摘要
针对目前我国基于嵌入式的超声导波管道检测仪器稀少的现状,提出了一种基于ARM9的管道超声导波检测系统的设计方法,进行了硬件的设计、驱动程序和应用程序的开发。硬件部分采用模块化设计,便于开发过程中的测试和后续的开发。使用基于ARM920T架构的微处理器S3C2440A作为系统的硬件平台,选用Linux2.6.30版本的操作系统内核,应用程序使用Qt/Embedded4.5编写。实验表明,系统各部分运行正常,能发射超声导波窄带激励信号,可以对信号进行放大、采样和显示,实现了系统设计的功能要求。
To meet the current requirements of ultrasonic guided wave test equipment based on embedded system in China,a design method based on ARM9,of ultrasonic guided wave test system for pipe was proposed.The hardware was designed,drivers and application software were developed.The hardware was designed with a modular structure,it was convenient for debugging and further development.S3C2440A microprocessor based on ARM920T was used for embedded hardware platform,the kernel of the operating system was Linux 2.6.30,application software was developed with Qt/Embedded 4.5.The results show that all parts of the system can normally operate,and the equipment can properly send the narrowband excitation signal for ultrasonic guided waves,it can amplify,sample and display the signal.The instrument can meet the functional requirements of system design.
