In this case, each disk may be implemented as a storage medium, such as a hard disk drive (HDD), an optical disk drive (ODD), or a solid state disk (SSD).

Meanwhile, the block-based parallel direct storage method used in the present invention can selectively control each disk by using unique MAC address information of the board, It is possible to speed up the storage speed by sequentially storing the data on the respective disks.

In the case of the file unit storage method, unnecessary header information of a packet and a continuous input / output (I / O) signal are generated, a transmission amount and a frame are reduced while a file system transmits a packet, By storing in a sequential manner rather than in a sequential manner, the storage speed is slow compared to the slow.

The vehicle detection unit 120 is an Automated Vehicle Classification (AVC) for calculating the traffic parameters such as the speed of the vehicle and the type of the vehicle that is traveling into the tunnel. The vehicle detection unit 120 is installed under the ground of the road, (Not shown), a loop sensor (not shown), and a second piezo sensor (not shown).

In this case, the first and second piezo sensors are installed with the loop sensor interposed therebetween. In this case, the first and second piezo sensors sense the vehicle in operation and calculate the traffic parameters such as the vehicle speed, the axial coefficient, , And the loop sensor detects the vehicle in operation to determine the presence or absence of the vehicle, the length of the vehicle, and the traffic volume.

Preferably, the fault type determination unit determines whether the first piezo sensor, the second piezo sensor, or the loop sensor is faulty so that the traffic parameter calculation unit may calculate traffic parameters for each vehicle in operation according to the fault type. It does.

In this case, the fault types of the sensors are as follows: one of the Piezo sensor is broken (fault type 1), one of the loop sensor is broken (fault type 2), one Piezo sensor and one Loop sensor (Failure type 3), and failure of both Piezo sensors (failure type 4).

The tunnel sensing unit 130 includes a gas concentration sensing unit 131, a dust generation sensing unit 132, and a smoke sensing unit 133.

The gas concentration sensing unit 131 is for sensing the concentration of gas in the tunnel and determines whether the gas purifying unit operating unit 170 is operated according to the degree of contamination of the detected gas concentration.

The dust detection unit 132 detects whether dust is generated in the tunnel more than a predetermined reference value. If the dust is greater than the reference value, the dust generation detection unit 132 transmits a dust generation detection signal to start the operation of the fan operation unit 160.

The smoke detection unit 133 detects whether or not smoke caused by a fire in the tunnel is generated and generates an alarm when a fire occurs so that the vehicle in the tunnel can be evacuated urgently.

The communication unit 140 implements communication with an external terminal such as Zigbee, RF, WiFi, 3G, 4G, LTE, LTE-A, Wireless Broadband Internet Communication, or Internet, or SNS (Social Network Service).

The tunnel information processing unit 150 includes a tunnel information collecting unit 151, a tunnel information analyzing unit 152, a tunnel information managing unit 153 and a tunnel information monitoring unit 154.

The tunnel information collection unit 151 collects the tunnel information acquired by the tunnel photographing unit 110, the vehicle detection unit 120, and the tunnel detection unit 130 through wired / wireless communication.

The tunnel information analyzing unit 152 analyzes the tunnel information collected by the tunnel information collecting unit 151 to determine the degree of cracking of the wall of the tunnel, whether or not there is a fire in the tunnel, a traffic accident of the vehicle inside the tunnel, , Whether or not exceeding the threshold value of dust generation in the tunnel, and whether the illumination in the tunnel is broken.

The ventilator operating portion 160 includes a first ventilator operating portion 161 and a second ventilator operating portion 162. [

Since the first ventilator operating section 161 maintains the mutual pressure balance of the tunnel section divided by the ventilation vent for the concentrated exhaust, it is possible to actively concentrate ventilation, thereby reducing the cross section of the main tunnel by 10 to 15% And provides a means for reducing the size of the ventilator, which will be described in detail below with reference to FIG.

 2 shows a method of ventilating a road tunnel using a first ventilator according to the present invention.

2, at least one ventilation jet fan 10 for introducing fresh air Pj1 to the outlet side is provided at the inlet side of the tunnel T, and a reverse airflow Pj2 ) Are formed so as to maintain the pressure balance, and at least one jet fan 12 for balance control is provided.

At this time, the installation number of the ventilation jet fan 10 and the balance control jet fan 12 may be increased or decreased according to the ventilation capacity or the cross-sectional size of the tunnel.

A flue gas duct 14 is provided between the ventilation jet fan 10 and the balance control jet fan 12.

The exhaust duct 14 is normally used for concentrated exhaust according to traffic conditions (traffic volume or traffic speed), and is used for exhausting smoke in the event of a fire. The exhaust duct (14) is provided with a damper (14a) which can be opened and closed at regular intervals.

