The block diagram which showed the tracker system which concerns on Embodiment 3 for carrying out an invention. FIG. 6 is a schematic diagram showing a display screen displaying a plurality of display modes downloaded from a management device by a terminal in the tracker system according to the first to third aspects for carrying out the invention.

The tracker system according to the first embodiment for carrying out the invention shown in FIG. 1 includes a tracker device 10, a management device 20, and a terminal 30.

The tracker device 10 includes a step sensor 11, a control unit 12, a GPS positioning unit 13, a wireless communication unit 14, a set distance information 15, a battery 16, and a power switch 17. Then, the power switch 17 is turned on by a person, and the step sensor 11, the control unit 12, the GPS positioning unit 13, and the wireless communication unit 14 start operating with the power supplied from the battery 16.

Then, the step sensor 11 outputs the detected steps per unit time to the control unit 12, and the control unit 12 multiplies the detected steps input from the step sensor 11 by the stride to obtain the movement distance (input from the step sensor 11). It corresponds to the step of obtaining the movement distance information 22 as the movement distance by multiplying the detected number of steps by the stride length).

Every time the travel distance information 22 corresponding to the calculated travel distance reaches the set distance information 15 stored in advance in a storage unit (not shown) of the tracker device 10, the control unit 12 reaches the GPS positioning unit 13. GPS position information 21 that outputs a signal and is positioned as absolute position information of the tracker device 10 based on radio waves received from GPS satellites not shown by the GPS positioning unit 13, travel distance information 22 as the calculated travel distance, and detection. The number of steps is updated from the wireless communication unit 14 to the management device 20 via the base station 40 and the Internet 41 (every time the requested travel distance information 22 reaches the set distance information 15, the GPS positioning unit 13 is transmitted from the GPS satellite. Corresponding to the step of updating the GPS position information 21 and the calculated travel distance information 22 positioned as absolute position information of the tracker device 10 based on the received radio wave to the management device 20).

The set distance information 15 is information set at a distance greater than or equal to the movable distance of the tracker device 10 by a person at the positioning interval of the GPS positioning unit 13, and is, for example, general positioning of the GPS positioning unit 13. Assuming that the interval is 1 minute, the distance is set to be longer than the general movement distance that a person can move during the positioning interval. As a result, the positioning interval in the GPS positioning unit 13 becomes longer than the general positioning interval, and as a result, the power consumed by the GPS positioning unit 13 is reduced, and the power consumption of the battery 16 mounted on the tracker device 10 is reduced. Can be reduced.

It is embodied as an operation by application software that constitutes a program for a computer (not shown).

The management device 20 is composed of a server connected to the Internet 41, and GPS position information 21, travel distance information 22, and map information 23 are stored in a storage unit (not shown) of the management device 20. The GPS position information 21 and the moving distance information 22 are information updated from the tracker device 10 each time the calculated moving distance information 22 reaches the set distance information 15, for example. The map information 23 is information created by the Geographical Survey Institute or the like and stored in advance in a storage unit (not shown) of the management device 20.

When the user of the terminal 30 performs a download operation to the operation unit 31 of the terminal 30 in the state where the GPS position information 21, the movement distance information 22, and the map information 23 are stored in the management device 20 as described above, the operation is performed. A signal is transmitted from the terminal 30 to the management device 20 via the Internet 41, and the management device 20 downloads the GPS position information 21, the travel distance information 22, and the map information 23 to the terminal 30 via the Internet 41 and immediately. The display is superimposed on the display unit 32 of the terminal 30 in a similar form. The user can view and view the GPS position information 21, the moving distance information 22, and the map information 23 superimposed and displayed on the display unit 32.

That is, in the tracker system shown in FIG. 1, the control unit 12 of the tracker device 10 calculates the movement distance by multiplying the number of detected steps per unit time acquired from the step sensor 11 by the stride length, and obtains the calculated movement distance as the calculated movement distance. Every time the moving distance information 22 of the above reaches the set distance information 15, the control unit 12 controls the GPS positioning unit 13, and the GPS position information 21 positioned by the GPS positioning unit 13 is output to the management device 20.

