井下环境参数异常的变频采集环节设计

Abnormal Environmental Parameters Underground Part of Design Frequency Acquisition

该监控系统由多参数环境监测装置(如CO、瓦斯、温度、风速等)、就地显示装置、数据存储装置等组成。为了能够准确捕捉井下环境参数异常或事故发生时的详细数据,提出了变频数据采集策略,以解决长时间记录与存储介质容量有限的矛盾。通过实验研究本系统取得了良好效果,能够满足煤矿井下环境的使用。

The monitoring system has multi-parameter environmental monitoring devices （such as CO, gas, temperature, wind speed, etc.）,local displays, data storage devices and other components. In order to accurately capture underground environment parameters abnormal or accident detailed data, presents frequency data collection strategies to address long record and limited capacity of storage media contradiction. Through experiments to study system and achieved good results, can be used to meet coal mine environment.
