Description

Portable Apparatus for Safety Management in Construction Site and Driving Method

The present invention relates to a portable safety management device used in a construction site and a method of driving the device, and more particularly, it can be easily installed at a desired location using a portable safety management device at a construction site such as a tunnel construction. It relates to a portable safety management device used in a construction site that performs safety management operations on the site, and a method of driving the device.

As society develops and becomes industrialized, safety accidents occur frequently not only in industrial facilities but also in social facilities as a whole, for workers who work in harmful working environments. Typical examples are the inside of a manhole for the work of electrical equipment or other pipeline facilities, storage tanks such as underground storage tanks and gas filling stations, water collecting wells, interior painting workshops, or other workshops in underground facilities where ventilation is difficult. Workers working inside these hazardous workplaces are often injured due to gas poisoning, breathing difficulties, suffocation, or explosion accidents due to the generation of various harmful gases such as ozone, nitrogen dioxide, sulfur dioxide, ammonia, and hydrochloric acid. Although various risk factors are scattered in the field, such as fire and explosion accidents at construction sites, and human casualties due to the release of harmful gases from the tunnel, it is impossible to manage a large site with limited safety management personnel in real time, and also dangerous processes occur simultaneously. However, safety accidents, both large and small, continue to occur frequently in the field because customized safety management is not carried out at each site.

In this regard, in the related art, safety management in the field is sought by monitoring some harmful gas sensors or monitoring the location of workers, but the reality is that safety management is extremely limited or remains in follow-up management.

In addition, in the prior art, since various communication equipment is fixed and used at the construction site, it is not only inconvenient to remove and reinstall the fixed equipment according to the progress of the construction, but also when an accident occurs and communication is cut off from the construction site. There is also a problem that the follow-up response does not proceed smoothly.

Furthermore, in the conventional safety management device, each facility must be separately fixed and installed, and electricity must be connected to each, so the installation is complicated. In addition, there are many difficulties in maintenance and management, such as dismantling installed devices or re-installing fixed devices that need to be moved one by one depending on the construction site.

In addition, the conventional safety management device not only needs to connect a separate electric wire, but also does not include a black box function.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a view showing a safety management system of a construction site according to an embodiment of the present invention.

As shown in FIG. 1 , the safety management system 90 of a construction site according to an embodiment of the present invention includes a portable safety management device 100 , a communication network 110 , a construction site control device 120 , and a manager terminal device. some or all of (130).

Here, "including some or all" means that some components such as the communication network 110 are omitted, so that the portable safety management device 100 and the construction site control device 120 directly communicate (eg, P2P communication). It means that some or all of the components constituting the construction site control device 120 may be integrated into a network device (eg, a wireless exchange device, etc.) constituting the communication network 110 and configured, etc., In order to help a sufficient understanding of the invention, it is described as including all.

The portable safety management device 100 has a miniaturized form. The portable safety management device 100 is made small and can be easily installed at a desired location at a construction site, for example, and may include a battery charged with solar heat and a battery charged with electricity. In addition, the portable safety management device 100 may use a commercially available general battery (eg, AAA, mercury battery, etc.) as a battery. While the portable safety management device 100 is installed at a construction site, when a movement of a person or an object is detected through infrared or the like, that is, an event is detected, an image is recorded. When the storage space is insufficient due to the occurrence of many events, the black box function can be performed by distributing the captured images to the adjacent portable safety management device 100 and improving the data loss problem despite the occurrence of the event. have. For example, when the portable safety management device 100 is buried due to a tunnel collapse accident, it will be possible to flexibly cope with the accident by transmitting and storing the captured image to the surrounding portable safety management device 100 .

More specifically, the portable safety management device 100 according to an embodiment of the present invention may be installed at a predetermined interval at a construction site, and a plurality of infrared sensors and micro-cameras such as pinhole cameras are built-in to 360 degrees from one direction. The event image is stored for the whole, and the installation location of the portable safety management device 100 is checked through the global positioning system (GPS) to enable replacement and installation when the battery is insufficient, and to control the movement of the operator including the beacon receiver. It can be checked, and it can receive the broadcast from the control room and output it to the speaker. In addition, it is possible to prevent accidents so that work conflicts between workers do not occur through the speaker, and to warn through a notification or the like if there is a worker who should not be in the relevant area among the workers received from the beacon receiver.

