Abstract
The utility model relates to a mine broadcasting system based on a telephone exchange. The mine broadcasting system comprises a single chip microcomputer used for controlling the operation of the broadcasting system. The single chip microcomputer is connected with an off-hook unit used for connecting a calling. The off-hook unit is connected with a bell detecting unit connected with the single chip microcomputer. The off-hook unit is connected with an audio transformer used for amplifying a telephone signal. The audio transformer is connected with multiple audio amplifying telephones. The single chip microcomputer is also connected with a telephone chip used for dialing. The telephone chip is connected with a dialing signal amplifying unit used for amplifying a dialing signal. The dialing signal amplifying unit is connected with the audio transformer. A detecting signal amplifying unit used for amplifying a feedback signal when a number is dialed is connected between the audio transformer and the telephone chip. The mine broadcasting system is achieved by reconstructing a conventional mine telephone line so as to save vast reconstruction cost and achieves mutual conversation between a position outside the mine and a position in the mine. In addition, the mine broadcasting system has a broadcasting function from the position outside the mine to the position in the mine.
