Description

A mobile safety box for integrated safety management at construction sites}

The present invention relates to a mobile safety box that can be easily moved for safety management at a construction site.

The proportion of fatal accidents due to falls and fire accidents while workers are working at construction sites or industrial sites is steadily occurring. To prevent such accidents, workers are obliged to wear safety equipment, and a safety manager is appointed for each zone or team to check safety.

However, in a complex construction site, it is difficult to prepare for all safety accidents with only a small number of safety managers and individual safety equipment because many workers simultaneously perform various tasks in various places.

Accordingly, smarter management is sometimes achieved by providing workers with a GPS module as a necessity, or by developing and installing an app that can be used in a terminal (smartphone, etc.) possessed by the worker.

However, since the communication network is installed by the telecommunications company only after the construction is completed, in most cases, general communication cannot be performed at the construction site during construction, and the GPS module may not operate normally due to difficult satellite signal reception due to thick concrete structures. Wi-Fi network is also not provided. In this case, it is difficult to determine the location of the worker using the terminal, and it is also difficult to deliver an emergency situation using an app installed on the terminal.

The location of workers is also linked to labor planning. Whether the worker is actually working or resting in an invisible place, it is impossible for the safety manager or the integrated control room to check all of them. In fact, the current labor planning at construction sites is carried out in a very primitive way, so the accuracy is low.

If the number of important work equipment is small, it is very important to effectively establish a plan for using work equipment in order to shorten the construction period. However, in most construction sites, the planning and use of work equipment is recorded by relying on manpower. Therefore, it is uneconomical to rent a lot of work equipment unnecessarily, or the number of rental work equipment is insufficient, and the air supply may increase.

Korean Patent Registration No. 10-2086079 proposes a mobile safety management device to solve this problem. Since this device is movable in various construction sites, it has an advantage that it can be used in sites where communication facilities are not provided. In addition, since the mobile safety management device can detect the sensor attached to the worker's helmet by BLE, it is confirmed whether the worker is located nearby.

However, this prior art has a disadvantage that it is difficult to identify the location of the mobile safety management device. It is identified that the worker is located around the mobile safety management device, but it is not known where the device is located. If the mobile safety management device, which should be located in building 101 at the apartment construction site, is located in building 102, the locations of workers are all confused and cannot help being recorded or managed. Even if the GPS module is included, accuracy is low in construction sites where there are many spaces where it is difficult to receive satellite signals as described above.

In addition, although the fact that the worker is located around can be transmitted to the server, the fact is not notified to the safety manager located in the actual site. For example, there may be an urgent moment to check whether there is an accident because the location of one worker is not known. The safety manager who must check this on site is located near the mobile safety management device and does not visually observe the display unit. I don't even know if there are any. As described above, considering a construction site where general communication is difficult, communication through a terminal possessed by a safety manager is also difficult. After all, the safety manager must have a separate wireless communication device, and the integrated control room must inform the safety manager with the wireless communication device. This is not significantly different from the previous environment in which the mobile safety management device according to the present prior art is not used.

1. Construction site integrated safety management system description

For description of the movable safety box according to the present invention, first, the overall safety management system including the movable safety box will be described with reference to FIG. 1 .

The present invention is based on the assumption that a local network is established. In general, a local network is built by providing a plurality of repeaters 101 for communication with various sensors, which are wireless devices, since mobile communication through LTE is impossible or extremely limited at a construction site.

The safety management system includes a fire detection module 110, a gas detection module 120, an environmental information collection module 130, an opening status confirmation module 140, an individual detector status confirmation module 150, a disaster image analysis module 170 ).

The modules 110, 120, 130, 140, 150, and 170 are all installed for specific purposes, and are configured to measure different factors.

The individual detectors are composed of a movable safety box 151, a tower crane status check module 152, a submerged detection module 153, and a position detection module 154. The location where they are installed may be stored in advance in the integrated safety management server 180, and their locations may all be displayed on the integrated safety management state display unit 190.

Since suppressing the occurrence of fire at a construction site is one of the most important matters, when a fire is detected by the fire detection module 110, the integrated safety management status display unit 190, the worker terminal 220, and the safety manager terminal Through (230), a warning about the occurrence of a fire event is provided. The fire detection module 110 is composed of an intelligent imaging device to detect flame and smoke, and is configured to detect heat (temperature).

