Description

Construction site integrated safety management system and safety management method using the same

The present invention relates to a construction site integrated safety management system and a safety management method using the same.

At construction sites or industrial sites, the proportion of fatal accidents caused by falls while workers are working is steadily increasing. To prevent such accidents, workers are obliged to wear safety equipment.

However, in the conventional construction site, as safety accidents frequently occur due to risks due to various environments inherent in the site itself and due to the slight negligence of workers, there is a fatal problem in that valuable human resources are lost.

In particular, since various tasks are carried out simultaneously across multiple tools at the construction site, workers in various fields are placed at the same time and perform their respective tasks. Efficient and accurate management of construction manpower is not carried out in areas where the control and management of construction is restricted. Due to these problems, safety accidents or inefficient manpower management for construction site personnel cause problems such as an increase in the overall construction cost, a decrease in productivity, and an extension of the construction period.

In a general construction site, when a safety accident occurs, the location of the worker is identified using the satellite GPS location information of the terminal device possessed by the worker. However, there is a problem that network communication is not possible at the time of initial site opening, or communication cannot be utilized in most cases because communication is not available in the underground space.

As a prior art, Laid-Open Patent Publication No. 10-2017-0006095 is disclosed. The prior art uses an application that is installed and operated on a smartphone owned by each field worker to set the type of work and the location of the job, and alerts the field worker when approaching the hazardous area to prevent a safety accident. An invention preventing this from occurring is disclosed. However, the above technique still requires the voluntary action of the field worker because the field worker must input the type of job to be performed and the location of the job directly with a smartphone.

Hereinafter, after explaining the construction site integrated safety management system according to the present invention, a safety management method using the same will be described. Among terms used herein, 'notification' means a message about a specific event situation, and 'alarm' means a warning using visual or audible means to an operator or safety manager. In addition, the 'individual sensing device' refers to an Internet of Things (IoT) device that transmits an electrical signal to transmit specific data.

'Location recognition-only module' as used hereinafter refers to the aggregate of all individual modules that determine whether there is an abnormality in the field using location information obtained from a module equipped with a location recognition-only device, and is limited to the modules described in the specification. doesn't happen

In addition, in this specification, for convenience of explanation, 'worker/heavy equipment/vehicle position sensing module' and 'operator terminal' are separately described in terms of terms, but this is a functionally divided bar, 'worker/heavy equipment/ It is specified in advance that the 'vehicle position sensing module' can be implemented in a state provided in the 'operator terminal' or in an integrated state.

The 'operator/heavy equipment/vehicle position sensing module' may be configured as a separate communication means having a position recognition-only device, and may further include an auxiliary device to be described later. 'Operator terminal' refers to a device equipped with call, notification, and alarm functions.

The following location recognition dedicated module is divided into an opening status check module, a movable safety management module, a tower crane status check module and an operator/heavy equipment/vehicle location detection module based on the equipment or device to which the location recognition dedicated device is coupled. As an example, the position recognition-only device coupled with the opening cover is classified as an opening state checking module. At this time, it is specified in advance that the individual modules included in the location recognition-only module may be configured to have additional functions according to the characteristics of the combined equipment or device.

The present invention is premised on a state in which a local network network is established. In general, mobile communication through LTE is impossible or extremely limited at a construction site, and by providing a repeater 101 for communication with various sensors that are wireless devices, a local network network is constructed.

A construction site integrated safety management system according to the present invention will be described with reference to FIG. 1 . The present invention includes a fire detection module 110 , an individual detection device confirmation module 120 , a disaster image determination module 130 , and a location recognition dedicated module 150 when classified broadly. The modules 110 , 120 , 130 , and 150 are all installed for a specific purpose, and are each configured to measure different factors.

