Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a location information providing system,

The present invention relates to a position information providing system using an information communication device in an information communication technology field. More particularly, the present invention relates to a position information providing system using an integrated parking lot information management system which is a terminal including a sub- It is possible to extend the system and to manage parking garages where GPS information does not reach. It is improved to build a nationwide parking management system controlled by one main server management rather than an individual parking management system. In addition, The present invention relates to a location information providing system using an information communication device that increases refractoriness of a housing in which a server constituting a system is built and maintains the system clean and cool at all times, thereby preventing system deterioration.

Generally, large-sized buildings, large department stores, shopping centers, large discount stores, and public institutions, such as a large number of underground car parks, However, most of the parking lot is mobilized and guided during the guidance for each floor.

In addition, a parking guidance system has been known in the prior art in which a vehicle detector is provided for each parking area to automatically provide parking guidance information. However, this is merely a guide for the number of parking spaces for each floor of a parking lot, The driver often wanders around the parking space. Therefore, a lot of time and effort is wasted in securing the parking space, and the waste of manpower due to the arrangement of the parking staff is extremely serious.

In addition, urban parking spaces are becoming more integrated and larger. In some large parking buildings, only the information about the number of parkable vehicles is provided, but accurate parking spaces and their locations can not be grasped in real time.

Furthermore, in the case of an underground parking lot located in an underground space, it was impossible to obtain the information related to the parking lot by utilizing the GPS alone.

Recently, the concept of U-Parking service that can provide various convenient functions such as automatic recognition of vehicles, settlement of parking fees, and occupancy analysis of parking areas based on video recognition technology, sensor recognition technology, and network technology Is emerging.

For example, a technology related to parking dedicated management using image information is disclosed in "Parking management system and method" developed by the Kyungpook National University Industry and University Collaboration, 2009-0020533 (2009.02.26), developed by NEXPA system "Parking management system and management method" of registered patent No. 0844478 (2008.07.01), "Patented parking management system using camera", registered patent No. 0830844 (2008.05.14) developed by Koryo Dynamics have.

Another example is a technology related to parking dedicated management using a driver mobile device. For example, a mobile communication terminal equipped with a smart card disclosed in Patent Publication No. 2007-0076009 (2007.07.24) developed by Pantech Co., A parking management method and system used ".

Another example is a technique relating to parking management using sensor data. For example, a parking management system, a sensor node and its parking management method developed by Esenal Co., Ltd. No. 0909436 (2009.07.20) "Intelligent system and method of u-city" developed by KT, 2009-0035378 (2009.04.09), Published patent application 2008-0026282 (2008.03.25) developed by SK Telecom Co., Ltd. " A parking management system and method using RFID ", and a parking management system developed by KyuField Co., Ltd. No. 0306714 (Feb. 23, 2003).

However, since these types of parking management systems have different facilities for individual parking lots, they are not compatible with each other, resulting in poor efficiency.

In addition, since various sensors are installed in the parking lot to check whether the parking is available and the parking lot is integratedly managed for each parking lot, there is a disadvantage that the initial installation cost as well as the management cost are greatly increased.

In addition, there is a disadvantage in that labor costs are increased and excellent facilities are provided, because the maintenance personnel need to be set aside, and when the different devices are used, the service is not provided and the maintenance cost increases.

The information retrieval and processing unit 120 includes a data retrieval / extraction module 122 and a data mining module 124, as shown in FIG.

At this time, when the parking lot map and available space information request message are transmitted from the interaction processing unit 110, the data search / extraction module 122 searches the integrated parking lot management DB 130 for the information of the corresponding parking lot and outputs the result to the interaction processing unit 110, and the integrated parking lot management DB 130 needs to manage the current state of a large number of parking lots and a lot of parking spaces existing in each parking lot in real time, so that it can be quickly retrieved and extracted .

The data mining module 124 performs a data stream clustering algorithm, which is one of the data mining techniques, on the basis of the coordinate system based on the space information on which the driver frequently parks the parking space, And a two-dimensional or three-dimensional spatial coordinate value data generated for each driver through a grid-based clustering technique of a dynamic structure for data transaction processing by transmitting the two-dimensional or three-dimensional spatial coordinate value data to one data transaction at the time of occurrence.

