Description

Technical Field

[0001] The present invention relates to the field of agricultural irrigation, and in particular to a method and system for regulating water levels in stages of a growth pattern. Background Art

[0002] With the continuous advancement of agricultural modernization, precision irrigation technology has become an important means to improve crop production efficiency and optimize water resources management. How to scientifically and effectively regulate the water level in rice fields has become a technical problem that needs to be solved urgently in the agricultural field.

[0003] At present, traditional water level control methods often use artificial irrigation or automated mechanical irrigation to transport water to rice fields, and use artificial diversion channels or drainage pumps to drain rice fields.

[0004] Although the above methods can complete the regulation of the water level of the rice field, the time interval for manual regulation of the water level of the rice field is long, and the water level of the rice field cannot be regulated in time. In addition, most automated mechanical irrigation systems rely on fixed water level settings or a single irrigation mode, and lack the ability to adjust the water level of the rice field in real time according to the growth trend of the rice. Therefore, an automated water level intelligent regulation method is urgently needed to achieve phased regulation of the water level of the rice field, ensure that the water level of the rice field is in the optimal state, and provide the most suitable growth conditions for rice.

[0075] To solve the problems described in the background art, the present invention receives a water level regulation instruction and confirms the target paddy field based on the water level regulation instruction. The target paddy field includes: paddy field land, a water storage reservoir, a water conveyance pipeline, and a drainage pipeline.

[0081] The realization, functional characteristics, and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the accompanying drawings. Specific embodiments

[0082] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0083] The embodiments of the present application provide a stage water level regulation method for the growth trend. The execution subject of the stage water level regulation method for the growth trend includes, but is not limited to, at least one of electronic devices such as a server, a terminal, etc. that can be configured to execute the method provided by the embodiments of the present application.

The server includes, but is not limited to: a single server, a server cluster, a cloud server, or a cloud server cluster, etc.

[0084] Refer to Figure 1 As shown, this is a flowchart of the stage water level regulation method for the growth trend provided by an embodiment of the present invention. In this embodiment, the stage water level regulation method for the growth trend includes:

[0085] S1. Receive a water level regulation instruction, and confirm the target paddy field based on the water level regulation instruction. Among them, the target paddy field includes: paddy field land, a water storage reservoir, a water conveyance pipeline, and a drainage pipeline. Among them, the water conveyance pipeline includes: a water conveyance gate and a water conveyance flow rate meter, and the drainage pipeline includes: a drainage gate and a drainage flow rate meter. Among them, the initial states of both the water conveyance gate and the drainage gate are closed states, and both the water conveyance gate and the drainage gate are treated with double-ring waterproofing.

[0086] It is understandable that the water level regulation instruction is generally initiated by the staff of the farm. Exemplarily, Xiao Zhang is a staff member of a certain farm. Currently, rice is planted in multiple paddy fields on this farm. In order to automatically regulate the water level of a paddy field where rice is planted, the water level regulation instruction is thus initiated. Since each paddy field among the multiple paddy fields has a corresponding number, and the water level regulation instruction contains the number information of the paddy field, the corresponding paddy field can be confirmed through the water level regulation instruction. The paddy field where rice is planted is the paddy field for rice cultivation. The target paddy field is a paddy field for rice cultivation equipped with a water storage reservoir, a water conveyance pipeline, and a drainage pipeline.

[0087] It should be explained that both the water conveyance pipeline and the drainage pipeline are connected to the paddy field for rice cultivation, and the water storage reservoir is connected to the water conveyance pipeline. The main function of the water conveyance pipeline is to serve as a channel for the water storage reservoir to convey water to the paddy field for rice cultivation. The main function of the drainage pipeline is to serve as a channel for the water in the paddy field for rice cultivation to flow out of the paddy field under the action of gravity. And both the water conveyance pipeline and the drainage pipeline are water pipes with a radius greater than 10 cm. The water conveyance pipeline includes a water conveyance gate, and the drainage pipeline includes a drainage gate. The main function of the water conveyance gate is to control the opening and closing of the water conveyance pipeline. When the water conveyance gate is opened, the water in the water storage reservoir will flow through the water conveyance pipeline to the paddy field for rice cultivation, thereby raising the water level of the paddy field for rice cultivation. When the water conveyance gate is closed, the water conveyance pipeline is also closed, blocking the water in the water storage reservoir from flowing to the paddy field for rice cultivation. The main function of the drainage gate is to control the opening and closing of the drainage pipeline. When the drainage gate is opened, the water in the paddy field for rice cultivation will flow out through the drainage pipeline under the action of gravity, thereby lowering the water level of the paddy field for rice cultivation. When the drainage gate is closed, the drainage pipeline is also closed, blocking the water in the paddy field for rice cultivation from flowing out. The main function of the water flow velocity monitor is to monitor the water flow velocity in the water conveyance pipeline, and the main function of the drainage pipeline is to monitor the water flow velocity in the drainage pipeline.

