Description

Technical Field

[0001] The present invention relates to the technical field of weather radar operation evaluation, and more specifically, to a weather radar mode switching evaluation method, system, device and storage medium. Background Art

[0002] Weather radar is the main tool for monitoring and warning of severe convective weather. Its working principle is to emit a series of pulsed electromagnetic waves and use the scattering and absorption of electromagnetic waves by precipitation particles such as clouds, rain and snow to detect the spatial distribution and vertical structure of precipitation, and use this as a warning and tracking precipitation system.

[0003] When a new generation of weather radar is installed in a designated area, the working parameters are the default parameters. For example, the threshold for switching multiple observation modes is the default threshold. Due to the development and changes of the meteorological environment and the differences between regions, the threshold used may not be the optimal value. There may be large deviations in the working time for switching multiple observation modes. It is necessary to find a better value or optimal value for the threshold for switching multiple observation modes.

[0004] However, there is currently a lack of effective methods to evaluate the multi-observation mode switching of newly installed weather radars and to conduct statistical analysis on the rationality of each threshold. Summary of the invention

[0091]

[0092] Table 3

[0093] The basic data transmission timeliness evaluation process includes the following steps:

[0094] Step 21. Get the end time t4 and the start time t3;

[0095] Step 22. Calculate the base data volume scanning period:

[0096] t5 = t4 - t3;

[0097] Step 23. Calculate the actual number of generated data n5 according to the basic data scanning cycle, calculate the number of generated data n6 according to the business promotion scanning cycle t6, and calculate the basic data transmission rate:

[0098] n5=24×60×60 / t5;

[0099] n6=24×60×60 / t6;

[0100]

[0101] Step 24. Generate a second evaluation file according to the set format using the end time t4, the start time t3, and the base data transmission rate;

[0102] Step 25: Upload the second evaluation file to a superior department or the manufacturer of the weather radar system.

[0103] The second evaluation file is a word document, and the data is recorded in the form of a table. Of course, in other embodiments, the second evaluation file can also be an excel document.

[0104] The observation modes of the basic data transmission timeliness evaluation process include three types: VCP11(D), VCP21(D), and VCP31(D). The body scanning cycles are shown in Table 4.

[0105] Serial number Mode Number Body scan cycle 1 VCP11(D) 6 minutes 2 VCP21(D) 6 minutes 3 VCP31(D) 10 minutes

[0106] Table 4

[0107] Take VCP11D as an example. Figure 3 shown.

[0108] In the log "modeswitch_20240919.log", read "2024-09-19 23:31:24Site=Z9774,Task=VCP11D,Time=15:25:57Z[1726759557]," and the VCP11D start running time in this line is 1726759557. Read "2024-09-19 23:37:28Site=Z9774,Task=VCP11D,Time=15:32:01Z[1726759921]," and the VCP11D end time in this line is 1726759921. Subtract the start time from the end time to obtain the time to generate the base data body scan cycle.

[0109] Calculate the base data volume scanning cycle:

[0110] 1726759921-1726759557=364

[0111] The resulting base data volume scanning cycle of 364 seconds is 4 seconds longer than the volume scanning cycle of 360 seconds for business promotion.

[0112] The assessment lasts 24 hours a day, 60 minutes an hour, and 60 seconds a minute. 24*60*60 / 360=240, and a total of 240 VCP11D model base data are generated.

[0113] During the evaluation, 24*60*60 / 364≈237 VCP11D mode base data are generated.

[0114] Transmission rate: 237 / 240*100%≈98.9%

[0115] Conclusion: The radar operates non-stop with a maximum transmission rate of 98.9%.

[0116] The process of evaluating the matching degree between the operating model and the live weather includes the following steps:

[0117] Step 31. Obtain the time t1 when heavy rainfall occurs and the time t2 when heavy rainfall does not occur;

[0118] Step 32: The operation time of the VCP11 (D) mode during the period t1 when heavy precipitation occurs is recorded as m1, and the operation time of the VCP21 (D) or VCP31 (D) mode during the period t2 when no heavy precipitation occurs is recorded as m2;

[0119] Step 33. Calculate the matching degree between mode switching and live weather:

[0120]

[0121] Step 34. The matching degree is counted from 0 to 12 o'clock and from 12 o'clock to 24 o'clock, and is counted every 12 hours. Figure 2 As shown, a third evaluation file is generated according to the set format;

[0122] Step 35. Upload the third evaluation file to the superior department or the manufacturer of the weather radar system.

[0123] The third evaluation file is a word document, and the data is recorded in the form of a table, as shown in Table 5. Of course, in other embodiments, the third evaluation file may also be an Excel document.

[0127] The matching evaluation process between the operation mode and the real-time weather also includes obtaining the time variation pattern of the operation mode. Specifically, the log file of the weather radar system in the evaluation period is read; the log file is parsed, and the automatic operation mode date, time period, current mode, start time, end time, and total duration are read, and a table of time variation patterns of the operation mode (as shown in Table 6) and a statistical chart of radar mode duration (as shown in Table 7) are prepared.

A weather radar mode switching evaluation system, characterized in that: include: A reading module is used to read the log files of the weather radar system during the evaluation period; The parsing module is used to parse the log file when the weather radar system operates in the intelligent prompt + manual switching mode, and read the automatic statistical station number, the intelligent prompt time, the original mode, the recommended switching mode, whether the forecaster confirms the switch, the radar execution switching time, the number of switches to be switched n, the number of confirmed switches n1, and the number of radar execution switches n2; Calculation module, used to calculate the switching correctness: Calculate the confirmation switching success rate: When the weather radar system operates in the intelligent automatic switching mode, the log file is parsed, and the automatic statistical station number, the original mode prompt time, the original mode, the recommended switching mode, the automatic switching mode, the radar execution switching time, the automatic switching number n3, and the successful switching number n4 are read; the automatic switching success rate is calculated; Generate an evaluation file module, which is used to generate a first evaluation file according to a set format for the automatic statistical station number, intelligent prompt time, original mode, recommended switching mode, whether the forecaster confirms the switch, and the radar execution switching time. When the weather radar system operates in the intelligent prompt + manual switching mode, the switching correctness and the confirmed switching success rate are written into the first evaluation file. When the weather radar system operates in the intelligent automatic switching mode, the automatic switching success rate is written into the first evaluation file; The uploading module is used to upload the first evaluation file to the superior department or the manufacturer of the weather radar system.

9. A computer device comprising a memory and a processor, wherein the memory stores a computer program, wherein: When the processor executes the computer program, the weather radar mode switching evaluation method described in any one of claims 1 to 7 is implemented.

10. A computer-readable storage medium having a computer program stored thereon, characterized in that: When the computer program is executed by a processor, a weather radar mode switching evaluation method according to any one of claims 1 to 7 is implemented.
