■Overview

KJJ18 mine-used intrinsically safe gigabit ring network switch is a comprehensive universal network equipment that provides industrial ring network standard, broadband, high-speed information transmission and information integration access for various monitoring and control systems of coal mines. It is widely used in mine industrial video surveillance, personnel positioning, industrial control automation and other systems.
This product has reasonable system configuration, flexible networking, one network for multiple purposes, safety and stability, practicality and efficiency, strong anti-interference ability, automatic realization of ring network redundancy, fast connection establishment and failure connection recovery.

■Working principle
The switch establishes the mapping between the address and the switch port according to the source MAC address in the received data frame, and writes it into the MAC address table. The switch compares the destination MAC address in the data frame with the established MAC address table. Decide which port to forward, if the destination MAC address in the data frame is not in the MAC address table, then forward to all ports.
