Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication system using a mobile communication device configured to transmit position data acquired by receiving radio waves from a GPS satellite to a base station, and the mobile communication device.
[0002]
[Problems to be solved by the invention]
A disaster prevention notification system has been put into practical use in order to call attention and evacuation to local residents living in the disaster occurrence area when a disaster such as a tsunami or a landslide may occur. Yes. This disaster prevention notification system reports disaster prevention information to the residents at once via a loudspeaker installed in a certain area or a radio receiver for disaster prevention installed in each home.
[0003]
Incidentally, in recent years, mobile communication devices such as PDC (Personal Digital Cellular) and PHS (Personal Handyphone System) mobile phones are rapidly spreading. Such mobile phones are often carried by users or placed very close to the users because of their nature.
[0004]
Therefore, against the background of the spread of such mobile phones, Japanese Patent Laid-Open No. 10-13938 discloses a disaster prevention notification system that uses PHS and the central office device transmits a disaster prevention message to mobile phones owned by residents. Has been. According to this disaster prevention notification system, 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 in 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, disaster reporting information is limited to residents within the disaster occurrence area. Therefore, if a person who is not resident in the disaster-affected area (non-resident) is in the disaster-affected area, even if the non-resident is carrying a mobile phone, disaster prevention information can be directly transmitted through the mobile phone. The disaster prevention information can only be obtained by means such as listening to disaster prevention information from a loudspeaker or communicating and listening to disaster prevention information from local residents. As a result, the transmission of disaster prevention information to non-residents who 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 convey information to persons in a predetermined area is not limited to when a disaster occurs. For example, in a restricted area in a power facility (power plant, 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 detected, the manager of the facility orders removal through a loudspeaker, or a guard is dispatched to take the intruder out of the facility. However, when the facility is large or there are various obstacles for monitoring, it takes a lot of trouble to monitor, and there is a possibility that an intruder may be missed.
[0007]
The present invention has been made in view of the above circumstances. The purpose of the present invention is to use a mobile communication device that has been rapidly spreading in recent years, and to identify a person in a predetermined area such as a disaster occurrence area or a restricted area. The object is to provide a mobile communication system that reliably discovers and notifies the person or person managing the area, and to provide a mobile communication device used in the mobile communication system.
[0008]
[Means for Solving the Problems]
  In order to achieve the above object, the means described in claim 1 can be employed. According to this means, the mobile communication device obtains highly accurate position data (for example, latitude, longitude, altitude) corresponding to the current position of the mobile communication device by receiving the radio wave from the GPS satellite. Can do. This position data is transmitted to the base station and stored in a position database provided in the base station, the control station, or the communication network. Based on the location data stored in this location database, the control stationDisaster occurredA mobile communication device located in a predetermined area is identified, and the specified mobile communication device is identified.Disaster relatedSince the notification information is transmitted, the person in the predetermined area can obtain the notification information by the mobile communication device carried by the user.
[0009]
  As a result, for example, regardless of whether or not a resident is in a predetermined area, as long as the mobile communication device is carried, the broadcast information sent from the control station can be obtained. Since the position data is obtained based on radio waves from GPS satellites, the accuracy is very high, and it is possible to set a very narrow area or an area having a complicated shape as a predetermined area. In addition, notification information is not erroneously transmitted to a mobile communication device located outside a predetermined area.Furthermore, since the predetermined area is an area that is set when a disaster occurs, the mobile communication system is used for evacuation advice and guidance information transmission in the event of a disaster.
[0010]
According to the means described in claim 2, the notification information is preset in the control station and stored in the storage means, and the transmission control means reads the notification information stored in the storage means and specifies it as described above Since it transmits with respect to a mobile communication apparatus, transmission of alerting | reporting information can be automated.
[0011]
According to the means described in claim 3, since the voice output means of the mobile communication device outputs a message composed of voice as the notification information, the carrier of the mobile communication device notifies in the same way as during a normal call. It becomes possible to recognize information.

According to the means described in claim 4, since the display means of the mobile communication device displays a message composed of characters, figures, symbols, etc. as the notification information, more detailed information or map information indicating the evacuation place is displayed. Can be obtained. In addition, the notification information can be easily stored, and the notification information can be transmitted to a person with hearing impairment.
