【摘要】 设备巡检工作对保障设备安全生产和提高企业管理水平都有重要意义。为克服传统的设备巡检系统的诸多弊端，提高巡检工作的便携性、有效性和加强对企业设备的管理，本文首先对设备巡检系统的需求和目标进行了分析，给出了巡检系统的解决方案，然后开发了一种网络化设备巡检系统。主要工作如下：1．给出了设备巡检系统的总体构架。该设备巡检系统由前台掌上巡检仪和后台设备巡检管理系统两大部分组成。前台主要负责按巡检计划进行巡检，后台主要负责对巡检信息进行分析、管理和发布。2．构建了掌上巡检仪的硬件平台。掌上巡检仪硬件系统主要基于嵌入式系统快速研发平台即X-HYPER255硬件开发平台进行开发，它主要有采集板、主板、液晶屏和触摸屏四部分组成。为提高采集速度及采集性能，硬件系统采用双CPU结构，即采集板和主板上分别有自己的处理器。采集板和主板之间通过串口进行通讯。系统采用了触摸屏和液晶屏显示器分别作为系统的输入设备和输出设备，方便了仪器的操作并大大减小了仪器的体积和重量。为了降低系统的功耗，实现了液晶显示器自动关屏功能。3．结合硬件结构平台的特点构建了掌上巡检仪的软件运行平台。软件系统采用了嵌入式Linux作为其操作系统，利用MiniGUI图形系统为嵌入式系统提供图形支持，具体工作包括：Bootloader下载、Linux内核的移植、文件系统的移植和MiniGUI的移植。运用Linux下标准C语言进行开发了设备巡检软件，该软件主要具有系统管理模块、点检模块、巡检模块、历史追忆模块和数据通信模块五大模块。为了能及时分析现场数据，巡检软件实现了常用的时域、频域信号分析方法。另外，为了方便输入或修改数据，巡检软件实现了数字软件盘功能。最后将巡检软件交叉编译并移植到掌上巡检仪。4．实现了巡检系统的网络化。前台巡检仪与后台巡检管理系统服务器之间采用了C/S模式网络构架，从而实现它们之间的网络通信。后台远程网络功能的实现采用了B/S模式网络构架，最终达到支持远程共享和远程访问的目的。最后，对巡检管理的模式进行了一些分析和探讨。该仪器集数据采集、存储、分析、追忆、通信功能于一体，且具有体积小，重量轻，便于携带，操作方便等特点。它不但可以及时对现场信号进行基本的时域和频域分析，还可以将采集数据通过网络上传到后台。因为前台掌上巡检仪具有分析功能，因此前台可以独立工作。后台巡检管理系统可以对巡检数据进行各种分析、诊断及报表，而且还可以通过WEB查询巡检信息，从而实现对巡检信息的远程访问。更多还原

【Abstract】 Equipment inspect tour is very important for the safety in production and the improvement of the management activities in an enterprise. To overcome the deficiencies of traditional patrol system and increase the convenience and availability of inspection tour and enhance the management of the facilities, the paper analyzes the demands and purposes of the inspect tour system, then presents a solution to inspection system, and develops a networked inspection tour system. The main contents of the thesis are as fellows:1. The main architecture of inspect tour system is presented. The system consists of anterior hand-held patrol device and inspection management system. Inspecting on schedule is the main task of the hand-held patrol device, and the inspection information can be analyzed, managed and accessed from the inspection management system.2. The hardware platform of the portable patrol device is established. The development of the hardware system of the portable patrol device is mainly based on a quick development platform i.e. X-HYPER255 Development Platform for embedded system. It is mainly composed of a data acquisition board, a motherboard, a liquid crystal display and a touchscreen. To improve sampling efficiency, double CPU structure is adopted, i.e. the motherboard has a processor and the data acquisition board as well. The communication between the two boards is serial communication. This hardware system uses touchscreen as its input device and uses liquid crystal display as its output device, which make the operation of the portable patrol instrument convenient and can greatly reduce the size and decrease the weight. In order to reduce the power consumption, the liquid crystal display can power off automatically.3. The running platform for the portable patrol device software is established according to the hardware platform. The software system uses embedded linux as its operating system and uses MiniGUI graphic system as the GUI of the embedded system. The work contains loading Bootloader and transplanting Linux kernel, the file system and MiniGUI. Then the equipment inspect software is developed with the standand c program language under Linux. It is mainly composed of system management model, insepct model, inspect tour model, recalling model and tranportion model. In order to analyze the signals on-site immediately, the common methods of signal analysis in both time domain and frequency domain are provided. In addition, the number soft keyboard is provided for inputting and correcting number. In the end, the inspect tour software is cross compiled and transplanted.4. The networked realization of inspect tour system is competed. The network architecture between the portable patrol device and the sever computer is C/S mode, so the communication of them is realized. And the server adopts the B/S network architecture, so the inspection information and results can be accessed on the internet. Finally, the management mode of inspection is analyzed and discussed.The portable patrol instrument incorporates many functions in a unit, including data acquisition, storage, analysis, retrospection and communication, etc. and it is characterized by structure compactness, light weight, easy portability and simple operation. It both can analyze the signals on-site in both time domain and frequency domain in time, and it also can upload the patrol data to the server. It can inspect independently because of having analysis function. The inspection management system can analyze and diagnose the inspection data by some means, and the results can be reported in report forms, in addition, the inspection information and results also can be accessed through the Web, which means it can be accessed from distance.更多还原
