The Design And Implementation Of The Third Party Logistics System

Be with the development of the city, the fire detection system has become to be oneof the necessary systems of a building. The buildings have become more and morecomplex because of the using purpose and the environment, with the development ofseveral decades, the fire detection systems, nowadays the fire detection systems arecomposed with double-lines systems. In some special buildings, the normal firedetection systems can’t be used because uncertain reasons. So it’s necessary to developthe WSN (Wireless Sensor Network) fire detection system in order to protect the specialbuildings.The WSN systems is the new result of the communication technology, being withthe development of the WSN systems, it has be used in many areas just like militaryarea、environment area and so on. The development of WSN systems has leaded a goodresult in the foundation design of HS (Hardware Structure), CP (CommunicationProtocol) and the SR (Net-systemize Rule). The fast development of WSN can offer thetechnology condition to develop the WSN fire detection system.The application of the WSN in fire detection technology was based on thedevelopment of WSN. Nowadays, the fire detection technology area had become to beone of the applied areas. In this paper, we design a WSN fire detection system based onone-jump, two-rank and three-level structure. The sink point was a normal point innormal fire detection system and it also receive the data coming from the1strank points,and the1strank points finish the missions like monitor the protecting areas, receive thedata coming form the2ndrank points and send the data to sink sensor point. The2ndrankpoints monitor the areas and send the data to the1strank point. The one-two-threestructure 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 detectionsystem need to monitor the environment continually; it’s one of key problems for theapplication of WSN systems that is the supplying of energy. In a WSN system, offeringmuch more energy and inducing the wastage of the system are both the importantproblems for the development of WSN technology.
