1 is a view showing a construction site safety management system according to an embodiment of the present invention, Figure 2 is a view showing an example of the hard hat of Figure 1 as a worn article.

As shown in Figure 1, the construction site safety management system 90 according to an embodiment of the present invention is a wearable article 100, field devices 111, 113, 115, 117, communication network 120 and construction site safety Includes some or all of the management device 130.

Here, "including some or all" means that some components such as the communication network 120 are omitted, so that the on-site devices 111, 113, 115, 117 and the construction site safety management device 130 are directly communicated (eg: P2P communication), or a part or all of the construction site safety management device 130 is integrated into a network device (for example, a wireless switching device) in the communication network 120 to be configured. It is explained as including all in order to help a sufficient understanding of.

Wearing article 100 includes a hard hat 200 of FIG. 2, a safety suit, safety shoes, or a waist belt, etc. worn by a worker at the construction site 97. Here, the hard hat 200 or safety clothes and safety shoes may be referred to as work hats, work clothes and work shoes. Wearable article 100 according to an embodiment of the present invention is a safety information providing device that provides safety information to the outside according to a control command from the construction site safety management device 130 in a manner such as logo light or laser beam, for example, It includes the projection device 210 of 2. 2 shows that the projection device 210 is configured on the hard hat 200, but the projection device 210 according to the embodiment of the present invention is attached to a wearing article 100 such as a hard hat 200 or safety clothing. It is desirable to increase the effect of information transmission by providing safety information in front of the operator, that is, in front of the operator's actions, and to always face the operator's gaze. By transmitting safety information by a visual method, it can be very easy when it is not easy to communicate accident notifications and action instructions due to noise from the construction site 97. In addition, even in an emergency emergency such as an actual collapse accident, it is possible to facilitate the rescue of a worker by continuously exposing light from the projection apparatus 210 to the outside through a constant power supply. Of course, since the construction site safety management device 130 tracks the location of the worker, it is possible to determine the buried location of the worker through the location tracking, but it will be possible to provide safety information in a logo light method in parallel.

Wearing article 100 is operated by the remote control of the construction site safety management device (130). For example, the wearing article 100 may selectively receive a control command so that safety information is provided according to the location information according to the location tracking through the location tracking of the worker. For example, when it is determined that workers in area A should be evacuated, when the work is being divided into area A and area B at the construction site 97, the safety management device 130 at the construction site is the equipment worn by workers in area A. Safety information should be provided at (100), but safety information indicating accident notification and action guidelines should be provided sequentially by a visual method such as a logo light method. Of course, it may be possible to provide it to workers in the entire area, but it is desirable to selectively provide it to prevent confusion of the construction site 97 and to gain trust in safety information from workers. Even if there is a need to transmit safety information to all areas, confusion that may occur during evacuation can be prevented in advance by changing the transmission time of area A and area B to prevent confusion within the construction site (97). have. For example, by judging the degree of risk in each area, workers in areas with high risk can be evacuated first, and when evacuation is completed, workers in areas with low risk can be evacuated.

In addition, the wearing article 100 may selectively receive a control command according to the work content even in the case of workers working in the same area. In general, when the work is performed by forming a team, the contents of the work of the workers before being put into the work may be provided in advance to the construction site safety management device 130 and stored in the DB 130a. Of course, it may be possible to automatically determine the work content through location tracking. For example, if it is determined that the occurrence of an accident in area A affects workers in a specific work group in area B, safety information is provided only in the articles 100 worn by specific workers according to the work content, even in the same area. It is to be. For example, by providing safety information from the wearable article 100 of workers in which welding work is performed, an accident notification of occurrence of a gas accident in an adjacent area and an action instruction of stopping welding may be provided as safety information. In FIG. 1, it shows that an accident notification phrase 101 that an accident has occurred is provided as safety information in the article 100 worn by a specific worker.

