Sludge detection method and instrument

Abstract

The invention discloses a sludge detection method and instrument. The sludge detection method is used for detecting sludge inside water and comprises the steps that the density and liquid level of a detection point are obtained at a frequency in real time; whether the density is larger than a first threshold value or not is judged, or whether the variable quantity of the density reaches a second threshold value or not is judged; the liquid level of the current detection point is marked as the first depth, and the detection point is updated; the density, strength and liquid level of the updated detection point are obtained; whether the density reaches a third threshold value or not is judged, and whether the strength reaches a fourth threshold value or not is judged; the liquid level of the current detection point is marked as the second depth, and the difference value between the second depth and the first depth serves as the thickness of the sludge. According to the sludge detection method and instrument, a density sensor, a liquid level sensor and a strength sensor are used for measuring the density, liquid level and strength of any detection point in real time, so that the thickness of the sludge is determined. The sludge detection method and instrument have the advantages of being accurate in measurement, high in real-time performance and convenient to use, reducing a large number of labor and material costs, greatly improving reconnaissance efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a mud detection method and a mud detector. Background technique [0002] With the improvement of the accuracy of river dredging, in the dredging work, it is required to be able to accurately locate the start position and end position of dredging, and it is required that the measurement data can be saved in real time, so that technicians can understand the condition of the river and guide the clearing Personnel dredging. [0003] At present, the traditional measurement methods at home and abroad are as follows: borehole sampling method, which uses a single-point drilling rig to collect columnar mud samples, but the borehole sampling cannot avoid the disturbance of the mud; The specific penetration resistance of the measuring rod is used to determine the thickness of the silt (the specific penetration resistance refers to the quotient of the total penetration resistance ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defect that the method of measuring sludge parameters in the prior art cannot obtain the thickness and density of sludge at the same time, and the operation is troublesome, and provides a sludge detection method and a sludge detector, which can measure in real time The density, liquid level and strength of any detection point can be used to determine the thickness of the sludge. The present invention has the advantages of accurate measurement, strong real-time performance, convenient use, reduced manpower and material costs, and greatly improved survey efficiency.
