본 고안은 퍼스널 컴퓨터 내장형 팩스 모뎀기와 전화 착신 및 팩스나 모뎀에 의한 톤발생음에 의한 전원 제어장치를 결합한 것이다.The present invention combines a personal computer built-in fax modem with a power supply control device for incoming tones and tones generated by a fax or modem.

컴퓨터 보급이 확대되고, 그 활용의 일환으로 통신기기와의 결합의 용도가 늘어남에 따라 FAX 및 MODEM의 수요도 늘어나고 있다. 그러나 종래의 컴퓨터 결합형 MODEM, FAX로 사용하여 상기 통신을 하기 위해서는 퍼스널 컴퓨터의 전원을 향상 켜 두어야 하므로 불필요한 전력의 낭비와 기기의 열화를 초래하는 문제점을 가지고 있다. 이를 위하여 전화 착, 수신시만 동작하도록 주변 기기를 부착할 경우, 팩스 및 모뎀 통신과 일반 통신을 구분하지 못하는 경우, 통신전용회선이 아닌 이상, 전자 통신목적이 일반적인 전화에도 동작하는 문제점이 있다.The demand for FAX and MODEM is increasing as the spread of computers and the use of combinations with communication devices are increasing as part of its utilization. However, in order to perform the above-mentioned communication using a conventional computer-coupled MODEM and FAX, the power of the personal computer must be improved and turned on, which causes unnecessary power waste and device deterioration. To this end, when a peripheral device is attached to operate only when a call is received or received, when a fax and modem communication cannot be distinguished from general communication, there is a problem that an electronic communication purpose also works in a general telephone unless it is a dedicated communication line.

본 고안은 PC에 장착된 FAX 및 MODEN 등이 외부로 부터 호출이 있을때 FAX 및 MODEM이 발생하는 특유의 신호음이 검출될 경우에만 전원을 자동적으로 연결토록하므로써, 상기의 문제점을 해소시킬 수 있는 전원 자동 제어장치를 제공코자 하는 것이다.The present invention is designed to solve the above problems by automatically connecting the power supply only when a specific tone generated by FAX and MODEM is detected when FAX and MODEN, etc. mounted on the PC are called from the outside. To provide a control device.

상기와 같은 고안의 목적을 달성하기 위하여, (1) 외부와 연결되는 전화선에 유기되는 호출신호에 의해 발광되는 발광다이오드와 이와 같은 발광다이오드의 광에 의해 도통되는 포토 트랜지스터로 구성되는 포토 커플러의 출력신호로 전화를 수신상태로 전환하고, (2) 수신 후 수신음이 지정한 톤인지 검추하여, 지정한 톤일 경우에만 릴레이, 또는 전자 스위치로를 구동시켜 상기한 PC의 전원이 연결되도록 함으로서 무인시나 유인시를 막론하고 불필요한 응답을 없애면서, 외부의 신호를 수신할 수 있도록 하는 것이다.In order to achieve the object of the present invention, (1) the output of a photo coupler consisting of a light emitting diode that is emitted by a call signal induced by a telephone line connected to the outside and a photo transistor that is conducted by the light of such a light emitting diode (2) After receiving, check whether the incoming sound is the designated tone, and operate the relay or electronic switch only when the tone is designated, so that the power of the PC is connected. It is possible to receive external signals while eliminating unnecessary responses.

이하 본 고안을 첨부된 도면에 따라 상술한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도에서 (가)는 센서부로 포토커플러로 구성되며, (나)는 전화수신부, (다)톤 데코더(tone decoder), (라)는 타이머회로와 릴레이로 구성되거나 또는 릴레이 대신 전화회로에 의해 구성할 수도 있으며, (마)는 라인 콘트롤로 PC 등의 전원을 제어하는 것을 보인다. 이와 같은 각 기능에 있어서 포토커플러 대신 다른 검출회로를 사용할 수 있으며, 전원 회로부는 기계식이거나 전자식으로도 할 수도 있다.In Fig. 1, (a) is composed of a photocoupler as a sensor, (b) is a telephone receiver, (c) is a tone decoder, and (d) is composed of a timer circuit and a relay, or a telephone circuit instead of a relay. (E) shows that line control is used to control the power of a PC or the like. In each of these functions, other detection circuits may be used instead of photocouplers, and the power supply circuit unit may be mechanical or electronic.

본 고안의 이해를 위하여 기초적인 설명을 먼저하자면, 외부와 연결되는 전화 국선에는, 대기시엔 48볼트 정도의 직류 전압이 걸려 있으나, 직류루프가 형성되지 않아서 전류를 흐르지 않다가, 통화중에는 약 10V, 20㎃ 밀리 암페아 이상의 전류가 흐르도록 되어 있으며, 호출신호가 도래하는 경우는 16㎐의 교류성분의 전압이 75볼트 이상으로 걸리고 전화기 내부의 0.0uF 이 용량을 가진 콘덴서를 통하여 교류기 흐르도록 되어 있다.First of all, for the understanding of the present invention, a basic telephone line connected to the outside has a DC voltage of about 48 volts in standby, but a DC loop is not formed so that no current flows. A current of 20 mA or more is allowed to flow, and when a call signal arrives, the AC voltage of 16 mA is applied to more than 75 volts, and the AC flows through a capacitor with a capacity of 0.0 uF inside the telephone. .