Field devices (111, 113, 115, 117) are the work environment detection devices (111, 113) for detecting the work environment in the work space and the data sensed by the detection devices (111, 113) to an external communication network (120). ), and a relay device (115, 117) for transmission to the construction site safety management device (130). If the communication network 120 is a resource operated by a communication company, for example, the on-site devices 111, 113, 115, and 117 may be regarded as communication devices separately installed by a contractor at the construction site 97. The sensing devices 111 and 113 include a sensing device 111 including a sensor for detecting temperature, humidity, gas leakage, and the like, and a photographing device 113 such as a camera for photographing the inside of the work space. The sensing devices 111 and 113 provide data for monitoring the work environment in the work space and the movement of workers to the construction site safety management device 130. On the other hand, the relay devices 115 and 117 may be composed of a first relay device 115 installed inside the construction site and a second relay device 117 installed outside the construction site. The first relay device 115 And the second relay device 117 performs short-range wireless communication such as Bluetooth, Zigbee, and Wi-Fi, but the second relay device 117 and the communication network 120 are configured such as TCP/IP or Real-Time Streaming Protocol (RTSP). Communication can be performed. Of course, since the first relay device 115 and the second relay device 117 can perform wired communication and optical communication, the embodiment of the present invention will not be particularly limited to the above communication method.

In the case of the photographing device 113, assuming that the construction site 97 is the tunnel closing site as shown in FIG. 1, various tasks such as whether blasting is being performed and the progress of the work are determined. It will be useful to do. In addition, the relay devices 115 and 117, in particular, the first relay device 115 may perform short-range communication with the worn article 100 to obtain and transmit the location information of the worker. For example, if the relay devices 115 and 117 perform Bluetooth communication with the wearing article 100 and transmit the device information and the signal strength value of the wearing article 100 together, the construction site safety management device 130 ) May determine the location information of the worker based on the location information of the first relay device 115 by calculating the distance based on the signal strength value or determining the direction together. In other words, since the installation position of the first relay device 115 may be preset, the position may be determined by detecting a signal that changes in real time from workers based on this. For example, when a plurality of first relay devices 115 are installed as shown in FIG. 1, it is preferable that the relay devices 115 and 117 at places where the signal strength is high acquire and transmit a signal of a worker.

The communication network 120 includes all wired and wireless communication networks. For example, as the communication network 120, a wired or wireless Internet network may be used or interlocked. Here, the wired network includes an Internet network such as a cable network or a public telephone network (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), Wibro network, and 5G. It is meant to include communication networks and the like. Of course, the communication network 120 according to the embodiment of the present invention is not limited thereto, and may be used as an access network for a next-generation mobile communication system to be implemented in the future, for example, a cloud computing network or a 5G network under a cloud computing environment. For example, when the communication network 120 is a wired communication network, the access point in the communication network 120 can be connected to the switching center of the telephone office, but in the case of a wireless communication network, data is accessed by accessing SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company. Alternatively, data can be processed by accessing various repeaters such as BTS (Base Station Transmission), NodeB, and e-NodeB.

The communication network 120 may include an access point. The access point includes a small base station such as a femto or pico base station that is frequently installed in a building. Of course, the access point may be a resource of a carrier. Here, the femto or pico base station is classified according to how many second relay devices 117 or smart devices (eg, smart phones, etc.) of workers can be connected according to the classification of small base stations. Of course, the access point includes a second relay device 117 or a short-range communication module for performing short-range communication such as ZigBee and Wi-Fi with smart devices (eg, smart phones) of workers. The access point can use TCP/IP or RTSP for wireless communication. Here, short-range communication is performed in various standards such as RF (Radio Frequency) such as Bluetooth, Zigbee, Infrared (IrDA), UHF (Ultra High Frequency) and VHF (Very High Frequency), and ultra wideband communication (UWB), in addition to Wi-Fi. I can. Accordingly, the access point extracts the location of the data packet, designates the best communication path for the extracted location, and transmits the data packet to the next device, for example, the construction site safety management device 130 along the designated communication path. The access point can share several lines in a general network environment, and includes, for example, a router, a repeater, and a repeater.

The construction site safety management device 130 communicates with the projection device 210 that provides safety information in a visual manner such as a logo light or a laser beam from the wearable article 100 worn by workers at the construction site 97. do. In order to provide safety information in a visual manner, the construction site safety management device 130 transmits a control command to the wearing article 100 so that safety information is provided in the order of accident notification and action instructions according to a preset method, and , The control command transmitted at this time is selectively transmitted based on the location information or work details of the workers. When there is a control command provided from the construction site safety management device 130, the worn article 100 operates according to the corresponding control command. For example, an accident notification can notify the occurrence of various types of accidents. For example, there may be a gas accident or a collapse accident, and there may be a sudden injury to a worker. Therefore, the guideline for action accordingly may be different. Of course, the guidelines for action depend on the content of the accident. The construction site safety management device 130 monitors various incidents or accidents occurring in the construction site 97, more precisely, in different work spaces, and appropriately transmits accident notifications and action guidelines to designated workers. It can be viewed as controlling.

