embodiment
[0008]from Fig. 1, Fig. 2, the present invention includes A device and B device, the A device comprises: the automatic end z ground connection of remote control and automatic selector switch S1, remote control end y connects power supply by resistance R 1, the input end of center termination the first not gate F1 and the second Sheffer stroke gate YF2, the input end of output termination the first Sheffer stroke gate YF1 of the first not gate F1, another input termination multivibrator 1 of the first Sheffer stroke gate YF1, the output termination counter 2 of the first Sheffer stroke gate YF1, another input end of the second Sheffer stroke gate YF2 connects power supply by resistance R 2, also by the pushbutton switch S2 ground connection of connecting with the remote control reception normally closed contact Sx of remote-control receiving circuit 5, the output terminal of the second Sheffer stroke gate YF2 is connected to the input end of monostalbe trigger 3, the output terminal of monostalbe trigger 3 sum counters 2 also is connected to the input end of shift register 6, the output terminal of the Ds termination trigger flip-flop 4 of shift register 6, the lowest order output terminal Q0 of shift register 6 meets the reset terminal R of trigger flip-flop 4, the n road output of shift register 6 is protected output circuit to be connected to by indication and is treated each heart yearn one end of school cable, the CP of trigger flip-flop 4 triggers the output on last road of termination (i.e. n road), treat the shielding line ground connection of school cable, the B device comprises: the automatic end z ground connection of remote control and automatic selector switch S3, remote control end y connects power supply by resistance R 3, the input end of center termination the second not gate F2 and the 4th Sheffer stroke gate YF4, the input end of output termination the 3rd Sheffer stroke gate YF3 of the second not gate F2, another input termination multivibrator 8 of the 3rd Sheffer stroke gate YF3, the output termination counter 9 of the 3rd Sheffer stroke gate YF3, another input end of the 4th Sheffer stroke gate YF4 connects power supply by resistance R 4, also by the pushbutton switch S4 ground connection of connecting with the remote control reception normally closed contact Sy of remote-control receiving circuit 12, pushbutton switch SF controls the signal emission of remote controlled transmitting circuit 15, the output terminal of the 4th Sheffer stroke gate YF4 is connected to the input end of monostalbe trigger 10, the output terminal of monostalbe trigger 10 sum counters 9 also is connected to the input end of shift register 13, the output terminal of the Ds termination trigger flip-flop 11 of shift register 13, shift register 13 lowest order output terminal Q0 meet the reset terminal R of trigger flip-flop 11, the n road output of shift register 13 is connected to the n road wire size indicator light circuit corresponding with the A device, the CP of trigger flip-flop 11 triggers the output on last road of termination (i.e. n road).
As checked the polycore cable of X, Y two places, the A device is placed in to X ground, and the B device is placed in Y ground, at first on X ground, will treat the output terminal of the n root line in school and A device 1. 2. 3. 4. ... n connects respectively complete, the shielding line of polycore cable connects the ground wire of A device, then to Y ground, carries out verification.When this device starts, shift register, counter, monostalbe trigger be clear " 0 " all, trigger flip-flop set, the original state that Here it is installs.
If the center-side of remote control and automatic selector switch S1 switch is connected to automatic end z, this device just is placed in automatic mode, electronegative potential is added to the input end of not gate F1, not gate F1 output high level is opened Sheffer stroke gate YF1, the oscillating impulse that multivibrator 1 produces adds to counter 2 by Sheffer stroke gate YF1 continually, when counter 2 adds to full one state, next count pulse will produce a carry signal in to counter clear " 0 ", this carry signal is exactly the shift signal of shift register 6, because the Ds of shift register 6 terminates at the output terminal of trigger flip-flop 4, it is now high level, under the effect of the carry pulse of counter 2, the lowest order end Q0 output high level of shift register 6, by indication, protect output circuit to make 1. to hold and be one state, another effect of lowest order end Q0 output high level is exactly to trigger flip-flop 4 clear " 0 ", to avoid follow-up carry pulse that the high level of trigger flip-flop 4 is transferred to shift register 6.In like manner under the effect of second carry pulse; the high level of shift register moves to right; by indication, protect output circuit to make 1. to hold and be " 0 " state; 2. end is one state; each carry pulse makes shift register move to right one; that is the transfer of the one state of output once, until school toe-in bundle.
If the center-side of remote control and automatic selector switch S1 switch is connected to remote control end y, this device just is placed in remote control (manually) duty, the center-side of remote control and automatic selector switch S1 adds to Sheffer stroke gate YF2 by high level opens it, high level blocks Sheffer stroke gate YF1 by the level "0" of not gate F1 output simultaneously, and the pulse of multivibrator 1 can not add to counter 2 by Sheffer stroke gate YF1.The self checking switch that pushbutton switch S2 is the A device.If now press the pushbutton switch SF of lower B device, remote controlled transmitting circuit 15 provides a remote signal on the one hand, A, after the remote-control receiving circuit 5 of B stream oriented device and 12 receives, with normally closed pushbutton switch S2, the remote-control receiving circuit 5 of S4 series connection and 12 remote control reception normally closed contact Sx, Sy all opens once, by Sheffer stroke gate YF2 and YF4 to monostalbe trigger 3 and 10 1 trigger pulses, after integer as the shift signal of shift register 6, make the lowest order end Q0 output high level of shift register, make 1. to hold by output and holding circuit and be one state, 1. the end pilot lamp of B device is bright simultaneously.Another effect of lowest order end Q0 output high level is exactly to trigger flip- flop 4 and 11 clear " 0 ", to avoid follow-up carry pulse, the high level of trigger flip-flop is transferred to shift register.As the pushbutton switch SF that again presses lower B device; second pulse of monostable circuit output of A device; make the high level of shift register move to right again one; make 1. to hold by protection and output indicator circuit and be " 0 " state; 2. end is one state; often press the pushbutton switch S4 of lower B device once, A device shift register moves to right one, until n root line school line all finishes later.
The B device is except following 2, and circuit even components and parts is all identical with the A device: B device pushbutton switch SF controls remote controlled transmitting circuit 15; The output of the shift register 13 of a B device Line connecting number pilot lamp, do not connect polycore cable, and the A device has complete indication protection output circuit, and output connects an end of polycore cable.
B device and A device control circuit and principle of work are basic identical, and strict synchronous, when A device output when 2. end is one state, 2. number pilot lamp of B device is bright, can see the bright cresset of indication of B device on Y ground, survey Y ground with multimeter and hold and treat that each heart yearn of school cable, the heart yearn that is high level are exactly 2. number line, shielding line connects the multimeter negative pole.
