K5 puts the detection position of opening circuit selector switch.15,9 of K5 connects and continues to give BG5, the monostable circuit power supply that BG6 forms.13,16 of K5 disconnects, and short circuit indication luminotron D16, D17, D18, D19, D20 and the power cathode of each bar heart yearn disconnect.12,16 of K5 connects, and connection terminal X0 connects power cathode by resistance R 13, and resistance R 13 is the current-limiting resistances that open circuit and use when detecting.After operating switch K1 pushed a position, put the working position again, it is identical when at this moment the ring distributor principle of work of being made up of four d type flip flops is with short-circuit detecting, the output terminal Q1 of trigger D1 is a noble potential, the BG1 conducting, electric current opens circuit through Line 1 and indicates luminotron D11, main frame connection terminal X1, No. 1 heart yearn, 12,16 of connection terminal X6, the red luminotron D21 of secondary machine, green luminotron D30, X10, X0, R13, K5 gets back to power cathode, this moment, open circuit D21, the D30 of pilot lamp D11 and secondary machine of Line 1 lighted, and the indication operator: Line 1 does not open circuit.Suppose that Line 1 opens circuit, then the electric current sent of BG1 does not have path, and the Line 1 indication luminotron D11 that opens circuit can not light, and No. 1 heart yearn of indication operator opens circuit.Line 1 detects and to finish, and presses test button, continues to detect No. 2 lines, No. 3 lines, No. 4 lines, and that is not lighted the indication luminotron D12 that opens circuit of these three heart yearns, D13, D14 when detecting, and just illustrates that this heart yearn opens circuit, otherwise with regard to path.If do not light at the indication luminotron that opens circuit of finding No. 1, No. 2, No. 3, No. 4 heart yearn when detecting that opens circuit, may be that No. 0 heart yearn opens circuit, can be confirmed by the detection method that begins to tell about after other heart yearn and No. 0 line exchange.
(3) to line
To opening circuit detecting before the line or the heart yearn of short circuit is got rid of, intact heart yearn is numbered, receive successively on the connection terminal of main frame.If connection terminal connects discontented (being that heart yearn lacks than connection terminal), can let alone does not emptyly influence line, but note must be by heart yearn is arranged on the connection terminal X0.Originally the heart yearn that connect on the secondary machine can be motionless, treat behind the intact line, remaining heart yearn be exactly open circuit, the heart yearn of short trouble.
For the convenience of narrating, suppose that five heart yearns of cable LX all are intact, wiring that just can be when detecting is constant, begins line.
Selector switch K5 is put line position, and 15,11 of K5 connects, and control end E2, the E3 of electronics two-way switch K2, K3, K4, E4 obtain noble potential, K2, K3, K4 conducting.15 and 9,10 of K5 disconnects, and monostable circuit loses power supply, and trigger end C1, the C2 of d type flip flop D1, D2, D3, D4, C3, C4 are by resistance R 22 ground connection.16,14 of K5 connects, and No. 0 the line connection terminal directly connects power cathode.
Operating switch is pushed into the working position in the set position earlier again, gives four d type flip flop set again.The operator finished weak point, opened circuit and detect and to the preliminary work of line this moment.Can leave the main frame one of cable and bring in secondary machine end, this moment, trigger D1 was set, output terminal Q1 is a noble potential, the BG1 conducting, electric current through luminotron D11(D11 this moment as relay indicating light, for double during to line, the host service function person observe to line process with), main frame connection terminal X1, No. 1 heart yearn flow to secondary machine.Suppose that this end of secondary machine of No. 1 heart yearn still receives on the connection terminal X6, then electric current is again through the red luminotron D21 of secondary machine, green luminotron D30(supposes that still No. 0 line is connected on the connection terminal X10 of secondary machine), X10, No. 0 heart yearn, X0,14 of K5,16 get back to power cathode, at this moment the operator can see that a red luminotron and a green luminotron of secondary machine are lighted, can confirm that the heart yearn that is connect on the pairing connection terminal X10 of the green luminotron of being lighted is exactly No. 0 line, the heart yearn that is connect on the pairing connection terminal X6 of the red luminotron of being lighted is a Line 1, and the heart yearn that is connect on the pairing connection terminal X6 of the red luminotron of being lighted is a Line 1.At this moment, the anodal current potential of secondary OLED D21 is 4 volts, and by X6, No. 1 heart yearn, X1, dropping resistor R5, electronic switch K2 deliver to the set end S2 of trigger D2.To the trigger D2 of 12V power supply, what set end S2 accepted is electronegative potential, so the state of trigger D2 when still keeping initial set, and output terminal Q2 is an electronegative potential.After the operator confirms Line 1, can take off the connection terminal X6 of Line 1, and put the wire size cover from secondary machine.After No. 1 disconnection, the set end S2 of trigger D2 no longer is subjected to the clamper of light emitting diode D21, D30, and the noble potential that acceptance is sent here through resistance R 5, electronic switch K2 from the negative pole of luminotron D11, the output terminal Q2 of trigger D2 is set and is noble potential.After Q2 becomes noble potential by electronegative potential, make the reset terminal R1 of trigger D1 be in noble potential by diode D8 on the one hand, trigger D1 is resetted, output terminal Q1 becomes electronegative potential, and BG1 ends, and Line 1 work indication luminotron D11 extinguishes No. 1 heart yearn dead electricity.The noble potential of Q2 provides base bias by resistance R 2 to BG2 on the other hand, makes it by by becoming conducting, and then electric current indicates luminotron D12, X2, No. 2 heart yearns to flow to secondary machine by No. 2 linemans.The other end of supposing No. 2 lines is connected on the connection terminal X7 of secondary machine, and then through X7, red luminotron D23, green luminotron D30, X10, No. 0 line, 14,16 of X0, K5 gets back to power cathode to electric current again.Therefore, when the operator removes Line 1 from secondary machine after, the red luminotron that is certain to see original Line 1 correspondence extinguishes and has a red luminotron to be lighted, and the heart yearn that connects is No. 2 lines on the pairing connection terminal of its indication this red luminotron of being lighted of operator.The operator takes off No. 2 lines from secondary machine, put the wire size cover.Identical with the principle after Line 1 picked-off, the output terminal Q3 of trigger D3 is changed to noble potential, and the output terminal Q2 of trigger D2 becomes electronegative potential, and the work indication luminotron D13 of No. 2 lines extinguishes, and No. 3 the lineman indicates luminotron D13 to light.Same operator can see that No. 2 pairing red luminotrons of line extinguish on the secondary machine, and there is a red luminotron to be lighted, the heart yearn that is connect on its indication this red luminotron of being lighted of operator pairing connection terminal is No. 3 lines, by that analogy, up to intact all heart yearns.
Need to prove, to line the time, four d type flip flops are no longer worked in the mode of ring distributor, purpose is in order to prevent because external interference or operator make the upset of trigger mistake doing the pulse that may occur when plucking the line action, and adopt the set end to force the method for set, solution fundamentally improves the reliability of line connector work to the problem of heart yearn branch feeding.
