The operation principle of each circuit is described in detail below.

(1) Ringing detection circuitry:

the ringing detection circuit is designed as shown in fig. 3, and the working principle is as follows: the telephone line is supplied with a dc voltage of about-48V by the telephone exchange before future ringing of the telephone line. When a telephone line is called, the telephone exchange sends out an ringing signal. The power supply voltage is +48V (forward potential) and 24V and 25HZ alternating current are overlapped, so that the power supply voltage becomes 72V alternating current 25HZ oscillating signal. This will ringing. When the circuit detects ringing signals, the circuit takes three ringing rings as the reference, namely, no person is off-hook after three ringing rings, and the singlechip controls the automatic simulation of off-hook. As shown, when the telephone line is not being driven, the telephone line provides a voltage of-48V, the optocoupler is not conducting, and pin 4 remains high. When the telephone is put in, the telephone line provides +72 AC voltage, the C1 capacitor is used for blocking, the R2 resistor is used for limiting current, the photoelectric coupler is conducted, and the photoelectric coupler pin 4 is changed into low level. The telephone rings are sent with a period of 5 seconds, i.e. 1 second, and 4 seconds are broken. So after the singlechip records 3 times of low level through the P3.4I/O port (the times can be controlled by the singlechip program), the singlechip controls the automatic off-hook.

(2) Automatic off-hook and on-hook circuit

According to the relevant standard, provision is made for: the off-hook DC resistance of any telephone should be less than or equal to 300 omega, and the off-hook DC resistance of an electronic telephone with an R key should be less than or equal to 350 omega. In the on-hook state, the leakage current is less than or equal to 5 mu A. When the user goes off-hook, the telephone is connected to a load of about 200Ω through the cradle, causing a current of about 30mA to flow through the entire telephone line loop. After detecting the current, the exchanger stops ringing current transmission, and changes the line voltage into direct current of more than ten volts, thus completing connection. Fig. 4 is a schematic diagram of an automatic on-hook and off-hook circuit. The principle is as follows: the singlechip receives 3 times of low level signals from the optocoupler pin 4 and returns a low level signal to the P2.2I/O port. When receiving the low level signal, the off-hook indicator lamp D1 is turned on, and PNP is turned on due to the characteristics of the PNP triode. The relay will be attracted from pin 5 to pin 6. The telephone line 1 then forms a loop through resistor R3, the transformer, the relay and telephone line 2, the resistor R3 and the transformer forming a resistor of about 300 Ω, whereupon the telephone goes off-hook.

(3) Decoding circuit

This embodiment is described using a DTMF decoding circuit as an example, and is implemented using MT8870 and peripheral circuits shown in fig. 5. Working principle: MT8870 is a DTMF signal reception processing dedicated chip, and its function is to decode the received DTMF signal into a 4-bit binary code, which is directly output by Q0-Q3. After automatic off-hook, the dual-audio signal enters the-IN pin of MT8870 via an audio-specific transformer. The double-audio signal is firstly filtered by a dial tone filter in the MT8870, then is sent to the double-audio filter by a pre-amplifier, the double-audio signal is separated according to high-frequency and low-frequency signals, is sent to a decoding circuit by the high-frequency and low-frequency filters and an amplitude detector, and finally outputs corresponding codes from a data output end of the MT 8870. To obtain valid data, stD of MT8870 receives INT1 of AT89C 52. When the StD level is from low to high, the effective dialing key value code is received through the IO interface after being detected by the AT89C 52. By testing, the number keys are pressed at the other end, and can be decoded.

(4) Data recording circuit

The data recording circuit is used for recording the operation password and preventing potential safety hazards caused by malicious control equipment. Before a person dials a telephone to control the starting of the tape machine, the operator needs to input an operation password, the password is only mastered in the hand of the driver of the tape machine, the DTMF circuit is in a working standby state at any time after the driver dials the telephone, the driver is prompted to input the password by voice, and at the moment, the driver presses a telephone key to input the password. As shown in fig. 6, the data recording circuit including the AT24C02 chip is shown, the DTMF decoding portion decodes the driver input digits and transmits the decoded digits to the single-chip microcomputer, the single-chip microcomputer receives the digits and then communicates with the AT24C02 chip through the P2.0 and P2.1 interfaces and the I2C 02 chip to read the preset password in the AT24C02 chip and compare the password with the code decoded by DTMF, if the password is consistent, the next operation can be performed, otherwise, the single-chip microcomputer increases the potential of the P2.2I/O port to be high (automatic on-hook), the EEPROM capable of being powered off and memorized is selected, and the A0, A1 and A2 on the 24C02 are address coding pins.

