In the figures:
The technical solutions of the embodiments of the present disclosure will be described below clearly and completely with reference to the drawings of the embodiments of the present disclosure, in order to enable those skilled in the art to better understand the solutions of the present disclosure. It is apparent that the embodiments to be described are some, but not all of the embodiments of the present disclosure. All the other embodiments obtained by those of ordinary skill in the art in light of the embodiments of the present disclosure without inventive efforts will fall within the scope of the present disclosure as claimed.
It should be noted that the terms such as “first” and “second” in the specification, the claims, and the above accompanying drawings of the present disclosure are intended to distinguish between similar objects but do not necessarily indicate a specific order or sequence. It should be understood that data used in this way are interchangeable in a proper circumstance, so that the embodiments of the present disclosure described herein can be implemented in other orders than those illustrated or described herein. In addition, the terms “including”, “comprising”, “having”, and any variants thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those steps or units expressly listed, but may include other steps or units not expressly listed or inherent to such a process, method, product, or device.
In step S102, a spray coefficient of an operating device at an operation location corresponding to a sampling point is acquired, where the spray coefficient is used for representing an amount of a chemical sprayed from the operating device at the operation location. Optionally, in this embodiment, the operating device may be a plant protection device (such as a drone or an unmanned aerial vehicle for plant protection) for spraying a chemical onto a target site. The operating device may communicate with a terminal device. The terminal may be a remote controller of the operating device (such as a remote controller of a drone), or the terminal may be a smart phone, a tablet computer, or other electronic device.
In this embodiment, the spray coefficient of the operating device at the operation location corresponding to the sampling point may be acquired by the terminal. The above-mentioned sampling point is a time period in which the spray coefficient is acquired during the operation of the operating device. The spray coefficient includes, but not limited to, the ratio of the spray flow rate to the moving speed of the operating device; where the spray flow rate is a flow rate of an agricultural chemical sprayed. A greater spray coefficient indicates a greater amount or volume of spray from the operating device at the operation location.
In step S104, color information corresponding to the operation location is acquired according to the spray coefficient.
Optionally, in this embodiment, the correspondence relationship between the spray coefficient and the color information may be stored in advance. Different spray coefficients may correspond to different colors, or may correspond to different shades of the same color and may be, for example, expressed by the brightness of a color.
In step S106, the operation location and the color information corresponding to the operation location are presented.
Optionally, in this embodiment, the color information corresponding to each operation location may be presented to the user via the terminal. The above-mentioned operation location is a location where the operating device performs the spraying operation. The color information is related to the spray coefficient. The spray coefficient is related to the spray amount (the amount of the chemical sprayed). The presentation of the operation location and the color information corresponding to the operation location is equivalent to the presentation of the operation location and information on the spray amount at the operation location.
The spray coefficient of the operating device at the operation location corresponding to the sampling point may be acquired by: acquiring information on a spray flow rate from the operating device at the operation location and information on a moving speed of the operating device when passing through the operation location; and determining a spray coefficient based on the information on the spray flow rate and the information on the moving speed of the operating device, wherein the spray coefficient is directly proportional to the spray amount at the operation location.
The color information corresponding to the operation location may be acquired by: determining a value interval (or range) within which the spray coefficient at the operation location falls; determining color information corresponding to the value interval, and using the color information corresponding to the value interval as color information corresponding to the operation location.
Optionally, in this embodiment, the correspondence relationship between the spray coefficient and the color information should be preset after a value interval within which the spray coefficient falls is determined and before color information corresponding to the value interval is determined. The spray coefficient may be set between 0 and 9. When the spray coefficient is 0, the corresponding color information is set to white. When the spray coefficient is 1 to 7, the corresponding color information is set to yellow. When the spray coefficient is 9, the corresponding color information is set to red.
The operation location and the color information corresponding to the operation location may be presented in the following ways.
In an example, the operation location may be a point in a moving trail. A moving trail of the operating device between adjacent operation locations may be filled with gradient colors according to the color information corresponding to the adjacent operation locations.