The ventilation duct (14) is connected to the ventilation opening (16) for concentrated exhaust. At this time, the connection position of the concentrated exhaust ventilation port 16 is set to a neutral point O where the traffic ventilated from the inlet side of the tunnel T and the external natural wind Pm flowing from the outlet side of the tunnel T are joined.

Therefore, the tunnel T can be divided into the first section L1 and the second section L2 on the basis of the neutral point. An exhaust fan (18) for generating exhaust power is provided in the central exhaust ventilation port (16). At this time, the exhaust fan 18 may be an axial flow blower.

In this embodiment of the present invention, the ventilation jet fan 10 and the balance control jet fan 12 are installed on both sides of the tunnel T so that the flow rates of the first section L1 and the second section L2 are It can be controlled independently.

That is, if the ventilation capacity of the first section L1 exceeds the ventilation capacity which can be additionally treated by the ventilation jet fan 10, the air volume of the second section L2 increases. In this case, a resistance is formed in the direction opposite to the air flow by the balance control jet fan 12 installed in the second section L2 to control the balance.

Accordingly, the present invention can ensure the ventilation qualities for all situations even if only six jet fans and four exhaust fans are provided in the tunnel of 4.5 km, and the ventilation jet fan 10 and the balance control jet fan 12 The operation power ratio can be reduced and the installation area of the centralized exhaust ventilation port 16 can be minimized and the ground area and the construction cost of the ventilation can be reduced.

Next, the second ventilator operation unit 162 is provided with a water tank having a different size at regular intervals along the bottom of the tunnel so that clean air can be continuously circulated and supplied by a natural- And the hot air from which the soot and the gas are separated by the water tank suction device is guided through the air discharge port formed on the wall surface of the tunnel to the air discharge passage pipe And then discharged to a chimney through a natural ventilation system. A detailed description thereof will be given below with reference to FIG.

3 shows a method of ventilating a road tunnel using a second ventilator according to the present invention.

3, a water tank suction device 20 for dividing the bottom of the tunnel 21 and supplying cold water of water continuously supplied to the water tank 22 is provided on both sides of the wall of the tunnel 21, ) On the wall surface, the cold air supplied from the water tank suction device (20) and the contaminated hot air discharged from the vehicle by the outside air are sucked by the convection phenomenon and the gas is sucked into the water tank (22) The air ascends and discharges to the chimney 33 through the air outlet 35.

The water tank suction device 20 has a plurality of water tanks 22 having a predetermined size and spacing in the bottom of the tunnel 21. The reason for varying the sizes of the water tanks 22 is as follows. So that the cold air supplied into the tunnel 21 and the soot and gas sucked in can be sucked smoothly.

A water supply circulation pipe is installed to circulate the water supplied to the water tank 22 at the lower part between the embedded water tanks 22 and the water tank 22 located at one end of the plurality of water tanks 22 22 is formed with a water level control pipe 23 for discharging water supplied to regulate the water level of the water tank 22 arranged in a row in a water supply pipe for supplying water and a water tank 22 located at the other end do.

A plurality of air inlets are formed toward the inlet of the tunnel 21 formed on both sides with respect to the main water tank 22 buried in the center of the bottom of the tunnel 21 on one wall surface of the tunnel 21, And the other is connected to the other water tank 22, a part of the air supplied from the outside is supplied through the air inlet and a part is supplied into the water tank 22 And external air is supplied from the center of the tunnel 21.

Then, the contaminated air in the inside of the tunnel 21 rises to the top of the tunnel 21 due to a temperature difference with the air supplied from the outside.

Meanwhile, in order to supply air to the air inlet, a separate air inlet passage pipe may be installed at the entrance of the tunnel for direct connection.

In order to discharge the rising contaminated air to the outside, one side is branched so as to be connected to the cold air discharge and the soot and gas inlet 24, and the other side is connected to the air discharge connection pipe 27, And the air discharge port 35 is provided with an air discharge passage pipe 34 to discharge bad air to the chimney 33 formed to protrude from the mountainous region 38 located to the left and right of the tunnel.

The position of the chimney 33 is preferably provided on both sides of the inlet of the tunnel 21, or on the lower side of the support.

On the other hand, the chimney effect refers to the smoke-air flow through the vertical space of the building (convection phenomenon) due to the density difference according to the temperature difference between inside and outside air.

In normal conditions, the natural air flow in the building is mostly chimney effect. In the case of a high-rise building fire, this chimney effect spreads smoke and toxic gas widely through elevator chute, linen suit, plumbing chute and stairs .

