Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method and system for providing location information.
[0002]
[Prior art]
Portable information processing terminals such as mobile phones and PDAs have become widespread. These mobile terminals are equipped with a system for positioning their own current position by supplementing radio waves from satellites such as GPS, or by acquiring their own current position from position information of a base station. By obtaining the position information of the user, the position information of the user holding the mobile terminal can be obtained.
[0003]
[Problems to be solved by the invention]
With the spread of such mobile terminals, search service systems that provide their own current location are being studied. As one of them, the use of location information as part of the service of the delivery system is being studied. For example, Japanese Patent Application Laid-Open No. 9-35192 discloses a delivery navigation device using a GPS positioning device. This navigation device is located by means for positioning the current position of a delivery vehicle by GPS, means for storing information such as a delivery destination location and a telephone number, means for displaying a map of a delivery area, and means for positioning. When the distance between the current location and the stored delivery destination or the estimated arrival time is less than a certain value, a means is provided for making a telephone call to the delivery destination to confirm that the user is at home, and a notifying means for notifying the driver of the confirmation result. Therefore, when the delivery company's car approaches the delivery destination within a certain distance, it is possible to inform the estimated delivery time and to confirm whether or not the user is at home.
[0004]
However, in this method, only the arrival time is notified to the recipient for the convenience of the recipient, and the recipient cannot always confirm the delivery status. When the delivery company's car approaches the delivery destination within a certain distance, the recipient cannot check the delivery status if it is absent. In addition, in the case of absence, even if the purport of the delivery is input to the answering machine, the recipient does not always hear it. For example, if the recording tape has expired, the message is wasted. Furthermore, the timing of making a telephone call to confirm whether the user is at home or absent is a problem, and there is a problem if it is too early or too late, and the sense of that time differs depending on the user. Therefore, it is impossible to set the timing uniformly.
[0005]
There is also a way to give the recipient the freedom to check the location of the package. With this method, the location information of the package is open to the recipient, so you can always check it freely and stay at home when it is delivered, or leave it at home when it is delivered. If you can't be there, you have the option to adjust the delivery time beforehand, go get it or the recipient has the option to be delivered.
[0006]
Furthermore, if the sender can be given the freedom to confirm the position of the package, it is possible to confirm whether the sender has freely arrived at the package and at what time the package will arrive.
[0007]
However, if the recipient and / or the sender have the freedom to locate the package, it is not possible to specify how often and how often the recipient or the sender performs the location confirmation. Mobile terminals that are bundled with or attached to luggage must be battery-powered, so they do not have infinite power. Frequent position confirmation consumes power for GPS positioning, so the battery may be consumed before the package reaches the key recipient. You can make the battery bigger, but think that it will affect the delivery cost unless it is a small enough to be bundled with each package or attached to the baggage, and if it is almost a disposable mobile terminal And the capacity of the battery needs to be minimized.
[0008]
On the other hand, if the portable terminal of the package is turned on for the first time near the recipient and the location information is obtained and the arrival time is known, it is impossible to adjust the schedule or the delivery method in advance. is there. Also, if the movement of the luggage on the way is not known at all, it cannot be said that the quality of the delivery confirmation service is high. Further, if the timing of receiving the position information is not freely set by the recipient, the disadvantages of not being able to freely adjust the delivery schedule or of wasting time waiting at home are not eliminated.
[0009]
A method is also conceivable in which the place where the package is located is periodically notified to the recipient or the sender by e-mail or the like. However, it is not known how the baggage has moved since the date and time when the mail was sent. Therefore, when compared with a system that allows the recipient or sender to freely check the location of the package, the information that the recipient or sender can obtain is limited, and the sender can check the location of the package at any time, People can adjust the schedule in advance or shorten the waiting time, reducing the degree of freedom to use the time effectively.
[0010]
Therefore, in the present invention, the recipient and / or the sender can freely check the position of the package at any time, and furthermore, the location information can be securely obtained until the user arrives at the destination by using a mobile terminal having a small-capacity battery. It is an object of the present invention to provide a method and a system for providing position information that can be provided to a user.
