摘　　要：为增强LonWorks技术控制音频信息的能力,设计了基于SPCE061A单片机和MC143150神经元芯片的LonWorks节点。阐述了SPCE061A单片机和MC143150神经元芯片的功能特点,分析了节点中SPCE061A与MC143150两处理器之间串行接口的设计,接口通过硬件握手协议避免了数据的丢失;节点的软件部分给出了节点对音频数据采集和处理的程序流程图,对相关寄存器的设置进行了介绍,并给出了利用Neuron C语言中的io-changes事件、IO对象、IO库函数和网络变量将节点采集到的信息发送到LonWorks网络上。实验表明节点通信性能良好。In order to enhance LonWorks technology control capability of audio information, LonWorks node based on mierocontroller SPCE061A and Neuron chip MC143150 was designed. Functional characteristics of SPCE061A and MC143150 were described. Serial interface of LonWorks node between SPCE061A and Neuron chip MC143150 was designed, which avoided data loss by hardware handshake protocol. In node software part, the program flowcharts of LonWorks node based on information acquisition and processing for audio were introduced, and the settings of interrelated registers were presented. It was given that information collected by node was tranmitted to LonWorks network using io_ changes event, IO object, IO library function and network variable in Neuron C language. The results of experiment showed that LonWorks node had excellent performance
