To facilitate the people, but also allows people to experience a new way of shopping. Are introduced in this paper simple vending machines basic control principle and working process, uses the Mitsubishi PLC programming software of the vending machine sales process of programming, and simulated trading simulation on Kingview 6.55. The design mainly realizes the basic function of ordinary vending machine, which comprises a coin accumulation, coin shortage prompted, coin tips, choose to buy goods and automatic billing and other functions. In the design system, only one kind of commodity can be purchased, in order not to have the procedure mistake, in which the design has been more interlocking. The whole function can simulate the transaction in kingview.
