摘要
数据采集与处理是 Kj13矿井监控系统软件的重要环节 ,主机与主站之间的数据通信则是整个软件的基础。因而阐述了此系统如何用 DOS中断机制的串行通信、在主程序中采用循环查询方式 ,利用内存缓冲区指针与数据处理指针相比较的方法决定数据的实时处理以及存盘技术 ,解决上述两个问题的方法。
Data acquisition and processing is a key link of Kj13 coal mine monitoring system software,and data communication between host and main station is the basis of the whole software.Therefor,how to use serial communication of dos interrupt mechanism and cyclic query in main program,and the way of comparison between memory buffer position and data processing pointer to determine realtime data processing and storing in the system are expounded for data acquisition and processing.
