Description

Wearable apparatus for safety supervisory of construction field workers

The present invention relates to a wearable device for worker safety management at a construction site, and in particular, attached to the body of the worker in the form of a patch to monitor the movement of the worker, warning of danger zones, and whether the correct working tool is used. The present invention relates to a wearable device for worker safety management of a construction site that enables the worker to immediately check the location of the worker's investment by smoke screen when the worker is buried in the collapse of the building.

Various safety accidents that occur at the construction site are most often caused by carelessness of workers, and such carelessness may include accidents caused by falling objects and accidents caused by falling.

In order to minimize the injuries of workers due to such accidents, various safety equipments are worn. Typically, safety helmets are worn to prevent accidents caused by falling objects, and safety belts are worn to prevent falling accidents. The safety hook installed on the site will be hung on the safety rope installed to prevent the fall accident.

However, most workers do not wear a hard hat or a safety loaf ring because they are bothersome or inconvenient to work, so that the workers are constantly exposed to safety accidents.

In order to solve this problem, Korean Patent Laid-Open Publication No. 10-2012-0083946 (safety hat wearing management device of the construction site) is equipped with a sensor on the hard hat to send information on whether the worker wearing it correctly to the remote site, and alerts the worker to the alarm A structure for generating a has been proposed.

In addition, Patent No. 10-0966892 (Safety management device for construction sites using RFID) is equipped with a sensor in the safety ring to send information on whether the safety ring is correctly caught in the safety equipment for the fall prevention, and to alert the worker A structure for generating sound has been proposed.

However, these conventional technologies are not able to quickly grasp when the worker is in an accident, it is not possible to quickly grasp whether the survival also has a great difficulty in the structure.

For example, when a worker is buried in a pile of concrete during the collapse of a building under construction, the buried position cannot be quickly identified and the structure is delayed, and the delay may significantly reduce the possibility of survival.

In addition, the use of various tools, for example, electric drill, electric cutter, electric saw, electric screwdriver, electric taka, hydraulic cutter, etc., provided on site, may cause safety accidents caused by unauthorized persons, The problem of loss or theft also arises because it is not possible to grasp the correctly recovered state without being left on the next site.

The present invention is largely composed of the operator device 100, the manager terminal 200, the tool storage box 400.

As shown in FIG. 1, the worker device 100 may have a structure that may be attached to or worn on the body of an operator, or may have a structure having a band 100-2 that may be worn on a wrist in the form of a watch. Can be.

The worker device 100 is provided with a high brightness LED 105 and a worker button 109 on the upper side, and the EMG electrode 102-1 and a pair of low frequency electrodes on the upper side as shown in the side structure shown in FIG. 104-1 is provided to make contact with the operator's skin.

In addition, as shown in Figure 3, the inside of the operator device 100 is connected to the EMG electrode 102-1, the EMG sensor 102 for detecting the movement of the user, the gyro sensor for detecting the fall of the operator ( 103, a low frequency generator 104 for generating a low frequency to the low frequency electrode (104-1), and an RFDI reader 108 is built in, the unique ID of the worker and the ID of another worker, that is, the same space or the same as the worker ID storage unit 106 stores IDs of workers working in a building, tool ID storage unit 107 stores IDs of tools approved for use by workers, and communication unit 110 for short-range or IoT communication. A smoke container 111 filled with a smoke material having a color, and a controller 101 for controlling them integrally are incorporated.

The EMG sensor 102 senses the state of muscle movement of the worker, and detects whether or not an accident occurs due to the worker.

The gyro sensor 103 may detect a sudden change in the position of the worker, that is, a fall, and the like, and detect the change of the position when the fall occurs in the building.

The low frequency generating unit 104 can not warn workers of danger in the construction site with high noise, so that the alarm can be recognized through low frequency stimulation. Supply to the worker through the electrode (104-1).

The high-brightness LED 105 allows the rescuers to quickly check the location of the worker in the field in a state where the worker cannot move due to fainting, falling, etc., and is also a means for checking the location of the worker during night work.

The ID storage unit 106 stores and stores a unique ID of a worker who works on the worker device 100 and an ID of a fellow worker, that is, IDs of workers who work in the same space or building.

The tool ID storage unit 107 stores the ID of a tool approved by the operator. For example, if only the operator is authorized to use a special tool that cannot be used by another operator, the ID of the tool is stored. .

The RFID reader 108 reads RFID information from the RFID tag 310 attached to the tool 300 as shown in FIG.

When the worker button 109 is pressed in an emergency, the worker button 109 generates an alarm signal to other workers working around, i.e., other workers stored in the ID storage unit 160. In addition, the low-frequency stimulus enables the user to quickly recognize the alarm condition so that they can quickly evacuate or respond.

In addition, the operator button 109 is provided with smoke screen ejection button.

The communication unit 110 communicates with a remote administrator terminal 200 or worker devices of other workers by short-range communication such as Bluetooth, Zigbee, or IoT communication.

The smoke container 111 is filled with the smoke material having a color and ejects the smoke material filled therein when the valve 111-1 is opened. The smoke material is harmless to the human body and is easily visible, such as orange, yellow, and red. It has a color.

