Abstract
Description
Technical Field
[0001] This invention relates to the field of power tool technology, and more specifically, to a power tool and its control method, control device and system, and readable storage medium. Background Technology
[0002] Power tools are mechanized tools powered by an electric motor or electromagnet, which drives the working head through a transmission mechanism. They are typically handheld or portable. Power tools are lightweight and easy to carry and use. Because they can increase productivity several times to dozens of times compared to hand tools, power tools have been widely used in all sectors of the national economy and have also entered household use.
[0003] The problem is that the output mode of many power tools on the market is adjusted mechanically, which makes the adjustment process complicated. Summary of the Invention
[0004] This invention solves the technical problem of complicated output mode adjustment operations in current power tools, and achieves the technical effect of simplifying the adjustment operation and making the operation more convenient and faster.
[0005] To address the aforementioned problems, this invention provides a control method for an electric tool. The electric tool includes a switch module, an interactive control module, a main control center module, and a power output module. The control method includes the following steps: S10: Pressing the switch module to start the electric tool; S20: Touching the interactive control module to issue a switching command, causing the electric tool to switch to a target working mode; S30: The main control center module reads the current switching sequence according to the switching command, obtains the data of the target working mode, and transmits it to the power output module; S40: The main control center module controls the interactive control module to display the target working mode; S50: The power output module performs work according to the data of the target working mode.
[0006] Compared with existing technologies, the technical effects achieved by this solution are as follows: After the user presses the switch module, all modules of the power tool start and begin working under power. The user selects the desired working mode (target working mode) by touching the switch and issues a switching command, realizing human-machine interaction. The main control center module reads the current switching sequence based on the switching command transmitted by the interactive control module, finds the corresponding data of the working mode after the switch, and transmits it to the power output module. The power output module then executes the work according to the corresponding data. The above adjustment method is simple, quick, and easy to operate. Furthermore, the interactive control module displays the current working mode so that the user can control and understand the specific working status of the power tool.
[0007] In one embodiment of the present invention, the host control center module reads the current switching sequence according to the switching instruction to obtain the data of the target working mode, including the following steps: the host control center module parses the switching instruction according to the switching instruction, reads the current switching sequence, and performs a matching degree verification between the current switching sequence and the standard switching sequence; if the verification is successful, the data of the target working mode is obtained; wherein, the matching degree verification includes the following steps: matching the current switching sequence with the standard switching sequence to obtain a first matching degree; if the first matching degree is greater than a first threshold, the verification is successful; if the first matching degree is less than the first threshold, the matching degree verification is repeated; the host control center module stores a standard switching sequence, and each working mode has its own standard switching sequence.
[0008] Compared with existing technologies, the technical effects achieved by this solution are as follows: The host control center module parses the received switching command, obtains and reads the current switching sequence, which is the sequence corresponding to the target working mode. Then, the current switching sequence is compared with the standard switching sequence for matching accuracy. If it matches the standard switching sequence corresponding to the working mode stored in the host control center module, the corresponding working mode data can be obtained with high accuracy. If the matching fails, the matching accuracy verification is repeated to avoid matching errors caused by occasional system problems.
[0009] In one embodiment of the present invention, the control method further includes the following steps: the host control center module determines whether the power output module has achieved the preset working requirements; if the determination is yes, the power output module is controlled to stop performing the work; if the determination is no, the power output module is controlled to continue performing the work until the preset working requirements are achieved.
[0010] Compared with existing technologies, the technical effects achieved by this solution are as follows: the main control center module determines whether the power output module has met the preset working requirements. If the requirements have been met, the module will automatically stop; if the requirements have not been met, the module will continue to work. Users do not need to constantly monitor the working status, making the operation more intelligent and convenient, and saving energy.
[0011] In one embodiment of the present invention, the control method further includes the following steps: the host control center module determines whether the user switches the working mode through the touch interaction control module; if the determination is yes, then step S30 is executed; if the determination is no, then step S40 is executed directly.
