Description

The present invention relates to a package with a removal detection function, a removal detection method, and a program.

Conventionally, the delivery status of a package to its destination has been confirmed by a tracking system provided by the carrier that delivers the package.
However, after the package has been delivered to the destination, it is difficult for even the delivery company to confirm whether the package has been opened.
Therefore, there is a detection device that has an opening detection function that notifies the user that the package has been opened after the package has been delivered (see, for example, Patent Document 1).

First Embodiment
Hereinafter, a description will be given of a package with removal detection function according to a first embodiment of the present invention with reference to the drawings. Fig. 1 is a diagram showing an example of the configuration of a package with removal detection function according to the first embodiment of the present invention. In Fig. 1, the depth direction (vertical width direction) in which contents 200 are inserted into a package 11 of a package with removal detection function 1 is the Z direction, the thickness direction of the package 11 is the Y direction, and the width direction of the package 11 is the X direction.

Fig. 1A shows an example of the configuration of a removal detection device provided in a package with removal detection capabilities. The cross section of the package with removal detection capabilities in Fig. 1A is a cross section perpendicular to the X direction.
FIG. 1B shows a cross-sectional view (a cross-section perpendicular to the Z direction) of a package with removal detection capabilities.

In FIG. 1A , the removal detection device 100 includes a start-up unit 101 , a data detection unit 102 , a removal detection unit 103 , an information output unit 104 , a transmission unit 105 , a storage unit 106 , and a battery 107 .
The start-up unit 101 turns on a start-up switch (not shown) provided on any of the packaging bodies 11, thereby supplying power from the battery 107 to the removal detection device 100 and each of the capacitance sensors 12 serving as a sensor unit, thereby starting up the removal detection device 100.
For example, when a user purchases the removal detection package 1, the activation switch is in the OFF state, and the activation switch is turned ON after inserting the contents into the storage area of the removal detection package 1. As a result, when the removal detection package is on sale, power is not supplied from the battery 107 to the removal detection device 100 and the capacitance sensor 12, and no power is consumed.

The data detection unit 102 detects the capacitance value of the capacitance sensor 12 (described later) via the signal line S1 (detection based on the frequency of the CR oscillator) and outputs the capacitance value (or frequency) as detection information to the removal detection unit 103.

The removal detection unit 103 compares a set value (a reference capacitance value or a reference frequency) stored in the storage unit 106 with the above capacitance value (or the reference frequency).
If the detection information is less than the set value, i.e., if the capacity value is less than the reference capacity value, the removal detection unit 103 determines that the contents have been removed from the storage area of the package 1 with removal detection function.
On the other hand, if the detection information is greater than or equal to the set value, i.e., if the capacity value is greater than or equal to the reference capacity value, the removal detection unit 103 determines that the contents have not been removed from the storage area of the packaging body 1 with removal detection function.

When the removal detection unit 103 determines that the contents 200 have been removed from the packaging body 11, the information output unit 104 transmits removal information via the transmission unit 105 as removal information indicating that the contents 200 have been removed from the packaging body 11.
In addition, when the removal detection unit 103 determines that the contents 200 have not been removed from the packaging body 11, the information output unit 104 transmits, via the transmission unit 105, non-removal information as removal information indicating that the contents 200 have not been removed from the packaging body 11.

The transmitter 105 has a wireless module, such as a LPWA (Low Power Wide Area) module, such as Sigfox (registered trademark), LoRa (registered trademark), or ZETA (registered trademark). LPWA consumes very little power during transmission and reception, and is a communication method suitable for long-distance communication of small data size information. There are several known LPWA methods, and any method may be used. Preferably, a standard that allows data to be transmitted over a long distance (a distance of several tens of kilometers to about 100 kilometers) is preferable. Note that, as a communication method, a method other than LPWA or a method with a different wavelength may be used. Furthermore, in the case of two-way communication, a wavelength other than LPWA may be used as a receiving wave. In addition, when two-way communication is required, a data receiver compatible with the LPWA method is provided in the removal detection device 100. Provided in the removal detection device 100. Note that, since standby power is generated even when no communication is performed, it is necessary to have a battery from the time the sender sends the package 1 with removal detection function until the recipient receives it. In this regard, ZETA, which is one of the LPWA methods, has the advantage of consuming less standby power than other methods, making it a more preferable communication method to use in the packaging unit 1 with removal detection function of the present invention.

In addition, in order to increase the reach of data, communication may be performed via a relay station or a repeater of a base station. Furthermore, the time when the communicated data passes through a relay station or a base station may be acquired and stored in a server (not shown) together with the removal information. For example, in the case of ZETA (registered trademark), when the removal information transmitted by the transmitting unit 105 is received by an AP (access point) which is a base station or a relay station, the time of reception may be added to the removal information as the time transmitted from the package 11, and the information may be transmitted to a predetermined removal detection (or tracking) server (not shown).
Furthermore, location information acquired by a location detection method described later may be added to the removal information and transmitted to a predetermined removal detection (or tracking) server (not shown).
As described above, the removal detection (or tracking) server can acquire the time (date and time) when the content 200 was removed from the package 1 with a removal detection function and the location of the package 1 with a removal detection function together with the removal information as removal information. In other words, it is possible to easily confirm where and when the content 200 was removed from the package 11.

In addition, a predetermined removal detection (or tracking) server (not shown) may notify the user who sent the package with removal detection function 1 of the time and place when the removal information was received by automatically sending an email or the like. This allows the user to confirm that the package with removal detection function 1 that was sent has been opened and the contents 200 have been removed from the package with removal detection function 1, and the place where the package with removal detection function 1 was opened. In other words, the user can confirm that the package with removal detection function 1 was opened at the destination and that the recipient picked up the contents 200.

