Abstract
The invention discloses a cable checking device which comprises an emitter and a receiver, wherein 12 taps I are arranged on the emitter; one end of each tap I is connected with one alligator clip; the other end of each tap I is connected with the output end of a single chip microcomputer; the output end of the single chip microcomputer emits pulse signals with different frequencies; 12 taps II are further arranged on the receiver; one end of each tap II is connected with one alligator clip; the other end of the tap II is connected with the receiving end of the single chip microcomputer; the single chip microcomputer is connected with nixie tubes; the alligator clips of the emitter and the receiver are respectively connected with core wires at the two ends of a cable; the pulse signals emitted from the output end is sent to the receiving end at the other end of a cable through the core wires of the cable; the receiving end displays different digitals according to the different pulse signals transmitted by each core wire. According to the cable checking device, the output port of the single chip microcomputer is utilized to emit different pulse signals to the core wires of the cable, the cable checking operation can be realized without communication of an interphone, the condition of repeated short circuit and turn-off operations of an operator is avoided, moreover mistakes caused by communication are avoided, and the accuracy of the cable checking is improved.
Description
Technical field
The present invention relates to a kind of heart yearn school line apparatus, belong to electrical equipment technical field.
Background technology
In transformer station, there are many switch cubicles and equipment, need cable that these equipment and switch cubicle are connected.The independent second protection this part of the newly-built 110kv transformer station of picture obtains 300 substantially with cable, and these cable lengths differ, and short has more than 5 meters, and long may reach 200 meters.After these cables are removed the peel by device for peeling, the wire of remaining the inside, due to distance distant we do not know that wire is that root, our wire method of calibration used is exactly to need two to be skilled in technique to the clearly technician of good teamwork of drawing now, use intercom and multimeter, utilize the concentric lines such as shielding line at cable two ends, on one side by concentric line stube cable one end heart yearn, carry out school line by the method that multimeter need look for corresponding heart yearn to measure break-make at the other end on one side, therefore this method needs operating personnel repeatedly to communicate by letter and link up and repeatedly measure short circuit with intercom, opening operation, could confirm and circuit is carried out to mark, therefore operation is very complicated, and in real work, because operating personnel's skills involved in the labour are different, and operation is to carry out in noisy environment, therefore in communication work, make the mistake unavoidably and error, therefore often need butted line mistake to search and correct.And search wiring error and correct and can waste the plenty of time again, and then affect whole engineering and carry out smoothly.
Summary of the invention
Technical matters to be solved by this invention is the defect existing for prior art, and one heart yearn school line apparatus is easily provided.
For solving this technical matters, the invention provides a kind of school line apparatus, comprise emitter and acceptor two parts, described emitter is provided with 12 taps, carry out successively mark by 1-12 respectively, each tap one end is connected with a crocodile clip, and the other end connects the output terminal of a single-chip microcomputer, the pulse signal of output terminal transmitting different frequency; Described acceptor is also provided with 12 taps, and one end of each tap is connected with a crocodile clip, and the other end connects the receiving terminal of single-chip microcomputer, and single-chip microcomputer connects charactron; The crocodile clip of emitter and acceptor is the heart yearn at stube cable two ends respectively, the pulse signal of output terminal transmitting sends to the receiving terminal of the cable other end by the heart yearn of cable, the different pulse signals that receiving terminal transmits according to every heart yearn demonstrate the numeral that 1-12 is different on charactron.
Described emitter and acceptor be the case structure for being made up of engineering plastics all, has switch and charging inlet in case structure arranged outside.
Beneficial effect: the present invention utilizes single-chip microcomputer output interface to launch different pulse signals toward the heart yearn of cable, links up and can realize school line operation without intercom, has avoided repeatedly short circuit, disconnection work of operating personnel.And avoid communication to make the mistake, improve school line accuracy.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1 emitter, 2 acceptors, 3 crocodile clips, 4 switches, 5 charging inlets, 6 single-chip microcomputers, 7 charactrons, 8 cables.
Embodiment
Below in conjunction with drawings and Examples, the present invention is specifically described.
Figure 1 shows that structural representation of the present invention.
The present invention includes emitter 1 and acceptor 2 two parts.
Described emitter 1 is provided with 12 taps, carries out successively mark respectively by 1-12, and each tap one end is connected with a crocodile clip 3, and the other end connects the output terminal of a single-chip microcomputer 6, and output terminal is according to the pulse signal of the program transmitting different frequency of finishing.
Described acceptor 2 is also provided with 12 taps, and one end of each tap is connected with a crocodile clip 3, and the other end connects the receiving terminal of single-chip microcomputer 6, and single-chip microcomputer 6 connects charactron 7.
Crocodile clip 3 heart yearn at stube cable 8 two ends respectively of emitter 1 and acceptor 2, the pulse signal of output terminal transmitting sends to the receiving terminal of cable 8 other ends by the heart yearn of cable 8, the different pulse signals that receiving terminal transmits according to every heart yearn just can demonstrate the numeral that 1-12 is different according to the program of finishing on charactron.
Described unit sheet is 12, below tap, connects.
All case structures for being made up of engineering plastics of described emitter 1 and acceptor 2, its volume is 10cm*10cm*8cm.
There are switch 4 and charging inlet 5. in case structure arranged outside
Emitter 1 and acceptor 2 all use the battery of 5v to be used as power supply, and battery is rechargeable battery, and charging inlet 5 is internal battery charging, and battery is the power supply of unit sheet.
Further:
Lower right at equipment arranges wireless intercom equipment, just can realize two people's calls after plugging in the earphone, so just can be without wireless interspeaker, and whole school lineman only needs this equipment just can realize the functions such as school line, call, convenient and swift.
The present invention utilizes single-chip microcomputer output interface to launch different pulse signals toward the heart yearn of cable, links up and can realize school line operation without intercom, has avoided repeatedly short circuit, disconnection work of operating personnel.And avoid communication to make the mistake, improve school line accuracy.
The above-mentioned embodiment of the present invention, just illustrates, and is not only, and change within the scope of the present invention all or that be equal in scope of the present invention is all surrounded by the present invention.
