【正文】 software features powerful virtual collection system. This article first describes the development of virtual instrument and acquisition system based on the principle of the acquisition system for analysis, developed a 16bit precision of the RS232 data acquisition card. In the LabVIEW software environment, the establishment of a virtual serial data acquisition system. Subsequent analysis of software architecture, bined with ponent technology, the idea proposed by measuring the functional ponents and focuses on serial munication, measuring functional ponents and data management module implementation. Finally abV menu and Queue work Ew technology systems integration. Data recording, storage modules. data records of test data storage module for record keeping to facilitate later analysis and the accumulation of historical data. LabVIEW provides a lot of data storage methods, this paper is Excel table to store data records. Data storage and data acquisition and realtime display with the required very different. Data acquisition and realtime display the required sampling frequency is high, if the data storage module also used this sampling frequency will produce a large number of redundant data, which will take up a lot of hard disk space, need to adopt lowerlow sampling frequency, methods to filter
