| In recent years, the wireless transport technology in short distance has become the most amazing one and it is developed in the highest speed, the ZigBee fills the vacant position of the low-rate wireless communications technology,and bring out the best in each other in application. ZigBee is a kind of new wireless technology major in those. It is not popular for its recent appearance, while it is becoming popular and a new hot point of wireless research for its special characters.Basing on the studies of the ZigBee network technology, In text designed the remote meter reading system based on ZigBee and compiled the corresponding software to carry on the related debugging, the analysis and research on system's reliability, real-time and security. In order to reduce the watt consumption of the router, we take the Tree+AODVjr as the router arithmetic to keep the power consumption smaller in founding the star network, takeing ARM S3C2410 as the core when designed the base station,and collect the meter reading data through the base station. Through GPRS/GSM module we achieve the base stations, meter reading data centers and real-time control.besides, a meter-reading system software is designed.Through making the single point to the single point and the star network data transmission experiment, we has obtained the empirical datum. Regarding the agreement characteristic, the system reliability and the power loss situation had the overall assurance, has built the solid foundation for the ZigBee technology's further research and the application.The result of experimentation certificates that scheme brought forward is conscientiously feasible, adopting the ZigBee technology there are several Advantage such as:economy resource, convenient operation, high reliability and easy to manage. Base stations and the system make use of more mature systems of GPRS/GSM network to communicate, it meets real-time to such requirements with low costs. |
