<Example 1>

A broadcasting equipment remote start circuit by a telephone line, comprising: a circuit structure divided into a receiving circuit unit and a transmitting circuit unit;

(1) Receiving unit consists of voice message generating part consisting of ICs from U13 to U16, EEPROM U20 part storing password, U23 detecting ring signal of telephone line, U30 and U32 detecting whether call is disconnected and broadcasting equipment U39 detects whether the user is using U27, U27 detects dial numbers such as passwords, U33 U34 generates 20 필요한 ring signal when the subscriber automatically answers the subscriber, and ringback tone to be heard by DLEO subscriber ( It consists of U35-U38 which generates ring back tone), U31 which amplifies the voice signal to be broadcasted by the calling subscriber to the appropriate size and U17 which is a microcomputer that controls the whole, and U40 which supplies 5V power to the whole. Becoming;

(2) The voice message generating part is divided into 1/2 by U13 and U14 by the clock which is oscillated from U15 to 16 가 to apply ADDBUS to U16 which is 2MBIT EPROM and is selected by A14 to A17 applied by Micom. Outputting voice message data;

(3) The output data is D / A by the resistors R30 to 45, and the quantization noise is removed from the filter of U26, and then amplified and output by U25.

According to the circuit operation of the present invention, the ring signal of 20 걸려 from the telephone station is applied to U23 after full-wave rectification at Bridge 1 through C20, and the third terminal of U23 becomes H and is applied to the RC4 terminal of the microcomputer. When the microcomputer receives this signal, it operates the RY2 relay through the U19 to H of the RB0 terminal, answers the phone, checks the RB6 terminal through the U18, checks whether the SW13 is operating, and then checks whether the SW13 is operated. If you want to make a call with RY3 and RY4, the 20㎐ signal generated by U33 and U34 is amplified by Q6 and Q7 to send a signal to the subscriber's phone through T5 and ring by U35-U38. Send a RING BACK TONE to the calling party and find out if the subscriber answered by pin 3 of U23. If the subscriber responds, RT3, RY4 will recover and the subscriber's phone will be connected to the line so that the call can be made.

If you want to broadcast without calling or SW13 DL is off, if you enter your password after broadcasting your password, MFC TONE will be converted into BCD signal from U27's tone decoder and input into your microcomputer and your microcomputer will be recorded in U20. If it matches with the password, check pin 3 of U39 and if it is H, 220V voltage is applied to the AC 220V AUX terminal, so that the broadcasting equipment is in use and adjust the ADD of the terminal to RA0-3 to indicate that the broadcasting equipment is in use. If the terminal sends a message and this terminal is L, it operates the RY5 relay to supply power to the broadcasting equipment and to broadcast the message after the chime is sent. Note that the call from the transmitter sends a special tone. In case of receiving a tone, R3 relay operates immediately without a password.

When you hang up after the broadcast, your phone line will have a busy tone, which will be amplified by U32 and detected by U30 to make the RB5 terminal of the microcomputer L through U18. By operating the RY3 relay, regardless of the telephone line, connect the phone connected to the TEL LINE OUT to the tone decoder through the T3 transformer and record it on the U20 by changing the password input or password using the previous phone.

<Example 2>

In addition to the receiver configured as described above, in the circuit configuration of the transmitter of the eight-circuit case used when broadcasting the same contents to several places at the same time,

(1) Record U1 and U1 to record the broadcasting device, the telephone number of the receiver to be broadcast, U6 to dial the phone number, U6 to dial the phone number and U7 to change the MFC tone to BCD when the phone number is entered. Comprising a microcomputer U4 to control the entire signal detector circuit consisting of U10 and U11 to detect whether the line;

(2) It is composed of U12 to supply power.

As the action of the present invention on the operation of the transmitter as described above,

A. Phone number input process

If SW9 switch is pressed and the switch of SW1 to 8 is pressed, it will be the RA3 terminal H of the microcomputer and the position of the pressed switch among the switches of SW1-8 will correspond to the RCO-7 through U3. The terminal becomes H. The microcomputer is ready to receive and the telephone connected to TEL LINE OUT is connected to U7, the tone decoder through T1 transformer, so the tone decoder changes the MFC tone to BCD to Ucom's RC0-4 through U9. It is applied to the terminal and the microcomputer records this phone number along with the switch position in U5, the EEPROM. Repeat the process again, enter the previous 8 phone numbers, and restore the SW9.

B. Recording process of broadcasting contents

If you press SW11 with the microphone plugged in to J1, H is applied to RC6 of Microcomputer through U9. Microcom sends L to RA0 terminal to make U1 recording state using R / P terminal of U1 to RA2 terminal. Start recording with L. When recording is over and SW11 is restored, Micom restores U1 and waits for playback.

C. Broadcasting Course

If you want to broadcast all the phone numbers, SW10 switch will be selected.If you select some of them, select all the switches from SW1 to 8 and press SWITCH. Input to PCO-7 via U3.

In this state, if SW12 switch is pressed additionally, LED of all positions selected for broadcasting is turned on through U2, and then microcomputer sends H to RC5 to operate R1 relay through U8 to make a dial, and then dials dial numbers from RC0-5. Send MFC tone to U6, dial it, and divide the busy tone or ringback tone into its length by U9 and U11 through the U9. In case of busy tone, it is decided to broadcast later. If it is pending, dial the next number, and if ringback tone, ring back tone stops, send special number which is not used in general telephone through U6. After broadcasting the recorded contents without exchange, the corresponding LED turns off. In the same process, the next number is dialed and broadcasted to the place where the call is held.

As such, the broadcasting equipment remote start circuit by the telephone line according to the present invention is a circuit apparatus for starting and broadcasting broadcasting equipment from a remote place by using a general telephone or a mobile phone, and is separated into a transmitting circuit apparatus and a receiving circuit apparatus and installs only a receiving apparatus. In this case, it can be used as a general telephone.In this case, the password can be set so that no one can use the broadcasting equipment, so that the broadcasting equipment can be used only when the password is matched. In the case of manual use, it informs the user that it is in use so that there is no inconvenience to each other.In the case of a broadcasting circuit facility equipped with a simple broadcasting system, it can be broadcast to each room where a receiver is installed only in an exchange room equipped with a transmitter or a telephone exchange device or a broadcasting room.
