Abstract

The invention discloses an anti-theft locating and tracking system. The anti-theft locating and tracking system comprises a locating device and a tracking device, wherein the locating device is arranged on an article, the tracking device is held by a user, the locating device comprises a first ARM processor, a first beidou navigation chip, a first circularly polarized antenna, a first GPRS chip, a first linearly polarized antenna, a second linearly polarized antenna, an FM emitting chip, a first accelerometer gyroscope chip, a sound alarm and a power module; the tracking device comprises a second ARM processor, a second beidou navigation chip, a second circularly polarized antenna, a second GPRS chip, a third linearly polarized antenna, a fourth linearly polarized antenna, an FM receiving chip, a second accelerometer gyroscope chip, a touch liquid crystal display screen and a power module. The anti-theft locating and tracking system integrates far-distance beidou navigation locating, a middle-distance radio direction finding locating, and small-distance moving state and alarm sound locating, and can achieve theft preventing, locating and tracking in various complex environments.

Description

technical field [0001] The invention relates to the field of location tracking, in particular to an anti-theft location tracking system. Background technique [0002] Existing anti-theft positioning and tracking systems can only rely on positioning modules and alarm sounds to find lost items. However, the positioning module has inherent accuracy errors, and when it is blocked by obstacles such as walls, the positioning accuracy is extremely poor and even the position data disappears. If the lost item is placed in a building or basement, it is difficult for the user to approach it even if it can be approached through the positioning data. Get the specific location of the item very accurately to find it. Moreover, in crowded and noisy places, it is impossible to simply rely on hearing to find lost items. Therefore, when using the existing anti-theft positioning tracking system, it is difficult for the user to really find the lost item. Contents of the invention [0003] T...
