Research On Node Communication Method Of Tunnel Energy Saving Lighting Control System Based On ZigBee

With the development of Chinese highway, the highway tunnel is increasing year by year.The phenomenon which is excessive lighting and invalid lighting is very common in practice.So there will be a lot of energy is consumed in the tunnel lighting.The realization of intelligent control of tunnel lamp could help us to build environment-friendly society.Firstly,this paper finished the design of hardware circuit of the device type and the nodes on the basis of Z-Stack.Secondly,the node will be affected by external interference and its communication distance and other factors caused the packet error phenomenon in communication.So we put forward to solve this problem in two aspects of optimization:â‘  In order to reduce the system delay and reduce the load of some nodes, we propose the system network structure optimization.â‘¡ In order to increase the communication distance of nodes,We put forward to optimize the node of the radio frequency circuit.In order to optimize the packet error phenomenon that we take the following measures:â‘  Through the comparison of the simulation results of tree and mesh topology, we found that the network topology can reduce the delay and system load.â‘¡ Through the design of power amplifier and low noise amplifier, we can improve the sensitivity of receiver and transmitter power.Through the optimization of the work, we can effectively enhance the reliability of the system, and reduce the PAE rate.Through the study, we have a preliminary implementation of intelligent tunnel lighting control based on Zigbee nodes, and improve the reliability of the systematic by optimizing work.