For example, as shown in FIG. 3, each data transaction is divided into a corresponding range of grid cells, and adjacent data objects are determined as one cluster based on statistical values of the frequency and distribution, and are periodically or compulsively Data can be mined by searching all the grid cells and adjusting the size of the grid cells by performing a pruning process on the grid cells less than the cell support degree.

On the other hand, the integrated parking lot management DB 130 is a large-capacity database system for storing and managing the area-specific parking lots to be managed, the space information for each parking lot, the current parking space and the information of the vehicles in the current parking lot.

2, the database includes a parking lot map DB 132, a real-time parking space availability DB 134, and real-time waiting vehicle information DB 136. Since each data group has different data update and query request cycles, individual indexing and database integration management techniques are applied so as to minimize the time required for accessing these databases.

At this time, the area-specific parking map DB 132 is a database that can register and delete the parking lots to be managed for each area, and stores a map of the parking areas of the parking lots, the total parking available quantity, and the like.

And, it provides a map image of the parking lot at the time when the vehicle enters the parking lot, and the frequency of access is very low and semantically higher than other database groups.

The real-time parking space availability management database 134 is a database used for searching a parking space currently available in each parking lot. The search process is performed once according to the entry of the parking lot of the vehicle, and the result is transmitted together with the parking lot map. And the retrieved available space results are transmitted to the navigation service provider 114 of the interaction processing unit 110 and displayed on the in-vehicle navigation terminal.

In addition, the real-time waiting vehicle information DB 136 is a database for storing information of a plurality of vehicles that are currently waiting in the parking lot, that is, not in a parked state. When a plurality of vehicles receive the same parking available space, The vehicle must immediately provide a list of new available spaces so that it keeps information about available space as well as all vehicle information currently in the parking lot.

In addition, when the parking space information is changed, the changed space information is broadcasted to the currently waiting vehicles.

Since these database groups exist in a concept space that is logically and physically different from each other, it is essential to synchronize and share / distribute a large amount of data transactions. Also, because it uses web-based network communication, securing the stable bandwidth of each regional database can be an important parameter for the performance of the whole system.

In addition, the administrators of each parking lot must register and manage unique information of the corresponding parking lot (floor plan information, parking space information, inside distance information, entrance GPS value information, altitude information and tilt information, etc.) do.

In other words, as shown in FIG. 4, in the case of information dynamically changed due to parking and departure of the vehicle, application to the information does not require any management work by the administrator, and integration with the Internet interlocking navigation system 300 In the integrated parking lot information management system 100, when there is a request from the navigation terminal of each user vehicle, the integrated parking lot information management system 100 accesses the local data group allocated to the corresponding area, The query is processed on the local data group of the corresponding region, so that the traffic for the entire system is dispersed. In this case, Effect.

The vehicle position information processor P includes a position information integration module 240 and a position information determination module 250 ).

At this time, the wireless AP information receiving module 230 is an illustrative example and represents a plurality of sensors installed in the parking lot for location.

Thus, the vehicle position tracking system 200 performs a function of calculating the current position of the vehicle in real time through various sensor data including GPS satellite data in the driver's vehicle and transmitting the calculated position to the Internet interlocking navigation system 300 .

In this case, in the area where the GPS satellite data is received, basically, the position of the vehicle is determined by the information received by the GPS receiving module, and when the vehicle enters the shadow area of the GPS such as the underground parking lot and can not receive the GPS information The position of the vehicle is estimated using various types of sensors installed inside the vehicle, and the estimated position is transmitted to the system.

