Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a number checking method for confirming the number of contents sealed in a container and the contents themselves.
[0002]
[Prior art]
Postal mail such as registered mail and parcel mail is sealed in a container such as a bag and delivered to reach the post office in the delivery area. Each post office opened the container every time it arrived and manually checked the contents to prevent it from being lost.
[0003]
On the other hand, there is known one that automatically confirms the delivery destination of a container sealed with mail. That is, an RFID (Radio Frequency Identification) tag is affixed to a mail piece, a handling article tracking management symbol number code is stored in this RFID tag, and the code is read from the RFID tag of each mail piece after sealing the mail piece in a container. Is read wirelessly, based on the read result, a delivery certificate and tag with RFID writing function are created, the delivery certificate is put in the container and the tag is attached to the outside of the container, and the tag code is read RFID reader And the code of the handling article in the container is read by another RFID reader unit. (For example, refer to Patent Document 1).
[0004]
[Patent Document 1]
JP-A-11-175621 (paragraphs “0150” to “0162” etc.)
[0005]
[Problems to be solved by the invention]
When the container was opened and the contents were examined manually, there was a problem that it took a long time to work and there was a problem that efficiency was low and a lot of labor was required.
Further, in Patent Document 1, after being sealed in a container, a code is read wirelessly from an RFID tag of each postal item, and a delivery certificate with an RFID writing function and a tag are created based on the read result.
[0006]
On the other hand, when the RFID communication method is used, there is a possibility that reflection or interference at the time of communication occurs due to the influence of interference between antennas, and RFID data cannot be received correctly. When such a situation occurs due to the overlap of the mail items in the container or other reasons, the actual mail items contained in the container and the mail items to be confirmed from the information of the code read from the RFID tag No longer match.
[0007]
However, since the document of Patent Document 1 creates a delivery certificate and tag with an RFID writing function based on a code read from an RFID tag, it uses the read data as it is to create a delivery certificate and tag. As a result, there was a problem that a mismatch could not be detected.
[0008]
Therefore, the present invention is capable of confirming the contents in the container without opening the container, and is capable of reliably detecting any abnormality in the data read from the contents in the container. Provide an inspection method.
[0009]
[Means for Solving the Problems]
The present invention Rutotomoni attaching the RFID tag is written at least ID as an RFID data, for example to the contents of such mailpiece and prints the bar code indicating the data having the same contents as RFID data into the contents. Then, the contents are accommodated and sealed in a plurality of containers such as bags. Further, data is read from a bar code printed on each content stored in the container, and a tag having the read data written together is attached to the container. Then, the RFID data reading section to read from the RFID tag of each content accommodated in tag information reading unit and the container reads the data that was written to the tag by a contact or non-contact RFID data wirelessly provided, tag information The data read by the reading unit and the RFID data read by the RFID data reading unit are collated to confirm the number of contents and the contents themselves.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. This embodiment will be described taking mail delivery as an example.
[0011]
(First embodiment)
As shown in FIG. 1, for example, a plurality of contents, for example, a plurality of pieces of mail 3 are attached and sealed in a container 1 such as a bag and a RFID tag 2 on which information identifying itself is written as RFID data. Yes. The information for identifying itself includes the type of mail and the destination in addition to the ID.
[0012]
Each postal item 3 is pre-printed with a bar code (not shown) indicating the same data as the RFID data together with the RFID tag 2, and the bar code is stored when each postal item 3 is accommodated in the container 1. A bar code printed on the mail piece 3 is read by a reader. When all the mail items 3 accommodated in the same container are read, the read barcode data are collected and stored in a storage medium or recorded on a recording medium.
[0013]
It should be noted that data reading of each mail piece 3 for collecting the data of the mail pieces 3 accommodated in the same container can be performed by methods other than bar code input as long as data such as a bar code can be obtained accurately.
The storage medium includes a contact type or non-contact type IC card and an RFID tag, and the recording medium includes a bar code or a two-dimensional code printed.
[0014]
A storage medium in which the barcode data read in this way is stored together or a recorded recording medium is attached to the container 1 as a tag 4. Here, for example, a non-contact type IC card that performs wireless communication using an RFID communication method is used as the tag 4.
