본 발명은 현장에 가지 않고서도 전화기통화로써 교환기의 고장상태를 진단할 수 있게한 교환기의 고장진단방법에 관한 것이다.The present invention relates to a method for diagnosing a failure of an exchange that enables diagnosing a failure state of the exchange by telephone communication without going to the field.

종래의 교환기 고장진단방법은 교환기 고장 현장으로 직접 나가 교환기의 고장상태를 진단하게 되어 있었다. 그러나, 이 고장진단방법에 있어서는 고장진단요원이 고장현장으로 직접나가 고장상태를 진단하게 되므로 출장비가 증가하게되고, 고장진단에 많은 시간이 소요되며, 고장수리에 필요한 대체부품의 점수에 많은 시간이 소요되고, 이에따라 신속한 유지보수가 안되어 교환기 가입자이게 불편함을 주게되고 유지보수비가 증가되는 결점이 있었다.The conventional method for diagnosing a failure of an exchange was to go directly to the exchange failure site to diagnose a failure state of the exchange. However, in this failure diagnosis method, since the trouble diagnosis agent goes directly to the failure site and diagnoses the failure condition, the travel cost is increased, a lot of time is required for failure diagnosis, and a lot of time is required for the score of the replacement parts necessary for troubleshooting. There was a drawback in that it was not necessary for the rapid maintenance and thus the inconvenience to the subscribers of the exchange and the increase in the maintenance cost.

또한 제1도에 도시한 바와같은 RMS방식을 이용하여 원거리에서도 교환기의 고장상태를 진단할 수 있으나, 이는 프로그래머블 콘트롤러(11) 및 모뎀(12)(13)이 필요하게 되므로 그 프로그래머블 콘트롤러(11)를 조작할 줄 아는 조작자가 필요하게 되고, 교환기(14)까지 연결할 전송선이 필요하게 되어 설치비가 상승되고, 특히 프로그래머블 콘트롤러(11)가 설치되어 있지 않는 지역에서는 프로그래머블 콘트롤러(11)를 이동시켜 설치한 후 교환기(14)의 고장상태를 진단해야하므로, 고장진단 시간이 많이 소비되어 신속한 유지보수가 되지않고, 유지보수비가 상승되는 결점이 있었다.In addition, it is possible to diagnose the failure state of the exchanger at a long distance by using the RMS method as shown in FIG. An operator who can operate the controller is required, and a transmission line to be connected to the exchanger 14 is required, and the installation cost is increased. In particular, in an area where the programmable controller 11 is not installed, the programmable controller 11 is moved and installed. Since the failure state of the exchanger 14 needs to be diagnosed, the failure diagnosis time is consumed a lot, so that the maintenance cost is not increased and the maintenance cost is increased.

본 발명은 이러한 문제점을 해결하기 위하여, 어느 지역에서나 미리 예약시켜 놓은 고장진단용 비밀전화번호로 고장난 교환기에 전화를 걸어 교환기의 고장상태를 톤신호로 진단할 수 있게 창안한 것으로, 이를 첨부된 본 발명의 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the problem, the present invention is to make a call to a failed exchange with a trouble-preventing secret telephone number reserved in any area to diagnose a failure state of the exchange by a tone signal. Referring to the drawings in detail as follows.

제2도는 본 발명의 교환기 고장진단방법이 적용될 블록도로서, 이에 도시한 바와같이 국선가입자회로(3) 및 내선가입자회로(4)를 중앙제어장치(1)의 제어를 받는 스위칭회로(6)를 통하여 톤신호발생회로(5) 및 복합주파수 송수신회로(7)에 연결하고, 상기 각종회로의 제어 및 고장유무를 진단하기 위한 프로그램내용이 기억된 메모리회로(2)를 상기 중앙제어장치(1)에 연결되어 구성한다.2 is a block diagram to which the switch fault diagnosis method of the present invention is to be applied, and as shown therein, a switching circuit 6 which is controlled by the central controller 1 by the trunk subscriber circuit 3 and the subscriber subscriber circuit 4. Connected to the tone signal generation circuit 5 and the complex frequency transmission / reception circuit 7 and storing a memory circuit 2 storing program contents for diagnosing the control and failure of the various circuits. ) To configure.