For example, in
In another example, the operation location may be a region in a moving trail. A moving trail of the operating device, operation locations in the moving trail, and color information corresponding to the operation locations may be presented in an electronic map. In this way, multiple operation regions can be connected so that the entire moving trail exhibits colors that can reflect the spray coefficients.
Further, if there is a gap between the regions corresponding to the operation locations, a moving trail between the adjacent operation locations may be filled with gradient colors according to the color information corresponding to the adjacent operation locations, and the moving trail which has been filled with the gradient colors is presented.
For example,
Optionally, steps of judging whether the spray coefficients corresponding to the adjacent operation locations fall within the same value interval, and determining to trigger the filling of the moving trail between the adjacent operation locations with gradient colors when the judgment result is NO may be further performed before filling the moving trail between the adjacent operation locations with gradient colors. When the judgment result is YES, it is determined to fill the moving trail between the adjacent operation locations with a specified color, where the specified color is a color corresponding to any one of the adjacent operation locations.
Optionally, the spray coefficient is set in a range of 0 to 9 and set within different value intervals. For example, the spray coefficients are divided into three intervals, namely, a first interval between 0 and 3, a second interval between 4 and 7, and a third interval between 8 and 9. Moreover, the first interval is set to correspond to a red color, the second interval is set to correspond to a green color, and the third interval is set to correspond to a blue color. Before filling a moving trail between adjacent operation locations with gradient colors, when it is judged that the spray coefficients corresponding to the adjacent operation locations do not fall within the same value interval, for example, when a first operation location and a second operation location adjacent to each other correspond to spray coefficients of 3 and 4, respectively, it is determined to trigger the filling of the moving trail between the adjacent operation locations with gradient colors between red and green. When both the first operation location and the second operation location adjacent to each other correspond to a spray coefficient of 4, it is determined to fill the moving trail between the adjacent operation locations with green.
The following step may be further performed after the operation location and the color information corresponding to the operation location are presented.
In step S1062, a control instruction is sent to the operating device, where the control instruction is used for controlling the operating device to perform at least one of the following operations:
In other words, in this embodiment, when the color information at the operation location is a first color, the operating device may be controlled to supplementarily spray the chemical at the operation location corresponding to the first color. Alternatively, when the color information at the operation location is a second color, the operating device is controlled to spray water for diluting at the operation location corresponding to the second color.
Optionally, a first spray coefficient corresponding to the first color described above is smaller than a second spray coefficient corresponding to the second color. Here, the first spray coefficient corresponds to an insufficient amount of the chemical sprayed, and the second spray coefficient corresponds to an excessive amount of the chemical sprayed.
Optionally, before sending a control instruction to the operating device, the method may further include the following steps:
Optionally, the control instruction is determined according to the comparison result so as to: supplementarily spray the chemical when the target spray amount is greater than the spray amount corresponding to the spray coefficient; and spray a dilution when the target spray amount is less than the spray amount corresponding to the spray coefficient.
In addition, the overall spraying status can be used for analyzing the total amount of a chemical sprayed onto the entire plot of land. If the entire plot of land is determined to be excessively sprayed according to the overall spray amount and the partial spray amount on a plant, the plant may be recorded as a non-green product with excessive agrochemicals.
In this embodiment, a spray coefficient of an operating device at an operation location corresponding to a sampling point is acquired, where the spray coefficient is used for representing an amount of a chemical sprayed from the operating device at the operation location; color information corresponding to the spray coefficient at the operation location is acquired; and the operation location and the color information corresponding to the operation location are presented. This allows the visualization of spraying of a chemical from the operating device during the operation, which enables the operator to intuitively determine the status of spray from the operating device during the operation. A place where is excessively sprayed, insufficiently sprayed, or not sprayed is intuitively visible by presenting the operation location and the color information corresponding to the operation location. In the case of excessive spraying, a dilution treatment can be performed in time to reduce agrochemical residues in a crop. In the case of missed spraying or insufficient spraying, the pilot can immediately re-plan a flight route for supplementary spray. This ensures the uniform spraying of agrochemicals on crops and the reasonable utilization of agrochemicals to increase the efficiency of spraying of agrochemicals and guarantee a good harvest for farmers, thereby solving the technical problem of low efficiency of spraying of the chemical caused by failing to determine a spray amount of the chemical applied to a specific position in a target area.