The gas detection module 120 is configured to detect harmful gases and also measure oxygen concentration. Harmful gases are configured to detect all of carbon monoxide, carbon dioxide, volatile gases and combustible gases. If the oxygen concentration is abnormally low in the work space, it can have a fatal effect on the worker, so the oxygen concentration is also configured to be measured together.

The environmental information collection module 130 is configured to interwork with the public data, Meteorological Agency information, receive weather information for a region in a broad sense, and collect weather information of a specific location within a construction site through separate measuring equipment. Weather information is a broad concept that includes temperature, snowfall, rainfall, wind direction, wind speed, fine dust concentration, noise information, and vibration information.

Here, when a specific factor reaches a dangerous value by the gas detection module 120 and the environmental information collection module 130, a notification may be provided through the integrated safety management server 180.

The opening status checking module 140 is for managing openings formed during the construction process in a construction site. Openings should remain closed for the safety of workers unless there are special circumstances. This is to prevent workers from falling. Each opening is provided with an opening cover, and it is preferable that the opening cover is fixed in a horizontal direction on the opening by forming a foot downward toward the opening for close fixation with the opening. The opening cover may be provided with a tracker 15 in which GPS, altitude sensor, gyro sensor, temperature sensor, and vibration/shock sensor are integrated.

Disaster image analysis module 170 analyzes the image provided from the CCTV installed at a preset location in the construction site. It is configured to use the meta information of the complex CCTV images of the site, and check, for example, whether the worker is wearing a hard hat, whether there is violence and risky behavior between workers, facial recognition for access control, and health status by thermal image. . At this time, it is preferable that the disaster image determination module 170 is automatically determined through the image analysis method, rather than manually determined by a manager, by being performed by an image analysis method based on deep learning.

The individual sensor device status confirmation module 150 checks the status of individual sensor devices provided in the construction site. Here, the individual detectors include a movable safety box 151, a tower crane status check module 152, a submerged detection module 153, and a position detection module 154. The movable safety box 151 will be separately described later.

The tower crane status checking module 152 checks the status of the tower crane in the construction site in real time, including all of the jib and hook block positions, tilt and shaking (vibration) sensors.

The flood detection module 153 is generally installed on a basement floor, but is not limited thereto, may be installed in a flood prevention area set by a safety manager, and includes a water level sensor.

The location detection module 154 uses a tracker configured to communicate with the repeater 101 and detects the locations of workers, heavy equipment, and vehicles. The main purpose is to prevent collision between them, and in the case of heavy equipment, the risk of collision between workers and heavy equipment can be prevented in advance by providing trackers on baskets and arms separately from the body. Workers and safety managers may use the location detection module 154 by using a dedicated app of their own terminal.

As described above, the present invention assumes a state in which a local network is built, and is a broad concept including both a Wi-Fi network and a Lora network. For communication with the aforementioned module, a repeater 101 is provided, and a plurality of repeaters 101 may be provided at appropriate locations to cover the entire area of the construction site. The repeater 101 serves as a gateway for communication with the integrated safety management server 180. However, when the construction site is large, it is common that the Wi-Fi network is not provided in all areas. To this end, the Wi-Fi router 1142 is provided in the mobile safety box 151. This is described later.

The integrated safety management server 180 includes a location analysis engine 181, a fire detection and analysis unit 182, a gas detection and analysis unit 183, an environment information analysis unit 184 and an individual detection device analysis unit 185. . The location analysis engine 181 is configured to collect location information of sensors that are subject to the individual sensor device analysis unit 185, and their locations are displayed in 2D or 3D on the integrated safety management state display unit 190 It can be.

The fire detection and analysis unit 182 and the gas detection and analysis unit 183 calculate the measured values transmitted from the fire detection module 110 and the gas detection module 120 in a preset manner, respectively, to determine the risk of fire and gas leakage. and to provide warnings. The environmental information analysis unit 184 collects and processes environmental information, for example, displays a warning notification to the worker terminal 220 and the safety manager terminal 230 when the wind speed is 15 m/s or more, or responds to the scenario. can provide

The integrated safety management status display unit 190 receives the calculated information from the integrated safety management server 180 and provides the information in a preset manner. It is preferable to visually express it to a safety manager or central manager, and since a search engine is provided, it is also possible to manage multiple construction sites as one integrated program.

