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。
As the current elevator remote monitoring system is still in a relatively closed stage, each elevator manufacturers have their own proprietary communication protocol, the agreement is not open led only by the elevator manufacturers to develop their own monitoring system. The main purpose of this study is to define a unified format of elevator data and then convert it into a universal protocol to provide a common interface for monitoring software manufacturers to facilitate the secondary development of the upper monitoring system. In this study, XML, BACnet and LonWorks are selected as the target of conversion for the current universal protocols in the world. This article describes the definition of the elevator data format, the conversion ideas and methods and the benefits of the converted universal protocol.
