Fig. 2 shows the circuit block diagram for the multi-core cable test system that embodiments of the invention 1 provide.As shown in Fig. 2
The multi-core cable test system includes cable input end connection device 100, cable output end connection device 200 and cable tester
300, wherein cable input end connection device 100 is connected with the input 10 of cable to be measured, and the input of cable to be measured is with more
Individual input port；Cable output end connection device 200 is connected with the output end 20 of cable to be measured, the output end tool of cable to be measured
There are multiple output end ports.
The present invention is connected, and use cable output end using cable input end connection device with the input of cable to be measured
Attachment means, it is connected with the output end of cable to be measured, it is only necessary to which connection once, can be by each input port of cable to be measured
It is connected with each output end port with cable tester, it is not necessary to by each input port of cable to be measured and each output end end
Mouth is connected one by one with cable tester, improves the operating efficiency of multi-core cable test.
Cable tester 300 includes：
Transmitting element 310, it is connected with cable input end connection device 100, for inputting end connection device by cable
100, send a test signal to each input port of cable to be measured respectively；
Receiving unit 320, it is connected with cable output end connection device 200, for exporting end connection device by cable
200, receive a test feedback signal from each output end port of cable to be measured respectively；
Comparing unit 330, it is connected with receiving unit 320, for by each test feedback signal of cable to be measured, with work
Each test feedback signal of normal cable is compared；
Judging unit 340, it is connected with comparing unit 330, for judging cable work to be measured according to the result of the comparison
It is whether normal.
The judging unit 340 is and normal for showing each test feedback signal of cable to be measured in the result of the comparison
When each test feedback signal of work cable corresponds to identical, judge that the cable to be measured is working properly.
Specifically, first, cable tester is using normal work cable as test target, respectively to each of normal work cable
Individual input port sends a test signal, and each test signal is by corresponding cable passage, and in cable working properly
Each output end port at export respectively one test feedback signal, so as to obtain each test of cable working properly feedback
Signal.It should be noted that：When it is determined that whether cable is normal work cable, current pin type cable conducting can be used to survey
Method for testing.
Secondly, cable tester inputs end connection device, respectively to be measured using cable to be measured as test target by cable
Each input port of cable sends a test signal, and each test signal is treating survey line by corresponding cable passage
A test feedback signal is exported at each output port of cable respectively, so as to obtain each test feedback letter of cable to be measured
Number.
By taking 12 core cables as an example, its input has 12 input port P1 to P12, and output end has 12 output ends
Port Q1 to Q12.Cable tester accordingly sends test signal S1 to S12 to input port P1 to P12 (i.e. to input
Port P1 sends test signal S1, sends test signal S2 to input port P2, the rest may be inferred), test signal S1 to S12 leads to
Corresponding cable passage is crossed, accordingly output test feedback signal F1 to F12 (is being exported at output end port Q1 to Q12
Output test feedback signal F1 at the Q1 of port is held, the output test feedback signal F2 at the Q2 of output end port, the rest may be inferred).
It should be noted that the test signal that cable tester is sent to each input port of cable can be identical
Or it is different.
Finally, cable tester is by each test feedback signal of cable to be measured, each test with cable working properly
Feedback signal is compared, and in each test feedback signal and each test feedback letter of cable working properly of cable to be measured
When number correspondence is identical, judge that cable to be measured is working properly.
Similarly, by taking 12 core cables as an example, if the test feedback exported at the output end port Q1 to Q12 of cable to be measured
Signal is F1 to F12, the test feedback signal that the output end port Q1 ' of cable working properly is exported to Q12 ' places for F1 ' extremely
F12’.If the output end port Q1 to Q12 of cable to be measured is corresponding in turn to the output end port Q1 ' to Q12 ' in cable working properly
(i.e. output end port Q1 corresponds to output end port Q1 ', and output end port Q2 corresponds to output end port Q2 ', and the rest may be inferred),
Then the test feedback signal F1 to F12 of cable to be measured is corresponding in turn to the test feedback signal F1 ' to F12 ' in cable working properly
(testing feedback signal F1 and correspond to test feedback signal F1 ', test feedback signal F2 corresponds to test feedback signal F2 ', according to
This analogizes).If the test feedback signal F1 to F12 of cable to be measured and cable working properly test feedback signal F1 ' to F12 '
It is corresponding identical (it is identical with test feedback signal F1 ' to test feedback signal F1, test feedback signal F2 is with testing feedback signal
F2 ' is identical, and the rest may be inferred), then judge that the cable to be measured is working properly.
In summary, first, the present invention uses judging unit, treats whether the work of survey line cable is normally carried out judging, rather than
Judge whether cable work to be measured is normal, and basis for estimation is more objective using manual type, improve testing lines work effect
Rate and the degree of accuracy.
Secondly, the present invention uses transmitting element, while sends a survey respectively to each input port of cable to be measured
Trial signal, and receiving unit is used, while the test feedback signal of each output end port output of cable to be measured is obtained, rather than
Test signal is sent to each input port of cable to be measured successively, and obtains each output end port of cable to be measured successively
The test feedback signal of output, further increase the operating efficiency of multi-core cable test.
Finally, the present invention uses comparing unit, and when testing cable to be measured, cable tester is once stored with the work of certain class
Each test feedback signal of normal cable, follow-up similar cable (i.e. core number identical cable to be measured) to be measured can be carried out
Continuity test, it is not necessary to often test a cable to be measured, all set once to cable tester, further increase testing lines
Operating efficiency.
