[0002] In the pump station operation process, accurate detection pool liquid level has extremely key significance. Liquid level data is directly related to whether the pump station can operate safely and efficiently, and the liquid level is too high to cause overflow risk, waste of water resources and adverse effects on the surrounding environment. At present, the commonly used pool liquid level monitoring methods in the pump station mainly include static pressure type liquid level meter monitoring, ultrasonic liquid level meter monitoring and floating ball type liquid level meter monitoring.

[0003] However, these existing liquid level monitoring methods have obvious drawbacks when facing strong wind weather. Strong wind will form significant waves on the surface of the pump station pool. For the static pressure type liquid level meter, the pressure fluctuation caused by the waves will cause a large error in the measurement result, making it difficult to accurately reflect the true liquid level. When the ultrasonic liquid level meter emits ultrasonic waves, the reflection path becomes complex and unstable when encountering waves, resulting in inaccurate time difference measurement, which affects the liquid level monitoring accuracy. The floating ball type liquid level meter will be shaken violently by the waves, causing the transmission device to provide a large fluctuation in the liquid level data, and unable to provide reliable liquid level information. These monitoring problems caused by strong wind waves pose a great challenge to the stable operation of the pump station.
