[2. Example of internal terminal configuration]
FIG. 2 is a block diagram illustrating an internal configuration example of the mobile phone terminal 100 according to the present embodiment. The mobile phone terminal 100 includes a control unit 101 made of a microprocessor or the like. The control unit 101 includes a control line 150 in which a control signal is transmitted or a data line 160 in which data is transmitted. Connected to each part. And the control part 101 communicates with each part through these lines, and controls operation | movement of each part.

  A communication circuit 102, a display unit 103, an operation unit 104, and a memory 105 are connected to the control line 150.

  The communication circuit 102 is a communication unit that performs wireless communication with the base station 600 (FIG. 1) for wireless telephone. That is, an antenna 106 is connected to the communication circuit 102, and the communication circuit 102 demodulates the radio wave obtained by the antenna 106 and extracts an audio signal, a video signal, and the like transmitted from the base station. Also, the audio signal transmitted from the speaker 107 that outputs the audio signal input via the data line 160 and the microphone 108 that picks up the surrounding audio and converts it into the audio signal, and the video signal controlled by the control unit 101 are displayed. Then, a process of converting to radio waves and outputting to the antenna 106 is performed.

  The display unit 103 includes a display panel formed of a liquid crystal panel and the like, and a drive unit of the display panel. The display unit 103 receives a telephone number of an incoming call, a text of an e-mail transmitted / received through the antenna 106, a camera, Is displayed.

  The memory 105 includes a ROM (Read Only Memory) and a RAM (Random Access Memory), and the memory 105 stores software necessary for controlling the mobile phone terminal 100. A program (software) necessary for communication control in the wireless LAN communication unit 131 described later is also stored in the memory 105. Further, dangerous area information described later is also stored in a predetermined area in the memory 105. Reading and writing of this dangerous area information is executed under the control of the control unit 101. The memory 105 also stores data that is temporarily generated when the control unit 101 performs control.

The wireless LAN communication unit 131 is connected to a wireless LAN communication antenna 132. The wireless LAN communication unit 131 can perform not only wireless communication through an access point but also wireless communication in an ad hoc mode, and devices directly perform wireless communication without using an access point to perform bidirectional data transfer. It is a configuration that can be performed.
The other party who performs wireless communication in the ad hoc mode in the wireless LAN communication unit 131 may be various wireless mobile terminals other than the mobile phone terminal.

The detection of the current position is performed in accordance with an instruction from the control unit 101, and the detected current position data is supplied to the control unit 101 or the like.
In the configuration of FIG. 2, the position of the terminal is detected by GPS, but the position of the terminal may be detected by other methods. For example, the position may be detected from an access point that can be received by a wireless LAN, or the position may be detected from the reception status of a signal from a base station for a wireless telephone.

[3. Example of mobile phone terminal information acquisition sequence]
With reference to the flowchart of FIG. 3, the mobile phone terminal 100 acquires dangerous area information from a database server or another mobile phone terminal, determines the validity of the acquired information, and the effective information and its own terminal An example of processing when the risk level is set from the above information will be described.

  The process of the flowchart of FIG. 3 is executed when, for example, the user of the mobile phone terminal 100 wants to obtain the latest dangerous area information, or when the data of the mobile phone terminal 100 has not been updated for a certain period of time. .

  If it demonstrates according to the flowchart of FIG. 3, it will be judged first whether the user hold | maintains dangerous area information in the memory 105 of the mobile telephone terminal 100 (step S101).

Here, the contents of the dangerous area information will be described with reference to FIG. FIG. 4 shows information in a predetermined area. The larger the area, the more dangerous area information shown in FIG.
As shown in FIG. 4, the content items of the dangerous area information include “location information (point) and error information (range)”, “danger types (multiple designation possible)”, “comment”, “risk level”, “ It consists of “terminal unique ID and registration date”. The item “location information (point) and error information (range), risk type (multiple designations possible), comment” includes information on “user of mobile phone terminal”. In addition, “cell phone terminal (automatic addition) / mobile phone terminal user” is added to the item “risk level”, and “mobile phone terminal (automatic addition)” is added to the item “terminal unique ID and registration date / time”. I'm allowed.

Returning to the description of the flowchart of FIG. 3, when the mobile phone terminal 100 holds the dangerous area information in step S101 and the dangerous area information is updated for a certain period, the process proceeds to step S102. In step S102, it is determined whether or not the latest dangerous area information is acquired.
Here, when the latest dangerous area information is not acquired, the processing here is terminated as it is. If it is determined in step S102 that the latest dangerous area information is acquired, the dangerous area information is acquired from the database server (step S103).
If it is determined in step S101 that the dangerous area information is retained and is not updated within a certain period, the dangerous area information is acquired from the database server (step S103).

