The smoke sensing unit 12 may be an ion-type sensor that senses the combustion-generating particles as a change in the ion current, or an optical sensor that senses a change in the light flux by smoke.

Further, a known technique using a thermal sensor responsive to ambient temperature changes can be applied to the heat sensing unit 14. [

The blocking portion 20 is embedded in the ceiling C in the building and is moved by the shutter operating portion 30 to close the passageway so as to prevent heat or smoke from spreading due to the fire. The passage may be a kind of passage formed by the ceiling C in the building, the first inner wall W1, and the second inner wall W2. The blocking portion 20 can prevent the fire or smoke from being moved to the other side due to a fire generated at one side by closing the traveling passage.

In addition, the blocking portion 20 may be formed to be transparent so as to secure a field of view from one side to the other side, but it may be opaque.

 The shutter operation unit 30 may lower the shutoff unit 20 based on a detection signal applied from the fire sensing unit 10. [ The shutter actuating part 30 may be a kind of motor driven by a power source so that the shutting part 20 is pulled out of the ceiling C while connected to the shutting part 20 so as to be lowered So that the cut-off portion 20 is wound up so as to move upwards toward the ceiling (C).

The position sensing unit 40 may be disposed on the movement path of the blocking unit 20 to detect the position of the blocking unit 20. The movement path of the blocking portion 20 means a path of the moving path of the blocking portion 20 moved along the first inner wall W1 and the second inner wall W2 while being embedded in the ceiling C And the position sensing unit 40 may be installed on at least one of the first inner wall W1 and the second inner wall W2 to sense the position of the blocking unit 20.

The shutter operation unit 30 may be controlled to move up or down the blocking unit 20 according to the position of the blocking unit 20 sensed by the position sensing unit 40, The upward and downward movements of the blocking portion 20 along the portion 40 will be described later.

FIGS. 3 to 6 are schematic views for explaining the operation of the blocking unit of the fire control shutter control system according to the embodiment of the present invention, and each of FIGS. 3 to 7 is a block diagram of a control unit, a shutter operating unit, Please refer to the drawings for the specific mechanism to explain the negative mechanism.

Referring to FIG. 3, the controller 50 may control the first operation of the shutter operation unit 30 according to the smoke detection information sensed by the smoke sensing unit 12, The second operation of the shutter operation unit 30 can be controlled according to the thermal sensed information sensed by the second sensor 14.

3 (a), the first operation of the shutter actuating part 30 is an operation of moving downward to a position of the first height H1 of the blocking part 20, that is, Wherein the first height H1 means a height from the bottom surface B toward the ceiling C and the first height H1 is a height from the bottom surface B to the ceiling C, C). ≪ / RTI >

Specifically, when the height from the bottom surface B to the ceiling C is L and the first height H1 is H1, in accordance with the first operation of the shutter operating portion 30, (20) can move down by L - H1.

When the shutter 20 is lowered by L - H1 by the first operation of the shutter operating portion 30, the smoke caused by the fire can not be blocked by the path along the ceiling C .

3 (b), the second operation of the shutter actuating part 30 is a downward movement from the first height H1 of the blocking part 20 to the second height H2 Wherein the second height H2 is a height from the bottom surface B toward the ceiling C and the second height H2 is a height from the first height H1 ).

Specifically, when the second height H2 is H2, the blocking unit 20 can move down by H1 - H2 according to the second operation of the shutter operating unit 30. [

When the shutoff part 20 is lowered by H1 - H2 by the second operation of the shutter operating part 30, the smoke, fire or fire due to the fire is prevented from diffusing, Can be prevented.

In the drawings, the second height H2 is shown as being a certain distance away from the bottom surface B, but this is according to one embodiment, and the second height H2 may be zero, The portion 20 may be in contact with the bottom surface B. [

The position sensing unit 40 includes a first position sensing unit 42 positioned at the first height H1 and a second position sensing unit 44 positioned at the second height H2. can do.

The first position sensing unit 42 senses the position of the blocking unit 20 according to the proximity distance to the blocking unit 20. At this time, the first position sensing unit 42 contacts the blocking unit 20, It is possible to detect the blocking portion 20.

The first position sensing unit 42 may be disposed at a position where the blocking unit 20 is located at a position lower than the first height H1 and lower than the first height H1, Can be detected. That is, when the blocking unit 20 is detected by the first position sensing unit 42, the blocking unit 20 may be located at a height less than or equal to the first height H1.

The second position sensing unit 44 may sense the position of the cutoff unit 20 according to the proximity of the cutoff unit 20 and may be in contact with or in contact with the cutoff unit 20 It is possible to detect the blocking portion 20.

The second position sensing unit 44 may be disposed at a position where the blocking unit 20 is located at a position lower than the second height H2 as well as the second height H2, Can be detected. That is, when the breaker 20 is detected by the second position sensing unit 44, the breaker 20 may be located at a height less than or equal to the second height H2.

