Ranging alarm system based on ultrasonic wave

Abstract

The invention provides a ranging alarm system based on ultrasonic waves. The ranging alarm system comprises a central processing unit, an ultrasonic ranging module, an alarm module, an ignition system and a display module, wherein the central processing unit comprises a communication device; the central processing unit is connected with the ultrasonic ranging module, the alarm module, the ignition system and the display module; a video information acquisition unit is mounted at the rear part of a vehicle body and is connected with the central processing unit; the central processing unit processes a received signal and compares the received signal with a set value, transmits an instruction to control the alarm module to alarm if the distance is smaller than the set value, emits voice information to remind a driver, and at the same time, transmits a control signal to the ignition system to control to shut down a vehicle. By adopting the ranging alarm system, the phenomenon that personal injuries can be caused when people back off vehicles can be avoided, and the ranging alarm system is high in performance cost ratio, simple to operate and good in use effect.
