The utility model is achieved in that
The FQC automatic checking device of a kind of projector production run, it is characterized in that: it comprises the automatic test-based examination PC of a FQC, HDMI signal generator, audio signal generator, alternating current steady voltage plug, the automatic test-based examination PC of described FQC, HDMI signal generator, audio signal generator all are connected with described projector; Described alternating current steady voltage plug directly is connected with described projector, the automatic test-based examination PC of FQC respectively.
Further, it also comprises digital signal generator, and described digital signal generator is connected between described projector and the automatic test-based examination PC of FQC.
Further, it also comprises the consumption power test instrument that is used to connect described projector, described consumption power test instrument and alternating current steady voltage plug switch tool by a power supply and are connected to described projector, and the automatic test-based examination PC of described FQC is connected to described consumption power test instrument.
Further, the automatic test-based examination PC of described FQC also is connected to described projector by 32 bit parallel I/O ports and DDC data buffer.
Further, described projector inside is provided with the air velocity transducer that is subjected to the automatic test-based examination PC control of FQC.
Advantage of the present utility model is:
The utility model carries out robotization by the automatic test-based examination PC of FQC to projector and detects, and has simplified inspection work, has reduced the time of checking, reduce the test-based examination personnel, improve detection efficiency, avoided supervisory personnel's omission, flase drop, can also realize the automatic storage of test data.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the structured flowchart of the utility model one embodiment.
[embodiment]
See also shown in Figure 1ly, embodiment of the present utility model is described in detail.
As shown in Figure 1, an embodiment of the present utility model is used for the detection of liquid crystal projector 1, and it comprises: a HDMI (HDMI (High Definition Multimedia Interface)) signal generator 2, a power supply switch tool 3, an alternating current steady voltage plug 4, a consumption power test instrument 5, a digital signal generator 6, an audio signal generator 7, the automatic test-based examination PC8 of a FQC, one 32 bit parallel I/O ports 9 and DDC (Direct Digital control) data buffer 10.Described HDMI signal generator 2, power supply switching tool 3, digital signal generator 6, audio signal generator 7 all are directly connected to described liquid crystal projector 1, described power supply switches tool 3 and is connected respectively to described alternating current steady voltage plug 4, consumption power test instrument 5, the automatic test-based examination PC8 of described FQC is connected to described alternating current steady voltage plug 4, consumption power test instrument 5, digital signal generator 6, liquid crystal projector 1 by Serial Control line 11, and is connected to described liquid crystal projector 1 by the PCI slot through described 32 bit parallel I/O ports 9 and DDC data buffer 10.Described liquid crystal projector 1 inside is provided with air velocity transducer (not shown), and described air velocity transducer is used for the wind speed of detection optical engine.
The automatic test-based examination PC8 of described FQC (hereinafter to be referred as PC8) can read the production management number that is stored in liquid crystal projector 1 inside, so that discern the type of being produced automatically, call different testing softwares according to type, carry out the inspection step of corresponding requirements and different Default Values.The utility model device is preset to the saving pattern in the time of can be as required with projector's 1 standby, and its power consumption is tested, and judges according to test value whether it meets design standards, and test value is recorded in the corresponding file of PC8.Described PC8 reads the DDC data of RGB port and HDMI port simultaneously by 32 bit parallel I/O port 9 and DDC data buffers 10, compares with this type DDC data that are pre-stored in PC8 inside, judges whether it is consistent.Described PC8 can carry out consumption power and the test of consuming electric current under the open state by 5 pairs of projectors of consumption power test instrument 1, judges according to test value whether it meets the demands, and test value is recorded in the corresponding file of PC8.Different signal pattern and the signal format of described PC8 control figure signal generator 6 outputs, for example: VGA85HZ1024*768 grid signal is used for inspection and converges, 30% white signal is used to check look inequality and dust, and RGB E signal is used for checking focusing that the OP2 picture is used to check image quality.Described liquid crystal projector 1 inside is provided with air velocity transducer, described air velocity transducer is used for the wind speed of detection optical engine, guarantee the radiating effect of optics, in process of production, through wearing out after a while, need described PC8 transmitting control commands test air speed value, judge that it is whether in certain design specification scope to air velocity transducer.Because projector 1 has video Video terminal, component Y/pb/pr terminal, S signal terminal, RGB terminal, HDMI terminal etc., need be when checking image quality to the different signal of each terminal input, described PC8 sends order by serial ports and carries out the switching of each terminal signals, and whether the Visual Confirmation picture is unusual.Every state when each liquid crystal projector 1 with a kind of type is dispatched from the factory is consistent as volume, luminance contrast etc., and need dispatch from the factory before it dispatches from the factory resets, and described PC8 just can realize this function by sending specified command.This device can be saved in the PC8 automatically to every test data, is convenient to data are extracted, analyze, compared.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
