Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation system,

The present invention relates to the rehabilitation and ventilation of pipelines such as water supply and sewerage, and more specifically, to improve the efficiency in the process of the inner wall of the old pipe of a pipe having a large diameter, and to improve safety in case of occurrence of various safety problems The present invention relates to an interlocking type in-pipe combined ventilation system.

Generally, a pipe for forming a water supply and drain pipe is usually a cast iron pipe, a steel pipe, a Hume pipe, a PE pipe, or the like. Therefore, if such a water supply and drainage pipe is used for a certain period of time, leakage of water such as rust may occur due to foreign substances such as rust on the inner and outer sides of the water supply and sewage pipe, leakage of water may occur due to corrosion or relaxation of the joint portion of the pipe, There is a problem such as being damaged.

Accordingly, the water supply and drainage pipes used for a certain period of time should be replaced with new ones. When replacing such water supply and drainage pipes, the water supply and drainage pipes normally buried in the underground are removed and new water supply and drainage pipes are buried again.

However, most of the water supply and drainage ducts are buried in the roads or the lower part of the building. In order to newly install the water supply and sewerage pipes, large-scale excavation works must be carried out. And so on.

Recently, instead of replacing the water supply and sewer pipe, epoxy resin paint is sprayed on the inner wall of the old section to form a coating film, or a soft tube is installed on the inner wall of the old pipe to rejuvenate the old pipe Rehabilitation methods are widely used.

Korean Patent Publication No. 10-0949956 discloses a hardening rehabilitation method in a water supply and drainage pipe using a conventional air tube, and FIG. 1 is a schematic view of the same.

Specifically, the repairing tube 1 is inserted into the pipe in the process of regenerating the old water supply and sewage pipe. The repairing tube 1 is internally provided with an air tube 3 for traction, A hose 2 is provided. Accordingly, the flow rate of the steam supplied through the steam hose is improved to improve the efficiency of the construction work.

However, this method can be applied to the construction of small-scale urban water pipes, and it is practically applied to the construction of large-scale waterworks pipes supplied from the water source to each regional unit considering the size of equipment, cost and energy consumption. impossible.

Furthermore, since the caulking enamel or the inner coating material applied inside the aged water pipe serves as a source of contamination of the water pipe due to corrosion, there is a need to remove it, and in the past, there has been no method capable of practically treating it on a large scale.

In the case of a wide-area water supply pipe sent from a large-scale water source such as the Han River or the Geum River, most of the water pipe is aged and the internal corrosion is progressing considerably. Accordingly, a leakage is continuously generated. However, it was difficult to implement it as a national project, unlike the case of urban waterworks, because excessive replacement costs were required.

The removal of the collet inside the existing water supply pipe and the application of the paint are inevitable as manpower, but this case also has some problems.

In the case of a wide-area water supply pipe, its diameter ranges from 1m to 4m and its length is in the range of tens to hundreds of kilometers. For example, in the Geum River area, the wide-area water supply pipe is 1.1 to 1.5 meters in diameter and is known to be several tens of kilometers in length.

However, when the manpower is directly injected and rehabilitation work is performed, there is a risk of suffocation because the supply of oxygen for the survival is not smooth in the pipeline. Especially, when the fire occurs, the toxic gas is inhaled directly. There is a continuing problem.

Also, since the pipeline buried in the ground is considerably long, it is difficult to recognize and cope with it from outside.

The present invention has been conceived in order to solve the above problems, and it is an object of the present invention to provide an interlocking type indoor ventilation system capable of securing safety by avoiding human casualties and allowing early response when working inside a pipeline such as a large- And to provide the above objects.

The air supply unit includes an air supply first damper 1911 for opening and closing a path of the air supply chamber and the air supply duct, an air supply second damper 1912 for opening and closing the communication between the air supply chamber and the air supply emergency portion, And an air supply third damper 1913 for opening and closing the external communication.

