AI Technical Summary

Technical Problem

The transmission latency of drone communication equipment is increasing, and its user-friendliness and versatility are decreasing, especially due to the lack of uniformity in data processing between wired and wireless ports, which leads to a decrease in the universality of the data link.

Method used

The UAV data pass-through device based on the LWIP protocol stack processes data packets at the network layer of the protocol stack through the controller, and realizes the pass-through of data packets through the radio frequency interface unit and transceiver components. User data can be received or forwarded at the network layer by detecting the destination address, avoiding transmission to the application layer for judgment.

Benefits of technology

It reduces data transmission latency, improves the transmission efficiency and user-friendliness of transparent transmission devices, and enhances the versatility of the devices.