The control unit 50 determines that the blocking unit 20 is seated on the bottom surface B when the blocking unit 20 is sensed by the second position sensing unit 44, The control of the control unit 30 can be terminated.

Here, the second position sensing unit 44 may be installed on the bottom surface B to sense the position of the cut-off unit 20 in accordance with the contact with the lower end of the cut-off unit 20. Or the first inner wall W1 or the second inner wall W2 adjacent to the bottom surface B to detect the position of the blocking portion 20 in accordance with the contact with the blocking portion 20, The control unit 50 terminates the operation of the shutter operating unit 30 when the second position sensing unit 44 determines that the blocking unit 20 is seated on the bottom surface B, The movement of the blocking portion 20 can be blocked.

Although the second position sensing unit 44 is shown as being located on the first inner wall W1 on the bottom surface B in the figure, it is a diagram according to an embodiment of the present invention, The portion 44 may be located on the floor B side.

4, the blocking unit 20 according to an embodiment of the present invention may be configured such that the shutter 20 is rotated at a speed from the ceiling C to the first height H1 in accordance with the first operation of the shutter operating unit 30. [ Can be gradually increased.

Specifically, when the smoke sensing unit 12 senses smoke, the controller 50 receives a sensing signal from the smoke sensing unit 12 to drive the shutter actuating unit 30, At this time, it is possible to control the speed V1 of the first operation of the shutter operating part 30 to gradually increase.

Here, the controller 50 may cause the first operation of the shutter actuating part 30 to freely move the blocking part 20. That is, the lowering motion of the blocking portion 20 to the first height H1 according to the first operation may be a lowering motion of a height that does not disturb the user moving the passage. For example, the first height H1 may be 2 m or more, and thus the downward movement of the blocking portion 20 to the first height H1 may not cause inconvenience to the movement of the passageway of the user even if it falls freely .

The blocking unit 20 may be configured to perform a descent motion in which the speed V2 is constant from the first height H1 to the second height H2 according to the second operation of the shutter operating unit 30. [ .

Specifically, when the heat sensing unit 14 senses heat, the control unit 50 receives a sensing signal from the thermal sensing unit 14 to drive the shutter operating unit 30. At this time, The speed of the second operation of the shutter operating portion 30 can be controlled to be constant.

That is, since the lowering motion of the blocking portion 20 from the first height H1 to the second height H2 according to the second operation may interfere with the user moving in the passage, The lowering motion can be performed at a constant speed so that the user is not injured by the blocking unit 20 that is operated by the user.

Alternatively, the control unit 50 may control the speed V3 of the second operation of the shutter operation unit 30 to be gradually decreased, which may provide a time margin for moving the passage to the user moving the passage So that the life structure can be more stably progressed.

When the control unit 50 receives the detection signal at the same time by the smoke sensing unit 12 and the thermal sensation unit 14, the first operation and the second operation of the shutter operation unit 30 are sequentially The shutter operation unit 30 can be controlled to proceed to the shutter operation unit 30.

5 and 6, the position sensing unit 40 according to an exemplary embodiment of the present invention includes a position sensing unit 40 disposed at a third height H3 that is lower than the first height H1 and higher than the second height H2 The third position sensing unit 46 may further include a fourth position sensing unit 48 positioned at a fourth height H4 that is lower than the first height H1 and higher than the third height H3 .

More specifically, if the position sensing unit 40 is arranged in the order of increasing height from the bottom surface B, the second position sensing unit 44, the third position sensing unit 46, the fourth position sensing unit 48, and the first position sensing unit 42.

Since the height of the blocking portion 20 is sensed by the first position sensing portion 42 to the fourth position sensing portion 48, May be sensed by the position sensing units 40. [0033] FIG.

The control unit 50 determines whether the blocking unit 20 is between the fourth height H4 and the third height H3 after passing the fourth height H4 at the first falling velocity V4, (See FIG. 5 (b)), it is determined that the blocking portion 20 is located at the fourth height H4 through the shutter operating portion 30, And the shutter operation unit 30 can be controlled such that the lowering motion of the blocking unit 20 is started when the blocking unit 20 reaches the fourth height H4 .

The shielding part 20 is moved from the ceiling C to the first height H by referring to the positional relationship of the shielding part 20 moved by the shutter operating part 30, (See Fig. 5 (a)) from the first height H1 to the fourth height H4, and the descending speed at this time may be the first descending speed V4. 5 (b)), if the blocking unit 20 does not appear after a time required to be positioned at the third height H3 based on the first falling speed V4, The blocking portion 20 can be lifted up to the fourth height H4 (see Fig. 6 (a)).

