在现代工业生产中,一个以计算机为中心的生产过程控制系统或监测仪表常常安装多组静态LED显示器和声光报警装置,用以监视生产中的各种工艺参数。这些LED数据和报警信号,有时需要从控制室远传至生产现场或其他公共场所,供多人监看,以减少控制室值守人员。本文介绍的数据远传和放大装置,收、发部分各使用一片8048系列单片机,用串行传输方式,将一组五位静态LED显示器数据和报警
In modern industrial production, a computer-centric production process control system or monitoring instrument often houses multiple static LED displays and acousto-optic alarm devices to monitor various process parameters in production. These LED data and alarm signals sometimes need to be remotely transmitted from the control room to the production site or to other public places for monitoring by multiple people to reduce the number of personnel in the control room. This article describes the data transmission and amplification devices, receive, send part of the use of a 8048 series of single-chip microcomputer, with serial transmission, a set of five static LED display data and alarm
