Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to position specifying for specifying the position of a moving body such as a moving vehicle or a person, and in particular, it is mounted on a moving body and the position information obtained by detecting its own position is externalized. The present invention relates to a position information transmitting device, method, and program for transmitting to a user.

[0002]

2. Description of the Related Art In recent years, GPS (Global Positioning Sys
tem: global positioning system), PHS, mobile phone base station information, and other means that can detect the position, and a position specifying system that specifies the position of a moving body such as a moving vehicle or a person is used. For example, the mobile device is equipped with a device equipped with GPS (client device), the client device detects its own position, and the obtained position information is transmitted to a device (server device) in another location. The position of the moving body is specified.

In such a system, position information is transmitted from the client device to the server device at a predetermined frequency. In order to improve the accuracy of position identification, it is preferable that the transmission frequency is high, but since the transmission cost becomes high, the position information is actually transmitted every time a predetermined time elapses or the mobile body moves a predetermined distance. Has been done.

However, if the transmission frequency of the position information is simply determined only by the passage of time or the moving distance, the number of the position information that can be obtained may vary depending on the moving condition of the moving body, or the position information may be excessively transmitted. There is a problem.

[0005] For example, in the case of a client device set to send position information every minute, 30 km /
For a moving body traveling at h and a moving body traveling at 60 km / h, the distance between the positions specified for each transmission is 2
Twice different.

FIG. 8 shows the above situation, and is a schematic diagram showing the search results displayed on the display of the operator who performs the position search. The movement history of the moving body is displayed on the map. On a moving body running at 30 km / h, the position transition is displayed at small intervals (Fig. 8 (a)), but 60
In a moving body traveling at km / h, the interval becomes large (FIG. 8 (b)), and the number of pieces of position information that can be acquired within a fixed distance decreases. This situation becomes more remarkable as the traveling speed becomes higher. On the contrary, when the speed is low in an urban area, the display is as shown in FIG. This results in excessive transmission of position information even with a short travel distance, and communication costs are wasted.

For the problem as shown in FIG. 8 (c), it is considered that the setting of transmitting the position information for every predetermined traveling distance is effective, but this setting also has a problem. For example, in the case of a client device that is set to transmit position information every 1 km of mileage, for example, if the mobile body is mostly detained due to traffic jam, the position information will not be transmitted for a long time, so the server device When the position information cannot be acquired and the vehicle is traveling at an extremely high speed on a highway or the like, the communication cost is wasted because it is frequently transmitted.

[0008]

As described above, if the predetermined frequency elapses or only the predetermined movement distance is used as the reference for the frequency of transmitting position information, the number of position information that can be acquired varies depending on the moving speed of the moving body. However, communication costs are wasted.

Further, in recent years, there is known a system for specifying the position of a mobile body based on the position information already acquired by the server device when the position information from the mobile body cannot be acquired due to the bad radio wave condition. In such a system, the current position of the mobile body is estimated from the history of a plurality of pieces of position information already acquired before the position information from the mobile body is lost, so the number of pieces of position information that can be acquired varies depending on the moving state of the mobile body. Then, accurate position estimation cannot be performed,
There is a problem that the estimation accuracy becomes poor.

Therefore, the present invention has been made in view of the above circumstances, and the frequency of transmission of its own position information is changed according to the moving state of the moving body so that the server apparatus always keeps the same regardless of the moving state of the moving body. An object of the present invention is to provide a position information transmitting device, method, and program capable of acquiring position information.

In the case of 60 km / h or more, the process branches to the step during high-speed traveling, and the position information is transmitted every 1 km of traveling distance. In step S103, the traveling distance is determined, and if it has not reached 1 km, the process directly proceeds to step S112. In this case, since the transmission is not performed, the process proceeds to step S114 for determining whether or not the vehicle is traveling at an ultra low speed. In this case, since the vehicle is traveling at high speed, return to step S101 again
The th own vehicle position information is recorded in the history data storage unit 18. As a result, the history data storage unit 18 is initially (0
Second) and the second (1 second later) own vehicle position information is recorded. The same procedure is repeated to store a plurality of vehicle position information. When the mileage reaches 1 km in step S103, the information accumulated in the history data accumulating unit 18 is transmitted (step S104). In step S112,
Since the transmission is completed, the process proceeds to step S113 to clear the data in the history data storage unit 18. After that, the procedure returns to step S101 again, and the same procedure is repeated, and
Send 3 times.

