Description

Technical Field

[0002] With the development of modern agricultural technology, precision agricultural management has gradually become a core direction for improving production efficiency and reducing resource waste. In the field of agricultural plant protection, monitoring operations are an important means to reduce labor and regulate crop growth. However, traditional agricultural monitoring systems generally have the following problems:

[0062] The present invention provides Figures 1-14 An agricultural monitoring system and method involving terminal positioning is shown. The agricultural monitoring system provided by the present invention can not only quickly find the sprayable area, but also adjust and control the execution module of the corresponding area to perform fixed-point area spraying, thereby improving agricultural spraying efficiency and reducing costs.

[0063] refer to Figure 1 As shown in , the system includes a monitoring device, a data processing module and an execution module. In agricultural planting, the planting area is divided into multiple sub-intervals. The monitoring device is used to capture crop growth images in each sub-interval and send the growth images to the data processing module. The data processing module receives and analyzes the crop growth images and determines the sprayable areas of the sub-intervals. The monitoring device also has a positioning function, which locates the sprayable areas and sends the positioning data to the execution module. The execution module sprays the fixed area after receiving the positioning data.

[0064] Among them, the monitoring device includes a locator, a camera, a temperature sensor, a humidity sensor and a wind speed sensor.

[0065] The locator is a GPS locator, which is used to locate the monitoring device; the camera is used to capture images of crop growth conditions; the temperature sensor is used to monitor the air temperature near the monitoring device; the humidity sensor is used to monitor the air humidity near the monitoring device; and the wind speed sensor is used to monitor the air flow rate near the monitoring device.

[0066] The storage unit of the data processing module stores crop images and soil images. By comparing the crop growth status image or soil image taken by the camera with the original image data in the storage unit, it can be determined whether the crops need to be sprayed.

[0067] The execution module includes a spray module, which is used to spray crops near the monitoring device. The spray module and the monitoring device are both integrated on the terminal-positioned agricultural monitoring equipment.

[0068] refer to Figure 2 As shown in the figure, the terminal-positioned agricultural monitoring equipment includes a base 1, a heating box 2 and a sprayer 3 arranged in sequence from bottom to top. A monitoring box 5 is arranged above the sprayer 3. The locator, temperature sensor, humidity sensor and wind speed sensor are all integrated in the monitoring box 5, and the camera 6 is installed on the upper surface of the monitoring box 5.

[0069] refer to Figure 3 As shown in the figure, the spray module includes a filter box 8, a high-pressure delivery pump 7, a main water pipe 9, an auxiliary water pipe 10 and a spray hole 4. The sprayer 3 is a cylindrical structure. The filter box 8 is installed inside the lower end of the sprayer 3. The high-pressure delivery pump 7 is connected and arranged above the filter box 8. The top of the high-pressure delivery pump 7 is connected to the main water pipe 9. The main water pipe 9 is distributed along the height direction of the sprayer 3. The spray hole 4 runs through the outer surface of the sprayer 3, and there are multiple spray holes 4. The multiple spray holes 4 are distributed on the outer surface of the sprayer 3 along a spiral trajectory. The main water pipe 9 is connected to the auxiliary water pipe 10. There are multiple auxiliary water pipes 10. The auxiliary water pipe 10 is connected to the corresponding spray hole 4 at one end away from the main water pipe 9.

[0070] During operation, the high-pressure delivery pump 7 starts to generate suction, and the water enters the main water pipe 9 after being filtered by the filter box 8, is evenly distributed in the auxiliary water pipe 10 through the main water pipe 9, and then is sprayed out from the spray hole 4 to form a spray.

[0071] refer to Figure 14 As shown in , there are multiple groups of terminal-positioned agricultural monitoring equipment arranged at equal distances, so as to spray all crops in the planting area.

[0072] refer to Figure 4As shown in the figure, a first solenoid valve 19 is provided in the spray hole 4, which can open the corresponding spray hole 4, thereby controlling the spray to be sprayed from a specified position and spraying the crops in a targeted manner. An annular groove 17 is provided in the middle section of the spray hole 4. Water is released after passing through the annular groove 17 to form a spray. A conical channel 18 is provided at one end of the spray hole 4 that passes through the sprayer 3. The conical channel 18 is a conical groove structure. The diameter of the end of the conical channel 18 away from the annular groove 17 is small, and the diameter of the end of the conical channel 18 away from the annular groove 17 gradually decreases from bottom to top along the height direction of the spray hole 4 of the sprayer 3. When water is discharged through the conical channel 18, the smaller the end of the conical channel 18 away from the annular groove 17 is, the longer the water spray distance is, forming a spray effect that is both far and near. The spray is more uniform, replacing the spray method in the prior art. There will be no phenomenon that the farther the spray amount is, the larger the spray amount is, and the closer the spray amount is, the smaller the spray amount is, so that the spray amount in the entire spray range is uniform.

