The meteorological information collecting center 130 has the meteorological condition data obtained from the fixed point observation device 110 and the meteorological condition data and position data sent from the portable telephone device 120 built therein. It is stored in the memory 131.

However, the weather condition data sent from the portable telephone device 120 is not always the data acquired outdoors, but may be the data acquired indoors. Since the data acquired indoors does not accurately reflect the weather conditions, it is necessary to exclude the data acquired indoors from the weather analysis data.

Therefore, as will be described later, the weather information collection center 130 determines the weather condition data into valid data and invalid data based on the position data sent from the portable telephone device 120 together with the weather condition data. Classify,
Only valid data is stored in the memory 131.

FIG. 4 is a flowchart showing a first example of the operation of the meteorological information collecting system according to this embodiment. Hereinafter, with reference to FIG. 4, a first example of the operation of the weather information collection system according to the present embodiment will be described.

First, the user of the portable telephone device 120 connects the line to make a voice call or data communication (step A1).

At this time, each sensor 210, 220, 230 provided in the mobile phone device 120 observes the surrounding weather condition and obtains the obtained weather condition data (hereinafter, the weather condition data obtained when the line is connected). "Called line connection weather condition data") is stored in the memory built in the mobile phone device 120 (step A2).

Further, the position sensor of the mobile phone device 120 obtains the position of the device itself when the line is connected and stores it as start position data in the memory built in the mobile phone device 120 (step A3).

Then, when the user disconnects the line, each sensor 210, 2 provided in the portable telephone device 120
20, 230 are built in the mobile phone device 120 by observing the surrounding weather conditions and obtained weather condition data (hereinafter, the weather condition data obtained at the time of disconnecting the line is referred to as “the weather condition data at the time of disconnecting line”). It is stored in the memory (step A4).

Further, the position sensor of the portable telephone device 120 obtains the position of the device itself when the line is disconnected and stores it as the end position data in the memory built in the portable telephone device 120 (step A5).

Next, the portable telephone device 120 uses the weather condition data at the time of line connection and the start position data and the weather condition data at the time of line disconnection and the end position data as SMS or control information via a base station (not shown). , To the weather information collection center 130 (step A6).

The mobile phone unit 120 then disconnects the line (step A7).

The mobile phone device 120 collectively transmits the above data to the weather information collection center 130 when the line is disconnected. However, when the line is connected, the weather condition data at the time of line connection and the start position data are transmitted to disconnect the line. It is also possible to transmit the weather condition data at the time of disconnection and the end position data, respectively.

The weather information collection center 130 receives the above-mentioned data from the portable telephone device 120 (step B1) and then stores the data in the memory 131.

Next, the weather information collection center 130
In order to eliminate the weather condition data observed indoors, first, the start position data is compared with the map database 133 to determine whether or not the mobile phone device 120 was outdoors at the time of line connection, that is, the weather condition at the time of line connection. It is determined whether the data is data observed outdoors (step B2).

When the weather data at the time of line connection is the data observed outdoors (YE in step B2)
S), subsequently, similarly, the end position data is compared with the map database 133, and when the line is disconnected, the mobile phone device 12
It is determined whether 0 is outdoors, that is, whether the weather condition data at the time of disconnection is data observed outdoors (step B3).

If both the weather data at the time of line connection and the weather data at the time of line disconnection are data observed outdoors (YES in step B3), then the movement status of the mobile phone unit 120 is confirmed. . That is, it is determined whether the user of the mobile phone device 120 has been stationary or disconnected while the line is disconnected or connected (step B4).

The movement status of the portable telephone device 120 is confirmed by collating both the start position data and the end position data with the map database 133.

The first item to be checked is what the mobile phone device 120 is moving along. For example, when the mobile phone device 120 is moving along a road such as a national road on the map database 133, the mobile phone device 120.
It can be presumed that the user of is riding on a passenger car and is moving. Alternatively, when the mobile phone device 120 is moving along the track, it can be estimated that the user of the mobile phone device 120 is on the train and is moving.

