文章介绍了一种基于PC机和单片机的单总线多点数据采集系统以及系统主要部分的构成及作用。在单总线系统上,集数据采集与系统控制于一体,系统具有结构简单、经济、功能强的特点。在PC机温度监控系统的应用中给出了系统结构示意图,说明了主要部分的构成及作用,同时说明了软件的功能;在单片机温度监控系统的应用中给出了系统原理图及各部分的功能说明,同时给出了软件流程图;最后,基于数据挖掘的思想,讨论了有关数据处理的问题,提出了一种用人工神经网络进行故障诊断的方法,实现数据处理的智能化。
This paper introduces a single bus multi-point data acquisition system based on PC and single-chip microcomputer as well as the composition and function of the main part of the system. In the single-bus system, set the data acquisition and system control in one, the system has a simple structure, economical, powerful features. The system structure diagram is given in the application of PC temperature monitoring system, which shows the structure and function of the main part, at the same time shows the function of the software. In the application of MCU temperature monitoring system, the system schematic diagram and the parts At the same time, the flow chart of the software is given. Finally, based on the idea of data mining, the problems about data processing are discussed, and a method of fault diagnosis based on artificial neural network is proposed to realize the intelligent data processing.
