st 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 out redundant data, reduce storage space. As this will be the data acquisition module to set two different data flows Way Line: not all the way to reduce the sampling realtime data display program。 all the way with extracted onedimensional array of ways to reduce with the frequency, form a new array is written to disk Save. Data analysis include: data conversion and display, data points analysis, graphics processing, etc. Detection system posed of many forms of hardware, typically a sensor devices and converters, signal conditioning box, data acquisition card, the puter. The research is the hardware used consists of sensors, intelligent instrumentation data converters. Intelligent Instrumentation also known a