The second confirmation item is the moving speed. That is, it is confirmed how long the mobile phone device 120 is moving and how long the mobile phone device 120 is moving. As a result, it is possible to estimate whether the user of the mobile phone device 120 is moving on foot or by transportation such as a passenger car or train. For example, the walking speed of humans is 4 to 5 km / hour at the maximum. Therefore, when the mobile phone device 120 is moving at that speed, it can be estimated that the user of the mobile phone device 120 is walking. When the mobile phone device 120 is moving at a speed of 20 to 30 km / h,
It can be estimated that the user of the mobile phone device 120 is traveling by car or train.

By comparing both the start position data and the end position data with the map database 133, it is determined that the weather information collecting center 130 indicates that the user of the mobile phone device 120 is stationary or moving on foot. When the determination is made (YES in step B4), the weather information collection center 130 stores both the weather data at the time of line connection and the weather data at the time of line disconnection in the weather database 133.
(Step B5).

If the user of the mobile phone device 120 does not stand still and is not moving on foot (step B
4 NO), the weather information collection center 130 determines that both the line connection weather condition data and the line disconnection weather condition data are invalid data and deletes them without registering them in the weather database 133 (step B6).

When the cellular phone device 120 is indoors at the time of line disconnection, that is, when the weather condition data at the time of line disconnection is data observed indoors (N in step B3).
O), the weather information collection center 130 is the mobile phone device 12
It is determined whether the user of 0 is stationary or disconnected while the line is disconnected or connected (step B7).

By comparing both the start position data and the end position data with the map database 133, it is determined that the weather information collecting center 130 indicates that the user of the mobile phone device 120 is stationary or moving on foot. When the determination is made (YES in step B7), the weather information collection center 130 registers only the weather condition data at the time of line connection in the weather database 133 (step B8).

If the user of the portable telephone device 120 does not stand still and is not moving on foot (step B
No. 7), the weather information collection center 130 determines that both the line connection weather condition data and the line disconnection weather condition data are invalid data and deletes them without registering them in the weather database 133 (step B6).

When the line connection weather condition data is the data observed indoors (NO in step B2),
Then, similarly, the end position data is stored in the map database 1
In comparison with 33, it is determined whether or not the mobile phone device 120 is outdoors when the line is disconnected, that is, it is determined whether or not the weather condition data at the time of line disconnection is data observed outdoors (step B9). .

If the weather condition data at the time of disconnection is data observed outdoors (YES in step B9),
The weather information collection center 130 determines whether or not the user of the mobile phone device 120 is stationary or disconnected between the line disconnection and the line connection (step B10).

By comparing both the start position data and the end position data with the map database 133, it is determined that the weather information collection center 130 indicates that the user of the mobile phone device 120 is stationary or is moving on foot. If determined (YES in step B10), the weather information collection center 130 registers only the weather condition data at the time of disconnection in the weather database 133 (step B1).
1).

If the user of the mobile phone device 120 does not stand still and is not moving on foot (step B
No. 10), the weather information collection center 130 determines that both the line connection weather condition data and the line disconnection weather condition data are invalid data and deletes them without registering them in the weather database 133 (step B6).

If the weather condition data at the time of disconnection is data observed indoors (N in step B9).
O), both the line connection weather condition data and the line disconnection weather condition data are data observed indoors, so the weather information collection center 130 determines that both weather condition data are invalid, Database 13
It is deleted without registering in 3 (step B6).

As described above, in the meteorological information collecting system according to the first embodiment of the present invention, the portable telephone device 1
The weather condition data when 20 is determined to be indoors both when the line is connected and when the line is disconnected, and the weather condition that is expected to be observed when the mobile phone device 120 moves by train, bus, car, etc. All data and other meteorological condition data that are considered to be observed under the environment affected by artificial factors are excluded, and only valid meteorological condition data is registered in the meteorological database, that is, the memory 131.

According to the meteorological information collecting system of this embodiment, the following effects can be obtained.

The first effect is that more accurate and reliable provision of weather information can be provided.