[0011]
[Means for Solving the Problems]
Therefore, in the position information providing system of the present invention, a parent terminal serving as a mobile base station is mounted on transportation means such as a truck, a train, a ship, and an airplane, and identification information of the child terminal attached to the luggage is provided together with the position information of the parent terminal. To be offered. That is, the position information providing system of the present invention is a mobile child terminal provided with child identification information output means for outputting its own identification information, and a mobile parent terminal, the position indicating the current location of the parent terminal. Position information acquiring means for acquiring information, child terminal identifying means for acquiring identification information of a child terminal moving with the parent terminal, and outputting the acquired identification information of the child terminal and the positional information of the parent terminal in association with each other And a parent terminal provided with position information output means. In this position information providing system, the mobile child terminal outputs its own identification information (child identification information output step), and the mobile parent terminal acquires position information indicating the current location of the parent terminal (position Information acquisition step), the parent terminal acquires the identification information of the child terminal that moves with the parent terminal (child terminal identification step), and the parent terminal associates the acquired identification information of the child terminal with the position information and Output (position information output step). Therefore, the child terminal can provide the current position of the child terminal to an external search system or the like only by providing the identification information of the child terminal to the parent terminal by an appropriate means. Therefore, the child terminal does not need a means for acquiring position information, and has a very small battery and operates for a long time. In addition, since the parent terminal can receive power supply from the transportation means, it is easy to acquire highly accurate position information by GPS positioning or the like. Therefore, according to the position information providing system of the present invention, it is possible to provide high-accuracy position information using a child terminal having a simple configuration.
[0012]
In order to determine the child terminal that moves with the parent terminal, it is rather preferable that the child identification information output means of the child terminal transmit the identification information by radio with an output that can be received only by the nearby parent terminal. Power consumption may be small. Examples of such child identification information output means include low-output wireless, Bluetooth, and wireless LAN.
[0013]
Instead of the parent terminal associating and outputting the identification information of the child terminal and the position information of the parent terminal, the parent terminal associates and outputs the acquired identification information of the child terminal and the identification information of the parent terminal. Means or steps may be provided, and the position information may be output in association with the identification information of the parent terminal.
[0014]
In any case, the child terminal is a terminal that moves with the luggage, and the parent terminal is mounted on the transportation means, whereby a system that can search the position of the luggage for a long time can be constructed. For example, in such a system that provides location information of a package, the child terminal is provided as a compact electronic tag. It is also possible to provide a search service device for providing the location information of the package by associating the identification information of the package with the identification information of the child terminal, and to provide an interface between the searcher and the parent terminal.
[0015]
The position information of the child terminal of the present invention is provided as the position information of the parent terminal that moves with the child terminal. Therefore, when the parent terminal to which the child terminal belongs changes, it is necessary to update the position information of the child terminal or update the relationship between the parent terminal and the child terminal. Therefore, the parent terminal outputs its own identification information, and the child terminal is capable of acquiring the identification information of the parent terminal, and is provided with storage means for storing the acquired identification information of the parent terminal. If the identification information is different from the identification information of the previous parent terminal stored in the storage means, the identification information of the parent terminal in the storage means is updated, and the parent terminal associates the new position information with the identification information of the child terminal. Or a new relationship between the parent terminal and the child terminal. When the parent terminal has a parent identification information output unit that outputs its own identification information, the range of the child terminal that moves together with the parent terminal can be set by limiting the communicable range.