제3도는 본 발명의 교환기 고장진단방법 흐름도로서, 이에 도시한 바와같이 스위칭회로(6)를 통하여 국선가입자회로(3) 또는 내선가입자회로(4)로부터 전화번호를 수신한다. 즉, 국선가입자회로(3) 또는 내선가입자회로(4)에서 출력된 전화번호신호는 스위칭회로(6)를 통해 복합주파수송수신회로(7)에 수신되고, 이와같이 복합주파수 송수신회로(7)에 수신된 전화번호를 중앙제어장치(1)에서 읽어 그 전화번호가 일반가입자 번호이면 메모리회로(2)에 프로그램된 내용에 의해 통상의 가입자 처리방법대로 가입자 처리하고, 그 전화번호가 예약된 비밀전화번호이면 메모리회로(2)에 프로그램된 내용에 의해 스위칭회로(6)를 통해 톤신호발생회로(5)에서 특정의 톤신호를 발생시킨후 그 톤신호를 스위칭회로(6)를 통해 국선가입자회로(3) 또는 내선가입자회로(4)로 보내어 통화자에게 고장진단할 사항을 알려달라고 알린다. 이후 통화자로부터 국선가입자회로(3) 또는 내선가입자회로(4)로 입력되는 고장진단사항을 상기와 같이 스위칭회로(6)를 통해 복합주파수 송수신회로(7)에서 재차 수신하며, 이때 중앙제어장치(1)에서 그 복합주파수 송수신회로(7)에 수신된 고장진단사항이 메모리회로(2)에 기억되어 있는 프로그램의 내용에 따라 스위칭회로(6)의 진단인가, 국선가입자회로(3) 및 내선가입자회로(4)의 진단인가, 메모리회로(2)의 진단인가, 복합주파수 송수신회로(7)의 진단인가, 통화협의회로의 진단인가 또는 가입자 정보를 수정하라는 진단인가등 진단할 사항을 차례로 점검하면서 고장진단사항이 이에 해당될 경우 메모리회로(2)에 기억되어 있는 종래의 고장진단 프로그램을 읽어 해당진단장치가 사용중인가를 점검한다.3 is a flowchart of a switch fault diagnosis method according to the present invention, and as shown therein, a telephone number is received from a trunk line subscriber circuit 3 or an extension subscriber circuit 4 through a switching circuit 6. That is, the telephone number signal output from the trunk line subscriber circuit 3 or the subscriber station circuit 4 is received by the composite frequency transmission / reception circuit 7 through the switching circuit 6, and thus received by the composite frequency transmission / reception circuit 7 in this manner. If the telephone number is read from the central control unit 1, and the telephone number is the general subscriber number, the subscriber is processed according to the normal subscriber processing method according to the contents programmed in the memory circuit 2, and the secret telephone number is reserved. After the specific tone signal is generated in the tone signal generation circuit 5 through the switching circuit 6 according to the contents programmed in the memory circuit 2, the tone signal is transmitted through the switching circuit 6. 3) Or, it is sent to the subscriber circuit 4 to inform the caller of the problem to be diagnosed. Thereafter, the fault diagnosis input from the caller to the trunk line subscriber circuit 3 or the internal subscriber circuit 4 is received again by the composite frequency transmission / reception circuit 7 through the switching circuit 6 as described above. Is the diagnosis of the switching circuit 6 according to the contents of the program stored in the memory circuit 2, or the fault diagnosis received by the composite frequency transceiver circuit 7 in (1)? Check the items to be diagnosed in order, such as diagnosis of the subscriber circuit 4, diagnosis of the memory circuit 2, diagnosis of the composite frequency transceiver circuit 7, diagnosis of the call consultation circuit, or diagnosis of correction of subscriber information. If the fault diagnosis item corresponds to this, the conventional fault diagnosis program stored in the memory circuit 2 is read to check whether the diagnosis device is in use.

이때 진단장치가 사용중이 아니면 고장진단을 수행토록한 후 그 결과에 따라 상기와 같이 톤신호 발생회로(5)에서 특정의 톤신호를 발생시킨후 그 특정의 톤신호를 스위칭회로(6)를 통하여 국선가입자회로(3) 또는 내선가입자회로(4)로 보내어 통화자에게 고장진단결과를 알리며, 해당진단장치가 사용중이면 상기와 같이 톤신호발생회로(5)에서 화중음신호를 발생시킨 후 그 화중음신호를 스위칭회로(6)를 통하여 국선가입자회로(3) 또는 내선가입자회로(4)로 보내게한다. 한편, 상기 톤신호발생회로(5)에서 발생되는 톤신호는 발신음, 보류음, 호출음, 멜로디음, 화중음등이 있다.At this time, if the diagnostic apparatus is not in use, it is allowed to perform a fault diagnosis and according to the result, the tone signal generating circuit 5 generates a specific tone signal as described above, and then sends the specific tone signal through the switching circuit 6. It sends to the CO line subscriber circuit (3) or the internal subscriber circuit (4) to inform the caller of the result of the failure diagnosis. If the corresponding diagnosis device is in use, the tone signal generation circuit (5) generates a busy tone signal as described above. The middle tone signal is sent to the trunk line subscriber circuit 3 or the internal subscriber circuit 4 through the switching circuit 6. On the other hand, the tone signal generated by the tone signal generation circuit 5 includes a dial tone, a hold tone, a call tone, a melody tone, a call tone, and the like.

이상에서와 같이 본 발명은 교환기의 고장상태를 전화를 걸어 특정톤신호로 진단하게 되므로, 교환기의 고장진단이 대단히 손쉽게 이루어짐과 동시에 고장진단시간이 극히 짧게 소요되고, 이에따라 교환기의 유지보수가 손쉽고, 유지보수시간이 단축되며, 교환기의 가입자에게 신뢰감을 부여할 수 있게 되는 이점이 있게 된다.As described above, the present invention makes a diagnosis of a specific tone signal by dialing a failure state of the exchanger, which makes the diagnosis of the exchanger very easy and at the same time takes a very short troubleshooting time, thereby making maintenance of the exchange easy, The maintenance time is shortened and there is an advantage that can give a trust to the subscriber of the exchange.
