Solar traffic lights are powered by solar panels, which are quick to install and easy to move. It is suitable for newly built, traffic flow and urgent need for new traffic signal command junctions to meet the needs of emergency power outages, power cuts and other emergencies. The following is how Sunotech will explain the working principle of solar traffic lights.
The solar traffic signal solar panel generates electricity by sunlight, and the battery is charged by the controller. The controller has anti-reverse connection, anti-back charge, anti-over-discharge, anti-overcharge, overload and short circuit automatic protection functions, and has automatic identification. Day and night, automatic voltage detection, automatic battery protection, easy installation, no pollution. The battery is discharged by the controller to the components of the signal, the transmitter, the receiver, and the signal lamp. After the signal machine adjusts the preset mode, the signal is sent to the transmitter, and the wireless signal generated by the transmitter is transmitted intermittently. The transmission frequency and intensity are in compliance with the relevant regulations of the National Radio Management Committee, and the cable around the environment is not used. The radio generates interference, and at the same time ensures that the transmitted signal has strong anti-strong magnetic field (high-voltage transmission line, automobile electric spark) interference capability. After receiving the wireless transmission signal, the receiver controls the light source of the signal to realize the operation of the red, yellow and green lights according to the preset mode. When the wireless transmission signal is abnormal, the yellow flash function can be realized.
By means of wireless transmission, the four signal lights of each intersection only need to set the signal and the transmitter in the light pole of one signal light. When the signal of one signal light sends out the wireless signal, the receiver on the four signal lights of the intersection Both can receive the signal and make corresponding changes according to the preset mode, so there is no need to lay cable connections between the poles.