The portable safety management device 100 according to an embodiment of the present invention may have a main body in a rectangular or circular (tubular) shape, and may include various types of fixing parts or installation parts for freely installing at a construction site. have. When the fixing part is fixed to the ground, it may have a sharp bar shape like the fixing part of a sign, but when it is installed on a wall, it can have various shapes for installing the portable safety management device 100 on the wall. have. In short, it may have an adsorption form that adsorbs to the wall surface. Of course, the embodiment of the present invention will not be particularly limited to any one installation structure.

A plurality of sensors and a plurality of small cameras may be mounted on the main body constituting the portable safety management device 100 . It is desirable to allow movement and shooting in all directions of 360 degrees based on the designated direction. For example, each sensor may be provided in an area corresponding to four directions of east, west, south, north, and south, and a small camera may be mounted around it. Therefore, when a motion or various situations are detected by the sensor, a small camera that takes a picture in a specific direction is activated through a sensing signal to take a picture. In other words, even in the case of a small camera, when small cameras are installed in each of the four directions of east, west, north, and south, shooting is performed when a specific situation occurs at the construction site or work site, and the camera is operated only in a specific situation, so for example, the construction site control system ( 120) will be able to increase the control efficiency.

In other words, the portable safety management device 100 can selectively operate a plurality of small cameras in a specific situation, and when one small camera is typically operated for shooting a specified direction, the two cameras are operated at the same time. In this case, it can be assumed that three cameras are simultaneously operated, and furthermore, four cameras are operated simultaneously. Of course, each camera may be operated only during a specific time period. This operation may be performed differently depending on the position in which the portable safety management device 100 is again installed. For example, if the portable safety management device 100 is installed in a designated location and power is supplied, all cameras are turned on during initial operation to photograph the surrounding situation, and more precisely, after performing a scan operation, it is possible to operate You can set the camera. For example, when the portable safety management device 100 is installed on the wall, it is preferable not to operate the camera facing the wall. As described above, it can be seen that the operation of the small camera is controlled based on the installed position during the initial operation.

The number of small cameras installed in the portable safety management device 100 may be determined according to an angle of view taken by a lens of the camera, that is, an angle or range taken. For example, if each camera has an angle of view of 45 degrees, four small cameras can be mounted to take pictures in all directions. Angle of view can be more precisely defined as the field of view of a scene captured by a camera. A wide-angle lens has a wide angle of view and a telephoto lens has a narrow angle of view. A typical lens has a field of view ranging from 15 to 60 degrees. Since human vision is about 50 degrees, a standard lens is 44 to 55 degrees, a wide-angle lens is 60 to 80 degrees, a telephoto lens is 30 degrees or less, and a fisheye lens is about 180 degrees.

Above all, the portable safety management device 100 according to an embodiment of the present invention can apply a pinhole camera as a miniature camera. A pinhole camera is a pinhole-only camera without a lens. It uses the basic principle of a camera obscura, which means "dark room", and replaces it with a photosensitive plate or film instead of a focal plate that simulates a picture. A very small hole is drilled on one side to allow light to pass through, and a film is placed on the back of the camera to form an image, and the appropriate pinhole size is determined by diffraction and the amount of light. distance is determined. This is the principle of the pinhole camera.

As one of the easiest ways to appreciate the photo effect of a pinhole camera, you can use your current interchangeable lens reflex (SLR) camera. It can be made by drilling a hole of about 4 to 6mm using the body cap of the camera. As a material to make the pinhole, aluminum foil and copper foil, which are easily available, are used. Cut several pieces of copper foil into 15-20mm squares, and then drill a 0.2-0.5mm hole with a needle for sewing. Of course, processing precision (精密度) should be checked with a magnifying glass to see if it is true circle (眞圓), and even after processing, attention should be paid to copper foil wrinkling or attaching to the inside of the body cap. You can make the simplest but easiest pinhole camera by simply inserting it into the camera body when you're done. A tripod is essential when shooting, and you may need a cable release and a stopwatch. At first, you will have no choice but to ignore the exposure and shoot manually. In the case of an automatic camera, you can leave it to automatic exposure on a trial basis. However, even with an auto-exposure camera, the correct exposure may not be accurate. With bracketing, you can record the data by taking multiple shots, and then print it out to find the right exposure. You can capture your own data during this number of trial and error, and later you will remember the data just by looking at the light conditions. Depending on the light, it may take 15 to 30 seconds or more because the hole is small. Depending on the light conditions, you need the same exposure time as when shooting at night with a tripod supported. When making a pinhole camera with a hand-made product, it is made in a structure that can use Polaroid film that can be seen immediately.

