[0025] See also Figure 1 The present invention provides a remote early warning method for a water conservancy project, comprising the following steps:

[0026] Obtain the measured water level data of each point monitored by several radar probes arranged in an array, and analyze and obtain a water level measurement model;

[0027] Collect the shaking signal of the radar probe to obtain the position movement coordinates of each radar probe at each shaking moment;

[0029] Analyze the position of the preset monitoring points in the real-time water level model, obtain the warning data corresponding to each shaking moment, and output the warning data remotely and issue a warning.

[0030] From the above content, it is not difficult to find that in the remote water level monitoring and early warning process of water conservancy projects, multiple radar probes are arranged in an array in the radar installation area, and the water level data at different locations are monitored by each radar probe. Among them, the water level data includes water level height , flow rate Etc. Specifically, the measured water level data at each location is obtained through the array-arranged radar, and the water level measurement model is established according to the depth coordinates of each location on the underwater ground. During the monitoring process of the radar probe, the radar probe will shake to a certain extent due to wind interference. By collecting the shaking signal of the radar probe when it shakes, and obtaining the position movement coordinates of each radar probe arranged in the array that shakes at the same time at each shaking moment, the position movement coordinates of each radar probe after movement and the water level measurement model composed of the measured water level data are realized, and the original coordinates recorded by the radar probe are modified, that is, the original coordinates are modified to the coordinates after the radar probe moves. And the water level measurement model is modified according to the modification of the original coordinates, so as to obtain the modified real-time water level model. In order to better reflect the water level monitoring situation of the preset monitoring point. By analyzing the water level data of the preset monitoring point in the real-time water level model, the early warning data corresponding to each shaking moment can be obtained more accurately, and the early warning data can be remotely sent to, for example, the water conservancy project management office, and it can also be realized in, for example, the water level height and flow rate When the upper threshold is reached, the control output alarm is activated. Through the monitoring and remote warning of water level data of the water conservancy project in the above manner, when the radar probe is shaken by factors such as strong wind, the radar probe can remotely report relatively accurate water level, flow rate and other water level data to the water conservancy project management office.

[0033] Furthermore, a water level measurement model is established, including: the bottom of the water level measurement model is aligned with the measured coordinates of the underwater ground. Simulate; the top of the water level measurement model is measured by each radar probe In the original coordinates Corresponding measured water level data The prediction simulation is performed for the framework vertex; among them, the bottom area of ​​the simulated water level measured model The area formed by the maximum moving distance of the radar probe arranged in the array during the shaking process .

[0034] In one embodiment of the present invention, according to each radar probe The original coordinates of and the underwater ground coordinates of the corresponding position , and the shaking time Measured water level data under When establishing a water level measurement model, it is necessary to simulate the water surface of the water level measurement model, that is, the top situation, and the bottom of the water level measurement model, that is, the underwater ground situation. The side surface can be based on the vertical sections of the water surface and the bottom surface. Specifically, when establishing the underwater ground of the water level measurement model, the coordinates of each point on the underwater ground are pre-determined as the measured coordinates. , input into the water level measurement model to simulate the underwater ground layout. When establishing the top of the water level measurement model, In the original coordinates and through various radar probes Monitor the actual water level data The water surface height coordinates in the water level measurement model are input into the water level measurement model, and then the corresponding radar probe is used to The coordinates of each point on the water surface are used to perform a prediction simulation on the top of the water level measurement model, and then the water level measurement model is obtained. In addition, in order to ensure that the bottom of the simulated water level measurement model can completely cover the radar probe above it The bottom area of ​​the simulated water level measured model The area should be larger than the maximum moving distance of the radar probe in the array arrangement during shaking. .

[0035] Specifically, the top of the water level measurement model is connected to each radar probe. In the original coordinates Corresponding measured water level data Perform prediction simulation for the frame vertex, including: obtaining the water surface coordinates corresponding to two adjacent original coordinates and The height difference between , and based on the current two water surface coordinates and Corresponding flow rate and , the water surface coordinates are obtained through the water level data prediction model based on height difference data and flow velocity and The water level data change curve formed between , the adjacent water level data change curves Smoothly connect them to form a water level data change surface , that is, the top of the water level measured model is predicted.

[0037] It should be noted that the water level data prediction model is obtained by model training based on big data of different height difference data and corresponding different flow rates, as well as corresponding water level data change curves and water level data change surfaces.

