基于RAM共享的多分支电梯CAN总线

A Multi-embranchment Elevator CAN Bus Structure Based Sharing RAM

随着通讯技术的发展,现场总线技术已广泛应用于电梯控制系统。本文简要介绍了国内外较流行的CAN总线技术的特点,针对电梯控制系统总线的特点,通过共享RAM的设计理念,引入了多分支的CAN总线结构,使电梯控制系统在保证高速数据通讯的基础上,结构更灵活,扩展更方便。

With the development of communication technology,field bus technology is broadly applied in elevator control system. Considering the characteristics of the elevator control bus,the article has introduced a multiembranchment CAN bus structure based on the sharing RAM theory,it ensures the high speed communication within the elevator control system,makes the structure flexible and easy to extend.
