Neuron芯片在变电站自动化系统中的应用

Application of Neuron chip in substation automation system

在分层分布式变电站综合自动化系统网络中,现场总线和与其相连的每个节点间必须要经过用于驱动信道媒介的网络收发器和用于接口的神经元芯片Neuron。Neuron芯片是LonWorks技术的核心,内部包括了3个CPU系统,共同承担着ISO规定的开放系统互联7层协议的功能。文章介绍了美国公司推出的Neuron芯片的功能特性,给出了基于现场总线LonWorks的变电站自动化系统结构框架以及Neuron芯片的连接电路。

In the net of hierarchy and distributed substation synthetic automatic system, between the field bus and the nodes monitoring data must pass through the network transceiver used to drive channel media and the Neuron chip used as interfaces. Neuron chip is the kernel of LonWorks technique, it includes 3 CPU systems, and they take on the function of Open System Interconnection protocol of seven layers prescribed by ISO. The function and characteristic of the Neuron chip produced by American company are introduced in this paper. The framework of substation automation system based on field bus of LonWorks and the linking circuit of Neuron chip are described.