To this end, the construction site safety management device 130 according to an embodiment of the present invention generates location information of workers in real time based on a communication signal provided by the wearable article 100 worn by workers at the construction site 97 Also, based on the data provided by the sensing device 111 or the photographing device 113, the work environment or work progress in the work space is monitored, and of course, an event or accident in the work space is detected by this. can do. In addition, when the work is performed according to the daily work schedule before being put into the construction site 97, the construction site safety management device 130 may check the work contents based on the corresponding schedule information. The construction site safety management device 130 operates so that safety information can be appropriately transmitted to specific workers based on this integrated information.

Of course, in addition to the construction site safety management device 130, when an accident occurs in area A of the construction site 97, it transmits safety information to specific (or accident-related) workers in adjacent area B and Whether the safety information for notifications and action instructions is to be delivered may be periodically updated and stored in the DB 130a. For example, when a worker who composes a team member suddenly injuries in a work space where a team is formed, safety information is delivered to the team leader in a visual way. It is able to notify the accident of'team member injury accident' and provide the action guideline of'emergency evacuation required'. If the logo light method is to select the safety information previously stored in the projection device 210 according to the instruction of the construction site safety management device 130 so that the safety information is displayed to the outside, the laser beam method is a construction site safety management device. The safety information provided by 130 may be converted into beam data in the projection apparatus 210 and may be irradiated in the form of a beam. Therefore, the above two methods may have slightly different data processing and operation.

The communication or operation process between the construction site safety management device 130 and the wearable article 100 of the construction site 97 according to an embodiment of the present invention is a projection of a certain principle, that is, safety information in a visual manner. Since it may be changed in various ways depending on whether or not to be exposed to the outside and the intention of the system designer, the embodiment of the present invention will not be particularly limited to the above contents.

On the other hand, the construction site safety management device 130 always operates the projection device 210 of the worn article 100 in the event of an accident in which a worker is buried, such as a collapse accident, to provide safety information, more precisely, safety. By providing a light source for displaying information to the outside, rescuers can facilitate the rescue of workers. To this end, the construction site safety management device 130 is capable of controlling a system such as a logo light to operate at all times rather than selectively in a specific event or accident.

3 is a block diagram showing a detailed structure of the projection apparatus shown in FIG. 2, and FIG. 4 is a diagram illustrating a detailed structure of the safety information projection unit of FIG.

3, the projection apparatus 210 according to the embodiment of the present invention includes a communication interface unit 300, a control unit 310, a power supply unit 320, a safety information projection unit 330, and a storage unit 340. Includes some or all of ).

Here, "including some or all" means that some components such as the storage unit 340 are omitted, or some components such as the power supply unit 320 are integrated into other components such as the control unit 310 It is intended to mean something that can be configured, and will be described as including all in order to help a sufficient understanding of the invention.

The communication interface unit 300 communicates with the relay devices 115 and 117 or a portable terminal device (eg, a smartphone, etc.) possessed by workers. The communication interface unit 300 may provide information such as a device ID of the worn article 100 through communication with the relay devices 115 and 117, for example, through Bluetooth communication. Of course, as for the location information of the worker, it may be possible to transmit coordinate information generated in the portable terminal device of the worker. For example, since the installation location of the relay devices 115 and 117 can already be known by GPS tracking, the direction and distance are measured through a gyro sensor, a speed sensor, a distance sensor, etc. of a portable terminal device such as a smartphone. 115, 117) is to generate the location information of the operator by calculating the coordinate value based on the installation location. Since such an operation can be implemented in any number within the projection device 210, it will not be specifically limited to the portable terminal device.

The communication interface unit 300 receives a control command provided by the construction site safety management device 130 through the relay devices 115 and 117 and transmits it to the control unit 310. The control command is the control that the construction site safety management device 130 monitors the positions of workers working in each work space of the construction site 97, the progress of construction, and the work environment, and transmits them to the workers accordingly. It is a signal, and it can be seen as a control signal that instructs workers to be provided with safety information respectively. This may be determined according to a communication protocol of the wearable article 100 and the construction site safety management device 130 or a policy of a system designer.

