status of 20 luminaires displayed in each row. If a system includes 100 or more luminaires, the monitoring screen for that system is divided into multiple pages. If the input unit 130 is a touch panel, the display processing unit 113 displays buttons BA1, BA2, BA3, and BA4 on the monitoring screen for moving to other pages, as shown in Fig. 15.

[0077] Each of the first system luminaires is assigned a luminaire number in addition to an ID number. The luminaire numbers are assigned, for example, in the order in which the luminaires are arranged in the tunnel. In the example shown in FIG. 15 , the first row displays the status of luminaires numbered 1 to 20, the second row displays the status of luminaires numbered 21 to 40, and so on, and the fifth row displays the status of luminaires numbered 81 to 100. In each row, a vertical line is displayed every fifth luminaire to make it easier to understand which circle indicates which status of which luminaire number. In the example shown in FIG. 15 , the vertical line between luminaires 5 and 6 and between luminaires 15 and 16 is a dashed line, and the vertical line between luminaires 10 and 11 is a solid line. The luminaire numbers are assigned, for example, in order starting from the luminaire closest to the entrance of the tunnel.

[0078] In the example shown in Fig. 15, each of the luminaires in the first system is displayed as to whether it is off, under control interlocked with other luminaires (interlocked control), under control not interlocked with other luminaires (individual control), or malfunctioning. In the example shown in Fig. 15, a white circle indicates an off state, a black circle indicates interlocked control, a circle hatched with horizontal lines indicates individual control, and a circle hatched with vertical lines indicates a malfunction. In the example shown in Fig. 15, the luminaire with luminaire number 95 is off, the luminaire with luminaire number 48 is under individual control, and the luminaire with luminaire number 10 is malfunctioning. Malfunctions may be divided into communication abnormalities and malfunctions other than communication abnormalities, and each may be displayed differently.

[0079] When the input unit 130 is a touch panel, the display processing unit 113 displays on the monitoring screen a button BT for moving to the overall monitoring screen, a button BSI for moving to the individual monitoring screen, a button BS for moving to the direct / remote confirmation screen, and a button BO for moving to the control screen, as shown in Fig. 15. When the user presses the individual monitoring screen, a numeric keypad may pop up as shown in Fig. 16, allowing the user to input the luminaire number of the luminaire whose status the user wants to check.

[0080] Furthermore, when the input unit 130 is a touch panel, buttons BA5 and BA6 for moving to monitoring screens of other systems may be displayed on the monitoring screen, as shown in Fig. 15. This makes it possible to move to monitoring screens of other systems without returning to the overall monitoring screen.

[0081] (History display screen) Fig. 17 is a diagram showing an example of a history display screen. The display processing unit 113 displays operation history (for example, change history of control content) and fault history (for example, malfunction history of luminaires LE(1) to LE(N)) on the history display screen, as shown in Fig. 17. In the example shown in Fig. 17, five histories are displayed.

[0082] When the input unit 130 is a touch panel, the display processing unit 113 displays, on the history display screen, a button BH1 for displaying the most recent history, a button BH2 for displaying the oldest history, a button BH3 for displaying multiple history entries immediately before the currently displayed history, and a button BH4 for displaying multiple history entries immediately after the currently displayed history, as shown in Fig. 17. Furthermore, when the input unit 130 is a touch panel, the display processing unit 113 displays, on the history display screen, a button BT for moving to a comprehensive monitoring screen and a button BM for moving to a maintenance screen, as shown in Fig. 17.

[0083] The number of fault histories is small compared to the number of operation histories. Therefore, if the operation histories and fault histories are displayed together, it is difficult to find the desired fault history from the displayed history. Therefore, if the input unit 130 is a touch panel, the display processing unit 113 may display a button BH5 for displaying only the operation histories and a button BH6 for displaying only the fault histories, as shown in FIG. 17.

[0084] (Wiring check screen) 18 to 21 are diagrams showing examples of the wiring check screen. When the control device 100 controls multiple systems, a wiring check screen is provided for each system, and the individual status of the luminaires LE(1) to LE(N) in each system is displayed on the wiring check screen, as shown in FIGS. 18 to 21. While the monitoring screen shown in FIG. 15 displays the individual status of the luminaires LE(1) to LE(N) in order of luminaire number, the wiring check screen displays the individual status of the luminaires LE(1) to LE(N) in order of ID number. Therefore, on the wiring check screen, it is possible to check which part of the multiple luminaires LE(1) to LE(N) connected in series has a malfunction. The examples shown in FIGS. 18 to 21 are examples of wiring check screens when the first system is composed of the four luminaires LE(1) to LE(4) shown in FIG. 3.

