본 고안은 전화선로내에 고장이 발생할경우 전화국에서 원격제어하여 정확한 고장의 원인과 고장이 발생한 구간(예컨데 가입자측 책임구간과 전화국측 책임구간)을 즉시로 판별하게된 전화선로제어기에 관한 것이다.The present invention relates to a telephone line controller in which a telephone station remotely controls the telephone line to remotely determine the exact cause of the failure and the section in which the failure occurs (for example, the subscriber side and the telephone station side).

주지된 바와같이 현재 전화국에서는 자체내 자동시험기등으로 가입자선로를 매일점검하거나 전화가입자로부터 신고에 의해 이상의 유무를 확인하고 유지보수를 행하였던바, 이는 일단 고장발생이 확인되면 수리원이 출동하게되나 정확한 고장의 구간을 인지하기가 곤란하므로 수리원이 경험에 의해 일일히 점검을 행한후 고장구간을 판별하여 수리케되었기 때문에 많은 인력과 시간이 요구하게됨에 따라 특히 가입자의 회선과 전화회선을 이용한 기기들이 급중하게 되어 더욱 수리원이 출동 수리하는 서비스로는 이를 충당할수가 없었다.As is well known, the current telephone company checked the subscriber line every day with its own automatic tester, or checked the abnormality by maintenance from the telephone subscriber, and performed the maintenance. Since it is difficult to recognize the section of the fault, the repair worker checked the experience and then repaired it by identifying the fault section. As a result, a lot of manpower and time are required. As a result, they were unable to cover this with service provided by repair workers.

또한 통상 가입자측의 건물(주택)내테서 발생한 고장은 그 유지보수의 책임이 가입자측에 있게되고 그 외의 고장은 전화국측에서 책임을 지게되나 이러한 고장발생 구간을 전화국내에서는 판별하기가 불가능하였다.In addition, in case of a failure occurring in a subscriber's building (home), the maintenance of responsibility is at the subscriber's side, and other failures are held at the subscriber's office.

따라서 종래에도 상기의 문제를 조금이나마 해소코져 안출된것이 있었다.Therefore, some problems have been devised in the past.

즉 제1도에서와 같이 가입자측과 국선측의 경계점을 분리시키지않고 가입자측의 기기와 병렬로 시험정항(Rx)을 설치하여 측정케 한 것으로 여기서 Rx는 선로의 등가 저항이고 T는 가입자의 전화기이다.That is, as shown in Fig. 1, the test point (Rx) was installed in parallel with the equipment of the subscriber side without separating the boundary between the subscriber side and the trunk line side, where Rx is the equivalent resistance of the line and T is the subscriber's telephone. to be.

제1도의 경우는 측정동작시에 일정저항치를 갖게되어 통화이 감도가 낮게되는 결점이 있으며 고장발생의 구간 식별이 단선사고에 한해서만 명확하게 되고 접지, 단락, 등의 고장과 외부전압유기등의 사고 발생시에는 별도의 측정기를 사용해야만 되는 문제가 있었다.In case of Fig. 1, there is a drawback that the call has low sensitivity because it has constant resistance value during measurement operation, and the identification of the fault section is clear only in case of disconnection, and in case of fault such as grounding, short circuit, etc. There was a problem that must use a separate meter.

본 고안은 상기의 제반문제를 해소코져 안출된 것으로, 전화국내의 시험대와 국선간에 다단의 접점을 갖은 제어전화스위치를 설치하고 가입측선로와 국선의 경계부에는 상기 제어전환스위치에 의해 전환구동케된 제어부를 간설하여서 고장발생유무의 시험시에 가입자측선로와 국선을 분리하여 시험케 된 것으로 단선, 단락, 접지 및 전압유기등의 고장원인과 고장의 발생구간을 정확히 판결하게 된 것으로서 도면에 의거 본 고안을 상세히 설명하면 다음과 같다.The present invention is designed to solve the above problems, install a control telephone switch having a multi-stage contact point between the test station and the trunk line in the telephone station, and the switching side switch and driven by the control switching switch at the boundary of the trunk line It is a test that separates the subscriber line and trunk line when testing for the occurrence of failure by judging the control unit, and accurately judges the cause of failure such as disconnection, short circuit, grounding, and voltage maintenance and the occurrence section of the failure. The invention is described in detail as follows.

제2도, 제3도에 있어서 1은 주지된 전화국내의 시험대이며 Lx1, Lx2는 시험대의 선로이다.In FIG. 2 and FIG. 3, 1 is a test stand in a well-known telephone station, and Lx1 and Lx2 are tracks of a test stand.

