【摘要】 随着煤矿开采由浅部进入深部，矿井受水害威胁的程度越来越严重。而目前，矿井一般由人工定期对所选定的观测点逐点测量，难以获得各测点的同时涌水量，不利于分析涌水点的涌水情况，特别是有突水发生时，不能及时发现。针对目前矿井水文安全监测系统的现状及存在的主要问题，我们设计了一种集信息采集技术、信息传输技术、信息处理技术及预测预报技术于一体的矿井水文自动监测报警系统。该系统由水压、水位、流量智能传感器完成现场数据的采集，再由通信分站将监测数据送入监控计算机，可以全面、实时、自动地对监测数据进行集中记录、处理、存储和报警，在此基础上，监控计算机将有关信息送入矿内局域网，有关人员通过计算机网络，就可对系统监测数据和工作状况进行浏览、查询和控制。满足了生产单位对矿井水文状态实行全面、实时、长期监测的要求。 本文系统阐述了系统方案的选择，通信接口、通信分站、水压智能传感器、水位智能传感器、流量智能传感器的设计思路、工作原理、实现方法，并详细介绍了M-Bus总线技术，M-Bus总线主机接口电路设计原理。 本系统优化了传统的矿井水文自动监测报警系统，将多种监测技术相结合，实现了矿井水文监测的自动化、智能化、模块化、层次化和网络化，具有较高的社会推广价值。更多还原

【Abstract】 With the exploitation of the mine deeper, the degree of the water harm which the mine is subjected to, is more and more serious. But generally, the measures in the many mines are artificial periodically. So it is difficult for us to get the value in the same time. Especially we can not find the danger if the water effuses suddenly. Considering the hydrology safety monitoring status and the existing main problem, we designed this automatic hydrology safety monitoring and alarming system which integrates modern signal gathering technology, signal transmitting technology, computer information processing technology and computer network technology. The system, which collects the field data through hydraulic sensors, water level sensors and flux sensors, and then transmits the monitoring data to the surveillance computer by the communication distributed stations. The system can register, process and memory the monitoring data together and alarm completely, real time and automatically. On basis of this, the surveillance computer will send the related information to the local area network so that the related workers can browse, inquire about and control the system by the network. The system satisfies the production units’ demand that it can monitor the hydrologic state completely, real time and chronically.This paper mainly introduces the choice of the system project, communication interface, communication distributed station, and the working principle, realizing method, the related hardware circuit and the design of the software working flow of the hydraulic intelligent sensors, water level intelligent sensors, flux intelligent sensors. And in this paper we introduce the M-Bus technique and the design principal of the interface circuit of the M-Bus host.The system optimizes the traditional hydraulic automatic monitoring and alarming system. It combines many kinds of monitoring techniques and realizes automatization, intelligence, modularization, hiberarchy and network and has更多还原
