民航自动转报系统中智能程控异步单元的深入研究与故障诊断

In-depth Study and Fault Diagnosis of Intelligent Programmable Asynchronous Unit in Automatic Relay System of Civil Aviation

智能程控异步单元(以下简称异步单元)是民航空管技术装备发展有限公司自动转报系统中设备之一。无论是在DMHS-H大型、DMHS-M中型、DMHS-R/S小型系统或者是最新的DMHS-V转报系统中,异步单元均是最主要的接入设备。主要为终端接口与转报服务器之间提供数据转换,其作用不言而喻。在文章的研究中,主要针对异步单元的原理、数据抓包以及故障诊断等方面进行全面的分析与阐述。

The intelligent programmable asynchronous unit(hereinafter referred to as the asynchronous unit)is one of the equipment in the automatic relay system of CAAC ATC Technology and Equipment Development Co.,Ltd.,Whether in DMHS-H large,DMHS-M medium,DMHS-R/S small system or the latest DMHS-V relay system,the asynchronous unit is the most important access device.It mainly provides data conversion between terminal interface and forwarding server,and its role is self-evident.In this paper,the principle of asynchronous unit,data capture packet and fault diagnosis are analyzed and expounded comprehensively.
