Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a schedule management device carried by a user, and more particularly to a schedule management device having a self-position grasping function.

[0002]

2. Description of the Related Art In recent years, a schedule management device has been reduced in size and weight and has been carried by users. Such a schedule management device is known as a mobile computer. Further, an apparatus which is provided with a position grasping function based on information from a GPS satellite and is capable of managing a schedule even at a portable terminal is disclosed in, for example, Japanese Patent Laid-Open No. Hei 6-317429.

[0003] The above-mentioned mobile computer can usually set a time for which a message is to be notified. For example, when there is a meeting or the like at a remote place, the time is set in advance for the message notification. In the meantime, the message is automatically notified to the user at the time of the message notification.

[0004]

However, in the method of notifying a message at a set time by inputting by a user, for example, when a meeting or the like is performed in a remote place, 10 minutes before the start of the meeting , Or even if the user is 15 minutes away from the meeting location, the message will only be sent 10 minutes ago,
There is a problem of being late for the meeting.

[0005] Therefore, the present invention has been made in view of the above problems, and it is a technical problem to notify a user of a message at an appropriate time according to the distance to a destination.

[0006]

The technical means taken to solve the above-mentioned problems is to obtain a self-position from a position grasping function, calculate a required time from the self-position to a destination, and calculate the required time from the calculated time. , The time for message notification is variable.

[0007] With the above configuration, the schedule management device is provided with a position grasping function, so that it is possible to calculate the required time from its own position to the destination, and to notify the user of a message according to the calculated time. As a result, the user is notified of the message at an appropriate time.

In this case, if the required time is calculated based on the information of a predetermined database, an appropriate message can be notified by the database, and the time can be further ensured. This database contains maps, road speed limits, walking speeds based on geographical conditions, vehicle speeds considering road speed limits, information for calculating appropriate route combination patterns to destinations, timetables for trains, etc. If at least one of the information is stored, an appropriate message notification can be performed in consideration of various conditions.

Further, if the required time is calculated based on information from the traffic information center, it is possible to provide an appropriate notification in consideration of the traffic congestion state and the train operation state.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic block diagram of a portable schedule management device (hereinafter, referred to as a schedule device) 1. The schedule device 1 is portable to a user and has an input device I such as a keyboard or an input switch.
P, a control device (CPU) CN for performing arithmetic processing, and a storage device (database) D in which a predetermined large amount of data is stored in advance
B, a display device OM for displaying an output result (message) from the control device CN. The control device CN receives position information GI relating to a position from a GPS satellite or the like and route information CT such as traffic information. Based on this information, the control device CN calculates its own position or a destination inputted by the input device IP to obtain the destination. be able to.

FIG. 2 shows a control block diagram of the schedule device 1. The schedule device 1 manages a user's schedule (a destination, etc.). Here, how a message notification is performed when a destination (destination) is determined will be described.

The schedule device 1 inputs the time at which the user wants to be notified of the message, the method of moving to the destination, and the time at which the user arrived at the destination (10), and a memory in the control device CN. Is to be remembered.

Further, the user inputs a destination to which the user wants to go by using a keyboard or an input switch (not shown) of the input device IP (11), and calculates the destination (13). On the other hand, G
Position information such as latitude / longitude is input based on information from a PS satellite or the like (12), and its own position is calculated by a known algorithm (14). Next, a distance from the own position to the destination is calculated based on the input destination and the calculated own position. After that, based on the calculated distance, how long it takes to reach the destination is determined by the input conditions (time you want to be notified of the message, how to move to the destination, how long you want to arrive at the destination (15). For this calculation, information from the database (20) in which data is stored in advance, and necessary information transmitted from the traffic information center (30) as necessary are used.

The database used here includes information for calculating a map, a road speed limit, a walking speed based on geographical conditions, a vehicle speed in consideration of a road speed limit, an optimum route combination pattern to a destination, and the like. And information such as timetables of trains and the like. Further, the traffic information center transmits information necessary for route movement, such as traffic congestion status such as VICS information, required time to a certain point, and further operation status of a train or the like.

After calculating the required time from the own position to the destination on the basis of the information, a prior notification time is calculated for the message (18). Thereafter, the calculated advance notification time is compared with the current time (16) (17), and when the advance notification time comes, a message is notified by the display device OM (19). It should be noted that this message notification method is not limited to the display device OM, but can be transmitted by voice using a voice output device or the like.

