The embodiments of this application will be described below with reference to the accompanying drawings.

[0056] Figure 1 Shown in the figure is a structural schematic diagram of a string releasing control system for a lawn mower provided by this application, as Figure 1 shown, including: a trimming accessory 101 and a lawn mower 102, the trimming accessory 101 is detachably provided on the lawn mower 102; the lawn mower 102 includes: a target button 104; the string releasing control system further includes a controller 105, the controller 105 is provided on the lawn mower 102 or the trimming accessory 101; the trimming accessory 101 includes a trimming motor 103, a trimming head and a trimming string;

[0057] The target button 104 is connected to the controller 105, and is used to generate a string releasing control instruction based on the user's trigger and send the string releasing control instruction to the controller 105;

[0058] The controller 105 is connected to the trimming motor 103, and is used to control the trimming motor 103 to drive the trimming head to rotate according to the string releasing control instruction, so as to control the release of the trimming string.

[0059] In order to improve the accuracy of the string releasing timing, a target button 104 can be provided on the lawn mower 102. The user can judge whether the string releasing operation needs to be performed currently. When the string releasing operation needs to be performed, the target button 104 can be triggered to generate a string releasing control instruction, so as to perform the string releasing operation.

[0060] Optionally, a controller 105 can also be provided. The controller 105 can be provided on the lawn mower 102 or on the edge trimming accessory 101. The controller 105 can be connected to the target button 104 to receive the rope releasing control instruction generated when the target button 104 is triggered. The controller 105 can also be connected to the edge trimming motor 103 and can control the edge trimming motor 103 to drive the edge trimming head to rotate based on the rope releasing control instruction. The connections between the controller 105 and the target button 104 and the edge trimming motor 103 are both electrical connections.

[0061] Optionally, when controlling the lawn mower 102 to work, the user can observe the length of the edge trimming rope. When the length of the trimming rope is short, a rope releasing operation can be performed; or, the user can observe the trimming effect. When the trimming effect is not good, a rope releasing operation can be performed.

[0062] Optionally, the way for the user to trigger the target button 104 can be: clicking the target button 104 to generate a rope releasing control instruction; or, long-pressing the target button 104 to generate a rope releasing control instruction. When long-pressing the target button 104, the rope releasing operation can be stopped when the user stops pressing the target button 104.

[0063] The rope releasing control system for a lawn mower provided by the present application includes: an edge trimming accessory 101 and a lawn mower 102. The edge trimming accessory 101 is detachably provided on the lawn mower 102. The lawn mower 102 includes: a target button 104. The rope releasing control system further includes a controller 105. The controller 105 is provided on the lawn mower 102 or on the edge trimming accessory 101. The edge trimming accessory 101 includes an edge trimming motor 103, an edge trimming head, and a trimming rope. The target button 104 is connected to the controller 105 and is used to generate a rope releasing control instruction based on the user's trigger and send the rope releasing control instruction to the controller 105. The controller 105 is connected to the edge trimming motor 103 and is used to control the edge trimming motor 103 to drive the edge trimming head to rotate according to the rope releasing control instruction so as to control the release of the trimming rope. By providing the target button 104 on the lawn mower 102, when the user determines that the trimming rope needs to be released, the target button 104 is triggered to realize the release of the trimming rope, and the accuracy of the rope releasing timing is improved by the user sending the rope releasing control instruction.

[0064] Optionally, the target button 104 is a rope releasing function button.

[0065] When the lawn mower 102 is in the edge trimming mode, the trimming rope of the edge trimming accessory 101 trims the grass, and the rope releasing function button is used to generate the rope releasing control instruction.

[0066] Alternatively, when the lawn mower 102 is in the mowing mode, the trimming line of the trimming accessory 101 does not mow the grass, and the string release function button is used to generate other control instructions other than the string release control instruction.

[0067] When triggering the string release control instruction through the target button 104 on the lawn mower 102, a string release function button can be set on the lawn mower 102, and the string release control instruction is generated by triggering the string release function button.

[0068] Optionally, the trimming accessory 101 is set on the lawn mower 102 as an accessory of the lawn mower 102, and a cutter head is also set on the lawn mower 102. Therefore, the lawn mower 102 can be in two modes for weed removal. One is the mowing mode, that is, mowing the grass by starting the cutter head. At this time, the trimming line of the trimming accessory 101 does not mow the grass; the other is the trimming mode, that is, removing weeds by starting the trimming accessory 101, that is, the trimming line of the trimming accessory 101 mows the grass.