Wherein the exhaust unit includes an exhaust body portion for exhausting the air inside the duct to the outside, an exhaust chamber portion interposed between the exhaust body portion and the exhaust duct, It is preferable to form the switching air supply flow path so as to flow into the inside of the pipe.

In one embodiment, the composite control unit can determine the escape direction (gamma) in a direction in which the air supply is supplied when the fire generation point is located at the rear end of the operation position with respect to the traveling direction of the air supply channel.

In another embodiment, the hybrid control unit determines the direction of evacuation in the direction of advance of the air supply and switches the direction of flow in the air supply unit and the exhaust unit when the fire generation point is located before the working position with respect to the traveling direction of the air supply channel .

The survival module is connected to each connection point of the connection line and transmits a sensing signal to any one of the oxygen sensor unit 431, the temperature sensor unit 436, the humidity sensor unit 437, So as to judge the fire occurrence and the evacuation direction, and to feedback control the temperature and humidity of the air to be harmonized in the exhaust unit.

The present invention is basically based on an environment in which a large amount of manpower is put into operation such as a water pipe and a predetermined rehabilitation work is performed. However, in addition to various types of pipes, a predetermined space A space such as a tunnel or a parking lot that can be formed should be understood as being included in the concept of the duct described in the present invention.

In the process of rehabilitation, a part of the pipeline is cut from both sides, and the internal coating material is removed and recovered from the piping disposed therebetween, and the work is put in the process of rehabilitation by forming the surface after the surface treatment on the inner wall In the basic concept of the present invention, the air supply unit and the air discharge unit function to supply outside air in one direction for the survival of such attraction. Specific embodiments relating to the connection of the duct to the air supply unit and the exhaust unit will be described later.

According to the present invention, the combined control unit functions to control the flow of the air supply unit and the exhaust unit optimally so as to be able to survive in consideration of the location of the fire occurrence point and / or the attraction position inside the pipe, Explain it.

FIG. 2 is a block diagram for explaining a combined ventilating system of the present invention.

The pipeline 100 may be disposed in a manner buried in the ground, and the pipeline may include passages of a length longer than a width such as a tunnel or underpass.

A worker is input into the pipeline 100 to carry out the same operation as the regeneration process. When the outside air is not supplied because of the long length of the pipeline 100, there is a risk of suffocation due to the lack of oxygen of the operator, so that the air supply unit 1000 and the exhaust unit 2000 are disposed on one side and the other side, respectively, for survival .

In the drawings, the side on which the air supply unit 1000 is disposed is defined as one side and the side on which the air exhaust unit 2000 is disposed is defined as the other side.

The air supply unit 1000 purifies the outside air and adjusts the temperature and humidity so as to introduce the conditioned air into the inside of the pipeline 100. The exhaust unit 2000 purifies the air containing oxygen by exhausting air containing moisture from the outside And discharging it.

The air supply unit 1000 and the air exhaust unit 2000 can basically perform the following three functions.

First, the supply of outside air for the survival of a worker put in the pipeline 100 to carry out the regeneration process, and second, the dehumidification air for removing water in the pipe And third, the dust generated according to the process inside the pipe is classified as filtering to purge the air to be discharged to the outside air. Embodiments of the air supply unit 1000 and the exhaust unit 2000 for carrying out these basic functions will be described later.

In the present invention, in addition to this, the air supply unit 1000 and the exhaust unit 2000 switch the direction of the air to perform the fourth function for allowing the operator to survive and escape in the event of fire or pollution in the pipe .

In order to perform the first to third functions, the air supply unit 1000 feeds ambient air harmonized with the air supply flow path 311 to the pipeline 100, and the exhaust unit 2000 removes air from the inside of the exhaust flow path 321 It is inhaled, purified and discharged to the outside.

