摘要
为PC—1500袖珍计算机配备数据采集接口,可扩大其使用范围。本文详细介绍了PC—1500计算机15路带放大器的数据采集接口的设计情况,给出了电气原理图,并通过测试实例介绍了它的编程及使用方法。该接口的设计为农业机械或其它机械进行计算机测试提供了一种手段。
Designed Data Aquisition Interface (DAI) PC-1500 minicomputer can be used in much wider range. This paper describes-the design of 15 chambles DAI with amplifier of PC鈥?500 minicomputer in detail, gives a figure of circuit princinplc and introduces the programing and applied method by test example. DAI gives a method for PC-1500 minicomputer applied in test of agricultural tools or other kind of machines.
