Description

Technical Field
The invention belongs to the technical field of magnetoelectric detection devices, and particularly relates to a magnetoelectric sensing type water level detection device and system.
Background
At present, in the static water level observation wells in the domestic earthquake precursor water level observation, most of the static water level observation wells need to be used for periodically calibrating the water level of the instrument. At present, a copper measuring clock is generally adopted in water level calibration, the measuring clock is hung on a long flexible rule in the using process, the measuring clock is hung in a water level well logging, the measuring clock is put down, when the measuring clock is put down to contact with the water surface, a sound is produced, the best contact position is found out through repeated tests, and the water level depth is read. In actual operation, the method sometimes has a low contact sound due to a deep water level, and is difficult to be accurately identified by a calibration person.
In terms of calibration principle, the water level calibrator is a simple water level measuring instrument at the end of the root, most of domestic research on water level measuring instruments focuses on water level measurement of hydrology and water conservancy, dams and the like, and is mainly divided into a water float type (more traditional), a pressure type, a photoelectric type, an electrode type and the like.
The mechanical water level measurement of the water float belongs to a more traditional measurement method, a water level measuring instrument using the float for measurement is applied in early water level observation, and the mechanical water level measurement of the water float is basically eliminated in the earthquake industry at present.

However, since the two pressure sensors are generally placed at different positions, the measurement accuracy is also affected by the difference of the ambient temperature.
The photoelectric water level measuring instrument uses a laser range finder as a core component, but in water level measurement, the laser reflectivity on the surface of a water body is not high for the water body with better light transmittance, and accurate measurement is difficult to realize only by using the laser range finder. In this measuring method, a reflective float needs to be arranged in the water.
The electrode type water level sensor uses two electrodes as sensors, and is placed in water, and the water is used as a conductor to connect the two electrodes to form a loop to generate an electric signal and send an indication signal. The measurement mode is influenced by the conductivity of the measured liquid, and the measurement cannot be carried out on the liquid with weak conductivity or even non-conductive liquid.
Therefore, a water level detecting device with high sensitivity, easily identified signal, good measuring accuracy and small error is needed.
