| Abstract: | The paper introduces a low cost and high quality voice monitoring system based on DSP, which transmits data by Ethernet. The system includes a voice acquisition module and a voice transmission module.Voice acquisition module consists of a 16bit high speed DSP chip(TMS320VC5402) and a voice processing chip(MC14LC548), and uses DSP to control Ethernet controller 8019 to realize voice transmission, monitor the on-off state and the field playback function of system can be controlled by long-distance PC directly. The paper suggests a hardware design configuration and software design flow chart in detail. |
