该电路采用延时的方法,将超声回波信号依次延时,产生立体声报警信号,用于检测障碍物。该电路包括发射单元(10)、接收单元(20)、将回波信号转换成用于检测障碍物方向的可听信号的信号处理单元(30)和系统控制单元(40)。
The circuit utilizes the delaying method which delays the ultrasonic echo signals successively and generats the stereo audible warning signals for the detecting the obstacles. The circuit includes a transmitting unit (10), a receiving unit (20), a signal processing unit (30) converting the echo signals to the audible signals for detecting the direction of the obstacle, and a system control unit (40).
