Description

The present invention relates to a product management system, a product management method, and a product management program.

In recent years, product management using information storage media is increasing. By reading the information storage medium attached to the product or the package of the product, the product can be identified and managed.

Examples of information storage media include RFID (Radio Frequency Identifier). A user can read information by scanning an RF tag having an IC (Integrated Circuit) chip storing information with a dedicated reader. With RFID, multiple RF tags can be scanned simultaneously.

Examples of information storage media include code media represented by one-dimensional codes such as bar codes and two-dimensional codes such as QR (Quick Response) codes. A user can read the code with a camera or the like to retrieve the stored information.

Techniques related to product management using storage media are disclosed in the following prior art documents.

Japanese Patent Application Laid-Open No. 2020-95529 JP 2015-168544 A Japanese Patent Application Laid-Open No. 2006-027773

However, the user may fail to read information from the information storage medium. For example, since RFID uses radio waves to transmit and receive information to and from a dedicated reader, depending on the state of radio waves and the situation of obstacles, the reader may not be able to properly receive radio waves, resulting in failure to acquire information. Sometimes.

In addition, since the code medium acquires information from the image captured by the camera, depending on the brightness of the surroundings, the shadow of other objects, and the shooting angle, an appropriate image cannot be acquired, and information acquisition fails. Sometimes.

Also, information storage media may become unreadable due to damage. For example, an IC chip in an RF tag may be damaged by heat or by being bent by pressure. Also, the code medium is damaged by dirt and rubbing.

In product management, for example, when product information cannot be read for some reason, the user can determine whether the product is in short supply, or whether the product is not in short supply but reading of information has failed. It is difficult. In such a case, the user may erroneously determine that there is a shortage of products when in fact there is no shortage of products.

Therefore, one disclosure provides a product management system, a product management method, and a product management program that detect damage to a storage medium in product management using an information storage medium and improve the accuracy of product excess/deficiency determination. do.

[First embodiment]
A first embodiment will be described.

<Configuration example of product management system 1>
FIG. 1 is a diagram showing a configuration example of a product management system 1. As shown in FIG. The product management system 1 has a management device 100 and gates 200 . The product management system 1 compares a plurality of products T1 to be managed collected at a predetermined location with a product list describing identification information (identification information element for uniquely identifying a product) of the products to be collected. It is a system for executing product management processing for determining whether or not there is an excess or deficiency, and detecting damage to the information storage media M1 to M4 attached to the product T1.

The product T1 has information storage media M1 to M4 in which identification information of each product is stored attached (attached) to the package or the product itself. Although not shown, it is assumed that an information storage medium is attached to each of the other products T1 in FIG.

The information storage media M1 to M4 are, for example, media in which two types of storage media are integrated (integrated media). In the integrated medium, for example, a code of a code medium (second information storage medium) such as a bar code or a QR code (registered trademark) is placed on the front surface (back side of the attachment surface) of the RF tag (first information storage medium). It is printed. The RF tag and code medium each store product identification information. The user can acquire the identification information of the product by reading the information from any one of the information storage media of the integrated media.

Note that the information storage media M1 to M4 do not necessarily have to be integrated. The RF tag and code medium may be attached to different locations.

The gate 200 is a gate through which the collected product T1 passes (enters or exits). The gate 200 includes cameras 210-1 to 3 (hereinafter also referred to as cameras 210) and RFID readers 220-1 to 3 (hereinafter sometimes referred to as RFID readers 220). The gate 200 connects to and communicates with the management device 100 . The gate 200 transmits image data captured by the camera 210 and product information read by the RFID reader 220 to the management device 100 .

The camera 210 is a photographing device that photographs a plurality of products T1 at predetermined positions. The camera 210 captures image data of a plurality of products T1 positioned within a predetermined range. The camera 210 photographs the product T1 from multiple directions and acquires image data of the information storage media M1 to M4 attached to the product. The camera 210, for example, always takes pictures (for example, at short time intervals such as 1 second). Further, the camera 210 may start photographing when detecting that the product T1 is positioned near the gate 200, for example, by a user's instruction or a sensor.

