[0075] The MCU obtains instructions through communication with the host computer's USB interface via ch340n. The IO ports P14 / 15 / 54 / 55 control the output ports through MOS transistors U5 to U8. Each output has an independent working indicator light L4 to L7, and the output is stabilized in the off state through pull-up resistors.

[0078] For the USB-to-serial port part, one indicator light each for transmission and reception shows the communication status, and D1 and R3 prevent current backflow when the USB is powered off.

[0079] The AD detection circuit consists of an NTC thermistor and a pressure sensor. The pressure sensor uses a separate zener diode ZD1 to stabilize the working voltage to ensure accuracy. The temperature data and pressure data are sent to the MCU by P10 and P11.

[0080] Two additional signal input / output interfaces with 5V power supply and one controllable output port are reserved.

[0081] Device function description:

[0101] Lower computer: Extract the data in the receive buffer, start parsing the communication protocol, and compare key protocol elements such as the packet header, checksum, and data length of the received data.

[0102] Judgment result - conforms to the protocol: If the parsed data completely matches the requirements of the communication protocol, enter the next step to execute the instruction action.

[0103] Judgment result - does not conform to the protocol: If there is any discrepancy between the data and the communication protocol, discard the current data, return to the state of listening to the communication port, and feedback the receive error information to the host computer.

[0104] Execute the instruction action:

[0105] Lower computer: According to the parsed instruction content, call the corresponding function module to execute the action. For example, if it is an instruction to control the motor vibration, adjust the parameters of the motor drive module.

[0106] Lower computer: Package the feedback information according to the communication protocol and send it back to the host computer through the communication link.

[0107] End:

A tactile interaction method for an intelligent vending machine, characterized in that: Applied to the tactile interaction device of any one of claims 1 to 5, the method comprises: The user clicks on the smart vending machine screen to start the interactive game; The vending machine main control system sends a start command to the tactile interaction device; The holding part of the tactile interaction device reminds the user to pick up the holding part through the vibration module; The user operates the grip component, and the gyroscope sensor and air pressure sensor in the grip component collect the user's hand movement data in real time, including squeezing force, force application speed, azimuth angle and acceleration, and transmit the data to the main control component; The main control component receives sensor data and processes the data according to preset logic to generate control instructions; The main control component controls the inflation module, pressure relief module and vibration module through the gas-electric hybrid pipeline to provide tactile feedback to the user; According to the completion of the user's operation, the vending machine main control system controls the delivery device to output rewards.

7. The tactile interaction method for a smart vending machine according to claim 6, characterized in that: The tactile feedback includes: Pumping gas into the air pressure container of the gripping component through the inflation module to expand the gripping component and increase its hardness; The gas in the air pressure container is released through the pressure relief module to soften the gripping part; Vibration feedback of different frequencies is output through the vibration module.

8. The tactile interaction method for a smart vending machine according to claim 6, characterized in that: The gripping component is detachable and is mounted on the bottom plate of the device by magnetic attraction or mechanical fixation, so that the shape of the gripping component can be quickly changed according to different scenarios.

9. The tactile interaction method for an intelligent vending machine according to claim 6, characterized in that: The communication process between the main control component and the vending machine main control system: The main control component establishes a connection with the main control system of the vending machine through a communication interface; The vending machine main control system encapsulates the instruction according to the preset communication protocol and sends it to the main control component through the communication interface; The main control component receives the command and parses it. If the command meets the protocol requirements, it executes the corresponding control action and encapsulates the feedback information and transmits it back to the vending machine main control system through the communication interface; If the instruction does not meet the protocol requirements, the main control component discards the instruction and feeds back an error message to the vending machine main control system.

10. The tactile interaction method of the intelligent vending machine according to claim 6, characterized in that: The method also includes a communication process between the tactile interaction device and the host computer, which specifically includes: The main control component of the tactile interaction device establishes a connection with the host computer via a communication interface; The host computer encapsulates the instructions according to the preset communication protocol and sends them to the main control component through the communication interface; The main control component receives and analyzes the command. If the command meets the protocol requirements, it executes the corresponding control action and encapsulates the feedback information and transmits it back to the host computer through the communication interface; If the instruction does not meet the protocol requirements, the main control component discards the instruction and uploads an error message to the host computer.
