Description

Technical Field

[0002] Ultrasonic signal detector is a common electronic device used to measure the distance between an object and a sensor or detect the existence of an object. It uses the characteristics of ultrasound for measurement and detection. Ultrasonic waves are mechanical waves with a frequency higher than the human hearing range. Ultrasonic signal detectors achieve measurement by emitting ultrasonic pulses and receiving the echo reflected back to the sensor. The ultrasonic transmitter in the sensor emits ultrasonic pulses, and then the listener receives the reflected waves and calculates the distance between the object and the sensor by measuring the time difference of the pulses.

[0003] Most existing ultrasonic signal detectors are directly installed on the equipment. When the equipment is moving, the ultrasonic signal detector may collide with obstacles and cannot be protected. The ultrasonic signal detector is easily damaged. Therefore, we propose an ultrasonic signal detection device with protective function. Utility Model Content
