摘　　要：为了解决煤矿坑道口和沼气池等近程的甲烷浓度探测不安全的问题,设计一种用于甲烷浓度探测的红外遥控小车,操纵小车,采用灵敏度可调的气敏元件MQ-2探测目标甲烷浓度,通过单片机和无线收发模块,在手持式终端上显示甲烷浓度。该探测小车具有非接触、响应快、测量精确等优点,方便用于日常生活、工业检测等。In order to solve the issue of the unsafe detection of methane concentration in the mine pit crossing and biogas pool, this paper designs a kind of infrared remote controlled vehicle. By controlling the car, using a sensitivity adjustable gas sensitive element MQ-2 methane concentration is detected. By using the wireless module and single chip processing, the hand-held terminal displays the methane concentration. The detection of the mini-car has advantages of non-contact, fast response and high accuracy. It＇ s convenient for daily life and industrial detection.