(5) Voice prompt module

For a telephone remote operation tape machine, under the condition of limited sight, voice prompt is particularly important, as shown in fig. 7, the scheme selects a JQ8900 type voice module which can perform I/O port operation and serial communication control, a built-in virtual U disk of the module can directly store audio files through a computer, a built-in small-power amplifier module of the module can directly drive a loudspeaker to omit a peripheral power amplifier circuit, and a singlechip is used for communicating through a P3.0 serial communication port and a P3.1 serial communication port and controlling a voice fragment played by the module during operation.

(6) Singlechip microcomputer

Fig. 8 shows a single-chip microcomputer circuit, the working principle of which is as follows: and P3.4 is connected with the fourth pin of the optocoupler, and when the singlechip receives the low level and accumulates for 3 times, the singlechip controls P2.2 to output a low level signal to the base electrode of the off-hook relay control triode. The relay is attracted and taken off the machine. P1.0-P1.3 are connected with QO-Q3 pin of MT8870 to receive 4-bit binary code. Then P3.0 and P3.1 are connected with the communication pin of JQ8900 so as to control the JQ8900 module to play corresponding voice prompt when in serial communication with 89C 52. P2.0 and P2.1 are connected with the AT24C 02I 2C communication pin to read and store the password. The clock pulse of the SPI interface is provided by P1.7 of 89C52 to the SCLK pin of ISD 4004. P2.0-P2.3 are connected with QO-Q3 pins of MT8870 to receive 4-bit binary codes. P2.3 and P2.4 are connected with control triodes of two output relays, and the relays can be attracted at low level.

(7) Machine head controller

Taking the controller shown in fig. 9 as an example, the user needs to press the button 4 on the keyboard (the normal belt can be started when the belt is protected), and press the button 8 to stop. A relay control key circuit as in fig. 9 is available according to the 4*4 matrix keyboard principle. The additional telephone centralized control loop in this scheme comprises the following components: (a) a BOX-128 type telephone call firewall module; (b) a tape dispenser telephony control module; (c) Telephone line several meters (from head phone to controller); (d) intrinsic safety junction box one. The installation method comprises the following steps: an intrinsic safety junction BOX is added at the incoming line of the machine head explosion-proof telephone set, a telephone line is connected in parallel and is led into a machine head controller, the incoming line is connected with a BOX-128 type telephone incoming call firewall incoming line placed in a controller BOX, and outgoing lines of the firewall are connected to a telephone line interface of a telephone dialing control module. The lines (normally open contacts are used as keys) of the 4# key and the 8# key are found out from the operation key board flat cable inside the machine head controller and are respectively connected to two output relays of the telephone control module, and when the relays are electrified, the 4# key or the 8# key of the controller is pressed, which is equivalent to manually starting or stopping the belt. And finally, a 5VDC power supply is taken from the inside of the controller to supply power to the telephone dialing control module, so that the installation of a control circuit is completed.

Referring to the telephone control tape machine logic shown in fig. 10, when in use, the telephone number of the tape head is dialed, after 3 sounds are sounded, the voice prompt inputs a password, after the password is input correctly, the belt is started by pressing the key 1, the belt is stopped by pressing the key 2, and after the operation is finished, the machine is hung by pressing the key #. The application of the scheme makes up the defects of the current control method of the tape machine, and the built-in password of the telephone control module ensures that misoperation does not occur to a certain extent. The scheme can obtain economic benefit, and is specifically as follows: the reduction of the belt patrolling workers arranged every production shift for 2 people/day, and the annual labor cost saving of 2 x 20 = 40 ten thousand; the belt is stopped or the net is broken, the influence is calculated for 6 times in the whole month, 20 minutes can be saved each time, the tunneling time can be gained in the whole month for 2 hours, the total footage is about 20 meters, the annual effectiveness is 20 meters/meter 600 yuan/meter 12 months = 25.2 ten thousand yuan; in conclusion, only one tunneling team can create 65.2 ten thousand yuan, and the overall mine is 521.6 ten thousand yuan for 8 tunneling teams, so that the benefit is more objective if a mine main transportation system is also put into use.