To this end, the vehicle position tracking system 200 receives all information related to the vehicle position and receives GPS information, various sensor information in the vehicle, and wireless AP (access point) signal information, A vehicle position information receiver R for transmitting the vehicle position information to the vehicle position information processor P; And a vehicle position information processor P for determining a vehicle position by assigning weights for the accuracy of various sensors to the function of determining the position of the actual vehicle by integrating the information transmitted from the vehicle position information receiver R. [

The vehicle position information receiving unit R includes a GPS receiving module 210, a sensor data receiving module 220 and a wireless AP information receiving module 230. The GPS receiving module 210 receives the GSP coordinate information And the sensor data receiving module 220 functions to receive four pieces of sensor information installed in the vehicle, and the wireless AP information receiving module 230 receives the IDs and locations of the APs installed in each floor of the parking lot, And receives the AP information when the information is valid through the Internet.

At this time, the four sensors may be an electronic compass 222, a gyro sensor 224, a three-axis acceleration sensor 226, and an altitude sensor 228.

The vehicle position information processing unit P includes a position information integration module 240 and a position information determination module 250. The position information integration module 240 receives the position information from the individual modules of the vehicle position information reception unit R, And transmits the received various reception information to the position information determination module 250. The position information determination module 250 analyzes the information about the final vehicle position received from the position information integration module 240 In the case of a GPS shaded area, an electronic compass 222, a gyro sensor 224, and a GPS receiver 3 are used to estimate the position of the vehicle. Axis acceleration sensor 226, and altitude sensors 228, and estimates the real-time rotational direction and the moving direction of the vehicle from them, thereby finally estimating the position of the vehicle.

10, the electronic compass 222 provides omnidirectional azimuth information of the vehicle, the information is pre-processed / corrected and utilized, the gyro sensor 224 provides 3-axis rotational angular velocity information , Which is integrated, transformed into a three-axis rotation angle, and then preprocessed / corrected for use as information.

In addition, the three-axis acceleration sensor 226 provides the forward, lateral, and gravity direction acceleration information of the vehicle, which is double-processed and converted into a forward movement distance, a lateral movement distance, and a gravity direction movement distance of the vehicle After being preprocessed / corrected, the information is used as information, and the altitude sensor 228 provides altitude information and is used to discriminate the number of floors where the vehicle is located.

However, in the case of a multi-storey car park, the number of parking lots into which the vehicle has entered is a very important factor. In order to identify the entry layer, altitude information from GPS, vertical acceleration change information of the three- And identifies the entrance of the vehicle by additionally using the information received from the wireless AP information receiving module 230 when the information received from the wireless AP information receiving module 230 is valid.

On the other hand, as shown in FIG. 6, the Internet-linked navigation system 300 is linked to the integrated parking lot information management system 100, which is a main server, mounted on an individual vehicle together with the vehicle location tracking system 200, A sub-system for receiving, in real time, parking lot information necessary for parking the driver and available parking space information, and displaying the information to the driver and processing the input of the driver.

The internet interlocking navigation system 300 includes a parking lot information processing unit 310, a wireless Internet communication unit 320, an in-vehicle communication processing unit 330 and an optimal path processing unit 340, The parking lot information processing unit 310 includes a map profile management module 312 and an information request control module 314. The wireless Internet communication unit 320 includes an information transmission module 322, The in-vehicle communication processing unit 330 includes a user input module 332, a map display module 334, a moving path display module 336, and a spatial information display module 338 And the optimal path processing unit 340 includes an optimal path search module 342. [

The parking lot information processing unit 310 is a processing unit that receives necessary information and control information transmitted from the outside of the Internet linked navigation system 300 and distributes and controls necessary information to individual modules in the navigation system, The module 314 transfers the received information or controls the individual modules based on the necessary information and control information transmitted to the Internet interlocking navigation system 300. The vehicle position tracking system 200 detects the parking lot entry information of the vehicle Upon reception by the information request control module, the map profile management module 312 searches the parking lot map stored.

At this time, if there is no parking map, the wireless Internet communication unit 320 requests the map information of the entering parking lot and the available space information in the parking lot. If the map profile management module 312 already stores the parking lot map, Only the information request control is transmitted.

The parking lot map information is transmitted to the map profile management module 312 and the in-vehicle communication processing unit 330, and the available space information in the parking lot is transmitted to the optimum path search module 342 together with the map profile.

