Description
Technical field
The present invention relates to a kind of pick-up unit, 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 object of the invention 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 present invention's 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:
Said main frame is made up of host shell 1, main frame cable interface 2, master machine antenna 3, communication serial port 4, keyboard 5 and main frame built-in circuit module 9 again;
Said slave is again by constituting from engine housing 8, slave cable interface 6, slave antenna 7 and slave built-in circuit module 10;
Said main frame built-in circuit module 9 includes host CPU microprocessor U1, main frame transceiver module U2, main frame measurement module U3 and display screen U4, totally 4 parts;
Said slave built-in circuit module 10 includes slave CPU microprocessor U5, slave transceiver module U6 and slave switch matrix chip U7, totally 3 parts.
Host CPU microprocessor U1 adopts ARM embedded microprocessor chip among the present invention, and chip integration has become lcd controller, the synchronous/asynchronous serial ports, and dma controller, vectorial interruptable controller, and with device in the sheets such as MII and MDIO interface and JTAG debugging interface; Launch on-chip timer simultaneously and offer the operating system use, frequency of operation is 76.205MHZ altogether.And slave CPU microprocessor U5 is a general-purpose microprocessor chips.During work, main frame and slave are by communication protocol and the realization of both sides' radio frequency receiving and transmitting front end through agreement of separately microprocessor.Be the simulating signal that the built-in signal generator circuit of main frame produces a CF, and send into corresponding passage through measurement module; The switch matrix chip of slave is selected the corresponding passage of accepting under the control of self processor, and sends into sendaisle after the signal amplitude of carrying out handled and pass main frame back; Main frame is sent into built-in wave detector after selecting corresponding passage to receive, and reads the amplitude information of passing signal back; After built-in ADC sampling, send into processor and carry out data processing.After accomplishing each lane testing successively, host-processor can be analyzed and handle the gained data, and feeds back to the user to the result through display screen interface, accomplishes polycore cable quality testing task.
Whole design idea of the present invention is: adopt microprocessor center control function on the one hand, carry out above-mentioned modular construction design, the many technical indicators of reasonable distribution each several part are set up hardware platform.Utilizing the microprocessor operation system on the other hand, is the interface with main frame cable interface 2 with slave cable interface 6, and clear and definite interface standard is set up two ends interface relationship square formation, and works out it and detect software package.When implement detecting, read the value that concerns that square formation is any through display screen U4, but just effective and rapid is judged the quality condition of tested cable.
Based on tested polycore cable radical among the present invention 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.
Distinguishing feature of the present invention and beneficial effect 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;
(4) novel, easy to use.Voice suggestion is arranged, and man-machine interface is friendly, super low-power consumption and low capacity prompt;
(5) communicate by letter conveniently with PC, can make things convenient for the download cable type spectrum, have unknown type spectrum autolearn feature simultaneously;
(6) main frame can store type spectrum and 1536 cable measurement results of 512 kinds of cables.And can memory contents be sent to the PC management system;
(7) adopt embedded real-time operating system, demonstrations of Chinesizing fully of AD-TFT colorful display screen, the man-machine interface close friend, easy to operate;
(8) master/slave machine formula structure, be particularly suitable for original position wireline test in the car;
(9) master/slave machine radio communication need not wiring;
(10) can test together many whiles, do not disturb mutually.
