Description

  The present invention relates to a package-attached electronic tag, a package management system, and a package management method.

2. Description of the Related Art Conventionally, a bar code, which is a machine-readable code, is printed and used on a medium such as paper attached to a package in order to manage the package during transportation.
For example, when an aircraft luggage is to be deposited at an airline company's check-in counter when boarding an aircraft, a baggage tag attached to the baggage may be used as a luggage attachment tag. Then, it is performed to recognize, sort, and ship the bar code of the baggage tag by reading it with a bar code reader.

However, the recognition rate decreases depending on the status when the barcode is read by the barcode reader (reading angle, blurred printing of the baggage tag, wrinkles, tag involvement during transport, etc.), and the person in charge visually or handy each time It is necessary to perform confirmation by reading using a reader, which is a burden.
For this reason, some airlines are adding RFID (radio frequency identifier) to the above-mentioned baggage tag in order to reduce the burden on the person in charge and to improve the tracking management of the baggage itself ( For example, refer to Patent Document 1). And, by replacing the barcode with the RFID, the recognition rate of the identification number of the air cargo is improved, and the addition of the person in charge is reduced.

JP 2001-240218 A

However, the baggage tag of Patent Document 1 described above is simply a UHF (ultra high frequency) -TID (tag identifier), an EPC (electronic product code), or a tag IC, which is written in an RFID integrated IC (tag IC). Reading out the specific information in the user memory area in is an alternative to reading the bar code.
That is, it is intended to be used as a package of an airplane to be loaded by a belt conveyor, and it is not intended to correspond to the convenience of the user but to reduce the burden on the person in charge of checking in or loading the package. And

For this reason, if the baggage is stolen at the airport, or if the baggage is not loaded on the aircraft on which the user is boarded and the lost baggage is generated despite the check-in, the baggage tag is located at the position of the baggage. It can not respond to detection.
Although it is sufficient to add a GPS (global positioning system) function to the tag IC, since the power consumption is large, in order to drive the GPS related function (or the GPS related IC provided independently to the tag) in the tag IC In addition, a predetermined battery capacity is required.
In addition, when transmitting own position information, since the position information is always transmitted to the management server using WiFi or 3G (generation) / LTE (long term evolution), there are many communication costs.

In addition, data communication using the UHF band has been maintained as a communication infrastructure for industrial use, such as identification of luggage transported to a belt conveyor. On the other hand, Bluetooth (registered trademark) and BLE (bluetooth low energy) (registered trademark) that can be used by portable terminals such as smartphones used by users and the data communication in the UHF band have no affinity on the communication standard. For example, when trying to write the user's identification information and the information of the airplane to be boarded into the IC tag attached to the above-mentioned baggage tag, the smartphone generally uses Bluetooth (registered trademark) communication, but the UHF band data communication standard Because you can not handle it, you can not do it directly.

The RFID module unit 131 performs data transmission between the package-attached electronic tag 13 and the reader / writer using radio waves in the HF band (short wave band 13.56 MHz) or the UHF band (ultra high frequency band 860 MHz to 960 MHz). . For example, in the case of a baggage mounted on an aircraft, the reader / writer reads identification information held inside the functional package-attached electronic tag 13 on a belt conveyor or by a reader / writer in a handy terminal owned by an employee. Is done.

  The BLE module unit 132 receives the advertisement packet output from the beacon terminal using the BLE wireless technology disposed in a predetermined space, and receives the radio wave intensity of the radio wave propagating the advertisement packet ( RSSI: Received signal strength indicator). Each of the advertisement packets includes terminal identification information for identifying each of the transmitted beacon terminals.

The base station identification information is information for identifying each of the LPWA base stations. The position information indicates, for example, a place name of a position where the LPWA base station is indicated, which is indicated by the base station identification information.

Next, processing of position detection by the package management system according to the embodiment of the present invention will be described with reference to FIGS. 2, 6 and 7. FIG. 6 is a flowchart showing an operation example of position detection processing by the package management system according to the embodiment of the present invention. FIG. 7 is a conceptual diagram for explaining a processing example of position detection by the package management system.
In FIG. 7, each of beacon terminals 31 has a predetermined distance and is arranged at an airport facility (departure / arrival lobby, store area, etc.) 300. The beacon terminal 31 periodically outputs an advertisement packet including terminal identification information for identifying itself and presence / absence of boundary end information with a predetermined output strength. The airport facility 300 is an example of a detection space where position detection can be performed by the beacon terminal.

