With the rapid development of social progress, economic, technological, modern architectures demonstrate the characteristics of large-scale, complex, intelligent and humane. Also, people’s awareness of safety has strengthened. All those lead to higher requirements for building’s fire safety. According to the British statistics on fire casualties causes, the deaths due to carbon monoxide poisoning or other toxic fumes smoked are generally accounted for40%to50%of the total fire deaths. Therefore, to study how people can make safe, accurate and rapid evacuation is of great significance upon fire occurrence.Current national building fire protection design codes have laid strict rules fire detection and alarm systems and evacuation instructions, but they works independently of each other, not to mention performing with close contact and in scientific and rational ways; Also, most of the commonly used evacuation directional signs are with fixed direction, which may lead personnel to the danger zones. Although varying directions evacuation signs are available from domestic manufacturers, they can be realized from the hardware prospective. Taking into account the existing emergency evacuation systems which have difficult in meeting the needs for fire evacuation of modern building and the merits of smart evacuation systems, such as centralized monitoring, collaborative action and dynamic optimization, an smart evacuation systems was developed in this paper and its software and hardware system, and related key issues, especially the optimal path generation algorithm and the upper and lower machine communication protocol were also studied.When fire or other emergency danger occurs, firstly, fire detection and evacuation facilities status information from the centralized monitoring system is input into this system; Subsequently, performing flue gas trend analysis and the evacuation path initial state identification and with the usage of ant colony optimization algorithm, architectural space optimal evacuation paths are generated; Finally, evacuation signs are updated according to the optimal evacuation paths and personnel are safely and balanced guided to the nearest evacuation sites. While in ordinary circumstances, the operating status of evacuation equipment are dynamically monitored with the system and management and maintenance decisions for building emergency evacuation equipment are aided.Overall system hardware design for the smart emergency evacuation instructions, ant colony optimization algorithm for optimal evacuation paths generation and communication design for centralized monitoring systems and evacuation instructions were studied in the paper. Simulations were run to verify feasibility of the smart evacuation and instruction system. Thus, it is of great significance to further extend it to real applications.
