Special high-temperature and high-pressure RFID (radio frequency identification device) tag for oil field

Abstract

The invention provides a special high-temperature and high-pressure RFID (radio frequency identification device) tag for an oil field. The tag comprises a basic material, a chip, a feed line and an antenna receiving / transmitting surface, wherein one surface of the basic material is the front surface of the electronic tag; the other surface of the basic material is an antenna grounding surface; the antenna receiving / transmitting surface on the front surface of the electronic tag is connected with the antenna grounding surface on the rear surface of the electronic tag through a short-circuit groove to form a microstrip antenna; an anode of the chip is connected with the antenna receiving / transmitting surface through the feed line; the grounding end of the chip is connected with the antenna grounding surface on the rear surface of the electronic tag through a through hole; and the tag is packaged by a secondary package material of a housing. The tag has the advantages of small size, long reading distance and strong adaptive capacity to the environment.

Description

technical field [0001] The invention relates to an electronic device, in particular to a tag for radio frequency identification technology. Background technique [0002] RFID (Radio Frequency IDentification) technology, also known as electronic tags and 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 a mechanical system or optical contacts. 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. The sketching capability of active RFID systems is also an important advantage. It can be used for interactive services such as process tracking and maintenance tracking.

Problems solved by technology

[0003] Disadvantages of current RFID: Although the current RFID tags can meet the identification requirements in general harsh environments, they cannot meet the high temperature, high pressure, vibration, chemical corrosion, metal, oil pollution, etc. and their harsh identification in the oil field industry. For special needs, it is necessary to develop a new type of special label with high temperature and high pressure resistance, corrosion resistance and metal resistance
