山体滑坡给工农业带来极大的危害,每年都要造成大量的经济损失和人员伤亡。但是,山体滑坡是可以监控与预测的。在山体大滑动之前,山体表面的位移值,位移的加速度值和滑坡体地下水位置都会发生明显的变化,本系统则在山体的多个采样点设置位移激光传感器FTM--50与地下水位测控传感器PTJ301,分别测出三者的变化量。同时将数据传递给基于核心芯片CC2430的ZigBee模块,经过ZigBee无线网络传递给远端管理平台,进行数据分析,发出预警信号。
Landslides cause great harm to industry and agriculture and cause a great deal of economic loss and casualties every year. However, landslides can be monitored and predicted. The displacement of the mountain surface, the acceleration value of the displacement and the groundwater level of the landslide will obviously change before the mountain slides. The system sets up the displacement laser sensor FTM - 50 and the groundwater level measurement and control sensor PTJ301, were measured three changes. At the same time the data is passed to the ZigBee module based on the core chip CC2430, transmitted to the remote management platform through the ZigBee wireless network for data analysis and issue of the warning signal.
