The Design Of Solar Road Stud Route Guidance System Based On Beidou Satellite And ZigBee Communication Technology

The solar energy road stud has been widely used in the field of traffic.It is a active flashing warning signs which is clear,eye-catching,brightness adjustable.It can be a good description of the outline of the road if it is laid continuously. It will play a big role especially in foggy weather or night.There are three ways to achieve synchronous flashing control: cable power supply、host control and GPS synchronization.The cable power supply way has a special advantage.All LED studs are connected by a cable and can be powered centrally and all can be control by the system.This way has a excellent performance,but the installation is more complex,and must slotting,embedding and potting etc..Host control way is a kind of wireless solutions,this way can synchronous LED studs within a certain range.The GPS synchronization way to achieve synchronous flashing effect,this way has a good performance and no distance limited but the cost is slightly higher. At the same time GPS is abroad,limited use of permissions.Based on the analysis and investigation of market synchronous LED studs,the design is comprehensive to consider the safety,comfort,reliability,cost,installation and convenient maintenance.This paper presents a design of LED stud guidance system base on Beidou and Zig Bee technology. In this paper, the Beidou satellite navigation and positioning system, which is developed by our country,is used to replace the commonly used GPS system in the market to provide a unified time standard. And then synchronize the time standard to t entire network through the low cost Zig Bee technology.In this way,we don’t need to install a Beidou module for every stud to obtain a uniform time standard,so we can save cost.
