摘要
针对地质灾害发生后,救灾过程中次生灾害频繁发生的问题,设计实现了基于无线网络技术的在线监测系统。该系统以MSP430为CPU组成监测点,辅以CC2530、ADS1234以及各种传感器,部署于监控区域对雨量、震动、表面位移等信息进行采集、预处理和无线发送等工作;通过基于ARM Cortex-M3的嵌入式系统为控制点与GPRS或卫星连接,将数据处理后传输至控制中心或现场救灾中心;控制中心实现对数据的存储分析并得出预警级别。结果表明,系统实现了稳定可靠的数据传输,运行成本低,报警准确性高,适合监测次生灾害,保障施工区域人员及设备的相对安全。
Because of questions after the geological disasters, secondary disasters occur frequently during the relief effort. An on-line monitoring system that is based on wireless network technology is designed. The system is using MSP430 as its monitoring point, complemented by CC2530 ADS1234 and various sensors. It is mainly used for rainfall, vibration, surface displacement and other information in the monitoring area, then pretreat and send the information via wireless to control point. The control point, which is ARM Cortex-M3-based embedded systems, transports all information to the control center PC or on-site disaster relief center via GPRS or satellite. The control center stores the data and analyses them. The results show that the system achieves a stable and reliable data transfer, low operating costs, high alarm accuracy for monitoring secondary disasters. It can provide a secure environment for personnel and equipment in rescue scene.