[0016]
Such a child terminal constituting the position information providing system of the present invention includes an identification information output unit that outputs its own identification information, another terminal identification unit that acquires the identification information of another terminal, and another acquired terminal. The storage means for storing the identification information of the terminal, and when the obtained identification information of the other terminal is different from the identification information of the other terminal of the storage means, the identification information of the other terminal of the storage means is updated and another The mobile terminal includes an updating unit that outputs the position information and the identification information of the terminal in association with each other. Alternatively, an identification information output unit that outputs its own identification information, another terminal identification unit that acquires the identification information of another terminal that can provide position information, and a storage unit that stores the acquired identification information of the other terminal If the obtained identification information of the other terminal is different from the identification information of the other terminal of the storage unit, the identification information of the other terminal of the storage unit is updated, and the identification information of the terminal is output from the other terminal. And updating means for causing the terminal to update. With this device, you only need to keep your device in your baggage, and when another device with which this device can communicate changes, the device's identification information will be sent automatically. Can be traced. Therefore, although it is effective to use a fixed base station as another terminal, a system using a mobile base station can detect its position information with high accuracy even while moving.
[0017]
In the mobile terminal, the step of outputting its own identification information, the step of acquiring the identification information of another terminal, the acquired identification information of the other terminal, and the previously acquired identification information of the other terminal are performed. If not, the step of updating the identification information of the other terminal and causing the other terminal to output the position information and the identification information of the terminal in association with each other is executed. When the position information is provided from another terminal as needed, the identification information of the terminal may be output from the other terminal and the association between the other terminal and the terminal may be registered. For this purpose, a program or a program product for a mobile terminal having instructions capable of executing the processes of these steps can be provided via an appropriate recording medium or network.
[0018]
Further, the parent terminal constituting the position information providing system of the present invention includes: a position information acquisition unit that acquires position information indicating a current position; a terminal identification unit that acquires identification information of another terminal that moves together; This is a terminal having position information output means for outputting identification information of another terminal and position information in association with each other. A terminal having associated information output means for outputting the associated identification information of the other terminal and the identification information of the own terminal in association with each other, and a position information output means for outputting the identification information of the own terminal in association with the position information. There may be. When the other terminal changes, an identification information output means for outputting its own identification information is provided to output the relationship with the other terminal, and upon request from the other terminal, the identification information and the position information of the other terminal are provided. Is preferably output in association with other terminals, or the relationship with other terminals is output.
[0019]
Therefore, at the parent terminal, a step of acquiring position information indicating the current location, a step of acquiring identification information of another terminal that moves together, and outputting the acquired identification information and position information of the other terminal in association with each other Is performed. Alternatively, the related information output step of associating the obtained identification information of the other terminal with its own identification information and outputting the information and the position information output step of outputting the identification information of itself and the position information in association with each other are executed. Is done. A program or a program product for a mobile terminal having instructions capable of executing the processes of those steps can be provided via an appropriate recording medium or a network.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an outline of a position information providing system 1 in delivery of a package. In this example, the sender (sender) 91 of the package 99 entrusts delivery to a delivery company 92, and the driver 93 of the delivery company 92 delivers the package 99 to the delivery destination 95 by the truck 94. The search system 30 (search service device) provides positional information on the current location of the package 99 to the recipient 95 and the sender 91 via a public telephone network or the Internet, so that the status of the delivery process of the package 99 can be freely adjusted. A location information providing service (baggage management service) 1 that can be confirmed.
[0021]
In order to provide the location information providing service 1, the business office 97 of the delivery company 92 receives the package 99 from the sender 91 and attaches the electronic tag 80 (child terminal) to the package 99. When the luggage 99 to which the electronic tag 80 is attached is mounted on the truck 94, the luggage 99 communicates with the in-vehicle terminal 70 (parent terminal) of the truck 94 and uses the current location information (position information) φ of the truck 94 as the position information of the luggage 99. The search system 30 is provided. Therefore, a searcher such as the receiver 95, the sender 91, and the delivery company 92 can obtain the position information φ of the package 99 by making an inquiry to the search system 30.
