Abstract
There are many kinds of monitoring and detecting load equipments in the Nearspace-air-vehicle-ground network, including visible light, infrared pods and various sensors, and there are various bus interfaces for communication and transmission of different types of loads, including network port, RS422, CAN, LVDS and so on. This paper proposes the use of FPGA and embedded Linux system software and hardware cooperation method to achieve interoperability between multi-bus interface and Ethernet, making full use of software flexibility and hardware fast forwarding capabilities. The test results show that this method realizes the data transmission between the multi-interface bus and Ethernet, and plays an important role in the transmission of information between the landing platform and ground in the Nearspace-air-vehicle-ground Dedicated Network
