An Integrated Power-Information Networking for the Future Mechatronics System

在集成了设计、制造、测试、管理等生产过程的CIM系统中，各个过程中使用的可编程设备和终端应具有连接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发展趋势，提出了一种标准化的通信协议“制造自动化协议”（MAP, Manufacturing Automation protocol），并正在迅速传播。为了充分利用这一便捷的通信路径进行工厂的生产操作，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，通信功能在基于计算机的系统中得到了很好的发展，并且在办公环境中得到了很好的传播。特别是数控机床、机器人系统、物料搬运搬运系统等机电一体化控制系统，作为“信息-力量转换器”，应具备智能通信功能，实现自动化工厂的安全生产运行。由于目前的控制器采用了基于软件的功率控制和基于分布式微处理器的控制组件的信息处理，因此在信息功率转换过程和常规的信息信息处理过程中，可以获得有关系统内状态的有价值的信息。为了便于有效地利用现有的各种信息进行机电一体化控制。系统中，可以引入“系统内联网”或“小区域联网”的概念，用于电力处理和信息处理。本课题旨在为未来机电一体化系统开发集电力处理和信息处理于一体的小区域网络系统所需的技术。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架构，并描述了通过系统原型进行可行性研究的结果。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.
