汽车空调故障检测与诊断系统设计
摘要:随着经济的飞速发展,我国汽车的保有量不断增加,汽车的更新换代也非常快,自动空调技术被应用到汽车中,使其结构变得非常复杂。汽车在使用过程中由于人为和环境因素,故障的产生是不可抗拒的。汽车检测诊断技术在汽车技术保障中处于十分关键的地位,这就对汽车故障诊断提出了更高的要求。汽车故障的诊断方法很多,以前一直以修理工的经验判断为主,但随着汽车的发展,单纯凭经验对汽车进行维修已不能适应现代汽车技术要求。对于汽车专业人士,运用故障树分析法,利用数据统计知识从理论上对汽车故障进行分析,是一种非常简捷方便的诊断方法。它可以为维修提供理论分析依据,同时对汽车机件的设计改进提供参考。随着计算机的发展,故障树分析诊断在快速、准确方面得到进一步提高。关键词:故障树;自动空调;诊断
The design of vehicle air-conditioning on diagnosis and detection
Abstract:With the rapid development of economy, our country’s car ownership is increasing, the upgrading of car is also very fast, many new technologies are applied to automobile, and the structure es plicated. The generation of vehicles’ fault due to man-made and environmental factors is irresistible. Auto detection diagnosis technology in automotive technology is in a critical position, it puts forward higher requirements on automotive fault diagnosis. Motor fault diagnosis method are many, it had always give priority to with mechanic experience judgment, but with the development of the car, simply by experience of automobile maintenance already can not adapt to modern automotive technology requirements. For automotive professionals, using fault tree analysis, using statistical knowledge is a very simple and convenient diagnostic method. It can provide theoretical analysis basis for maintenance, and provide reference for improved design of automobile parts. Along with the development of puter, in rapid and accurate diagnosis of the fault tree analysis was further improved.
Keywords:fault tree analysis; air-condition; diagnosis
