Description

  The present invention relates to a mobile communication terminal and an information providing system using the portable communication terminal, and more particularly to an information providing and response / guidance system in an emergency or emergency.

  In an emergency or emergency such as a disaster, there is an urgent need to move from a dangerous place or a dangerous state to a safe place. As a guidance method for the target person, a method of guiding a moving direction using a bulletin board is conventionally known. However, there is a drawback that it becomes difficult for the person receiving the guidance to see the posted content as the user leaves the place where the bulletin board is installed, and the subject person is easily lost.

  As another method, there is a method of performing route guidance to a destination by a navigation system mounted on a car. In this case, since guidance information can be confirmed at any time, it is more reliable than the above-mentioned example. However, since a vehicle-mounted device is used, the scenes that can be used are limited to the time of boarding, and there is a problem that portability is lacking. . As a remedy for these problems, Patent Document 1 describes a method in which a target person who is the user can view guidance information while walking by using a portable information terminal.

  FIG. 8 is an explanatory diagram relating to the guiding method described in Patent Document 1. The guidance system 100 is a system that provides a guidance service to a portable information terminal (user terminal). The guidance system 100 includes a navigation server 10 and an information presentation server 20, and the navigation server 10 stores therein a user's current position, destination data, a navigation program, a communication program, and screen guidance information.

  The communication network 200 is interposed between the guidance system 100 and the portable information terminal 300, and performs wireless communication with the portable information terminal 300. Further, wired communication is performed between the guidance system 100 and the communication network 200. The communication network 200 detects the position of the mobile information terminal 300 by detecting an identification number (phone number) that the mobile information terminal 300 (mobile phone) periodically generates. Guidance information and identification information from the detected position (current position) to the next position to go to the destination are transferred from the navigation server 10 to the information presentation server 20. The information presentation server 20 extracts related information corresponding to the transferred guidance information from the database and transmits it to the portable information terminal 300.

The portable information terminal 300 is a portable information terminal capable of outputting guidance information. As guidance information guidance means (paragraph 0044), guidance means by map display or voice is disclosed.

  However, the conventional guidance system as described in Patent Document 1 uses an identification number (telephone number) that is periodically generated by the mobile phone as a means for detecting the position, so the accuracy of the position information is not fine. There is a problem. The position accuracy is determined by the size of the area of the cellular phone network (or the cells constituting the area). Specifically, the size of the cell is about 500 m in the city center and about 5 to 6 km in the suburbs. Therefore, fine guidance using this positional accuracy is not easy. In addition, there is a problem that it is difficult to grasp the positional relationship in the vertical direction, such as when there is a user in a building, and it is difficult to guide it.

  Furthermore, although not described in Patent Document 1, it is considered that the positional accuracy can be improved by using GPS. However, in this case, the mobile communication terminal needs a special function for GPS communication.

  An object of the present invention is to obtain position information by a simple method without requiring a special function, and to bring in position information with good accuracy and provide fine guidance.

A mobile communication terminal including the information processing unit, and an information server that extracts route information to a predetermined guidance destination based on the location information received from the mobile communication terminal and the emergency information and returns the route information to the mobile communication terminal. .

  In the information providing method of the present invention, the illumination device illuminates, the illumination control device controls the illumination by the illumination device and the output of the position information, the position acquisition unit of the mobile communication terminal acquires the position information from the illumination device, and the position The wireless unit of the mobile communication terminal transmits the information and the emergency information, and the information server extracts the route information reaching the predetermined guidance destination based on the location information and the emergency information received from the mobile communication terminal, and returns the route information to the mobile communication terminal Have means.

  The portable communication terminal and the information providing system of the present invention acquire position information through a position acquisition unit from an illumination device having an illumination function and a function of transmitting information. The lighting device can be easily installed in a larger quantity than a base station of a mobile phone network, and thus has an advantage that position information can be obtained with high accuracy. In addition, there is an advantage that it is possible to easily grasp the positional relationship in the vertical direction such as the number of floors inside the building. Therefore, it is possible to perform detailed guidance using the position information with such good accuracy, which can greatly contribute to evacuation in an emergency or emergency. In addition, since the position information with good accuracy is acquired through the position acquisition unit normally equipped in the mobile communication terminal, an effect such as a special function for GPS communication is not particularly required for improving the position accuracy.