[0088] Importantly, the double - loop waterproof treatment means using a soft rubber ring to surround the edges of the water conveyance gate and the drainage gate, and then using a hard rubber ring to surround the soft rubber ring. Thus, when the water conveyance gate and the drainage gate are completely closed, the gaps between the water conveyance gate and the water conveyance pipeline and between the drainage gate and the drainage pipeline are completely filled with the hard rubber ring and the soft rubber ring, thereby preventing water from flowing out through the gaps between the gate and the pipeline. Among them, the soft rubber ring is a sealing ring made of rubber, and the hard rubber ring is a sealing ring made of polytetrafluoroethylene.

[0089] S2. Confirm the paddy field monitoring agency. Among them, the paddy field monitoring agency includes: a water level detector, a light sensor, a temperature sensor, and a soil humidity sensor.

[0090] It should be understood that the soil moisture sensors are deployed in the soil of the paddy field, and the water level detector, temperature sensor and light sensor are deployed above the water surface of the paddy field. When it is confirmed that the water level detector, light sensor, temperature sensor and soil moisture sensor are all installed in the paddy field, it is confirmed that the paddy field monitoring mechanism is constructed.

[0091] It should be explained that the paddy field monitoring mechanism is a device integrating a water level detector, a light sensor, a temperature sensor and a soil moisture sensor. The water level detector is a sensor used to monitor the field water level of the paddy field. The light sensor is a sensor used to monitor the field light intensity of the paddy field. The temperature sensor is a sensor used to monitor the field temperature of the paddy field. The soil moisture sensor is a sensor used to monitor the field humidity of the paddy field. Among them, after taking the average height of the soil in the field as the reference plane, the field water level is the elevation of the water surface in the paddy field relative to this reference plane. The field light intensity refers to the light intensity of the sunlight received at the position where the light sensor is located in the paddy field. The temperature sensor refers to the air temperature at the position where the temperature sensor is located in the paddy field. Optionally, a DX-WLX-1 high-frequency radar water level gauge is used as the water level detector.

[0092] It should be understood that the technology of the water level detector monitoring the field water level of the paddy field is an existing technology. For example: if the elevation of the water level detector relative to the reference plane during installation is 1m, the water level detector sends high-frequency pulse microwaves to the water surface of the paddy field and receives the reflected microwaves, then the distance between the water level detector and the water surface can be measured. If the distance between the water level detector and the water surface is 0.9m, then the field water level is 1m - 0.9m = 0.1m.

[0093] S3. Obtain the current date, use the water level detector to obtain the starting water level of the paddy field, confirm the optimal water level based on the current date, start recording time starting from the time when the optimal water level is confirmed, and obtain the regulation time.

[0094] It should be explained that the current date refers to the current date. The starting water level is the field water level when the current date is obtained.

[0095] Exemplarily, if the time when the optimal water level is confirmed is 12:00 on May 10th, then start recording time starting from 12:00 on May 10th. When it is 13:00 on May 10th, the regulation time is 1 hour.

[0096] Specifically, the confirmation of the optimal water level based on the current date includes:

[0097] Calculate the number of planting days according to the current date and the preset initial date. Among them, the number of planting days is the absolute difference between the current date and the initial date;

[0098] Calculate the optimal water level based on the planting days and the preset stage days. The calculation formula is as follows:

[0099]

[0100] Where S best is the optimal water level, Day x and Day 0 are the planting days and the stage days respectively, S 0 is the preset initial standard water level, and e is the natural constant.

[0101] It should be explained that the initial date refers to the date of rice transplanting, and the specific date of rice transplanting is determined by the staff of the farm.

[0102] Exemplarily, on May 1st, a batch of rice transplanting was completed in the paddy field, then the initial date is May 1st. If the current date is May 10th, then the planting days are 9 days.

[0103] It should be explained that the optimal water level refers to the most suitable water level in the paddy field for growing rice at the current date. The stage days are values artificially set by the staff of the farm according to the growth law of rice. Preferably, the stage days are 90 days. The standard water level is a value artificially set by the experts of the farm according to the growth law of rice. Preferably, the standard water level is 10 cm.

[0104] It should be understood that according to the general growth law of rice, from the transplanting stage to the booting stage of rice, the required optimal water level will continuously increase, while from the booting stage to the filling stage, the required optimal water level will continuously decrease. Therefore, generally, the number of days experienced from the start of the transplanting stage to the end of the booting stage of rice is set as the stage days. Therefore, in the calculation formula of the optimal water level, when the planting days are less than the stage days, the closer the planting days are to the stage days, the higher the optimal water level; when the planting days are greater than the stage days, the greater the planting days are than the stage days, the lower the optimal water level.

[0105] S4. Compare the starting water level with the optimal water level.

