基于嵌入式技术的机车轴承故障在线监测系统设计

Design on On-line Monitoring System for locomotive bearing fault based on embedded technology

从机车安全运行角度出发,分析现有机车轴承故障诊断系统中存在的弊端,介绍机车轴承故障在线监测系统的工作原理和主要构成,论述系统的软硬件设计,系统的数据采集与数据处理2大模块的设计,系统采用数据融合技术对多传感器采集的数据进行实时处理,在硬件装置的基础上移植μC/OS-II实时操作系统,并由应用软件完成机车的CAN总线通信,GPRS通信,车载显示,语音报警等功能。该系统经过半年多的实际运行,结果表明该系统结构设计合理,实用性强。

From the perspective of locomotive safe operation, it was analyzed the defects of the existing Locomotive Bearing Fault Diagnosis System, described the working principle and main components of the Locomotive Bearing Fault On-line Monitoring System, detailed the hardware and software design of the System, expatiated on the two major module design of the data collection and data-processing, the System used data fusion technology for multi-sensor data acquisition in real-time processing, transplanted la C/OS-II Real-time Operating System on the basis of the hardware device, and completed the locomotive CAN bus communication, GPRS communication, automotive display, voice alarm, and other functions by the user application software. The System was more than six months after the actual operation, the result showed that the System architecture designs reasonable, and was a strong practicality.