The RFID reader 220 reads product information from the RF tags of the information storage media M1 to M4 of the product T1 located near the gate 200. FIG. For example, if the RF tag is a passive tab, the RFID reader 220 transmits radio waves to the RF tag and waits for radio waves returned from the RF tag. The RFID reader 220 receives radio waves from the RF tag and acquires product identification information stored in the RF tag. If the RF tag is an active tab or semi-active tab that transmits radio waves using its own battery as a power source, the RFID reader 220 waits for radio waves transmitted from the RF tag, and receives radio waves transmitted from the RF tag. By receiving the information, the identification information of the product stored in the RF tag is obtained.

The management device 100 is a device that manages products, and is, for example, a computer or a server machine. The management device 100 acquires image data captured by the camera 210 and product identification information read by the RFID reader 220 from the gate 200 . In addition, the management device 100 acquires a transported product list from, for example, a device (not shown) that manages a transported product list including identification information of products to be transported.

The management device 100 reads the code medium from the acquired image data and acquires the identification information. The management device 100 compares the identification information acquired from the code medium, the identification information read by the RFID reader 220, and the identification information of the transported product management list, and determines excess or deficiency of products, damage to the information storage medium, and the like. .

The display 160 displays, for example, the result of excess/deficiency determination and the damage status of the information storage medium.

The CPU 110 performs product management processing by executing the product management program 121 . The product management process is a process for judging excess or deficiency of conveyed products and for judging breakage of information storage media.

The CPU 110 performs data acquisition processing by executing the data acquisition program 122 . The data acquisition process is, for example, a process of communicating with the gate 200 and acquiring image data captured by the camera 210 and identification information read by the RFID reader 220 . Also, the data acquisition processing device is, for example, a process of communicating with a device that manages the product list to be transferred and acquiring the product list.

Gate 200 has camera 210 and RFID reader 220 .

The camera 210 is a photographing device that photographs products under the gate 200 (near the gate). One or a plurality of cameras 210 are installed. Also, camera 210 does not necessarily have to be in contact with gate 200 . For example, the camera 210 may be installed at a position separated from the gate 200 by a predetermined distance, include the gate 200 , and may photograph the area around the gate 200 .

The RFID reader 220 is a device that receives radio waves transmitted (returned) by the RF tag of the information storage medium attached to the product, and acquires identification information stored in the RF tag. The RFID reader 220 may be of a type built into the gate 200 or of a handy type.

<Software configuration example of product management system>
FIG. 3 is a diagram showing an example of the software configuration of the product management system 1. As shown in FIG. The product management system 1 includes an imaging unit (second reading unit) 10, an RFID reading unit (first reading unit) 20, a product management unit (management unit, first reading unit, integration unit, damage determination unit, acquisition unit) 30. have

Hereinafter, the identification information read by the code reading section 31 from the image data captured by the imaging section 10 may be referred to as code identification information (second identification information).

The information integration unit 32 generates integrated identification information by integrating the identification information included in the RF identification information and the code identification information. Integrated identification information is a list of identification information included in at least one of RF identification information and code identification information, and duplicate identification information is stored as one piece of identification information.

The product excess/deficiency determination unit 33 determines whether or not there is an excess/deficiency in the products to be transported from the integrated identification information and the transported product list. The conveyed product list is a list of identification information of products to be conveyed (scheduled to be conveyed), and is obtained, for example, from a device that manages the conveyed product list in advance or when executing excess/deficiency determination processing. Hereinafter, the identification information included in the conveyed product list may be referred to as list identification information.

The information storage medium damage determination unit 34 determines whether or not the information storage medium is damaged based on the RF identification information and the code identification information.

Note that the product management unit 30, the code reading unit 31, the information integration unit 32, the product excess/deficiency determination unit 33, and the information storage medium damage determination unit 34 are executed by the CPU 110 of the management device 100, for example, by executing a loaded program.

Also, the RFID reader 20 is, for example, an RFID reader 220 . Further, the RFID reader 20 is constructed by executing a program loaded by the CPU 110 of the management apparatus 100, for example, and uses the RFID reader 220 to perform each process.

<Product management process>
Product management processing will be described. FIG. 4 is a diagram showing an example of the sequence of product management processing. The imaging unit 10 executes imaging processing S10. The photographing process S10 is a process of photographing the conveyed product near the gate 200 using the camera 210 and obtaining image data. For example, when the photographing unit 10 receives a user's trigger to start photographing (pressing of a button, ON/OFF of a switch, etc.), when detecting that a conveyed product is positioned (approaching) near the gate 200, or The photographing process S10 is executed regularly or continuously. The photographing unit 10 hands over the image data to the code reading process S12 (S11).

