【摘要】 水害作为煤矿井下主要灾害之一，严重威胁着煤矿的安全生产。为防止水害，在矿井井田范围内，建立了许多水文地质钻孔，以便观测各含水层水位、水温、水质随气候、季节、采动的变化，指导防治水工作。此外，开发地下水电导率、PH值、混浊度的测量技术对地震短期预报具有十分重要的意义。针对目前钻孔水文监测系统的现状和存在的主要问题，我们设计了一种集信息采集技术、信息无线传输技术、信息处理技术及预测预报技术于一体的基于GPRS的钻孔水文无线遥测系统。本系统采用网络化体系结构，为系统的以后扩展提供了很大的方便，除了水位的测量外，还可用于水温、水质等相关数据的测量，应用范围广阔。系统包括现场部分、公共GPRS网络部分和监测中心部分，具有三层网络结构。现场部分主要由智能传感器、遥测仪、GPRS模块组成，各种智能传感器与遥测仪组成RS-485总线通信网络。智能传感器完成水文信息的测量，遥测仪定时循环唤醒各智能传感器测量水文数据，各智能传感器将测量的水文数据通过RS-485总线传送给遥测仪，由遥测仪进行集中处理、存储，并通过GPRS模块、GPRS网络将监测信息以无线传输方式发送到监测中心的监测计算机，完成数据的永久保存、打印输出，通过局域网可实现共享。监测计算机的控制命令或查询命令也可以通过GPRS网传送到遥测仪中，对各个智能传感器实行远程控制。本文着重阐述了系统方案的选择，遥测仪、智能传感器及监测计算机软件的设计思路、工作原理、实现方法，并详细介绍了相关硬件电路和软件工作流程的设计。本系统优化了传统的钻孔水文监测系统，并与无线通信技术相结合，实现了钻孔水文监测的自动化、智能化、模块化、层次化和网络化。具有成本低廉、分布灵活、传输可靠等优点，有较高的社会推广价值。更多还原

【Abstract】 Water disaster as one of the main disasters in coal mine influences the safety production of coal mine severely as one of the main disasters in coal mine. To prevent water disaster, some hydrology geologic drills are established in the domain of mine to observe the variation of the water level, water temperature, water quality of each aquifer with the change of climate, season, mining. Moreover, the exploitation of measure technology in ground water conductance, PH value, turbidity has important significance to earthquake short term forecast.Considering the drill hydrology monitoring system status quo and the existing main problems, we design wireless remote measurement system of drill hydrology based on GPRS which integrates information gathering technology, information wireless transmitting technology, information processing technology and forecast technology. Network system frame is adopted in the system, prodigious convenience is provided for the future spread of the system, except that the water level measure is applied, some correlation measures such as water tempreture, water quality are applied, the application area is capacious. The system contains three networks which is locale, commonality GPRS network and monitoring center part. The locale part is composed of intelligent sensor, remote indicating instrument and GPRS module. Various intelligent sensors and remote indicating instrument make up RS-485 communication network. Hydrology information measure is achieved by intelligent sensor, remote indicating instrument arouses every intelligent sensor to measure hydrology data by timing in circle, every intelligent sensor transmits the measure hydrology data to remote indicating instrument by RS-485, the data are disposed and stored collectively in remote indicating instrument, then the monitoring information are transmitted immediately by GPRS module, GPRS network in wireless to monitoring computer of the monitoring center which the data are stored enduringly, printed and shared by LAN. The control instructions or enquiry of monitoring computer can transmit to remote indicating instrument by GPRS network to carry out long-distance control to every intelligent sensor.In this paper the choice of the system project, the method, work principle, realizing method of remote indicating instrument, intelligent sensor, and of the monitoring computer software are mainly introduced, the related hardware circuit and software working flow are introduced in detail.In the system the traditional drill hydrology monitoring system is optimized combined with wireless communications. Automatic, intelligence, modularization, layering and network of the drill hydrology monitoring have been achieved. The system has such merits as low cost, flexible distributing, credible transmitting and so on, it has great value of social generalization.更多还原
