Description

Can select the image detecting module of different reconnaissance ranges

Technical field

The present invention is relevant with the image detecting module, refers to especially a kind of image detecting module of selecting different reconnaissance ranges.

Background technology

TaiWan, China is openly numbered No. 200951884 Patent Case and is exposed a kind of " surveillance and its control method ", it mainly is to utilize two sensors that near the zone the surveillance is divided into four different sensing regions, when object entered so-called overlapping sensing region, control unit will make photographic goods photograph.

Yet, the surveillance of aforementioned patent case is usually because the difference of setting up environment, cause the scope of overlapping sensing region to have excessive or too small situation, and just have no idea the overlapping sensing region is adjusted after complete setting up, therefore, the design of aforementioned patent case is difficult to satisfy the demand of user under different behaviours in service.

Summary of the invention

The technical problem to be solved in the present invention is, can't satisfy the defective of the demand of different behaviours in service for surveillance in the prior art, a kind of image detecting module is provided, and it can select different reconnaissance ranges according to actual state, to satisfy the different needs of user.

The present invention is that the technical scheme that its technical problem of solution adopts is, a kind of image detecting module is provided, and includes eyeglass, two transducers, and controller.This eyeglass has the first transparent area and the second transparent area, the quantity that the quantity that this first transparent area can allow light pass through can allow light pass through greater than this second transparent area; These two transducers are located at the same side of this eyeglass and respectively to should the first transparent area and this second transparent area, can are received light and send trigger signals via this first transparent area and this second transparent area respectively; This controller is electrically connected this two transducers, and selectively receives the wherein trigger signals of this transducer, to satisfy different behaviours in service.

In an embodiment of the present invention, this controller can be electrically connected with temperature sensor, and this controller can be adjusted the bound comparative voltage through the variations in temperature that this temperature sensor is detected; In addition, this controller can be electrically connected with camera, allows this controller can send out the shutter signal when receiving the trigger signals of this transducer and takes pictures to this camera.

Implement image detecting module of the present invention, has following beneficial effect: can come the larger transducer of choice for use reconnaissance range or the less transducer of reconnaissance range to detect according to actual state, really satisfy the different user demand of user in order to change different detecting shot region; And it can be adjusted for ambient temperature, can't trigger or the situation of false triggering to avoid producing.

Embodiment

In order to describe structure of the present invention, feature and effect place in detail, hereby enumerate a preferred embodiment and cooperate following description of drawings such as rear.

See also Fig. 1, be the image detecting module 10 that a preferred embodiment of the present invention provides, include eyeglass 20, two transducers 30, and controller 40.

Eyeglass 20 is made by transparent material, the local surfaces of eyeglass 20 is coated with light-proof material and forms light tight district 22, uncoated have the position of light-proof material then to form the first transparent area 24 and the second transparent area 26, wherein, the first transparent area 24 is that three the first transparent blocks 242 by the space are formed, the second transparent area 26 is that two the second transparent blocks 262 by the space are formed, spacing between the second transparent block 262 is less than the spacing between the first transparent block 242, by this, the quantity that the quantity that the first transparent area 24 can allow light pass through can allow light pass through greater than the second transparent area 26, as shown in Figures 2 and 3.

Two sensors 30 at this all take the electric type infrared inductor of Jiao as example, be located at the same side and corresponding the first transparent area 24 of difference and second transparent area 26 of eyeglass 20, so that two sensors 30 can receive respectively the light of varying number via the first transparent area 24 and the second transparent area 26, wherein 30 angular ranges that can detect of one group of transducer can reach about 45 degree, the angular range that other one group of transducer can be detected is only about 10 degree, shown in second and three figure, after transducer 30 receives light, can see through sensing circuit 50 with the signal amplification and produce different trigger signals, as shown in Figure 4.

Controller 40 is electrically connected two sensors 30, can receive the wherein trigger signals of one group of transducer 30 via sensing circuit 50, controller 40 also is electrically connected with camera 60, can send out the shutter signal to camera 60 action of taking pictures after receiving trigger signals.

By said structure as can be known, the user can come choice for use reconnaissance range larger transducer 30 or the less transducer 30 of reconnaissance range to detect according to actual state, really satisfies the different user demand of user in order to change different detecting shot region.On the other hand, because transducer 30 has different reaction signals under different temperature environments, controller 40 can be electrically connected with temperature sensor 70 again, as shown in Figure 4, allow controller 40 can see through the ambient temperature that temperature sensor 70 detects and adjust the bound comparative voltage of sensing circuit 50, to avoid transducer 30 to produce to trigger or the situation of false triggering.

Please consult again Fig. 5, the image detecting module 80 that provides for the second preferred embodiment of the present invention, its primary structure and above-described embodiment are roughly the same, precisely because it is that two transparent blocks 842 by the space are formed that difference is the first transparent area 84 of

eyeglass

82,86 of the second transparent areas are that single transparent block forms, and so can allow equally light pass through the quantity of the first transparent area 84 greater than the quantity by the second transparent area 86; In addition, be provided with dividing plate 90 between the two sensors 88, and wherein one group of transducer 88 by 90 on dividing plate around, as shown in Figure 6, by this, the reconnaissance range of two sensors 88 can separate clearly and come, to avoid producing the situation of phase mutual interference.

The present invention takes off disclosed constituent components among the embodiment in front, only for illustrating, is not the scope that limits this case, the alternative or variation of other equivalent elements, and the claim that also should be this case contains.
