[0014] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0015] A method and device for handling abnormalities in farmland water-fertilizer rotation irrigation according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0016] Figure 1 It is a flow chart of a method for handling abnormalities in farmland water-fertilizer rotation irrigation provided in an embodiment of the present application. Figure 1 The method for handling abnormalities in the rotation of water and fertilizer in farmland can be executed by a computer or a server, or by software on the computer or the server. Figure 1 As shown, the method for handling abnormality of farmland water-fertilizer rotation irrigation includes:

[0017] S101, obtaining land information of each area in the farmland, dividing each area into a plurality of rotation irrigation groups according to the land information of each area, generating a rotation irrigation order for each rotation irrigation group, and irrigating each rotation irrigation group in sequence according to the rotation irrigation order, wherein each rotation irrigation group includes one or more areas;

[0018] S102, in the process of irrigating each rotation irrigation group in sequence, obtaining the rotation irrigation data of the current rotation irrigation group in real time;

[0019] S103, diagnosing whether there is irrigation abnormality in the current irrigation group based on the irrigation data;

[0020] S104, determining a solution for the abnormal rotation irrigation from an abnormality processing database, and resolving the abnormal rotation irrigation according to the solution.

[0021] In the process of irrigating each irrigation group, the irrigation data of the current irrigation group is obtained in real time, and then the current irrigation group is diagnosed to have irrigation anomalies. The abnormality handling database stores various treatment plans for irrigation anomalies. When the current irrigation group is diagnosed to have irrigation anomalies, the treatment plan for irrigation anomalies is determined from the abnormality handling database, and the irrigation anomalies are resolved according to the treatment plan. When the current irrigation group is diagnosed to have no irrigation anomalies, it is determined that the irrigation of the current irrigation group is normal. After the irrigation of the current irrigation group is terminated, the next irrigation group is diagnosed to have irrigation anomalies.

[0022] According to the technical solution provided by the embodiment of the present application, the land information of each area in the farmland is obtained, each area is divided into multiple rotation irrigation groups according to the land information of each area, and the rotation irrigation order of each rotation irrigation group is generated, and each rotation irrigation group is irrigated in turn according to the rotation irrigation order, wherein each rotation irrigation group contains one or more areas; in the process of irrigating each rotation irrigation group in turn, the rotation irrigation data of the current rotation irrigation group is obtained in real time; based on the rotation irrigation data, it is diagnosed whether there is an abnormal rotation irrigation in the current rotation irrigation group; the processing scheme of the abnormal rotation irrigation is determined from the abnormality processing database, and the abnormal rotation irrigation is solved according to the processing scheme. The above-mentioned technical means can solve the problem that the prior art cannot solve the faults occurring in the process of farmland irrigation and fertilization in a timely manner, thereby improving the efficiency of water and fertilizer irrigation.

[0023] Furthermore, each area is divided into a plurality of rotation irrigation groups according to the land information of each area, including: the land information includes location information and soil information; based on the soil information of each area, the required amount of water and fertilizer for each area is calculated; each area is divided into a plurality of rotation irrigation groups according to the location information of each area and the required amount of water and fertilizer.

[0024] The location information of an area is the location of the area, and the soil data of an area includes humidity, temperature, pH value, EC value (Electrical Conductivity), etc. Different degrees of soil information correspond to different water and fertilizer amounts (which can be obtained by statistical historical irrigation information, and artificial irrigation selects water and fertilizer amounts under different degrees of soil information). The water and fertilizer amounts refer to the water and fertilizer amounts per mu.

[0025] Furthermore, each area is divided into multiple rotation irrigation groups according to the location information of each area and the required amount of water and fertilizer, including: according to the location information of each area, the areas within a preset distance are preliminarily divided together as a rotation irrigation group, wherein the multiple rotation irrigation groups obtained by the preliminary division contain repeated areas; according to the principle that the required amount of water and fertilizer for each area in the same rotation irrigation group is similar, the repeated areas in the multiple rotation irrigation groups obtained by the preliminary division are adjusted so that the adjusted multiple rotation irrigation groups do not contain repeated areas.

