In this Fig. 1, the operation interface that is arranged in the human-computer interaction interface 1 of rear end can be existing General Purpose Interface, in the interface of more existing common softwares, the parameter that has some not re-use, as the IRIS parameter on the existing monitoring software interface, because in the past the size of the setting value by this parameter of IRIS on this interface was used for controlling the IRIS size of camera lens the inside, controlled the sensitive volume of video camera CCD with this.But because the IRIS size of camera lens the inside is to be controlled by video camera basically now, the IRIS parameter on the monitoring software interface has not just re-used, and the utility model can utilize this parameter to come Long-distance Control laser facula size.In like manner, the headlamp switch parameter on the existing interface is used for controlling the switch of laser.
Wherein, the principle of the light source control mechanism 4 in the utility model as shown in Figure 2, the light source control mechanism 4 of described laser night vision illuminator comprises light source driving mechanism 41 and signal sampling mechanism 42 and zoom lens 43, the light source S that is arranged in zoom lens 43 in described light source driving mechanism 41 and the laser night vision illuminator links to each other, driving light source S moves forward and backward in the zoom lens 43 in the laser night vision illuminator, changes the size of laser facula with this.Described signal sampling mechanism 42 links to each other with described illumination driving mechanism 41, is used to gather the size of hot spot, and with this hot spot signal that collects output.Wherein, light source driving mechanism 41 receives from the control information in the decoder 3, moves forward and backward according to the driving light source that requires of this control information.The signal of the representative spot size that described signal sampling mechanism 42 will sample sends to decoder 3, or by decoder stores and turn back to and be shown to the operator in the man-machine interface.
Wherein, light source driving mechanism 41 can be motor, as stepper motor etc.Signal sampling mechanism 42 can be for being used to gather the potentiometer and the interlock circuit of electric potential signal, or other can gather the sensor of motor position, as photoelectric sensor, and magnetic induction sensor etc.
Fig. 3 is the structural representation of a specific embodiment of light source control described in the utility model mechanism.Described light source control mechanism comprises drive motors 410, potentiometer 420 and drive disk assembly 411, wherein, drive disk assembly 411 comprise the main driving wheel 412 that is positioned on drive motors 410 output shafts, on the sliding end that is positioned at described potentiometer 420 from drive 413 be connected main driving wheel 412 and from the travelling gear 414 of drive 413.Main driving wheel 412 and be meshed with travelling gear 414 respectively from drive 413.
Described light source control mechanism also comprises zoom lens 43, and as shown in Figure 4, Fig. 4 is the part-structure cut-away view of Fig. 3.Zoom lens 43 comprise shell 431, with travelling gear 414 stationary sleeve 432, chute 433 that sleeve is moved forward and backward, described light source S is fixed on the sleeve 432.
The control instruction of drive motors 410 Rcv decoders 3 is carried out forward or reverse.For example, when drive motors 410 was just changeing, the main driving wheel 412 on drive motors 410 output shafts drove travelling gear 414 and rotates, and travelling gear 414 drives sleeve 432 and moves forward or backward on chute 433.Because light source S, be fixed on the sleeve 432 as optical fiber, thereby light source S is also mobile forward or backward, because lens 61,62 positions in the zoom lens 43 are motionless, when the distance of light source S and lens 61,62 changed, the spot size of breaking forth from zoom lens 43 changed.
When travelling gear 414 rotates, what be meshed with it rotates from drive 413, thereby the sliding end that drives potentiometer moves, thereby the resistance of potentiometer changes, because the voltage at potentiometer two ends is certain, as 5V, thereby potentiometer output and mobile preceding different voltage signal, this voltage signal is corresponding with the distance that light source S moves, thereby corresponding with spot size.On behalf of the voltage signal of spot size, potentiometer will send to decoder 3, be stored and turned back in the man-machine interface 1 by decoder 3 to be shown to the operator.
In the utility model, described decoder 3 not only can be controlled The Cloud Terrace and camera lens as prior art, and can control the light source control mechanism 4 in the utility model, thereby realizes the Long-distance Control of laser facula.Principle as shown in Figure 5.Fig. 5 is the principle schematic of decoder in the system of the utility model night vision illumination system medium-long range control device.
In like manner, what the utility model can also Long-distance Control laser opening and closing, and its specific implementation method is to be provided with a switch, controls this switch by the output of decoder, as finishing by components and parts such as switch triode or relays.
The utility model is owing to have the function of Long-distance Control laser facula size, and the signal of the spot size of can sampling, and therefore, can control flexibly the control of this laser night vision illuminator.As, when the size of hot spot being adjusted to a certain value A1, will represent the voltage signal of potentiometer particular location B1 of the size of this hot spot to store, conveniently can get a code name in order to control, as NO1.In the time the size of hot spot need being adjusted to A1, only need to import this code name NO1 at the IRIS of human-computer interaction interface 1 parameter item, then the potentiometer in this light source control mechanism 4 arrives B1 place, position in the control lower slider of decoder 3, thus the size of hot spot is A1.
When carrying out the monitoring of a plurality of positions by a watch-dog, the advantage of such scheme will be more obvious: the spot size difference of each monitoring position correspondence, if according to traditional way, whenever change a monitoring position, and all to readjust the size of hot spot.And utilization the utility model, only need be noted the particular location Bi of the potentiometer of corresponding different spot size Ai when adjusting each time, and each position is numbered.In monitor procedure, when need to which position are monitored, only need the numbering NOi of input corresponding to this position, then automatically the size of hot spot is adjusted to Ai.
, also other parameter values can be stored simultaneously when representing the parameter value of spot size in storage, as light intensity magnitude, apart from distance etc.
The utility model can be realized fixed point monitoring, unmanned, and can carry out automatic cruising.Therefore, alleviated monitor staff's labour intensity to greatest extent.
The control software that cooperates monitoring to use in the utility model can adopt common software, as the control software that can use video server 2 to carry, only IRIS parameter button that need not re-use in the above-mentioned common software and headlamp switch use and carry out above-mentioned Long-distance Control.Therefore, need not change human-computer interaction interface, highly versatile.
Need to prove at last; above embodiment is only unrestricted in order to explanation the utility model; although the utility model is had been described in detail with reference to preferred embodiment; but those of ordinary skill in the art is to be understood that; the modification of under the prerequisite that does not break away from the utility model scope the utility model being carried out or be equal to replacement all should belong within the protection domain of the utility model claim.
