基于超声探测的自动报警装置的设计

我们所设计的超声波安全防控自动报警装置分为3个部分．第一部分是超声波探测系统．它负责对超声波探头前方的障碍物进行探测．根据障碍物的距离发出不同的警报声音;第二部分是单片机控制系统．负责对接收到的超声波信号进行处理，并输出自动报警控制信号;第三部分是自动拨号报警系统．负责接受单片机输出的自动报警控制信号．并自动拨号报警。本装置原理简单，效果显著．能够实现大范围的监控．并且能通过调整来适应不同的环境．抗干扰和隐蔽性都不错。

The designing of the auto-alarm device based on ultrasonic wave detecting

This ultrasonic wave auto-alarm device divides into 3 parts, the first part is the ultrasonic wave detecting system ,it is responsible to detect the obstacle in front of the ultrasonic wave detector, makes the different warning sound according to the obstacle distance; The second part is the SCM control system, is responsible for processing the received ultrasonic wave signal, and output auto-alarm control signal; The third part is the automatic dialing alarm system, responsi ble for accepting the auto-alarm control signal which the monolithic integrated circuit outputs, and the automatic dialing the police. This installments' principle is simple, the effection is remarkable, and it can realize the wide range monitoring, can adapt to the different circumstances, both of its antijamming and concealment is well.
