The process safety management system of the present invention may further include a wearable device 20 carried by an operator.

The present invention calculates an indoor position value of a 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 within a range of several tens of meters to several tens of meters. In contrast, NFC and RFID are generally known to be available only within a few tens of centimeters. In addition, Bluetooth has the advantage that it does not have to be brought close to a reader like a NFC or RFID tag.

The beacon 40 means a device that periodically transmits a beacon signal for a normal beacon service. At this time, the beacon signal may include beacon identification information such as an identification number or position information allocated to the beacon 40, and the beacon identification information is a criterion on which the user terminal 10 is provided with the beacon service. For example, referring to FIG. 2, six beacons are installed inside a two-story building in building A, and each beacon has a unique identification number and location information.

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

The processor 12 uses the position measurement module 15 to calculate a position value including a coordinate value in a building, a building layer, and a floor where the user terminal is located from a plurality of beacon signals at predetermined time intervals. The position measurement module is a position measurement program that is processed in the process (12).

As described above, the processor can identify the identification number or location information allocated to the beacon 40, and provide the building in the building or the building in the user terminal that has received the beacon signal.

Further, the processor 12 may calculate position (x, y) of an operator (i.e., user terminal) in each layer using a known triangulation method.

First, the processor 12 reads the beacon signal intensity received at a predetermined time interval in the communication module 11, and calculates distances between the beacon signals having the largest signal intensity.

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

In Equation 1, L is the measured distance between the user terminal and the beacon,? Is the wavelength of the radio wave, and d is the distance from the two points.

2, the processor 12 obtains distances d1, d2, and d3 from the three beacons having the highest signal intensity, and obtains a given beacon 2 (0,10), beacon 3 (0,20) (X, y) of the operator A can be calculated by using the coordinates (10, 20) and the triangulation method.

Alternatively, the hardware identification number of the user terminal and the detection device may be kept unchanged, and the identification numbers of the major ends of the lower ends thereof may be unified into the management server. When the management server receives the measurement time and facility information from the detection device, the management server can store the facility information at the bottom of the index of the user terminal having the same identification number as the detection device.
