摘要
基于单总线技术的对讲系统的总体设计方案，对其硬件设计、软件设计及流程进行了阐述．通过解决各分机跟主机间通信线路的共享冲突问题以及主机和各分机之间传输数据的同步等几个关键问题，使该系统能够满足于中、小型医院的病房对讲系统的要求．
An overall protocol of intercom system based on one-wire bus technology is introduced, Its hardware and software design and procedures are discussed. Solutions to some key problems of CDMA and TDMA by SCM in one-wire bus are analyzed in detail. By using the methods of CDMA and TDMA, based on the Single Chip Micyoco （SCM）, a kind of sickroom intercom system is designed. This system has the eharacteristics of simple electric circuit, easy installment, and low cost.
