Description

Technical Field

[0001] The utility model belongs to the technical field of antenna positioning, and in particular relates to a LoRa-based intelligent antenna positioning system. Background Art

[0002] LoRa is a low-power, long-distance wireless communication technology. The main features of LoRa wireless communication technology are:

[0003] (1) Long distance: In dense urban environments and cities, LoRa has strong penetration capabilities, and its data transmission distance can reach more than 3 km; in open suburbs, its transmission distance can reach 15 km to 30 km, or even farther.

[0004] (2) Low cost: The cost of LoRa terminal sensors is low.

[0005] (3) Low power consumption: The LoRa protocol is developed specifically for low power consumption, and the battery life can reach several years.

[0006] GPS positioning technology is a satellite-based radio navigation positioning technology with the following characteristics:

[0007] (1) Global all-weather positioning: There are a large number of GPS satellites and they are evenly distributed, which can ensure that at least four GPS satellites can be observed simultaneously at any place on the earth at any time, ensuring the realization of global all-weather continuous navigation and positioning services.

[0008] (2) High positioning accuracy: GPS relative positioning accuracy can reach 10m~6m within 50km, 10m~7m within 100km~500km, and 10m~9m within 1000km. In the precision positioning of 300m~1500m engineering, the plane position error is less than 1mm when observing for more than 1 hour. Compared with the side length measured by ME-5000 electromagnetic wave rangefinder, the maximum difference in side length is 0.5mm, and the error in correction is 0.3mm.

[0009] (3) Short observation time: With the continuous improvement of GPS systems and the continuous updating of software, relative static positioning within 20 km only takes 15 to 20 minutes. In the case of fast static relative positioning measurement, when each mobile station is within 15 km of the base station, the observation time of the mobile station is only 1 to 2 minutes. When adopting the real-time dynamic positioning mode, each station observation only takes a few seconds.

[0010] At present, most positioning trackers use Bluetooth tracking, but the Bluetooth transmission distance is only 10m to 100m, which is too short to effectively track and locate. At present, positioning trackers based on GSM communication transmission have the problem of high GSM transmission power consumption and inability to achieve point-to-point real-time control.
