Research On Intelligent Building Fire Monitoring System

After entering the 21 st century,in order to reduce the housing shortage caused by the increase in population,various large-scale buildings such as middle and high-rise buildings and super high-rise buildings are increasing.However,traditional building fire monitoring facilities failed to keep up with the rapid development of modern high-rise buildings due to technical and structural reasons.Traditional wired fire protection has many shortcomings compared to wireless fire protection,such as complicated installation and poor reliability.At present,the replacement of cable with wireless has become an industry development direction in fire monitoring systems.Data is collected by nodes,wirelessly transmitted data,and cloud servers analyze data.This new architecture replaces the original wired data transmission method,making the entire system reliable.Sex,stability and real-time are all important guarantees.In view of the shortcomings of the existing traditional building fire monitoring system,this paper proposes a new intelligent building fire monitoring system design,wireless transmission+Internet of Things way for data transmission.It uses wireless transmission of data instead of wired transmission data,and a local area network is built inside the building by Lora(Long Range).The node end analyzes,processes,collects smoke information and temperature information from the smoke sensor and the infrared camera,and finally sends the result(ie,whether a fire has occurred)to the data concentrator through the Lora,and the data concentrator packs the data.The data is sent to the cloud server through the 4G module,and the server side saves the received data to the database.The administrator can log in to a specific website by accessing the domain name,and can view the indoor fire information in real time on the computer side and the mobile phone side.For the above scheme,the hardware circuit and software program of the system node end and the data concentrator end are designed,the Lora networking is realized,and the obtained fire information is sent to the data concentrator.WAMP(aka Apache,MySQL,and PHP)is installed on the cloud server to manage incoming data and bring websites to the web.In addition,the cloud server also designed a TCP receiving program to receive the fire information sent by the 4G module and save it to the MySQL database.In order to better display the fire information in the room,the cloud server side also designed the front-end login page,the fire information display page and the front-end background management system.The login page only allows the personnel with the account and password to log in,and the front-end background management system is Manage the display of front-end pages,add users,increase the number of floors,and more.Testing of smoke sensors,thermal imaging cameras and the entire system,the system works well and achieves its intended purpose.