[0026] For example, according to the location information of each area, areas 1, 2, and 3 are divided into the first irrigation group, and areas 3, 4, and 7 are divided into the second irrigation group. Area 3 is repeated in the first and second irrigation groups, because each area only needs to be irrigated once, so areas in different irrigation groups should not be repeated. When adjusting the areas in the irrigation group, the amount of water and fertilizer required for area 3 is close to that required for areas 1 and 2, so it is finally determined that area 3 belongs to the first irrigation group.

[0027] If the difference between the amount of water and fertilizer required in area 3 and that required in areas 1 and 2 is less than the preset difference, it can be determined that the amount of water and fertilizer required in area 3 is close to that required in areas 1 and 2. Or if the difference between the amount of water and fertilizer required in area 3 and that required in areas 1 and 2 is less than the difference between the amount of water and fertilizer required in area 3 and that required in areas 4 and 7, it can be determined that the amount of water and fertilizer required in area 3 is close to that required in areas 1 and 2.

[0028] Furthermore, the irrigation order of each irrigation group is generated, including: determining the position of each irrigation group based on the position information of the area included in each irrigation group; taking each irrigation group as a node, based on the position of each node, using the optimal path algorithm to generate the shortest path traversing each node, and taking the traversal order of each node in the shortest path as the irrigation order.

[0029] The center point of the position of each area in the rotation irrigation group can be used as the position of the rotation irrigation group. Each rotation irrigation group is regarded as a node. Based on the position of each rotation irrigation group, the optimal path algorithm is used to generate the optimal order of irrigating each rotation irrigation group, so that the loss of irrigating each rotation irrigation group is minimized. This is equivalent to the shortest path traversing each rotation irrigation group. The optimal path algorithm is an existing algorithm and will not be described here. Finally, each rotation irrigation group is irrigated in turn according to the optimal order.

[0030] Furthermore, based on the rotation irrigation data, it is diagnosed whether the current rotation irrigation group has rotation irrigation abnormality, including: the rotation irrigation data includes the water and fertilizer machine status, the solenoid valve status, the regional water and fertilizer flow, the fertilizer suction pump status, the fertilizer flow, the irrigation pump status and the water flow; when the water and fertilizer machine status is offline, it is diagnosed that the current rotation irrigation group has the water and fertilizer machine offline abnormality; when the solenoid valve status is offline, it is diagnosed that the current rotation irrigation group has the solenoid valve offline abnormality; when the regional water and fertilizer flow is less than the preset water and fertilizer flow, it is diagnosed that the current rotation irrigation group has a single irrigation failure; when the fertilizer suction pump status is on but the fertilizer flow is less than the preset fertilizer flow, it is diagnosed that the current rotation irrigation group has the fertilizer suction pump abnormality; when the irrigation pump status is on but the water flow is less than the preset water flow, it is diagnosed that the current rotation irrigation group has the irrigation pump abnormality; rotation irrigation abnormalities include water and fertilizer machine offline abnormality, solenoid valve offline abnormality, single irrigation failure, fertilizer suction pump abnormality, and irrigation pump abnormality.

[0031] The irrigation pump is responsible for controlling the pumping of water, and the fertilizer suction pump is responsible for sucking fertilizer. The fertilizer suction pump is a component of the water and fertilizer machine. The water and fertilizer machine is responsible for the entire process of sucking and injecting fertilizer. The solenoid valve is equivalent to a faucet and is responsible for switching. Normal irrigation requires the water and fertilizer machine to be online, the solenoid valve to be online, the fertilizer suction pump to be started, and the irrigation pump to be started. In addition, the fertilizer flow rate should be greater than or equal to the preset fertilizer flow rate to consider that the fertilizer suction pump is working normally. The fertilizer flow rate is the size of the fertilizer flow rate extracted by the fertilizer suction pump. The water flow rate should be greater than or equal to the preset water flow rate to consider that the irrigation pump is working normally. The water flow rate is the size of the water flow rate extracted by the irrigation pump. The regional water and fertilizer flow rate is the size of the water and fertilizer flow rate in the detection area. When the irrigation of an area is normal, its regional water and fertilizer flow rate must be in a reasonable range. When the water and fertilizer machine status is offline, it is determined that there is an abnormality in the water and fertilizer machine offline. When the solenoid valve status is offline, it is determined that there is an abnormality in the solenoid valve offline. When the regional water and fertilizer flow rate is less than the preset water and fertilizer flow rate, it is determined that there is a single irrigation failure. When the fertilizer suction pump status is on but the fertilizer flow rate is less than the preset fertilizer flow rate, it is determined that there is an abnormality in the fertilizer suction pump. When the irrigation pump state is on but the water flow rate is less than the preset water flow rate, it is determined that there is an irrigation pump abnormality.