Conventionally, the weather condition data of the area where the fixed point observation device is not provided can be predicted only from the weather condition data obtained from the surrounding fixed point observation devices. However, according to the meteorological information collecting system according to the present embodiment. For example, the sensors 210, 220, 23 of the mobile phone device 120 in that area
Since it becomes possible to use the weather condition data observed by 0, it is possible to provide more accurate weather information.

The second effect is that a precise weather information observation network can be constructed at low cost.

Since the mobile phone device is widely used nowadays, it is possible to easily cover almost the entire area to be observed by attaching a weather condition observation sensor to the mobile phone device.

The third effect is that for areas where more detailed information is required (such as downtown areas and tourist spots where people are concentrated),
It is possible to provide more precise information.

Higher precision weather information is required in areas where people are concentrated, but more mobile phone devices are concentrated in areas where people are concentrated, so more information can be collected. Therefore, more weather condition data can be collected.

FIG. 5 is a flowchart showing a second example of the operation of the meteorological information collecting system according to this embodiment. Hereinafter, with reference to FIG. 5, a second example of the operation of the meteorological information collecting system according to the present embodiment will be described.

In the example of the operation of the meteorological information collecting system according to this embodiment shown in FIG. 4, regardless of the area,
The weather condition data is collected from the mobile phone devices 120 scattered in various places to the weather information collection center 130.
In some cases, the traffic of the network is unnecessarily increased, which may affect the function of the original mobile phone device. Therefore, it is possible to prevent unnecessary weather condition data from flowing to the network by designating an area that needs the weather condition data in advance. In the second example described below, an area is designated in advance, and the weather condition data is transmitted only from the mobile phone device 120 located in the designated area.

As shown in FIG. 5, first, the weather information collection center 130 transmits area designation information indicating an area requiring observation to the base station 520 (step D).
0).

Next, the base station 520 transmits the area designation information only to the portable telephone device 120 located in the area requested by the weather information collecting center 130, with respect to the portable telephone device 120 trying to connect the line. (Step E
1).

The mobile telephone device 120 connected to the line (step A1) first determines whether or not the area designation information is transmitted from the base station 520 (step C).
1).

When the area designation information has not been transmitted from the base station 520 (NO in step C1), steps A2 to A6 are executed similarly to the first example described above, and then the line is disconnected (step A7).

When the area designation information is transmitted from the base station 520 (YES in step C1), the mobile telephone device 120 determines whether its own device is located within the area designated by the area designation information. It is determined whether or not (step C2).

When the mobile phone device 120 is not located in the area specified by the area specifying information (NO in step C2), the mobile phone device 120 disconnects the line without collecting and transmitting the weather condition data ( Step A7).

On the other hand, when the portable telephone device 120 is located in the area designated by the area designation information (YES in step C2), the steps A2 through A2 are performed as in the first example. After executing A6, the line is disconnected (step A7).

The weather information collecting center 130 receives each data from the portable telephone device 120 (step B).
1) Store those data in the memory 131.

Then, as in the first example, step B2
Through step B11 is executed.

According to the above-mentioned second example, the information collection center 130 pre-designates an area requiring weather observation, and the weather information collection center 130 is located in the designated area. Receive weather condition data from only. Therefore, it is possible to prevent unnecessary increase in network traffic.

In order to improve the accuracy of meteorological observation by the meteorological information collecting system according to this embodiment, the following operation can be additionally performed in addition to the above-mentioned first and second operation examples. .

FIG. 6 is a flowchart of the first additional example for improving the accuracy of meteorological observation.

[0110] The weather information collection center 130 receives the line connection weather condition data and the line disconnection weather condition data from the mobile phone device 120, and then the mobile phone device 120 concerned.
The weather condition data (hereinafter referred to as "peripheral data") is received from the fixed-point observation device 110 that is close to the mobile phone device 120 or another mobile phone device that is close to the mobile phone device 120 (step F1).

Next, the line connection weather condition data and the line disconnection weather condition data received from the portable telephone device 120 are compared with the peripheral data, and the difference between the two data is obtained (step F2).