In order to prevent the toxic gas or the like from flowing in the direction of escape of the operator according to the point of occurrence of the fire or pollution inside the air supply unit 1000, And the other side allows the exhaust unit 2000 to switch the direction of flow to the switching supply and exhaust flow path 322. [

The air supply unit 1000 and the exhaust unit 2000 are connected to the composite control unit 200. The composite control unit 200 senses a state of the inside of the pipeline 100 and determines a predetermined flow operation condition, 1000) and the exhaust unit 2000 via a control line (not shown).

The hybrid control unit 200 may be connected to the connection unit 401 to monitor the inside of the conduit 100 and detect the occurrence of a fire, the location of a fire, and the position of an operator. The connecting line portion 401 may be a predetermined lead that is inserted into one side of the inside of the conduit 100 and the other side. The connection terminal unit 401 may include a power line for supplying power for performing a job to the inside of the pipeline 100. The connection terminal unit 401 may include a terminal for connection of a lamp or a socket at predetermined positions, can do. In this case, a power line communication method may be used to transmit / receive predetermined sensing signals and control commands to / from the respective positions of the hybrid control unit 200 and the connection line unit 401. However, it should be noted that the connection terminal unit 401 does not exclude wireless communication systems such as Wi-Fi and Zigbee communication.

The connection line unit 401 may include a survival module 400 at each location. The survival module 400 may include an intercom for communication with the outside such as the ground, a fire detection sensor, an operator's location confirmation module, Etc., and preferred embodiments thereof will be described later.

In the concept of the present invention, the composite control unit 200 receives a fire detection signal from the connection line unit 401 and alerts the administrator or the management server to the direction of the flow through the location of the fire point and the worker, The unit 1000 and the exhaust unit 2000 can control the flow in the pipe in the most effective direction for survival.

Since the distance between the air supply unit 1000 and the air exhaust unit 2000 can be arranged at a distance of 1 km or more, it is basically preferable that the composite control unit 200 is installed on the side of the air supply unit 1000, The combined control unit 200 may be separately provided in the air supply unit 1000 and the exhaust unit 2000 and may be individually or inter-operatively controlled for individual control under the condition that only the units of the air supply unit 1000 are operable.

Therefore, when the air supply unit 1000 and the air exhaust unit 2000 can be independently controlled and each of them can form an intake and discharge unit, the damage of the survival module 400 in the duct 100 Even if there is a disconnection of the connecting line portion 401, any one of them may be operated, and the above case may be applied so that it can function complementarily to enable an operator to survive. It is preferable that the connection line unit 401 is configured so that information can be transmitted from the survival module 400 in one direction even if a disconnection occurs at a certain point in the pipeline 100.

3 is a schematic view for explaining a preferred embodiment of the air supply unit and the air exhaust unit in the interlocking type in-pipe combined ventilation system of the present invention.

The air supply unit 1000 may be connected to one side of the duct 100 to form the air supply duct 311 and the switching exhaust duct 312. Such ducts may be formed by the air supply duct unit 3100 .

The air supply duct part 3100 may be formed in the form of an exhaust pipe connecting the discharge side of the air supply unit 1000 and the one end side of the pipeline 100. In consideration of the efficiency of the operator's input and flow, A door assembly (not shown) may be formed between the air supply duct 100 and the air supply duct portion 3100.

The air supply flow path 311 is indicated by a solid line so that air flows from one side of the pipeline 100 to the other side. The switching exhaust flow path 312 is indicated by a dashed line, and air, which flows from the other side of the pipeline, (1000).

In consideration of the switching of the air supply and exhaust, the air supply unit 1000 can be divided into the air supply unit and the air supply emergency unit, and an air supply chamber unit 1910, which forms a common flow passage, Can be intervened. An embodiment of the above-mentioned grade basic body portion will be described later.

The flow path of the grade basic body portion is formed as an air supply flow path 311 through the air supply chamber portion 1910 and extends into the pipeline 100. When it is necessary to switch the flow according to the situation inside the pipeline 100, And a switching exhaust passage 312 is formed in the reverse direction. The switching and exhausting flow path 312 communicates with the outside through the air supply chamber 1910 and the air supply and discharge unit 1920.