After obtaining the image data, the code reading unit 31 executes a code reading process S12. The code reading process S12 is a process of detecting the code medium appearing in the image data, reading the identification information stored in the detected code medium, and generating the code identification information L1 (S13). In the code reading process S12, when a plurality of code media are detected, the identification information of each of the detected code media is read. Further, the image data may be, for example, one image at a certain timing, or may be a plurality of images captured at a plurality of timings or from a plurality of angles. The code reading unit 31 hands over the code identification information L1 to the information integration processing S20 (S14). Further, the code reading unit 31 hands over the code identification information L1 to the information storage medium damage determination processing S25 (S15).

On the other hand, the RFID reading unit 20 executes RFID reading processing S16. The RFID reading process S16 is a process of transmitting radio waves from the RFID reader 220, receiving a return radio wave including identification information from the conveyed product located near the gate 200, and generating RF identification information L2 (S17). For example, when the RFID reading unit 20 receives an RF tag reading start trigger (pressing of a button, ON/OFF of a switch, etc.) by the user, it detects that the conveyed product is positioned (approaching) near the gate 200. RFID reading processing S16 is executed when the RFID tag is detected, or periodically or continuously. The RFID reader 20 hands over the RF identification information L2 to the information integration process S20 (S18). Further, the RFID reader 20 hands over the RF identification information L2 to the information storage medium breakage determination process S25 (S19).

After acquiring the code identification information L1 and the RF identification information L2 (S14, S18), the information integration unit 32 executes information integration processing S20. The information integration process S20 is a process of generating the integrated identification information L3 from the code identification information L1 and the RF identification information L2 (S21). In the information integration process S20, the information integration unit 32 integrates a list of identification information included in both or one of the code identification information L1 and the RF identification information L2 (duplicate identification information is regarded as one identification information). It is assumed that the identification information is L3.

FIG. 5 is a diagram showing examples of code identification information L1, RF identification information L2, and integrated identification information L3. FIG. 5A shows an example of code identification information L1, FIG. 5B shows an example of RF identification information L2, and FIG. 5C shows an example of integrated identification information L3.

As shown in FIGS. 5A and 5B, the code identification information L1 includes the identification information "1009" (shaded portion in FIG. 5A), but the RF identification information L2 includes the identification information "1009". does not exist. Further, the identification information "1010" (hatched portion in FIG. 5B) exists in the RF identification information L2, but the identification information "1010" does not exist in the code identification information L1.

In the information integration process S20, the information integration unit 32 stores the identification information "1001" to "1008" included in both the code identification information L1 and the RF identification information L2 as integrated identification information L3. Further, in the information integration processing S20, the information integration unit 32 stores the identification information "1009" contained only in the code identification information L1 and the identification information "1010" contained only in the RF identification information L2 as integrated identification information L3. (hatched portion in FIG. 5(C)). In information integration processing S20, the code identification information L1 including nine pieces of identification information and the RF identification information L2 including nine pieces of identification information are integrated to generate integrated identification information L3 including ten pieces of identification information.

Returning to the sequence of FIG. 4, the information integration unit 32 hands over the integrated identification information L3 to the excess/deficiency determination process S23 (S22).

When the product excess/deficiency determination unit 33 acquires the integrated identification information L3 (S22), the excess/deficiency determination process S23 is executed. The excess/deficiency determination process S23 is a process for determining whether or not there is an excess/deficiency in the conveyed products.

FIG. 6 is a diagram showing an example of a processing flowchart of the excess/deficiency determination processing S23. The product excess/deficiency determination unit 33 acquires a conveyed product list in the excess/deficiency determination process S23 (S23-1). The conveyed product list is, for example, a list of identification information of conveyed products that pass through the gate 200 and enter or leave the warehouse.

The product excess/deficiency determining unit 33 compares the identification information of the transported product list and the identification information of the integrated identification information (S23-2). If the identification information completely matches (Yes in S23-3), the product excess/deficiency determination unit 33 determines that there is no excess/deficiency in the conveyed product (S23-4), and ends the process. On the other hand, if the identification information does not completely match (No in S23-3), the product excess/deficiency determination unit 33 determines that there is an excess/deficiency in the conveyed product (S23-5), and terminates the process.

