First, a man-machine interaction control circuit provided in the present application will be described with reference to the accompanying drawings.
Fig. 1 is a schematic diagram of a human-computer interaction control circuit according to a first embodiment of the present application.
As shown in fig. 1, the human-computer interaction control circuit includes an image capturing unit 101, a voice processing unit 102, a video processor 103, and a control unit 104.
A first port of the video processor 103 is connected with the image acquisition unit 101, and is used for identifying an image acquired by the image acquisition unit 101;
a second port of the video processor 103 is connected to the voice processing unit 102, and is configured to perform semantic analysis on the voice acquired by the voice processing unit 102;
the third port of the video processor 103 is connected to the firmware download port of the control unit 104 through the first resistor 105, so as to perform data interaction with the control unit 104 through the firmware download port.
Specifically, the man-machine interaction control circuit provided by the application can be applied to a man-machine interaction system through which a person and a machine interact.
The firmware download port is a port through which the control unit 104 downloads firmware data, and the control unit 104 is connected to a computer device through the firmware download port, for example, after a computer is connected, the firmware data can be downloaded from the computer, so that the firmware data is updated.
The control unit 104, serving as a main control unit of the human-computer interaction system, may be any device capable of implementing a control function, and the specific structure of the control unit 104 is not limited in this application. In this application, the control unit 104, for example, may be an ESP32 WROOM module, which integrates functions such as a bluetooth function, a WiFi function, and a single chip microcomputer, so that the man-machine interaction system does not need to include multiple independent modules, which reduces the area and occupied space of a Printed Circuit Board (PCB) of the man-machine interaction system, and saves the cost.
Since the first resistor 105 is a path resistor, the resistance of the first resistor 105 is smaller than the power-off resistor of the third port of the video processor 103, so that when the human-computer interaction system works normally, the video processor 103 can perform data interaction with the control unit 104 through the firmware download port.
In the application, the video processor 103 is connected with the firmware download port of the control unit 104 through the first resistor 105, so that when the man-machine interaction system works normally, the video processor 103 can perform data interaction with the control unit 104 through the firmware download port, the video processor 103 is powered off, the control unit 104 is connected with a computer device such as a computer through the firmware download port, firmware data can be downloaded from the computer through the firmware download port, so as to update the firmware, thereby realizing multiplexing of the firmware download port of the control unit 104, saving the system port, and providing conditions for system function expansion.
In the present application, the image capturing unit 101 is used for capturing an image, and may be formed by any device having an image capturing function, and the present application does not limit the specific structure of the image capturing unit 101.
The voice processing unit 102 is configured to process the acquired voice, and may be formed by any device having a voice processing function, and the specific structure of the voice processing unit 102 is not limited in this application.
The video processor 103 may be any processor with a multimedia data processing function, and the present application is not limited thereto. In the embodiment of the present application, the video processor may be, for example, an S905X chip, which has a CPU (Central Processing Unit) of a quad-core ARM (Advanced RISC Machine) core-a 53 and a GPU (Graphics Processing Unit) of a Mali-450 of a five-core ARM, and has an excellent audio/video Processing capability, and the chip is used as the video processor, so as to bring an immersive cinema-level entertainment experience to a user. Alternatively, a processing chip such as S912 may be used as the video processor, which is not limited in the present application.
The second port may be a 3.5 mm line in port, or other type of port, which is not limited in this application.
In an exemplary embodiment, the image capturing unit 101 may include a camera module, and the camera module is connected to the first port of the video processor 103 to transmit the captured image to the video processor 103 through the first port, so that the video processor 103 may identify the image captured by the camera module. The voice processing unit 102 may be connected to a microphone array board so that the microphone array board may transmit the picked-up sound to the voice processing unit 102 through a differential signal, and the voice processing unit 102 may transmit the acquired voice to the video processor 103 so that the video processor 103 performs semantic parsing on the voice acquired by the voice processing unit 102. In addition, the voice processing unit 102 may further process the voice signal acquired by the microphone array board, so as to implement functions of waking up words, echo cancellation, noise suppression, reverberation cancellation, and the like.
Therefore, the video processor 103 can realize the functions of image recognition and semantic analysis, and the voice processing, video processing and motion control of the man-machine interaction system are realized by matching the video processor 103 with the control unit 104.
In the man-machine interaction control circuit provided by the application, the video processor 103 is connected with the firmware download port of the control unit 104 through the first resistor 105, so that multiplexing of the firmware download port of the control unit 104 is realized, system ports are saved, and conditions are provided for system function expansion.
