SYSTEM FOR CONTROLLING A STATUS OF A STREETLIGHT BASED ON THE WIRELESS SENSOR NETWORK

摘要

A streetlight control system based on a wireless sensor network is provided to effectively solve problems that the probability that communication between a streetlight and a streetlight control server is cutoff increases and much cost incurs for installing, using, and maintaining/repairing communication structures. Sensor node sets(100) are separately installed at each streetlight(11), sense operation states of each corresponding streetlight, generates streetlight sensing data corresponding to sense particulars, and upwardly transmits the generated streetlight sensing data to a streetlight control server(5). A streetlight control relay node(300) is installed around each streetlight(11), communicates with the sensor node sets(100), collects the streetlight sensing data and streetlight state data including whether the streetlight sensing data has an error or not to generate streetlight state report data, converts the generated streetlight state report data into RF data, and upwardly transmits the RF data to the streetlight control server(5) through a WSN(Wireless Sensor Network). Or, the streetlight control relay node(300) receives RF type streetlight control data from the streetlight control server(5), converts it into a format suitable for the sensor node sets(100), and transfers the converted streetlight control data to the sensor node sets(100).