For this purpose, an air supply first damper 1911 may be formed on the air supply passage 311 side of the air supply chamber portion 1910. The first air supply damper 1911 functions to open and close the communication between the air supply chamber portion 1910 and the air supply flow path 311 and may block the inflow of air into the air supply flow path 311, To prevent the flow inside the conduit 100 from being formed. In some cases, the closing of the supply air flow path 311 can contribute to preventing the noxious gas from moving to the escape route when the operator escapes.

The air supply and discharge unit 1920 functions to connect the air supply chamber unit 1910 to the outside and a third air supply damper 1913 is interposed between the air supply chamber unit 1910 and the air supply unit 1920, Can be opened and closed. The air supply third damper 1913 is basically closed during operation of the air supply passage 311 and can be opened during operation of the switching exhaust passage 312.

The air supply chamber portion 1910 may be connected to the air supply emergency portion (not shown) and may be communicated by the air supply second damper 1912 when necessary for forming the switching air supply flow path 312, An air supply emergency fan portion 1930 may be disposed to provide a suction force for forming the switching exhaust flow path 312.

It goes without saying that the air supply emergency pan section 1930 may also be configured as a rotation direction control of the air blowing fan arranged in the basic element body as the case may be.

The operation of the air supply first damper 1911, the air supply second damper 1912, the air supply third damper 1913 and the air supply emergency pan section 1930 is performed in accordance with a control command of the hybrid control section 200, The composite controller 200 determines the formation of the flow in consideration of the optimum control of the position and the direction of the flow.

The exhaust unit 2000 may be connected to the other side of the duct 100 to form an exhaust passage 321 and a switching air supply passage 322. The passage may be formed by an exhaust duct portion 3200 .

The exhaust duct part 3200 may be in the form of an exhaust pipe connecting the inlet side of the exhaust unit 2000 and the other end side of the pipeline 100. In the same way as the air supply duct part 3100, A door assembly (not shown) may be formed between the door 3200 and the door 3200.

The exhaust air flow path 321 is indicated by a solid line so that air flows from one side of the pipeline 100 to the other side. The switching air supply flow path 322 is indicated by a dotted line, and the air sent out from the exhaust unit 2000 flows from one side So that it can be introduced into the air supply unit 1000.

The exhaust unit 2000 may also be divided into an exhaust body portion and an exhaust emergency portion, and an exhaust chamber portion 2910 forming a common flow passage may be interposed therebetween in consideration of the switching efficiency of the exhaust and the switching supply and exhaust. The flow path of the exhaust body part allows the exhaust flow path 321 to flow to the exhaust body part through the exhaust chamber part 2910. When it is necessary to switch the flow according to the situation inside the pipeline 100, A flow path 322 is formed. The switching air supply passage 322 is formed through the exhaust duct portion 3200 through the exhaust chamber portion 2910 from the exhaust emergency portion.

A first exhaust damper 2911 is formed on the side of the exhaust chamber 2910 connected to the exhaust duct portion 3200 to function to open and close the exhaust chamber portion 2910 and the exhaust duct portion 3200 . The flow of air from the exhaust passage 321 to the exhaust passage 321 can be blocked to prevent a flow in the passage 100 from being formed. In some cases, the closing of the supply air flow path 311 can contribute to preventing the noxious gas from moving to the escape route when the operator escapes.

The exhaust vent 2920 functions to connect the exhaust chamber 2910 to the outside and an exhaust third damper 2913 is interposed between the exhaust chamber 2910 and the exhaust vent 2920, Can be opened and closed.

The exhaust chamber portion 2910 is connected to the exhaust emergency portion and communicated through the exhaust second damper 2912 when necessary for forming the switching air supply flow path 322. An exhaust emergency pan portion 2930 is provided in the exhaust emergency portion So that it is possible to provide a blowing force for forming the switching air supply flow path 322. Needless to say, the exhaust emergency pan 2930 may be configured as a rotational direction control of the blower fan disposed in the exhaust body.

