Description

Smart safety management system for construction sites with generality and scalability

The present invention provides a general-purpose communication environment so that monitoring data transmitted from heterogeneous safety monitoring devices having different communication standards for each construction site can be efficiently collected. It relates to a smart safety management system that enables more efficient control activities and improves usability as a customized monitoring UI (user interface) is applied and expanded in conjunction with a monitoring device.

The construction industry is a labor-intensive industry in which a large number of workers are input and multiple tasks are performed simultaneously.

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

Numerically, while the number of industrial accidents decreases every year, the number of construction accidents increases every year, increasing the ratio of construction accidents to total accidents, which accounts for about 28% of all industrial accidents.

In particular, at the construction site, field workers in various fields are deployed across multiple tools to perform their own work, and managers for management and supervision of field workers perform control and management.

However, managers are placed in a significantly smaller number than field workers, which creates an area where the control and management of managers is limited. There is a problem in that safety accidents such as falling, overturning and falling occur because the manager's control and management cannot be performed.

In addition, to prevent safety accidents, most construction sites and industrial sites provide safety management education for site managers and field workers, but there is a problem with low effectiveness as it is only a formal procedure.

In other words, safety accidents that occur at construction sites or industrial sites endanger the lives of field workers, as well as cause problems such as increase in construction cost, decrease in productivity, and extension of construction period. Accordingly, there is an urgent need to introduce a systematic and efficient safety management system that can ensure the safety of field workers at construction sites and industrial sites.

It can be delivered to the mobile terminal (3) of the worker put in.

In addition, the guide message may be a notification/notice for an individual construction site or a call by a manager.

Meanwhile, according to an embodiment of the present invention, as shown in FIG. 7 , the safety monitoring device 2 is a basic line 21 in which a plurality of first beacon modules 100 are installed to be spaced apart along the boundary line of each construction site. and an incoming line 22 connecting the starting point of the communication area of the first beacon module 100 to the inside of the basic line 21 , and the first beacon module 100 to the outside of the basic line 21 . ) to include a geo-fence consisting of an outline 23 connecting the departure points of the communication area and a site area 24 in which the second beacon module 101 is installed for each of a plurality of unit areas within the construction site. can

In addition, the mobile terminal 3 outputs and transmits a request signal for recognizing the location information every preset time, and the location returned as response information from the adjacent first beacon module 100 and the second beacon module 101 Based on the information, it is possible to analyze and display the position and movement line of the operator within the geofence.

The geo-fence sets a virtual area at each construction site.

That is, the operation inside the virtual area by the geo-fence corresponds to a location where safety is ensured, and the operation outside the virtual area corresponds to a location where safety is not guaranteed.

In this embodiment, it is directly monitored through the mobile terminal 3 so that the movement of the operator is identified in the inner area of the geo-fence where safety is ensured, and, conversely, the worker moves to a location where stability is not guaranteed, that is, to a dangerous area outside the geo-fence. is to output a warning signal through the mobile terminal (3) when moving, so that the operator can recognize his/her departure information by himself/herself.

First, the geo-fence includes a basic line 21 including a plurality of first beacon modules 100 as a boundary of a specific area in an individual construction site.

At this time, the boundary of the specific area means the boundary line of the individual construction site, and a plurality of first beacon modules 100 are installed along the boundary line of the individual construction site and are basic through mutual communication connection with the mobile terminal 3 It is possible to check whether the line 21 is adjacent.

The inlet line 22 corresponds to a line connecting the starting point of the communication area of the first beacon module 100 to the inside (safe area direction) of the basic line 21 .

Whether or not the operator enters the inlet line 22 can be confirmed through the strength and direction of communication with the adjacent first beacon module 100 configured in the basic line 21 .

As shown in FIG. 8 , the lead-in line 22 corresponds to a line connecting the radius R of one side of the communication area of the first beacon modules 100 of the basic line 21 , and the lead-in line 22 From the time of passing, communication for generating the operator's location is made between the worker's mobile terminal 3 and the second beacon module 101 of the adjacent field area 24.

The outline 23 corresponds to a line connecting the departure point of the communication area of the first beacon module 100 to the outside (dangerous area direction) of the basic line 21 .

Whether or not the operator departs from the outline 23 can be confirmed through the strength and direction of communication with the adjacent first beacon module 100 configured in the basic line 21 .

As shown in FIG. 8 , the outline 23 corresponds to a line connecting the radius R of the other side of the communication area of the first beacon modules 100 of the basic line 21 . From the time of departure, the communication for generating the position of the worker between the mobile terminal 3 of the worker and the first beacon module 100 adjacent to the worker becomes inactive.

That is, in the field area 24, communication for generating the position of the worker is made between the mobile terminal 3 of the worker and the adjacent second beacon module 101, so that the movement line in the field can be grasped, and the worker can use the basic line 21 ), when the communication connection with the second beacon module 101 as well as the first beacon module 100 is weakened and the communication connection is deactivated, the worker's movement line departs in the outward direction (dangerous area direction) of the outline 23 As described below, a warning signal is generated in the mobile terminal 3 so that the operator detects it.