[0012] Compared with existing technologies, the technical effects achieved by this solution are as follows: In usage scenarios, users may adjust the working mode in a traditional way. Therefore, the host control center module needs to determine whether the user switches the working mode through the touch interaction control module. If the determination is yes, steps S30, S40, and S50 are executed sequentially; if the determination is no, step S40 is executed directly. At this time, the host control center module can respond promptly to the working mode adjusted by the user, find the corresponding working mode, and control the interaction control module to display the target working mode so that the user can understand the specific working status of the power tool.
[0013] In one embodiment of the present invention, the interactive control module is communicatively connected to the host control center module.
[0014] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the interactive control module transmits various modes to the host control center module in the form of signals, the host control center module responds promptly, and after the working mode is switched, the host control center module can immediately obtain the corresponding data, thereby enabling the power output module to perform operations, making the operation intelligent.
[0015] In one embodiment of the present invention, the interactive control module is provided with multiple working modes, including a low-speed working mode, a normal working mode, and a high-speed working mode. The working efficiency of the power tool in the high-speed working mode is higher than that in the normal working mode, and the working efficiency of the power tool in the normal working mode is higher than that in the low-speed working mode.
[0016] Compared with existing technologies, the technical effects achieved by this solution are as follows: When a user is working with a handheld power tool in normal working mode, fatigue may occur due to prolonged handheld operation. At this time, the user can simply touch the display screen to switch from normal working mode to high-speed working mode to continue operation, shortening the operation time and preventing user fatigue caused by prolonged handheld operation. This solves the problem of user fatigue and prevents user fatigue from endangering personal safety, thus improving the safety of power tool use.

[0026] Figure 2 A flowchart illustrating a power tool control method provided in an embodiment of the present invention. Figure 2 . Detailed Implementation
[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below.
[0028] Example 1:
[0029] See Figure 1This invention provides a control method for an electric tool. The electric tool includes a switch module, an interactive control module, a data processing module, a main control center module, and a power output module. The control method includes the following steps:
[0030] S10: Press the switch module to start the power tool;
[0031] S20: Touch interaction control module, issues switching commands to switch the power tool to the target working mode;
[0032] S30: The main control center module reads the current value switching sequence according to the switching command, obtains the data of the target working mode, and transmits it to the power output module;
[0033] S40: The host control center module controls the interactive control module to display the target working mode;
[0034] S50: The power output module performs its work based on the data of the target operating mode.
[0035] Specifically, after the user presses the switch module, all modules of the power tool start and begin working under power. The interactive control module, for example, can be a display screen showing multiple working modes. The user selects the desired working mode (target mode) by tapping, issuing a switching command to achieve human-machine interaction. For instance, an "OK" interface will pop up on the display screen; after the user selects "OK," the system switches to the target working mode. Alternatively, the user can directly switch to the target working mode after selecting it. After the user selects the target working mode on the interactive control module, the main control center module reads the current switching sequence based on the switching command transmitted by the interactive control module, finds the corresponding data for the working mode after the switch, and transmits it to the power output module. The power output module then executes the work according to the corresponding data. This adjustment method is simple, quick, and easy to operate. Furthermore, the interactive control module displays the current working mode, allowing the user to control and understand the specific working status of the power tool.
[0036] Specifically, the power tool will automatically stop working after the user releases the switch module.
[0037] Specifically, S20 includes the following steps:
[0038] The touch interaction control module acquires the user's touch operation information;
[0039] The touch operation information is parsed to generate switching instructions;
[0040] The handover command is issued through the communication protocol.
[0041] Furthermore, the host control center module reads the current switching sequence according to the switching command to obtain the target working mode data, including the following steps:
[0042] The host control center module parses the switching command according to the switching command, reads the current value switching sequence, and verifies the matching degree between the current value switching sequence and the standard switching sequence.
