Description

  The present invention relates to a tunnel lighting facility installed in a tunnel.

  For example, in road tunnels where automobiles run, slave stations such as lighting devices, ventilation devices, disaster prevention devices, road display panels, etc. are placed in the tunnel and monitored and controlled by control commands from the master station provided outside the tunnel. Has been. In this case, a cable is used for a power supply line that supplies power to the slave station and a control line that transmits and receives monitoring information from the slave station and a control command to the slave station. Therefore, as the number of slave stations installed in the tunnel increases, the number of cables increases, cable installation work and maintenance become complicated, and costs increase.

  Therefore, information between the master station and the slave station is transmitted and received by radio, each disaster prevention board that is the slave station has an identification number, and each slave station ( In some cases, it is possible to individually monitor and control a disaster prevention panel, and to reduce the construction cost by minimizing the number of wires and piping cables in the tunnel (for example, see Patent Document 1).

Also, the slave station device attached to each lighting device detects the normal / abnormal state of the lighting device, and this state data and identification data for identifying the own station are wirelessly transmitted from the terminal slave station device as own station data. There is one that is transmitted through a communication line and monitors the state of a plurality of lighting devices installed in a wide range of locations (see, for example, Patent Document 2). In this Patent Document 2, the data from the slave station device is always received by the slave station device in the next stage and the slave station device in the next stage, and the data of the own station is added to the received data, and the next In addition to relaying and relaying sequentially to the slave station device in the stage, the slave station device data from the previous stage is stored, and the master station device receives the data from the slave station device in the previous stage of the adjacent slave station device.

Thereby, a failure of the lighting device can be easily found, and inspection and maintenance can be easily performed.
JP 2000-99846 A (FIG. 1) Japanese Patent Laying-Open No. 2003-347072 (FIG. 1)

  However, since the thing of Unexamined-Japanese-Patent No. 2000-99846 is intended for a long tunnel, it has laid the leaky waveguide cable for transmitting a radio wave in the tunnel. Must be laid. Therefore, the slave station can be monitored and controlled wirelessly, but the cost for installing the leaky waveguide cable is required.

  In JP-A-2003-347072, which is intended for an illumination device on a highway, and the wireless communication line is assumed to be a space free of obstacles, reflection of radio waves on the tunnel side wall as in a tunnel. There is no consideration for the generation of dead zones due to. That is, when radio is applied to tunnel lighting equipment, radio waves are reflected on the side wall of the tunnel, and a dead zone in which the radio waves do not propagate may occur and cannot be transmitted and received properly.

  An object of the present invention is to provide a tunnel illumination facility capable of wirelessly monitoring and controlling an illuminating device as a slave station without laying a cable even in a long tunnel.

  The tunnel lighting equipment according to the invention of claim 1 includes a plurality of lighting devices arranged in the tunnel; an illumination control device that outputs a control command to each lighting device; and each lighting device provided in the lighting control device. A transmitter / receiver that wirelessly transmits and outputs a control command to the device and receives information from each slave station, and a wireless control command received from the transmitter / receiver of the lighting control device built in each lighting device. A control command to the station is taken in, and a control command to the other slave station is relayed and transmitted to other control devices wirelessly, and at the same time, a transmitter / receiver that wirelessly transmits information of the local station is provided. .

  In the present invention and the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified.

  Tunnel lighting equipment is lighting equipment arranged in, for example, a tunnel on a road on which a car runs or a tunnel on which a railway vehicle runs, and a lighting device that is a slave station is installed in the tunnel and in the vicinity of the tunnel entrance and exit. The lighting device as the slave station operates in accordance with a control command from the lighting control device as the master station installed inside. The lighting control device that is the master station is provided with a transmitter / receiver that outputs a control command wirelessly to at least the lighting device that is the slave station, and the control command from the lighting control device that is the master station is sent to the lighting device that is the slave station. A transceiver for receiving wirelessly is provided.

  For example, the lighting control device that is the master station outputs a control command such as an on / off command or a dimming control command for the lighting device that is the slave station. When receiving a control command such as a wireless turn-on / off command or a dimming control command from the master station, the control device that is the slave station turns on or off the lighting device according to the control command. Then, the control command is relayed to the lighting device that is another child station, and information from each lighting device that is the child station is relayed and transmitted to the lighting control device that is the parent station.

  According to the first aspect of the present invention, since the control command is transmitted wirelessly from the lighting control device as the master station to the lighting device as the slave station, a control line for transmitting the control command to the slave station becomes unnecessary. Therefore, the control line laying work is not required and the cost can be reduced. In addition, since the control command can be transmitted to other slave stations by relaying the slave station, the control command can be appropriately transmitted to all the slave stations even in a long tunnel. Further, since the slave station information can be transmitted to the master station by relaying other slave stations, the master station can obtain information of all the slave stations even in a long tunnel. Furthermore, a control command can be newly transmitted to the slave station based on information obtained from the slave station.

  According to a second aspect of the present invention, there is provided a tunnel lighting facility according to the first aspect of the invention. The transmitter / receiver built in the lighting device uses a dipole antenna having directivity for the transmitter / receiver built in the lighting device. It is characterized by that.

  In the present invention, the transmitter / receiver incorporated in the lighting device uses a dipole antenna having directivity in the longitudinal direction of the tunnel or in the oblique vertical direction of the tunnel. This suppresses the generation of a dead zone due to the reflection of radio waves on the tunnel side wall so that wireless communication can be performed appropriately. Usually, the lighting device as a slave station is sequentially attached toward the road surface along the side wall in the longitudinal direction of the tunnel. For example, the transmitter / receiver built in the lighting device has directivity in the longitudinal direction of the tunnel. It transmits and receives between the illuminating devices arrange | positioned in the longitudinal direction. In addition, the lighting device at the end of the tunnel has directivity in the diagonally up and down direction of the tunnel, and transmits and receives between the lighting devices on the facing tunnel side walls. In addition, even if it is lighting apparatuses other than the edge part of a tunnel, it has directivity in the diagonal up-down direction of a tunnel, and it is also possible to transmit / receive between the lighting apparatuses of the tunnel side wall which faces.

