The Research And Design Of Tunnel Lighting Control System Based On Wireless Sensor Network

In recent years, our country highway tunnel construction has made great achievements,demand of energy more and more seriously affect the development of tunnel lighting, themodernization highway operation and management requirements is also more and more highon safety,environmental protection and energy saving.Tunnel lighting costs accounted forthe entire operation and management cost ratio is high, the scientific development of thehighway be restricted badly. In recent years, high power LED technology has greatdevelopment in the field of lighting, combined with the new development of the ZigBeetechnology in recent years, give full play to the characteristics of LED light source light effect,long life, strong control, application in the intelligent dimming system.ZigBee chip itself is an enhanced51single-chip, with short time delay, low powerconsumption, the future development prospects were unanimously optimistic about.Especially in intelligent lighting, industrial control, automotive electronics field applicationmust extensive.Firstly, in this paper, the tunnel lighting is analyzed at home and abroad, and severalkinds of short distance wireless communication technology are compared. Then elaboratedthe design request of tunnel lighting and lighting of common are compared, on the basis of thedesign of the application of ZigBee technology in the tunnel lighting system, give full play tothe characteristics of ZigBee technology with short latency low power interference;comparative analysis of the LED and other common tunnel lighting light source as thecharacteristics of the tunnel lighting source, and study on the energy-saving effect of theapplication of ZigBee technology for tunnel lighting system; design of tunnel lighting systemfor wireless control network based on ZigBee technology, the system uses CC2530as thehardware design of network nodes, and the design of the drive circuit, the hardware designscheme of PWM generation circuit and PC communication circuit of the coordinator network;the router network, terminal nodes data acquisition and transmission process are designed indetail. Finally, set up in the laboratory environment system implementation scheme of thehardware and software.