It can be understood that the control unit 104 is connected to a computer device such as a computer through a firmware download port, when downloading firmware data, a USB (Universal Serial Bus) port of the computer device such as a computer is usually connected, and communication protocols of the firmware download port and the USB may be different, so in this embodiment of the present application, the USB needs to be converted into a Serial port circuit, and the man-machine interaction control circuit provided in the present application is further described below with reference to fig. 2.
FIG. 2 is a schematic diagram of a human-computer interaction control circuit according to a second embodiment of the present application.
As shown in fig. 2, the human-computer interaction control circuit may further include an interface converter 106 and a second resistor 107.
The interface converter 106 is connected to a firmware download port of the control unit 104 through a second resistor 107; and an interface converter 106 for converting the universal serial bus into a serial circuit.
The interface converter 106 may be any device capable of converting a universal serial bus into a serial circuit, which is not limited in this application. In the embodiment of the present application, the interface converter 106 may be, for example, a CH340G chip or other conversion chip, etc.
By converting the USB into a serial circuit using the interface converter 106, the control unit 104 can download firmware data from a computer device such as a computer through a USB via the firmware update port.
It can be understood that, in general, the serial port of one device can only be externally connected with the serial port of one device, even in case of power failure, the serial port of one device cannot be connected with the serial ports of two devices, because the system is common to ground, the impedance state of the power-off serial port is not determined generally.
In this embodiment, in order to realize multiplexing of the firmware download port of the control unit 104, the resistance of the second resistor 107 may be set to be greater than the resistance of the first resistor 105 and smaller than the power-off resistor of the third port of the video processor 103.
It can be understood that, when the human-computer interaction system is powered on to operate, because the resistance of the first resistor 105 is smaller than the resistance of the second resistor 107, serial data streams can be transmitted between a path with small impedance, that is, the video processor 103 and the control unit 104, so that data interaction between the video processor 103 and the control unit 104 through the firmware download port is realized. When the video processor 103 is powered off and the control unit 104 is connected to a computer device, such as a computer, through the firmware download port, the second resistor 107 and the interface converter 106, the computer device, such as the computer, may supply power to the control unit 104 through the USB interface, and since the resistance of the second resistor 107 is smaller than the power-off resistor of the third port of the video processor 103, serial data stream may be transmitted between the computer device, such as the computer, and the control unit 104, and thus the control unit 104 may download firmware data from the computer device, such as the computer, thereby implementing firmware update.
In an exemplary embodiment, it is assumed that the video processor 103 is an S905X chip, the control unit 104 is an ESP32 chip, the interface converter 106 is a CH340G chip, the power-off resistor at the third port of the S905X chip is more than 200 ohms, the first resistor 105 has a resistance of 22 ohms, and the second resistor 107 has a resistance of 100 ohms. Since the resistance value of the first resistor 105 is smaller than that of the second resistor 107 when the chips S905X and ESP32 work normally, the serial data stream can be transmitted between the chips S905X and ESP32, so that the chips S905X can perform normal data interaction with the chip ESP32 through the firmware download port. When the power is off in S905X, and the ESP32 chip is connected to the computer through the second resistor 107, the CH340G chip, and the USB, and the resistance value of the second resistor 107 is smaller than the power-off resistor at the third port of the S905X chip, the serial data stream may be transmitted between the computer and the ESP32 chip, so that the ESP32 chip downloads firmware data from the computer through the firmware download port to update the firmware.
Therefore, the multiplexing of the firmware download port of the control unit 104 is realized, thereby saving the system port and providing conditions for the system function expansion.

The control unit 104 drives the steering engine assembly 108 to execute operation by using the control signal, so that the steering engine assembly 108 is controlled.
It can be understood that, in practical applications, the steering engine assembly 108 may frequently steer, and in order to avoid interference of a signal generated by the frequent steering of the steering engine assembly 108 on a control signal, in the embodiment of the present application, as shown in fig. 3, the human-computer interaction control circuit may further include an optical coupling isolation unit 109.

The cloud analyzes the acquired data, and after the control instruction is generated, the control instruction can be returned to the control unit 104 in a wireless mode, so that the control unit 104 can control the steering engine component and the like in the machine according to the control instruction.
In an exemplary embodiment, as shown in fig. 3, the human-computer interaction control circuit may further include a remote control assembly 111 wirelessly connected to the control unit 104, and a user may trigger a control instruction by, for example, clicking a button on the remote control assembly 111, so that the remote control assembly 111 may transmit the acquired control instruction to the control unit 104 via a wireless connection to implement control of the machine.
