| Abstract: | The design of a synchronous clock PC card is introduced. Based on Global Positioning System (GPS) technology, W77E58 microprocessor, ISA bus, BIOS clock interruption and program residing in internal memory techniques are used in the design of the GPS PC card. The hardware circuit of the PC card is also given. Moreover, an application example is introduced in power plant automation system, using the GPS PC card to synchronize the clocks of distribution control system (DCS), digital electrical hydraulic system (DEH) and sequence of event system (SOE). The principles and methods are further explained and the design methods of the hardware and the software interfaces are presented. |