[0032] Furthermore, the rotation irrigation abnormality is solved according to the processing plan, including: when the rotation irrigation abnormality is the water and fertilizer machine offline abnormality, the rotation irrigation abnormality is solved according to the first processing plan; when the rotation irrigation abnormality is the solenoid valve offline abnormality, the rotation irrigation abnormality is solved according to the second processing plan; when the rotation irrigation abnormality is a single irrigation failure, the rotation irrigation abnormality is solved according to the third processing plan; when the rotation irrigation abnormality is the fertilizer suction pump abnormality, the rotation irrigation abnormality is solved according to the fourth processing plan; when the rotation irrigation abnormality is the irrigation pump abnormality, the rotation irrigation abnormality is solved according to the fifth processing plan.

[0033] The first processing plan: determine the number of offline water and fertilizer machines. When it is less than the first number, continue irrigation. When it is greater than or equal to the first number, stop irrigation and control the water and fertilizer machines to go online. Continue irrigation after the offline number is less than the first number.

[0034] The second processing plan: determine the number of offline solenoid valves, and when it is less than the second number, continue irrigation; when it is greater than or equal to the second number, stop irrigation, control the solenoid valves to go online, and continue irrigation after the offline number is less than the second number.

[0035] The third treatment plan: record the number of failures in the current irrigation area in the current rotation irrigation group, re-irrigate, and when the number of failures is greater than the preset number, end the irrigation and add the area to the next rotation irrigation group.

[0036] The abnormality of the fertilizer suction pump is usually caused by the lack of fertilizer, so the fourth solution is: add fertilizer and restart the fertilizer suction pump.

[0037] Irrigation pump abnormality is generally caused by a fault in the irrigation pump, so the fifth solution is to restart the irrigation pump.

[0038] Figure 2 FIG. 1 is a flow chart of another method for handling abnormalities in farmland water and fertilizer rotation irrigation provided by an embodiment of the present application. Figure 2 As shown, the method includes:

[0039] Execute the following loop:

[0040] S201, determining whether i is greater than N, wherein i is the serial number of the rotation irrigation group, the initial value of i is 1, and N is the number of the rotation irrigation groups;

[0041] S202, when i is greater than N, it is determined that all rotation irrigation groups have been irrigated and the cycle ends;

[0042] S203, when i is less than or equal to N, obtaining the irrigation data of the i-th irrigation group in real time;

[0043] S204, diagnosing whether there is irrigation abnormality in the i-th irrigation group based on the i-th irrigation data;

[0044] S205, if it does not exist, when the irrigation of the i-th irrigation group is finished, update i with the value i plus 1;

[0045] S206: If it exists, determine the treatment plan for the rotation irrigation exception from the exception handling database, solve the rotation irrigation exception according to the treatment plan, and update i with the value of i plus 1 when irrigating the i-th rotation irrigation group.

[0053] In the process of irrigating each irrigation group, the irrigation data of the current irrigation group is obtained in real time, and then the current irrigation group is diagnosed to have irrigation anomalies.

[0058] For example, according to the location information of each area, areas 1, 2, and 3 are divided into the first irrigation group, and areas 3, 4, and 7 are divided into the second irrigation group. Area 3 is repeated in the first and second irrigation groups, because each area only needs to be irrigated once, so areas in different irrigation groups should not be repeated. When adjusting the areas in the irrigation group, the amount of water and fertilizer required for area 3 is close to that required for areas 1 and 2, so it is finally determined that area 3 belongs to the first irrigation group.

[0060] In some embodiments, the division module 301 is further configured to determine the location of each irrigation group based on the location information of the area included in each irrigation group; take each irrigation group as a node, and based on the location of each node, use the optimal path algorithm to generate the shortest path traversing each node, and use the traversal order of each node in the shortest path as the irrigation order.