[0022]
FIG. 2 shows a schematic configuration of the electronic tag 80. The electronic tag 80 includes a short-range wireless communication unit 81, a memory 82, a CPU 84 that performs various functions by executing a program 83 recorded in the memory 82, and a battery power supply 85 for driving these. It has. The CPU 84 outputs a self-identification information CID 86 recorded in the memory 82 via the wireless communication means 81 to the CID output unit 87, a PID acquisition unit 88 to acquire the identification information PID 76 of the vehicle-mounted terminal 70, and a PDI 76 Is different from the PID 76 stored in the memory 82, the PID of the memory 82 is updated, and the update unit 89 that requests the in-vehicle terminal 70 to output to the search system 30 via the wireless communication unit 81 Perform the function.
[0023]
FIG. 3 shows a schematic configuration of the vehicle-mounted terminal 70. The in-vehicle terminal 70 includes a first wireless communication unit 71 that can wirelessly communicate with the electronic tag 80, a second wireless communication unit 72 that can communicate with the search system 30 via a mobile phone network or a PHS network, and the like. A GPS unit 73 that receives radio waves from the satellite 5 to obtain high-precision position information φ; a display unit 74 such as an LCD that provides information to a driver 93; a memory 75; a CPU 78; And a power supply circuit 77 for performing the operation. The CPU 78 performs various functions by executing the program 79. In this example, the CPU 78 outputs its own identification information PID76 to the track 94 by the first communication means 71 and the PID output section 61 for outputting the identification information PID76 to the track 94 by the first communication means 71. The CID acquisition unit 62 for acquiring the CID 86 of the electronic tag 80 attached to the loaded luggage 99, the position acquisition unit 63 for acquiring the current position information (position information) φ by the GPS unit 73, and the acquired CID 86 A related information output unit 64 that transmits the search information 30 to the search system 30 by the second communication unit 72 in association with the PID 76 of the own device, and a position information output unit that transmits the position information φ of the own device to the search system 30 by the second communication unit 72 The function as 65 is performed.
[0024]
As described above, in the position information providing system 1 of the present example, the identification information CID 86 of the electronic tag 80 of the luggage 99 mounted on the truck 94 is associated with the position information φ from the in-vehicle terminal 70 of the truck 94. Alternatively, it is sent to the search system 30 in a state where it can be associated. Therefore, the searcher can obtain detailed position information of the package 99 by inquiring of the search system 30 about the position of the package 99. In the position information providing system 1, it is the in-vehicle terminal 70 that performs GPS positioning and provides the position information to the search system 30, and the electronic tag 80 provides a CID 86 for identifying the package and transmits the position information. It will only act as a trigger. Therefore, it is the in-vehicle terminal 70 that consumes most of the power required to provide the position information of the luggage 99, and the electronic tag 80 is a mobile terminal with low power consumption and a simple configuration. For this reason, since the electronic tag 80 continues to function for a long time during transportation, the searcher can freely acquire the position information of the package 99 at any time. Further, since the electronic tag 80 has an extremely simple configuration, it is low-cost and compact, and can be disposable.
[0025]
FIG. 4 shows a schematic configuration of a search system 30 functioning as a search center. The search system 30 is constituted by a server or a server system opened on the Internet, and a communication means 31 capable of communicating with the in-vehicle terminal 70 by an appropriate method, for example, a mobile phone, a PHS, or the like; Information retrieval means 32 for acquiring the CID 86 of the electronic tag 80 and the positional information φ of the on-board terminal 70, and a terminal / package for managing the CID 86 of the electronic tag 80 in association with the identification information and the delivery information of the package 99. The system includes a management unit 33, a database 34 in which information on terminals and packages is recorded, and a response unit 35 that receives an inquiry from a searcher via the Internet or the like and returns a response including position information φ.
[0026]
FIG. 5 shows an example of data registered in the database 34. In the file 39, the identification information CID 86 of the electronic tag 80 is recorded in direct association with the position information φ. Since the CID 86 of the electronic tag is associated with the slip number 21 of the luggage 99, the searcher can obtain the position information φ of the luggage by querying the slip number 21. The files 38 and 37 are examples in which the CID 86 of the electronic tag 80 is indirectly associated with the position information φ. The file 37 records the identification information PID 76, the position information φ, and the time T of the in-vehicle terminal 70, and the file 38 records the CID 86 of the electronic tag 80, the PID 76 of the in-vehicle terminal 70, and the time T. Therefore, if the slip number 21 and the time T of the luggage 99 are known, the PID 76 of the in-vehicle terminal 70 on which the electronic tag 80 is mounted is known at that time, and the position information φ of the luggage 99 is obtained from the position information φ of the in-vehicle terminal 70. Prove.
