【摘要】：隨著制造企業(yè)生產(chǎn)規(guī)模的擴(kuò)大，對(duì)生產(chǎn)資源的優(yōu)化配置和生產(chǎn)成本控制越來越受到企業(yè)和學(xué)術(shù)界的關(guān)注。生產(chǎn)設(shè)備作為制造企業(yè)最重要的生產(chǎn)資源之一，呈現(xiàn)出部署位置分散、種類多樣的特點(diǎn)，對(duì)生產(chǎn)設(shè)備實(shí)施網(wǎng)絡(luò)化實(shí)時(shí)動(dòng)態(tài)管理成為企業(yè)生產(chǎn)設(shè)備管理的迫切需求。但生產(chǎn)現(xiàn)場(chǎng)大多數(shù)設(shè)備并不支持以太網(wǎng)通訊，難以接入企業(yè)管理網(wǎng)絡(luò)，導(dǎo)致企業(yè)不能對(duì)生產(chǎn)設(shè)備進(jìn)行實(shí)時(shí)有效管理。 簡(jiǎn)單網(wǎng)絡(luò)管理協(xié)議(SNMP)是專門為實(shí)施網(wǎng)絡(luò)化管理而設(shè)計(jì)的Internet網(wǎng)絡(luò)管理協(xié)議，其采用的管理站(Manager)——代理(Agent)網(wǎng)絡(luò)管理框架能夠?qū)Ψ荌P的生產(chǎn)設(shè)備進(jìn)行網(wǎng)絡(luò)化管理，由于SNMP代理負(fù)責(zé)與現(xiàn)場(chǎng)設(shè)備進(jìn)行實(shí)時(shí)信息交互，其性能直接影響著SNMP管理系統(tǒng)的結(jié)構(gòu)和管理成本。因此，本文在分析生產(chǎn)設(shè)備管理對(duì)SNMP代理需求的基礎(chǔ)上，提出基于Linux構(gòu)建面向生產(chǎn)設(shè)備管理的嵌入式SNMP代理，并重點(diǎn)研究了嵌入式代理構(gòu)建中的引導(dǎo)程序、嵌入式Linux操作系統(tǒng)和SNMP委托代理實(shí)體三個(gè)關(guān)鍵技術(shù)。 首先，在分析U-Boot啟動(dòng)和通用性實(shí)現(xiàn)原理的基礎(chǔ)上，設(shè)計(jì)嵌入式SNMP代理引導(dǎo)程序功能，基于此研究了U-Boot移植中的關(guān)鍵問題；針對(duì)U-Boot不支持大容量Nandflash啟動(dòng)和不能兼容兩種Flash啟動(dòng)方式的問題，在不改變U-Boot通用性的前提下，對(duì)U-Boot進(jìn)行了改進(jìn)，增強(qiáng)U-Boot的兼容性。 其次，，根據(jù)生產(chǎn)設(shè)備管理對(duì)嵌入式SNMP代理的需求，對(duì)Linux內(nèi)核進(jìn)行了移植和圖形化的定制；在分析Linux設(shè)備驅(qū)動(dòng)原理的基礎(chǔ)上，依據(jù)應(yīng)用系統(tǒng)設(shè)備配置屬性，移植了LCD和DM9000網(wǎng)卡設(shè)備驅(qū)動(dòng)，設(shè)計(jì)觸摸屏輸入和RS485設(shè)備驅(qū)動(dòng)程序；結(jié)合嵌入式Linux各種文件系統(tǒng)的特點(diǎn)和應(yīng)用系統(tǒng)硬件配置，設(shè)計(jì)了多文件系統(tǒng)架構(gòu)，并研究了實(shí)現(xiàn)中的關(guān)鍵問題以及圖形支持系統(tǒng)Qt/Embedded的移植。 最后，建立了面向生產(chǎn)設(shè)備管理的SNMP委托代理模型，重點(diǎn)對(duì)模型中擴(kuò)展MIB庫、協(xié)議映射器、設(shè)備通信管理器進(jìn)行了研究，并詳細(xì)設(shè)計(jì)了委托代理模型初始化、請(qǐng)求服務(wù)響應(yīng)、生產(chǎn)設(shè)備監(jiān)管等工作流程。在對(duì)系統(tǒng)進(jìn)行集成的基礎(chǔ)上，搭建模擬系統(tǒng)，對(duì)代理各部分功能和整體進(jìn)行了測(cè)試。
[Abstract]:With the expansion of production scale of manufacturing enterprises, more and more attention has been paid to the optimal allocation of production resources and production cost control. As one of the most important production resources in manufacturing enterprises, production equipment has the characteristics of scattered deployment and diverse types. It is an urgent need for enterprises to implement networked real-time and dynamic management of production equipment. However, most of the equipments in the production site do not support Ethernet communication, and it is difficult to connect to the enterprise management network, which results in the enterprise unable to manage the production equipment in real time and effectively. Simple Network Management Protocol (SNMP) is a network management protocol specially designed for the implementation of network management. The management station (Manager) -agent (Agent) network management framework can manage non-IP production equipment networked. Because SNMP agent is responsible for real-time information exchange with field devices, its performance directly affects the structure and management cost of SNMP management system. Therefore, on the basis of analyzing the demand of SNMP agent for production equipment management, this paper proposes to build embedded SNMP agent for production equipment management based on Linux, and focuses on the bootstrap program in embedded agent construction. Embedded Linux operating system and SNMP proxy entity three key technologies. Firstly, based on the analysis of the principle of U-Boot startup and universal implementation, the function of embedded SNMP agent boot program is designed. Based on this, the key problems in U-Boot porting are studied. In order to solve the problem that U-Boot does not support large capacity and can not be compatible with two flash startup modes, U-Boot is improved without changing U-Boot generality to enhance U-Boot compatibility. Secondly, according to the requirement of production equipment management for embedded SNMP agent, the Linux kernel is transplanted and customized graphically. The device driver of LCD and DM9000 network card is transplanted, the touch screen input and RS485 device driver are designed, and the multi-file system architecture is designed according to the characteristics of embedded Linux file system and the hardware configuration of application system. The key problems in the implementation and the porting of QT / embedded, a graphic support system, are studied. Finally, the SNMP principal-agent model for production equipment management is established, and the extended MIB library, protocol mapper and device communication manager are studied, and the principal-agent model initialization and request service response are designed in detail. Production equipment supervision and other work processes. Based on the integration of the system, the simulation system is built, and the function and the whole of the agent are tested.
