Standby traffic signal lamp apparatus capable of being automatically started during power failure

Abstract

The invention relates to a standby traffic signal lamp apparatus capable of being automatically started during power failure. The standby traffic signal lamp apparatus comprises a power-off controller, a standby traffic signal lamp main device and standby traffic signal lamp slave devices, wherein the power-off controller is provided with a wireless emission module, which sends non-starting control signals to the standby traffic signal lamp main device when the main power grid is alive, the standby traffic signal lamp main device is arranged in one crossing, the standby traffic signal lamp slave devices are respectively arranged in other crossings, and the standby traffic signal lamp main device is provided with a wireless reception / emission module. The wireless reception / emission module receives the non-starting control signals emitted by the power-off controller, and sends starting or non-starting control signals to the standby traffic signal lamp slave devices. Each of the standby traffic signal lamp slave devices is provided with a wireless reception module which receives the starting or non-starting control signals sent by the standby traffic signal lamp main device. The problem that standby signal starting that has to be done on-site by workers takes longer time can be solved.

Description

technical field [0001] The invention relates to a backup traffic signal lamp device, in particular to a backup traffic signal lamp device which can be started automatically when power failure occurs. Background technique [0002] In the prior art, when there is a power failure, the traffic lights at the crossing will fail to work due to a power failure, and lose the corresponding function of commanding traffic, resulting in traffic jams and even accidents. At present, traffic emergency vehicles are mainly used to transport spare temporary traffic lights (mostly hand-push spare signal lights) to the scene for use. However, this solution has two outstanding problems: one is that the transportation takes a certain amount of time. During the waiting period, the traffic lacks effective command and management, the problem is not solved in time, and problems are prone to occur, and the transportation needs to consume a certain amount of time. Manpower and material resources; the 2...
