【摘要】：近年来随着人类改造工程不断的增加，灾害发生的次数明显增加。尤其每年的雨季，地质灾害频繁发生。已经引起了国家的高度重视，治理地质灾害刻不容缓。现有的地质灾害的预防预测方法比较落后，，不能及时的预测地质灾害的发生。因此急需研究一种监测方案，能在灾害发生前及时的通知当地群众，确保人民的生命安全。特别是如何对同一地区近距离的多个地方进行监测成为一个难题。根据现有的无线传感技术，对同一地区近距离的多个地方的监测成为可能，可以将仪器监测的结果及时上传监控中心。ZigBee技术走入了我们的视线，它具有低功耗、自动组网、成本低的特点，也适合于地质灾害监测。本课题主要是对同一地区近距离多个地质灾害易发区建立一种地质灾害监测网，使远处的管理人员可以了解现场状况。地质灾害监测网包括三大部分。传感器节点负责采集数据，并和下一级节点的传过来的数据相融合，向上传送到它的父节点，最终把数据以接力的方式传输到基站节点。地质灾害传感网的近距离无线传输模块采用TI的CC2530。基站节点负责将所有采集的数据通过GPRS模块传输到服务器，管理人员通过传输过来的监测数据预测是否有地质灾害要发生。如果灾害要发生，可以及时通知当地群众撤离或采取措施处理掉险情，使群众的安全得到保障。搭建起实验平台，进行各种模拟实验。从采集的数据可以看出本方案的可行性和正确性。本方案能够连续持续运行，证明系统的稳定性。从能量角度考虑，只有采集数据的时候才处于正常工作状态，其余时间处在低功耗模式，非常省电。
[Abstract]:In recent years, with the continuous increase of human reconstruction projects, the number of disasters has increased significantly. Especially in the rainy season every year, geological disasters occur frequently. Has caused the country's high attention, the management geological disaster is urgent. The existing methods of geological hazard prevention and prediction are backward and unable to predict the occurrence of geological disaster in time. Therefore, it is urgent to study a monitoring scheme which can inform the local people in time before the disaster and ensure the safety of the people. In particular, how to monitor multiple places close to the same area has become a difficult problem. According to the existing wireless sensor technology, it is possible to monitor multiple places in the same area at close range. The results of instrument monitoring can be uploaded to the monitoring center in time. ZigBee technology comes into our sight. It has the characteristics of low power consumption, automatic networking and low cost. It is also suitable for geological hazard monitoring. This project is mainly to establish a geological hazard monitoring network for close range and multiple geological hazard prone areas in the same area, so that the remote managers can understand the situation of the field. Geological hazard monitoring network consists of three parts. The sensor node is responsible for collecting data and merging with the data transmitted from the next node to its parent node. Finally the data is transferred to the base station node by way of relay. The close-range wireless transmission module of geological hazard sensor network adopts TI CC2530. The base station node is responsible for transmitting all the collected data to the server through GPRS module. If a disaster is to occur, the local people can be notified to evacuate or take measures to deal with the danger in time, so that the safety of the masses can be guaranteed. The feasibility and correctness of this scheme can be seen from the collected data. The scheme can run continuously and prove the stability of the system. From the point of view of energy, only when the data is collected, it is in normal working state, and the rest of the time is in low power consumption mode, which is very power saving.
