A large number of wireless devices 110 are prepared at the counter of the luggage storage, and are handed to the user who has stored the luggage. The user carries the wireless device 110 while depositing the luggage and returns the wireless device 110 in exchange for the luggage when receiving the deposited luggage. Here, the wireless device 110 functions as a first wireless device carried by the user. The wireless device 110 is attached with a bar code 111 indicating its own wireless device ID.

  The alarm device 120 issues an alarm when it receives a warning signal to which an ID unique to the alarm device 120 (hereinafter referred to as an alarm device ID) is added. The warning signal is transmitted from the luggage management device 130. The alarm is issued by both the light emission from the light source and the sound generation from the sound source. Initially, only the light may be emitted, and the sound may be emitted after a certain period of time. Initially, only sound may be generated, and light may also be emitted after a certain period of time. The alarm is stopped, for example, by turning off a manual switch. After stopping, no alarm will be issued unless reset. A large number of alarm devices 120 are provided at the counters of the luggage depository and are attached to the luggage deposited by the user. When the user deposits a plurality of packages, each package may be put in one place and the alarm device 120 may be attached to one of the packages. The alarm 120 may be placed at the place where the luggage is, instead of being attached to the luggage. The alarm device 120 is attached with a bar code 121 indicating its own alarm device ID.

  The luggage management device 130 includes a CPU (Central Processing Unit) 131, a ROM (Read Only Memory) 132, a RAM (Random Access Memory), a clock unit 134, an auxiliary storage device 135, an input device 136, a display device 137, and a barcode reader 138. , A first wireless unit 139A and a second wireless unit 139B. Then, the luggage management device 130, via a bus line BL such as an address bus and a data bus, a CPU (Central Processing Unit) 131, a ROM (Read Only Memory) 132, a RAM (Random Access Memory) 133, a clock unit 134, The auxiliary storage device 135, the input device 136, the display device 137, the barcode reader 138, and the first and second wireless units 139A and 139B are connected.

  The CPU 131 corresponds to the central part of the computer. The CPU 131 controls each unit so as to realize various functions as the luggage management device 130 according to the operating system and the application program.

  The ROM 132 corresponds to the main storage part of the computer. The ROM 132 stores the above operating system and application programs. The ROM 132 may store data necessary for the CPU 131 to execute processing for controlling each unit.

The RAM 133 corresponds to the main storage part of the computer. The RAM 133 stores data necessary for the CPU 131 to execute processing. The RAM 133 is also used as a work area in which information is appropriately rewritten by the CPU 131.
The clock unit 134 measures the system time (date, time) of the computer.

  The auxiliary storage device 135 corresponds to the auxiliary storage part of the computer. The auxiliary storage device 135 is, for example, an EEPROM (Electric Erasable Programmable Read-Only Memory), a HDD (Hard Disc Drive), or an SSD (Solid State Drive). The auxiliary storage device 135 stores data used by the CPU 131 for performing various kinds of processing and data generated by the processing by the CPU 131. The auxiliary storage device 135 may store the above application program.

  The input device 136 receives an instruction input by the operator. The display device 137 displays various screens. As the input device 136, for example, a keyboard, a mouse or the like can be used. As the display device 137, for example, a liquid crystal display can be used. The input device 136 and the display device 137 may be integrated using a touch panel.

  The barcode reader 138 optically reads the barcodes 111 and 121 provided on the wireless device 110 and the alarm device 120, respectively.

  The first wireless unit 139A connects the antenna ANT1 and sets the radio wave propagation area of the antenna ANT1 as a wireless communication area. The wireless unit 139A receives a beacon signal transmitted from the wireless device 110 existing in the wireless communication area. The antenna ANT1 is attached near the window of the luggage storage. By using the antenna ANT having directivity, it is possible to set a wide wireless communication area in the directivity direction of the antenna ANT with the window as a reference. By using the antenna ANT having no directivity, the wireless communication area can be set concentrically around the window. Here, the antenna ANT1 and the wireless unit 139A function as a second wireless device arranged near the luggage storage. The wireless unit 139A includes an intensity detection circuit 140. The strength detection circuit 140 detects the strength (db) of the radio wave received by the antenna ANT1.

