【摘要】 测斜技术是测量方法和仪器相结合,测量和监控地下空间的位置及其方向位移、倾角变化等,测斜仪系统广泛应用于铁路交通、水电大坝、桥梁、建筑、矿山、地质环境勘察及其它岩土工程领域,以保证岩土工程重要环节的安全顺利进行。本文从测斜仪的系统组成和工作原理出发,结合基于ARM9的嵌入式系统开发原理及过程,从系统的软硬件设计、操作系统的移植、图形用户界面的开发、嵌入式数据库的应用等方面对现场智能测斜仪的设计与开发进行了重点研究。该仪器以ARM920T内核芯片S3C2410作为处理器核心,并围绕其进行了硬件系统的设计。采用芬兰VTI公司先进的倾角测量传感器芯片SCA100T-D02作为敏感元件,采用LCD显示器、触摸屏实现了数据显示和人机交互,采用USB接口、串口实现与PC的数据传输,另外还包括传输电缆、专用测斜管、可充电电源等部分。在对硬件体系结构和linux操作系统进行深入分析的基础上,完成了嵌入式linux操作系统的移植,选用MiniGUI作为图形用户界面支持系统,实现了嵌入式数据库SQLite的应用。成功开发了包含中文字符输入的MiniGUI软键盘模块、基于数据库的测量数据管理系统、连接倾角传感器的SPI设备驱动程序、测斜仪图形界面应用程序等,使整套系统具有测量精度高、稳定可靠性好、使用简便和测量现场化等优点。更多还原

【Abstract】 Inclinometer technology is the measurement methods and instrument combined, measuring and monitoring the location of underground space and the direction of displacement, angle changes, inclinometer system widely used in railway transportation, hydroelectric dams, bridges, construction, mining, geological environmental surveys and Other infrastructure engineering, to ensure the important link of infrastructure construction carried out safety and smoothly.On basis of inclinometer system composition and operational principle, combining ARM9-based embedded system development process and principles. To design a field intelligent inclinometer, This paper emphasis on research of system hardware and software design, operating system transplant, development of graphical user interface, and embedded database applications and so on. inclinometer uses ARM920T core chip S3C2410 as processor, then accomplished hardware system design focus on it. Which adopts VTI’s advanced angle sensor chip SCA100T-D02 as sensitive components, uses LCD monitor and touch-screen to realize data display and man-machine interactive control, uses USB interface and serial port to carry out data transmission, in addition hardware includes transmission line, special angle test tube, rechargeable power supply and other parts.On basis of in-depth analysis about hardware architecture and linux operating system, completed embedded linux operating system transplant, used MiniGUI as graphical user interface support system, and realized embedded database SQLite application. successful developed MiniGUI soft keyboard module include of Chinese character input, measurement data management systems based on database, SPI driver for connecting angle sensor, GUI application program. So the whole system has many advantages as high accuracy, good reliability, good stability, easy use and field measurement.更多还原