[0106] S5. If the starting water level is greater than the optimal water level, calculate the stage adjustment water level and the initial adjustment water level based on the current date, the starting water level, the optimal water level and the pre-constructed paddy field water level coefficient, and perform an intelligent drainage operation on the paddy field in the target paddy field based on the regulation time, the stage adjustment water level, the initial adjustment water level and the drainage pipeline to obtain the drained field.

[0107] Specifically, before calculating the stage adjustment water level and the initial adjustment water level based on the current date, the starting water level, the optimal water level and the pre-constructed paddy field water level coefficient, it further includes:

[0108] Use a water level detector to obtain the initial water level of the paddy field, confirm the test date, take the time when the initial water level of the paddy field is obtained as the starting point and record the time in real time to obtain the test time;

[0109] When the test time reaches the preset single-day termination time, use the water level detector to obtain the updated water level of the paddy field, and calculate the test water level difference using the updated water level and the initial water level. Among them, the test water level difference is the absolute difference between the updated water level and the initial water level;

[0110] Integrate the test date and the test water level difference into a water level data packet, and store the water level data packet in a pre-constructed water level database to obtain a reference database;

[0111] Confirm the number of data packets in the reference database, and compare the number of data packets with the preset data threshold;

[0112] If the number of data packets is greater than or equal to the data threshold, extract multiple water level data packets from the water level database; otherwise, use the reference database as the water level database, and return to the step of using the water level detector to obtain the initial water level of the paddy field until the number of data packets is greater than or equal to the data threshold;

[0113] Calculate the paddy field water level coefficient based on multiple water level data packets.

[0114] It should be understood that in the embodiment of the present invention, by testing the relationship between precipitation and the water level of the field before rice planting, the paddy field water level coefficient is calculated, which is convenient for subsequent drainage of the paddy field according to the predicted precipitation and the paddy field water level coefficient in stages.

[0115] It should be explained that the initial water level is the water level of the paddy field before rice planting. The test date refers to the date when the initial water level of the paddy field is obtained. The single-day termination time is 24 hours.

[0116] It can be understood that the integration of the test date and the test water level difference into a water level data packet means that the test date and the test water level difference are saved as data in the data packet, and the data packet storing the test date and the test water level difference is the water level data packet. The water level database is a database for storing water level data packets.

[0117] Exemplarily, if the time to obtain the initial water level of the paddy field is 8:00 on March 1st, the test date is March 1st, and starting from 8:00 on March 1st, the time is recorded in real-time. When it is 9:00 on March 1st, the test time is 1 hour. Since the single-day end time is 24 hours, when it is 9:00 on March 2nd, the updated water level of the paddy field is obtained using a water level detector. If the updated water level is 10 cm and the initial water level is 8 cm, the measured water level difference is 2 cm. The pair (2 cm, March 1st) is saved as data in the water level data packet, and the water level data packet is stored in the water level database to obtain a reference database. If the data threshold is 20, since there is only 1 water level data packet in the target of the reference database, the number of data packets is less than the data threshold. So, the step of obtaining the initial water level of the paddy field using the water level detector is returned. Since 24 hours have passed, that is, the initial water level is obtained again on March 2nd, and the updated water level is obtained again on March 3rd. If the measured water level difference calculated again is 1 cm, the pair (1 cm, March 2nd) is saved as data in the water level data packet, and the water level data packet is stored in the water level database. At this time, there are 2 water level data packets in the reference database, and the number of data packets is still less than the data threshold. So, the loop is performed again, and so on, until there are 20 water level data packets in the reference database, and 20 water level data packets are extracted from the reference database.

[0118] Specifically, calculating the paddy field water level coefficient based on multiple water level data packets includes:

[0119] Extracting multiple test dates and multiple measured water level differences from multiple water level data packets, and confirming multiple daily precipitation amounts based on the multiple test dates. Among them, the measured water level difference corresponds one-to-one with the test date, and the daily precipitation amount corresponds one-to-one with the test date;

[0120] Perform the following operations on each measured water level difference among the multiple measured water level differences

[0121] Calculate the initial water level coefficient using the measured water level difference. The calculation formula is as follows:

[0122]

[0123] where, k f is the initial water level coefficient, S f is the measured water level difference, and Pre is the daily precipitation amount corresponding to the measured water level difference;

[0124] Summarize the initial water level coefficients to obtain multiple initial water level coefficients, and calculate the paddy field water level coefficient based on the multiple initial water level coefficients. Among them, the paddy field water level coefficient is the average value of the multiple initial water level coefficients.

