The invention discloses a vehicle-mounted audio acquisition system and method based on a vehicle-mounted Ethernet. The system comprises a vehicle-mounted electronic function device, an audio acquisition and processing device and a vehicle-mounted Ethernet switching device. In the prior art, each function unit uses a microphone and a circuit which are independent of each other to carry out audio acquisition. Compared with the prior art, by using the system and the method of the invention, a vehicle-mounted Ethernet is composed of a vehicle-mounted electronic function device, the audio acquisition and processing device and the vehicle-mounted Ethernet switching device; when the vehicle-mounted electronic function device needs to use an audio signal, an audio request signal is generated, andthe audio acquisition and processing device acquires sound information based on the audio request signal and performs audio processing to obtain a target audio signal; and the target audio signal is fed back to the vehicle-mounted electronic function device through the vehicle-mounted Ethernet switching device, defects of complex vehicle-mounted audio acquisition and high overall cost in the priorart are overcome, and a vehicle-mounted audio acquisition effect is improved.
本发明公开了一种基于车载以太网的车载音频采集系统及方法,所述系统包括:车载电子功能设备、音频采集处理设备以及车载以太网交换设备,与现有技术中各功能单元都使用各自独立的麦克风和电路进行音频采集相比,本发明由车载电子功能设备、音频采集处理设备以及车载以太网交换设备组成车载以太网,在车载电子功能设备需要使用音频信号时,生成音频请求信号,由音频采集处理设备基于音频请求信号采集声音信息,并进行音频处理得到目标音频信号,通过车载以太网交换设备将目标音频信号反馈给车载电子功能设备,克服了现有技术中车载音频采集复杂,且整体成本高的缺陷,提高了车载音频采集效果。
