In order to solve the low-vsage problem of streetlights in daily life, such as low utilization of energy and difficult to control intelligently, this paper puts forward a streetlights monitoring system based on GSM and PLC technology by introducing ant colony algorithm to find an optimal path from the centralized controller to the destination terminal to achieve real-time and intelligent monitoring of streetlights. It describes the overall structure of the monitoring system,hardware and software design, focuses on the street light control terminal design and the realization of ant colony algorithm optimization and analyzes the application of the system. The system is composed of streetlights control terminal, streetlights centralized controller and monitoring center. STC12C2052AD single-chip microcomputer is used as a microprocessor for the streetlights control terminal. It controls the PLC modules KQ130F+to realize communication between streetlight nodes and intelligently controls streetlights based on environment parameters detected by sensors. The control terminal transfers data to the centralized controller though the power line, then, the data is sent to the monitoring center by GSM net. The simulation tests show that ant colony algorithm,based on the connection of the communication link and the different service requirements, can find the optimal power line carrier communication network paths. The system has low-cost, easy operation and energy saving features and meets the needs of street light control.