Figure 2 is a diagram showing an example of the configuration of the format of a transmission signal used when transmitting extraction information according to an embodiment. The transmission signal is composed of, for example, a header HD, a data section DA, and a footer FT. The header HD is information attached to the beginning of the signal SG, and is composed of, for example, a notification source ID, a notification destination ID, and a signal type. The notification source ID is identification information of the device that is the notification source. The notification destination ID is identification information of the device that is the notification destination. The data section DA is information indicating the content to be notified, and is, for example, information that combines information that has been blocked for each specified data length, such as notification content 1, ..., notification content K. The footer FT is information attached to the end of the signal, and is, for example, a cyclic redundancy code (CRC (Cyclic Redundancy Code)) for error detection.

For example, the header HD of the transmitted signal indicates that the notification source is the removal detection package 1, the notification destination is a specified removal detection (or tracking) server (not shown), and the signal type is removal information. The data section DA indicates information indicating identification information for identifying the removal detection package 1, the time (date and time) when it was removed, the position of the removal detection package 1, and the time (date and time) when the position was estimated. The footer FT indicates, for example, a CRC bit generated from the bit string in the data section DA. Furthermore, notification content 1 indicates individual identification information of the removal detection package 1, and notification content 2 indicates information such as removal information.

Then, a specified removal detection (or tracking) server (not shown) identifies the user who sent the package with removal detection function 1 by the individual identification information (the above-mentioned notification source ID) that identifies the package with removal detection function 1, and transmits to the user the position of the package with removal detection function 1 during delivery and the time when the position was detected, as well as the above-mentioned removal information of the package with removal detection function 1. In this case, the user needs to access the removal detection (or tracking) server (not shown) from, for example, their own terminal (such as a personal computer or smartphone), and perform a process to associate their own email address with the individual identification information (notification source ID) of the package with removal detection function 1 they used.

The memory unit 106 stores in advance the program that controls the entire removal detection device 100, as well as settings that are compared with the detection information.

The battery 107 is a battery that supplies power to the removal detection device 100 and the capacitance sensor 12. In order to reduce the overall thickness of the package 1 with removal detection function, it is desirable for the battery 107 to be a thin battery with a thickness similar to that of paper, or a paper battery that is a thin battery that can be bent like paper.

Next, a mounting configuration of the capacitance sensor 12 to the packaging body 11 will be described with reference to FIGS.
A first electrode 12_1 is disposed (attached) to an inner surface 11S1 of the packaging body 11. A second electrode 12_2 is disposed on an inner surface 11S2 opposed to the inner surface 11S1 of the packaging body 11. Here, the first electrode 12_1 and the second electrode 12_2 are disposed at positions where they overlap on the inner surface 11S1 and the inner surface 11S2, respectively, in a plan view.
The fixing jig 13 separates the first electrode 12_1 and the second electrode 12_2 at a predetermined distance, and this separated portion becomes the storage area 14. Note that the fixing jig 13 may not be necessary if the packaging body 11 itself is made of a strong material such as cardboard, or if the packaging body 11 itself has a three-dimensional self-supporting structure, and so on, allowing the first electrode 12_1 and the second electrode 12_2 to be separated at a predetermined distance.

The capacitance sensor 12 is composed of a first electrode 12_1 and a second electrode 12_2 arranged opposite to the first electrode 12_1. Signal lines S1 corresponding to the first electrode 12_1 and the second electrode 12_2 are each connected to a data detection unit 102.
In addition, the first electrode 12_1 and the second electrode 12_2 are disposed in the accommodation region 14 at a predetermined distance on the opposing inner surfaces 11S1 and 11S2, respectively, and at positions that overlap in a plan view.

Therefore, contents such as documents, paper, objects, etc. are inserted between the first electrode 12_1 and the second electrode 12_2 in the storage area 14. That is, the dielectric constant differs between the case where only air is present between the first electrode 12_1 and the second electrode 12_2 and the case where paper, etc. is inserted, and this changes the capacitance value of the capacitance sensor 12. Generally, paper has a higher dielectric constant than air.
By detecting the change in capacitance value corresponding to this difference in dielectric constant, i.e., by detecting whether the capacitance value of the capacitance sensor 12 is less than a set value, the presence or absence of contents 200 such as documents or paper in the storage area 14 can be detected.

As described above, in this embodiment, the capacitance sensor 12 has a first electrode 12_1 and a second electrode 12_2, and detects the presence or absence of contents 200 in the storage area 14, i.e., whether or not the contents 200 have been removed from the packaging body 11, based on a change in capacitance due to the presence or absence of contents 200 between each of the first electrode 12_1 and the second electrode 12_2.
In addition, the capacitance sensor 12 may be configured such that, for example, only the first electrode 12_1 is placed in the storage area 14, and the change in capacitance due to the difference in stray capacitance depending on the presence or absence of contents 200 is detected, thereby detecting the presence or absence of contents in the storage area 14, i.e., whether or not the contents 200 have been removed from the packaging body 11.

FIG. 3 is a flow chart showing an example of an operation of the removal detection function-equipped package 1 according to the first embodiment of the present invention for processing removal of contents from the package.
Step S101:
The user performs a process to send (by mail or delivery service, etc.) the package 1 with removal detection function.
At this time, when the user uses the obtained package 1 with removal detection function, the user inserts the contents 200 into the storage area 14 and then closes the seal of the package 11 .

