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 and 113, a communication network 120, and a construction site safety management device 130 Includes some or all of ).

Here, "including some or all" means that some components such as the communication network 120 are omitted, so that the field devices 111 and 113 perform direct communication with the construction site safety management device 130 (eg, P2P communication). To perform, or to mean that some or all of the construction site safety management device 130 is integrated into a network device (eg, a wireless switching device) within the communication network 120 to be configured, etc., and a sufficient understanding of the invention Explain that it is all inclusive to help.

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, in the construction site safety management device 130, since the location of the worker is tracked, the buried location of the worker can be determined through the location tracking, but it is possible to provide safety information using a logo light method.

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.

The field devices 111 and 113 transmit data sensed by the field monitoring device 111 and the field monitoring device 111 to detect the work environment in the work space through the communication network 120, and the construction site safety management device 130 It includes a relay device 113 for transmission to. If the communication network 120 is a resource operated by a communication company, for example, the on-site devices 111 and 113 may be regarded as communication devices separately installed by a contractor at the construction site 97. The field monitoring device 111 includes a sensing device including a sensor for detecting temperature, humidity, gas leakage, and the like, and a photographing device such as a camera for photographing the inside of the work space. The site monitoring device 111 provides 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 device 113 may be composed of a first relay device installed inside the construction site and a second relay device installed outside the construction site. The first and second relay devices are Bluetooth, ZigBee, or Wi-Fi. While performing short-range wireless communication such as, the second relay device and the communication network 120 may perform communication such as TCP/IP or Real-Time Streaming Protocol (RTSP). Of course, since the first relay device and the second relay device can perform wired communication or optical communication, the embodiment of the present invention will not be particularly limited to the above communication method.

In the case of a photographing device, the photographed image can be usefully used to determine the progress of various tasks such as whether or not blasting is being performed, assuming that the construction site 97 is, for example, a tunnel closing site. will be. In addition, the relay device 113, in particular, the first relay device may perform short-range communication with the worn article 100 to acquire and transmit the location information of the worker. For example, if the relay device 113 performs Bluetooth communication with the wearing article 100 and transmits the device information and the signal strength value of the wearing article 100 together, the construction site safety management device 130 By calculating the distance based on the signal strength value or determining the direction as well, the location information of the worker may be determined based on the location information of the first relay device. In other words, since the installation position of the first relay device may be preset, the position may be determined by detecting a signal that changes in real time from workers based on this. For example, in the case where a plurality of first relay devices are installed, it is preferable that the relay device 113 at a place where the signal strength is high acquires and transmits a signal of an operator.

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 Internet networks such as cable networks and public telephone networks (PSTN), and wireless communication networks include CDMA, WCDMA, GSM, Evolved Packet Core (EPC), Long Term Evolution (LTE), and Wibro networks. It is meant to include. 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, femto or pico base stations are classified according to how many second relay devices 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 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 is a projection device that provides safety information in a visual manner such as a logo light (eg, a shadow method) or a laser beam from the wearable article 100 worn by workers at the construction site 97 ( 210). In order to provide safety information in a visual manner, the construction site safety management device 130 transmits safety information to the wearing article 100 to be provided in the order of an accident notification and an action guide according to a preset method. The safety information is selectively transmitted based on the location information or work content of workers. When there is safety information provided from the construction site safety management device 130, the worn article 100 outputs the corresponding safety information. 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 events or accidents occurring in the construction site 97, more precisely, in different work spaces, and appropriately delivers accident notifications and action guidelines to designated workers. can see.

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 In addition, based on the data provided by the sensing device or the photographing device, the work environment or work progress in the work space is monitored, and of course, an event or accident in the work space can be detected. 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 by the projection apparatus 210, and for example, a semiconductor device providing a beam may be controlled and irradiated in the form of a beam. Therefore, the above two methods may have slightly different data processing or 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 device 113 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 wearable article 100 through communication with the relay device 113, 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 device 113 can already be known by GPS tracking, etc., the relay device 113 measures the direction and distance through a gyro sensor, a speed sensor, a distance sensor, etc. of a portable terminal device such as a smartphone. By calculating the coordinate value based on the installation location of the worker, the location information of the worker is generated. 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 device 113 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 safety information notifying the occurrence of a gas accident has been transmitted from the construction site safety management device 130, the worn article 100 will notify the occurrence of a gas accident based on this in a visual method such as a logo light using a laser beam. And the safety information about the behavior guide that is matched to the accident notification and transmitted along with it can be output. As described above, the design method may be various, and thus, there will be no particular limitation to the above in the embodiment of the present invention. For example, the wearing article 100 may match and store safety information for accident notification and action instructions by itself, and output the stored information in order according to a control command from the construction site safety management device 130. will be.

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 transmits safety information from the construction site safety management device 130 received through the communication interface unit 300 to the safety information projection unit 330. If the control command is received as described above, the safety information projection unit 330 may be controlled to output the selected safety information by analyzing the control command and selecting appropriate safety information according to the analyzed content.

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 by a logo light method using a laser beam. This can facilitate the rescue of the rescuer.