The product excess/deficiency determination result is displayed on the display 160 of the management device 100 or output to a file, for example. Also, when it is determined that there is an excess or deficiency, the administrator or the user may be notified by sound, light, or the like. The manager refers to the excess/deficiency determination result, and if there is an excess/deficiency, confirms the excess/deficiency of the product by checking the actual product, and replenishes or removes the product to eliminate the excess/deficiency of the transported product. .

In the excess/deficiency determination process S23, if the identification information of the transported product list and the integrated identification information do not completely match, it is determined that there is an excess/deficiency of the product. In this determination method, for example, if reading of both the RF tag and the code medium of a certain product fails, it is determined that the product is in short supply even if the product is actually not in short supply. However, the probability of failing to read both the RF tag and the code medium is very small compared to reading one information storage medium. Since the integrated identification information is identification information successfully read from at least one of the RF tag and the code medium, the above-described erroneous determination may occur only when reading fails from both the RF tag and the code medium. By installing two information storage media, an RF tag and a code medium, and setting a perfect match as a condition that there is no excess or deficiency in the excess or deficiency judgment processing S23, the accuracy of automatically judging the excess or deficiency of the product is improved. do.

FIG. 7 is a diagram showing examples of integrated identification information L3, conveyed product list L4, and excess/deficiency determination results. In the excess/deficiency determination process S23, the product excess/deficiency determination unit 33 compares the integrated identification information L3 and the identification information of the conveyed product list L4 (S23-2 in FIG. 6). The product excess/deficiency determination unit 33 confirms that the identification information "1001" to "1010" are present in both the conveyed product list L4 and the integrated identification information. However, since the identification information “1011” (shaded part) of the product list L4 to be conveyed does not exist in the integrated identification information L3, the product excess/shortage determination unit 33 determines that the product list L4 to be conveyed and the integrated identification information L3 do not completely match. (No in S23-3 in FIG. 6), and it is determined that there is an excess or deficiency in the conveyed products (S23-5 in FIG. 6). The product excess/deficiency determination unit 33 determines that there is a shortage of products (identification information “1011”) to be transported (stored or shipped) because the identification information that exists in the transported product list L4 does not exist in the integrated identification information L3. do.

If there is identification information that exists in the integrated identification information L3 but does not exist in the product list L4, it is determined that there is an excess or deficiency in the product. For example, it is determined that a product that should not be transported is being transported. . Also, if there is identification information that exists in the integrated identification information L3 but does not exist in the product list L4, and there is identification information that does not exist in the integrated identification information L3 but exists in the product list L4, If the integrated identification information L3 and the number of identification information in the conveyed product list L4 are the same, it is determined that there is an excess or deficiency in the products, for example, it is determined that the wrong product is to be conveyed.

Further, when it is determined that the product to be conveyed is incorrect due to excess or deficiency, it cannot be determined whether the product is inside or outside the gate 200 in the system configuration described above. However, it may take the administrator a considerable amount of time to identify where the product is. Thus, for example, by configuring the system to read only RFID tags passing through the gate 200, it is possible to easily identify the location of a product that has been determined to be transported in error.

As a configuration for reading only RFID tags passing through the gate 200, for example, a configuration for extracting only moving tag information is conceivable. The management device 100 acquires moving tag information from the tag information of the plurality of RFID tags read by the RFID reader 220, and uses the moving tag information to determine excess or deficiency. The management device 100 may acquire moving tag information from, for example, an RFID tag filtering device having a moving object detection filter installed between the gate 200 and the management device 100 . Note that this configuration is an example, and known means may be used.

Returning to the sequence of FIG. 4, when the information storage medium damage determination unit 34 acquires the RF identification information L2 and the code identification information L1 (S19, S15), it executes the information storage medium damage determination process S25. The information storage medium damage determination process S25 is a process for detecting a damaged storage medium.

FIG. 8 is a diagram showing an example of a processing flowchart of the information storage medium damage determination processing S25. The information storage medium damage determination unit 34 compares the RF identification information and the code identification information in the information storage medium damage determination process S25 (S25-1).