For example, if the construction site safety management device 130 transmits binary 4-bit information as '0001' as a control command notifying the occurrence of a gas accident, the wearing article 100 sends an accident notification that a gas accident has occurred based on this. It is understood as a command to output in a visual way such as a logo light, and operates as above, and safety information on the action guide matching the accident notification can also be output. As described above, the design method may be various, and thus the contents thereof will not be particularly limited in the embodiments of the present invention.

The control unit 310 controls the overall operation of the communication interface unit 300, the power supply unit 320, the safety information projection unit 330, and the storage unit 340 constituting the projection apparatus 210. For example, the control unit 310 controls the safety information projection unit 330 according to a control command from the construction site safety management device 130 received through the communication interface unit 300. As above, when a control command is received, the control command is analyzed and the safety information projection unit 330 is controlled according to the analyzed content. For example, when a control command related to'gas accident occurrence' is received, the control unit 310 refers to the information stored in the storage unit 340 in the form of a lookup table (LUT) and displays the safety information projection unit 330 according thereto. You decide how to do it, and you run it. For example, if the safety information projection unit 330 is a system capable of outputting safety information to the outside by rotating the safety information by a motor, etc., the control value for controlling the motor will be matched to the received control command in the lookup table. . In other words, when the control command is received, the control unit 310 finds the control value of the motor matching the received control command in the lookup table, and controls the motor accordingly, and displays safety information, that is, the phrase of the occurrence of a gas accident, in the safety information projection unit ( It is to be provided to the outside through 330). Of course, this assumes that safety information is provided in the logo light method. Therefore, in the case of providing safety information in the form of a laser beam, the operation may be slightly different, but the contents are not significantly different in controlling the safety information projection unit 330 according to the received control command.

In addition, the control unit 310 may further include a flash (or flash) when the projection device 210 is attached to the hard hat 200 to constitute the wearable article 100 as shown in FIG. 2, in this case At the same time, an operation such as turning off the flash and operating the projection apparatus 210 may be performed in parallel. To this end, the control unit 310 may cut off the power supplied to the flash from the power supply unit 320, for example. For example, when a collapse accident occurs, the control unit 310 constantly provides the power of the power supply unit 320 to the safety information projection unit 330 at the request of the construction site safety management device 130 to provide a flash at all times. It can be turned on or the safety information phrase in a specific state can be always output to the outside in a logo light method. This can facilitate the rescue of the rescuer.

As will be described later, the safety information projection unit 330 may be configured in a logo light method requiring a light source as shown in FIG. 4. Accordingly, the control unit 310 may provide power necessary to provide a light source through the power supply unit 320. The light source is preferably an eco-friendly lamp, and may include an LED module for this purpose. The LED module can provide white light by using white LEDs, but it is possible to output white light by mixing red (R), green (G), and blue (B) LEDs, and the control unit 310 is a power supply unit ( 320) can be seen to provide power to drive the corresponding LED module.

The power supply unit 320 may include a battery that generates DC power. In this case, for example, the construction site safety management device 130 may also monitor the remaining amount of the battery of the projection device 210 to instruct battery replacement. In fact, visually outputting the safety information from the safety information projection unit 330 is intended to further enhance the safety of the operator, and thus, measuring the remaining amount of the battery may be very important in this respect. Accordingly, the power supply unit 320 may be configured such that AAA batteries or mercury batteries of a circular type are input, so that the operator can perform periodic replacement.

The safety information projection unit 330 may be configured in a logo light method as shown in FIG. 4. The logo light method corresponds to a system that provides safety information located on the front side such as a beam projector to the outside through a light source located on the rear side. The safety information projection unit 330 may include a lens unit 400, a safety information display unit 410, and a light source unit 420 as shown in FIG. 4. The lens unit 400 allows the safety information displayed on the safety information display unit 410 to be displayed at a predetermined distance by the light source of the light source unit 420. The lens of the lens unit 400 may be configured by using various lenses such as a convex lens, a concave lens, a flat lens, and a curved lens, or by appropriately combining them.

