Abstract

PURPOSE: A silver system and method using a telephone office line is provided to conveniently communicate with old people living alone by confirming the conditions of activities of the people using an existing central office line at all times, and by promptly dealing with the emergency. CONSTITUTION: A call signal received through a central office line is received from an arbitrary user(s1). A ring signal is detected from a reception sensing unit(s2). It is confirmed whether the time required for detecting the ring signal exceeds the set time(s3). In case that the time required doesn't exceed the time, a call is connected in a general call mode state(s4). In case that the time required exceeds the time, the call is connected in an automatic call mode(s9). In case that a loop circuit is composed of a trans unit(s10), a dial signal inputted from the line is received to a receiver unit(s11). The signal is converted into all sorts of BCD(Binary Code Decimal) codes(s12). The BCD codes converted are inputted to a control unit. The control unit generates control signals and operates an amplification unit(s13). The user talks to a silver system user on the telephone in a hands-free mode(s14). A sensing unit is installed outside of the silver system. A sensing signal is received from the sensing unit(s5). It is confirmed whether the sensing signal is received within determined time(s6). In case that the sensing signal isn't received, a telephone number stored in a special memory unit is converted into a BCD code(s7). The code converted is converted into a DTMF signal(s8).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a flow chart performed by the silver system according to the present invention. First, when a call signal transmitted through a telephone line is received from any universal telephone user (s1), the ring detection unit detects a ring signal (s2). Then, it is checked whether the time required for detecting the ring signal exceeds the prescribed time (s3). If the ring signal is detected without exceeding the prescribed time, the call is made in the normal call mode state (s4). However, if the specified time is exceeded, the automatic call circuit, that is, connected to the automatic call mode (s9). The automatic call mode is a hands-free mode, in which a call can be made immediately without picking up the handset. Then, when the loop circuit for making a call is configured by the transformer unit (s10), the dial signal input from the trunk line is received in the receiver unit (s11), and converted into various BCD codes (B12) (s12). . The converted BCD code is input to the control unit, and the control unit generates a control signal and operates an amplifying unit for amplifying the signal input to the transmitter and the signal output from the receiver (s13), and finally, the general telephone user and the silver system user. Makes a call in hands-free mode (s14). In addition, by selectively installing a detection unit such as an infrared sensor or a contact sensor outside the silver system to receive a detection signal from the detection unit (s5), check whether the detection signal is received within a specified time (s6), The phone number stored in the separate memory unit is converted into a BCD code (s7), the conversion code is converted into a DTMF signal, and dialed to the corresponding phone number (s8). Then through the step of connecting to the automatic call circuit (s9) in order to proceed to the next step. However, the time defined for detecting the ring signal may be arbitrarily set by the user in the silver system. For example, if you don't pick up the phone after 10 rings, you can set it up so that it can be connected to an automatic call circuit. When the specified time is set to 8 hours in receiving the detection signal, the time is checked by a timer mounted on the controller. If the detection signal is input within 8 hours, the timer is reset to check the time again from 0. If the detection signal is not input to the control unit for more than 8 hours, the automatic call circuit is connected. If the user can not hear the silver system user's voice in the hands-free mode during the process, it is possible to listen to the fine sound by driving the interception control circuit of the interception unit.

2 is a configuration example of a silver system according to the present invention, the relay unit 20 controls the opening and closing of the circuit, and the incoming detection unit 25 detects the ring signal from the call signal input through the relay unit. In addition, the talk time controller 30 checks the time required to detect the ring signal by the incoming detection unit 25 and drives the relay unit 20 if the ring signal is not detected until the predetermined time is exceeded. Enable automatic call circuit connection. In other words, when the phone rings, if it rings several times or more, it is connected to an automatic call circuit and is in hands-free mode. The prescribed time may be arbitrarily set and adjusted by the user. The transformer 35 is a means for modifying a voltage by an electromagnetic induction action, and constitutes a loop circuit for communicating in this system. The DTMF receiver unit 40 converts the dial signal input from the trunk line into a BCD code. Dual Tone Multi Frequency (DTMF) is a signal that is generated when the phone's dial button is pressed. The controller 45 receives the BCD code and generates various control signals. The amplifying unit 1 (50) receives a control signal from the control unit (On) and amplifies the received signal and outputs it to the receiving unit 55 including the speaker. The amplifier 2 65 amplifies the signal input from the talker 70 including the microphone. The interceptor 60 may select a person who has made a call or a user of a silver system by pressing a dial button, and allows the user to hear a minute sound.

3 is a configuration example of a silver system in which a separate sensing unit is installed outside according to the present invention, and the user may selectively configure the configuration example of FIG. That is, a separate sensing unit 75 such as an infrared sensor or a contact sensor is installed outside to receive a signal detected from the controller 45 at any time. The installation location is installed in the space where silver system users mainly live, or doors that pass through frequently. When the detection signal is not received by the controller 45 for a predetermined time, the memory unit 80 may automatically store a phone number for making a call in the hands-free mode. And converts the stored telephone number into a DTMF signal to configure a DTMF transceiver unit 85 for dialing. At this time, the user of the universal telephone and the user of the silver system may set the promised signal and press the emergency button in case of emergency to notify that it is an emergency. In the silver system configuration example as described above, when a user has a special reason such as when going out for a long time, the user can temporarily stop the operation by selecting a mode to go out.

As described above, the silver system and the method using the telephone line are more convenient with the elderly by using the existing telephone line and amplifying the handset in a situation where the population ratio is gradually aging and households composed of the elderly are living alone. It is possible to make a telephone call and install a separate sensing means at the entrances where the elderly are active, so as to periodically detect the activities of the elderly living alone, so that in case of an emergency in which the elderly can not move, the telephone number is immediately stored. This makes it possible to make an emergency call in hands-free mode.
