Description

technical field [0001] The invention relates to 5G communication technology, RTK precise positioning technology and UAV item delivery, especially an application technology of UAV in hospital item delivery. Background technique [0002] At present, it is well known that the delivery of hospital items requires high accuracy, low damage rate, and low labor cost in the hospital. The disadvantages of logistics transmission are that the construction of cross-building transmission system is difficult, the cost is high, and the damage rate of transported items is high. The main disadvantage of rail logistics transmission is that the construction of cross-floor transmission tracks is difficult and the transmission efficiency is low. The construction costs of the above two methods are high, especially in the case of old buildings without reserved transmission channels, the construction needs to be rebuilt.

AI Technical Summary

Problems solved by technology

[0002] At present, it is well known that the delivery of hospital items requires high accuracy, low damage rate, and low labor cost in the hospital. The disadvantages of logistics transmission lie in the difficulty of building cross-building transmission systems, high cost, and high damage rate of transported items. The main disadvantages of rail logistics transmission are the difficulty of building cross-floor transmission tracks and low transmission efficiency.

The construction costs of the above two methods are high, especially in the case of old buildings without reserved transmission channels, the construction needs to be rebuilt

[0003] The current drones mainly use 4G communication technology and GPS positioning technology for flight control. This technology cannot meet the precise cruise and precise take-off and landing of drones in dense buildings and complex environments in hospitals, and cannot meet the requirements of hospital item delivery.

UAV automatic cruise relies on the UAV flight control system on the ground to transmit information such as UAV flight coordinates through the 4G network; due to the low bandwidth and high delay of 4G communication technology, there may be delays in command transmission or loss of instructions; Failure to transmit flight information and control signals with the UAV flight control system in time during the flight will cause the UAV flight to deviate from the route, and the UAV may collide in a densely built environment, resulting in a crash

Due to the low positioning accuracy and poor stereo positioning effect of GPS, there will be meter-level errors during the flight of the UAV.

To sum up, the existing UAV communication and positioning technology cannot meet the precise flight requirements required for item delivery in the complex environment of the hospital
