Design And Development Of Automatic Smoke Alarm System

Smoke poses a great threat to human life safety and living environment.Smoking in public places is harmful to the health of others.As a prelude to fire,smoke is also a subject of fire management.Creating a good living environment and a safe market operating environment puts urgent demands on smoke control in public places.Total smoking bans and firefighting in public places face problems such as large number of active groups,irregularities in places,weak fire safety awareness,lack of fire safety knowledge,and lack of safety hazard inspections.In addition,improper deployment,use and management of fire fighting equipment also requires the strengthening of public places.Fire safety management.Therefore,This paper presents the research on the construction of smoke detectors and smoke fire safety management systems in public places..This thesis first puts forward the background of the construction of the smoke warning system and the smoke fire safety management system,points out the important role of system construction,and summarizes the current status of relevant research at home and abroad.Then the demand analysis of the system is carried out,the feasibility of the construction of the smoke warning system is discussed,and the system design scheme is proposed.The basic requirements of the construction of the smoke fire safety management system are analyzed from the business process,functional use cases and non-functional requirements.Through the flow chart and program coding method,the hardware and software design of the smoke alarm system smoke detector module,smoke sensor and digital-to-analog conversion module are designed,and the hardware diagram of the hardware is realized.The article focuses on the design and implementation of the smoke fire safety management system.The overall system architecture,technical architecture and network topology are designed.The system function structure,function modules and database are designed in detail,and the system function modules are coded.At the end of the article,the hardware and software tests were carried out on the smoke alarm system,and the data integrity test,function test and performance test were carried out on the smoke fire safety management system.Through testing,the system can be released for online operation and deployment to public places.The smoke warning system studied in this thesis uses the single-chip AT89S52 as the control core.The smoke concentration of the surrounding environment is collected by the smoke sensor MS5100.After the smoke concentration simulation data is obtained,the digital information is obtained by the AD conversion chip ADC0832,After comparing with the threshold value in the single-chip microcomputer,an early warning or alarm is carried out to achieve effective monitoring of the smoke situation in public places.At the same time,the smoke alarm is connected to the smoke fire safety management system,through system data monitoring,it helps public market participants to improve fire safety awareness,improve the management level of safety equipment and safety activities,and effectively prevent and eliminate the disaster caused by smoke fires.