Step S102:
When the removal detection function-equipped package 1 is to be delivered, an activation switch disposed anywhere on the package 11 is turned on.
Also, a mechanism may be provided that turns on the start switch when the package 11 is sealed.
As a result, the battery 107 starts supplying power to the removal detection device 100 and the capacitance sensor 12 .

Step S103:
The information output unit 104 counts time and determines whether or not a predetermined time has elapsed. If the predetermined time has elapsed, the information output unit 104 advances the process to step S104. On the other hand, if the predetermined time has not elapsed, the information output unit 104 repeats the process of step S103.

Step S104:
The information output unit 104 acquires detection information from the removal detection unit 103 indicating whether it has been determined that the contents 200 have been removed or not, i.e., confirms whether the contents 200 have been removed.

Step S105:
Then, the information output unit 104 refers to the detection information from the removal detection unit 103 and determines whether or not it indicates that the content 200 has been removed.
If the information output unit 104 determines that this indicates that the content 200 has been removed, the process proceeds to step S106.
On the other hand, if the information output unit 104 determines that this indicates that the content 200 has not been removed, the process proceeds to step S107.

Step S106:
When the information output unit 104 determines that the contents 200 have been removed from the packaging body 11 in accordance with the detection information, it transmits removed information as removal information indicating that the contents 200 have been removed from the packaging body 11 to the removal detection (or tracking) server via the transmission unit 105.
In addition, the information output unit 104 ends the process of removing the contents 200 from the package 11 in the package 1 with removal detection function.
When the removal detection (or tracking) server detects that the contents 200 have been removed from the package 1 with removal detection function, it may detect the position of the package 1 with removal detection function and the time.
This makes it possible to obtain information regarding when and where the contents 200 were removed from the package 1 with removal detection function.

When communicating with the retrieval detection (or tracking) server from the transmitting unit 105, a repeater or a base station may be used as a relay. In this case, time information of the repeater or the base station when passing through the repeater or the base station is transmitted together with the retrieval completion information to the retrieval detection (or tracking) server, so that the transmission time of the retrieval completion information can be obtained.
It is preferable to use ZETA, which is one of the LPWA standards, for communication by the transmitting unit 105. When ZETA is used, since ZETA employs a mesh network, if there is access concentration at the base station of the intended communication destination, communication to other repeaters or base stations will start without waiting. Therefore, data delay from the transmitting unit 105 to the repeater or base station can be reduced, making it easier to obtain the time when the retrieval information is transmitted in real time, and reducing the difference between the actual retrieval time and the time when the base station receives it.

Step S107:
When it is determined that the contents 200 have not been removed from the package 11 in response to the detection information, the information output unit 104 transmits non-removal information as removal information indicating that the contents 200 have not been removed from the package 11 to the removal detection (or tracking) server via the transmission unit 105. The non-removal information may be only information indicating that the contents 200 have not been removed from the package 11, or may include location information of the package 1 with removal detection function at the time of transmission.

In addition, the removal detection (or tracking) server obtains the current location of the packaging body 1 with removal detection function and information as to whether the contents 200 have been removed from the packaging body 11 based on the removal information obtained from the packaging body 1 with removal detection function via the AP and the base station.
In other words, each of multiple APs (three or more locations) located in close proximity to the transmitter 105 of the packaging 1 with removal detection function receives, for example, the removal information transmitted from the packaging 1 with removal detection function, and forwards this removal information to the base station along with the time at which it was received.
The removal detection (or tracking) server then uses three-point positioning technology to estimate the current location of the package 1 with removal detection function from the positions of each of the multiple APs and the difference in the time information added to the removal information received from each of these APs.

In addition, the location information of any one of the nearest APs (repeater, base station, etc.) that received the removal information from the removal detection package 1 may be configured as the location information of the removal detection package 1. By making the location of the nearest repeater or base station known information, it becomes possible to easily estimate the approximate location information of the removal detection package 1.

In addition, each of the multiple (three or more) APs may be configured to receive removal information transmitted from a package 1 with a removal detection function, for example, and upon receiving this removal information, measure the radio wave strength of this removal information, add information on the measured radio wave strength (radio wave strength information) to the removal information, and transfer it to the base station.
In this configuration, the removal detection (or tracking) server uses three-point positioning technology to estimate the current location of the package 1 with removal detection function from the positions of each of the multiple APs and the radio wave intensity information attached to the removal information received from each of these APs.

Figure 4 is a diagram explaining the process by which the removal detection (or tracking) server estimates the position of the removal detection package 1. The removal detection (or tracking) server, for example, causes each AP to communicate with the same removal detection package 1 at approximately the same time and measures the signal arrival time of each AP. The removal detection (or tracking) server extracts candidates for the position of the removal detection package 1 based on the signal arrival time of each AP.

For example, the removal detection (or tracking) server calculates the signal reach based on the signal reach of each of multiple APs in relation to the signal speed (speed of light). The signal reach is the distance it takes for a signal transmitted from each AP to reach the package with removal detection function 1, and is synonymous with the distance from the AP to the package with removal detection function 1. The removal detection (or tracking) server determines positions on a circumference with each AP as the center and with a radius equal to the signal reach of each AP as candidates for the location of the package with removal detection function 1.

In the example of FIG. 4, the signal arrival time measured by AP20-1 is 0.2 seconds, and the position on circumference R1 is a candidate for the location of the removal detection package 1. The signal arrival time measured by AP20-2 is 0.1 seconds, and the position on circumference R2 is a candidate for the location of the removal detection package 1. The signal arrival time measured by AP20-3 is 0.5 seconds, and the position on circumference R3 is a candidate for the location of the removal detection package 1. The removal detection (or tracking) server estimates the location of the removal detection package 1 as the location where the candidates for the location of the removal detection package 1 extracted based on the signal arrival distances measured by each of the multiple APs intersect. In this example, the point where circumferences R1 to R3 intersect is the estimated location of the removal detection package 1.

