我国大部分煤矿水文地质条件比较复杂，防治水工作重要而艰巨。目前市场同类仪器存在研发时间较早，普遍存在稳定性差、软件功能弱、测量精度低、采集功能单一、设备成本高等诸多问题，已无法适应目前煤矿防治水工作的需求。因此研制一款智能化、高性能、体积小、成本低的水文测量类设备对于弥补煤矿井下防治水监测手段显得尤为重要。 根据煤矿防治水工作需求及安全生产标准，设计测量仪的功能及技术指标。结合各项功能原理，完成了测量仪的总体方案设计，在此基础上对测量仪的硬件、软件和抗干扰性进行了分项设计。硬件系统方面结合仪器功能需求设计了多信号采集电路、主机显示电路、数据存储、电源保护电路、RS232通讯电路等。软件系统方面采用C#、C语言以模块化方式编写了功能强大的上位机及下位机数据处理程序，操作简单。同时为进一步提高测量仪整体抗干扰性能，从分析干扰源及其产生原因入手，硬件方面通过选择优质元器件、优化电路布置、合理接地技术；软件方面通过加入指令冗余、数字滤波等技术手段，保证了系统的稳定性和可靠性。 最后在实验室模拟环境及煤矿实地对测量仪系统整体性能进行了测试。试验结果表明测量仪系统测量精度达到设计性能参数指标，软件系统功能齐全，整个系统符合矿用安全生产标准；整体系统抗干扰性能优越。水文多参数测量仪的成功研制解为煤矿防治水工作提供更全面的监测手段。

he hydrogeological conditions of most coal mines in China are complicated, and the prevention and control of water is important and arduous. At present, there are many problems such as earlier R & D time, poor stability, weak software function, low measurement precision, single collection function, high equipment cost and so on, which can not meet the demand of coal mine water prevention and control work at present. Therefore, it is very important to develop an intelligent, high performance, small volume and low cost hydrologic survey equipment to make up for the underground coal mine water prevention and control monitoring means. According to the requirement of coal mine water prevention and control and safety production standard, the function and technical index of measuring instrument are designed. Combined with the principle of various functions, the overall scheme design of the measuring instrument is completed. On this basis, the hardware, software and anti-interference ability of the measuring instrument are designed separately. In the aspect of hardware system, multi-signal acquisition circuit, host display circuit, data storage, power protection circuit and RS232 communication circuit are designed. In the aspect of software system, the powerful data processing programs of upper computer and lower computer are programmed by using C#C language in modularization mode, and the operation is simple. At the same time, in order to further improve the overall anti-interference performance of the measuring instrument, starting with the analysis of the interference source and its causes, the hardware aspect through the selection of high-quality components, optimization of circuit layout, reasonable grounding technology, software through the addition of command redundancy, Digital filtering and other technical means ensure the stability and reliability of the system. Finally, the whole performance of the measuring instrument system is tested in laboratory simulation environment and coal mine field. The test results show that the measuring precision of the measuring instrument system reaches the design performance parameter index, the software system has complete function, the whole system conforms to the safety production standard of mine, and the whole system has excellent anti-interference performance. The successful development of hydrologic multi-parameter measuring instrument provides a more comprehensive monitoring method for coal mine water prevention and control.