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 using a laser beam as shown in FIG. 4. As shown in FIG. 4, the safety information projection unit 330 includes some or all of the beam data conversion unit 400 and the safety information beam irradiation unit 410, where "including some or all" means the above meaning and same. The beam data conversion unit 400 may control the safety information beam irradiation unit 410 according to an information value (eg, binary 16-bit information) of safety information provided from the control unit 310. For example, the beam data conversion unit 400 may be composed of switching elements arranged in a matrix form, and the control unit 310 is a path of a voltage provided from the power supply unit 320 to express the received safety information. Is to be provided to the safety information beam irradiation unit 410 by opening through the control of the switching device. The safety information beam irradiation unit 410 operates according to the beam data conversion unit 400 to display safety information to the outside in a logo light method, and may include a'semiconductor laser' or a laser semiconductor device for this purpose. Since each of the laser semiconductor elements arranged and formed in the form of an array can constitute a dot for realizing safety information, the construction site safety management device 130 is controlled by controlling each semiconductor element constituting the dot. The safety information received from can be displayed on the floor or wall of the construction site.

More specifically, the safety information beam irradiation unit 410 irradiates a laser beam to the outside of each of the semiconductor devices, just as each pixel pixel implements an image in the display panel. Accordingly, the voltage of the power supply unit 320 is supplied to the safety information beam irradiation unit 410 according to a method selected (or controlled) by the beam data conversion unit 400, and the semiconductor device operates by the supplied voltage to generate the laser beam. It radiates to the outside. It can be seen that a plurality of laser semiconductor devices operate almost simultaneously, and a laser beam corresponding to the received safety information is irradiated on the wall. Since laser semiconductor devices arranged in a matrix form can express points, lines, planes, etc., various contents of safety information can be realized.

Safety information for notifying the occurrence of an accident or action guidelines at the construction site 97 may have different operating methods depending on the projection apparatus 210 manufactured in various forms. In the embodiment of the present invention, a method of using a semiconductor laser to miniaturize the projection device 210 is illustrated, but of course, safety information designed on a film or glass substrate located on the front side such as a beam projector is arranged on the rear side Since it is possible to project it on the wall or floor surface of the construction site 97 in the form of a shadow through, the embodiment of the present invention will not be particularly limited to any one form.

Meanwhile, the storage unit 340 may process various types of information or data processed by the control unit 310 and may pre-store the information in the form of a lookup table as described above. Data stored in the storage unit 340 may be output at the request of the control unit 310. For example, assuming that the safety information is received as binary 16-bit information, information on how to control the beam data conversion unit 400 using the 16-bit information is matched and stored in a lookup table. I can. Accordingly, the controller 310 may control, for example, a switching device of the beam data conversion unit 400 based on the corresponding information.

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 field monitoring device 111 via the communication network 120 and the relay device 113. 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, for example, sensing data or a photographed image provided from the field monitoring device 111 and transmits it to the control unit 510. In addition, the communication interface unit 500 provides safety information when it is determined that it is necessary to provide safety information to a specific worker as a result of monitoring the construction site through sensing data or photographed images in the construction site safety management device 130. . 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, the control unit 510 provides safety information entirely or selectively from the safety information visualization processing unit 520 to the workers at the construction site 97, and controls the communication interface unit 500 so that the safety information is transmitted to the construction site ( 97) to be provided in the wearable article 100. When transmitting the safety information, the control unit 510 transmits address information or device identification information of the wearing article 100 together, so that the safety information may be provided to the wearing article 100 based on this.

Meanwhile, 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, the safety information visualization processing unit 520 not only notifies a certain fact when providing safety information, but also transmits a notification of the occurrence of a specific accident and an action guide at the same time. 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, in case of fire or collapse, safety information is provided to all workers in a way such as logo light using a laser beam, that is, accident notification and action instructions are provided so that rapid response can be achieved. Accident notification and action instructions can be given to relevant workers to evacuate certain workers of concern or to stop welding or other work. 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.

6 is a flow chart showing a driving process of the construction site safety management device shown in FIG.

For convenience of explanation, referring to FIG. 6 together with FIG. 1, the construction site safety management apparatus 130 according to an embodiment of the present invention is used to provide safety information in a laser beam method in a wearable article worn by a construction site worker. It stores a plurality of safety information (S600). Here, the stored information may match and store the first safety information for an accident notification and the second safety information indicating an action guideline for coping with the accident that has occurred.

In addition, the construction site safety management device 130 may control the safety information selected based on the location information of the worker at the construction site among a plurality of stored safety information to be output in a laser beam method from the wearing article 100. (S610). To this end, the construction site safety management device 130 is also possible to select and use the safety information previously stored in the worn article 100 by simply transmitting a control command in addition to transmitting the selected safety information. Therefore, it will not be specifically limited to the above.

For example, the construction site safety management device 130 provides safety information for notification of accidents such as gas accidents, collapse accidents, and fires, which are worn by workers at the construction site 97, more precisely, based on location information. When provided as a wearable article 100, the projection device 210 receives the safety information and displays it to the outside by a logo light method using a laser beam or the like. Of course, in this process, the safety information may be transmitted to the projection apparatus 210 by further referencing the work content of workers or the work environment of the work space, rather than simply using the location information.

In addition to the above, the details related to the other construction site safety management device 130 have been sufficiently described above, so the contents will be substituted.
