概述“酚酞缩合微机自动控制系统”是以微型计算机为核心的闭环控制系统,主机选用了TP-801B型单板机经过扩展,配置了键盘接口、CRT显示、打印机、操作面板控制接口、A/D、D/A转换板等,具有对各种现场参数的自动采样、分析、计算、控制和显示、打印、报警的功能,并以分时扫描方式对整个车间的多套设备实现群控.酚酞缩合反应时间较长,经过实际运行观测,被控对象不是线性定常系统.例如,反应初期,被控对象为液状,随着反应时间的加长,逐渐粘稠,反应中期粘稠度可达沥青状态,至反应后期,反应物变为固
Overview “Phenolphthalein condensation microcomputer automatic control system ” is a microcomputer-based closed-loop control system, the host selected TP-801B-type single-board machine has been extended to configure the keyboard interface, CRT display, printer, control panel control panel, A / D, D / A converter board, etc. It has the functions of automatic sampling, analyzing, calculating, controlling and displaying, printing and alarming on various field parameters. Control of phenolphthalein condensation reaction time is longer, after the actual operation of observation, the controlled object is not linear system.For example, the initial reaction, the controlled object is liquid, with the reaction time is lengthened, gradually viscous, mid-term viscosity Up to asphalt state, to the reaction late, the reaction becomes solid