Since it is the most important thing to suppress the occurrence of fire at the construction site, when a fire is detected by the fire detection module 110, the integrated safety management status display unit 190, the operator terminal 220 and the safety manager terminal 230 immediately ) to provide a notification of the occurrence of a fire event. Of course, it may be provided with an alarm. The fire detection module 110 is configured as an intelligent imaging device to detect flames and smoke, and is configured to detect heat (or temperature).

The individual detection device identification module 120 includes a harmful gas detection device 121 , an oxygen concentration detection device 122 , a flood detection module 123 , and an environment information collection module 124 .

The individual sensing device confirmation module 120 can detect harmful gas and measure oxygen concentration as well. Noxious gas is configured to detect all of carbon monoxide, carbon dioxide, volatile gas and combustible gas. When the oxygen concentration is abnormally low in the work space, it can have a fatal effect on the operator, and the oxygen concentration is also configured to be measured. The flood detection module 123 is generally installed in the basement, but is not limited thereto, and may be installed in a flood prevention area set by a safety manager, and includes a water level sensor.

The environmental information collection module 124 is interlocked with the information of the Meteorological Administration, which is public data, and receives weather information for a broad area, and is configured to collect weather information at a specific location within the construction site through a separate measuring device. 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 individual sensing device confirmation module 120 and the environment information collection module 124 , a signal is transmitted to the integrated safety management server 180 via the repeater 101 and integrated A notification may be provided through the safety management server 180 .

The disaster image determination module 130 analyzes the image provided from the CCTV installed at a preset location within the construction site. It is configured to use the meta information of the complex CCTV image of the site, and to check, for example, whether the worker is wearing a hard hat, whether or not there is violence and dangerous behavior between the workers, facial recognition for access control, and the health status due to thermal imaging. . At this time, it is preferable that the disaster image determination module 130 is automatically determined through the image analysis method, rather than manually determined by the administrator, by being performed by the image analysis method by deep learning.

The location recognition dedicated module 150 performs a function of transmitting location information of individual modules provided in the construction site. Here, each of the individual modules includes a location recognition-only device 150a formed to be able to communicate with the repeater 101 . The location recognition-only device 150a may be a dedicated mobile app, but may be configured as a dedicated device for transmitting location information, and any device may be applicable as long as it can transmit location information.

Additionally, the location recognition-only device 150a is a concept that further includes an auxiliary device. Here, the auxiliary device may be used, for example, as a beacon. A beacon (iBeacon) is a short-range wireless communication device based on the Bluetooth 4.0 (BLE) protocol, and can communicate with wireless devices within a maximum range of 70m. In one embodiment, the auxiliary device is not capable of direct communication with the repeater 101, but may be configured to transmit a wireless signal to the location-aware-only device 150a. In this case, the location recognition-only device 150a that has received the radio signal from the auxiliary device may be configured to transmit information about the signal to the repeater 101 .

The above-described individual modules include an opening status check module 151 , a movable safety management module 152 , a tower crane status check module 153 , and a position detection module 154 of a worker/heavy equipment/vehicle. However, it is not limited to the modules listed above (151, 152, 153, 154), and if it is a module based on location information to determine the situation of the field, additional modules with specific functions are also within the scope of the present technology. indicate that it is included.

The opening state checking module 151 is for managing the opening formed in the construction process in the construction site. The opening should be kept closed for the safety of workers unless there are special circumstances. This is to prevent the operator from falling. Each of the openings is provided with an opening cover, and the opening cover is preferably fixed in a horizontal direction and a vertical direction on the opening by forming a foot toward the lower side for close fixation with the opening. The opening cover may optionally be provided with an altitude sensor, a gyro sensor, and a GPS as positioning means. The GPS has a low utility indoors, and an altitude sensor and a gyro sensor can be used, and real-time location information of the opening cover can be specified by a triangulation method using a plurality of repeaters 101 .

The tower crane status check module 153 checks the status of the tower crane in the construction site in real time, including all of the jib and hook block positions, inclination and shaking (vibration) sensors.

