KJJ220 mining general and intrinsically safe data transmission interface

The mining general and intrinsically safe data transmission interface is part of the communication of the online monitoring system. The transmission interface realizes interactive communication between uphole and downhole, and completes the computer's collection of downhole data. As a connector between the uphole and underground, the transmission interface adopts photoelectric isolation to ensure the isolation of signal electrical relationships. It uses a shielded isolation power transformer to ensure the isolation of power electrical relationships. It adopts industrial field bus to ensure the stability and reliability of communication.
