The QR-Code-Based Power Plant Equipment Repair And Maintenance Management System And Its App

The author works in a thermal power enterprise and is responsible for the power plant equipment management,routing inspection and maintenance together with his colleagues.As the deep development of plant informatization construction,though the plant has deployed monitoring management system and other information system to implement the equipment management informatization,but there are still unsatisfactory conditions.For instance,it is not fully consistent with the daily equipment routing inspection work flow,the KKS code identification equipment operation is complicated while its efficiency is not high,and it isn’t involved in the advanced mobile internet technology implementation equipment,spare parts and human effective recognition and so on.Regarding to above problems,after the deep communication with company leaders and colleagues and comprehensive analysis for equipment routing inspection and maintenance flow,a power plant equipment repair and maintenance management system,which is fit for the plant actual situation,is designed and implemented.And a suitable app application is also developed following the system.At first,this system has realized the equipment management,on this basis,it also has the maintenance and routing inspection management functions.When implementing equipment management function,it combines QR code technology with KKS code to code the equipment,so it could identify the equipment quickly and accurately and further achieve the equipment adding,state changing,inquiry statistics and maintenance log.When making spare parts management,QR code technology is also used to code the spare parts.The repair and maintenance personnel receives tasks from system by App to implement the planned and unplanned repair and maintenance,in addition,they could get the equipment name,model information and the name & quantity of the needed spare parts by scanning the equipment’s QR code.When doing routing inspection,it could realize the supervision for repair and maintenance personnel works though GPS locating their positions.Firstly,the paper focus on the demand analysis of this system and then turns to the design.This paper introduces the system design philosophy,describes the software architecture design and overall process design,and expounds its function design and data sheet design.Then implementing the system,this paper introduces the system development environment and key technology,and describes detailed implementation procedure of every function module.After system implementation,this paper makes a detailed test for system and App by writing test cases and modifies problems found in tests,finally,the system passes all tests.The implemented power plant equipment repair and maintenance management system in the paper has achieved power plant equipment & spare parts basic information management,planned and unplanned repair and maintenance management and equipment routing inspection.It realizes the quick but accurate recognition for equipment and spare parts in terms of QR code technology,and the supervision for workers by using GPS.The system work flow is not only scientific but also reasonable,which is suitable for the actual condition of this plant.The further job objective for this paper is researching how to integrate the Internet of Things into the system to better realize equipment repair and maintenance management.
