[0043] The following is an exemplary description of the control method of the life-saving equipment provided in the present application.

[0044] The control method of the life-saving device provided in the embodiment of the present application can be executed on the life-saving device, and can also be executed on a computing device such as a computer, a server, etc. that is communicatively connected to the life-saving device. The control method of the life-saving device provided in the embodiment of the present application is described below by taking the example that the control method of the life-saving device provided in the embodiment of the present application can be executed on the life-saving device.

[0045] First, the life-saving equipment is introduced.

[0046] Life-saving equipment is a smart device that can be thrown into the water and float on the water.

[0047] The central processing module 11 is communicatively connected with the local driving control unit 12, the water entry sensing unit 13, the posture sensing unit 14, the positioning and orientation unit 15, the human body sensing unit 16, the motor drive unit 17 and the first wireless data communication unit 18, and is used to receive data input by each unit, process the received data, and execute decisions and controls according to the processing results.

[0048] The local driving control unit 12 is used to send the control signal input by the user to the central processing module 11, and the central processing module 11 outputs the corresponding driving signal to the motor driving unit 17 according to the control information.

[0049] The water entry sensing unit 13 may include a temperature sensor or an ultrasonic sensor, and is used to determine whether the lifesaving equipment has entered the water based on the collected information.

[0050] The posture sensing unit 14 may include a posture sensor for determining posture information of the lifesaving device, for example, determining whether the posture information of the lifesaving device is upright or inverted.

[0051] The positioning and orientation unit 15 may include a global positioning system (GPS) or an image sensor, which is used to determine the position and orientation of the lifesaving equipment.

[0052] The human sensing unit 16 may include a human sensor or a pressure sensor for determining whether there is a person driving the lifesaving device.

[0053] The motor drive unit 17 is used to drive the lifesaving device to move forward, turn or flip according to the instructions of the central processing module 11.

[0054] The first wireless data communication unit 18 is used to communicate with the second wireless data communication unit 19 outside the life-saving equipment, and sends the signal sent by the second wireless data communication unit 19 to the central processing module 11. The central processing module 11 is used to wake up the life-saving equipment according to the received signal, or output control information to the motor drive unit 17 according to the received signal. The first wireless data communication unit 18 is also used to send instructions from the central processing module 11 to the second wireless data communication unit 19.

[0055] In combination with the above-mentioned life-saving equipment, the control method of the life-saving equipment provided in the embodiment of the present application is described in detail below.

[0056] Please refer to the attached Figure 2 , a control method for life-saving equipment provided in an embodiment of the present application includes:

[0057] S201: When a driver is driving a lifesaving device, if it is recognized that the driver has left the lifesaving device, a first position of the lifesaving device is determined.

[0058] Specifically, the life-saving equipment has two control modes: local driving and remote control. In the local driving control mode, the driver controls the life-saving equipment by operating the control buttons on the life-saving equipment. In the remote control mode, the rescue personnel control the life-saving equipment through a remote control or other remote terminal, and the remote control or remote terminal and the life-saving equipment can be connected through cloud servers, Bluetooth, WIFI, 5G, etc. The life-saving equipment can switch the current control mode to local driving according to user operations, or it can start the local driving function when it detects that the life-saving equipment has entered the water, or it can start the local driving function when it detects that there is a driver on the life-saving equipment. When the control mode of the life-saving equipment is local driving or remote control, the driver can drive the life-saving equipment.

[0059] When the driver drives the lifesaving device, the lifesaving device starts to identify whether the driver has left the lifesaving device. In one embodiment, when the detection value of the first sensor is within the first numerical range, it is determined that the driver is driving the lifesaving device. If within a preset time period, it is detected that the detection value of the first sensor is within the second numerical range, it is determined that the driver has left the lifesaving device, and the first position of the lifesaving device is determined. Specifically, the lifesaving device obtains the detection value of the first sensor at a set time interval, and when it is detected that the detection value of the first sensor changes from the first numerical range to the second numerical range, and the duration of the detection value in the second numerical range is the preset duration, it is determined that the driver has left the lifesaving device, thereby improving the accuracy of the judgment result and avoiding rescue delays caused by judgment errors.

