For example, the control server 400 transmits a position analysis command signal for analyzing the identification information of the personal dose terminal 100 and the position of the personal dose terminal 100 associated with the alarm terminal 500, (300).

Upon receiving the position analysis command signal from the control server 400, the wireless base station 300 identifies the structure-destined personal dose terminal 100 through Received Signal Strength Indication (RSSI Based triangulation method can be used to analyze the position data of the personalized dose terminal 100 to be structured.

The Received Signal Strength Indication (RSSI) is a measure of how much the input strength of a signal is received at the receiver, and the RSSI value is based on the receiver side setting and the signal level measured on the channel.

Generally, the intensity of the RF signal is weaker as the distance increases. Therefore, the distance can be measured using this characteristic. However, due to the characteristics of the RF signal such as the interference phenomenon and the multi-path phenomenon occurring in the process of receiving the RF signal, many errors are included in converting the RSSI to the distance.

Based on the RSSI, the triangulation method can be concurrently performed to calculate accurate position data.

As shown in FIG. 4, when it is assumed that the nodes, that is, the plurality of radio base stations 300-1, 300-2, and 300-3, and the personalized dose terminal 100 to be structured exist on a two-dimensional plane, (X1, y1), (x2, y2), and (x3, y3) of the three wireless base stations 300-1, 300-2, When the distances between the target individual dose terminals 100 are d1, d2, and d3, position data according to the x, y coordinates of the target individual dose terminal 100 can be calculated.

In order to utilize this triangulation method, it is natural that each of the radio base stations 300-1, 300-2, and 300-3 should be installed at a designated location and include a unique location value.

The positional data of the personalized dose terminal 100 analyzed and calculated may be transmitted to the alarm terminal 500 of the adjacent worker along with the structure request message. For example, an alarm message as shown in FIG. 5B may be displayed have.

2, the control server 400 is connected to the control server 400 and requests information stored in the control server 400 or data processed by the control server 400 And an administrator terminal 600 for receiving response information provided from the control server 400 and monitoring the response information.

As described above, the safety management system of the present invention collects and analyzes the real-time exposure dose value to the supervisory worker performing the work in the radioactive environment, judges the risk level of the supervisory worker according to the analysis result, .

Therefore, the worker who is supervised can recognize the radiation exposure exceeding or exceeding the reference radiation dose value, so as to induce the work stoppage and evacuation, thereby preventing the radiation radiation exposure. In particular, And the rescue request is transmitted to the nearby worker by means of the urgent emergency worker, and as a result, the safety of the supervisory worker can be strengthened and secured.
