Etc. may be individually attached to the container, or may be attached to a container, or a product or the like individually attached with an RFID tag may be stored in a container with an RFID tag. A container in which an RFID tag is attached to a container that stores products and the like will be described as a container.

FIG. 1 shows an explanatory diagram of an environment in which the RFID reader according to the present invention is used. 1(A) to 1(C), an RFID reader (hereinafter referred to as “aircraft”) 11 for a flying object (described in FIG. 2) is arranged in a goods warehouse 12, and the goods warehouse 12 holds shelves. 13 are arranged in, for example, three rows (held shelf rows 13A to 13C). As shown in FIG. 1B, each of the holding shelves 13 has, for example, three stages, each of which is provided with reading range marks 17A to 17C (described in FIG. 4) indicating a reading range, and each of the shelves has a reading range mark 17A to 17C. The container 15 is attached with the RFID tag 16 of the unique information and is placed on each. The unique information of each RFID tag 16 includes at least the product name, model number, and the like of the container 15, as well as address information of the position where the product is stored in the product warehouse 12.

On the other hand, the commodity warehouse 12 is provided with a station 14 which is an initial position of the aircraft 11, and is provided with electric power supply means (not shown) for charging the aircraft power source in a non-contact manner, and the surface thereof is shown in FIG. The station mark 21 shown in is formed. Note that the power supply means may be wired to charge the power source for the flight vehicle. Then, as shown in FIG. 1(C), on the floor of the goods warehouse 12, for example, a traveling direction mark 18 and flight performance marks 19 and 20 as flight-related marks along a flight route for automatic flight are provided. Are provided (described in detail in FIG. 3).

Therefore, FIG. 2 shows a configuration explanatory view of the RFID reader according to the present invention. In FIG. 2(A), the aircraft 11 is in the initial position when it is landing on the station 14 on which the station mark 21 is formed, and at this time, the aircraft power source (46 in FIG. 2(B)) is turned on. For example, it is charged from the power supply means in a contactless manner.

As shown in FIG. 2B, the flying body 11 includes a controller 41 that is a control unit, a drive mechanism unit 42, an image pickup unit 43 that is an image pickup unit, a reader 44 that is a tag reading unit, a transmission/reception unit 45, and a flying unit. A power supply 46 is provided, and the aircraft power supply 46 is provided with a charging unit 46A for charging from the power supply means of the station 14.

The drive mechanism section 42 is a mechanism including a motor for flying. The image capturing unit 43 is a camera that captures the flight-related marks, such as the station mark 21, the traveling direction mark 18, the flight marks 19, 20 and the reading range marks 17A to 17C, which are provided in the goods warehouse 12. The reader 44 reads tag information in a non-contact manner with respect to the RFID tag 16 attached to the container 15, and is generally known for RFID tags.

Upon completion of reading the RFID tag 16, the transmission/reception unit 45 causes the management device (personal computer 32, mobile terminal 33) shown in FIG. 2A to communicate with the tag via the communication relay unit 31 such as Wi-Fi (registered trademark). Send information. The management device (personal computer 32, mobile terminal 33) includes management tag data. The management tag data includes tag information (item name, model number, address information, etc.) of the RFID tags 16 of all contained objects 15 that should exist in the goods warehouse 12, and is transmitted from the air vehicle 11. By referring to the received tag information and the management tag data, the matching tag information is specified as existing in the product warehouse 12, the unmatched tag information is specified as the read-out tag information, and the RFID to be read is specified. It is calculated by the ratio of the number of tags 16 to the number of pieces of tag information that match the management tag data in the read tag information.

The controller 41 generally recognizes at least the traveling direction mark 18 and the flight marks 19, 20 (the station mark 21 when returning to the station 14) imaged by the image capturing unit 43 and causes the image to be captured by the image capturing unit 43. The read range marks 17A to 17C are recognized, and the tag information of the RFID tag 16 attached to the container 15 within the read range is read by the reader 44. The control unit 51, the storage unit 52, and the flight setting unit 53. An image analysis unit 54, a read information processing unit 55, a drive control unit 56, and a power supply monitoring unit 57.

The control unit 51 controls the flying body 11 in a centralized manner. The storage unit 52 is a memory that stores an area for executing a program and tag information data. The flight setting unit 53 is configured to make a flight of the flying body 11, and the setting content will be described with reference to FIG.

