Description

Technical Field

[0001] The present invention relates to the technical field of irrigation engineering, and in particular to an automatic correction method, device and electronic equipment for agricultural irrigation rate in irrigation engineering. Background Art

[0002] Irrigation projects play a vital role in ensuring the basic livelihoods and production of the people. Irrigation projects primarily include water source projects, water transmission and distribution projects, and water storage and regulation projects. Water transmission and distribution projects are the focus of irrigation project construction. However, these projects typically involve long channels (pipes) and large engineering workloads, making their scale the primary factor controlling investment. The design flow of the channels (pipes) determines the scale of the water transmission and distribution projects, while the agricultural irrigation rate is the primary determinant of the design flow. Currently, the agricultural irrigation rate is typically calculated by manually modifying the initial irrigation rate of representative crops at the design guarantee rate according to relevant regulations and specifications. However, this manual modification process is cumbersome, and the results vary from person to person. This results in significant uncertainty in the manually modified agricultural irrigation rate, significantly impacting the calculation efficiency of the irrigation project design flow and the suitability of related design results. This also makes it increasingly difficult to meet the new requirements for economic justification of irrigation projects under the current circumstances. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a method, device and electronic equipment for automatic correction of agricultural irrigation rate of irrigation projects, so as to improve the working efficiency of the agricultural irrigation rate correction link of irrigation projects, thereby helping to improve the calculation efficiency of the design flow of irrigation water supply and distribution projects, and helping to efficiently analyze and fully demonstrate the economic rationality of the construction plan and scale of irrigation water supply and distribution projects.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0016] At present, the agricultural irrigation rate of irrigation projects is generally obtained by manually correcting the initial irrigation rate of representative crops under the design guarantee rate according to relevant regulations and specifications. However, the manual correction process is relatively cumbersome and the results vary from person to person, resulting in great uncertainty in the manual correction of agricultural irrigation rates. This greatly affects the calculation efficiency of the design flow of irrigation projects and the suitability of related design results, and it is becoming increasingly difficult to meet the new requirements for the economic rationality demonstration of irrigation projects under the new situation.

[0017] Based on this, the present invention provides an automatic correction method, device and electronic equipment for the agricultural irrigation rate of irrigation projects, which can improve the working efficiency of the agricultural irrigation rate correction link of irrigation projects, thereby helping to improve the calculation efficiency of the design flow of irrigation water supply and distribution projects, and help to efficiently analyze and fully demonstrate the economic rationality of the construction plan and scale of irrigation water supply and distribution projects.

[0018] To facilitate understanding of this embodiment, firstly, a method for automatically correcting the irrigation rate of agricultural irrigation in an irrigation project disclosed in an embodiment of the present invention is described in detail. Figure 1 As shown, the method for automatically correcting the agricultural irrigation rate of an irrigation project may include the following steps:

[0019] Step S102: Obtain time series data of the net irrigation quota for various representative crops in the irrigation project.

[0020] Among them, representative crops can refer to crops grown in irrigation project areas such as paddy fields, dry land, and gardens.

[0021] The time series data of net irrigation quota may refer to the net irrigation quota data representing the changes of crops year by year and time period over time, which can reflect the law of changes of net irrigation quota of crops over time; the time series data of net irrigation quota is generally calculated in advance using the calendar method, and the calculation period is generally day or ten days.

[0022] Step S104: determining a designed irrigation schedule for each representative crop based on the obtained irrigation net quota time series data and the preset design guarantee rate.

[0023] Among them, the designed irrigation system is the irrigation system of representative crops of the corresponding type in a typical year. The irrigation system mainly includes the number of irrigations, irrigation duration, irrigation date, irrigation quota, irrigation quota, etc.

[0024] The typical year can be any year that meets the design guarantee rate and requires a relatively large irrigation project scale for the irrigation allocation process. For each representative crop, the irrigation schedule of the typical year can be used as the design irrigation schedule for that representative crop. When the determined irrigation schedule is calculated based on a period of more than one day (such as ten days, months, or other days), to facilitate subsequent revisions to the irrigation rate, the determined irrigation schedule can be averaged and discretized into an irrigation schedule based on the number of days in each calculation period.

