An Integrated Power-Information Networking for the Future Mechatronics System

在集成了制造产品的所有必要过程(如设计、制造、测试、管理等)的CIM系统中，在各种过程中使用的可编程设备和终端应该具有连接到信息网络系统的灵活性，以便在整个工厂环境中实现更高程度的自动化操作。根据这类系统集成的技术趋势，一种称为MAP(制造自动化协议)的标准化通信协议被提出，并正在爆炸性地推广。为了充分利用这条便捷的通信路径进行工厂生产操作，应在每个独立终端和可编程设备中提供智能通信功能。与工厂环境相比，通信功能已经在基于计算机的系统中得到了很好的发展，并在办公室环境中得到了很好的传播。在工厂地板上，…更重要的是，机电一体化控制系统，如数控机床、机器人系统、物料搬运和输送系统，都可以被认为是“信息-功率转换器”，应该具有智能通信功能，才能实现自动化工厂的安全、高效运行。由于目前的控制器采用基于软件的功率控制以及基于分布式微处理器的控制部件的信息处理，因此在信息-功率转换过程中以及在常规的信息-信息处理中都可以获得关于系统内状态的有价值的信息。以便有效利用机电一体化控制中可用的各种信息。这项研究旨在为未来的机电系统开发集成功率处理和信息处理的小区域联网系统的必要技术。介绍了网络系统的概念，讨论了系统的关键技术，提出了系统的硬件和软件体系结构，并对系统进行了可行性研究，并对系统的原型进行了描述。较少

In a CIM system, which integrates all necessary processes such as design, manufacturing, testing, management, etc., for manufacturing a product, the programmable devices and terminals used in the various processes should have the flexibility of connection to an information network system for higher degree of automated operation over the total factory environment. In accordance with the technological trends in this sort of system integration a standardized communication protocol called as "MAP (Manufacturing Automation Protocol)" has been proposed and is on the way for explosive dissemination. In order to fully utilize this convenient communication path for productive plant operation, intelligent communication functionality should be provided in each stand alone terminals and programmable devices. The communication functionality has been well grown up in the computer based systems and well disseminated in the office environment compared to the factory environment. On the factory floor, … More especially, mechatronics control systems such as CNC machine tools, robot systems and material handling and transfer systems, which can be considered as " information-power converters", should have the smart communication functions so that a safe and productive operation of an automated factory can be realized. Since the recent controllers are adopting software based power control as well as information processing with a distributed microprocessor-based control components, the valuable information concerning in-system status can be obtained in the information-power conversion process as well as in the regular information-information processing. In order to facilitate the effective utilization of the various information available in the mechatronics control. system, the concept of "In-system networking" or "small area networking" can be introduced both for power handling and information processing.This research has been established aiming at development of necessary technologies for a small area networking system which integrates power handling and information processing for the future mechatronics systems. We introduced a concept of the network system, discussed key technologies for the system, proposed the architecture of system hardware and software and described the results obtained in the feasibility study which had been performed by prototyping the system.
