煤矿井下监控分站数据采集系统设计(软件)

摘要
在人类发展的过程中,认识世界与改造世界是两部分最主要的过程。而监测监控系统对于它所要控制的对象亦是如此,即“测”与“控”的过程。监测监控系统是现代化生产与管理的有效工具,在整个的国民经济中都有着广泛的应用,例如:交通、能源、冶金、化工等。
对于监控系统而言,监控分站就是其下位机,有着至关重要的作用。对煤矿井下监控分站的研究中,主要包括了对四路模拟通道的循环采集并显示它们所代表的物理量的数值。四路模拟通道兼容电压信号和频率信号,分别代表了***浓度、CO浓度、温度以及湿度信号。就功能而言,对于监控分站的设计已经成功完成。但是它还具有许多可以扩展的地方,如:遥控远程控制、多功能报警等。
监控分站在整个监控系统起着数据采集的基本功能,对于可以实现基本功能以及一些扩展功能的分站在实际的生产中都具有十分广泛的应用。

ABSTRACT
In the course of human development, understanding of the world and transform the world are the most important two-part process. The monitoring and control system to control the object is also the same that "measured" and "control" process. Monitoring and control system is a modern production and management of the rational tools throughout the national economy has a wide range of applications, such as: transportation, energy, metallurgy, chemical industry and so on.
For monitoring systems, monitoring and control station is its lower position, has a vital role. Coal mine monitoring and control station for the study, included a cycle of four analog channels captures and displays the physical quantity they represent value. Four channel analog patible with voltage and frequency respect the gas concentration, CO concentration, temperatures and humidity signals. In terms of features,the design of monitoring and control station has pleted essfully. But it can be extended with a number of places, such as: remote control remote control, multi-function alarm.
Standing the whole monitoring system,monitoring and control station plays a basic functions of data collection. For some monitoring and control stations which achieving basic function and expand function have a widely used in the actual production.

Keywords: multi-channel data acquis