If described from the point of view of work, the present invention further includes a field notification device 210, a worker terminal 220 and a safety manager terminal 230.

The site notification device 210 is provided at a preset location in the construction site, and is configured to provide a notification to a worker at a preset location using a visual or auditory method. A visual method is a method through lighting (warning lights, emergency lights), and an auditory method is a method of generating a warning sound through a speaker. The on-site notification device 210 may be configured so that a separate emergency call device is provided so that a worker can make an emergency call with another worker or safety manager using the emergency call device in case of an emergency.

Since the integrated control room equipped with the integrated safety management server 180 knows the location of the field notification device 210, when an emergency warning occurs in the mobile safety box 151, the nearby field notification device 210 can work together. This is described later.

The worker terminal 220 is provided to each worker and is a device equipped with a position sensor and a communication means. The present invention can use the Internet network using the repeater 101, it is possible to use a smart phone.

The safety manager terminal 230 is also similar to the worker terminal 220 in terms of functionality. It is desirable to use an integrated safety control mobile app, through which you can check all notifications in case of fire, gas leak, environmental information, and management situations, and if necessary, group calls with multiple workers By doing this, there is an advantage that quick response is possible.

2. Description of the movable safety box

Referring to FIGS. 2 and 3A to 3C , the movable safety box 151 according to the present invention will be described in detail.

The mobile safety box 151 according to the present invention includes a power communication module 1100, a system module 1200 and other additional devices.

The power communication module 1100 supplies power to the mobile safety box 151 and performs a function of communicating with the main servers through the repeater 101 .

The repeater 101 is based on a Wi-Fi communication method, and simultaneously transmits and receives while serving one or more communication methods such as 1Ghz (900Mhz band), LoRa, or BLE.

The power communication module 1100 includes a constant power connection line 1110 capable of supplying power at the site where the power source is installed, a switch 1120 for turning on/off the device, and a power source capable of charging power. It includes a battery 1130 that supplies power to the device in an undisclosed field.

In addition, the router 1150 receives information from the system module 1200 and delivers it to the main servers through the repeater 101, and the wireless signal received through the repeater 101 is amplified to form a Wi-Fi zone in the vicinity. A Wi-Fi router 1140 and a GPS are provided so that the location of the mobile safety box 151 can be checked, and signals transmitted by nearby beacons 10 can be identified to identify which beacons 10 are nearby tracker 1160. After confirming the information, the tracker 1160 transmits and receives the relay 101, but may communicate directly, communicate through the router 1150, or communicate in various other ways. In the present invention, communication occurs through the router 1150. defines it as a concept that includes all of them.

The Wi-Fi sharer 1140 amplifies the wireless signal received through the repeater 101 to form a Wi-Fi zone in the vicinity. As disclosed in the prior art, there are many cases where general communication networks as well as Wi-Fi do not operate at construction sites, so general workers who are not equipped with wireless communication devices or satellite communication equipment rely only on voices or warning lights to recognize emergency situations. Dangerous. However, according to the present invention, a signal is transmitted through the router 1150 in the repeater 101 connected to the local network, and a Wi-Fi zone is provided around the mobile safety box 151 by the Wi-Fi router 1140, Workers can communicate through their terminals 220 . Therefore, the worker receives a warning about an emergency situation in the form of a notification as various applications installed on the worker terminal 220 (eg, an integrated safety control mobile app provided by the construction company - see FIGS. 10 and 11, a commercially available general messenger app, etc.) Direct reception is possible, greatly increasing work stability.

The tracker 1160 enables the current location of the movable safety box 151 to be confirmed. The confirmed location is transmitted to the integrated safety management server 180.

In addition, the tracker 1160 may identify and receive a signal transmitted from the fixed beacon 10 . The fixed beacon 10 is fixedly installed in a building under construction, so even when satellite communication for GPS does not operate normally due to a thick concrete structure, etc., it is determined which signal generated by the beacon 10 is received most strongly and is currently mobile. The position of the safety box 151 can be estimated. That is, it has a great advantage that it is possible to check the location of the mobile safety box 151 even in a place where satellite communication is not good.