[0015]
The container 1 to which the tag 4 is attached in this way is delivered to, for example, a relay post office. At that time, the postal matter 3 accommodated in the container 1 is confirmed. The confirmation is performed by the control terminal 6 by wireless communication using the RFID communication method for the mail piece 3 in the container 1 using the wireless antenna 5 constituting the RFID data reading unit. The tag 4 attached to the container 1 is wirelessly communicated by an RFID communication system by a handy type wireless reader 7 constituting a tag information reading unit.
[0016]
That is, the control terminal 6 constitutes a counter-counting means, and as shown in FIG. 2, first, in S1, the radio antenna 5 is controlled and attached to each mail piece 3 in the container 1. RFID data is read from the RFID tag 2 wirelessly. Subsequently, in S2, the data read from the tag 4 by the wireless reader 7 is read.
[0017]
In S3, the RFID data from the RFID tag 2 and the data read from the tag 4 are collated. In this case, the number of pieces of mail 3 and the contents of the pieces 3 are collated. In other words, the number of inspections and checking of the inspection are performed.
[0018]
There is no possibility that mails are lost on the way or other mails are mixed, and when the RFID data is correctly read from the RFID tag 2 of each mail item 3, the RFID data from the RFID tag 2 The number and content of the data read from the tag 4 are the same.
[0019]
When they match in this way, it is determined that the postal matter 3 contained in the container 1 is correct without opening the container 1. As a result, the confirmation operation can be automated, and the operation time can be shortened and the operation efficiency can be improved.
[0020]
In addition, the radio antenna 5 may receive RFID data due to the loss of postal items on the way, mixing with other postal items with RFID tags attached, or the postal items in the container overlapping or other reasons. When a situation occurs in which the mail cannot be received correctly, it is determined in the collation that the number of the mail pieces 3 is different or the contents are different even if the numbers are the same.
[0021]
Note that the situation in which the wireless antenna 5 cannot receive the RFID data correctly due to the overlap of the mail items in the container or other reasons is restored so that it can be correctly received if the state of the mail item 3 in the container 1 changes. Sometimes, it is necessary to shake the container 1 once.
[0022]
Then, when it is finally confirmed that the number of the mail pieces 3 is different or the contents are different even if the numbers are the same, it is determined as abnormal. At this time, the mail piece 3 accommodated by opening the container 1 is manually examined. Thereby, the abnormality of the mail in a container can be detected reliably.
[0023]
In this embodiment, the control terminal 6 has been described that collates the RFID data from the RFID tag 2 with the data read from the tag 4. However, the control terminal 6 has a collation function in the wireless reader 7 to The reader 7 may directly take in the RFID data from the wireless antenna 5 and collate the data read from the tag 4. In this way, the control terminal 6 can be dispensed with and the configuration is simplified.
[0024]
(Second Embodiment)
In addition, the same code | symbol is attached | subjected to the part same as embodiment mentioned above, and detailed description is abbreviate | omitted.
[0025]
As shown in FIG. 3, a database 8 is connected to the control terminal 6. In the database 8, information on the postal matter 3 accommodated in the container 1 is sent from the shipping source via a line or the like and stored in advance.
[0026]
Further, the barcode printed on each postal item 3 is a barcode of only ID. Accordingly, the packing tag 4 stores information that summarizes the IDs of the mail items 3 accommodated in the container 1.
[0027]
In such a configuration, the wireless reader 7 reads information that summarizes the ID of the postal matter 3 from the tag 4. The control terminal 6 receives information that summarizes the IDs of the mail items 3 from the wireless reader 7, and receives the contents of each mail item 3, for example, information such as type and destination, from the database 8.
[0028]
Then, using this information, the wireless antenna 5 collates with the RFID data read from the RFID tag 2 of each mail item 3.
Thus, even if collation is performed using the database 8, the same effects as those of the above-described embodiment can be obtained.
[0029]
In each of the above-described embodiments, a non-contact type IC card that performs wireless communication using the RFID communication method is used as a tag, and information is read from the tag by wireless communication using the RFID communication method as a tag information reading unit. Although a non-contact method using a wireless reader is used, the invention is not necessarily limited to this, and a contact method may be used.
[0030]
In the case of the contact method, for example, a tag is composed of a recording medium printed with a bar code or a two-dimensional code or a contact IC card, and a reader / writer that reads information by contacting the tag is used.
[0031]
【The invention's effect】
As described above in detail, according to the present invention, the contents in the container can be confirmed without opening the container, and if there is an abnormality in the data read from the contents in the container, it is ensured. Can be detected.
