Description

TECHNICAL FIELD

[0001] The present application relates to a self-adaptive grouping wave height instrument array control system, in particular to a self-adaptive grouping wave height instrument array control system and control method. BACKGROUND

[0002] In the field of ship and ocean engineering test, in order to understand the seakeeping of ship, ocean structure, breakwater and the like, many tests need to measure and analyze the wave height of water surface wave, and wave test is an important part of engineering design of ocean, estuary coast, harbor, ship and water conservancy.

[0003] At present, when model wave test is carried out in the laboratory, a wave height instrument array is needed to measure the wave parameters of a certain area in the test tank in many cases. When measuring, we generally hope to group the wave height instruments on the same wave crest line for observation, and group the wave height instruments on different wave crest lines for observation. The grouping observation is usually carried out after the test, and the collected wave height data is combined and analyzed by manual, and then the test scheme is adjusted according to the analysis result. This way is time-consuming and laborious, and the wave height and period of the wave height instrument array measurement area in the test tank cannot be observed in real time during the test.

[0004] How to design a self-adaptive grouping wave height instrument array control system and control method for the laboratory test tank with strong professional characteristics, which can realize self-adaptive grouping of the wave height instrument array according to different wave crest lines, and can observe the wave height and period of different wave crest lines in real time during the test, to meet the wave height instrument array measurement wave demand in the laboratory test tank is a problem worth studying. SUMMARY

[0005] The present application aims at the above-mentioned problems, and provides a self-adaptive grouping wave height instrument array control system and control method.

[0006] The present application can realize self-adaptive grouping of the wave height instrument array according to different wave crest lines, and can observe the wave height and period of different wave crest lines in real time during the test.

[0007] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme:

[0008] A self-adaptive grouping wave height instrument array control system, comprising a wave height instrument array, a wave height collection module, a self-adaptive grouping control module and a display output module.

[0009] The wave height instrument array and the wave height collection module are connected through an RS485 interface, for measuring the wave height signal of the test wave and transmitting the wave height signal to the wave height collection module;

[0010] The wave height acquisition module is connected to the adaptive group control module and is used to output the acquired wave height data from each channel to the adaptive group control module.

[0011] The aforementioned adaptive grouping control module is connected to the display output module and is used to adaptively group the wave height meter array according to different wave crest lines, while simultaneously outputting the observation results to the display output module in real time.

[0012] The aforementioned display output module is connected to the adaptive grouping control module and is used to display the observation results in real time.

[0013] The present invention further provides a control method for an adaptively grouped wave height meter array control system, the method comprising:

[0014] Arrange the wave height meter array in the test pool according to the test plan. The wave height meter array can be a rectangular array or any other arbitrary shape array.

[0015] During the experiment, once wave generation begins, the experimenters control the adaptive group control module to start collecting wave height data from the wave height meter array. The adaptive group control module sends a control signal to the wave height acquisition module to start wave height acquisition.

[0016] The wave height acquisition module begins acquiring wave height data signals from the wave height meter array and outputs the wave height data to the adaptive group control module in real time.

[0017] The adaptive group control module monitors wave height data signals in real time. For an M-row, N-column wave height meter array (where M and N are natural numbers), if it detects that, starting from a certain moment, at least one wave height data point in the array has an absolute difference from its initial zero position greater than the maximum fluctuation threshold in still water, that is, at time t1, there are X (1≤X≤M*N) wave height data points H1, H2, ..., H... X All satisfy |H X –H0|>TH (H0 is the initial zero-position wave height data, TH is the maximum fluctuation threshold in still water), then this X-channel wave height data signal is classified into the first group; subsequent monitoring continues, if at time t2 there are Y (1≤Y≤M*N) channels of wave height data H1, H2, ..., H Y All satisfy |H Y If –H0|>TH, then this Y-channel wave height data signal is grouped into the second group, and so on, until all channels of the wave height meter array have been grouped.

[0018] After the adaptive grouping control module groups all wave height data signals from the wave height meter array, it monitors and analyzes the wave height data signals in real time by group, and calculates the average wave height of each group. That is, for a wave height meter array divided into Z (1≤Z≤M*N) groups, the average wave height H of each group is calculated. A1 HA2 , …, H AZ , where H Ai = H i1 + H i2 + … + H ij / j (i can take 1, 2, …, Z), j is the number of wave height instruments contained in the Zth group of wave height instrument arrays, H ii is the wave height calculated by the jth wave height instrument in the ith group of wave height instrument arrays.

[0019] After the adaptive grouping control module groups all the wave height data signals of the wave height instrument arrays, it monitors and analyzes the wave height data signals in real time by group, and calculates the average wave period of each group, that is, for the wave height instrument arrays divided into Z (1≤Z≤M*N) groups, the average wave period T A1 , T A2 , …, T AZ is calculated for each group, where T Ai = T i1 + T i2 + … + T ij / j (i can take 1, 2, …, Z), j is the number of wave height instruments contained in the Zth group of wave height instrument arrays, T ii is the wave period calculated by the jth wave height instrument in the ith group of wave height instrument arrays.

[0020] The adaptive grouping control module outputs the data of each group of wave height instrument arrays to the display output module, and outputs the wave height values, average wave height values, and average wave period values of each group of wave height instrument arrays in real time on the display output module.

[0021] When the wave making is completed, the test personnel control the adaptive grouping control module to stop collecting the wave height data of the wave height instrument arrays, the adaptive grouping control module stores the collected wave height data by group, sends a control signal to stop wave height collection to the wave height collection module, and stops outputting data to the display output module.

[0022] The wave height collection module stops collecting the wave height data signals of the wave height instrument arrays, and the display output module stops displaying the data of the wave height instrument arrays.

[0023] The characteristics and beneficial effects of the present application relative to the prior art are mainly:

[0024] 1. It can realize adaptive grouping of wave height instrument arrays according to different wave crest lines, and is effective for wave height instrument array arrangements of any shape.

[0025] 2. It can observe the wave height and period of different wave crest lines in real time during the test, which provides a guarantee for better test work.

[0026] 3. The automatic combination and analysis of the collected wave height data improves the test efficiency and saves the human resources in the test. BRIEF DESCRIPTION OF DRAWINGS