In addition, the tracker 1160 can identify which beacon 10 is within a predetermined distance when the beacon 10 provided by the worker or work equipment is located within a predetermined distance, through which the location of the worker and work equipment and You can check working hours. Details will be described later when the work time calculation unit 1240 is described.

The tracker 1160 is capable of communication and identification with other trackers 15 . For example, even when a tracker 15 other than the beacon 10 is provided or attached to a worker or work equipment, the tracker 15 in the movable safety box can identify it. Therefore, if any one of the beacon 10 and the tracker 15 is provided or attached to a worker or work equipment, all of them can be identified, and through this, which worker and which work equipment are around the movable safety box, how much, and how to move Jira is remotely verified.

The tracker 1160 is equipped with various sensors including GPS. By the built-in GPS, the location of the tracker 1160, that is, the mobile safety box, is confirmed in the integrated safety management server 180. In addition, since an altitude sensor, a gyro sensor, a temperature sensor, etc. are built-in, various information such as the tracker 1160, that is, what floor the movable safety box is on the site, how tilted it is installed, and how much acceleration it moves, etc. can be checked.

An antenna 1170 is provided to assist in wireless communication.

A method for confirming the location of a movable safety box using the tracker 1160 will be described. As described above, since the tracker 1160 is equipped with a GPS, when a satellite signal is strong, the location of the mobile safety box can be easily checked through the GPS. However, when GPS operation is difficult due to weak satellite signals, it may be difficult to accurately identify the location of the mobile safety box. confirmed with high accuracy.

A plurality of repeaters 101 are provided at the construction site. The location of each repeater 101 is recorded in the integrated safety management server 180.

In addition, a plurality of beacons 10 are also fixed and located. Similarly, the location of a plurality of beacons 10 is recorded in the integrated safety management server 180 .

Workers or work equipment may be equipped with a tracker (15). The tracker 15 here is different from the tracker 1160 installed in the movable safety box, and is referred to as “another tracker 15” for description. The integrated safety management server 180 is in a state of checking the real-time location of a plurality of other trackers 15 .

Two types of information are used to determine the location of the mobile safety box when the satellite signal is weak.

First, it is the location information confirmed in the signal transmitted with the beacon 10 or other trackers 15 pre-installed at the construction site. At this time, multiple signals may be received. By identifying the beacon 10 or other tracker 15 that transmitted the strongest signal, the beacon 10 or other tracker 15 closest to the mobile safety box is identified. You can check. For example, if signals of beacon A, beacon B, and tracker C are received, but the signal having the strongest intensity is a signal transmitted from beacon B, it is confirmed that the mobile safety box is close to beacon B. Since the integrated safety management server 180 knows the location of the beacon B in advance, the location of the mobile safety box is first estimated.

The second is location information confirmed by the repeater 101 communicating with the mobile safety box. It is identified which repeater 101 communicates with among a plurality of repeaters 101 installed in the field. Through this, the repeater 101 closest to the mobile safety box is identified, and the location of all repeaters 101 is integrated safety management server ( 180), the location of the movable safety box is secondarily estimated.

In this way, by using two pieces of location information, the location of the mobile safety box is confirmed with high accuracy even when the satellite signal is weak.

The system module 1200 includes a remaining amount indicator 1211 provided outside the movable safety box 151 to display the remaining battery power in conjunction with the battery 1130, and a movable safety box 151 to output various information. It includes a main display 1212 provided on the outside, a warning light 1213 capable of blinking and outputting high-intensity light, and a speaker 1214 outputting sound.

A sensor unit 1220 is further included. The sensor unit 1220 is mounted inside to be in fluid communication with the gas intake unit 1225 exposed to the outside.

The sensor unit 1220 may include a noxious gas sensor 1221 , a temperature and humidity sensor 1222 and a fire smoke sensor 1223 . There is no restriction on the type of harmful gas detected by the harmful gas sensor 1221, but in one embodiment, it is configured to detect all of carbon monoxide, carbon dioxide, volatile gas and combustible gas according to the construction site. If the oxygen concentration is abnormally low, it is configured to measure the oxygen concentration as well, since it can have a fatal effect on the operator. The fire smoke sensor 1223 may include a sensor capable of detecting a flame, so that whether or not a fire is detected can be identified by detecting smoke generated in the event of a fire or by detecting a flame.

