Fig. 4 then shows the embodiment functional block diagram of wireless signal measurement system of the present invention.
The wireless signal measurement system of legend has the signal source 401 producing signal, as previous embodiment is contained, test signal is produced by control end device, signal inputs to test system 403 by the signal input unit 402 of system, the wireless signal being loaded in specific electromagnetic wave frequency range sent after treatment is exported by test system 403, received by the signal receiving unit 404 in system, and measure wherein signal strength signal intensity, as obtained the wireless signal of reception by signal strength measurement unit 405, such as measure wherein with the signal strength signal intensity that RSSI represents.
According to embodiment, the present invention disclose book disclose embodiment test be divided into two benches, first stage is the balance between test test system and test environment, wherein, signal strength measurement unit 405 measures the signal strength signal intensity of former test signal, the signal strength signal intensity of the wireless signal exported with test system 403 is compared, particularly measure the signal strength signal intensity of same passage (channel), after the signal strength values of the first comparing unit 406 contrastive test signal in figure and wireless signal or its equal data, hardware adjustment 407 can be carried out according to this.
If when there is no balance according to signal, compare as by a thresholding (being set to the first thresholding), i.e. adjustment test macro, hardware adjustment 407 in figure can comprise various signal line, contact, connector and tester table itself, may be all affect the unbalanced reason of signal, such as wherein network line (RJ-45) should use short-term, and use tool trip to fix, these all may affect test result, therefore, after adjustment test macro, return Received signal strength and judge signal-balanced step.
Afterwards, after confirmation signal balance, carry out second stage test again, the object of second stage makes same test system all can have identical or close test result at different tester tables by adjustment, major way implements signal adjustment by signal-conditioning unit (as attenuator) to the signal strength measurement of different platform, result is reached unanimity, it is hereby ensured on different tester tables, have different results to the test result of follow-up test system is unlikely.
As obtained the signal strength signal intensity of the wireless signal that test system 403 exports with the second comparing unit 408, with this comparison sample data 410, sample data 410 as the test result produced by other test macros, and can as the sample of adjustment other system after assessment.If test result and sample data 410 have certain gap, as assessed with certain threshold (being set to the second thresholding), then system is according to the pad value of the test result adjustment signal adjustment unit 409 of the second comparing unit 408, adjusts the wireless signal of test system 403 output with this.
In this example, signal adjustment unit 409 is for being located at each signal processing apparatus and receiving test system 403 and export attenuator on the signal receiving device of wireless signal, the attenuation of systemic presupposition can be provided with, or perform adjustment by control end, the balance between different tester table is obtained by adjustment signal attenuation, comprise forward and compensate (positive compensation) and Contrary compensation (negative compensation), when signal strength signal intensity is too high, Contrary compensation can be imposed; If signal strength signal intensity is too low, then imposes forward and compensate, allow the signal between different platform reach unanimity.
Similarly; wireless signal measurement system disclosed by this example can be tested simultaneously be exported by test system 403 wireless signal being loaded in different frequency range; wireless signal at least comprises the signal carried by 2.4GHz frequency range and the signal carried by 5GHz frequency range; by system with the signal of each frequency range of identical or different host computer system processes, remake out the assessment of hardware adjustment or pad value compensation.
Flow chart shown in Fig. 5 then then describes the embodiment flow process of wireless signal measurement system method for building up.
Step at the beginning, as step S501, system is matching measurement value (signal as exported by test system) and source signal value (as test signal) through measure signal intensity, do you judge that signal strength signal intensity balances by comparison? (step S503), thresholding can be introduced especially as criterion, if judge and uneven (no), obviously have the interference that hardware or test environment cause, therefore hardware adjustment can be performed, as step S505.System through adjustment gets back to step S501 by continuing, repeatedly matching measurement value and source signal value, as the basis of hardware adjustment.
