Airport carrier positioning system based on LoRa and NB-IoT

Abstract

The invention provides an airport carrier positioning system based on LoRa and NB-IoT. The airport carrier positioning system comprises a carrier terminal, an indoor LoRa beacon, an NB-IoT base station, a hardware management platform, an application management platform and a user terminal. The main control MCU module of the carrier terminal is connected with an outdoor Beidou positioning module, an indoor LoRa receiving module, a vibration sensor module and an NB-IoT communication module, receives the external position information, the indoor position information and the state information, andexchanges information data with the NB-IoT communication module; the NB-IoT communication module packages the information data and reports the information data to the NB-IoT base station; and the NB-IoT communication module transmits the information data to a hardware management platform in a transparent manner, repackages the information data, outputs the repackaged information data to an application management platform and transmits information to a user through a user terminal, and the NB-IoT communication module preferentially packages and reports the outdoor position information data andthe state information data to the NB-IoT base station. According to the invention, the position of the carrier terminal is accurately positioned through double positioning modes of outdoor Beidou positioning and indoor LoRa beacon. And the use states of all carriers in an external field are known in real time, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an airport vehicle positioning system based on LoRa and NB-IoT, belonging to the technical field of transmission positioning. Background technique [0002] In the airport, various functional vehicles shuttle non-stop to transport people and goods to different places. All kinds of powered and unpowered vehicles, aircraft and ground crews work in the airport every day, shuttling between the apron and warehouses, maintenance warehouses, terminal buildings and other places. The airport has a large space, and staff or goods must use various vehicles to move from one place to another. This requires positioning the location of the vehicle that the user needs. At present, the way to find the vehicle is still in the basic visual The search stage often takes a lot of energy and time. [0003] The existing methods for finding vehicles have the following problems: low efficiency. At present, manual confirmation is required to find vehicl...

AI Technical Summary

Problems solved by technology

[0003] The existing methods for finding vehicles have the following problems: low efficiency. At present, manual confirmation is required to find vehicles outside the airport. Manually confirming vehicle positions and vehicle vacancy in such a large-area venue is not only inefficient, but also reduces vehicle utilization. The efficiency is low, and ineffective labor will also bring negative emotions, resulting in a vicious circle; Poor security: Outfield freight personnel frequently shuttle through the airport when looking for idle vehicles, which has certain potential safety hazards

Vehicles parked randomly (not parked in the specified area) also have certain potential safety hazards