In addition, since the vehicle receives the real-time position information of the vehicle in the parking lot from the time the parking lot is entered until the parking is completed, the information is transmitted to the in-vehicle communication processing unit 330 so that the vehicle position information up to the parking position selected by the driver can be checked in real time And receives the parking position information of the vehicle at the time when parking of the vehicle is completed, and transmits the parking position information to the map profile management module 312 and the wireless Internet communication unit 320.

The map profile management module 312 manages the parking lot map information and the preferred parking position information that the driver visited, stores the individual parking lot map information and the final parking position, and based on the cluster information performed in the data mining module And profile and manage the parking position information preferred by the driver.

The wireless Internet communication unit 320 transmits and receives all required information and control information of the integrated parking lot information management system 100 and transmits the information to the information request control module 314 and the spatial information display module 338, The transmission module 322 transmits the request information required for controlling the Internet linked navigation system 300 and the position information obtained from the navigation system to the integrated parking lot information management system 100, When the entrance information is received and received by the parking lot information processing unit 310, the driver requests map information on the parking lot to be entered in the future and parking space available space information in the parking lot, which is the main server, to the integrated parking lot information management system 100.

When the user finally completes the parking using the information received from the main server, the vehicle position tracking system 200 receives the current parked position of the vehicle and transmits it to the integrated parking lot information management system 100 At the same time, user mobile service is requested.

The information receiving module 324 receives the requested information from the integrated parking lot information management system 100 as a main server and transmits information required for each module in the interlinked navigation system 300 to the integrated parking lot information management system 100, the control unit 314 transmits two pieces of information to the information request control module 314 for system control and transmits the available space information to the individual modules of the vehicle communication processing unit 330 The user is guided to select a desired parking position.

In addition, the in-vehicle communication processing unit 330 is a processing unit that displays all the services provided by the integrated system for location-based parking guidance and parking lot management and receives input from the driver. The map display module 334 displays, Which is operated by receiving map information of the corresponding parking lot from the information request control module 314 at the time when the driver enters the parking lot.

The space information display module 338 is a module for displaying space information that can be parked in the parking lot. The space information display module 338 provides the parking space information received from the wireless Internet communication unit 320 to the driver in real time until the parking is completed. The input module 332 is a sole module responsible for receiving the input of the driver by the Internet interlocking navigation system 300. The driver checks the map of the parking lot and available space information displayed on the screen of the navigation terminal and selects a desired location And the route display module 336 has a function of displaying the route to the parking position selected by the driver and outputs the route from the optimum route search module 342 to the destination parking position as an information request Receives the position of the vehicle from the control module 314, Is a display in real time the current position in the vehicle.

Lastly, the optimal path processing unit 340 searches for the optimal path up to the parking position selected by the driver and transmits the optimum path to the communication processing unit 330. The optimal path searching unit 342 includes an optimal path search module 342 As shown in FIG. 7, since the information expressed as the route is very simple, and the absolute size of the entire coordinate space is significantly smaller than that of the general navigation system, the optimal path search module 342 of the Internet- The path search algorithm used is differentiated from the path search algorithm of the general navigation system.

In other words, the low-cost optimized path search algorithm according to the present invention maximizes the mobility and data transfer efficiency rather than minimizing the travel distance in a space where the absolute size of the entire coordinate space is sufficiently small. A directional graph is generated based on this information, and a shortest path is found by adding a predetermined cost to the directional conversion on the derived graph. .

Accordingly, up to several dozen directional change point (node) information is used per parking space, which facilitates not only data transmission and reception, but also an error rate reduction effect. In addition, since the driver of the vehicle pursues the convenience of the operation rather than the efficiency obtained by the shortest distance, it is possible to recommend the route to the destination with a minimum weight by setting the cost in the direction change. The same is applied to the optimum path search module 430 of the guidance system 400.

