Design Of Intelligent Campuslighting Control System Based On Wireless Transmission Technology

In the report of the 19 th national congress of the communist party of China,it was pointed out that education should be given priority to development,so the construction of smart campus has been paid more and more attention,and the intelligent construction of campus lighting control has been put on the agenda.At present,most of the campus lighting control systems in our country adopt wired connection,which has many disadvantages: high system cost,high power consumption,complex construction,energy waste,and difficult maintenance.Wireless sensor network(WSN)is an emerging network that integrates wireless communication,data acquisition and information processing.Zig Bee technology is one of the most representative emerging technologies in wireless sensor networks,with features of low cost and low power consumption.The application of Zig Bee technology in campus lighting control system is conducive to the realization of intelligent and energy-saving campus lighting control system.This paper mainly USES 4G technology,Zig Bee wireless sensor network technology and information management technology to design a set of solutions to improve the campus lighting control system,the core of which is information management platform and database,network coordinator,lighting controller,sensor.The scheme is divided into two network structures: 4G network and Zig Bee network.Information management platform and network coordinator rely on 4G network for data communication,network coordinator and street controller rely on Zig Bee wireless sensor network for data exchange,so that users can achieve the supervision and control of the entire system through the management platform.The hardware design of the system mainly includes network coordinator and lighting controller,and the software part mainly includes the design of information management platform and database,as well as the control program design of street lamp router and network coordinator.Through the software and hardware design to realize the intelligent operation of the whole system: data were collected according to the data acquisition module,terminal node to control the use of light and intelligent detecting the fault condition of lamplight,and through the routing nodes near the brightness information and its own working state to the coordinator node,the coordinator node through the processing analysis after send corresponding orders.The routing node will collect the information to the management center,which will change the street lamp control scheme after appropriate processing.The communication test of the system network is carried out,and the results show that the wireless network established by Zig Bee technology conforms to the requirements of campus lighting,which demonstrates the feasibility of Zig Bee technology in the design of lighting control system.
