Bluetooth Wireless Data Acquisition And Analysis System Developed

There are many problems in traditional data acquisition and analysis system, For example there are many troubles in jointing the devices, the development periods of software is too long, the capability of operation to the interface is not good, and the function of the software system is not easy to extend.In this paper, at first the bluetooth technology is introduced briefly, and present the characteristic of bluetooth technology. Based on the above presentation the project of the data acquisition and inspection software system is presented. Then the characteristic of the data analysis and processing system which are made by LabVIEW based on Visual Instrument technology is introduced.The data acquisition and analysis system combined with the bluetooth wireless data transmissions module, can realize different mode data acquisition on eight channels and PID control on two channels, and the data that were acquired can be processed by many kinds of processing methods just as signal pretreatment, signal trend detected, classic spectrum analysis, modern spectral estimation and self-suit signal filtering.
