With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0029] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.
[0030] This embodiment discloses a somatosensory device control system, such as Figure 1 As shown, it includes: a main control module 1, a motor driving module 2, an electric stimulation driving module 4, a somatosensory suit, a motor 3 and an electrode strap 5 arranged on the somatosensory suit.
[0031] In this embodiment, the somatosensory suit is in the form of a vest, on which forty motors 3 are evenly arranged.
[0032] The main control module 1 and the motor drive module 2 are both arranged on the somatosensory suit. The main control module 1 is connected to the motor drive module 2 by wire, and the motor drive module 2 is electrically connected to the motor 3 .
[0033] Since the main control module 1 needs to process and forward data, the control chip model selected in this embodiment is STM32F103CBT6, and multiple filter capacitors are mounted externally to ensure the chip works stably. Figure 2 shown.
[0034] Since the main control module 1 needs to communicate with the host computer 6 to receive the somatosensory data from the host computer 6, for the convenience of use, in this example, it is preferably set that the main control module 1 communicates with the host computer 6 through wireless communication, specifically through a Bluetooth communication module, the model of which is RF-BM-BG22 module. This module uses Bluetooth 5.0 or above protocol and can forward the received data to the main control module 1 through the serial port, such as Figure 3 shown.
[0035] The motor drive module 2 is used to control the motor 3 to work according to the motor control data. The motor drive module 2 includes a protocol conversion chip and a motor drive switch circuit. The model of the protocol conversion chip is PCA9685 or PCA9635, and the external resistor is configured for the I2C address. The 10-way PWM output is controlled by I2C to control the action of the motor 3 separately. Figure 4The motor drive switch circuit controls the motor 3 on and off through the PWM signal to realize the amplification function of the drive current, such as Figure 5 shown.
[0036] The main control module 1 is wirelessly connected to the electrical stimulation driving module 4 , and the electrical stimulation driving module 4 is electrically connected to the electrodes on the electrode band 5 .
[0037] The electrical stimulation drive module 4 is used to generate the charge and discharge signals of the positive and negative electrodes on the electrode band 5 according to the electrical stimulation control data. The control chip model of the electrical stimulation drive module 4 adopts the STC8H8K64U series single-chip microcomputer, and the voltage pin is externally connected with a capacitor for filtering to ensure that the chip works normally. Figure 6 shown.
[0038] In order to realize electrical stimulation, the electrical stimulation driving module 4 includes, in addition to the control chip, an electrical stimulation signal boost excitation-release circuit for realizing electrical stimulation. The electrical stimulation signal boost excitation-release circuit is composed of a BOOST boost part and an energy storage release part. The control chip controls the Q3 transistor to be continuously turned on and off, and continuously charges the C6 capacitor. After charging, the discharge is controlled through the Q2 transistor, such as Figure 7 shown.
[0039] Since the main control module 1 is connected to a Bluetooth communication module for wireless communication, in order to facilitate the wireless connection between the main control module 1 and the electric stimulation driving module 4, this embodiment also includes connecting a Bluetooth communication module to the electric stimulation driving module 4 to achieve wireless connection between the main control module 1 and the electric stimulation driving module 4 via Bluetooth. In this embodiment, the model of the Bluetooth communication module connected to the electric stimulation driving module 4 is set to be E104-BT08, which uses the BT5.1 protocol for data exchange and can forward the received data through the serial port, such as Figure 8 shown.