In the above, an example was described in which the removal detection (or tracking) server estimates the position of the removal detection package 1 based on the signal arrival times measured by each of the three APs 20-1 to 20-3. However, this is not limiting. The removal detection (or tracking) server may estimate the position of the removal detection package 1 based on the signal arrival times measured by each of four or more APs. The removal detection (or tracking) server may estimate the position of the removal detection package 1 based on one or two signal arrival times. In this case, for example, the removal detection (or tracking) server overlays the candidate position of the removal detection package 1 extracted based on the signal arrival distance measured by each AP with a road map around the candidate position. The removal detection (or tracking) server estimates the position of the removal detection package 1 to be the point where the candidate position of the removal detection package 1 extracted based on the signal arrival distance intersects with the driving route of the vehicle on which the removal detection package 1 is mounted.

When estimating the position of the removal detection package 1 based on one signal arrival time, it is possible to omit the position estimation process by the removal detection (or tracking) server. In this case, the position estimation function provided by the removal detection (or tracking) server may be provided by each AP, and written into the transmission signal including the removal information.

Note that the removal detection (or tracking) server assumes that the time used within each AP device is synchronized (time-synchronized) with each other. In the following, the removal detection (or tracking) server notifies each AP of a signal (time information) for synchronizing the time, thereby synchronizing the time of each AP. However, this is not limited to this, and any method can be used to synchronize the time of each AP with each other. For example, time synchronization can be performed by having each AP receive a GPS (Global Positioning System) signal or radio waves from a radio-controlled clock.

The accuracy of time measurement in each AP may be determined arbitrarily depending on the accuracy of the estimated position of the package 1 with removal detection function, the processing power of each AP, etc. For example, if it is desired to estimate the position on the order of Km (kilometers), the AP is designed to be able to measure time on the order of milliseconds. Alternatively, if it is desired to estimate the position on the order of M (meters), the AP is designed to be able to measure time on the order of nanoseconds. If it is difficult to measure time on the order of nanoseconds due to the processing power of each AP, the accuracy of the estimated position is reduced within an acceptable range, and each AP is allowed to measure time on the order of what it can process (for example, on the order of 100 nanoseconds).

As described above, according to this embodiment, the capacitance sensor 12 arranged in the storage area 14 into which the contents 200 of the package 11 are inserted can easily detect the presence or absence of the contents 200 in the storage area 14 based on the difference in capacitance depending on the presence or absence of the contents in the storage area 14. In addition, since it is a capacitance type, it can be detected without being affected by the color or shape of the contents 200. Furthermore, a method of detecting the presence or absence of the contents 200 by directly touching the contents 200, such as a switch type, is prone to false detection due to vibration during transportation of the package 11, but since this embodiment is a non-contact type, it is possible to suppress the occurrence of false detection due to vibration. In other words, it is possible to easily determine whether the delivered package 11 has been opened and the contents 200 (item) contained in the storage area 14 of the package 11 has been removed.
This makes it possible to reliably confirm that the contents 200 have been removed from the packaging 11 of the packaging 1 with removal detection function that has been sent, thereby improving the reliability of determining that the sent contents 200 themselves have been received at the destination, rather than just the packaging 1 with removal detection function that has been sent, compared to when opening detection is performed.

Furthermore, according to this embodiment, in response to the removal information transmitted from the removal detection package 1, each of the single or multiple APs that received the removal information supplies the removal information, to which time information has been added, via the base station to the removal detection (or tracking) server. This makes it possible to obtain the position of the removal detection package 1 together with predetermined time information, and facilitates tracking of the removal detection package 1 during delivery.
In addition, since time information is added to the removal information, it is possible to easily detect the time when the contents 200 were removed from the packaging body 11, enabling the sender to accurately obtain the time (date and time) when the contents were received at the distant destination.

In addition, according to this embodiment, the LPWA standard communication technology is used, and the removal detection device 100 is power-savingly configured to start up by supplying power to it when it is sent, so that it is possible to determine whether the contents 200 have been removed from the package 11 of the package 1 with removal detection function and to track the package 1 with removal detection function with low power consumption, and therefore it can be used when sending the contents 200 to a destination that will take a long time to arrive. Also, since an RFID reader or the like for reading conventional RFID (Radio Frequency Identification) tags is not required, there is no need to install a dedicated device at the destination.

Second Embodiment
Hereinafter, a description will be given of a package with removal detection function according to a second embodiment of the present invention with reference to the drawings. Fig. 5 is a diagram showing an example of the configuration of a package with removal detection function according to the second embodiment of the present invention. In Fig. 5, the depth direction (vertical width direction) in which the contents 200 are inserted into the package 11 of the package with removal detection function 1 is the Z direction, the thickness direction of the package 11 is the Y direction, and the width direction of the package 11 is the X direction.

Fig. 5A shows an example of the configuration of a removal detection device provided in a package with removal detection capabilities. The cross section of the package with removal detection capabilities in Fig. 5A is a cross section perpendicular to the X direction.
FIG. 5B shows an example of the cross section (cross section perpendicular to the Z direction) of the package with removal detection function.
Hereinafter, only the configuration and operation of the second embodiment that are different from the first embodiment will be described.