In addition to the hard type composed of the device, the step sensor 11 may be a soft type that detects the shaking of a person as the number of steps by application software stored in a storage unit (not shown) of the tracker device 10.

Further, the acceleration sensor may be used as the step number sensor 11, and the shaking detected by the acceleration sensor may be detected as the number of steps per unit time.

As the stride used when the control unit 12 calculates the movement distance, a stride as a constant such as 0.8 meters is stored in advance in a storage unit (not shown) of the tracker device 10, and the storage unit stores the stride length as a constant. It is also conceivable to use the stride as a memorized constant.

Alternatively, as the stride used when the control unit 12 calculates the movement distance, the user provides a stride calculation unit in the tracker device 10 and the user starts the operation with the electric power supplied from the battery 16. The tracker device 10 was carried around, the step sensor 11 repeatedly output the detected number of steps per unit time to the stride calculation unit and save it, and the step number sensor 11 accumulated the average number of cumulative detected steps saved repeatedly. It is also conceivable to divide by the average number of steps and store the stride per step in a storage unit (not shown) of the tracker device 10 for use.

Alternatively, the tracker device 10 is provided with an input unit (not shown), an input device (not shown) is connected to the input unit, and the user of the tracker device 10 inputs the stride length from the input device to the input unit to tracker. It is also conceivable to store the device 10 in a storage unit (not shown) and use the stride length of each user stored in this storage unit. As the input device, a GUI (abbreviation of graphic user interface), voice, or the like may be used.

Further, when the moving distance information 22 reaches the set distance information 15, if the GPS positioning unit 13 has poor reception sensitivity of radio waves from GPS satellites and the GPS positioning unit 13 cannot position the GPS position information 21. , The control unit 12 uploads the movement distance information 22 calculated together with the previous GPS position information 21 stored in the storage unit (not shown) of the tracker device 10 instead of the GPS position information 21 to the management device 20. As a result, the terminal 30 downloads from the management device 20 and superimposes on the display unit 32 whether or not the movement distance information 22 may have been moved from the previous GPS position information 21. can do. As a result, although the moved position of the tracker device 10 is not more accurate than the GPS position information 21, a person who sees the display unit 32 of the terminal 30 can grasp how much the tracker device 10 has moved.

A mode in which the range moved by the movement distance from the previous GPS position information 21 downloaded from the management device 20 by the terminal 30 is superimposed on the display unit 32 and displayed will be described with reference to FIG. In FIG. 2, on the map screen displayed on the display unit 32 by the terminal 30, one centering on the positioning point 33 based on the previous GPS position information 21 and having the moving distance information 22 calculated according to the number of steps as the radius 34 . Circle 35 is displayed. As a result, a person who sees the display unit 32 of the terminal 30 can easily estimate the moving range of the tracker device 10.

In the tracker system according to the second embodiment for carrying out the invention shown in FIG. 3, the association information 24 is provided in the management device 20. The association information 24 is stored in the storage unit of the server constituting the management device 20, and is based on the Cell ID as an identifier for identifying the base station 40 and the installed latitude and longitude of the base station 40 corresponding to the Cell ID. The relationship with the location information is defined, and the relationship between the BSSID as an identifier that identifies one wireless LAN access point and the location information according to the latitude where the wireless LAN access point corresponding to the BSSID is installed is defined.

Using FIG. 4, instead of the positioning point 33 of the previous GPS position information 21 downloaded from the management device 20 by the terminal 30 in the tracker system shown in FIG. 3, the position information by Cell ID or BSSID is used as the previous positioning point. A case where the range 33 is set and the range moved by the moving distance from the positioning point 33 is superimposed on the display unit 32 and displayed will be described. In FIG. 4, the terminal 30 downloads the position information by the Cell ID or BSSID corresponding to the previous positioning point 33 from the association information 24 of the management device 20.

