摘要
本系统利用自制接口软、硬件将一台IBMPC／XT微机与多种输出特性不同的仪表相联，实现稳态数字量和瞬态模拟量的分时采集与数据处理。可提高原台架自动测试水平及试验结果的可信度，并使台架功能得到扩展。此外，介绍了系统结构、工作原理和软、硬件配置状况，及其功能和特性。
The system consists of a IBM PC/XT microcomputer connecting with several instruments, Which have different output characteristic. The hardware interface and software are made by ourself The system can realize time-sharing acquisition and processing for digit data under steady state and analog quantitics under transient state. The automeasurement level and the measuring confidence level have been improved and the functions of cngine test bed expanded by tbis system. In this paper, the configuration, princple, hardware and software, as well as measuning functions about this system are presented.