The sensing value detected by the sensor unit 1220 may be directly output to nearby workers on the main display 1212 . Accordingly, a worker located near the movable safety box 151 can visually check whether the colorless and odorless noxious gas has a certain concentration or higher while looking at the main display 1212 . The detection value can be transmitted to the integrated safety management server 180 through the repeater 101 so that the integrated control room can monitor it. In addition, the detection value transmitted to the integrated safety management server 180 may be output from the worker terminal 220 and the safety manager terminal 230.

Intelligent CCTV (1230) is a device for taking a surrounding image. As shown in Figures 3a and 3b, the intelligent CCTV (1230) is provided on one side of the handle 1320 provided at the end of the extension portion 1330, when the mobile safety box 151 is not used, the extension The part 1330 is not extended and stored inside the movable safety box to protect the intelligent CCTV 1230 from foreign substances, and only when the movable safety box 151 is used, the movable safety box ( 151) It protrudes outward and can be used. By this method, the intelligent CCTV (1230) can take a picture of the surroundings at a relatively high position, so more information can be checked and recorded.

The video recorded by the intelligent CCTV (1230) is transferred to the integrated environmental safety server (180) and recorded. In the integrated control room, images transmitted from a plurality of movable safety boxes 151 placed in various locations in the construction site can be checked, comprehensively recorded, and managed.

In addition to the aforementioned general CCTV functions, the intelligent CCTV 1230 may perform a people count function for counting the number of workers identified on the screen, a fall detection function for detecting a worker's fall, and a fire detection function for detecting a fire. Through this, it is possible to double-check information detected by other parts. For example, as described above, the number of nearby workers is confirmed through the beacon 10 and the tracker 1160, which is double checked through the people count function of the intelligent CCTV 1230. Whether or not there is a fire is confirmed through the fire smoke sensor 1223, which is double checked through the fire detection function of the intelligent CCTV 1230.

The working time calculation unit 1240 checks communication between the beacon 10 or other trackers 15 and the tracker 1160 provided by the worker or work equipment to determine the location and working time of the worker.

A worker or work equipment is equipped with a beacon 10 or other tracker 15 when working. A worker may have the beacon 10 or another tracker 15 as a separate device itself, but may also be provided in a helmet that the worker always carries. The beacon 10 or other trackers 15 do not overlap with each other and periodically transmit distinguishable signals, and the tracker 1160 can receive and identify signals transmitted by the beacon 10 or other trackers 15 . Since the transmission distance of the signal transmitted by the beacon 10 or other tracker 15 is limited, if the tracker 1160 receives the signal transmitted by a specific beacon 10 or other tracker 15 during the correction time, this is This means that a worker equipped with the beacon 10 or other trackers 15 has been located around the movable safety box 151 for a predetermined period of time. By adjusting the receiving distance of the tracker 1160 to the work effective distance, the working time calculation unit 1240 can identify whether the worker is in a working position and how long the working time has been at the position. The location and working time of the identified worker are transmitted to the integrated safety management server 180, and may be transmitted to the worker terminal 220 and the safety manager terminal 230 in some cases.

For example, if there is a worker who needs to work on rebar for 5 hours on the 10th floor of Building 101, the mobile safety box 151 located on the 10th floor of Building 101 must receive the worker's beacon 10 signal for 5 hours. If the mobile safety box 151 does not receive the beacon 10 signal of the corresponding worker at all, it can be estimated that the corresponding worker failed to work. If the signal of the beacon 10 of the worker was received only for 2 hours, and there is no other mobile safety box 151 receiving the signal of the worker's beacon 10, the worker was negligent, or 5 It means that the plan set in time is wrong.

For another example, if the ready-mixed concrete vehicle needs to move to building 110 for work, if the mobile safety box in building 111, not building 110, confirms the transmission signal of the tracker 15 of the ready-mixed concrete vehicle approaching it, the work manager By instructing the vehicle driver to move to building 110, work time can be shortened and wrong construction can be prevented.

Therefore, by using the movable safety box 151 according to the present invention, it is also possible to check whether a worker or work equipment has sufficiently worked in an appropriate position, and through this, a labor plan can be elaborately modified. For example, it is possible to accurately check how many workers actually work for how many hours to perform the work, and in case of post-completion defects, it is possible to check which worker worked and when, making it clear who is responsible. may be In addition, safety management may be performed in advance by checking the access of heavy equipment.

