基于GPRS在滑坡监测中的应用的研究
摘要
滑坡灾害监测普遍存在技术落后、自动化程度低的特点。滑坡体监测数据采集相对其他行业有其特殊性:一方面工作环境相对恶劣,条件较差,有时无法采用交流供电;另一方面传感器安装地点相当分散。而数据传输距离要求较远,一般情况单纯采用有线通信方式相当困难,甚至根本无法实现。近年来, 随着移动技术的发展, GPRS 逐渐被应用到滑坡监测中来。本文分析了GPRS 应用于状态监测中的优点, 通过与其它通信技术的比较, 提出了利用GPRS 进行状态监测的方案, ,综合各种因素我们选择GPRS方式来作为监测数据采集和传输的主要方式。通过对GPRS网络的远程数据采集系统的软硬件研究,表明GPRS网络方式构建网络化滑坡监测系统是可行的、经济的和方便的,为技术人员及时有效地远程监测滑坡体提供了便利条件。

GPRS Technology And Its Research Of Application In Slipper Monitoring
Abstract
Landslide disaster monitoring is generally at a low level in terms of technique and monitoring data collection of landslide has characteristics of (1)working in the relatively bad environment,difficult to use and supply alternating current sometimes, (2)quite difficult generally to adopt the munication because of the separate distribution of sensors and the long transmission recent years, along with the mobile technical development, the GPRS is applied to gradually the slipper monitors .This text analyzed GPRS that is applied in appearance advantage of monitoring ,passing to correspond with other technics' comparison, putting forward the exploitation GPRS proceed the project that appearance monitors. Considering various kinds of prehensively,we choose GPRS as the main technique of monitoring data collection and paper introduces the software and hardware on long— distance data collection based on result shows that this technique is and the technicians providing conveniently the long- distance monitoring the slippery on time and availably .