The information storage medium damage determination unit 34 checks whether or not there is identification information that exists in the RF identification information but does not exist in the code identification information (S25-2). If there is identification information that exists in the RF identification information but does not exist in the code identification information (Yes in S25-2), the information storage medium damage determination unit 34 determines that the code medium of the product with the corresponding identification information is damaged. It is determined that there is a possibility (S25-3).

On the other hand, when all the identification information of the RF identification information exists in the code identification information (No in S25-2), the information storage medium damage determination unit 34 determines that the code medium is not damaged (S25-4).

The information storage medium damage determination unit 34 checks whether or not there is identification information that exists in the code identification information but does not exist in the RF identification information (S25-5). If there is identification information that exists in the code identification information but does not exist in the RF identification information (Yes in S25-5), the information storage medium damage determination unit 34 determines that the RF tag of the product with the corresponding identification information is damaged. It is determined that there is a possibility (S25-6), and the process ends.

On the other hand, when all the identification information of the code identification information exists in the RF identification information (No in S25-5), the information storage medium damage determination unit 34 determines that the RF tag is not damaged (S25-7), End the process.

The result of the information storage medium damage determination process S25 is displayed on the display 160 of the management device 100 or output to a file, for example. Also, when it is determined that any of the information storage media is damaged, the administrator or the user may be notified by sound, light, or the like. The administrator checks the information storage medium of the product determined to be possibly damaged, and confirms whether or not it is really damaged. When the administrator detects a damaged information storage medium, for example, the administrator replaces the information storage medium.

In the information storage medium damage determination process S25, it is assumed that the code medium having the identification information in the RF identification information but not in the code identification information may be damaged. Further, in the information storage medium damage determination processing S25, it is assumed that an RF tag having identification information included in the code identification information but not included in the RF identification information may be damaged. In this determination method, for example, if both the RF tag and the code medium are damaged, damage to the information storage medium cannot be detected. However, in the product management system 1, the information storage medium damage determination processing S25 is executed each time the gate 200 is passed, so there is a high possibility that at least one of the media will be detected as being damaged. Further, when both information storage media are damaged, it is determined that the product is insufficient when compared with the conveyed product list in the excess/deficiency determination process S23. However, since the product actually exists, it can be determined that both information storage media have failed or failed to read, and damage can be detected.

FIG. 9 is a diagram showing an example of the RF identification information L2, the code identification information L1, and the determination result of the information storage medium damage determination processing S25. 9A and 9B are diagrams showing examples of the same RF identification information L2 and code identification information L1, respectively.

According to FIG. 9A, the identification information "1010" of the RF identification information L2 does not exist in the code identification information L1. Therefore, the information storage medium damage determination unit 34 recognizes that the code medium with the identification information "1010" could not be read, and there is a possibility that the code medium of the product corresponding to the identification information "1010" is damaged. I judge.

According to FIG. 9B, the identification information "1009" of the code identification information L1 does not exist in the RF identification information L2. Therefore, the information storage medium damage determination unit 34 recognizes that the RF tag with the identification information "1009" could not be read, and there is a possibility that the RF tag of the product corresponding to the identification information "1009" is damaged. I judge.

In the first embodiment, the management device 100 can detect the damage of the information storage medium attached to the product while managing the excess or deficiency of products passing through the gate 200 .

[Other embodiments]
The RF tag and code medium may be other information storage media. As described above, if both information storage media are damaged at the same time, it is difficult to automatically detect the damage. Therefore, it is preferable to combine information storage media that are unlikely to be damaged at the same time. That is, it is preferable to combine information storage media having different damage factors (for example, one is vulnerable to heat and the other is vulnerable to friction).

Also, more than two types of information storage media may be attached to the product. Furthermore, a plurality of the same information storage media may be attached to the product. When attaching the same information storage medium to a product, it is preferable to attach them at positions as far apart as possible in order to avoid damage at the same time. Also, when the same information storage medium is attached to a product, it is possible to detect damage by managing the number of successful readings.

Also, the RF tag and the code medium are not limited to being integrated. For example, they may be attached to different locations according to the characteristics of each information storage medium (factor of failure, size, position of reading device).

Furthermore, the code medium may be either a one-dimensional code such as a bar code or a two-dimensional code such as a QR code (registered trademark).
