본 고안은 전화기의 파워리세트 회로에 관한 것으로, 특히 단말기의 파워를 오프시킨 후 다시 온시킴으로써 완전하 리세트를 행하여 단말기의 래치업(Latch up) 상태를 제거하고자 한 파워리세트 회로에 관한 것이다.The present invention relates to a power reset circuit of a telephone, and more particularly, to a power reset circuit for removing a latch-up state of a terminal by performing a complete reset by turning the terminal off and then on again. .
종래 리세트회로의 구성은 첨부한 도면 제1도에 도시된 바와 같이 파워 공급 및 데이타를 출력시키는 주장치부(101)와, 상기 주장치부(101)와 데이타를 교환하는 다수개의 단말기(102)로 구성된다.The conventional reset circuit includes a main unit 101 for supplying power and outputting data, and a plurality of terminals 102 for exchanging data with the main unit 101, as shown in FIG. It is composed.
이와 같이 구성된 종래 리세트회로의 동작을 상세히 설명하면 주장치부(101)는 터미널 케이블(Terminal cable)을 통하여 전원을 단말기(102)에 공급하게 되고 아울러 데이타도 상기 터미널 케이블을 통해 단말기(102)에 전송하게 된다.The operation of the conventional reset circuit configured as described above will be described in detail. The main unit 101 supplies power to the terminal 102 through a terminal cable, and data to the terminal 102 through the terminal cable. Will be sent.
이때 데이타 전송에 문제점이 발생하게 되면 주장치부(101)에서 리세트 신호를 출력하여 단말기(102)를 리세트시키게 된다.At this time, if a problem occurs in data transmission, the main unit 101 outputs a reset signal to reset the terminal 102.
그러나 이와같은 종래 전화기의 리세트회로는 단말기에 파워가 인가되어 있는 상태에서 리세트를 행하기 때문에 단말기가 래치 업 상태에 있는 경우 완전하게 리세트 되지 않는 문제점이 있었다.However, such a reset circuit of the conventional telephone has a problem that the terminal is not completely reset when the terminal is in the latched up state because the reset circuit is performed while the terminal is powered.
따라서 본 고안의 목적은 단말기의 파워를 오프시킨 후 다시 온시켜 완전한 리세트를 행함으로써 단말기의 래치업 상태를 제거하여 동작의 신뢰도를 향상시킬 수 있는 파워리세트 회로를 제공함에 있다.Accordingly, an object of the present invention is to provide a power reset circuit that can improve the reliability of the operation by removing the latch-up state of the terminal by performing a complete reset by turning off the power of the terminal again.
이하 본 고안을 첨부한 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 의한 파워리세트 회로도로서, 전원공급 및 데이타를 하이브리드 트랜스(2)에 출력하는 주장치부(1)와, 상기 주장치부(1)의 출력신호를 분리하여 단말기(3)에 출력하는 하이브리드 트랜스(2)와, 상기 하이브리드 트랜스(2)의 출력신호에 의해 구동되어 상기 주장치부(1)와 데이타를 교환하는 단말기(3)와, 마이콤(MICOM)의 제어신호에 의해 스위칭되어 상기 하이브리드 트랜스(2)에 전원(VF)공급을 온, 오프시키는 스위칭부(4)로 구성된다.2 is a power reset circuit diagram according to the present invention, which separates the main unit 1 for outputting power supply and data to the hybrid transformer 2 and the output signal of the main unit 1 to the terminal 3. A hybrid transformer 2 to be output, a terminal 3 which is driven by an output signal of the hybrid transformer 2 and exchanges data with the main unit 1, and is switched by a control signal of MICOM It consists of a switching unit 4 for turning on and off the power supply (VF) to the hybrid transformer (2).
이와 같이 구성된 본 고안의 작용, 효과를 첨부한 도면 제3도를 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to Figure 3 attached to the operation, effects of the present invention configured as described above are as follows.
먼저 주장치부(1)에서 출력된 전원 및 데이타는 하이브리드 트랜스(2)의 1차측(L1)에 인가되어 2차측(L2)(L3)으로 여기된다.First, the power and data output from the main unit 1 are applied to the primary side L1 of the hybrid transformer 2 and excited to the secondary side L2 and L3.
상기 하이브리드 트랜스(2)의 2차측(L2)(L3)으로 여기된 상기 주장치부(1)의 출력신호는 단말기(3)를 구동시키게 되고 이에 따라 상기 주장치부(1)와 상기 단말기(3)는 데이타를 교환하게 된다.The output signal of the main unit 1 excited to the secondary side L2 and L3 of the hybrid transformer 2 drives the terminal 3 and thus the main unit 1 and the terminal 3. Will exchange data.
이때 교환되는 데이타 값이 비정상일 경우에는 마이콤(MICOM)의 제어신호가 로우가 되어 스위칭부(4)를 오프시켜 상기 하이브리드 트랜스(2)에 전원(VF)공급을 차단시킴으로서 단말기(3)의 파워는 오프된다.At this time, if the data value to be exchanged is abnormal, the control signal of the MICOM becomes low, and the switching unit 4 is turned off to cut off the power supply VF to the hybrid transformer 2 to power the terminal 3. Is off.
이후 단말기(3)의 파워가 완전히 오프될때까기 일정 시간지연된 후 상기 마이콤(MICOM)은 하이신호를 스위칭부(4)에 출력하여 다시 스위칭부(4)를 온상태로 스위칭시켜 단말기(3)의 파워를 온 시킴으로써 상기 단말기(3)의 파워를 리세트 시키게 된다.After a certain time delay until the power of the terminal 3 is completely turned off, the MICOM outputs a high signal to the switching unit 4 to switch the switching unit 4 to the on state again. By turning on the power, the power of the terminal 3 is reset.
이상에서 설명한 바와 같이 본 고안은 단말기의 파워를 오프시킨 후 다시 온시켜 완전한 리세트를 행함으로써 단말기의 래치업 상태를 제거하여 동작의 신뢰도를 향상시키는 효과가 있다.As described above, the present invention has the effect of improving the reliability of the operation by eliminating the latch-up state of the terminal by turning the power off and then on again to perform a complete reset.
