目前大多数AI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,本文论述了基于神经元芯片MC143150和单片机AT89S51双处理器结构的AI节点的硬件和软件的设计过程。文章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。
At present, most AI nodes only have a single neuron processor, and its control ability is not high. In response to this situation, this article discusses the design process of the hardware and software of the AI node based on the dual-processor architecture of the neuron chip MC143150 and the AT89S51 microcontroller. The article introduces the data acquisition system using ADC0809 analog-digital conversion chip, the interface of AT89S51 and MC143150 and the interface of MC143150 and physical network in terms of hardware. The paper introduces the data acquisition, parallel slave A mode communication and the use of network variables to send information Three aspects of programming.