  The second wireless unit 139B is connected to the antenna ANT2, and sets the radio wave propagation area of the antenna ANT2 as a wireless communication area. The wireless unit 139B sends an activation signal to the alarm device 120 existing in the wireless communication area. As the antenna ANT, in addition to a normal antenna, for example, a leaky coaxial cable laid on the ceiling of a luggage storage space or the like can be applied.

  The input device 136 and the bar code reader 138 are placed in a place where the person in charge of the luggage storage window can operate. The display device 137 is placed in a place where the person in charge of the window or the person in charge of the luggage storage can visually recognize it.

  The baggage management device 130 has three work modes: deposit work, tracking work, and notification work. The luggage management device 130 can perform these three tasks in parallel.

  The custody operation is a task of managing the user and the luggage deposited by the user in association with each other. The tracking business is the business of tracking the behavior of the user who has left the luggage. The notification operation is an operation to notify the person in charge of the window or the like that the user will come to pick up the package. Each job is controlled by a different application program. Further, in executing each task, the package management device 130 requires the conversion table 200 shown in FIG. 2, the package management file 300 shown in FIG. 3, and the tracking file 400 shown in FIG.

  The conversion table 200 is a data table for converting a radio wave intensity (db) when a radio wave from the radio device 110 is received by the antenna ANT1 into a relative distance (m) between the radio device 110 and the antenna ANT1. The relative distance (m) with respect to the radio field intensity (db) is experimentally obtained in advance, and the data is set in the conversion table 200. The conversion table 200 is stored in the ROM 132 or the auxiliary storage device 135.

  The package management file 300 is a data file in which a plurality of records are recorded, with the wireless device ID, the alarm device ID, and the deposit date and time as one record. The package management file 300 is formed in the auxiliary storage device 135 or the RAM 133.

  The tracking file 400 is a data file in which a plurality of records are recorded with the wireless device ID, the radio wave intensity Am (db), the distance Dn (m), the display flag F1 and the warning flag F2 as one record. The trace file 400 is formed in the auxiliary storage device 135 or the RAM 133. The record of the tracking file 400 may further record an alarm device ID associated with the wireless device ID.

Hereinafter, each work will be described step by step. First, the custody service will be described with reference to the flowchart of FIG.
The application program for controlling the custody operation is activated when the luggage management device 130 starts up. When this program is activated, the CPU 131 starts the processing of FIG. First, the CPU 131 waits for a deposit declaration (Act 1). When the input device 136 is a keyboard, the CPU 131 waits for an input of the deposit declaration key assigned to this keyboard. When the input device 136 is a mouse, the CPU 131 waits for the deposit declaration icon displayed on the display device 137 to be clicked.

  When the user who deposits the luggage comes to the window, the window clerk operates the input device 136 to input the deposit declaration key or click the deposit declaration icon. Thus, when the deposit declaration is accepted (YES in Act1), the CPU 131 clears the pair of work memories WM1 and WM2 (Act2). The work memories WM1 and WM2 are formed in the RAM 133.

  The CPU 131 waits for the bar code data to be input (Act 3). When the barcode is read by the barcode reader 138 (YES in Act3), the CPU 131 identifies whether the barcode data is a radio ID or an alarm ID (Act4, 5). Different type flags are incorporated in the radio ID bar code 111 attached to each radio 110 and the alarm ID bar code 121 attached to each alarm 120. By recognizing the type flag, the CPU 131 can identify whether it is the barcode data of the wireless device ID or the barcode data of the alarm device ID.

  When the bar code data is neither the radio device ID nor the alarm device ID (NO in Act 4, NO in Act 5), the CPU 131 waits until the bar code data is input again (Act 3).

  When the barcode data is the wireless device ID (YES in Act4), the CPU 131 stores the wireless device ID in the work memory WM1 (Act6). When the barcode data is the alarm device ID (YES in Act 5), the CPU 131 stores the alarm device ID in the work memory WM2 (Act 7).