The work time calculation unit 1240 has a built-in timer. When the timer start signal is applied, the time starts calculating, which is output through the main display 1212. If the environment is not good and you have to leave after working for a certain amount of time (eg, a work space where you have to leave after working for 3 hours), it is effective to use the working time calculation unit 1240 including a timer.

The emergency communication unit 1250 receives an emergency broadcast transmitted from the integrated safety management server 180 and outputs it through the speaker 1214. In the case of sending an emergency broadcast from the integrated control room, if the situation cannot be propagated to all workers only by the on-site notification device 210, the mobile safety box 151 plays a large role.

In addition, the emergency communication unit 1250 can make a call through a wireless network using the router 1150 or the tracker 1160. Since a wireless communication network is used rather than a general communication network operation, in a disaster situation where a general communication network is not available, a worker near the mobile safety box according to the present invention can use the emergency communication unit 1250 of the mobile safety box to communicate with the person in charge of the integrated control room, , through which the on-site situation can be communicated and safety instructions can be received.

It is detachable from the movable safety box and further includes a detachable tilt sensor unit 1260 attachable to work equipment. The operator can detach the detachable tilt sensor unit 1260 from the movable safety box 151 and attach it to desired work equipment. For example, it is attached to the H-beam being transported to check the inclination of the corresponding H-beam, and when the H-beam is installed, the detachable inclination sensor unit 1260 can be recovered here.

The detachable tilt sensor unit 1260 includes a tilt sensor and a communication unit. The communication unit may transmit the detected value of the tilt sensor to the integrated safety management server 180 through the power communication module 1100. In one embodiment, as the slope is output on the main display 1212, the operator may be directly notified of the value.

By the configuration of the detachable tilt sensor unit 1260 as described above, it is possible to check the tilt of any work equipment that is essential in a work site but does not have a tilt sensor.

The emergency button 1270 is provided on the outside of the movable safety box 151. If a worker nearby the mobile Anjan box 151 directly recognizes an emergency situation, he or she can press it. In this case, the warning light 1213 and the speaker 1214 operate, and the situation is transmitted to the integrated safety management server 180 . The integrated safety management server 180 can operate the on-site notification device 210 installed in the work space within a preset range based on the position of the mobile safety box where the emergency button 1270 confirmed by the tracker 1160 is pressed. there is. In addition, the location of the mobile safety box and an emergency situation may be transmitted to the worker terminal 220 and the safety manager terminal 230 . In other words, when the operator presses the emergency button 1270 of the movable safety box 151, the warning light 1213 and speaker 1214 of the movable safety box 151 operate, and at the same time, the nearby on-site notification device 210 ) is operated, and the corresponding situation is transmitted to the worker terminal 220 and the safety manager terminal 230.

Through the floodlight 1280, light for work is provided even in a dark work space where no power source is installed. As revealed in the prior art, in order to work before a power source is installed in a dark work space such as a basement, a temporary lighting device connected to the outside with a heavy and long wire had to be installed first, and separate demolition work after completing electrical or lighting work had to be removed. According to the present invention, if only the movable safety box 151 is moved, the floodlight 1280 can be operated by the battery 1130 for a certain period of time, so the installation of temporary illuminators can be omitted or minimized, thereby shortening the construction period. can try

Meanwhile, looking at another configuration of the movable safety box 151, since a pair of large wheels 1310 are provided at the rear lower end, the operator can easily move the movable safety box 151 to a desired position by tilting it.

In addition, on the upper side, an extension part 1330 capable of extending vertically is provided, and a handle 1320 is further provided at its end. Therefore, when moving the movable safety box 151, the operator can extend the extension part 1330 according to his or her height and then move it using the handle 1320. A bracket 1340 is provided on the lower side. The bracket 1340 can be connected to a support such as a tripod (see FIG. 3c ), so that the height of the movable safety box can be adjusted. It helps secure the field of view of the intelligent CCTV (1230) and accurately detects the sensor unit (1220).

The extension part 1330 also helps secure the field of view of the intelligent CCTV 1230 in addition to helping the movement. The intelligent CCTV 1230 is provided on one side of the handle 1320, so that if the extension 1330 is not extended, it is accommodated inside the box, and if the extension 1330 is extended, it is located outside the box and takes pictures with a wide angle of view.