The portable safety management device 100 includes a photovoltaic panel on one side, and converts light energy received through the photovoltaic panel into electric energy to charge the battery. If the amount of light is large, the amount of electrical energy can be increased. It may include an optical sensor such as an illuminance sensor to drive the solar panel. That is, when the portable safety management device 100 is installed outside, the amount of sunlight is measured to operate the solar panel unit. In addition, the portable safety management device 100 may charge a battery using electricity, and may use a general battery sold in the market. As described above, the portable safety management device 100 includes various types of battery units, and may be used as internal power by selecting an appropriate battery unit according to surrounding conditions. The portable safety management device 100 measures the total amount of power and, when power consumption is exhausted, allows nearby workers or supervisors to replace the battery through a sound output unit such as a speaker, or via the communication network 110 at the construction site. It may notify the control device 120 . The state of the amount of electricity is periodically transmitted to the construction site control device 120 so that control is performed. Thereafter, according to the control of the construction site control device 120, it may be possible to notify the outside through a speaker or the like. In the watt-hour measurement, various factors such as measuring the amount of electric charge flowing through the sensor, that is, the current, or measuring the electric power (P) by multiplying it with a voltage may be used for the watt-hour measurement. Since this can be made in various ways depending on how the designer of the portable safety management device 100 designs, the embodiment of the present invention will not be particularly limited to any one form.

Above all, the portable safety management device 100 may store the photographed image taken at the construction site therein, and transmit it to the construction site control device 120 via the communication network 110 in real time. For example, after temporarily storing a photographed image in an internal memory, etc., it is transmitted to the construction site control device 120 via the communication network 110, and when there is a response that the reception is complete, the stored data within a certain period of time may be deleted. Accordingly, the captured images may be systematically classified and stored in the DB 120a of FIG. 1 . Of course, the portable safety management device 100 may operate in various forms, such as by internally storing data and then deleting the data when construction is completed. However, when it is determined that the captured image will occupy all the storage space of the internal memory due to the occurrence of many events, or when there is a concern about data loss due to the failure of the communication network 110, the adjacent portable safety management device 100 and You can request to store the image data of the captured image by performing communication. Of course, it is possible to select and store a specific portable safety management device 100 in the vicinity of one portable safety management device 100 based on the information on the storage space of the memory by communication. Alternatively, when the portable safety management device 100 is installed at a construction site, a specific portable safety management device 100 may be designated in the vicinity or a group may be set to perform a storage operation of image data within the group. Furthermore, when there is room for storage space or when the communication network 110 is normalized again, the image data of the requested captured image is also related to how data related to the captured image of the stored adjacent portable safety management device 100 is processed. Whether to be provided again and transmitted to the construction site control device 120 or to be transmitted instead, can vary according to the intention of the system designer, so it will not be specifically limited to any one form.

In addition, the portable safety management device 100 according to an embodiment of the present invention performs beacon communication or Bluetooth communication with a working hat worn by nearby workers, a wearable device (eg, Galaxy * Gear, etc. of domestic S company), a smart phone, etc. The worker is identified, for example, the status of the worker is determined based on the worker list stored therein, or worker information is transmitted to the construction site control device 120, for example, when it is determined that the worker is in another work space. It may be possible to transmit an announcement in response to the notification.

In addition, since the portable safety management device 100 includes a GPS module, when it is first installed at a construction site, its location information can be transmitted to the construction site control device 120 through GPS or transmitted through the communication network 110 . have. Since the portable safety management device 100 has device identification information, it can be quickly identified where the specific portable safety management device 100 is installed and moved by utilizing the installed location information. For example, after the portable safety management device 100 is installed at the beginning of construction, the identification information of the device is provided as location information, and based on this, the construction site control device 120 determines where the device is installed. It can be easy. By matching the device identification information, for example, it is possible to store the location information of the portable safety management device 100 obtained through triangulation.

