The invention provides an automobile Ethernet vehicle-mounted power amplifier tuning method, which at least comprises the following steps of: calling a preset function program in a central control host by a user, and starting an HMI (Human Machine Interface) to realize interaction; the parameter monitoring module obtains functional parameters formed by interaction between the user and the HMI; packaging the function parameters through a preset protocol, and sending the packaged function parameters to an acoustic host configured with an SPI interface through the SPI interface; the acoustic host analyzes the preset protocol, extracts function parameters, and executes a corresponding instruction according to the function parameters to realize digital quantity adjustment of the DSP; the system is self-defined to be divided into four layers, hierarchical packaging and analysis are achieved, and data are distributed to different applications and distributed to a serial port bus. Through the custom protocol, layered transmission and analysis and specific function definition are carried out, so that the audio adjustment requirement can be met, and the user experience is improved.
本发明提供一种汽车以太网车载功放调音方法,至少包括:根据用户在中控主机中调用预设功能程序,启动HMI界面实现互动;参数监控模块获取用户与HMI交互所形成的功能参数;通过预设协议将功能参数进行封装后通过SPI接口发送至配置有SPI接口的声学主机;声学主机对预设协议解析后提取功能参数,根据功能参数执行对应的指令实现DSP的数字量调节;自定义分为四层,实现分层级封装与解析,实现数据分发至不同应用以及串口总线的分流。通过自定义协议,进行分层传输和解析以及具体的功能定义,使得能够满足音频调节的需求,提升用户体验。
