Description of drawings
Fig. 1 is the composition structural representation of current drain test macro embodiment of the present invention.
Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
For solving the problem that exists in the existing current drain test mode, a kind of brand-new current drain testing scheme is proposed among the present invention.With equipment to be tested with after testing tool is connected, when needs carry out the test of long-term test event, according to prior art in identical processing mode, in connecting line, seal in a resistance, utilize data collecting card to read ohmically magnitude of voltage, and the magnitude of voltage that reads is imported test computer carry out data-switching and demonstration, that is: data collecting card is with the data importing test computer that reads, the LabVIEW program of test computer by editting in advance, pass through data-switching, on the display panel of LabVIEW program, show the current drain situation of equipment to be tested in whole test process, comprise the average current of consumption, performance parameter such as maximum current and minimum current.Different with existing current drain test mode is, in the scheme of the present invention, if the tester wishes to recognize in real time different pairing performance parameters constantly in the test process, so, can on described resistance, connect a digital multimeter (two test pencils of digital multimeter are joined with the resistance two ends respectively), obtain different corresponding constantly performance parameters in the test process in real time by reading this digital multimeter.Like this, the tester need not to interrupt original test procedure, can obtain required performance parameter information at any time, thereby helps the tester in time promptly to find the problem that may exist in the test process, has improved testing efficiency.
Generally, above-mentioned equipment to be tested is that mobile phone is (certain, also can be other equipment that need carry out the current drain test, such as mp3, mp4 etc.), testing tool is CMU200, the digital multimeter that is adopted is Agilent (Agilent) 34411A digital multimeter, and the characteristics of this digital multimeter are can show in real time from test to begin to the current time information such as average current, maximum current and minimum current that equipment to be tested consumed in this time period.Certainly, if adopt other equipment can finish the function of above-mentioned Agilent 34411A digital multimeter equally, also be fine.
In addition, practice is found, for existing current drain test mode, when it is applied to long test event of duration, during such as the test of audio-frequency current and standby current, this test mode has higher degree of accuracy, but, when it is applied to relatively short test event of some duration, during such as the test of start search average current (duration is about 3～4 seconds), degree of accuracy then can reduce greatly, in some cases in addition may basic just test less than the consumed current value.At this problem, provided settling mode among the present invention equally: when needs carry out the duration during the test of short test event, at equipment to be tested, as connecting an oscillograph (oscillograph links to each other with the anode connecting line of mobile phone to be tested by current probe) on the mobile phone to be tested, utilize the characteristic of this oscillograph itself, intercept and capture the current drain image of mobile phone to be tested in whole test process by current probe, to show the performance parameter of mobile phone to be tested in whole test process on the current drain image of these intercepting and capturing, i.e. average current of Xiao Haoing, maximum current and minimum current etc.
Based on above-mentioned introduction, Fig. 1 is the composition structural representation of current drain test macro embodiment of the present invention.As shown in Figure 1, this system comprises:
In addition, this system further comprises: digital multimeter 16, link to each other with resistance 13, and be used for showing in real time the different pairing performance parameters constantly of test process;
Oscillograph 17, link to each other with equipment 11 to be tested, be used for when carrying out the duration during the test of short test event, intercept and capture the current drain image of equipment 11 to be tested in whole test process, show the performance parameter of equipment 11 to be tested in whole test process on this current drain image.
Generally, equipment 11 to be tested is mobile phone; Testing tool 12 is CMU200; Digital multimeter 16 is an Agilent 34411A digital multimeter.
Relevant introduction before the concrete workflow of this system please refer to repeats no more herein.
As seen, adopt technical scheme of the present invention, no matter which kind of duty equipment to be tested is in, all can finish the current drain test job preferably: when needs carry out the test of long-term test event, according to existing mode, after equipment to be tested and testing tool connected, come reading of data by data collecting card, and, in test computer, show the current drain situation of equipment to be tested by the LabVIEW program with the data importing test computer that reads.In addition, can also come different pairing performance parameters constantly in the real-time read test process by the Agilent34411A digital multimeter, thereby in time understand the progress of test, need not to stop test procedure, improve testing efficiency as prior art.Have again, for relatively shorter test event of duration, can intercept and capture equipment to be tested at the current drain image of this section in the short period by oscillographic current probe, and then know equipment to be tested current drain situation during this period of time, thereby solved the not high problem of testing precision of the test event of relatively lacking for this duration in the prior art.In a word, the invention provides a kind of current drain testing scheme that is applicable under the various duties, no matter the duration is long still than short test event, all can guarantee its degree of accuracy, and need not stop test procedure and also can obtain performance parameter in the test process at any time, strive for a large amount of time for the tester pinpoints the problems, improved testing efficiency.
In sum, more than be preferred embodiment of the present invention only, be not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