[0025] Step S106: determining the initial irrigation rate of the irrigation project based on the designed irrigation schedules of various representative crops.

[0026] Among them, the initial irrigation rate changes with time. The initial irrigation rate of the irrigation project can reflect the initial distribution period and initial value of the agricultural irrigation rate of the irrigation project, thereby providing basic data for the subsequent correction of the irrigation rate.

[0027] Step S108: iteratively correct the initial irrigation rate based on the preset correction requirements to obtain the designed irrigation rate of the irrigation project.

[0028] Among them, each time the initial irrigation rate is revised, the rationality of the revised irrigation rate is checked based on the initial irrigation rate and the preset agricultural irrigation data, and the design irrigation rate is the irrigation rate after the rationality check is passed.

[0029] An embodiment of the present invention provides a method for automatically correcting the agricultural irrigation rate of an irrigation project. The method first obtains time-series data on the net irrigation quota for various representative crops in the irrigation project. Then, based on the obtained time-series data and a preset design guarantee rate, a design irrigation schedule for each representative crop is determined. The initial irrigation rate of the irrigation project is then determined based on the design irrigation schedules for the various representative crops. The initial irrigation rate is then iteratively corrected based on preset correction requirements, ultimately obtaining the design irrigation rate for the irrigation project. Using this technique, the initial irrigation rate of the irrigation project can be automatically corrected using the time-series data on the net irrigation quota, the preset design guarantee rate, and the preset correction requirements, ultimately determining the design irrigation rate for the irrigation project. This improves the efficiency of the agricultural irrigation rate correction process in the irrigation project, thereby facilitating the calculation of the design flow rate for the irrigation water supply and distribution project. This facilitates efficient analysis and thorough demonstration of the economic rationality of the construction plan and scale of the irrigation water supply and distribution project.

[0030] As a possible implementation, the designed irrigation schedule may include a designed irrigation quota and a designed irrigation duration for each irrigation of a corresponding type of representative crop in a typical year. Based on this, step S106 (i.e., determining the initial irrigation rate of the irrigation project based on the designed irrigation schedule for each representative crop) may include:

[0031] Step 1: Based on the designed irrigation quota and designed irrigation duration corresponding to various representative crops, determine the first irrigation rate of each representative crop for each irrigation in a typical year.

[0032] Specifically, based on the designed irrigation quota and designed irrigation duration corresponding to various representative crops, the following formula can be used to calculate the first irrigation rate of each representative crop in each irrigation in a typical year:

[0033]

[0034] Among them, q ik is the first irrigation rate of the kth irrigation of the i-th representative crop in a typical year, in m 3 / (s·ten thousand mu); a i is the planting ratio of the i-th representative crop in a typical year, that is, the ratio of the irrigated area of the i-th representative crop to the irrigated area of the irrigation project in the typical year; m ik The design irrigation quota for the kth irrigation of the i-th crop in a typical year, in m 3 / mu; T ik The designed irrigation duration of the kth irrigation of the i-th representative crop in a typical year, in d.

[0035] Step 2: Determine the initial irrigation rate based on the first irrigation rates corresponding to various representative crops in the same target period in a typical year.

[0036] Specifically, for each target period in a typical year, the second irrigation rate of the irrigation project in that target period can be calculated using the following formula based on the first irrigation rate corresponding to various representative crops in that target period:

[0037]

[0038] Among them, q j is the second irrigation rate of the irrigation project in the jth target period in a typical year, in m 3 / (s·ten thousand mu); n represents the number of crop types; q ij is the first irrigation rate of the i-th crop in the j-th target period in a typical year, in m 3 / (s·ten thousand mu);

[0039] The initial irrigation rate is determined based on the second irrigation rate of the irrigation project in each target period.

[0040] As a possible implementation, the above-mentioned net irrigation quota time series data may be time series data of multiple representative years; based on this, the above-mentioned step S104 (i.e., determining the designed irrigation schedule for each representative crop based on the obtained net irrigation quota time series data and the preset design guarantee rate) may include:

[0041] Step A1: Filter out, from the irrigation net quota time series data, at least one target year's time series data in which the actual water usage rate matches the preset design guarantee rate as target time series data.

[0042] Among them, the deviation between the actual water consumption rate in each target year and the preset design guarantee rate is within the preset deviation range.

