基于CAN网络互联风电控制系统的研究

Research on Wind Power Generator Control System Based on the CAN Network Interconnection

本文提出了CAN网络互联的方法,并以风力发电系统为例对CAN网络互联进行了分析。本文将若干台风机所包含的CAN节点组成一组,形成一个子网,该子网与其他的子网通过局域网进行互连。所形成的局域网又可以通过路由器或网关与Internet互连,这样实现风力发电与其他能源系统数据交换的需求。本文指出直接将CAN节点的应用层与CAN网关的应用层进行互连是一种比较简便的方法,同时也便于各种监管应用软件的设计。

This article provides an interconnecting method among CAN and other type computer network. It gives a practical example of the CAN interconnection network in wind power system. This article points out that several wind power generators can be make a group to form a sub network, which connecting to the LAN via the CAN gateway. The LAN will connect to the Internet via the routers or other gateways so that all the other power system can interconnect with the wind power system. It also points out that the easy way to connect the CAN and LAN through the CAN gateway is to connect them in the application layers. So the Winsock programming method can be applied to it. And it make easy for practice program designing.