A plurality of second beacon modules 101 are installed in the field area 24 so that the mobile terminal 3 interacts with the adjacent second beacon module 101 from the time the operator enters the inlet line 22 . It is possible to acquire location information through communication, and by analyzing it, it is possible to grasp the location and movement line within the geo-fence (2).

The first beacon module 100 and the second beacon module 101 generate location information of the mobile terminal 3 that has transmitted the request signal in response to the request signal transmitted from the mobile terminal 3, and The location information is returned to the mobile terminal (3).

A beacon referred to in the present invention is a short-range wireless communication device based on Bluetooth low energy (BLE) technology, which can operate with a small amount of packet transmission, and is typically paired ( Pairing) is unnecessary, and since it communicates with low power, the location can be recognized at a lower cost compared to other short-distance wireless communication technologies.

Each of the first beacon module 100 and the second beacon module 101 is given area information for identifying a unit area in advance, and location information returned from the first beacon module 100 and the second beacon module 101 includes area information for identifying a unit area in which the first beacon module 100 or the second beacon module 101 is installed, so that the location of the worker can be determined through the location information transmitted from the mobile terminal 3 be able to

Meanwhile, the first beacon module 100 and the second beacon module 101 include a base 130 made of a thermally conductive material as shown in FIG. 10 ; an illumination chamber 140 in which an illumination sensor 141 and an illumination lamp 142 interlocking with the illumination sensor 141 are configured on an upper portion of the base 130; It is characterized in that it includes a PCB substrate 151 on which the beacon chip 152 is mounted, and a beacon chamber 150 in which the battery 153 is configured. In addition, the base 130 of the beacon chamber 150 is configured with a reflective plate 154.

The PCB board 151 has a beacon chip 152 mounted thereon so as to output a beacon signal and is disposed inside the beacon chamber 150 , and the battery 153 is also disposed inside the beacon chamber 150 to output a beacon signal to the PCB board 151 . ) is electrically connected to the PCB board 151 to supply power.

As shown in the drawing, the PCB substrate 151 and the battery 153 are independently disposed without overlapping areas of the areas projected inside the beacon chamber 150 . In this case, a separate contact terminal (not shown) is formed on the PCB board 151 to be electrically connected to the battery 153 to extend toward the battery 153 . The contact terminal is composed of a positive contact terminal and a negative contact terminal so as to be contact-connected to the positive electrode and the negative electrode of the battery 153 , respectively.

As described above, since the PCB substrate 151 and the battery 153 are disposed on the same plane without overlapping regions, the beacon chamber 150 can be miniaturized.

The beacon signal generated from the beacon chip 151 of the PCB board 151 is transmitted from the inner space of the beacon chamber 150 to the outer space. As a result, the beacon chamber 150 is made of a synthetic resin material to allow the beacon signal to pass through the entire surface.

However, when the beacon signal is transmitted to the rear surface of the beacon chamber 150 in the direction of the structure, the concentration of the beacon signal is dispersed to the extent that the efficiency is lowered. Accordingly, the portion of the base 130 opposite to the beacon chamber 150 is configured with a metal reflector 154, so that the concentration of the beacon signal can be improved by the configuration of the reflector 154. That is, a high-strength beacon signal is transmitted.

The base 130 uses a thermally conductive material so that heat generated from the PCB substrate 151 or the like is radiated to the outside through the base 130 . Aluminum or the like may be applied as the thermally conductive material.

In the lighting chamber 140, an illumination sensor 141 and an illumination lamp 142 interlocking with the illumination sensor 141 are configured. to make the investigation happen.

The reason for this configuration is that, in particular, when the operator deviates from the outline 23, a warning signal is expressed in the mobile terminal 3 as will be described below. However, in the case of night, it is not easy to detect the direction of the geo-fence. By the light irradiated from the lighting chamber 140 configured in the first beacon module 100 and the second beacon module 101, The operator will be able to flow in a safe direction by sensing the direction of the geo-fence.

That is, when a worker deviates from the outline 23 when working around the geo-fence at night and a warning signal is generated, it flows in the direction of the beacon module 100 to be irradiated to facilitate the flow to the safe area inside the geo-fence and the geo-fence. will do

In addition, on the rear surface of the base 130, a buffer plate 120 of an elastic material and a mounting plate 110 between the buffer plate 120 and the attachment structure (C) are further configured.

In the case of vibration transmitted from the attachment structure C, the beacon signal generated from the beacon chip 151 may be distorted. In the first beacon module 100 and the second beacon module 101 of the present invention, such vibration is An example is provided in which a buffer plate 120 made of an elastic material is further configured on the rear surface of the base 130 to control the distortion of the beacon signal by buffering.

More preferably, the buffer plate 120 has a plurality of elastic blocks 121 spaced apart to form a heat dissipation path 122 therebetween, and between the elastic blocks 121 is a connecting rod 123 made of a thermally conductive material. It is characterized in that it is connected by

Vibration transmitted from the attachment structure C configured in this way is buffered by the plurality of elastic blocks 121 , and transmitted to the base 130 by the configuration of the heat dissipation path 122 between the elastic blocks 121 . The generated heat is discharged to the outside through the heat dissipation path 122 so that the buffer action and the heat dissipation action are simultaneously expressed.

