摘要
语音信号的采集、传输、处理和分析在很多领域都有着非常广泛的应用,为了适应语音信号数据量大的需求、克服传统的有线采集系统使用不灵活和布线困难等缺点,设计了一种集成NRF24L01无线收发芯片、STM32F103ZET6处理器以及ENC28J60以太网传输模块的无线语音采集系统,设计实现了该系统的硬件和软件,并给出了实验测试结果。该系统传输速率高、工作稳定,可以实现对语音信号的采集和快速无线传输。
The acquisition,transmission, processing and analysis of the speech signals are widely used in many fields. In order to adapt to the speech signals＇ large quantity, and to overcome the disadvantages of the tranditional wire acquisiton system such as inconvenience and difficult to wire,this paper designs a wireless speech acquistion system which adopts the NRF24L01,STM32F103ZET6 and ENC28J60 as its wireless transceiver,micro-control and ethernet transmission unit. The paper discusses the hardware and software design of the system, and gives the results of the experiments. The system has high speed of transmission and stable operation, it＇s availible for speech acquisition and fast wireless transmission.
