DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a view illustrating a case where a ventilation system according to an embodiment of the present invention is installed in a front room of a ventilation path, and FIGS. 2 and 3 show a configuration of a ventilation system according to an embodiment of the present invention A block diagram and an example thereof.

First, referring to Fig. 1, the smoke inducing apparatus 100 according to the present embodiment is provided independently of an auxiliary chamber 1 (an entire chamber) of the evacuation route 3 such as a staircase. That is, when the smoke generated in the fire of the smoke inducing apparatus 100 flows into the ancillary room 1, the air is introduced into the ancillary room 1 by sensing the air and the air pressure (positive pressure) The smoke inducing apparatus 100 according to the present embodiment is installed in the air passage between the escape path 3 and the subsidiary room 1 such as a staircase to control the air flow in the two spaces, Air is introduced into the subsidiary chamber 1 and the positive pressure in the subsidiary chamber 1 is regulated. According to the present embodiment, each of the subsidiary chambers 1 is provided with the respective smoke-inducing apparatuses 100, and each of the smoke-inducing apparatuses 100 is connected to the connected And the air in the evacuation furnace 3 is used for positive pressure. In other words, the existing ventilation system causes unnecessary facilities to operate when all the ventilation damper and fan installed inside the building are operated when a fire occurs in a specific area, and it is difficult to maintain the required wind pressure in a specific area Do. In contrast, the stand-alone type smoke-inducing apparatus 100 according to the present embodiment is installed independently in each of the front rooms and is operated independently, so that energy can be used more efficiently, and even if one of them fails, to be.

Referring to FIGS. 2 and 3 showing a configuration and an example of the installation of the ventilation system 100, the ventilation system 100 according to the present embodiment includes an air supply fan 10, a pressure detection sensor 20, a smoke sensor 30, a short range wireless communication module 40, and a control module 50 (not shown in FIG. 3).

The smoke sensor 30 is a means for detecting smoke introduced into the entire room, and various smoke detection systems such as an optical smoke detection system using a method in which light is reflected by smoke introduced into the interior are currently used Those skilled in the art will appreciate that the smoke detection method will not be described in further detail.

The air supply fan 10 is for introducing the air of the escape route (emergency staircase or the like) into the subsidiary room, and corresponds to a passage formed on the wall between the subsidiary room and the escape route (for example, a hole passing through the middle wall of two spaces) (For example, to be connected to an air duct connected to the passage or passage), and air in the evacuation passage is introduced into the supporting chamber through the passage.

The pressure sensing sensor 20 is a sensing means for measuring the air pressure in the antechamber.

The control module 50 performs overall control of each component, and the control method thereof will be described in detail.

FIG. 4 is a flowchart showing a ventilation process of the ventilation system according to an embodiment of the present invention.

Referring to FIG. 4, when the smoke generated by a fire flows into the antechamber, the smoke detecting apparatus 100 detects smoke introduced by the smoke sensor 30 (S10).

When smoke is detected or smoke exceeding a preset threshold value is detected, the air supply fan 10 is operated to flow into the air roll attachment chamber in the escape path to increase the positive pressure (S20). That is, according to an example, when the value measured by the smoke sensor 30 is equal to or greater than a predetermined threshold value (a predetermined value that can be recognized as a fire occurrence), the air supply fan 10 is operated.

When the air supply fan 10 is operated, the control module controls the air supply fan 10 so that the air pressure measured by the pressure detection sensor 20 maintains a predetermined positive pressure range (S30). The predetermined positive pressure range may be a predetermined value range or may be a comparison value with the hall room (for example, a positive pressure of at least 40 Pa or more relative to the hall). In this case, And receives information on the positive pressure of the corridor by wire or wireless communication with the positive pressure measuring means provided in the hall. Hereinafter, a case in which the default positive pressure range set in advance is used will be mainly described.

Referring to FIGS. 2 and 3 again, the ventilation device includes a short-range wireless communication module 40 for performing short-range wireless communication such as bluetooth, zigbee, etc., and uses a short-range wireless communication module 40 And wirelessly communicates with the peripheral device.

For example, as shown in FIG. 4, when the smoke detection function (function of increasing the positive pressure in the subsidiary room) is performed by detecting the smoke, the smoke detection apparatus transmits a fire occurrence signal through wireless communication so that the peripheral, do. The other smoke-free device receiving the fire occurrence signal recognizes that a fire has occurred in the vicinity even if the smoke detection device itself can not detect the smoke, so that the smoke-free function can be performed. According to an example, the smoke inducing apparatus that receives the fire occurrence signal may perform only a certain level (for example, 80%, etc.) without driving the smoke-inducing function 100% And this will be described in detail later.

