In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effect apparent by embodiment of the present utility model is described in detail.
Fig. 1 is the schematic diagram of the utility model duplicate supply camera.
Embodiment
For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
As shown in Figure 1, duplicate supply camera of the present utility model comprises: camera body 1, circuit main board 2, camera lens 3, and a pair of voltage input module 4, described circuit main board 2 is located at body 1 inner space, camera lens 2 is embedded on this body 1, described pair of voltage input module 4 electrically connects with circuit main board 2, and it further is provided with corresponding with it two voltage input end mouths 5.
Further, be provided with voltage conversion circuit (not shown) in described pair of voltage input module 4.Described pair of voltage input end mouth 5 is located at camera body 1 outside, this port is supported two kinds of different power supply access waies, and it can be electrically connected with the city by transformer, incoming transport 24V voltage, perhaps, insert direct current 12V voltage by inserting the mode of series battery.This port organization is simple, highly versatile, exchange 24V voltage or direct current 12V voltage by the two voltage input modules 4 of this port input, input voltage is converted to the operating voltage of camera by the voltage conversion circuit in this module, and then be transferred to circuit main board 2, for this duplicate supply camera provides operate as normal required voltage.Adopt this duplicate supply input mode, can avoid traditional single power supply camera in the defective that has a power failure or circuit can't operate as normal when breaking down, for camera provides 24 hours uninterrupted power supplies, can under outage or outdoor non-transformer situation, continue continual operate as normal to guarantee this camera.
As a kind of selectivity embodiment of the present utility model, on described circuit main board 2, be connected with the filter system 6 that day and night automaticallyes switch, this filter system 6 that day and night automaticallyes switch is provided with between one day filter disc and filter disc (not shown) in one night, and this filter disc is with respect to described camera lens 3 front end settings.Be provided with light-inductive circuit and automatic switch-over circuit in the described automatic switchover filter system 6, this automatic switch-over circuit and circuit main board 2 electrically connect.This light-inductive circuit is the induction light line strength at any time, judges that this moment, light intensity belonged in the daytime or Night, and automatic switch-over circuit is according to the judgement of light-inductive circuit, carries out in the daytime automatically or the switching of Night.If the light-inductive circuit inductance is higher than a certain scope to light intensity, this moment, light intensity belonged to a day inter mode, then automatic switch-over circuit between controll day filter disc block front end at camera lens 3, the non-visible light of this filter disc filtering in the daytime from the light of camera lens 3 transmissions, the colour cast of avoiding non-visible light to produce is to obtain the image quality better image; If the light-inductive circuit inductance to light intensity be lower than a certain scope, this moment, light intensity belonged to Night, then automatic switch-over circuit control filter disc at night blocks the front end at camera lens 3, this filter disc permission at night infrared light sees through, utilize the near infrared ray imaging, be implemented in night light than the purpose that still can obtain in the dark situation than picture rich in detail.In the present embodiment, described camera lens 3 can adopt automatic diaphragm lens.This automatic diaphragm lens has adopted up-to-date optical design method and special advanced technologies such as optical glass material, has eliminated the focal plane shift of visible light and infrared light.Therefore the light from visible region to the infrared light district can be realized sharp keen image in the imaging of same position of focal plane.And need not focus again after its disposable setting, more convenient to use easy to operate.When camera lens is installed under possible condition, consider that installation is not less than 1/2 inch camera lens, image can not produce dark angle so on the one hand, on the other hand, can strengthen photosensitive area and promote the effect at night, in order to avoid adopt little size camera lens to cause unnecessary waste.
As another kind of selectivity embodiment of the present utility model, on described circuit main board 2, be connected with a differential transfer transducer 7, camera body 1 is provided with twisted-pair feeder interface 8, and twisted-pair feeder links to each other with described differential transfer converter 7 by this interface.Utilize the differential transfer principle, this differential transfer transducer 7 equates the conventional video signals that spreads out of on the circuit main board 2 amplitude that is transformed into, opposite polarity vision signal, after the twisted-pair feeder transmission, at receiving terminal two opposite polarity vision signals are subtracted each other and to become traditional vision signal, this process can effectively suppress common mode disturbances, even under strong interference environment, its antijamming capability is good more than coaxial cable, same netting twine can not disturb each other, and adopt the twisted-pair feeder transmission means, it connects up convenient, long transmission distance, the transmission quality height, cable utilance height.
In sum, the duplicate supply camera that the utility model provides, adopt the duplicate supply input mode that camera is powered, versatility is stronger, the selection of convenient different supply power modes, can also avoid for camera provides 24 hours uninterrupted power supplies, can under outage or outdoor non-transformer situation, continuing continual operate as normal to guarantee this camera having a power failure or the circuit defective that camera can't operate as normal when breaking down.Simultaneously, this camera has and day and night switches filter disc, have the automatic mode handoff functionality, can automatically switch in the daytime or Night, can reach color rendition, selectivity printing opacity, in darker environment, improve picture brightness to obtain the purpose of image quality better image.In addition, the utility model camera adopts the twisted-pair feeder transmission means, and wiring is convenient, cable utilance height, and its long transmission distance, transmission quality height have the strong characteristics of antijamming capability simultaneously.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model accompanying Claim.
