Researching And Designing Of Gas Alarm System Based On Laravel Framework

In this paper,the laravel framework is used to study the gas alarm system in detail.Laravel framework(hereinafter referred to as "framework")is an open-source framework under the PHP language environment.PHP is mainly used for the development of network service applications.The language implements a class library by encapsulating various properties and methods,and inherits or rewrites some functional units by using various class libraries.This is a typical object-oriented development mode.The framework has a set of built-in eloquent orm.It can be used to deal with the database simply and intuitively.Through the standard built-in interface,it can effectively prevent some vulnerability risks such as SQL injection.All eloquent models are inherited from the model base class of the framework,and can be created and managed by simple command line.Database migration can also be made convenient and fast by using it,including reverse routing,reverse controller,restful control The function modules,such as device,make the function development under the framework more smooth and elegant.This paper uses these characteristics of the framework to design and implement the key functions of the system.Combined with the advantages and disadvantages of the gas alarm system,a stable and efficient framework is constructed.Gas leakage monitoring is an important part of gas safety operation.In this project,the detector,controller,linkage module and actuator are used to form a field closed-loop control system.The modern Internet of things technology is used to monitor the environmental gas concentration in real time.The data server receives the data uploaded on site.The framework provides services such as authority certification and data interface for various business needs,and designs them separately The routing system,distributed architecture and anti false alarm unit are designed to meet the requirements of high concurrency and reliability of data.Meanwhile,the content distribution network and access acceleration technology are used to ensure users’ fast request response.The goal of this project is to design and realize a real-time monitoring gas concentration gas alarm system,which can meet the requirements of millions of data concurrency and high reliability.It has a good human-computer interface for users,with the functions of real-time monitoring,data mining,false alarm prevention,early warning and decision-making.It can cooperate with different field equipment to realizethe gas alarm monitoring service in industrial and civil environment.In order to verify the actual performance of the system,the subject carried out data concurrency test,function test,compatibility test and safety test,and analyzed the test results in detail.Through the results,the gas alarm system realized in this subject can meet the requirements of the actual operation of the gas alarm monitoring needs,and achieve the expected design goals.
