When we are about to hit things, our cars will make a report to the police to remind us to effectively prevent reversing accidents. Do we know the working principle of the reversing alarm?

The working principle of our reversing alarm is to use the circuit of the reversing light. When the driver hangs the reverse gear, the alarm relay is connected to make a small electric speaker intermittent sound.

Direct alarm, it can automatically detect the distance of the tail obstacles. When it reaches the limit position, it can send a sound and light alarm to remind the driver to brake. The ultrasonic distance sensor uses voltage component vanadium titanium lead, which is generally called RZT. This sensor is characterized by directionality. The reversing sound system used by the car uses the "echo" phenomenon of the ultrasonic distance sensor. The ultrasonic wave is emitted behind the vehicle, and the time when the ultrasonic wave is returned after encountering obstacles, the distance from the car to the obstacle can be obtained.

The reversing alarm has played a very important role in our driving safety, so we must pay attention to it, and those in need can contact us!
