Description
Technical Field
[0001] The present invention relates to the technical field of water level detection, and in particular to a high-stability water level detection device, a detection method, an electronic device and a computer-readable storage medium. Background Art
[0002] Existing water level detection usually uses a liquid level meter, sets up multiple pressure sensors in the deep foundation pit to calculate the water level using pressure values, or uses ultrasound for non-contact detection. The first type of liquid level meter is affected by various environmental factors on site and its own accuracy, resulting in low detection accuracy. The second method of using pressure values requires the early installation of multiple pressure sensors on the inner wall of the deep foundation pit, which is difficult to construct and has high labor costs. In addition, the arrangement, location, and number of pressure sensors will affect the water level detection accuracy. The third ultrasonic detection method uses the time difference between the transmitted and received ultrasonic waves to calculate the water level. Although non-contact detection is achieved, the ultrasonic probe is not in an absolutely vertical state in actual detection, resulting in the ultrasonic signal being unable to be absolutely perpendicular to the water surface. The detection accuracy is low due to the inclination angle between the ultrasonic signal and the water surface. To address this problem, the prior art usually sets the ultrasonic probe to The ultrasonic probe is placed on a horizontal plate-type leveling structure, and lifting rods are arranged around the leveling structure. The angle of the ultrasonic probe is adjusted by moving the lifting rods up and down. This method requires a complex mechanical structure to drive the lifting and lowering of the lifting rods. The lifting distance is difficult to accurately control. The detection accuracy depends on the adjustment precision of the lifting rods, and the accuracy is low. The probe must be fixedly connected and vertical to the leveling device. When in use, the leveling device and the probe must be fixed above the water level to be measured. The portability is poor and the flexibility is low. The adjustable angle is small due to the short lifting distance of the lifting rod, which is not suitable for leveling with a large inclination. In addition, the water level detection device usually uses a fixing rod combined with a screw or other fixing method to install the adjustment structure. Its stability depends on the connection tightness between the fixing part and the screw and other mechanisms. As the use time increases, the connection firmness between the fixing part and the screw will become loose, thereby causing the stability of the entire detection device to decrease. Therefore, it is necessary to design a high-stability water level detection device, a detection method, an electronic device and a computer-readable storage medium to solve the above technical problems.