SW는 자동복귀되게된 제어전환스위치로 다단의 고정 접점(a,c,e,f,h,a',c',e',f',h')과 가동접점(b,d,g,b',d',g')으로 구성되고 가동접점편(S1)(S2)에 의해 각 접점(a,b…h,a',b'…h')의 접촉이 전환토록되며 어느측이나 온시키면 자동으로 원상복귀되게 된다.SW is a control switch that automatically returns to the multi-stage fixed contacts (a, c, e, f, h, a ', c', e ', f', h ') and movable contacts (b, d, g, b ', d', g '), and the contact of each contact a, b ... h, a', b '... h' is switched by the movable contact pieces S1 and S2. When turned on, it automatically returns to normal.

2는 주진된 코넥터로 전확국에서 가입자측으로 연결케된 국선(L1,L2)이 연결되었다.2 is the main connector to which the trunk lines (L1, L2) connected from subscriber stations to subscribers are connected.

3은 본 고안의 제어부로 전압검출회로(3a)와 제어회로 (3b)로 구성되고 2단 접점의 래치릴레이가 국선(L1)(L2)과 가입자선로(LT1)(LT2)의 경계부에 설치되었다.3 is a control unit of the present invention, which is composed of a voltage detection circuit 3a and a control circuit 3b, and a latch relay of two-stage contacts is installed at the boundary between the trunk lines L1, L2, and the subscriber line LT1, LT2. It became.

상기 제어전환스위치(SW)의 가동접점(b)과 고정 접점(f',c')이 전원 (Ba)의 (+)측에 연결되고, 가동접점(b')과 고정접점 (f,c)이 전원 (Ba)의 (-)측에 연결되었으며 가동접점(d),(g)는 고정접점(e'),(h')에 각각 연결되었다.The movable contact b and the fixed contacts f 'and c' of the control switching switch SW are connected to the (+) side of the power supply Ba, and the movable contact b 'and the fixed contact (f, c). ) Is connected to the (-) side of the power supply Ba, and the movable contacts (d) and (g) are connected to the fixed contacts (e ') and (h'), respectively.

또한 고정접점(e, h)는 각각 시험대(1)의 선로(Lx1,Lx2)에 연결되고 가동접점 (d',g')는 코넥터(2)에 연결되었으며 고정접점(a,a')는 각각 접지되었다.In addition, the fixed contacts (e, h) are respectively connected to the lines (Lx1, Lx2) of the test bench 1, the movable contacts (d ', g') are connected to the connector (2), and the fixed contacts (a, a ') Each grounded.

또한 초기에 접점()로, 접점()로 되고 접점(de)(gh)로 되어서 시험대(1)의 선로(Lx1,Lx2)는 각각 코넥터(2)를 통해 국선(L1)(L2)과 연결된다.Initially, the contacts ( ), Contacts ( ) And the contact point de (gh) so that the lines Lx1 and Lx2 of the test bench 1 are connected to the trunk lines L1 and L2 through the connector 2, respectively.

한편 제어부(3)의 전압검출회로(3a)는 제너 다이오드(ZD1)의 캐소드측에 캐소드가 연결된 2개의 다이오드(D1,D2)의 에노드가 가입자선로(LT1),(LT2)와 각각 연결되고 또 래치릴레이(도시치않음)의 접점(P1',P1)에 각각 연결되었다.On the other hand, the voltage detection circuit 3a of the controller 3 has an anode of two diodes D1 and D2 having a cathode connected to the cathode side of the zener diode ZD1 connected to the subscriber lines LT1 and LT2, respectively. And the contacts P1 'and P1 of the latch relay (not shown), respectively.

제너다이오드(ZD2)의 에노드측에 에노드가 연결된 2개의 다이오드(D3,D4)는 그 캐소드측이 접점 (P2)(P2')에 연결되고 캐소드의 양단에 시험저항(Rx)이 연결되었으며 래치릴레이의 공통접점(P,P')에는 각각 국선(L1)(L2)이 연결되어 초기에 접점(), 접점()으로 연결되었다.Two diodes (D3, D4) having an anode connected to the anode side of the zener diode (ZD2) have a cathode side connected to a contact point (P2) (P2 ') and a test resistance (Rx) connected to both ends of the cathode. CO lines L1 and L2 are connected to the common contacts P and P 'of the latch relay, respectively, ), Contact( ).

이와같이 연결구성된 본 고안은 평시에는 시험대(1)의 선로(Lx1)(Lx2)가 국선(L1)(L2)에 연결되게 되고 가입자선로(LT1)(LT2)에 연결케 되느데 회선의 시험 또는 고장발생시에는 제어전환스위치(SW)를 가동접점편(S2)으로 온시키면 가입자선로(LT1,LT2)와 국선(L1,L2)이 분리되게 된다.In this way, the present invention is configured such that the line Lx1 (Lx2) of the test bench 1 is connected to the trunk line L1 (L2) and connected to the subscriber line LT1 (LT2). In the event of a failure, turning on the control switch SW to the movable contact piece S2 separates the subscriber lines LT1 and LT2 and the trunk lines L1 and L2.

