Timing device of streetlight control box and timing method

The invention discloses a timing device of a streetlight control box and a timing method. The method comprises a GPS signal receiver, a GPS signal processing chip and a singlechip control chip which are sequentially connected with each other. The method comprises the following steps of: receiving a GPS satellite signal; filtering the received signal; processing the filtered signal; converting the signal into a digital signal; storing the digital signal; judging whether the digital signal is an integral point signal; converting the integral point signal into a PPI signal, and writing the PPI signal into a PLC storage unit of a streetlight controller; and judging a non-integral point signal after stopping for N seconds. The invention directly receives a satellite synchronous signal with a GPS global positioning system. The invention only can be arranged in the control box to eliminate a great number of equipment investment cost, eliminates the labor cost when automatically timing, and can ...