  According to the second aspect of the present invention, the transmitter / receiver built in the lighting device has directivity in the longitudinal direction of the tunnel or in the diagonally up / down direction of the tunnel. Can be reduced.

  According to the present invention, since the control command is transmitted wirelessly from the lighting control device that is the master station to the lighting device that is the slave station, a control line for transmitting the control command to the lighting device that is the slave station becomes unnecessary, and the cost is reduced. Can be reduced. In addition, since it is possible to relay control commands to other slave stations via a lighting device that is a slave station, it is possible to properly transmit control commands to all slave stations even in long tunnels. Can relay other slave stations and transmit them to the master station, so that the lighting control device that is the master station can obtain information on the lighting devices that are all the slave stations even in a long tunnel.

  In addition, since the transmitter / receiver built in the lighting device has directivity in the longitudinal direction of the tunnel or in the diagonally up / down direction of the tunnel, it is possible to reduce the occurrence of a dead zone in which the radio wave is reflected by the tunnel side wall and the radio wave does not propagate. .

Hereinafter, a method of transmission between the master station 11 and the slave station 12 will be described.

  FIGS. 8-12 is a block diagram of an example of the tunnel lighting installation in Example 1 of this invention. In FIG. 8, six first-line slave stations 12a to 12f and six second-line slave stations 12a ′ to 12f ′ are provided to face the tunnel side wall, and a total of twelve slave stations 12 are provided. It is needless to say that the number may be 12 or more or less than 12.

  The master station 11 is provided with a wireless transceiver 16, and the slave stations 12 a to 12 f and 12 a ′ to 12 f ′ are provided with wireless transceivers 15 a to 15 f and 15 a ′ to 15 f ′. The transceivers 15 a to 15 f and 15 a ′ to 15 f ′ are transceivers having directivity in the horizontal direction with respect to the horizontal plane shown in FIG. 4A, and the antenna 19 has directivity in the longitudinal direction of the tunnel 1. It is a transceiver built in the lighting device so as to face. Thereby, wireless communication is performed between transmission and reception in the longitudinal direction of the tunnel 1.

  Then, a control command is transmitted wirelessly from the transceiver 16 of the master station 11 to the transceivers 15a to 15f and 15a 'to 15f' of the slave stations 12a to 12f and 12a 'to 12f'. In addition, although illustration is abbreviate | omitted, the power supply line is laid by the substation 12a-12f and 12a'-12f 'from the master station 11 by the wire.

  For example, when lighting the lighting devices that are the slave stations 12a to 12d arranged in the tunnel, the transmitter / receiver 16 of the lighting control device that is the parent station 11 wirelessly sends a lighting command as a control command to the slave stations 12a to 12f. , 12a ′ to 12f ′. An identification number is assigned to each of the slave stations 12a to 12d, and the master station 11 outputs a lighting command that is a control command together with the identification number.

  First, the control command is given from the transmitter / receiver 16 of the master station 11 to the transmitters / receivers 15a and 15a ′ of the most upstream slave stations 12a and 12a ′ by assigning the identification numbers of the slave stations 12a to 12f and 12a ′ to 12f ′. Send wirelessly. The slave stations 12a and 12a ′ determine whether or not the received signal received from the master station 11 includes its own identification number, and if there is a control command to which the own station identification number is assigned, The control command fetched and given the identification number of the other station is transmitted to the downstream slave stations 12b and 12b ′.

  At that time, the information of the own station is also transmitted to the master station 11. The local station information includes monitoring control information such as lighting / extinguishing status, dimming status, ambient temperature, illuminance, humidity, lighting device voltage and current, lighting time, etc. A number is assigned and transmitted to the master station 11. That is, since each of the slave stations 12a to 12f and 12a 'to 12f' includes the transceivers 15a to 15f, information is transmitted and received between the master station 11 and each of the slave stations 12a to 12f and 12a 'to 12f'. It is also possible to do. In FIG. 8, the fact that arrows are shown in both directions means that.

  As described above, the control instruction is transmitted from the master station 11 to the slave stations 12f and 12f ′ at the most downstream side by relaying the transmitters and receivers 15a to 15f and 15a ′ to 15f ′ of the slave stations 12a to 12e and 12a ′ to 12e ′ sequentially. At the same time, information of each of the slave stations 12a to 12e and 12a 'to 12e' is sequentially transmitted. Then, the slave stations 12d to 12a and 12d 'to 12a' are relayed from the most downstream slave stations 12f and 12f 'to the master station 11 by radio to relay the slave stations 12a to 12f and 12a' to The information of 12f ′ is transmitted. Based on the information from each of the slave stations 12a to 12f and 12a ′ to 12f ′, the master station 11 monitors and controls the failure status including the lifetime prediction of the lighting devices that are the slave stations 12a to 12f and 12a ′ to 12f ′. In addition, dimming control is performed from data obtained from external weather conditions (brightness, illuminance, temperature, humidity, fog, rain, snow, etc.).

  In the above description, the most downstream slave stations 12f and 12f ′ are looped back to transmit the information of each slave station 12a to 12f and 12a ′ to 12f ′ to the master station 11, respectively. As shown in the figure, wireless communication is possible between the most downstream slave stations 12f and 12f ′ using the antenna 19 having directivity shown in FIG. 4B, and the master station 11 passes through the slave stations 12a to 12f, and further the slave station 12f. Information may be wirelessly transmitted to the master station 11 in a loop through “˜12a”. In this case, conversely, it is possible to wirelessly transmit information to the master station 11 from the master station 11 through the slave stations 12a 'to 12f' and further through the slave stations 12f to 12a.

