【摘要】 在医药、化工等行业的生产中,为了及时清除喷雾干燥塔内壁的沉积物,需在塔壁外多处安装振动器产生间歇振动.控制这些振动器工作的传统方式存在很多弊病,常影响生产顺利进行.本文介绍的多路振动自动控制仪,是利用单片微机实现对30个振动器的自动控制.文中重点阐述了整个系统的硬件电路、软件程序设计原理,以及抗干扰措施.这一新型装置的特点是:控制路数多、工作可靠、抗干扰能力强、造价低、体积小、振动时间和时间间隔方便可调,经济效益好.此外,在不改变硬件的情况下,只要软件稍加变动,便可满足不同的时间程序控制要求,因此有一定的推广价值。更多还原

【Abstract】 In medicines and chemical engineering many vibrators,must be installed on the outside wall of the spraying and drying tower to produce intermission vibration so as to eliminate the deposit on the inside wall of the spraying and drying tower.When the traditional work ways are used to control these vib- rators,they have a lot of shortcomings and they always affect production.This paper introduces"automatic control instrument for multiplexer channel vibrat- ion".It utilizes single chip microcomputer to control automatically thirty vibrators.The hardware circuit of the whole System,the design principle of the software and the measure of anti-disturbance are discussed emphatically. The characteristics of this new instrument are:multiplexer channel control, high reliability,anti-disturbance,low price,small volume, moreorer vibration time and intermission time are conveniently adjusted and it has better economic result and so on.In addition,on the condition of unchanging hardware,if the software is slightly changed,it satisfies fully the requirement of the variation time to control program.So it is worthy of popularization.更多还原