[0125] It should be noted that since each water level data packet among multiple water level data packets stores a test date and a measured water level difference, multiple test dates and multiple measured water level differences can be extracted from the multiple water level data packets. The confirmation of multiple daily precipitation amounts based on multiple test dates means: querying the precipitation amount corresponding to each test date among the multiple test dates from the Central Meteorological Observatory and summarizing the precipitation amounts corresponding to each test date to obtain multiple daily precipitation amounts. Exemplarily, if the multiple test dates are respectively: March 1st, March 2nd... March 20th, then query the precipitation amount on March 1st, the precipitation amount on March 2nd... the precipitation amount on March 20th from the Central Meteorological Observatory, and finally obtain 20 daily precipitation amounts. The initial water level coefficient reflects the influence of precipitation on the field water level. When the precipitation amount is fixed, the larger the initial water level coefficient, the greater the influence of precipitation on the field water level, and the higher the height the field water level rises under the action of rainfall.

[0126] Specifically, the calculation of the stage adjustment water level and the initial adjustment water level according to the current date, the starting water level, the optimal water level, and the pre-constructed paddy field water level coefficient includes:

[0127] Confirm the predicted precipitation amount based on the current date, calculate the precipitation fluctuation water level according to the predicted precipitation amount and the paddy field water level coefficient, where the precipitation fluctuation water level is the product of the paddy field water level coefficient and the predicted precipitation amount;

[0128] Calculate the stage adjustment water level according to the precipitation fluctuation water level and the single-day termination time, and the calculation formula is as follows:

[0129]

[0130] where, S l is the stage adjustment water level, t day is the single-day termination time, t jd is the preset stage time threshold, S LX is the precipitation fluctuation water level;

[0131] Calculate the initial adjustment water level according to the starting water level and the optimal water level, where the initial adjustment water level is the absolute difference between the starting water level and the optimal water level.

[0132] Exemplarily, if the current date is May 10th, confirm the predicted precipitation amount by querying the precipitation forecast of the Central Meteorological Observatory on May 10th. If the precipitation forecast shows that the precipitation amount from May 10th to May 11th is 10 mm, then the predicted precipitation amount is 10 mm.

[0133] It should be explained that the precipitation fluctuation water level refers to the total height of the water level rise in the paddy field within 24 hours when the paddy field is affected by rainfall. Preferably, the stage time threshold is 2 hours. The stage-adjusted water level reflects the height of the water level rise in the paddy field within the stage time threshold when the paddy field is affected by rainfall.

[0134] It should be understood that in the subsequent intelligent drainage process, the drainage is divided into two stages. The first drainage stage is to perform one-time drainage to first adjust the starting water level to the optimal water level. The second drainage stage is to perform staged multiple drainages, that is, to drain water every 2 hours to ensure that the water level in the field is always near the optimal water level. Therefore, in the embodiment of the present invention, by calculating the initial adjusted water level and by predicting the precipitation in advance to confirm the stage-adjusted water level, the specific water level to be adjusted in each stage is accurately provided for the subsequent intelligent drainage operation.

[0135] Importantly, the reason why the embodiment of the present invention adopts staged drainage instead of using a water level detector to monitor the water level in real time for real-time drainage is that during the drainage process, the change of the water level in the field has hysteresis, and during drainage, the water level in the field will fluctuate up and down due to the flow of water, the interference of the wind, and the impact of raindrops on the water surface. Therefore, it is unrealistic to monitor the water level in the field in real time during the drainage process, and there will be a large error. Therefore, in the embodiment of the present invention, by calculating the initial adjusted water level and the stage-adjusted water level, and then calculating the initial drainage volume and the stage drainage volume in the subsequent process, the accurate drainage volume is confirmed in advance, so that it is not necessary to monitor the water level in the field in real time during the drainage process, and it can also ensure that the water level in the field is basically maintained near the optimal water level.

[0136] Specifically, the intelligent drainage operation is performed on the paddy field in the target paddy field based on the regulation time, the stage-adjusted water level, the initial adjusted water level, and the drainage pipeline to obtain the drained field, including:

[0137] Obtain the field area of the paddy field, and calculate the initial drainage volume according to the field area and the initial adjusted water level, where the initial drainage volume is the product of the initial adjusted water level and the field area;

[0138] Calculate the stage drainage volume according to the field area and the stage-adjusted water level, where the stage drainage volume is the product of the stage-adjusted water level and the field area;

[0139] Obtain the drainage pipe radius of the drainage pipe, open the drainage gate in the drainage pipe to obtain the target drainage pipe, use the target drainage pipe to drain the paddy field, and use the drainage flow velocity meter to obtain the drainage flow velocity when the target drainage pipe drains the paddy field. Start recording time in real time starting from the time when the drainage gate in the drainage pipe is opened to obtain the drainage time. Calculate the estimated drainage time based on the drainage pipe radius, drainage flow velocity, and initial drainage volume. When the drainage time reaches the estimated drainage time, perform a safety closing operation on the drainage gate in the target drainage pipe to obtain the target closing gate, and confirm the relay drainage pipe and update the drained field based on the target closing gate, target drainage pipe, and paddy field;

[0140] Calculate the stage drainage time based on the drainage pipe radius, drainage flow velocity, and stage drainage volume;