[0060] In one embodiment, the first sensor is a human body sensor or a pressure sensor.

[0061] Specifically, the human body sensor may be an infrared sensor for detecting human body information. The lifesaving device receives the detection value of the human body sensor, and when it is determined that the detection value is within the first numerical range, it is determined that human body information is detected, and it is determined that there is a driver on the lifesaving device. When it is determined that the detection value is within the second numerical range, and the length of time the detection value is within the second numerical range is a preset time, it is determined that no human body information is detected, and then it is determined that the driver has left the lifesaving device. The pressure sensor may be located above the lifesaving device, and when the driver drives the lifesaving device, the pressure value detected by the pressure sensor is greater than the preset value. The lifesaving device receives the pressure value detected by the pressure sensor, and if the pressure value is greater than the preset value, it is determined that there is a driver on the lifesaving device. If the pressure value is less than the preset value, and the length of time the pressure value is less than the preset value is the preset time, it indicates that the driver has left the lifesaving device.

[0062] When it is determined that the driver has left the lifesaving device, the lifesaving device may determine the first position of the lifesaving device according to the GPS on the lifesaving device, or may determine the first position of the lifesaving device according to image information collected by an image sensor on the lifesaving device.

[0063] S202: Acquire the current location of the lifesaving equipment.

[0064] Specifically, after determining that the driver has left the lifesaving device, the lifesaving device determines the current location of the lifesaving device in real time according to GPS positioning information or image information.

[0065] S203: Controlling the lifesaving device to move to the first position according to the current position of the lifesaving device.

[0066] Specifically, the life-saving device plans a path according to the current position and the first position, and controls the life-saving device to move toward the first position according to the planned path.

[0067] In one embodiment, the life-saving equipment can also determine the obstacle information of the waters where the life-saving equipment is located based on the images captured by the image sensor, and then plan the path based on the obstacle information, the current location of the life-saving equipment and the first location, so that the life-saving equipment can reach the first location as soon as possible.

[0068] In one embodiment, after the life-saving device determines the current position, it determines the first time duration between the current moment and the moment when the life-saving device is located at the first position, determines the environmental information according to the first time duration, and controls the life-saving device to move to the first position according to the environmental information and the current position of the life-saving device. Specifically, the environmental information is the water flow speed or the wind speed. After determining the environmental information, the life-saving device determines the speed required to reach the first position according to the environmental information. For example, if the environmental information is the water flow speed, the speed required to reach the first position is greater than the water flow speed, so the life-saving device is controlled to travel at the corresponding speed. After reaching the first position, the life-saving device instructs the electric drive unit to continue to drive the life-saving device to maintain a speed equal to the water flow speed, so that the life-saving device will not be washed away by the water flow and will continue to be located at the first position.

[0069] In one embodiment, after the lifesaving device moves to the first position, an image captured by an image sensor on the lifesaving device is obtained, the image is recognized, the position of the driver is determined according to the recognition result, the first direction is determined according to the position of the driver, and after the lifesaving device reaches the first position, the lifesaving device is controlled to adjust its direction so that the adjusted direction (orientation) is consistent with the first direction. Wherein, when the orientation of the lifesaving device is the first direction, it is convenient for the driver to grasp the lifesaving device. For example, if the position for grasping on the lifesaving device is located at the head of the lifesaving device, then when the orientation of the lifesaving device is the first direction, the head of the lifesaving device is facing the driver. For another example, if the position for grasping on the lifesaving device is located on the left side of the lifesaving device, then when the orientation of the lifesaving device is the first direction, the left side of the lifesaving device is facing the driver, so that the driver can grasp the lifesaving device as soon as possible, so that the lifesaving device can be driven again.

