FIGS. 10 and 11 are the second exploded views of a fire sensing unit of the present invention according to an embodiment of the present invention.

[0050] According to of the present invention, as shown in FIG. 1, individual real-time fire sensing monitoring system for fire compartments in building using rechargeable sensor around a penetration part monitors the size and spread rate of fire by compartment area as well as the origin of fire in a building in real time on the basis of profiling about whether fire occurs in a building.

[0051] The existing fire detection sensors installed on a ceiling of a living room, a room or an office in a building 1 only detect fire in a certain space sensing gas from fire. According to the existing skills, it seems to be advanced that an outbreak of fire alarms a central control system and fire information is automatically or semiautomatically transmitted to external agencies such as a fire station, but there has been a problem that installations in building makes limit in space and it is hard to detect a fire flow in one space.

[0052] According to the present invention, in order to solve the existing problems mentioned above, the inside of a building 1 is divided into designated conceptualized areas, which is divided into compartment areas(Zn).

[0053] The compartment area(Zn) is not the same as simply a concept of a room or a wall inside a room in a building 1.

[0054] As shown in FIG. 2, a compartment area(Zn) can be set up for one conceptualized compartment combining several rooms and one room can be divided into conceptualized compartments.

[0055] A compartment area(Zn) is divided by a partition wall 10 as described below, which does not have to be a bearing wall, but which should function as a firewall.

[0056] For this purpose, the present invention comprises a fire resistant sealing unit 100, a fire sensing unit 200 and a control server 2.

[0057] As shown FIG. 3, the fire resistant sealing unit 100 locates near a penetration part penetrating the partition wall 10 inside a building 1. More specifically, as shown in FIG. 6, the penetration pipe 11 penetrates the penetration part of the partition wall 10 and the fire-resistant sealing unit 100 is installed near respectively one side and the other side, covering the outer circumferential surface of a penetration pipe 11.

[0058] It is safe that a penetration pipe 11 without fire resistant is melted and burnt down by heat from fire.

[0059] If the penetration pipe 11 is melted by heat from fire, an inner part of the penetration pipe 11 is exposed causing a penetration part of the partition wall 10 to be exposed as it is.

[0060] The fire-resistant sealing unit 100 covering an outer circumferential surface of the penetration pipe 11 seals and fills an inner part of the penetration pipe 11 or the penetration part expanded and melted by heat from fire.

[0061] Because the fire resistant sealing unit 100 expanded by heat from fire is composed of heat-resistant materials from fire, expands toward an inner circumferential surface and seals a penetration part of the partition wall 10, it functions not to spread a gas from a side of the partition wall 10 to another side by the partition wall 10.

[0062] It is desirable that the fire resistant sealing unit 100 should meet the present standards of Notice of Ministry of Land, Infrastructure and Transport 2016-416.

[0063] According to the present invention, as shown in FIG. 3, the fire sensing unit 200 detects an outbreak of fire in compartment areas(Zn) locating near the fire resistant sealing unit 100.

[0064] As shown in FIG. 3, the fire sensing unit 200 is placed at both sides in pairs of a partition wall 10 near the fire resistant sealing unit 100, firstly senses an outbreak of fire in compartment areas(Zn) and at the same time the fire resistant sealing unit 100 proceeds to seal from hear of fire.

[0065] For example, fire gas at Z1 of FIG. 4 can spread to adjacent Z2 and the gas spreads through a penetration part of a partition wall dividing Z1 and Z2. Therefore, a fire sensing unit 200 first senses adjacent areas of Z1 at Z2 compartment area after it detects the fire from Z1 at Z1. The fire sensing unit 200 placed near at both sides of a penetration part of the partition wall 10 by compartment area detects spreading from which compartment area to which compartment area and spreading speed and path of fire according to action of the fire resistant sealing unit 100 as shown in FIG. 5.

[0066] Therefore, the control server 2 can be placed inside or outside of a building 1.

[0067] As described above, the control server 2 divides the inside of a building 1 into designated conceptualized areas, corresponding to compartment area(Zn) as said above.

[0068] The control server 2 continuously detects fire occurrence information of the fire sensing unit 200 arranged for compartment area in real time, but as shown in FIG. 5, depending on the mechanism of the fire resistant sealing unit 100 of the penetrating part dividing the partition wall 10, it can definitely detect how much the fire spreads. That is, for example, after only a portion of the gas is generated from one compartment area and spread to the other compartment area if a supply of the gas is cut off due to mechanism of the fire-resistant sealing unit 100, the fire detection in the other compartment, that is, gas detection is stopped, only a certain degree of spreading of the gas is recognized, and it can be recognized that spreading has not occurred until the actual fire.