  FIG. 10 is a configuration diagram illustrating another example of the tunnel illumination facility in the first embodiment. The example shown in FIG. 10 has directivity in the left-right direction with respect to the horizontal plane shown in FIG. 4A as transceivers 15a to 15f and 15a ′ to 15f ′ with respect to the example shown in FIG. In place of the transmitter / receiver, a transmitter / receiver having directivity in the vertical direction with respect to the vertical plane shown in FIG. 4B is used, and illumination is performed so that the antenna 19 has directivity in the oblique vertical direction of the tunnel 1. The transmitter / receiver is built in the apparatus. As a result, wireless communication is performed by alternately relaying the first series of transceivers and the second series of transceivers facing the side wall of the tunnel 1. The same elements as those in FIG. 8 are denoted by the same reference numerals, and redundant description is omitted.

  First, the control command is given from the transmitter / receiver 16 of the master station 11 to the transmitters / receivers 15a and 15a ′ of the most upstream slave stations 12a and 12a ′ by assigning the identification numbers of the slave stations 12a to 12f and 12a ′ to 12f ′. Send wirelessly. The slave stations 12a and 12a ′ determine whether or not the received signal received from the master station 11 includes its own identification number, and if there is a control command to which the own station identification number is assigned, The control command fetched and assigned with the identification number of the other station is transmitted to the downstream slave stations 12b ′ and 12b facing the side wall of the tunnel 1, respectively. That is, radio waves are radiated and transmitted on a diagonal line. At that time, the information of the own station is also transmitted to the master station 11.

  In this way, the control instruction is sequentially relayed from the master station 11 to the slave stations 12f, 15b ', 15c', 15d ', 15e of the slave stations 12a, 12b', 12c, 12d ', 12e. , And relays the transceivers 15a ′, 15b, 15c ′, 15d, and 15e ′ of the slave stations 12a ′, 12b, 12c ′, 12d, and 12e ′, and transmits a control command to the slave station 12f that is the most downstream. .

  Then, information on each of the slave stations 12a to 12f and 12a 'to 12f' is transmitted to the master station 11 by radio from the most downstream slave stations 12f 'and 12f via the reverse route. Based on the information from each of the slave stations 12a to 12f and 12a ′ to 12f ′, the master station 11 monitors and controls the failure status including the lifetime prediction of the lighting devices that are the slave stations 12a to 12f and 12a ′ to 12f ′. In addition, dimming control is performed from data obtained from external weather conditions (brightness, illuminance, temperature, humidity, fog, rain, snow, etc.).

  In the above description, the most downstream slave stations 12f and 12f ′ are turned back to transmit the information of each slave station 12a to 12f and 12a ′ to 12f ′ to the master station 11, respectively. Wireless communication is possible between the slave stations 12f and 12f ′ using the antenna 19 having directivity shown in FIG. 4B, and the master station 11 passes through the slave stations 12a, 12b ′, 12c, 12d ′, 12e, and 12f ′. Further, information may be wirelessly transmitted to the master station 11 in a loop through the slave stations 12f, 12e ′, 12d, 12c ′, 12b, and 12a ′. In this case, conversely, the master station 11 passes through the slave stations 12a ′, 12b, 12c ′, 12d, 12e ′, and 12f, and further passes through the slave stations 12f ′, 12e, 12d ′, 12c, 12b ′, and 12a. It is also possible to transmit information to 11 wirelessly.

  FIG. 11 is a configuration diagram illustrating still another example of the tunnel illumination facility in the first embodiment. The example of FIG. 11 is different from the example shown in FIG. 8 in that the first-line slave stations 12a to 12f include the transmitter / receiver 15 having both directivities shown in FIGS. 4 (a) and 4 (b). The second-line slave stations 12a ′ to 12f ′ incorporate the transmitter / receiver 15 having directivity shown in FIG. The same elements as those in FIG. 8 are denoted by the same reference numerals, and redundant description is omitted.

  First, the identification number of the slave stations 12a to 12f and 12a 'to 12f' is assigned to the transmitter / receiver 15a of the most upstream slave station 12a from the transmitter / receiver 16 of the master station 11, and a control command is transmitted wirelessly. The slave station 12a determines whether or not the received signal received from the master station 11 includes the identification number of the own station. If there is a control instruction assigned with the identification number of the own station, the slave station 12a takes in the control instruction. The control command to which the station identification number is given is transmitted to the slave station 12b downstream in the longitudinal direction of the tunnel 1 and the second series slave station 12a ′ facing the side wall of the tunnel 1, respectively. At that time, the information of the own station is also transmitted to the master station 11.

  Similarly, the slave station 12b determines whether or not the received signal received from the slave station 12a includes its own identification number, and if there is a control command to which the own station identification number is assigned, The control command fetched and assigned with the identification number of the other station is transmitted to the slave station 12b downstream in the longitudinal direction of the tunnel 1 and the second series slave station 12a ′ facing the side wall of the tunnel 1, respectively. At that time, the information of the own station is also transmitted to the master station 11. Thereafter, the operations are similarly performed up to the downstream slave stations 12c to 12f.

  As described above, the master station 11 sequentially relays the transmitters / receivers 15a to 15e of the slave stations 12a to 12e to transmit control commands to the downstream station 12f, and the transmitters / receivers 15a to 15f of the slave stations 12a to 12f. Control commands are transmitted from 15f to the second series of slave stations 12a ′ to 12f ′ facing the side wall of the tunnel 1 respectively.

