Wireless radio frequency identification system and method for controlling the active radio frequency identification tag

Abstract

The present invention provides a wireless radio frequency identification (RFID) system. The wireless RFID system includes at least one passive RFID tag, at least one active RFID tag and at least one sink apparatus. The active RFID tag transmits a wireless query signal to detect whether the passive RFID tag and / or other active RFID tags are in its scanning range according to a transmission specification. Moreover, the active RFID tag collects the detecting result into an inventory data, converts itself to one passive RFID tag, and transmits the inventory data to other active RFID tags utilizing the same method. Then, an identification data in the passive RFID tag and / or the inventory data in the active RFID tag are read by the sink apparatus according to the above-mentioned transmission specification. Therefore, the wireless RFID only uses a signal transmission specification to route the data back to the sink apparatus.

Description

technical field [0001] The invention relates to a radio frequency identification system, in particular to a radio frequency identification system which only needs to support one transmission standard. Background technique [0002] With changes in global economic concepts and shopping consumption, the marketing channels of large retail channels such as convenience stores, mass merchandisers, and large department stores have undergone tremendous changes in recent years. The main reason is that the marketing channels of large-scale retail channels have been gradually simplified from the multi-layer and complex channels between manufacturing, wholesale, warehousing, and retail points to the operation mode of manufacturing through logistics centers to each retail point. [0003] Most of the large-scale retail channels at the present stage use radio frequency identification (Radio Frequency Identification, RFID) system to effectively improve the efficiency of warehousing and logis...

AI Technical Summary

Problems solved by technology

[0006] 1. In terms of time considerations, the traditional radio frequency identification system 110 must support two transmission specifications (for example: class-1 generation-2 formulated by the EPC standard and the transmission specification formulated by zigbee), so additional time must be spent, and the The stack specified by class-1 generation-2 is repackaged into the stack specified by zigbee

[0007] 2. In terms of power considerations, the traditional RFID system 110 must spend extra energy on the conversion of the stack

[0008] 3. In terms of cost, each reader in the traditional RFID system 110 must have two sets of hardware devices to implement two different transmission specifications

Correspondingly, the system cost will also increase accordingly

[0009] 4. In terms of compatibility, zigbee and z-wave are still competing with each other, so it is impossible to predict what the final dominant transmission specification will be

In contrast, no matter whether the traditional radio frequency identification system 110 adopts the transmission specifications formulated by zigbee or z-wave, it may face the dilemma that it cannot be applied in the future