The communication network 110 includes both wired and wireless communication networks. Here, the wired network includes a public network or 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), and Wibro. Meaning including networks, etc. Of course, the communication network 110 according to the embodiment of the present invention is not limited thereto, and may be used as an access network of a next-generation mobile communication system to be implemented in the future, for example, a cloud computing network, a 5G network, etc. under a cloud computing environment. For example, when the communication network 110 is a wired communication network, the AP in the communication network 110 can connect to a switching center of a telephone company, etc., but in the case of a wireless communication network, it accesses the SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company to process data Alternatively, data may be processed by accessing various repeaters such as BTS (Base Station Transmission), NodeB, and e-NodeB.

The communication network 110 may include an AP. The AP includes a small base station, such as a femto or pico base station, which is often installed in a building. Here, the femto or pico base station is classified according to the maximum number of portable safety management devices 100 that can be connected to the small base station. Of course, the AP includes a portable safety management device 100 and a short-range communication module for performing short-distance communication such as zig-bee and Wi-Fi. The AP may use TCP/IP or RTSP for wireless communication. Here, the short-distance communication includes various standards such as Bluetooth, Zigbee, infrared, UHF, and VHF, such as RF and ultra-wideband communication (UWB), in addition to Wi-Fi. Accordingly, the AP may extract the location of the data packet, designate the best communication path for the extracted location, and deliver the data packet to the next device, for example, the construction site control device 120 along the designated communication path. The AP can share several lines in a general network environment, and includes a router, a repeater, and a repeater.

The construction site control device 120 monitors the construction site through the portable safety management device 100 installed at the construction site. For example, the construction site control device 120 manages the site through a photographed image provided by the portable safety management device 100 , but can selectively monitor only when an event occurs. Of course, when motion is detected by the infrared sensor, a small camera in a specified direction is operated to transmit the captured image and to be monitored through it. However, in the case of using a harmful gas sensor, for example, when harmful gas is detected, the camera can be operated, and when such various situations are detected, the camera is selectively operated to monitor it, thereby maintaining the power saving of the portable safety management device 100 provided at the construction site and at the same time controlling due to selective control. It will reduce the fatigue of the agent.

The construction site control device 120 receives a beacon signal or a Bluetooth signal through the wearable device of the worker in addition to the captured image to understand the worker situation in the work space, and monitors a specific work space when there is a work conflict between the workers. A notification may be transmitted by notifying the portable safety management device 100 .

In addition, when the battery of the portable safety management device 100 is discharged, the construction site control device 120 checks the place where the portable safety management device 100 is installed through the GPS module, more precisely, the GPS, and the battery is charged. Maintenance can also be performed easily by replacing it with an old device. More precisely, the construction site control device 120 is at the initial stage of construction, that is, at the initial stage when the portable safety management device 100 is installed, through GPS communication, or through the communication network 110, etc. of the portable safety management device 100. After the location information is identified, matched with the device identification information, and stored in the DB 120a, management can be performed. Where GPS communication is possible, accurate location measurement may be performed through triangulation using a plurality of GPS, and if GPS communication is not possible, location measurement may be performed through the communication network 110 . For example, by using a base station or access point of a general telecommunication company, it may be possible to measure the distance through signal strength or to determine the location by performing triangulation.

Since the portable safety management device 100 is miniaturized for portability, and as a result, it can be freely moved and installed at the construction site, the construction site control device 120 periodically updates the location information to provide accurate information on the construction site. A control operation may be possible. Of course, after the initial portable safety management device 100 is installed, movement of the portable safety management device 100 may occur depending on the progress of the work. Since the operation method of the small camera needs to be reset, the determination of position movement can be considered important. For example, if there is a location movement, it may mean that the work space has been changed, so the construction site control device 120 may check the work contents of the moved work space and give an appropriate notification.

When the construction site control device 120 includes a kind of server or control monitor, the manager terminal device 130 includes various devices such as a computer or a smart phone of a control agent for performing monitoring by accessing the server. can do. Through the manager terminal device 130, a supervisor or control personnel of a construction site may perform necessary setting operations or instructions, and may receive appropriate event information. For example, if there is an event notification from the portable safety management device 100 at a construction site, it will be possible to quickly respond to an incident or accident after monitoring the captured image provided by the device.

FIG. 2 is a view showing an external structure of the portable safety management device of FIG. 1 .

