Description

The method of automatic detection computations machine CD voice playing function

Technical field: the present invention relates to the whether normally automatic detection range of computing machine of CD voice playing function.Background technology: at present, in the computing machine production run, need test to CD voice playing function.The contingent subject matter of CD voice playing has following a few class: 1, the disk reading capacity of CD drive has problem, does not recognize to coil or do not read to coil and cause CD can't play phenomenon; 2, sound card has problem, and it is unusual to cause CD to play; 3, the tone frequency channel wire that connects CD drive and sound card does not connect or partly even all open circuit, causes the analog form play CD unusual; 4, use CD to play instrument, when a first song jumps to another first song and plays, cause computer corruption; 5, system performance has problem or noise excessive, causes that CD plays distortion.

Present test mode is a play CD, and simultaneously by artificial audition, whether artificial judgment can be play then, whether left and right acoustic channels is all normal etc.

This kind test mode causes following puzzlement to manufacturer: 1, every machine all needs artificial listening, and needs a large amount of manpowers, has increased human cost and has caused the production capacity bottleneck; 2, can't guarantee test mass, may or be difficult for owing to environmental interference judging causing human negligence to make problematic machine by quality inspection; 3, the machine of pinpointing the problems can't be judged immediately and need expend the defect of which part software or hardware the plenty of time and determine the position of makeing mistakes.

Also there is not at present good solution in the industry, so press for a kind of Validity Test method that can overcome above defective.

Summary of the invention: the present invention seeks to solve the functional test of computing machine CD voice playing and need expend a large amount of manpowers, and cause the production capacity bottleneck, can't guarantee the problem of test mass.

The inventive method is finished according to the following steps:

The first, the CD sample generates---and on CD voice playing and the normal computing machine of sound-recording function, play CD, and recording are made into the master sample file;

The second, CD voice playing---on CD to be detected, finish the playing function of CD audio frequency;

Three, synchronization---the collection of finishing sound in the CD voice playing is recorded;

Four, interpretation of result is relatively---and the result to recording analyzes, and compares with the master sample file, judges whether data recording and master sample file be identical, and difference represents that this machine CD voice playing is undesired, then changes fault processing;

Five, finishing playing---data recording and master sample file are identical, play normally, and detection is passed through, and then changes end process.

Advantage of the present invention and effect: 1, the present invention is by the monitoring of anthropomorphic dummy to the CD voice playing, reaches automatic test purpose.By the method for synchronization, obtain the effect that CD plays, thereby simulated the sense of hearing of people's ear.Recording file of recording and the normative document that generates on normal machines are in advance compared, so just can judge whether the sound that plays out is normal, thereby simulate the deterministic process of human brain, realized the robotization of voice playing test; 2, liberate the employee who is used for manual detection in a large number, reduced human cost, and solved the problem that manual detection causes the production capacity bottleneck; 3, detection method can guarantee test mass automatically, can detect the various trickle defective that occurs in the playing process, and having solved effectively may be because of the problem of human negligence omission.

Embodiment:

Embodiment 1

As shown in Figure 1, this automatic testing method is finished according to the following steps:

Five, finishing playing---data recording and master sample file are identical, play normally, and detection is passed through, and then changes end process.Wherein, the CD sample generates and finishes by following steps:

The first, select the normal computing machine of playing function---select all normal computing machine of CD voice playing and sound-recording function, be used for the production standard sample, use during for test;

The second, select CD medium section---to making the CD file part that sample uses, selection track number and broadcast begin, end position is the time;

Three, play selected CD medium section;

Four, synchronization---when CD plays, record, obtain the CD voice data;

Five, the recording result is preserved into the testing standard file.

Concrete test process is seen Fig. 3 test flow chart, and process flow diagram specifies as follows:

1, computer system to be measured is prepared, and inserts the CD laser disc identical with the making sample and test macro is written in CD drive;

2, check whether the CD-ROM state is normal, if undesired, forwards fault processing to;

3, check whether the CD in the CD drive is normal, if undesired, forwards fault processing to;

4, initialization sound pick-up outfit checks whether the playback of sound card and recording partial status be normal.If undesired, forward fault processing to;

5, the broadcast CD audio frequency media part identical with sample;

6, adopt in the record mode to the CD audio frequency media of the playing recording of sampling;

7, check whether the CD part that will detect finishes.If finish, then forward the interpretation of result processing section to; Otherwise continue to play and recording;

8, recording result and sample comparison: analyze the data of recording sampling, and with the contrast of testing standard sample file, judge whether the sound of CD broadcast normal.If undesired, then forward fault processing to

9, test is passed through: report test result, end of test (EOT);

10, fault processing: according to type of error, judge, the error differentiating reason, undesired as the CD drive state, forget and place CD or CD has problem, the sound card state is undesired, tone frequency channel wire does not connect, the tone frequency channel wire L channel partly opens circuit, the tone frequency channel wire R channel partly opens circuit, the audio distortions play etc., report this mistake, end of test (EOT).

Playing automatic testing software (CDTest) with computing machine CD below is that example is specifically described:

CDTest is by the monitoring of anthropomorphic dummy to the CD voice playing, reaches automatic test purpose.By the method for synchronization, obtain the effect that CD plays, thereby simulated the sense of hearing of people's ear.Recording file of recording and the normative document that generates on normal machines are in advance compared, so just can judge whether the sound that plays out is normal, thereby simulate the deterministic process of human brain.

Before the test, the production standard sample file.On a CD playing function and all normal machine of sound-recording function, insert a CD laser disc.Open the CD test procedure, choose the track part that to survey, the production standard sample file.

On to-be-detected machine, identical CD dish, insert in the CD drive after, just can open the CD test procedure, begin to have tested.

At first, whether the state of program detection CD-ROM, CD and sound card is normal.Then, Automatic Program play CD and recording.Features such as the amplitude that acquisition plays sound, energy, peak value, with the master sample file relatively and draw test result.

The CD test procedure can be selected numeral or analog form play CD.When selecting the analog form play CD, can also detect tone frequency channel wire does not have to insert situation good or that open circuit.

Like this, by the test of CD test procedure record (log) file is analyzed or further checking, can the orientation problem position, FAQs is as follows:

1) disk reading capacity of disk drive has problem, does not recognize to coil or do not read to coil and cause CD can't play phenomenon;

2) sound card has problem, and it is unusual to cause CD to play;

3) tone frequency channel wire that connects CD drive and sound card does not connect or partly even all open circuit, causes the analog form play CD unusual;

4) use CD to play instrument, when a first song jumps to another first song and plays, the problem of computer corruption;

5) system performance has problem or noise excessive, causes that CD plays distortion.

Therefore, by this method, effectively whether detection computations machine CD voice playing function is normal.
