Sub- end tester has MSP430 main control chip and wireless radio-frequency communication module；First patchcord, the second patchcord, third turn
In wiring, the 4th patchcord, each patchcord can use 20 core of core.
The host computer and the main side tester are wirelessly connected by network signal；Two are stayed outside the main side tester
Connector interface, two connector interfaces pass through the first patchcord respectively and are merged together with the second patchcord, and with to survey line
Whole cores of cable main side are connected；The part core of the other end of the cable to be measured passes through described in third patchcord connection
First sub- end tester, another part core connect the second sub- end tester by the 4th patchcord；Described first
Sub- end tester and the second sub- end tester and the main side tester are wirelessly connected by radiofrequency signal.The host computer
It is wirelessly connected by the way that the corresponding IP address of the main side tester and port numbers and the main side tester are arranged.The host computer
For inputting the wiring relationship of cable main side to be measured core and sub- end line core by scheduled format and saving.The first sub- end is surveyed
The I/O mouth of examination instrument and the second sub- end tester is circumscribed with pull-up resistor.
As shown in figure 3, the testing process of above system are as follows:
Step 1, the wiring relationship that the host computer is stored by wireless network card is sent to the main side tester；It
Afterwards, the main side tester is set to high level for all I/O mouthfuls；
Step 2, the main side tester reads in first wiring relationship, and the I/O mouth that corresponding core is connected is reduced to
Low level；
Step 3, the main side tester by the wiring relationship currently read in while being sent to institute by wireless radio frequency modules
State the first sub- end tester and the second sub- end tester；
Step 4, the described first sub- end tester and the second sub- end tester are closed according to the wiring currently read in
System, setting should be low level except this core, remaining core should be the decision rule of high level；
Step 5, the described first sub- end tester and the second sub- end tester are successively read the I/O mouth that core is connected
Level, and be compared with the decision rule in step 4, when the level result of reading and decision rule difference, then determine institute
Stating the wiring relationship currently read in, to correspond to core connection wrong or have a misconnection phenomenon；If read all level results with judgement
Rule is identical, then determines that the correspondence core connection of the wiring relationship detection currently read in is errorless and existing without corresponding misconnection
As；
Step 6, after the described first sub- end tester or the second sub- end tester, which have, determines result, by wirelessly penetrating
Frequency module is sent to the main side tester；
Step 7, the main side tester will determine result by being sent to the host computer；
Step 8, next wiring relationship is read, and the I/O mouth that corresponding core is connected is reduced to low level, repeats step
3-7；
Step 9, step 8 is repeated, until whole wiring relation tests are completed；
Further include: all determine as the result is shown in the host computer, and saves.
The step 5 specifically: the first sub- end tester is related to corresponding to its connection according to first wiring
The sequence of the last item wiring relationship reads the I/O mouth level that every core is connected respectively, and with the decision rule in step 4
It is compared, when the level result of reading and decision rule difference, then determines that the wiring relationship currently read in corresponds to line
Core connection is wrong or has misconnection phenomenon, stops detection；If all level results read are identical as decision rule, the is notified
Two sub- end testers are started to work；The second sub- end tester connects first corresponding wiring relationship to the end according to it
The sequence of one wiring relationship reads the I/O mouth level that every core is connected respectively, and carries out with the decision rule in step 4
Compare, when the level result of reading and decision rule difference, then determines that the wiring relationship currently read in corresponds to core company
It is connected to accidentally or is had misconnection phenomenon, stops detection；If all level results read are identical as decision rule, work as described in judgement
The correspondence core connection of the wiring relationship detection of preceding reading is errorless and without corresponding misconnection phenomenon.
In one embodiment of the method for the present invention, host computer runs software, the format input in host computer as needed
Corresponding wiring relationship simultaneously saves, as shown in Figure 4；As shown in figure 5, it is corresponding to fix main side tester in upper computer software
IP address and port numbers realize shaking hands between wireless main side tester and host computer, at this time main side tester can with it is upper
Position machine is communicated by WIFI；Wiring relationship is sent to main side tester by wireless network card by host computer；
Main side tester is by all I/O mouthfuls most high level；Main side tester reads in first wiring relationship, and will be corresponding
Connect I/O mouthfuls of core most low level；Main side tester notifies the first sub- end tester and the second son by wireless radio frequency modules
End tester is detected to connect I/O mouthfuls of the wiring state of core is corresponded in first wiring relationship；First sub- end tester
After receiving corresponding data with the second sub- end tester, decision rule is determined and by corresponding sequence requirement to corresponding I/O mouthfuls of level
It is read out that (the first sub- end tester terminates after level is read to notify that the second sub- end tester carries out by wireless radio frequency modules electric
Flat read work).As shown in Fig. 2, since each I/O mouthfuls there are 1K pull-up resistor, so corresponding pin only passes through receiving the end A
The result read in when the low level that cable core is sent just be it is low, receive high level or do not receive the level of main side tester A
When, the I/O mouth level result of the reading of the first sub- end tester or the second sub- end tester is height, and setting removes this bar line accordingly
Core, which should be remaining outer core of low level, should be the decision rule of high level.
In each judgement, if the level result that the first sub- end tester or the second sub- end tester are read is sentenced with described
It establishes rules then inconsistent, then stops detecting, and the sub- end tester of inconsistent first or the second sub- end occur by discovery level result
Tester will test result and be sent to main side tester, and test result is sent to upper by main side tester by wireless WIFI again
Machine；
If the level result and the decision rule that the first sub- end tester and the second sub- end tester are read are consistent,
Then stop detecting, and result will test by the second sub- end tester and be sent to main side tester, main side tester again ties test
Fruit is sent to host computer by wireless WIFI；Next wiring relationship is read, above-mentioned steps are retransmitted；Whole cores are repeated up to survey
Examination is completed.
At this point, whole test results are shown in host computer, and saved, if test is the correct core of connection,
Host computer shows result as shown in figure 5, if test is the core of connection error, and host computer shows that result is as shown in Figure 6.
Through the above technical solution and embodiment, the test macro and method provided by the invention based on wireless transmission can
It is widely used in the quality test field of cable on-off and misconnection, realizes the detection to associated cable wiring state.