Then, it is judged whether or not the difference between the two data is smaller than a predetermined threshold value (step F
3).

When the difference between the weather condition data and the peripheral data is smaller than a predetermined threshold value (step F
No of 3), the meteorological information collection center 130 determines the meteorological condition data as valid data and registers it in the meteorological database 133 (step F4).

If the difference between the weather condition data and the peripheral data is larger than a predetermined threshold value (step F
(YES of 3), the weather condition data transmitted from the mobile phone device 120 is considered to be the weather condition data that has received some human factor such as in a car in a traffic jam or in an arcade. The center 130 determines that the weather condition data is invalid data and deletes it without registering it in the weather database 133 (step F
5).

For example, the temperature indicated by the weather condition data is 24
If the temperature indicated by the plurality of surrounding data is 30 degrees, the user of the mobile phone device 120 can estimate that the user is in the room in which the cooling device is operating. Therefore, by deleting such weather condition data,
The accuracy of meteorological observation can be further improved.

The fixed-point observation device 110 or another mobile phone device in the vicinity of the mobile phone device 120 is, for example, the fixed-point observation device 110 or another mobile device existing within a radius of 1 km around the mobile phone device 120. It is a telephone device. The meteorological information collection center 130 can arbitrarily set the distance that serves as a criterion for determining whether or not they are close to each other.

FIG. 7 is a flow chart of a second additional example for improving the accuracy of meteorological observation.

The weather information collecting center 130 receives the position data from the mobile phone device 120 (step G).
1) referring to the map database 133 (step G
2) It is determined whether or not the mobile phone device 120 is located in a residential area (step G3).

When the mobile phone device 120 is located in a residential dense area (YES in step G3), the weather condition data transmitted from the mobile phone device 120 is affected by an artificial element. Therefore, the meteorological information collection center 130 determines that the meteorological situation data is invalid data, and the meteorological database 133
It is deleted without being registered in (step G4).

When the mobile phone device 120 is not located in a residential area (NO in step G3), the weather condition data transmitted from the mobile phone device 120 is affected by an artificial element. Therefore, the weather information collection center 130 determines that the weather condition data is valid data and registers it in the weather database 133 (step G5).

The criteria for determining whether or not the area is a residential area can be arbitrarily set by the weather information collection center 130.
For example, 60 within any one square kilometer of an area.
If there is a home of 0 square meters or more, the area can be certified as a residential area.

FIG. 8 is a flowchart of the third additional example for improving the accuracy of meteorological observation.

The weather information collection center 130 obtains the weather condition data together with the light amount data indicating the amount of ambient light measured by the digital camera provided in the mobile phone device 120 (step H1).

As shown in FIG. 9, the meteorological information collection center 130 has a built-in data table showing the relationship between each time from 0:00 to 24:00 and the average light intensity at that time. When the light intensity data is received, the mobile phone device 120 detects the average light intensity at the time when the light intensity data is transmitted (step H2), and compares the average light intensity with the light intensity indicated in the light intensity data (step H3).

If the absolute value of the difference between the two is smaller than the predetermined threshold value (YES in step H4), the weather information collection center 130 determines that the weather condition data is valid data, and the weather database It is registered in 133 (step H4).

When the absolute value of the difference between the two is larger than a predetermined threshold value (NO in step H4), the weather information collection center 130 determines that the weather condition data is invalid data, and the weather database It is deleted without registering in 133 (step H5).

For example, even if it is nighttime, if the light quantity shown in the light quantity data is higher than the average light quantity, there is a high possibility that the building is equipped with lighting equipment. On the contrary, if the light amount shown in the light amount data is lower than the average light amount even during the daytime, there is a high possibility that the light amount is inside an underground mall or a building.

Therefore, it is possible to estimate whether the user of the mobile phone device 120 is indoors or outdoors by comparing the light amount shown in the light amount data sent from the mobile phone device 120 with the average light amount. You can

Since the light quantity changes depending on the season, the data table as shown in FIG. 9 can be changed as necessary.
