Description

The intelligence correcting line machine

Affiliated technical field

The utility model relates to a kind of instrument to polycore cable or bunched conductor two ends check and correction wire size.

Background technology

In the installation and maintenance of cable, the work that is absolutely necessary of school line, traditional is time-consuming bothersome again with examination lamp method school line.According to the result of understanding on the market and internet retrieval, in instrument, as be with digital the demonstration polycore cable or bunched conductor two ends check and correction wire size, need utilize 1 concentric line (or reference line), make troubles for like this use of instrument.The utility model without any need for concentric line, just can demonstrate the wire size of cable conductor by number in the check and correction wire size, also can be by clear and definite the demonstrating of charactron for short circuit, the open circuit fault of lead.

Summary of the invention

In order to proofread wire size not utilizing under the concentric line situation, this correcting line machine only arbitrarily presss from both sides last 1 lead with the black crocodile clip of instrument, the red crocodile clip of instrument is as long as folder is gone up arbitrarily 1 lead in addition so, and the 1 end wire size in addition of this root lead correspondence just shows by numeral on instrument immediately.

The technical scheme that its technical matters that solves the utility model adopts is: this intelligence correcting line machine is made up of two parts: sender unit and reception display.In the use, sender unit and reception display are placed on the two ends of polycore cable or bunched conductor respectively.

The sender unit technical scheme is: in insulation crust, the port that 16 numberings are arranged, each port is drawn the lead of 1 band crocodile clip, by crocodile clip with linked to each other by school lead one end, each port respectively connects 1 diode anode, serial connection 1 parallel voltage-stabilizing power supply integrated package behind the negative terminal short circuit of 16 diodes, this parallel voltage-stabilizing power supply integrated package provides power supply for other integrated package of sender unit.The negative terminal of this parallel voltage-stabilizing power supply integrated package connects 16 tunnel identical circuit, and this identical circuit is: connect with 1 diode anode after stabilivolt and the simulant electronic switch parallel connection.1 end (being the diode negative terminal) in addition of 16 tunnel identical circuit connects 16 ports respectively.Diode plays unidirectional conducting effect, and the control end of 16 simulant electronic switches comes from one group of pulse signal that sequential is arranged respectively.When certain two port formed a loop, because of the effect of a certain specific time sequence pulse signal, stabilivolt and simulant electronic switch parallel circuit produced one group of specific voltage drop like this, and this is reflected in port, and promptly port sends out the voltage signal of one group of specific time sequence.

Receiving the display technology scheme is: in insulation crust, draw two lines, black crocodile clamp and red crocodile clamp, black crocodile clamp output 15V DC voltage is given a certain port of sender unit, the voltage signal of 1 group of specific time sequence that send red crocodile clamp received signal transmitter another port.In insulation crust, the 15V dc power generating circuit is arranged, comparator circuit, single chip circuit and double figures sign indicating number pipe display circuit.The 15V direct current is as detecting ring current, comparator circuit receives red crocodile clamp signal and comparative voltage signal, generation is used for the logical signal of single-chip microcomputer identification, after single-chip microcomputer is accepted the logical signal of band sequential of comparer output, in software programming, find out by the school lead and whether open circuit or short circuit, and institute's corresponding lead wire size of 1 end in addition just often, single-chip microcomputer is exported to double figures sign indicating number pipe, and double figures sign indicating number pipe demonstrates concrete detection information.

The beneficial effects of the utility model are: can the one man operation, without any need for concentric line, just can show just to know whether open circuit by charactron extremely easily by the school lead, whether short circuit is black crocodile clamp and the short circuit of red crocodile live wire or red crocodile clamp and other lead short circuit; In the time of just knowing non-short interruption by the school lead in addition the wire size of 1 end what are.This utility model sender unit needs self-powered, and power supply provides by receiving display, can save battery-powered time greatly like this, prolongs battery serviceable life.The reception display of this utility model also can use as the break-make detecting device separately.For 16 above polycore cables or bunched conductor, can proofread step by step, also can be by increasing the disposable check and correction of method of sender unit quantity.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is circuit theory diagrams of the present utility model.

Embodiment

In the accompanying drawings, this intelligence correcting line machine is made up of two parts: sender unit and reception display.

Receiving display circuit is made up of 15V power supply, resistance R 1, R2, R3, R4, R5, comparer B1, B2, B3, single-chip microcomputer and double figures sign indicating number pipe.Black crocodile clamping connection+15V, red crocodile clip is D point serial connection R5 ground connection, and with B1+, B2+, B3-short circuit, after R1～R4 dividing potential drop, the A point connects B1's-, the B point connect B2-, the C point connect B3+, the output of comparer B1, B2, B3 is joined with input P1, P2, the P3 of single-chip microcomputer respectively, and single-chip microcomputer is exported to double figures sign indicating number pipe.

Sender unit has the port of 16 numberings, each port is drawn the lead of 1 band crocodile clip, by crocodile clip with linked to each other by school lead one end, each port respectively connects 1 diode anode, serial connection 1 parallel voltage-stabilizing power supply integrated package MAX6330 behind the negative terminal short circuit of 16 diodes, this parallel voltage-stabilizing power supply integrated package provides power supply VCC to sequential circuit.The circuit that the negative terminal GND termination 16 tunnel of this parallel voltage-stabilizing power supply integrated package is identical, this identical circuit is: stabilivolt Wn (n=1～16) connects with 1 diode anode with simulant electronic switch Kn (n=1～16) back in parallel.1 end (being the diode negative terminal) in addition of 16 tunnel identical circuit connects 16 ports respectively.Diode plays unidirectional conducting effect.The control end of 16 simulant electronic switches meets the output terminal Qn (n=1～16) of sequential circuit respectively, and output terminal Q1～Q16 produces 1 group of pulse signal that sequential is arranged respectively.Sequential circuit is by 555 time base circuits, decade counter, and d type flip flop, some and door, some not gates are formed.
