Abstract

The invention discloses a single-ball low-frequency electronic tag, and is applied to the identification of an underground pipeline node and an underground cable node. The single-ball low-frequency electronic tag comprises a circular outer shell, liquid and a low-frequency electronic tag body. The circular outer shell is a sealed hollow structure, and the circular outer shell is arranged in the underground pipeline node or the underground cable node; the liquid is accommodated in the circular shell body; the front face of the low-frequency electronic tag body is upward floating in the liquid,and the low-frequency electronic tag body comprises a shell, an antenna and a chip. The antenna is circular, and the antenna is sealed in the shell; the chip is horizontally arranged at the central part of the antenna, and the chip is welded on the inside of the shell; wherein an electronic tag detector can read the information in the chip through the shell of the circular outer shell and the low-frequency electronic tag body. Therefore, the single-ball low-frequency electronic tag eliminates the direction requirement of the low-frequency electronic tag in the normal operation, and greatly facilitates the field installation and construction.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a single-ball 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 are...
