【摘要】 随着现代工业的飞速发展和生产规模的不断扩大,对企业生产自动化和各种信息的集成要求越来越高。面对国内外激烈的生产同行的竞争,加之业务发展的内在需求,实施以ERP结合现场总线控制系统为核心的信息化建设是目前急需攻克的战略课题。ERP分布式管理控制系统以它的高可靠性成为用户解决方案的首选,近几年来以实时分布式系统为基础的现场总线技术也已成为自动化领域的热点之一。本文分析了在信息时代,生产管理系统作为企业资源计划系统的重要组成部分,能够保证生产计划的科学性、预见性、准确性和采购的及时性、合理性、经济性,可以大大提高企业的管理水平,提升企业的竞争力。因此,对企业ERP生产管理系统进行研究具有非常重要的意义。本文根据分布式系统分散控制集中管理的特点,在研究了PCI总线的基础上,设计了一种PCI-CAN通信适配卡,用以完成管理层到现场控制层的通信功能,制定了CAN应用层通信协议,完成了相关的Windows驱动程序的设计。最后完成了管理层的系统软件设计,从硬件和软件方面完成了整个分布式管理系统,实现企业的控管一体化。实验证明采用ERP与现场总线技术相结合得生产线管理系统后,控制精度高,动态响应快,并可应用在负载变动大,动态响应要求快的应用系统。更多还原

【Abstract】 With modem industry and its scale soaring, automation and information integration of enterprise production should be improved. Distributed control system is one main contributor to customer solutions in terms of the high reliability. More focus is given to field bus technology based on real-time distributed control system in the automation community these days. In the frequency conversion and timing system of AC induction motor, it is hardly to be comparable with DC if only employing U/F and open loop control to solve smooth adjusting and can not meets the needs of the application system which have high desire on the dynamic and static capability.During the information era, the rapid development of information technology represented by network technology brings great impact and challenge to the traditional manufacturing industry. So the information-based manufacturing is the only way of the development of manufacturing industry. This is the idea firstly presented in this dissertation.Considering the features of distributed control system, studying PCI bus, one kind of PCI-CAN communication adapter is designed out to connect management layer and field control layer. CAN application layer protocol is determined. Communication control algorithms and drivers for Windows are developed.Software of management layer is implemented to control and manage Multi-motor controller directly. The motor control system is implemented in terms of the software and hardware.Verified by filed tests, distributed motor control system based on DSP and field bus has high control accuracy, fast dynamic response, and could be applied for some systems where loads change largely or dynamic response should be fast.更多还原
