[0018] The positioning control unit identifies whether the self-moving device is located in a preset safe zone based on the location information.

[0019] As a further improvement to the embodiments of this application, the self-moving device further includes an interaction module, which is communicatively connected to the power supply identification module and the control module respectively;

[0020] The interaction module includes a display component; when the self-moving device is powered off, the control module controls the self-moving device to enter a locked state and displays the locked state through the display component.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0042] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by a person skilled in the art to which this application pertains. The terms "comprising" or "including," or similar words used in the embodiments of this application, mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0043] It should be noted that although this application provides method operation steps as shown in the following embodiments or figures, the method may include more or fewer operation steps based on conventional or non-inventive effort. For steps that do not logically have a necessary causal relationship, the execution order of these steps is not limited to the execution order provided in the embodiments of this application.

[0044] As described in the background section, in related self-moving devices, such as lawnmowers, the positioning module and alarm module are independently configured. The positioning module is powered by the device's internal power supply. When the self-moving device loses power, the positioning module also loses power, and at this time, the positioning module can no longer provide positioning information to the lawnmower. While the alarm module can be powered by its own battery after the lawnmower loses power, even if it provides a loud alarm, it is difficult for the user to determine the lawnmower's location through the alarm signal if the lawnmower is stolen or moved to a distant location.

[0045] Therefore, the positioning and alarm modules in the relevant self-moving devices cannot accurately indicate the location of the lawnmower robot, and improvements are needed.

[0046] Based on this, this application provides a self-moving device that can realize power-off location alarm.

[0047] Self-moving devices can move and work autonomously. In one specific embodiment, the self-moving device is a lawnmower robot. In other embodiments, the self-moving device can also be a sweeping robot, an automatic snow sweeper, a multi-functional machine, etc.

[0048] Among them, self-moving devices can independently complete certain tasks without user input or control during automatic operation; of course, self-moving devices can also receive control commands transmitted from remote terminals and complete corresponding work according to the control commands.

[0049] like Figure 1 , Figure 2 As shown, an embodiment of this application provides a self-moving device (hereinafter also referred to as a "lawn-mowing robot," "device," or "machine"). The self-moving device 100 includes a positioning module 20, an alarm module 30, and a control module 40. The positioning module 20 is used to acquire the location information of the self-moving device 100. The alarm module 30 includes an alarm 31 and an alarm battery assembly 32, the alarm 31 being electrically connected to the alarm battery assembly 32, and the alarm 31 being used to emit an alarm signal.

[0050] The control module 40 is communicatively connected to the positioning module 20 and the alarm module 30, respectively. The control module 40 is configured to control the alarm battery assembly 32 to supply power to the positioning module 20 and the alarm 31, at least when the self-moving device 100 is powered off.

[0051] The aforementioned self-moving device 100 can obtain the device's location information in real time through the positioning module 20, and the alarm module 30 can issue an alarm signal when necessary. When the device is powered off, the control module 40 ensures that the alarm battery assembly 32 supplies power to the positioning module 20 and the alarm 31, so that the self-moving device 100 maintains the positioning and alarm function when the power is off, ensuring that the device can still track the location and trigger an alarm when it is stolen or moved abnormally, thereby enhancing the device's security and anti-theft performance.

[0052] Specifically, alarm 31 is a high-volume alarm used to play preset alarm messages to alert the user that the lawnmower robot has been moved abnormally. Alarm module 30 also includes an alarm control board, which controls the alarm 31 to play the alarm messages.

[0053] like Figure 1 , Figure 2 As shown, in some embodiments, the self-moving device 100 further includes an energy module 50 and a power supply identification module 60. The energy module 50 is used to supply power to the self-moving device 100, and the power supply identification module 60 is used to identify the power supply status of the energy module 50.

[0054] When the power supply identification module 60 identifies that the energy module 50 is supplying power to the self-moving device 100, the control module 40 controls the energy module 50 to supply power to at least the positioning module 20; when the power supply identification module 60 identifies that the energy module 50 stops supplying power, causing the self-moving device 100 to lose power, the control module 40 controls the alarm battery assembly 32 to supply power to the positioning module 20 and the alarm 31.

[0055] Specifically, the energy module 50 serves as the main power source for the self-moving device 100. The voltage on the energy module 50 can be reduced to the voltage used to power the positioning module 20 and the alarm 31 through the step-down unit, thereby enabling the energy module 50 to power the self-moving device 100 while also powering the positioning module 20 and the alarm 31.

