[0002] At present, the explosion-proof speaker or its control device for mining can only automatically turn on the speaker expansion during a call, and automatically turn off the simple function of the speaker expansion after hanging up. To turn off the speaker, it is impossible to realize the function of automatically turning on the speaker for expansion after ringing a few times when no one answers.

Embodiment Construction
[0024] As shown in the figure, the 19th pin of the control chip IC1 in the operation indication and reset circuit of the intelligent control detection circuit is connected to the current limiting resistor R23, and the resistor R23 is connected to the negative pole of the light-emitting diode L1, and the positive pole of the diode L1 is connected to the DC power supply VCC (+5V); the first pin of the control chip IC1 is grounded to GND through the resistor R18, and the first pin of the control chip IC1 is connected to the DC power supply VCC (+5V) through the capacitor C8; the control chip IC1 can use the microcontroller AT89C2051.
[0025] The operation indication of the intelligent control detection circuit and the function of the reset circuit can observe the power supply indication and operation status of the device through the flickering of the diode, and can control the chip IC1 to re-run the program inside the chip after power-on to ensure the correctness of the program op...

The invention discloses an intelligent controlling detection circuit which comprises an intelligent detection circuit, an intelligent off-hook call controlling circuit, an intelligent call end busy tone detection controlling hanging-up circuit, an intelligent double audio frequency detection controlling circuit and an intelligent audio frequency amplifying and long-distance transmission controlling circuit. The intelligent controlling detection circuit can automatically turn on a sound box to carry out expanding broadcasting when no one answers a call, can independently select to turn on or turn off the sound box expanding broadcasting during a calling process, and turns off or turns on the sound box after the number of times of detection of busy tone is set after the phone is hung up.
Description
technical field [0001] The invention relates to a control circuit for detecting ring current signal tone, explosion-proof sound box and MP3 music switch, specifically an intelligent control detection circuit. Background technique [0002] At present, the mining explosion-proof speaker or its control device can only automatically turn on the speaker expansion during the call, and automatically turn off the simple function of the speaker expansion after hanging up. You cannot choose to turn off or turn on the speaker during the call, and the busy signal cannot be detected after hanging up. Turning off the speaker cannot realize functions such as automatically turning on the speaker for expansion after no one answers after ringing a few times. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent control detection circuit, which can automatically turn on the speaker for expansion when no one is answering th...
