The signal lamps 1b to 1d and 2b to 2g disposed on the signal pole 4a are shifted to the flashing or extinguished state.

  The wireless unit 38 provided in each of the signal control master unit 3a and the signal control slave unit 3b transmits a lighting signal from the signal control master unit 3a to the signal control slave unit 3b by wireless communication. Based on the received lighting signal, the signal lamps 1b to 1d and 2b to 2g are controlled via the lighting signal line 5 wired in the hollow portion of the signal column 4a. Therefore, since it is not necessary to bridge the lighting signal line 5 between the signal poles 4a, it is possible to simplify the construction and maintenance work at the time of installation and to improve the aesthetics of the city. In addition, you may incorporate the signal control subunit | mobile_unit 3b in each of signal lamp | ramp 1b-1d, 2b-2g, In this case, the electric power lead-in line from the electric power generation part 20 is made to signal lamp | ramp 1b-1d, 2b-2g. Only 7 will be connected.

  Further, the lighting signal line 5 does not go out of the signal column 4a until reaching the height at which the signal lamps 1b to 1d and 2b to 2g are disposed. In other words, it is not necessary to form the outlet for the lighting signal line 5 up to the height at which the signal lamps 1b to 1d and 2b to 2g are disposed. Therefore, in the signal pole 4a, at a height where the outlet for the lighting signal line 5 is not formed, waterproof processing for preventing water from entering the hollow portion can be easily performed. In the present embodiment, at least the signal is provided. At the height where the control master unit 3a and the signal control slave unit 3b are built, a lead-out port for the lighting signal line 5 is not formed, and waterproof processing is performed to prevent water from entering the hollow portion. As a result, the signal pole 4a functions as a waterproof casing for the signal control master unit 3a and the signal control slave unit 3b, and the signal control master unit 3a and the signal control slave unit 3b are submerged due to floods such as floods and tsunamis. Can be prevented. Furthermore, since the signal control master unit 3a and the signal control slave unit 3b do not require a casing, it is not necessary to manage the casing color and the through holes of various cables in consideration of the surrounding scenery.

  Further, referring to FIG. 3, the wireless unit 38 of the signal control master 3 a has a function of wirelessly communicating information with the console device 21 having a wireless communication function. The console device 21 is an information terminal device such as a tablet-type personal computer that operates under program control. The console device 21 functions as an operation unit for instructing various settings and various operations of the signal control master device 3a, and the signal control master device 3a.

By operating the console device 21, various setting commands and various operation commands are wirelessly transmitted to the signal control master unit 3 a, and the signal control master unit 3 a performs settings corresponding to the received various setting commands and various operation commands. Perform the action. Further, the signal control master device 3a wirelessly transmits the control status of the signal lamps 1a to 1d and 2a to 2h and the log information to the console device 21 in response to a request from the console device 21. Thus, in the present embodiment, various settings and various operations of the signal control master unit 3a can be performed by wireless communication by the console device 21 without opening and closing the maintenance opening provided in the signal pole 4a. Therefore, it is not necessary to open a maintenance opening every time maintenance is performed, and maintenance can be performed even in bad weather, so that maintenance efficiency is improved. In addition, since the degree of intrusion of rainwater and dust into the hollow portion of the signal column 4a in which the signal control master unit 3a and the signal control slave unit 3b are built is drastically reduced, a long life can be realized.

  In addition, assuming that necessary power cannot be secured for some reason, when the traffic signal control device is provided with a power saving mode and the remaining battery level is below a certain level, the signal control master unit 3a and the signal control slave unit 3b may be automatically shifted to a power saving mode such as reducing the light emission amount of the signal lamps 1a to 1d and 2a to 2h. Further, the remaining battery capacity is collected in the signal control master unit 3a by being transmitted from the signal control slave unit 3b to the signal control master unit 3a. The collected battery remaining amount is transmitted from the signal control master 3a to the central device of the traffic control center via the transmission unit 35, and the battery capacity can be monitored by the traffic control center. Thereby, for example, when the remaining battery level is below a certain level, it is possible to alert the traffic control center by sounding an alarm, and to prevent the signal lamp from being extinguished due to battery shortage.