The controller 101 integrates and controls each of the circuit blocks, and a rechargeable battery is built in the worker device 100 to supply power.

The manager terminal 200 may be in the form of a tablet computer or a smartphone, or may be worn by a manager in a wearable form. The manager terminal 200 may include a display unit 230, an alarm unit 240 for notifying an acoustic alarm, a manager button 250, The communication unit 220, and the MPU 210 to control them integrally.

Tool storage box 400 is to receive and store the tool 300 to which the RFID tag 310 is attached, and to check whether the tool used in the field is correctly recovered, and to store each of the tools 300. Has a storage space 410, and each storage space 410 is provided with an RFID reader 430.

In addition, the tool storage box 400 is provided with a database 420 stored by matching the unique ID information of each RFID reader 430 installed in each storage space 410 and the RFID information of the tool 300, respectively, The processor 440 is configured to transmit a match to the manager terminal 200 at a remote location through the communication unit 460.

The operation of the present invention having such a configuration will be described.

First, when an operator attaches the operator device 100 to the skin or wears it on the wrist, the EMG electrode 102-1 and the low frequency electrode 104-1 are worn to contact the skin. Provides the sensing information for the muscle exercise state to the controller (101).

In addition, the gyro sensor 103 also detects a sudden change of position information of the worker and provides the same to the controller 101, and the input signal is not generated from the EMG sensor 102 for a predetermined time (for example, 30 seconds to 1 minute). Or when the position change value larger than the setting value is input from the gyro sensor 103, the alarm terminal together with the unique ID of the worker stored in the ID storage unit 106 via the communication unit 110 of the remote manager terminal 200 Will be sent to.

That is, when no input is generated from the EMG sensor 102, it is a state in which the worker is not moving, and it can be determined that the unconsciousness or death is caused by various accidents, and the input from the gyro sensor 103 is If it occurs, it can be determined to be caused by a fall or a shock, which can be an emergency situation.

At the same time, the controller 101 lights up the high-brightness LED 105 to visually inform the location of the worker who caused the accident so that rescuers can quickly know the location of the worker who has the accident.

Of course, when working at night or in a dark place, the high-brightness LED 105 is turned on so that the worker's working position can be easily checked.

To this end, the operator device 100 may further include an illuminance sensor, so that the controller 101 may properly light the high-brightness LED 105 by the light quantity measurement value of the illuminance sensor.

Therefore, when the worker device 100 transmits the worker ID and the alarm signal accordingly to the manager terminal 200, the manager terminal 200 is authorized through the communication unit 220 which is a local area communication or IoT communication network and receives the MPU ( 210, the MPU 210 visually notifies the emergency situation of the worker through the display unit 230, and at the same time, the alarm unit 240 visually notifies the emergency situation.

Therefore, the manager can judge the situation immediately by such an alarm signal and respond to the accident.

In addition, the manager terminal 200 is stored in the contact information of the police station or fire station, and will be able to automatically make a rescue request through the communication unit 220 as soon as the alarm signal is received.

On the other hand, if the worker is placed in a dangerous situation, for example, when the worker is working in a collapsed area under the falling object or the danger of falling due to the carelessness of the worker, the manager visually witnesses this and the manager terminal 200. When the provided manager button 250 is input, the MPU 210 transmits an alarm signal to the worker device 100 designated by the manager through the communication unit 220.

That is, when the manager inputs a worker's name or ID through the display unit 230, the MPU 210, in which the worker's information is stored in advance, transmits the worker's ID information, that is, an alarm signal through the communication unit 220. Then, the worker device 100 receives the ID information through the communication unit 110 to provide to the controller 101.

Accordingly, when the controller 101 matches the ID of the worker stored in the ID storage unit 106, the controller 101 quickly and accurately recognizes that the worker is exposed to a dangerous situation by supplying the low frequency stimulus to the worker through the low frequency generator 104. Make it possible to evacuate or respond.

Then, when the worker presses the worker button 109 of the worker device 100 when he or she is in a dangerous situation or other workers around the dangerous situation, the controller 101 stores the ID storage unit 106. Read the ID of the other workers stored in the alarm unit through the communication unit 110 is generated.

The alarm signal may be an alarm signal including IDs or IDs of other workers.

Therefore, the worker device worn by another worker can respond quickly by supplying the low frequency stimulus to the worker by such an alarm signal.

Of course, even when a work button is input from another worker terminal, the worker device 100 receives the same through the communication unit 110, and the controller 101 provides the low frequency stimulus to the worker through the low frequency generator 104. To quickly recognize the risk situation.

On the other hand, when the building under construction collapses and the worker is buried in a pile of concrete, the buried location must be quickly identified and rescued. Will be lowered.

Therefore, in order to quickly grasp the position of the operator, the controller 101 opens the valve 111-1 of the smoke container 111 so that the charged smoke material is ejected to the space between the concrete piles so that the rescuer Allows the operator to quickly and easily determine the location of the investment.

