Abstract
本发明的带有电压合成电子调谐系统的彩色电 视机是在电视机中使用黑白电子芯片调谐器和黑白 Monomax子系统集成块，从而提供毋需调试的调谐 器以及可以兼用于UHF(特高频)和VHF(甚高频) 接收的单一调谐器，该调频器具有比较价廉，重量轻 而且毋需在生产线上调试等优点。
The color TV set with the voltage synthesis electronic tuning system of the present invention uses a black and white electronic chip tuner and a black and white Monomax subsystem integrated block in the TV set, thereby providing a tuner that does not need to be debugged and can also be used for UHF (Ultra High Frequency) ) and VHF (very high frequency) receiving a single tuner, the tuner has the advantages of relatively cheap, light weight and no need to debug on the production line.
Description
Technology category under the present invention is the tuning system in the color television set, particularly in color television set, use black and white electronic chip tuner and black and white Monomax subsystem integrated package, thereby the tuner that need not debug be provided and can be used for the UHF(superfrequency) and VHF(very high frequency(VHF)) the single tuner of reception.
Commercially available color television set needs the debugging of video intermediate frequency and audio frequency intermediate frequency when assembling, this just requires complicated commissioning device, and need manually adjust the marking signal of image and sound on production line, and causes the loss of production time and cost.Have again, in debug process, also need to use special anchor clamps.
Tuning system in the general television set is a kind of tuner of mechanical rotation normally, and also be that they are mechanical parts, thereby many shortcomings are arranged, for example:
ⅰ) may there be mechanical wear and breaks, cause the life-span of parts to reduce.
ⅱ) need be connected tuner and integrated package with transformer with intermediate frequency coil.
ⅲ) because common tuning system is a mechanical part, it needs bigger space and bigger weight is arranged.
ⅳ) owing to be mechanical part, it needs manual setting, and transformer and intermediate frequency coil also all need debugging.
ⅴ) need with two tuners that separate for UHF and VHF reception.
So, the broad sense purpose of our invention is, can in color television set, utilize the synthetic black and white electronic chip tuner of voltage first, no longer need to debug operation, and can utilize black and white Monomax subsystem integrated package by means of black and white small chip tuner.Black and white small chip tuner and black and white Monomax subsystem integrated package do not need by intermediate frequency coil or transformer and directly are connected, therefore they only take very little space and in whole working life good stability are arranged, because be more inexpensive, in light weight and need the electronic unit on production line, debug, therefore can do following description to it:
ⅰ) the electronic chip tuner among the present invention is a single tuning system that can be used for UHF and VHF reception.
ⅱ) the used electronic chip tuner of the present invention is a widget, compares it in light weight and take less space with the system in past.
ⅲ) the low price of electronic chip tuner, and be to debug in advance, because this tuning system does not use intermediate frequency transformer and intermediate frequency coil, therefore improved production efficiency, and then reduced the cost of whole television set to greatest extent.
Composite video output signal among the present invention is from the IF(intermediate frequency) the 5.5MHz trapper of output takes out, to obtain required combination video signal peak-to-peak value voltage, the biasing of the 7th pin and the 8th pin is through changing, the resistance that is external bias resistance changes, and added an additional resistance, to provide smooth composite video output signal.Because the Monomax integrated package during fabrication through very accurate debugging, no longer needs AFT(automatic frequency tuning) switch.
Used a small-sized black and white electronic chip tuner, it is minimum to make the cost of color TV harmonization unit reduce to, and provides a single tuner for UHF and VHF receive.Only after having utilized black and white Monomax integrated package to produce to be used for the combination video signal of miniature electric tuner, just might be used in this tuner in the color television set.
The present invention has also reduced components and parts and color television set VIF(video intermediate frequency to greatest extent) and SIF(audio frequency intermediate frequency) additional mask of part, and the debugging of the precision during because of production of integrated circuits, picture quality also improves.It has simplified production process and after-sale service.
The Figure of description explanation:
Fig. 1 is the tuning circuit of television set of the present invention,
Fig. 2 is the intermediate level circuit of television set of the present invention,
Fig. 3 is the Voice ﹠ Video amplifying circuit of television set of the present invention,
Fig. 4 is the scanning circuit of television set of the present invention,
Fig. 5 is the picture tube interlock circuit of television set of the present invention,
Fig. 6 is the power circuit of television set of the present invention.
Shown in Fig. 1-6, the composite video output signal is taken from the 5.5MHz trapper of audio frequency intermediate frequency output, to obtain required combination video signal peak-to-peak voltage, integrated package 001(is a black and white Monomax integrated package) the 7th pin and the biasing of the 8th pin changed, the resistance that is external bias resistance is changed, and added additional resistance, to provide level and smooth composite video output.
Because black and white Monomax integrated package (being integrated package 001) very accurate debugging does not during fabrication need AFT(automatic frequency tuning) switch.
Similarly, small-sized black and white electronic chip tuner links to each other with integrated package 001 with the filtering separator by the Q101 intermediate frequency amplifier, provides a single tuner that can be used for UHF and VHF reception to us.Only, just might be used in this tuner in the color television set owing to used small-sized black and white electronic chip tuner and black and white Monomax integrated package (being integrated package 001).
In order to make the work of small-sized black and white electronic chip tuner, need 0 to 30V voltage, this voltage is by to the dividing potential drop of 100V alternating voltage and obtain from kickback transformer SW by means of integrated package 001, utilize rectifier and 30V voltage-stabiliser tube that it is converted to the 30V direct voltage again, shown in integrated package among the figure 005.Like this, these parts also can be worked with the 12V dc-battery.
The present invention has also reduced components and parts and color television set VIF(video intermediate frequency to greatest extent) and SIF(audio frequency intermediate frequency) additional mask of part, the precision when also making owing to integrated package (being integrated package 001) is simultaneously debugged and has been improved picture quality.The present invention has just simplified production process and after-sale service like this.