  Here, the boundary end information is information indicating that the boundary end information is provided at the end of the airport facility 300 near the exit 300E or the check-in counter. The exit 300E indicates an exit from the space of the airport facility 300. For example, in addition to the actual exit, a check-in counter or the like that the user gives up by depositing luggage is indicated. That is, the exit 300E shows the exit from the airport facility 300 under the environment of position detection by the baggage attached electronic tag 13 added to the user's baggage by the beacon terminal 31.

In each of the regions 350, 351 and 352 adjacent to the airport facility 300, LPWA base stations 350B, 351B and 352B are provided respectively. Each of LPWA base stations 350B, 351B and 352B periodically outputs an LPWA packet including base station identification information for identifying itself with a predetermined output power.
Each of the areas 701 and 702 indicates the use area at a place different from the place where the airport facility 300 is present. For example, the airport facility 300 is located at Narita Airport in Japan, the area 701 is an area where Heathrow Airport of England is located, and the area 702 is an area where Charles De Gaulle Airport of France is located.

Step S101:
The user activates the luggage attached electronic tag 13 attached to the baggage by the portable terminal to put it into operation. In addition, when attached to a bag, it may be activated to be in an operating state.
Here, tag identification information, which is identification information for identifying the tag itself, is written and stored in the position information database 12 in advance (registered). That is, in the position information database 12, a log table in which the tag identification information of the package-attached electronic tag 13 is associated with the inquiry destination information used when making an inquiry to the SIM is written and stored in advance. There is. The detailed information of the baggage may be stored in a database or the like on the cloud side, and confirmation may be made each time it is necessary. For this reason, in the position information database 12, minimum correspondence relationships such as tag identification information and the inquiry destination information may be stored.

Step S102:
The BLE module unit 132 receives an advertisement packet output from each of the beacon terminals 31.
Then, the BLE module unit 132 outputs, to the first position detection unit 137, the reception signal of each of the advertisement packets output from each of the beacon terminals 31.
The first position detection unit 137 selects three advertisement packets in the received signal of the advertisement packet output from each of the beacon terminals 31 from the one with the highest radio wave strength. Then, the first position detection unit 137 controls the signal strength of the radio wave strength of the selected advertisement packet, the terminal identification information of the beacon terminal 31 which has transmitted the advertisement packet, and the presence or absence of the boundary end information. Output to

Step S103:
The control unit 135 determines whether any one of the advertisement packets supplied from the BLE module unit 132 includes boundary end information.
At this time, when any of the advertisement packets contains boundary end information, the control unit 135 advances the process to step 104. On the other hand, when none of the advertisement packets contains boundary end information, the control unit 135 advances the process to step 105.

Step S104:
In the control unit 135, in three of the field strengths of the advertisement packet supplied from the BLE module section 132, the field strength of one of the received signals of the advertisement packet not including the boundary end information is a first threshold (20 dBm ) Or not.
At this time, if the radio wave strength of any of the received signals of the advertisement packet not including the boundary end information is less than the first threshold, the control unit 135 indicates that the baggage attached with the baggage attached electronic tag 13 is the airport facility 300. If it is estimated that the vehicle is in the state of leaving, the process proceeds to step S108. That is, when the strength of the reception signal supplied from the BLE (Bluetooth Low Energy) (registered trademark) module unit 132 becomes less than the first threshold, the baggage attached electronic outside the communication area with the beacon terminal 31 in the nearest vicinity It is estimated that the tag 13 moves.
On the other hand, when the radio wave strength of any of the received signals of the advertisement packet not including the boundary end information is equal to or greater than the first threshold, the control unit 135 determines that the baggage attached with the luggage attached electronic tag 13 is the airport facility 300. If it is estimated that it is not in the state of coming out, the process proceeds to step S105.

Step S105:
For the position log table in the storage unit 136, the control unit 135 uses time information that is a time stamp, the field strength of the three advertisement packets supplied from the first position detection unit 137, and the advertisement The terminal identification information of the beacon terminal 31 that has transmitted the packet and the detection unit identification information for identifying the first position detection unit 137 are combined, written and stored.

