The present invention provides a method of monitoring the biological activity of a rescue member in a rescue operation and determining whether or not the rescue member is in a dangerous situation and tracking the position of the rescue personnel in a dangerous situation.

FIG. 1 is a configuration diagram of an apparatus for locating and monitoring a rescue member according to the present invention, FIG. 2 is a diagram illustrating a configuration of a search terminal of FIG. 1, FIG. 2 is a block diagram of the relative coordinate origin setting and rescue member detection according to the present invention. FIG.

Referring to FIGS. 1 to 4, an apparatus for locating and monitoring rescue personnel at risk in an indoor disaster environment using wireless communication includes a monitoring terminal 100, a server 120, and a search terminal 130 do.

The monitoring terminal 100 is a wireless communication terminal carried by each rescue party.

The monitoring terminal 100 includes a bio-activity monitoring unit 101 and an acceleration sensor 113 for collecting bio-activity through a Bluetooth low energy (BLE) communication between the temperature sensor 111 and the heartbeat sensor 112 An indoor environment location tracking unit 102 for tracking a location in an indoor environment, and a remote server communication unit 103 for communicating with a remote server 120 through wireless communication such as NB-IoT, WiFi, and Zigbee .

At this time, the data collected from the monitoring terminal 100 is transmitted to the server 120 through the remote server communication unit 103.

The server 120 includes a bio-activity monitoring unit 121 for collecting and storing bio-activities, monitoring and monitoring a dangerous state, and an indoor location tracking unit 122 for storing location tracking data.

The search terminal 130 includes a member detection unit 131 for detecting whether there is a rescue member nearby or not, a terminal for searching for a rescue member, a location for tracking the location of the current search terminal, A tracking unit 132, and a direction indicator 133 for indicating a direction for searching for a rescue party at risk.

The monitoring terminal 100 is a wearable terminal carried by all the rescuers, and is manufactured as a terminal made of a heat resistant material so that it can be used in an emergency scene. This production is not covered by the present invention.

The monitoring terminal 100 receives the bio-activity data from the temperature sensor 111 and the heartbeat sensor 112 and transmits the bio-activity data to the server 120 through the remote server communication unit 103. Further, relative coordinates can be obtained as a vector moved from a specific position through the acceleration sensor 113 until now. And transmits the position vector moved in the room to the server 120 using the acceleration sensor 113. [

In this manner, the position in the room can be tracked by using the acceleration sensor 113 to track the position in the room with the amount of change in acceleration due to the movement. That is, the acceleration sensor 113 can calculate the movement from a specific point, transmit the calculated coordinates to the server, and track the position of the rescue person based on the coordinates transmitted to the server.

The server 120 collects the bio-activity information and the location tracking data of each rescue member delivered in real time, stores it in the database, and stores it. When the bio-activity monitoring 121 information is determined to be abnormal information, To send an alarm.

Another rescue agent recognizing the alarm moves to the rescue site using the search terminal 130 to search for a rescue party at risk, and a rescue crew member Position.

At this time, in order to track the position in the indoor environment 102, it is possible to know how much the acceleration sensor 113 has moved from the reference point to the direction according to the acceleration value that is changed when the acceleration sensor 113 is moved.

However, in this measurement method, the position data to be measured becomes a relative vector value from a specific reference point (moving direction and moving distance). In order to search the rescue team using this, the reference point of the monitoring terminal 100 and the reference point of the search terminal 130 should coincide with each other. In order to accomplish this, the reference position setting terminal 400 of FIG. 4 is used in the present invention.

The reference location setting terminal 400 is a terminal for setting the same reference points of the monitoring terminal 100 used by each rescue team and the search terminal 130 for searching for a rescue party at risk.

The reference location setting terminal 400 broadcasts a beacon indicating that the reference location is located at a short time using the BLE and the monitoring terminal 100 and the search terminal 130 receive the beacon Set the point to the reference position.

As an example, suppose that a disaster scene 300 is assumed as shown in FIG. 3, and a reference location terminal 400 is located at an entrance 302 of the disaster scene.

The rescue crew must pass through the entrance 302 of the disaster site to be placed at the disaster site and receive the beacon transmitted by the reference positioning terminal 400 at this time.

If the beacon signal weakens as the rescue crew enters the building 301 (301) and the beacon signal can not be received, the position is set as the zero point which is the reference point of the coordinates. At this time, if the beacon intensity is too high and the transmission radius is large, the error to set the zero point becomes large, so that the beacon intensity should not exceed 3 meters. The server 120 transmits the distance and direction from the set zero point to the server 120 in real time, and the server monitors the bio-activity data 121 and the location tracking data 122 of the rescuers.

If the server 120 detects an abnormal symptom of the biological activity data 121 of a specific rescue member, the surveillance team immediately alerts the situation room and the command team monitoring the server, (130) and is put into the structure site.

The search terminal 130 is configured to indicate directions 201, 204, 202, 203, 205, 206 from the current page as shown in FIG. 2 Direction indicators.

The search terminal 130 receives the position data of the rescue party indicated by the server 120 and indicates the direction in which the direction from the zero point is deviated.

The lights 201, 202, 203, 204, 205, and 206 use brightness of 50 lumens or more on the characteristics of a disaster scene. At this time, the location tracking algorithm compares the location tracking value 132 of the current search terminal 130 with the location value received from the server 120 using the same algorithm as the indoor environment location tracking unit 102 of the monitoring terminal 100 And informs the position through the turn signal lamp 133.

The search terminal 130 is set by setting the location of the rescue personnel in danger at the time of site input and the BLE address of the temperature and heartbeat sensors 111 and 112 used by the rescue crew. If the body temperature and the heartbeat are detected by the temperature sensor 111 and the heartbeat sensor 112 which are worn by the rescuers who are in danger when reaching the destination, it means that there is a rescue member in the vicinity thereof, (133) to detect the crew (131) and notify that it is in the vicinity.

The present invention can rescue rescue personnel by monitoring rescue personnel to locate and track rescue personnel in order to prevent accidents and deaths during rescue operations.
