Abstract
The invention relates to a method for automatically and uniformly testing TV images and sound, comprising a core PC (Personal Computer) machine as synchronous control. The method is characterized in that the core PC machine provides various image and sound signals for a TV to be tested through a control signal generator; then the PC controls the work of the TV to be tested and the signal generator through the RS-232 communication; and finally the PC machine acquires the image-related information of the TV to be tested through a color analyzer and grabs the sound information of the TV to be tested through an MICPHONE. In the invention, the previous flow of detection in substations is integrated into a uniform automatic test system, the labor cost and the equipment cost are reduced, the production efficiency of a production chain is improved and the human misjudgment is decreased.

Background technology
Present AV test, the COMPONENT test, the HDMI test, the VGA test, picture and sound detection that the TV test is done are carried out operation in the mode of streamline.
The AV testing station is that the machine that assembles is switched to AV source, artificially detect then red, green, blue, grey menu and
Whether left and right acoustic channels is normal, and the instrument of use has signal generator and DVD, and stereo set.
The COMPONENT testing station is that the machine that assembles is switched to COMPONENT source, and whether artificially detect red, green, blue, grey menu and left and right acoustic channels thereof then normal, and the instrument of use has signal generator, and stereo set.
The HDMI testing station is that the machine that assembles is switched to HDMI source, and whether artificially detect red, green, blue, grey menu and left and right acoustic channels thereof then normal, and the instrument of use has signal generator and DVD, and stereo set.
The VGA testing station is that the machine that assembles is switched to VGA source, artificially detects red, green, blue then, whether grey menu is normal, and the instrument of use has signal generator and DVD.
The TV testing station is that the machine that assembles is switched to TV source, and whether artificially detect red, green, blue, grey menu and left and right acoustic channels thereof then normal, and the instrument of use has DVD.
Its testing process as shown in Figure 1, this method of testing has following shortcoming:
1) in the test process, because of the pipelining mode, each erect-position all needs need plug power line and holding wire, and the pat that each erect-position detects belongs to roughly the same, and repetitive operation is lost time;
2) in the whole test process, operator's stand-by period is divided into two parts, thereby causes these times for the treatment of can't carry out other operations, and efficient reduces (waiting for that TV flows to the TV state of predetermined erect-position and wait-for-response);
3) artificial manual mode is adopted in test, and causing the people easily is misoperation and erroneous judgement;
4) owing to need repeatedly the shake of plug wire and collector plate, may cause loose contact, the wire rod consume is serious.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this invention is to provide a kind of TV picture, the sound method of unified test automatically, this method can be well with in the past AV station, the COMPONENT station, HDMI station, VGA station, the picture at TV station and sound detection are incorporated into a station and finish, reduced artificial erroneous judgement, reduced human cost and equipment cost thereof, production efficiency is provided.
The present invention is achieved in that a kind of TV picture, the sound method of unified test automatically, it is characterized in that: the core PC provides various pictures and voice signal for TV to be measured by the control signal generator; PC is by the work of RS-232 Communication Control TV to be measured and signal generator then; Last described PC obtains the relevant information of TV picture to be measured by color analyzer; Grasp the acoustic information of TV to be measured by MIC PHONE.
For achieving the above object, the present invention is achieved in that a kind of TV picture, sound is the system of unified test automatically, the core PC that comprises Synchronization Control, it is characterized in that: described core PC is connected with white balance card and signal generator respectively by serial ports, described white balance card is connected with signal generator and TV to be measured respectively, the output of described signal generator is connected with TV to be measured through signal distributor, and described core PC also is connected with and is used to obtain the brightness of TV picture to be measured and the color analysis instrument and the MIC PHONE that is used to obtain TV acoustic information to be measured of color temperature information.
The present invention adopts PC to come picture and the sound of control detection TV, operator needs only wiring and reads sign indicating number, this system just can finish the action of all pictures and sound detection, and this system has friendly user interface, allow the engineer can be according to the demand of oneself, select corresponding configuration, realization AV stand, the pictures at Component station, HDMI station, VGA station and five stations, TV station and sound detection be incorporated into a station and finish and reduced artificial erroneous judgement, reduced human cost and equipment cost has improved production efficiency.

Embodiment
Below in conjunction with drawings and Examples the present invention is described further.
As shown in Figure 2, core PC of the present invention provides various pictures and voice signal for TV to be measured by the control signal generator; PC issues orders for TV to be measured by the white balance card and obtains the VGA signal of signal generator then; Last described PC obtains the relevant information of TV picture to be measured by color analyzer; Grasp the acoustic information of TV to be measured by MIC PHONE.Because the signal that will detect is more, therefore, the signal that signal generator produces can offer TV to be measured via signal distributor again.We can design concrete hardware system by this method, as shown in Figure 3, the invention provides a kind of TV picture, sound is the system of unified test automatically, the core PC that comprises Synchronization Control, it is characterized in that: described core PC is connected with white balance card and signal generator respectively by serial ports, described white balance card is connected with signal generator and TV to be measured respectively, the output of described signal generator is connected with TV to be measured through signal distributor, and described core PC also is connected with and is used to obtain the brightness of TV picture to be measured and the color analysis instrument and the MIC PHONE that is used to obtain TV acoustic information to be measured of color temperature information.
