CANopen在交通绿波带控制系统中的应用

Application of CANopen Protocol in Green Wave Control System

CAN总线技术由于其优越的链路层性能,近年来得到广泛应用,CANopen是一种CAN应用层协议标准。介绍了如何将CANopen规范移植到交通绿波控制系统中,描述了CANopen应用的关键-对象字典的建立,并介绍了实现绿波带控制的通信机制。

This article describes a solution of green wave control,and gives a strategy to achieve of the green wave control.The control network base on CAN bus technology and CANopen application protocol,and the article describes the core of the CANopen,the object dictionary,and introduced the green wave control＇s mechanism of communication.
