Description
Technical field
The utility model relates to a kind of pick-up unit, and is particularly a kind of based on the device of wireless transceiving modes to the polycore cable quality testing.
Background technology
In the electronic equipment, the equipment powerful, that control is accurate, reliable is formed by connecting through intensive cable, network by increasing electronics extension set, parts in modern times.Correctness and reliability that cable, network connect have play a part important in ensureing whole electronic system reliability service.To the automatic test and the check of indexs such as the conducting of complicated cable, network, insulation, be an indispensable link in cable assembling, the production run.Manual, the semi-automatic test of traditional low pressure, low current can not satisfy the needs that modern highly reliable electronic equipment is produced far away.
At present the cable detection of electronic equipment all adopts manual inspection mode traditional, that fall behind, with avometer, hummer and make simple test board detection break-make by oneself; There are following many defectives in the manual inspection method:
1, a people or two people cooperate pointwise to detect, and efficient is low, speed is slow, workload is big, loaded down with trivial details, fatiguability, need contrast drawing, connection table, core wire size, very easily cause omission, false retrieval;
2, can only detection path, can not in tens of core cables, detect short circuit (be misconnection, connect more);
3, generally only detect break-make, do not detect conducting resistance, can not find loose contact, insecure contact.
Thus, the traditional cable detection method can not satisfy the requirement of in enormous quantities, high precision, high reliability cable detection far away.This is that the insider expects the problem that solves.
Summary of the invention
The purpose of the utility model is exactly in order to overcome the deficiency of above-mentioned prior art, and provide a kind of reasonable in design, simple in structure based on the device of wireless transceiving modes to the polycore cable quality testing.
In order to achieve the above object, the technical scheme of the utility model employing is:
A kind of based on the device of wireless transceiving modes to the polycore cable quality testing, be connected to form an integral body by main frame and slave through tested polycore cable, wherein:

Based on tested polycore cable radical in the utility model is the arbitrary integer greater than 2.So selecting main frame cable interface 2 and slave cable interface 6 is same model.Promptly the port of two interfaces also equates.
Suppose that tested polycore cable radical and two interface port numbers are N.
It concerns that square formation all can be expressed as so:
A=(a
ij)
n×n
=
If demonstrate on the display screen U4:
This square formation is used for the corresponding relation of interface port, and upper triangular matrix is effective, comprises diagonal line; Its physical significance is that O is not for connecing; 1 for connecting; X is invalid.
If the square formation that demonstrates on the display screen U4 is:
This square formation is used for the corresponding relation of tested polycore cable, and upper triangular matrix is effective, but does not comprise diagonal line; Its physical significance is that O is invalid; If X=3, expression two wiring short circuit, if cable is up-to-standard, inserts effectively X=4, and expression detects failure, or radio communication makes mistakes, or the cable quality problems, and it is invalid to insert, and proceeds to scan upper triangular matrix.
The distinguishing feature and the beneficial effect of the utility model are following:
(1) has automatic, fast detecting cable make-break capacity, can make the complicated cable of tens of cores in one minute, accomplish the break-make detection;
(2) have automatic arranged in groups combination short-circuit test, detect short circuit mistake (be misconnection, the connect more) ability that might exist;
(3) programmed control automatic testing process, the repeated detection cable is convenient to quality management at any time, increases work efficiency greatly;