[0069] In order to improve the usage rate of the string release function button, when the lawn mower 102 is in the trimming mode, it can be used to generate the string release control instruction; when the lawn mower 102 is not in the trimming mode, it can be used to generate other control instructions. Exemplarily, when the lawn mower 102 is in the mowing mode, it can control the rotation speed of the cutter head, etc.

[0070] By setting the string release function button and setting different functions for the string release function button when the lawn mower 102 is in different modes, the rational utilization of the string release function button is improved, so that there is no need to set more buttons to implement different functions, and the user experience is improved.

[0071] Optionally, the controller 105 is further configured to make the trimming mode available when detecting that the trimming accessory 101 is installed on the lawn mower 102; the controller 105 is further configured to make the trimming mode unavailable when detecting that the trimming accessory 101 is not installed on the lawn mower 102.

[0072] The trimming accessory 101 is detachably set on the lawn mower 102. Only when the trimming accessory 101 is installed on the lawn mower 102, the lawn mower 102 may adopt the trimming mode; when the trimming accessory 101 is not installed on the lawn mower 102, the lawn mower 102 cannot be in the trimming mode. Therefore, when controlling the lawn mower 102 to switch modes, the controller 105 can first detect whether the trimming accessory 101 is installed on the lawn mower 102, so as to determine whether the trimming mode is available.

[0073] Optionally, a pressure sensor may be provided at the position where the edging accessory 101 is installed in the lawn mower 102. When the pressure sensor detects the presence of a pressure value or a pressure value greater than a certain value, it indicates that the edging accessory 101 is installed on the lawn mower 102; otherwise, it indicates that the edging accessory 101 is not installed on the lawn mower 102. The pressure sensor may be connected to the controller 105, so that the controller 105 can determine whether the edging accessory 101 is installed on the lawn mower 102.

[0074] By detecting whether the edging accessory 101 is installed on the lawn mower 102 through the controller 105, it can be accurately determined whether the lawn mower 102 can be in the edging mode, improving the accuracy when the lawn mower 102 switches from the mowing mode to the edging mode.

[0075] Optionally, the target button 104 is the power on / off button provided on the lawn mower 102;

[0076] When the lawn mower 102 is in the edging mode, the power on / off button is used to generate the rope release control instruction;

[0077] Or, when the lawn mower is in the mowing mode, the power on / off button is used to generate a start / stop instruction for controlling the lawn mower 102 to start mowing or stop mowing.

[0078] When triggering the rope release control instruction through the target button 104 on the lawn mower 102, the power on / off button of the lawn mower 102 can also be used to generate the rope release control instruction. This is because a power on / off button is usually provided on the lawn mower 102, and in the mowing mode, the start and stop of the lawn mower 102 can be controlled through the power on / off button. Therefore, it is considered that in the edging mode, the power on / off button can be used to control the edging accessory 101 to start or stop releasing the rope.

[0079] By multiplexing the power on / off button, there is no need to separately set a button for the rope release operation, which can reduce the hardware cost of the lawn mower 102, reduce the complexity of the internal circuit of the lawn mower 102, and in addition, by reducing the number of buttons, the user experience can be improved.

[0080] Optionally, the target button is a combination button; the combination button includes at least a first button and a second button;

[0081] The combination button is used to generate the rope release control instruction when the first button and the second button are triggered simultaneously.

[0082] There may be multiple buttons provided on the lawn mower 102, which are respectively used to implement different functions. When it is necessary to generate the rope release control instruction, there is no need to specially set a new button, and the rope release control instruction can be generated based on some buttons already provided on the lawn mower 102.

[0083] Optionally, a combination key can be set. The combination key can include at least two keys, such as a first key and a second key. When the user triggers the first key and the second key simultaneously, a rope release control instruction can be generated, thus enabling the generation of a rope release control instruction in the edge trimming mode without setting a new key.

[0084] Generating a rope release control instruction by means of a combination key can reduce the hardware cost of the lawn mower 102, reduce the complexity of the internal circuit of the lawn mower 102, and improve the user experience.

