摘　　要：为了研究基于超声波测距的安保系统在实际应用中会出现的误差,设计出一种利用超声波测距作为安保系统的电路并在此基础上对安保系统的可靠性进行研究。该系统采用单片机STC89C52RC为控制芯片,利用超声波测距模块进行测距,在单片机内部进行距离比较并判断是否报警。同时对影响报警系统的一些因素进行分析并提出一些改进方法。通过研究分析,提出一些影响安保系统可靠性的因素,为基于超声波测距的安保系统在生产生活中的运用提供一些参考。In order to study the error in the application of the security system based on ultrasonic distance measurement,design a security system circuit composed of ultrasonic distance measurement and on the basis of this, the reliability of the security system is studied. The system uses a single chip microcomputer STC89 C52 RC as the control chip,ultrasonic distance measuring module is used for ranging. Comparison distance and judge whether the alarm in the single chip microcomputer. At the same time,analyze some factors affecting the alarm system and put forward some improved methods. After a through analysis,put forward some factors that affect the reliability of the security system,to provide some reference for the application of the security system based on ultrasonic distance measurement in the production and life.