On the other hand, the mobile parking position guiding system 400 is a subsystem that performs a function of providing a map image of a parking lot and its own vehicle position information to a driver's mobile terminal, as shown in FIG. 8, So that navigation can be provided in the mobile terminal by searching for the optimal route to the parked vehicle. In addition, when the driver has finished parking, it is preferable to include a function of guiding the position of the vehicle to the SMS service.

The mobile parking position guiding system 400 includes a wireless Internet communication unit 410 having a necessary information receiving module 412 installed therein, a GPS receiving module 420, an optimal path search module 430 and a display module 440).

At this time, the wireless Internet communication unit 410 receives the data transmitted from the mobile service provider 116 of the integrated parking lot information management system 100, and the transmitted data is the parking map image and the position information of the parked vehicle, It is possible to perform optimal route navigation using this information.

The GPS receiving module 420 performs the same function as the GPS receiving module provided in the other subsystem described above, and the optimal path searching module 430 is also described above.

Finally, the display module 440 provides navigation results to the driver at the mobile terminal.

At this time, the driver can be informed of the service information provided by the system, that is, the parking lot floor plan, his / her own vehicle location, and the current location of the user, on the screen of the terminal.

This is a service for solving the difficulty in finding a parked vehicle when the size of the parking lot is large. Internally, the map display module, the spatial information display module, the moving route display simulation And is implemented in the same manner as the performance function.

The system according to the present invention having such a configuration can be finally realized as shown in FIG.

Thus, it is possible to accurately grasp the position of the vehicle and to guide the user to the user even in an area where the GPS information can not be received through the vehicle location tracking technique utilizing various sensor information actively. In addition, Based on the analysis of parking behavior of individual users through mining technology, it is possible to provide preference recommendation service based on this. Also, by operating the integrated parking lot information management server for managing individual parking lots, it is possible to minimize the system requirements The present invention can provide a parking lot floor plan service for a user's mobile terminal and a real time parking position guidance service that can be requested anytime and anywhere. Without this request it is possible to build awareness and self-service possible ubiquitous service environment.

In addition, as shown in FIG. 11, the present invention is further provided with a refractory foam unit 610 in a housing 600 having a server of each system including the integrated parking lot information management system 100, It is constructed so that the fire can be suppressed promptly through the refractory blowing agent which expands rapidly by 300-400 times to protect the built-in electric and electronic parts.

That is, on both sides of the inside of the housing 600, a fire-proof foaming unit 610 is installed to prevent the equipment from being blown by spraying the refractory liquid onto the mounted devices while rapidly expanding upon receiving heat when a fire occurs.

The refractory foam material contained in the refractory foam unit 610 is a known material having a volume expansion force of approximately 300-400 times when subjected to high temperature due to fire or the like and is a material to be installed in a granular pipe such as an apartment. And the present invention is applied to the present invention.

In the present invention, the refractory foam unit 610 includes a rectangular case-shaped foam case 612 having one side opened, a cylindrical refractory foam material 614 loaded into the foam case 612, And a fixture 618 for fixing the foam case 612 to the inner wall surface of the enclosure 600. [

At this time, the fixing hole 618 is formed with a hook hole (HAL) whose upper and lower ends are bent in a substantially 'V' shape so as to elastically fix the foam case 612.

The upper surface and the lower surface of the foam case 612 on which the foam case 612 is assembled are formed with a hook groove GAL having a V-shaped groove in which the HAL of the fixture 618 is inserted.

The cover 616 is not completely fixed to the foam case 612 so that it can be easily exploded when the refractory foam 614 expands due to heat, .

To this end, a stepped surface is formed around the open end of the foam case 612, and a magnet MG is embedded in the stepped surface. One end of the cover 616 is connected to the open portion of the foam case 612 And a steel strip ST is embedded in the surface corresponding to the magnet MG.

In addition, a plurality of long holes (GON) are formed through the cover 616 to ensure that the refractory foam 614 is scattered while being exploded, and at the same time, the cover 616 is also scattered I can not help it.

With this configuration, replacement of the foam case 612 is convenient and it is possible to prevent the loss of the built-in parts mounted on the housing 600 at the time of a fire.