As shown in FIG. 2 , the portable safety management device 100 of FIG. 1 according to an embodiment of the present invention includes a solar panel part 200 , a first body part 210 , and a second body part 220 . And it may include a part or all of the control device (or driving unit) (not marked).

Here, "including some or all" means that some components such as the solar panel 200 are omitted, or the first body 210 and the second body 220 are integrated and integrated. As meant to be configured, etc., it will be described as including all in order to help a sufficient understanding of the invention.

The solar panel unit 200 includes a module for receiving sunlight. A solar module corresponds to a device that converts sunlight into electrical energy. Including a solar cell, solar energy is incident through it to generate an electric current. The direct current (DC) power generated by the module is collected and delivered to the inverter, and the inverter can convert the direct current electricity generated by the solar cell into alternating current electricity. Such AC power may be provided as a rechargeable battery. A solar cell is a photovoltaic cell manufactured for the purpose of converting solar energy into electrical energy. When light is irradiated on the contact surface of a metal and a semiconductor or a pn junction of a semiconductor, photovoltaic power is generated by the photoelectric effect. There are selenium photovoltaic cells and copper sulfite photovoltaic cells using , and silicon photovoltaic cells used as solar cells by using semiconductor pn junctions. Here, the photovoltaic power refers to the voltage generated when light is applied to the semiconductor.

The solar panel unit 200 is provided on one side of the first body unit 210 . Since the first body part 210 can be called a second body part when the second body part 220 is called a first body part, in the embodiment of the present invention, a special meaning is given to the first and second parts. I won't. For convenience of description, the first body unit 210 includes a plurality of sensors 212, a plurality of (ultra) miniature cameras 213, and an antenna unit on a frame (or first frame) 211 forming an outer edge. 214 , the sound output unit 215 , and a part or all of the connection member 216 , where “including part or all” is not significantly different from the previous meaning.

The plurality of sensors 212 may be various sensors capable of detecting a surrounding situation, such as an infrared sensor, a harmful gas sensor, and an impact sensor, in an embodiment of the present invention. For example, it is assumed that the portable safety management device 100 is installed in a hazardous area. In this case, it is possible to determine whether there is an approach of a person or the like through the infrared sensor to notify the danger, and to operate the camera 213 so that the control personnel can control the camera so that the photographing can be performed. Of course, it is preferable to turn-on only the small camera 213 for monitoring the corresponding area among the plurality of small cameras 213 . If the movement is not detected again for a specified time, the small camera 213 may enter a turn-off operation again.

The plurality of sensors 212 may be configured to follow the outer periphery of the frame 211, more precisely, four or so to be monitored in four directions of east, west, north, and south. The infrared sensor operates when a change in light received by the sensor is sensed. When an object moves, a change in light occurs, and thus the device operates.

For example, a control device including a main board (or a main board, a PCB board) provided in the first body part 210 detects the sensing signals provided from the plurality of sensors 212, and a small camera ( 213) is turned on to allow shooting. For example, when an impact sensor is provided in a corresponding direction, the small camera 213 may be operated when an event such as an impact occurs. Of course, since the small camera 213 can be operated even when the operator's beacon signal is detected in the corresponding direction, the embodiment of the present invention will not be particularly limited to any one form.

However, in the embodiment of the present invention, the portable safety management device 100 is provided with a plurality of sensors 212 to detect a movement in a specified direction, and a small camera ( 213) is selectively operated. Through this, it will be possible to save power and at the same time make efficient control of the construction site.

The antenna unit 214 is a communication unit, and includes various communication modules, such as a GPS module and a short-range communication module, to which an antenna may be connected. In the case of the antenna, it may be possible to use an antenna in the form of a pattern formed through a process such as deposition and etching of copper or tungsten in a production line.

In addition, the sound output unit 215 may include a speaker, and may output announcements or various notifications through the speaker. For example, when it is determined that the detected worker is in an inappropriate work space by detecting the worker by beacon communication, the control device receives information about this from the construction site control device 120 of FIG. 1 and transmits the pre-stored voice to the speaker. can be sent Of course, since such a control operation is possible internally without the control of the construction site control device 120, the embodiment of the present invention will not be particularly limited to any one form. In other words, when the portable safety management device 100 is initially installed at a construction site, a list of workers may be provided from the construction site control device 120 and stored therein. Based on this, it will be possible to determine the operator detected by the beacon communication and output a notification based on the voice information stored therein. Since device identification information of a user device worn by an operator is received by beacon communication, it can be used.

