Research On Fire Alarm And Fire Fighting Linkage System

In recent years,the casualties and losses caused by fire accidents in our country almost can not be estimated.It not only threatens people’s personal safety and property security,but also directly brings losses to China’s economy.With the last few years,the economy of our country is developing constantly and rapidly,and the frequency of fire disaster is increasing day by day.Therefore,the status of the fire prevention in the minds of the people can not be shaken,and the requirements for fire control systems are higher and higher,and more and more intelligent.With the rapid development of science and technology,the original fire alarm system can not meet the requirements of the modern construction,the system will replace the traditional fire alarm system therefore has the system and intelligent fire alarm for the people to resist fire disasters,in order to obtain better protection.And this design is aimed at the library such a special building,designed a set of automatic fire alarm and fire linkage systemThis paper first analyzes the fire disaster in China,analyzes the serious consequences after the fire,and puts forward the importance of automatic fire alarm and fire linkage system.And analysis of the current domestic library fire alarm system operating environment,for the library such a special building,to further improve the alarm system.The second chapter introduces the general situation of the project and its characteristics,and introduces the contents and characteristics of fire alarm and linkage installation project supervision.The third chapter analyzes the traditional alarm system,and for its shortcomings and put forward suggestions for improvement,introduced this system will be used and to achieve the various functions,including system framework,control function,self-test function,fault alarm function,shielding function,but also introduces in detail the design plan of the sensor.The fourth chapter in view of the special library building to the design of automatic fire alarm system,from system selection to the circuit layout and function,and select a number of design,considering the safety work of the library,designed centralized alarm control system,fire control system,gas alarm controller fire emergency broadcast system,fire special telephone network system,fire detectors and fire.The fifth chapter is the design of the fire control system,introduces linkage control processes,and according to the process of man-machine interface is designed to maximize the function of the controller,introduces linkage control system in the process,including the software operating environment,operating authority,system settings,alarm event,scene programming and interactive operation.Through many modifications to the site construction,now has achieved relatively good application results.
