Description

  The present invention relates to a book checking apparatus, a book checking method, and a program for a book storage management system that stores books in a container and manages the books by carrying the container into a library.

  In large libraries with a large amount of books, closed libraries with high book storage efficiency are often adopted. An automatic loading / unloading system has been introduced in order to improve the efficiency of taking out and returning books to the closed library.

  The automatic loading / unloading system takes out the book requested for lending from the library and transports it to the counter, receives the lending registration for the retrieved book, deletes the lending registration for the returned book, and returns the returned book. The process of returning the storage to the library and recording the storage position is automated. With this automatic loading / unloading system, it is possible to accurately and quickly execute the work of taking out and returning books to the closed library.

  In the automatic loading / unloading system, in order to easily manage a large number of books to be stored, a bar code or an RFID tag is attached to each book as a book identification medium. Each book is accommodated in a container for each of a plurality of books, and is stored in or released from the library in units of containers.

  When taking out or lending a book is requested, a container that accommodates the requested book is automatically delivered from the library and transported to the station. The librarian takes out the requested book from the container transported to the station, reads the barcode or RFID tag attached to the book, and gives the requested book to the user.

  When the return of the book is requested, the container that should accommodate the return book requested to be returned is automatically delivered from the bookcase and transported to the station. The librarian reads the barcode label or RFID tag attached to the return book, accommodates the return book in the container transported to the station, and puts the container into the library.

Japanese Patent No. 2851237 Japanese Patent No. 3290423

  In the library, books are regularly inspected (usually called collection check) as a regular work.

  When the book identification medium is an RFID tag, the identification data of the book stored in the container can be read with the book still in the container. However, when the book identification medium is a bar code, in the conventional book check, it is necessary to carry out the container, take out the books contained in the container one by one, and read the bar code attached to the book. In addition, the labor of the inspection work is extremely large, and the work time becomes enormous.

  If the book identification medium is a bar code and a book to be stored in one container is stored in another container, the more books in the library are, the more difficult it is to find the book that has been misplaced. In some cases, books that are mishandled may be substantially lost.

  For example, taking out the books stored in each container one by one, reading the barcode of the book, and checking the database data, the automatic scale storage of 500,000 books and 25,000 containers In the case of using the system, even if it is checked in 2 minutes whether or not the books are correctly stored in each container, a total of 2 minutes × 25000 containers = 50000 minutes≈830 until the inspection is completed for all containers. It takes time, inspection time and labor are large, and the accuracy of the inspection is likely to hinder the operation of the library.

  Therefore, the library side strongly requested the development of a simple and efficient book inspection method for the automatic loading / unloading system using barcodes.

  If the library is small, it is also possible to change the book identification medium attached to the book from a barcode to an RFID tag. However, in a medium or large-scale library with hundreds of thousands of books, changing the book identification medium from barcode to RFID tag requires cost and a lot of time and is used repeatedly. The use of RFID tags for library books is still under development, and its introduction has been difficult.

  The present invention has been made in view of the circumstances as described above, and is a book inspection apparatus and book inspection method for a book storage management system that can check whether a book is erroneously stored in a container at low cost and low labor. And to provide a program.

  The book inspection apparatus of the book storage management system according to the embodiment includes a reading unit, a storage unit, a first counting unit, a second counting unit, and a processing unit. The reading unit reads the container identification data attached to the container conveyed to the library. The storage means associates and stores the container identification data with the book identification data indicating the books accommodated in the container, and manages the entry and withdrawal of the books to and from the library. The first counting means acquires a first book number that is the number of books accommodated in the container based on the observation result of the books accommodated in the container. The second counting unit obtains a second number of books that is the number of books of the container managed by the storage unit. When the first book number and the second book number do not match, the processing unit stores the inspection data indicating the mismatch in the storage unit in association with the container identification data.

  In an aspect of the present invention, it is possible to provide a book inspection apparatus, a book inspection method, and a program for a book storage management system that can check whether a book is erroneously stored in a container at low cost and low labor. .

  Hereinafter, each embodiment will be described with reference to the drawings. In the following description, the same or substantially the same functions and components are denoted by the same reference numerals, and will be described as necessary.

(First embodiment)
In the present embodiment, when the number of books stored in the container acquired based on the observation result (including the observation result) does not match the number of books in the container managed in the database, this is indicated. A book inspection apparatus of a book storage management system that stores and determines containers that do not match the number of books as targets for further detailed inspection will be described.

  First, the outline of this embodiment will be described.

  For example, in a facility for storing and managing a large amount of books such as a library, a book storage management system (automatic entry / exit system) has rapidly spread. As an example, the conventional book storage management system collectively stores a plurality of books in each container, and manages the loading and unloading of the books using a barcode attached to each book.

