空管系统业务需要传输大量低速率语音数据以及高速的TCP/IP网络数据。相比传统基于大对数电缆的综合布线技术,光传输网络无论在链路速率、运行稳定性及实时网管等功能上都有较大的进步,更加适合分布较为分散但业务比较集中的空管系统。笔者以民航山东空管分局所使用的PCM接入设备+光环传输网的模式为例,给出了空管业务中光环网技术的合理应用模式,并对整个系统的设计原则及具体实现给出了细致的分析。
Air traffic control system business needs to transmit a large number of low-rate voice data and high-speed TCP / IP network data. Compared with the traditional cabling technology based on large number of cables, optical transmission network has made great progress both in link speed, operation stability, real-time network management and other functions, and is more suitable for distributed air traffic control system. Taking the mode of PCM access equipment + optical ring transmission network used by CAAC Shandong ATC Branch as an example, this paper gives a reasonable application mode of optical ring network technology in ATC and gives the design principle and implementation of the whole system A detailed analysis.
