Abstract

The invention discloses a double-spherical low frequency electronic label applied to identity identification of an underground pipeline node or an underground cable node. The double-spherical low frequency electronic label comprises a round shell, an elliptical shell and a low frequency electronic label body. The round shell is sealed hollow structure. The round shell is placed in the undergroundpipeline node or the underground cable node. The elliptical shell is the sealed hollow structure. A balancing weight is fixed at the bottom in the elliptical shell, so the elliptical shell is kept ina vertical state, and the elliptical shell is vertically placed in the round shell. The front face of the low frequency electronic label body is upward and the low frequency electronic label body is fixed on the top in the elliptical shell. The low frequency electronic label body comprises a shell, an antenna and a chip. An electronic label detector can read information in a chip through the roundshell, the elliptical shell and the shell of the low frequency electronic label body. According to the double-spherical low frequency electronic label provided by the invention, a direction demand when the low frequency electronic label works normally is eliminated.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a double-sphere low-frequency electronic tag. Background technique [0002] Low-frequency radio frequency tags, referred to as low-frequency tags, have a working frequency range of 30kHz to 300kHz. Typical operating frequencies are 125KHz and 133KHz. Low-frequency tags are generally passive tags, and their working principle is generally the principle of electromagnetic coupling. When transmitting data between the LF tag and the reader, the LF tag must be located in the near-field area radiated by the reader antenna. The international standards related to low frequency tags are: ISO11784 / 11785 (for animal identification), ISO18000-2 (125-135kHz). [0003] Low-frequency tags are mostly used for identification of underground pipeline nodes and underground cable nodes. As we all know, underground pipelines and cables are concealed projects, and their maintenance and repair a...
