Embodiment 1
[0051] Such as figure 1 As shown, the present embodiment provides a kind of silt detection method, and this silt detection method is used for detecting the silt in a water body, and it comprises the following steps:
[0052] Step 101, detecting the density and liquid level of the detection point in real time with a frequency;
[0053] Step 102, converting the density signal of the density into a first electrical signal, and converting the liquid level signal of the liquid level into a second electrical signal;
[0054] Step 103, amplifying the first electrical signal and the second electrical signal;
[0055] Step 104, judging whether the density is greater than a first threshold or whether the variation of the density reaches a second threshold, if so, proceed to step 105, if not, update the detection point and return to step 101;
[0056] Step 105, record the liquid level of the current detection point as the first depth and update the detection point;
[0057] Step 106, ...
Embodiment 2
[0083] In this embodiment, the functional modules capable of calculating the mud thickness in Embodiment 1 are integrated into specific hardware, such as the first judging module 7, the marking module 8, and the second judging module in Embodiment 1. 9 is integrated in the computer of this embodiment, and will be described in detail.
[0084] Such as image 3 As shown, the present embodiment provides a sludge detector, which includes a density sensor 1, a liquid level sensor 2, an intensity sensor 3, a first amplifier circuit 4, a second amplifier circuit 5, a The third amplifying circuit 6, a single-chip microcomputer 7', an RS485 interface chip 8' (RS485 is a serial physical interface standard formulated by the American Electronics Industry Association) and a computer 9'.

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 ...