[0013]
According to the means described in claim 5, since the ringer sound generating means of the mobile communication device generates a ringer sound by a control command as notification information, the carrier has received the notification information from the control station. Can be reliably recognized.
[0014]
According to the means described in claim 6, since the vibration generating means of the mobile communication device vibrates the housing by the control command as the notification information, the carrier is in the off state of the generation of the ringer sound Even so, it is possible to recognize that the broadcast information has been received from the control station.
[0015]
According to the means described in claim 7, since the light emitting means of the mobile communication device emits light by the control command as the notification information, it becomes easy to recognize that the notification information has been received from the control station at night.
[0016]
According to the means described in claim 8, since the notification information from the control station is sent as an email to the mobile communication device, the owner of the mobile communication device may temporarily leave the mobile communication device. Even in some cases, the owner can obtain the notification information stored as a mail later, and the notification information is not missed.
[0017]
According to the means described in claim 9, the mobile communication device includes a storage means for storing a message composed of a preset voice, and receives a control command as notification information transmitted from the control station. The message is read from the storage means according to the control command and output to the voice output means. Thereby, the amount of data transmitted from the control station to the mobile communication device is reduced, and the communication time can be shortened. Therefore, when it is necessary to transmit the notification information to many people at the time of a disaster, the transmission of the notification information can be completed within a short time.
[0018]
According to the means described in claim 10, the mobile communication device includes a storage means for storing a message composed of a preset character or the like, and receives a control command as broadcast information transmitted from the control station. Then, the message is read from the storage means according to the control command and output to the display means. Therefore, similarly to the means described in claim 9, the amount of data transmitted from the control station to the mobile communication device is reduced, and the communication time can be shortened.
[0019]
According to the means described in claim 11, since the control station also transmits the notification information to the fixed telephone located in the predetermined area, the mobile communication device is carried and temporarily stored in the predetermined area. In addition to those who enter, notification information is transmitted to those who live in the predetermined area via the fixed telephone.
[0022]
  Claim12According to the means described above, since the control station includes the map database, the correspondence between the position data transmitted from the mobile communication device and the predetermined area is facilitated. For example, the latitude, longitude, etc. of the area can be determined from the area designation such as “coastal area”, and the area designation by various expression modes becomes possible. Further, by transmitting this map data to the mobile communication device, the evacuation site, the evacuation route, and the like can be transmitted to the user of the mobile communication device.
[0024]

Calculate the current position (latitude, longitude, altitude). In this case, it is necessary to simultaneously receive positioning radio waves from at least four GPS satellites.
[0044]
The control circuits 11 of the mobile phones 1a and 1b transmit the position data (latitude, longitude, altitude) obtained by the position detector 13 to the base station 2a, and the control circuits 11 of the mobile phones 5a and 5b respectively The position data is transmitted to the base station 6a. These position data are stored in the position database 10 via the control station 9. In other words, the position database 10 stores accurate position data of the mobile phones 1a, 1b, ..., 5a, 5b, ... based on the positioning radio waves from the GPS satellites 8a, 8b, ....
[0045]
Next, the control processing contents of the control station 9 will be described with reference to the flowchart shown in FIG. In step S1, the control station 9 determines whether or not a disaster has occurred based on the disaster data input to the disaster data input unit 26 from each ministry and agency. In such a case (hereinafter simply referred to as a disaster occurrence), “YES” is determined, and the process proceeds to step S2. If no disaster has occurred and there is no risk of occurrence, it is determined as “NO” and step S1 is executed again.
[0046]
In step S2, the control station 9 transmits disaster prevention information such as evacuation advice and caution information based on the disaster data and the latitude, longitude, and altitude data of each region stored in the map database 27 ( The monitoring area A) is set using latitude, longitude and altitude.
[0047]
Subsequently, the control station 9 reads the installation position data of the subscriber phones 7a, 7b, 7c,... From the storage unit 28 (step S3), and the mobile phones 1a, 1b,. The position data is read (step S4).
