基于工控机的方波发生器的实现

The Realization of Square Wave Generator Based on Industrial Computer

在分析某型飞机发动机状态控制系统、进气道控制系统的测试需求的基础上 ,利用PCL - 818L卡模拟发动机转速信号连续变化 ,介绍了该卡产生方波的工作原理、软件的开发方法以及驱动程序 ,使用结果满足测试需求 ,表明该方法有效可行。

On the basis of analyzing the test demand in the mode control system and intake control system of a certain type of aircraft engine, and through simulating the continuous variation of engine speed signal with PCL-818L card, this paper presents the operating principle of the card in generating the square wave, and introduces the development of its software and the driving program. The result shows that the method is effective and feasible.