The second body part 220 includes a battery part 221 for accommodating the battery inside the housing, that is, the second frame, and a coupling member for fastening with the connection member 216 formed on one side of the first body part 210 . 222, a (through) hole 223 through which an electric wire for storing power or voltage provided by the solar panel unit 200 is transmitted in a battery, and a fixing unit 224 for easy installation at the construction site ) in part or in whole.

Due to the nature of the construction site, since a lot of dust may be generated, the electric wire may be connected to the solar panel unit 200 by penetrating the inside of the first body unit 210 through the hole 223 without being exposed to the outside. The connecting member 216 and the coupling member 222 may be fastened in the form of bolts and nuts, but the fastening form may be variously configured.

A plurality of rechargeable batteries may be stacked inside the battery unit 221 .

In addition, the portable safety management device 100 of FIG. 2 according to an embodiment of the present invention may include a control device such as a main board, and may include a rechargeable battery that can be charged by electricity. The same battery may be used as the solar panel unit 200 and the rechargeable battery charged by electricity. For example, if the battery is a battery for a rated voltage of 5V, electricity may be converted into DC 5V to be charged with the battery. The control device may include a CPU, an MPU, or the like, and may be responsible for the overall control operation of the portable safety management device 100 . The driving mechanism will be continued with reference to FIG. 3 .

3 is a block diagram illustrating a driving mechanism of the portable safety management device of FIG. 1 .

When the portable safety management device 100 of FIG. 1 is viewed from a driving mechanism perspective, the portable safety management device 100 ′ of FIG. 3 includes a communication interface unit 300 , a control unit 310 , a sensing unit 320 , Some or all of the camera unit 330 and the storage unit 340 are included.

Here, “including some or all” means that some components such as the storage unit 340 are omitted, or components such as the sensing unit 320 are integrated into other components such as the camera unit 330 . It means that it can be configured as such, and it will be described as including all in order to help a sufficient understanding of the invention.

The communication interface unit 300 communicates with a beacon device, a Bluetooth device, a smart phone, etc. installed on a work hat worn by a worker at a construction site, and can communicate with the adjacent portable safety management device 100 . Beacon communication may be performed with the worker's beacon device, and Bluetooth communication capable of bidirectional communication with the adjacent portable safety management device 100 may be possible. Of course, any communication is irrelevant as long as bidirectional communication such as Zigbee or Wi-Fi is possible. The portable safety management device 100 adjacent to each other through bidirectional communication may request storage of the image data of the captured image. Of course, this case may correspond to, for example, a case in which the storage space of the internal memory is insufficient due to the occurrence of many events. Since this has been sufficiently explained above, we will replace it with those contents.

The control unit 310 is responsible for the overall control operation of the communication interface unit 300, the sensing unit 320, the camera unit 330, and the storage unit 340 constituting the portable safety management device 100' of FIG. can do. Representatively, when a sensing signal (or a sensing signal) is received from a plurality of sensors constituting the sensing unit 320, the control unit 310 determines through the sensing signal in which direction the sensor has sensed, and in the corresponding direction. The camera unit 330 is controlled to operate a small camera. In other words, the controller 310 selectively operates at least one of the plurality of small cameras according to which sensor among the plurality of sensors constituting the sensing unit 320 operates. Due to the characteristics of small devices, it is possible to reduce power consumption and reduce data related to captured images to ensure smooth operation at the construction site and effective control at the same time.

The sensing unit 320 includes a plurality of sensors capable of sensing motions in four directions, respectively, of east, west, south, and north. An infrared sensor is preferable as the sensor, but various sensors may be used in order to detect a situation other than movement. For example, a distance measuring sensor may be used to measure the entry distance of the operator.

