Design And Development Of The Data Acquisition System On The Basis Of VC Software Developing Platform

In data gather and the process system of the industry how improve the real-time character and commonability, it is the question that the designer should consider emphatically. The author combines project reality, propose utilizing many thread and Dynamic Link Library in data gathering and the process system, can improve systematic real-time character and commonability greatly, especially the occasion expected much in real-time character, the Method that this text puts forward has higher reference value.In data acquistion and the process system, A thread is responsible for the collection and analysis of the data, other several threads are responsible for making corresponding processing according to the information gathered. In different application, have different treatment analytical methods to the data that are obtained , we make different treatment analytical method into Dynamic Link Library to deal in main thread and data acquisiton, thus realize the commonability and expansion of the system.This paper has been introduced under the environment of windows emphatically, utilize such technology as multimedia timer , many thread and news ,etc, to discuss the method of the real-time data acquistion , has solved someproblems while gathering in real time, having succeeded in realizing accuracy and real-time that the data gathering , and it is good to run.This paper will combine the industry monitoring software of one senser technique center, recommend how to realizes the serial data acquistion with effective and high speed by utilizing Visual C ++ 6.0.