When the vehicle speed is 30 km / h or more and less than 60 km / h, the process branches to the step for medium speed running, and the running time is 6
The position information is transmitted every 0 seconds. Step S
In 105, the traveling time is determined, and if it has not reached 60 seconds, the process directly proceeds to step S112. In this case, since the transmission is not performed, the process proceeds to step S114 for determining whether or not the vehicle is traveling at an ultra low speed. In this case, since the vehicle is traveling at medium speed, the process returns to step S101 again and the second vehicle position information is recorded in the history data storage unit 18.
As a result, the history data storage unit 18 is initially (0 second)
Then, the second (1 second later) own vehicle position information is recorded. The same procedure is repeated to store a plurality of vehicle position information. When the traveling time reaches 60 seconds in step S105, the information accumulated in the history data accumulating unit 18 is transmitted (step S106). In step S112, since the transmission is completed, the process proceeds to step S113, and the data in the history data storage unit 18 is cleared. After that, the process returns to step S101 again, and the same procedure is repeated to perform transmission twice, three times.

When the vehicle speed is 10 km / h or more and less than 30 km / h, the process branches to the step for low speed running, and the running time is 4
The position information is transmitted every 0 seconds. Step S
In 107, the traveling time is determined, and if it has not reached 40 seconds, the process directly proceeds to step S112. In this case, since the transmission is not performed, the process proceeds to step S114 for determining whether or not the vehicle is traveling at an ultra low speed. In this case, since the vehicle is traveling at a low speed, the process returns to step S101 again and the second vehicle position information is recorded in the history data storage unit 18.
As a result, the history data storage unit 18 is initially (0 second)
Then, the second (1 second later) own vehicle position information is recorded. The same procedure is repeated to store a plurality of vehicle position information. When the traveling time reaches 40 seconds in step S107, the information accumulated in the history data accumulating unit 18 is transmitted (step S108). In step S112, since the transmission is completed, the process proceeds to step S113, and the data in the history data storage unit 18 is cleared. After that, the process returns to step S101 again, and the same procedure is repeated to perform transmission twice, three times.

When the vehicle speed is less than 10 km / h, the process branches to the step for ultra-low speed traveling, and the position information is transmitted every 20 seconds of the traveling time. However, when running at ultra-low speed,
Since the vehicle may stop, the vehicle position information first recorded in the history data storage unit 18 is transmitted in step S109 before the traveling time is determined. Next, in step S110, the traveling time is determined, and if it has not reached 20 seconds, the process directly proceeds to step S112. In this case, since the transmission is not performed after step S110, it is determined whether or not the vehicle is traveling at an ultra-low speed in step S114.
Go to. In this case, since the vehicle is traveling at an extremely low speed, the process proceeds to step S115, and the second vehicle position information is temporarily recorded in the history data storage unit 18. As a result, the history data storage unit 18 records the initial (0 second) and the second (1 second later) own vehicle position information. Then, again in step S11
The traveling time is judged at 0. The same procedure is repeated to store a plurality of vehicle position information. Then, when the traveling time reaches 20 seconds in step S110, the history data storage unit 18
The information stored in (1) is transmitted (step S111). In step S112, since the transmission is completed, step S1
In step 13, the data in the history data storage unit 18 is cleared. After that, the process returns to step S101 again, and the same procedure is repeated to perform transmission twice, three times.

The flow of each branching step has been described above. When the vehicle speed is successively measured and the vehicle speed is equal to or higher than a predetermined speed (high speed running), the transmission frequency is set based on the distance reference D1 according to the vehicle speed. However, when the vehicle speed is less than a predetermined speed (super-low speed traveling to medium speed traveling), the time reference T1 according to the vehicle speed,
By setting the transmission frequency based on T2 and T3, an appropriate transmission frequency is determined according to the change in vehicle speed.