  Then, the second series slave stations 12a ′ to 12f ′ transmit the information of the second series slave stations 12a ′ to 12f ′ to the first series slave stations 12a to 12e. Information of each of the slave stations 12a to 12f and 12a 'to 12f' is transmitted wirelessly from the downstream slave station 12f by the reverse route. Based on the information from each of the slave stations 12a to 12f and 12a ′ to 12f ′, the master station 11 monitors and controls the failure status including the lifetime prediction of the lighting devices that are the slave stations 12a to 12f and 12a ′ to 12f ′. In addition, dimming control is performed from data obtained from external weather conditions (brightness, illuminance, temperature, humidity, fog, rain, snow, etc.).

  FIG. 12 is a configuration diagram illustrating still another example of the tunnel illumination facility in the first embodiment. The example of FIG. 12 is different from the example shown in FIG. 8 in that the first series of slave stations 12a to 12f and the second series of slave stations 12a ′ to 12f ′ are shown in FIGS. 4 (a) and 4 (b). The transmitter / receiver 15 having both directivities is incorporated. The same elements as those in FIG. 8 are denoted by the same reference numerals, and redundant description is omitted.

  First, the identification number of the slave stations 12a to 12f and 12a 'to 12f' is assigned to the transmitter / receiver 15a of the most upstream slave station 12a from the transmitter / receiver 16 of the master station 11, and a control command is transmitted wirelessly. The slave station 12a determines whether or not the received signal received from the master station 11 includes the identification number of the own station. If there is a control instruction assigned with the identification number of the own station, the slave station 12a takes in the control instruction. The control command to which the station identification number is assigned is transmitted to the second series slave station 12 a ′ facing the side wall of the tunnel 1. At that time, the information of the own station is also transmitted to the master station 11.

  The slave station 12a ′ determines whether or not the received signal received from the slave station 12a includes the identification number of the local station. If there is a control command assigned with the identification number of the local station, the control instruction is fetched. The control command to which the identification number of the other station is given is transmitted to the slave station 12b ′ downstream in the longitudinal direction of the tunnel 1. At that time, the information of the own station is also transmitted to the master station 11.

  The slave station 12b ′ determines whether or not the received signal received from the slave station 12a ′ includes the identification number of the local station. If there is a control command assigned with the identification number of the local station, the slave station 12b ′ takes the control command. The control command to which the identification number of the other station is assigned is transmitted to the first-line slave station 12b facing the side wall of the tunnel 1. At that time, the information of the own station is also transmitted to the master station 11. Thereafter, the operations are similarly performed up to the downstream slave stations 12c to 12f.

  Thus, the transmitter / receiver 15a of the slave station 12a of the first series from the master station 11, the transceiver 15a 'of the slave station 12a' of the second series, the transceiver 15b 'of the slave station 12b' of the second series, the first The control command is transmitted to the most downstream slave station 12f by sequentially relaying with the transmitter / receiver 15b of the affiliated slave station 12b. Then, information on each of the slave stations 12a to 12f and 12a 'to 12f' is transmitted to the master station 11 by radio from the most downstream slave station 12f in the reverse route. Based on the information from each of the slave stations 12a to 12f and 12a ′ to 12f ′, the master station 11 monitors and controls the failure status including the lifetime prediction of the lighting devices that are the slave stations 12a to 12f and 12a ′ to 12f ′. In addition, dimming control is performed from data obtained from external weather conditions (brightness, illuminance, temperature, humidity, fog, rain, snow, etc.).

  As described above, according to the first embodiment, transmission / reception is performed while relaying a slave station using a directivity transmitter / receiver. Therefore, a slave station installed in a place where radio waves do not reach directly from the master station 11. The control command can be transmitted to 12 and the information of the slave station 12 can be transmitted to the master station 11. Accordingly, even in a long tunnel, control commands can be appropriately transmitted to all the slave stations 12a to 12f and 12a 'to 12f', and information on all the slave stations 12a to 12f and 12a 'to 12f' is transmitted to the master station. 11, all the slave stations 12 can be appropriately monitored and controlled.

  FIGS. 13-17 is a block diagram of the tunnel lighting installation of Example 2 of this invention. 13 to 17, only the first series provided on the side wall of the tunnel 1 is shown.

  FIG. 13 is a configuration diagram illustrating an example of tunnel lighting equipment according to the second embodiment of the present invention. In the example of FIG. 13, the master station 11 directly communicates with the slave stations 12a to 12d in the first embodiment. Although FIG. 13 shows four slave stations 12a to 12d, it goes without saying that the number of slave stations 12 may be four or more or less than four.

  In FIG. 13, the master station 11 is provided with a wireless transmitter / receiver 16, and each of the slave stations 12a-12d is provided with a wireless transmitter / receiver 15a-15d. The transceivers 15 a to 15 d are transceivers having directivity in the left-right direction with respect to the horizontal plane shown in FIG. 4A, and the inside of the lighting device is set so that the antenna 19 has directivity in the longitudinal direction of the tunnel 1. Is a built-in transmitter / receiver. Thereby, wireless communication is performed between transmission and reception in the longitudinal direction of the tunnel 1.

  A control command is transmitted wirelessly from the transceiver 16 of the master station 11 to the transceivers 15a to 15d of the slave stations 12a to 12d. At that time, the information of the own station is also transmitted to the master station 11. When the slave station 12 is a lighting device, the information of the own station is monitoring control information such as lighting / extinguishing state, dimming state, ambient temperature, illuminance, humidity, voltage and current of the lighting device, lighting time, etc. Then, the information of the own station is given the identification number of the own station and transmitted to the master station 11.

  In the example shown in FIG. 13, since the master station 11 wirelessly transmits a control command to the slave stations 12a to 12d and receives information on the slave stations 12a to 12d, the master station 11 and the slave stations 12a to 12d A control line between them becomes unnecessary. Therefore, the control line laying work is not required and the cost can be reduced.

