The Investigation Of Wireless Communication Protocols Apply To Airport Driving Birds Network And The Implementation With Embedded Software

"Bird-bumped" is an international problem which always puzzles human and imperils the flying safety. Keeping the airspace of airport clearance and minimizing the possibility of bird-bumped is the guarantee of the safety of the aero planes while taking off and landing. At present, the main instrument of low altitude driving birds in airports is simply audio frequency, but after a long time, the birds are used to the sound, whether can we solve the problem is the key factor to driving birds technology.The thesis investigates the present state of driving birds'methods, and designs a set of wireless driving birds network project based on the theory of short distance wireless communication. The project is applied to the hardware flat roof of the new audio CMOS chip and has realized the decoding, error-control coding and mode controlling of data flow in driving birds protocols. Accordingly, the thesis achieves compositive driving birds, availably solves the technical problem. The thesis roots in the Dalian science and technology fund item and the cooperative item of Dalian Maritime University and Dalian Airport. It introduces the backdrop, actuality of the task, detailedly researches a great deal theory of short distance wireless communication, including wireless data transmission model, data link control procedures, error control, researches and discusses wireless communication protocols, expatiate content, actualize project and the result has been testified. The thesis mostly achieves such work as follows:(1) Puts forward a new generation bird driving chip scheme, realizes a new wireless driving birds' terminal and builds the network hardware platform. (2) Researches wireless data transmission technology, data link control procedures, error control and etc. Designs a set of wireless protocol which is suitable for short distance wireless communication to satisfy the diversified requirements of driving birds.(3) Adopts advanced embedded software programming technology, using the wireless network system, and makes the system with intelligence, humanization and better practicability.The wireless communication software of the thesis gains sustain of Dalian science and technology fund, and has applied patent, the system of the driving birds working in Dalian airport gains well effect, radically settles the laggard national driving birds method.