Here, according to an example, the smoke inducing apparatus may transmit a fire occurrence signal in a broadcasting manner, or may transmit and receive a bidirectional communication method in which a signal is transmitted and received with a preset other smoke inducing apparatus. Hereinafter, the broadcasting method will be described mainly for convenience of description, but it will be apparent to those skilled in the art that a bidirectional communication method can be similarly implemented.

Hereinafter, the radio communication with the other smokestack devices and the control process using the same will be described.

5 and 6 are a flowchart and an exemplary diagram illustrating a process of performing smoke control by communication with another smoke control apparatus according to an embodiment of the present invention.

Referring to FIG. 5, when the smoke generating device receives a fire occurrence signal from the other smoke detecting device (S510), it checks whether the other smoke detecting device that transmitted the fire occurrence signal is a neighboring peripheral device (S520). The reason for this is to avoid the unnecessary function of ventilation because the location of the fire is far from the periphery. To this end, the smoke inducing apparatus for transmitting the fire occurrence signal transmits identification information (for example, an ID such as a serial number or an IP address (or a MAC address) for communication) The smokestack device that has received the fire occurrence signal can identify the smokestack device that transmitted the signal (i.e., the smokestack that senses the smoke caused by the fire).

If it is determined that the apparatus is not the peripheral smoking apparatus, the standby mode in which the air supply fan 10 is not operated is maintained (S540).

Otherwise, if the peripheral smokestack device is confirmed, the air supply fan 10 is controlled according to the driving ratio corresponding to the preset information (S530). 6, when the first smoke-inducing device 100-1 senses smoke and sends out a fire generation signal, the second smoke-inducing device 100-2, which is set as a peripheral smokestack, 3 smoke-inducing device 100-3 confirms the received fire occurrence signal and operates the air supply fan 10 at a preset drive ratio for each. As shown in the figure, the first smoothing device 100-1 controls the air supply fan 10 so that the positive pressure range is 100% (for example, the positive pressure is maintained at 100), and the second smoke The apparatus 100-2 is set to a positive pressure range of 60% (for example, the positive pressure is set to 55) so that the apparatus 100-2 satisfies the positive pressure range of 80% (for example, the positive pressure is maintained at 70) Maintenance) is satisfied. In the above example, the drive ratio is adjusted to the positive pressure range. However, according to another example, the drive ratio (supply amount per hour) of the air supply fan 10 may be varied depending on the drive ratio.

In other words, when a fire generation signal is received from the surrounding other smokestack device, each smokestack controls the air supply fan 10 in accordance with a preset drive ratio so as to correspond to the smokestack. Therefore, each of the smoke-inducing devices can be selected at various ratios in adjacent rooms by using wireless communication with each other to generate required wind pressure, so that the positive pressure can be quickly maintained in an actually required area.

As shown in FIG. 6, in the case of the smoke inducing apparatus installed at a higher position than the smoke inducing apparatus which senses the smoke, the probability of the fire spreading is high, so that a higher driving ratio may be set.

According to another example, the smoke-inducing device may perform a failure checking function to check whether a failure has occurred periodically with other smoke-free devices by using the provided short-range wireless communication function.

FIG. 7 is a flowchart illustrating an inspection process by communication with another smoke-free apparatus according to an embodiment of the present invention.

Referring to FIG. 7, the smoke inducing apparatus performs communication for checking to confirm normal operation with the surrounding smoke generating apparatus at regular intervals (for example, 200 time intervals, etc.) (S710).

In step S720, it is checked whether there is a fault in the surrounding smoke inducing apparatus. For example, a method may be used in which, when the other smokestack device that is preset in the inspection period for performing the check does not transmit the check signal, the smokestack device is recognized as malfunctioning. Alternatively, each of the smoke-inducing devices may perform a self-check to check whether the pressure sensor 20 is operating properly by operating the air supply fan 10 during an inspection period, May be used.

If it is determined that there is no failure, the next cycle is counted to perform the next check function (S740).

If there is another smokestack device judged to be malfunctioning, the manager outputs a malfunction notification so as to recognize the malfunctioning smokestack device (S730).

According to the example, although not shown in the drawings, the smoke induction apparatus according to the present embodiment further includes a failure notification module that outputs a failure signal in a sound or display manner. That is, the control module periodically performs check communication for confirming a failure with other peripheral devices in the vicinity using the short-range wireless communication module 40, and when the check communication result is determined to be a failure, I will.

For example, if the failure notification module is a speaker, it is possible to output a message [failure occurred in the smoke inducing device of the OO layer supporting room]. If the failure display module has a display screen, the above message can be output to the screen . Or a plurality of lamps capable of identifying each peripheral device so that a lamp corresponding to the malfunctioning ventilation device is lit so that the manager can identify the malfunctioning device that has failed. In the case of using a lamp, a red lamp (indicating failure of the lower-layer smokestack) is displayed on the smokestack on the 11th floor, and a blue lamp (on the 9th- Indicating that the device has failed).

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
