Measurement And Control System Design Of Simulator Stand Based Virtual Instrument Technology

The measurement of ejection mechanism is a very complex process. Measurement and control system research based on virtual instrument technology will improve testing efficiency and precision; it can acquire, analyze and process the realtime data, and can show consumers the results. Using the networking and database management technology can realize remote supervisory and control, storage and maintenance of testing data; it is convenient for data share.In the thesis, presents configure of system hardware by analyzing the testing object. The system adopts the PXI bus; it enhances system flexibility. Based the Top-to-Down, modularized and structured method, divides the system into five parts: Data Acquisition, Data Processing, Data Analysis, Data Replaying, Database Management and so on. Then realize the design by LabVIEW language. In the system, uses circular buffer and Windows multithreading technology, it ensures data integrality in the process of acquiring and prevents the miss and repetition of data.In addition, the paper discusses LabVIEW network communications and database management technology, analyzes similarities and difference of the communications and details the web server technology. In the thesis, presents the database management technology (query, add, delete and so on) between LabVIEW and Access based the LabSQL VIs.Finally, this thesis provides a summary of the research work and makes some recommendations for the future research.