In FIG. 5A, the removal detection device 100A includes a starting unit 101, a data detection unit 102A, a removal detection unit 103A, an information output unit 104, a transmission unit 105, a storage unit 106, and a battery 107.
The data detection unit 102A detects whether a contact switch 12A (described later) serving as a sensor unit is in an on or off state via a signal line S1A, and outputs detection information indicating the on or off state to the removal detection unit 103A.

When the detection information indicates an on state, the removal detection unit 103A determines that the contents 200 are not present between the contact switches 12A, i.e., that the contents 200 have been removed from the storage area 14 of the package 11.
On the other hand, when the detection information indicates an off state, the removal detection unit 103A determines that the contents 200 are present between the contact switches 12A and that the contents 200 have not been removed from the storage area 14 of the package 11.

Next, a mounting structure of the contact switch 12A to the packaging body 11 will be described with reference to FIGS. 5(a) and 5(b).
A first electrode 12_1A is disposed (attached) to an inner surface 11S1 of the packaging body 11. A second electrode 12_2A is disposed on an inner surface 11S2 opposed to the inner surface 11S1 of the packaging body 11. Here, the first electrode 12_1A and the second electrode 12_2A are disposed at positions where they overlap on the inner surface 11S1 and the inner surface 11S2, respectively, in a plan view.

The contact switch 12A is composed of a first electrode 12_1A and a second electrode 12_2A arranged opposite to the first electrode 12_1A. Signal lines S1A corresponding to the first electrode 12_1A and the second electrode 12_2A are each connected to a data detection unit 102A.
In this configuration, contents 200, such as documents, papers, articles, etc., are inserted between the first electrode 12_1A and the second electrode 12_2A in the storage area 14.

When the contents 200 are present between the first electrode 12_1A and the second electrode 12_2A, the contact switch 12A is turned off because the first electrode 12_1A and the second electrode 12_2A are not in contact (short circuit).
On the other hand, when there is no content 200 between the first electrode 12_1A and the second electrode 12_2A, the first electrode 12_1A moves in the Q1 direction and the second electrode 12_2A moves in the Q2 direction, causing the first electrode 12_1A and the second electrode 12_2A to come into contact with each other, thereby turning the contact switch 12A to the on state.

Thus, by detecting whether the contact switch 12A is in the on state or the off state, it is possible to determine the presence or absence of the contents 200 between the first electrode 12_1A and the second electrode 12_2A. In other words, it is possible to determine whether the contents 200 (documents, papers, etc.) have been removed from the package 11.
An example of the operation of the process of removing the contents 200 from the package 11 in the package 1A with removal detection function in this embodiment is the same as the flowchart shown in FIG.

As described above, in this embodiment, the presence or absence of contents 200 between each of the first electrode 12_1A and the second electrode 12_2A, i.e., whether or not the contents 200 have been removed from the storage area 14 of the package 11, is detected depending on whether the contact switch 12A is in the on or off state.
The contact switch 12A may be a proximity switch equipped with a magnetic sensor and a magnetic body, and may be configured such that, for example, the magnetic sensor is disposed at the position of the first electrode 12_1A and the magnetic body is disposed at the position of the second electrode 12_2A.

In this case, when an object is inserted between the magnetic sensor and the magnetic body, the distance between the magnetic sensor and the magnetic body increases, so that the output value (e.g., voltage signal) of the magnetic sensor is smaller than when no object is inserted. On the other hand, when no object is inserted between the magnetic sensor and the magnetic body, the distance between the magnetic sensor and the magnetic body decreases, so that the output value of the magnetic sensor is larger than when an object is inserted.
Therefore, the data detection unit 102A compares the output value of the magnetic sensor with a preset value, and determines that the magnetic sensor is in the OFF state when the output value exceeds the preset value, whereas the data detection unit 102A determines that the magnetic sensor is in the ON state when the output value of the magnetic sensor is equal to or less than the preset value.

Here, the specified value can be set arbitrarily in accordance with the contents 200; for example, the contents 200 can be actually inserted between the magnetic sensor and the magnetic material, and the specified value can be set slightly higher than the output value of the proximity switch when the contents 200 are inserted.
The predetermined value is written and stored in advance in the storage unit 106 .
Then, the data detection unit 102A reads a predetermined value from the storage unit 106, and compares this predetermined value with the output value of the proximity switch to detect whether the proximity switch is in an on or off state.

When the removal detection unit 103A receives information indicating an OFF state from the data detection unit 102A, it determines that the contents 200 have not been removed from the package 11. On the other hand, when the removal detection unit 103A receives information indicating an ON state from the data detection unit 102A, it determines that the contents 200 have been removed from the package 11.

According to this embodiment, the presence or absence of the contents 200 in the storage area 14 can be easily detected depending on whether the contact switch 12A (or the proximity switch) arranged in the storage area 14 into which the contents 200 of the package 11 are inserted is in the on or off state. In addition, since a proximity switch is used, detection can be performed without being affected by the color or shape of the contents 200. Furthermore, a method of detecting the presence or absence of the contents 200 by directly contacting the contents 200, such as a switch type, is prone to false detection due to vibration during transportation of the package 11, but since this embodiment is a non-contact type, false detection due to vibration can be suppressed. In other words, it is possible to easily determine whether the delivered package 11 has been opened and the contents 200 (item) contained in the storage area 14 of the package 11 has been taken out.
As a result, as in the first embodiment, it is possible to reliably confirm that the contents 200 have been removed from the packaging 11 of the sent packaging 1A with removal detection function, and therefore, compared to the case where opening detection is performed, it is possible to improve the reliability of determining that the sent contents 200 itself has been received at the destination, rather than just the receipt of the packaging 1A with removal detection function.

