| 摘 要： | 目前大多数LON节点只具有单一的神经元处理器,其控制能力不高。针对这一现状,该文论述了利用单片机AT89S51设计开发基于主机LON节点的硬件部分和软件部分。在硬件方面介绍了采用ADC0809模数转换芯片的数据采集系统、AT89S51和MC143150的接口及MC143150和物理网络的接口;在软件方面介绍了数据采集、并行Slave A模式的通信和利用网络变量发送信息三方面的程序设计。 |

| Abstract: | Most LON nodes only contain a single processor of Neuron chip currently,so its control ability is not very strong.In view of this,the paper introduces the hardware and software design on LON node using dual processors based on MC143150 and AT89S51.In the aspect of the node hardware,the paper describes the data acquisition system based on ADC0809,the interface of AT89S51 and MC143150,the interface of MC143150 and physical network;In the aspect of the node software,program designs are discussed,including three aspects of data acquisition,parallel communication based on the model of slave A,information transmission using network variables. |
| Keywords: | neuron chip microcontroller LON node design of hardware and software |
