[0026] Figure 1 A schematic diagram of the structure of a remote control device provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the remote control device comprises:

[0027] The hand-crank control module 100 includes a hand-crank drive mechanism 11 and a posture sensor 12; the hand-crank drive mechanism 11 is designed to receive a user's rotation operation, and drive the internal shaft 13 to rotate through the operation; the posture sensor 12 is used to detect the rotation direction and rotation speed of the shaft 13;

[0028] The switch screwing module 200 is used to drive the mechanism operating hole 21 to rotate in the corresponding rotation direction and rotation speed according to the rotation direction and rotation speed of the rotating shaft 13 provided by the posture sensor 12.

[0029] Among them, the hand-cranked control module 100 can be understood as a control end, and the switch turning module 200 can be understood as an operating end, which should at least include a numerical control motor 24 that can be driven according to a rotation signal.

[0030] Specifically, when the user drives the hand-cranked driving mechanism 11 to rotate, the internal shaft 13 will rotate according to the direction and speed of the user driving the hand-cranked driving mechanism 11. At this time, the posture sensor 12 will capture the rotation state of the shaft 13 in real time and convert it into a corresponding electrical signal. The above electrical signal records the rotation direction and speed information of the shaft 13 and is transmitted to the switch screwing module 200. After successfully receiving the above electrical signal, the switch screwing module 200 controls the CNC motor 24 to rotate the mechanism operating hole 21 according to the specified rotation direction and speed.

[0031] The technical solution of the embodiment of the present invention provides a remote control device, in which the user inputs rotation information by rotating the hand-cranked drive mechanism on the hand-cranked control module, and transmits the rotation information to the switch turning module in the form of an electrical signal. The switch turning module simulates the rotation operation to achieve precise control of remote devices (such as rotary switches, valves, etc.).

[0032] Optionally, the hand-cranked driving mechanism 11 includes a hand-cranked handle 111 and a transmission structure 112, and the hand-cranked handle 111 is connected to the rotating shaft 13 through the transmission structure 112 to drive the rotating shaft 13 to rotate according to the user's rotation operation.

[0033] Among them, the hand crank handle 111 can be understood as the part of the hand crank drive mechanism 11 that the user directly contacts and rotates, allowing the user to apply rotational force; the transmission structure 112 can be understood as being used to transmit the rotational motion of the hand crank handle 111 to the rotating shaft 13 or other parts that need to be driven. Exemplarily, the transmission structure 112 may include gears, belts, chains, connecting rods, etc.

[0034] Specifically, the user holds the hand crank to rotate it clockwise or counterclockwise, and the transmission structure 112 transmits the rotational force of the hand crank 111 to the rotating shaft 13, and also changes the input speed, torque and even rotation direction through the transmission structure 112, so as to meet the different needs of the user. For example, a multi-gear set is used as the transmission structure 112, and the multi-gear set can achieve the increase and decrease of the speed, the change of the torque and the change of the rotation direction by matching gears with different numbers of teeth.

[0035] Optionally, the transmission structure 112 includes a first gear 1121 and a second gear 1122; the central axis of the first gear 1121 is fixedly connected to the hand crank 111, the first gear 1121 and the second gear 1122 are meshed, and the central axis of the second gear 1122 is fixedly connected to the rotating shaft 13.

[0036] The first gear 1121 may be understood as an input portion of the transmission structure 112 having a gear structure, and the second gear 1122 may be understood as an output portion of the transmission structure 112 having a gear structure.

[0037] Specifically, when the hand crank 111 drives the small gear to drive the large gear, that is, the first gear 1121 is a small gear and the second gear 1122 is a large gear, the rotating shaft 13 rotates at a slower speed than the central axis of the hand crank, but generates a greater torque. On the contrary, if the large gear drives the small gear, that is, the first gear 1121 is a large gear and the second gear 1122 is a small gear, then the rotating shaft 13 will increase in speed, but the torque will decrease. In addition, the gear set can also achieve a change in the direction of rotation.

[0038] Optionally, the switch screwing module 200 includes a screwing programmable logic controller 22, a servo controller 23, a CNC motor 24 and a transmission shaft 25; the screwing programmable logic controller 22 is electrically connected to the servo controller 23, the servo controller 23 is electrically connected to the CNC motor 24, and the transmission shaft 25 is connected to the CNC motor 24 through a buckle; the screwing programmable logic controller 22 is used to process the rotation direction and speed of the rotating shaft 13 provided by the posture sensor 12, and generate screwing speed and angle instructions; the servo controller 23 is used to control the CNC motor 24 according to the screwing speed and angle instructions, and the driving mechanism operating hole 21 rotates according to the corresponding rotation direction and rotation speed. Among them, the screwing programmable logic controller 22 can be understood as a device for receiving, storing, executing and monitoring instructions from various input devices, and controlling the operation of the screwing module 200 according to these instructions. In the remote control device, the screwing programmable logic controller 22 is the core component of the switch screwing module 200, which is responsible for processing the rotation information of the shaft 13 provided by the posture sensor 12 and generating corresponding control instructions; the servo controller 23 can be understood as a motor controller, which accurately controls the speed, position and torque of the motor according to the received instruction signal. In the remote control device, the servo controller 23 receives the screwing speed and angle instructions from the screwing programmable logic controller 22, and ensures that the CNC motor 24 realizes accurate and stable rotation operation according to the instruction requirements according to the above instructions.

