Description

System and method for providing movable GPS (Global Positioning System) signal in hospital}

The present invention relates to a system and method for providing mobile GPS (Global Positioning System) signals within a hospital. More specifically, the present invention relates to a GPS using a GNSS (Global Navigation Satellite System) to a device (terminal) of a patient or guardian moving indoors in a hospital. It relates to a mobile GPS signal provision system and method within a hospital that allows patients or guardians to easily navigate to a destination within the hospital or accurately determine their current location by providing a signal.

Satellite navigation systems, including Global Positioning System (GPS) technology, are the basis for various location-based services (LBS), including navigation. However, since the satellite signal must be received by the terminal's antenna, reception is not possible indoors in buildings, underground spaces, or tunnels, and in dense urban environments, errors in position measurement are severe due to the multi-path problem. Therefore, in order to respond to this problem, GG (GNSS Generating) technology, which simulates GPS signals and provides them, has been introduced, and inertial navigation-based DR (Dead Reckoning) has also been used.

Meanwhile, Korean Patent Publication No. 10-1597437 (Patent Document 1) discloses an “indoor positioning system and method using relative reception intensity ratio information of wireless signals,” and the relative reception intensity ratio information of wireless signals accordingly is disclosed. An indoor positioning system using at least two reference nodes installed indoors and each transmitting a wireless signal; a mobile node that measures the received signal strength indicator (Received Signal Strength Indicator) of wireless signals received from each of the reference nodes; And an indoor positioning server that measures the location of the mobile node using at least one relative reception strength ratio information of the wireless signal between the reference nodes and the reception strength of the wireless signal of each of the reference nodes measured at the mobile node. However, the wireless signal relative reception strength ratio information has a relative relationship between the reception strengths of wireless signals transmitted from two reference nodes arranged in a straight line in a 1:1 ratio among the reference nodes, depending on the position on the straight line. It is characterized by an attenuation rate.

In the case of Patent Document 1 as described above, the advantage of being able to simply measure the position of a mobile node moving indoors is by using the relative reception strength ratio information of wireless signals that change depending on the position on a straight line between reference nodes installed indoors. However, this is a technology for guardians or related persons to measure the location of mobile nodes moving indoors (e.g., lost children, elderly people with dementia, etc.), and provides a location signal directly to patients or their guardians moving within the hospital. However, there is a problem that makes it difficult to apply.
