【摘要】：近年来,物联网得到了飞速发展并逐渐应用到各个行业。电梯作为人们日常生活中的重要组成部分,物联网的应用也逐渐向其拓展。在电梯物联网系统中,一个重要的核心部件是物联网网关,其扮演着云平台与电梯管理机构、维保机构、调试人员以及乘客之间交互的中间媒介的角色。电梯物联网网关的性能优劣直接关系到整个电梯物联网系统运行状况。本文对电梯物联网中的关键元素——网关进行了全新设计,使得网关真正做到智能化、模块化并且操作简易化。本文首先从智慧城市的宏观层面讲述了智能化的大背景,对智慧城市的重要组成部分——电梯物联网进行了现状现状分析。针对电梯物联网中的关键部件——网关存在的诸多问题进行了分析,根据分析中总结出的相关问题,提出了本课题的研究内容和目标。其次对电梯物联网系统与网关的基本功能进行了分析。对于电梯物联网系统从基本理念到系统中的各个网络层进行了宏观阐述。对于网关的基本功能,首先对传统的物联网网关的系统组成与数据链路进行了分析并提出了传统方案中存在的问题。针对存在的问题,提出了本文的设计思路。再者对本文的设计重点分布式黑匣子进行了全面设计。从分布式冗余设计和黑匣子模块化设计两个层面对分布式黑匣子进行了细化分析。对分布式网关冗余设计的诸如拓扑结构、数据链路、失效与恢复、故障切换机制进行了针对性分析。对于分布式黑匣子,结合现场应用情况,设计了黑匣子模块化设计的三个有效方案,并分析了三种设计方案的优缺点。随后对电梯物联网智能网关的硬件和软件部分分别进行了详细分析。其中硬件部分给出了关键部分的设计电路与分析,软件部分主要针对分布式设计和黑匣子的自动识别与通讯建立进行了分析设计。最后对本文设计的电梯物联网智能网关进行了测试与现场应用分析,从工程角度分析了该设备的测试过程与应用情况。
[Abstract]:In recent years, the Internet of things has been rapidly developed and gradually applied to various industries. As an important part of people's daily life, the application of the Internet of things has been gradually expanded. In the elevator Internet of things system. An important core component is the Internet of things gateway, which acts as the cloud platform and elevator management organization, maintenance and conservation agencies. The performance of the elevator Internet of things gateway is directly related to the operation of the whole elevator Internet of things system. The key element in the elevator Internet of things Gateway is discussed in this paper. With a completely new design. Make the gateway truly intelligent, modular and easy to operate. Firstly, this paper describes the big background of intelligence from the macro level of the intelligent city. The status quo of elevator Internet of things, an important part of intelligent city, is analyzed, and many problems existing in gateway, a key component of elevator Internet of things, are analyzed. According to the analysis summarized in the relevant issues. The research contents and objectives of this subject are put forward. Secondly, the basic functions of elevator Internet of things system and gateway are analyzed. Basic functionality for gateways. Firstly, the system composition and data link of the traditional Internet of things gateway are analyzed, and the problems in the traditional scheme are put forward. The design idea of this paper is put forward, and the overall design of the distributed black box is given. The detailed analysis of the distributed black box is made from the two aspects of distributed redundancy design and modular design of the black box. For distributed gateway redundancy design such as topology. Data link, failure and recovery, fault switching mechanism are analyzed. For distributed black box, combined with field application, three effective schemes of modular design of black box are designed. The advantages and disadvantages of the three design schemes are analyzed. Then the hardware and software of the intelligent gateway of the elevator Internet of things are analyzed in detail. The hardware part gives the design circuit and analysis of the key part. In the software part, the distributed design and the automatic identification and communication of the black box are analyzed and designed. Finally, the intelligent gateway of elevator Internet of things designed in this paper is tested and applied in the field. The testing process and application of the equipment are analyzed from the point of view of engineering.
