Research On Application Of Intelligent Gas Supervision System Based On Node.js + Express Frame

Based on the business development needs of gas equipment company,this paper adopts advanced IT software technology to develop the integrated intelligent gas monitoring system of business,data and management.The overall framework of the system is based on the node.js platform,which is built using the Web application framework--Express architecture.The system adopts the hierarchical model: The presentation layer is based on Web server and adopts technologies such as HTML5 and CCS.The design of UI platform is more conducive to the development of supervision;The business logic layer is developed in the JavaScript language.For easy development,Express can organize the server-side JavaScript into testable,maintainable modules;The data access layer uses MySQL,an open source database management system,to provide reliable data persistence support.This paper also modulates the system functions,including five parts: map overview,abnormal alarm,report summary,user feedback,and system management.At present,the system has been able to achieve many basic functions,such as the normal display and switching of UI pages;Ajax technology to realize real-time data interaction;The theme-based MQTT protocol can communicate normally;User management;Basic information display and management of RTU;The basic presentation of real-time data and historical data;Conditional generation and export reports,and so on.In addition,the system page display and jump function is normal,and the performance of real-time data interaction can meet the requirements.
