For intelligent street lamp control system in the presence of complex construction, more power consumption and low intelligence, this paper designed an intelligent street lamp controller achieved by ZigBee network. It use the Doppler detector to obtain the speed of the vehicle and pedestrian, and thus control the lights switch. For the phenomenon of some street lamp appeared to be an isolated during the wireless communication, this paper also proposes an isolated nodes relief algorithm based on node transfer. The result is verified by Mat lab simulation. Through the control and regulation to LED lights, both ensure traffic safety and save manpower and energy.