In addition, the power supply capacity condition 53A and the reading rate condition 53B are set in the flight setting unit 53. The power supply capacity condition 53A is set, for example, as a threshold that allows the power supply capacity of the aircraft power supply 46 to make at least one round in the area. The reading rate condition 53B is calculated by the ratio of the number of RFID tags 16 to be read in the reading information processing unit 55, which will be described later, to the number of tag information items that match the management tag data 16A in the read tag information, For example, it is set as 95%.

It should be noted that the flight setting unit 53 may be set with a reading time condition for flight (for example, a time zone from midnight to 6:00). Specifically, the reading time is set such that the orbiting within the area and the charging of the power supply 46 for the flying body are repeated within the time range. In this embodiment, it is assumed that the reading time condition is set. Note that a single day or a plurality of days may be set as the start date for flying the flying body 11 and reading the RFID tag 16.

The image analysis unit 54 analyzes and recognizes the traveling direction mark 18, the flight marks 19, 20 and the station mark 21 imaged by the imaging unit 43, and flight control is performed with the content set by the flight setting unit 53. (See FIG. 4A). The image analysis unit 54 recognizes the reading range marks 17A to 17C picked up by the image pickup unit 43, and is used to specify the reading position (range) by the reader 44.

The read information processing unit 55 acquires the tag information of the RFID tag 16 read by the reader 44 and stores it in the storage unit 52. After the reading is completed, the transmission/reception unit 65 causes the management device (personal computer 32, portable terminal 33) to read the information. The RFID tag 16 is read again when it is transmitted and the information of the RFID tag of the read rate or the missed reading is received from the management device.

The drive control unit 56 controls the flight of the flying body 11 by the drive mechanism 42 according to the setting of the flight setting unit 53. Then, the power supply monitoring unit 57 monitors the capacity of the power supply 46 for the flying object, and falls below a predetermined threshold value (for example, the readable power capacity of the RFID tag 16 for one round in the product warehouse 12). The flight setting unit 53 is sometimes controlled to return to the station 14.

Next, FIG. 3 shows an explanatory diagram of automatic flight in an area where the RFID reader of FIG. 2 is used, and FIG. 4 shows an explanatory diagram of setting contents regarding flight of the RFID reader of FIG. In FIG. 3, as shown in FIG. 1A, a traveling direction mark 18 and flight performance marks 19, 20 are provided in the product warehouse 12 as flight-related marks on the flight route of the flying body 11.

A check mark is displayed overlaid on the traveling direction mark 18. The traveling direction mark 18 has, for example, a triangular shape, and its vertex direction is shown as the traveling direction. From the station 14 at the initial position of the air vehicle 11, all the holding shelves 13 (holding shelves 13A in the product warehouse 12). ~ 13C) is arranged.

That is, the relationship between the traveling direction mark 18 (check mark) and the flight is set in the flight setting unit 53 of the air vehicle 11, and as shown in FIG. The traveling direction is related, and for example, “S” is read as a check mark, “1 to (number)” is a flight order, “E” is read, and “R” is repeated. Here, the check mark “R” is a base point for repeated flight, and the determination of whether or not to repeat flight is determined based on whether or not the read-out tag information of the read information processing unit 55 is present. (Described in FIGS. 6 and 7). The check marks “S” and “R” may be integrated into one form, which is effective in the case of a small area (commodity warehouse), for example.

The flight marks 19 and 20 provided in the product warehouse 12 are displayed in colors, for example. That is, in the flight setting unit 53 of the air vehicle 11, if the image recognition of the color display of the flight property mark 19 continues until the reading end “E”, it is set as forward flight, and the color display of the flight property mark 20 performs image recognition. If so, it is set as a backward flight to extract the concept of the traveling direction.

Further, reading range marks 17A to 17C (FIG. 1B) are set in the flight setting section 53 of the flying body 11 as the reading range of the RFID tag 16, and the flying height is controlled by this recognition. Is. It should be noted that symbols or symbols such as numbers may be arranged in the reading range marks 17A to 17C. For example, by arranging a number (for example, “30”) as the reading distance and by image recognition of the number, the RFID tag 16 is read by approaching the recognized number of the number (for example, 30 Cm from the shelf). It can be done.

Therefore, FIG. 5 shows an operation flowchart of the movement of the flying object that constitutes the RFID reading system of FIG. 2, and FIG. 6 shows an operation flowchart of the reading process of FIG. In FIG. 5A, it is assumed that the aircraft 11 is sufficiently charged by the power supply means on the station 14 in the goods warehouse 12 from the power supply means 46 via the charging unit 46A. The flight starts when the time (time) set by the power supply capacity condition 53A of the flight setting unit 53 arrives.

