Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system using a mobile communication device configured to receive a radio wave from a GPS satellite and transmit position data acquired to a base station, and the mobile communication system. Related to a communication device.

[0002]

[Problem to be Solved by the Invention] When a disaster such as a tsunami or a landslide is likely to occur, or in the event of a disaster, to call attention or evacuation to local residents living in the disaster occurrence area Has been put into practical use. This disaster prevention notification system broadcasts disaster prevention information to the resident through a loudspeaker installed in a certain area or a wireless radio receiver installed in each home.

In recent years, mobile communication devices such as PDC (Personal Digital Cellular) and PHS
(Personal Handyphone System) type mobile phones are rapidly spreading. Such a mobile phone is often carried by a user or placed very close to the user by its nature.

[0004] With the spread of such portable telephones, Japanese Patent Laid-Open Publication No. Hei 10-13938 discloses a disaster prevention report in which a central station device transmits a disaster prevention message to a portable telephone owned by a resident using a PHS. A system is disclosed. According to this disaster prevention notification system, the disaster prevention information is displayed not only by voice but also by characters or the like on the display unit of the mobile phone. In addition, when a resident of the disaster occurrence area carries a mobile phone, disaster prevention information can be reported to the resident even when the resident is out.

[0005] However, in such a disaster prevention reporting system, the party to report disaster prevention information is limited to residents in the disaster occurrence area. Therefore, if a person (non-resident) who is not resident in the disaster occurrence area is in the disaster occurrence area, even if the non-resident carries a mobile phone, the disaster prevention information is directly transmitted through the mobile phone. The disaster prevention information can only be obtained by means of hearing the disaster prevention information from the loudspeaker or transmitting the disaster prevention information from the local residents. As a result, the transmission of disaster prevention information to non-residents who have entered the disaster-prone area tends to be delayed, and there is a risk of being involved in a disaster.

[0006] On the other hand, the need to transmit information to persons in a predetermined area is not limited to a disaster. For example, in an off-limits area in a power facility (power station, substation, etc.), a monitoring device such as a camera is installed to constantly monitor whether there is an intruder in the facility.
When an intruder is found, a procedure is taken such that an administrator of the facility orders evacuation through a loudspeaker, or a guard is dispatched to take the intruder out of the facility.
However, when the facility is large or when there are various obstacles in monitoring, it takes a lot of trouble to monitor the obstacle, and there is a possibility that the intruder may be missed.

The present invention has been made in view of the above circumstances, and an object thereof is to use a mobile communication device that has been rapidly spreading in recent years, and to place it in a predetermined area such as a disaster occurrence area or a restricted area. An object of the present invention is to provide a mobile communication system that reliably detects a person and notifies the person or a person who manages the area of the person, and a mobile communication device used in the mobile communication system.

[0008]

To achieve the above object, the means described in claim 1 can be employed. According to this means, the mobile communication device obtains high-precision position data (eg, latitude, longitude, altitude) corresponding to the current position of the mobile communication device by receiving radio waves from GPS satellites. Can be. This position data is transmitted to the base station and stored in a position database provided in a base station, a control station, a communication network, or the like. The control station specifies a mobile communication device located in a predetermined area based on the position data stored in the position database, and transmits broadcast information to the specified mobile communication device. A person in the area can obtain the notification information from the mobile communication device carried by the user.

Thus, regardless of whether or not the user is a resident of a predetermined area, the broadcast information transmitted from the control station can be obtained as long as the user carries the mobile communication device. . Since the position data is obtained based on radio waves from GPS satellites, the accuracy is extremely high, and it is possible to set a very narrow area or an area having a complicated shape as a predetermined area. In addition, the notification information is not erroneously transmitted to the mobile communication device located outside the predetermined area.

According to the second aspect of the present invention, the notification information is preset and stored in the storage means at the control station, and the transmission control means reads out the notification information stored in the storage means and transmits it. Since transmission is performed to the specified mobile communication device, transmission of broadcast information can be automated.

According to the third aspect of the present invention, the voice output means of the mobile communication device outputs a message including a voice as the notification information, so that the person carrying the mobile communication device can perform the same operation as during a normal call. Thus, the notification information can be recognized.