[0048]
The control station 9 compares the latitude, longitude, and altitude of the position data with the latitude, longitude, and altitude of the monitoring area A to determine whether a subscriber telephone or a mobile phone exists in the monitoring area A. (Step S5). If the control station 9 determines that these telephones do not exist in the monitoring area A ("NO"), the control station 9 proceeds to step S1, and these telephones exist in the monitoring area A ("YES"). ), The process proceeds to step S6. In the case shown in FIG. 1, since the subscriber telephones 7a and 7c and the mobile telephones 1a and 5a exist in the monitoring area A, “YES” is determined.
[0049]
The control station 9 identifies all the subscriber phones (7a and 7c in FIG. 1) and mobile phones (1a and 5a in FIG. 1) existing in the monitoring area A in step S6, and from the storage unit 28 in step S7. Read control commands and messages to be sent. Then, the control station 9 proceeds to step S8, and transmits the control command and message to the subscriber telephones 7a and 7c and the mobile telephones 1a and 5a specified in step S6. After the transmission is completed, the process returns to step S1. In this case, control commands and messages are not transmitted to the subscriber telephone 7b and the mobile telephones 1b and 5b located outside the monitoring area A.
[0050]
In the cellular phones 1a and 5a, according to the control command transmitted from the control station 9, for example, a ringer sound is emitted from the speaker 17, the vibrator 24 vibrates, and the backlight 22b of the display 22 is turned on. When the user presses the call start key, the message of the disaster prevention information flows from the speaker 17, and the message is displayed on the liquid crystal display unit 22a. When the message includes map data such as an evacuation site, the map is displayed on the liquid crystal display unit 22a. Thereby, the mobile phone 1a, 5a can surely know the disaster prevention information such as that he / she is in the disaster occurrence area, the evacuation place and the evacuation method.
[0051]
The disaster prevention notification system of the present embodiment described above is based on the rapid spread of mobile phones in recent years, and mobile phones 1a,... Used in the system are positioning radio waves from GPS satellites 8a, 8b,. , The current position is detected accurately, and the position data is periodically transmitted to the base station 2a,. Since this position data is stored in the position database 10 and managed centrally, the control station 9 refers to the position database 10 to grasp the accurate current position of the mobile phone 1a,... In a short time. can do.
[0052]
Based on the position data stored in the position database 10, the control station 9 identifies the mobile phone 1a,... Located in the monitoring area A set as the disaster occurrence area, and the identified mobile phone 1a,. Since the disaster prevention information is transmitted to the mobile phone 1a, the carrier of the mobile phone 1a,... Can know the disaster prevention information via the mobile phone 1a,. Further, when the control station 9 cannot connect to the mobile phone 1a,..., The control station 9 can transmit the disaster prevention information as an e-mail, so that the carrier of the mobile phone 1a,. .
[0053]
In this case, since the accuracy of the position data is high as described above, even when the control station 9 sets a narrow area or a complex-shaped area as the monitoring area, the mobile phone 1a, The disaster prevention information can be reliably transmitted only to ..., and unnecessary disaster prevention information is not transmitted to the mobile phone 1b located outside the area.
[0054]
A message by text or voice is transmitted from the control station 9 to the mobile phone 1a in the monitoring area A. The message is received by the ringer sound, vibration of the casing, lighting of the backlight 22b, etc. Therefore, even when the ring tone is off or at night, the carrier can reliably receive the message.
[0055]
Further, since the control station 9 can also send a map of the evacuation place as a message to the mobile phone 1a,..., It is ensured that even if the carryer is an uninformed person in the monitoring area A. Can do.
[0056]
Further, since the control station 9 calls the subscriber telephone 7a located in the monitoring area A based on the installation position data of the subscriber telephone 7a stored in the storage unit 28, and transmits a voice message. Disaster information can be transmitted to residents in the monitoring area A without omission.
[0057]
In the control station 9, the message is stored in the storage unit 28 in advance, and the control unit 25 automatically reads out the necessary message from the messages stored in the storage unit 28 and identifies the specified mobile phone 1a. ,... And the subscriber telephones 7a,... Are configured to automatically transmit them, so that labor savings can be achieved, and the omission of reports due to human error can be prevented.