Since the downloaded position information is less accurate than the positioning point 33 based on the GPS position information 21, the position information based on the downloaded Cell ID or BSSID is displayed on the map screen displayed on the display unit 32 by the terminal 30. displays one circle 36 centered on the positioning point 33 of 21, the radius of the distance 34 only spaced outwardly moving distance information calculated in accordance with the number of steps from one circle 36 the displayed one circle 36 The sum of and is displayed as one circle 37 centered on the positioning point 33 based on the GPS position information as the radius. As a result, a person who sees the display unit 32 of the terminal 30 can easily estimate the moving range of the tracker device 10.

Depending on the detected movement direction, the estimated range as the movement distance calculated according to the number of steps from the previous positioning point can be corrected. For example, when it is detected that the player has moved 20 steps in the northeast direction and then 10 steps in the southeast direction, one circle 35 shown in FIG. 2 and one circle 37 shown in FIG. 4 are the previous positioning points 33 or 36. A logic is conceivable in which the distance of 10 steps is set as the radius of one circle.

Since the direction may fluctuate depending on how the user holds the tracker device 10, an operation unit (not shown) for setting the operation of the moving direction sensor to be on or off is provided on the tracker device 10. An operating unit (not shown) may be set on or off by the user.

Further, the control unit 12 applies a correction coefficient of a value smaller than 1.0 to the moving distance to reduce the radius 34 corresponding to the moving distance at a constant rate so that the correction by the moving direction sensor 18 is not too effective. It is also conceivable to display one circle 35 shown in FIG. 2 or one circle 37 shown in FIG. 4 in a small size by making such corrections. In addition, the color of one circle is corrected by the movement direction sensor 18, and when the movement direction sensor 18 detects high-speed movement for a certain period of time or longer by getting on a vehicle or the like, or when the reliability of the accuracy of the number of steps is low, the color of one circle. Or the line type may be changed, or characters or icons may be displayed. Further, the color and line type of one circle may be changed and characters, icons, etc. may be displayed. Further, when the control unit 12 detects from the detection value of the movement direction sensor 18 that the user carrying the tracker device 10 is running, the control unit 12 is the sum of the movement distance 34 and the radius of one circle 36. and multiplying the correction coefficient of 1.0 or more to the radius which corresponds, one circle 35 or a circle 37 may be displayed larger as shown in FIG. 4 shown in FIG.

FIG. 6 shows one circle 35 centered on the positioning point 33 based on the previous GPS position information 21 shown in FIG. 2 and having a radius 34 of the movement distance calculated according to the number of steps, and the Cell ID shown in FIG. Alternatively, the position information by BSSID is displayed as one circle 36 centered on the positioning point 33 of the GPS position information 21, and the travel distance information calculated according to the number of steps is separated from the displayed circle 36 to the outside. In a state where the radius corresponding to the sum of the distance 34 and the radius of one circle 36 is displayed as one circle 37 centered on the positioning point 33 based on GPS position information , the correction by the moving direction sensor 18 shown in FIG. 5 is performed. as too effectiveness, the control unit 12 moves a distance of 1.0 display unit 32 by superposing a circle 3 8 around the positioning point 33 by the GPS position information by multiplying a correction coefficient smaller than This is the indicated mode.

As shown in FIG. 6, the terminal 30 of the tracker system according to the first to third embodiments for carrying out the invention displays a plurality of display modes downloaded from the management device 20. As a result, a person who sees the display unit 32 of the terminal 30 can easily estimate the moving range of the tracker device 10.

Although the tracker device 10 shown in FIGS. 1 and 3 and 5 does not have a display unit, the tracker device 10 is provided with a display unit, and the display unit provided on the tracker device 10 is provided with a display unit on the terminal 30. The display mode shown in FIG. 2 or 4 or 6 displayed in 32 may be displayed.

Since it is assumed that the reliability of accuracy will decrease if you continue to rely on the number of steps, the color and line type of one circle will be changed according to the elapsed time, etc., depending on the elapsed time since the position information was acquired by GPS or BSSID. It may be changed, and characters, icons, etc. may be displayed. Further, the color and line type of one circle may be changed and characters, icons, etc. may be displayed. Further, when displaying one circle based on the number of steps, a character or an icon indicating that the display is based on the number of steps may be displayed, or a numerical value of the number of steps may be displayed.