[0070] In another embodiment, after the lifesaving device moves to the first position, path planning is performed according to the current scene to determine the return path of the lifesaving device at the first position, and then the first direction of the lifesaving device is determined according to the return path. The first direction is the direction in which the lifesaving device can safely travel along the return path. The current scene includes the coast position, the direction of the water flow, the position of obstacles, etc. For example, the first direction is the direction in which the head of the lifesaving device is facing the coast position, or the first direction is the direction in which the driver moves before leaving the lifesaving device, or the first direction is the direction in which the lifesaving device can avoid obstacles during travel. After the lifesaving device reaches the first position, the lifesaving device is controlled to adjust its direction so that the adjusted direction is consistent with the first direction, thereby improving driving safety.

[0071] In another embodiment, the life-saving device may first adjust the direction of the life-saving device to a direction that is convenient for the driver to grasp. When it is determined that the driver is driving the life-saving device, path planning is performed according to the current scene to determine the return path, and the direction of the life-saving device is adjusted to a direction that can be safely driven along the return path.

[0072] In another embodiment, when the lifesaving device recognizes that the driver has left the lifesaving device, the direction of the lifesaving device in the first position is determined, and after controlling the lifesaving device to move to the first position, the lifesaving device is controlled to adjust its direction so that the adjusted direction is consistent with the direction of the lifesaving device in the first position, thereby facilitating the driver to drive the lifesaving device again. The direction of the lifesaving device can be the direction of a preset position of the lifesaving device (e.g., the midpoint of the front end), and the lifesaving device can determine the direction of the lifesaving device in the first position according to a gravity sensor or a posture sensor on the lifesaving device.

[0073] In one embodiment, after the lifesaving device returns to the first position, the image captured by the image sensor is obtained to determine whether there is a human portrait in the image. If there is a human portrait in the image, the lifesaving device is kept at the first position. If there is no human portrait in the image, the lifesaving device can issue an alarm prompt, so that the driver can quickly find the lifesaving device. Alternatively, the lifesaving device can also send information that it is in an unmanned driving state to the server, and the server can send a new control instruction to the lifesaving device according to the rescue needs.

[0074] In one embodiment, if there is a human portrait in the image captured by the image sensor, the life-saving device determines the location of the person based on the image, and then plans a path based on the current location of the life-saving device and the location of the person, and controls the life-saving device to move toward the person according to the planned path, thereby further facilitating the rescue personnel to return to the life-saving device.

[0075] In the above embodiment, when the life-saving device recognizes that the driver has left, it determines the first position of the life-saving device, and controls the life-saving device to move to the first position according to the current position of the life-saving device, thereby preventing the life-saving device from following the water flow and moving to a position far away from the driver, making it convenient for the driver to return to the life-saving device again, thereby ensuring the safety of the personnel.

[0076] In one embodiment, the life-saving device is in a dormant state when not in use. When it is detected that the life-saving device has entered the water, the central processing module of the life-saving device is awakened, and the positioning and orientation unit, the human sensing unit and the motor drive unit of the life-saving device are started at the same time, so that the life-saving device can be quickly started, and then it is detected whether there is a driver driving the life-saving device. When it is detected that the driver has left the life-saving device, the life-saving device is controlled to return to the first position.

[0077] In one embodiment, when it is detected that the life-saving device has entered the water, the posture sensing unit on the life-saving device is simultaneously activated. The life-saving device determines the placement posture of the life-saving device based on the posture information collected by the posture sensing unit. If it is determined that the placement posture of the life-saving device is in an upright state, the life-saving device is controlled to move to a designated position. If it is determined that the placement posture of the life-saving device is in an inverted state, the life-saving device is controlled to flip to an upright state through a motor drive unit. When it is determined that the life-saving device is in an upright state, the life-saving device is controlled to move to a designated position. Specifically, if the placement state of the life-saving device is in an inverted state, the water inlet of the propeller part of the life-saving device faces upward, causing the life-saving device to be unable to travel normally. By flipping the life-saving device to an upright state and then controlling the life-saving device to travel on the water surface, the moving speed of the life-saving device can be increased, thereby saving time during the rescue process and allowing the rescue device to reach the designated position as soon as possible.