[0069] The control server 2 estimates fire occurrence information of a fire sensing unit 200 through continuous fire gas detection. It can check whether a fire gas blocking of the fire resistant sealing unit 100 stops spreading after only a fire gas is partially spread in a specific compartment area, or whether mechanism of the fire-resistant sealing unit 100 is insufficient, or mechanism of the fire resistant sealing unit 100 alone is insufficient to prevent the spread of fire after fire gas is spread.

[0070] The control server 2 estimates fire vector information. As described above, the fire vector information includes direction and speed at which the fire spread from one compartment area Z1 to the other division area Z2, and a fact about whether or not the fire actually occurred.

[0071] According to the present invention, as shown in FIGS. 6 and 7, a fire-resistant sealing unit 100 comprises the outer ring part 110 and the fire-resistant filling part 120.

[0072] As shown in FIG. 7, the outer ring part 110 is placed apart to surround an outer circumferential surface from an outer circumferential surface of the penetration pipe 11.

[0073] The outer ring part 110 is made of a circular band or chain, or an assembly of several hinge-connected structures, and the inner circumferential surface described below comprises the fire-resistant filling part 120.

[0074] The fire-resistant filling part 120 is placed at between an inner circumferential surface of the outer ring part 110 and an outer circumferential surface of the penetration pipe 11, and inside of the penetration pipe 11 inwardly expanded and melted by heat of fire, that is, one surface or the other surface of the penetration part is sealed with fire-resistant.

[0075] The outer ring part 110 having the fire-resistant filling part 120 on the inner circumferential surface resists an outward expansion force of the fire-resistant filling part 120 making the fire-resistant filling part 120 expand inwardly.

[0076] The fire sensing unit 200 comprises a housing part 201, a light-emitting plate part 210, and a photoelectric plate part 220.

[0077] As shown in FIG. 8, the housing part 201 forms an external body of the fire sensing unit 200, and gas generated from fire through a gas penetration part 201h provided in the external body is inpoured.

[0078] The light-emitting plate part 210 is provided in the housing part 201 and emits light through applied electric power.

[0079] The light-emitting plate part 210 transfers an energy of emitted light to the photoelectric plate part 220 as described below.

[0080] Thereafter, the photoelectric plate part 220 is placed to face the light-emitting plate part 210 and receives light emitted from the light emitting plate part 210.

[0081] As shown in FIG. 9, the photoelectric plate part 220 generates a change in current through a change in the amount of light received due to the fire gas flowing into the housing part 201, and through this, gas detection of fire is made. As a result, information about the occurrence of a fire is recognized.

[0082] The light emitting part 210 sequentially generates a lane of emitted light, and through this, each light reception level can be recognized differently depending on a power generation position of the photoelectric plate part 220 that receives and generates light. Through this, it is possible to sense concentration of fire gas and speed of spreading even within one fire sensing unit 200.

[0083] As shown in FIG. 10, as another embodiment of the fire sensing unit 200, the fire sensing unit 200 comprises a housing part 201, an ionizing part 230 and a conduction part 240.

[0084] As described above, the housing part 201 forms an external body of a fire sensing unit 200, and inpours fire gas generated during a fire through a gas penetration part 201h provided in the external body.

[0085] The ionizing part 230 is provided in the housing part 201 and generates ions through applied power.

[0086] Ions generated by the ionizing part 230 flow into the conduction part 240, and current flows through ions reaching the conduction part 240.

[0087] That is, the conduction part 240 is spaced apart from the ionizing part 230 receives ions generated from the ionizing part 230 to generate a current flow from the ionizing part 230.

[0088] As shown in FIG. 11, the conduction part 240 generates a change in current through a change in the amount of light received due to fire gas flowing into the housing part 201, thereby sensing information on the occurrence of fire.

[0089] As shown in FIG. 1, the control server 2 detects fire occurrence information and fire vector information for each compartment area, and transmits it to the external server 4, for example, a fire station, and through this, fire occurrence leads to a computational response.

[0090] The scope of the present disclosure should be determined by listed items, and the brackets of claims are listed not for optional limit but for clear elements, and contents of brackets should be understood as essential elements.
