Location System Design Based on Weighted RSSI for High-Speed Railway Landslide Monitoring
There exist such problems as high cost, difficult construction and low automation degree of existing landslide monitoring system. To treat these problems, a high-speed railway landslide monitoring system based on Zigbee wireless network technology is designed. In this system, high-speed railway landslide information is obtained by wireless sensor network location technology. Its monitoring data is transmitted by rail side room to remote monitoring center. According to the characteristics of the landslide, location coordinate system is improved. Plan of the system structure and program based on weighted Received Signal Strength Indicator (RSSI) location algorithm is introduced. The simulation experimental results show that the monitoring system can monitor effectively high-speed railway landslide.
