BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention changes the destination so that the user can arrive at the scheduled place input in the schedule by the scheduled time based on the data obtained by the schedule management function and the current position confirmation function. Even in advance, the time to leave the current location is automatically obtained and an alarm is set,
The present invention relates to a small electronic device having a function of giving an alarm when the departure time arrives.

[0002]

2. Description of the Related Art Due to recent remarkable improvements in semiconductor technology,
The effects of conflicting technical issues such as a large memory capacity and a low price, and a low power consumption and high speed CPU are becoming smaller.

Among these, high-performance computers have been gradually downsized, and even notebook-sized computers have appeared in them. As a low-cost computer,
Small electronic devices equipped only with specific functions such as schedule management functions, address books, and telephone directories have come into practical use in the field of personal use.

As such an example, Japanese Patent Laid-Open No. 2-3099
There is a small electronic device disclosed in Japanese Patent Publication No. 67.

[0005]

In the above-mentioned prior art, as a schedule management function for a small electronic device, for example, when there is a meeting at 11:00, an alarm is set to sound at 11:00, or a margin is calculated by oneself. The alarm is set by himself before 11:00. However, such a schedule management method does not consider the following problems.

(1) When the place where the conference is scheduled is far away from the present position, even if the alarm sounds at the time when the conference starts, it does not catch up with the conference.

(2) If the place (J point) before the meeting etc. is known and the place is far from the place (K point) where the meeting etc. are held, the process from the J point to the K point After that, it is necessary to calculate the required time in the process in advance and set the alarm by itself so that the alarm sounds at the time when the required time is subtracted from the start time of the meeting or the like.

(3) Even if the time taken from the current location to the planned location is calculated and an alarm is set, if an unexpected movement occurs from the current location, the time from the new destination to the planned location is calculated separately. Have to reset the alarm.

(4) When the destination is unknown, the time required to reach the place where the conference is held is naturally unknown, and the time to return to the place where the conference is held must be always taken into consideration.

The object of the present invention is to solve such a problem, and it is possible to reach the scheduled time by any place, at any time.
An object of the present invention is to provide a small electronic device having a secretarial function that informs when to leave the present location in advance so that a user can arrive at a scheduled place such as a meeting.

[0011]

A small electronic device according to the present invention is a schedule storage means for organizing and storing a schedule having a scheduled location, a scheduled time and an object as input data, and an absolute position for the present location. Current location measurement means,
Computation means for determining the time from the current location to the planned location and the time of departure from the current location, wireless data transmission / reception means for wirelessly transmitting data and map information for determining absolute position, large-capacity data such as map information, etc. Memory information reproducing means for reading, map display means for displaying a map around the present location, alarm setting means for sounding an alarm at a predetermined time,
A timer setting means for periodically performing each measurement and calculation means is provided.

[0012]

[Effects] Even if the present location of a person having a small electronic device equipped with the above means is far away from the planned place input in the schedule of the small electronic device, the absolute position of the present place is obtained, and then the means of transportation. In consideration of the above, the required time in each process from the present location to the planned location is obtained in advance from the data obtained from the wireless database search and the large-capacity data memory such as CD-ROM, and further arrives at the scheduled location. The time required for each journey is subtracted from the time in reverse order, the scheduled departure time at the current location is calculated, and the small electronic device is automatically set so that an alarm sounds at that time. Also, the absolute position of the current location is monitored at regular intervals, and if it is determined that there has been a large movement, a new scheduled departure time is obtained for the current location after the movement, and the alarm is reset. Thus, even if the user unexpectedly goes out, the alarm informs when to leave the new current location so that the user can arrive at the scheduled place input in the schedule by the scheduled time. In addition, it is possible to arrive at the scheduled place by the scheduled time by relying on the map around the present location displayed on the small electronic device.

Next, the operation of this small electronic device will be described with reference to FIGS. FIG. 2 is a flowchart for explaining the operation status of the small electronic device of FIG. 1, and FIG. 3 is a diagram showing an example of a schedule input to the small information device. In FIG. 3, the schedule is set as follows. .

(1) 9 minutes from the X station at the head office at point A on process P
Business meetings from time to time.