[0141] When it is confirmed that the drainage time reaches the stage time threshold, open the target closing gate in the relay drainage pipe to obtain the updated drainage pipe, use the updated drainage pipe to drain the updated drained field, start recording time in real time starting from the time when the target closing gate in the drainage pipe is opened to obtain the updated drainage time. When the updated drainage time reaches the stage drainage time, perform a safety closing operation on the target closing gate in the updated drainage pipe to obtain the stage closing gate, and confirm the stage drainage pipe and stage drained field based on the stage closing gate, updated drainage pipe, and updated drained field;

[0142] Take the stage drained field as the updated drained field, take the updated drainage time as the drainage time, take the stage closing gate as the target closing gate, take the stage drainage pipe as the relay drainage pipe, and return to the step when it is confirmed that the drainage time reaches the stage time threshold until the regulation time reaches the single - day termination time, and then take the stage drained field as the drained field.

[0143] It should be explained that the field area refers to the area of the paddy field. The drainage pipe radius refers to the radius of the drainage pipe. The initial drainage volume refers to the total volume of water discharged during the drainage of the paddy field using the target drainage pipe. The stage drainage volume refers to the total volume of water discharged during the drainage of the updated drainage field using the updated drainage pipe. The drainage of the paddy field using the target drainage pipe means that the water in the paddy field flows out of the paddy field through the target drainage pipe under the action of gravity, and the drainage of the paddy field does not empty all the water in the paddy field, but only allows the water in the paddy field to flow out during the period from the opening to the closing of the drainage gate. The drainage flow rate refers to the flow rate of the water in the target drainage pipe during the drainage of the paddy field. The determination of the relay drainage pipe and the updated drainage field based on the target closing gate, the target drainage pipe and the paddy field means that when it is confirmed that the drainage gate in the target drainage pipe changes to the target closing gate, the target drainage pipe is used as the relay drainage pipe, and the paddy field drained using the target drainage pipe is used as the updated drainage field.

[0144] It should be understood that the method for calculating the stage drainage time based on the drainage pipe radius, the drainage flow rate, and the stage drainage volume is the same as the method for calculating the estimated drainage time based on the drainage pipe radius, the drainage flow rate, and the initial drainage volume, which will not be elaborated here. The method for determining the stage drainage pipe and the stage drainage field based on the stage closing gate, the updated drainage pipe, and the updated drainage field is the same as the method for determining the relay drainage pipe and the updated drainage field based on the target closing gate, the target drainage pipe, and the paddy field, which will not be elaborated here. The method for draining the updated drainage field using the updated drainage pipe is the same as the method for draining the paddy field using the target drainage pipe, which will not be elaborated here. The method for performing the safe closing operation on the target closing gate in the updated drainage pipe is the same as the method for performing the safe closing operation on the drainage gate in the target drainage pipe to obtain the target closing gate, which will not be elaborated here.

[0145] Exemplarily, if the time to confirm the optimal water level is 23:59 on May 10th, record the time in real-time starting from 23:59 on May 10th to obtain the regulation time. If the time to open the drainage gate in the drainage pipeline is 00:00 on May 11th, record the time in real-time starting from 00:00 on May 11th. When it is 00:02 on May 11th, the drainage time is 2 minutes. If the estimated drainage time is calculated to be 3 minutes, then at 00:03 on May 11th, perform a safety closing operation on the drainage gate in the target drainage pipeline. After the drainage gate is safely closed, obtain the target closing gate, and use the paddy field that has been drained as the updated drained field, and use the target drainage pipeline as the relay drainage pipeline. Since the stage time threshold is 2 hours, at 02:00 on May 11th, the drainage time is 2 hours, reaching the stage time threshold. Then open the target closing gate in the relay drainage pipeline. Since the target closing gate in the relay drainage pipeline is opened at 02:00 on May 11th, record the time in real-time starting from 02:00 on May 11th to obtain the updated drainage time. If the stage drainage time is 1 minute, then at 02:01 on May 11th, the updated drainage time is 1 minute, reaching the stage drainage time. Then perform a safety closing operation on the target closing gate in the updated drainage pipeline to obtain the stage closing gate, use the stage drained field as the updated drained field, use the updated drainage time as the drainage time, use the stage closing gate as the target closing gate, and use the stage drainage pipeline as the relay drainage pipeline. When another two hours pass, at 04:00 on May 11th, the drainage time reaches 2 hours again, then open the target closing gate in the relay drainage pipeline again, and at 06:00 on May 11th, open the target closing gate in the relay drainage pipeline again, and so on, until the regulation time reaches the single-day termination time, that is, when it reaches 23:59 on May 10th, use the stage drained field as the drained field to complete the process of intelligent drainage.

