摘要
应用以嵌入式微控制器+微型PLC为基础的N+1播出控制系统,用一台备用发射机为多台主用发射机进行备份。分析了N+1播出系统的工作原理,提出了控制系统总体设计方案,采用多控制系统结构以及嵌入式技术能够分别实现增强系统适应性和降低系统成本的目的。采用该系统,如果主用发射机存在故障,能够及时的将备份发射机切换过去进行发射,大大地提高了播出的安全性。希望对调频发射系统具有借鉴意义。
Application based on the embedded microcontroller controller ＋ miniature PLC of N ＋ 1 broadcast control sys- tem, Using one standby transmitter is the main transmitter for backup . This paper analyzes the working principle of the N ＋ 1 broadcast system, puts forward the control system~ overall design scheme of multi control system structure, and sep- arately implemented embedded technology to enhance system adaptability and reduce the system cost. By using this system, if the primary fault with transmitter, can in time will backup switch transmitter launched in the past, greatly improved the security of the broadcast . Hope has reference significance to the FM launch system.
