Definitions
- the present invention relates to a position information communication device using a mobile phone, and more particularly to a position information communication device capable of reporting the position of a mobile phone caller in an emergency.
- Mobile phones are a major element supporting Japanese industry today. In Japan, 70 million mobile phone terminals are used. Mobile phone terminals are not limited to telephone functions, but are equipped with infrared reading devices, have cameras, capture images, and in some cases also recognize images. In addition, they have come to have RF-ID tags. If you have a mobile device, you will have the function of a credit card and, in some cases, even an ID card. Mobile devices are taking over the position of PCs in the 1990s.
- GPS Global System for Mobile Communications
- a receiver is installed in a mobile phone to receive radio waves from multiple satellites and send a position to 110-119. There is a way to tell the location.
- the former is possible in a space suitable for satellite reception, and its position cannot be detected in buildings, underground shopping malls, valleys of buildings, valleys of mountainous regions, and in tunnels.
- the latter is possible within the range of the radio wave of the mobile phone, but the radio wave propagates complicatedly, so the position accuracy is not good.
- the error is usually several hundred meters, which is not enough for emergency dispatch.
- LEDs have high power efficiency, reliability and long life. Another thing that cannot be overlooked is the high-speed response of LEDs. Utilizing this good response characteristic, it can also be used for optical wireless communication.
- An object of the present invention is to accurately obtain position information of a mobile phone by using optical wireless communication using illumination light.
- the present invention provides a position data section for generating position information, a modulation section for modulating an electric signal on a power line with the position information of the position data section, A lighting unit for generating illumination light by an electric signal modulated by the information; a light receiving unit receiving the illumination light modulated by the position information; and detecting the position information from the light receiving unit.
- the mobile phone includes a position information detecting unit and a processing unit that transmits the detected position information from the transmitting / receiving unit of the mobile phone.
- the light receiving unit that receives the illumination light modulated by the position information is better to use the camera provided in the mobile phone.
- the present invention modulates the position information of a light source of a lighting device used for display, lighting, an emergency light, a guide light, and the like by a visible light receiving element installed in a mobile phone, and receives light in a very close proximity. By doing so, the location of the mobile phone can be accurately transmitted to the 110-119 It is useful information for action.
- FIG. 1 is a diagram showing a schematic configuration of an embodiment of the present invention.
- an emergency light or a guide light (illumination device) 10 that is lit for 24 hours is installed, and modulates with information on the position to generate visible light (illumination light).
- the mobile phone 20 having a visible light receiving unit for example, a camera or the like
- emergency communication for example, 110th to 119th
- voice information it is possible to automatically add location information as data communication.
- the form of location information sent to the receiving organization for mobile phone power emergency calls is, for example, "ordinary address display + detailed information (for example, location in a building)" or "latitude and longitude + detailed information”. is there.
- the house display can be represented only by alphanumeric characters, etc., if the same as the customer's bar code indicating the address used in the mail.
- the range of light is narrower than radio waves and the like, and the direction is strong immediately.
- the point force has a limit in the visible light communication range.
- the mobile phone can automatically send the information obtained from the location, including the light and light communication power, and send the information on the caller's location to the 110-119 control room. This makes it possible to send detailed location information such as the exact location, for example, the corridor near Room No. X on Building X. Emergency lights and guide lights are lit 24 hours a day, and It is easy to get location information because it is in the place where it is attached. It is obvious that position information can be transmitted from general lighting equipment.
- FIG. 2 is a diagram showing a configuration for performing communication from the mobile phone 20 to an emergency call control room (emergency call receiving organization) 60.
- the mobile phone 20 that has obtained the position information from the guide light or the like 10 is communicating with the base station 30 via the voice communication channel and the data channel.
- the emergency call receiving organization 60 receives an emergency call from the base station 30 via the mobile communication network 40 and the gate station 50.
- the location information is communicating via a data channel.
- Gate station 50 via the data 'channel Communication control is performed with respect to the positional information communicated.
- the caller who notifies the emergency information reports the emergency to the receiving organization (command room) 60 of the emergency call by voice.
- the mobile phone 20 automatically transmits the position information obtained from the guide light 10 or the like to the emergency call receiving organization 60 by using the data channel.
- the emergency call receiving organization 60 displays the received position information as, for example, a point on a map, and also displays detailed information (for example, a position in a building).
- FIG. 3 is a diagram illustrating in detail the configurations of the lighting device 10 and the portable terminal 20 that can transmit the position information shown in FIG.
- an AC voltage supplied from a power line is modulated by a modulating unit 12 with a position data signal from a position data unit 14 and supplied to an illumination light source 16.
- the illumination light source 16 emits modulated illumination light. Since this modulated illumination light changes so quickly that it cannot be detected by the human eye, it is recognized as the same as normal illumination light. When an LED is used as the illumination light source 16, it is possible to generate fast-changing illumination light modulated by position information.
- the light is received by the light receiving unit 21 directed in the direction of the illumination light, converted into an electric signal, demodulated by the demodulation unit 22, and sent to the processing unit 23. Then, this position data is transmitted from the transmission / reception unit 24 to the base station via the antenna 25.
- the light receiving section 21 can be constituted by a photo diode or the like.
- FIG. 4 is a diagram for explaining a caller's operation performed by a camera-equipped mobile phone to send position information by using the camera as a light receiving unit for position data.
- the sampling frequency of the video acquisition of the camera attached to the mobile phone needs to be sufficient to capture the change in the amount of illumination light. For example, see Nobuyuki Matsushita et al., “ID Cam: Smart Camera that Can Acquire Scenes and IDs Simultaneously,” Information Processing Society of Japan Vol.43 No.6, pp.3664-3674, (2002-12) and the like.
