摘　　要：近年来,随着网络技术的大力发展,传统广播业务不断走向融合,催生技术系统走向整合,处理的信号不再局限于音频信号,分发的平台也不限于传统的收音机,而是扩展到微信、微博、广电机顶盒、融媒体App等网络渠道。提供这些服务的硬件种类繁多数量巨大,且日趋呈现小型化、智能化的特点,对技术安全提出了新的挑战。结合多年来运维实践,以系统底层的硬件输入输出为切入点,全面梳理信号流转,力求建立清晰的传输节点,有利于同类从业人员在复杂的环境中快速定位故障,清晰把控重点设备,寻找替代方案保障技术安全,同时提出针对现有系统未来改造升级的要点供专业人员参考。In recent years, with the vigorous development of network technology, traditional broadcasting services continue to converge,resulting in the integration of technical systems. The signals processed are no longer limited to audio signals, and the distribution platform is not limited to traditional radio, but extends to wechat, Weibo, radio and television set-top boxes, financial media apps and other network channels. The variety and quantity of hardware providing these services are huge, and the characteristics of miniaturization and intelligence are increasingly presented, which poses new challenges to technical security. Based on years of operation and maintenance practice, this paper takes hardware input and output at the bottom of the system as the starting point,comprehensively sorts out signal flow, and strives to establish clear transmission nodes, which is conducive to similar practitioners to quickly locate faults in complex environments, clearly control key equipment, and find alternative solutions to ensure technical safety.At the same time, it also puts forward the key points for the future transformation and upgrading of the existing system for the reference of professionals.