즉 제어전환스위치(SW)가 접점()에서 접점(f',g')으로 되고 접점()에서 접점()로 되어 국선(L1)(L2)에서 전원(Ba)의 (+)가 인가되고(-)는 접지되며 전압검출회로(3a)의 제너다이오드(ZD1)에는 그 항복전압보다 높은 전압이 인가되어서 곧 도통되고 이에따라 제어회로(3b)는 제어출력을 내보내어 래치릴레이가 접점() 접점()로 전환되어 국선(L1), 시험저항(Rx) 국선(L2)으로 연결되는 회로가 구성되게 되며 가입자 선로(LT1,LT2)는 개로되어 제2도와 같이 되는데 제어스위치(SW)는 곧 원상복귀되어 그 접점도 초기때와 같이 접촉된다.That is, the control changeover switch (SW) is a contact ( ) Becomes the contact (f ', g') and the contact ( ) At (+) Of the power supply Ba is applied from the trunk lines L1 and L2, (-) is grounded, and a voltage higher than the breakdown voltage is applied to the zener diode ZD1 of the voltage detection circuit 3a. Soon, the control circuit 3b outputs a control output so that the latch relay contacts ) Contact( ) And the circuit connected to the trunk line L1 and the test resistor Rx trunk line L2 is configured, and the subscriber lines LT1 and LT2 are opened and become as shown in FIG. 2, and the control switch SW returns to its original state. The contact is also in contact with the initial state.

이때에 시험대(1)에서는 통상과 같이 시험을 행하게 되는데 이와같이 가입자축과 전화국축을 분리시험하게 되므로 고장의 구간이 명확해진다.At this time, the test bench 1 performs the test as usual, but since the subscriber axis and the telephone station axis are separated and tested, the section of the failure becomes clear.

다시 회선을 원상복귀시키고자 할때는 제어전환스위치(SW)의 가동접점편(S1)을 온시키면 된다.When the circuit is to be restored, the movable contact piece S1 of the control changeover switch SW is turned on.

즉 접점으로 연결되어 전원(Ba)의 (+)측은 접지되고 (-)측은 국선(L1,L2)에 인가되어 래치릴레이의 접점()→다이오드(D3)로 래치릴레이의 접점()→다이오드(D4)로 인가되어 제너다이오드(ZD2)가 도통되고 제어회로(3b)의 출력이 바생되어 래치릴레이는 접점(), 접점(P' P1')으로 전환되어 가입자선로(LT1,LT2)와 국선(L1,L2)이 다시 연결되고, 제어전환스위치(SW)가 원상복귀되어 그 접점(a,b…h,a',b',…h')는 와 같이 된다.Contact The positive side of the power supply Ba is grounded and the negative side is applied to the trunk lines L1 and L2 so that the contact of the latch relay ( → The contact of the latch relay with the diode (D3) → Zener diode ZD2 is turned on and applied to diode D4, and output of control circuit 3b is generated. ), And the subscriber line (LT1, LT2) and the trunk line (L1, L2) are reconnected by switching to the contact point (P 'P1'), and the control changeover switch (SW) is returned to its original state and the contact points (a, b… h) , a ', b', ... h ') becomes

상기와 같이 본 고안은 작동되므로 전화회선의 고장발생시에 유지보수의 책임구간을 명확히 알 수 있으며 고장발생의 원인또한 정확히 인지케되고 평시에는 전화회선과는 전기적으로 완전분리되어 통화의 감도를 저하시키는 악영향이 없게된다.As the above design works, it is possible to clearly know the responsibilities of maintenance in case of failure of the telephone line, and the cause of the failure is also clearly recognized, and in normal times, it is electrically isolated from the telephone line, thereby reducing the sensitivity of the call. There is no adverse effect.

상술한 바와같이 본 고안은 기존의 시험대에 간단히 부설하고 국선과 가입자선로의 경계부에 제어부(3)를 설치하여서 전화국내에서 원격제어로 고장의 원인과 이에 따른 유지보수의 책임구간을 명확히 식별하게 되므로 일의 능률이 매우 높게되고 통신선로의 유지보수관리의 합리화를 이루게된 대단히 유용한 고안이다.As described above, the present invention simply installs the existing test bench and installs the control unit 3 at the boundary between the trunk line and the subscriber line, so that the cause of the failure and the maintenance section according to the remote control can be clearly identified within the telephone station. It is a very useful design that makes the work very efficient and the rationalization of maintenance of communication line.