[0043] Specifically, the net irrigation quota data corresponding to each representative year in the net irrigation quota time series data can be statistically analyzed to obtain the actual water use rate of each representative year, and then the deviation between the actual water use rate of each representative year and the preset design guarantee rate can be calculated, and the representative year with a deviation within the preset deviation range can be taken as the target year, and then the net irrigation quota data corresponding to the target year in the net irrigation quota time series data can be extracted as the target time series data.

[0044] Step A2: Calculate the irrigation quota time series data of each representative crop corresponding to each target year from the target time series data, and determine the irrigation schedule of each representative crop in a typical year based on the obtained irrigation quota time series data.

[0045] The irrigation quota time series data may refer to irrigation quota data representing crops that change over time year by year and time period by time, and may reflect the pattern of changes in irrigation quotas of crops over time.

[0046] Specifically, statistical analysis can be performed on the data corresponding to each target year in the target time series data to obtain the irrigation quota time series data of each representative crop corresponding to each target year, and the dry season irrigation quota and / or flood season irrigation quota of each representative crop corresponding to each target year can be statistically calculated from the irrigation quota time series data. Then, the typical year is determined based on the dry season irrigation quota and / or flood season irrigation quota of each target year, and the irrigation system of each representative crop in the typical year is determined as the corresponding designed irrigation system.

[0047] As a possible implementation, the preset correction requirement may include at least one of the following:

[0048] The ratio between the adjustment value of the designed irrigation duration of the same irrigation and the corresponding designed irrigation duration is not greater than a preset first ratio threshold; wherein the preset first ratio threshold is less than 1;

[0049] The ratio between the adjustment value of the design irrigation quota of the same irrigation and its corresponding design irrigation quota shall not be greater than a preset second ratio threshold, and the design irrigation quota of the same representative crop in two consecutive irrigations shall not be continuously reduced; wherein the preset second ratio threshold is less than 1;

[0050] The number of days for advancing or postponing the irrigation date shall not exceed the preset first day threshold. If the irrigation date of two consecutive irrigations of the same representative crop needs to be changed, the irrigation date of the two consecutive irrigations of the same representative crop shall be advanced or postponed at the same time.

[0051] The maximum irrigation rate within a time range where the cumulative number of days is not less than the preset second number threshold is used as the design irrigation rate; wherein the preset second number threshold is greater than the preset first number threshold;

[0052] The ratio between the corrected irrigation rate and the corresponding designed irrigation rate is not greater than a preset third ratio threshold and not less than a preset fourth ratio threshold; wherein the preset third ratio threshold is greater than 1 and the preset fourth ratio threshold is less than 1;

[0053] During each irrigation period, there shall be no water outage event with a duration less than the preset third-day threshold; wherein the preset third-day threshold is less than the preset second-day threshold;

[0054] The ratio of the irrigated area of each representative crop to the irrigated area of the irrigation project is within the corresponding preset ratio range.

[0055] As a possible implementation, the preset agricultural irrigation data may include preset agricultural planting water use data in a preset area and / or preset design irrigation rate data; based on this, the step of performing a rationality check on the revised irrigation rate based on the initial irrigation rate and the preset agricultural irrigation data each time the initial irrigation rate is revised may include: for each revision of the initial irrigation rate, comparing the revised irrigation rate with the initial irrigation rate and the preset agricultural irrigation data to determine whether the revised irrigation rate is reasonable; if the revised irrigation rate is reasonable, the rationality check of the revised irrigation rate passes; if the revised irrigation rate is unreasonable, adjusting the ratio of the irrigation area of various representative crops to the irrigation area of the irrigation project and re-designing the irrigation system based on the various representative crops to determine the initial irrigation rate of the irrigation project.

[0056] Among them, redetermining the initial irrigation rate of the irrigation project mainly involves redetermining the initial value of the automatic correction process of the initial irrigation rate, thereby affecting the correction process and correction results.

[0057] After each correction of the initial irrigation rate to obtain the irrigation rate, the initial irrigation rate and the preset agricultural irrigation data can be used to check whether the obtained irrigation rate is reasonable, so as to facilitate the re-determination of the initial irrigation rate and the iterative correction of it when the obtained irrigation rate is unreasonable, thereby ensuring that a reasonable design irrigation rate can be corrected in the end.

