This invention discloses a vehicle-mounted
Ethernet gateway device and its monitoring method based on a dual 5
G network, aiming to solve the problems of insufficient bandwidth, single interface, and unstable connection of existing vehicle-mounted gateways. The device adopts dual 5
G network modules (optional dual 5G or 5G+4G / Redcap configuration), integrating 6 vehicle-mounted
Ethernet interfaces (3 1000 / 100BASE-T1 and 3 100BASE-T1), 2 M12 standard
Ethernet interfaces (1000 / 100BASE-TX), 2 CAN interfaces (expandable to 3), 2
digital input (DI) interfaces, and 2 digital output (DO) interfaces. It supports V2X (vehicle-to-everything) and PTP (
Precision Time Protocol) protocols, enabling remote vehicle status monitoring and multi-link
backup. The device is based on a quad-core A55 CPU (maximum frequency 2GHz), 2GB RAM (expandable to 4GB), and 8GB eMMC
flash memory (expandable to 16GB), providing secure
data transmission through cellular networks, Wi-Fi (optional Wi-Fi6), and VLAN technology. This invention improves vehicle operating efficiency and is suitable for intelligent transportation systems.