Furthermore, according to this embodiment, the removal information transmitted from the packaging product with removal detection function 1A is supplied to a removal detection (or tracking) server via a base station from each of the single or multiple APs which receive the removal information, and therefore the position of the packaging product with removal detection function 1A can be obtained together with predetermined time information, facilitating tracking of the packaging product with removal detection function 1A during shipping.
In addition, since time information is added to the removal information, it is possible to easily detect the time when the contents 200 were removed from the packaging body 11, enabling the sender to accurately obtain the time (date and time) when the contents were received at the distant destination.

In addition, this embodiment uses LPWA standard communication technology and has a power-saving configuration in which power is supplied to the removal detection device 100 at the time of delivery, so that it is possible to determine whether the contents 200 have been removed from the package 11 of the package 1A with removal detection function and to track the package 1A with removal detection function with low power consumption, and therefore can be used when delivering the contents 200 to a delivery destination that will take a long time to arrive. In addition, there is no need for an RFID reader or the like to read conventional RFID (Radio Frequency Identification) tags, so there is no need to install a dedicated device at the delivery destination.

Third Embodiment
Hereinafter, a description will be given of a package with removal detection function according to a third embodiment of the present invention with reference to the drawings. Fig. 6 is a diagram showing an example of the configuration of a package with removal detection function according to the third embodiment of the present invention. In Fig. 6, the depth direction (vertical width direction) in which the contents 200 are inserted into the package 11 of the package with removal detection function 1B is the Z direction, the thickness direction of the package 11 is the Y direction, and the width direction of the package 11 is the X direction.

Fig. 6(a) shows a configuration example of a package with removal detection function 1B and a holder 10 (e.g., a translucent clear file) containing contents 200, in which a removal detection device 100B and an illuminance sensor 12B are arranged and inserted into the package with removal detection function 1B. The cross section of the package with removal detection function in Fig. 6(a) is a cross section perpendicular to the Z direction.
FIG. 6B is a plan view of the configuration example of the holder 10 as viewed from the Y direction.
FIG. 6C shows an example of the configuration of a removal detection device 100B.
Only the configuration and operation of the third embodiment that are different from the first embodiment will be described below.

FIG. 6A shows the holder 10 in which the removal detection device 100B and the illuminance sensor 12B are disposed.
The holder 10, with the contents 200 enclosed therein, is inserted into the storage area 14 of the package 11. That is, the holder 10 is delivered to the delivery destination together with the contents 200 as part of the package 1B with removal detection function.
In this configuration, the holder 10 is disposed at a position that blocks light from the illuminance sensor 12B in the storage area 14. Into the holder 10, for example, documents, paper, objects, etc. are inserted.
When removing the contents 200 from the package 11 at the delivery destination, it is necessary to first remove the holder 10 and then remove the contents 200 from the holder 10 .

By removing the holder 10 from the packaging body 11, the illuminance sensor 12B is no longer shielded from light by the packaging body 11, and the illuminance sensor 12B arranged in the holder 10 is exposed to ambient light.
The illuminance sensor 12B outputs an output value corresponding to the intensity of the ambient light to the removal detection device 100B via a signal line S1B.

As shown in FIG. 6B, the holder 10 has a removal detection device 100B and an illuminance sensor 12B arranged in an arrangement area 10S.
Here, it is desirable that the placement portion 10S is provided at a corner of the holder 10 so as not to interfere with the insertion of the contents 200.
When the holder 10 is inserted into the packaging body 11, no ambient light is incident on the illuminance sensor 12B, so the output value (e.g., a voltage signal) is smaller than when the holder 10 is not inserted into the packaging body 11. On the other hand, when the holder 10 is not inserted into the packaging body 11, ambient light is incident on the illuminance sensor 12B, so the output value is larger than when the holder 10 is inserted into the packaging body 11.

The illuminance sensor 12B may be installed either inside or outside the holder 10, but it is more preferable to install it inside the holder 10. When the holder 10 is sealed in the packaging body 11, the illuminance sensor 12B is in a state where it is shielded from light by the packaging body 11. However, depending on the material of the packaging body 11, the light shielding may not be sufficient, and the difference between when the holder 10 is inserted and when the holder 10 is removed may be small. Even in this case, removal detection is possible by setting a predetermined value (described later), but measurement errors become more severe and false detection may occur. However, by installing the illuminance sensor 12B inside the holder 10, light shielding by the holder 10 in addition to the packaging body 11 can be performed, so that the light detection difference between when the holder 10 is removed and when it is shielded can be made wider. As a result, false detection can be reduced.
The holder 10 has a degree of transparency such that the output value (e.g., voltage value) of the illuminance sensor 12B does not exceed a predetermined value (described later) when the ambient light passes through the packaging body 11. Here, the transparency of the holder 10 is appropriately set by experiment according to, for example, the material of the packaging body 11 and the thickness of the packaging.

6C, the removal detection device 100B includes a starting unit 101, a data detection unit 102B, a removal detection unit 103B, an information output unit 104, a transmission unit 105, a storage unit 106, and a battery 107.
The data detection unit 102B detects whether an illuminance sensor 12B (described later) serving as a sensor unit is in an on or off state via a signal line S1B, and outputs detection information indicating the on or off state to the removal detection unit 103B.
That is, the data detection unit 102B compares the output value of the illuminance sensor 12B with a preset value, and determines that the illuminance sensor 12B is in the ON state when the output value exceeds the preset value, whereas the data detection unit 102B determines that the illuminance sensor 12B is in the OFF state when the output value is equal to or less than the preset value.