[0027]
FIG. 6 is a flowchart illustrating the operation of the electronic tag 80 and the in-vehicle terminal 70. In the in-vehicle terminal 70, when the predetermined measurement timing is reached in step 111, the position acquisition unit 63 acquires the position information φ by the GPS unit 73 in step 112. Then, in step 113, the PID output unit 61 outputs the PID 76 by the first wireless communication unit 71. On the other hand, in the electronic tag 80, at the detection timing 101, the wireless communication unit 81 detects whether or not the PID 76 is being broadcast, and determines whether or not the parent terminal, that is, the in-vehicle terminal 70 is in the vicinity. In this process, the in-vehicle terminal 70 needs to detect only the electronic tag 80 of the luggage 99 mounted on the truck 94. Therefore, the communicable distance between the first wireless communication unit 71 of the in-vehicle terminal 70 that outputs the PID and the wireless communication unit 81 of the electronic tag 80 that acquires the PID is limited to within the range of the truck 94. It is desirable. For example, low-power wireless communication, optical communication with a limited reach, or a short-distance network system such as Bluetooth are suitable communication means.
[0028]
In the electronic tag 80, the PID 76 is acquired by the PID acquisition unit 88 in step 103, and when the PID 76 is different from the previous PID 76 stored in the memory 82, the PID 76 in the memory 82 is updated by the update unit 89 in step 104. , CID output section 87 outputs own CID 86. In the vehicle-mounted terminal 70, the CID acquisition unit 62 acquires the output CID 86, and registers the CID 86 in the memory 75 in step 115. Further, the CID 86 and the position information φ registered in step 116 are output from the position information output unit 65 to the search system 30 using the second wireless communication unit 72. Further, even when the CID 86 cannot be acquired in step 114, if the timing to output the position information φ is reached in step 117, the CID 86 and the position information φ at that time are output in step 116. Therefore, a file 39 in which the CID 86 and the position information φ are associated is created in the search system 30. Therefore, the electronic tag 80 and the position information φ can be searched at any time by the slip number 21. When the in-vehicle terminal 70 associates the CID 86 with the position information φ and provides it to the search system 30, the CID 86 registered in the memory 75 of the in-vehicle terminal 70 is referred to the electronic tag 80 at an appropriate timing, and the response is returned. Must be sequentially deleted.
[0029]
FIG. 7 is a flowchart illustrating the operation of the in-vehicle terminal 70 when the CID 86 and the position information φ are associated on the search system 30 side. At the timing of measurement in step 111, the position information φ is acquired by the position acquisition unit 63 in step 112. Then, in step 121, the PID 76 of the in-vehicle terminal 70 and the position information φ are output to the search system 30 by the position information output unit 65. Thereby, a file 37 in which the position information φ and the PID 76 of the vehicle body terminal 70 are associated is created in the search system 30. Further, the in-vehicle terminal 70 outputs the PID 76 by the PID output unit 61 in step 113. Since the electronic tag 80 outputs its own CID 86 when the PID 76 is new, the electronic tag 80 acquires the CID 86 by the CID acquisition unit 62 in step 114, and outputs the CID 86 to the search system 30 by the related information output unit 64 in step 122. In the search system 30, a file 38 in which the PID 76 and the CID 86 are associated is generated. Therefore, when the searcher makes an inquiry with the slip number 21, the position information φ of the package 99 can be returned to the searcher by tracing the PID 76 from the CID 86 and further tracing the position information φ from the PID 76.
