摘要
针对国内对于大型内外圆磨床运行状态表征手段较少的问题,以国产嵌入式控制器MT Robust-RIO为硬件核心,基于LabVIEW开发了一套表征磨床整体运行状态的监测系统.可实现磨床运行时的振动、声发射、温度、流量、压力信号的实时采集、存储和分析功能.系统利用硬件端不同模块,结合生产者-消费者模式实现不同信号的实时同步采集,建立预警机制,超出阈值则发出报警信号,防止磨削烧伤等不良工况发生.通过磨床磨削和空运转实验验证了系统对磨床运行状态的表征功能.
Abstract
In order to solve the problem that there are few ways to represent the operating state of large in-ternal and external cylindrical grinders in China.We use the domestic embedded controller MT RobustRIO as the hardware core,and use LabVIEW to develop a monitoring system to characterize the overall operat-ing status of the grinding machine.The system can real-time acquisition,storage and analysis of vibration,acoustic emission,temperature,flow and pressure signals during grinding machine operation.It uses differ-ent modules on the hardware side and combines the producer-consumer mode to realize real-time synchro-nous acquisition of different signals in different rates,establishes a warning mechanism,sends out an alarm signal when the threshold is exceeded to prevent adverse conditions such as grinding burn.The characteriza-tion function of the system for the running state of the grinding machine is verified by the grinding and dry running experiments of the grinding machine.
