[0004] In view of the above technical defects, a solution is proposed herein. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for fusing all-watershed water service geographic data based on multi-source heterogeneity to solve the above-mentioned technical defects. The present invention initially analyzes from two aspects of the acquisition performance and acquisition accuracy of water service geographic data to ensure the effectiveness and availability of the data, and further analyzes from the perspective of data processing through the way of information feedback to reduce the impact of the data on the subsequent model construction. And through the way of information progression, the water service geographic model construction is tracked and evaluated. On the one hand, the multi-scale modeling process is optimized and managed to improve the modeling efficiency of multi-scale modeling. On the other hand, the actual water service geographic model is repaired to ensure the accuracy of the actual water service geographic model. At the same time, along with the in-depth evaluation and analysis of the dynamic display quality of the model, the dynamic display of the actual water service geographic model is controlled to improve the dynamic display quality of the actual water service geographic model.

[0006] The purpose of the present invention can be achieved by the following technical solutions: A method for fusing all-watershed water service geographic data based on multi-source heterogeneity, comprising the following steps:

[0007] Step 1: Collect the data source risk information and extraction risk information of the information collection device for the target watershed, and substitute the data source risk information and extraction risk information into Step 2 and Step 3 respectively;

[0008] Step 2: Based on the information availability evaluation feedback analysis of the data source risk information in the information progression manner, perform discriminant analysis on the obtained facility evaluation index and acquisition feature index. If a valid signal is obtained, proceed to Step 3; if an interference signal is obtained, output the feedback.

If a normal signal or a risk signal is obtained, output the feedback.

[0010] Step 4: Based on the construction tracking evaluation analysis of the water service geographic model under the normal signal, perform discriminant processing on the obtained fusion evaluation coefficient. If a fusion matching signal or a fusion repair signal is obtained, output the feedback.

[0011] Step 5: Based on the model dynamic display quality evaluation analysis under information fusion feedback, obtain the dynamic display evaluation coefficient, perform discriminant processing on the obtained dynamic display evaluation coefficient, and output the feedback of the obtained stable signal or visual deviation signal.

The model construction duration represents the duration from the start time of multi-scale modeling to the completion time of modeling. Compare and analyze the model construction duration with the preset model construction duration threshold:

[0022] If the model construction duration is less than the preset model construction duration threshold, generate a feedback instruction;

[0023] If the model construction duration is greater than or equal to the preset model construction duration threshold, generate a control signal.

[0024] Preferably, when a feedback instruction is generated, obtain the actual water service geographical model after multi-scale modeling, and at the same time obtain the standard water service geographical model of the target basin.

[0028] Preferably, the number of dynamic picture data corresponding to values ​​lower than a preset threshold value within the dynamic display period is obtained, and the number of dynamic picture data corresponding to values ​​lower than the preset threshold value is set as the dynamic exhibition evaluation value, the dynamic picture data including resolution and saturation; the dynamic evaluation index indicates the number of display defect features that appear in the dynamic display area, and the display defect features include freeze and deformation.

When the interference signal is generated, immediately perform the preset warning operation corresponding to the interference signal, so as to perform targeted control on the abnormal collection device according to the information feedback situation to ensure the effectiveness and availability of the data;

[0046] In the embodiment of the present invention, the facility evaluation index represents the proportion of the number of operation defect features in the total number of collection devices. The operation defect features include over-temperature, high energy consumption, etc. Over-temperature means that the duration for which the device operating temperature exceeds the preset threshold exceeds the preset threshold, and high energy consumption means that the device operating energy consumption value exceeds the threshold.

It should be noted that the larger the value of the extraction operation efficiency value, the lower the data processing efficiency;

[0054] Compare and analyze the error risk value and the extraction operation efficiency value with the preset error risk value threshold and the preset extraction operation efficiency value threshold, and set the number of error risk values and extraction operation efficiency values greater than or equal to the preset error risk value threshold and the preset extraction operation efficiency value threshold as the fusion interference evaluation coefficient, and perform discrimination processing on the fusion interference evaluation coefficient:

[0055] If the fusion interference evaluation coefficient is equal to zero, generate a normal signal;

The model construction duration represents the duration between the start time of multi-scale modeling and the completion time of modeling. Compare and analyze the model construction duration with the preset model construction duration threshold:

When the regulation signal is generated, a preset warning operation corresponding to the regulation signal is immediately performed to optimize the management of the multi-scale modeling process and improve the modeling efficiency of the multi-scale modeling;

[0062] When a feedback instruction is generated, the actual water service geographical model after multi-scale modeling is obtained, and at the same time, the standard water service geographical model of the target basin is obtained.

[0067] In the embodiment of the present invention, the number of values of the dynamic picture data during the dynamic display period that are lower than the preset threshold is obtained, and the number of values of the dynamic picture data that are lower than the preset threshold is set as the dynamic display evaluation value. The dynamic picture data includes resolution, saturation, etc. It should be noted that the larger the value of the dynamic display evaluation value, the worse the display risk of the actual water service geographical model;

[0068] In the embodiment of the present invention, the dynamic evaluation index represents the number of occurrences of display defect features in the dynamic display area. The display defect features include stuttering, deformation, etc. It should be noted that the larger the value of the dynamic evaluation index, the worse the display quality risk of the actual water service geographical model;

[0069] Compare and analyze the dynamic video data and the dynamic evaluation index with the preset dynamic video data threshold and the preset dynamic evaluation index threshold, and set the number of corresponding ones in the dynamic video data and the dynamic evaluation index that are greater than or equal to the preset dynamic video data threshold and the preset dynamic evaluation index threshold as the dynamic display evaluation coefficient, and perform discrimination processing on the dynamic display evaluation coefficient:

[0072] In summary, the present invention initially analyzes from the perspective of water service geographic data collection, that is, analyzes from two points of collection performance and collection accuracy to judge the availability of the collected data, and then controls the abnormal collection equipment according to the information feedback to ensure the effectiveness and availability of the data. And through the information feedback method, further perform quantitative analysis on data processing security supervision from the perspective of data processing, so as to control the processing of multi-source heterogeneous water service geographic data, improve the processing effect of multi-source heterogeneous water service geographic data, and reduce the impact of the data on the subsequent model construction;
