Method and device for automatically measuring thicknesses of different mediums

Abstract

The invention relates to a method and a device for automatically measuring thicknesses of different mediums. The method comprises steps: 1, a capacitance measuring device is started, capacitance value data of multiple capacitance measuring keys distributed in the vertical direction in an array mode are sequentially acquired by the capacitance measuring device, and a capacitance value data set formed by multiple capacitance value data is obtained; 2, the capacitance value data set is stored in a memory, inflection point searching and processing are carried out on the capacitance value data set to obtain at least one inflection point; and 3, according to positions of the capacitance measuring keys corresponding to all inflection points, thicknesses of different mediums are calculated and obtained, and the measurement is completed. Thus, the thickness of silt and the height of a water level can be monitored for a long time without manual intervention; the accuracy is high; the real-time performance is strong, the mounting is simple, the later maintenance workload is small, large-area extensive input is facilitated, the method and the device can be used for monitoring the thickness of the silt and the height of the water level in a water reservoir, a river way and a pipeline, and reservoir capacity calculation and water quantity measurement.

Description

technical field [0001] The invention relates to an automatic measurement method and a measurement device for different medium thicknesses. Background technique [0002] The measurement of silt thickness and water level has extensive and urgent needs in the fields of reservoir volume calculation, reservoir and river sediment monitoring, river flow measurement, river dredging, sewage pipe sediment measurement, and environmental governance. At present, there is no method that can monitor the speed and thickness of silt deposition in a large area and continuously for a long time. [0003] At present, the traditional measurement methods for sludge at home and abroad are as follows: borehole sampling method, which uses a single-point drilling rig to collect columnar sludge samples. The borehole sampling method has high manual intervention, low efficiency, and poor timeliness. At the same time, it cannot avoid the disturbance of sludge. ; Static penetrating method, through the sin...
