Card vending machine working process is as follows: probably the user based on cargo aircraft, put the IC card in the effective range of automat IC card read and write, after confirmed, after the success of the user to purchase goods amount, vending machine Lord controller corresponding aisle motor drive, the goods can be entered to take off in the warehouse, at the same time the trading information, including the card number, date and time of trade, consumption amount will be recorded in the vending machine memory. So according to the characteristics of its vending machine sales of hardware can be divided into two parts: the main module and driving module, drive module mainly includes the control object to be driven, including dc motor, electromagnetic switch, hard ( Paper) The coin machine, liquid crystal display, etc. Main board is mainly used for brush calorie of consumption and user data upload and various control instruction for driven plate. Below IC card under the simple introduction to basic situation. One read, understand and collision of indicators, read distance indicators to identify what test under the antenna and the tag; Collision what to clear label under what arrangement how long finish. Number two, look at reading and writing instruments for antenna ports, according to the application if need more interface to read and write, and pay attention to the communication interface whether to meet the needs of the project. 3, a RFID application system in addition to and read and write about, and tags, antenna, also be label material, by labeling items movement speed, surrounding environment, etc, before the equipment is determined it can simulate the scene test and verify, ensure that the product can meet the application requirements. Simulation cases at the same time the stability of continuous testing equipment, can ensure the long time of stable work. Four, focus on reading and writing equipment frequency range, to see if it meets the project to the frequency of the specification, and learn to read and write device maximum transmitted power and supporting the selection of the antenna if radiation levels. At present, the introduction of wireless networks based on IC payment vending machine has been put into operation, part of the communication data is still in debugging, IC card read-write device, experts say, the system is convenient for maintenance, the system has low cost, extensible function, in the upcoming based on wireless vending machine market has broad application prospects.