(2) From Y station to the customer at point B on the journey Q, start business negotiations from 13:00.

(3) 1 from the Z station to the factory at point C on the journey R
Meeting from 6:30.

Incidentally, the journey P from the point A to the X station is about 7
50m (about 10 minutes on foot), distance Q from point B to Y station is about 1500m (about 20 minutes on foot), distance R from point C to Z station is about 1000m (about 15 minutes on foot), X The distance from the station to the Y station is 80 km (1 hour and 25 minutes by train), and the distance from the Y station to the Z station is 50 km (1 hour and 5 minutes by train). The train timetable is shown below each station. Incidentally, it is assumed that these data are recorded as a database in a map information database system (not shown) of a large-scale computer or a CD-ROM disc accessed by wireless communication.

These schedule data are input from the input unit 203 of FIG. 2, pass through the data bus 202 under the control of the main control unit 201, are stored in the data memory 210, and are displayed on the LCD 205 through the display control unit 206. . FIG. 4 is a diagram showing an example of a schedule table displayed on the LCD 205 when the schedule example of FIG. 3 is thus input to the small electronic device.

As a situation to be explained, first, the owner of the small electronic device starts a business meeting at the head office at the point A at 9:00,
It is supposed to be 10 o'clock now. At this time, the clock counter 211 naturally indicates 10 o'clock.

Next, it is planned to have a business discussion with the customer at the point B from 13:00.
In order to arrive by time, calculate the time required for the journey from point A to point B, taking into account the departure and arrival times of trains,
You must depart Point A at 13:00 after deducting the time required for the journey and the spare time.

According to the present invention, simply by inputting a schedule into a small electronic device as shown in FIG. 4, in this case, the time of departure from the point A is automatically calculated, an alarm is set, and the departure is made. When the expected time matches the contents of the clock counter 211 indicating the current time, an alarm sounds and notifies.

The operation of the small electronic device for realizing such an intelligent function will be described below with reference to the algorithm flowchart of the present invention shown in FIG.

The step number of each item showing the following operation corresponds to the step number shown in each flow of the flowchart of FIG.

Step 101: Search whether the schedule is recorded in the data memory 210. 10
As of that time, as can be seen from FIG. 4, the next schedule for the customer at the point B is retrieved at 13:00.

Step 102: If the schedule is input as described above, the process proceeds to step 105, and conversely, the schedule is not input (cannot be searched).
In that case, the process proceeds to step 103.

Step 103: If the schedule has not been input, wait for the input of a new schedule.

Step 104: When a new schedule is input, the process returns to step 105.

Step 105: A map information database of a large-scale computer in a remote place is searched by data communication using the wireless communication I / F 209, or a database recorded in a CD-ROM is searched by the CD-ROM drive 214, B, the planned location entered in the schedule
Find the absolute position of the point.

Step 106: A navigation signal sent from a GPS satellite is received by the GPS antenna 212,
The GPS data processing unit 213 performs signal processing to obtain the absolute position of point A, which is the current location.

Alternatively, the absolute position of the present location can be obtained by wireless communication with a sign post installed on the road, as in the automobile traffic information communication system.

Step 107: From the A point to the B point, the absolute position of the B point, which is the planned site obtained in Step 105, and the absolute position of the A point, which is the current site obtained in Step 106.
Ask for the journey to the point.

The strokes obtained are shown below.

[0035] In this example schedule, first walk 750m from point A to X station of T Electric Railway, 80km by train from X station to Y station,
It is required to walk 1500m from Y station to B point.

Step 108: If the distance between the present location and the planned location is within a few hundred meters at the present time, it is not necessary to obtain the time of departure from the present location in advance, and an alarm is given a few minutes before. Just notice that you have a plan. Therefore, for example, this specific distance is 200m
Then, it is determined whether or not the travel obtained in step 107 is greater than or equal to the specific distance. If the distance is greater than or equal to the specific distance, the processing proceeds to step 110, and if not, the processing proceeds to step 109.

In this example schedule, the distance from point A to point B is 200 m or more, so step 110
Go to.