According to the fourth aspect of the present invention, the display means of the mobile communication device displays a message including characters, graphics, symbols, and the like as the notification information, so that more detailed information and a map showing an evacuation site are displayed. Information and the like can be obtained. Further, the notification information can be easily stored, and the notification information can be transmitted to a person who is deaf.

According to the fifth aspect of the present invention, the ringer sound generating means of the mobile communication device generates a ringer sound in accordance with the control command as the notification information. It is possible to reliably recognize the reception.

According to the sixth aspect of the present invention, the vibration generating means of the mobile communication device vibrates the housing by the control command as the notification information. Even in the case of, the fact that the broadcast information has been received from the control station can be recognized.

According to the means described in claim 7, the light emitting means of the mobile communication device emits light by the control command as the broadcast information, so that it is easy to recognize that the broadcast information has been received from the control station at night or the like. Become.

According to the means described in claim 8, the broadcast information from the control station is sent to the mobile communication device as a mail, so that the owner of the mobile communication device is temporarily sent from the mobile communication device. Even when the owner may leave, the owner can later obtain the notification information accumulated as mail, and will not miss the notification information.

According to a ninth aspect of the present invention, the mobile communication device includes storage means for storing a message composed of a preset voice, and a control command as broadcast information transmitted from the control station. Is received, the message is read from the storage means in accordance with the control command and output to the audio output means. As a result, the amount of data transmitted from the control station to the mobile communication device is reduced, and the communication time is reduced. Therefore, when it is necessary to transmit the notification information to many people, such as during a disaster, the transmission of the notification information can be completed within a short time.

According to a tenth aspect of the present invention, the mobile communication device includes storage means for storing a message composed of a predetermined character or the like, and controls the broadcast as the broadcast information transmitted from the control station. When a command is received, a message is read from the storage means in accordance with the control command and output to the display means. Therefore,
As in the case of the ninth aspect, the amount of data transmitted from the control station to the mobile communication device is reduced, and the communication time is reduced.

According to the eleventh aspect of the present invention, the control station transmits the broadcast information to the fixed telephone located in the predetermined area. The notification information is transmitted via a fixed telephone to not only those who have entered temporarily, but also those who reside in the predetermined area.

According to the means described in claim 12, the control station determines whether or not the mobile communication device (that is, the carrier) exists in a predetermined area based on the position data stored in the position database. Is determined, and the result of the determination is reported to the manager of the predetermined area.The manager makes an announcement or dispatches a security guard based on the reported determination result, and It is possible to transmit information to the person carrying the mobile communication device.

According to the means described in claim 13, the control station reports to the manager not only the determination result but also information specifying the mobile communication device located in the predetermined area. In addition, the manager can directly communicate with the mobile communication device carrier within the area based on the reported information. As a result, more reliable transmission of information becomes possible.

According to the means described in claim 14, since the control station has the map database, the correspondence between the position data transmitted from the mobile communication device and the predetermined area becomes easy. For example, the latitude and longitude of the area can be determined from the area specification such as “coastal area”, and the area can be specified in various expression modes. Further, by transmitting the map data to the mobile communication device, an evacuation site, an evacuation route, and the like can be transmitted to a person who carries the mobile communication device.

According to the means described in claim 15, the predetermined area is a predetermined area or an area set in response to the occurrence of a disaster. It can be used for monitoring an intruder and evacuation recommendation to an evacuation center, evacuation advisory when a disaster may or may occur, and transmission of guidance information.

According to the mobile communication device of the present invention, the position data transmission control means controls to transmit the position data obtained based on the radio wave from the GPS satellite to the base station. The control station can accurately recognize the current position of the mobile communication device. Then, the broadcast information reception control means of the mobile communication device receives the broadcast information transmitted from the control station when the mobile station is located in the predetermined area, and the output control means outputs the received broadcast information to the output means. Therefore, the person carrying the mobile communication device can obtain the notification information via the output means.

According to the means described in claim 17, the output means of the mobile communication device is at least one of a sound output means, a display means, a ringer sound generating means, a vibration generating means, and a light emitting means. By combining these means, it is possible to more reliably obtain the notification information.