[0146] Specifically, the calculation formula for the estimated drainage time is as follows:

[0147]

[0148] Wherein, t ps is the estimated drainage time, V x is the initial drainage volume, r p is the radius of the drainage pipeline, s ps is the drainage flow rate, and π is the pi.

[0149] It should be explained that the estimated drainage time is the duration of the process of draining the updated drained field using the updated drainage pipeline.

[0150] Specifically, the step of performing a safety closing operation on the drainage gate in the target drainage pipeline to obtain the target closing gate includes:

[0151] Confirm the gate control mechanism of the drainage gate, wherein the gate control mechanism includes: a pushing motor, a pulling motor, a displacement sensor and a speed sensor;

[0152] Start the pushing motor, use the started pushing motor to close the drainage gate, and respectively use the speed sensor and the displacement sensor to monitor the closing speed and closing displacement in real time when the started pushing motor closes the drainage gate. If the closing speed is less than the preset jamming speed, then turn off the pushing motor and start the pulling motor;

[0153] Use the started pulling motor to open the drainage gate, record the time in real time starting from the time when the pulling motor is started to obtain the pulling time. When the pulling time is equal to the preset pulling time threshold, turn off the pulling motor, and return to the step of starting the pushing motor until the closing displacement reaches the preset closing threshold, then turn off the pushing motor to obtain the target closed gate.

[0154] It can be understood that the gate control mechanism is a device for controlling the opening and closing of the drainage gate. The pushing motor is an electric motor that can push the drainage gate to close. The pulling motor is an electric motor that can pull the drainage gate to open. The use of the started pushing motor to close the drainage gate means: using the started pushing motor to gradually close the drainage gate. The use of the started pulling motor to open the drainage gate means: using the started pulling motor to gradually open the drainage gate. The speed sensor is a sensor that can monitor the closing speed. The displacement sensor is a sensor that can monitor the closing displacement. The closing speed refers to the speed at which the drainage gate moves when the started pushing motor closes the drainage gate, and the closing displacement refers to the displacement of the drainage valve when the started pushing motor closes the drainage gate. And the technology of using the speed sensor and the displacement sensor to monitor the closing speed and closing displacement in real time when the started pushing motor closes the drainage gate is the prior art and will not be elaborated here.

[0155] It should be understood that since the water in the paddy field may be mixed with impurities such as soil, when the drainage valve is closed, it may be blocked by the soil. Therefore, in the embodiment of the present invention, by monitoring the closing speed, when the closing speed is lower than the jamming speed, it means that the drainage valve is stuck by a piece of soil during closing. Therefore, it is necessary to restart the pulling motor to appropriately open the drainage gate, so that the soil stuck in the drainage valve flows out with the water flow and then closes again, so as to complete the safe closing of the drainage gate. Optionally, the jamming speed is 0.001 m / s, the pulling time threshold is 3 s. The closing threshold is twice the radius of the drainage pipe.

[0156] S6. If the starting water level is less than or equal to the optimal water level, perform an intelligent water conveyance operation on the paddy fields in the target paddy field based on the regulation time, starting water level, optimal water level, paddy field monitoring agency, water storage reservoir, and water conveyance pipeline to obtain the water-conveyed fields.

[0157] Specifically, the intelligent water conveyance operation performed on the paddy fields in the target paddy field based on the regulation time, starting water level, optimal water level, paddy field monitoring agency, water storage reservoir, and water conveyance pipeline to obtain the water-conveyed fields includes:

[0158] Calculate the initial water conveyance volume according to the starting water level, optimal water level, and field area. The calculation formula is as follows:

[0159]

[0160] Where, V s is the initial water conveyance volume, S t is the starting water level, is the field area;

[0161] Use the light sensor, temperature sensor, and soil humidity sensor in the paddy field monitoring agency to obtain the field light intensity, field temperature, and field humidity of the paddy fields.

[0162] Calculate the estimated supplementary water level according to the field light intensity, field temperature, and field humidity. The calculation formula is as follows:

[0163]

[0164] Where, S y is the estimated supplementary water level, P t is the field light intensity, T t is the field temperature, τ t is the field humidity, α 0 is a preset reference coefficient, S 0 is the preset reference supplementary water level, and tanh is the hyperbolic tangent function;

[0165] Calculate the stage supplementary water volume according to the estimated supplementary water level and the field area. Among them, the stage supplementary water volume is the product of the estimated supplementary water level and the field area;

[0166] Obtain the radius of the water conveyance pipeline, open the water conveyance gate in the water conveyance pipeline to obtain the target water conveyance pipeline, use the water storage reservoir and the target water conveyance pipeline to convey water to the paddy field, and use the water flow velocity meter to obtain the water flow velocity when the target water conveyance pipeline conveys water to the paddy field. Starting from the time when the water conveyance gate in the water conveyance pipeline is opened and recording the time in real time, obtain the water conveyance time. Calculate the estimated water conveyance time based on the radius of the water conveyance pipeline, the water flow velocity, and the initial water volume. When the water conveyance time reaches the estimated water conveyance time, close the water conveyance gate in the target water conveyance pipeline to obtain the updated water conveyance field and the relay water conveyance pipeline;

