UAV communication TDMA networking method, system, device and storage medium

Abstract

The invention relates to a UAV communication TDMA networking method, system, device and storage medium. The UAV communication TDMA networking method includes that a base station sends broadcast signals to a UAV so as to enable TDMA time slot synchronization of a UAV and the base station; the base station receives UAV time slot distribution requests; the base station generates TDMA time slots according to the quantity of the received UAV time slot distribution requests so as to enable the UAV to perform data transmission on the corresponding TDMA time slots. Dynamic generation and distributionof the quantity of the TDMA time slots of the base station are realized and the quantity of the TDMA time slots is decided according to the number of UAVs. Therefore, defects of channel waste when thequantity of UAVs is small and time slot distribution incapability when UAV data is excessive due to fixed time slot quantity in a prior TDMA communication method are made up. According to the invention, the UAV performs data transmission on the TDMA time slots, so that transmission efficiency and reliability are improved effectively, interaction time requesting is not required and transmission time delay is reduced.

Description

technical field [0001] The invention belongs to wireless networking communication, and in particular relates to a TDMA networking method, system, equipment and storage medium for unmanned aerial vehicle communication. Background technique [0002] At present, one-stop multi-device communication technology, UAV and base station communication is divided into two ways: [0003] 1: The drone sends a request to the base station, and then sends the drone data after passing; [0004] 2: The base station sends queries to the UAV in a fixed order to obtain UAV data. [0005] The UAV actively requests data transmission from the base station, which requires an interactive process, which will waste channel resources; [0006] In the existing TDMA communication method, the number of TDMA time slots is fixed. When there are few UAVs, the channels are wasted, and when there are too many UAV data, the time slots cannot be allocated; [0007] When UAVs are networked, when multiple UAVs se...

Problems solved by technology

[0005] The UAV actively requests data transmission from the base station, which requires an interactive process, which will waste channel resources;

[0006] In the existing TDMA communication method, the number of TDMA time slots is fixed. When there are few UAVs, channels are wasted, and when there are too many UAV data, time slots cannot be allocated;

[0007] When UAVs are networked, when multiple UAVs send requests to the base station at the same time, wireless signal collisions are prone to occur, resulting in data loss, and signal interference will cause data transmission failure;

[0008] The base station queries the UAVs in a fixed order and needs to know the number and ID of the UAVs connected to the base station in advance, which greatly reduces flexibility and cannot realize dynamic networking