  The CPU 131 confirms whether the wireless device ID and the alarm device ID are linked (Act 8). When the wireless device ID and the alarm device ID are stored in the pair of work memories WM1 and WM2, respectively, the CPU 131 determines that they are linked. If only one of them is stored, it is determined that they are not linked. If they are not linked (NO in Act 8), the CPU 131 waits until the bar code data is input again (Act 3).

  When linked (YES in Act 8), the CPU 131 acquires the date and time data measured by the clock unit 134 as the date and time when the luggage was stored from the user (Act 9). The CPU 131 creates a record of the baggage management file 300 from the wireless device ID of the work memory WM1, the alarm device ID of the work memory WM2, and the data of the deposit date and time acquired in the process of Act8. The CPU 131 additionally registers this record in the package management file 300 (Act 10: linking means).

  When the registration of the record in the package management file 300 is completed, the CPU 131 causes the display device 137 to display the guide screen 500 having the layout shown in FIG. 9, for example (Act11). As shown in FIG. 9, a guide message 501 is displayed on the guidance screen 500 to inform the behavior of the person in charge of the window who has kept the luggage from the user. Further, a confirmation button 502 input when the deposit from the user is confirmed, and a cancel button 503 input when the deposit from the user is canceled are displayed. The layout of the guide screen 500 is not limited to that shown in FIG. For example, the confirm button 502 and the cancel button 503 may not be displayed, and these buttons may be keys pre-assigned to the keyboard.

  The person in charge of the window who confirms the guidance screen 500 associates the alarm device 120, which has read the bar code with the bar code reader 138, with the parcel deposited by the user. For example, the window clerk attaches the alarm device 120 to the luggage. Further, the person in charge of the window hands the wireless device 110, which has the barcode read by the barcode reader 138, to the user. Then, the person in charge of the window operates the input device 136 to input the confirm button 502. When the user cancels the baggage deposit, the person in charge of the window operates the input device 136 to input the cancel button 503.

  The CPU 131 that has displayed the guidance screen 500 waits until the cancel button 503 is input or the confirm button 502 is input (Act 12, 13). When the cancel button 503 is input (YES in Act 12), the CPU 131 deletes the latest record registered in the package management file 300 in the process of Act 10 (Act 14). Then, the CPU 131 erases the guide screen 500 (Act 15) and ends the processing after the deposit declaration.

When the confirmation button 502 is input (YES in Act 13), the CPU 131 deletes the guide screen 500 without deleting the record of the package management file 300 (Act 15), and ends the processing after the declaration of deposit. To do.
After that, the CPU 131 waits for the next declaration of deposit (Act 1).

  Next, the pursuit work will be described with reference to the flowcharts of FIGS.

  The application program that controls the tracking work is activated when the package management device 130 is started up. When this program is activated, the CPU 131 starts the processing of FIGS. First, the CPU 131 waits for reception of the wireless device ID (Act 21). When the wireless unit 139A receives the beacon signal periodically transmitted from the wireless device 110, the CPU 131 recognizes that the wireless device ID has been received (YES in Act 21). The CPU 131 confirms whether or not a record including the wireless device ID added to the beacon signal is registered in the package management file 300 (Act 22). If not registered, the received radio ID can be regarded as being transmitted from an unused radio 110. In this case (NO in Act 22), the CPU 131 waits for reception of the next wireless device ID (Act 21).

  When the corresponding record is registered in the package management file 300 (YES in Act 22), the CPU 131 acquires the data of the deposit date and time from the record (Act 23). Then, the CPU 131 calculates an elapsed time t from the deposit date and time to the current date and time measured by the clock unit 134 (Act 24).

  The CPU 131 confirms whether the elapsed time t is longer than the determination time T (Act 25). The determination time T is a time that is sufficient for the user who left the luggage to go out of the wireless communication area of the antenna ANT1, and is set arbitrarily.

  When the elapsed time t is equal to or less than the determination time T, the received wireless device ID can be regarded as being transmitted from the wireless device 110 carried by the user who has just checked in the luggage. In this case (NO in Act 25), the CPU 131 waits for reception of the next wireless device ID (Act 21).

