摘要
介绍了采用神经元芯片对 A/ D转换器和双端口 RAM进行控制的数据采集与监控系统的硬件实现与软件设计。通过消息在基于 L on Works现场总线的节点间通信 ,将采集节点采集的数据通过网络双绞线传送到中央节点 ,存入双端口 RAM,上位机根据需要可读出数据 ,显示于监控界面。
The hardware implementation and software design of neuron chip based data acquisition and monitoring system,which can control A/D converter and dual port RAM,are described.The LonWorks based nodes communicate with each other through the messages.Data collected from collecting nodes are sent to the central node via network twisted pair wires,and stored in the dual port RAM.Data can be read and displayed by control PC on the monitoring interface when necessary.
