Energy-saving control method for traffic signal control system

The invention relates to an energy-saving control method for a traffic signal control system. Compared with the prior art, the defect that the existing traffic signal control system power reduction technology is complex or functionally imperfect is solved. The method comprises the following steps: a power adjustment demand plan is acquired; the initial current value of signal lamps is acquired; a power adjustment signal is sent out; a lamp control module receives the power adjustment signal; a signal machine microcontroller waits for a signal lamp group to cyclically run to next phase X; the current value of the signal lamps after adjustment is acquired; and the power adjustment result is verified. By triggering pulsed switching signals in a combined way, power adjustment of signal lamp equipment by signal control equipment is realized, and energy conservation and emission reduction of the signal control system are realized effectively. 本发明涉及种用于交通信号控制系统的节能控制方法，与现有技术相比解决了交通信号控制系统功率降低技术复杂或功能不够完善的缺陷。本发明包括以下步骤：获取
