Detailed ways

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

The problem caused by the shooting is unclear, which is not conducive to improving the security effect. Therefore, the control part 2 will continue to control the independent movement of the lighting unit 3, so that the lighting unit 3 can shine on various positions within the monitoring range of the camera 4, so that within the monitoring range of the camera 4 The monitored objects can be illuminated by the lighting unit 3 all the time.

The present invention separates the camera 4 and the lighting unit 3 into two independent individuals. After the camera 4 captures the monitoring object, the monitoring unit 1 will drive the camera 4 to rotate according to the movement of the monitoring object, so that the monitoring range of the camera 4 becomes wider.

Specifically, when the camera head 4 rotates within the set horizontal rotation angle range, the first push rod 24 is in an extended state, so that the fifth gear 25 is meshed with the third gear 21, so that the third gear 21 is driven to rotate , the fifth gear 25 can also rotate synchronously, so that the fifth gear 25 drives the driving rod 26 to rotate synchronously, and the driving rod 26 can drive the second push rod 29 to move along the track of the slideway 27, and the second push rod 29 can The lighting unit 3 is driven to rotate synchronously with the camera 4 to achieve the effect of supplementing light to the camera 4 at all times.

The expansion and contraction of the second push rod 29 will be transformed according to the signal captured by the camera 4 of the monitored object. As the monitored object gradually moves away from the camera 4 within the monitoring range of the camera 4, the second push rod 29 will shrink, so that the front end of the lighting unit 3 Lift it up so that it can be irradiated to a farther distance. On the contrary, when the monitored object is gradually approaching the camera 4 within the monitoring range of the camera 4, the second push rod 29 will be extended, so that the front end of the lighting unit 3 is lowered so that it can be irradiated closer. That is, the lighting unit can not only swing horizontally, but also swing up and down.

When the camera head 4 rotates horizontally to the set angle (limit angle), the first motor 13 stops working, and now the first push rod 24 shortens, so that the fifth gear 25 is meshed with the fourth gear 22, and then the second motor 23 starts Work, the second motor 23 drives the second shaft 20 to rotate, the second shaft 20 drives the fourth gear 22 to rotate, the fourth gear 22 drives the fifth gear 25 to rotate, and the fifth gear 25 moves the second gear through the lever 26 The push rod 29 moves along the track of the slideway 27, and the lighting unit 3 can rotate horizontally or vertically. Supplementing light at any position makes the monitored objects within the monitoring range of the camera 4 always be illuminated by the lighting unit 3, which not only improves the shooting clarity of the camera 4, but also plays a warning role, thereby effectively improving the security effect.

Preferably, the lighting unit 3 includes a bottom bracket 30, the installation box 11 and the bottom bracket 30 are connected by a ball hinge, and the bottom bracket 30 is provided with a cylinder 31 on the side facing the monitoring area of the camera 4 , the cylinder 31 is provided with a light source 32, and the end of the cylinder 31 away from the base 30 is provided with a lens 33; specifically, when the camera 4 needs to be supplemented with light, the light source 32 is energized to generate bright light, and the bright light passes through the lens 33 is refracted out of the cylinder 31 so that the monitoring area of the camera 4 can be supplemented with light, and the adjustment member 2 regulates the rotation of the bottom support 30 on the installation box 11 to achieve the position of regulating the bright light irradiation.

Further, the two ends of the cylinder 31 in the longitudinal direction are symmetrically provided with electromagnetic rings 310, the light source 32 is provided with a magnet ring 311, and the magnet ring 311 is in sliding contact with the inner wall of the cylinder 31, and the electromagnetic ring 310 is in contact with the magnet. The opposite magnetic poles of the ring 311 are the same, and the upper and lower parts of the surface of the bottom bracket 30 are symmetrically provided with a resistance piece 312, and the installation box 11 is connected with the resistance piece 312 through an electrode piece 313. 312 is electrically connected to the electromagnetic ring 310 at a close position, and the resistance sheet 312 located at the lower part of the base 30 is electrically connected to the electromagnetic ring 310 at a distant position.

Preferably, the resistance of the resistance sheet 312 located on the upper part of the base 30 increases gradually in the clockwise direction, and the resistance of the resistance sheet 312 located on the upper part of the base 30 gradually increases in the counterclockwise direction.

Concretely, the distance between the light source 32 and the lens 33 determines the gathering and divergence of the light, and the light intensity does not need to be too high when illuminating close-range objects, otherwise the monitoring object photographed by the camera 4 will be whitish because of the high brightness, and the When irradiating a distant object, too much divergence of the light will reduce the brightness of the light, causing the monitored object captured by the camera 4 to be dark. Therefore, it is necessary to control the distance between the light source 32 and the lens 33 according to the actual situation at all times, so that the light source 32 is opposite to the camera 4. The fill light effect when shooting is better.

When it is necessary to supplement light to the camera 4 at a short distance, the light source 32 and the lens 33 need to be close together. At this time, the second push rod 29 is extended to push the bottom bracket 30 to rotate, so that the front end of the cylinder 31 is lowered, and at this time it is positioned at the bottom bracket. The electrode piece 313 on the upper part of the 30 will also move from the position where the resistance piece 312 in contact with it has a large resistance to a position where the resistance is small, so that the current passing into the electromagnetic ring 310 close to the bottom bracket 30 becomes larger, and the electromagnetic ring 310 produces The magnetic force becomes larger, and the electrode sheet 313 positioned at the lower part of the bottom bracket 30 will move from the position where the resistance sheet 312 in contact with it has a small resistance to a position where the resistance is large, so that the electric current passed into the electromagnetic ring 310 away from the bottom bracket 30 becomes smaller, The magnetic force produced by the electromagnetic ring 310 becomes smaller, so that the magnetic ring 311 on the light source 32 will move towards the electromagnetic ring 310 direction with little magnetic force, and the light source 32 will approach the lens 33, because the structural characteristics of the lens 33 can emit light to the light source 32. The light can diverge, so the monitoring objects at close range will be illuminated more clearly.

When it is necessary to supplement light to the camera 4 at a long distance, the light source 32 and the lens 33 need to be far away from each other. At this time, the second push rod 29 shortens and pulls the bottom bracket 30 to rotate, so that the front end of the cylinder 31 is lifted. The electrode sheet 313 on the upper part of the 30 will also move from the position where the resistance sheet 312 in contact with it has a small resistance to a position where the resistance is large, so that the current passing into the electromagnetic ring 310 close to the bottom bracket 30 becomes smaller, and the electromagnetic ring 310 produces The magnetic force becomes smaller, and the electrode sheet 313 positioned at the lower part of the bottom bracket 30 will move from the position where the resistance sheet 312 in contact with it has a large resistance to a position where the resistance is small, so that the electric current passed into the electromagnetic ring 310 away from the bottom bracket 30 becomes larger, The magnetic force produced by the electromagnetic ring 310 becomes larger, so that the magnetic ring 311 on the light source 32 will move towards the electromagnetic ring 310 with little magnetic force, and the light source 32 will be far away from the lens 33. The light plays a gathering role, so the distant monitoring object will be concentratedly illuminated by the gathered light, so that the monitoring object photographed by the camera 4 is clearer.
