[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0060] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0061] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0062] In the description of the present application, the terms “first”, “second”, “third”, etc. are only used to distinguish the descriptions and should not be understood as indicating or implying relative importance.

[0063] In the description of this application, "connection" and / or "connected" should be understood as "electrical connection", "communication connection", etc. if the connected and / or "connected" circuits, modules, units, etc. have electrical signals or data transmission with each other.

[0064] With the rapid development of drone technology, drones are widely used in more and more fields. In the field of vegetation protection, plant protection drones can be used in agricultural scenarios such as vegetation spraying and vegetation sowing. Usually, users can send control commands to plant protection drones through the control terminal. The plant protection drones can perform corresponding agricultural operations such as spraying and sowing according to the received control commands.

[0065] Of course, the control instruction may also carry execution parameters, which may include, for example, a spraying interval, the amount of liquid sprayed each time, a sowing interval, the amount of crop seeds sown each time, and the like.

[0066] Figure 1 The structure diagram of the existing drone provided by the embodiment of the present application is shown as follows: Figure 1 As shown, the existing UAV includes multiple electronic speed regulators and loads matched with each electronic speed regulator, wherein the multiple electronic speed regulators are respectively recorded as electronic speed regulator 1, electronic speed regulator 2...electronic speed regulator n, and the loads matched with each electronic speed regulator are respectively recorded as load 1, load 2...load n.

[0067] Among them, the electronic speed controller is referred to as ESC, which is used to adjust the speed of the motor. Usually, according to the different motors, the electronic speed controller can be divided into brushed ESC and brushless ESC.

[0068] The loads matched with each electronic speed regulator may include a spraying device, a sowing device, etc., wherein the spraying device includes a spraying motor, which is used to spray liquid to the area where the crops are located under the action of the spraying motor. The liquid may include pesticides, herbicides, etc., and the sowing device includes a sowing motor. The sowing circuit is used to sow crop seeds, etc. to the designated area under the action of the sowing motor.

[0069] It can be seen from this that existing drones need to use multiple electronic speed regulators, which results in high hardware costs for drones and high maintenance complexity.

[0070] Based on this, the present application provides a load control device, which can input an electrical signal corresponding to the load into the processing module according to the different connected loads. The processing module can output a control signal matching the load type according to the input electrical signal, which not only saves hardware costs but also reduces maintenance complexity.

[0071] The contents disclosed in this application are described in detail below with reference to several specific embodiments.

[0072] Figure 2 The structure of the load control device provided in the embodiment of the present application is shown in FIG. Figure 1 ,like Figure 2As shown, the load control device 10 includes: a processing module 100 and a switching module 200, the output end OUT of the switching module 200 is connected to the input end IN of the processing module 100, the input end IN of the switching module 200 is used to connect the load, the output end OUT of the processing module 100 is used to connect the load 300, the switching module 200 is used to input an electrical signal corresponding to the load 300 to the processing module 100 after connecting the load 300, the processing module 100 is used to determine the type of the load 300 according to the electrical signal input by the switching module 200, and output a control signal matching the type of the load 300.

[0073] The load control device 10 may be an electronic speed regulator.

[0074] Among them, the load 300 may include a spraying device and a sowing device. The spraying device may include a spraying motor, which is used to spray liquid to the area where the crops are located under the action of the spraying motor. The liquid may include pesticides, herbicides, etc. The sowing device includes a sowing motor, and the sowing circuit is used to sow crop seeds, etc. to the designated area under the action of the sowing motor.

[0075] Of course, the above description is only based on the example that the load 300 includes a spraying device and a spreading device. In actual applications, the load 300 includes but is not limited to the above two types.

[0076] The input terminal IN of the switching module 200 is used to connect the load 300, and the output terminal OUT of the switching module 200 is connected to the input terminal IN of the processing module 100. The switching module 200 is used to input an electrical signal corresponding to the load 300 to the processing module 100 after connecting the load 300. That is to say, when different types of loads 300 are connected, the switching module 200 can output electrical signals of different sizes. In this way, the switching module 200 can input an electrical signal corresponding to the load 300 to the processing module 100.

[0077] It should be noted that the connected load 300 can be determined based on the received control instructions, that is, the user can remotely operate the control terminal to send control instructions to the load control device 10, and the load control device 10 can make the switching module 200 connect to the corresponding load 300 according to the received control instructions, wherein the control instructions may include the type of load 300.

