The Study And Implementation Of Equipment Lifecycle Management System Based On Internet Of Things

In recent years, the IOT(internet of things) technology has been developing so rapidly that it is widely used in the fields of life, such as smart city and intelligent transportation etc. The most important idea behind IOT technology is to give some equipment life so that we can use these devices to obtain data, achieve control automation, and make economic benefits.This article studies the full lifecycle equipment management based on IOT, using meter reading environment as the case, which contains gas meter, heating meter, water meter, electric meter and gateways. These devices exist in large quantities, require accurate data collection, and have unified communication protocol and some other features that contains key point of equipment management. The traditional device management system collects data manually, which is inefficient, can’t detect faults automatically and repair timely, and also lost its effect when manage instrumentation in larger district or in a larger region.In order to improve equipment management level in meter reading environment, this paper investigated the development of IOT technology, researched equipment lifecycle management theory, studied from device’s spare parts inventory management to ledger management, running management (including data collection, status monitoring), fault management, maintenance management, and then adopted SOA development idea and distributed architecture to design and implement an equipment management system. It has met the basic device management needs and solved all the problems which are emerged in the older model. This paper firstly described related IOT technology and equipment lifecycle management theory, listed the characteristics of all devices in meter-reading environment, and then analyzed system functional needs and Non-functional needs, combined with the current device management status, divided various functional needs into system modules. Secondly, it finished system’s outline design and detailed design, given system’s overall structure, such as physical and logical architecture, engineering organizations, code organization, database design and functional module’s detailed design. Finally, it uses OSGI implemented the system, and finished full system test, painted system’s actual running effects picture. Generally speaking, this system involved multiple stages of instrumentation equipment management, like spare parts inventory, device ledger, running, fault management and repair, achieve the goal of device’s full lifecycle management, it also has been deployed on testing machines, and running well.
