| Abstract: | The real-time kernel μC/OS-Ⅱwas replanted on Intel CHMOS high-powered 16-bit singlechip 80C196KC , two high-speed ,8-channel ,14-bit data-acquisition chips with four simultaneous track/holds named MAX125 were selected to organize the real-time and high-speed data acquisition system. At the same time by the in-system programmable high density logic device named Lattice ispLSI1032 the digital data acquisition and output channels totaled 64 channels were extended. The communication between this data acquisition system and other systems can be set up by RS-485 communication bus. The data acquisition system introduced in this paper can be widely employed in electrical auto-control system where data acquisition speed , precision and real-time performance are strictly required. Undoubtedly this data acquisition system has much practical value. |