  In the library, books are checked every few years as regular work. As this book check, a method has been implemented in which a book is individually checked by reading a barcode attached to the book, and a difference between the book stock managed by the book storage management system and the actual stock is found. . As described above, the book inspection method of taking out each book and reading the barcode is more difficult to implement as the number of books increases, the work effort and work time increase.

  The book inspection apparatus, the book inspection method, and the program according to the present embodiment are based on a new idea that has never existed in the past from the viewpoint of solving the problems of book inspection as described above, and the book storage Check books in the management system at low cost and with low labor, and improve work efficiency.

  That is, in the conventional book check, the book is individually checked by reading the barcode of each book, whereas in the present embodiment, the total number of books in the container is accommodated in the container. It is detected whether or not the number of books acquired based on the observation results of the book and the number of books counted based on the database are inconsistent, and only the mismatched containers in this extremely narrow range are checked. And The inspection of individual books for the mismatched containers can easily identify the book name by using, for example, the inspection using the image of Japanese Patent No. 3290423.

  In the present embodiment, it is considered that the number of containers determined to be inconsistent between the number of books based on the observation result and the number of books managed in the database is extremely smaller than the number of containers determined to be in agreement. In other words, for the following reasons (a) and (b), it is possible to efficiently perform book inspection work at low cost and low labor by excluding containers judged to be coincident from the object of detailed inspection. it can.

  (a) Containers that are judged to be in agreement are those in which no books have been received or delivered during the period of the book check, or have been processed normally.

(b) A case where the number of books based on the observation results of the books contained in the container and the number of books based on the database is judged to be the same, but the books are not stored correctly is the book of a container. Occurs when the same number of books are exchanged with books in other containers. This case is considered statistically. In a book storage management system with a collection of 500,000 books and a scale of 25,000 containers, assuming that one book error that does not depend on the regular method occurs with a probability of 1/1000, one book happens to come from another container. The probability of entering is (1/1000) ^2, which is a negligible range. Furthermore, the probability that the number of books will match as a result of n books being replaced is (1/1000) ^{2 × n,} which is not discussed. Therefore, when the number of books of the container acquired based on the observation result matches the number of books of the container based on the database, it may be determined that there is no mistake. In addition, it can be obtained from the operation results of the book storage management system so far that the probability of occurrence of a shipping error is about 1/1000.

  Here, an example of the basic configuration of the book inspection apparatus 100 according to the present embodiment will be described with reference to FIG.

  In the book inspection apparatus 100 according to the present embodiment, the information processing apparatus 6 receives container identification data D1 for identifying the container 12 from the reading apparatus 102.

  In addition, the information processing apparatus 6 receives the number of books acquired based on the observation result of the books stored in the container 12 from the first count unit 103.

  Further, the information processing apparatus 6 reads and executes the program 105 stored in the storage medium 104, thereby functioning as the second count unit 106, the processing unit 107, and the correction unit 108.

  The information processing apparatus 6 can write and read various data with reference to the database 2.

  The reading device 102 reads the container identification data D1 attached to the container 12. For example, a barcode or a two-dimensional code is used as the container identification data.

  The first count unit 103 acquires the number of books accommodated in the container 12 based on the observation result, and transmits it to the information processing apparatus 6. For example, the first counting unit 103 includes a video display device that displays video data captured by the imaging device, and an input device that receives the number of books stored in the container 12 from an inspector who has observed the video data. It is good. For example, the first count unit 103 may include a detection device that automatically detects the number of books accommodated in the container 12 by optical, electrical, or other methods. The detection device may be, for example, a laser displacement meter that measures the distance to a book accommodated in the container 12, or a video analysis device that analyzes the video of the container 12, and includes a photographing device that captures video data of the container 12. It is good.

  The database 2 stores the container identification data D1 in association with the book identification data D3 indicating the books 32 accommodated in the container 12, and manages the entry and withdrawal of the books to and from the library.

  Further, the database 2 indicates that the container characteristic data D12 used for determining whether or not the container 12 belongs to the inspection candidate is inconsistent with the container identification data D1, and the number of books of the container 12 is inconsistent, so that the container 12 has a more detailed inspection. When the target is determined, the correction data D6 for specifying the book of the cause of the mismatch in the container 12 is stored in association with each other. When the first counting unit 103 includes a photographing device, the database 2 may store the video data of the book 32 stored in the container 12 photographed by the photographing device in association with the container identification data D1. . When the first counting unit 103 includes a laser displacement meter, the database 2 may store the measurement data measured by the laser displacement meter in association with the container identification data D1. Further, the database 2 is based on the container identification data D1 based on various data (synthesized video data, synthesized video data) generated by the video analysis device when the first counting unit 103 includes the video analysis device. The number of books detected in this manner may be stored in association with each other.