That is, when the industrial exhaust gas is blown out at a low place, the diffusion range is narrow, so that the environmental pollution is serious, but when it is sprayed to a high place, the diffusion range becomes wider and natural purification becomes possible.

An embodiment of the inner wall structure of a road tunnel according to the present invention will be described with reference to FIG.

4 is a view showing a structure of a structure of an inner wall of a road tunnel according to the present invention.

4, the structure of the inner wall of the road tunnel according to the present invention includes a tunnel inner wall 41, a tunnel illumination lamp 42, a blower 43, a partition wall (first partition wall 44) and a second partition wall 45 40).

In this case, a partition wall 40 that forms the air flow passages a1 and a2 is provided, while the blower 43 is installed.

The partition wall 40 is installed on the ceiling surface of the tunnel inner wall 41 and extends in the longitudinal direction of the tunnel to form an air flow passage so as to gather air to the upper portion of the tunnel inner wall 41. Inside the air flow passage The blower 43 is located.

The partition wall 40 includes a first partition wall 44 fixed to the ceiling surface of the inner wall 41 of the tunnel while being positioned on both sides of the fan 43 and a first partition wall 44 And a second partition 45 extending toward the lower surface of the tunnel.

That is, the partition wall 40 further forms one inner wall inside the tunnel. Since the partition wall 40 is mainly used to form one inner wall, it is not required to have a large structural rigidity, and therefore, it is preferable that the partition wall 40 is made of a light metal material while being required to be resistant to heat.

It is preferable that the height of the first partition wall 44 is larger than the height of the blower 43 in the tunnel so that the flow of air formed by the blower 43 is not scattered in the direction of the bottom surface in the tunnel.

The first partition wall 44 is formed straight in the tunnel toward the lower surface, but may be formed in an arc-shaped cross section centering on the blower 43.

However, the first partition wall 44 may be variously modified as long as it forms an air flow passage and collects air trapped in a region corresponding to the upper portion of the tunnel and confines it.

The second partition wall 45 serves to guide the air or smoke in the tunnel to be collected into the air flow path formed by the first partition wall 44 in the process of rising due to the difference in specific gravity.

Accordingly, it is preferable that the second partition wall 45 has a curved cross-section, but it may have a straight cross-section or other deformed shape as it goes from the bottom to the top of the tunnel.

Further, the tunnel illumination lamps 42 may be provided on one side of the second partition 45.

Next, the gas purifier operating unit 170 operates the gas purifier installed in the tunnel based on the gas concentration in the tunnel detected by the tunnel detector 130, the degree of dust generation, Moisture, oil and air pollutants in the air are removed. A detailed description thereof will be given in FIG. 5 below.

5 shows the structure of an air purifier in a road tunnel according to the present invention.

Referring to FIG. 5, the air purification apparatus in a road tunnel according to the present invention includes a dehumidifier 51, a dust collector 52, a catalytic reactor 53, a plasma reactor 54, and a blower 55.

The dehumidifier 51 removes moisture in the air inside the tunnel. That is, the dehumidifier 51 receives the air in the tunnel in the state of being installed in the tunnel, removes moisture, and discharges the dust to the dust collector 52 to be described later.

The dehumidifier 51 may remove moisture from the air inside the tunnel through a dehumidifying agent, a dehumidifying filter, or a heating system. However, the present invention is not limited thereto.

Thus, since the moisture in the air inside the tunnel is removed by the dehumidifier 51, the cleaning efficiency is increased while improving the contact ratio of the carbon monoxide and the catalyst in the air supplied to the catalytic reactor 53 thereafter.

In addition, the dehumidifier 51 may be provided with a humidity sensor (not shown) and a humidity controller (not shown).

After the humidity sensor senses the humidity in the air, the humidity sensor compares the humidity in the air supplied to the dust collector 52 with the reference value in the catalytic reactor 53, Can be adjusted.

 The dust collector 52 removes fine dust in the air inside the tunnel. That is, the dust collector 200 is connected to the dehumidifier 51 and receives dehumidified air through the dehumidifier 51 to remove fine dust, and then the air is discharged to the catalytic reactor 53.

The dust collector 52 may remove fine dust in the air supplied from the dehumidifier 51 through a filtering filter, a cyclone, or an electric dust collection system (see FIG. 6). However, Of course, it is possible to apply the means.

6 shows the structure of a multi-layer filter medium for polluted air purification in a road tunnel according to the present invention.

Referring to FIG. 6, the polluted air filter medium for polluted air purification in a road tunnel according to the present invention includes a first sponge, a second sponge, and a second sponge so as to be cleaned by passing polluted air, which has undergone a pretreatment process for oxidizing nitrogen monoxide to nitrogen dioxide, A layer 61, an air distribution layer 62, a mixed media layer 63, and a second sponge layer 64 in this order.