In addition, it is possible to provide a refractory structure that is safe from fire by applying a refractory liquid to the inner wall surface of the enclosure 600 to a certain thickness, and also to have antimicrobial properties so as to minimize the generation of mold on the inner wall surface of the enclosure 600 Lt; / RTI >

To this end, the refractory liquid was prepared by mixing 8 parts by weight of a powdery antimicrobial agent, 15 parts by weight of expanded graphite, 10 parts by weight of aluminum hydroxide; Ferric oxide: 20 parts by weight; Zirconium 5 parts by weight; 10 parts by weight of isopentane; 5 parts by weight of aromatic polyamine; 5 wt% of linseed oil, 5 wt% of white spirit, 5 wt% of naphthenic distillate, 70 wt% of fatty acid glycidyl esters, 10 wt% of phthalic anhydride 15 parts by weight of a first mixture mixed with 5% by weight of an oil resin and 5% by weight of an oil resin; Starch paste 10 parts by weight; 10 parts by weight of an acrylic monomer; 5 parts by weight of sodium silicate; 3 parts by weight of ethyl trimethylbenzoyl phenylphosphinate; And 4 parts by weight of an antimony tin compound.

Here, the polystyrene resin is excellent in heat resistance and impact resistance and is added to enhance compatibility.

The powdery antimicrobial agent is a substance that inhibits or inhibits the growth of bacteria, and is classified into an organic antimicrobial agent and an inorganic antimicrobial agent. The inorganic antimicrobial agent is made by substituting, supporting or coating nanoparticles of silver, zinc, copper, etc. which are antibacterial metals such as zeolite, calcium phosphate, zirconium phosphate, silica gel and the like, and the temporary antimicrobial activity is lower than the organic antimicrobial agent The human body is highly stable, resistant bacteria are not shown, and the duration of the antibacterial action is almost semi-permanent.

Particularly, since the inorganic antibacterial agent has to solve the problem of dispersibility when it is mixed with the resin, the range of application of the antibacterial agent according to the atomization of the particles and the technology of compounding with the polymer is expanding.

However, the inorganic antibacterial agent known in the art is disadvantageous in that the cost is increased because it must be prepared by substitution, support, or coating with nanoparticles.

Therefore, in the present invention, nickel and tungsten obtained as a by-product in the smelting of metal are mixed with water-tight materials (such as silica and fly ash) with ease and ease of processing, which; Nickel-zinc-tungsten mixed with activated carbon and ground to a predetermined particle size; A salt of an amine acid derivative is ground to a predetermined particle size; Those obtained by pulverizing salts of oxyquinoline derivatives to a predetermined particle size; The by-product obtained in the production of ethylene oxide is prepared by grinding a supported catalyst at a predetermined particle size; Silver ion-exchanged activated carbon is pulverized to a certain particle size and used as an inorganic antibacterial agent.

In addition, since the expanded graphite has a layered structure of graphite, when particles or small molecules are inserted between the layers and heat is applied, particles are expanded by several hundreds of times while being separated like an accordion, , Flame retardant EPS, and flame retardant urethane foam.

In addition, the aluminum hydroxide is added to prevent hydrophobicity of the resin and induce hydrophilization to increase the bonding force.

In addition, the ferric oxide is added in order to ensure weatherability and alkali resistance. If the amount of the ferric oxide is out of the above range, the grain size becomes coarse to deteriorate the mixing agility to deteriorate the moldability or deteriorate the weatherability and alkali resistance of the core material. .

The zirconium is added in order to increase the fire resistance and the flame retardancy by forming a protective coating made of an oxide or a nitrogen by bonding with oxygen in the air when a fire occurs.

In addition, the isopentane is added as a foaming agent.

In addition, the aromatic polyamines are added to promote curing.

In addition, the linseed oil constituting the first mixture is added for coloring as linseed oil, and the white oil is added to remove the cause of rust resistance against oxygen and moisture because of its emulsifying property, and naphthene distillation The liquid is a kind of solvent, and the fatty acid glycidyl ester, the phthalic anhydride and the oil resin are added to give flexibility.

