Abstract

PURPOSE: A method for tracking a location and checking safety using a zigbee mobile is provided to obtain a location and configuration information of an adjacent mobile through a reference zigbee, thereby obtaining the location and configuration information inside a building. CONSTITUTION: A reference zigbee(S01~S06) measures a location of a signal of another mobile zigbee. A mobile zigbee(F107,F108,V106,P101) transmits locations of mobile zigbees within a short distance to a server(CS01). The mobile zigbee transmits a comparison location of an adjacent mobile zigbee to the reference zigbee. The location of the mobile zigbee is transmitted to a measuring server through the reference zigbee. The server receives ID and configuration information from the mobile zigbee.

Description

Using Zigbee to chech Real-Time Locating service and Safety}

The present invention relates to a method for confirming the location and site conditions of suppressors and volunteers in a wide range of sites such as forest fires and floods, and fires in buildings, through ZigBee wireless communication.

      The GPS system has a good performance in calculating and displaying a location by receiving GPS signals, and has adaptability to disasters in a wide range of areas.However, fire fighters can use this method to identify a location because they do not receive GPS signals inside a building. It requires another countermeasure to replace the GPS system.

      In addition, in the case of the prior patent (10-2005-0000881), at least one ZigBee detector must be installed inside the building to track its position, which is a problem in utilizing fire suppression of firefighters. In the case of ubiquitous computing, it is premised on the installation of a system for receiving signals in the building, and thus it cannot be used in the case of an existing building fire.

Accordingly, the present invention was devised in view of the above necessity, and combined and arranged ZigBees (comparable ZigBee nodes, then reference ZigBee) so that the position of ZigBee Mobile can be measured and compared to the main server (mobile computer). When mobile Zigbee crews move in the field (in and out of the building), the mobile ZigBee communicates with its plurality of ZigBee nodes the location and environmental information of its existence and neighboring mobile ZigBees at predetermined intervals between the mobiles and analyzes the transmitted data. Its purpose is to provide the location and environmental information of the members.

       The present invention for achieving the above object comprises the steps of: wirelessly communicating the comparison distance between its presence and the neighboring mobile ZigBee every predetermined period; Measuring relative positions (height and distance) of neighboring mobile zigbees through reference zigbees in which three zigbees are combined in three dimensions; And determining the current location of the mobile ZigBee and displaying the location on a computer screen on which a CAD drawing or a picture file is input.

       The present invention checks the location (distance, height, direction) and site environment (temperature, smoke concentration) of the crews in the event of fire in the site where no ubiquitous related system is installed in the building except where GPS is not applicable. I would like to. ZigBee wireless communication offers a low data rate of up to 250kbps and relays information over long distances. Therefore, there is no need to build a large server for processing data. In addition, when a node transmits information, the information relays the information received by the nodes between the transmitting node and the destination node to be delivered to the far-away destination node, although this information does not reach the far-field node. The information is passed up to the destination node.

As described in detail above, the present invention grasps the location and environment information of the nearby mobile ZigBee through the reference ZigBee to locate and use the ZigBee wireless communication even in a building where the GPS system is not available in the event of a disaster in a wide area outside the building. It is effective in identifying environmental information (temperature, smoke concentration) and helping decision makers.

      In addition, it is effective to provide additional services according to the user's location determination only by connecting the standard ZigBee and the main server beyond the existing system method that must be installed in the building in advance.

        When described in detail with reference to the accompanying drawings, an embodiment according to the present invention. 1 is an exemplary view of a reference ZigBee for location tracking inside a building for explaining the present invention.

       The standard ZigBee (S01 ~ S06) is a three-dimensional arrangement and combination of ZigBees to measure the position (distance, height, direction) of the signal transmitted from other mobile ZigBee, and together with the server (laptop) in the suppression vehicle It should be installed near the site command center in case of a fire or other disaster. Vehicles and crews carrying mobile Zigbees (F107, F108, V106, P101) in waterproof caps or tags form the relative distance and height of the base Zigbees to the measurement server when the mobile Zigbees move around the site. . The nearby mobile zigbee transmits its presence and the comparison position of the neighboring mobile zigbee to the reference zigbee at predetermined intervals. The location of the mobile ZigBee transmitted as described above is transmitted to the server through the standard ZigBee, and each ID location is displayed in a picture file or a CAD file. In the ZigBee wireless communication, the maximum ZigBee radio wave strength can be communicated at a distance of about 70 to 100 meters. Therefore, a spare mobile ZigBee is arranged in consideration of the communication failure of the mobile ZigBee (F107, F108, V106, P101). Each mobile ZigBee operates in an intercommunication mode. Mobile ZigBee (F107, F108, V106, P101) is provided or mounted on the riot fighters, volunteers and vehicles, and outputs the ID signal indicating its presence at maximum power at a predetermined cycle, and compares the position of nearby mobile ZigBee Send the location to the base ZigBee.

When the base ZigBee detects the ID signal of the mobile ZigBee, the reference ZigBee S01 to S06 transmits the ID information and the environment of the mobile ZigBee to the server CS01. Server (CS01) manages the information on the location of mobile Zigbee (F107, F108, V106, P101) located in various places, and ID and environment (temperature, smoke concentration) from mobile Zigbee (F107, F108, V106, P101). ) Information is received and the position is determined and displayed with reference to the position information of the reference ZigBees S01 to S06.

      FIG. 2 is an exemplary view illustrating a method for determining a location of resources for a global disaster according to an embodiment of the present invention. Referring to FIG. The distance is measured by comparing the information transmitted from the CS21 (wired or wired) with the positions of the reference ZigBees connected to the main server CS01.

FIG. 3 is a flowchart illustrating a method for recognizing a site (in-building and outside) location of a crew using Zigbee wireless communication according to an embodiment of the present invention. As shown in FIG. Wirelessly communicating a comparison distance of a; Measuring a relative position (height, distance direction) of a mobile zigbee located near the reference zigbee; Receiving an ID signal of a mobile Zigbee and calculating ID information at a server; Displaying a building drawing according to a CAD drawing or a picture file on a computer screen; specifying a location of the reference zigbee, a distance between the reference zigbee and the displayed building, and a building area; The display is made in comparison with the area.
