LTPB接口控制文件ICD的有效性判定

LTPB INTERFACE CONTROL DOCUMENT VERIFICATION

ＩＣＤ文件反映了电子综合系统的数据流特征，保证航电系统综合成功的一个要素是数据流完整、实时的传输。介绍了接口控制文件ＩＣＤ的制定方法。从网络协议、消息参数出发，对网络传输特性进行了深入研究，在给出合理的网络参数设置方法的基础上，提出了ＩＣＤ文件定义的数据流完整、实时传输的充要条件和工程实用的判定方法。

An ICD document describes data stream characteristics of the electronic integrated system. To achieve an integrated avionics system, complete and real time transfer of data is an important factor. This paper explains the ICD design method. From the network protocol and message parameter, network transfer features are studied. Based on a reasonable algorithm of the prime network parameter, a necessary and sufficient condition and a practical method are proposed to verify data stream integrity and real time transfer for the ICD document.
