摘要
为完成对某型弹载计算机的自动测试,设计一种模拟惯性组合输出电路。该电路硬件主要以基于PCI总线的数字量输入输出卡PCI 144DI/O及可编程定时计数器82C54为核心,电路硬件结构简单,使用灵活方便。控制软件基于LabWindows/CVI软件平台开发设计。实验证明,该电路完全能够模拟惯性组合输出脉冲宽度、脉冲周期及脉冲个数可调的脉冲信号,并且成本低、开发周期短。
To complete the automatic test of missile- borne computer,a kind of analog inertia combinational output circuit is designed. Its hardware circuit is based on PCI 144DI/O and programmable timing counter 82C54 as main kernal,the hardware circuit has simple structure and easy to use. The control software based on LabWindows/CVI. The experiment proves that the circuit can totally simulate the output of the inertia combination,control the length, the interval and the count of the pulse conveniently.
