[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] In an exemplary embodiment, a method for detecting ADCP hydrological test data is provided. Figure 1 As shown, the process includes the following steps 101 to 105.

[0030] Step 101, obtaining multi-flow velocity and direction data on a planned cross-section line during a cruise ADCP hydrological test.

[0031] Step 102, based on the actual section line in the process of the cruise ADCP hydrological test, the section coverage integrity is determined to obtain the section coverage integrity determination result.

[0032] Step 103, determining the proportion of the reverse flow direction on the multi-flow velocity and direction data to obtain a determination result of the proportion of the reverse flow direction.

[0033] Step 104, performing a burst integrity check on the burst flow velocity and flow direction data to obtain a burst integrity check result.

[0034] Step 105, determining the quality of the multi-burst flow velocity and direction data on the planned section line according to the section coverage integrity determination result, the reverse flow direction ratio determination result and the burst integrity determination result.

[0035] The above steps 101 to 105 detect the quality of the ADCP hydrological test field data by calculating and analyzing the compliance of several key indicators, and give a qualified judgment. It is possible to timely judge the quality of the field collected data and give a qualified judgment.

[0036] In another exemplary embodiment, in the above step 101, the ADCP device is a device that collects the flow velocity and direction from the surface layer to the bottom layer by transmitting and receiving sound wave signals. The process of one transmission and reception is referred to as a bang. The flow velocity and direction data of one bang includes the sound wave transmission time, reception time, geographic location information, layered flow velocity data and layered flow direction data, etc. The flow velocity and direction data of each bang output by the ADCP device (hereinafter referred to as bang data) is sent to the designated server through the 4G / 5G RTU (Remote Terminal Unit). After receiving the bang data, the server parses the location, time, flow velocity and direction of each layer of the bang and other information.

[0037] In another exemplary embodiment, in the above step 102, during the underway ADCP hydrographic survey, the survey vessel travels according to the planned section line, and the consistency between the section line length covered by the actual collected bang data (i.e., the length of the actual section line) and the length of the planned section line is called the section coverage integrity, and its calculation method is as follows: Figure 2 As shown, in Figure 2In the figure, line segment AB represents the planned section line, line segment CD represents the actual section line, point E is the projection of point C on line segment AB, and point F is the projection of point D on line segment AB. The calculation formula for section coverage integrity is shown in the following formula.

[0038] .

[0039] in, To ensure the integrity of the cross-section coverage, is the actual length of the section line, The length of the planned section line.

[0040] In another exemplary embodiment, the actual cross-section line can be determined based on the geographical location information in the flow velocity and direction data of each flow, or based on the positioning information of the survey ship. The specific determination method will not be described in detail herein.

[0041] In another exemplary embodiment, the above step 102 may be replaced by the following steps 201 to 203 .

[0042] Step 201, calculating the section coverage completeness according to the planned section line and the actual section line.

[0043] Step 202: If the section coverage integrity is greater than the section coverage integrity threshold, the section coverage integrity determination result is determined to be qualified.

[0044] Step 203: If the section coverage integrity is not greater than the section coverage integrity threshold, the section coverage integrity determination result is determined to be unqualified.

[0045] In another exemplary embodiment, the above step 103 determines the proportion of the countercurrent flow by counting the countercurrent flow. In offshore waters or rivers at the estuary, the direction of the water flow is dominated by the direction of the tide. During the period of high and low tide, the flow direction measured by all the tidal currents in the section should be consistent with the direction of the tide. If it does not meet this rule, the measured field data does not meet the quality requirements. The countercurrent flow statistics method is as follows.

[0046] like Figure 3 As shown in the figure, suppose that the planned section line AB measures the flow velocity and direction data of 7 bangs in total, and each bang has the flow velocity and direction data of six layers from the surface to the bottom layer. The average flow direction Y of bang 1-bang 7 is calculated in turn. 1 , Y 2 , Y 3 , Y 4 , Y 5 , Y 6 , Y 7 .

[0047] The ebb direction of the planned section line AB is known to be α. Taking Peng 1 as an example, if: α-90° ≤ Y 1 ≤ ɑ+90°, then the flow direction of Bang 1 is consistent with the direction of ebb tide, otherwise it is inconsistent. The inconsistency is called countercurrent direction, and the flow directions of Bang 1-Bang 7 are counted in turn.

[0048] The percentage of countercurrent direction bangs to all bangs is counted, which is called the countercurrent direction ratio. If the countercurrent direction ratio threshold is set to 20%, then if the countercurrent direction ratio exceeds 20%, it is determined that the countercurrent direction ratio exceeds the limit.

[0049] In another exemplary embodiment, the above step 103 may be replaced by the following steps 301 to 305 .

[0050] Step 301, calculating the average flow direction of each blast flow velocity and direction data according to the flow direction data of each layer in each blast flow velocity and direction data.

[0051] Step 302, determining that the flow velocity and flow direction data whose average flow direction does not satisfy the following formula is the flow velocity and flow direction data of the countercurrent flow direction.

[0052] .

[0053] in, To plan the ebb tide direction of the cross section, For the The average flow direction of the bang flow velocity data, ; The total number of blasts for flow velocity and direction data.

[0054] Step 303, calculating the proportion of the flow velocity and direction data of the countercurrent direction as the countercurrent direction proportion.

[0055] Step 304: If the reverse flow direction ratio is greater than the reverse flow direction ratio threshold, the reverse flow direction ratio determination result is determined to be unqualified.

[0056] Step 305: If the reverse flow direction ratio is not greater than the reverse flow direction ratio threshold, the reverse flow direction ratio determination result is determined to be qualified.

[0057] In another exemplary embodiment, the above step 104 determines the burst integrity through burst integrity statistics, specifically: each burst flow velocity and direction data is divided into several layers of flow velocity data and flow direction data from the surface layer to the bottom layer, among which, the data valid layers exceeding one-half of the total number of layers are called valid bursts, otherwise they are invalid bursts. The proportion of valid bursts to all bursts in a section is defined as burst integrity, and the proportion of intact bursts in the entire section is not less than 80%, otherwise it is judged as unqualified burst integrity.

[0058] In another exemplary embodiment, the validity judgment of the above-mentioned layer data can be based on indicators such as threshold range, average value, fluctuation, etc. The specific judgment method can be set as needed and will not be elaborated here.

[0059] In another exemplary embodiment, the above step 104 may be replaced by the following steps 401 to 404 .

[0060] Step 401, respectively determine whether the flow velocity data and flow direction data of each layer in each burst flow velocity and direction data are valid.

[0061] Step 402, determining the flow velocity and flow direction data whose valid layers are greater than half of the total number of layers as valid flow velocity and flow direction data.

[0062] Step 403: If the proportion of effective flow velocity and direction data is not less than the burst integrity proportion threshold, the burst integrity determination result is determined to be qualified.

[0063] Step 404: If the proportion of effective flow velocity and direction data is less than the bang integrity proportion threshold, the bang integrity determination result is determined to be unqualified.

[0064] In another exemplary embodiment, the specific implementation method of the above-mentioned step 105 is: if the section coverage integrity judgment result, the reverse flow direction proportion judgment result and the burst integrity judgment result all indicate that they are qualified, then the quality of the multi-burst flow velocity and direction data on the planned section line is determined to be qualified; otherwise, the quality of the multi-burst flow velocity and direction data on the planned section line is determined to be unqualified.
