在智能化仪器及微型机系统中,从现场采集的数据,经过微型机数据处理后,常常用显示器进行显示。常用的显示器件有:(1)显示记录仪表;(2)LED七段数码管;(3)CRT显示终端;(4)大屏幕显示;(5)打印机等。在这些显示方法中,显示记录仪表能连续进行显示和记录,但价钱比较贵,且为模拟显示,读数不方便,有一定的误差,所以只适用于老企业的技术改造,在新设计的微型计算机系统中不宜采用。LED数码管由于结构简单、体积小、功率低、响应速度快、易于匹配、寿命长、可靠性高等优点,因此,是目前应用最多的一种显示器。特别是在智能化仪表
In intelligent instruments and micro-computer systems, data collected from the scene, after the microcomputer data processing, often with the display. Commonly used display devices are: (1) display recorder; (2) LED seven segments of digital control; (3) CRT display terminal; (4) large screen display; In these display methods, the display recorder can continuously display and record, but the price is more expensive, and for the analog display, reading inconvenient, with some errors, it is only applicable to the technological transformation of the old enterprises in the newly designed miniature Computer system should not be used. LED digital tube due to simple structure, small size, low power, fast response, easy to match, long life, high reliability, therefore, is the most widely used display. Especially in intelligent instruments