  When the elapsed time t is longer than the determination time T, the received wireless device ID can be regarded as being transmitted from the wireless device 110 carried by the user who came to receive the package. In this case (YES in Act 25), the CPU 131 acquires the radio wave intensity An (db) detected by the intensity detection circuit 140 (Act 26).

  If the radio wave intensity An (db) can be acquired, the CPU 131 searches the tracking file 400 (Act 27). Then, the CPU 131 confirms whether or not the record including the received wireless device ID is registered in the tracking file 400 (Act 28). If not registered, the received wireless device ID can be regarded as being transmitted from the wireless device 110 carried by the user who has just entered the wireless communication area of the antenna ANT1. In this case (NO in Act 28), the CPU 131 registers a record including the wireless device ID and the radio wave intensity An (db) in the tracking file 400 (Act 29). The CPU 131 resets the display flag F1 of this record to "0" (Act 33). The CPU 131 resets the warning flag F2 of this record to "0" (Act36). The CPU 131 converts the radio field intensity An (db) into a relative distance Dn (m) between the wireless device 110 and the antenna ANT1 by referring to the conversion table 200 (Act 38), and the CPU 131 then calculates the relative distance Dn (m). Is recorded in the record (Act 39). This is the end of the process after receiving the wireless device ID.

  When a record including the received wireless device ID is registered in the tracking file 400, it is determined that the received wireless device ID is transmitted from the wireless device 110 carried by the user who moves within the wireless communication area of the antenna ANT1. Can be considered In this case (YES in Act 28), the CPU 131 reads the radio wave intensity Am (db) recorded in that record (Act 30). Then, the CPU 131 compares the radio wave intensity Am (db) with the radio wave intensity An (db) acquired in the process of Act 26 (Act 31: confirmation means).

  When the radio field intensity An (db) is less than or equal to the radio field intensity Am (db), that is, when the radio field intensity becomes weaker with time, the user can be considered to be moving away from the baggage deposit window. In this case (NO in Act31), the CPU 131 resets the display flag F1 of this record to "0" (Act33). The CPU 131 resets the warning flag F2 of this record to "0" (Act36). The CPU 131 converts the radio field intensity An (db) into a relative distance Dn (m) between the wireless device 110 and the antenna ANT1 by referring to the conversion table 200 (Act 38), and the CPU 131 then calculates the relative distance Dn (m). Is recorded in the record (Act 39). This is the end of the process after receiving the wireless device ID.

  When the radio wave intensity An (db) is larger than the radio wave intensity Am (db), that is, when the radio wave intensity becomes stronger with the passage of time, the user can be considered to be approaching the window of the luggage storage. In this case (YES in Act31), the CPU 131 confirms whether or not the radio field intensity An (db) is larger than the first threshold value As1 (db) (Act32: confirmation means). The first threshold value As1 (db) is the radio wave reception intensity from the wireless device 110 when the relative distance from the antenna ANT1 is 50 m, for example.

  When the radio wave intensity An (db) is less than or equal to the first threshold value As1 (db), it can be considered that the user has not approached within 50 m from the window. In this case (NO in Act 32), the CPU 131 resets the display flag F1 of the record including the received wireless device ID to “0” (Act 33). The CPU 131 resets the warning flag F2 of this record to "0" (Act36). The CPU 131 converts the radio wave intensity Am (db) into the relative distance Dn (m) between the radio device 110 and the antenna ANT1 by referring to the conversion table 200 (Act 38), and the CPU 131 then calculates the relative distance Dn (m). Is recorded in the record (Act 39). This is the end of the process after receiving the wireless device ID.

  When the radio wave intensity An (db) is larger than the first threshold value As1 (db), the user can be considered to be within 50 m from the window. In this case (YES in Act32), the CPU 131 sets the display flag F1 of the record including the received wireless device ID to "1" (Act34).

  Next, the CPU 131 confirms whether the radio field intensity An (db) is larger than the second threshold value As2 (db) (Act 35: confirmation means). The second threshold value As2 (db) is the radio wave reception intensity from the wireless device 110 when the relative distance from the antenna ANT1 is 30 m, for example.

