Design And Implementation Of Elevator Traceability Subsystem For National Special Equipment Safety Supervision Service Platform

In recent years,elevator accidents have occurred frequently,causing public panic.As a special equipment that is closely related to people's lives and safety,it is imperative to establish and improve the traceability system.At present,the traditional centralized retrospective scheme has high construction costs,and information may be maliciously tampered with in the collection and storage links.This results in insufficient credibility of the traceability system and a lack of enthusiasm for enterprises to participate in retroactive system construction.The system is based on blockchain technology.The technical solution of the decentralized database Bi chainDB has features such as immutability,high-throughput,large data-class capacity,and rich query functions,and the cost of decentralized solution is lower,which perfectly solves the above problems.In addition,at present,the domestic elevator traceability system is still in the primary stage,and the standards are not uniform.This article also provides a set of coding schemes.The elevator traceability subsystem is based on iOS,Node.js,BigchainDB and other technologies,its core feature is the elevator traceability information registration and traceability information query.The paper begins with the status of the traceability industry,then introduces the research background of the paper and introduces the relevant knowledge background involved in the system.The thesis focuses on the model of the elevator traceability subsystem and the process of business realization.Finally,the system testing situation is introduced.The expectations of the next stage of work are proposed in conjunction with the progress of the thesis and the development of the technology.
