A system of the power-driving device is provide with two critical yield values, the power-driving device working in a daytime model or evening model can be judged according to the critical yield value which is adjusted automatically by the system, and the optical filter can be moved by different ways relatively to the working models. The power-driving device of the camera optical filter of the utility model has the advantages that the life expectancy can be ensured, and the switching time is fast, the noise is small, the daytime model or evening model switching requirements can be finished quickly.
Description
[technical field]
The utility model relates to a kind of video camera optical filter Power Drive Unit of video camera optical filter Power Drive Unit, particularly a kind of magnetically-actuated.
[background technology]
The day and night pattern video camera of monitoring trade generally adopts direct current generator to drive the mode of removable optical filter at present, and it utilizes a direct current generator to be connected with the switching optical filter by corresponding mechanical driving device with mated gear, forms movable-component, moves together.The voltage of opposed polarity makes the direction of motor rotation difference, makes gear along the different directions transmission, moves thereby drive optical filter.The defective of this technical scheme is the physical construction more complicated, poor reliability, and the life-span short (only can use continuously 4000～5000 times), optical filter traveling time long (greater than 500ms), and noise is bigger, and control is complicated, still can not scale use.
Therefore, be necessary to provide a kind of simple in structure, the video camera optical filter Power Drive Unit that serviceable life is long.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of video camera optical filter Power Drive Unit of video camera optical filter Power Drive Unit, particularly a kind of magnetically-actuated.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of video camera optical filter Power Drive Unit, the optical filter that is used for mobile camera, it comprises optical filter, coil, magnet, coil input lead and control circuit board, described coil parcel mobile spectral filter, by described control circuit board and coil input lead is the voltage of described coil input opposed polarity, and the power that produces different directions in described magnet makes optical filter move to different directions.The default of described Power Drive Unit has two critical gain values, and it judges that according to the self-regulating yield value of system Power Drive Unit works in daytime or night mode, and corresponding above-mentioned mode of operation mobile spectral filter in a different manner.
Video camera optical filter Power Drive Unit of the present utility model, life-span is secure, test through reality, switch back and forth and can reach more than 20000 times, normally use by reality and to switch a life-span evening on daytime back and forth and can reach 20 years, and switching time fast (about 100ms), noise is little, can finish day and night mode switch requirement rapidly.

Fig. 1 is the structural representation of the utility model video camera optical filter Power Drive Unit.
Fig. 2 is the process flow diagram that the utility model video camera optical filter Power Drive Unit was judged night on daytime.
Fig. 3 is the start process flow diagram of the utility model video camera optical filter Power Drive Unit.
[embodiment]
The utility model will be further described below in conjunction with accompanying drawing.
In the prior art, generally be to adopt direct current generator to drive the mode of removable optical filter, it utilizes a direct current generator to be connected with the switching optical filter by corresponding mechanical driving device with mated gear, forms movable-component, moves together.The voltage of opposed polarity makes the direction of motor rotation difference, makes gear along the different directions transmission, moves thereby drive optical filter.
And the utility model adopts novel magnetically-actuated switching mode to have series of advantages based on the day and night pattern video camera of DPS technology, but uses through test scale scrupulously.
See also Fig. 1, video camera optical filter Power Drive Unit of the present utility model comprises optical filter 11, coil 13, magnet 15, coil input lead 17 and control circuit board.Above-mentioned magnet 15 is two permanent magnets, and this coil 13 is the lamination enameled wire, and its parcel mobile spectral filter 11 and support are placed by fixed form.Described optical filter 11, coil 13 movably are positioned on the magnet 15.Described coil input lead 17 is connected with coil 13, and described coil input lead 17 is connected with control circuit board.By coil input lead 17 and control circuit board is the voltage of coil 13 input opposed polarities, and the power that produces different directions in magnet 15 makes filter supporter move to different directions, drives optical filter 11 and moves.
See also Fig. 2, sensor and disposal system make the change in gain of system according to the variation of light, and the strong more gain of light is more little, system software is set two critical gain values earlier, when the self-regulating yield value of system during greater than the upper limit yield value set, expression light a little less than, thereby regard as evening.At this moment, software output low level on the output pin position; Otherwise when the self-regulating yield value of system during less than the lower limit yield value set, expression light is stronger, thereby regards as daytime.At this moment, software is exported high level on the output pin position, and basis mode as shown in Figure 2 drives again.
See also Fig. 2 and Fig. 3, software setting by current gain value and default a certain yield value relatively, if the result who judges be less than a certain output pin position output high level of system, otherwise this pin position output low level then.And the hardware driving circuit has only one, if the output of pin position is high level, then the enameled wire both end voltage of magnetically-actuated is 10V, and promptly day mode is installed mobile spectral filter to the inside, and sensor normally covers optical filter.If the output of pin position is low level, then the enameled wire both end voltage is-10V, and promptly night mode is installed and removed optical filter laterally, and sensor directly contacts extraneous light, and can respond to Infrared.So, can make the mobile spectral filter support move, and drive removable optical filter and move to different directions.
It is as follows to produce the technology assemble flow that realizes:
1. removable optical filter is put on the filter supporter;
2. whole removable optical filter external member is put on the sensor on the whole video camera header board, and is fixed on the shell with screw;
3. on the tailgate of the connecting line that enamelled wire connection is come out through whole video camera, promptly finish assembly work;
4. life-span and functional test: video camera is placed on normal demonstration the under the ordinary ray by following embodiment with video camera, again in the dark surrounds of testing laboratory, optical filter can automatically switch, image transfers white-black pattern to, move on under the arm's length relationship, optical filter can switch back again, and normal picture shows.And by manually importing the high-low level signal testing life-span.
