The Design And Implementation Of Intelligent Bus POS

IC cards are going further into people's daily life because of its convenience as small pay,including bus,library,stores,etc.Bus POS(Point Of Sales),one of the most important terminal for IC card,provides the basic guarantee for the small pay.With the continuous development of information technology and electronic techonology,the bus POS also suffers from update and changes.Today,the bus POS has characteristics of long time,multiple solution,trade and version,which can be hard to achieve unification.The concept ‘intelligent bus' has put forward higher requirements on the performance of the bus POS.Based on the current situation of the bus POS development,this paper proposes a new bus POS solution.Firstly,we analyse the requirements of the power module,the RFID module,the wireless transmission module,the external memory module,the LCD module and so on,carry on the feasibility,and explain the implementation of circuit,and finally determine the hardware selection.Then,according to the functional requirements of the POS,we define the software framework and give the logic of how to realize the key operation,RFID operation and the data transmission operation.Finally,based on the popular third-party payment,we put forward the prospect for bus POS JiSao yards,and simply expound the hardware framework and software realization process.The paper finally designed a new type of bus POS,which support IC consumption,the transaction records upload,remote program update,terminal information query,etc,improve the hardware performance and the program process,making people'stravelling more convenient.
