Design And Development Of Ticket Vending Machine Based On Smart Subway

With the introduction of the concept of smart city,smart subway is expected to emerge.In this era of rapid development of Internet,artificial intelligence and big data,how to apply emerging technologies to subway transportation has become the focus of attention of the industry.At present,speech recognition is one of the more mature technologies among these technologies,and the introduction of intelligent speech into subway has reached a consensus in many cities.Based on the actual situation of subway station development at the present stage,it is the most practical and ideal solution to use the voice recognition technology in the Ticket Vending Machine(TVM).As a key research object of terminal equipment in subway stations,TVM should adapt to the trend of The Times and become a typical representative of intelligent terminal in smart subway.Voice ticketing function has become the key research content of TVM.Based on the voice reform project of Nanjing Metro ticket machine,this thesis firstly expounds the research status of intelligent subway,Automatic Fare and Collection(AFC)system and TVM at home and abroad.Secondly,the demand analysis of intelligent metro TVM is discussed in detail and the overall design is carried out from the aspects of software structure and work flow.Then it analyzes the difficulties and requirements of voice module access from the physical level and carries out the necessary auxiliary structure design,and then carries on the interface design from the software level.After the voice module is successfully accessed,the object oriented idea is used to design and implement the voice ticket function using C++ in the Visual Studio 2015 environment.In the end of this thesis,a comprehensive system test is carried out on the TVM with voice ticketing function.Through the analysis and comparison of test results,this project meets the expected requirements.
