Wireless energy collection type GB/T29768 national standard internet of things label

Abstract

A wireless energy collection type GB/T29768 national standard internet of things label disclosed by the present invention is applied to the radio frequency identification field, adopts a wireless energy collection mode to supply power, realizes a internet of things label satisfying a GB/T29768-2013 national standard ultrahigh-frequency RFID protocol, collects the energy simultaneously via three wireless energy collection schemes of the solar energy collection, the GSM900 frequency band radio frequency energy collection and the GSM1800 frequency band radio frequency energy collection, enables the energy collection time of a system to be shortened substantially, supplies an enough working voltage to the system, and guarantees the reliable operation of the system. The internet of things labelof the present invention can realize the long-distance communication of the active label, also overcomes the disadvantages that the active label is short in service life and needs to replace a battery frequently, and can satisfy the requirements of the wireless sensor network label nodes for the low power consumption and continuous work.

Description

technical field [0001] The invention belongs to the field of radio frequency identification, and in particular relates to a wireless energy collection Internet of Things tag technology that meets the GB / T29768-2013 national standard ultra-high frequency RFID protocol. Background technique [0002] In recent years, radio frequency identification technology (RFID) has developed rapidly. In order to promote the development of domestic RFID industry, my country has independently defined the GB / T29768-2013 agreement. The national standard UHF RFID protocol has independent intellectual property rights in parts such as codec and command structure. [0003] The Internet of Things technology is triggering a new industrial revolution. The Internet of Things technology integrates network, RFID technology, information technology and wireless sensor technology. A wireless sensor network (Wireless Sensor Networks, WSN) is a distributed sensor network, and its nodes can perceive sensory i...

AI Technical Summary

Problems solved by technology

The disadvantage of the prior art is that the battery power supply of the active tag is limited, and the battery needs to be replaced frequently

Passive tags cannot actively initiate communication, and provide few functions, and the communication distance is short, so it is difficult to meet the intensive work requirements of wireless sensor networks

Most of the sensor nodes implemented by RFID technology adopt the ISO / IEC18000-6C protocol, without independent intellectual property rights, and the communication protocols are completely open. The encryption algorithm usually increases the cost and communication efficiency, and it is easy to attack the communication without encryption.