Step S106:
The control unit 135 detects whether the mobile communication module unit 134 receives an inquiry about location information from the package tag management server 11 via 3G / LTE.
At this time, when the control unit 135 detects that the mobile communication module unit 134 has received an inquiry about position information, the control unit 135 advances the process to step S107. On the other hand, when the control unit 135 does not detect that the mobile communication module unit 134 has received an inquiry about position information, the control unit 135 advances the process to step S103.

Step S107:
The control unit 135 reads out from the log table of the storage unit 136 the detection unit identification information and the position information in each time information together with the tag identification information of the package-attached electronic tag 13. Then, the control unit 135 transmits the read time information, detection unit identification information and position information to the package tag management server 11 via the mobile communication module unit 134 and 3G / LTE.
Further, the package tag management server 11 determines that the position information detected by the first position detection unit 137 is based on the detection unit identification information, refers to the beacon terminal table in the position information database 12, and identifies the terminal in the position information. The spatial position information of the beacon terminal 31 indicated by the information is extracted.

Then, the package tag management server 11 uses the three-point positioning method based on the extracted spatial position information of the beacon terminal 31 and the radio field strength of the received signal of the advertisement packet of each beacon terminal 31 to obtain each time The coordinate value in the airport facility 300 of the luggage attached electronic tag 13 of information is calculated. The package tag management server 11 displays the coordinate value of each piece of time information, and notifies the movement locus of the package-attached electronic tag 13 in the airport facility 300 by displaying it on the display screen. For example, when the baggage is stolen in the airport facility 300, the person in charge performs the above-mentioned operation in the luggage tag management server 11 according to an inquiry from the user to confirm the movement locus of the baggage, and the position of the baggage Can be notified to the user.
In addition, when notifying the user of the position of the baggage, gray scale or different color according to the distance to the boundary end depending on the radio wave intensity of the beacon terminal 31 located at the boundary end. It is also possible to display how much distance is provided at the boundary end.

Step S108:
The LPWA module unit 133 starts to receive the LPWA packet output from each of the LPWA base stations 350B, 351B and 352B.
Then, the LPWA module unit 133 outputs, to the second position detection unit 138, the reception signal of each of the LPWA packets output from each of the LPWA base stations 350B, 351B, and 352B.

Step S109:
The second position detection unit 138 selects the LPWA packet with the highest radio wave strength in the received signal of the LPWA packet output from each of the LPWA base stations 350B, 351B, and 352B. Then, the second position detection unit 138 determines whether the highest radio wave intensity is equal to or higher than the second threshold, that is, determines whether or not the voltage level can be detected.
At this time, if the highest radio wave intensity is equal to or higher than the second threshold, the second position detection unit 138 proceeds to step S110, assuming that position detection is possible. On the other hand, when the highest radio field intensity is less than the second threshold, the second position detection unit 138 assumes that position detection is not possible, and starts counting and advances the process to step S113.

Step S110:
The control unit 135 causes the position log table in the storage unit 136 to have time information as a time stamp, the radio wave intensity of the LPWA packet with the highest radio wave intensity supplied from the second position detection unit 138, and the LPWA packet. The base station identification information of the transmitted LPWA base station and the detection unit identification information for identifying the second position detection unit 138 are combined, written and stored.

Step S111:
The control unit 135 detects whether the mobile communication module unit 134 has received an inquiry about location information from the package tag management server 11 by the LPWA packet via 3G / LTE.
At this time, when the control unit 135 detects that the mobile communication module unit 134 has received an inquiry about position information, the control unit 135 advances the process to step S112. On the other hand, when the control unit 135 does not detect that the mobile communication module unit 134 has received an inquiry about position information, the control unit 135 advances the process to step S109.

Step S112:
The control unit 135 reads out from the log table of the storage unit 136 the detection unit identification information and the position information in each time information together with the tag identification information of the package-attached electronic tag 13. Then, the control unit 135 transmits the read time information, detection unit identification information, and position information to the package tag management server 11 by the LPWA packet via the mobile communication module unit 134 and 3G / LTE.
When the luggage tag management server 11 determines from the detection unit identification information that the position information is the position information detected by the first position detection unit 137, the package tag management server 11 refers to the beacon terminal table in the position information database 12 and Spatial position information of the beacon terminal 31 indicated by the identification information is extracted. Furthermore, when it is determined that the package tag management server 11 is the position information detected by the second position detection unit 138 based on the detection unit identification information, the package tag management server 11 refers to the LPWA base station table in the position information database 12 to identify the base station. The location information corresponding to the LPWA base station indicated by the information is extracted.