[0167] Calculate the stage water conveyance time based on the radius of the water conveyance pipeline, the water flow velocity, and the stage water replenishment volume;

[0168] When it is confirmed that the water conveyance time reaches the stage time threshold, open the water conveyance gate in the relay water conveyance pipeline to obtain the updated water conveyance pipeline, use the water storage reservoir and the updated water conveyance pipeline to convey water to the updated water conveyance field. Starting from the time when the water conveyance gate in the relay water conveyance pipeline is opened and recording the time in real time, obtain the updated water conveyance time. When the updated water conveyance time reaches the stage water conveyance time, close the water conveyance gate in the updated water conveyance pipeline to obtain the stage water conveyance pipeline and the stage water conveyance field;

[0169] Take the stage water conveyance field as the updated water conveyance field, take the stage water conveyance pipeline as the relay water conveyance pipeline, take the updated water conveyance time as the water conveyance time, and return to the step when it is confirmed that the water conveyance time reaches the stage time threshold until the regulation time reaches the single-day termination time, and then take the stage water conveyance field as the water conveyance field.

[0170] Exemplarily, the staff of the farm calculate the average value of the height of the water level drop in multiple paddy fields in the history without rainfall and within the stage time threshold as the reference water replenishment level. The reference coefficient is a value set artificially by the staff of the farm.

[0171] It should be understood that since the light intensity and temperature of the field will affect the transpiration of rice in the paddy field, and the transpiration of rice will gradually consume the water in the paddy field, and the field humidity will affect the speed of water seepage downward in the soil of the paddy field, and the field temperature will also affect the evaporation speed of water in the paddy field, so the light intensity, temperature and humidity of the field will all affect the water level of the field. Therefore, it is necessary to convey water to the paddy field periodically. The estimated water replenishment level is the total height of the water level drop in the stage time threshold when the paddy field is affected by the transpiration of rice, the seepage of soil, and the evaporation of water.

[0172] It should be explained that the initial water conveyance volume refers to the total volume of water input during the process of conveying water to the paddy field using the target water conveyance pipeline. The relay water conveyance pipeline refers to the target water conveyance pipeline after the water conveyance valve is closed. The stage water conveyance pipeline refers to the updated water conveyance pipeline after the water conveyance valve is closed. The water conveyance pipeline radius refers to the radius of the water conveyance pipeline. The water conveyance flow rate refers to the flow rate of the water in the water conveyance pipeline when conveying water to the paddy field. The conveyance of water from the water storage reservoir to the paddy field using the water storage reservoir and the target water conveyance pipeline means that the water in the water storage reservoir is transported to the paddy field through the target water conveyance pipeline, and the conveyance of the water in the water storage reservoir to the paddy field does not mean that all the water in the water storage reservoir is transported to the paddy field, but only allows the water in the water storage reservoir to be transported during the period from the opening to the closing of the water conveyance gate. The updated water conveyance paddy field refers to the paddy field after water conveyance using the water storage reservoir and the target water conveyance pipeline. The stage water conveyance paddy field refers to the updated water conveyance paddy field after water conveyance using the water storage reservoir and the updated water conveyance pipeline.

[0173] It should be understood that the method of conveying water to the updated water conveyance paddy field using the water storage reservoir and the updated water conveyance pipeline is the same as the method of conveying water to the paddy field using the water storage reservoir and the target water conveyance pipeline, and will not be elaborated here. The method of calculating the estimated water conveyance time based on the water conveyance pipeline radius, water conveyance flow rate, and initial water conveyance volume and the method of calculating the stage water conveyance time based on the water conveyance pipeline radius, water conveyance flow rate, and stage makeup water volume are both the same as the method of calculating the estimated drainage time based on the drainage pipeline radius, drainage flow rate, and initial drainage volume, and will not be elaborated here.