  FIG. 14 is a configuration diagram illustrating another example of the tunnel lighting facility in the second embodiment, and information on each of the slave stations 12a to 12e is intermittently relayed to the slave station 12 and transmitted to the master station 11 wirelessly. It is a thing. FIG. 14 shows a case where the slave stations 12e and 12d and the slave stations 12b and 12a are bypassed, and the transmitter / receiver 15c of the slave station 12c is relayed and transmitted to the master station 11 wirelessly. 14 shows six slave stations 12a to 12f, it goes without saying that the number of slave stations 12 may be six or more or less than six.

  In FIG. 14, the master station 11 is provided with a wireless transmitter / receiver 16, and the slave stations 12a-12f are provided with wireless transmitters / receivers 15a-15f. The transceivers 15 a to 15 f are transceivers having directivity in the left-right direction with respect to the horizontal plane shown in FIG. 4A, and the antenna 19 has a directivity in the longitudinal direction of the tunnel 1. Is a built-in transmitter / receiver. Thereby, wireless communication is performed between transmission and reception in the longitudinal direction of the tunnel 1.

  The master station 11 sequentially relays the transmitters / receivers 15a to 15f of the slave stations 12a to 12e to transmit the control command to the slave station 12f on the most downstream side, and sequentially transmits information on each of the slave stations 12a to 12e. Then, the slave stations 12e and 12d are bypassed from the most downstream slave station 12f, the transmitter / receiver 15c of the slave station 12c is relayed, the slave stations 12b and 12a are further bypassed, and each child station is wirelessly connected to the master station 11 The information of the stations 12a to 12f is transmitted. The number of the slave stations 12 to be bypassed is within a range where radio waves reach as much as possible.

  Here, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the master station 11 and each of the slave stations 12a to 12f. In FIG. 14, arrows in both directions mean that. Therefore, it is also possible to transmit the information of each of the slave stations 12a to 12f to the master station 11 by sequentially relaying each of the slave stations 12e to 12a as shown in FIG.

  In the example shown in FIG. 14, in addition to the effects of the example shown in FIG. 8, the slave stations 12 e and 12 d and the slave stations 12 b and 12 a are bypassed and the information of each slave station 12 a to 12 e is transmitted to the master station 11. Therefore, the information on the slave stations 12a to 12e can be quickly transmitted to the master station.

  FIG. 15 is a configuration diagram illustrating still another example of the tunnel illumination facility in the second embodiment. In FIG. 15, the transmitter / receiver 16 of the master station 11 assigns the identification number of the slave stations 12a to 12c to the slave station 12a of the first slave station group and transmits the control command wirelessly, and the second slave A control command is transmitted wirelessly by assigning the identification numbers of the slave stations 12d to 12f to the slave station 12d of the station group. The slave stations 12a to 12c in the first slave station group transmit their own station information when relaying the control command. Then, the most downstream slave station 12 c in the first slave station group transmits information on the slave stations 12 a to 12 c to the transceiver 16 of the master station 11.

  Similarly, the slave stations 12d to 12f of the second slave station group transmit their own station information when relaying the control command. Then, the most downstream slave station 12f in the second slave station group relays the slave station 12d and transmits information on the slave stations 12d to 12f to the transceiver 16 of the master station 11.

  Here, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the master station 11 and each of the slave stations 12a to 12f. In FIG. 15, the two-way arrows indicate that. Therefore, it is also possible to transmit the information of the slave stations 12a to 12c of the first slave station group to the master station 11 by sequentially relaying the slave stations 12b and 12a of the first slave station group. Similarly, information of the slave stations 12d to 12f of the second slave station group may be transmitted from the slave station 12d to the master station 11 by sequentially relaying the slave stations 12e and 12d of the second slave station group. Is possible.

  In the example shown in FIG. 15, since the information of each of the slave stations 12a to 12c and the slave stations 12d to 12f can be transmitted to the master station 11 for each slave station group, the information of the slave stations 12a to 12e can be quickly transmitted. Can be sent to the master station.

  FIG. 16 is a configuration diagram illustrating still another example of the tunnel illumination facility in the second embodiment. In FIG. 16, the transmitter / receiver 16 of the master station 11 assigns the identification numbers of the slave stations 12a to 12f to the slave stations 12a of the first slave station group, and transmits a control command wirelessly. The slave station 12a of the first slave station group determines whether or not the received signal received from the master station 11 includes its own identification number, and when there is a control command to which the own station identification number is assigned. The control command is taken in, and among the control commands to which the identification number of the other station is given, the control command for the slave station group of the own station is transmitted to the slave station 12b downstream of the slave station group of the own station. Control commands other than the slave station group of the own station are transmitted to the slave station 12d of the second slave station group downstream. Further, the slave stations 12a to 12c of the first slave station group transmit information of the local station when relaying the control command. Then, the most downstream slave station 12 c in the first slave station group transmits information on the slave stations 12 a to 12 c to the transceiver 16 of the master station 11.

  When the slave station 12d in the second slave station group receives the control command from the slave station 12a in the first slave station group, the slave station group 12d determines whether or not the received signal includes the identification number of the local station. If there is a control command with an identification number assigned to it, the control command is taken in, and among the control commands with the identification number of other stations, the control command for the slave station group of the own station is Transmit to the downstream slave station 12e. Control commands other than the local station group of the local station are judged to have a downstream third mobile station group and are transmitted to the downstream mobile station group. Further, the slave stations 12d to 12f of the second slave station group transmit information on the local station when the control command is relayed. Then, the most downstream slave station 12f in the second slave station group relays the slave station 12d and transmits the information of the slave stations 12d to 12f to the transceiver 16 of the master station 11.

  Here, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the master station 11 and each of the slave stations 12a to 12f. In FIG. 15, the two-way arrows indicate that. Therefore, it is also possible to transmit the information of the slave stations 12a to 12c of the first slave station group to the master station 11 by sequentially relaying the slave stations 12b and 12a of the first slave station group. Similarly, information of the slave stations 12d to 12f of the second slave station group may be transmitted from the slave station 12d to the master station 11 by sequentially relaying the slave stations 12e and 12d of the second slave station group. Is possible.