[0038] Furthermore, the shaking signal of the radar probe is collected to obtain the position movement coordinates of each radar probe at each shaking moment, including: collecting the overall displacement signal of the radar probes arranged in the array to obtain the unit shaking moment The corresponding array arrangement of radar probes relative to the last shaking moment The overall displacement value , among which, when When the radar probes arranged in the array are at their original coordinates .

[0039] In one embodiment of the present invention, when obtaining the position movement coordinates corresponding to each shaking moment according to the shaking signal of the radar probe, after obtaining the overall movement signal of all radar probes arranged in the array, due to the uncontrollability of wind interference, the position movement coordinates corresponding to each unit shaking moment are obtained. The overall moving distances of all radar probes in the corresponding array are different. Therefore, the shaking time of each unit is obtained by positioning Relative to the last shaking moment The overall displacement value , after a unit shaking time The superposition and The original coordinates of each radar probe in the array arrangement at , and then we can further calculate the shaking time The original coordinates of the distance radar probe The displacement situation.

[0040] Specifically, the position movement of each radar probe can be obtained in real time by installing a positioning sensor on the remote monitoring equipment where the radar probe is installed.

[0041] Furthermore, according to the position movement coordinates of each radar probe after movement and the water level measurement model, the position movement coordinates are controlled to modify the original coordinates of each radar probe corresponding to the water level measurement model, including: according to the overall displacement value , get each shaking time The original coordinates of each radar sensor relative to the array layout The position of the moving coordinates , find the original coordinates At every shaking moment Measured water level data under , get the measured water level data The corresponding water surface Direction coordinate value , the measured water level data The coordinates of the radar probe are changed to position movement coordinates , the measured water level data The monitored water surface coordinates are modified to , and the underwater ground coordinates corresponding to the bottom of the water level measurement model Modified to ,in, Indicates when and The measured coordinates of the bottom of the water level measurement model corresponding to of Direction coordinate value .

As the coordinates of the top points of the real-time water level model, As the coordinates of each underwater ground point at the bottom of the real-time water level model, the corresponding shaking time is obtained Real-time water level model.

[0045] Furthermore, the positions of the preset monitoring points in the real-time water level model are analyzed to obtain the early warning data corresponding to each shaking moment, including: judging whether the monitoring coordinates corresponding to the preset monitoring points at each moment are the same as the real-time coordinates of each radar probe in the real-time water level model; if they are the same, the actual water level data monitored by the corresponding radar probe is controlled to be used as early warning data; if they are not the same, the predicted value of the real-time water level model is controlled to be output as early warning data.

That is, when the two are the same, the measured water level data monitored by the corresponding radar probe is used as warning data. If they are not the same, it means that completely accurate warning data cannot be obtained, and the predicted value of the water level situation of the real-time water level model is controlled to be output as warning data, thereby ensuring the accuracy of the obtained warning data and avoiding blind trust in the warning data.

[0047] Preferably, it is determined whether the monitoring coordinates corresponding to the preset monitoring points at each time are the same as the real-time coordinates of each radar probe in the real-time water level model. If they are the same, the actual water level data monitored by the corresponding radar probe is controlled to be used as early warning data. If they are not the same, the predicted value of the real-time water level model is controlled to be output as early warning data, including: determining the monitoring coordinates of the preset monitoring points Is there a corresponding time for each shake?

[0048] In one embodiment of the present invention, when determining the early warning data, the monitoring coordinates of the selected preset monitoring point are Finally, at each shaking moment, the monitoring coordinates of the preset monitoring points need to be determined in real time. Is there a correlation with each shaking moment? The displacement coordinates of each radar probe If the same situation exists, the control directly outputs the displacement coordinates of the radar probe with the same position coordinates Corresponding water surface coordinates and measured water level data As early warning data. If it does not exist, it means that the early warning data has a certain predictive value. Then the monitoring coordinates will be calculated. Displacement coordinates of each radar probe The distance data between , and further determine the distance data The minimum value in Based on the point coordinates between the radar probes in the array, the displacement coordinates of the radar probe closest to the preset monitoring point can be determined. The maximum offset distance . Then we get the prediction accuracy When outputting warning data, the top coordinates of the real-time water level model will be Corresponding predicted water level data And the predicted water level data The prediction accuracy The water level data is transmitted to the water conservancy project processing department. , predict water level data When various data in the system exceed the upper limit of the warning threshold set by each system, a remote warning will be issued.
