Research And Implementation Of The Can Communication Network Based On Wince

CAN(Controller Area Network)as a kind of influential field bus in Industrial Automation,get more and more wide use.It's first applicatied in Automobile system, The leval of visualization is not very high. This article is to resolving the problem meet in the Kunlun Tongtai company during my practice period.Under Windows CE , This article explained how to tailor the drive of CAN card for Mainboard of touchscreen to implement it's communication,and how to make it to be a whole efficient visualization control system.. This topic mainly solves several key questions:(1) The design of CAN driver basis the CAN protocols. (2) The tailored of CAN driver in the Windows CE kernel, what make the CAN communicaition transparent for the sofeware users.(3) The adopted of appropriate of assign strategy, what satified the demand of the real-time capability and most delayed time of the not- real-time data.(4) The optimized the efficenciy and capability of the CAN communication. The design of rational data structure and the manage of the deposit can ensure the good capability even the ample data is send or accepted.(5) The testing of the system is also researched in this article, the stage of testing contains the capability,securiy,compatible of the communication.With the result of the issue, we design a system used the product of MCGS, which realized CAN communication under Windows CE .The system eventually satified the demand of the users, and reached the expectant targetAt the last of this article , it summarized the whole reaesrch and bringed forward the research topic and target for the future.
