摘要：

为了对船舶轴系双通道扭振进行测量,提出了一种基于ARM和RTX操作系统的扭振测量仪的设计。该设计以高性能ARM处理器LPC1788为核心,利用TT10K扭矩遥测系统,A/D转换器,信号前端处理模块实现振动信号的高速精确采集。将采集到振动信号的时域图形显示在LCD上。在ARM上加上RTX操作系统,可有效实现对上位机下达任务和板载资源的管理。

Abstract:

A design of torsional vibration measuring instrument based on ARM and RTX operating system is proposed for dual ship shafting torsional vibration measurement.The highperformance ARM processor LPC1788 is used as the core,and the TT10K torque telemetry system,an A/D converter,and a signal processing module frontend are employed for highspeed precision vibration signal acquisition.The time domain graphics of the collected vibration signals are displayed on an LCD.The addition of RTX operating system to ARM offers effective task assignment to the host computer and management of onboard resources.