The operator/heavy equipment/vehicle position detection module 154 detects the positions of the operator, heavy equipment, and vehicle by using the position recognition-only device 150a formed to communicate with the repeater 101 . The main purpose is to prevent these collisions, and in the case of heavy equipment, since the position recognition device 150a is provided in a basket, an arm, etc. separately from the body, the risk of collision between workers and heavy equipment can be prevented in advance. As described above, the operator and the safety manager can use the location recognition dedicated device 150a included in the terminal each equipped, and the operator location detection module 154 using a dedicated mobile app installed in the smartphone or a separate dedicated device. ) can also be used.

An embodiment that recognizes the approach of workers, heavy equipment and vehicles will be described. For example, when the first operator (having the location recognition-only device 150a) operates heavy equipment (an auxiliary device (eg, a beacon) is attached to a specific location), the auxiliary device attached to the heavy equipment is the first A state capable of communicating with the operator's position recognition-only device 150a is maintained (meaning a state in which communication is permitted). At this time, when the second operator (having the position recognition-only device 150a) approaches the heavy equipment, the position-recognition-only device 150a of the second operator can be connected to the auxiliary device attached to the heavy equipment. Upon reaching the location, via the repeater 101, an alarm may be provided for each of the first and second operators to warn of unauthorized access by the operator. Accordingly, both the first operator and the second operator approaching the heavy equipment recognize the current situation, so that collisions and stenosis in the construction site can be prevented in advance.

The local network applied to the present invention includes a Wi-Fi network (meaning an Internet network) and a wireless device network (meaning a sensor network). For example, the Wi-Fi network may be formed with a 2.4 GHz or 5 Ghz frequency, and the wireless device network may be formed with a 900 MHz band, but is not limited thereto, and all frequencies of the 'unlicensed band' are applicable. In addition, WiFi (wireless fidelity), Bluetooth, Bluetooth low energy (BLE), Zigbee (Zigbee), NFC (near field communication), magnetic secure transmission (Magnetic Secure Transmission), radio frequency (RF), or body area network (BAN) It is specified in advance that communication is possible with any one of them.

For communication with the above-described 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 .

The integrated safety management server 180 includes a location analysis engine 181 , a fire detection and analysis unit 182 , an individual detection device analysis unit 183 , and a location recognition dedicated module status check unit 184 . The location analysis engine 181 is configured to collect location information of sensors that are the target of the location recognition dedicated module status check unit 184, and their locations are displayed in the integrated safety management status display unit 190 in a 2D or 3D method. can be displayed as In other words, the location analysis engine 181 performs a function of displaying the collected information on the integrated safety management state display unit 190 in a method desired by a user or an administrator (eg, a map method). In this process, the X-axis, Y-axis, and Z-axis coordinate information received from the location recognition-only device 150a may be utilized.

The fire detection and analysis unit 182 and the individual detection device analysis unit 183 calculate the measured values transmitted from the fire detection module 110 and the individual detection device verification module 120 in a preset manner, respectively, to reduce the risk of fire and gas leakage. It determines the risk and performs the function of providing an alarm or notification. The individual sensor analysis unit 183 also collects and processes environmental information from the environmental information collection module 124, for example, when the wind speed is 15 m/s or more, the operator terminal 220 and the safety manager terminal 230 ) to display a warning notification or provide a response scenario. In addition, when the fire detection and analysis unit 182 and the individual detection device analysis unit 183 determine whether a fire has occurred and the gas concentration (eg, oxygen) is out of a preset range, an alarm is sent to the operator terminal 220 . can be transmitted In this way, by generating an alarm in the operator terminal 220, it is possible to warn the operator and recognize whether a danger has occurred.

The position recognition dedicated module status check unit 184 will be separately described later.

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

Described in terms of work, the present invention further includes a field alarm device 210 , an operator terminal 220 , and a safety manager terminal 230 .

