Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a wave climbing measurement system based on a capacitive sensor. Background technique [0002] When waves act on the seawall structure, the difference between the elevation of the water body and the still water level after climbing along the slope of the embankment facing waves is the wave climb. In the design of seawall structures, the determination of the seawall top elevation that allows wave overtaking is mostly based on wave climb as a control index, that is, the top elevation of the embankment should intercept waves below a certain accumulation rate, and allow some large waves to pass over. embankment. For the design elevation of the seawall top, the climbing data is very important, which will directly affect the safety and cost of the project. The research on wave climbing has been of great scientific significance and engineering application value in the fie...

Problems solved by technology

The single-wave altimeter method is to place the wave altimeter directly on the seawall model. It is inconvenient to arrange the joint between the instrument and the wave surface of the model. The measured data signal needs to be exported separately after the test is over, the data is reprocessed, and then the statistics are carried out. After the analysis, the wave climb value of each accumulation rate can be obtained to determine how to adjust the next set of test plans. The main problems of this method are low test efficiency and inconvenient instrument layout.

The visual method is to place the steel ruler directly on the seawall model, and the test personnel observe and record the readings of the scale surface touched by waves one by one and then convert it into the climbing value. It is convenient, but its measurement accuracy depends entirely on the reading experience of the test personnel. At the same time, it is impossible to obtain the hourly process of the climbing height of the water body. It can only obtain the wave climbing value brought by some large waves and then conduct artificial statistics after the test. For the accumulation rate The statistics of the low climbing value and the average climbing value go back and the results are not accurate
