Description
Technical field
The present invention relates to a kind of device of full tandem test netting twine break-make, the break-make that can test netting twine, each netting twine of identification between netting twine distributing frame and terminal network line socket belongs to network communications technology field in view of the above.
Background technology
" electronic measurement technique " 2004 (1) published one piece and has been entitled as the document of " based on single-chip microcomputer network cable tester circuit ", and the disclosed a kind of netting twine proving installation of the document is made up of main circuit and auxiliary circuit two parts.Main circuit is made up of AT89C51 single-chip microcomputer, test signal distributor circuit, test signal testing circuit, seven segment digital tubes display circuit, BCD decoding and driving circuit.Auxiliary circuit is made up of diode display circuit and winding circuit.Test signal distributor circuit in the main circuit has route selection and feed function.It periodically selects in turn according to the order of sequence and receives each root in eight heart yearns in the tested netting twine, and presents test signal high level " 1 " to it.Test signal is transferred to the netting twine other end through certain heart yearn, and is sent to auxiliary circuit.Auxiliary circuit shows the loopback of each heart yearn in the netting twine, cooperates main circuit to accomplish test job.Test signal by the auxiliary circuit loopback after, transmit back main circuit through other heart yearn again.The test signal testing circuit cycle gathers the signal on other seven heart yearns in turn, if collect high level " 1 ", it is normal to explain that then certain heart yearn is communicated with, otherwise connects bad.The route selection cycle of test signal distributor circuit should guarantee that the test signal testing circuit detects once respectively the signal on other seven heart yearns at least.Seven segment digital tubes display circuit shows signal collection result shows the break-make situation of every heart yearn.In fact,,, all need eight heart yearns all be connected with a new crystal head again, perhaps change whole netting twine no matter the junction that off position is positioned at crystal head still is certain position of heart yearn self no matter eight which roots of heart yearn open circuit in netting twine.And a kind of like this function that can detect eight which root break-makes of heart yearn in the netting twine makes that this netting twine proving installation complex structure, cost are high, carry inconvenience, also lacks practical significance simultaneously.
The utility model content
Its purpose of the utility model is to propose a kind of simple in structure, netting twine proving installation that cost is low, easy to carry; Through complete in-line simple operations mode; Test any heart yearn break-make situation in the netting twine, thereby need to judge whether the reclosing crystal head in view of the above or change this netting twine.For this reason, we have invented a kind of device of full tandem test netting twine break-make.
The utility model is characterized in that; See shown in Figure 1; LED is connected between A netting twine socket a1 pin and the direct supply EC positive pole; Resistance R is connected between A netting twine socket a8 pin and the direct supply EC negative pole, A netting twine socket a2 pin and a3 pin, a4 pin and a5 pin, a6 pin and the conducting in twos of a7 pin; B netting twine socket b1 pin and b2 pin, b3 pin and b4 pin, b5 pin and b6 pin, b7 pin and the conducting in twos of b8 pin.
Its technique effect of the utility model is; See shown in Figure 2; The crystal head at netting twine to be measured two ends is A1 crystal head and B1 crystal head; Eight lead-in wires of A1 crystal head are 1a lead-in wire, 2a lead-in wire, 3a lead-in wire, 4a lead-in wire, 5a lead-in wire, 6a lead-in wire, 7a lead-in wire, 8a lead-in wire; Eight lead-in wires of B1 crystal head are 1b lead-in wire, 2b lead-in wire, 3b lead-in wire, 4b lead-in wire, 5b lead-in wire, 6b lead-in wire, 7b lead-in wire, 8b lead-in wire, and eight heart yearns of netting twine to be measured are connected to 1a lead-in wire and 1b lead-in wire, 2a lead-in wire and 2b lead-in wire, 3a lead-in wire and 3b lead-in wire, 4a lead-in wire and 4b lead-in wire, 5a lead-in wire and 5b lead-in wire, 6a lead-in wire and 6b lead-in wire, 7a lead-in wire and 7b lead-in wire, 8a lead-in wire and 8b lead-in wire between any two.The A1 crystal head is inserted in the A netting twine socket, the B1 crystal head is inserted in the B netting twine socket, this moment, eight heart yearns of netting twine to be measured were series connected; And constitute a loop with LED, direct supply EC, resistance R in the device of the test netting twine break-make of the utility model; If said eight equal conductings of heart yearn, then LED is lighted, as long as said eight heart yearns have a heart yearn to open circuit; Then LED is not luminous, judges the break-make of netting twine to be measured in view of the above.It is thus clear that adopting the device of the test netting twine break-make of the utility model is the break-make of testing netting twine with the mode of full series connection very simply and easily.When the test netting twine when opening circuit, be that which root heart yearn opens circuit though can not test out,, proceed from the reality, for this situation, all be to remove original crystal head, connect new crystal head again, perhaps adopt a new whole fault netting twine of netting twine replacement.When realizing simple and convenient test; Because this device amounts to five parts through simply being electrically connected to form by LED, A netting twine socket, direct supply EC, resistance R and B netting twine socket altogether; Therefore, structure obtains simplifying, and cost also significantly reduces; Volume is little, in light weight, carries, uses very convenient.
One of the utility model subsidiary effect is can be used between netting twine distributing frame and all terminal network line sockets, discerning each netting twine.Owing to concentrate the many netting twines crystal head of an end separately at netting twine distributing frame place; The other end of every netting twine is connected with a terminal network line socket respectively; Between these terminal network line sockets away from the netting twine distributing frame; And the position is different, and which terminal network line socket the other end that need check some its netting twines that is connected of crystal head at netting twine distributing frame place sometimes is connected to.The device of the test netting twine break-make of employing the utility model can be accomplished this at an easy rate and check task, and details are as follows.Get intact, short two ends and be connected with the netting twine of crystal head, a crystal head inserts a terminal network line socket, the B netting twine socket in the device of the test netting twine break-make of another crystal head insertion the utility model.Hold part that another part of device of the test netting twine break-make of the utility model promptly contains A netting twine socket to netting twine distributing frame place; The many netting twines that will be positioned at this place one by one crystal head of an end separately insert A netting twine socket; If LED is lighted, the two ends that terminal network line socket that the crystal head system that then can confirm to insert this moment is connected with B netting twine socket is a netting twine.In like manner accomplish the identification of all netting twines.
