Virtual Instrument Technology-based Neural Information Online Analysis Platform

In recent years, along with the development of computer, the medical instruments for acquisition and processing of medical signals are increasingly developing into automatization and intelligentization. Owing to only single signal and very high price, many import medical equipments having ability of data acquisition have not far-ranging been applied by hospital and laboratory. Therefore, the main content of this thesis is set up a universal platform of experiment, which can acqire and real-time analysis the neural information, and have better expansibility and agility. In view of the complexity of the neural information and the difficulty of signals collection, we achieve framework of the system, which consist of software function and hardware function, and actualize collection and processing of EEC and ECG. Moreover, in the extending phase, we strengthen the function of the system, and achieve the deep stratum of neural information.We introduce and analyse the theory structure and meaning of virtual instrumentation in detail , and emphasize analysis of structure and characteristic of virtual medical signal processing instrument in this paper,. Basing on this, we research the methods of designment and achievement of the system, it is crucial to design and achieve the software function of the system.In term of the structure of virtual instrumentation, first, we design and achieve the hardware, have emphasis on the signal amplifier for the sake of signal collection in the processing of achieving the thesis. Second, we design and achieve the function of software with object oriented. The software function consist of signal real-time collection, wave display , signal storage and management, signal analysis. With the Measurement studio6.0 of NI and it' s controls, we exploit the system, and enhance the efficiency of exploitation. Finally, many one-up methods of signal processing are applied. It is effective to sieve interferential signals and achieve analysis of EEG and ECG.In the end of this thesis, we put forward some methods of making up the system limitation to ground the system in the extending phase, and open up prospects for the domain of medical signals processing in china.