The on-site alarm device 210 is provided at a preset position in the construction site, and is configured to provide an alarm to the operator at the preset position using a visual or audible method. A visual method is through lighting (warning light, emergency light), and an audible method is to generate a warning sound through a speaker. Since the on-site alarm device 210 is provided with a separate emergency call device, it may be configured so that an operator can make an emergency call with another worker or a safety manager using the emergency call device in case of an emergency.

The worker terminal 220 is provided to each worker, and is a device provided with a location recognition-only device 150a and a call means. The present invention can use the Internet network by using the repeater 101, so that the use of a smart phone is possible. Since the smartphone has a built-in GPS, all functions can be used through the dedicated mobile app installed on the smartphone. In addition, the user may use a dedicated device equipped with the location recognition dedicated device 150a in addition to the smart phone, and the dedicated device may be configured to communicate wirelessly with a separate communication means and communicate through the repeater 101. .

The safety manager terminal 230 is also functionally similar to the operator terminal 220 . It is desirable to use the integrated safety control mobile app, and through this, you can check all notifications when a fire, gas leak, environmental information, and management situation occurs. By doing so, there is an advantage that a quick response is possible.

2 and 3, the application method of the opening state checking module 151 will be described.

The method includes steps S11 to S15.

In the integrated safety management server 180, through the location analysis engine 181, the location of the opening status check module 151 in the construction site is specified and displayed on the integrated safety management status display unit 190. At this time, when the safety manager or the central manager selects the location of the opening status checking module 151 on the screen, the location of the opening status checking module 151 is displayed in the center of the screen. The opening state checking module 151 receives wind direction and wind speed information through the bar, which can be moved by the wind, and the environment information collection module 124 . The integrated safety management server 180 may transmit an inspection request message (meaning 'notification') to the operator terminal 220 and the safety manager terminal 230 when a management situation occurs. At this time, the safety manager and the plurality of workers may perform a group call to handle the occurrence of a management situation.

In step S14, in order to determine the cause of the management situation, the corresponding worker information is identified through the inquiry of the work report. The safety manager or central manager can exchange opinions on the occurrence of management situations with the identified workers.

In step S15, if the cause of the occurrence of the management situation is not determined, it is necessary to return the opening state checking module 151 to its original position, so that the safety manager can use any operator (preferably, the current adjacent to the opening). You can request a status check from the worker at the location) or instruct the appropriate worker by performing a group call.

A method of applying the disaster image determination module 130 and the location detection module 154 will be described with reference to FIGS. 4 and 5 . Here, the position detection module 154 transmits the position information of the operator, heavy equipment, and construction vehicle through the repeater 101 . First, the disaster image determination module 130 performs AI image analysis by using the meta information of the complex CCTV image. As described above, it is determined whether the worker wears a hard hat and whether or not there is violence/dangerous behavior between the workers. For example, whether or not there is a violent/dangerous action between workers can be determined by overlapping images of objects. In addition, the disaster image determination module 130 receives information from the location detection module 154, and through image analysis, detects a collision between a worker, heavy equipment, and a construction vehicle. Displayed on the safety management state display unit 190, an alarm is generated in the operator terminal 220 of the worker (approaching worker).

In step S25, the safety manager or the central manager directly checks and determines the management situation image, and when it is determined as the management situation, a notification is provided to the operator terminal 220 of the worker again. At this time, the approaching heavy equipment and construction vehicle may be provided with an alarm unit, through the alarm unit, it is possible to recognize the approach of the operator to the driver of the heavy equipment and construction vehicle.

With reference to FIGS. 6 and 7 , the application method of the fire detection module 110 and the individual detection device identification module 120 will be described. The method includes steps S31 to S35. Of course, the environmental information collection module 124 can be further used, and by receiving public data provided by the Meteorological Administration, and calculating the data in a preset manner, it is possible to precisely analyze the data.

