Problems solved by technology

However, the former is possible in a space suitable for satellite reception, but the position cannot be detected in buildings, underground passages, between buildings, canyons in mountainous areas, and tunnels.
Although the latter can determine the position within the reach of the radio wave of the mobile phone, the position accuracy is not high due to the complicated propagation of the radio wave.
Usually an error of several hundred meters, which is insufficient for emergency dispatch

Embodiment Construction

[0015] Next, embodiments of the present invention will be described using the drawings.

[0016] figure 1 Shown is a schematic configuration diagram of an embodiment of the present invention.

[0017] exist figure 1 Among them, an emergency light or a guide light (illumination device) 10 that is turned on for 24 hours emits visible light (illumination light) modulated with the information of the set position. The mobile phone 20 having a visible light sensor (such as a camera) receives the visible light and demodulates it to obtain position information. During emergency communication (for example, station 110 or 119), the obtained location information can also be added to the voice information, and the location information can also be automatically added as data communication.

[0018] Also, the form of location information transmitted from the mobile phone to the emergency notification receiving organization includes, for example, "normal address display + detailed informa...

Abstract

The object of the present invention is to correctly obtain position information of a cellular phone by using optical wireless communication which uses illuminating light. Therefor, for instance, an emergency light or a guide light (a lighting apparatus) (10) which light for 24 hours, in Fig 1, emits visible light (illuminating light) which is modulated by information of a position where it is installed. A cellular phone (20) having a visible light receiving part (for instance, a camera) can obtain the position information by receiving the visible light and demodulating it. In the case of urgent communication (for instance, dialing for police or ambulance), the obtained position information can be automatically added to audio information as data communication.

Description

technical field [0001] The present invention relates to a positional information communication device using a mobile phone, and particularly relates to a positional information communication device capable of notifying a person's position from a mobile phone in an emergency. Background technique [0002] Cellular phones are an important element supporting today's Japanese industry. There are 70 million portable telephone terminals in use in Japan. The terminal of the mobile phone does not only stop at the phone function, but also is equipped with an infrared reading device, has a camera, takes images, and performs image recognition according to different situations. Furthermore, it is also possible to provide an RF-ID cable connector. If you hold a portable terminal, you can make it have the function of a credit card, and even can make it have the function of an identity certificate according to different situations. Portable terminals have a tendency to take the position...
