LonWorks飞行数据采集系统的网络通信

Network communication in flight data acquisition system based on LonWorks

LonWorks现场总线一般用于对传送速度和数据量要求不高的场合。文章提出了尽量增加数据报文长度和采用令牌管理节点的方法,有效地提高了LonWorks的网络吞吐量。在基于LonWorks的飞行数据采集系统中,采用了该方法来采集、处理飞行器在飞行过程中的高速、大批量的数据,取得了良好的效果。

The LonWorks is mainly used on the situation that the speed of data transmission is not high and the data size not large,and it cannot fully meet the demand of the flight data acquisition system. In this paper,in order to raise the network throughput of the flight data acquisition system based on the LonWorks,the length of network message is increased and the token managing node adopted to collect and process the large amounts of data at a high speed. And the result is satisfactory.
