| 摘 要： | 为了数字化监控矿井瓦斯浓度,研制了一种基于高性能ATmega8单片机的矿井瓦斯浓度测定系统,介绍了瓦斯浓度测定系统的信号采集原理和设计程序.系统通过实时采集瓦斯浓度传感器的变换电压,将其数字化为实际瓦斯浓度值,并经远程数据传送模块将数据传送到井上计算机监测平台进行处理.试验结果表明,该系统可以安全准确地采集瓦斯浓度数据和及时处理瓦斯浓度信号,具有瓦斯浓度状况监测、历史记录数据查询和数据分析等多种功能.

| Abstract: | A new style of measuring system for mash gas concentration is introduced, which is based on the ATmega8. The output voltage of the gas sensor is measured in real time, it is converted to real gas concentration data and then transformed to the measuring computer flat. The system has the monitoring function on concentration of the gas and the query and analysis functions on recorded data. It can be used safely and reliably. The signal of gas concentration can be treated in time. A new way of gas concentration digital process monitoring is provided. 4 figs, 6 refs. |
