There is a built-in controller 101 for controlling them integrally.

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.

The communication unit 110 communicates with a remote device such as a manager device 200 or another worker's worker device by short-range communication such as Bluetooth, Zigbee, or IoT communication.

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 device 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 device 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 device 200 at the 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 it to the controller 101, and the input signal does not occur for a predetermined time (for example, 30 seconds to 1 minute) from the EMG sensor 102. Or a position change value larger than the value between the settings from the gyro sensor 103 is input, an alarm signal along with the unique ID of the worker stored in the ID storage unit 106 via the communication unit 110 of the remote manager device 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 device 200, the manager device 200 is authorized through the communication unit 220 of the local area communication or IoT communication network to receive 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 device 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 immediately after the alarm signal is received.

On the other hand, if the worker is in a dangerous situation, for example, when the worker is inadvertently under work or in a collapsing area where there is a risk of falling, the manager visually witnesses this and sends it to the manager device 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.

In addition, when the operator contacts or locates the worker device 100 attached to the RFID tag 310 attached to the tool 300 to be used by the worker, the RFID reader 108 reads the RFID information of the 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 transmitting the mismatch information to the manager device 200 through the communication unit 110, the manager device 200 stores and manages it in the database 420.

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 device 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.
