摘　　要：我国现有的地震监测系统大多很难准确地进行地震短临预报进而降低损失,而且安装困难、费用高。针对这些问题,研究一种基于三分量地震监测和云服务器的远程实时监控预警系统,它的硬件主要是三分量岩土应力仪,其传感器是三个差分式极距型电容传感器。地震时,固体潮应力会使电容极距有较大改变,导致电容值的急剧变化,然后系统对采集数据分析处理,超出预警值则发出地震预警。经过试运行发现,系统分辨率高,性能稳定,安装成本低。In China, the existing earthquake monitoring systems are mostly difficult to make the accurate short-impending earthquake prediction, the installation is difficult, and the cost is extremely high. Designs a remote real-time monitor and early warning system based on three-compo- nent earthquake monitoring and cloud server, the hardware is a three-compenent geotechnical stress meter, and the sensors are three differ- ential capacitive displacement sensors. If an earthquake happens, earth tide stress makes the polar distance of each capacitor change, which leads to a sharp change of the capacitance value, then, the system analyzes and processes the collected data, and sends out the earth- quake early warning if the data exceeds the warning value. The results show that the system has the advantages of high resolution, stable performance and low installation cost.