  When the dangerous area information is acquired from the database server (step S103), if the database server cannot be accessed, the process proceeds to the next step without accessing. This is the case, for example, when the current position of the terminal 100 is in an area where wireless communication with the base station 600 shown in FIG. 1 is not possible.

  Then, after the processing of step 103 is performed, it is determined whether there is a mobile phone terminal capable of ad hoc communication within a range where wireless communication with the own device is possible, and the mobile phone terminal capable of ad hoc communication is determined. It is determined whether dangerous area information is stored (step S104).

  In this determination, if there is a mobile phone terminal capable of ad hoc communication within the wireless communication range, and there is dangerous area information, the transmission of the dangerous area information is requested by ad hoc communication, and the partner terminal is requested. The accumulated dangerous area information is returned and acquired (step S105). If there is no mobile phone terminal capable of ad hoc communication within the predetermined range in step S104, and if it is possible but there is no dangerous area information in the terminal, the process of step S105 is not performed.

Once the processing so far is performed, it is determined whether the dangerous area information acquired from the database server and other mobile phone terminals is information that has been acquired previously, and is valid based on the determination information set in advance by the user The dangerous area information is judged (step S106). However, the determination as to whether or not it has been acquired is whether the “terminal unique ID / registration date”, “location information / error information (range)”, and “danger type” in the dangerous area information shown in FIG. to decide. If they are equivalent, add only “comments”. If they are not equivalent, all items are registered as dangerous area information as new information.
On the other hand, when there is no mobile phone terminal capable of ad hoc communication within a predetermined range, or when there is no dangerous area information in the mobile phone terminal, it is effective based on determination information set in advance by the user. It is determined as dangerous area information (step S106).

  Note that this determination information is information in which the level in which the user considers the items “risk type” and “risk level” in the dangerous area information to be dangerous is set in advance.

  Next, the process proceeds to step S107, and the item “risk level” of the dangerous area information is recalculated from the acquired effective dangerous area information and the dangerous area information of the own terminal. As elements for recalculation, “position information + error information (range)” and “danger type” in the dangerous area information are used.

  Then, after the recalculation of the risk level is completed, the dangerous area information of each area is integrated (step S108), and the information stored in the memory 105 is updated with the integrated dangerous area information of each area. Exit.

  The recalculation process in step S107 is, for example, to set the level of risk based on the ratio of the number of dangerous area information in a specific area from the total number of dangerous area information in the specific area. . In other words, if there are multiple similar “risk types” within the “location information + error information (range)” in a given area, the risk level is set high, and the same “risk type” is set to “position”. If a plurality of information + error information (range) ”does not exist, the risk is set low.

  For example, as a ratio to the number of registered risk information in a specific area, the ratio of the number of information is 10% or more of the risk “1”, 8% or more and less than 10% of the risk “2”, 5% or more 8% Less than 2% and less than 5% are assigned a risk “4”, and 0% and less than 2% are assigned a risk “5”. FIG. 5 is a diagram showing this level setting. By doing in this way, for example, when the number of registered risk information in a specific area is 100 and the number of information in a predetermined area is 10, the ratio of the number of information is 10%. The regional risk is “1”.

  “Position information + error information (range)” means “position information” is the center of the dangerous area, and “error information (range)” is a circle range having a predetermined radius centered on “position information”. It is said. Therefore, when deciding the number of dangerous area information in a given area, a specific area is divided by a certain size, and the given area is determined from the registered points (location information) and its error information (range). The number of dangerous area information in Judgment. For example, as shown in the example of FIG. 6, the area to be managed is divided into six equal parts, and each area is divided into areas A-1, A-2, A-3, B-1, B-2, and B-3. Divide. If the location information of the registered dangerous area information 1 is A-1, but the error information (range) is A-1, A-2, B-1, B-2, the dangerous area information 1 is It becomes the information of the area of A-1, A-2, B-1, and B-2. If the registered location information and error information (range) of the dangerous area information 2 is only B-3, the dangerous area information 2 is information on the area of B-3. The number of divisions and the division state shown in FIG. 6 are merely examples.

[4. Example of entry notification sequence]
Next, an example of a notification sequence when a user having the above-described mobile phone terminal 100 enters a dangerous area will be described with reference to the flowchart of FIG. The process shown in FIG. 7 is a process performed when dangerous area information is stored in the mobile phone terminal.

  First, the user sets a notification level of the degree of danger through the operation unit 104 (step S111). That is, the user's convenience level is set as the level of “risk level” which is an item of the dangerous area information.

  Then, the own terminal is constantly monitored from the position information of the own terminal using the GPS processing unit 141 or the like (step S112). Here, it is determined from the stored dangerous area information whether or not the vehicle has entered a dangerous area that satisfies the degree of risk (step 113). When the dangerous area has been entered, the control unit 101 displays or sounds on the display unit 103. Is output to the user (step S114). Then, it returns to step S112 and always monitors. At this time, it is also possible to make a notification such as a display including “comment” and “type of danger” together.

