This paper mainly studied the realization and application of cable fault data acquisition system using the PCI bus.With the development of electric power industry, the possibility of the cable fault happening is also becoming more and more greatly. However, up to now, the mature technology for cable fault location is mostly based on off-line at home and abroad. There are not efficient methods for cable fault location on-line, so this topic has an exigently realistic significance.Cable fault location on-line bring forward higher request for data gathering and processing. The PCI bus protocol is so intricacy and it is one of the most competitive bus criterions for data acquisition technique, but it's hard to design the appropriate digital logic interface circuit for PCI.There are two effective schemes to realize the interface conveniently at present: One is to adopt CPLD or FPGA and the other is to adhibit special interface chip.Depending on one cooperatiove project,this thesis discusses the technique on the interface of data acquisition board based on PCI bus。Contrast has been made between the above two schemes, and finally the paper adhibits the second—PCI9054 to design the interface circuit based on PCI bus.In the first part of the paper, the protocol and electrical attribution of the PCI will be introduced.Then in the second, the way and method of realizing the hardware of the data acquisition system will be discussed.The thesis includes the design of hard circuit, PCB (Printed Circuit Board), Driver and application soft.The detailed functional modules consist of analog digital conversion module,digital analog conversion module,PCI protocol conversion module,control logic,clock circuit and configuration circuit. The hard circuit is drawn employing circuit soft Protel 99SE. The driver is developed using developing tool DriverWorks and the application soft is programmed making use of advanced programming soft Visual C++ 6.0. The upper computer procedures which are compiled by VC++6.0 language and MATLAB language that can accomplish some assignments about real time transmission of data, image-based rendering, file saving, wavelet analysis and spectrum analysis. And parts of the system that can be enhanced in the future by other students are also described.Finally, the system is tested in this paper. The test results show that the hardware and software can normal work and meet the requirements of cable fault location on line.
