Method and device for accurately reading and writing integrated circuit (IC) card of handheld equipment in grain industry

Abstract

The invention provides a method for accurately reading and writing an integrated circuit (IC) card of handheld equipment in grain industry. The method comprises the steps of setting echo intensity of an ultra high frequency (UHF) handheld machine; sending an ID reading request to at least one UHF IC card; assembling different UHF IC cards on different vehicles loaded with food; receiving an ID returned from the at least one UHF IC card according to the echo intensity; respectively sending data reading requests to the UHF IC cards corresponding to the IDs with regard to each received ID; binding the ID of the UFH IC card and grain data when the grain data returned from the UHF IC card is received, and performing identification; and respectively performing data writeback on the UHF IC cards corresponding to the IDs with regard to each received ID. A device comprises a setting module, a first sending module, a receiving module, a second sending module and a processing module. By the scheme, the ICs can be accurately read and written by using the UHF handheld machine on the condition of a plurality of cards.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for accurately reading and writing an IC card with a hand-held device in the grain industry. Background technique [0002] Currently, RFID (Radio Frequency Identification, radio frequency identification technology) handsets are applied in a wide range of fields, and can transmit information, confirm information, and the like. Among the RFID handhelds, the more commonly used types are UHF (UltraHigh Frequency, ultra-high frequency) handhelds. The reading distance of UHF handhelds is 0 to 5 meters, so UHF handhelds are generally used in places with high distance requirements, such as In the process of unloading food and other goods. The UHF IC card is used together with the UHF handheld, and the card is divided into an epc area and a user area. Among them, the epc area has an identification function, and the user area has a storage function. In the grain industry...

AI Technical Summary

Problems solved by technology

The above process must be operated on the premise of confirming a UHF IC card or contact operation, but in the case of multiple cards, the UHF handheld can not operate a card alone, but can only perform group reading. Collect the number of UHF IC cards, which brings great inconvenience to users