[0043] If the verification is successful, obtain the data for the target working mode;
[0044] The matching degree verification includes the following steps:
[0045] The current switching sequence is matched with the standard switching sequence to obtain the first matching degree. If the first matching degree is greater than the first threshold, the verification is successful.
[0046] If the first matching degree is less than the first threshold, the matching degree verification is repeated;
[0047] The host control center module stores standard switching sequences, and each working mode has its own standard switching sequence.
[0048] Specifically, the host control center module parses the received switching command, obtains and reads the current switching sequence, which is the sequence corresponding to the target operating mode. Then, it verifies the match between the current switching sequence and the standard switching sequence. If they match the standard switching sequence corresponding to the operating mode stored in the host control center module, the corresponding operating mode data can be obtained with high accuracy. If the match fails, the match verification is repeated to avoid matching errors caused by occasional system problems.
[0049] Specifically, a sequence comparison algorithm is used to calculate the sequence matching score between the current switching sequence and the standard switching sequence to obtain the first matching degree. For example, the first threshold is 95%.
[0050] Furthermore, the control method also includes the following steps: the host control center module determines whether the power output module has achieved the preset working requirements; if the determination is yes, the power output module is controlled to stop performing the work; if the determination is no, the power output module is controlled to continue performing the work until the preset working requirements are achieved.
[0051] Specifically, the main control module determines whether the power output module has met the preset working requirements. If the requirements are met, it automatically stops; if not, it continues to work. This eliminates the need for the user to constantly monitor the working status, making operation more intelligent and convenient, and saving energy. Alternatively, if the requirements are met, it will issue a prompt to the user, who can then choose to stop or switch to another mode to continue working. The prompt can be an audible signal or a visual signal, such as an indicator light on the power tool that illuminates and flashes when the preset working requirements are met.
[0052] Furthermore, the control method also includes the following steps: the host control center module determines whether the user switches the working mode through the touch interaction control module; if the determination is yes, then step S30 is executed; if the determination is no, then step S40 is executed directly.
[0053] Specifically, the above judgment is to determine whether the switching signal meets the switching conditions. If the user switches the working mode through the touch interaction control module, the switching conditions are met; otherwise, the switching conditions are not met.
[0054] Specifically, in certain usage scenarios, users may adjust the working mode using traditional methods. Therefore, the host control center module needs to determine whether the user switches the working mode via the touch interaction control module. If yes, steps S30, S40, and S50 are executed sequentially. If no, the host control center module can identify the user's adjusted working mode and directly execute step S40, skipping steps S20 and S30. In this case, the host control center module can respond promptly to the user's adjusted working mode, find the corresponding working mode, and control the interaction control module to display the target working mode so that the user can understand the specific working status of the power tool.
[0055] Furthermore, the interactive control module communicates with the host control center module.
[0056] Specifically, the interactive control module transmits various modes to the host control center module via signals. The host control center module responds promptly, and after the working mode is switched, it can immediately obtain the corresponding data, thereby enabling the power output module to perform operations, making the operation intelligent.
[0057] Furthermore, the interactive control module is equipped with multiple working modes, including low-speed working mode, normal working mode and high-speed working mode. The working efficiency of the power tool in high-speed working mode is higher than that in normal working mode, and the working efficiency of the power tool in normal working mode is higher than that in low-speed working mode.
[0058] For example, the power output module is a drive motor, whose speed in high-speed operating mode is higher than its speed in normal operating mode, and also higher than its speed in low-speed operating mode. Preferably, the interactive control module is a display screen that enables human-machine interaction, allowing users to select the corresponding operating mode by touching the display screen.
[0059] Specifically, when a user is working with a handheld power tool in normal working mode, they may experience fatigue from prolonged use. In this case, the user can simply tap the display screen to switch from normal working mode to high-speed working mode to continue operating, shortening the operation time and preventing user fatigue from prolonged use of the power tool. This solves the problem of user fatigue and prevents users from endangering their personal safety by working while fatigued, thus improving the safety of using power tools.