  If it is determined in step 113 that the vehicle has not entered the dangerous area, no action is taken (step S115), and the process returns to step S112 to constantly monitor.

[5. Example of registration of dangerous area information and risk setting sequence of mobile phone terminal]
Next, an example of a sequence for registering dangerous area information of a predetermined area in the mobile phone terminal 100 will be described with reference to the flowchart of FIG.

  First, the user determines whether or not the dangerous area information of the area to be registered is registered in his / her mobile phone terminal 100 (step S201).

If the dangerous area information is not registered, the dangerous area information is registered (step S202). The contents to be registered are “location information and error information (range)”, “type of danger”, and “comment” of the area determined to be dangerous. The comment is a sentence that is freely input by the user. Furthermore, at the time of registration, the “mobile phone terminal unique ID” and the “registration date” are also added to the information (see FIG. 4).
Then, the dangerous area information list is updated (step S205).

  The newly registered dangerous area information is entered, and the “risk level” of the dangerous area information list is recalculated (step S206). As elements for recalculation, “position information + error information (range)” and “danger type” in the dangerous area information are used.

  Here, the same calculation as the recalculation process described in step S107 in the flowchart of FIG. 3 is applied to the recalculation process. For example, the risk level setting shown in FIG. 5 and the area range setting shown in FIG. Done.

  Then, the risk area information list including the recalculated risk level is reset (step S207). The above is the processing when there is no registration for a predetermined area in the dangerous area information list.

On the other hand, if it is determined in step S201 that dangerous area information has been registered, it is determined whether to change the registered dangerous area information (step S203).
If no change is made in step S203, the processing here ends.
When changing in step S203, the registered dangerous area information is updated or added (step S204). Thereafter, the process proceeds to step S205, where the dangerous area information list is updated, and the risk recalculation (step S206) and resetting (step S207) are performed.
The above is the processing when the dangerous area information list is registered for a predetermined area.

[6. Example of risk area information registration and risk level setting sequence to database server]
Next, an example of a sequence when the user having the mobile phone terminal 100 uploads the dangerous area information to the database server 700 (FIG. 1) will be described with reference to the flowchart of FIG.

First, the user operates his / her mobile phone terminal 100 to register the dangerous area information in the own terminal, and simultaneously uploads the dangerous area information to the database server (step S301).
Note that only the dangerous area information selected by the user may be uploaded as the dangerous area information uploaded to the database server at this time.

  The database server determines whether the uploaded dangerous area information is registered in the database server (step S302), and determines whether the item “risk type” in the dangerous area information is registered (step S303). )do.

If it is determined in step S302 that the dangerous area information is registered in the database server, and the item “hazard type” is registered in step S303, the dangerous area information in the database server 700 is registered. Add to the list (step S304).
If the dangerous area information is not registered in the database server in step S302, and if the item “danger type” in the dangerous area information is not registered in step S303, the uploaded dangerous area information is regarded as new information. And register (step S305).

  Then, the dangerous area information list is updated based on the information (step S306).

  Thereafter, the newly registered or added dangerous area information is entered, and the “risk level” of the dangerous area information list is recalculated (step S306). As elements for recalculation, “position information + error information (range)” and “danger type” in the dangerous area information are used.

  In the recalculation process, the same predetermined as the recalculation process described in step S107 in the flowchart of FIG. 3 is applied, and for example, the level setting of the risk shown in FIG. 5 and the area range setting shown in FIG. 6 are performed. .

  Then, the risk area information list including the recalculated risk level is reset (step S308), and the process is terminated.

  In this way, according to the present embodiment, it is possible to determine whether the dangerous area information is the latest, and when it is not the latest information, information is collected from the database server or other mobile phone terminals to obtain the latest dangerous area information. Can be obtained. Then, by recalculating the degree of danger based on the latest information, the user can always know the state of the dangerous area.

  Further, by setting the notification level of the risk level, when the own terminal enters an area having a certain risk level, the own terminal can notify the user. Accordingly, the user can immediately recognize that the user has entered the dangerous area without checking the dangerous area information with the mobile phone terminal.

  Furthermore, the dangerous area information can also be registered in the mobile phone terminal by itself, and the dangerous area information can be disclosed to a third party by uploading the dangerous area information to the database server. Thereby, it has the effect that dangerous area information can be utilized as shared information with many people.

[7. Description of modification]
In the above-described embodiment, the dangerous area information is uploaded to the database server, the dangerous area information in each terminal is updated from the uploaded information, and the risk information is also directly received from the neighboring terminals by ad hoc communication. I got local information.
