The present invention relates to a method and apparatus for displaying an incoming call signal of a telephone. Particularly, an incoming call signal is primarily displayed using a light emitting diode (LED) in a place where a large amount of calls are used or a large number of telephones are held. The present invention relates to a method and apparatus for displaying an incoming signal of a telephone to be auditoryly displayed.

The conventional incoming call signal transmitting apparatus of the telephone includes a micro process 100 receiving an incoming signal from the switching center as shown in FIG. 1, and generating pulses according to a control signal output from the micro process 10. The unit 101, the switch SW1, the volume control unit 102 for adjusting the intensity of the sound in accordance with the switch of the switch SW1, and the amplified signal output from the volume control unit 102 to the speaker It consists of an amplification part 103 which sends out to SP.

The operation of the incoming signal transmitting apparatus of the conventional telephone configured as described above will be described in detail with reference to FIG. 2 of the accompanying drawings. The incoming signal transmitted from the switching center is input to the micro process 100 through the telephone line.

Accordingly, the micro process 100 drives the pulse generator 101 for outputting a control signal to notify the receiver.

In addition, the micro process 100 outputs a ringer signal, which is adjusted and output according to a switch SW operation by a user.

As shown in FIG. 2, the ringer signal is inverted through the resistor R1 and then phase-inverted through the inverter IN1, gain-controlled by the resistors R2 and R3, and then phase-inverted again by the inverter IN2. The output signal is also switched by the switch SW1 is phase-inverted to the inverter IN3 and then combined with the signal output from the inverter IN2 through the resistor R6 to adjust the pulse generated by the pulse generator 101. To adjust the volume.

The voltage thus adjusted is gain-controlled by the resistors R7 and R8 through the capacitor C1, amplified by the amplifier 103a in the amplifier 103, and then output, and then the speaker SP through the capacitor C4. ), The receiver knows that the call is coming.

However, the incoming signal transmission device of the conventional telephone has a problem that causes noise pollution as the telephone ring continues to ring in a place with a large amount of call or a large number of telephones, thereby causing a user to feel uncomfortable.

Therefore, an object of the present invention is to display the incoming signal primarily by driving the LED in the place where the number of calls or the number of telephones holding a large number of times, and the incoming signal of the telephone to prevent the noise by audible display using the bell secondly A display method and apparatus are provided.

An object of the present invention is to further include a display unit capable of visually displaying an incoming signal on an existing device, and a light emitting diode (LED) driver capable of driving a light emitting diode (LED) in the display unit and inputted from an exchange station. Judging the number of ringer signals, and if the ringer signal is one time, outputting a low-speed control signal to the output terminals P1 and P2 so as to emit light from the light emitting diode LED1; P1) outputting a high control signal to the low output terminal (P2) to light the light emitting diode (LED2); and if the ringer signal is three times, low control to the high output terminal (P2) to the output terminal (P1) Outputting a signal to cause the light emitting diode LED3 to emit light; and if the ringer signal is four or more times, a control signal is displayed on the pulse driver to audibly display the incoming signal.

3 is a block diagram of an incoming signal display device of the telephone of the present invention according to the micro process 1 receiving the incoming signal from the switching center and the control signals output from the output terminals P1 and P2 of the micro process 1. An LED driver 2 for outputting a light emitting diode (LED) driving voltage in the display unit 3, a pulse generator 4 for generating a pulse in accordance with a control signal output from the other terminal of the micro process 1, A volume control unit 5 for adjusting the sound intensity according to a switch SW2, a switch of the switch SW2, and an amplified signal output from the volume control unit 5 to be output to the speaker SP The amplification part 6 was comprised.

Referring to FIGS. 4 to 5, the incoming signal outputted from the switching center is applied to the microprocessor 1. do.

Unlike the related art, the micro process 1 first outputs a control signal to the ports P1 and P2 to drive the LED driver 2.

As a result, the LED driver 2 emits the light emitting diodes LED1-LED3 in the display unit 3 as shown in FIG.

At this time, the light emitting diodes (LED1-LED3) are sequentially emitted, the light emitting diode (LED) is controlled to emit light as shown in Table 1 below.

In Table 1, P1 and P2 are control signals outputted from the output terminal of the micro process 1, and H is a high signal, indicating that the light emitting diodes (LED) and Bell light and ring when the H signal is input.

Referring to Table 1, the LED driving is described in more detail. First, when the microprocessor 1 receives an incoming signal from the switching center, the microprocessor 1 receives a low (0) output port (P1) and a low (0) port (P2). ) Is output to the LED driver (2).

Accordingly, the LED driver 2 outputs a voltage for driving the light emitting diode LED1 first because the input signal is (0, 0), and this voltage passes through the resistor R9 to the light emitting diode LED1. As a result, the light emitting diode LED1 emits light to display a visual indication that an incoming signal has arrived.

After the predetermined time passes, the micro process 1 outputs a low (0) signal to the port P1 and a high (1) signal to the port P2 and applies it to the LED driver 2.

Accordingly, since the LED driver 2 receives the input signal (0, 1), the light emitting diode LED1 continues to emit light and outputs a voltage to emit the light emitting diode LED2. After vomit, the light emitting diode LED2 emits light by flowing to the light emitting diode LED2.

As described above, if the user does not pick up the handset even though the light emitting diodes LED1 and the light emitting diodes LED2 sequentially emit light, the microprocessor 1 waits a high time for the port P1 and a low level for the port P2 after a predetermined time. 0) The signal is output and applied to the LED drive (2).

Accordingly, the LED driver 2 outputs a voltage for emitting the light emitting diode LED3 while the LEDs 1 and 0 emit light while the input signals are (1, 0).

This voltage flows through the resistor R11 in the display unit 3 and then to the light emitting diode LED3, thereby emitting the light emitting diode LED3.

In this way, if the user does not pick up the handset even after visually displaying the LEDs (LED1-LED3) by sequentially emitting the light, the microprocessor (1) has a high (1) signal to the port (P1) and a high (1) signal to the port (P2). The output is applied to the LED driver (2).

Accordingly, the LED driver 2 knows that the time display is completed because the input signal is (1, 1), and outputs a voltage while driving the light emitting diodes (LED 1-LED 3) for auditory display. To apply.

The pulse generator 4 generates a pulse for ringing the bell by driving a pulse oscillator with a voltage input as in the prior art.

At this time, the ringer signal output from the other terminal of the micro process 1 is phase-inverted to the inverter IN1 after the resistor R1 and then gain-controlled by the resistors R2 and R3 and phase-inverted to the inverter IN2. It is output through the resistor R5.

In addition, by operating the switch SW2 by the user, the voltage Vcc is inverted to the inverter IN3 through the resistor R4 and is combined with the voltage through the resistor R5 through the resistor R4 to generate a pulse. The volume is controlled by adjusting the pulse output from (4).

The voltage adjusted in this way is gain-controlled by the resistors R7 and R8 after the capacitor C1 of the amplifier 6, is input to the amplifier 6a and amplified to a predetermined level, and then through the capacitor C4. By being transmitted to the speaker SP, the user is able to know that the telephone has been audibly.

As described in detail above, the present invention can sequentially emit light emitting diodes (LED1-LED3) to prevent noise caused by the telephone ring in a place where there are many calls or a large number of telephones in a visual expression. There is an effect that can be informed that the call came in a visual expression without the inconvenience caused by the telephone ring.
