Real time safety management system based worker information of physical status and position}

The present invention relates to a safety management system based on real-time worker location and physical condition tracking, and more particularly, the location of the worker is displayed on the building layout diagram through a mobile terminal, a wearable device, and a facility detection device carried by the worker. The present invention relates to a safety management system that provides physical status information of the worker, facility information and video information at the location, and performs a risk alarm and work instruction to a worker through voice and video calls.

The safety management control system is generally a system using a mobile terminal that generates a danger signal. Such a safety management control system generates a danger signal when a user presses a specific button of the portable terminal when a dangerous situation occurs, or automatically generates a dangerous signal when an impact occurs or the portable terminal is separated from the user. This will inform the rescue organization of the danger signal that has been generated so that they can be dispatched. In addition, such a safety management control system transmits continuous location information so that the movement route can be identified at the time of dispatch, and a danger signal can be generated even when the trained route is departed so that the vehicle can be automatically dispatched in an emergency situation. In addition, after reporting the dangerous situation to the rescue organization, the user can be notified that the user is dispatched, thereby calmly dealing with the dangerous situation.

For example, Korean Patent Publication No. 10-2009-0016922 (published on Feb. 18, 2009) sets a limit on the movement of a user's mobile terminal to check for deviation and warns of the occurrence of the risk in the risk management system.

Referring to Figure 1, the safety management system of the present invention, the exhibition information providing system is a user terminal 100, wearable device 20, detection device 30, beacon 40, management server 50 and monitoring unit ( 60).

The present invention calculates the indoor location value of the user terminal using a Bluetooth beacon. The Bluetooth beacon can receive signal information even when the distance from the user terminal in the building is in the range of several tens of centimeters to tens of meters. In contrast, NFC and RFID are generally known to be available only within a few tens of centimeters. In addition, the Bluetooth method has the advantage that there is no need to tag near the reader like NFC or RFID.

The beacon 40 refers to a device that periodically transmits a beacon signal for a normal beacon service. In this case, the beacon signal may include beacon identification information, such as an identification number or location information assigned to the beacon 40, the beacon identification information is a reference that the user terminal 10 is provided with a beacon service. For example, referring to FIG. 2, six beacons are installed inside a two-story building A, and each beacon has a unique identification number and location information.

That is, when the user terminal 10 receives the beacon signal and confirms that the beacon identification number corresponds to the beacons 1 to 6 in the received information, the user terminal through the location information of the beacons 1 to 6 (Building A 2F). It can be seen that the location of the second floor of building A.

In addition, when the user terminal 10 receives the beacon signal and confirms that the beacon identification number corresponds to the beacons 7 to 14 in the received information, the user terminal through the location information (B B 3rd floor) of the beacons 7 to 14. We can see that location of Building B is the third floor.

The user terminal 10 of the present invention refers to a user device capable of transmitting and receiving various data via a communication network according to a user's operation.

It can be provided. In addition, the user terminal 100 includes a communication module 11, an input module 14, an output module 15, and a position measurement module 16.

The user terminal 10 may download a safety management application provided by the management server. The identification number or location information assigned to the beacon 40 may be stored in the memory 13 of the user terminal through the application.

The communication module 11 receives a beacon signal periodically transmitted from a plurality of beacons attached to the building.

The processor 12 calculates a location value including coordinates in a building, a floor of a building, and a floor in which the user terminal is located from the plurality of beacon signals using the location measurement module 15 at predetermined time intervals. The positioning module is a positioning program processed in the process 12.

As mentioned above, the processor may check the identification number or location information assigned to the beacon 40 to provide the building and the floor in the building of the user terminal receiving the beacon signal.

In addition, the processor 12 may calculate the position (x, y) of the worker (ie, the user terminal) at each floor using a known triangulation method.

First, the processor 12 reads the beacon signal strength received by the communication module 11 at predetermined time intervals, and calculates distances to three beacons having the largest signal strength.

More specifically, the processor 12 may calculate the distance between each beacon and the user terminal by using recived signal strength indication (RSSI). Friis' formula can be used as in Equation 1.

In Equation 1, L is a measurement distance between a user terminal and a beacon, λ is a wavelength of radio waves, and d is a distance between two points.

As shown in FIG. 2, the processor 12 obtains distances d1, d2, and d3 from the three beacons having the highest signal strengths, respectively, and is given beacons 2 (0, 10), beacons 3 (0, 20), and beacons 4. The coordinates (x, y) of worker A can be calculated using the (10, 20) coordinate values and the triangulation method.