The operation of the exhaust first damper 2911, the exhaust second damper 2912, the exhaust third damper 2913 and the exhaust emergency pan 2930 is also performed in accordance with a control command of the hybrid control unit 200, In consideration of the optimal control of the position of the operator and the direction of the flow, the composite control unit 200 determines the formation of the flow. At this time, the composite control unit 200 operates the air supply unit 1000 and the exhaust unit 2000 in cooperation with each other, so that even in the case of a comparatively long water supply pipe, it is possible to smoothly form an air flow for survival, As shown in FIG.

FIG. 4 is a view showing a state in which the interlocking-type in-pipe combined ventilation system according to the present invention is installed in an old-age water supply pipe.

As shown in the figure, excavation of the ground and excision of the duct are performed at both ends of the duct 100 corresponding to a length required for a predetermined regeneration operation, thereby forming the air supply cutout portion 110 and the exhaust cutout portion 120 . The cut-off portions form a predetermined space, and a plug portion 3130 may be disposed at a portion facing the pipeline 100 where a rehabilitation operation is requested, in order to block the pipeline.

A door assembly 3200 is disposed on one side and the other side of the duct 100. The door assembly 3200 maintains the airtightness of the inside of the duct and air of which temperature and humidity are harmonized from the air supply unit 1000 flows into the duct assembly 3200, So that exhaust gas containing dust can be discharged to the exhaust unit 2000. To this end, the door assembly 3200 may be formed separately from a door, which is an entrance door, a duct for connection between the air supply unit 1000 and the exhaust unit 2000, and a connection site.

The door assembly 3200 at one side communicates with the air supply duct portion 3100 and extends upward, and the air supply unit 1000 is disposed at the distal end portion.

The air supply unit 1000 controls the temperature and humidity of the outside air to flow into the inside of the pipeline 100. The air supply unit 1000 supplies oxygen for the survival of the inside of the pipeline 100 and ventilation for removing dust It should be noted that it performs the function to perform.

An exhaust duct unit (3120) communicates with the other side of the duct (100) and extends upward, and an exhaust unit (2000) is disposed at a distal end thereof.

The exhaust unit 2000 functions to clean dust and contaminants generated in the process of removing the coating material and painting the inner wall before discharging it to the outside air, and may further include a dust collecting unit 2010 for dust separation .

On the other hand, it is preferable that the air purified and exhausted from the exhaust unit 2000 is capable of generating odors from the inside of the pipeline 100, and is provided with deodorization means together with purification and noise elimination.

In the process of removing paint, conventionally applied collet enamel is known to cause environmental pollution and promote corrosion of pipelines. Since the chalcote particles have a minute size, they may cause serious problems when they are sucked into the human body. Further, separation of the flow path and the entrance and exit by the door assembly 3200 of the present invention and maintenance of the internal airtightness are more meaningful. The airtightness described in the present invention does not necessarily mean a degree of completely blocking partial leakage of the air, but it is sufficient that the dustproofing can be performed to some extent.

The emergency parts of the air supply unit 1000 and the exhaust unit 2000 can function to provide emergency air when a fire occurs or when the main body parts are shut down, thereby preventing suffocation can do.

In order to operate the air supply unit 1000 and the air exhaust unit 2000, an external power source needs to be installed separately. When supply of air from the air supply unit 1000 is stopped due to a short circuit, There is a possibility that an accident occurs in the interior of the vehicle 100. The door assembly 3200 on the side of the air supply cutout 110 may be connected to the emergency supply unit 3300 through the emergency supply pipe 3310 for supplying air in an emergency.

In addition, as described above, the survival module 400 may be provided at each location of the connection line portion 401 in the pipeline 100. The survival module 400 may be equipped with sensing means to sense the humidity or temperature as well as the occurrence of a fire. Basically, the air supply unit 1000 can function as an element of judgment in air conditioning . Of course, the survival module 400 may measure both the temperature and the humidity as well as the carbon dioxide and oxygen concentration. A detailed description thereof will be given later.

