Study On Intelligent Evacuation Sign

Many high-rise buildings have sprung up in the city due to the fast- developing economy of our country. People living and working in these tall and quiet buildings can enjoy the better light and clean air. Therefore, high-rise buildings are very popular in today's highly effective and fast pacing society. In addition, high-rise buildings occupy less construction land, thus increasing green areas.Although high-rise buildings make our life more convenient, they still have many disadvantages: People's lives are threatened because new building materials and products which catch fire easily are widely used. What's more, the complicated internal building structure causes much more difficulties to fire fighting and it is not easy to evacuate people inside in event of a big fire, especially people in some buildings for public use, because they come from different places and know nothing about the structure of the building. In such situation, they will get lost easily if there are no indicatory signs showing them the way out. Therefore, indicatory signs play an important role in guiding people to escape from fires without wasting a lot of time and being hurt.This thesis is intended to introduce an intelligent indicatory sign with the single chip as its system core. The indicatory sign is connected with a fire alarm from which it can get linkage alarm information directly. The indicatory sign works closely with the fire alarm on fire site changes and chooses the evacuation direction according to the information it has obtained.
