摘要
AT总线智能、高速、同步交流信号采样板以Intel／k司生产的80186CPU为核心。数字电路部分采用GAL设计、DMA控制、双口RAM内存映像、16位AT总线接口等技术；模拟电路部分采用高速、高精度芯片。实现了16路通道同步、等间隔采样，速度达16O0次人，单点最高达IOO千次人，采样精度为0．1％；同时，实现了根据信号输入值进行1～256倍增益自动调整，依据预置判据实现故障录波等功能。在功能和性能上完全满足变电站综合自动化数据采集的需要。
A high-speed synchronized and intelligent AC signal samp1ing board with AT bus is developed. which employs lntel 8Ol86 CPU as its core. It implements l6-channel synchronous and equal-time cycle sampling with speed up to l600 samples per second (the highest speed of single channel reaches loO kilo samples per second) and O. 1 % accuracy. The functions of automatic gain adjustment on sampling values as well as fault waveform recording are also accomplished. It meets the requirements of data acquisition of integrated substation automation.