When a fire is detected by the fire detection module 110, the management situation is activated, and is immediately displayed on the integrated safety management state display unit 190, and at the same time, the operator terminal 220, the safety manager terminal 230 and the field A signal is generated in all of the alarm devices 230 . Since a fire at a construction site can greatly escalate in a short time, it is preferable to provide a notification to all worker terminals 220, rather than only providing a notification to the operator terminals 220 adjacent to the fire place.

In step S31, the individual detection device identification module 120 is always operated as a fixed device in the construction site, and when the concentration of the detected gas reaches a dangerous value, it is treated in the same way as a fire. Because of the widespread nature of the gas, it is necessary to evacuate workers as soon as possible.

In addition, in step S32 , the fire detection and analysis unit 182 and the individual detection device analysis unit 183 generate an alarm for whether a fire has occurred and the gas concentration (eg, oxygen) is out of a preset range. It can be transmitted to the operator terminal (220). In this way, by generating an alarm in the operator terminal 220, it is possible to warn the operator and recognize whether a danger has occurred.

An application method of the position sensing module 154 will be described with reference to FIGS. 8 and 9 . This method is partly different from the disaster image determination module 130 described above. The disaster image determination module 130 uses image analysis to determine the risk of collision between workers and heavy equipment, whereas this method uses a location recognition dedicated device 150a provided in each operator/heavy equipment/construction vehicle.

In step S42, the situation where the heavy equipment/construction vehicle approaches within the preset safety area based on the operator is determined as the management situation by the location recognition dedicated module status check unit 184. For the operator's recognition in step S43, an alarm is generated from the heavy equipment/construction vehicle, as well as an alarm generated from the corresponding operator terminal 220, thereby inducing a quick response of the operator. Then, in step S44, after the management status is confirmed by the safety manager, an emergency notification is provided to the operator terminal 220.

With reference to FIGS. 10 and 11 , the application method of the tower crane status check module 153 and the flood detection module 123 will be described. The method includes steps S51 to S55.

The location and status check of the tower crane in step S51 and the submersion status check of a specific location (including the basement) may be operated at all times or may be configured to be checked at a preset cycle. This may be changed according to the selection of the program designer.

In step (S52), the management status of the tower crane is the risk of collision, the risk of strong wind, the risk when out of the preset inclination range (meaning the jib of the tower crane, the tower mast, the crane runway, the inclination of the cab), It means a risk of exceeding a preset vibration value. Since the tower crane is greatly affected by the wind direction and speed, it is preferable to consider the wind direction and wind speed information provided from the environmental information collection module 124 in order to determine whether the management situation of the tower crane occurs. For example, when the wind speed is 10 to 30 m/s or more, a warning notification may be generated in both the operator terminal 220 and the safety manager terminal 230 . In step S54, after the occurrence of the management situation is confirmed again by the safety manager, it is determined.

12 is a conceptual diagram for explaining a method of performing a group call between a plurality of workers and a safety manager in the construction site integrated safety management system according to the present invention.

As described above, the present invention is based on the premise that a local network network is established in the construction site, and the individual sensing device, the on-site alarm device 210, the operator terminal 220 and the safety manager terminal 230 are all repeaters ( 101) and is configured to communicate. In FIG. 12, the analysis by the integrated safety management server 180 will be described in a state where the analysis is omitted. Here, 'abnormal detection' is a broad concept that encompasses the occurrence of a management situation. Hereinafter, the 'group call' will be described in detail.

First, when an abnormality is detected in an individual detection device, the individual detection device generates a management condition occurrence signal. The signal is transmitted to the on-site alarm device 210 through the repeater 101, and the on-site alarm device 210 recognizes the signal as an alarm generation indication signal. Accordingly, the on-site alarm device 210 that has received the signal generates an alarm. The management situation occurrence signal generated from the individual sensing device is transmitted not only to the on-site alarm device 210 , but also to the operator terminal 220 and the safety manager terminal 230 . Here, it will be described based on what is transmitted to the safety manager terminal 230 . When the safety manager terminal 230 receives the management situation occurrence signal, the safety manager may apply for a group call, and the group call request signal is transmitted to the operator terminal 220 via the repeater 101 . At this time, it may be transmitted to a plurality of operator terminals 220 , and the operator terminals 220 receiving the group call may perform a group call with the safety manager terminal 230 .

