中文摘要：

危险气源的搜寻对于排除安全隐患十分重要。基于气体传感器和单片机控制技术设计了一种危险气体泄漏源搜寻智能车系统,整个系统由气敏传感器探头、信号采集与控制端、驱动电路、机械载体和在IAR平台上基于C语言编写的控制算法5部分组成。危险气体泄漏源搜寻智能车实现了有毒有害气体的泄漏源搜寻、自主巡逻等功能,可以模拟嗅探犬进行危险气体泄漏源搜寻的工作。

英文摘要：

Searching for dangerous gas source is vital for the exclusion of security risks. The intelligent car system to find the gas leakage source was designed on the basis of gas sensor and MCU control technology. It consists of five parts（gas sensor,signal acquisition and control terminal,drive circuit,mechanical part,control algorithm compiled with C programming language on IAR Platform）. The intelligent car system achieve the functions of hazardous gas leakage source search,self-navigation patrol,etc. The intelligent car can imitate the sniffer dogs to complete the work of hazardous gas leakage source search.
