MCS-51系列单片机具有丰富的I/O口,定时器以及中断系统等硬件资源和功能较强的指令系统,特别适用于控制领域中的应用。本文介绍的烟厂环境参数自动监测系统采用了以80C31单片机为核心的控制系统,具有自动化程度高、结构简单、成本低等特点。友好的操作界面和灵活的监控方式是本设计的两大特色,此外还扩充了掉电数据存储,语音报警,系统开机自检等功能,增强了系统的实用性。
MCS-51 series MCU has a wealth of I / O port, timer and interrupt system hardware resources and more powerful instruction set, especially for control applications. This article describes the cigarette factory environmental parameter automatic monitoring system uses a 80C31 microcontroller as the core of the control system, with a high degree of automation, simple structure, low cost and so on. Friendly user interface and flexible monitoring methods are two major features of this design, in addition to expanding power-down data storage, voice alarm, system POST and other functions, and enhance the system’s practicality.
