In view of the present situation of the high-rise building fire hidden danger monitoring is improper,the fire discovery is not prompt and the rescue is not prompt,this article proposed one kind of fire detection alarm(including the early warning)system design scheme based on Internet of things.The system can detect,early-warning,alarm and spray the fire by using sensor detection technology,single-chip microcomputer control technology and Internet of things technology.The concrete realization process is: STM32F103C8T6 is used as the main control chip,selects ESP8266 communication module to connect the wifi,establishes the communication with the Server.Through analyzing and processing the information of smoke,temperature and humidity,CO sensor,temperature and humidity,CO concentration and flame intensity collected by smoke sensor,temperature and humidity sensor and infrared flame sensor,the infrared tube collection escape channel is occupied and the RFID module monitors the storage of the fire fighting facilities.The final node end processing result is sent to the cloud server through the Wi Fi communication module,the database stores the results received by the server.Users can use the computer or mobile phone to log on the designed web page and view the fire information monitored by the node end,which realizes the high efficiency and real-time fire alarm.This paper first introduces the Intelligent fire-fighting system based on Internet of things,and then,according to the problems existing in the current fire detection system,on the basis of adding IOT technology,this paper puts forward the whole scheme of fire detection and alarm system based on Internet of things,and expounds the fire detection and alarm system in detail from two aspects of hardware and software design.Secondly,the neural network and the model and theory are connected in parallel as the characteristic layer of the fire detection and Early Warning Algorithm.Using Matlab to carry on the simulation to two kinds of algorithms,and puts forward the final decision-making judgment according to two kinds of results.The decision-making judgment of the algorithm is only used to display on the web page for users to view and take preventive measures,not as the judgment basis for starting fire alarm.Then using the structure of HTML + CSS + JS + PHP + MYSQL to design the server-side alarm platform,and realize the functions of data display,storage and analysis,users can view the real-time data detected by the sensing device and the fire probability,you can also view fire equipment storage,duty personnel information and adjust the spray valve start mode(manual/automatic).At last,the system is compared with a 3C fire detector on the market,and the system test and fire data collection are completed,which proves that the system can help the rescue and evacuation of high-rise fire. |
