Fire hazard prevention and safety evacuation system based on BIM

Abstract

The invention discloses a fire hazard prevention and safety evacuation system based on a BIM, and the system comprises a monitoring terminal which is disposed at a monitoring command center; a plurality of temperature sensors which are used for sensing the temperature of a material in a target building, and transmitting the temperature alarm information when the temperature exceeds a safety temperature threshold value; a smoke and dust sensor which is used for sensing the concentration of the smoke and dust, and transmitting the smoke and dust alarm information when the concentration exceeds aconcentration threshold value; and an RFID positioning device which carries out the information communication with the temperature sensors, the smoke and dust sensor and the monitoring command center, so as to synchronize temperature alarm information, the smoke and dust alarm information and the obtained fire position to the monitoring command center, and display the fire position through the BIM. The system can provide accurate position information of a danger source after an accident, achieves the active and quick prevention and execution of the safety evacuation and rescue, and improves the management level of the safety operation of a building.

Description

technical field [0001] The invention belongs to the technical field of building fire prevention and safe evacuation, and in particular relates to a BIM-based fire prevention and safe evacuation system. Background technique [0002] With the rapid development of social economy, the number of public buildings is increasing. In recent years, major fire accidents often occur in public buildings, and most of the serious casualties are in the buildings. In the 1990s, the number of building fires in my country accounted for more than 75% of the total number of fires, and the number of deaths and direct property losses caused accounted for 90% and 85% of the total number of fire deaths and total direct property losses, respectively. The occurrence of fire accidents has greatly threatened and challenged the personal safety and property safety of the people. At the same time, it has also raised many problems to be solved for the research in the field of fire safety. Effective contro...

Problems solved by technology

The occurrence of fire accidents has greatly threatened and challenged the personal safety and property safety of the people. At the same time, it has also raised many problems to be solved for the research in the field of fire safety. Effective control of hidden dangers. Therefore, in order to ensure the safety of personnel in the building, reduce accident hazards, intelligent fire prevention and fire accidents, real-time understanding of the location of the fire source and the location and dynamics of the staff, especially in emergency It is very important to be able to carry out rapid rescue under certain circumstances and guide the safe evacuation of personnel.
