Abstract: After the firefighting reform, it is an important problem for the fire and rescue team to build a modern fire fighting command system that adapts to "all disasters and major emergencies". This paper analyzes the problems affecting the effectiveness of combat command in fire rescue. Then, combined with the overall strategic objectives of the national "14th Five-Year" plan for fire protection, a three zones management and control mode was proposed to divide the disaster site area according to different task division, so as to ensure the maximum effectiveness of standardized and orderly combat. At the same time, information technology and Internet of Things are used to collect data and information of disaster scene and on-site combatants in multiple dimensions, mathematical models and algorithms are used to assist commanders in on-site command and safety management, and relevant data will be classified and displayed on the fire command screen of command, task, data, information and video. In this way, we can give full play to the role of data and information, realize the standardization and order of complex site and scientific command, and finally lay a solid foundation for winning.

Key words: firefighting, command system, three zones and five screens, assisted decision-making, cooperative command