Optionally, in this embodiment, in the step S104, it is also possible to acquire a target spray amount corresponding to the operation location, and then calculate a difference degree value indicating the degree of a difference between the target spray amount and the spray coefficient at the operation location and acquire color information corresponding to the operation location according to the difference degree value. In this way, color information corresponding to an operation location is related to a difference degree value indicating the degree of a difference between the target spray amount and the spray coefficient corresponding to the operation location, so that it is convenient for the user to intuitively know whether the actual spray amount at the operation location reaches the desired spray amount. Optionally, the acquisition of a target spray amount corresponding to the operation location may include: acquiring a prescription map of a site to be sprayed, the prescription map being used for indicating a target amount of spray onto each point or each area in the site to be sprayed; and determining a target spray amount corresponding to the operation location according to the correspondence relationship between the operation location and a point or area on the prescription map.
In step S302, a spray coefficient of an operating device at an operation location corresponding to a sampling point is acquired, where the spray coefficient is used for representing an amount of a chemical sprayed from the operating device at the operation location.
In an optional embodiment, the above-mentioned sampling point is a time period in which the spray coefficient is acquired during the operation of the operating device. The spray coefficient is the ratio of the spray flow rate to the moving speed of the operating device; where the spray flow rate is a flow rate of an agricultural chemical sprayed. A greater spray coefficient indicates a greater amount of spray from the operating device at the operation location.
In step S304, an element corresponding to the operation location is acquired according to the spray coefficient, where the element is an element in a presentation interface.
Optionally, the above-mentioned element may include at least one of the following information: graphic information, color information, and graphic density information.
Optionally, the above-mentioned element is color information. The correspondence relationship between the spray coefficient and the color information may be stored in advance. Different spray coefficients may correspond to different colors, or may correspond to different shades of the same color and may be, for example, expressed by the brightness of a color.
Optionally, the above-mentioned element is also information representing the degree of a difference between the target spray amount and the spray coefficient at the operation location.
In step S306, information on a change trend between adjacent elements is determined.
Optionally, in this embodiment, the information on a change trend between adjacent elements may be information on a color change trend, a graphic change trend, or a change in graphic density.
In step S308, the operation location, the element corresponding to the operation location, and the change trend information are presented.
Optionally, when the element is color information, the above-mentioned operation location is a location where the operating device performs an operation. The color information is related to the spray coefficient. The spray coefficient is related to the spray amount. The presentation of the operation location, the color information corresponding to the operation location, and the trend of change in the color information is equivalent to the presentation of the operation location and information on the spray amount at the operation location.
The spray coefficient of the operating device at the operation location corresponding to the sampling point may be acquired by: acquiring information on a spray flow rate from the operating device at the operation location and information on a moving speed of the operating device when passing through the operation location; and determining a spray coefficient based on the information on the spray flow rate and the information on the moving speed of the operating device, wherein the spray coefficient is directly proportional to the spray amount at the operation location.
The color information corresponding to the spray coefficient at the operation location may be acquired by: determining a value interval within which the spray coefficient falls; determining color information corresponding to the value interval, and using the color information corresponding to the value interval as color information corresponding to the spray coefficient.
Optionally, the correspondence relationship between the spray coefficient and the color information should be preset after a value interval within which the spray coefficient falls is determined and before color information corresponding to the value interval is determined. The spray coefficient may be set between 0 and 9. When the spray coefficient is 0, the corresponding color information is set to white. When the spray coefficient is 1 to 7, the corresponding color information is set to yellow. When the spray coefficient is 9, the corresponding color information is set to red.
