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...
Based on existing power line structures of multi-path transmission channel model and taking the measured data of practical low voltage power-line communication channel magnitude of the frequency response within the range form 0.5MHz to 20MHz as samples, The particle swarm optimization algorithm of self-adaptive parameter based on ant colony algorithm (AS-PSO) is applied to the multi-parameter identification...
