单片机矿井多路数据采集监测系统

介绍了一种基于8031单片机的多路数据采集监测系统，该系统适用于中、小型矿井，采用双CPU控制，上位控制机和下位监测机均采用8031单片机，下位监测机采集数据，上位控制机控制下位监测机，并进行数据处理、数据显示、键盘输入和系统报警等工作。通过单片机通讯的方式实现数据与控制指令的远距离传输。

The Data Collecting and Monitoring System of Mine Based on Sing le-Chip Microcomputer

This paper introduces a data collecting and mon it oring system based on 8031 single-chip microcomputer. The system is applicable for small and middle sized coal mine. Two CPU are used in the system. The type o f CPU is 8031 in both upper control microcomputer and lower Monitor microcompute r of it. Its lower Monitor microcomputer is used for collecting data and the upp er control microcomputer for controlling the lower Monitor microcomputer, data p rocessing and displaying, keyboard inputting, system alarming etc. In this way, the data and the controlling instruction are transmitted in a long distance.