The safety information display unit 410 includes a plurality of glass substrates on which safety information is printed or formed respectively on the glass substrate, and the control unit 310 rotates the glass substrate by a motor so that desired safety information can be displayed to the outside. can do. Of course, the safety information display unit 410 is configured in the same manner as the transparent display so that the light source can be transmitted through the light source unit 420, and safety information is displayed on the transparent display, so that the image is implemented in the image display device. It may be possible to operate as many times as you like. In other words, when safety information for accident notification and safety information indicating action instructions are sequentially displayed on the transparent display, they are provided to the outside through the light source at the rear. Here, in the transparent display, the display panel itself is red (R). Since it is composed of transparent LEDs of green (G) and blue (B), it can be configured without difficulty. Of course, even if this is not the case, red (R), green (G), and blue (B) color filters are configured on the front side, and red (R), green (G), and blue (B) backlight LED modules are configured on the rear side. Since it may be possible to implement the safety information in the logo light method through this configuration, the embodiment of the present invention will not be particularly limited to any one method.

That is, in the embodiment of the present invention, the safety information projection unit 330 rotates a film or substrate (glass, quartz substrate) as shown in FIG. 4 to provide preprinted or formed safety information, and safety information It can be considered that it includes a text display method that can provide safety information by allowing the image to be displayed on the screen in the same manner as the image is implemented.

The storage unit 340 may process various types of information or data processed by the control unit 310 and may pre-store information in the form of a lookup table as mentioned above. Data stored in the storage unit 340 may be output at the request of the control unit 310.

5 is a block diagram showing the detailed structure of the construction site safety management device of FIG.

As shown in Figure 5, the construction site safety management device 130 according to an embodiment of the present invention is a communication interface unit 500, the control unit 510, the safety information visualization processing unit 520 and the storage unit 530 Includes some or all.

Here, "including some or all" means that some components such as the storage unit 530 are omitted, or components such as the safety information visualization processing unit 520 are applied to other components such as the control unit 510. It is intended to mean something that can be integrated and configured, and will be described as including all in order to help a sufficient understanding of the invention.

The communication interface unit 500 communicates with the worker's worn article 100 or the sensing devices 111 and 113 via the communication network 120 and the relay devices 115 and 117. In the process of performing communication, the communication interface unit 500 may perform operations such as modulation/demodulation, encoding/decoding, and muxing/demuxing, but this is obvious to those skilled in the art, and thus further description will be omitted.

The communication interface unit 500 receives a sensing signal, such as sensing data or a photographed image, provided from the sensing devices 111 and 113 and transmits the received sensing data to the controller 510. In addition, the communication interface unit 500 monitors the construction site through sensing data or photographed images from the construction site safety management device 130 and provides safety information provided when it is determined that it is necessary to provide safety information to a specific worker. Receive. Accordingly, the worker recognizes the contents of the accident occurring at the construction site 97 and, if necessary, allows the worker to respond quickly. Above all, safety information can be visually displayed on the floor or wall (surface) of the construction site so that workers can quickly recognize and cope with the characteristics of the construction site 97.

The control unit 510 is in charge of overall control operations of the communication interface unit 500, the safety information visualization processing unit 520, and the storage unit 530 constituting the construction site safety management device 130. When the sensing data or photographed image of the construction site 97 is provided through the communication interface unit 500, it is provided to the safety information visualization processing unit 520 so that the construction site 97 is monitored. In addition, various data generated for monitoring may be stored in the DB 130a, and the data stored in the DB 130a may be generated in a preset format and provided when requested by a construction site supervisor or manager. Further, when there is a command from the safety information visualization processing unit 520 to provide safety information in whole or selectively to workers at the construction site 97, the control unit 510 may activate the communication interface unit 500 according to the corresponding command. Control so that a control command is provided to the wearing article 100 of the construction site 97. When transmitting the control command, the controller 510 transmits address information or device identification information of the wearing article 100 together, so that a control command may be provided to the wearing article 100 based on this.

As another embodiment of the present invention, the control unit 510 of FIG. 5 may be configured to include a CPU and a memory. At this time, the CPU and the memory may be formed into one chip. The CPU may include a control circuit, an operation unit (ALU), an instruction analysis unit, a registry, and the like, and the memory may include RAM. The control circuit is in charge of the control operation, the operation unit may perform binary bit operation, and the instruction analysis unit may determine what operation to perform by interpreting the instruction of machine language. The registry is concerned with software data storage. Accordingly, the control circuit will be able to quickly increase the computational processing speed by copying the program stored in the safety information visualization processing unit 520 when the construction site safety management device 130 is initially driven, loading it into the memory, and executing it. .