Step 109: If the travel is shorter than the specified distance, set a specified time sufficient to walk the specified distance. As an example of this case, 10 minutes is set as the specific time, an alarm is set 10 minutes before the scheduled time of the schedule, and the process proceeds to step 114 to sound the alarm.

Step 110: The required time in each process from the current position to the planned site is calculated from the process calculated in step 107. In the above example of going from the A point to the B point, the backward calculation is performed from the B point of the planned site.

Distance Q from point B to Y station is 1500m
It takes about 20 minutes on foot. Furthermore, if you allow about 10 minutes, you can reach Y station by 1 at 13:00 to arrive at point B.
I have to leave by 2:30. For that, it is necessary to check the time when the train arrives at the Y station. Here, a database of a large-scale computer to be read out by data communication using the wireless communication I / F 209 or a CD-RO.
The timetable of T Electric Railway in the database recorded on the CD-ROM is read by the M drive 214, and at 12:30.
Ask for a train to arrive at Y station a minute before. At this time, the train arriving at Y station at 12:25 is the best, and it can be seen that this train departs from X station at 11:00.

Next, the time required for the journey P from the point A to the X station in order to board the train departing from the X station at 11:00 will be calculated. Since the journey P is about 750 m, it takes about 10 minutes on foot. In addition, if you allow 10 minutes for ticket purchase, it is assumed that the process P will take 20 minutes in total, and you should depart the current point A at 10:40, which is 20 minutes less than 11:00. Good.

Step 111: As described above, the time to depart from the current location is calculated so as to arrive at the planned location by the scheduled time, but it is possible that the time to depart from the current location has already passed when the schedule was input. To be In such a case, the process proceeds to step 114 and an alarm is sounded immediately to inform that the delay has already occurred.

On the contrary, if the present time has not passed the time of departure from the present location, the process proceeds to step 112.

Step 112: An alarm is automatically set at 10:40, which is the time of departure from the present location obtained in step 110.

Step 113: Although the alarm is set at the time of departure from the present location as described above, it may be necessary to go to another place after that. In this case, if the destination is far away from the place where the alarm was originally set, it does not make sense to sound the alarm at the time originally set at the destination. Therefore, after setting the alarm, it is checked at regular intervals whether or not there is a large movement at the current location. If it is determined that there is a large movement at the current location, the process returns to step 105 and the processing from step 105 to step 113 is repeated for the current location after the movement. On the contrary, if there is no great movement in the current location, the process directly proceeds to step 114.

Step 114: 1 which is the set time
The alarm sounds at 0:40.

The above is a description of the case of going from the point A to the point B. Next, a case where the schedule of the point C is input will be described.

First, at the point A, an alarm sounding the time to go to the point B sounds, and when the owner of the small electronic device stops the alarm, the system of the small electronic device starts from the beginning of the flowchart of FIG. The operation starts except the schedule. In other words, the departure time has already been notified to the B point with an alarm, and in some cases, the schedule of the B point may be canceled and the vehicle may go straight from the A point to the next C point. The next scheduled mode is entered when the time alarm is stopped.

Step 101: After stopping the alarm that informs the time to go to the point B at the point A, the system first searches the schedule stored in the data memory 210.

Step 102: When the plan to go to the point C is found, the process goes to the next step 105.

Step 105: The planned place is the point C,
Find the absolute position of point C.

Step 106: The present location is set to point A, and A
Find the absolute position of the point.

Step 107: When the alarm is stopped, Therefore, in this schedule example, first, it is required to walk 750 m from point A to X station of T Electric Railway, 130 km by train from X station to Z station, and 1500 m from Z station to C point.

Step 108: The stroke is a specific distance 2
Since the length is 00 m or more, this step is passed to proceed to the next step 110.

Step 110: Obtain the time required for the new stroke obtained in step 107. Going from Point A to Point C Even in the above case, calculate backward from Point C at the planned site.