  The container feature data D12 includes, for example, history data indicating a history of book entry and book delivery for the container 12.

  The second counting unit 106 uses the book 12 of the container 12 managed in the database 2 based on the container identification data D1 stored in the database 2 and the book identification data D3 associated with the container identification data D1. Get the number.

  When the number of books acquired by the first count unit 103 and the number of books acquired by the second count unit 106 do not match, the processing unit 107 has caused a mismatch in the container 12 and the container 12 Is stored in the database 2 in association with the container identification data D1.

  Here, when the processing unit 107 indicates that the container 12 does not belong to an inspection candidate based on the container feature data D12, the processing unit 107 determines the container 12 as a non-inspection target. For example, when the container feature data D12 includes history data, the processing unit 107 removes the container 12 based on the history data when neither the book entry nor the book delivery for the container 12 occurs during the inspection target period. Decided to be inspected.

  When the processing unit 107 determines that the number of books in the container 12 does not match, the correction unit 108 inputs correction data D6 that identifies the book causing the mismatch in the container 12 based on the correction operation. The correction data D6 is associated with the container identification data D1 and stored in the database 2.

  FIG. 2 is a flowchart showing an example of processing of the book inspection apparatus 100 according to the present embodiment.

  In step S1, the reading device 102 reads the container identification data D1 attached to the container 12 conveyed to the library.

  In step S2, the database 2 stores the book identification data D3 indicating the books accommodated in the container 12 in association with the container identification data D1, and manages the receipt of the books to and the delivery of the books.

  In step S <b> 3 </ b> A, the first count unit 103 acquires the number of books accommodated in the container 12 based on the observation result of the books 32 accommodated in the container 12.

  In step S <b> 3 </ b> B, the second count unit 106 acquires the number of books of the container 12 managed in the database 2.

  In step S <b> 4, the processing unit 107 determines whether the number of books acquired by the first count unit 103 and the number of books acquired by the second count unit 106 do not match.

  In the case of mismatch, in step S5A, the processing unit 107 stores the inspection data D5 indicating the mismatch in the database 2 in association with the container identification data D1, and determines the container 12 as a more detailed inspection target.

  In the case of coincidence, in step S5B, the processing unit 107 excludes the container 12 from more detailed inspection.

  The effect of the book inspection apparatus 100 of the book storage management system having the above configuration will be described.

  The book inspection apparatus 100 according to the present embodiment is greatly different from a system that stores and manages book information by reading a barcode used in, for example, a bookstore. That is, the book checking apparatus 100 according to the present embodiment uses only a container having a difference between the number of books in the actual inventory based on the observation result and the number of books managed in the database 2, for example, in more detail according to Japanese Patent No. 3290423. The containers to be inspected, the number of containers to be inspected can be narrowed down to a very small number, and books that cause inconsistencies can be found efficiently at low cost and low labor.

(Second Embodiment)
In the present embodiment, a video display device that displays the video of the container 12 containing the books 32, an input device that receives a visual input of the number of books (number of books) contained in the container in which the video is displayed, A book storage management system including an information processing device 6 that generates inspection data D5 indicating a comparison result between the number of books input from the input device and the number of books managed as being stored in the container 12 in the database 2 The book management apparatus 100 will be described.

  In the present embodiment, for example, a barcode is used as identification data readable from the outside, but other identification data may be read.

  FIG. 3 is a block diagram showing an example of the configuration of the book inspection apparatus 100 of the book storage management system 1 according to this embodiment.

  In the present embodiment, the container 12 is divided into two blocks in the conveyor width direction F2 perpendicular to the traveling direction F1 of the transport conveyor 28.

Furthermore, the barcode 12c is attached to the container 12 so as to face the outside in the conveyor width direction F2.

  In the present embodiment, the case where the photographing device 3a and the barcode reader 36b of the book storage management system 1 are installed on one side of the conveyor 28 in the conveyor width direction F2 will be described as an example. Another imaging device and another barcode reader may be installed on the other side in the direction F2, and the book storage management system 1 may execute the same processing.

  When the imaging device 3a and the barcode reader 36b are installed only on one side in the conveyor width direction F2 as in the present embodiment, the container is provided with a rotation mechanism that reverses the orientation of the container 12. It is possible to check whether books are properly accommodated for both 12 blocks.

  A book storage management system 1 and a book inspection apparatus 100 applied to the book storage management system 1 include a database 2, a container position detector 36 a, a barcode reader 36 b, an imaging device 3 a, and an information processing device 6. The terminal TRa includes a video display device 4a and an input device 5a. The terminal TRb includes an output device 4b and an input device 5b.

  In FIG. 3, a barcode 12c corresponds to the container identification data D1 in FIG. The barcode reader 36b corresponds to the reading device 102 in FIG. The imaging device 3 a and the terminal TRa correspond to the first count unit 103.

