| Abstract: | In order to meet the requirements of aero-engine external field detection,and overcome the defects of traditional data acquisition system,the design principle and realization method of aero-engine data acquisition system based on ARM are introduced.The microprocessor S3C2440 is taken as a core,the data acquisition instrument circuits were designed,ADC,SD card and related drivers were implemented with the embedded Linux operating system.The designed system can meet the requirements of off-line mode data acquisition and storage during test running of aero-engine.Moreover,the collected data can be uploaded directly to the PC via the network.Therefore,this system can provide theoretical guidance for all concerned to deal with aero-engine condition monitoring and data analysis,which has the characteristics of simple operation,high accuracy and accurate measurement results. |
