School line apparatus
Technical field
The utility model relates to a kind of heart yearn school line apparatus, belongs 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 drawing technician of good teamwork clearly now, use intercom and multimeter, at cable two ends, utilize the concentric lines such as shielding line, on one side by concentric line stube cable one end heart yearn, by the method that multimeter need look for corresponding heart yearn to measure break-make at the other end, carry out school line 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 problem to be solved in the utility model is the defect existing for prior art, and a kind of heart yearn easily school line apparatus is provided.
For solving this technical matters, the utility model provides a kind of school line apparatus, comprise emitter and acceptor two parts, described emitter is provided with 12 taps, by 1-12, carry out successively mark 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 by engineering plastics all, in case structure arranged outside, has switch and charging inlet.
Beneficial effect: the utility model 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 operating personnel repeatedly short circuit, disconnection work.And avoid communication to make the mistake, improve school line accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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 utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises 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.
The crocodile clip 3 of emitter 1 and acceptor 2 is the heart yearn at stube cable 8 two ends respectively, 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.
Described emitter 1 and acceptor 2 be the case structure for being made by engineering plastics all, and its volume is 10cm*10cm*8cm.
In case structure arranged outside, there are switch 4 and charging inlet 5.
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 school line, and the functions such as call are convenient and swift.
The utility model utilizes single-chip microcomputer output interface to launch different pulse signals toward the heart yearn of cable, without intercom, links up and can realize school line operation, has avoided operating personnel repeatedly short circuit, disconnection work.And avoid communication to make the mistake, improve school line accuracy.
The above-mentioned embodiment of the utility model, just illustrates, and is not only, all within the scope of the utility model or the change being equal in scope of the present utility model all by the utility model, surrounded.