After hardware adjustment completes, step continues as S507, does by by comparison specific sample signal, system judge that whether the signal strength signal intensity measured by each tester table consistent? if variant, and difference needs adjustment through judging excessive, i.e. step S509, allow the test result between different test environment reach unanimity by adjustment pad value, just can obtain correct and in consistent substandard test result.Adjusted (step S509), to set up another test macro, as step S511 by above-mentioned hardware adjustment (step S505) and pad value.
Fig. 6 shows the embodiment flow chart two of wireless signal measurement system method for building up of the present invention.
In this embodiment flow process, step retouches some details of book more accurately, on the whole, step has two test phases at least, one is for find the issuable interference of hardware by signal difference, step is as started as described in S601, be received from the wireless signal that test system (61) exports, for another example step S603, measure the signal strength signal intensity receiving the wireless signal that test system since then exports, comprise the signal strength signal intensity measured and input to the original test signal of test system, the intensity of original test signal can be provided by control end.Then perform as contained in step S605, comparison signal source (62) the test signal intensity that exports and measure the signal strength signal intensity that test system exports.
In the step compared, can introduce the first thresholding as the standard judged, as step S607, whether the first thresholding has because hardware device produces too much loss in order to judge the signal strength signal intensity of the wireless signal that test system exports.Represent when the signal intensity difference of test signal and wireless signal is greater than this first thresholding and be not inconsistent standard (no), can judge to answer according to table look-up (step S609) position of adjustment, as step S611, the hardware device of adjustment wireless signal measurement system, step still gets back to S601 afterwards, through the hardware device of adjustment wireless signal measurement system repeatedly, the problem that hardware device itself causes signal disturbed can be exempted.
For example, preliminary test result can be obtained at the testing procedure in this stage, test system and control end is judged whether at different frequency range (as 5GHz with this, the signal strength signal intensity (RSSI) of 2.4GHz) testing is balance, the signal strength signal intensity (as 45≤RSSI≤55) in particular range of such as test system and control end, and difference, within a specific dB value (as 5dB), namely can be considered balance each other.
If judge, the signal strength signal intensity of test system and control end is as uneven, and namely both differences are more than the threshold value of a setting, now will carry out the inspection of test environment, comprises the performance number setting of the communicating circuit detected in test system; The connector on antenna circuit board should be distinguished, avoid circuit trace through the printed antenna position of antenna plate, generation can not be disturbed, as cross-talk (cross talk) to avoid exception; Confirm to avoid the circuit on antenna circuit and antenna itself to be wound around; Whether detect the cable connector of antenna to be firmly connected with the circuit board of test system, such as confirm antenna, the joint of attenuator and relevant cable has bolt tight; If detect too low from the signal strength signal intensity of control end, then pad value should be reduced; Detect cable whether to be suitably connected with attenuator, avoid cable losses (cable loss) to cause the difference of different tester table.Other correction projects also can have the suction ripple material confirming bottom shielding box whether to have damage, confirm jig plate be placed in put on shielding box summit position, confirm that whether the interval of test system and antenna jig plate suitable etc.
Afterwards, the signal strength signal intensity produced after hardware adjustment will with another sample data (63) comparison, step enters S613.The normal data of Gong the comparison that sample data (63) provides for system, can be the test result that same test system produces in another wireless signal measurement system, in order to judge whether this test system has different test results in different wireless signal measurement systems.
Afterwards as step S615, whether both judgements data are consistent, now can introduce another second thresholding, second thresholding is in order to judge whether this test system has different test results in different wireless signal measurement systems, (if difference is less than the second thresholding), obviously completion system corrects, and can set up a new test macro, as step S623.
If not, represent the signal value of current systematic survey and sample data (63) inconsistent, difference is greater than the second thresholding, now system carry out as step S617 adjust attenuator carry out signal compensation.At this test phase, for asking data consistent, forward will be performed by adjustment pad value and compensating or Contrary compensation.
After signal compensation, step continues to perform as described in step S619, and system is received from the wireless signal that test system exports again, then measure signal intensity, as step S621.Through repeatedly testing and adjustment pad value, until after meeting demand, by setting up a new wireless signal measurement system, as step S623.
