【摘要】：随着以设备故障诊断技术为基础的设备管理思想从大型设备逐渐应用到中小型设备的管理中,针对大量而分散的非关键设备,面向设备诊断的点检系统将成为设备管理的主力。本课题结合企业的网络和数据库系统平台,构建网络化的点检系统平台。在分析国内外点检终端仪器的开发基础上,设计了集便携式数据采集以及故障诊断、巡检管理等功能于一体的点检终端。该便携式的点检终端以高性能的ARM芯片为硬件平台,并采用嵌入式linux操作系统作为软件运行和开发平台。课题主要完成了以下几个方面的工作： (?)点检系统构建。分析点检系统功能要求,构建了一种以设备诊断为核心的网络化点检系统,介绍了系统的整体框架和工作流程。 (?)点检终端硬件平台的设计。对点检终端进行功能分析和整体规划,并进行整体的硬件结构设计。以高性能ARM片上系统为中心构建各功能模块,重点设计了人机交互模块(LCD、触摸屏)、电源管理模块以及通信模块。 (?)点检终端的软件系统构建。软件系统主要包括嵌入式linux内核、各外围设备的驱动程序以及基于GUI系统的应用程序。 (?)将射频识别技术应用到基于ARM和嵌入式linux系统的点检终端中,完成了EM4905与ARM芯片的接口电路设计,编写了射频识别的驱动程序。 (?)数据采集模块的开发和研究。重点设计了点检系统的振动数据采集模块以及红外温度测量单元。分析数据采集模块的工作原理,编写了数据采集模块的驱动程序,采用多线程技术开发了数据采集模块的应用程序。
[Abstract]:With the application of the equipment management idea based on the equipment fault diagnosis technology from the large-scale equipment to the small and medium-sized equipment management, aiming at a large number of dispersed non-critical equipment, The spot inspection system oriented to equipment diagnosis will become the main force of equipment management. This subject combines the network and database system platform of enterprise, constructs the network spot inspection system platform. On the basis of analyzing the development of terminal instrument of spot inspection at home and abroad, A portable data acquisition, fault diagnosis and inspection management terminal is designed. The portable terminal is based on high performance ARM chip. And the embedded linux operating system is used as the software running and development platform. The main tasks are as follows:. What? The function requirement of spot inspection system is analyzed, a networked spot inspection system with equipment diagnosis as its core is constructed, and the whole frame and workflow of the system are introduced. What? The design of the hardware platform of the spot inspection terminal. The function analysis and overall planning of the point inspection terminal are carried out, and the overall hardware structure is designed. The functional modules are constructed with the high performance ARM on-chip system as the center. The man-machine interaction module (LCD), touch screen module, power management module and communication module are designed. What? The software system includes the embedded linux kernel, the drivers of each peripheral device and the application program based on the GUI system. What? The RFID technology is applied to the spot check terminal based on ARM and embedded linux system. The interface circuit between EM4905 and ARM chip is designed and the driver of RFID is written. What? ) the development and research of data acquisition module. The vibration data acquisition module and infrared temperature measurement unit of the spot inspection system are designed. The working principle of the data acquisition module is analyzed, and the driver of the data acquisition module is compiled. The application program of data acquisition module is developed by multi-thread technology.
