【摘要】 本文介绍所建立的带传动实验装置的微机检测系统,是利用APPLE 机主板上的 GAME 插座来实现实时数据采集的,并在此系统中利用LM311 电压比较器组成模/数转换电路,所设计的硬件接口电路简单、有效、实用、经济,整个系统程序由BASIC 语言和 6502 汇编语言交叉组成,能实现数据采集、处理、显示、绘图、打印数据及曲线等功能。数据准确、可靠。更多还原

【Abstract】 A detecting system was deyeloped for the experimental set-upof belt driving by way of implementing real-time data acquisition throughthe GAME socket on the main frame of an APPLE microcomputer. In thissystem, the LM311 voltage comparator was used to form an A/D conversioncircuit with a hard-- ware interface designed simply,efficiently,practically andeconomically .The system was programmed using BASIC together with 6502assembly language and available for use in data acquisition, processing anddisplay, as well as accurate and reliable data/curve printout.更多还原