  The container position detector 36a, the barcode reader 36b, and the imaging device 3a of the book storage management system 1 are installed in the imaging unit 36 in the path of the transfer conveyor 28 for transferring the container 12 returned to the book shelf.

  In the present embodiment, the library accommodates a plurality of containers 12. Each container 12 can accommodate a plurality of books. The books are accommodated in the container 12 with the spine facing outward in the conveyor width direction F2. Each book has a barcode.

  The database 2 stores and manages container identification data D1, video data D2, book identification data D3, container accommodation position data D4, inspection data D5, correction data D6, container operating time data D7, inspection history data D8 and the like in association with each other. . The container accommodation position data D4, the container operation time data D7, and the inspection history data D8 correspond to the container feature data D12 in FIG.

  The container identification data D1 represents the container 12.

  The video data D2 is data obtained by photographing all the books stored in the container 12 from the back cover side.

  The book identification data D3 represents a book stored in the container 12. When a plurality of books are accommodated in the container 12, a plurality of book identification data D3 is associated with the container identification data D1.

  The container accommodation position data D4 represents a position where the container 12 is accommodated in the library.

  The inspection data D5 includes a combination of the number of books of the container 12 managed in the database 2 and the number of books of the container 12 input by visual recognition of the video data D2, and whether or not the container 12 is a subject of more detailed inspection. This data is used for the determination of

  The correction data D6 is data that identifies the book that is the cause of the mismatch. For example, the correction data D6 designates a missing book or a book that should not be accommodated in the container 12 when there is a mismatch in the number of books in the inspection data D5.

  The container operating time data D7 represents time data when the container 12 is transported, and represents, for example, the container operating time.

  The inspection history data D8 represents inspection time data (for example, confirmation date) and the number of inspections.

  The container identification data D1 and the book identification data D3 are read based on the barcode 12c attached to the container 12 and the barcode attached to the book at the time of entering and leaving the book. By accessing the data stored in the database 2, it is possible to grasp which books are stored in which containers, how many books are stored in which containers, and the like.

  The container position detector 36a detects that the container 12 transported by the transport conveyor 28 has reached the imaging position.

  The barcode reader 36b is an example of a device that reads identification data, and automatically reads and reads the barcode 12c attached to the side surface of the container 12 in a state where the container 12 is detected by the container position detector 36a. The container identification data D1 corresponding to the barcode is sent to the information processing device 6.

  The imaging device 3a is installed on one side of the conveyor 28. The imaging device 3a captures all the books contained in one row of the container 12 from the back cover side in a state where the container 12 is detected by the container position detector 36a, and records the captured video data D2 as information. Send to processing device 6. As the photographing apparatus 3a, for example, a digital camera, a digital still camera, a digital video camera, or the like can be applied. The imaging device 3a only needs to be able to capture and output digital video data using an electrical signal. For example, a plurality of imaging devices 3a are installed, a plurality of video data D2 are captured, a plurality of video data D2 are stored in association with one container identification data D1, and a plurality of video data D2 are checked. May be used.

  The imaging device 3a outputs information of an optical image (still image or moving image) of the captured subject to the information processing device 6 as video data D2. The video data D2 is digital video data, for example. The video data D2 output from the imaging device 3a is stored in the database 2 for video storage in association with the container identification data D1, after the amount of data is reduced by a predetermined video compression process.

  The information processing device 6 receives the container identification data D1 from the barcode reader 36b, receives the video data D2 from the imaging device 3a, and stores the container identification data D1 and the video data D2 in association with each other in the database 2.

  The information processing device 6 refers to the database 2, obtains the number of books in the container 12 managed in the database 2 based on the number of book identification data D 3 associated with the container identification data D 1, and manages it in the database 2. The inspection data D5 including the number of books of the container 12 being stored is stored in the database 2.

  When the container 12 is inspected, the information processing device 6 reads the video data D2 and inspection data D5 associated with the container identification data D1 indicating the container 12 from the database 2, and sends them to the video display device 4a.

  In step T4, the central processing unit 37 drives the barcode reader 36b and reads the barcode of the container 12.

  In step T5, the central processing unit 37 performs photographing with the photographing device 3a.

  In step T6, the central processing unit 37 determines whether the reading of the barcode 12c of the container 12 and the photographing by the photographing device 3a are correctly performed.

  When it is determined that the barcode reading and the book photographing are correctly performed, in step T7A, the central processing unit 37 determines the container identification data D1 corresponding to the barcode of the container 12 read by the barcode reader 36b, and the photographing device. The video data D2 photographed in 3a is stored in the database 2 in association with each other. Note that the video data D2 may be compressed and stored in the database 2.

