Meanwhile, the transmitting / receiving unit 700 is connected to the signal input / output terminal of the main control unit 500 to receive the call processing signal and the emergency situation transmission message output from the main control unit 500, and then the corresponding party to the called party. While receiving the call processing signal from the called party and outputs to the main control unit 500.

Next, a control method of the PL terminal for overcoming an emergency according to an embodiment of the present invention having the above configuration will be described.

4 is an operation flowchart illustrating a control method of the PLC terminal for emergency situation overcoming according to an embodiment of the present invention.

First, the main controller 500 determines whether the emergency button 100 is turned on (S1).

In this case, when the emergency button 100 is turned on in the first step S1 (YES), the main control unit 500 transitions to an emergency call mode and simultaneously operates the state of the microphone and the earpiece unit 600. Transition to the stop state (S2).

In this case, the above-described second step S2 will be described in more detail with reference to FIG. 3.

The main control unit 500 outputs a microphone and earpiece blocking control signal to the microphone and the earpiece unit 600 when an emergency detection signal is input from the emergency button 100. Then, the fourth transistor 604 mounted in the microphone and earpiece part 600 is turned on by receiving the microphone and earpiece blocking control signal output from the main control part 500 so that the amplifier enable signal is turned on. Block the audio amplifier 602 from passing through. Therefore, even if the hook detection unit 300 detects the state of the handset as the off-hook state, the microphone and the earpiece unit 600 are in an operation stop state.

Thereafter, the main controller 500 determines whether the user inputs a phone number for the corresponding institution through the keypad 200 (S3).

In this case, in the third step S3, if the user does not input a phone number for the corresponding authority through the keypad 200 (NO), the main controller 500 determines whether the set waiting time has passed. Determine (S4).

If the waiting time set in the fourth step S4 has not passed (NO), the process proceeds to the third step S3 again, while if the set waiting time has passed (YES), the main controller 500 performs the memory 400. Lead any telephone number from among the telephone numbers for a number of applicable agencies stored in Thereafter, the main controller 500 attempts to call the corresponding authority through the transmitter / receiver 700 (S5).

Then, the main controller 500 determines whether the call connection is successful (S6).

In this case, if the call connection fails in the sixth step S6 (NO), the process proceeds to the fifth step S5 again. If the call connection succeeds (YES), the main controller 500 performs the memory 400. At the same time the message for emergency delivery stored in the) and outputs the message for emergency transmission to the transmitter / receiver 700 a number of times. Then, the transmitter / receiver 700 receives the emergency situation delivery message output from the main controller 500 and then transmits the number of times to the corresponding institution to which the call is connected (S7).

Subsequently, the main controller 500 continuously maintains the call connection state with the corresponding engine (S8).

In addition, the main controller 500 checks whether the emergency button 100 is pressed again (S9).

At this time, if the emergency button 100 is not pressed again in the ninth step S9 (NO), the main controller 500 proceeds to the eighth step S8, while the emergency button 100 is pressed. If it is pressed again (YES), the main control unit 500 transitions to the general telephone mode after releasing the call connection to the corresponding authority (S10).

On the other hand, if the emergency button 100 is not turned on in the first step S1 (NO), the main control unit 500 proceeds to the first step S1 while maintaining a normal telephone mode (S11). ).

On the other hand, when the user inputs a phone number for the corresponding organization through the keypad 200 in the third step (S3) (YES), the main control unit 500 is a phone number for the corresponding organization entered by the user It is determined whether and the telephone number for the corresponding organization stored in the memory 400 is the same (S12).

At this time, if the telephone number for the corresponding organization input by the user in the twelfth step (S12) and the telephone number for the corresponding organization stored in the memory 400 are not the same (NO), the main control unit 500 performs the first operation. If the telephone number for the corresponding institution input by the user and the telephone number for the corresponding institution stored in the memory 400 are the same (YES), the main controller 500 determines that the user After attempting to call the telephone number for the corresponding organization, the process proceeds to the sixth step (S6) (S13).

As described above, according to the WLL terminal for overcoming an emergency according to the present invention and a control method thereof, it is possible to more quickly overcome a non-communicable emergency that has occurred to a user, thereby preventing the mental and physical damage of the user due to an emergency. There is an excellent effect that can be minimized.
