Road traffic signal lamp switching control device with radio communication function

The invention relates to a road traffic signal lamp switching control device with a radio communication function, and belongs to the technical field of intelligent management and control of road traffic. According to a current road traffic signal lamp, if a signal machine is powered off, the signal lamp stops working, so that traffic paralysis is caused, and accidents are caused. The solar cell panel and the battery are designed, signal lamp control signals of the signal machine can be received, and the signal lamp can be controlled in real time. When the annunciator is powered off, the solar cell panel and the battery of the device continue to supply power to the signal lamp and continue to perform phase control on the signal lamp, and at the moment, the devices can perform information exchange through radio to realize mutual phase coordination. The device is composed of a solar cell panel, a power supply conversion module, a DC/DC module, a cell power supply management module, a main control module, a radio
