The level of urban illumination supervisory control reflects not only construction levels but also the modernization degrees of the city. Traditional control and maintenance of street lamps is not enough more to modernization need. It is a necessity to design and realize a kind of higher autoimmunization, more credible and efficient long-distance monitoring and control system. The work takes GPRS (General Packet Radio Service) communication and ZigBee networks as the key technologies. It realized the unified control, monitoring and management of urban street lamp system by computers. And the entire Remote Terminal Unit is powered by the solar energy. Through the experiment result, it indicates that one month can save energy about 20%. So, the system has high reliability, strong applicability and can save manpower, reduce expense of electricity and improve management of street lamps in city.