[0078] In one embodiment, the lifesaving device determines that the lifesaving device has entered the water when receiving the second information, and the second information is the temperature change information sent by the temperature sensor on the lifesaving device, or the detection distance change information sent by the ultrasonic sensor on the lifesaving device. Specifically, the temperature sensor is located on one side of the lifesaving device, and the temperature in the water is different from the temperature on the shore. When the temperature sensor detects that the temperature change range is greater than a preset value, the temperature change information is sent to the central processing module of the lifesaving device, and the central processing module determines that the lifesaving device has entered the water according to the temperature change information. The propagation speed of ultrasonic waves in water is different from that in air. For objects at the same distance, the distance information detected in water is different from the distance information detected in air. When the ultrasonic sensor detects that the detected distance information has changed, the detection distance change information is sent to the central processing module, and the central processing module determines that the lifesaving device has entered the water according to the distance change information. Alternatively, the ultrasonic sensor determines the propagation time of ultrasonic waves in a specific space. If the propagation time of ultrasonic waves changes, the central processing module determines that the lifesaving device has entered the water according to the change information of the propagation time.

[0079] In one embodiment, the process of activating the life-saving device is as follows: Figure 3 shown.

[0080] When the life-saving device is in a dormant state, it is determined whether the life-saving device has entered the water based on the detection information of the water entry sensing unit, whether the input signal of the local driving unit has changed (for example, the local driving unit has received an instruction from the driver to operate the life-saving device), and whether the wireless data communication unit has received an instruction. If it is determined that the life-saving device has entered the water based on the detection information of the water entry sensing unit, or it is determined that the input signal of the local driving unit has changed, or the wireless data communication unit has received an instruction, the central processing module is awakened, and the life-saving device starts the posture sensing unit, the positioning and orientation unit, the human body sensing unit, and the motor drive unit. After that, the life-saving device executes the process after startup. If it is determined that the life-saving device has not entered the water based on the detection information of the water entry sensing unit, it is determined that the input signal of the local driving unit has not changed, and the wireless data communication unit has not received an instruction, the life-saving device continues to be in a dormant state.

[0081] In one embodiment, the process of flipping the lifesaving device is as follows: Figure 4 shown.

[0082] After the life-saving device is started normally, the water entry sensing unit detects whether the life-saving device has entered the water. If not, the life-saving device enters the standby state and waits for control instructions. If the water entry sensing unit detects that the life-saving device has entered the water, the attitude sensor detects whether the life-saving device is in an inverted state. If it is determined that the life-saving device is in an inverted state, the central processing module controls the motor drive unit to drive the life-saving device to flip to the upright state. If the attitude sensor detects that the life-saving device is not in an inverted state, the life-saving device enters the standby state.

[0083] In one embodiment, the workflow of the lifesaving equipment executing the stay-in-place function is as follows: Figure 5 shown.

[0084] After the life-saving device is started normally, the central processing module receives the control command input by the local driving control unit, and the motor drive unit performs corresponding actions according to the control command. When the human perception unit recognizes that the driver has left the life-saving device, the positioning and orientation unit records the first position of the life-saving device, and then the motor drive unit drives the life-saving device to the first position. If the human perception unit does not recognize that the driver has left the life-saving device, the life-saving device is in normal working state and continues to move according to the control command input by the local driving control unit.

[0085] In the above embodiment, when the life-saving device enters the water, each unit module of the life-saving device is started and enters the local driving state, thereby reducing the time for starting the device and switching modes and improving the rescue efficiency. When the life-saving device is detected to be inverted, the life-saving device is flipped over and then driven, which can increase the driving speed of the life-saving device and avoid the inconvenience caused by artificial flipping of the life-saving device. When the driver leaves the life-saving device, the life-saving device returns to the original place to stay, which can prevent the life-saving device from following the water flow and moving to a position far away from the driver, making it convenient for the driver to return to the life-saving device again, thereby ensuring the safety of the personnel.

[0086] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
