The dial tone generator 15 generates a dial tone for the telephone number to be contacted in an emergency under the control of the controller 16 and applies the generated dial tone to the call path switching unit 12.

The controller 16 controls the room monitoring operation in the telephone. When an alarm status signal is applied from the level detector 13, the controller 16 controls the generation of a dial tone for the telephone number previously stored in the memory 19. Controlling the operation of outputting the dial tone, the alarm message and the room monitoring signal to the telephone line through the call path configured by controlling the call path switching unit 12.

The voice signal generator 17 generates a voice signal for an alarm message under the control of the controller 16 and applies the generated voice signal to the call path switching unit 12.

The key input unit 18 is provided with a plurality of key buttons for setting the room monitoring function.

The memory unit 19 stores a room monitoring operation time, a telephone number to be contacted in an emergency, and an alarm message.

Room monitoring operation in the telephone according to the present invention configured as described above is performed in the order as shown in FIG.

First, the telephone user sets various functions for room monitoring and stores them in the corresponding telephone. The user operates the key input unit 18 to enter room monitoring operation time (start time and end time) and a plurality of telephone numbers to be contacted in an emergency. When input, the room monitoring operation time and a plurality of telephone numbers input by the control unit 16 is stored in the memory unit 19, and the alarm message input through the microphone (MIC) from the user corresponding memory unit 19 Store in

When the controller 16 recognizes the start of the room monitoring operation in a state where various functions for room monitoring are stored in the memory unit 19 of the corresponding telephone, that is, the user operates the key input unit 18 to operate the room. When a specific button for starting the monitoring operation is input or the corresponding room monitoring operation start time is reached (step S11), the control unit 16 turns on the microphone MIC to perform the room monitoring function (step S12). ).

Then, the microphone MIC operates to perform a room monitoring function. The microphone MIC converts various sounds generated from the surrounding into an analog electric signal and converts the converted analog electric signal, that is, the room monitoring signal into an amplifying unit ( 11), the room monitoring signal applied by the corresponding amplifier 11 is amplified and applied to the level detector 13. In response to this, the level detection unit 13 detects the level of the amplified room monitoring signal (step S13), and compares whether the detected signal level is equal to or greater than the predetermined level (step S14). The feedback operation is performed in step S13 to continuously detect the ambient sound.

However, if the signal level is greater than or equal to the predetermined level in step S14, the level detection unit 13 applies an alarm status signal to the control unit 16, whereby the control unit 16 stores the emergency state previously stored in the memory unit 19. The highest telephone number is extracted from the telephone number to be contacted (step S15).

Subsequently, the control unit 16 dials the withdrawn telephone number and notifies the called party of the alarm message. The controller 16 controls the dial tone generator 15 to generate a dial tone for the withdrawn telephone number, and generates the dial. The tone is output through the telephone line switching unit 12 to the telephone line to dial the telephone number (step S16). After step S16, the ring tone detection unit 14 detects the ring tone from the call path switching unit 12 and applies a ring tone detection signal to the control unit 16 in accordance with the detected result, wherein the control unit 16 via the telephone line It is checked whether or not the call tone is continuously input to the call path switching unit 12, that is, whether or not the call tone detection signal is continuously applied from the call tone detection unit 14 to answer the call (step S17).

In step S17, if the other party does not answer the call, that is, if the corresponding ring tone detection signal is continuously applied for more than a predetermined time counted by the controller 16 itself, the controller 16 sends the memory unit 19 to the memory unit 19. After retrieving the next telephone number to be stored in emergency (step S21), a return operation is performed in step S16 to repeat the operation until the call is made.

By the way, if the other party answers the call in step S17, that is, the corresponding ring tone detection signal ends, the control unit 16 withdraws the alarm message previously stored in the memory unit 19 (step S18). The signal generator 17 is controlled to generate a voice signal for the corresponding alarm message, and the generated voice signal is output to the telephone line through the call path switching unit 12 to notify the called party of the alarm message (step S19). ).

Thereafter, the control unit 16 controls the communication channel switching unit 12 to form a communication path between the amplifying unit 11 and the telephone line, and a room monitoring signal amplified and applied by the corresponding amplifying unit 11. By outputting to the telephone line through the call path configured in the corresponding call path switching unit 12, the called party can hear the sound generated in the house from the outside to recognize the internal situation (step S20).

As described above, the room monitoring function in the telephone according to the present invention continuously monitors the sound generated in the house when the corresponding function is set, and when an abnormal situation occurs, an abnormal situation occurs in the house by automatically calling a pre-stored phone number. Consumers who often leave their homes can go out with confidence by notifying the called party, and no one in the house where the phone is installed operates without being able to detect it. Security features that let you know what is happening in your homepage will be available.

As described above, in the present invention, when the room monitoring operation time, the telephone number to be contacted in case of emergency, and the alarm message are stored in advance, the phone number stored in advance is not recognized by the insider when an abnormal situation occurs in the house during the set room monitoring time. By making a call to a caller who can notify the called party immediately, the room monitoring function can be improved.
