摘要

本文研究了一种将移动机器人和自动导引车(AGV)等移动设备连接到现场总线的方法。本文采用IEEE 802.11无线局域网对移动设备的Profibus-DP网络进行扩展。为了实现这两种网络的集成，设计了一种协议转换器，该转换器由Profibus-DP协议的主进程和IEEE 802.11协议的虚拟主进程两个进程以及传输缓冲区组成。此外，为了满足数据通信的实时性要求，在协议转换器上开发了虚拟轮询算法。

Integrated network of Profibus-DP and IEEE 802.11 wireless LAN with hard real-time requirement

This paper focuses on a method to connect mobile devices such as mobile robots and automated guided vehicles (AGV) to a fieldbus. In this paper, the IEEE 802.11 wireless LAN is used to extend a Profibus-DP network for the mobile devices. In order to integrate these two networks, a protocol converter is developed that consists of two processes-master process of Profibus-DP and virtual master process of IEEE 802.11-and a transmission buffer. Furthermore, a virtual polling algorithm is developed at the protocol converter in order to satisfy real-time requirements on data communication.