[0058]
In addition, since the control station 9 includes the map database 27, even when an area name is received as disaster prevention data from each ministry or the like, a monitoring area corresponding to the area can be set by latitude, longitude, and altitude. For this reason, the comparison with the position data designated by the latitude, longitude, and altitude is facilitated.
[0059]
  Next, an intrusion monitoring system which is a reference example related to the present inventionWill be described with reference to FIGS. 5, the same components as those in FIG. 1 are denoted by the same reference numerals, and different components will be described here.
[0060]
FIG. 5 shows a schematic configuration of the intrusion monitoring system. In FIG. 5, an area B surrounded by a two-dot chain line indicates a monitoring area such as a power facility. The monitoring area B is prohibited from entering, and for example, a television camera (not shown) is used to monitor whether or not a person has entered. In the monitoring area B or outside the monitoring area B, a management building 31 in which a manager of the facility is stationed is provided. A subscriber telephone 7d is installed in the management building 31.
[0061]
In the intrusion monitoring system, the control station 9 functioning as a monitoring center monitors whether a person carrying a mobile phone has entered the monitoring area B. Hereinafter, specific control processing contents of the control station 9 will be described with reference to the flowchart shown in FIG. In step S11, the control station 9 reads the position data of the mobile phones 1a, 1b,..., 5a, 5b,. In step S12, the control station 9 determines whether or not there is a mobile phone in the monitoring area B requested by the administrator. If the control station 9 determines that a mobile phone is not present in the monitoring area B (“NO”), the control station 9 proceeds to step S11, and a mobile phone is present in the monitoring area B (“YES”). ), The process proceeds to step S13. In the case shown in FIG. 5, “YES” is determined because the mobile phones 1 a and 5 a exist in the monitoring area B.
[0062]
In step S13, the control station 9 identifies all mobile phones (1a and 5a in FIG. 5) existing in the monitoring area B, and manages information relating to the identified mobile phones 1a and 5a, for example, telephone numbers, through the subscriber telephone 7d. Report to the person. Upon receiving this notification, the manager calls the mobile phone 1a, 5a to leave through the loudspeaker in the facility, or the monitor is dispatched. In addition, the administrator uses the telephone number notified from the control station 9 to directly talk to the mobile phone 1a, 5a mobile phone, and take measures such as ordering to leave.

In this case, it is preferable that the mobile phone 1a,... Is configured so that the position detector 13 (see FIG. 2) functions and the position data is transmitted even when the power is off. Thereby, the control station 9 can detect an intruder more reliably.
[0064]
In addition, since the accuracy of the position data is high, the mobile phone located near the boundary inside and outside the monitoring area B is not erroneously recognized. Furthermore, since the control station 9 informs the administrator of the presence or absence of an intruder and the phone number of the mobile phone, the administrator can talk to the mobile phone carrier and move away more directly. Can be ordered.
[0065]
  (No.2Embodiment)
  Next, a change was made to the disaster prevention notification system shown in the first embodiment.2The embodiment will be described with reference to FIG.
  In the disaster prevention notification system according to the present embodiment, a message by characters displayed on the liquid crystal display unit 22a of the cellular phones 1a,..., 5a,. .., 5a,... Are also stored in the storage unit 21.
[0066]
FIG. 7 is a flowchart showing the control processing contents of the control station 9. Steps S21 to S26 in this flowchart are the same processing contents as steps S1 to S6 in the flowchart shown in FIG. The control station 9 reads out control commands and messages from the storage unit 28 in step S27, and automatically transmits them to all the subscriber telephones (7a and 7c in FIG. 1) existing in the monitoring area A in step S28.
[0067]
Subsequently, the control station 9 reads out the control command from the storage unit 28 in step S29, and automatically transmits it to all mobile phones (1a and 5a in FIG. 1) existing in the monitoring area A in step S30. .
[0068]
For example, the control command transmitted in step S30 causes the mobile phones 1a and 5a to perform the following operations. That is, when receiving the control command, the control circuit 11 of the cellular phones 1a and 5a generates a ringer sound from the speaker 17 shown in FIG. 2, vibrates the vibrator 24, and further turns on the backlight 22b of the display 22. And the control circuit 11 reads the message by the character designated by the control command, or the message by the voice from the messages previously memorize | stored in the memory | storage part 21.