Next, the processing of the control unit CN will be described with reference to FIG. When a power switch (not shown) of the schedule device 1 is turned on to supply power to the control device CN, the program shown in FIG. 3 is executed. First, initializing is performed in step S101. In this initializing, a necessary memory is cleared, and it is checked whether the schedule device 1 operates normally. In the input processing of the next step S102, the destination of the user and the method of moving to the destination are input from the input device IP. For example,
When you move to a place some distance away due to the meeting, the meeting place, time, message notification time,
A moving method (whether to use a walk, a car, a train, or a combination thereof) is input.

In step S103, position information, for example, latitude / longitude from a GPS satellite is input, and in step S104, its own position is calculated using a known algorithm. After that, the destination is calculated in step S105 using the map information of the database 20 to determine where the input destination (here, the meeting place) is. When the own position and the destination are calculated, Calculate the distance from your position to your destination. In step S106, a required time is obtained according to the distance. Next, in step S107, the advance notification time is calculated and obtained based on the information in the database 20, the information from the traffic information center 30, and the input message input 10, and in step S108, the advance notification time and the current time (current time) are calculated. ) And compare. Here, if the current time is before the advance notification time, the message notification is not performed, and it is determined that the notification time has not elapsed yet in step S103.
And the processing from step S103 to step S108 is repeated. However, if the current time is the advance notification time, a message notification is displayed on the display O in step S109.
Via M.

(Example 1) For example, suppose that a conference starts at exactly 15:00 at a venue called A, moves from a current position to a point A by car, and arrives at the venue 10 minutes before the conference. In such a case, the input device IP is used to input the holding time of the conference, the destination, the moving method, and how long before the arrival. After that, the own position is obtained from the position information from the GPS satellites, the point A is calculated from the map information of the database 20, the destination is calculated, and how long it takes from the own position to the point A where the conference is held is calculated.

For example, based on the information from the traffic information center 30 that it takes 20 minutes to move by car, the required time from the own position to the parking lot of the own car is calculated from the database 20 as 5 minutes. If the meeting time is 35
The advance notification time is set to notify the message minutes ago. In other words, 14 which is 35 minutes just before 15:00
The advance notification time is set so that advance notification is made when the time reaches 25 minutes. Now, if the current time is exactly at 13:00,
Since there is still enough time before the notification time, step S
No message notification is made according to the judgment of 108. Later, you move to another location. Assuming that it takes 15 minutes by car from the moved position to the meeting place for the meeting and 5 minutes from the own position to the parking lot, the message notification time is calculated,
When the current time has reached 14:30, advance notice is given.

(Embodiment 2) Next, when a train is used as a transportation method, a conference starts at exactly 15:00 at a place called "B", moves to a point B by a train, and moves to a location "B".
You want to arrive at the venue minutes ago. In such a case, the location of the conference, the method of movement, and the notification time are also input using the input device IP. Thereafter, the own position is obtained from the position information such as the latitude / longitude from the GPS satellites, the point B is calculated from the map information of the database 20, and the destination is calculated. Is calculated.

For example, if it is found from the database 20 that it takes 7 minutes on foot from the station at the station nearest to the venue and it takes 7 minutes on foot from the station to the point B of the venue, the nearest station arrives at 14:43. There is a need. Therefore, it is assumed that a train that needs to be picked up is selected from the train timetable of the database 20 and that the train that needs to be picked up departs at the nearest station at 14:20. It is calculated from the database 20 that it takes 5 minutes on foot from the current position to the station where the train is to be taken, and as a result, the time to depart is found to be 14:15. Therefore, the advance notification time is set to 14:15, the current time is always compared with the advance notification time, and a message is notified to the display device OM when the current time becomes 14:15.

[0023]

According to the present invention, in a portable schedule management device having a location grasping function, a time required from a self-position to a destination is calculated, and a time for notifying a message is calculated based on the calculated time. By making it variable, it is possible to calculate the required time from its own position to the destination, and it is possible to notify the user of a message according to the calculated time, so that the user can be Messages can be notified.

In this case, if the required time is calculated on the basis of information of a predetermined database, it is possible to ensure that an appropriate message is notified by the database in a more accurate time.

Further, if the required time is calculated based on information from the traffic information center, more appropriate notification can be made in consideration of the traffic congestion status, the train operation status, and the like.
