摘要
针对目前电梯控制系统中存在的通讯线过多,导致电梯运行的稳定性降低、所需电缆较长、成本较高、故障率高等缺点,提出了一种新的通讯方案,对相关的问题进行了分析,并给出了硬件设计和软件编程。
A new communication design is given in this paper to resolve such problems as less stability, too long communication cable, high cost, high malfunction rate and so on caused by using too many communication lines in elevator control system. The relative problems are discussed as well as the hardware design and software program are given.
