The Research of Ultra-Low Delay Gateway for Under-ground Remote Control

Abstract

The existing systems for coal mine safety oversight, worker location tracking, and video surveillance face issues such as intricate network topologies, limited capacity for additional device connectivity, and significant latency. Aiming at the complex underground multi-source heterogeneous network, this paper compares and analyzes the defects and shortcomings of the current network, designs the time-sharing protocol mapping model based on MII (Media Independent Interface), SPI (Serial Peripheral Interface), DMA (Direct Memory Access) and other high-speed data exchange bus, and proposes a fusion gateway suitable for underground ultra-low delay. The actual operation results show that the gateway has the characteristics of rich interface, less packet loss and low delay, which can meet the real-time communication requirements of underground CAN (Controller Area Network) bus, IoT (Internet of Things) and Ethernet equipment.
