摘要
鉴于目前基于RS-485通信的监控系统的一些问题,本文阐述了用微控制器P87C591和现场总线技术实现基于CAN总线的监控系统,还详细说明了RS-232与CAN总线转换器和基于CAN总线的云台控制器的硬件、软件的设计。通过分析得出该监控系统的特点,并指出其可推广应用于其它测控领域。
According to the problems in the supervisory system based on RS-485, this paper discusses how to use the mic-rocontroller P87C591 and the technology of Field bus to realize the supervisory system based on CAN bus. The design involves RS-232-CAN protocol converter and dome controller about both hardware and software in detail. This paper also analyzes the characteristics of the design and indicates that it can be introduced into other measuring and controlling field.