[0085] Optionally, the lawn mower 102 further includes a length detection module and a prompt module;

[0086] The length detection module is connected to the controller 105 and is used to detect the current length of the trimming rope and send the current length to the controller 105;

[0087] The controller 105 is connected to the prompt module and is used to output a prompt signal when the current length is less than a first target length and send the prompt signal to the prompt module;

[0088] The prompt module is used to output prompt information according to the prompt signal; the prompt information is used to remind the user to perform an operation of releasing the trimming rope.

[0089] The length detection module can detect the current length of the trimming rope, and the length detection module can be connected to the controller 105, so as to send the current length to the controller 105.

[0090] The controller 105 can output a prompt signal when detecting that the current length is less than the first target length. Optionally, a comparator can be set in the controller, and the current length and the first target length can be compared by the comparator, and a comparison result can be output.

[0091] When the controller 105 receives the prompt signal, it can send it to the prompt module. Optionally, the prompt module can be a sound device or a light-emitting device arranged on the lawn mower 102, so as to emit sound or flash based on the prompt signal of the controller 105.

[0092] The prompt information output by the prompt module can remind the user to perform an operation of releasing the trimming rope.

[0093] By setting the length detection module and the prompt module, it is possible to automatically detect the current length of the trimming rope and notify the user, avoiding the user's frequent attention to whether the trimming rope needs to be released, and also avoiding the problem of poor trimming effect when the rope needs to be released but the user does not notice, so as to realize timely release of the trimming rope.

[0094] Optionally, the length detection module is at least one of an infrared device, an image recognition device, and a force feedback pressure sensor;

[0095] The infrared device is configured to detect the current length of the trimming rope based on the emitted infrared rays;

[0096] The image recognition device is configured to detect the current length of the trimming rope based on the trimming effect information of the mowed area;

[0097] The force feedback pressure sensor is configured to obtain the force feedback information when the trimming head rotates, and detect the current length of the trimming rope according to the force feedback information.

[0098] There can be multiple implementation manners for the length detection module. At least one of an infrared device, an image recognition device, and a force feedback pressure sensor can be set on the lawn mower 102 to implement the detection of the current length.

[0099] The infrared device can emit infrared rays, and the current length of the trimming rope can be detected based on the emitted infrared rays.

[0100] The image recognition device can take pictures of the mowed area. Based on the pictures, the trimming effect can be determined, and the current length can be determined according to the trimming effect. Exemplarily, the image recognition device can collect pictures of the mowed area, and upload the collected pictures to the server for processing. The server can determine the trimming effect based on a pre-trained neural network model, determine the current length based on the trimming effect, and send the determined current length to the image recognition device.

[0101] The force feedback pressure sensor can be set on the trimming head. When the trimming head rotates, there will be force feedback (resistance), and this force feedback is related to the current length of the trimming rope. If the current length is larger, the force feedback is larger; if the current length is smaller, the force feedback is smaller. The force feedback pressure sensor can transmit the force feedback information to the controller 105, so that the controller 105 can determine the current length based on this force feedback information.

[0102] By setting the above devices, the current length of the trimming rope can be accurately detected, so as to accurately send a prompt message to the controller 105.

[0103] Optionally, the lawn mower 102 further includes a timing module;

[0104] The timing module is connected to the controller 105, and is configured to perform a timing operation according to a start timing instruction, and send a stop signal to the controller 105 when the timing value is equal to a preset duration; the start timing instruction is generated when the controller 105 issues the rope release control instruction;

[0105] The controller 105 is configured to receive the stop signal, generate a stop rope release instruction according to the stop signal, and control the edge trimming motor 103 to stop driving the edge trimming head to rotate according to the stop rope release instruction, so as to control the stop of the grass trimming rope release.

[0106] A timing module may also be provided in the lawn mower 102. Based on the timing module, the rope release duration can be controlled to avoid the released grass trimming rope being too long.

[0107] The timing device can be connected to the controller 105 and start timing under the control of the controller 105. Optionally, when the controller 105 generates a rope release control instruction, it can generate a start timing instruction and send it to the timing module, so that the timing module can start timing when starting to release the rope. A preset duration can be set in the timing module. When the timing value of the timing module is equal to the preset duration, a stop signal can be sent to the controller 105.

[0108] When the controller 105 receives the stop signal sent by the timing module, it can generate a stop rope release instruction, thereby stopping the release of the grass trimming rope.