  When the radio wave intensity An (db) is equal to or lower than the second threshold value As2 (db), it can be considered that the user is not within 30 m from the window. In this case (NO in Act 35), the CPU 131 resets the warning flag F2 of the record including the received wireless device ID to “0” (Act 36). The CPU 131 converts the radio wave intensity Am (db) into the relative distance Dn (m) between the radio device 110 and the antenna ANT1 by referring to the conversion table 200 (Act 38), and the CPU 131 then calculates the relative distance Dn (m). Is recorded in the record (Act 39). This is the end of the process after receiving the wireless device ID.

  When the radio wave intensity An (db) is larger than the threshold value As2 (db), it can be considered that the user is approaching within 30 m from the window. In this case (YES in Act 35), the CPU 131 sets the warning flag F2 of the record including the received wireless device ID to “1” (Act 37). The CPU 131 converts the radio wave intensity Am (db) into the relative distance Dn (m) between the radio device 110 and the antenna ANT1 by referring to the conversion table 200 (Act 38), and the CPU 131 then calculates the relative distance Dn (m). Is recorded in the record (Act 39). This is the end of the process after receiving the wireless device ID.

After that, the CPU 131 waits for reception of the next wireless device ID (Act 21).
The first threshold value As1 and the second threshold value As2 can be arbitrarily set as long as the relationship of As1 <As2 is maintained.

  Next, the notification work will be described with reference to FIG.

  The application program for controlling the notification work is activated in response to an interrupt signal generated at a predetermined interval (for example, 1 second interval). When this program is activated, the CPU 131 starts the processing of FIG. First, the CPU 131 searches the warning flag F2 of each record recorded in the tracking file 400 (Act 41). Then, the CPU 131 confirms whether there is a record in which the warning flag is set to "1" (Act 42).

  If there is a record in which the warning flag is set to "1", that record is a warning target record. In this case (YES in Act 42), the CPU 131 searches the package management file 300 with the wireless device ID of the record and detects the alarm device ID associated with the wireless device ID (Act 43). The CPU 131 transmits a warning signal including this alarm ID from the antenna ANT2 via the wireless unit 139B (Act44: control means).

  If there are a plurality of records in which the warning flag is set to “1”, the CPU 131 searches the package management file 300 with the wireless device ID of each record and finds the alarm device ID associated with the wireless device ID. Detect all. Then, the CPU 131 may transmit a warning signal including each alarm ID from the antenna ANT2 via the wireless unit 139B in a time division manner.

  When the alarm signal including the alarm ID is transmitted, the alarm 120 to which the alarm ID is set issues an alarm by sound and light. The baggage to which the alarm device 120 for which an alarm has been issued is attached is a baggage deposited by a user approaching within 30 m from the window. Therefore, the person in charge of the window or the person in charge of the luggage storage can find the luggage deposited by the user and carry it to the window before the user comes to the window. As a result, it is possible to shorten the time required to deliver the parcel at the counter, so that the efficiency of the counter operation can be improved.

  After transmitting the warning signal, or when there is no warning target record (NO in Act 42), the CPU 131 searches the display flag F1 of the tracking file 400 (Act 45). Then, the CPU 131 confirms whether or not there is a record whose display flag is set to "1" (Act46). If there is no record in which the display flag is set to "1" (NO in Act46), the process ends.

  If there is a record whose display flag is set to "1", that record is a record to be displayed. In this case (YES in Act 46), the CPU 131 acquires the wireless device ID and the distance Dn from the record. At this time, when there are a plurality of records in which the display flag is set to “1”, the wireless device ID and the distance Dn are acquired from each record (Act 47). The CPU 131 causes the display device 137 to display the notification screen 600 having the layout shown in FIG. 10, for example, based on the data acquired from the tracking file 400 (Act 48).

  As shown in FIG. 10, on the notification screen 600, a wireless device ID 601 and an indicator 602 indicating the distance Dn (m) are displayed in association with each other. The distance is based on 50 m, which is the relative distance from the antenna ANT1 corresponding to the first threshold value As1 (db), and the indicator is displayed so as to become longer as the distance becomes shorter than this reference value. Therefore, the person in charge of the counter or the person in charge of the luggage storage who has confirmed the notification screen 600 can provide information about how many users are coming to receive the luggage and how close they are to the counter. It can be visually confirmed. As a result, when many users are coming to receive the parcel, it is possible to take appropriate measures in advance such as increasing the number of persons in charge at the counter and preparing, so that the counter work can be processed more efficiently.