The processor 12 may calculate the position values of workers in all buildings in the same manner.

The processor 12 may calculate the position value of the worker periodically (for example, every minute).

The processor 12 may remove the corresponding position value when the error range between the measured values before and after the periodically calculated position of the worker is greater than or equal to the reference value.

The input module 14 may include at least one of a keypad and a touch pad generating an input signal according to a user's touch or manipulation. In this case, the input module 14 may be configured in the form of a single touch panel (or touch screen) together with the output module 15 to simultaneously perform input and display functions.

The wearable device 20 is equipment worn by an operator, and may check and transmit the physical state of the operator to the user terminal. In addition, the wearable device 20 may transmit body state information to the management server 50.

The wearable device 20 may include a watch or band-shaped body part, a heart rate to pulsation sensor, a gyro sensor, a transmitter / receiver, a controller, and a display.

For example, the heart rate sensor may be formed at a portion of the body portion corresponding to the radial artery of the user to check the heart rate of the user.

Also. The wearable device 20 may detect a sudden change in position (fall, fall, etc.) of the user by using the gyro sensor.

The wearable device 20 may check the physical state of the worker more reliably by considering the pattern of the value measured by the heart rate sensor and the variation of the xylo sensor pattern simultaneously.

The transceiver is attached to the body to perform wireless communication with the smart terminal 10 or the management server 50.

The control unit is attached to the body portion, and processes the body state information of the worker measured by the sensor unit to provide to the user terminal through the transceiver.

For example, a unique identification number (for example, a MAC address) of one wearable device is stored in the memory 13 of each of the user terminals 10, and the processor 12 of the user terminal has a unique identification number. The body state information may be set to be received only from the stored wearable device.

The processor 12 of the user terminal may provide the management server with information about a unique identification number (identification ID), a user location value, physical condition information, and time designated to the user terminal.

Meanwhile, the management server may unify and store unique identification numbers of one specific user terminal and one specific wearable device. Alternatively, the management server may unify the major identification numbers of the lower stages while maintaining the hardware unique identification numbers of the user terminal and the wearable device. When the management server receives time and body state information from the wearable device, the management server may store the body state information in a lower category of the storage unit of the user terminal having the same identification number as the wearable device.

For example, the detection device may include a sensor capable of measuring carbon monoxide, carbon dioxide, oxygen, hydrogen, flammable gas, and the like.

The storage unit may store the measured facility information.

The communication unit performs wireless communication with the management server 50.

The controller determines whether the measured facility information falls within a reference range, and transmits the facility information, the measurement time, and the identification ID of the detection device to the management server through a communication unit at a predetermined time period.

The management server may store the unique identification number of one specific user terminal and one specific detection unit unified. Alternatively, the management server may unify the major identification numbers of the lower stages while maintaining the hardware unique identification numbers of the user terminal and the detection apparatus. When the management server receives the measurement time and facility information from the detection device, the management server may store the facility information at the bottom of the index of the user terminal having the same identification number as the detection device.

As described above, in the system of the present invention, the same identification number is assigned to the user terminal, the wearable device, and the detection device and stored in the management server, so that the position value can be specified even in the case of the wearable device and the detection device that do not have the location measurement module. . That is, in the present invention, the management server assigns the identification number A common to the first user terminal, the first wearable device, and the first detection device, the identification number B common to the second user terminal, the second wearable device, and the second detection device. By assigning the location value, facility information, and physical condition information can be sent to the storage under each identification number.

FIG. 5 shows a plant 3D image of a 00 power plant, a registered worker list, worker information (such as a phone number), a heart rate, a gas concentration, and a plant overall plan view. Figure 6 shows a 3D image of the HRSG building of the entire PLANT, a list of workers located in the HRSG building, worker information (phone number, etc.), heart rate, gas concentration, a plan view of the HRSG building.

The control unit 52 uses the position display module 54 to mark the position value of each worker on the building layout drawing. The position display module 54 is a position display program processed by the controller 52.

For example, the location display module may be called (identification number, time, location value) from the storage unit, the step of retrieving the information of the registered worker through the identification number, building (for example, HRSG) through the location value The method may include checking a building floor and bringing up a floor plan of the floor and marking a point matching a location value (X, Y coordinate value) on the floor plan.

If the building is clicked and there is an operator in the building, the controller can retrieve the operator's information (phone number, etc.), heart rate, and gas concentration measured by the operator from the storage unit 53 and display it in the monitoring unit. have.

On the other hand, the controller 52 may provide a change in the body state information and the gas concentration value over time.