More specifically, the air supply unit 1000 basically includes a filtering unit for removing contaminants from the outside air, a cooling dehumidifier for inducing condensation of moisture in the air through a cooling cycle, a heating unit for heating the cooled dehumidified air, A dehumidifying part for performing dehumidification in a second order by absorbing moisture and a temperature adjusting part for finally controlling the temperature before entering the channel.

The cooling and dehumidifying unit (not shown in the figure) performs the primary dehumidification with respect to the filtered outside air, and performs a dehumidifying function by causing the heat exchanger to condense the moisture contained in the air using the cooling cycle of the refrigerant. A heat exchanger disposed in a flow path of the air absorbs heat of the low-temperature / low-pressure refrigerant passing through the expansion valve against air to perform cooling.

It is preferable that a plurality of cooling cycles and / or heat exchangers are arranged for efficiency of dehumidification considering the flow amount of air through a water pipe of a large diameter. The cooling and dehumidifying part cools the outside air to a dew point temperature, thereby inducing a saturation state and causing condensation to occur. The dehumidified and cooled air through the cooling dehumidifier is heated again through a heating unit (not shown), and the heated air is dehumidified, and the dehumidification process can be efficiently performed by a dehumidifier (not shown). Therefore, the dehumidifying part performs dehumidification in a secondary way, while the dehumidifying part performs dehumidification in such a manner that the predetermined moisture absorbing particles absorb the moisture of the air and increase the water content therein desirable.

In the present invention, dehumidification in two different ways is performed in two steps, so that dehumidification in the air can be effectively performed. That is, in the case of coagulation and dehumidification in the cooling system, it is useful when the moisture content is relatively high. When the moisture is absorbed through the moisture absorption particles, the dehumidification capacity is small. However, when the moisture content in the air is low, the dehumidification can be more efficient. The air having passed through the dehumidifying portion and finally having its moisture removed is adjusted to a temperature optimized for the working environment by a temperature control portion (not shown) and is supplied to the duct 100 through the air supply duct portion 3100 and the door assembly 3200. [ It can be injected inside.

In the embodiment of the door assembly 3200 according to the present invention, the inlet path and the intake and exhaust path can be formed separately, thereby achieving both the efficiency of ventilation and the convenience of access.

Specifically, the door assembly 3200 includes a pipe connecting portion having one end connected to the end side of the incised pipe 100, a door portion formed at the other end of the pipe connecting portion and capable of entering and exiting, And a duct connecting portion capable of connecting the duct portion or the exhaust duct portion. Since the channel connecting portion is connected to the channel 100 at one end thereof, the channel connecting portion substantially corresponds to the diameter of the channel 100. When considering the airtightness, the channel connecting portion 100 is inserted into the inner circumference side, The coupling can be made in such a manner that the coupling is inserted. A sealing member such as silicon or a member such as a film or a tape that is disposed in a form to surround the gap may be additionally disposed at the coupled portion of the pipe connection portion and the conduit 100 in order to improve airtightness. The door portion forms an entry / exit path and is disposed in an opening through which the operator can enter and exit.

In addition, the air discharged from the heating portion can selectively pass through the bypass flow path and the dehumidifying portion. By controlling the amount of flow to the bypass flow path and the dehumidifying portion, it is possible to accurately and efficiently control the humidity. To this end, a damper portion for branching the flow may be further provided in the previous stage of the bypass flow path and the dehumidification flow path. The damper unit can be controlled in such a manner that a plurality of blocking plates are rotated so that the amount of air flowing through the bypass path and the dehumidifying path can be adjusted between 0 and 100%, respectively.

5 is a view for explaining an embodiment in which the interlocking type in-pipe combined ventilation system according to the present invention is operated according to a fire position and an operator's position.

