Wireless Sensor Networks In Building Fire Safety Technology

Be with the development of the city, the fire detection system has become to be one of the necessary systems of a building. The buildings have become more and more complex because of the using purpose and the environment, with the development of several decades, the fire detection systems, nowadays the fire detection systems are composed with double-lines systems. In some special buildings, the normal fire detection systems can't be used because uncertain reasons. So it's necessary to develop the WSN (Wireless Sensor Network) fire detection system in order to protect the special buildings.The WSN systems is the new result of the communication technology, being with the development of the WSN systems, it has be used in many areas just like military area,environment area and so on. The development of WSN systems has leaded a good result in the foundation design of HS (Hardware Structure), CP (Communication Protocol) and the SR (Net-systemize Rule). The fast development of WSN can offer the technology condition to develop the WSN fire detection system.The application of the WSN in fire detection technology was based on the development of WSN. Nowadays, the fire detection technology area had become to be one of the applied areas. In this paper, we design a WSN fire detection system based on one-jump, two-rank and three-level structure. The sink point was a normal point in normal fire detection system and it also receive the data coming from the 1st rank points, and the 1st rank points finish the missions like monitor the protecting areas , receive the data coming form the 2nd rank points and send the data to sink sensor point. The 2nd rank points monitor the areas and send the data to the 1st rank point. The one-two-three structure WSN system can finish the mission of protecting the area and give out a alert.The energy supplying is a difficult problem for WSN system and the fire detection system need to monitor the environment continually; it's one of key problems for the application of WSN systems that is the supplying of energy. In a WSN system, offering much more energy and inducing the wastage of the system are both the important problems for the development of WSN technology.
