Design And Implementation Of Bird Repelling System On Airfield

Research on repelling birds on airfield has never stopped since the first bird crash happened in the world.With the development of science and technology,combining repelling birds with technology has become a new research trend.The traditional system of repelling birds has the disadvantages of single device,low degree of automation,repelling birds randomly,etc.It does not meet the requirements any more.Therefore,the development of high-availability,automatically controlled system of repelling birds is inevitable.At the same time,the dissertation not only optimizes the deployment of equipment but also proposes a strategy.It can greatly improve the efficiency of the work about repelling birds and ensure all flights are safety.First of all,the dissertation analyzes the functional requirements and performance requirements of the system based on the actual situation of an airport.It has a general design of hardware and software of the system according to the requirements.Secondly,aiming at the problem of automatic confirmation of birds,an algorithm for recognizing birds is proposed and it is proved by experiments that it has a high accuracy.Simultaneously,it increases the degree of automation.Then,in order to deploy equipment rationally,the dissertation analyzes the performances of equipment and transforms the deployment of equipment into an optimization problem of regional coverage.Also,system deploys the equipment according to the performances,and two deployment methods are proposed.Then dissertation compares two methods and selects the most suitable deployment method for the system based on the sound coverage and the number of equipment.In order to accomplish the function of strategy of repelling birds,multiple levels are proposed according to the deployment method of the equipment.The logic of strategy of repelling birds is proposed,which provides a theoretical basis for the generation of decisions in the system.Finally,the dissertation introduces the design of the system in some details.It includes the module of interface,data communication,data processing,implementation and other aspects.The system proves to be feasible by experiments and has a certain value of promotion.
