Design And Research Of Remote Intelligent Fire Monitoring And Automatic Alarm System

With the improvement of family living standards,the number and type of electrical appliances used in mankind has increased significantly,and the electricity load has gradually increased,leading to frequent fire accidents during peak hours.According to the existing "building design fire safety requirements" requirements,the type of building in accordance with the fire level,in addition to personnel-intensive or civil construction public places should be designed automatic fire alarm system,the rest of the site is not mandatory design,in this case if a fire,Timely detection and fire prevention measures can lead to unpredictable losses.Therefore,the design of a suitable for home,small office area,such as the installation of automatic fire alarm system is not necessary.This paper focuses on the design of a remote monitoring,control,alarm timely and simple structure of the remote fire alarm and control system.The system set parameter monitoring,fire alarm,remote control function as a whole,to achieve remote fire alarm and control.Firstly,the traditional fire automatic alarm system and the fire linkage system are analyzed,and the design purpose and demand are put forward.Secondly,the hardware selection,circuit design and software part of the design system are described in detail.The system consists of the acquisition side and the remote control terminal,the acquisition side takes the STC89C51 chip as the core;the remote control end adopts the Andrews smartphone as the carrier.In order to achieve the communication between the two,the system uses ESP8266 WIFI module and server data wireless transmission.Inaddition,the acquisition system also includes MQ-2 smoke sensor and DHT11 temperature and humidity acquisition module,LCD1602 liquid crystal display module,A / D conversion module and relay drive module;remote control terminal mainly includes Andrews environment software design.The system has many advantages compared with the existing products,mainly embodied as follows: First,the traditional fire automatic alarm system according to the specification requirements,the installation scope is more limited;and the system can be based on the needs of the owners,installed in the family or old residential area And other small fire alarm system can be used for wireless transmission,but the distance is short,and must be in the same LAN;and the system uses WIFI(hereinafter referred to as WIFI),and the traditional fire alarm system is generally wired transmission,a few remote fire alarm system can be wireless transmission,but the distance is short,and must be in the same LAN;Module and server data interchange,remote remote monitoring and control.Through the research and experiment,the system can meet the fire parameters remote monitoring,fire alarm and mobile phone remote control needs,to achieve the purpose of this design.
