It is provided with master control circuit, can detect VGA video input end department's signal source and the receiving equipment's of output port department resolution ratio, it is provided with the signal processing switch, can transmit video signal, and can carry out the adjustment of resolution ratio in the alerting signal source.
Description
[technical field]
The utility model relates to a kind of signal shifter, particularly relates to a kind of VGA switch.
[background technology]
VGA switch plays huge effect at communication technical field, but the resolution of the VGA vision signal of various signal source such as picture mobile phone, computer etc. is not identical, if signal source is not mated with the resolution of receiving equipment (being generally display or projecting apparatus), the video that receiving equipment will be caused to show has problem, and general VGA switch cannot solve such technical problem.
[utility model content]
The purpose of this utility model is the deficiency effectively overcoming above-mentioned technology, provides a kind of VGA switch, and the resolution of its energy sensed signal sources and receiving equipment, the adjustment of resolution is carried out in alerting signal source.
The technical solution of the utility model is achieved in that it comprises VGA video inputs, integrating circuit, governor circuit, signal transacting switch and output port, its improvements are: described VGA video inputs and described integrating circuit are electrically connected, described integrating circuit is electrically connected with described governor circuit and signal transacting switch respectively, described governor circuit and described signal transacting switch are electrically connected, and described output port is electrically connected with described governor circuit and signal transacting switch respectively.
In said structure, described VGA video inputs has 8.
In said structure, described integrating circuit is also electrically connected with shaping circuit, and this shaping circuit is electrically connected with described governor circuit and signal transacting switch respectively.
The beneficial effects of the utility model are: it is provided with governor circuit, can detect the resolution of VGA video inputs place's signal source and output port place receiving equipment; It is provided with signal transacting switch, energy transmission video signal, and the adjustment of resolution is carried out in energy alerting signal source; Its VGA video inputs has 8, and the signal source of support is many.
[accompanying drawing explanation]
Fig. 1 is functional block diagram of the present utility model.
[embodiment]
Below in conjunction with drawings and Examples, the utility model will be further described.
With reference to shown in Fig. 1, a kind of VGA switch that the utility model discloses, it comprises 8 VGA video inputs, integrating circuit, governor circuit, signal transacting switch and output port, described VGA video inputs and described integrating circuit are electrically connected, described integrating circuit is electrically connected with described governor circuit and signal transacting switch respectively, described governor circuit and described signal transacting switch are electrically connected, described output port is electrically connected with described governor circuit and signal transacting switch respectively, described integrating circuit is also electrically connected with shaping circuit, this shaping circuit is electrically connected with described governor circuit and signal transacting switch respectively.
The utility model is mainly used in Multi-media video teaching or video monitoring, in Multi-media video teaching, the signal source that VGA video inputs connects is video teaching end, this video teaching end can be 1 to 8, the receiving equipment that output port connects is projecting apparatus, described integrating circuit and the vision signal of shaping circuit to video teaching end are optimized, the video resolution of described governor circuit to projecting apparatus and video teaching end detects, if find that the video resolution of certain video teaching end is not identical with the video resolution of projector, governor circuit will send instruction to described signal transacting switch, signal transacting switch will remind this video teaching end to carry out the adjustment of VGA signal resolution, signal transacting switch again suitable VGA Signal transmissions to projecting apparatus, in order to avoid there is the unmatched problem of resolution.
Described above is only preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, can occur various distortion and amendment, all those of ordinary skill in the art, according to describing retouching, the amendment made above or equivalent replacing, all belong to the scope that the utility model is protected.
