摘要
为了有效监测和诊断铁路机车走行部及传动装置的故障,文中在原有研制产品的基础上,设计一个基于GPRS的嵌入式Internet机车故障远程诊断系统。简要介绍了系统组成,重点分析了实现系统功能而采用的共振解调检测技术和基于GPRS的嵌入式Internet远程通信技术,最大程度地实现了诊断资源共享。当机车故障振动的幅度分贝值Adb即使没达到55.0dB,车载系统也能将故障信息传送给地面控制中心,且延时小于3s,保证了故障实时诊断的准确率达100%。
In order to effectively monitor and diagnose the mischief of locomotive operation and gearing installation, a remote diagnosis system for locomotive engine based on embedded Internet of GPRS is designed.The composition of this system is briefly described, the remote communication technology based on resonance demodulation and embedded Internet of GPRS for realizing system functions is emphatically analyzed, and diagnostic resource sharing is realized to the maximum. Even if the mischief vibration amplitude of locomotive engine is less than 55.0 dB, the information is transmited as usual to the ground control centre and the delay is less than 3 seconds, thus the success rate of real-time diagnosis is almost up to I00%.
