Urban logistics system and method based on Scrapy frame and four-rotor aircraft

Abstract

The invention discloses an urban logistics system and method based on a Scrapy frame and a four-rotor aircraft. A hardware platform of the four-rotor aircraft comprises an inertial navigation unit, amulti-degree-of-freedom camera holder, a distance measuring module, a GPS positioning module and a communication module. A data acquisition module mainly comprises a sensor real-time acquisition module and a network information crawling module; an image recognition module is used for analyzing image data acquired by the camera holder, and for marking and positioning, alarming and early warning, carrying out OCR text recognition on an express note by calling a hundred-degree API, acquiring a geographical position, converting the geographical position into longitude and latitude information to obtain an order form destination position, and distributing an instruction signal to a flight control module; the flight control module is used for carrying out attitude calculation on the data acquired by an inertial navigation unit and enabling the aircraft to fly autonomously according to the instruction signal of a control base station; and the control base station and the aircraft adopt two-way communication. According to the invention, the efficiency of the unmanned aerial vehicle logistics system can be improved.

Description

technical field [0001] The invention belongs to the technical field of quadrotor aircraft, and more specifically relates to an urban logistics system based on a Scrapy framework and a quadrotor aircraft. Background technique [0002] Quadrotor UAV is a special aircraft that can fly completely autonomously according to a predetermined trajectory, and can control its attitude changes through wireless remote control commands. Compared with other UAVs, the quadrotor UAV has the characteristics of simple structure, convenient operation, easy control, low cost, stable flight, and strong mobility. Complete the designated flight mission in the space. [0003] Scrapy is currently the mainstream crawler framework. It is implemented based on the twisted asynchronous network library. Compared with other crawlers, it is efficient in terms of crawling speed and is customizable. It can not only crawl network data, but also can be used to obtain The data returned by the API. Using Scrapy...
