  • This application claims the benefit of Korean Patent Application No. 10-2012-0146087, filed 14 Dec. 2012, which is hereby incorporated by reference in its entirety into this application.
  • BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a fire detector 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 a fire detector 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.

  • Referring to FIGS. 1 and 2, the fire detector 100 according to an exemplary embodiment of the present invention includes a base 100 a, a cover 100 b, and a support 100 c. A power supply unit 110, an Alternating Current/Direct Current (AC/DC) converter 120, an indoor positioning beacon module 130, and a fire detection unit 140 are provided in predetermined positions of the base 100 a.
  • The base 100 a is coupled with a cover 100 b to form a smoke detection room and concurrently form a dark room within the inside. That is, the base 100 a can allow smoke to be introduced into the smoke detection room from the outside and concurrently, prevent light from being introduced into the smoke detection room from the outside.
  • Here, as illustrated in FIG. 3, the base 100 a may have a plurality of grooves (W1 to W4) for installing the power supply unit 110, the AC/DC converter 120, the indoor positioning beacon module 130, and the fire detection unit 140.
  • The cover 100 b is formed to cover a bottom surface of the base 100 a. The cover 100 b has a mesh formed in an outer wall of the cover 100 b and preventing small insects from being introduced into the smoke detection room.
  • The support 100 c is installed at the top (i.e., ceiling) within doors and supports the fire detector 100. The support 100 c has a slot (G) and, through the slot (G), the base 100 a is coupled to the support 100 c.
  • Meantime, the power supply unit 110 receives an input of a power source from the external and supplies the power source to the AC/DC converter 120. The AC/DC converter 120 converts a power source supplied from the power supply unit 110 and supplies a driving power source (for example, a voltage of 5 Volts (V)) to the indoor positioning beacon module 130 and the fire detection unit 140.
  • The indoor positioning beacon module 130 periodically wireless transmits a beacon signal including a beacon IDentifier (ID) to the external through a built-in antenna 131 (referring to FIG. 3).
  • Also, when the fire detection unit 140 detects fire occurrence, the indoor positioning beacon module 130 wireless transmits a beacon signal including a beacon ID to the external through the built-in antenna 131.

  • In this exemplary embodiment, a description has been made in which the indoor positioning beacon module 130 is provided in a predetermined position of the base 100 a but, as illustrated in FIG. 4, the indoor positioning beacon module 130 may be provided in a Printed Circuit Board (PCB) between the support 100 c and the base 100 a.
  • FIG. 5 is a diagram illustrating an indoor positioning system according to an exemplary embodiment of the present invention.
  • Referring to FIG. 5, if a fire detector 100 of the present invention wireless transmits a beacon signal including a beacon ID to a portable terminal 500, the portable terminal 500 carried by a user who is within doors receives the beacon signal from the fire detector 100, which is located around the portable terminal 500, through wireless communication.
  • Here, the portable terminal 500 refers to a terminal capable of, in a state where an indoor positioning application is executed, transmitting/receiving various data with the fire detector 100 and an indoor positioning server 900 through the wireless communication. The portable terminal 500 can be any one of a tablet Personal Computer (PC) in which wireless communication is possible and application installation is possible, a smart phone, a Personal Digital Assistant (PDA), and a mobile communication terminal. And, the portable terminal 500 can receive beacon signals from one or more fire detectors 100, respectively, because one or more fire detectors 100 can be located around the portable terminal 500.
  • After receiving the beacon signal, the portable terminal 500 extracts the beacon ID from the received beacon signal, detects a strength of the beacon signal, and stores the extracted beacon ID and the detected signal strength in a memory (not shown). The portable terminal 500 periodically includes the beacon ID and signal strength stored in the memory in a location estimation message and wireless transmits the location estimation message to the external positioning server 900.
  • In an exemplary embodiment, a header of the location estimation message includes identification information (i.e., a Manufacturer's IDentification number (MID)) of the portable terminal 500, and a body of the location estimation message includes beacon IDs (ID1, ID2, ID3, . . . ) acquired from respective beacon signals and strengths (SI1, SI2, SI3, . . . ) of the beacon signals.
  • If the portable terminal 500 wireless transmits a location estimation message to the external positioning server 900, the external positioning server 900 receives the location estimation message from the portable terminal 500, determines a location of a user who carries the portable terminal 500 on the basis of information included in the location estimation message, maps the determined location of the user on a map, and transmits the mapped location of the user to the portable terminal 500.
  • In an exemplary embodiment, the positioning server 900 may transmit the location of the user to external systems (e.g., building management systems, fire rescue systems, public institutions, information provision systems and the like).
  • That is, the present invention can detect an accurate current location of a user who carries a portable terminal using the fire detector 100 equipped with the indoor positioning beacon module 130 and accordingly, can simply build an indoor positioning system at a low cost compared to the related art.
  • Further, the present invention can detect an accurate current location of a user who carries a portable terminal on the basis of strengths of beacon signals received from fire detectors 100. Therefore, when a fire or an emergency occurs within a building, the present invention can rapidly detect location information of users and evacuate the users even without going to check if there are persons within doors one by one, making possible rapid lifesaving and initial response against the fire or emergency.
  • As described above, exemplary embodiments of the present invention have an effect of being capable of simply building an indoor positioning system at a low cost compared to the related art, by installing a beacon module for indoor positioning in a fire detector to detect an accurate current location of a user who carries a portable terminal.