[0109] Optionally, the lawn mower 102 can release the rope at a preset speed when releasing the rope, and a specific length of the grass trimming rope can be released each time according to the preset duration.

[0110] By setting the timing module, the duration of the rope release operation can be detected, so as to stop releasing the rope when the preset duration is reached, and avoid the grass trimming rope being released too long and affecting the grass trimming effect.

[0111] Optionally, the controller 105 is further configured to: when the current length of the grass trimming rope received is greater than or equal to a second target length, generate a stop rope release instruction, and control the edge trimming motor 103 to stop driving the edge trimming head to rotate according to the stop rope release instruction, so as to control the stop of the grass trimming rope release; the second target length is greater than the first target length; the second target length is the maximum allowable rope length.

[0112] In order to avoid the grass trimming rope being released too long and affecting the grass trimming effect, in addition to setting the timing module, the current length of the grass trimming rope can also be detected based on a length detection module. When the current length is greater than or equal to the second target length, a stop rope release instruction can be generated to realize the stop of the grass trimming rope release.

[0113] Optionally, after the user triggers the target button to generate a rope release control instruction, the length detection module can detect the current length of the grass trimming rope and send the detected current length to the controller 105. The controller 105 can generate a stop rope release instruction when the current length is greater than or equal to the second target length, thereby controlling the stop of the grass trimming rope release.

[0114] Optionally, the second target length can be the maximum allowable rope length preset inside the lawn mower, that is, the maximum allowable rope length after the rope release operation.

[0115] By presetting the second target length and detecting the current length of the trimming rope, the rope release can be stopped when the maximum allowable rope length is reached, avoiding the trimming rope from being released too long and affecting the trimming effect.

[0116] Optionally, the target button is arranged on the side trimming accessory.

[0117] When the side trimming accessory is detachably arranged on the lawn mower, the setting position of the target button can also be on the side trimming accessory.

[0118] By arranging the target button on the side trimming accessory, it is convenient for the user to generate a rope release control instruction by triggering the target button when installing or disassembling or inspecting the side trimming accessory, improving the user experience.

[0119] Optionally, the target button is arranged at a target position on the upper surface of the lawn mower; the target position is a position close to the side and the rear of the lawn mower. The target button can be arranged at any position of the lawn mower. For the convenience of the user's operation, the target button can be arranged at the target position on the upper surface of the lawn mower.

[0120] Figure 2 The structural schematic diagram of a lawn mower provided by the present application is shown as Figure 2 shown, the target button is arranged at a position on the upper surface of the lawn mower close to the side and the rear.

[0121] By limiting the position of the target button on the lawn mower, it is convenient for the user to operate the target button, so as to facilitate the user to issue a rope release control instruction.

[0122] Figure 3 The structural schematic diagram of another rope release control system for a lawn mower provided by the present application is shown as Figure 3 shown, the present application also provides a rope release control system for a lawn mower, including: a side trimming accessory 101 and a lawn mower 102, the side trimming accessory 101 is detachably arranged on the lawn mower 102; the lawn mower 102 includes: a remote control signal receiving device 106; the rope release control system further includes a controller 105, the controller 105 is arranged on the lawn mower 102 or the side trimming accessory 101; the side trimming accessory 101 includes a side trimming motor 103, a side trimming head and a trimming rope;

[0123] The remote control signal receiving device 106 is connected to the controller 105 and is configured to receive a rope releasing control instruction sent by a remote control device and send the rope releasing control instruction to the controller 105;

[0124] The controller 105 is connected to the edge trimming motor 103 and is configured to control the edge trimming motor 103 to drive the edge trimming head to rotate according to the rope releasing control instruction, so as to control the release of the grass trimming rope.

[0125] In order to achieve the accuracy of the grass trimming rope release timing, in addition to setting a target button on the lawn mower 102, the lawn mower 102 can also be controlled by a remote control device to perform a rope releasing operation.

[0126] The remote control device can be a remote control device for controlling the lawn mower 102, or can also be a terminal device. An application program can be set on the terminal device to achieve remote control of the lawn mower 102. Optionally, when the remote control device is a terminal device, a rope releasing function control can be set on the terminal device, and a user triggering the rope releasing function control can generate a rope releasing control instruction. Or, a rope releasing control instruction can also be generated based on the currently set controls on the terminal device, such as by triggering two controls simultaneously.