[0085] 18 to 21, the words "Wiring Check Screen" are displayed in the "Screen" column and the words "First System" are displayed in the "System" column to indicate that the wiring check screen for the first system is being displayed. Also, in the examples shown in Figs. 18 to 21, the number "4" is displayed in the "Number of Fixtures" column to indicate that the number of fixtures in the first system is four, the word "Manual" is displayed in the "Auto / Manual" column to indicate that the fixtures in the first system are being controlled by manual control, a black circle is displayed in the "Interlocking Display" column to indicate that the fixtures in the first system are being controlled by interlocking, and the word "Clear Weather" is displayed in the "Control Content" column to indicate that the control pattern for the first system is a control pattern suitable for sunny weather.

[0086] Fig. 18 is a display example of a wiring check screen for the example shown in Fig. 5. In the example shown in Fig. 5, the wiring W between the lighting fixtures LE(2) and LE(3) is broken. To indicate that the wiring W between the lighting fixtures LE(2) and LE(3) requires user inspection, in the example shown in Fig. 18, the lighting fixtures LE(2) and LE(3) are not malfunctioning, but are indicated by black circles as being malfunctioning. The lighting fixtures LE(1) and LE(2), which are not malfunctioning and do not require user inspection, are indicated by white circles as being malfunctioning.

[0087] Fig. 19 is a display example of a wiring check screen for the example shown in Fig. 6. In the example shown in Fig. 6, the wiring W between the luminaire LE(1) and the control device 100 is broken. In the example shown in Fig. 19, to indicate that the wiring between the luminaire LE(1) and the control device 100 needs to be checked by the user, the luminaire LE(1) is not broken, but is indicated by a black circle as being broken. The luminaires LE(2), LE(3), and LE(4), which are not broken and do not need to be checked by the user, are indicated by white circles as being not broken.

[0088] Fig. 20 is a display example of the wiring check screen for the example shown in Fig. 8. In the example shown in Fig. 8, the lamp LE(3) is faulty. To indicate that the lamp LE(3) is faulty, in the example shown in Fig. 20, the lamp LE(3) is indicated by a black circle as being faulty, while the lamps LE(1), LE(2), and LE(4), which are not faulty and do not require user confirmation, are indicated by white circles as being not faulty.

[0089] Fig. 21 is an example of a wiring check screen display for the example shown in Fig. 10. In the example shown in Fig. 10, luminaires LE(1) and LE(3) are faulty. To indicate that luminaire LE(3) is faulty, in the example shown in Fig. 21, luminaires LE(1) and LE(3) are indicated by black circles as faulty, and luminaire LE(2), which requires user confirmation, is also indicated by a black circle as faulty. In the example shown in Fig. 21, luminaire LE(4), which is not faulty and does not require user confirmation, is indicated by a white circle as not faulty.

[0090] In the example shown in FIGS. 18 to 21, 100 luminaires are divided into five rows, and each row can display the status of 20 luminaires. When a system includes 100 or more luminaires, the wiring check screen for that system is divided into multiple pages. If the input unit 130 is a touch panel, the display processing unit 113 may display buttons BB1, BB2, BB3, and BB4 on the wiring check screen for moving to other pages, as shown in FIGS. 18 to 21. If the input unit 130 is a touch panel, the display processing unit 113 may display buttons BT for moving to a comprehensive monitoring screen, a button BM for moving to a maintenance screen, and a button BS for moving to a direct / remote confirmation screen, as shown in FIGS. 18 to 21. Furthermore, if the input unit 130 is a touch panel, the wiring check screen may display buttons BB5 and BB6 for moving to a wiring check screen for another system.

[0091] The present invention has been described above in terms of preferred embodiments thereof. While the present invention has been described herein with reference to specific examples, various modifications and variations can be made to these examples without departing from the spirit and scope of the present invention as set forth in the claims.