  Then, the package tag management server 11 uses the three-point positioning method based on the extracted spatial position information of the beacon terminal 31 and the radio field strength of the received signal of the advertisement packet of each beacon terminal 31 to obtain each time The coordinate value in the airport facility 300 of the luggage attached electronic tag 13 of information is calculated. In addition, the luggage tag management server 11 notifies the movement locus of the luggage attached electronic tag 13 in the airport facility 300 and the movement locus of the luggage attached electronic tag 13 on the map around the airport on the display screen. . For example, when the baggage is stolen in the airport facility 300, the person in charge performs the above-mentioned operation in the luggage tag management server 11 according to an inquiry from the user to confirm the movement locus of the baggage, and the position of the baggage Can be notified to the user.

Step S113:
The control unit 135 determines whether the time counted after the strength of the reception signal supplied from the LPWA module unit 133 falls below the second threshold exceeds a predetermined time (for example, 30 seconds). Here, when the strength of the reception signal supplied from the LPWA module unit 133 is less than the second threshold, the baggage attached electronic tag 13 is located outside the communication area with the nearest LPWA base station.
At this time, when the counted time exceeds the predetermined time, the control unit 135 determines that reconnection with the LPWA base station can not be performed, starts counting of the communication timer, and advances the process to step S113. On the other hand, when the counted time does not exceed the predetermined time, the control unit 135 determines that there is a possibility of reconnection with the LPWA base station, and advances the process to step S109.

Step S114:
The control unit 135 determines whether the count of the communication timer has become equal to or more than the communication standby time. The communication standby time is, for example, 24 hours, and may be adjusted in accordance with the flight time of the plane on which the user boardes.
At this time, when the count of the communication timer becomes equal to or more than the communication standby time, the control unit 135 advances the process to step S115. On the other hand, when the count of the communication timer becomes equal to or more than the communication standby time, the control unit 135 repeats the process of step S114.

Step S115:
The control unit 135 connects to the mobile communication base station 701B via the mobile communication module unit 134 via the 3G / LTE communication network, and receives a connection confirmation data packet. Then, the control unit 135 sets the base station information included in the connection confirmation data packet as the position information, and writes each of the position information and the time information in the log table of the storage unit 136. That is, only when the package attached electronic tag 13 is located out of the communication area with the beacon terminal and the LPWA base station, the control unit 135 attaches the package through the mobile communication module unit 134 only by the 3G / LTE communication network. The position information of the place where the electronic tag 13 is located is detected, and the process of writing the position information and the time information in the log table of the storage unit 136 is performed.

Step S116:
The control unit 135 detects whether the mobile communication module unit 134 receives an inquiry about location information from the package tag management server 11 via the 3G / LTE communication network.
At this time, when the control unit 135 detects that the mobile communication module unit 134 has received an inquiry about position information, the control unit 135 advances the process to step S117. On the other hand, when the control unit 135 does not detect that the mobile communication module unit 134 has received an inquiry about position information, the control unit 135 advances the process to step S115.

Step S117:
The control unit 135 reads out, from the log table of the storage unit 136, the position information in the latest time information together with the tag identification information of the package-attached electronic tag 13. Then, the control unit 135 adds the detection unit identification information of the control unit 135 to the read time information and position information, and transmits the mobile communication module unit 134 and the 3G / LTE communication network to the package tag management server 11. Send through.

When the detection unit identification information of the control unit 135 is added, the package tag management server 11 refers to the mobile communication base station table in the position information database 12 and reads out the position information corresponding to the base station identification information. Then, the package tag management server 11 notifies the position information at which the package attached electronic tag 13 is currently located by displaying a mark at the coordinate position corresponding to the position information on the map image on the display screen.
For example, when the baggage is loaded on the plane PL1 on which the user is boarded, even if the baggage turns into a lost baggage, it can be known from the location information of the mobile communication base station 701B that the user is at Heathrow Airport similar to the user. .
In addition, if it is loaded on an airplane PL2 different from the plane PL1 on which the user boarded, the baggage becomes a lost bag, and the location information of the mobile communication base station 702B instead of the Heathrow airport on which the user arrived It is understood that the baggage has been carried.