Distance R from point C to Z station is 1000m
It takes about 15 minutes on foot. Furthermore, if you have 10 minutes to spare, it will take Z to reach C point at 16:30.
I have to leave the station by 16:05. For that, it is necessary to check the time when the train arrives at the Z station. Here as well, wireless data communication and C
The timetable of T Electric Railway in the database is read out using the D-ROM, and the train arriving at Z station before 16:05 is requested. At this time, the train arriving at Z station at 16:00 is the most suitable, and it is understood that this train departs from X station at 13:30.

Next, in order to board the train departing from X station at 13:30, the time required for the journey P from point A to X station is calculated. Since the distance P is about 750m, it is about 1 on foot.
It takes 0 minutes. In addition, it is assumed that it takes a total of 20 minutes to complete the process P, considering the allowance time for ticket purchase etc. of about 10 minutes.
It is sufficient to depart from the current point A at 13:10, which is 20 minutes less than 3:30.

Step 111: The alarm is stopped by 1
At 0:40, the scheduled time to leave point A is 13:10. In this case, the current time is before the time to leave the current location, so the process proceeds to the next step 112.

Step 112: An alarm is automatically set at 13:10, which is the time of departure from the present location obtained in step 110.

Step 113: The alarm is set at the time of departure from the present location as described above. However, if the schedule at the point B is canceled and the work is continued at the point A, the alarm may be kept set. However, when going to point B next as originally scheduled, after setting an alarm, it is checked at regular time intervals whether or not there is a large movement to the present location. That is, the operations from step 105 to step 113 are repeated even on the way from the point A to the point B to obtain the departure time at each time and set the alarm.

In this case, although the customer arrives at the point B and has a business negotiation with the customer, the system of the small electronic device is from the point B to the point C.
Find the departure time to get to the point.

Here again, steps 105 to 11 are performed.
By the operation of 3, the stroke, the required time, and the like are obtained as follows.

[0063] Becomes

Also, in the case of going from the point B to the point C, the time required for this route is calculated back from the point C of the planned place. Itinerary R from Z station to point C
Is the same as above, so to get to point C at 16:30, you have to leave Z station by 16:05.
Therefore, if you ask for a train that arrives at Y station before 16:05, the train that arrives at Z station at 16:00 is the best, and this train leaves Y station at 14:55. It can be seen that it is.

Next, the time required for the journey Q from the point B to the Y station in order to get on the train departing from the Y station at 14:55 is calculated. It takes about 20 minutes on foot because the journey Q is about 1500m. In addition, it is assumed that it will take 30 minutes in total for the process Q, assuming about 10 minutes of time to buy tickets, etc.
At 14:25, which is obtained by subtracting 30 minutes from 14:55, the current point B may be departed. This 14
The alarm is set last at 25 minutes.

As described above, if you have a small electronic device for which a schedule has been input, no matter where you move, you can arrive at the place where you should go next by the scheduled time, so that you can arrive at the scheduled time. An alarm is automatically set, and an alarm will notify you at that time. This allows you to concentrate on your work without worrying about time or travel distance.

Further, since the train station to be boarded and the arrival / departure time of the train are known at the stage of obtaining the journey, and the train timetable is also obtained, the schedule can be changed by referring to the timetable. You can change your own behavior.

Moreover, when the train is on or off, C
The bitmap-shaped map information data recorded in the D-ROM is read into the frame memory 204, and the display control unit 20
6, a map is displayed on the LCD 205 as a bitmap, and the current location information obtained at step 106 is sent to the cursor control section 207 under the control of the main control section 201, and the cursor representing the current location is displayed on the LCD 205 through the display control section 206. Display the cursor at the current location on the displayed map. As a result, the route to the station or the route to the planned place can be known without hesitation even if the user goes to a strange place.

[0069]

[Effects of the Invention] As described above, if you have a small electronic device in which a scheduled place and a scheduled time are input as a schedule, no matter where you move, you can arrive at the next scheduled place by the scheduled time. As such, an alarm is automatically set at the time when you should leave your current location, and an alarm will notify you at that time. This allows you to concentrate on your work without worrying about time or travel distance.

[0070] Further, since the train station to be boarded and the departure and arrival times of the train are known at the stage of obtaining the journey, and the timetable of the train is obtained, the schedule can be changed by referring to the timetable. You can change your own behavior.