  The layout of the notification screen 600 is not limited to that shown in FIG. For example, regarding the distance, the numerical value of the distance may be displayed as it is instead of the indicator. Further, instead of displaying the wireless device ID, the alarm device ID associated with the wireless device ID may be displayed.

(Second embodiment)
FIG. 11 is a schematic diagram showing the overall configuration of the package management system 100-2 according to the second embodiment. The same parts as those of the first embodiment shown in FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted.

  The luggage management system 100-2 includes a plurality of communication terminals 150, a plurality of alarm devices 120, and a luggage management device 160.

The condition is to have. Further, the wireless communication function can detect the intensity of the received radio wave. The communication terminal 150 is owned by a user who uses the luggage storage. Before using the luggage depository, the user installs a dedicated application program (hereinafter referred to as a luggage management program) on the communication terminal 150 using the Internet or the like.

  In addition to the CPU 131, the ROM 132, the RAM 133, the clock unit 134, the auxiliary storage device 135, the input device 136, the display device 137, the bar code reader 138, the first wireless unit 139A, and the second wireless unit 139B, the luggage management device 160 includes , NFC unit 161. The NFC unit 161 is connected to the bus line BL.

  The NFC unit 161 performs data communication according to the NFC standard with the NFC-compatible device held by the luggage management device 160. In this embodiment, the communication terminal 150 is an NFC compatible device.

  Similar to the first embodiment, the luggage management device 160 has three business modes of deposit business, tracking business, and notification business. Regarding the notification work, the procedure similar to that of the package management device 130 of the first embodiment is used. Regarding the custody service and the tracking service, the processing procedure is different from that of the luggage management device 130. Therefore, the custody service and the tracking service of the luggage management device 160 will be described below. First, the custody service will be described with reference to the flowchart of FIG.

  It should be noted that the package management device 160 needs the conversion table 200 shown in FIG. 2, the package management file 300 shown in FIG. 3, and the tracking file 400 shown in FIG. 4 to execute each task. There is no.

  The application program for controlling the custody operation is activated when the luggage management device 160 starts up. When this program is activated, the CPU 131 starts the processing of FIG. First, the CPU 131 waits for a deposit declaration (Act 51). When the deposit declaration is accepted (YES in Act 51), the CPU 131 clears the pair of work memories WM1 and WM2 (Act 52).

  The CPU 131 controls the NFC unit 161 to issue a terminal ID request command (Act 63). With this command, the luggage management device 160 can receive the terminal ID set in the NFC-compatible device provided near the NFC unit 161. Therefore, the person in charge of the window holds the communication terminal 150 of the user who deposits the luggage near the NFC unit 161. Then, the terminal ID preset in the communication terminal 150 is transmitted from the communication terminal 150 to the package management device 160 by NFC communication.

  The CPU 131 waits for reception of the terminal ID (Act 54). During this standby, the CPU 131 measures the elapsed time from the transmission of the request command with a timer and monitors whether or not it has timed out (Act 55). When a time-out occurs before receiving the terminal ID (YES in Act 55), the CPU 131 causes the display device 137 to display that the communication terminal 150 is not compatible with the luggage management system 100-2 (Act 56). This is the end of the processing after the declaration of deposit.

  When the terminal ID is received via the NFC unit 161 before the time-out (YES in Act 54), the CPU 131 stores the terminal ID in the work memory WM1 (Act 57).

  The CPU 131 waits for the bar code data to be input (Act 57). When the barcode is read by the barcode reader 138 (YES in Act 57), the CPU 131 confirms whether or not the barcode data is an alarm ID (Ac58). When the barcode data is not the alarm ID (NO in Act 58), the CPU 131 waits until the barcode data is input again (Act 57). When the barcode data is the alarm device ID (YES in Act 58), the CPU 131 stores the alarm device ID in the work memory WM2 (Act 59).