The first sponge layer 61 is initially made of a sponge having a porosity of 10 to 50 ppi so that the contaminated air is firstly passed through, the fine dust is primarily removed, and the moisture is retained therein, and the nitrifying bacteria are seeded.

In this case, the nitrifying bacteria include nitric acid bacteria and nitrite bacteria, whereby the nitrogen dioxide becomes nitric acid form.

The air distribution layer 62 has a predetermined gap and functions to uniformly supply the contaminated air having passed through the first sponge layer 61 to the mixed media layer 63. As such an air distribution layer 63, it is preferable to use an alkaline coral quartz or limestone layer having a particle diameter of 0.5 to 3 cm.

This is because the nitrogen dioxide is absorbed into the water and the nitrate ion is formed, so that the polluted air is acidified. The alkaline coral layer or the limestone layer functions to neutralize the polluted air that has acidified to improve the absorption ability of nitrogen dioxide.

The mixed medium material layer 63 is uniformly mixed with calcined clay, marcasite and granular zeolite. The calcined clay is an artificial soil calcined at a high temperature of about 1200 ° C by mixing clay and water, and functions to increase water content and porosity. Masato is formed by weathering granite and provides a habitat environment of microorganisms. Zeolite is a hydrate of aluminum silicate, which is provided in granular form as a mineral, has ion substitution ability and functions to increase adsorption effect and water content.

It is preferable that the mixed media 63 is 50 to 100 cm in view of the experimental results. If the thickness of the mixed media layer is small, the treatment efficiency is low. If the thickness is too large, the increase in the treatment efficiency relative to the thickness is small, and the restriction on the installation of the purification device is limited.

The weight ratio of the calcined clay, the marble and the zeolite is preferably 1: 2 to 5: 0.2 to 0.5. The mixing ratios of these materials are considered to ensure the economical efficiency according to the unit price of each material, and the cost and treatment effects are considered.

At this time, it is preferable that the water content of the mixed media 63 is maintained at 50 to 80% in order to provide a microbial habitat environment and to increase the absorption rate of nitrogen dioxide. If the water content is too high, the water permeability will be low, so the water content must be controlled.

The second sponge layer 64 functions in the same manner as the first sponge layer 61 described above, and nitrifying bacteria are seeded.

The thickness of each of the above-described layers is 5 to 20 cm for the first sponge layer 61, 15 to 40 cm for the air distribution layer 62 using the coral quartz or limestone layer, 50 to 100 cm for the mixed media layer 63, The sponge layer 64 is preferably 5 to 20 cm.

At this time, the thicknesses of the first sponge layer 61, the air distribution layer 62, and the second sponge layer 64 excluding the mixed media 63 can be appropriately adjusted according to the installation conditions of the polluted air purification apparatus.

Next, the catalytic reactor 53 removes carbon monoxide in the air inside the tunnel. That is, the catalytic reactor 53 is connected to the dust collector 52 and is supplied with the dust-removed air through the dust collector 52 to remove the carbon monoxide, and then discharged to the plasma reactor 54.

The catalytic reactor (53) removes carbon monoxide in the air supplied from the dust collector (200) by a catalytic reaction.

For example, a room temperature catalyst (not shown) is inserted into the tubular body (not shown) of the catalytic reactor 53. At this time, the room temperature catalyst is introduced into an inlet (not shown) To maintain the removal efficiency of the carbon monoxide discharged from the plasma reactor 54 through the catalytic reaction at a low temperature of 25 ° C or lower.

The plasma reactor 54 removes volatile organic compounds in the air inside the tunnel. That is, the plasma reactor 54 is connected to the catalytic reactor 53 and is supplied with the air from which the carbon monoxide is removed through the catalytic reactor 53 to remove the volatile organic compounds, and then discharged to the outside of the tunnel.

The plasma reactor 54 removes the volatile organic compounds in the air supplied from the catalytic reactor 53 by a plasma reaction.

In this way, the plasma reactor 54 generates corona discharge on the high-dielectric body filled between the discharge electrodes (not shown), while decomposing the volatile organic compounds in the air when the air introduced into the body passes through the dielectric .

The blower 55 allows the air inside the tunnel to be discharged to the outside of the tunnel. That is, after the air in the tunnel flows into the dehumidifier 51, the air blower 55 sequentially moves the dust collector 52, the catalytic reactor 53, and the plasma reactor 54, .

Finally, the integrated control unit 180 includes a tunnel photographing unit 110, a vehicle detecting unit 120, a tunnel detecting unit 130, a communication unit 140, a tunnel information processing unit 150, a fan operating unit 160, And controls the device operation unit 170.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. 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 of the invention.
