煤尘和湿度对红外瓦斯传感器的影响研究

 为了建立矿井内煤尘和湿度对红外传感器影响的模型，采用嵌入式处理器LPC2129和红外传瓦斯感器MH-440V设计了瓦斯浓度实时测量系统，系统主要由上位机和瓦斯浓度检测终端组成，检测终端通过对模拟环境中的瓦斯浓度进行采集后实时发送到上位机，上位机对数据信息进行接收、处理、分析、显示和存储。根据煤尘和湿度的特性，自建了模拟的煤尘和湿度实验系统，经过对红外瓦斯传感器进行了煤尘和湿度的影响实验，得出了煤尘对红外瓦斯传感器的影响呈线性的规律和湿度在一定时间内对红外瓦斯传感器的影响也呈线性规律的重要结论，成功建立了煤尘和湿度对红外传感器的实验模型。

Study on Coal Dust and Humidity Affected to Infrared Gas Sensor

In order to establish the model of dust and humidity affecting the infrared sensor in mine coal. The real-time gas concentration measurement system composed of the host computer and the methane concentration detection terminal was designed with embedded processor LPC2129 and infrared methane sensor. The detection terminal sent the data to the host computer after collecting the methane concentration from a simulated environment, and the host computer could receive, process, analysis, display and storage the data information. According to the characteristics of the coal dust and humidity, the simulated system of coal dust and humidity was established. After the infrared methane sensor experiments on the effect of coal dust and humidity, which came out that the coal dust linearly affected the infrared methane sensor, even the humidity was the same result within a certain time, establishing experimental models of dust and humidity on the infrared sensor successfully.
