An energy-saving control method based on multi-sensor system for solar street lamp

Based on the multi-sensor system, one energy-saving method is provided to control the working period of solar street lamp. The multi-sensor system applies infrared and sound sensors to collect the signal of man body. While the useful signal is recognized, the output power on the load is increased and provides the short-term assistant lighting. This new control method on solar street lamp satisfies the random requirement of lighting in night, realizes the energy saving, and optimizes the distribution of storage batteries. The application of this control method can extend the working period with same storage batteries.
