AI Technical Summary
Existing coal mine communication systems use cable communication, which has poor communication quality. In particular, it is easily damaged by moisture in the harsh underground environment, affecting the stability and reliability of communication.
The system employs wireless communication and utilizes fiber optic network communication systems. Through signal transmitting terminals, signal processing devices, and signal receiving terminals, it performs signal conversion, transcoding, compensation, and decoding processes. These processes include converting signals into electrical and optical signals, transcoding signals into optical signal modulation, compensating signals to restore their quality, and decoding signals into optical signal amplification or retransmission.
This avoids the problem of cable moisture, improves the stability and reliability of communication, enhances the stability, timeliness and reliability of data transmission, and solves the problem of low quality cable communication.
