Groundwater level measurement method and device based on potential method and computer equipment

Abstract

The application relates to a groundwater level measurement method and device based on a potential method, computer equipment and a storage medium. The method includes: obtaining a groundwater level measurement request based on the potential method; initializing measurement equipment according to the groundwater level measurement request; starting a line pay-off motor, and calculating length, whichis passed through by a detector, at the same time through an encoder; recording a resistance value of a loop formed between the detector and the ground through the measurement equipment when the detector detects a water surface; and when the resistance value is less than a preset threshold, stopping line pay-off, and calculating and obtaining current water surface height according to the currently recorded resistance value and the line pay-off length. The method realizes high-precision measurement through a single-line-type detection method. In addition, the measurement method of the invention can realize full-automation and high-precision water level measurement, effectively reduces a labor intervention degree, labor intensity and construction monitoring expenditure of on-site construction monitoring personnel, and realizes saving of manpower and material resource costs.

Description

technical field [0001] The invention relates to the technical field of measurement methods, in particular to a method, device, computer equipment and storage medium for measuring groundwater levels based on the potential method. Background technique [0002] At present, the measurement of groundwater level in engineering is an important indicator to ensure the safety and quality of the surrounding construction environment. Engineering personnel need to measure water level changes regularly, especially in underground engineering construction or sensitive areas affected by groundwater. Changes in groundwater level have great impact on projects. Safety plays a key early warning role, because to ensure the safety of construction, changes in groundwater levels must be closely monitored. Under normal circumstances, when the groundwater level does not change much, ready-made engineering personnel use the once-a-day measurement method to calculate the change of the water level, but ...

Problems solved by technology

[0003] In the traditional technology, the existing method of measuring the change of the groundwater level mainly relies on the steel ruler water level gauge to measure the change of the groundwater level. This kind of instrument must be operated by manual observation, and it is basically impossible to realize fully automatic measurement and data transmission. And the error is relatively large

Although piezometers in some instruments can automatically measure water level through wireless data transmission, piezometers are easily affected by changes in temperature, air pressure, and water quality due to their own measurement principles, resulting in very poor water level measurement accuracy. The measurement accuracy is far greater than 10mm, the reference value of the measurement is not very great, and it is not suitable for large-scale promotion and application