This may be the case where a user moving a specific object or passage is located between the fourth height H4 and the third height H3 and the movement of the blocking portion 20 is limited. The blocking portion 20 can perform the above-described upward movement to provide a space and a time at which an element whose movement restriction of the blocking portion 20 is removed is removed.

The control unit 50 may control the shutter operation unit 30 such that the upward motion is realized when it is determined that the lowering motion of the blocking unit 20 is restricted.

When the blocking unit 20 reaches the fourth height H4 after the blocking unit 20 moves upward, the controller 50 controls the second lowering speed V6 that is faster than the first lowering speed V4, The shutter operation unit 30 can be controlled to move downward.

This is because, in order to reduce the temporal loss due to the upward movement, that is, to minimize diffusion of the smoke or diffusion of heat due to the upward movement, the second falling speed V6, which is faster than the first falling speed V4, Thereby causing the portion 20 to move.

7 and 8, the blocking part 20 according to an embodiment of the present invention includes a first inner wall W1 and a second inner wall W2 connected to the ceiling C and the ceiling C, Is moved to close or open the passage formed by the valve

And the fourth position sensing unit 48 includes a fourth position sensing unit 481 installed at the first inner wall W1 and a fourth position sensing unit 482 installed at the second inner wall W2 And a 4-2 position sensing unit 482. [

The control unit 50 includes a position sensing unit 40 located at the first inner wall W1, that is, a 1-1 position sensing unit 421, a 2-1 position sensing unit 441, The positions of the blocking portions 20 sensed by the position sensing portion 461 and the 4-1 position sensing portion 481 and the positions of the position sensing portion 40 located at the second inner wall W2, The cutoff unit 20 sensed by the 2 position sensing unit 422, the 2-2 position sensing unit 442, the 3-2 position sensing unit 462 and the 4-2 position sensing unit 482, The position sensing unit 40 positioned at the first inner wall W1 and the position sensing unit 40 positioned at the second inner wall W2 are not corresponding to each other, It is possible to control the shutter operating part 30 to move the blocking part 20 upward to the position of the position sensing part 40 at the highest position.

Specifically, for example, the blocking portion 20 is lowered and sensed by the second-1 position sensing portion 441 located on the first inner wall W1, but the second inner wall (See FIG. 7 (b)) of the blocking unit 20, the second-second position sensing unit 442 and the third-second position sensing unit 462 located in the first to n- That is, since it is determined that the movement of the blocking portion 20 adjacent to the second inner wall W2 is restricted by the specific object or the passer, the blocking portion 20 breaks the specific object, The blocking portion 20 may raise the blocking portion 20 to prevent the second sensing portion 40 from being in contact with the position sensing portion 40 located on the first inner wall W1. 2 position sensing unit 442 and the 3-2 position sensing unit 462 located at a higher position among the 3-2 position sensing unit 462 8 may be referred).

For example, various cases may occur depending on the positional relationship of the position sensing unit 40 sensed by the blocking unit 20, which can be sufficiently inferred based on the above example, do.

The second blocking portion 23 may be formed of a metal.

The first inner wall W1 of the building connected from the ceiling C and the ceiling C by the first blocking portion 21, the second blocking portion 22 and the second blocking portion 23, The passage formed by the second inner wall W2 may be closed or opened.

Specifically, the first blocking portion 21, the second blocking portion 22, and the second blocking portion 23 may each close or open a certain portion of the passage.

For example, the first blocking portion 21 is disposed adjacent to the first inner wall W1, the second blocking portion 23 is disposed adjacent to the second inner wall W2, 2 blocking portion 22 may be disposed between the first blocking portion 21 and the second blocking portion 23. [

The blocking portions 20 may have the same size, but are not limited thereto.

The control unit 50 may control the lowering speed V7 of the first blocking unit 21, the lowering speed V8 of the second blocking unit 22 and the lowering speed V8 of the third blocking unit 23, (V9) are different from each other.

For example, when the first blocking portion 21, the second blocking portion 22, and the third blocking portion 23 start the descending motion at the same time, When the second blocking portion 22 descends at a faster speed than the blocking portion 22 and the third blocking portion 23 and the second blocking portion 22 descends at a faster speed than the third blocking portion 23, The first blocking portion 21, the second blocking portion 22, and the third blocking portion 23 may be in contact with the bottom surface B sequentially.

A light emitting body L that emits light by power may be formed at the lower ends of the first blocking unit 21, the second blocking unit 22, and the third blocking unit 23 (C)).

That is, when the lower end of the blocking part 20 comes into contact with the bottom surface B, the passage is closed. Therefore, when the degree of the movement of the lower end is light emitted by the light emitting body L, A passer or the like passing through the passage can intuitively recognize the position of the blocking portion 20. [

A known technique for emitting light can be applied to the light emitting unit L, which is located at the lower end of the shield 20.