The second case is when the operator confirms an abnormality detection. When the operator confirms the detection of abnormality in the construction site, the group call can be requested while transmitting a management situation forced occurrence request signal to the safety manager terminal 230 through the operator terminal 220 . In this process, the on-site alarm device 210 may also receive the signal, and thus may generate an alarm. This is premised on the assumption that the operator does not have the authority to generate a management situation, but the safety manager. The safety manager who has received the management situation forced occurrence request signal or group call request signal can make a judgment about the occurrence of the management situation and can perform a group call. In addition, the operator may generate an emergency call to the safety manager terminal 230 .

Third, when the safety manager detects an abnormality, the management situation is forcibly generated and a group call is applied. Like the second, in this process, the on-site alarm device 210 may also receive the signal, and thus may generate an alarm. In addition, the safety manager may transmit an emergency notification to the operator terminal 220 .

In this way, when a plurality of workers perform individual tasks, group calls can be very useful for quick communication. Since the signal can be transmitted only by the repeater 101 without going through the integrated safety management server 180, it is possible to quickly respond to the occurrence of a dangerous situation in the construction site.

13 is a conceptual diagram for explaining signal verification of a repeater in the construction site integrated safety management system according to the present invention.

The conventional repeater 101 has only served to transmit the received signal to the integrated safety management server 180 as it is. By retransmitting all signals without verifying the received signals, overload of the integrated safety management server 180 is caused, and there is a problem in that the operation speed is lowered.

To solve this, the repeater 101 included in the present invention does not deliver all the received signals, but verifies the signals in terms of uniqueness and effectiveness, and filters only the signals with uniqueness and validity, so that the integrated safety management server ( 180) is a configuration that is transmitted.

Referring to FIG. 13 in detail, a plurality of location recognition-only devices may be provided in the construction site, these are the opening status checking module 151, the tower crane status checking module 153, and the location detection of workers/heavy equipment/vehicles. It may be composed of a module 154 and the like, but for convenience of description, only the location recognition-only device is shown and described. In addition, the repeater may also be configured in plurality.

As shown in FIG. 13 , the communication signals generated by the first to fourth location recognition-only devices may be received not only by the repeater 1 but also by the repeater 2 . Referring to FIG. 13 , while the signal generated by the first and second location recognition-only devices is well received in the repeater 1, the signal may not be received relatively well in the repeater 2, and even if received, the signal strength is It may be smaller than a preset size or may be cut off frequently. This is due to the distance or obstacle between the location-aware-only device and the repeater. Repeater 2 needs to filter all of these signals in order to prevent overload of the integrated safety management server 180 in advance. That is, repeater 2 considers signals having a signal strength smaller than a preset size or frequently cut off as problematic signals, and classifies them as 'invalid signals'. Signals classified as invalid signals are filtered, and are not transmitted from the repeater 2 to the integrated safety management server 180 .

As described above, by filtering the communication signal in the repeater itself, it is possible to increase the transmission efficiency and operation speed of the communication signal.

In addition, the repeater recognizes their location through communication with the location recognition dedicated device 150a included in the individual module of the location recognition dedicated module 150, and the location coordinates (X, Y, Z-axis coordinate information) can be configured to transmit.

The module selected by the user is displayed in the center of the screen. For example, all conditions within the construction site, such as equipment, workers, sensors, and openings, are mapped and displayed.

Fig. 15 shows the UI at a specific point in time of construction. The UI shown in FIG. 15 may be changed for each construction time, for example, the UI of the foundation earthwork time, the frame construction time, and the finishing work time point may be configured differently.