[0127] In order to achieve the control of the lawn mower 102 by the remote control device, a remote control signal receiving device 106 can be set on the lawn mower 102. The remote control signal receiving device 106 can be a Bluetooth module, a 4G module, a 5G module, etc., to achieve wireless transmission between the remote control device and the lawn mower 102.

[0128] When the user determines that a rope releasing operation needs to be performed, a rope releasing control instruction can be issued on the side of the remote control device, and the rope releasing control instruction can be transmitted to the remote control signal receiving device 106 in the lawn mower 102. Further, the remote control signal receiving device 106 can send the rope releasing control instruction to the controller 105, so that the controller 105 can control the edge trimming motor 103 to perform a rope releasing operation.

[0129] The rope release control system for a lawn mower provided by this application includes: a trimming accessory 101 and a lawn mower 102, where the trimming accessory 101 is detachably arranged on the lawn mower 102; the lawn mower 102 includes: a remote control signal receiving device 106; the rope release control system further includes a controller 105, and the controller 105 is arranged on the lawn mower 102 or the trimming accessory 101; the trimming accessory 101 includes a trimming motor 103, a trimming head and a trimming rope; the remote control signal receiving device 106 is connected to the controller 105 and is used to receive the rope release control instruction sent by the remote control device and send the rope release control instruction to the controller 105; the controller 105 is connected to the trimming motor 103 and is used to control the trimming motor 103 to drive the trimming head to rotate according to the rope release control instruction, so as to control the release of the trimming rope. By arranging the remote control signal receiving device 106 on the lawn mower 102, when the user determines that the trimming rope needs to be released, the user sends the rope release control instruction through the remote control device, and based on the remote control signal receiving device 106, the rope release control instruction is transmitted to the controller 105, and the accuracy of the rope release timing is improved by the user's triggering of the remote control device.

[0130] Optionally, the remote control signal receiving device 106 is further used to receive the third target length sent by the remote control device and send the third target length to the controller 105; the third target length is the maximum allowable rope length input by the user on the remote control device.

[0131] In order to further improve the user experience, the user can also set the third target length through the terminal device, and then release the rope based on the third target length. The user can customize the third target length according to needs, so that the user can set different third target lengths according to different scenarios.

[0132] After the terminal device receives the third target length set by the user, it can send the third target length to the controller 105 of the lawn mower 102, and the controller 105 can control the release of the trimming rope based on the third target length.

[0133] Optionally, the third target length can be the maximum allowable rope length when the trimming rope release ends. Correspondingly, when the controller 105 receives the third target length, it can determine the corresponding target resistance, and the target resistance is positively correlated with the third target length. When the controller 105 controls the trimming motor 103 to drive the trimming head to rotate, it can receive the force feedback information uploaded by the trimming accessory 101, that is, the force feedback information when the trimming head rotates. When the force feedback information is greater than or equal to the target resistance, the controller 105 can generate a stop rope release instruction to control the trimming motor 103 to stop driving the trimming head to rotate.

[0134] Optionally, when controlling the grass trimmer 102 to release the string through the terminal device, the third target length can be sent to the controller 105 of the grass trimmer 102 after being set by the user on the terminal device, or when the user issues a string release control instruction on the terminal device, the string release control instruction and the third target length can be sent to the controller 105 of the grass trimmer 102 simultaneously.

[0135] By setting the third target length on the terminal device by the user, it is possible to control the grass trimmer 102 to release the trimming string according to the specified length. The user can set or modify the third target length according to actual needs, improving the user experience.

[0136] Optionally, the string release control instruction is generated when the string release function control on the remote control device is triggered by the user, or the string release control instruction is generated when the remote control device recognizes a target operation; the target operation is at least one of the following: target gesture, target action, or target voice.

[0137] When issuing the string release control instruction through the terminal device, a string release function control can be set on the terminal device, and when the user triggers the string release function control, a string release control instruction can be generated.

[0138] Alternatively, a target gesture, target action, or target language can be preset and stored in advance. When the user makes the corresponding gesture, action, or voice, a string release control instruction can be generated. Exemplarily, it can be recognized whether it is a target gesture through the camera on the terminal device.

[0139] Optionally, the target action can be a certain pattern drawn by the user on the terminal device.