따라서 전압 전위와 전류를 검출하는 회로를 사용하여 전화가 대기 상태인지 호출상태인지 또는 통화중인지를 판단할 수가 있음을 알아낸다.Thus, the circuit can be used to detect the voltage potential and current to determine whether the phone is on standby, in a call or on a call.

이를 감안하여 본 고안에서는 비교적 손쉽고 전화선로에 지장을 주지 않기 위하여 입력 전화선(L1, L2)의 한쪽(L1) 또는 (L2)에 포토커플러를 구성되고 있는 발광다이오드(PD1, PD2) 2개를 서로 반대방향으로 하여 전화 출력선(L'1, L'2)의 한쪽(L'1) 또는 (L'2)에 연결함으로서 임의의 방향으로 전류를 흐르게 다되 이로인한 전압강하는 약 1V로 통화에 지장을 주지 않도록 하며, 이와 결합된 포토트랜지스터(PQ1, 또는 PQ2)로 검출된 신호를 적당한 증폭회로 및 타이머회로를 거쳐 스위치(SW1)를 ON하는데 사용하도록 되어 있다.In view of this, in the present invention, two light emitting diodes PD1 and PD2 each having a photocoupler formed on one side L1 or L2 of the input telephone lines L1 and L2 are relatively easy and do not interfere with the telephone line. By connecting it to either L'1 or L'2 of telephone output lines L'1, L'2 in the opposite direction, current flows in any direction, and the voltage drop is about 1V. The signal detected by the phototransistor PQ1 or PQ2 coupled thereto is used to turn on the switch SW1 via an appropriate amplification circuit and timer circuit.

따라서, 스위치(SW1)가 ON되면 전화는 수신상태가 되어 각종 신호는 트랜스(T1)를 거쳐 톤데코더(Tome Decoder : 라)로 전달되며, 이와 같은 톤 데코더(Tome Decoder)는 FAX나 MODERM의 통신 프로토클에 의한 기초 신호 검출하여 출력되는 검출신호는 (라)의 타이머 회로(Time)의 리세트 입력으로 되어 전원을 작동시키도록 됨으로서 스위치(SW2) 또는 릴레이(Ry)의 릴레이 접점(a, b)를 ON 시켜 주게 되며, 통화가 끝나면 스위치(SW1)에 의해 지정된 시간 만큼 지연된 후 전원작동을 멈추도록 된 것이다.Therefore, when the switch (SW1) is turned on, the phone is in a receiving state, and various signals are transmitted to the tone decoder (Tome Decoder) through the transformer (T1), and such a tone decoder (Tome Decoder) communicates with FAX or MODERM. The detection signal outputted by detecting the basic signal by the protocol is the reset input of the timer circuit (Time) of (D) to operate the power supply so that the relay contacts (a, b) of the switch (SW2) or the relay (Ry) are operated. ) Will be turned ON, and after the call, the power will stop after the delay designated by the switch (SW1).

제3도는 PC의 전원스위치(SW1)와 본 고안 제어부의 릴레이 접점(a, b)을 병열로 설치함으로서 임의로 전원을 공급할 수 있도록 함을 도시하는 것이며, 제4도는 FAX나 MODEM과 결합하여 퍼스널컴퓨터 내에 장착하므로서 상승적 효과가 탁월한 비용절감으로도 이용할 수 있을 것을 보여 주는 것이다.FIG. 3 shows that the power switch SW1 of the PC and the relay contacts a and b of the control unit of the present invention can be provided in parallel so that power can be supplied arbitrarily. FIG. 4 is a personal computer in combination with FAX or MODEM. By mounting inside, it shows that the synergistic effect can be used with excellent cost savings.

상기한 바와 같이 본 고안에 의하면 유인시거나 무인시를 막론하고 통신용 전화신호에 의해서만 자동으로 퍼스널 컴퓨터의 전원을 제어할 수가 있어서 에너지의 소모를 최화할 수 있으면서도 FAX/MODEM과 결합함으로서 별다른 비용 상승없이 기능을 살릴 수 있으므로 산업적으로도 경쟁력이 높은 유용한 고안인 것이다.As described above, according to the present invention, the power supply of the personal computer can be automatically controlled only by the telephone signal for communication regardless of attraction or unattended, which minimizes the energy consumption, but combines with the FAX / MODEM without any additional cost increase. It is a useful design with high industrial competitiveness.
