BACKGROUND OF THE INVENTION

1. Field of the Invention


The present invention relates to an incandescent socket connector having a beacon module for indoor positioning, and an indoor positioning system using the same. More particularly, the present invention relates to a technology capable of simply building an indoor positioning system at a low cost, by installing a beacon module for indoor positioning in an incandescent socket connector coupled to an incandescent light to make accurate indoor positioning possible.


2. Description of the Related Art


In recent years, an initial Global Positioning System (GPS) technology developed for military use is being widely used for civilian purposes of navigation, measurement, cartography and the like. Also, even a Location Based Service (LBS) using a GPS receiver as a positioning sensor has been commercialized.


But, it frequently occurs that the GPS receiver cannot receive a GPS satellite signal within doors, a metropolitan area of many high-rise buildings, an underground parking lot, a subway, a tunnel and the like. For this reason, there is a problem that the GPS receiver cannot provide consecutive user location information to a user indoors.


To fix this problem, many researches have been made on an indoor positioning technology of installing an Access Point (AP) within a building and enabling the AP to locate a target within doors using a Radio Frequency (RF) signal, and a service based on this. Active researches have been made on wireless indoor positioning technologies using infrared rays, ultrasonic waves and the like in addition to the RF signal.


The RF signal based indoor positioning technology is a technology of locating a target through a relative Received Signal Strength Indication (RSSI) received from a previously installed access point. The infrared ray based indoor positioning technology is a technology in which infrared sensors installed throughout the indoor recognize an infrared device having a unique IDentifier (ID) code and locate the infrared device. The ultrasonic wave based indoor positioning technology is a technology of locating a target using a transfer rate difference between a fast RF signal and a relative slow ultrasonic wave.


However, the aforementioned indoor positioning technologies excepting the ultrasonic wave based indoor positioning technology have a disadvantage of generally not only causing a large measurement error but also requiring very many access points, infrared sensors or the like. Also, because even an error of positioning information measurement is great more than a few meters, many inconveniences of use are caused.


Owing to the characteristic in which an RF signal is difficult to permeate walls, in many cases, the RF signal based indoor positioning technology is difficult to detect an accurate current location of a user within doors and is also difficult to detect an accurate location of the user between floors. Further, owing to a limitation on a basic reception distance of infrared rays, the infrared ray based indoor positioning technology has a problem that service is restrictive, and the cost of system installation and maintenance is very high. Further, the ultrasonic wave based indoor positioning technology enables accurate measurement, but has a problem that the cost of system installation is very high.


That is, the conventional indoor positioning technologies have a problem of having to bear the investment cost for expensive system building, because they cannot implement indoor positioning if an expensive indoor positioning system is not equipped.

The base socket part 100a is formed at an outer and lower part of a housing of the incandescent socket connector 100 and is coupled to a spiral electrode part (E1) of an incandescent lamp (L1). The socket connection part 100b is protruded and formed at an outer and upper part of the housing of the incandescent socket connector 100 such that the socket connection part 100b is coupled to a main socket (S1) fixed to a wall of a building and receives applying of a power source from the main socket (S1).


It is desirable that the base socket part 100a is constructed in a form of a female screw that is screw coupled to the spiral electrode part (E1) of the incandescent lamp (L1), and it is desirable that the socket connection part 100b is constructed in a form of a male screw that is screw coupled to the main socket (S1).


Accordingly, if the spiral electrode part (E1) of the incandescent lamp (L1) is coupled to the base socket part 100a of the incandescent socket connector 100, and the socket connection part 100b of the incandescent socket connector 100 is connected to the main socket (S1), a power source supplied from the main socket (S1) is applied to the spiral electrode part (E1) of the incandescent lamp (L1) through the incandescent socket connector 100 of the present invention and lights up the incandescent lamp (L1).


Operations of the respective constituent elements are described below in detail.
