【摘要】：铁路隧道超限时有发生,及时准确的掌握隧道限界尺寸变化是保障铁路行车安全的关键,具有重要意义。目前我国现有的检测设备费力、费时而且检测精度不高,在一定程度上制约了铁路运输事业的发展,因此动态下高精度、自动化检测成为当前研究的重点。检测软件作为隧道断面数据采集、处理及分析的工具,是检测系统的重要组成部分。本文设计并实现了一套铁路隧道限界检测软件系统。该系统实现了隧道断面数据的采集、处理与分析功能,提高了检测效率。本文工作主要分为以下两个部分:(1)设计并实现了铁路隧道限界检测软件系统,提高了限界检测的自动化水平。首先,针对隧道种类繁多、检测时干扰众多的情况,结合当前成熟的检测技术对检测软件进行了详细的需求分析,并给出了软件的设计目标;其次,利用结构化分析和设计方法,完成了检测软件系统的总体设计;最后,基于软件系统的总体设计,对部分子模块进行详细的设计与实现,并对软件进行了相关测试。(2)针对软件实现过程中制约软件处理效率的问题,提出了切实可行的解决方案。对于图像处理中计算量大、处理耗时较长的问题,采用多线程技术来提高处理速度;对于软件系统中大量小文件读取与存储效率低下的问题,采用软硬件结合的方式对存储系统进行优化,科学高效的管理数据。目前,本文设计开发的软件已投入试运行,经过实际使用,检测软件不仅各项功能指标达到设计要求,而且具有良好的人机交互体验,受到用户好评。
[Abstract]:The railway tunnel overruns occur from time to time. It is the key to ensure the safety of railway operation to grasp the change of the tunnel boundary size in time and accurately, which is of great significance. At present, the existing testing equipment in our country is laborious, time-consuming and low precision, which restricts the development of railway transportation to a certain extent. Therefore, dynamic high precision and automatic detection become the focus of current research. As a tool for collecting, processing and analyzing tunnel section data, the detection software is an important part of the detection system. In this paper, a software system of railway tunnel boundary detection is designed and implemented. The system realizes the function of collecting, processing and analyzing the tunnel section data, and improves the efficiency of detection. This paper is divided into the following two parts: 1) the software system of railway tunnel boundary detection is designed and implemented, and the automation level of the detection is improved. First of all, in view of the numerous tunnel types and the numerous interference in detection, combined with the current mature detection technology, the requirements of the detection software are analyzed in detail, and the design objectives of the software are given. Finally, based on the overall design of the software system, some sub-modules are designed and implemented in detail. In order to solve the problem of restricting the efficiency of software processing in the process of software implementation, a feasible solution is put forward. For the problem of large computation and long processing time in image processing, multithreading technology is adopted to improve the processing speed, and the efficiency of reading and storing a large number of small files in software system is low. The storage system is optimized by the combination of software and hardware, and the data is managed scientifically and efficiently. At present, the software designed and developed in this paper has been put into trial operation. After practical use, the testing software not only meets the design requirements, but also has a good human-computer interaction experience, which is well received by users.