[0039] Specifically, when the screwing programmable logic controller 22 receives the signal sent by the hand-cranked programmable logic controller 15, the screwing programmable logic controller 22 parses the rotation direction and speed information in the electrical signal, and then generates a screwing speed and angle instruction for sending to the servo controller 23 according to the preset control logic. When the servo controller 23 receives the above-mentioned screwing speed and angle instruction, the servo controller 23 drives the CNC motor 24 to start and rotate according to the instruction. The CNC motor 24 is connected to the mechanism operating hole 21 through the transmission shaft 25 to ensure that the rotational force can be directly transmitted to the operating hole, and finally realize the precise control of the remote device. In the whole process, the screwing programmable logic controller 22, the servo controller 23 and the CNC motor 24 work together to form an efficient and stable control system, ensuring the accuracy and reliability of the remote control operation.

[0040] Optionally, the switch turning module 200 also includes a dynamic torque sensor 25, which is used to collect the dynamic torque and speed of the transmission shaft 25; the hand-cranked control module 100 also includes a resistance module 14 and a hand-cranked programmable logic controller 15; the hand-cranked programmable logic controller 15 includes a normal working mode; the hand-cranked programmable logic controller 15 is electrically connected to the resistance module 14, and is used to control the resistance module 14 to apply a simulated resistance that is positively correlated with the dynamic torque and speed signals to the rotating shaft 13 according to the dynamic torque and speed signals collected by the dynamic torque sensor 25 in the normal working mode.

[0041] Among them, dynamic torque can be understood as a physical quantity with clear directionality, which reflects the magnitude and direction of the torque received by the object during the rotation process. The dynamic torque sensor 25 is a precision measuring instrument for measuring various torques, speeds and mechanical powers. In the embodiment of the present invention, a non-contact dynamic torque sensor 25 is preferably used, which adopts the principles of electrical, magnetic and optical induction to obtain measurement information, and can obtain accurate measurement information without direct contact with the measured object, thereby effectively avoiding the error and wear problems caused by contact friction. In addition, in order to more realistically simulate the force conditions during the screwing process, the embodiment of the present invention sets a resistance module 14 in the hand-cranked control module 100, and the resistance module 14 can be understood as a structure that can generate a simulated resistance corresponding to the resistance received during the simulated screwing process according to actual needs; the hand-cranked programmable logic controller 15 is used to receive the dynamic torque and speed information obtained by the dynamic torque sensor 25, and generate corresponding control signals based on the above information to control the resistance module 14 to generate a simulated resistance that is positively correlated with the dynamic torque and speed signals. It should be noted that the normal working mode refers to the working state when the device is in a normal operating state.

[0042] Specifically, under normal working conditions, the hand-cranked programmable logic controller 15 dynamically adjusts the simulated resistance applied by the resistance module 14 based on the dynamic torque and speed signals collected in real time by the dynamic torque sensor 25, ensuring that the user can feel the resistance changes consistent with the actual twisting process of the remote device when twisting the hand-cranked handle 111, thereby improving the accuracy and realism of the remote control operation.

[0043] Optionally, the hand-cranked programmable logic controller 15 also includes an initial working mode. The hand-cranked programmable logic controller 15 switches from the initial working mode to the normal working mode when the dynamic torque and speed signals provided by the dynamic torque sensor 25 are received instead of being received. The hand-cranked programmable logic controller 15 is used to control the resistance module 14 to apply the maximum simulated resistance to the rotating shaft 13 in the initial working mode.

[0044] Among them, the initial working mode can be understood as a special working state, which is designed to provide the user with a larger resistance feedback when no dynamic torque and speed signals are received.

[0045] Specifically, when the remote control device is powered on but not running or idle, the switch system remains stationary, and the dynamic torque sensor 25 has not yet detected the dynamic torque and speed signals. If the user tries to turn the hand crank 111 at this moment, since the dynamic torque sensor 25 has not yet detected the dynamic torque and speed signals, the resistance module 14 has not generated simulated resistance, and the user will not be able to obtain real operational resistance feedback. In order to solve the above problem, the embodiment of the present invention introduces an initial working mode. When the hand-cranked programmable logic controller 15 does not receive the dynamic torque and speed signals provided by the dynamic torque sensor 25, the resistance module 14 will apply the maximum simulated resistance to the rotating shaft 13. When the dynamic torque sensor 25 detects that the transmission shaft 25 starts to rotate and transmits the dynamic torque and speed signals to the hand-cranked programmable logic controller 15, the hand-cranked programmable logic controller 15 seamlessly switches the working mode of the device from the initial working mode to the normal working mode. At this time, the hand-cranked programmable logic controller 15 generates a control signal corresponding to the dynamic torque and speed signal and transmits it to the resistance module 14. The resistance module 14 dynamically adjusts the size of the applied simulated resistance to ensure that the user can feel the resistance change consistent with the actual twisting process of the remote device when twisting the hand-cranked handle 111, thereby improving the accuracy and realism of the remote control operation.