  In the example shown in FIG. 16, since the information of each of the slave stations 12a to 12c and the slave stations 12d to 12f can be transmitted to the master station 11 for each slave station group, the information of the slave stations 12a to 12e can be quickly transmitted. Can be sent to the master station.

  FIG. 17 is a configuration diagram illustrating still another example of the tunnel illumination facility in the second embodiment. A control command is transmitted from the master station 11 to the most downstream slave station while relaying every other slave station 12, and is returned to the slave station 12 in the direction toward the master station 11 by looping back at the most downstream slave station. Send a control command. Finally, control commands are transmitted to all the slave stations, and information on each of the slave stations 12a to 12f is transmitted to the master station 11.

  In FIG. 17, the master station 11 is provided with a wireless transmitter / receiver 16, and the slave stations 12a to 12f are provided with wireless transmitters / receivers 15a to 15f. First, the transmitter / receiver 16 of the master station 11 gives the identification numbers of the slave stations 12a to 12f to the transmitter / receiver 15a of the most upstream slave station 12a, and transmits a control command wirelessly. The slave station 12a determines whether or not the received signal received from the master station 11 includes its own identification number. If there is a control instruction to which the own station identification number is assigned, the control instruction is taken in and The control command to which the identification number of the other station is given together with the station information is transmitted to the slave station 12c, bypassing the downstream slave station 12b.

  Similarly, a slave station that bypasses one slave station and transmits a control command and slave station information to the most downstream slave station 12f, loops back at the most downstream slave station 12f, and bypasses in the direction of the master station 11 12 is output to the last slave station 12b through the control command and slave station information. Then, the last slave station 12b transmits information on all the slave stations 12a to 12f to the transceiver 16 of the master station.

  Here, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the master station 11 and each of the slave stations 12a to 12f. In FIG. 15, the two-way arrows indicate that. Accordingly, one slave station is bypassed in the reverse direction as described above, and the control command and slave station information are transmitted to the most downstream slave station 12f, and are looped back at the most downstream slave station 12f and bypassed in the direction of the master station 11. It is also possible to relay the slave station 12 and output the control command and slave station information up to the last slave station 12b.

  In the example shown in FIG. 17, the slave station is intermittently relayed and looped back at the most downstream slave station, and the control command is sequentially transmitted to all the slave stations. When relaying the control command, the slave station information is displayed. Since transmission is performed, a control command can be transmitted to a slave station installed in a place where radio waves do not reach directly from the master station 11, and information on the slave station can be transmitted to the master station 11. Therefore, even if it is a long tunnel, the master station 11 can appropriately transmit a control command to all the slave stations 12a to 12f, and can acquire information on the slave stations.

  In addition, since the slave station is intermittently relayed and the control command is sequentially transmitted, the time until the control command reaches the most downstream slave station can be shortened. Accordingly, the lighting / extinguishing and dimming control according to the installation position of the lighting device which is the slave station 12 in the tunnel are made uniform, so that the illuminance in the tunnel is made uniform.

  As described above, according to the second embodiment, since the control command and the slave station information are transmitted from the master station to the slave station wirelessly, the control line between the master station and the slave station is not necessary. Therefore, the control line laying work is not required and the cost can be reduced. In addition, since the control command can be transmitted to other slave stations by relaying the slave station, the control command can be appropriately transmitted to all the slave stations even in a long tunnel. Similarly, since the information of the slave station can be transmitted to the master station by relaying other slave stations, the master station can obtain the information of all the slave stations even in a long tunnel.

  FIG. 18 is a configuration diagram of a tunnel lighting facility according to the third embodiment of the present invention. The third embodiment is different from the second embodiment shown in FIG. 13 in that a transmitter 13 is provided instead of the transmitter / receiver 16 of the master station 11, and reception is performed instead of the transmitter / receivers 15a-15d of the slave stations 12a-12d. It is set as the containers 14a-14d. Although FIG. 18 shows a case where four slave stations 12a to 12d are provided, it goes without saying that the number may be four or more or less than four.

  The master station 11 includes a wireless transmitter 13, and each of the slave stations 12 a to 12 d includes wireless receivers 14 a to 14 d. A control command is transmitted wirelessly from the transmitter 13 of the master station 11 to the receivers 14a to 14d of the slave stations 12a to 12d. In addition, although illustration is abbreviate | omitted, the power wire is laid from the master station 11 to each of the slave stations 12a to 12d by wire.

  For example, when lighting the lighting devices that are the slave stations 12a to 12d arranged in the tunnel, the transmitter 13 of the lighting control device that is the master station 11 wirelessly sends a lighting command as the control command to the slave stations 12a to 12d. Send to. An identification number is assigned to each of the slave stations 12a to 12d, and the master station 11 outputs a lighting command that is a control command together with the identification number. The receivers 14 of the slave stations 12a to 12d receive signals transmitted from the master station 11. Each of the slave stations 12a to 12d determines an identification number included in the received signal. When the identification number is the identification number of the local station, the control instruction is fetched and the content is determined to control the lighting device. In this case, since it is a lighting command, the lighting device is turned on. When the control command is a dimming control command, the dimming of the lighting device is controlled according to the dimming control command.

  According to the third embodiment of the present invention, since the control command is transmitted from the master station 11 to the slave stations 12a to 12d by radio, a control line for transmitting the control command to the slave stations 12a to 12d becomes unnecessary. Therefore, the control line laying work is not required and the cost can be reduced.

  FIGS. 19-22 is a block diagram of the tunnel lighting installation of Example 4 of this invention. In the fourth embodiment, a transmitter / receiver 15 is provided in place of the receiver 14 of the slave station 12 with respect to the third embodiment so that a control command can be relayed to other slave stations. 19 to 22 show the case where six slave stations 12a to 12f are provided, it goes without saying that the number may be six or more or less than six.