[0056] The power supply identification module 60 can dynamically identify the power supply status of the device. Based on the identification result, the control module 40 can switch between power supply from the energy module 50 and power supply from the alarm battery assembly 32 to automatically select the optimal power supply, thus avoiding redundant battery consumption and extending the life of the backup battery. Furthermore, by monitoring the power supply status in real time, it can ensure that the power supply for the positioning and alarm functions can be promptly switched in the event of a power outage.

[0057] It should be noted that the power module 50 supplies power to the self-moving device 100, corresponding to the situation where the self-moving device 100 is powered on and operating stably. The power module 50 stops supplying power, corresponding to the situation where the self-moving device 100 is powered off and disconnected from the power module 50.

[0058] In some situations, such as when the positioning module 20 acquires location information or sends information to the outside, the required power supply current may be relatively large. Alternatively, if the power supply module 50 is insufficient, the positioning module 20 can be powered jointly by the power supply module 50 and the alarm battery assembly 32. The power supply module 50 can also power the positioning module 20 while the alarm battery assembly 32 powers the alarm 31. Furthermore, when the power supply module 50 has sufficient power, it can also charge the alarm battery assembly 32.

[0059] In some embodiments, the alarm battery assembly 32 includes a battery pack and a battery management unit. A first power supply circuit is connected between the battery pack and the positioning module 20, and a second power supply circuit is connected between the energy module 50 and the positioning module 20. The battery management unit can be used to turn on or off the first and second power supply circuits.

[0060] Specifically, after the power supply identification module 60 detects that the self-moving device 100 is powered off, it controls the first power supply circuit to be turned on through the battery management unit, so that the battery pack supplies power to the positioning module 20 and the alarm 31 through the first power supply circuit.

[0061] After the power supply identification module 60 identifies that the energy module 50 is supplying power to the self-moving device 100, it controls the first power supply circuit to be disconnected through the battery management unit and controls the second power supply circuit to be turned on, so that the energy module 50 supplies power to the positioning module 20 and the alarm 31 through the second power supply circuit.

[0062] The first and second power supply circuits each include an enable circuit, which is a circuit structure that controls the on and off states of the control circuit, enabling flexible switching of power supply. For example, when the self-moving device is working normally, the enable circuit connects the energy module 50 to the positioning module 20 and the alarm 31, supplying power through the energy module 50; while when the device is powered off, the enable circuit switches to the alarm battery assembly 32 to supply power to the positioning module 20 and the alarm 31, ensuring the continuous operation of the positioning and alarm functions of the device in different states.

[0063] The first and second power supply circuits are independent of each other, avoiding interference between different power supply entities and improving system stability. The battery management unit controls the circuit's on / off state, ensuring efficient and accurate power switching.

[0064] In one specific embodiment, the power supply identification module 60 includes a voltage detection unit for detecting the voltage of the energy module 50. The voltage detection unit identifies the power supply status of the self-moving device 100, thereby enabling the connection or disconnection of different power supply circuits. Voltage detection is a simple, direct, and effective method for identifying the power supply status, accurately determining whether the energy module 50 is providing normal power to the self-moving device 100, and providing a reliable basis for subsequent power supply switching.

[0065] In one specific embodiment, the self-moving device 100 includes a first connection interface for connecting to the positioning module 20 and a second connection interface for connecting to the alarm module 30. The positioning module 20 is connected to the control module 40 through the first connection interface, and the alarm module 30 is connected to the control module 40 through the second connection interface. The modular interface design facilitates the optional installation of the positioning module 20 and the alarm module 30.

[0066] Specifically, the positioning module 20 and the alarm module 30 are detachably installed on the self-moving device 100. The self-moving device 100 includes a sensing component, which is communicatively connected to the positioning module 20 and the alarm module 30, respectively, and is used to sense the optional status of the positioning module 20 and the alarm module 30.

[0067] In one specific embodiment, the positioning module 20 includes a positioning unit, a signal transmitting unit, and a positioning control unit. The positioning unit is used to acquire the location information of the self-moving device 100, the signal transmitting unit is used to communicate with a remote terminal, and the positioning control unit is communicated with the positioning unit and the signal transmitting unit respectively.

[0068] The control unit identifies whether the self-moving device 100 is located in a preset safe zone based on the location information of the positioning unit. If the self-moving device 100 is located outside the safe zone, the control signal transmitting unit sends the location information to the remote terminal, and can also control the alarm 31 to issue an alarm signal.

[0069] By using location information to determine whether a device has exceeded the safe zone, an alarm can be triggered or location information can be sent. This can be combined with geofencing technology to proactively alarm and send location information when the device moves abnormally, improving anti-theft response speed. Additionally, it supports simultaneous triggering of remote terminal notifications and local high-volume alarms, further enhancing anti-theft effectiveness.