That is, when the flying object 11 flies and image-recognizes the check mark “S” of the traveling direction mark 18, the first reading range mark 17A is image-recognized and the RFID tag 16 attached to the container 15 is recognized. Reading is started (step (S)1).

After that, the traveling direction mark 18 (check mark), the reading range marks 17A to 17C, and the flying marks 19 and 20 are imaged by the imaging unit 43, and the image analysis unit 54 recognizes the image to fly and the RFID tag 16 in the reading range. Is read, the read tag information is stored in the storage unit 52 (S2), and the operation is continued until the check mark “R” shown in FIG. 3 is image-recognized (S3). When the image of the check mark “R” is recognized, it means that the flight route within the commodity warehouse 12 has been completed, and the process of whether or not to read the RFID tag 16 is repeated (FIG. 6). Or, shift to FIG. 7).

Subsequently, in FIG. 6, when the flying object 11 recognizes the check mark “R” (S3), the read information processing unit 55 communicates all the tag information stored in the storage unit 52 from the transmission/reception unit 45. It is transmitted to the management device (personal computer 32, mobile terminal 33) via the relay unit 31 (S11). The management device compares the RFID tag to be read with the tag information received from the flying object 11 based on the management tag data to calculate the reading rate, and determines whether or not the RFID tag 16 that is missed is read. The read rate and the information of the RFID tag 16 of the missed reading are collated and transmitted to the air vehicle 11.

The flying body 11 receives the reading rate and the information of the RFID tag 16 which is not read from the management device within a predetermined time (S12), and is within the reading time of the set reading time condition (S13). If the power capacity of the aircraft power supply 46 is equal to or greater than the threshold value (S14) and the calculated read rate is less than the threshold value of the read rate condition (S15), the check mark "R" shown in FIG. From the position “” to the start position “S” again, and the RFID tag 16 is read by the air vehicle 11 repeatedly from S1 in FIG. Done.

On the other hand, when the reading rate and the information of the RFID tag 16 of the missed reading is not received from the management device within the predetermined time (S12), the station mark 21 is image-recognized and returned to the station 14 (S16). Further, when the reading time condition of S13 is reached, or when the power capacity of the aircraft power supply 46 of S14 is less than the threshold value of the power capacity condition 53A, or the reading rate of S15 is greater than or equal to the threshold value of the reading rate condition. In the case of, the station mark 21 is image-recognized and returned to the station 14 (S16). That is, when the reading time condition is reached, and when the reading rate condition is reached, the reading is completed and the station returns to the station 14, and when the power supply capacity decreases, the station returns to the station 14 for charging.

In the management device (personal computer 32, mobile terminal 33), all the tag information read by the flying object 11 and the tag information read by the flying object 11 can be displayed to the administrator. As a result, when the tag information includes missed tag information, it is possible to prompt personal confirmation and human supplement reading, and it is necessary to read all RFID tags 16 manually. Compared with the case of performing the above, it is sufficient to read only the RFID tag 16 that was missed, and even if there is the RFID tag 16 that was missed, it can be said that the efficiency is improved as a whole.

On the other hand, in S14, in the case of returning to the station 14 due to the power supply capacity of the aircraft power supply 46 falling below the threshold value of the power supply capacity condition (S16), the reading time condition is not reached (S13). Waiting until the power capacity of the aircraft power supply 46 becomes equal to or higher than a threshold value or a predetermined capacity or higher (S14), and under the condition that the reading rate condition is lower than the threshold value (S15), the traveling direction mark shown in FIG. The flight is performed again at the start position of the check mark "S" of 18 and the RFID tag 16 is repeatedly read by the flying body 11 from S1 of FIG. 5 and repeated.

Next, FIG. 7 shows another operation flowchart of the reading process of FIG. In FIG. 6, when the reading rate is less than the reading rate condition, reading is repeated for all the RFID tags 16, but in FIG. 7, the RFID tags 16 that have been missed are read from the management tag data 16A. It is assumed that the address information is obtained and only the RFID tag 16 that has been missed is read again. From these, for example, in FIG. 7, it is effective when the housed position of the housed body 15 is known in advance, and in FIG. 6, the existence of the housed body 15 is known. Can be said to be effective when the accommodation position is unknown (random arrangement).

