ROM, a RAM for storing work necessary for program execution, and the like.
[0014]
The navigation information providing device 30 includes a data transmitting / receiving unit 31 that transmits / receives information to / from the navigation terminal device 1, a target position information acquiring unit 32 that acquires target position information from the data received by the data transmitting / receiving unit 31, Similarly, the current position information acquisition unit 33 that acquires current position information from the data received by the data transmitting / receiving unit 31, the target position information acquired by the target position information acquisition unit 32, and the current position information acquisition unit 33 If the position information comparison unit 34 for comparing the current position information and the position information comparison unit 34 compare with each other, and the two do not match, the purpose indicated by the target position information from the current position indicated by the current position information The target position guidance information creating unit 35 for creating guidance information for guiding to the position, indicated by the target position information from the current position indicated by the current position information A target extraction unit 36 for extracting a target between the target position, the target position guidance information creation unit 35 and the target extraction unit 36, and the target position guidance information and the target created and extracted by the navigation terminal device 1 The target position guidance information transmitting unit 37 and the like that transmit to
[0015]
The current position detection unit 11 includes, for example, GPS, PHS, PDC, etc. When GPS is used, position information is detected from latitude and longitude information received from GPS satellites, and PHS and PHS are detected. When PDC is used, position information is detected from the position of the communicating base station. Further, by combining these GPS and PHS, etc., it may be possible to detect the current position with higher accuracy, or send information on the current position received by GPS, PHS, PDC, etc. to the center, You may make it receive in a terminal device what calculated the more exact present position.
[0016]
The setting of the position information for the position information setting unit 12 is set using the extraction result of the input unit 18 and the position information extraction unit 17. When the position information extraction unit 17 receives data transmitted from the center or the like by the data transmission / reception unit 10 and determines that the position information is included in the data, the position information extraction unit 17 Extract the contained location information. For example, if the position information inclusion determination unit 16 defines that data starting with <P> among the data transmitted from the server indicates position information, the position information inclusion determination unit 16 determines whether or not the head is <P>. Thus, it can be determined whether or not position information is included. That is, it is defined that latitude information and longitude information such as 35 degrees 50 minutes 48 seconds north latitude and 135 degrees 40 minutes 25 seconds east longitude are transmitted and received in the format "<P> N35.5048, E135.4025". Thus, it is possible to determine whether or not information including position information has been received.
[0017]
Even when the position information is set for the position information setting unit 12 using the input unit 18, the input destination or target communicates with the center, for example, as described above. In addition, by acquiring latitude information and longitude information of the target and storing this information, it is possible to compare with the current position. With respect to the timing for acquiring the latitude information and longitude information of the set position information, the timing information may be compared with the current position or may be set as the position information.
[0018]
When the comparison condition setting unit 14 compares the current position detected by the current position detection unit 11 with the position information set by the position information setting unit 12, the comparison condition setting unit 14 determines a condition for determining the degree of coincidence. For example, when the distance approaches 4km, or when the number of digits and how many digits are matched in the latitude and longitude information, both are set to match. To. At this time, if the radius is specified within a range of 4 km, the value of the relationship between the location information set by the location information setting unit 12 and the specified radius of 4 km can be calculated using latitude and longitude information. It can be set by requesting.
[0019]
The operation of each unit will be described with reference to the flowchart of FIG.
In FIG. 2, first, target position information is set (step 1). This setting may be input from the input unit 18 as described above, or may be set by inputting the data extracted by the position information extraction unit 17 from the data received by the data transmission / reception unit 10. . The set position information is converted into longitude information and latitude information and stored. The conversion of the longitude and latitude information is performed by communicating with the center regarding the data input from the input unit and receiving the latitude and longitude information regarding the input data.
[0020]
The proximity determination distance indicating how far the position information set in step 1 is to be notified is input (step 2). As described above, the proximity determination distance may be input as a numerical value of a length such as km, or may be input so as to determine that the proximity information is obtained if the latitude information and the longitude information match. Good.
The current position is detected by the current position detector (step 3). The method for detecting the current position is also as described above.
[0021]
It is determined whether or not the position information set in step 1 and the current position information detected in step 3 have approached within the proximity determination distance set in step 2 (step 4).
As a result of the determination in step 4, if it is determined that they are not close, the process returns to step 3 to detect the current position. That is, step 3 and step 4 are repeated until the target position is approached. Of course, the current position detection step of step 3 may be performed every specific period, or the current position may be detected when the user operates.
