起重设备的嵌入式数据采集系统研究

摘要

To establish a remote monitoring and fault diagnosis system for lifting equipment,the paper proposes an embedded data acquisition system for PLC data source and introduces design ideas of the software and hardware.The data acquisition system of lifting equipment carries Siemens PLC,adopts the cortex-A9 chip and embedded Linux operating system,and takes Freescale i.Mx6q chip as its core,making it capable of data acquisition,storage and forwarding through Siemens FETCH/WRITE communication protocol of Ethernet.Now the system has been successfully applied in industrial site.%为建立起重设备远程监控和故障诊断系统,提出一种针对PLC数据源的嵌入式数据采集系统方案,介绍了其软硬件设计思路.数据采集系统基于cortex-A9芯片和嵌入式Linux操作系统,采用飞思卡尔i.Mx6q芯片为核心,通过西门子FETCH/WRITE以太网通信协议,实现了对搭载西门子PLC起重设备的数据采集、存储及转发.该数据采集系统已经成功运行于工业现场.
