摘　　要：针对传统电梯群控通讯系统存在通讯线路过多,稳定性较差,电缆多引起的高成本、高故障率的问题,将无线通讯技术应用到电梯群控通讯中。开展了电梯群控系统结构与工作原理的分析,并以STM32W108芯片为核心的Zig Bee无线模块作为每台电梯主控板的群控模块,建立了各电梯群控模块之间的通讯关系及过程,通过用Keilu Vision4软件编写通讯程序、搭建试验平台,设计了一种电梯无线群控通讯系统。并通过波形图上所显示的数据帧的时间间隔验证了通讯的可靠性。研究结果表明,相比于传统电梯群控通讯技术,本系统的设计在保证了通讯正常的前提下,不仅提高了通讯的稳定性,而且减少了电缆的使用,对现有的群控通讯技术的发展具有重要的现实意义。Aiming at the problems of too many communication lines, poor stability, high cost and high failure rate caused by using many cables in traditional group control elevator, the wireless communication technology was investigated to elevator group control communication. After the analysis of structure and working principle of the group control system, the ZigBee as a group control module of every elevator＇s main control board while the STM32W108 chip as the core of it, communication relationship and process between one group control module and the other group control module were established. By programming which was wrote by the KeiluVision4 and building a test platform, a wireless group control communication system was designed to elevator. Through the waveform graph data frame of time intervals, verified the reliability of communication. The results indicate that compared with traditional elevator group control communication technology, This system design under the premise that guarantees the normal communication, not only improves the stability of communication, but also reduces the use of cable, there is an important practical significance to current group control the development of communication technology.
