Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0020] like figure 1 As shown, the present embodiment is a communication satellite-based universal access system for UAV data links, residing in the communication satellite control and management center, including a multi-threaded multi-tasking processing module, a network distribution module, and an IPC data exchange module.

[0021] (1) Network distribution module:

[0022] After the UAV, ground station and combat unit obtain the resources of the communication satellite, configure the port and IP address for each data sender and data receiver offline.

[0023] As the data core processing module, the ground station needs to realize the interconnection and intercommunication capability between the UAV, the ground station and the combat unit, and is used for commanding and controlling and distributing the information collected by the UAV. The...

Abstract

The invention discloses an unmanned aerial vehicle (UAV) data link universal access system based on communication satellites, which is applied in a communication satellite control and management center. The system comprises a multithread multitask processing module, a network distribution module, and an IPC data exchange module, wherein the network distribution module is used for configuring ports and IP addresses for data senders and data receivers in an offline manner; the multithread multitask processing module is used for creating a master control process after data is received from the data senders, the master control process comprises a plurality of threads, the received data is split through the threads, and the split data is repacked into data frame formats required by the data receivers; and the IPC data exchange module is used for scheduling the threads during processes. The system provided by the invention has the advantages that UAV ground stations needn't respectively construct relevant protocol conversion modules, so that the link access efficiency and the UAV interoperability are improved, and communication satellite communication transmission protocol requirements are satisfied.

Description

technical field [0001] The invention belongs to the integrated control technology of the unmanned aerial vehicle system, and solves the generalized access problem of the communication satellite communication data link in the unmanned aerial vehicle ground control station. Since the satellite communication data link uses a fixed ground data terminal, this technology innovatively connects to the universal interface conversion unit, integrates different UAV measurement and control protocols, and meets the general access requirements of different types of UAVs. [0002] technical background [0003] The UAV data link is the only link connecting the UAV and the ground command and control station system, which determines the effectiveness of the UAV system in performing tasks, and is the most important embodiment of the "unmanned" value of the entire system. In the actual use of the communication satellite communication link, in order to access the communication satellite communica...
