What is the advantages and principle of ultrasonic parking space guidance syetem

ultrasonic parking space guidance syetem is base on ultrasonic detection which is a non -destructive detection method that uses material and acoustic performance differences to the ultrasonic transmission waveform reflection situation and the energy changes of penetration time to test the internal defects of the material.

The pulse reflector uses longitudinal waves during vertical detection, and horizontal waves are used during oblique shooting. Pulse reflexes have longitudinal wave detection and horizontal wave exploring. On the screen of the ultrasonic instrument, the horizontal coordinate represents the transmission time of the sound waves, and the echo signal amplitude is represented by vertical coordinates.

For the same uniform medium, the transmission time of pulse waves is proportional to the sound of sound. Therefore, the existence of defects can be judged by the emergence of the defective echo signal; the position of the emergence of the echo signal can determine the distance of the defect detection surface and achieve defect positioning; judge the equivalent size of the defect by the return amplitude.

Advantages of ultrasonic detection:

1. Suitable for non -destructive testing of various parts such as metal, non -metal and composite materials

2. Defect positioning is more accurate

3. The detection rate of area defects is higher

4, high sensitivity, defects with small internal size of the test parts

5. Nose not to human and environment

6. Do not destroy the sample
