Handheld type Internet of Things terminal

Abstract

A handheld type Internet of Things terminal comprises a power control module, a system control module, an external device, an RFID read-write module and a barcode recognition module. The RFID read-write module comprises a low-frequency radio frequency unit, a high-frequency radio frequency unit and an ultra-high frequency radio frequency unit. The power control module is used for controlling power sources of all the functional modules. The system control module is used for processing data collected by the terminal. According to the Internet of Things terminal, based on existing functions, the read-write function for multi-protocol RFID labels under multiple frequency bands is increased, specifically, working under three frequencies including 125 KHz, 13.56 MHz and 915 MHz is supported, and the defect that an existing Internet of Things terminal only supports a single specific label is overcome. The two-dimensional barcode recognition and read function is added, and the defect that an existing handheld Internet of Things terminal only supports an independent RFID function or an independent barcode scanning function is overcome. Low consumption of equipment is achieved through a power management module.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a handheld Internet of Things terminal. Background technique [0002] The Internet of Things is an important part of the new generation of information technology. Its English name is "The Internet of things". Therefore, as the name suggests, "the Internet of Things is the Internet of things connected". Therefore, the definition of the Internet of Things is to connect any item to the Internet for information exchange and communication through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing devices according to agreed protocols. A network that realizes the intelligent identification, positioning, tracking, monitoring and management of items. [0003] With the rise of the Internet of Things, and the development of large-scale integrated circuits, network communications, an...

AI Technical Summary

Problems solved by technology

However, the existing handheld IoT terminals with RFID reading and writing functions only support the reading and writing of specific protocol tags in a specific working frequency band and the extended application on this basis, which has relatively large limitations and a small application range. It is not conducive to the promotion and application of portable readers and the development of Internet of Things technology and industry
