Abstract：In the frontier areas of future networked environments, related enterprises require the use of distributed sensors, such as drones, to complete special tasks. These tasks necessitate precise real-time control and high levels of collaborative operation, with stringent demands on security and anti-interference capabilities. This paper focuses on Time-Sensitive Networking (TSN) and proposes an integrated system for both wired and wireless TSN cross-domain fusion. It designs cross-domain converters and interfaces for wired and wireless TSN, preserving the time-sensitive characteristics of cross-domain information. The integrated network has been tested for end-to-end Scheduled Traffic (ST) latency across a three-hop network, demonstrating a delay of less than 4000 microseconds. The system achieves an integration of air-space Wireless Local Area Network (WLAN) and ground-based wired TSN for the transmission of time-sensitive traffic (ST), introducing deterministic communication mechanisms to ensure the real-time nature of data transmission under varying network conditions and enhancing the security of data transmission.
