Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic position detection, in particular to a novel ultrasonic position sensor. Background Art

[0002] Traditional ultrasonic position sensors are widely used in the fields of liquid level measurement and water depth detection. Specifically, ultrasonic sensors transmit ultrasonic waves, which are reflected back after encountering the object or liquid surface being measured. The sensor receives the reflected wave and calculates the distance by measuring the time difference between transmission and reception.

[0003] However, traditional ultrasonic position sensors face many problems in practical applications, especially in flowing waters or water environments with large fluctuations. Since the sensor is prone to tilt under the impact of the water flow, it is difficult for the sensor to maintain stability, resulting in inaccurate measurements, inaccurate measurement results and damage to the sensor due to collision with underwater obstacles driven by the water flow. In addition, the data transmission line of the sensor is easily affected by moisture and damage in an underwater environment, resulting in sensor failure and data transmission failure, affecting the reliability and accuracy of data transmission.

[0004] For example, application number CN201922186680.1 discloses a wireless depth measuring instrument, which includes an acoustic transducer, an ultrasonic sensor, an analog-to-digital converter, a digital signal processor, a camera, a pressure sensor, a pulse width modulation chip, a motor, a propeller, a 4G module and a smart phone structure. The underwater signal is transmitted to a remote end in the form of a GPRS signal, and the distance between the wireless depth measuring instrument and the bottom of the water is measured by the acoustic transducer. It is used for mobile measurement of water depth and ensures the quality of signal transmission. However, it has the defects of complex structure, high cost and inaccurate signal caused by noise interference in wireless communication.

[0005] Therefore, when measuring water depth in flowing waters, an improved ultrasonic position sensor is needed to solve the above problems. Utility Model Content
