Embodiment 1

[0045] Such as figure 1 As shown, the present embodiment provides a TDMA networking method for UAV communication, including the following steps:

[0046] S1. The base station sends broadcast signals to the UAV, so that the UAV and the base station can synchronize TDMA time slots.

[0047] TDMA time slots include: control time slots and business time slots.

[0048] S2. The base station receives the UAV time slot allocation request.

[0049] The base station receives the UAV time slot allocation request, including:

[0050] The base station receives the drone slot allocation request through the control slot.

[0051] S3. The base station generates TDMA time slots according to the number of time slot allocation requests received from the UAV, so that the UAV can perform data transmission on the corresponding TDMA time slot. Figure 2-4 is the TDMA time slot diagram when the number of UAVs is 0, 1, and N, and the UAVs perform data transmission on the corresponding TDMA time s...

Embodiment 2

[0077] The features of this embodiment that are the same as those of Embodiment 1 will not be described in detail. The features of this embodiment that are different from Embodiment 1 are:

[0078] A kind of unmanned aerial vehicle communication TDMA networking method of the present embodiment, concrete steps are:

[0079] (1) The base station broadcasts channel TDMA time slots, and the time slots are divided into control time slots and business time slots.

[0080] (2) After the UAV receives the broadcast from the base station, it performs TDMA time slot synchronization, and after the synchronization is successful, it sends a time slot allocation request to the base station control time slot.

[0081] (3) After the base station receives the UAV's time slot allocation request, it allocates a time slot for the airborne radio station and responds to the UAV.

[0082] (4) After the UAV obtains the allocated time slot, it transmits data in its own time slot.

[0083] (5) When mu...

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...