  FIG. 19 is a block diagram showing an example of tunnel lighting equipment in the fourth embodiment. A control command is transmitted from the master station 11 sequentially to the slave stations 12f of the slave stations 12a to 12e through the transmitters 15a to 15e. It is what you do. In FIG. 19, the master station 11 is provided with a wireless transmitter 13, and each of the slave stations 12a to 12f is provided with wireless transmitters / receivers 15a to 15f.

  First, the transmitter 13 of the master station 11 assigns the identification numbers of the slave stations 12a to 12f to the transmitter / receiver 15a of the most upstream slave station 12a and transmits a control command wirelessly. In the slave station 12a, it is determined whether or not the received signal received from the master station 11 includes its own identification number. If there is a control command to which the own station identification number is assigned, the control instruction is fetched. The control command to which the identification number of the other station is assigned is transmitted to the downstream slave station 12b.

  Similarly, the slave stations 12b to 12e take in the control command when the identification number of its own station is assigned, and the control command to which the identification number of the other station is assigned is the downstream slave station 12c to 12e. The data is sequentially transmitted to 12f. As described above, the control command from the master station 11 is sequentially transmitted from the most upstream slave station 12a to the most downstream slave station 12f via the transmitters / receivers 15b to 15e of the downstream slave stations 12b to 12e.

  In the above description, the case where the control command is sequentially transmitted from the master station 11 to the slave station 12f has been described. However, since each slave station 12a to 12f includes the transceivers 15a to 15f, each slave station 12a. It is also possible to transmit / receive information between ˜12f. In FIG. 19, the two-way arrows indicate that.

  Here, when any of the slave stations 12a to 12e that sequentially relay the transmission signal from the master station 11 fails and cannot transmit a signal to the downstream slave station, the faulty slave station is bypassed and the next slave station is bypassed. Send a transmission signal to the station. For example, when the slave station 12c does not receive a signal from the slave station 12b, the slave station 12b bypasses the slave station 12c and transmits a signal to the slave station 12d. The detection that the slave station 12c does not receive the signal from the slave station 12b is performed, for example, when the slave station 12b does not receive a response signal from the slave station 12c within a predetermined time after transmitting the signal to the slave station 12c. It is determined that the station 12c has failed.

  In the example illustrated in FIG. 19, since the control commands can be sequentially transmitted to the other slave stations 12 b to 12 f by relaying the transceivers 15 a to 15 e of the slave stations 12 a to 12 e, radio waves do not reach directly from the master station 11. A control command can also be transmitted to the slave station 12 installed in the place. Therefore, even in a long tunnel, the control command can be appropriately transmitted to all the slave stations 12a to 12f.

  FIG. 20 is a block diagram showing another example of tunnel lighting equipment in the fourth embodiment. A control command is transmitted from the master station 11 for each predetermined slave station group, and the slave stations in the slave station group are relayed. The control commands are sequentially transmitted to the downstream slave stations in the station group. In FIG. 20, the master station 11 is provided with a wireless transmitter 13, and each of the slave stations 12a to 12f is provided with wireless transmitters / receivers 15a to 15f. First, the transmitter 13 of the master station 11 assigns the identification numbers of the slave stations 12a to 12c to the slave stations 12a of the first slave station group and transmits the control command wirelessly, and the second slave A control command is transmitted wirelessly by assigning the identification numbers of the slave stations 12d to 12f to the slave station 12d of the station group.

  The slave station 12a of the first slave station group determines whether or not the received signal received from the master station 11 includes its own identification number, and when there is a control command to which the own station identification number is assigned. The control command is fetched, and the control command assigned with the identification number of the other station is transmitted to the downstream slave station 12b. The slave station 12b relays the transmitter / receiver 15a of the slave station 12a to determine whether the received signal received from the master station 11 includes the identification number of the own station, and the control command to which the identification number of the own station is given. If there is, the control command is taken in, and the control command assigned with the identification number of the other station is transmitted to the downstream slave station 12c.

  Similarly, the slave station 12d of the second slave station group determines whether or not the received signal received from the master station 11 includes the identification number of the own station, and the control command to which the identification number of the own station is assigned is issued. In some cases, the control command is fetched, and the control command assigned with the identification number of the other station is transmitted to the downstream slave station 12e. When the slave station 12e relays the slave station 12d and determines whether the received signal received from the master station 11 includes the identification number of the own station, and when there is a control command with the identification number of the own station The control command is fetched, and the control command assigned with the identification number of the other station is transmitted to the downstream slave station 12f.

  In this way, the control command from the master station 11 is received for each slave station group, and relayed sequentially by the slave stations 12 in the slave station group, the control command is sent to the slave stations 12c and 12f in the slave station group. Send. Also in this case, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the slave stations 12a to 12f. In FIG. 20, the two-way arrows indicate that. Further, when one of the slave stations 12 to be sequentially relayed fails and a signal cannot be transmitted to the downstream slave station, the failed slave station is bypassed and the next slave station is bypassed as in the example of FIG. A transmission signal is transmitted to the terminal.

  In the example shown in FIG. 20, a control command is transmitted from the master station 11 for each slave station group, relayed through the slave stations 12 in the slave station group, and sequentially transmitted to other slave stations 12, It is possible to shorten the time until the control command reaches the downstream slave station 12. For example, in the case of the example of FIG. 19, the control command arrives at the most downstream slave station 12f by relaying the five slave stations 12a to 12e, but the example shown in FIG. Then, the slave station 12c in the most downstream of the first slave station group is reached by relaying the two slave stations 12a and 12b, and two slave stations 12f in the downstream of the second slave station group are also connected. Since the slave stations 12d and 12e are relayed to reach, the time until the control command reaches the most downstream slave station 12 can be shortened. Therefore, it is possible to suppress the lighting on / off of the tunnel and the delay of the dimming control due to the installation position of the lighting device as the slave station 12.

