Design And Implementation Of Vending Machine System Based On FPGA

Nowadays,with the rapid development of Internet technology and information,the domestic auto-sale industry is also in a period of rapid development.According to the characteristics of the auto-sale industry,it mainly concentrates in public places,scattered locations,which is not conducive to centralized management and control.Therefore,in such an industry context,the intelligent design of vending machines reflects the great practical application value.The main content of this paper is mainly about the development history and status quo of vending machines,the related technology and development process of vending machines at home and abroad,and the working field and application scope of vending machines.The vending machine control system based on field programmable gate array is introduced.The vending machine control system is designed with VHDL language.The system has the main functions of receiving coin handling,commodity selection,coin refund and change finding,and displaying the amount of money.Through the field programmable gate array design tool ISE,compile and simulate.Through EDA software PROTEL,the hardware system with FPGA as the core is designed,including the design of system implementation principle and hardware circuit.Then,according to the realization of the system,the software flow design and the program implementation design are carried out.Finally,the design and implementation of the system are tested by using the MATLAB simulation software,and the curve of the simulation test and the analysis results are obtained.The vending machine system based on FPGA designed in this paper has finally completed the project design of the whole system,and verified the feasibility of the design scheme,and the results meet the expected requirements.
