Description
Technical field
The present invention relates to the light and the integrated control device of video switch that use in a kind of image capturing system.
Background technology
At present in the image capturing system, under the different light combination condition to the shooting of a certain target different angles, generally the mode of Cai Yonging is manually to control the variation and the shooting angle of light.Illumination condition of every change is taken, and needs people's intervention; Shooting angle of every change also needs people's intervention.Adopt this mode to carry out image acquisition and not only make shooting personnel's workload very big, and can not realize that a certain target that is taken is carried out multi-angle to automatically snap continuously under any illumination combination condition; Shooting efficient is low, can not adapt to the needs that automated image is gathered.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of light and the integrated control device of video switch, it can carry out different angles to subject and automatically snaps continuously under any illumination combination, and easy and simple to handle, control flexibly, reliability is high, the speed and the dirigibility that improve image acquisition.
For solving the problems of the technologies described above, the integrated control device of light of the present invention and video switch comprises communication interface circuit, single chip circuit, lighting control circuit, video switch circuit, watchdog circuit, control decoding scheme; Wherein, the communication interface circuit receives the control command from computing machine, and carries out conversion of signals and send single chip circuit to; Single chip circuit receives earlier and resolves the illumination compound command, sends control command then and outputs to decoding scheme, and receiving also again, analysis diagram sends control command then and outputs to decoding scheme as acquisition; Decoding scheme is resolved the control command of single-chip microcomputer and is exported control signal respectively to lighting control circuit and video switch circuit by the control requirement; Thereby opening or closing of illuminating lamp of lighting control circuit control realized desired illumination condition; Video switch circuit video camera of gating is on request taken, and delays time simultaneously and uploads the image of clapping; Watchdog circuit is used for monitoring and guaranteeing the single-chip microcomputer operate as normal.
When using the integrated control device of light of the present invention and video switch and taking, computing machine sends the illumination compound command earlier, and control device is resolved this order and controlled every group of lamp by its inner solid-state relay and opens or closes, and realizes desired illumination combination; Computing machine sends the image acquisition order then, and control device is the video camera on each road of gating successively, gathers the image that is transmitted up by this road video camera simultaneously, so far finishes once the shooting to a certain subject different angles under certain illumination condition.Can finish image acquisition easy, flexible, rapidly, and when work the reliability height.
Description of drawings
Fig. 1 is the theory diagram of light of the present invention and the integrated control device of video switch.
Embodiment
Referring to Fig. 1, the integrated control device of light of the present invention and video switch is made up of communication interface circuit 1, single chip circuit 2, lighting control circuit 3, video switch circuit 4, watchdog circuit 5, control decoding scheme 6 and power circuit 7; Communication interface circuit 1 connects single chip circuit 2, single chip circuit 2 connects watchdog circuit 5 and control decoding scheme 6, control decoding scheme 6 connects lighting control circuit 3 and video switch circuit 4, and lighting control circuit 3, video switch circuit 4 and control decoding scheme 6 are all worked under single chip circuit 2 controls.
Communication interface circuit 1 receives control command and carries out conversion of signals.Single chip circuit 2 is resolved control command, control communication and relay on-off.Lighting control circuit 3 control illuminating lamps open or close.Certain video camera of video switch circuit 4 gatings.Watchdog circuit 5 monitoring single-chip microcomputer operations also guarantee its operate as normal.Control decoding scheme 6 is resolved control command, the output control signal of single-chip microcomputer.Power circuit 7 provides power supply for the The whole control device.
During work, communication interface circuit 1 is accepted to send single chip circuit 2 to from the control command of computing machine and it, again by single-chip microcomputer 2 resolve command, send signal then and give lighting control circuit 3 and video switch circuit 4, break-make control illuminating lamp by lighting control circuit 3 output relays is realized desired illumination combination, by certain video camera of break-make gating of video switch circuit 4 output relays, gather the image that this road video camera is transmitted up simultaneously.Image (vision signal) uploads to computing machine by communication interface circuit 1, and communication interface circuit 1 joins with computing machine.The present invention can use a plurality of illuminating lamps and a plurality of video camera simultaneously, is installed in different angles respectively, and lighting control circuit 3 output terminals are corresponding one by one continuous with each illuminating lamp, and video switch circuit 4 output terminals join with each video camera is corresponding one by one.
Concrete workflow is as follows:
1. the illumination combination control command sent of communication interface circuit 1 receiving computer and send single-chip microcomputer to.
2. single chip circuit 2 is resolved illumination combination control command, is sent control signal, opens or closes by lighting control circuit 3 each illuminating lamps of control, thereby realizes desired illumination condition.
3. communication interface circuit 1 is accepted the image acquisition order that computing machine sends and is sent single-chip microcomputer 2 to, and single-chip microcomputer 2 is resolved image command, sent control signal, by video switch circuit 4 gatings the No. 1 video camera, delays time simultaneously and uploads the image of clapping.
4. single chip circuit 2 sends control signal, by video switch circuit 4 gatings the No. 2 video camera, delays time and uploads the image of clapping.
5. single chip circuit 2 sends control signal, by video switch circuit 4 gatings the No. 3 video camera, delays time and uploads the image of clapping.
……………………………………
6. single chip circuit 2 sends control signal, by video switch circuit 4 gating n road video cameras, delays time and uploads the image of clapping.
7. repeat above-mentioned steps 1～6.
So far, finished shooting to a certain subject each different angles under any illumination condition combination.The present invention is easy and simple to handle really as can be seen as mentioned above, control is flexible, it is rapid to take pictures, and is very strong light of a kind of practicality and the integrated control device of video switch.
