RFID rapid inventory method

Abstract

The invention relates to an intelligent vending machine technology and provides an RFID rapid inventory method to solve the problems that when there are many goods in a vending system at present, a main controller needs to perform duplication eliminating processing in a large amount of label data, which increases the amount of data transmitted and processed by the system, prolongs the inventory time of the vending system and reduces operation real-time performance of the vending system. The main points of the technical scheme are that the main controller detects door opening / closing signals atevery moment; if a door opening signal and a door closing signal are detected once within the specified time, name call information is sequentially sent to a sending point of each electronic tag oneby one according to an electronic tag list stored in a local database; if response information of all the electronic tags is received, no processing is performed, otherwise it is recorded that goods corresponding to the electronic tags which do not respond to the information have been sold out, and then it is judged whether the data information of the electronic tag responding to the information is consistent with the data information of the electronic tag corresponding to broadcast. If the data information of the electronic tag responding to the information is consistent with the data information of the electronic tag corresponding to broadcast, the electronic tag list stored in the local database is updated.

Description

technical field [0001] The invention relates to the technology of intelligent vending machines, in particular to the technology of RFID fast stocktaking of goods. Background technique [0002] Self-service vending machine is a common equipment for commercial automation. It is not limited by time and place, can save manpower and facilitate transactions. It is called a 24-hour miniature supermarket. At present, the use of self-service vending machines in China is becoming more and more common, and has been widely used in stations, subway stations, office buildings and other places. [0003] RFID is radio frequency identification technology, commonly known as electronic tags. RFID radio frequency identification is a non-contact automatic identification technology. It activates the chip in the electronic tag through radio frequency signals, and the chip returns radio frequency signals to automatically identify the target object and obtain relevant data. RFID technology can ide...
