[0002] With the continuous development of society and the continuous improvement of people's living standards, cars are becoming more and more popular as a means of transportation in people's lives. In the automotive industry, people have higher and higher requirements for the safety, functionality and comfort of cars, and therefore pay more and more attention to the experience during the ride. As one of the decorative lighting tools in the car, the atmosphere light makes the cabin more gorgeous, increases the user's driving pleasure, and creates a warm atmosphere in the car. At present, vehicle voice control is mainly focused on the realization of in-vehicle navigation, automatic cruise, and air conditioning functions, and there has been no significant progress in voice control atmosphere lighting technology.

[0003] In the prior art, most of the ambient light control systems on the market currently rely on physical buttons, touch screens or preset modes, and lack intelligent and personalized voice control functions. In addition, traditional systems often have problems such as poor scalability and high maintenance costs. Summary of the invention

[0004] In view of the above problems, the present invention provides a voice control system and method for in-vehicle atmosphere lights based on SOA, which can improve the level of automobile intelligence and meet the diverse needs of users. At the same time, the present invention integrates advanced voice recognition technology, SOA architecture design, efficient data processing and transmission mechanism and intelligent atmosphere light control algorithm, with low maintenance cost and high scalability.

[0005] On the one hand, the present invention provides a voice control system for in-vehicle ambient light based on SOA, the system comprising: a voice recognition module, an SOA adapter module, an SOA gateway module, an ambient light control unit and a data transmission and synchronization unit.

[0006] The speech recognition module uses a speech recognition model trained with deep learning technology, which can recognize multiple languages, accents and complex commands, and is used to recognize user voice information and convert it into text commands;

[0007] The SOA adapter module, as a bridge between the speech recognition module and the SOA gateway, converts text instructions into service requests that comply with SOA architecture standards, and also performs interface conversion, converting service requests into a format recognizable by the SOA gateway module to ensure accurate transmission of information;

[0008] The SOA gateway module is used for routing and protocol conversion. According to the content of the service request, the request is forwarded to the atmosphere light control unit. It also has load balancing and failover functions to ensure the stable operation of the system under high concurrent requests and automatically transfer the request to the backup unit when some service units fail.

[0009] The atmosphere light control unit parses specific control parameters according to the received service request to adjust the state of the atmosphere light;

[0010] The data transmission and synchronization unit serves as a high-speed and reliable data transmission channel between components to ensure the real-time transmission of information and the consistency and integrity of information;

[0021] Step S3: The SOA gateway module acquires and identifies the data, converts the data into a communication protocol, and transmits the data to the ambient light control unit;

[0022] Step S4: The ambient light control unit parses the received communication protocol to obtain specific control parameters, adjusts the state of the ambient light through the control parameters, and feeds back the current state information of the ambient light to the SOA gateway module to facilitate further monitoring and optimization of the ambient light.

[0023] Furthermore, in step S1, the speech recognition module recognizes the user's speech and converts it into a text instruction, and analyzes the context information of the text instruction and makes a preliminary intention judgment, specifically including:

[0024] Convert user voice into text, use long short-term memory network (LSTM) and convolutional neural network to perform deep learning on the text, and extract voice commands from user voice;

[0025] Use a recurrent neural network (RNN) to perform semantic interpretation and intent recognition on voice commands to obtain results.

[0026] Furthermore, in step S2, the standard service request format of the SOA architecture is specifically a data structure transmitted in the service interface, and the data structure includes a data name and a data type.

[0027] Furthermore, in step S4, the atmosphere light control unit parses the received communication protocol to obtain specific control parameters, wherein the control parameters include: color code, brightness value, and dynamic effect mode.