For this purpose, when a collapse accident occurs, when the manager button 250 of the manager terminal 200, that is, a button for smoke emission and a name or ID of an invested worker are inputted, the information of the worker is stored in advance. The ID information and smoke emission signal of the worker is transmitted through the communication unit 220, the worker device 100 receives the ID information and smoke emission signal through the communication unit 110 to provide to the controller 101. do.

Accordingly, when the controller 101 matches the ID of the operator stored in the ID storage unit 106, the controller 101 opens the valve 111-1 of the smoke container 111 to fill the smoke material filled in the smoke container 111. By ejecting, the rescuer can accurately confirm the location of the worker's investment.

Of course, if the worker is conscious after the collapse of the building, and presses the smoke-blowing button of the worker button 109 of his worker terminal 100, the controller 101 immediately outputs a valve control signal to the valve 111-1. As a result, the valve 111-1 is opened to eject the smoke screen material filled in the smoke container 111 so that the rescuers can quickly confirm this.

Alternatively, as described above, the controller 101 receives a value input from the gyro sensor 103 or the EMG sensor 102, and the controller 101 receives the valve 111-1 by a valve control signal. By controlling the smoke screen material can be ejected from the smoke container (111).

That is, when no input signal is generated from the EMG sensor 102 for a predetermined time (for example, 30 seconds to 1 minute) or a position change value larger than the setting value is input from the gyro sensor 103, this means that an accident occurs. Therefore, the controller 101 opens the valve 111-1 by the valve control signal so that the smoke screen material is ejected from the smoke container 111, so that the structure of the worker can be quickly identified.

Therefore, because the smoke screen material lighter than air is compressed and filled in the smoke container 111 for generating the smoke screen, the smoke screen material ejected at the time of the buried accident rises through the gap of the collapsed concrete pile, and also in case of an accident to the worker. The location can be quickly identified, allowing rescuers to quickly identify it.

The smoke container 111 is integrally installed on the worker device 100, but when the volume of the smoke container 111 is large, a smoke generating unit 500 is provided separately as shown in FIG. It can be worn on work clothes.

The smoke generating unit 500 includes a communication container 510, a valve driving unit 520, and a smoke container 530 having a valve 530-1 in the form of a module, and the communication unit 510 is an operator. The device 100 is connected by wire or wirelessly.

Therefore, when the smoke emission signal is input from the manager terminal 200, the controller 101 of the operator device 100 transmits a valve control signal to the smoke generation unit 500 through the communication unit 110.

The communication unit of the smoke generating unit 500 receives the valve control signal and provides the valve driving unit 520 to the belt driving unit 520. As a result, the valve driving unit 520 opens the valve 530-1 to form an interior of the smoke container 530. It is possible to eject the smoke screen material filled in.

In addition, even when the smoke blowing button is input from the operator terminal 100 to receive the valve control signal from the worker device 100 to eject the smoke screen.

In addition, as mentioned above, even in an accident state in which there is no fall, shock, or physical activity, the valve control signal from the operator device 100 is received from the smoke generating unit 500 of the smoke container 530. It is possible to eject the smoke screen material filled inside.

On the other hand, when the operator contacts or located near the RFID tag 310 attached to the tool 300 to be used by the worker device 100, the RFID reader 108 reads the RFID information of such a tool Provided to the controller 101, the controller 101 reads the ID information stored in the tool ID storage unit 107 and checks whether they match each other to determine whether the operator uses the approved tool.

Even if the operator does not make contact with the RFID tag 310 while keeping the operator device 100 on his / her wrist, when the tool 300 is to be used, the RFID information may be automatically read at a short distance.

Therefore, if the RFID information of the tool 300 read in this way is inconsistent with the ID information stored in the tool ID storage unit 107, the controller 101 applies an low frequency stimulus through the low frequency generation unit 104 so that the tool is not applied. By generating a warning signal for use, and by transmitting the mismatch information to the manager terminal 200 through the communication unit 110, the manager terminal 200 is stored in the database 420 to manage.

The alarm signal and the warning signal through the various low frequency stimulus mentioned above allow the operator to grasp the type of signal by changing the low frequency.

On the other hand, when the operation is finished, the tool holder 400 should be checked whether the tool is correctly recovered when the tool storage box 400 is stored and stored, for this purpose each storage space 410 formed in the tool storage box 400 ), And the RFID reader 430 provided in each storage space 410 reads RFID information from the RFID tag 310 attached to the stored tool 300.

When the RFID reader 430 provides its ID information and the RFID information of the read tool 300 to the processor 440, the processor 440 may identify the ID of the RFID reader 430 previously stored in the database 420. By reading the information and the RFID information of the tool, by comparing the ID information input from the RFID reader 430 and the RFID information of the tool with each other it is confirmed whether the match.

If it does not match, the processor 440 transmits to the manager terminal 200 through the communication unit 460, so that the administrator can check the action and take action.

That is, to prevent the tool from being left in the wrong or wrong place.

In addition, the communication unit 220 of the manager terminal 200 is configured to enable not only IoT but also LTE communication, so that various kinds of information can be uploaded to a cloud server through a gateway and made into a database.

As described above in detail specific parts of the present invention, it is apparent to those skilled in the art that such specific descriptions are merely preferred embodiments, and thus the scope of the present invention is not limited thereto. something to do.
