A visual wi-fi radio frequency reader

Abstract

The invention discloses a visual Wi-Fi RF (radio frequency) reader. The reader comprises a CPU (central processing unit), an RF module, a clock module, a power management module, a key module, a Wi-Fi module, an SD (security digital) card and an Eink electronic paper display module, wherein the CPU is connected with the RF module, the clock module, the power management module, the key module, the Wi-Fi module, the SD (security digital) card and the Eink electronic paper display module. A high-performance STM32 is used as a core controller, CC2520 and CC2591 are used as RF chips, an Eink screen is used as a display screen, the Wi-Fi module communicates with external wireless equipment, the visual Wi-Fi RF reader with low power consumption is designed, and tag information can be displayed; all that is required for systematic management of tags is to connect wireless equipment such as a PDA (personal digital assistant) provided with management software with the reader through Wi-Fi, flow type management can be realized, and the trouble of wired connection is omitted; the reader is convenient to use and has broad application prospect in patrol, logistics, inventory management and other fields.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification, in particular to a visualized Wi-Fi radio frequency reader. Background technique [0002] Radio frequency identification, RFID (Radio Frequency Identification) technology, also known as radio frequency identification, is a communication technology that can identify specific targets through radio signals and read and write related data without the need to establish mechanical or optical contact between the identification system and specific targets . At present, RFID technology is widely used in libraries, access control systems, food safety traceability and other fields. [0003] The most important advantage of the radio frequency identification system is non-contact identification, which can read tags through snow, fog, ice, paint, dirt and harsh environments where barcodes cannot be used, and the reading speed is extremely fast, less than 100 milliseconds in most cases. ...

AI Technical Summary

Problems solved by technology

[0005] At present, in the RFID system, the reader basically communicates with the PC through USB / RS232, and the PC controls the reader to realize the tag inventory, identification and information modification, and the user can only view the relevant information of the tag on the PC; Display label information and modify relevant information directly on the reader, there are many inconveniences in practical applications