The camera unit 330 includes a plurality of small cameras to be monitored in all directions of 360 degrees. A miniature camera may include a pinhole camera. Since the small camera has an angle of view, the number of installed small cameras may be determined according to a certain angle of view. For example, if it has an angle of view of 45 degrees, it can be installed in four places in the east, west, north, south, and east like the sensor. Therefore, when the sensor in the specified direction operates, the small camera in the same direction is activated to shoot, and if no motion is detected for the specified time again, or the event object or the type of event that occurred is judged to be meaningless for control At this time, the corresponding camera may be turned off again. Here, "meaningless" means that it does not match the set information stored on the basis of a rule, or that it has little relevance to an event or accident as a result of collecting big data and analyzing the data based on deep learning of artificial intelligence (AI). can mean that Of course, since various other situations are possible, it will not be specifically limited to the above.

The storage unit 340 may store various information or data processed under the control of the control unit 310 . Representatively, it is possible to store a photographed image photographed by the small camera of the camera unit 330 . The stored captured image may be deleted when there is a response after being transmitted in real time or periodically to the construction site control device 120 of FIG. 1 , or after a specified time has elapsed.

In addition, the storage unit 340, when there is a request to store the image data for the captured image from the adjacent portable safety management device 100 under the control of the control unit 310, after temporarily storing it, and then directly The data can be transmitted to the on-site control device 120 , or the corresponding data can be deleted after being transmitted to the corresponding portable safety management device 100 again.

Furthermore, the storage unit 340 may request data storage to the neighboring portable safety management device 100 in order to preserve data in the event of an event such as a fire or an accident, and thus may store data.

In addition, the portable safety management device 100 ′ of FIG. 3 can perform various operations, and since the other detailed information has been sufficiently described above, it will be replaced with the contents.

4 is a flowchart illustrating a driving process of the portable safety management device of FIG. 1 .

Referring to FIG. 4 together with FIG. 1 for convenience of explanation, the portable safety management device 100 of FIG. 1 according to an embodiment of the present invention includes a sensor unit having a plurality of sensors on a miniaturized main body, in a specified direction. It is detected whether an event has occurred (S400). In the embodiment of the present invention, the infrared sensor detects the movement of a person or an object occurring in a specified direction, but if the shock sensor is provided, various situations such as detecting an impact may be detected. Of course, in the case of a noxious gas sensor that detects noxious gas, the occurrence of noxious gas may be detected as an event.

In addition, the portable safety management device 100 performs photographing by individually operating a camera unit including a plurality of small cameras (eg, pinhole cameras) based on a detection signal detected by at least one sensor among the plurality of sensors. do (S410). For example, if the sensors are installed in each of the first to fourth directions, when a detection signal is detected in a specific direction or when an event occurs, a small camera that monitors the direction turns on to perform a shooting operation. can be done Of course, when an event is detected in two directions, each small camera that monitors the two directions turns on and performs a photographing operation.

As such, the portable safety management device 100 controls the camera unit to perform a photographing operation by selectively turning on a small camera in a specified direction in which an event is detected when an event is detected in a specified direction based on the detection signal ( S420).

Here, "selectively" may include the meaning of turning on the small camera in the direction in which the event is generated, and turning off again when the occurrence of the event ends or no motion is detected for a specified time.

Through this operation, it will be possible to reduce the power consumption of the portable safety management device 100 formed by being miniaturized, and at the same time increase the control efficiency in the construction site control device 120 of FIG. 1 .

In addition to the above, the portable safety management device 100 can perform various operations, and since other detailed information has been sufficiently described above, it will be replaced with the contents.

On the other hand, even though it has been described that all components constituting an embodiment of the present invention operate by being combined or combined into one, the present invention is not necessarily limited to this embodiment. That is, within the scope of the object of the present invention, all the components may operate by selectively combining one or more. In addition, although all of the components may be implemented as one independent hardware, some or all of the components are selectively combined to perform some or all functions of the combined components in one or a plurality of hardware program modules It may be implemented as a computer program having Codes and code segments constituting the computer program can be easily deduced by those skilled in the art of the present invention. Such a computer program is stored in a computer-readable non-transitory computer readable media, read and executed by the computer, thereby implementing an embodiment of the present invention.

Here, the non-transitory readable recording medium refers to a medium that stores data semi-permanently and can be read by a device, rather than a medium that stores data for a short moment, such as a register, cache, memory, etc. . Specifically, the above-described programs may be provided by being stored in a non-transitory readable recording medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and it is common in the technical field to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Various modifications may be made by those having the knowledge of, of course, and these modifications should not be individually understood from the technical spirit or perspective of the present invention.
