The invention discloses a reversing safety detection device for a special vehicle, which effectively solves the problem that the driving safety of the special vehicle is influenced due to short operating distance and unstable effect of a reversing radar of the special vehicle; the device comprises a signal receiving circuit and a signal processing circuit; the signal receiving circuit enables an ultrasonic signal, detected by an ultrasonic sensor U1, in a blind area of a special vehicle to pass through a filter and a subtractor to obtain a difference signal, and transmits the difference signal and the ultrasonic signal to the signal processing circuit. And the signal processing circuit receives the ultrasonic signal and the difference signal by using an adder to obtain a standard signal, and the standard signal starts the controller, so that the safety of the special vehicle during reversing is guaranteed.
本发明公开了一种用于特种车辆的倒车安全检测装置,有效的解决了特种车辆的倒车雷达因其作用距离短、效果不稳定进而影响到特种车辆的行驶安全的问题出现,本发明包括信号接收电路、信号处理电路,所述信号接收电路将超声波传感器U1检测到特种车辆盲区内的超声波信号经过滤波器、减法器后得到差值信号,信号接收电路并将差值信号与超声波信号传输至信号处理电路,信号处理电路利用加法器接收超声波信号与差值信号得到标准信号,标准信号将控制器启动,保障了特种车辆在倒车时的安全。
