First, the working principle of reversing radar

Most of the reverse radar using the principle of ultrasonic distance measurement, the driver in the reversing (gear pushed to the R file, the system starts by the device in the rear of the probe to the rear of the vehicle to launch ultrasound, an obstacle after the echo signal, the controller The echo signal control processing, to determine the direction and distance of the obstacle.Finally by the display or buzzer issued images and sound prompts, so that the driver reversing the hearts of a few, more relaxed and safe.

Common name: car reversing radar crescent voice (6 probe)

Working principle: reversing the brakes when the probe in front of 30 seconds of working time, reversing radar detection maximum effective range is 2.5 meters (0.8 meters before the car), for different obstacles, the ultrasonic reflection of different intensity, the detection distance is also corresponding different.

Work: When the brakes in front of the probe power to start work, when the tread when the reverse gear, the rear of the probe power to work;

Before and after the probe does not work at the same time reasons:

Step on the brakes when the car forward, naturally away from the car after the obstacle farther, so the car is no longer necessary to detect.

The same flip gear, the car back, farther away from the front of the obstacles, there is no need to detect the alarm.

Second, the product function description

1, linked to the reverse when the system automatically enter the detection work installed state

2, 30CM-250CM cm level display accuracy, accurate display of obstacles distance

3, green, yellow, red three-color LED light bar shows the distance of obstacles

4, left and right obstacle position direction instructions

5, real voice sound alarm alarm level

6, dual CPU response quickly. Probe self-test function, the probe abnormal state prompts to avoid damage caused by the probe caused by the reverse collision;

7, embedded probe installation, easy to install, the probe color optional.

Third, the relevant parameters

1, real voice alarm tips;
2, green, yellow, red three colors 7 LED light bar tips obstacle distance;
3, 30CM ~ 250CM, centimeter display accuracy, accurate display of the distance of obstacles;
4, manual automatic alarm; 0.3-1.5m, less than 0.3m alarm: parking;
5, the probe self-test function, the probe abnormal state prompts to avoid damage caused by the probe caused by the reverse collision;
6, equipped with ultrasonic probe 6!
