基于FPGA技术的中波广播发射台自动化播控系统设计与实现

The Design and Implementation of Automatic Broadcasting Control System for Medium Wave Broadcasting Transmission Station Based on FPGA Technology

针对目前中波广播发射台普遍采用的集中控制管理模式可能导致多个频率设备停播的安全事故等问题,通过对中波广播发射台自动化播控系统组织架构的解析,结合现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)技术,提出中波广播电视台自动化播控系统设计程序和实现方法,解决单机自动化难点问题,满足“自主响应、自动播控”自动化播控机房的安全播出要求,为中波台的稳定运行提供技术支撑。

In view of the current problems such as security accidents that may result in multiple frequency equipment being shut down due to the centralized control management mode commonly adopted by medium wave broadcast transmitting stations,this paper analyzes the organizational structure of the automatic broadcast control system of medium wave broadcast transmitting stations and combines the Field Programmable Gate Array(FPGA)technology,put forward the design program and implementation method of the automatic broadcast control system of medium wave radio and television station,solve the difficult problems of single machine automation,meet the safety broadcast requirements of"autonomous response,automatic broadcast control"automatic broadcast control room,and provide technical support for the stable operation of medium wave station.
