摘　　要：为了解决广播电台外场的广播直播特别是在移动中直播信号的传输方式受条件限制而难以进行或无法完成的问题,我们利用了现有的公共无线网络4G+高清语音平台的通讯链路,将具有VoLTE功能的手机作为传输主体与物联网远程WiFi模块及控制电路相联,构成现场节目语音信号的无线传输及手机APP远程自控切入到广播机房音频端口的直播系统,为广播电台户外直播、转播工作增加了一种可行性的手段和低成本传输语音信号的补充方案。In order to solve the problem that the transmission mode of live broadcasting in outdoor radio stations,especially in mobile broadcasting,is difficult to carry out or can not be completed due to the constraints of conditions,we use the communication link of the existing public wireless network 4 G+HD voice platform to connect the mobile phone with VOLTE function as the transmission subject with the remote WiFi module and control circuit of the Internet of Things to form a live program.The wireless transmission of voice signal and the remote automatic control of mobile phone APP cut into the live broadcast system of audio port in the broadcasting room add a feasible means and a low-cost supplementary scheme for the outdoor live broadcasting and broadcasting work of the broadcasting station.
