Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an example of a configuration of a main part of a GPS position information display system provided with a function of displaying a moving track secret according to the present invention.

In this system, time information transmitted from an orbiting satellite is received by the portable terminals 1 (#A) to 1 (#C), and the received time information is transmitted to the GPS device 2. The GPS device 2 having received the information finds and displays the position information based on the time information from each portable terminal device 1.

In order to enable such a basic operation, each portable terminal 1 is constituted by a portable telephone or an information terminal (PDA or the like), and a GPS antenna for receiving time information transmitted from an orbiting satellite. An ANT 1, a wireless transmitting unit 11 that transmits time information received by the GPS antenna ANT 1 in the form of a radio signal, and a signal processing unit 12 that controls the wireless transmitting unit 11 are provided.

A navigation controller 23 is displayed on the display screen 24 and displays the position data detected by the position detection unit 21 on the map data, a data memory 25 stores movement locus data described later, and various operation keys. Operation unit 26
And

In such a configuration, the GPS device 2
Displays the detected position data on the map data stored in advance, thereby notifying the current position of each portable terminal device 1 and enabling the detected position data to be stored in the data memory 25 as movement trajectory data. ing.

The present invention is characterized in that a function of allowing the user to arbitrarily select and switch the setting of non-display and display of the movement trajectory data for each portable terminal 1 is added. I have. That is, in the present invention, in order to realize such an additional function, the operation unit 26 can set a non-display mode setting and a non-display cancellation mode setting of the movement trajectory data for each mobile terminal device 1. A non-display setting button 26A and a non-display cancel setting button 26B are provided for each portable terminal device 1.

According to such a GPS device 2, for example, when the non-display setting button 26A corresponding to the portable terminal 1 (#A) is operated, the signal processing unit 20 receives the operation, and receives the movement trajectory data. Is set to non-display mode. As a result, the position data of the portable terminal 1 (#A) detected by the position detection unit 21 is sequentially stored in the data memory 25. Then, in this mode, the signal processing unit 20 prohibits the display of the moving trajectory data stored in the data memory 25 on the map data.

On the other hand, when the non-display cancel setting button 26B is operated, the signal processing section 20 receives this and sets the movement locus data to the non-display cancel mode. As a result, every time the position detecting unit 21 detects the position data of the portable terminal 1 (#A), the detected position data is stored in the data memory 25, and the stored moving trajectory data is displayed on the map data. . During the non-display mode, when the non-display release button 26B is operated, the signal processing unit 20

Here, in order to improve the secret function of the GPS device 2 ', it is necessary to input a personal identification number for the operation of the non-display release button 26B, or the movement locus data P' is previously encrypted in the data memory 25. Alternatively, the decryption key may be input together with the operation of the non-display release button 26B. This way,
Only the user who knows the password or the decryption key can display the movement locus data P '.

Here, when the movement trajectory data P 'is stored in the data memory 25, information serving as a search key such as a time, a stored date, a stored time, and a current position at the time of storage is added. In addition, if necessary, an arbitrary moving trajectory data P ′ is searched using these search key information, and the searched moving trajectory data P ′ is displayed in combination with the related map data 24A. It may be. FIG.

By displaying such journal information on the display screen 24 by a user's appropriate operation, there is an advantage that the management becomes easy.

FIG. 6 shows the G used in the system described above.
This shows still another example of the main configuration of the PS device, and is configured to be connected to the above-described communication terminal 3 via a communication network such as the Internet N.
The GPS device 2A ′ has a configuration further including an interface 27 for connecting to the Internet N.

When the GPS device 2A 'is accessed from the communication terminal 3 via the Internet N, the movement trajectory data P' stored in the data memory 25 is transmitted to the communication terminal 3 by the interface 27. Therefore, transmission is performed at predetermined intervals (for example, at intervals of 30 minutes).
Receiving this, the communication terminal 3 can display the received movement trajectory data P ′ on the display by combining it with the related map data 24A.

The GPS device 2A 'is connected to the communication terminal 3
The communication terminal 3 is also provided with a function of transmitting the movement trajectory data P ′ stored in the data memory 25 to the communication terminal 3 when there is a transmission instruction from the communication terminal 3.

For example, when there is an instruction from the communication terminal 3 to transmit the movement trajectory data P ′ to which certain search key information is added, the GPS device 2A ′ receives the instruction and uses the search key information as a search key. The movement trajectory data P ′ in the data memory 25 is searched, and the searched movement trajectory data P ′ is transmitted from the interface 27.

Here, the communication terminal 3 is the GPS device 2
A ′ may be remotely accessed so that the GPS device 2A ′ can be set to either the non-display mode or the display mode, or can be released.
The A 'side has no sense of being monitored, and is optimal for monitoring the movement trajectory of a salesperson or a wandering elderly person.

Further, the data memory 2 of the GPS device 2A '
The movement trajectory data stored in the communication terminal 3 can be remotely accessed from the communication terminal 3 or transmitted from the GPS device 2A 'to the communication terminal 3 so that the communication terminal 3 itself or the printer attached thereto can be used. For example, such a device may be capable of printing out, and such a device is very useful because it enables the integrated operation management of transportation means such as taxis and trucks to be performed with less labor.