[0073] refer to Figure 5 As shown in the figure, a cache chamber 24 is provided inside the base 1, and a threaded interface 21 is provided at the lower end of the base 1. The threaded interface 21 is connected to the water pipe arranged underground. The diameter of the cache chamber 24 is larger than the diameter of the threaded interface 21. The upper end of the cache chamber 24 is connected to a heat-insulating pipe 27. The heat-insulating pipe 27 is vertically arranged inside the heating box 2. The upper end of the heat-insulating pipe 27 is connected to the lower end of the filter box 8. A heat exchange pipe 26 is also provided in the heating box 2. The heat exchange pipe 26 is bent back and forth, and the upper end of the heat exchange pipe 26 is connected to the filter box 8. The lower end of the heat exchange pipe 26 is connected to the side of the lower end of the insulation pipe 27. The heat exchange pipe 26 and the insulation pipe 27 are respectively provided with a third solenoid valve 29 and a second solenoid valve 28. An electric heating plate 25 is also provided on the inner wall of the heating box 2. Water is stored in the heating box 2. A movable sealing plate 22 is provided in the cache chamber 24. A second spring 23 is fixedly connected between the upper end of the movable sealing plate 22 and the upper inner wall of the cache chamber 24. The diameter of the movable sealing plate 22 is smaller than the diameter of the cache chamber 24 and larger than the diameter of the threaded interface 21.

[0074] When the water pipe arranged underground is connected to the threaded interface 21, the upper end of the water pipe rises against the movable sealing plate 22, so that the buffer chamber 24 is opened, and water can pass through the threaded interface 21, the buffer chamber 24, and the insulated pipe 27 in turn into the filter box 8 for filtration.

[0075] It should be noted that the upper end of the water pipe arranged underground is an inclined pipe, which ensures that water can smoothly enter the cache chamber 24. This is a common existing technology and will not be elaborated here.

[0076] The insulated pipe 27 is made of an insulating material such as a polyurethane foam layer, a glass fiber layer, a rock wool layer, etc., which has a good thermal insulation effect. The heat exchange pipe 26 can be made of copper pipes, stainless steel pipes, aluminum pipes, etc., which has a good thermal conductivity. When the electric heating plate 25 is started, it can heat the water stored in the heating box 2. When the temperature sensor in the monitoring device detects that the nearby temperature is too low, the third solenoid valve 29 can also be opened to control the water in the heat exchange pipe 26 to be sprayed after heat exchange through the heating box 2, which has a certain heating effect and can promote the growth of crops to a certain extent. An internal temperature sensor 20 is provided in the auxiliary water pipe 10. The internal temperature sensor 20 can monitor the temperature of the water sprayed from the spray hole 4. When the water temperature exceeds the set threshold, the electric heating plate 25 stops heating to avoid the phenomenon of spray scalding crops due to excessive heating. When the spray does not need to be heated, the second solenoid valve 28 can be opened to allow the water to directly pass through the insulated pipe 27 into the filter box 8 for filtration and then be discharged from the spray hole 4.

[0077] refer to Figure 5 and Figure 6 As shown in the figure, in order to prevent the spray module from being blocked by impurities in the water, a maintenance-free activated carbon filter plate 31 is provided in the filter box 8. The activated carbon filter plates 31 are provided in multiple pieces, and the multiple activated carbon filter plates 31 are distributed at equal distances on the left and right. The upper ends of the multiple activated carbon filter plates 31 are commonly fixed with a base plate 33, and the lower ends of the multiple activated carbon filter plates 31 are commonly fixed with a positioning plate 30. The positioning plate 30 is fixedly connected to the inner wall of the filter box 8, and a filter gap 34 is formed between adjacent activated carbon filter plates 31. The lower end of the filter gap 34 is open and corresponds to the position where the lower end of the filter box 8 is connected to the insulation pipe 27 and the heat exchange pipe 26.

[0078] A collecting box 35 is fixedly provided at the upper end of the base plate 33, and a sewage outlet 43 connecting the filtering gap 34 and the interior of the collecting box 35 is provided on the base plate 33. A baffle 42 is movably fitted at the opening of one end of the sewage outlet 43 connecting to the interior of the collecting box 35. One end of the baffle 42 is hinged in the collecting box 35 through a hinge shaft 44, and a third spring 41 is fixedly provided on the upper surface of the other end of the baffle 42. The upper end of the third spring 41 is fixedly connected to the upper inner wall of the collecting box 35. Multiple activated carbon filter plates 31 together constitute a filter element assembly, and a side channel 32 is formed between the periphery of the filter element assembly and the inner wall of the filter box 8. A discharge chamber 36 is formed between the side of the collecting box 35 away from the filter element assembly and the inner wall of the filter box 8. The discharge chamber 36 and the side channel 32 are connected to each other, and the upper end of the discharge chamber 36 is connected to the high-pressure delivery pump 7.