In FIG. 7A, when the flying object 11 recognizes the check mark “R” (S3), the read information processing unit 55 causes the transmission/reception unit 45 to execute the management device (personal computer) via the communication relay unit 31. 32, mobile terminal 33) (S21). The management device compares the RFID tag to be read with the tag information received from the flying body 11 based on the management tag data to calculate the reading rate, and whether the RFID tag 16 that is missed is present or not. The read rate and the information of the RFID tag 16 of the missed reading are collated and transmitted to the air vehicle 11.

The flying body 11 receives the reading rate and the information of the RFID tag 16 that is not read from the management device within a predetermined time (S22), and it is within the reading time of the set reading time condition (S23). If the power capacity of the aircraft power supply 46 is equal to or greater than the threshold value (S24) and the read rate calculated at that time is less than the threshold value of the read rate condition (S25), the process proceeds to FIG. 7B.

On the other hand, if the information of the RFID tag 16 of the read rate and the missed reading is not received from the management device within the predetermined time (S22), the station mark 21 is image-recognized and returned to the station 14 (S26). Further, when the reading time condition of S23 is reached, or when the power capacity of the aircraft power supply 46 of S24 is less than the threshold value of the power capacity condition 53A, or the reading rate of S25 is equal to or more than the threshold value of the reading rate condition. In the case of, the station mark 21 is image-recognized and returned to the station 14 (S26). That is, when the reading time condition is reached, and when the reading rate condition is reached, the reading is completed and the station returns to the station 14, and when the power supply capacity decreases, the station returns to the station 14 for charging.

In the management device (personal computer 32, mobile terminal 33), all the tag information read by the flying object 11 and the tag information read by the flying object 11 can be displayed to the administrator. With this, similarly to the above, when the tag information sent to the management device includes the missed tag information, it is possible to prompt a personal confirmation or a human supplement reading. Compared with the case where all RFID tags 16 are read manually, it is sufficient to read only the RFID tags 16 that have been missed, and even if there are RFID tags 16 that were missed, the entire RFID tag 16 is generally read. It can be said that the efficiency is improved.

On the other hand, in S24, in the case of returning to the station 14 due to the power capacity of the aircraft power source 46 falling below the threshold value of the power capacity condition (S26), the reading time condition is not reached (S23). Then, it waits until the power capacity of the aircraft power supply 46 becomes equal to or higher than the threshold value or equal to or higher than a predetermined capacity (S24), and under the condition that it is lower than the threshold value of the reading rate condition (S25), the process proceeds to FIG. 7B.

In FIG. 7B, in the range of the reading time condition and the power supply capacity condition in FIG. 7A, when the reading rate condition is less than the threshold value (S24, S25), the reading rate and the received management tag data are collated. According to the read address information of the missed tag information, the flight direction mark 18 (check mark), the reading range marks 17A to 17C, and the flying marks 19 and 20 are recognized while flying to the corresponding address position. The RFID tag 16 of the to-be-accommodated body 15 is read, the tag information matched with the management tag data 16A is stored in the storage unit 52, and the read tag information is managed by the management device (personal computer 32, mobile terminal 33). (S31). Then, in the flying object 11, it is within the reading time of the set reading time condition (S23), and the power source monitoring unit 57 determines that the power source capacity of the flying object power source 46 is not less than the threshold value (S24). Under the condition that the read rate is less than the threshold value of the read rate condition, the tag information of the missed reading is read based on the address information.

As described above, the reading efficiency (reading rate) under limited conditions does not require human operation for reading the RFID tags 16 attached to the entire contained objects 15 housed in the product warehouse 12. Can be improved. Also, when the read rate is calculated by comparing the read tag information with the management tag data, the matching tag information and the mismatched missed tag information are received, and only the RFID tag missed in the next round is read. The reading time can be shortened and the reading rate can be improved by making the reading.

In the above-described embodiment, at least the reading rate is calculated by the management device side. However, the RFID tag 16 for calculating the reading rate or the missed reading is specified by providing the flying object 11 with management tag data. Then, it may be transmitted to the management device. By the way, in the said embodiment, although the case where the flying object 11 was made to read the RFID tag 16 in the goods warehouse 12 was shown, by making a flight route share and making a plurality of machines read the RFID tag 16, It is possible to further reduce the time.

INDUSTRIAL APPLICABILITY The RFID reader of the present invention can be used in industries such as manufacture, use, and sale of a device for automatically reading an object to be stored, such as a product to which an RFID is attached, in an unmanned environment such as a warehouse.
