The hardware part of this design includes temperature control parts, goods drive part, goods selection and information display section. Temperature control parts including temperature measurement, temperature control two parts, the temperature measured by copper resistance for temperature measurement, can measure the temperature of the inside and outside of the warehouse, witch will be a control signal , temperature control part using small pressor and electrical heating tube as actuators, which is used for temperature control requirements in the appropriate temperature. The goods drive part will based on the utput signal of PLC drive the goods move to the output mouth. Goods selection and information display part adopts keys and LED lights display mode, mainly used for customers some sales information display and lets the user based this information to choice these goods. These buffer circuit are connected with Siemens series S7200 PLC CPU 224 XP CN. The configuration control part of vending machine was used force control for programming. Configuration interface including login page, monitoring interface, alarm inquiry, data curve. By monitoring the configuration of the operation, the staff can understand the vending machine, and the working conditions as well as the historical data of alarm inquires look. And the force control software is Inter publishing functionality, through the Inter can be released, relevant staff can check the sales information in any one working puter.
