Research On Key Technologies Of Real-Time Fault Warning For Automatic Material Conveying System

With the development of intelligent discrete workshop material automatic conveying system,it is more complex,automatic,flexible and intelligent.The traditional regular maintenance mode is difficult to meet the needs of system operation and maintenance,which makes the intelligence become the essential trend for the automatic material conveying system.The paper is aimed to R&D real-time fault warning system regarding automatic material conveying system in order to improve the low efficiency and high cost problems,satisfying the demand of real-time fault warning and visualization.Based on IoT(Internet of things)technology,combining with CEP(complex event processing)and VR(virtual reality),the system can implement real-time fault processing and fault visualization,improve the intelligent degree of system maintenance.Firstly,according to the demand analysis,establish the real-time fault warning architecture of automatic material conveying system containing function construction,information integration framework and network topology construction.Furthermore,do researches on two key technologies.One is real-time fault warning technology with CEP and the other is fault visualization technology based on 3D virtual reality platform.On the former one,the system fault mode is divided into several hierarchies and then build the fault hierarchy processing model,according to the analysis of automatic material conveying system function.On the basis,the paper proposes the real-time fault warning approach based on CEP.On the later one,the paper researches on the 3D visualization technologies,proposes the multi-level,multi-particle 3D modeling,virtual scene technology and model optimization technology,realizes the fault visualization.Finally,utilizing an intelligent automatic material conveying system as an instance,validate the innovative technologies and achievements presented in the paper.Meanwhile,the system applies in the automatic electricity meter verification system,which verifies the feasibility and practicability of key technologies.