  If it is determined that the barcode reading and book photographing have not been performed correctly, in step T7B, the central processing unit 37 has not correctly performed the reading of the barcode 12c of the container 12 and the photographing by the photographing device 3a. Information indicating this is stored in the database 2, and the information is displayed on the operation display unit 34.

  In step T <b> 8, the central processing unit 37 outputs a conveyor start signal for starting the transport conveyor 28 to the overall control panel 50 to drive the transport conveyor 28.

  The central processing unit 37 stores the video data D2 corresponding to the designated container 12 in the database 2 based on the operation of the operation display unit 34 by a librarian, an inspector 8a, an inspection manager 8b, a user, or the like. The video data D2 is also displayed on the operation display unit 34.

  According to the present embodiment, in the path of the transport conveyor 28 for transporting the containers 12 returned to the bookshelf group 11, the spine covers 32a, 32a,. The books 32, 32,... Contained in two rows are photographed from the back cover 32a, 32a,. The captured video data D2 is stored in the database 2 in association with the container identification data D1. The video data D2 stored in the database 2 is arbitrarily read and displayed as a video. Thereby, the accommodation state of the books 32, 32,... In each container 12, 12,.

  Each container 12, 12. When it becomes necessary to check the accommodation status of the books 32, 32,... Accommodated in..., The librarian, the inspector 8a, the inspection manager 8b, and the user actually remove the container 12 from the bookshelf group 11. Without taking out to the first floor or second floor stations 20 and 22, the necessary container 12 is specified, the video data D 2 is read from the database 2, displayed, and the books 32, 32,... You can easily see the situation. This makes it possible to improve the efficiency of managing the books 32, 32,.

  For example, in the free-location-type book storage management system 1, when returning the book 32, a librarian reads the barcode attached to the book 32, and the central processing unit 37 corresponds to the read barcode. The book identification data and the container identification data corresponding to the barcode of the container 12 that accommodates the book 32 need to be associated with each other and stored in the hard disks 45 and 47 and the like.

  However, in practice, the librarian did not read the barcode of the book 32 by mistake, or the barcode could not be read accurately due to damage to the barcode of the book 32 or a malfunction of the barcode reader 35. The book 32 may be accommodated in the container 12 and stored in the library.

  In such a case, in order to search for the books 32 that have been erroneously returned, the dates and times at which the books 32 were issued and received in the past are sequentially tracked, and each container 12 used at that time is checked. It is necessary to visually check the inside of the. In the case of performing this confirmation work, conventionally, for example, each container 12 to be confirmed is sequentially taken out to the first floor or second floor stations 20 and 22, and the librarian confirms it. It takes a long time.

  However, in this embodiment, the inspector 8a can visually check the accommodation state of the books 32, 32,... In each container 12, 12,. The number of books in the container 12 counted at least once by at least one inspector 8a is compared with the number of books in the container 12 managed in the database 2.

  FIG. 20 is a screen diagram illustrating a first example of a book inspection screen displayed on the inspection terminal TRa.

  The book inspection screen displayed by the terminal TRa is managed by the display unit of the video data D2, the display unit of the book identification data stored in the container 12 to be checked managed by the database 2, and the database 2. The number of books in the container 12 is included.

  The inspector 8a operates the terminal TRa and inputs the number of books of the container 12 confirmed by the video data D2 while switching the entire video data D2, the video enlarged on the left side, and the video enlarged on the right side.

  The information processing device 6 stores in the database 2 inspection data D5 indicating the result of comparing the number of books from the terminal TRa with the number of books that are stored in the container 12 to be checked in the database 2.

  FIG. 21 is a screen diagram showing a second example of the book inspection screen. In FIG. 21, the book check screen includes an input area 80a for the number of books in the container 12 counted by the checker 8a, and displays the number of books 80b in the container 12 managed in the database 2. .

  In the present embodiment described above, it is possible to efficiently and accurately confirm a book that has been mixed into the container 12 or a book that has been forgotten to be stored in the container 12, and an increase in inspection cost can be suppressed.

  There is a very small probability that the receipt of illegal books and the delivery of illegal books overlap in the same container 12, and the container 12 includes illegal books, but the number of books in the container 12 does not change. Therefore, in the present embodiment, paying attention to the number of books in the container 12, and so that there is no mistake in counting, at least one inspector 8a can count the number of books in the container 12 one or more times. Thus, the validity of the book 32 accommodated in the container 12 is determined. The book inspection apparatus 100 and the book inspection method according to the present embodiment are introduced into the book storage management system 1 by comparing and considering the inspection accuracy and the inspection labor when checking a large number of books.

  In the present embodiment, the left side of the video data D2 of the container 12 can be enlarged or the right side can be enlarged. Even if a thin book 32 or the like is accommodated in the container 12, the thin book 32 The spine can be displayed clearly, and it is possible to prevent erroneous counting.

