Description

[0002] A multi-stage PAN-Tilt system having a high-

The present invention relates to a fan-and-tilt system having a high-speed multi-stage fan function, and more particularly, to a fan-and-tilting system in which a driving device 110 is driven by a pan and tilt, A first fan operation unit 130 connected to the tilt operation unit 120 to operate the tilting operation unit 120 to operate as a PAN, a tilt operation unit 120 for performing tilt operation of the tilt operation unit 120; And a second fan operation unit 140 connected to the first fan operation unit 130 to operate the first fan operation unit 130. [ And a fan-tilt system (100) having a fan function.

The pan-tilt system typically has a function of driving a device to be driven (PAN) and tilting (TILT), as disclosed in "Pan / tilt dome type camera (Korean Patent Registration No. 10-0558021) The conventional configuration of the pan-tilt system is typically composed of one tilt driving unit 10 and one fan driving unit 20 as shown in FIG.

On the other hand, the driving target device is a device having characteristics such as a surveillance camera that must be driven to track an object in the direction of an object, including a surveillance camera as well as various devices requiring various target tracking functions Various fire devices or laser devices).

In this case, when the object to be traced and to be aimed is an object moving at high speed, especially the fan operation speed plays an important role. That is, since the tilt function normally operates in a state of being horizontal to the ground, the tilt operation speed is not required to be high in the case of a majority of moving objects moving on the horizontal plane, For most moving objects moving on a horizontal plane, the fan operation speed must also be faster in order to track and direct objects moving at a higher speed.

However, in order to secure such a fast fan operation speed, in the past, only the operation speed of the fan operation drive means (for example, a stem motor or the like) was focused on. However, in this case, There is a problem that the operating speed is physically limited.

Korean Patent No. 10-0558021

It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a multi-stage fan operation structure capable of operating at a higher speed than a conventional fan-tilt system without using a special driving means that operates at high speed. A pan-tilt system having a high-speed multi-stage fan function capable of tracking an object moving at a high speed in driving a device to be driven such as a camera or a laser, We do what we provide.

In order to achieve the above object, a fan-and-tilt system having a high-speed multi-stage fan function according to the present invention is a fan-and-tilt system in which a device to be driven is driven by a pan and a tilt, A tilt operation unit 120 for tilting the target device 110 and a first fan operation unit 120 connected to the tilt operation unit 120 for operating the tilting operation unit 120, And a second fan actuating part 140 connected to the first fan actuating part 130 to operate the first fan actuating part 130 as a PAN, .

Also, at the normal speed fan operation, only either the first fan operation unit 130 or the second fan operation unit 140 performs the fan operation, and at the time of high speed fan operation, the first fan operation unit 130 And the second fan actuating part 140 interlock with each other and operate as a fan.

The tilting operation unit 120 may include a tilting shaft 121 that is driven by a tilting driving unit 123 to drive the tilting base 122, The first fan operation part 130 is characterized in that the tilt operation part 120 is installed on the first rotation base 131 through the first fan shaft 133 driven by the first fan drive means 132 And the second fan operation unit 140 is connected to the second rotation base 141 through the second fan shaft 133 driven by the second fan drive unit 142, Wherein the first fan shaft 133 and the second fan shaft 133 are located on an extension line of the first fan shaft 133 and the second fan shaft 133, respectively.

The tilting driving means 123, the first fan driving means 132, and the second fan driving means 142 are each constituted by a stepping motor.

The first fan shaft 133 and the second fan shaft 133 are each provided with a slip-ring (not shown).

According to the present invention, since a fan can be operated at a higher speed than a conventional fan-tilt system, in driving a device to be driven, such as a camera or a laser, There is an advantage that it is possible to easily track even an object moving at a high speed.
