Title of Work: Intelligent RV Control System Introduction of Work:

The home facilities on the RV include: lighting, sofas, seats, air conditioners, TVs, stereos and other electrical appliances. It is inconvenient to set independent switches for each appliance. The intelligent RV control system solves this problem. The deep learning speech recognition technology of artificial intelligence technology achieved a breakthrough in 2013. After the technological breakthrough, the voice interaction method will occupy an important position for a long time. Large-size touch screens are also the development trend of vehicle-mounted human-computer interaction equipment in recent years. This system uses voice recognition and display human-machine interface (HMI) as human-machine interaction equipment, and users can control electrical appliances through voice and touch screen.

System block diagram:

System introduction: 1. GD32E231 is used as the control unit; 2. Serial port screen and SYN7318 voice recognition and playback module are used as human-machine interaction equipment; 3. Relays and infrared transmitting tubes are used to control simple electrical appliances and household appliances. 1. HMI Function Description Analysis When the user touches the icon, the HMI sends the icon corresponding to the ID through the serial port, and the MCU parses the ID to drive the relay and infrared transmitting tube. The software framework and file call relationship are as follows: 414706 414707 2. Analysis of voice recognition and playback functions SYN7318 module integrates voice recognition, voice synthesis and voice wake-up functions. In terms of voice recognition, it supports voice recognition of 10000 words and can realize semantic understanding. The voice recognition word library needs to be downloaded by the user. Voice playback supports voice synthesis playback, built-in MP3 playback and external MP3 playback. The software framework consists of command parsing, status judgment, voice playback, and voice recognition command execution. The relationship between the software framework and file calls is shown in the figure below:

3、Analysis of infrared sending function Use analyzer/oscilloscope to capture infrared waveform and determine the infrared encoding type.

(MATSUSH encoding)

Generally, infrared encoding is divided into starting signal, logic level0, logic level1.If you can capture these three signals and implement them, the entire infrared encoding sending problem will be solved. The relationship between the software framework and file calls is as follows:

It is recommended to open it with SourceInsight, Keil code format looks messy. SourceInsightConfig_190522.CF3 (130.13 KB, downloads: 12)

Very good, I will download it and learn from it when I have free time.

I just checked online, this speech recognition + synthesis module is not cheap, but its functions are very powerful.

It still looks very technological to the layman

SYN7318 response statement implementation method: prepare N kinds of response statements in advance, and use random numbers to select the response statement when answering. This has achieved wake-up and recognition of error voice prompts, making the response less boring and monotonous, and increasing the fun.