[0058] For ease of understanding, the operation of the above-mentioned method for automatically correcting agricultural irrigation rates in irrigation projects is described below by taking a specific application as an example.

[0059] See also Figure 2 As shown in the figure, the automatic correction method of agricultural irrigation rate of irrigation area project can be carried out according to the following process:

[0060] Step 1: Determine the designed irrigation schedule for various representative crops.

[0061] Based on the net irrigation quota of various representative crops year by year and time period (i.e., time series data of net irrigation quota), the net irrigation quota data of each year can be statistically analyzed to obtain the actual water use rate of each year. Then, the actual water use rates of all years are sorted from large to small or from small to large, and 2 to 3 years that meet the design guarantee rate (i.e., the difference between the actual water use rate and the design guarantee rate is within a certain range) are selected as target years based on the sorting results. Then, the irrigation distribution process in each target year is statistically analyzed (including statistical irrigation quota, which includes dry season irrigation quota and flood season irrigation quota), and the target year with the most unfavorable irrigation distribution process (i.e., the highest dry season irrigation quota) is selected as the typical year. Then, the irrigation system of various representative crops in the typical year is used as the design irrigation system for various representative crops.

[0062] When the design irrigation system of the selected typical year is in ten-day units, the design irrigation system of the selected typical year can be discretized into a design irrigation system in days according to the following formula:

[0063]

[0064] Where: Q ′ is the irrigation quota for a typical crop year in days, in m 3 / mu; Q is the irrigation quota for a typical crop year in ten-day periods, in m 3 / mu; D represents the number of days in the ten-day period of the crop, with the unit being d, where 10 days are taken for the first and middle ten-day periods, 8 days for the second half of February, and 10 days (corresponding to months with 30 days) or 11 days (corresponding to months with 31 days) for the second half of other months.

[0065] Step 2: Determine the initial irrigation rate of the irrigation project.

[0066] Based on the designed irrigation system of various representative crops (including the irrigation quota and irrigation duration of each irrigation for various representative crops in a typical year), the irrigation rate of each irrigation for various representative crops in a typical year (i.e., the first irrigation rate) is calculated; the first irrigation rates of various representative crops in the same period of the typical year are added together to calculate the initial irrigation rate of the irrigation project, thereby analyzing the maximum, minimum and distribution period of the initial irrigation rate of the irrigation project, which can provide basic data for subsequent irrigation rate corrections.

[0067] In the above step 2, the value of the net irrigation quota for each unit period in a typical year is the irrigation quota for that period. The first irrigation rate calculation formula can be used based on the irrigation quota for that period and the duration of irrigation. Calculate the first irrigation rate of each irrigation of various representative crops in this period; after obtaining the first irrigation rate of each irrigation of various representative crops in each period of a typical year, the formula The initial irrigation rate of each period in a typical year of the irrigation project is calculated.

[0068] Step three: automatically correct the initial irrigation rate of the irrigation project to determine the designed irrigation rate of the irrigation project.

[0069] The initial irrigation rate of the irrigation project is automatically corrected by presetting the irrigation rate correction requirements and performing feedback adjustments. After multiple rounds of automatic corrections, the designed irrigation rate of the irrigation project is obtained.

[0070] In step three above, the preset irrigation rate correction requirements are mainly determined by referring to relevant regulations and specifications of the state and water conservancy departments and making appropriate trade-offs based on actual engineering experience; the feedback adjustment of the irrigation rate correction requirements mainly considers factors such as the actual difficulty, feasibility and accessibility of the irrigation rate correction.

