| 摘 要： | 随着各类大型桥梁、水坝工程、高层建筑物的日益增多，建筑及其周边环境的安全监控变得十分重要．虽然已有GPS山体滑坡监控系统、真空激光大坝安全监测系统等设备，但是这些系统大多具有成本过高、安装和使用过于复杂等缺点，一直无法得到广泛的推广应用，因此到目前为止可以实用化的微小位移自动监测系统还是非常缺少。

| Abstract: | With the image monitoring as background, the key techniques related in designing real-time micro displacement monitor and control system based on PC-104 BUS are studied. On the basis of a concrete practical system requirement and modular design method, extracting the targets' characteristic points using the center of gravity method, the preliminary system has been created which can detect 500m away and has the resolution of 1cm. In addition, this system can monitor multi-targets, communicate remotely and adapt to all kinds of weather conditions. |
