摘要
设计了一种车载工程机械远程无线数据采集监控系统,该系统包括数据采集终端和数据监控中心。数据采集终端以LPC2378微控制器为核心,负责数据采集、存储、传输;数据监控中心负责接收、处理数据采集终端传输来的数据和远程配置数据采集终端工作模式。该系统数据采集通道丰富多样,可采集多种输出形式的工况信息和GPS定位信息;采集数据可实时传输,亦可本地缓存,无线通讯有效时,采集数据可实时回传至数据监控中心,无线通讯失效时,采集数据可本地存储至外扩存储器,保证采集数据不丢失;该系统适用于车载工程机械远程数据采集监控。
We designed a remote ＆ wireless data acquisition and monitoring system in engineering machinery, including the data acquisition terminal and the data monitoring center. Based on LPC2378 MCU, the data acquisition terminal can complete the acquisition, storage, and transmission of data. The data monitoring center can receive and deal with the data from the data acquisition terminal, and configure the data acquisition terminal remotely. The system has diverse data acquisition channels, it can acquire data of various working conditions with different output type and GPS location. The acquired data can be transmitted in real time, or stored locally. When wireless communication is in effect, the data can be transmitted to the data monitoring center in real time. When wireless communication is not in effect, the terminal can store the acquired data in the local extended memory to prevent data loss. The system can be used in remote data acquisition and monitoring in engineering machinery.
