摘要：A wireless vending machine system based on the GSM network is developed in this paper. First of all, several methods by which we may realize wireless data communication of GSM network are analyzed and compared, the overall structure of vending machine system based on USSD is given an in-depth introduction. Furthermore, control modules which realize data transmission and control function of terminal device, middleware which connects application and BOSS (business operation support system), and transaction software embedded in USSD platform, are also developed respectively. Finally, the operating support system of wireless vending machine system is formed, which can not only integrate vending machines, USSD platform and payment system together, but also manage sale information, logistic information and consumer information on-line. The vending machine system presented in the paper has been put into use in several provinces and cities for more than two years. All performance indexes of the system are satisfying.