  After that, the CPU 131 executes the same processing as Act9 to Act15 in the deposit service of the first embodiment (Act61). Through this process, the CPU 131 associates the terminal ID of the communication terminal 150 carried by the user with the alarm ID of the alarm 120 attached to the luggage checked by the user. Then, the CPU 131 creates a record of the package management file 300 including the terminal ID, the alarm ID, and the deposit time, and registers this record in the package management file 300. This is the end of the processing after the declaration of deposit.

  Next, the pursuit work will be described with reference to the flowcharts of FIGS. 13 and 14. 13, the flow chart on the right side shows the processing procedure executed by the CPU 131 of the luggage management device 160, and the flow chart on the left side shows the processing procedure executed by the processor of the communication terminal 150 according to the luggage management program. Is shown.

  The application program for controlling the tracking work is activated when the luggage management device 160 starts up. When this program is activated, the CPU 131 starts the processing shown in FIGS. First, the CPU 131 transmits a terminal ID inquiry command from the antenna ANT1 via the wireless unit 139A (Act 71).

  The processor of the communication terminal 150 in which the package management program is activated waits for an inquiry command (Act 91). When the inquiry command is received by the wireless communication function (YES in Act 91), the processor acquires the received radio wave intensity An (Act 92). Then, the processor compares the previous value of the received radio wave intensity stored in the previous value memory with the present received radio wave intensity An (Act 93). The initial value of the previous value memory is infinite.

  When the received radio wave intensity An is less than or equal to the previous value (NO in Act93), the processor rewrites the value in the previous value memory with the current value (Act95). When the received radio wave intensity An is larger than the previous value (YES in Act93), the processor generates a response command including the radio wave reception intensity An and its own terminal ID. Then, the processor transmits this response command to the package management device 160 which is the transmission source of the inquiry command by the wireless communication function (Act94). After that, the processor rewrites the value of the previous value memory with the current value (Act95).

  In this way, the communication terminal 150 implementing the package management program acquires the radio wave reception intensity An each time it receives an inquiry command while existing in the wireless communication area of the antenna ANT1, and stores the latest value in the previous value memory. Remember. Then, each time the radio wave reception intensity An becomes strong, the communication terminal 150 transmits a response command including the radio wave reception intensity An and its own terminal ID to the luggage management device 160. Here, the communication terminal 150 functions as a first wireless device that transmits a unique ID in response to reception of a radio wave transmitted from the second wireless device (radio unit 139A, antenna ANT1).

  The CPU 131 that has transmitted the inquiry command waits for a response command from the communication terminal 150 (Act 72). When the response command is received (YES in Act 72), the CPU 131 confirms whether or not the terminal ID included in the response command is registered in the package management file 300 (Act 73). If not registered, it can be considered that the received terminal ID is transmitted from the communication terminal 150 carried by a person who has not checked in the luggage. In this case (NO in Act 73), the CPU 131 waits for reception of the next terminal ID (Act 72).

  When the terminal ID included in the response command is registered in the package management file 300 (YES in Act 73), the CPU 131 acquires the data of the deposit date and time from the record including the terminal ID (Act 74). Then, the CPU 131 calculates the elapsed time t from the deposit date and time to the current date and time measured by the clock unit 134 (Act 75).

  The CPU 131 confirms whether the elapsed time t is longer than the determination time T (Act 76). When the elapsed time t is equal to or less than the determination time T, the received terminal ID can be regarded as being transmitted from the communication terminal 150 carried by the user who just deposited the luggage. In this case (NO in Act 76), the CPU 131 waits for reception of the next terminal ID (Act 72).

When the elapsed time t is longer than the determination time T, the received terminal ID can be regarded as being transmitted from the communication terminal 150 carried by the user who has received the parcel. In this case (YES in Act 76), the CPU 131 acquires the radio wave reception intensity An from the received response command. Then, the CPU 131 refers to the conversion table 200 and converts the radio wave intensity An (db) into the relative distance Dn (m) between the communication terminal 150 and the antenna ANT1 (Act 77).