[0030]
FIG. 8 shows a case where the search system (center) 30 obtains the latest position information φ of the package 99 in response to a request from a searcher, for example, a recipient 95. Although FIGS. 6 and 7 show a system in which location information is periodically accumulated in the search system 30, this figure shows a system that acquires location information only when requested by a searcher. ing. The only difference between the operations of these systems is whether the trigger for performing GPS positioning in the in-vehicle terminal 70 is a periodic timing or a request from the search system 30. When the luggage 99 is received in step 130, the electronic tag 80 is attached to the luggage 99 at the business office 97. Then, in step 131, the ID (CID) of the electronic tag 80 and the ID (slip number) 21 attached to the package at the business office are registered in the database 34 of the center (search system) 30. Thus, the searcher 95 can search for the position information of the electronic tag 80 by the slip number 21.
[0031]
When the luggage 99 is loaded on the delivery vehicle 94 in step 132, the CID 86 is output from the electronic tag 80, the in-vehicle terminal 70 receives the CID 86, sends the CID 86 and the PID 76 to the search system 30, and registers in step 133. As a result, the electronic tag 80 and the in-vehicle terminal 70 are associated with each other, and thereafter, the position information φ of the in-vehicle terminal 70 is treated as the position information of the electronic tag 80 unless the in-vehicle terminal 70 changes. When there is a search request from the searcher 95, the search system 30 checks the PID 76 of the corresponding vehicle-mounted terminal 70 in step 135, and requests the corresponding vehicle-mounted terminal 70 to acquire position information in step 136. Therefore, a GPS positioning request is issued to the in-vehicle terminal 70, the in-vehicle terminal 70 performs GPS positioning, and returns the position information φ to the search system 30. Thereby, the response means 35 of the search system returns a response including the position information φ corresponding to the package 99 to the searcher 95.
[0032]
As described above, the position information providing system 1 in which the electronic tag 80 is a child terminal and the in-vehicle terminal 70 is a parent terminal, consumes almost no power in the electronic tag 80 and sends the luggage 99 to the search system 30 or the searcher. Detailed location information can be provided at any time. Therefore, the searcher can always know the position of the luggage 99 at a pinpoint. On the other hand, the electronic tag 80 attached to the luggage 99 does not require a function for long-distance communication such as a mobile phone or PHS, and does not require a function for acquiring position information such as a GPS unit. Therefore, the electronic tag 80 is small, lightweight, and low-cost. Further, even a tag having such a simple structure consumes very little power and therefore has a long life, and performs a function of providing positional information of the luggage 99 even for long-term transportation.
[0033]
Note that, in the above example, an example in which luggage is mounted on a truck is shown, but the transportation means is not limited to a truck, and the present invention can be applied to various transportation methods such as railroads, airplanes, ships, and the like. . Also, when transporting a package using an organization having different modes of transportation, it is possible to always obtain positional information of the package from all the transportation means simply by attaching one electronic tag to the package.
[0034]
Further, the position information is not limited to the position information obtained by the GPS positioning, and it is also possible to use the position information of the base station used for the communication between the in-vehicle terminal and the search system. However, since the in-vehicle terminal is not so limited in power and not so limited in weight, there is no problem in mounting a function for acquiring highly accurate position information such as GPS. Further, it is also possible to provide the in-vehicle terminal with a function of acquiring two or more pieces of position information of the GPS position information and the base station position information and improving the reliability of the position information.
[0035]
【The invention's effect】
As described above, in the present invention, the mobile second terminal capable of acquiring its own position information is used as a base station, and the position of the first terminal such as an electronic tag that moves with the second terminal is used. The information is output from the second terminal. Therefore, the first terminal that moves with the luggage can be simple and have a long life. On the other hand, since the searcher can obtain detailed location information of the package at any time from the second terminal, the recipient can know the detailed date and time of arrival of the package and the schedule can be easily adjusted. In addition, the sender can freely check the delivery status of the package and whether or not the package has arrived. The searcher can benefit from using the location information providing system of the present invention, such as the delivery person can improve the delivery efficiency because the delivery person can increase the home ratio of the recipient.
