摘要
针对现有煤矿中使用的瓦斯传感器存在的问题,提出了一种以C8051F040单片机为核心的红外瓦斯传感器设计方案。利用气体对红外辐射有选择性吸收的原理来检测瓦斯浓度。并在数据通信方面采用CAN总线方式,提高了数据通信速率和可靠性。
A novel design of the infrared gas sensor have been proposed based on C8051F040 owing to the deficiency of the existing gas sensor.Using the infrared radiation selective gas absorption principle to detect gas concentration.For improving the data communication rate and reliability,CAN bus method has been applied in the data communication system.
