| Modern buildings have high internal complexity,and when a fire occurs,it is difficult to evacuate people at the scene.However,most of the buildings in China use non-centrally controlled systems,which lead to the inability to centrally control the fire emergency lighting to indicate the evacuation direction for the site personnel in case of fire,reducing the success rate of personnel evacuation.For the shortcomings of the non-centralized control system,the study of centralized control type fire emergency evacuation system has important engineering significance.The research content of this paper is as follows:(1)For fire equipment control and fire emergency evacuation,a set of fire emergency lighting and evacuation management system software was developed to meet the national standard and practical requirements,and the emergency evacuation and escape logic was designed.The software is based on the national standard for demand analysis,structured design and communication design of the system,the software has user management,parameter setting,terminal management,status detection and other modules,can access the equipment of a number of smoke alarm manufacturers for fire linkage,in the event of a fire can be triggered by the escape logic of the fire area fire indicators indicate the direction of escape,effectively guide people to evacuate safely.(2)For fire equipment control and fire emergency evacuation,a set of fire emergency lighting and evacuation management system software was developed to meet the national standard and practical requirements.The software is based on the national standard for demand analysis,structural design and communication design of the system,the software has user management,parameter setting,terminal management,status detection and other modules,can access the equipment of many smoke alarm manufacturers for fire linkage,in case of fire can be developed by their own escape logic to trigger the fire area fire indicators to guide people to evacuate safely.(3)In order to verify the feasibility of the system,the system functionality and non-functional performance of the fire emergency lighting and evacuation management system software were tested in a residential district in China in combination with supporting hardware facilities.The test results show that the performance of the management system is in line with the expected design objectives and meets the needs of fire emergency lighting and evacuation management in the community. |
