The invention discloses a method for realizing single-line communication of elevator bus buttons. The method comprises the following steps of: realizing single-bus synchronous real-time communicationby adding a same-in and same-out multiplexing mechanism on software and hardware on the basis of a traditional universal asynchronous transceiving transmitter in a four-line bus connection mode, in asingle-bus link circuit, all equipment are connected in parallel, a host on the software provides synchronization signals for time synchronization between master equipment and slave equipment, data reading and writing are carried out in a TDM (Time Division Multiplexing) transmission mode, and after the method is adopted, the real-time performance of communication is improved, line links are reduced, maintenance is reduced, and the reliability of electrical links of the equipment is improved.

    本发明公开了一种电梯总线按钮单线通讯的实现方法,包括以下步骤:采用4线总线连接方式在传统通用异步收发传输器基础上,通过在软硬件上增加同进同出的复用机制,从而达到实现单总线同步实时通讯,在单总线链接电路中,所有设备之间都是并行连接,软件上主机提供同步信号用于主从设备之间的时间同步,通过时分复用(Time Division Multiplexing,TDM)的传输方式来进行数据的读写,采用上述技术方案后,使得通讯的实时性增加,减少线路链接减少维护,增加设备电气链接可靠性。
