Development of an amplified telephone system for mine-used belt conveyor
In view of problem that voice alarm sound ca't broadcast along belt of existing monitoring system of mine-used belt conveyor, an amplified telephone system for mine-used belt conveyor was developed.The system has functions of voice alarm, half-duplex communication and dot calls and contact, and has good sound clarity with volume as high as 100 dB, which can satisfy requirements of complex environment of coal mine.
