For making object of the present invention, content and advantage clearer, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
As stated in the Background Art, in current instrument system, the low instrument of utilance is subject to the restriction of the instrument that utilance is high, can not access more test subsystems, causes the instrument wasting of resources.In order to overcome such defect, solution principle of the present invention is: instrument system is divided into a plurality of instrument subsystems, test subsystems connects equipment under test, test subsystems is according to the testing requirement of equipment under test, determine required target detection instrument, finally from a plurality of instrument subsystems, determine the target instrument subsystem that comprises target detection instrument.Utilize present principles, test subsystems can be called flexibly in other instrument subsystems and test required test instrumentation, and invoked test instrumentation is not subject to the impact of other test instrumentation utilances.
Refer to Fig. 1, the schematic flow sheet of a kind of method of testing proposing for the embodiment of the present invention, the method is applied to the test macro that comprises at least one instrument subsystem and at least one test subsystems, test subsystems connects controls described instrument subsystem, and described instrument subsystem comprises at least one test instrumentation.In this test macro, a test subsystems connects at least one instrument subsystem, each test subsystems is all connected with public network to realize testing to be shared, in each instrument subsystem, the instrument of any two kinds of models is all the configuration mode of N:M, for example: signal source equipment and signal analyzer be appearance in pairs, and its configuration mode is N:M.In order to explain easily the present embodiment, a test subsystems is connected with an instrument subsystem, test subsystems is after in searching connected instrument subsystem, find still to lack certain test instrumentation (being target detection instrument), need go another instrument subsystem (being target instrument subsystem) to temporarily transfer.
In the present embodiment, described method of testing is carried out in test subsystems, and test subsystems comprises the memory cell that stores call relation, and described call relation comprises the locating information that this test subsystems can invoked test instrumentation.Concrete, locating information comprises the type of test instrumentation, the instrument subsystem IP at this test instrumentation place etc.
This method originates in step S101, and test subsystems, according to the testing requirement of equipment under test, is found to lack certain test instrumentation (being target detection instrument), need go another instrument subsystem (being target instrument subsystem) to temporarily transfer target detection instrument.Test subsystems, according to call relation default in memory cell, is searched idle test instrumentation in default call relation list, and then from the test instrumentation of described free time, chooses described target detection instrument.In the present embodiment, say certain test instrumentation " free time " not the utilance of this test instrumentation be 0, and refer to that the utilance of this test instrumentation does not reach at full capacity, can also be continued to utilize.For the present embodiment of explaining better said " free time ", illustrate below: in test subsystems A, signal source equipment utilance is 25%, signal analyzer utilance is 50%, now the utilance of signal source equipment and signal analyzer does not all reach 100%, be " free time ", expression can be utilized by other test subsystems.After calling by test subsystems B, the utilance of signal analyzer is 100%, now signal analyzer at full capacity, can not be called, and the utilance of signal source equipment is 50%, still can be called by other test subsystems.
At step S102, test subsystems, according to target detection instrument, is determined the target instrument subsystem that comprises described target detection instrument.After definite target instrument subsystem, test subsystems sends handover request to described target instrument subsystem, make described target instrument subsystem arrive described target detection instrument according to described handover request, thereby make test subsystems to carry out follow-up test by invocation target test instrumentation.Concrete, the present embodiment also comprises the Virtual Service subsystem being connected with test subsystems, test subsystems sends handover request by Virtual Service subsystem to target instrument subsystem.
