Therefore, an embodiment of the present invention will be described in detail with reference to the first, second, third, fourth, fifth, sixth, and seventh degrees.

First, an emergency call signal generation step will be described in detail with reference to FIGS. 2 and 3 and 4, and the second control unit 210 of FIG. 2 uses the switch detection unit 212 from FIGS. If a call key, such as the SWS signal, shown in FIG. 3 is input, it is monitored. If a call key corresponding to the SWS signal is detected, the process proceeds to step 312. The second controller 210 determines whether the manual selection switch 214 is selected as the DTMF mode or the dial pulse mode in step 312. When the manual selection switch 214 is selected as the DTMF mode, the second controller 210 controls the relay controller 216 to form a DTMF signal transmission loop in step 314. The relay controller 216 transmits the RCS signal shown in FIG. 4B under the control of the second controller 210 to transfer the relay 224 to form a DTMF loop. In addition, when the DTMF loop is formed, the second controller 210 outputs the CS signal shown in FIG. 4B to the DTMF transmitter 218 in step 316. When the CS signal is input from the second controller 210, the DTMF transmitter 218 transmits the DTMF signal shown in FIG. 4B corresponding to the emergency call signal according to the data including the CS signal.

However, if the manual selection switch 214 is selected as the dial pulse mode in step 312, the second controller 210 controls the relay controller 216 to form a direct current (DC) loop in step 318. . The relay controller 216 controls the relay 224 under the control of the second controller 210 to form a dial pulse loop, that is, a direct current (DC) loop. Formation of the DC loop means that a loop of CD bolts provided from the exchanger is formed, as when hooked off in a general telephone. In addition, the second controller 210 transmits the preset digital signal DS between 11-16 to the relay controller 216 in step 320. Accordingly, the relay controller 216 transfers the relay 224 by providing the RCS signal shown in FIG. 4A to the relay 224. When the RCS signal provided to the relay 224 is at a high level, the relay 224 is turned on to form the loop, thereby outputting a direct current of 48 volts (V). In addition, when the RCS signal provided to the relay 224 is at a low level, the relay 224 is turned off to cut the DC loop, thereby outputting 0 volts (V), so that the emergency call signal shown in FIG. The dial pulse corresponding to the DP is transmitted.

When the transmission of the DTMF signal or the dial pulse corresponding to the emergency call signal is terminated, the second controller 210 controls the relay controller 216 to block the transmission path of the emergency call signal in step 322. The relay control unit 216 is controlled by the second control unit 210 to switch the relay 224 to block the transmission path of the emergency call signal, so as not to disturb the telephone call of the subscriber. In addition, referring to FIG. 1 and FIG. 4 and FIG. 5, the process of transmitting an emergency call message to the key-phone terminal when the emergency call signal is input will be described in detail. In FIG. 5, the first controller 124 of FIG. It detects whether a DTMF signal or dial pulse corresponding to the emergency call signal is input from the calling device 110. If the caller 110 is set to the DTMF mode, the DTMF receiver 132 detects the DTMF signal input from the caller 110 and provides the DTMF signal to the first controller 124. However, when the calling device is set to the dial pulse mode, the dial pulse input from the calling device 110 is counted by the general subscriber interface unit 114 and provided to the first control unit 124. When the emergency call signal is detected in step 510, the first controller 124 records the extension number to which the call key is input in step 512, and analyzes the emergency call signal to find a corresponding message set in the ROM 126. In operation 514, the first controller 124 transmits the message set in the ROM 126 together with the ring signal generated from the ring signal generator 120 and the recorded extension number. When the transmission of the emergency call message including the extension number and the message is finished, the first control unit 124 detects whether the hook switch 618 of the key phone terminal 130 is hooked off in step 516, and if the hook off is detected. In step 518, transmission of the ring signal is terminated.

In addition, referring to FIG. 6 and FIG. 7 and FIG. 8, the process of calling an emergency call message is described in detail. Referring to FIG. 6, the third controller 616 of FIG. 6 includes a ring signal from the exchange in step 710 of FIG. 7. Monitor for emergency call messages, including extension numbers and messages. When the ring signal is detected by the ring detector 612 and the emergency call message is input in step 710, the third controller 616 controls the ringer sound generator 614 to transmit an ringing sound indicating an emergency call in step 712. The OPE 620 is controlled to display an emergency call message in the format shown in FIG. 8 on the LCD of the OPE 620. Thereafter, the third control unit 616 detects whether the hook switch 618 is hooked off in step 714, and stops ringing by controlling the ring tone generator 614 when the hook is off. Reset the LCD. The ringing tone and the displayed message are held until the hook switch 618 is hooked off.

Therefore, when the present invention is described with an embodiment, the extension number of the general subscriber telephone 112 is 140, the calling device 110 installed in the bathroom and the bedroom is set to the dial pulse mode and the corresponding digits 13, 14 Set to. In addition, in the ROM 126 of the exchanger, a BATH ALARM was recorded corresponding to 13 and BEDROOM ALARM was recorded corresponding to 14. In such an environment, when a user presses a call key due to an emergency in a bathroom, the second control unit 210 of the call device 110 detects this and transmits a dial pulse corresponding to the set 13. When the dial pulse corresponding to 13 is inputted, the exchanger stores number 140, which is the input extension number, and outputs the message BATH ALARM, which corresponds to 13, from the ROM 126 along with the ring signal and the extension number. . The phone terminal 130 receives the ring signal and transmits a ringing tone, and displays the extension number 140 and the message BATH ALARM in the form shown in FIG. 8 to indicate that an emergency occurred in the bathroom in room 140. .

As described above, in the present invention, a call device for generating an emergency call signal when an emergency occurs is matched with a general telephone line of a key phone system without providing a dedicated line. In addition, the emergency call signal sent out according to the installation location of the calling device can be identified quickly where the emergency situation occurs. And by storing the message according to the emergency call signal of each call device in the memory of the key phone system to accurately display the location of the emergency situation on the terminal during the emergency call has the advantage that it can perform the emergency call function more efficiently.
