DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication device used in a communication system having weather data generating means for generating time data by analyzing time data, position data and atmospheric pressure data, and the mobile communication device. The present invention relates to a communication system including a communication device.

SUMMARY OF THE INVENTION A weather forecast system comprises:
For example, barometers that measure barometric pressure are fixedly installed at multiple locations, and at a weather forecast center, pressure data measured by each barometer is collected, and the collected barometric data and position data indicating the position of each barometer are collected. By analyzing the time data and the time data, a weather forecast is made.

[0003] In this case, the size of the area for weather forecast and the accuracy of weather forecast depend on the state of the barometer. In other words, the larger the area where the barometer is installed, the wider the area for weather forecasting, and if there are many places where the barometer is installed, the pressure in many places Since data can be acquired, the accuracy of weather forecasts will increase.

When a barometer is fixedly installed, pressure data cannot be obtained in an area between two barometers that are adjacent to each other, so that the accuracy of weather forecast is inferior. Absent. Under such circumstances, the conventional weather forecast system has a problem that it is difficult to accurately perform a weather forecast for a relatively small area, that is, a local weather forecast.

The present invention has been made in view of the above circumstances, and has as its object the provision of a mobile communication device capable of accurately performing a local weather forecast and the mobile communication device. A communication system is provided.

[0006]

According to the mobile communication device of the present invention, the position data generating means generates position data indicating its own position based on a GPS satellite signal transmitted and received from a GPS satellite. Then, the atmospheric pressure data generating means generates atmospheric pressure data indicating the atmospheric pressure around itself. Further, the control means causes the weather data generating means to transmit the position data generated by the position data generating means and the atmospheric pressure data generated by the atmospheric pressure data generating means by the communication means. Then, the weather data generation means generates weather data by analyzing the time data, the position data, and the atmospheric pressure data.

In other words, according to this, the weather data generating means generates weather data by analyzing the time data held by itself, the position data and the atmospheric pressure data transmitted from the mobile communication device. In this case, since the mobile communication device moves, unlike the conventional one, the position for acquiring the atmospheric pressure data is not fixed, and thus, it is possible to accurately perform a local weather forecast. Can be.

According to the second aspect of the present invention, the time data generating means generates time data based on a GPS satellite signal transmitted and received from a GPS satellite.
The control means causes the weather data generating means to transmit the time data generated by the time data generating means via the communication means.

That is, according to this, the weather data generating means is not the time data held by itself,
The weather data is generated by analyzing the time data transmitted from the mobile communication device. In this case, the weather forecast is generated based on the fact that the accuracy of the time data generated based on the GPS satellite signal is relatively high. It can be done more accurately.

According to the third aspect of the present invention, the control means causes the display means to display position data, atmospheric pressure data or time data. That is, according to this, since the position data, the atmospheric pressure data or the time data is displayed on the display means, the user can recognize the position data, the atmospheric pressure data or the time data.

According to the fourth aspect of the present invention, the control means causes the communication means to receive the weather data generated by the weather data generation means, and causes the display means to display the received weather data. That is, according to this, the weather data generated by the weather data generating means is displayed on the display means, so that the user can recognize the weather data.

According to the mobile communication device of the present invention, the control means causes the display means to display the weather data superimposed on the map data indicating the map. That is, according to this one:
Since the weather data is superimposed on the map data indicating the map and is displayed on the display means, the user can recognize the weather data by associating the map data with the weather data.

According to the sixth aspect of the present invention, the control means causes the display means to display the weather data and the position data superimposed on the map data indicating the map. That is, according to this, the weather data and the position data are superimposed on the map data indicating the map and are displayed on the display means. Therefore, the user associates the map data with the weather data and the position data, In addition to being able to recognize data, it is also possible to recognize its own position.

According to the communication system of the seventh aspect, it is possible to accurately perform a local weather forecast.