[0078] The processing module 100 may be an electronic speed regulator, the output end OUT of the processing module 100 is used to connect the load 300, the input end IN of the processing module 100 is connected to the output end OUT of the switching module 200, the load 300 is connected to the switching module 200, and an electrical signal corresponding to the load 300 is input to the processing module 100. The processing module 100 may determine the type of the load 300 connected to the switching module 200 according to the electrical signal, and output a control signal matching the type of the load 300 to control the load 300 to perform a corresponding operation, that is, different types of loads 300 may correspond to an electrical signal range, for example, the electrical signal range [0V, 0.5V] corresponds to load 1, and the electrical signal range [3.0V, 3.3V] corresponds to load 2, then the processing module 100 may determine the type of the load 300 according to the electrical signal input by the switching module 200, the type of the load 300 may be, for example, a spraying device, and then output a control signal matching the type of the load 300, that is, output a control signal matching the spraying device to control the spraying device to spray liquid to the area where the crops are located.

[0079] The load control device of this embodiment includes a processing module and a switching module. The output end of the switching module is connected to the input end of the processing module. The input end of the switching module is used to connect the load. The output end of the processing module is used to connect the load. The switching module is used to input an electrical signal corresponding to the load to the processing module after connecting the load. The processing module is used to determine the type of the load according to the electrical signal input by the switching module, and output a control signal matching the type of the load. In this embodiment, the electrical signal corresponding to the load is input to the processing module according to the different connected loads. The processing module can output a control signal matching the load type according to the input electrical signal. Compared with the prior art, multiple load control devices are not required, which not only saves hardware costs but also reduces maintenance complexity.

[0080] exist Figure 2 Based on the examples, Figure 3 The structure of the load control device provided in the embodiment of the present application is shown in FIG. Figure 2 ,like Figure 3 As shown, the switching module 200 includes: a switch unit 210, the output end OUT of the switch unit 210 is connected to the input end IN of the processing module 100, the input end IN of the switch unit 210 is connected to the load 300, the ground end G of the switch unit 210 is grounded, and the power supply end V of the switch unit 210 is connected to the voltage end.

[0081] The input terminal IN of the switching module 200 is the input terminal IN of the switch unit 210 , and the output terminal OUT of the switching module 200 is the output terminal OUT of the switch unit 210 .

[0082] The input terminal IN of the switch unit 210 is connected to the load 300, the ground terminal G of the switch unit 210 is grounded, and the power supply terminal V of the switch unit 210 is connected to the voltage terminal. In this way, when the switch unit 210 is connected to different loads 300, different electrical signals can be output; the output terminal OUT of the switch unit 210 is connected to the input terminal IN of the processing module 100, and the output terminal OUT of the switch unit 210 can output an electrical signal corresponding to the load 300. The processing module 100 can determine the type of the load 300 according to the electrical signal input by the switch unit 210, and then output a control signal matching the type of the load 300. Through such a design, only one load control device 10 is needed to control different types of loads 300, which not only saves hardware costs but also reduces maintenance complexity.

[0083] In an optional implementation, the switching module 200 is specifically used for:

[0084] After the load 300 is connected, the switch unit 210 is turned on or off under the action of the load 300 , and an electrical signal is input to the processing module 100 accordingly.

[0085] That is to say, when the input terminal IN of the switch unit 210 is connected to different loads 300, the switch unit 210 can be automatically turned on or off under the action of the load 300. Since the output terminal OUT of the switch unit 210 is connected to the input terminal IN of the processing module 100, the input terminal IN of the switch unit 210 is connected to the load 300, the ground terminal G of the switch unit 210 is grounded, and the power supply terminal V of the switch unit 210 is connected to the voltage terminal V, then different electrical signals can be output when the switch unit 210 is turned on or off.

[0086] refer to Figure 3 , taking the load 300 including a spraying device and a sowing device, and the power supply end of the switch unit 210 connected to the 3.3V voltage end as an example, the voltage detection point is recorded as P. If the spraying device is connected, the switch unit 210 can be closed, then the voltage of the voltage detection point P can be 3.3V, and accordingly, the output end of the switch unit 210 can be a voltage of 3.3V. The voltage of the input end of the processing module 100 is 3.3V, then the processing module 100 can determine the type of load 300 corresponding to the input 3.3V according to the preset electrical signal range, and output a control signal matching the type of load 300, that is, output a control signal corresponding to the spraying device.

