Abstract

The invention discloses a target location and tracking system based on a low-frequency electromagnetic wave. The target location and tracking system comprises a transmitting terminal, a receiving terminal and a server, wherein the transmitting terminal is fixedly arranged at a specific position and is used for transmitting the low-frequency electromagnetic wave, the receiving terminal is fixedly arranged on a target and is used for receiving the low-frequency electromagnetic wave and figuring out the strength of the low-frequency electromagnetic wave through analogue-to-digital conversion, and the server figures out the distance between the transmitting terminal and the receiving terminal according the strength of the low-frequency electromagnetic wave transmitted by the transmitting terminal and the strength of the low-frequency electromagnetic wave received by the receiving terminal, combines the distance between the transmitting terminal and the receiving terminal with the position of the transmitting terminal, and locates and tracks the target. The invention further discloses a target location and tracking method based on the low-frequency electromagnetic wave. By means of the target location and tracking system and method based on the low-frequency electromagnetic wave, the problem that a traditional location system is inaccurate or even is out of work in location when barriers exist is solved, and a wide range of location requirement of the system can be met through a system expansion method.

Description

technical field [0001] The invention relates to a positioning and tracking system, in particular to a target positioning and tracking system and method based on low-frequency electromagnetic waves. Background technique [0002] Positioning technology is changing every aspect of human life. The application of the GPS system has entered the life of ordinary people, and various derivative applications of car navigation, GPS positioning map and GPS emerge in an endless stream. However, due to the limitations of its own system, GPS cannot be used in buildings. Moreover, the positioning accuracy of civilian-grade GPS is poor, and it is not suitable for small-scale precise positioning applications. As a result, many indoor and small-scale positioning systems have appeared in the market. These systems use various forms of signals for positioning, such as ultrasonic signals, infrared signals, 433MHz electromagnetic wave signals, 900MHz electromagnetic wave signals, 2.4GHz electroma...
