A kind of rfid electronic tag device and identification method for petroleum special pipe

Abstract

The invention discloses an RFID electronic label device and an identification method for an oil-specific pipe, belonging to the application technology field of radio frequency (RFID) technology in the field of Internet of Things. An inner preform sheath and an outer preform sheath are connected to the two-port male thread button and the female thread button of the special oil pipe. The outer preform sheath is to protect the male thread port of the pipe, and the cover of the outer preform is just a The RFID electronic label is pasted or inlaid on the cover of the plastic material of the pipe port section; the outer plastic blank is embedded with a thin metal sleeve, and the outermost layer on the concentric circular section is about 10-12mm thick metal ring Surface, the depth of the outer plastic cover is shallower: the depth of the small-diameter pipe is less than 20mm, and the depth of the large-diameter pipe is less than 30mm. For the large-diameter oil special pipe, a shallow rectangular groove is opened in the center of the plastic cover, and the length of the rectangular groove is smaller than that of the outer plastic. The diameter of the blank plastic cover; for the oil special pipe with smaller diameter, a shallow square groove is opened in the center of the plastic cover, and the side length is smaller than the diameter of the plastic cover.

Description

technical field [0001] The invention relates to an RFID electronic tag device and an identification method for special petroleum pipes, and belongs to the technical field of application of radio frequency (RFID) technology in the field of the Internet of Things. Background technique [0002] RFID technology is a non-contact automatic identification technology, which uses radio frequency signals to realize automatic identification of target objects and obtain relevant data. Here, the current object we choose is UHF electronic tags, and one of the factors that affect the reading rate is the intrinsic characteristics of radio frequency. Products such as paper, wood, insulating plastic, and cardboard are translucent to radio frequency; materials containing liquids, especially salty liquids and food, absorb ultra-high frequency (UHF) radio frequency energy; metals and very thin metals The parking chip will make the radio wave deviate from the target and prevent the radio wave fr...

Problems solved by technology

But at present, in the storage management of oil companies, it is mainly the management of 02 materials (petroleum special pipes), that is, the subject matter is metal products, and the only way to achieve a satisfactory reading rate is to use passive metal special tags or customized Metal tags, however, the cost of these two tags is about 10 to 20 times higher than passive ordinary tags

As far as the current Changqing Oilfield is concerned, the annual throughput is about 3.8 million tons, and 1 ton of steel is 5 steel pipes on average, that is, the annual throughput is 19 million. The label cost is too high to engage in this technological innovation ; On the other hand, in the process of entering and leaving the warehouse for special petroleum pipes, regardless of the cost, passive metal special labels or customized metal labels are selected. The location of the label plays a decisive role. Being squeezed and collided, and the second is that the reflected radio waves in the background environment should not be too strong, otherwise the 100% reading rate cannot be guaranteed
