Abstract:
     The invention relates to a method for controlling traffic signal light, which is characterized in that: first initializing, that inputting the traffic operation time setting program and standard time with plane cross road into the host machine and sub machine of signal machine; then readying, making sub machine enter into normal state, based on communication protocol to synchronize the hose machine and the sub machine; then operating normally; the host machine drives the signal light at host machine direction, as well as sending wireless signal, and the sub machine receives wireless signal; when the sub machine receives one correct command, modifying local clock, to synchronize the clocks of sub machine and the host machine to modify the color of signal light of sub machine; if the received signal is not correct, the micro processor of sub machine drives the signal light at the sub machine direction; the invention can avoid cable between host and sub machines, with simple process, high reliability and high interference resistance.
