2、量的的监控系统并不利于生产技术、文化水平相对较低的中小型煤矿。因此,必须贯彻“安全第一,预防为主”的方针,加强对中小型煤矿井下环境的监控,以确保煤矿的安全生产。本文基于中小型煤矿的实际需求,主要研究设计十六路输入、八路输出的监控分站的硬件及上位监控系统。该系统由信号采集、数据通信和计算机监控三大子系统组成,在文中运用模块化设计思想完成各子系统的硬件电路和软件程序的设计。监控系统的硬件部分主要介绍了硬件系统的组成以及各主要模块的电路实现。该系统基于微控制芯片msp430f135,采用max1480b数据通信接口电路,以实现高速远距离传输数据;采用串行接口的键盘显示专用芯片ch451来实现实时数据

3、、历史数据以及各种状态图、状态表的显示。硬件部分详细介绍了数据.更多通信接口电路,数据显示电路,电源转换电路以及采集信号的输入输出电路,并分别给出了各个电路的实现电路图。整个硬件系统线路连接简便,能够适应煤矿的恶劣环境,具有良好的通用性,并且具有扩展性强、便于调试、安装和维护等优点。监控系统的软件部分,是课题研究的重点,从该系统的结构组成入手,介绍了系统的主要模块以及相应模块的编程思想,主要内容包括:1、实现了上位系统软件与下位分站的数据编码、数据通信,对监控数据的计算、超限判定、声光报警、非本质安全电路的断电控制;2、实现了对模拟量、数字量等监控数据的实时显示和记录,用户可在“模拟量实时数据

4、监测表”、“数字量实时数据监测表”中查看固定位置传感器的实时报警记录和断电记录,可以在“数据查询”和“历史曲线”界面完成对历史数据和历史曲线的按日期或者按班次查询,详实的历史数据可以为用户提供第一手的安全资料;3、用户还可在“工作现场”的模拟图界面实时观测动态变化的工作现场,更加直观的了解报警位置和断电位置;4、根据监控系统的总体控制要求,系统实现了远程控制、异步控制和就地控制,通过不同方式的断复电控制,最大限度的避免事故的发生。本监控系统基于visual basic开发平台,采用模块化的设计思想,具有研发周期短,可扩展性强,便于移植安装,数据库维护简单等特点,方便今后系统的进一步修改和添加功

5、能。本文为煤矿安全生产监控提供了一种新的设计思路和新的设计方案,是多种技术相结合的产物,是各种技术广泛应用和进一步发展成熟的体现,相信这一系统会在煤矿领域得到进一步推广。【英文摘要】 china is a great nation with rich coal resource.so many coal minds are seattered in the country and provide powerful energy support for the national economy development. but for a long time,the countrys coal