Also, the starch paste is added for natural thickener and adhesive function, and the acrylic monomer is added for enhancing the stability at room temperature and enhancing the adhesive force to serve as a coating agent, and the sodium silicate is mainly referred to as Water Glass When heated due to fire or the like, the film reacts with metal ions contained in the composition of the present invention to form a film while being gelled, and the film has an increased incombustibility.

The ethyltrimethylbenzoylphenylphosphinate is added to suppress basic hydrolysis, and the antimony tin compound is added to protect the surface of the pavement surface through the heat block.

In order to confirm the refractory characteristics of the coating layer coated with the refractory liquid according to the present invention, the refractory solution having the above composition was coated on the steel plate to a thickness of 5 mm and then cured.

Then, the fire resistance test method, KS F2271, was used to measure the fire resistance.

Also, as a result of testing for antimicrobial activity by spraying the fungus strain, the number of the fungus strain decreased to 1/2 after 6 hours. It has also been confirmed that there is antibacterial activity.

In the present invention, in order to prevent deterioration of various mounting parts and to prevent malfunction by maintaining an adequate level of air freshness inside the housing 600, the intake unit 710 and the exhaust unit 710 of the form as shown in FIGS. 12 and 13, (720).

The intake unit 710 and the exhaust unit 720 have the same structure and are spaced apart from each other on the upper surface of the housing 600.

The exhaust unit 720 is connected to the opposite side of the intake unit 710 through the exhaust port 722 formed on one side of the intake unit 710, Only the point is configured to exhaust only.

The intake port 712 and the exhaust port 722 are provided with a replaceable filter (not shown).

Further, a voltage stabilizer (POW) for maintaining a constant voltage is further installed for stable operation of the fan incorporated in the intake unit 710 and the exhaust unit 720 and a plasma gun described later.

13, the intake unit 710 and the exhaust unit 720 are provided with a unit housing 730 and the exhaust port 722 or the intake port 730 is formed on one side or both sides of the unit housing 730. [ And a pair of fans 732 are installed in the unit housing 730. [

A lower case 736 is formed at the lower end of the unit housing 730 to have a size symmetrical with the unit housing 730 with respect to the partition plate 734, Plasma guns 750 are arranged at regular intervals.

A plurality of lower holes 742 are formed in the bottom surface of the lower case 736 and a plurality of upper holes 744 are formed in the partition plate 734, Lt; RTI ID = 0.0 > 744 < / RTI >

This is to increase the effect of the plasma treatment by maximizing the air flow.

Particularly, the inner wall surface of the lower case 736 and the lower end surface of the partition plate 734 are coated with an aluminum foil to enhance the reflection efficiency on the surface. This is to ensure that the plasma generated by the plasma gun 750 is released as well as possible.

Here, the discharge of the plasma may be directed toward the inside of the enclosure 600 or toward the atmosphere depending on the rotating direction of the fan 732. Even when discharged to the atmosphere, it is very useful because it is discharged in a plasma-treated state to prevent air contamination.

The plasma gun 750 includes a cylindrical glass 752 having a closed end and a rubber cap 754 for sealing the open end of the glass 752 and a glass 752 built in the glass 752, An anode 758 protruding into the glass 752 at the center of the rubber cap 754 and maintaining a constant gap with the cathode 756, Terminal 762 and a + terminal 764 connected to the cathode 756 and the anode 758, respectively.

Accordingly, when the air is sucked, the air sucked is highly dissociated due to the discharge between the cathode 756 and the anode 758, and plasma is generated and supplied to the inside of the enclosure 600. Thus, Keeps the air clean.

In addition, when exhausting, the exhaust gas is made inverse to the intake air, and the plasmaized exhaust air is discharged into the atmosphere and filtered as in intake.

As a result, the internal air of the housing 600 drops the internal heat due to a large quantity of anion effect in the filtered state and maintains a clean state, thereby preventing the deterioration of the mounted components and preventing malfunction, thereby prolonging the service life.
