Research Of Configuration Software Based On Field Bus

At present, the configuration software is not applied too much in the CAN bus control system.Generally,the exploitation of computer-Monitored software of CAN bus mainly has two kinds of methods:the first method is exploiting the computer-Monitored software alone,which realizes the communication between the upper computer and the lower computer,but this must bring forward repeat labour;the second method is using the connecting tool,which connects CAN bus and commercial configuration software, but commercial configuration software is expensive, this lead to the medium-sized and small enterprises and universities teaching are very difficult to accept,and which doesn't reach the actual need of enterprises.So expoiting the CAN bus control system of the easy protocol and reliable communication is very necessary.The configuration software is built on the hardware flat of CAN bus control system. First,based on researching the system structure of FCS and configuration software, basic functions of configuration software was realized, general design scheme was made sure.This confituration software had the functions of real time database by adopting modularization designing,graphical configurate, I/O driver and so on.Secondly,these modules were designed and researched congretely.in real time database, the data object model,data memory, combining with Windows system,database configuration's ADO technique were studied ;in graphical configurate,multithread technique was adopted for improving the procedure efficiency, system was especially amicable on interactive;In I/O driver,it was made true by using of dynamic linking library (DLL),in the program of bottom communication,serial communication was realized concretely by MS Comm.Last,the configuration software was applied in CAN experiment teaching,which made the CAN bus control system which is controlled more concisely and directly by using it,linked with the internet more conveniently.The configuration software decreased effectively the repeat labor of exploiting the upper computer software by engineer, whose project developing efficiency was improved;And the configuration software was applied in universities CAN bus teaching.At the sametime,the exploitation of the configuration software was pushed based on CAN bus,as a reference for researching and realizing the configuration software of those fieldbus.