The safety information visualization processing unit 520 analyzes the data provided by the construction site 97 to monitor the construction site 97, and as a result of monitoring, the location information or work of workers when there is an accident or when there is a concern about the occurrence of an accident. Based on the content, the safety information is selectively provided to the worker so that it can be responded quickly. Above all, when providing safety information, the safety information visualization processing unit 520 does not just notify a certain fact when transmitting a control command so that safety information is provided to the operator, but acts at the same time as notifying the occurrence of a specific accident. Send instructions as well. Of course, such safety information can be based on the location information of the worker, and further, the work content. Through this, it is possible to reduce the fatigue caused by safety information by preventing unnecessary transmission of safety information to neighboring workers who are not affected by the accident.

In addition, when transmitting the safety information, the safety information visualization processing unit 520 may determine whether or not there is a risk based on work details or the like. For example, when an accident occurs in Area A, workers in Area A can be notified of the occurrence of the accident and can be promptly responded, but it is determined whether it may affect the adjacent area, Area B or Area C. It is also appropriately transmitting safety information to the adjacent area. For example, if there is a gas accident in area A, and if there is welding work as a result of checking the work details in the adjacent area, it is likely that there is a lot of room for impact. It can be seen that the safety information visualization processing unit 520 performs an analysis on such a relationship in real time. In addition, for example, in the case of an injury to a specific worker, safety information can be provided from the wearable equipment 100 of the team leader overseeing the work in the area, but it will be judged that it is difficult to respond quickly as a result of tracking the location of the team leader. In this case, it can be delivered to the next ranked team member according to the designated policy, or it can be operated so that the emergency vehicle can be automatically queued together.

The safety information visualization processing unit 520 performs an operation related to allowing the safety information to be provided through a logo light or a laser beam method through the wearable article 100. Accordingly, a communication protocol for performing communication with the projection apparatus 210 of FIG. 2 is set and may be properly operated accordingly. For example, the safety information visualization processing unit 520 configures the safety information as binary 4-bit or 8-bit information when designing the system, and facilitates communication with the wearing device 210 through this. For example, as binary 4-bit information, gas accidents are specified in the same way as '0001', fires are '0010', and collapses are defined in the same way as '0011', and accordingly, action guidelines are matched and set accordingly. It is to ensure that rapid response occurs. For example, in case of fire or collapse, safety information is provided to all workers in a way such as logo light, that is, accident notifications and action guidelines are provided to enable prompt response, and in the case of gas accidents, specific workers who are concerned about damage The accident notification and action instructions can be given to related workers to evacuate or stop working such as welding. Since workers can see safety information, that is, safety characters displayed on the floor or wall of the site from the projection device 210 of the wearing article 100 that they wear, a quick response to the situation is achieved.

Furthermore, the safety information visualization processing unit 520 may predict an event or accident that may occur at the construction site 97 by mounting an artificial intelligence (AI) program and provide safety information in the form of predicted information. In other words, if there is a history of incidents or accidents occurring under the same conditions at other construction sites, this is to be notified. In addition, by periodically monitoring the behavior patterns of workers, it is possible to provide relevant safety information to the workers in case of a need for attention in the case of a drowsy worker. In this way, the safety information visualization processing unit 520 may perform a deep learning operation based on data received at a construction site and perform various operations for the safety of a worker using the result of the deep learning. Above all, in the embodiment of the present invention, the safety information is output from the most optimal worker's worn article 100 based on the location information or work content of workers at the construction site, and furthermore, on the floor or wall of the site. It is desirable to use an AI program to ensure that safety information is displayed visually so that a quick response can be made.

The storage unit 530 processes various information or data processed under the control of the control unit 510, and the control unit 510 sequentially stores sensing data or photographed images provided from the construction site 97 to the storage unit 530. After saving as, it can be called in order and provided to the safety information visualization processing unit 520. Of course, if there is data to which priority is given in the process of objection, the corresponding data may be called first and provided to the safety information visualization processing unit 520. According to an embodiment of the present invention, information may mean a simple control command, in other words, a request signal or a response signal, and the data is red (R) and green (G) constituting pixels in a photographed image. , Blue (B) pixel data may be meant, but in the exemplary embodiment of the present invention, the meaning is not particularly limited.
