Research of Component Technology in Open Control System

Openness of embedded control system is an important research field.Through using open architecture of embedded control system,that it can reduce the coupling degree of every part in control system,make higher reusability of software and easier to add new functions.So openness of control system and component technology becomes researched more nowadays.Based on the features of open control system and component technology,this article brings up an open architecture for control system to support component technology.And using component technology,with the existing software of LanTian CNC system,we made some improvements to decrease the coupling degree of the application modules that fulfills the open architecture's demand.At last,we did some tests on LanTian CNC to verify and analyze this architecture.
