【摘要】：嵌入式技术在当代飞速发展，与此同时，工程领域锚杆无损检测设备也因其迅猛发展而向着结构更轻便、性能更优越、操作更简单的方向发展。在矿山、建筑等领域中，锚杆锚固的安装质量检测一直是一个亟待解决的问题。本文基于嵌入式的锚杆无损检测系统研究就是结合国家自然科学基金项目（项目编号：5060774）“基于伪随机信号的锚杆动态响应与智能检测研究”进行研发的。本人在充分查阅和研究嵌入式和锚杆无损检测技术的发展历程和发展方向后，针对锚杆无损检测技术的计算量大和数据筛选量大的特点结合工业中的实际需求，采用了具有超强运算能力的最新嵌入式ARM11处理器S3C6410作为便携式硬件平台，选择了扩充性、裁剪性、多线程性和实时性都很强的Windows CE6.0作为嵌入式操作系统。在嵌入式系统硬件方案设计过程中，针对ARM芯片的特点，对驱动程序和电路进行了扩展和改良，自定义了专门针对S3C6410开发板的BSP，并导出了SDK用于之后软件的开发。在仔细分析了Windows CE系统的体系结构、开发平台搭建方法和内核的定制、移植方法后，利用Platform Builder完成了Windows CE6.0系统的移植。应用程序设计方面，充分利用了Windows CE系统与Windows桌面系统的可兼容性，利用Visual Studio2008集成开发环境和VB.NET程序设计语言，，采用面向对象的程序设计方法完成了无损检测软件的界面显示、参数设置、波形显示和数据分析四个模块的功能设计，并提出了信号FFT和改进FFT分析方法。该基于嵌入式的便携式锚杆无损检测系统集信号采集、数据管理和数据分析处理于一体，同时具有波形显示、参数设置、频谱分析等多种功能。针对锚杆无损检测的实际情况，该设备具有体积小、便携带、功耗低、操作简单功能扩展性好，便于二次开发的优点。该系统的研究在锚杆无损检测技术向便携式嵌入式平台的移植方面做出了有益的探索。
[Abstract]:With the rapid development of embedded technology, the nondestructive testing equipment in engineering field is developing towards the direction of lighter structure, better performance and simpler operation because of its rapid development. In the field of mine and building, the quality inspection of anchor anchoring has always been a problem to be solved. In this paper, the research of anchor bolt nondestructive testing system based on embedded system is developed in conjunction with the National Natural Science Foundation of China (item No.: 5060774) "dynamic response and Intelligent Detection of Anchorage based on pseudo-random signal". After fully consulting and studying the development history and development direction of embedded and anchor nondestructive testing technology, aiming at the characteristics of large amount of calculation and large amount of data screening of anchor nondestructive testing technology, I combine with the actual demand of industry. The new embedded ARM11 processor S3C6410 with super computing ability is adopted as the portable hardware platform, and the Windows CE6.0 with strong expansibility, clipping, multithreading and real time is chosen as the embedded operating system. In the process of hardware design of embedded system, according to the characteristics of ARM chip, the driver and circuit are extended and improved. The BSPs which are specially designed for S3C6410 development board are defined, and the SDK is used in the later software development. After analyzing the architecture of Windows CE system, the method of developing platform building and the customization of kernel and transplanting method, the transplant of Windows CE6.0 system is completed by using Platform Builder. In the aspect of application program design, the compatibility of Windows CE system and Windows desktop system is fully utilized, and the interface display of NDT software is accomplished by using Visual Studio2008 integrated development environment and VB.NET programming language, and using object-oriented programming method. The function design of four modules, including parameter setting, waveform display and data analysis, is presented, and the signal FFT and improved FFT analysis method are proposed. The portable anchor nondestructive testing system based on embedded system integrates signal acquisition, data management and data analysis and processing, and has many functions, such as waveform display, parameter setting, spectrum analysis and so on. In view of the actual situation of non-destructive testing of anchor rod, the equipment has the advantages of small volume, easy to carry, low power consumption, simple operation, good expansibility, and convenient for secondary development. The research of this system has made a beneficial exploration in transplanting the bolt nondestructive testing technology to the portable embedded platform.
