Design of Monitoring Device for Goods Train Based on Zigbee Technology
Design and implementation of system of wireless-monitoring for goods train is based on ZigBee technology. The system is consisted of ZigBee monitoring nodes on-site and handheld display terminal. The JN5139 wireless microprocessor is used as the master controller for ZigBee monitoring nodes, which is produced by JENNIC Ltd. in Britain. ZigBee device nodes automatically form wireless sensor networks, and use door magnetic sensor circuit which has high sensitivity and fast response to monitor the status of the door. The alarm information about the status of the door will be transmitted to the handheld wireless terminal to display and alarm. RFID technology is useful in conditions that mobile and car numbers are arbitrarily setted for freight transport in the process of practical design. Furthermore, modular design is used to facilitate the maintenance of the system and improve the capabilities of real-time, reliability, stability and anti-jamming.