In the illustrated embodiment, the hybrid control unit 200 senses the state of the pipeline 100 in relation to the connection line unit 401 and optimally controls the flow according to the situation. The illustration of the air supply unit 1000, the exhaust unit 2000, and the duct unit is omitted for convenience of explanation.

The survival module 400 is provided at each location of the connection line unit 401 as described above and monitors the internal situation to transmit to the hybrid control unit 200. The hybrid control unit 200 controls the units So that the state of the inside of the pipeline 100 can be checked from outside. For this, the hybrid control unit 200 may include a predetermined display or alarm device, and may be capable of transmitting monitoring status remotely so that a single or a plurality of channels can be integrally controlled have.

As shown in the figure, the interlocking type in-pipe combined ventilation system according to the present invention basically checks the fire generation point a and the work position β and performs various controls for the best survival thereof, Including the control of flow in the conduit, but also includes the indication of the evacuation direction, the supply of raw-oxygen, and the emergency contact. Additional concepts of survival module 400 are described below.

5A shows a case where the working position β is arranged before the fire generation point α with respect to the flow direction of the air supply flow path 311. In this case, in the survival module 400 disposed at the fire occurrence point α, the occurrence of a fire is transmitted to the compound control unit 200 through the connection line unit 401 through detection of carbon dioxide or temperature, The survival module 400 recognizes the position of the worker and transmits it to the compound control unit 200 through the connection line unit 401. At this time, the work position (?) Of the worker can be confirmed by an active operation through an infrared sensor or a temperature sensor provided in the survival module (400). In some cases, the operation of the survival module A user may be considered to operate manually through the connection of the intercom or the input to the fingerprint recognition device.

At this time, the hybrid control unit 200 may determine the evacuation direction [gamma] in consideration of the fire occurrence point [alpha] and the work position [beta], and direct the worker to a survival possible evacuation direction through the survival module 400 . The instruction may be made in such a manner as guidance of voice through a speaker, display of a display unit (450 of FIG. 6) having light emitting means, and the like.

In addition, in the case of FIG. 5 (a), the mixed controller 200 can determine the control direction and the degree of the flow so that the operator does not suck the toxic gas. The composite control unit 200 can keep the direction of the air supply equal to that in the work environment. However, as described above, the formation of the flow is prevented by closing the first air supply damper 1911 of the air supply unit 1000 and / or by closing the first exhaust damper 2911 of the air exhaust unit 2000 to stop the supply of the outside air And to suppress the spread of fire.

5 (b) shows a case where the fire generation point? Is placed ahead of the work position? With respect to the flow direction of the flow through the air supply flow path 311. Fig. In this case, the hybrid control unit 200 can instruct the escape direction? In a direction away from the fire point?, And can switch the flow. The switching of the flow can be performed through the switching exhaust passage 312 and the switching air supply passage 322. In this case, as described above, the flow can be shut off and the diffusion of the fire can be suppressed first.

Meanwhile, the hybrid control unit 200 recognizes the position of the worker as the survival module 400 in real time, recognizes the evacuation progress state, and in the process of evacuation, the direction of the toxic gas is reversed from the evacuation direction And then, in the state where the evacuation is completed, the flow may be blocked to suppress the fire. If the operator is not disposed, the air supply unit 1000 and the exhaust unit 2000 may form a flow in the direction in which they are discharged, thereby lowering the oxygen concentration in the pipeline 100 to further improve the efficiency of fire suppression . In addition, fire-fighting equipment such as a fire extinguisher may be provided at each location of the pipeline 100 to suppress the fire.

At this time, it is determined that the fire generation point is at the corresponding position, and the optimal escape route and the flow control are performed by comparing the direction of the flow with the respective working positions [beta], as described above.

In order to display the evacuation direction [gamma], the display unit 450 can display the evacuation direction, which can be expressed in the form of an arrow for easy recognition. In some cases, the lamp unit 403 may be oriented in both directions to inform the inside operator of the evacuation direction (gamma) by emitting light or flickering.
