本文介绍将AppleⅡ微机首次用于一种工业控制——水电站机组生产过程实时控制。根据水电站机组生产过程特点,充分利用并开发AppleⅡ微机的功能,使之实现对机组各种工况过程的控制以及事故,故障的处理和追忆。控制系统重要内容之一是设计一个专用的控制接口电路板并选用若干集成电路块,以便将机组有关的开关量、模拟基信息按性质和作用分类分别输入AppleⅡ微机,经数据处理逻辑判断后,按需要发出各种控制命令,通过接口电路板控制机组。另一个重要内容是用BASIC语言进行控制程序设计,对常用于控制的面向机器的各种汇编语言来说,BAEIC语言具有面向使用者的通用性,它接近习惯语言,简明易写易懂而且功能很强,用在控制上极为方便。控制系统还充分发挥AppleⅡ微机各种外设磁盘、终端、打印机以及声响发生器的功能,存储应用控制程序、显示各种状态,按需要可打印表格、运行日誌、日发电量、日负荷曲线等,还可使用汉字。
This article describes the first Apple Ⅱ microcomputer for an industrial control - real-time control of hydropower station production process. According to the characteristics of hydropower station production process, make full use of the functions of Apple Ⅱ microcomputer to make it possible to control the process of various working conditions and to deal with accidents and faults. Control system is an important part of the design of a dedicated control interface circuit board and the selection of a number of integrated circuit blocks in order to switch the unit, the analog base information by nature and role of classification were input Apple Ⅱ microcomputer, the data processing logic to judge, Issue various control commands as required and control the unit through the interface circuit board. Another important content is to use BASIC language for control programming. For various machine-oriented assembly language commonly used in control, the BAEIC language is user-friendly and it is close to the idiomatic language. It is easy to understand and function Very strong, very convenient for use in control. The control system also gives full play to the functions of the Apple II microcomputer’s various peripheral disks, terminals, printers and audible generators, storage of application control programs, display of various states, printable forms, run logs, daily generation, daily load curve, etc. , Can also use Chinese characters.
