摘　　要：根据天然气汽车推广过程中的实际需要,以半导体传感器、ATmega48和ATmega8为核心元器件,并采用485总线通信方式,设计了一种由控制器和探测器组成的天然气汽车气体检漏系统。在不同环境条件下测试系统报警所需的气体浓度,验证了系统设计的正确性和可靠性。According to the actual needs for the extending process of the natural gas automobile, using the semiconductor sensor,ATmega48 and ATmega8 as the core component and adopting 485 bus as the communication way, designed a kind of Gas leak hunting system composed by controller and probes for the gas automobile. At last, tested the required gas thickness to make the system alarm under different ambient condition, so verified the correctness and reliability of the system designed consequently