[0071] In the process of automatically correcting the initial irrigation rate of the irrigation project, the irrigation rate correction requirements may include:

[0072] (1) The extension or shortening of the irrigation time shall not exceed 20% of the original irrigation time;

[0073] (2) The adjustment value of the irrigation quota shall not exceed 10% of the original irrigation quota, and the irrigation quota of the same representative crop shall not be reduced twice in a row;

[0074] (3) The number of days that the irrigation date is advanced or postponed shall not exceed 3 days; if the irrigation date of the same representative crop needs to be changed for two consecutive irrigations, it is prohibited to advance the irrigation date of one of the two consecutive irrigations and postpone the irrigation date of the other (that is, it is necessary to ensure that the irrigation date of the two consecutive irrigations that require the irrigation date to be changed is advanced or postponed);

[0075] (4) The maximum irrigation rate accumulated over 30 days is used as the design irrigation rate;

[0076] (5) The short-term peak value of the revised irrigation rate shall not exceed 120% of the design irrigation rate, and the minimum value of the revised irrigation rate shall not be less than 30% of the design irrigation rate;

[0077] (6) The revised irrigation rate avoids short-term water outages of less than 5 days;

[0078] (7) Adjust the planting structure of various representative crops, and the planting ratio adjustment value of each representative crop is within its corresponding specified range.

[0079] The process of automatically correcting the initial irrigation rate of the irrigation project mainly includes:

[0080] First, the first round of automatic correction of the initial irrigation rate of the irrigation project is carried out. If the corrected irrigation rate meets the preset irrigation rate correction requirements (1) to (6), the corrected irrigation rate is the required design irrigation rate. If the corrected irrigation rate cannot meet the preset irrigation rate correction requirements (1) to (6), the corrected irrigation rate is automatically adjusted to only meet the preset irrigation rate correction requirements (1) to (5), and then the first round of automatic correction of the initial irrigation rate of the irrigation project is carried out. If the corrected irrigation rate still cannot meet the preset irrigation rate correction requirements (1) to (5), then the corrected irrigation rate is automatically adjusted again. The automatically adjusted and corrected irrigation rate only needs to meet the preset irrigation rate correction requirements (1) to (4), and then the first round of the third automatic correction of the initial irrigation rate of the irrigation project is carried out; if the corrected irrigation rate still cannot meet the preset irrigation rate correction requirements (1) to (4), the planting structure of various representative crops is adjusted according to the preset irrigation rate correction requirements (7), and then the second round of the first correction of the initial irrigation rate of the irrigation project is started according to the correction method of the first round of the first automatic correction, and so on, until the design irrigation rate that meets the preset irrigation rate correction requirements (1) to (6) is obtained. Table 1 shows the automatic correction cycle process of the initial irrigation rate of the irrigation project.

[0081] The cropping structure refers to the ratio of the irrigated area of a representative crop to the irrigated area of the irrigation project. The cropping structure of each representative crop is primarily based on information such as the agricultural development plan and the development direction of specialty agricultural planting in the region where the irrigation project is located. Adjustments are made within a reasonable range. The direction and value of the cropping structure adjustment are pre-set in the data dictionary for automatic correction. The adjusted comprehensive irrigation quota of the irrigation project does not exceed the water-saving requirements of the comprehensive agricultural water quota for the corresponding region.

[0082] Table 1 Automatic correction flow chart of agricultural irrigation rate in irrigation projects

[0083]

[0084] Step 4: Check the rationality of the irrigation rate designed for the irrigation project.

[0085] The rationality check mainly includes: comparative analysis of the initial irrigation rate and the designed irrigation rate, statistical analysis of whether the correction period, correction value and correction direction of the initial irrigation rate are in line with the regional agricultural water use characteristics and regional agricultural irrigation habits, and analysis of whether the initial irrigation rate is coordinated with the designed irrigation rate results of adjacent areas, similar projects and similar planting structures.

[0086] Specifically, the above step 4 mainly includes the following two aspects:

[0087] (1) Compare and analyze the initial irrigation rate and the design irrigation rate of the irrigation project to determine whether the design irrigation rate has abnormal values (such as incorrect values, values that deviate too much from the initial irrigation rate, etc.), and statistically analyze the correction period, correction value, and correction direction of the initial irrigation rate to test whether the design irrigation rate obtained after correction is consistent with the laws and characteristics of regional agricultural planting water use. If the design irrigation rate of the irrigation project is unreasonable (such as the design irrigation rate has abnormal values, the design irrigation rate does not conform to the laws and characteristics of regional agricultural planting water use, etc.), return to the process of determining and automatically correcting the initial irrigation rate, adjust the representative crop planting structure according to (7) in the preset irrigation rate correction requirements, recalculate the initial irrigation rate, and re-automatically correct the initial irrigation rate according to the correction method of the first round of the first automatic correction in step 3 until the design irrigation rate that meets the preset irrigation rate correction requirements (1) to (6), has no abnormal values, and conforms to the laws and characteristics of regional agricultural planting water use is obtained.

