关于电梯远程监控系统与电梯之间通用通讯协议的研究

Development of Common Protocols for Communications between CCMS and Elevators

由于目前电梯远程监控系统还处于比较封闭的阶段,每个电梯厂家都有自己专有的通讯协议,协议的不开放性导致只能由电梯厂家自己开发监控系统。本研究的主要目的是定义电梯数据的统一格式,然后将其转化为通用协议,提供给监控软件厂家一个通用的接口,便于上层监控系统的二次开发。本研究针对目前世界上的通用协议,选择了XML、BACnet、LonWorks作为转换的目标对象。本文阐述了电梯数据格式的定义、转化的思路方法及转换后的通用协议带来的好处。

Due to Elevator Remote Central Control and Monitoring System （CCMS） is closed to the public at present, every manufacture develops its own CCMS and has its own proprietary protocols. The main theme of this research is to develop a set of common protocols that can help to transmit information related to the operation of lifts and be understood by both of the elevator and IT industries. Under this system, information of any elevator system can be exchanged with any CCMS in one or all of three standards, namely XML, BACnet and LonWorks. The protocols and a prototype trial system are discussed in this article together with an evaluation on the advantages of implementing such protocols.