  In this embodiment, it is possible to easily check the accommodation state of the books 32, 32,... In the container 12 without actually taking out the container 12 from the library to the first floor or the second floor stations 20, 22. Therefore, the management efficiency of the books 32, 32,... Can be further improved.

  In the present embodiment, it is possible to perform a book check without obstructing normal library operations.

  It should be noted that making the accommodation state of the books 32, 32,... In each container 12, 12,. This is effective not only when it occurs, but generally when it is desired to look inside the container 12 in the course of tracking the book 32 in order to search for the missing book 32.

  The video data D2 is used not only by the librarian for the inspection work by the inspector 8a and the search for the lost book 32, but also as an auxiliary system for searching the target book 32 by a general user. Good. In the above description, the container 12 is specified, and the video data D2 corresponding to the container 12 is read from the database 2 and displayed. However, the container 12 and the books 32 and 32 accommodated in the container 12 are described. ,... Are stored in association with each other. Therefore, by designating the book 32, the video of the container 12 accommodated in the book 32 can be displayed.

  The video data D2 obtained by photographing with the photographing device 3a is stored in the database 2 with a reduced data amount by, for example, compression processing. In this case, the database 2 does not have to have a large storage capacity, and data can be easily rewritten. Further, necessary data can be read from the database 2 when necessary, and the inspector 8a and the inspection manager 8b can perform video display, display screen printout, and the like.

  In the present embodiment, based on the correction data D6, it is possible to efficiently correct the mismatch in the relationship between the container 12 and the books accommodated in the container 12.

  For example, when the number of books accommodated in the container 12 managed in the database 2 is larger than the number of books confirmed by visual inspection by the inspector 8a, it should be accommodated in the container 12 but is contained in the container 12. Correction data D6 indicating that the goods are being delivered can be attached to the missing book identification data D3, so that it can be easily confirmed which books are missing in the container 12.

  For example, when the number of books accommodated in the container 12 managed in the database 2 is less than the number of books confirmed by the visual inspection of the inspector 8a, the extra book can be extracted by calling the container 12.

(Third embodiment)
This embodiment demonstrates the case where the 1st count part 103 of the book inspection apparatus 100 which concerns on the said 1st Embodiment contains the detection apparatus which detects the number of books automatically. In this embodiment, the case where the detection device is a laser displacement meter will be described as an example. However, for example, a video analysis device that analyzes video data D2 and counts the number of books accommodated in the container 12 is used. Other devices may be used.

  FIG. 22 is a block diagram illustrating an example of a book checking apparatus including a laser displacement meter 81.

  The laser displacement meter 81 measures, for example, the distance to the upper part of a book accommodated in the container 12 or the spine. The laser displacement meter 81 and the book in the container 12 perform measurement while relatively moving. For example, the book storage management system moves the container 12 at a predetermined speed in the container traveling direction, and the laser displacement meter 81 measures the time series data 82 of the distance between the laser displacement meter 81 and the book 32 in the container 12. To do. The time series data 82 may be stored in the database 2 in association with the container identification data D1.

  The information processing apparatus 6 detects a change in distance based on the time series data 82 and obtains the number of books in the container 12.

  The information processing apparatus 6 determines whether or not the number of books in the container 12 in the database 2 matches the number of books obtained by the laser displacement meter 81.

  When it is determined that the number of books of the container 12 in the database 2 and the number of books obtained by the laser displacement meter 81 do not match, the book storage management system checks the container 12 with an inspector 8a using the terminal TRa. Or a detailed inspection by the inspection manager 8b using the terminal TRb.

  Thereby, the number of containers to be inspected by the inspector 8a or the detailed inspection by the inspection manager 8b can be reduced, and the inspection work of the library can be made more efficient.

  Note that when the number of books in a container is counted by a plurality of methods, the order in which the comparison is performed can be appropriately determined. For example, when the number of books obtained by the laser displacement meter 81 or the video analysis device does not match the number of books managed by the database 2, the number of books obtained by the terminal TRa is managed by the database 2. It may be determined whether or not they match. Conversely, when the number of books obtained by the terminal TRa does not match the number of books managed in the database 2, the number of books obtained by the laser displacement meter 81 or the video analyzer is managed in the database 2. It may be determined whether or not the number of books is different.

  Further, for example, the number of books obtained by the laser displacement meter 81 or the video analyzer, the number of books obtained by the terminal TRa, and the number of books managed in the database 2 are simultaneously compared to detect a mismatch. May be.

  FIG. 23 is a block diagram showing a schematic configuration of a book inspection apparatus of the book storage management system according to the present embodiment.

  The database 2 stores the inspection data D5, inspection history data D8, work classification data D9, container operation time data D7, station identification data D10, and worker identification data D11 in association with the container identification data D1.

