| Abstract: | The design and application of the PC card of GPS based synchronous clock were introduced. With GPS technology,and by using of high performance 80C32,0 type single board computer, PCI bus of PC computer, BIOS clock interrupt and the technology of resident internal memory, the different system clocks could be synchronized with GPS clock while the normal operation of each system was not affected. The circuit design and the programming method of the PC card were presented in detail. The application of the PC card in the synchronization of different control systems of a thermal power plant in Hubei province was introduced as well. |
