Design And Implementation Of Fire Protection And Maintenance APP Based On HTML5

Fire protection is an important guarantee for the production and operation of various units in the country,and fire maintenance work is a prerequisite to ensure the normal and stable function of the fire protection system.Regular and effective fire maintenance measures can detect hidden dangers early,ensure the normal use of fire protection facilities,and reduce the loss of personnel and property that may result from fires.In recent years,the number of maintenance services has gradually increased,as a result,the scope of maintenance engineers has expanded.However,the traditional fire maintenance management system has been unable to meet the current business needs.By analyzing the development status of fire management platforms at home and abroad,this thesis designs and implements a management system for maintenance engineers in the fire protection work for the complex supervision and execution of fire protection work.The entire standardized process has been implemented,from the issue of fire protection and maintenance tasks,to the maintenance engineers reviewing and receiving tasks,and then to executing and submitting tasks.At the same time,it guarantees effective user interactions of the system in actual application scenarios.The main work of the thesis is as follows:(1)Demand analysis.According to the maintenance needs of maintenance engineers,the analysis will be carried out and analyzes specific functional points as well as connections between the following four modules: task delivery,task reception,task execution,and task viewing.In the requirements analysis of each module,the Unified Modeling Language(UML)modeling is used to explain in detail,and the use case table is used to perform a more in-depth analysis of each use case.Finally,the non-functional requirements of the system are analyzed according to the system's usage scenarios.(2)Design and implementation.Based on the analysis of the advantages of HTML5 crossplatform and the user experience,the system architecture diagram was drawn.The mobile client uses the HTML5 Hybrid APP development model and APICloud middleware to build cross-platform mobile applications.The server uses the Express framework of Node.js as the basis and the routing system provided by the Express framework for data distribution.By analyzing system requirements,identifying the entities in the system,designing the database in detail,describing the physical table structure in each database,and explaining the meaning and type of each field in the table,the implementation of each important functional module of the system is explained in detail.(3)System test.After completing the system's coding work and test case design,the test environment is deployed in the laboratory and each functional module in the system is tested in detail according to the test cases,meanwhile,the non-functional requirements of the system are tested.After the system testing,the functional logic of the system is processed correctly and the performance can meet users' demands.All functions in the APP are running normally after launching and the page display operates properly which is capable of meeting user needs.In summary,the fire protection and maintenance APP can meet the needs of managing the daily work of maintenance engineers.
