Description

Technical Field

[0001] The present invention relates to the field of aerospace, and in particular to a fast-moving wearable device for a space station based on gesture control. Background Art

[0002] As my country's manned space program enters the space station operational phase, the complexity of on-orbit scientific research tasks for on-orbit operators has increased significantly, and their operating time has also increased significantly. However, the microgravity environment within the space station makes it difficult for on-orbit operators to move freely like on the ground, making their movements very inconvenient. Currently, intra-cabin mobility mainly relies on a lanyard-assisted device. While this device can basically meet basic mobility needs, it has problems such as cumbersome operation and excessive physical exertion. This not only reduces the operational capacity and efficiency of on-orbit operators, but may also affect their emergency response capabilities in emergency situations. In particular, in the event of emergency events such as depressurization, fire, and power outages that threaten the safety of on-orbit operators, existing lanyard-assisted devices may not provide sufficient flexibility and speed, making it difficult for on-orbit operators to respond immediately. Therefore, there is an urgent need to develop a simple-to-operate in-cabin wearable device to effectively improve the efficiency and flexibility of on-orbit operators in the space station and provide strong support for on-orbit operational tasks and emergency and fault handling. Summary of the Invention

[0003] The present invention provides a wearable device for rapid movement in a space station based on gesture control, aiming to solve the problem of inconvenience in movement for on-orbit operators in the microgravity environment of the space station. By combining gesture recognition with mechanical transmission, efficient and flexible movement within the cabin is achieved.

[0004] In order to solve the problem of inconvenience in the cabin movement of on-orbit operators in the aerospace field, the technical solution of the present invention is: a space station mobile wearable device based on gesture control, including: a launching device, a somatosensory recognition module and a control module.

[0005] Furthermore, the launch device includes: an upper shell equipped with an adsorption component, the front end of the adsorption component is equipped with an N45 circular magnet, the rear end is connected to a lightweight nylon line, the adsorption component is also covered with a spring, the upper shell is connected to the lower shell by a thread, a push-pull electromagnet is fixed to the lower shell, and a stopper (108) is fixed to the push-pull electromagnet for clamping or releasing the adsorption component. The lightweight nylon line is wound on a bobbin, and the bobbin is placed on the lower shell. The transmission shaft is simultaneously keyed to the bobbin and the worm gear. The worm drives the worm gear. The cover plate is threadedly fixed to the lower shell. The display screen is embedded and buckled on the upper shell. The display screen uses a low-power OLED screen to display the remaining power and moving speed in real time. The lower shell is also fixed with a strap, and the strap is buckled to tie the launch device to the arm of the on-orbit operator.

[0006] Furthermore, the somatosensory recognition module is integrated into the lower shell, and includes a Cortex M4 processor, a three-axis gyroscope, a three-axis accelerometer, a three-axis magnetometer, and a medical-grade stainless steel electromyography sensor. The somatosensory recognition module recognizes the gestures of the on-orbit operator (such as clenching a fist, opening a fist, etc.) through multi-sensor data fusion. The lithium-ion battery A powers the module, the Bluetooth module realizes wireless data transmission, and the USB interface A charges the lithium-ion battery A. The ultrasonic sensor monitors the movement speed of the on-orbit operator in real time, provides speed and torque feedback adjustment for the brushless motor, and ensures the smoothness of the movement process. The inductive proximity switch can send a signal to the controller when the adsorption component is recovered, and the controller controls the brushless motor to stop working.

[0007] Furthermore, the control module receives gesture data from the motion recognition module. After processing by the controller, it controls the opening and closing of the push-pull electromagnet circuit via a relay, achieving the ejection and release of the adsorption component. Simultaneously, the controller adjusts the speed and torque of the brushless motor through the motor driver, driving the worm gear mechanism to retract and release the nylon line, driving the on-orbit operator to move rapidly along the cabin wall. Lithium-ion battery B powers the module, and USB port B charges lithium-ion battery B.

[0008] Compared with the prior art, the gesture-controlled wearable device for rapid movement of a space station of the present invention has the following advantages:

[0009] The control method based on gesture recognition does not require complex mechanical operations. On-orbit operators can achieve movement through simple gestures (such as clenching the fist to launch and opening the fist to recover), which improves the efficiency and convenience of on-orbit operators' on-orbit operations.

[0010] The brushless motor in the control module is combined with an ultrasonic sensor for speed feedback adjustment, ensuring the stability and accuracy of the motor operation, allowing on-orbit operators to move smoothly and quickly within the space station.

[0011] The lightweight structure and arm strap design are adapted to the operational needs of on-orbit operators. The display screen shows the device status in real time, supports rapid access to information, and meets the mobility needs of on-orbit missions and emergency scenarios.