[0060] Specifically, the interactive control module has multiple operating modes, each with different operating parameters, including but not limited to: motor speed, motor direction, operating current and voltage.
[0061] Example 2:
[0062] See Figure 2 In one specific embodiment, the interactive control module is a display screen, the host control center module is a controller, the power output module is a motor, and the control method for the power tool includes:
[0063] When the power is turned on, the user operates on the display screen. After the user presses the start switch, the controller is awakened.
[0064] The controller assigns speed and overcurrent protection values based on the current gear and direction, and controls the forward / reverse indicator lights, gear indicator lights, and lighting lights to illuminate.
[0065] The controller determines whether the start switch has been pressed. If it is, it checks whether the controller is malfunctioning. If it is not, the LED turns off, the accumulator increments, and it checks whether to switch gears and directions.
[0066] If the gear and direction are switched, the system will enter sleep mode and the accumulator will be cleared to zero; if the gear and direction are not switched, the LED will turn off and the system will check whether the accumulator has reached the set value.
[0067] If the accumulator reaches the set value, all LEDs turn off; if the accumulator does not reach the set value, the LEDs turn off and the accumulator increments.
[0068] If there are no abnormalities in the controller, assign the forward rotation gear protection parameter and the motor will start.
[0069] After the motor starts, the controller determines whether the current has reached the protection value. If the determination is yes, the motor stops and waits to restart; if the determination is no, it waits until the protection value is reached.
[0070] In case of controller malfunction, check if the start switch is released; if yes, clear the fault state; if no, the LED flashes to indicate the current shutdown state, and displays fault information when a fault occurs.
[0071] After the power switch is released, the power tool enters sleep mode.
[0072] The above gears are motor gears, which are related to the motor speed, and the direction is the direction of motor rotation.
[0073] The power tool provided in this embodiment has LED indicator lights, allowing users to more intuitively understand the operating status of the power tool. In particular, users can operate it directly through the display screen, which is highly intelligent and convenient to use. Moreover, the controller can monitor whether the current reaches the protection value and stop the machine in time to ensure that the power tool is not damaged.
[0074] Example 3:
[0075] Based on Embodiment 1, a sensing module is provided at the handle of the power tool. The control method for the power tool provided by this invention further includes:
[0076] S60: Perform posture recognition on the user's holding state to obtain the posture of the target object, including whether the target object is holding the power tool with both hands, holding the power tool with one hand, or not holding the power tool, including the following steps:
[0077] The sensing module acquires the optical and thermal feature maps of the target object within the handle area, obtains the target object's attitude data based on the optical and thermal feature maps, and feeds it back to the host control center module.
[0078] The host control center module processes the pose data of the target object and inputs it into the network model to obtain the pose of the target object;
[0079] The power tool performs work when the user holds it with one or both hands.
[0080] The power tool automatically shuts off and stops working when the user is not holding it.
[0081] Specifically, the target object mentioned above is the user's hand. A pre-trained network model stores a hand pose dataset and can match it with the pose data to obtain a second matching degree. If the second matching degree is greater than a second threshold, the user's hand pose is obtained. For example, the second matching degree is 90%. By matching the obtained pose data with the dataset in the network model, the pose of the corresponding target object can be quickly obtained with high accuracy. Simultaneously, for user safety, the system can automatically disconnect the power when it detects that the user is not holding the power tool, preventing accidental injury.
[0082] Preferably, the control method further includes performing gesture recognition on the user to obtain the user's identity, which may include children or adults, and includes the following steps:
[0083] The host control center module processes the pose data of the target object to obtain the 3D joint position of the target object and the 3D pose estimation position heatmap of the target object. It then inputs the heatmap into the network model to obtain the user's identity.
[0084] Power tools will not perform work when the user is a child;
[0085] When the user is an adult, the power tools perform the work.
[0086] Specifically, to prevent children from being injured by power tools, the power tools should not be used when children are holding them.