[0088] (2) Compare the design irrigation rate of the irrigation project with the design irrigation rate results of adjacent areas and similar projects, and analyze whether the design irrigation rate of the irrigation project is consistent with the compared design irrigation rate results under similar planting structures. If there is a discrepancy such as a large difference in values, return to the process of determining the initial irrigation rate and automatically correcting it, adjust the representative crop planting structure according to (7) in the preset irrigation rate correction requirements, and re-correct the initial irrigation rate according to the correction method of the first round of the first automatic correction in step 3 until a design irrigation rate that is consistent with the design irrigation rate results of adjacent areas, similar projects, and similar planting structures is obtained.

[0089] In the process of checking the rationality of the irrigation rate designed for the irrigation project, the irrigation rate correction requirements can be continuously adjusted according to actual needs and the irrigation rate can be automatically corrected again using the adjusted irrigation rate correction requirements, so that the irrigation rate correction process can proceed in the direction of obtaining a more reasonable correction result, thereby accelerating the overall process of the agricultural irrigation rate correction link of the irrigation project.

[0090] Different from the traditional method of manually correcting the initial irrigation rate, the above-mentioned automatic correction method of the agricultural irrigation rate of the irrigation project presets the irrigation rate correction requirements and continuously adjusts the irrigation rate correction requirements during the correction process. It creatively combines the steps of determining the design irrigation system, determining the initial irrigation rate, automatically correcting the initial irrigation rate, and analyzing the rationality of the design irrigation rate. It adopts the input-calculation-feedback-calculation-analysis-feedback-calculation-output cyclic optimization model to establish a timely and efficient automated feedback adjustment mechanism for the agricultural irrigation rate correction link of the irrigation project. The correction process and correction results of the irrigation rate are effectively connected with relevant standards and specifications, which greatly accelerates the calculation speed of the agricultural irrigation rate correction link of the irrigation project, thereby greatly improving the calculation efficiency of the design flow of the irrigation area water supply and distribution project, which is conducive to efficient analysis and full demonstration of the economic rationality of the construction plan and scale of the irrigation area water supply and distribution project.

[0091] Based on the above-mentioned method for automatically correcting the agricultural irrigation rate of an irrigation project, the embodiment of the present invention also provides an automatic correction device for the agricultural irrigation rate of an irrigation project, see Figure 3 As shown, the automatic correction device for agricultural irrigation rate of irrigation area engineering may include the following modules:

[0092] The acquisition module 302 can be used to obtain the time series data of the net irrigation quota of various representative crops in the irrigation project.

[0093] The first determination module 304 can be used to determine the design irrigation schedule for each representative crop based on the obtained irrigation net quota time series data and the preset design guarantee rate; wherein the design irrigation schedule is the irrigation schedule for the corresponding representative crop in a typical year.

[0094] The second determination module 306 may be configured to determine an initial irrigation rate for the irrigation project based on designed irrigation schedules for various representative crops.

[0095] The correction module 308 can be used to iteratively correct the initial irrigation rate based on preset correction requirements to obtain the design irrigation rate of the irrigation project; wherein, each time the initial irrigation rate is corrected, the rationality of the corrected irrigation rate is checked based on the initial irrigation rate and preset agricultural irrigation data, and the design irrigation rate is the irrigation rate after the rationality check passes.

[0096] An embodiment of the present invention provides an automatic correction device for the agricultural irrigation rate of an irrigation project, which can use irrigation net quota time series data, a preset design guarantee rate and a preset correction requirement to automatically correct the initial irrigation rate of the irrigation project and then determine the design irrigation rate of the irrigation project. It can improve the working efficiency of the agricultural irrigation rate correction link of the irrigation project, thereby facilitating the improvement of the calculation efficiency of the design flow of the irrigation water supply and distribution project, and helping to efficiently analyze and fully demonstrate the economic rationality of the construction plan and scale of the irrigation water supply and distribution project.