[0016] Example 1: Referring to the accompanying drawings, a space station fast-moving wearable device based on gesture control is characterized by comprising: a transmitting device (1), a body sensing recognition module (2) and a control module (3).

[0017] like Figure 1 Figure 2 The launching device (1) comprises: an upper shell (102) equipped with an adsorption component (101); an N45 circular magnet (103) is installed at the front end of the adsorption component, and a light nylon line (104) is connected to the rear end; the adsorption component is also covered with a spring (105); the upper shell (102) is connected to the lower shell (106) by a thread; a push-pull electromagnet (107) is fixed to the lower shell (106); a stopper (108) is fixed to the push-pull electromagnet for clamping or releasing the adsorption component. The light nylon line (104) is wound on a bobbin (109), and the bobbin (109) is placed on the lower shell (106). A transmission shaft (110) is simultaneously keyed to the bobbin (109) and a worm gear (111). A worm (112) drives the worm gear (111). A cover plate (113) is threadedly fixed to the lower shell (106). A display screen (114) is embedded and buckled on the upper housing (102). The display screen (114) uses a low-power OLED screen to display the remaining power and moving speed in real time. The lower housing (106) is also fixedly connected to a strap (115). The strap (115) is used to buckle the launch device (1) to the arm of the on-orbit operator.

[0018] like Figure 3The body-sensing recognition module (2) includes: a Cortex M4 processor (201), a three-axis gyroscope (202), a three-axis acceleration sensor (203), a three-axis magnetometer (204), a medical-grade stainless steel electromyography sensor (205), a lithium-ion battery (206), a Bluetooth module (207) for transmitting data, and an ultrasonic sensor (208) for real-time monitoring of the speed of the on-track operator and performing speed and torque feedback regulation on the brushless motor (304), and a USB interface A (209) for charging the lithium-ion battery A (206). The body-sensing recognition module (2) is fixedly connected to the lower housing (106) and recognizes gestures through fusion data of the gyroscope (202), the acceleration sensor (203), the magnetometer (204) and the electromyography sensor (205).

[0019] The control module (3) includes: the body sensing recognition module (2) sends gesture data to the controller (301), the controller (301) sends an electrical signal to the relay (302), and the relay (302) controls the push-pull electromagnet (107) by opening and closing the circuit. The controller (301) is connected to the motor driver (303) through an interface, and the motor driver (303) controls the speed and torque of the brushless motor (304), and the brushless motor (304) drives the worm (112). There is also a lithium-ion battery B (305) for powering the control module (3) and a USB interface B (306) for charging the lithium-ion battery B (305). The inductive proximity switch (307) can send a signal to the controller (301) when the adsorption component (101) is recovered, and the controller (301) controls the brushless motor (304) to stop working.

[0020] The gestures include but are not limited to clenching a fist, opening it, and double-clicking.

[0021] During the launch, the gesture is a fist-clenching gesture. The body sensing recognition module (2) collects the gesture data and sends it to the controller (301) via the Bluetooth module (208). The controller (301) processes the data and sends an electrical signal to the relay (302). The relay (302) closes the circuit, the controlled circuit is connected, and the push rod inside the corresponding push-pull electromagnet (107) moves forward with a certain stroke, pulling the block (108) open. The adsorption component (101) is released and ejected by the elastic force of the spring (105).

[0022] During recovery, the gesture is to open the palm of the hand. The body sensing recognition module (2) collects the gesture data and sends it to the controller (301) via the Bluetooth module (208). The controller (301) processes the data and sends an electrical signal to the motor driver (303). The motor driver (303) controls the brushless motor (304) to rotate. The brushless motor (304) drives the worm (112). The worm (112) drives the worm gear (111). The worm gear (111) drives the bobbin (109) to recover the lightweight nylon line (104). Since the cabin is in a microgravity environment, the launch device (1) drives the on-orbit operator to move along the lightweight nylon line (104). When the speed of the on-track operator exceeds 1.5 m / s, the ultrasonic sensor sends a signal to the controller (301). The controller (301) processes the data and sends an electrical signal to the motor driver (303). The motor driver (303) increases the speed and torque of the brushless motor (304) so that the lightweight wire pulls the magnet to detach from the bulkhead. At this time, the on-track operator moves forward at a constant speed due to inertia. After the lightweight nylon wire (104) is recovered, the inductive proximity switch (307) sends a signal to the controller (301). The controller (301) controls the brushless motor (304) to stop working, and the recovery process ends. After the on-track operator reaches the destination, he can press the adsorption component (101) into the upper shell (102). The spring (105) is compressed to prepare for the next use.

[0023] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
