1、双CAN总线高速环形网络的结构设计我们这里提到的硬件结构设计平台其实是指工控机以及作用在PCI总线基础上的CAN接口卡,这里面所有的卡带都具备两个CAN连接总线处,它们之间的每一个都能够单独完成运作。在网络的设计环节里面通过主要结构以及从属结构的通讯形式,并且在网络内部所有的从属站点互相也能够完成对话连接。在这里面,主要站点具备两个CAN连接总线出,所有的从属站点都具备一个CAN接线处。对于软件的设计这项工作来说,是通过VISIUAL C++6.0这项技术来完成 1, double CAN bus high-speed ring network structure design We mentioned here refers to the hardware design platform in fact refers to the IPC and the role in the PCI bus based on the CAN interface card, where all the cassette has two CAN connection bus , Each of them can work alone. In the design of the network through the main structure and subordinate structure of the form of communication, and all subordinate sites within the network to each other to complete dialogue and connection. In this, the main site has two CAN connection bus out, all subordinate sites have a CAN connection. For the design of the software work, is done through the VISIUAL C + +6.0 technology