[0046] It should be noted that the logical condition for the device to enter the initial working mode is not limited to the device being powered on but not receiving an input signal. In some cases, such as when the dynamic torque sensor 25 fails to transmit the dynamic torque and speed signal to the hand-cranked programmable logic controller 15 within a certain response time, the hand-cranked programmable logic controller 15 will also trigger the initial working mode to ensure the stability of the device and the safety of user operation.

[0047] Optionally, the resistance module 14 includes: a brake shaft 141 and at least two electromagnetic resistance contacts 142 arranged on the hand-cranked control module 100; the brake shaft 141 is transmission-connected to the rotating shaft 13; the hand-cranked programmable logic controller 15 is used to control the opening of a number of electromagnetic resistance contacts 142 that are positively correlated with the dynamic torque and speed signals collected by the dynamic torque sensor 25, so as to apply friction force to the brake shaft 141, thereby forming a simulated resistance applied to the rotating shaft 13 that is positively correlated with the dynamic torque and speed signals.

[0048] The resistance module may be understood as a device that provides corresponding resistance feedback according to an input signal. In the embodiment of the present invention, the resistance module is an electromagnetic resistance module, and each electromagnetic resistance contact provides friction force of the same magnitude.

[0049] Specifically, when the CNC motor 24 drives the mechanism operating hole 21 to rotate in the specified direction and speed, the dynamic torque sensor 25 obtains the dynamic torque and speed signal of the transmission shaft 25 and transmits it to the hand-cranked programmable logic controller 15. The hand-cranked programmable logic controller 15 calculates the resistance that the resistance module 14 should apply to the rotating shaft 13 based on the dynamic torque and speed signals, and controls the corresponding number of electromagnetic resistance contacts 142 to open. For example, when the dynamic torque increases, the hand-cranked programmable logic controller 15 will control the resistance module 14 to open more electromagnetic resistance contacts 142, so that the friction on the brake shaft 141 increases, thereby applying a greater simulated resistance on the rotating shaft 13.

[0050] Optionally, the switch screwing module 200 further includes an operating tool, which is assembled on the transmission shaft 25 , and the operating tool is detachable and adapted to the mechanism operating hole 21 .

[0051] The operating tool may be understood as one or more modular components (such as replaceable heads or accessories), the shapes, sizes and materials of which ensure that they can fit tightly with different types of operating holes.

[0052] Specifically, before using the switch screwing module 200 for operation, the operator needs to select an appropriate operating tool according to the type and size of the operating hole and install it on the transmission shaft 25. Exemplarily, the mechanism operating hole 21 can be a raised hexagonal shape, and the corresponding operating tool is a hexagonal sleeve.

[0053] Optionally, the hand-cranked control module 100 also includes a hand-cranked wireless transmission module 16; the switch turning module 200 also includes a turning wireless transmission module 27; the switch turning module 200 and the hand-cranked control module 100 communicate through the turning wireless transmission module 27 and the hand-cranked wireless transmission module 16 to achieve remote control.

[0054] The hand-crank wireless transmission module 16 can be understood as a wireless transmission module provided on the hand-crank control module 100, and the screw wireless transmission module 27 can be understood as a wireless transmission module provided on the switch screwing module 200. For example, the wireless communication module can be a Bluetooth module or a WIFI module.

[0055] Specifically, the hand-cranked wireless transmission module 16 is integrated in the hand-cranked control module 100, and the module is electrically connected to the hand-cranked programmable logic controller 15. The switch screwing module 200 is integrated with the screwing wireless transmission module 27, and the module is electrically connected to the screwing programmable logic controller 22. The hand-cranked wireless transmission module 16 is configured to receive a wireless signal from the switch screwing module 200. The screwing wireless transmission module 27 is configured to receive a wireless signal from the hand-cranked control module 100.

[0056] Figure 2 A schematic diagram of another remote control device provided by an embodiment of the present invention, referring to Figure 2 In an optional embodiment, the hand-cranked control module 100 also includes a visualization module 17, which is electrically connected to the hand-cranked programmable logic controller 15; the hand-cranked programmable logic controller 15 is also used to obtain the dynamic torque and speed signals of the transmission shaft 25 through the dynamic torque sensor 25; the visualization module 17 is used to display the dynamic torque and speed signals of the transmission shaft 25 in real time.

[0057] Specifically, a visualization module 17 is provided on the hand-cranked control module 100 for displaying in real time the dynamic torque and speed signals of the transmission shaft 25 obtained by the dynamic torque sensor 25. Through the real-time display function of the visualization module 17, the user can intuitively understand the rotation state of the transmission shaft 25, thereby more accurately controlling the mechanism operating hole 21, ensuring the accuracy and safety of the operation.

[0058] Exemplarily, the visualization module 17 includes a rotation angle indicator plate and a rotation speed display. The rotation angle indicator plate is used to display the actual rotation angle and rotation direction of the mechanism operating hole 21, and the rotation speed display displays the rotation speed of the mechanism operating hole.