In addition, the plurality of elastic blocks 121 are connected by a connecting rod 123 made of a thermally conductive material, and the connecting rod 123 is in contact with the mounting plate 110 so that the heat flowing through the heat dissipation path 122 is transferred to the outside. As it flows out, the inside is transferred to the connecting rod 123 so that heat is transferred to the elastic block 121 to control the deformation of the elastic block 121 . More preferably, the mounting plate 110 is also made of a thermally conductive material so that the heat transferred to the connecting rod 123 is transferred to the outside through the mounting plate 110 .

Meanwhile, the mobile terminal 3 may be a smart phone of a worker entering and exiting a construction site or a portable terminal provided by a management subject to the worker for the purpose of control.

The mobile terminal 3 is equipped with a communication module capable of data communication through a single communication network, and may include a display means capable of displaying information or information about an alarm.

In this case, the communication network is an IP-based communication network that provides a large-capacity data transmission/reception service and a data service without interruption through the Internet Protocol (IP), or a wired communication network, a mobile communication network (2G, 3G, 4G, LTE), Among the Wibro (Wireless Broadband) network, HSDPA (High Speed Downlink Packet Access) network, satellite communication network and Wi-Fi (Wireless Fidelity) network, one suitable for the construction situation can be selected according to the environment.

For example, the mobile terminal 3 can transmit data to the platform server 5 using a mobile communication network such as LTE or LoRa in an exposed environment at a construction site, and can transmit data to the platform server 5 by itself in an underground space cut off from the outside. It is possible to establish a WiFi network as a network to enable communication with the platform server 5, and to receive and display guide information about an emergency situation or a disaster situation from the platform server 5.

In particular, the mobile terminal 3 outputs and transmits a request signal for recognizing location information every preset time, and the location returned as response information from the adjacent first beacon module 100 and the second beacon module 101 It analyzes and displays the movement line of the worker within the geo-fence based on the information. That is, the operator can monitor his/her own movement line within the geo-fence by the mobile terminal 3 .

This can be implemented through the APP of the mobile terminal 3, the real-time location and movement line within the geo-fence by the location information returned as response information from the first beacon module 100 and the second beacon module 101 analyzed and displayed.

An example of such a moving line is shown in FIG. 9, in which the moving line a is displayed by the mobile terminal 3 in real time within the geo-fence while the worker passes through the inlet line 22, in the moving line a, the worker While flowing in the geo-fence (2), it enters the inside through the inlet line (22) and shows an example in which the copper line disappears from the inlet line (22).

According to this moving line, the operator is recognized as flowing in the geo-fence 2 and flowing into the inside of the inlet line 22, that is, into a safe area.

After that, although not shown in the drawings, the mobile terminal 3 communicates with a plurality of second beacon modules 101 installed in the field area 24 for generating location information to determine the location in the field area 24 and It analyzes and displays the movement line.

On the other hand, in the moving line b, the moving line is displayed on the mobile terminal 10 in real time within the geo-fence 2 while the worker passes the inlet line 22. In the moving line b, the worker flows in the geo-fence and then the 23) shows an example in which the copper line disappears from the outline 23 as it is separated to the outside.

According to this movement line, the worker is considered to have flowed into a dangerous area outside the outline 23 while flowing within the geo-fence. Accordingly, the mobile terminal 3 automatically generates a warning signal when this type of movement line is formed so that the operator recognizes that he or she is in a danger zone.

Here, it is natural that the warning signal may be expressed by various means such as voice or vibration.

Meanwhile, the mobile terminal 3 may generate and display a QR code as identification information unique to the worker for attendance management for the worker.

And the system 1 of the present invention may further include a QR reader terminal 4 provided at the entrance of the geo-fence to recognize the QR code displayed on the mobile terminal 3 and output and transmit the recognition information, , the platform server 5 may receive the recognition information transmitted from the QR reader terminal 4 to manage the attendance of each worker and the number of people put in each construction site.

That is, in the present invention, when the worker generates a QR code in the mobile terminal 3 and recognizes it in the QR reader terminal 4 provided at the entrance, the recognition information is transmitted to the platform server 5 and through the remote manager terminal 6 It is possible to check and manage the number of people put into individual construction sites, such as daily, weekly, monthly, etc.

And the platform server 5 is connected to the first beacon module 100 and the second beacon module 101 to receive communication connection information with the mobile terminal 3, and transmit it from the QR reader terminal 4 If the mobile terminal 4 recognized as attendance by the recognition information is not connected to the first beacon module 100 or the second beacon module 101 within the geo-fence, it can be determined as illegal attendance.

That is, the platform server 5, in addition to managing attendance at individual construction sites for workers, the mobile terminal 4 recognized as going to work through the QR reader terminal 4 is the first beacon module 100 within the geo-fence.