Here, the predetermined value can be arbitrarily set in accordance with the intensity of the ambient light that passes through the packaging body 11 and enters the illuminance sensor 12B. For example, an experiment is performed in which the holder 10 is inserted into the packaging body 11 and removed from the packaging body 11, and the predetermined value is set to be slightly higher than the output value of the illuminance sensor 12B when the holder 10 is inserted into the packaging body 11.
The predetermined value is written and stored in advance in the storage unit 106 .
Then, the data detection unit 102B reads a predetermined value from the storage unit 106, and compares this predetermined value with the output value of the illuminance sensor 12B to detect whether the illuminance sensor 12B is in the ON state or the OFF state.

When off-state information is supplied from data detection unit 102B to removal detection unit 103B, it determines that holder 10 has not been removed from packaging body 11, i.e., that contents 200 have not been removed from packaging body 11.
On the other hand, when on-state information is supplied from data detection unit 102B to removal detection unit 103B, it determines that holder 10 has been removed from package 11, i.e., that contents 200 have been removed from package 11.
An example of the operation of the process of removing the content 200 from the package 11 in the package 1B with removal detection function in this embodiment is the same as the flowchart shown in FIG.

According to this embodiment, the presence or absence of the holder 10 in the storage area 14 of the package 11, i.e., the presence or absence of the contents 200, can be easily detected depending on whether the illuminance sensor 12B mounted on the holder 10 containing the contents 200 is in the on or off state. In addition, since an illuminance sensor is used, detection can be performed without being affected by the color or shape of the contents 200. Furthermore, a method of detecting the presence or absence of the contents 200 by directly contacting the contents 200, such as a switch type, is prone to false detection due to vibration during transportation of the package 11, but since this embodiment is a non-contact type, false detection due to vibration can be suppressed. In other words, it is possible to easily determine whether the delivered package 11 has been opened and the contents 200 (item) contained in the storage area 14 of the package 11 has been taken out.
As a result, similarly to the first embodiment, it is possible to reliably confirm that the contents 200 have been removed from the packaging 11 of the sent packaging 1B with removal detection function. Therefore, compared to the case where only opening detection is performed, it is possible to improve the reliability of determining that the sent contents 200 itself has been received at the destination, rather than just the receipt of the packaging 1B with removal detection function, from the sender.

Furthermore, according to this embodiment, the removal information transmitted from the removal detection package 1B is sent to the removal detection (or tracking) server via the base station from one or more APs that receive the removal information, and the removal information is sent with time information added thereto, making it possible to obtain the position of the removal detection package 1B together with predetermined time information. This makes it easy to track the removal detection package 1B during delivery.
In addition, since time information is added to the removal information, it is possible to easily detect the time when the contents 200 were removed from the packaging body 11, enabling the sender to accurately obtain the time (date and time) when the contents were received at the distant destination.

In addition, according to this embodiment, the LPWA standard communication technology is used, and the removal detection device 100 is activated by supplying power at the time of delivery, so that it is a power-saving configuration, and therefore it is possible to check whether the contents 200 have been removed from the package 11 of the package 1B with removal detection function and to track the package 1B with removal detection function with low power consumption, and it can also be used when delivering the contents 200 to a delivery destination that will take a long time to arrive. In addition, since an RFID reader or the like for reading conventional RFID (Radio Frequency Identification) tags is not required, there is no need to install a dedicated device at the delivery destination.

In this embodiment, the illuminance sensor 12B is provided inside (on the inner surface) of the holder 10, but if the packaging of the packaging body 11 can block most of the ambient light, the illuminance sensor 12B may be provided outside (on the outer surface) of the holder 10.

Fourth Embodiment
Hereinafter, a description will be given of a package with removal detection function according to a fourth embodiment of the present invention with reference to the drawings. Fig. 7 is a diagram showing an example of the configuration of a package with removal detection function according to the fourth embodiment of the present invention. In Fig. 7, the depth direction (vertical width direction) in which the contents 200 are inserted into the package 11 of the package with removal detection function 1C is the Z direction, the thickness direction of the package 11 is the Y direction, and the width direction of the package 11 is the X direction.

7A shows a configuration example of a package 11 containing contents 200, in which a package 1C with removal detection function, a removal detection device 100C and a wire break sensor 12C are disposed and inserted into the package 1C with removal detection function. The cross section of the package 1C with removal detection function in FIG. 7A is a cross section perpendicular to the Z direction.
The contents 200 are, for example, documents, paper, articles, etc., and are fixed to a fixing plate 302 by a fixing member 301 .

Since the contents 200 are fixed to the fixing plate 302 by a fixing member 301 such as cardboard or plastic wrap, in order to remove the contents 200 from the package 11, it is necessary to remove the contents 200 together with the fixing plate 302.
Between the fixing plate 302 and the packaging body 11, for example, a loop-shaped conductive wiring S1C is provided. This conductive wiring S1C is configured to be disconnected when the fixing plate 302 is removed from the packaging body 11. As an example, at least a part of the bottom of the fixing plate 302 is conductive, and a separated wiring is provided on the inner surface of the packaging body 11. Then, the fixing plate 302 is bonded and arranged at a position where the wiring on the inner surface of the packaging body 11 is conductive. As a result, the conductor at the bottom of the fixing plate 302 and the conductive wiring on the inner surface of the packaging body 11 form a loop-shaped wiring S1C. Therefore, when the fixing plate 302 is removed together with the contents 200, the conductive wiring of the packaging body 11 becomes disconnected.

FIG. 7B shows an example of the configuration of a removal detection device 100C.
In FIG. 7B, the removal detection device 100C includes a starting unit 101, a data detection unit 102C, a removal detection unit 10C, an information output unit 104, a transmission unit 105, a storage unit 106, and a battery 107.
Only the configuration and operation of the fourth embodiment that are different from the first embodiment will be described below.

