工程机械工况参数微电脑监测系统的设计

Design of Micro computer Monitoring System of Operating Condition Parameter for Construction Machinery

本文介绍了以单片机为核心，由数据采集机、中继机和微机三部分组成的工程机械工况微电脑监测系统的设计思想及软、硬件设计技术。该系统的采集机直接安装在各种工程机械上，配用各种传感器，可以记录工程机械的工作日期、时间、电瓶电压、发动机转速、机油压力、机油温度、水温、振动等各种工况参数，在机械出现故障或参数越限时进行报警；采集机采集和存贮的信息由中继机传送到微机中进行离线分析和处理。

This paper introduces the design technique of software and hardware and design philosophy of micro computer monitoring system for construction machinery The monitoring system consists of data collecting machine,relay machine and computer based on single chip The data collecting machine and various sensors are directly installed on the construction machinery:All the operating condition parameter,i e operating date,time,battery voltage,engine speed,oil pressure,water temperature and vibration of construction machinery can be recorded It can alarm when parameter is over the limit value,or the machine fails Information from data collecting machine can transfer to the relay machine,then to the computer to conduct off line analysis and treat