[0079] During operation, no matter the water discharged into the filter box 8 from the heat exchange pipe 26 or the insulation pipe 27, it first enters the multiple filter gaps 34. The water hits the bottom surface of the base plate 33 upwards and then flows back to hit the side of the activated carbon filter plate 31, reducing the impact force. The water is filtered out from the side of the activated carbon filter plate 31 into the side channel 32 and then enters the high-pressure delivery pump 7 from the discharge chamber 36. The filtration area is increased in the filter element assembly of the same volume, sharing the impurities in the filtration, and avoiding the problem of impurities clogging the activated carbon filter plate 31 and reducing the filtration effect.

[0080] When water impacts the bottom surface of the substrate 33, it will also impact the baffle 42. Since the upper end of the baffle 42 is connected to the third spring 41, under the action of water impact, the baffle 42 will rotate clockwise around the hinge shaft 44 as the axis, and then rotate counterclockwise due to the elastic reset action of the third spring 41, forming an opening and closing process. In this process, impurities in the water can be effectively collected in the collection box 35, reducing the impurities remaining in the filter gap 34. When the water impacts upward, it will also drive the impurities attached to the side of the activated carbon filter plate 31 into the interior of the collection box 35 from the sewage outlet 43, further reducing the problem of impurity residues in the filter gap 34.

[0081] A working chamber 37 is also provided inside the sprayer 3, and a sewage pump 38 is provided in the working chamber 37. The output end of the sewage pump 38 is connected to the interior of the sprayer 3, and the input end of the sewage pump 38 is connected to a sewage pipe 39. The sewage pipe 39 is connected to the interior of the collecting box 35. A fourth solenoid valve 40 is provided in the sewage pipe 39. When the fourth solenoid valve 40 and the sewage pump 38 are opened, the impurities collected in the collecting box 35 can be pumped out to the outside of the sprayer 3, thereby achieving the purpose of eliminating manual maintenance and reducing the replacement frequency of the activated carbon filter plate 31. The sprayer is particularly suitable for use in the agricultural field.

[0082] refer to Figure 7 As shown in the figure, an arc-shaped cleaning rod assembly 45 is provided above the monitoring box 5. The arc-shaped cleaning rod assembly 45 has a semi-annular structure. The arc-shaped cleaning rod assembly 45 is fitted at the outer circle of the lower end of the camera 6. The part of the camera 6 protruding from the monitoring box 5 is a hemispherical structure. The arc-shaped cleaning rod assembly 45 can rotate along the outer surface of the camera 6, thereby scraping off the dust on the outer surface of the camera 6, ensuring that the camera 6 can be used normally for photographing crops outdoors or in a greenhouse.

[0083] refer to Figures 9 and 10 as well as Figure 12As shown in the figure, the arc-shaped cleaning rod assembly 45 includes a cleaning rod housing 46 and a cleaning cotton layer 49.

When a flying bird stays on the monitoring box 5 or the camera 6, due to gravity, the first rotating seat 16 will rotate relative to the supporting vertical plate 13. Due to the elastic force of the first spring 15, the monitoring box 5 and the camera 6 remain in an unstable state, avoiding the birds from staying, especially preventing the birds from building nests.

[0088] A card block 62 is fixedly provided on one side of the first rotating seat 16 close to the supporting vertical plate 13, and a card slot 63 is provided on one side of the supporting vertical plate 13 close to the first rotating seat 16.

A protruding plate 58 is fixedly provided on the lower surface of the monitoring box 5. A second electromagnetic block 59 and a first electromagnetic block 57 are fixedly provided on the side of the protruding plate 58 close to the first rotating seat 16. When the wind speed sensor in the monitoring device detects that the wind speed is too high, In order to affect the camera's shooting, power is applied to the protruding plate 58 and the first electromagnetic block 57, and the protruding plate 58 and the first electromagnetic block 57 generate a repulsive magnetic force. At this time, the first rotating seat 16 will move to a position that fits the supporting vertical plate 13, and the card block 62 is engaged in the corresponding card slot 63, thereby realizing the positioning of the monitoring box 5, so that the camera 6 is no longer disturbed by the wind and swings violently. When there is no wind or a light breeze and it does not affect the camera 6 shooting, the first rotating seat 16 can be reset to switch to the working mode of preventing birds from staying.

[0089] It should also be noted that the height of the monitoring box 5 and the camera 6 can also be controlled by the electric push rod 12, so as to adjust the height of the monitoring box 5 and the camera 6 according to the area of the planting area and the number of agricultural monitoring equipment positioned at the terminal.