[0070] like Figure 3 As shown, in some embodiments, the self-moving device 100 further includes an interaction module 70, which is communicatively connected to the power supply identification module 60 and the control module 40, respectively.

[0071] The interaction module 70 includes a display component. When the power supply identification module 60 detects a power-off command from the self-moving device 100, the control module 40 controls the self-moving device 100 to enter a locked state, which can be displayed on the display component. In the locked state, the self-moving device 100 cannot be powered on or operated.

[0072] After the control module inputs an unlock command into the interaction module 70, it controls the self-moving device 100 to unlock, and the self-moving device 100 can be restarted and put back into operation.

[0073] The device enters a locked state when powered off and cannot be powered on or operated while locked, further increasing the difficulty of use if the device is stolen and reducing the risk of misuse. The locked state can only be unlocked after an unlock command is entered on the interactive module, providing an additional security guarantee to ensure that only authorized users can use the device.

[0074] Optionally, the display component of the interaction module 70 can be located on the self-moving device 100. The interaction module 70 may also include a remote terminal that is remotely connected to the self-moving device 100.

[0075] Optionally, the interaction module 70 includes a voice interaction unit for remote communication with a remote terminal. By setting up the voice interaction unit, remote interaction between the user and the self-moving device 100 can be achieved. Specifically, the voice interaction unit can be connected to the alarm 31, allowing the user to interact with the lawnmower robot via voice through the remote terminal, prompting the robot's handler to return the robot to its original parking position.

[0076] Overall, taking a lawnmower robot as an example, when the power supply identification module 60 detects a power-off command for the lawnmower robot, the control module 40 controls the lawnmower robot to power down and lock, and the interaction module 70 displays the locked status of the lawnmower robot. At this time, if it is necessary to control the lawnmower robot to power down using the power off button on the lawnmower robot, the control module 40 will interact with the interaction module 70. The power-off password needs to be entered through the interaction module 70 to control the lawnmower robot to power down, thus preventing abnormal movement after power-off and further improving the anti-theft performance of the lawnmower robot.

[0077] Meanwhile, when the power supply identification module 60 detects that the lawnmower robot is powered on and working via the power button, it can also perform power-on interactive control through the interaction module 70. At this time, an unlock command needs to be input through the interaction module 70 to unlock and power on the lawnmower robot, so that the lawnmower robot can be locked and protected even if it is moved abnormally.

[0078] like Figure 4 As shown, other embodiments of this application provide an alarm method for a self-moving device, which will be described using the self-moving device described in the above embodiments as an example. The alarm method for a self-moving device includes the following steps:

[0079] Step S10: Detect the power supply status of the self-moving device;

[0080] Step S21: When the self-moving device is detected to be in a power-off state, the alarm battery component of the alarm module is used to power the positioning module.

[0081] Step S30: The location of the self-moving device is identified by the positioning module. When the self-moving device is detected to have moved out of the preset safe zone, an alarm signal is issued.

[0082] The aforementioned alarm method for self-moving devices detects the device's power supply status and promptly switches to an alarm battery pack to power the positioning module when the device loses power, ensuring the positioning function continues to operate normally even in power outages. Combined with the positioning module's ability to identify the device's location, an alarm signal is emitted when the device moves out of a preset safe zone, enabling timely detection of theft or abnormal movement, significantly enhancing the security and anti-theft capabilities of self-moving devices. Furthermore, even when the device is powered off, the positioning module continues to operate, providing the possibility of tracking the device's location. This gives users a greater chance of recovering their lost or stolen devices, preventing financial loss.

[0083] like Figure 5 As shown, in some embodiments, the alarm method for self-moving devices further includes the following steps:

[0084] Step S22: When the self-moving device is detected to be powered on, the positioning module is powered by the power module of the self-moving device.

[0085] Among them, the intelligent switching of power supply according to the power supply status can make reasonable use of energy, avoid unnecessary power consumption of the alarm battery component, extend the service life of the alarm battery component, and also ensure that the positioning module can work stably under different power supply conditions.

[0086] like Figure 6 As shown, in some embodiments, the alarm method for self-moving devices further includes the following steps:

[0087] Step S23: When it is detected that the self-moving device is in a power-off state, the self-moving device enters a locked state. In the locked state, the self-moving device cannot be powered on and work.

[0088] Step S31: After the unlock command is entered in the interactive module, the self-moving device is unlocked.

[0089] The device enters a locked state when powered off and cannot be powered on or operated while locked, further increasing the difficulty of use if the device is stolen and reducing the risk of misuse. The locked state can only be unlocked after an unlock command is entered on the interactive module, providing an additional security guarantee to ensure that only authorized users can use the device.