The data detection unit 102C is connected to one end S1C-1 and the other end S1C-2 of the loop-shaped wiring S1C described above. The data detection unit 102C forms a disconnection sensor together with the wiring S1C. For example, the data detection unit 102C outputs a pulse signal from one end S1C-1 to the wiring S1C, and determines whether the wiring S1C is disconnected based on whether the pulse signal can be detected at the other end S1C-2.

The data detection unit 102C detects that the wiring S1C is in a conductive state when it can detect a pulse signal at the other end S1C-2, whereas the data detection unit 102C detects that the wiring S1C is in a disconnected state when it cannot detect a pulse signal at the other end S1C-2.
When the conductive wiring S1C of the packaging body 11 is in a conductive state, the disconnection sensor 12C outputs detection information indicating the conductive state to the removal detection unit 103C. On the other hand, when the conductive wiring S1C of the packaging body 11 is in a disconnected state, the disconnection sensor 12C outputs detection information S1C indicating the disconnected state to the removal detection unit 103C.

Furthermore, the data detection unit 102C may be configured to, for example, pass a current from one end S1C-1 to the wiring S1C and determine whether or not the wiring S1C is broken depending on whether or not the current can be detected at the other end S1C-2.
Here, in order to reduce power consumption, the data detection unit 102C may perform a detection process to determine whether or not the wiring S1C is in a broken state using the above-mentioned pulse signal or current at a predetermined time interval (e.g., once a day, once an hour, etc.).

When information of a conductive state is supplied from the data detection unit 102C, the removal detection unit 103C determines that the fixing plate 302 has not been removed from the packaging body 11, i.e., that the contents 200 have not been removed from the packaging body 11.
On the other hand, when information of a disconnection state is supplied from the data detection unit 102C to the removal detection unit 103C, it determines that the fixing plate 302 has been removed from the packaging body 11, i.e., that the contents 200 have been removed from the packaging body 11.
An example of the operation of the process of removing the contents 200 from the package 11 in the package 1C with removal detection function in this embodiment is the same as the flowchart shown in FIG.

According to this embodiment, the presence or absence of the fixing plate 302 in the storage area 14 of the package 11, i.e., the presence or absence of the contents 200, can be easily detected depending on whether the wiring S1C on the inner surface of the package 11 to which the fixing plate 302 to which the contents 200 are fixed is in a conductive state or a disconnected state. In addition, since a disconnection sensor consisting of the data detection unit 102C and the wiring S1C is used, detection can be performed without being affected by the color or shape of the contents 200. Furthermore, a method of detecting the presence or absence of the contents 200 by directly touching the contents 200, such as a switch type, is prone to false detection due to vibration during transportation of the package 11, but since the present embodiment is fixed to the package 11 by the fixing plate 302, the occurrence of false detection due to vibration can be suppressed. In other words, it is possible to easily determine whether the delivered package 11 has been opened and the contents 200 (item) contained in the storage area 14 of the package 11 has been taken out.
As a result, similarly to the first embodiment, it is possible to reliably confirm that the contents 200 have been removed from the packaging 11 of the sent packaging 1C with removal detection function. Therefore, compared to the case where only opening detection is performed, it is possible to improve the reliability of determining that the sent contents 200 itself has been received at the destination, rather than just the receipt of the packaging 1C with removal detection function.

Furthermore, according to this embodiment, the removal information transmitted from the removal detection package 1C is sent to a removal detection (or tracking) server via a base station from one or more APs that receive the removal information, and the removal information is sent with time information added thereto, making it possible to obtain the position of the removal detection package 1C together with predetermined time information. This makes it easy to track the removal detection package 1C during delivery.
In addition, since time information is added to the removal information, it is possible to easily detect the time when the contents 200 were removed from the packaging body 11, enabling the sender to accurately obtain the time (date and time) when the contents were received at the distant destination.

In addition, according to this embodiment, the LPWA standard communication technology is used, and the removal detection device 100 is activated by supplying power at the time of delivery, so that it is a power-saving configuration, and therefore it is possible to check whether the contents 200 have been removed from the package 11 of the package 1B with removal detection function and to track the package 1B with removal detection function with low power consumption, and it can also be used when delivering the contents 200 to a delivery destination that will take a long time to arrive. In addition, since an RFID reader or the like for reading conventional RFID (Radio Frequency Identification) tags is not required, there is no need to install a dedicated device at the delivery destination.

In addition, a program for realizing the function of determining whether the contents 200 have been removed from the package 11 of the removal detection devices 100, 100A, 100B, and 100C shown in each of Figures 1, 5, 6, and 7 in this embodiment may be recorded on a computer-readable recording medium, and the program recorded on the recording medium may be read into a computer system and executed to perform processing for detecting whether the contents 200 have been removed from the package 11. Note that the term "computer system" here includes hardware such as the OS and peripheral devices.

Furthermore, if the WWW system is used, the "computer system" also includes the home page providing environment (or display environment).
In addition, the term "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage devices such as hard disks built into computer systems.

Furthermore, "computer-readable recording medium" includes those that dynamically hold a program for a short period of time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line, and those that hold a program for a certain period of time, such as volatile memory within a computer system that serves as a server or client in such cases. The above program may also be one that realizes part of the functions described above, or it may be one that realizes the functions described above in combination with a program already recorded in the computer system, a so-called differential file.

The above describes an embodiment of the present invention in detail with reference to the drawings, but the specific configuration is not limited to this embodiment, and includes designs that do not deviate from the gist of the present invention.