  The CPU 131 searches the tracking file 400 (Act 78). Then, it is confirmed whether or not the record including the received terminal ID is registered in the tracking file 400 (Act 79). If not registered, the received terminal ID can be regarded as transmitted from the communication terminal 150 carried by the user who has just entered the wireless communication area of the antenna ANT1. In this case (NO in Act 79), the CPU 131 registers the record including the terminal ID in the tracking file 400 (Act 80). The CPU 131 resets the display flag F1 of this record to "0" (Act 82). The CPU 131 resets the warning flag F2 of this record to "0" (Act85). The CPU 131 records the relative distance Dn (m) in the record (Act 87). This is the end of the process after receiving the terminal ID.

  When the record including the received terminal ID is registered in the tracking file 400, it is assumed that the received terminal ID is transmitted from the communication terminal 150 carried by the user who moves within the wireless communication area of the antenna ANT1. You can In this case (YES in Act 79), the CPU 131 confirms whether or not the relative distance Dn (m) acquired in the process of Act 77 is larger than the first threshold value Ds1 (for example, 50 m) (Act 81: confirmation means). ).

  When the relative distance Dn (m) is equal to or larger than the first threshold value Ds1 (NO in Act81), the CPU 131 resets the display flag F1 of the record including the received terminal ID to "0" (Act82). The CPU 131 resets the warning flag F2 of this record to "0" (Act85). The CPU 131 records the relative distance Dn (m) in the record (Act 87). This is the end of the process after receiving the terminal ID.

  When the relative distance Dn (m) is smaller than the first threshold value Ds1 (YES in Act81), the CPU 131 sets the display flag F1 of the record including the received terminal ID to “1” (Act83).

  Next, the CPU 131 confirms whether or not the relative distance Dn (m) is larger than the second threshold value Ds2 (for example, 30 m) (Act84: confirmation means). When the relative distance Dn (m) is equal to or larger than the second threshold value Ds2 (NO in Act84), the CPU 131 resets the warning flag F2 of the record including the received terminal ID to "0" (Act85). The CPU 131 records the relative distance Dn (m) in the record (Act 87). This is the end of the process after receiving the terminal ID.

  When the relative distance Dn is smaller than the second threshold value Ds2 (YES in Act84), the CPU 131 sets the warning flag F2 of the record including the received terminal ID to "1" (Act86). The CPU 131 records the relative distance Dn (m) in the record (Act 87). This is the end of the process after receiving the terminal ID.

  The notification work is the same as in the first embodiment. Therefore, also in the second embodiment, it is possible to shorten the time required to deliver the parcel and improve the efficiency of the window work.

  Moreover, in the case of the second embodiment, since the communication terminal 150 such as the smartphone owned by the user can be used as the first wireless device, it is not necessary to prepare the wireless device 110. Alternatively, the wireless device 110 and the communication terminal 150 may be used in combination, but even in that case, the number of the wireless devices 110 can be reduced, so that the cost required for constructing the system can be reduced.

The present invention is not limited to the above embodiment.
In the tracking work of the first embodiment, the radio wave reception intensity is compared with a threshold value. On the other hand, in the tracking work of the second embodiment, the radio wave reception intensity is converted into distance data, and this distance data is compared with a threshold value. In the tracking operation of the first embodiment, the radio wave reception intensity may be converted into distance data and this distance data may be compared with a threshold value. Similarly, in the second embodiment, the radio wave reception intensity may be compared with the threshold value.

  Further, the method of confirming whether the relative distance between the first wireless device and the second wireless device is shorter than a predetermined distance is not limited to the method using the radio wave reception intensity. The point is that the relative distance between the first wireless device and the second wireless device can be obtained.

  Further, in the above-described embodiment, the first wireless unit 139a and the second wireless unit 139b are provided, but these wireless units may be integrated into one. In that case, while using an existing method such as Bluetooth (registered trademark) as a communication method, communication with the wireless device 110 or the communication terminal 150 is unidirectional communication, and communication with the alarm device 120 is bidirectional. It may be data communication for all. Further, in order to secure a long communication distance with the wireless device 110 or the communication terminal 150, a diversity antenna may be used as the antenna ANT1.