[0174] Exemplarily, if the time when the optimal water level is confirmed is 23:59 on May 10th, then starting from 23:59 on May 10th and recording the time in real-time, the regulation time is obtained. If the time to open the water conveyance gate in the water conveyance pipeline is 00:00 on May 11th, then starting from 00:00 on May 11th and recording the time in real-time, the water conveyance time is obtained. If the estimated water conveyance time is calculated to be 3 minutes, then at 00:03 on May 11th, the water conveyance time is 3 minutes, reaching the estimated water conveyance time, and then the water conveyance gate in the target water conveyance pipeline is closed to obtain the updated water conveyance fields and the relay water conveyance pipeline. Since the stage time threshold is 2 hours, then at 02:00 on May 11th, the water conveyance time is 2 hours, reaching the stage time threshold, so the water conveyance gate in the relay water conveyance pipeline is opened. Since the water conveyance gate in the relay water conveyance pipeline is opened at 02:00 on May 11th, then starting from 02:00 on May 11th and recording the time in real-time again, the updated water conveyance time is obtained. If the stage water conveyance time is 1 minute, then at 02:01 on May 11th, the updated water conveyance time is 1 minute, reaching the stage water conveyance time, so the water conveyance gate in the updated water conveyance pipeline is closed to obtain the stage water conveyance pipeline and the stage water conveyance fields. The stage water conveyance fields are used as the updated water conveyance fields, the stage water conveyance pipeline is used as the relay water conveyance pipeline, and the updated water conveyance time is used as the water conveyance time. When another two hours pass, at 04:00 on May 11th, the water conveyance time reaches 2 hours again, then the water conveyance gate in the relay water conveyance pipeline is opened again, and at 06:00 on May 11th, the water conveyance gate in the relay water conveyance pipeline is opened again, and so on, until the regulation time reaches the single-day termination time, that is, when reaching 23:59 on May 10th, the stage water conveyance fields are used as the water conveyance fields, completing the process of intelligent water conveyance.

[0175] S7. Use the drained fields or the water conveyance fields as the paddy fields, and return to the step of obtaining the current date until a preset regulation end instruction is received, completing the stage water level regulation of the target paddy field.

[0176] It should be understood that since the single-day termination time is 24 hours, that is, from the time when the optimal water level is confirmed on the first day to the time when the drained fields or the water conveyance fields are obtained on the first day is 24 hours, exactly one day. So, using the drained fields or the water conveyance fields as the paddy fields and returning to the step of obtaining the current date, the date of the second day can be obtained again exactly on the second day, and subsequent water level regulation can be carried out, and so on, thus cycling once every day to automatically complete the water level regulation of the target paddy field.

[0177] Exemplarily, when the rice is ripe and the farm workers need to harvest the rice, a regulation end instruction can be initiated to terminate the water level regulation of the target paddy field.

[0178] To solve the problems described in the background art, the present invention receives a water level regulation instruction and confirms the target paddy field based on the water level regulation instruction. The target paddy field includes: paddy field land, a water storage reservoir, a water conveyance pipeline, and a drainage pipeline. The water conveyance pipeline includes: a water conveyance gate and a water flow rate regulator. The drainage pipeline includes: a drainage gate and a drainage flow rate regulator. The initial states of both the water conveyance gate and the drainage gate are closed states, and both the water conveyance gate and the drainage gate are treated with double-ring waterproofing. It can be seen that in the embodiment of the present invention, by confirming the target paddy field and defining the specific components of the target paddy field, the structural framework of the paddy field water level regulation system can be described more clearly, which helps to achieve efficient water resource management and precise water level adjustment. The double-ring waterproofing treatment can effectively prevent water leakage, improve the sealing and safety of the system, and then confirm the paddy field monitoring mechanism. The paddy field monitoring mechanism includes: a water level detector, a light sensor, a temperature sensor, and a soil humidity sensor. It can be seen that in the embodiment of the present invention, by constructing the paddy field monitoring mechanism, a basic device is provided for subsequent water level regulation of the paddy field land. Obtain the current date, use the water level detector to obtain the starting water level of the paddy field land, confirm the optimal water level based on the current date, record the time starting from the time when the optimal water level is confirmed in real time to obtain the regulation time. It can be seen that in the embodiment of the present invention, the growth trend and growth period of rice are estimated through the current date, so as to evaluate the optimal water level for rice growth at this stage according to the growth trend and growth period of rice. Compare the starting water level with the optimal water level. If the starting water level is greater than the optimal water level, calculate the stage adjustment water level and the initial adjustment water level according to the current date, the starting water level, the optimal water level, and the pre-constructed paddy field water level coefficient, and perform an intelligent drainage operation on the paddy field land in the target paddy field based on the regulation time, the stage adjustment water level, the initial adjustment water level, and the drainage pipeline to obtain the drained field. If the starting water level is less than or equal to the optimal water level, perform an intelligent water conveyance operation on the paddy field land in the target paddy field based on the regulation time, the starting water level, the optimal water level, the paddy field monitoring mechanism, the water storage reservoir, and the water conveyance pipeline to obtain the water-conveyed field. It can be seen that in the embodiment of the present invention, by performing an intelligent drainage operation on the paddy field land in the target paddy field and an intelligent water conveyance operation on the paddy field land in the target paddy field, the degree of automation of water level regulation of the paddy field land is improved. Take the drained field or the water-conveyed field as the paddy field land, and return to the step of obtaining the current date until a preset regulation end instruction is received, and complete the stage water level regulation of the target paddy field. It can be seen that in the embodiment of the present invention, by returning to the step of obtaining the current date, the water level regulation of the field is cyclically performed every day, and the degree of automation of water level regulation of the target paddy field is improved.
