Abstract

The invention provides a data link service processing system and method for networked encrypted transmission, which divides the transmitted information data into service data and network data, and forms fixed-length framing according to the framing transmission mode set by the service data. Data, the network data is formed into variable-length framing data according to the framing transmission mode set by the network data; the fixed-length framing data and variable-length framing data are encrypted by the data, and then transferred to the ring storage at a variable speed, and further through the equal-length framing data. The interface protocol frame is uniformly transmitted to the wireless link for data transmission; in the service processing system at the receiving end, the data transmitted by the wireless link in step S3 is decrypted, deframed, and forwarded by the reverse order protocol to complete the information data transmission. The data link service processing system and method for networked encrypted transmission according to the present invention realizes the networked service transmission function and meets the performance requirements of the system for multi-protocol adaptation, service dynamic expansion and real-time link transmission.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle system communication, and in particular relates to a data link service processing system and method for networked encrypted transmission. Background technique [0002] As a key component of the UAV system, the data link is mainly responsible for the two-way business communication between the UAV and the ground. In terms of business transmission, the data link may be connected to various business equipment including flight control, mission pods, payload services, networking terminals and other link end systems. It adopts a network interface communication mode that integrates service transmission, command control, state monitoring, collaborative sharing and heterogeneous communication. For different operation subjects, the UAV system needs to adjust the combination of business terminals in time, which introduces the problem of adapting the link system to multiple types of network co...
