基于紫蜂双重定位的尾矿坝位移监测技术

Monitoring Technology of Tailings Dam Displacement Based on ZigBee Double Location

针对GPS定位系统对于中小型矿山来说过于昂贵的事实,提出了采用基于紫蜂双重定位的尾矿坝位移监测技术。该技术将信号强度定位与传送时间定位有机结合,并对两种定位结果分配不同的权重,使得测量精度可以达到分米级别。该系统的实际造价不到一万元,不仅在精度要求范围内可实现位移的自动化监测,而且大大降低了投入成本。

In view of the fact that GPS positioning system is too expensive for some small and medium-sized mines,a monitoring technology of railings dam displacement based on ZigBee double location was proposed. This displacement monitoring technology organically combines signal strength positioning with the trans- mission time positioning, and distribute different weights between the two, the measurement accuracy of monitoring system the can achieve decimeter level. The actual cost of monitoring system is less than 10000 yuan,it not only can accomplish the automatic monitoring of tailings dam displacement in required range of ac- curacy, but also can greatly reduce the cost.