[0087] Similarly, if a spreading device is connected, the switch unit 210 can be open, and the voltage at the voltage detection point P can be 0V. Correspondingly, the output end of the switch unit 210 can be a voltage of 0V, and the voltage at the input end of the processing module 100 is 0V. Then the processing module 100 can preset the electrical signal range, determine the type of load 300 corresponding to the input 0V, and output a control signal matching the type of load 300, that is, output a control signal corresponding to the spreading device.

[0088] The load control device of this embodiment, the switching module includes: a switch unit, the output end of the switch unit is connected to the input end of the processing module, the input end of the switch unit is connected to the load, the ground end of the switch unit is grounded, and the power supply end of the switch unit is connected to the voltage end. This embodiment switches the switch unit to input different electrical signals to the processing module, and then the processing module can output a control signal matching the load type according to the input electrical signal. Compared with the prior art, multiple load control devices are not required, which not only saves hardware costs but also reduces maintenance complexity.

[0089] exist Figure 3 Based on the examples, Figure 4 The structure of the load control device provided in the embodiment of the present application is shown in FIG. Figure 3 ,like Figure 4 As shown, the switching module 200 also includes: a first resistor 220 and a second resistor 230, the first resistor 220 is arranged between the power supply terminal V of the switch unit 210 and the ground terminal G of the switch unit 210, and the second resistor 230 is arranged between the input terminal IN of the switch unit 210 and the output terminal OUT of the switch unit 210.

[0090] That is, one end of the first resistor 220 is connected to the ground terminal G of the switch unit 210, the other end of the first resistor is connected to the power supply terminal V of the switch unit 210, one end of the second resistor 230 is connected to the input terminal IN of the switch unit 210, and the other end of the second resistor 230 is connected to the output terminal OUT of the switch unit 210.

[0091] When different loads 300 are connected, the switch unit 210 can be turned on or off, thus resulting in Figure 3 The voltage values ​​of the voltage detection points shown are different, and accordingly, the electrical signal at the input terminal IN of the processing module 100 is also different. Since the voltage at the voltage detection point may fluctuate, for example, fluctuate between 0V-1V, causing the electrical signal at the input terminal of the processing module 100 to fluctuate, a second resistor 230 can be set at the input terminal IN of the switch unit 210 and the output terminal OUT of the switch unit 210. The second resistor 230 plays a role of current limiting and filtering, thereby reducing the fluctuation of the electrical signal at the input terminal of the processing module 100.

[0092] The first resistor 220 may be a pull-up resistor, which plays a role in current limiting and circuit protection.

[0093] As an example, the resistance of the first resistor 220 may be 1 ohm, and the resistance of the second resistor 230 may be 10 kilo-ohms. In practical applications, the specific resistances of the first resistor 220 and the second resistor 230 may be selected according to actual conditions, and this embodiment does not specifically limit this.

[0094] In the load control device of this embodiment, the switching module further includes: a first resistor and a second resistor, wherein the first resistor is arranged between the power supply end of the switch unit and the ground end of the switch unit, and the second resistor is arranged between the input end of the switch unit and the output end of the switch unit. This can not only reduce voltage fluctuations, but also protect the circuit.

[0095] exist Figure 4 Based on the examples, Figure 5 The structure of the load control device provided in the embodiment of the present application is shown in FIG. Figure 4 ,like Figure 5 As shown, the input terminal IN of the processing module 100 includes: a first interface 110 .

[0096] The processing module 100 is specifically used for:

[0097] The logic value corresponding to the electrical signal is obtained based on the analysis of the first interface 110 , the type of the load 300 is determined according to the logic value, and a control signal matching the type of the load 300 is output.

[0098] Among them, the logical value corresponding to the electrical signal can be 0 or 1, that is, when different types of loads 300 are connected, the switch unit 210 can be opened or closed to output an electrical signal corresponding to the load 300. The processing module 100 can parse the electrical signal based on the first interface 110 to obtain the logical value corresponding to the electrical signal, determine the type of load 300 according to the logical value obtained by parsing, and output a control signal matching the type of load 300.

