| With the progress of the smart sensor web nowadays, the application of intelligent data acquisition system is widely noticed and it is recognized as the important method to improve the competitive power of the enterprises. For developing the intelligent data acquisition system, basing on the principle of intelligent data acquisition system researched deeply, the data acquisition instrument based on pc104 bus is developed. The main task in the thesis:(1) A data acquisition and analysis system for the smart sensor web, which is based on the status of the development in the virtual instrument and acquisition system, is developed and then designing the system based on the developed virtual instrument.(2) The pc104 bus structure's features are made full use of, for instance stacked connect, compact structure, high integrated level etc. Then building the intelligent data acquisition hardware system based on the embedded operating system Windows CE, This apparatus not only has the function of data acquisition and analysis, but also has the expandability function of digital It0 control, time clock and counter etc.(3) The software system of data acquisition is developed, and the function module of data acquisition system has finished.(4) Research on the communication between the data acquisition system and IsVIP system. Test the system, show the conclusion and compare with LabVIEW at the last. |