  FIG. 21 is a configuration diagram showing another example of the tunnel lighting facility in the fourth embodiment, in which a control command is transmitted from the master station 11 to the most upstream child station group, and any child of the most upstream child station group is shown. The control command is relayed sequentially from the station to the downstream slave station group and transmitted sequentially, and within the slave station group, the slave station in the slave station group is relayed and the control command is sequentially transmitted to the downstream slave station. It is. Note that the number of slave stations in the slave station group is a number within a range where radio waves reach from the master station 11 or the relay slave station of the preceding slave station group.

  In FIG. 21, the master station 11 is provided with a wireless transmitter 13, and each of the slave stations 12a to 12f is provided with wireless transmitters / receivers 15a to 15f. First, the transmitter 13 of the master station 11 assigns the identification numbers of the slave stations 12a to 12f to the slave stations 12a of the first slave station group, and transmits a control command wirelessly.

  The slave station 12a of the first slave station group determines whether or not the received signal received from the master station 11 includes its own identification number, and when there is a control command to which the own station identification number is assigned. The control command is fetched, and the control command for the slave station group of the own station is transmitted to the slave station 12b downstream of the slave station group of the own station among the control commands to which the identification number of the other station is given. Control commands other than the group are transmitted to the slave station 12d of the second slave station group.

  Similarly, the slave station 12d of the second slave station group relays the slave station 12a of the first slave station group to determine whether the received signal received from the master station 11 includes the identification number of the local station. If there is a control command to which the identification number of the own station is assigned, the control command is fetched. Among the control commands to which the identification number of the other station is assigned, the control command of the slave station group of the own station is It transmits to the slave station 12e downstream of the slave station group. When there is a control command other than the slave station group of the own station, it is determined that there is a third slave station group, and further transmitted to the third slave station group downstream.

  In this way, the control command from the master station 11 is received by one of the slave stations in the first slave station group, and sequentially transmitted to the downstream slave station group, and within the slave station group, the slave stations in the slave station group sequentially The control command is transmitted to the most downstream slave station in the slave station group. Also in this case, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the slave stations 12a to 12f. In FIG. 21, the arrows in both directions mean that. Further, when one of the slave stations to be sequentially relayed fails and a signal cannot be transmitted to the downstream slave station, the failed slave station is bypassed to the next slave station as in the example of FIG. A transmission signal is transmitted.

  In the example shown in FIG. 21, since any slave station in the slave station group can be relayed and a control command can be sequentially transmitted to any slave station in the other slave station group, the radio station does not reach directly from the master station 11. A control command can also be transmitted to the slave stations of the installed slave stations. Therefore, even in a long tunnel, the control command can be appropriately transmitted to all the slave stations 12a to 12f. Further, since the slave station 12 in the slave station group is relayed and the control command is sequentially transmitted to the other slave stations 12, the time until the control command reaches the most downstream slave station 12 can be shortened. Therefore, when the slave station 12 is an illumination device, it is possible to suppress the lighting on / off of the tunnel and the delay of the dimming control due to the installation position of the slave station 12.

  FIG. 22 is a block diagram showing still another example of the tunnel lighting facility in the fourth embodiment. A control command is transmitted from the master station 11 to the most downstream slave station while relaying every other slave station 12. The control command is transmitted in the direction of the master station 11 to the slave station 12 that has looped back and skipped at the most downstream slave station, and finally the control command is transmitted to all the slave stations.

  In FIG. 22, the master station 11 is provided with a wireless transmitter 13, and each of the slave stations 12a to 12f is provided with wireless transmitters / receivers 15a to 15f. First, the transmitter 13 of the master station 11 assigns the identification numbers of the slave stations 12a to 12f to the transmitter / receiver 15a of the most upstream slave station 12a and transmits a control command wirelessly. The slave station 12a determines whether or not the received signal received from the master station 11 includes the identification number of the own station. If there is a control instruction assigned with the identification number of the own station, the slave station 12a takes in the control instruction. The control command to which the station identification number is assigned is transmitted to the slave station 12c, bypassing the downstream slave station 12b.

  In the same manner, a control command is transmitted to the most downstream child station 12f by bypassing one child station, and then looped back at the most downstream child station 12f to relay the bypassed child station 12 in the direction of the parent station 11. The control command is output up to the last slave station 12b. Also in this case, since each of the slave stations 12a to 12f includes the transceivers 15a to 15f, information can be transmitted and received between the slave stations 12a to 12f. In FIG. 22, the two-way arrows indicate that. Further, when one of the slave stations 12 to be sequentially relayed fails and a signal cannot be transmitted to the downstream slave station, the failed slave station is bypassed and the next slave station is bypassed as in the example of FIG. A transmission signal is transmitted to the terminal.

  In the example shown in FIG. 22, since the slave station is intermittently relayed and looped back at the most downstream slave station to sequentially transmit the control command to all the slave stations, the location where radio waves do not reach directly from the master station 11 A control command can also be transmitted to a slave station installed in the network. Therefore, even in a long tunnel, the control command can be appropriately transmitted to all the slave stations 12a to 12f.

  In addition, since the slave station is intermittently relayed and the control command is sequentially transmitted, the time until the control command reaches the most downstream slave station can be shortened. Accordingly, the lighting / extinguishing and dimming control according to the installation position of the lighting device which is the slave station 12 in the tunnel are made uniform, so that the illuminance in the tunnel is made uniform.

  According to the fourth embodiment, since the control command is transmitted from the master station to the slave station wirelessly, a control line for transmitting the control command to the slave station is not required, and the cost can be reduced. In addition, since the control command can be transmitted to other slave stations by relaying the slave station, the control command can be appropriately transmitted to all the slave stations even in a long tunnel. In addition, the transmission of control commands can be homogenized.