The operation location and the color information corresponding to the operation location may be presented by: presenting, in an electronic map, a moving trail of the operation device, operation locations in the moving trail, and the color information corresponding to the operation locations; filling the moving trail between adjacent operation locations with gradient colors and presenting the moving trail which has been filled with the gradient colors. In other words, in this embodiment, a moving trail of the operating device between adjacent operation locations may be filled with gradient colors according to the color information corresponding to the adjacent operation locations.
Optionally, steps of judging whether the spray coefficients corresponding to the adjacent operation locations fall within the same value interval, and determining to trigger the filling of the moving trail between the adjacent operation locations with gradient colors when the judgment result is NO may be further performed before filling the moving trail between the adjacent operation locations with gradient colors. When the judgment result is YES, it is determined to fill the moving trail between the adjacent operation locations with a specified color, where the specified color is a color corresponding to any one of the adjacent operation locations.
Optionally, the spray coefficient is set in a range of 0 to 9 and set within different value intervals. For example, the spray coefficients are divided into three intervals, namely, a first interval between 0 and 3, a second interval between 4 and 7, and a third interval between 8 and 9. Moreover, the first interval is set to correspond to a red color, the second interval is set to correspond to a green color, and the third interval is set to correspond to a blue color. Before filling a moving trail between adjacent operation locations with gradient colors, when it is judged that the spray coefficients corresponding to the adjacent operation locations do not fall within the same value interval, for example, when a first operation location and a second operation location adjacent to each other correspond to spray coefficients of 3 and 4, respectively, it is determined to trigger the filling of the moving trail between the adjacent operation locations with gradient colors between red and green. When both the first operation location and the second operation location adjacent to each other correspond to a spray coefficient of 4, it is determined to fill the moving trail between the adjacent operation locations with green.

In other words, when the color information at the operation location is a first color, the operating device may be controlled to supplementarily spray the chemical at the operation location corresponding to the first color. When the color information at the operation location is a second color, the operating device is controlled to spray water for diluting at the operation location corresponding to the second color.
Optionally, a first spray coefficient corresponding to the first color described above is smaller than a second spray coefficient corresponding to the second color.

Optionally, the control instruction is determined according to the comparison result so as to: supplementarily spray the chemical when the target spray amount is greater than the spray amount corresponding to the chemical spraying operation coefficient; and spray a dilution when the target spray amount is less than the spray amount corresponding to the chemical spraying operation coefficient.
In this embodiment, an operation coefficient of an operating device at an operation location corresponding to a sampling point is acquired, where the operation coefficient is used for representing an amount of operation performed by the operating device at the operation location; marking information corresponding to the operation coefficient at the operation location is acquired; and the operation location and the marking information corresponding to the operation location are presented. This enables a control device to receive specified chemical information collected by a server and determine operation parameters for the operating device according to the chemical information, so that the control device can control loading of the operating device with a chemical and an operation of the operating device. In this way, less time and manual effort are consumed during use of a drone, and the working efficiency of the drone is increased, thereby solving the technical problem of low efficiency of spraying of the chemical caused by failing to determine a spray amount of the chemical applied to a specific position in a target area.

In this embodiment, a spray coefficient of an operating device at an operation location corresponding to a sampling point is acquired, where the spray coefficient is used for representing an amount of a chemical sprayed from the operating device at the operation location; color information corresponding to the spray coefficient at the operation location is acquired; and the operation location and the color information corresponding to the operation location are presented. This allows the visualization of spraying of a chemical from the operating device during the operation, which enables the operator to intuitively determine the status of spray from the operating device during the operation. A place where is excessively sprayed, insufficiently sprayed, or not sprayed is intuitively visible by presenting the operation location and the color information corresponding to the operation location. In the case of excessive spraying, a dilution treatment can be performed in time to reduce agrochemical residues in a crop. In the case of missed spraying or insufficient spraying, the pilot can immediately re-plan a flight route for supplementary spray. This ensures the uniform spraying of agrochemicals on crops and the reasonable utilization of agrochemicals to increase the efficiency of spraying of agrochemicals and guarantee a good harvest for farmers, thereby solving the technical problem of low efficiency of spraying of the chemical caused by failing to determine a spray amount of the chemical applied to a specific position in a target area.
