低压配电系统向网络化管理,一体化协调方向发展,传统的基于主机的节点不能适应这种发展,该文提出了基于神经元芯片的方案。它采用神经元芯片和电能计量芯片实现,较好的解决了这个问题。在节点的开发中,着重介绍了神经元芯片3150与电能计量芯片SA9904B以SPI方式通信进行电参数采集的方法。同时对利用浮点函数进行电参数的计算及网络化通信基础的网络变量的设计也进行了较详细的论述。
Low-voltage distribution system to the network management, integrated coordination direction, the traditional host-based nodes can not adapt to this development, this paper proposes a neuron-based chip program. It uses a neuron chip and energy metering chip, a better solution to this problem. In the development of the node, the method that the neuron chip 3150 and the energy metering chip SA9904B communicate by SPI to collect the electrical parameters is emphatically introduced. At the same time, the use of floating point function for the calculation of electrical parameters and network communications based on the design of network variables are also discussed in more detail.