[0022]
As a result of the determination in step 4, if it is determined that the vehicle is close, the fact that the vehicle is close to the destination is transmitted to the center (step 5). Instead of transmitting to this center, it is also possible to use a terminal device whose destination is set in advance. In addition, what is transmitted to the center or a terminal device set in advance in step 5 may be in the form of a mail to a destination or the like whose destination is determined in advance. Here, in the case of transmitting a mail, a mail to be transmitted in advance is created by the mail creating unit 19. When mail is transmitted, there is an advantage that the contents to be transmitted and the destination can be changed in various ways.
[0023]
If the center with which the navigation terminal device 1 communicates in step 5 has a function of transmitting guidance information, target information, etc. as described later, the center side has a terminal device. Since it is possible to know where the person has approached and how far, the next target, target position information, and the like are transmitted to the terminal side according to the result.
[0024]
The navigation terminal device 1 side receives the transmitted guidance information (step 6), determines whether or not the position information is included therein (step 7), and the position information is included in step 7. If not, the process is terminated and, for example, received information is displayed.
If it is determined in step 7 that position information is included, position information is extracted from the received data (step 8), and the extracted position information is returned to step 1 and set as the next target position information. .
[0025]
As described above, for example, even if the person who has the navigation terminal device 1 does not know the final destination in detail, the center side transmits the target on the way to the navigation terminal device 1, and the navigation terminal device 1 By continuing to communicate with the center and receiving the next target when approaching the target on the side, the final destination can be reached without any problems. Moreover, since it is possible to grasp whether or not the navigation terminal device 1 has stopped by sending a destination that the center wants to stop to a person who has the navigation terminal device 1, It is also possible to grasp the behavior of the person carrying the navigation terminal device 1.
[0026]
Next, a center location information providing apparatus that communicates with the navigation terminal apparatus 1 as described above will be described. The navigation information providing apparatus 30 in FIG. 1 corresponds to this center. The operation of each part of the information providing apparatus 30 will be described with reference to the flowchart of FIG.
[0027]
First, target position information is acquired from the navigation terminal device 1 (step 20). Next, the current position information of the navigation terminal device 1 is acquired (step 21). The target position information acquired in step 20 is compared with the current position information acquired in step 21 (step 22). As a result of the comparison in step 22, if they match, the process ends. If they do not match, the distance and direction from the current position indicated by the current position information acquired at step 21 to the target position indicated by the target position information acquired at step 20 are calculated (step 23). Based on the distance and direction extracted in step 23, if there is a target in the middle of the current position and the target position, the target is extracted (step 24). This target extraction may be performed by searching whether there is a target between the current information and the target information in a database in the information providing apparatus side or another information providing apparatus and using the result.
[0028]
The target information extracted in the above step and guidance information such as the direction and distance from the current position to the destination determined in the above step 23 are transmitted to the navigation terminal device 1 side (step 25). When this target object information (position information where the target object exists) is transmitted, it can be understood that the vehicle has approached the target object by receiving information from the navigation terminal apparatus 1 such as proximity to the transmitted target object. Therefore, the information on the other target or the final destination can be transmitted from the target next.
[0029]
【The invention's effect】
As is apparent from the configuration described above, according to the first aspect of the present invention, the position information comparison for comparing the current position information detected by the current position information detecting means with the position information set by the target position information setting means. And a communication control means for transmitting the position information to the center and receiving information returned from the center when the position information comparing means determines that the position information matches, and information returned from the center. Position information extracting means for extracting the position information included in the target position information setting means, the position information extracted by the position information extraction means is set as a new target position, Even if the current position and the target position match, if position information such as a destination or a target is received from the center side, the received position information is used as a new target position. Used as broadcast, it is possible to effectively induce terminal device for the intended purpose position.
[0030]
According to the second aspect of the present invention, since the position information coincidence determining means can know that it has approached the destination even when it approaches within a certain distance, it approaches the destination within a predetermined distance. If it is possible to communicate with the center in the event that the destination is close to the destination, it is easier to instruct and communicate what to do next. In addition, it is possible to more easily grasp the behavior of a person who possesses the position information transmitting / receiving terminal device.
[0032]
In addition, according to the invention of claim 3 , since the mail transmitting means for transmitting mail is further added when the destination and the current position are close to or coincide with each other, not only the specific center but also the user intends. A person who has been designated in advance can easily be contacted, and even if the person is absent, it is possible to easily leave a record and a history of going to the vicinity of the target point.
