摘要
在一线器件组成的温度监测系统中,通常要求分布于不同位置的多个从机能与主机进行通信,从而实现对监测系统工作状态的监视和控制.若多个从机与主机间的通信采用传统的串口多从机通信方式,不仅硬件开销大,而且增加了程序的复杂程度.本文介绍了一种方案,即主机与从机的通信共享一线系统中的硬件和软件资源,实现基于一线协议的多从机的主从通信,可以很好的解决这个问题.
In temperature measurement system composed of 1-Wire devices,multiple slaves distributed to different positions usually need to communicate with the master to monitor and control the status of the system.If the system uses the traditional serial interface communication mode,it will complicate both hardware interface and software program.To solve the problem, this paper proposes a method that master and slaves share the hardware and software resource with 1-Wire devices to implement communication with slaves based on 1-Wire protocol.