[0099] It should be noted that if the load 300 includes two types, the processing module 100 can pre-set the correspondence between the load 300 type and its corresponding logical value. For example, the logical value corresponding to the spraying device is set to 1, and the logical value corresponding to the spreading device is set to 0. Then, when the load 300 is connected, the switch unit 210 transmits the electrical signal corresponding to the load 300 to the processing module 100. The processing module 100 can parse the electrical signal based on the first interface 110 to obtain the logical value corresponding to the electrical signal, and determine the type of load 300 according to the pre-set correspondence between the load 300 type and its corresponding logical value, and then output a control signal that matches the type of load 300.

[0100] Optionally, the processing module 100 may include, for example, a microcontroller unit (MCU).

[0101] refer to Figure 3 , taking the load 300 including a spraying device and a sowing device, the power supply end of the switch unit 210 is connected to the 3.3V voltage end, the logic value corresponding to the spraying device is set to 1, and the logic value corresponding to the sowing device is set to 0 as an example, the voltage detection point is recorded as P, if the spraying device is connected, the switch unit 210 can be automatically closed, then the voltage of the voltage detection point P can be 3.3V, the switch unit 210 outputs a 3.3V voltage, the output end of the switch unit 210 is connected to the input end of the MCU, and the input end of the MCU includes: a first interface (GPIO_Input) 110, then the MCU can parse the first interface 110 to obtain a logic value corresponding to the electrical signal of 1, determine the type of the load 300 as a spraying device according to the logic value, and output a control signal matching the spraying device.

[0102] Similarly, if a spreading device is connected, the switch unit 210 can be automatically opened, and the voltage at the voltage detection point P can be 0V. Correspondingly, the output end of the switch unit 210 can be a voltage of 0V. Then the MCU can parse the electrical signal based on the first interface 110 to obtain a logical value of 0 corresponding to the electrical signal, determine that the type of load 300 is a spreading device according to the logical value, and output a control signal that matches the spreading device.

[0103] It should be noted that the first interface 110 of the processing module 100 can parse the electrical signal output by the switch unit 210 into a corresponding logical value according to the preset electrical signal range and the parsing rules of the logical value. For the preset electrical signal range and the parsing rules of the logical value, please refer to the relevant description in the prior art, which will not be repeated here.

[0104] In the load control device of this embodiment, the input end of the processing module includes: a first interface, and the processing module is specifically used to: obtain a logical value corresponding to the electrical signal based on the first interface analysis, determine the type of the load according to the logical value, and output a control signal matching the type of the load. In this embodiment, according to the different connected loads, the logical value corresponding to the load is input to the processing module, and the processing module can determine the type of the load according to the logical value, and output a control signal matching the type of the load. Compared with the prior art, multiple load control devices are not required, which not only saves hardware costs, but also reduces maintenance complexity.

[0105] exist Figure 4 Based on the examples, Figure 6 The structure of the load control device provided in the embodiment of the present application is shown in FIG. Figure 5 ,like Figure 6As shown, the input end of the processing module 100 includes: a second interface 120 .

[0106] The processing module 100 is specifically used to obtain a sampled voltage value of the electrical signal based on sampling of the second interface 120 , determine the type of the load 300 according to the sampled voltage value, and output a control signal matching the type of the load 300 .

[0107] Among them, the second interface 120 of the processing module 100 can be an interface with an analog-to-digital converter (ADC) sampling function. When different types of loads 300 are connected, the switch unit 210 can be turned on or off to output an electrical signal corresponding to the load 300. The processing module 100 can obtain a sampled voltage value of the electrical signal based on the sampling of the second interface 120, determine the type of the load 300 according to the sampled voltage value, and output a control signal matching the type of the load 300.

[0108] It should be noted that the processing module 100 can pre-set the corresponding relationship between the load 300 type and its corresponding sampling voltage value, refer to Figure 3 For example, the sampling voltage value corresponding to the spraying device is set to 3.3V, and the logic value corresponding to the sowing device is set to 0. Of course, in order to prevent circuit influence and to distinguish more accurately, the sampling voltage value corresponding to the spraying device can also be set to a voltage range, for example, the sampling voltage value range corresponding to the spraying device is set to [3.0V, 3.3V], and the sampling voltage value range corresponding to the sowing device is set to [0, 0.3V]. In this way, when the load 300 is connected, the switch unit 210 transmits the electrical signal corresponding to the load 300 to the processing module 100. The processing module 100 can obtain the sampling voltage value of the electrical signal based on the sampling of the second interface 120, and determine the type of the load 300 according to the predetermined correspondence between the load 300 type and its corresponding sampling voltage value, and output a control signal matching the type of the load 300.