[0140] By setting various target operations for triggering the string release control instruction, it is convenient for the user to issue the string release control instruction based on the terminal device in any of these ways, improving the convenience of issuing the string release control instruction.

[0141] Optionally, the string release control instruction is the string release speed at different times;

[0142] The controller 105 is further configured to: control the side trimming motor 103 to drive the side trimming head to rotate according to the string release speed at different times, so as to control the release of the trimming string; the string release speed at different times is continuously sent to the remote control signal receiving device 106 by the remote control device through the polling interface; the string release speed at different times is determined by the string release length input by the user on the remote control device and the time when the user triggers the string release control instruction.

[0143] The third target length set by the user through the terminal device can also be the length released by the lawn mower each time it performs a rope release operation. For example, if the length is 30 cm, when the lawn mower performs a rope release operation, it releases a 30 cm length of the trimming line.

[0144] At this time, the terminal device does not need to send the third target length or the information representing the third target length to the controller 105 through the remote control signal receiving device 106. Instead, the terminal device can continuously send rotation information to the controller 105 through the remote control signal receiving device 106, so that the controller 105 of the lawn mower 102 controls the trimming motor 103 to drive the trimming head to rotate according to the rotation information.

[0145] Optionally, the terminal device can send rotation information through a polling interface (an interface provided by an application program set on the terminal device to the lawn mower). The rotation speed, that is, the rope release speed, is always transmitted in the polling interface. When no rope release is required, the rotation speed is 0. When the user triggers the target operation, the rotation speed changes from 0 to the specified rope release speed. Optionally, preset values of the rotation speed and rotation duration of the trimming head corresponding to different third target lengths are stored in the application program, so as to transmit rotation information according to the preset values.

[0146] Exemplarily, when the third target length is 30 cm, the corresponding rotation speed is 3000 and the rotation duration is 10 seconds. Then, when the user does not trigger the target operation, the rotation speed transmitted in the polling interface is 0. When the user triggers the target operation, the rotation speed is 3000 and 3000 is continuously transmitted within a 10 - second time period, and 0 is transmitted in the time period after 10 seconds. Correspondingly, the controller 105 of the lawn mower 102 can directly control the trimming motor 103 to drive the trimming head to rotate according to the rotation speed received at different times.

[0147] By transmitting the rotation speed corresponding to different times to the lawn mower 102 on one side of the terminal device, it is possible to avoid storing information such as preset rotation speed in the controller 105 of the lawn mower 102, and it can improve the response speed of the lawn mower 102.

[0148] This application also provides a lawn mower, on which a trimming accessory is detachably provided; the lawn mower includes: a target button and a remote control signal receiving device; a controller is provided on the lawn mower or on the trimming accessory; the trimming accessory includes a trimming motor, a trimming head, and a trimming line;

[0150] The remote control signal receiving device is connected to the controller and is used to receive the rope-laying control instruction sent by the remote control device and send the rope-laying control instruction to the controller;

[0151] The controller is connected to the edge trimming motor and is used to control the edge trimming motor to drive the edge trimming head to rotate according to the rope-laying control instruction, so as to control the release of the grass rope.

[0152] Optionally, in order to meet the user's need to control the lawn mower to perform the rope-laying operation in different ways, a target button or a remote control signal receiving device can be set on the lawn mower, or both the target button and the remote control signal receiving device can be set at the same time, so that the user can generate the rope-laying control instruction in two ways respectively, improving the convenience when the user performs the rope-laying operation.

[0153] This application also provides a remote control device for controlling the lawn mower to perform the rope-laying operation; it includes: an input module and a signal sending module;

[0154] The input module is connected to the signal sending module; it is used to receive the user's trigger operation, generate a rope-laying control instruction according to the trigger operation, and send the rope-laying control instruction to the signal sending module;

[0155] The signal sending module is used to send the received rope-laying control instruction to the remote control signal receiving device in the lawn mower to control the lawn mower to release the grass rope.

[0156] For the remote control device, an input module can be set for the user to perform a trigger operation to generate a rope-laying control instruction, and the generated rope-laying control instruction can be sent to the signal sending module.

[0157] In order to transmit the rope-laying control instruction to the lawn mower, a signal sending module can also be set in the remote control device. Exemplarily, the signal sending module can be a 4G module, a 5G module or a Bluetooth module, etc., to realize information transmission with the remote control signal receiving device in the lawn mower.
