Abstract

The invention discloses an RFID (Radio Frequency Identification Device) Internet of things chip. The RFID Internet of things chip comprises a reader-writer, an RFID chip, a storage, a power supply, an antenna and a radio-frequency field, wherein an RFID card enters the radio-frequency field of the reader-writer; induced current is obtained through the antenna, and is taken as the power supply of the chip through a booster circuit; a digital signal of the induction current is detected through a radio-frequency front-end circuit, and is transmitted into a logic control circuit for performing information process; reply information is obtained from the storage, is returned to the radio-frequency front-end circuit through the logic control circuit, and is transmitted back to the reader-writer through the antenna. The antenna determines the communication channel and communication way between the RFID card and the reader-writer, automatic control and monitoring are realized on a production assembly line by using an RFID technology, the productivity is increased, the production way is improved, and the cost is saved.

Description

technical field [0001] The invention relates to an RFID Internet of Things chip, which belongs to the field of wireless communication. Background technique [0002] Existing RFID IoT chips have the following problems: [0003] (1) The existing RFID IoT chip is difficult to realize automatic control and monitoring on the production line, the productivity is low, and the material cost is wasted; [0004] (2) The existing RFID IoT chip is used in warehouse cargo management, which cannot effectively solve the information management related to the flow of goods, the speed of processing goods is slow, and all information of goods cannot be obtained at any time; [0005] (3) The existing RFID IoT chip anti-counterfeiting technology itself has low requirements and is easy to forge. The cost of the radio frequency card is relatively high. The existing radio frequency card has less memory and has a low capacity to store and modify data related to the product, which is not conducive t...