  The inspection history data D8, work classification data D9, container operation time data D7, station identification data D10, and worker identification data D11 according to the present embodiment correspond to the container feature data D12 in FIG.

  The work classification data D9 indicates whether a book entry work or a book delivery work has been performed on the container 12.

  The container operation time data D7 indicates the time when the container 12 is taken out to the station for the book entry work or the book delivery work.

  The station identification data D10 indicates the station that has left the container 12.

  The worker identification data D11 indicates a worker who has performed a book entry operation or a book delivery operation for the container 12.

  When the inspection data D5, inspection history data D8, work classification data D9, container operation time data D7, station identification data D10, and worker identification data D11 do not satisfy the conditions as inspection candidates, the information processing apparatus 6 Is determined as a non-inspection target.

  Specifically, the information processing apparatus 6 can switch the inspection candidates among the uninspected container, the inspected container, and all the containers based on the inspection data D5 or the inspection history data 8.

  The information processing device 6 can switch the inspection candidates between the container that has performed the book delivery operation, the container that has performed the book entry operation, and all the containers based on the work classification data D9 or the container operation time data D7.

  Based on the container operation time data D7, the information processing apparatus 6 can determine inspection candidates according to the time when the container is taken out to the station.

  Based on the station identification data D10, the information processing apparatus 6 can determine which station the container has taken out as an inspection candidate.

  Based on the worker identification data D11, the information processing device 6 can determine inspection candidates based on workers such as a librarian who has performed loading / unloading work and a librarian who has performed book loading work.

  As described above, in this embodiment, the inspection candidate containers are narrowed down based on the inspection data D5, the inspection history data D8, the work classification data D9, the container operation time data D7, the station identification data D10, and the worker identification data D11. be able to. As a result, the number of inspection candidate containers can be reduced, and more efficient and quick archive inspection can be performed.

(Fifth embodiment)
In the present embodiment, a modification of the second embodiment will be described.

  In the second embodiment, the inspector 8a inputs the number of books. Instead of this, the inspector 8a uses the container to be inspected managed by the database 2 displayed on the book inspection screen. A comparison result as to whether or not the number of books within 12 matches the number of books counted by the user may be input. In this case, the information processing apparatus 6 receives the container identification data D1 and the comparison result input by the inspector 8a from the terminal TRa, generates inspection data D5 indicating whether or not the number of books matches, and generates container identification data D1. And the inspection data D5 are stored in the database 2 in association with each other.

  FIG. 24 is a system configuration diagram showing an example of a book inspection device of the book storage management system according to the present embodiment.

  In FIG. 24, the server 83 corresponds to the information processing apparatus 6 of FIG. The book inspection apparatus is configured by connecting a server 83 and a plurality of inspection terminals TR1 to TRN via a hub 84. Terminals TR1 to TRN include, for example, a web application. The plurality of terminals TR <b> 1 to TRN send the number of books counted by the inspector to the server 83.

  Based on the number of books received from the plurality of terminals TR1 to TRN, the server 83 generates inspection data D5 indicating whether or not the books accommodated in the container 12 to be inspected are valid.

  In each of the above-described embodiments, the case where the book storage management system accommodates the books 32, 32,...

(Sixth embodiment)
The present embodiment is a modification of the above embodiments. The book inspection apparatus according to the present embodiment shoots a plurality of video data from the front direction of the back cover of the book 32 accommodated in the container 12, and generates front image data of the container 12 based on the plurality of video data ( And the number of books in the container 12 is obtained based on the generated front image data.

  FIG. 25 is a block diagram illustrating an example of a book inspection apparatus of the book storage management system according to the present embodiment.

  The book checking device 100 a includes a reading device 102, a photographing device 3 a, an information processing device 6, and a database 2.

  The information processing apparatus 6 reads and executes the program 105a stored in the storage medium 104, thereby executing the container identification unit 109, the video data storage unit 110, the synthesis unit 111, the first count unit 103a, and the second count. Functions as a unit 106, a processing unit 107, and a correction unit 108.

  The reading device 102 reads the container identification data D1 of the container 12 and sends the container identification data D1 to the information processing device 6. As the reading device 102, for example, a bar code reader 36b is used.

  The imaging device 3 a is installed, for example, on one side of the conveyor 28 so as to face the spine of the book 32 stored in the container 12.

  The imaging device 3a detects the container 12 being transported by the transport conveyor 28 from when the container 12 is detected by the container position detector 36a until the container 12 is detected by the container position detector 36c. Shoot continuously from the front.

  Then, the imaging device 3a sends a plurality of video data D131 to D13n of the container 12 captured continuously or at a predetermined interval to the information processing device 6.

  The container identification unit 109 receives container identification data D1 attached to the container 12 read by the reading device 102. The container identification unit 109 stores the container identification data D1 in the database 2.

  The container identification unit 109 identifies the barcode 12c attached to the container 12 based on the video data D131 to D13n obtained by the photographing apparatus 3a or the front image data D14 synthesized by the synthesis unit 111. Then, the container identification data D1 corresponding to the container 12 may be obtained. In this case, the reading device 102 can be omitted.

  The video data storage unit 110 receives a plurality of video data D131 to D13n of the container 12 from the photographing apparatus 3a, and stores the video data D131 to D13n and the container identification data D1 in the database 2 in association with each other.

  The combining unit 111 combines the front image data D14 of the container 12 based on the video data D131 to D13n stored in the database 2, associates the front image data D14 and the container identification data D1, and stores them in the database 2. . For example, the combining unit 111 connects a series of video data D131 to D13n and combines the front image data D14 of the container 12. More specifically, the synthesizer 111 selects data in a range corresponding to the front of the photographing device 3a from the photographed video data D131 to D13n, and joins the selected data to obtain the container 12's data. The front image data D14 is synthesized.

  Based on the front image data D14 stored in the database 2, the first count unit 103a performs image processing such as edge extraction, corner extraction, line extraction, and the like, and the number of books stored in the container 12 Is detected. Then, the first count unit 103a sends the number of detected books to the processing unit 107. The first count unit 103a may store the container identification data D1 and the number of books detected in the database 2 in association with each other.

  As described above, the second count unit 106 is managed in the database 2 based on the container identification data D1 stored in the database 2 and the book identification data D3 associated with the container identification data D1. The number of books in the container 12 is acquired. Then, the second count unit 106 sends the number of books in the container 12 managed in the database 2 to the processing unit 107.

  As described above, when the number of books received from the first count unit 103a and the number of books received from the second count unit 106 do not match, the processing unit 107 has caused a mismatch in the container 12. Inspection data D5 indicating that the container 12 is to be subjected to more detailed inspection is stored in the database 2 in association with the container identification data D1.

  In the present embodiment, the photographing apparatus 3a may be an area camera or a line camera, for example. The line camera includes optical sensors arranged linearly (one-dimensional) and outputs linear (one-dimensional) video data. For example, the line camera is arranged so that the observation direction of the optical sensor faces the direction of the spine of the book 32. A series of linear video data D131 to D13n photographed continuously or at predetermined intervals while transporting the container 12 by the line camera is developed into a planar (two-dimensional) front image data D14 by the synthesis unit 111 ( Converted).

  In the present embodiment, the area camera and the line camera may be used together or may be switchable.

  FIG. 26 is a flowchart illustrating an example of processing of the book inspection apparatus 100a according to the present embodiment.

  In step S <b> 201, the reading device 102 reads the container identification data D <b> 1 attached to the container 12. The container identification unit 109 stores the container identification data D1 in the database 2.

  In step S202, the container position detector 36a determines whether or not the container 12 transported by the transport conveyor 28 has entered the photographing range A1 of the photographing device 3a.

  If the container 12 is not within the shooting range A1, step S202 is repeated.

  When the container 12 enters the shooting range A1, the shooting device 3a outputs video data D131 in step S203.

  In step S204, the video data storage unit 110 stores the video data D131 and the container identification data D1 in association with each other in the database 2.

  In step S205, the container position detector 36c determines whether or not the container 12 has exited from the imaging range A1 of the imaging device 3a.

  If the container 12 is not out of the shooting range A1, the process returns to step S203. Thereby, while the container 12 moves, for example, in the photographing range A1, photographing by the photographing device 3a is repeated, and the video data storage unit 110 can store the video data D131 to D13n in the database 2.

  When the container 12 leaves the shooting range A1, in step S206, the composition unit 111 selects data corresponding to the shooting range A2 in front of the shooting device 3a from the video data D131 to D13n. The synthesizer 111 synthesizes the front image data D14 indicating the front of the container 12 based on the data corresponding to the imaging range A2 of the video data D131 to D13n. The information processing apparatus 6 stores the front image data D14 and the container identification data D1 in association with each other in the database 2.

  For example, the container identification data D1 may be generated based on at least one of the video data D131 to D13n or the front image data D14, and the above step S201 may be deleted.

  In step S207A, the first counting unit 103a detects the number of books accommodated in the container 12 based on the front image data D14. The first count unit 103a may store the container identification data D1 and the number of books detected based on the front image data D14 in the database 2 in association with each other.

  In step S <b> 3 </ b> B, the second count unit 106 acquires the number of books of the container 12 managed in the database 2.

  The subsequent steps S4, S5A, and S5B are as described above.

  In the present embodiment described above, the number of books accommodated in the container 12 can be automatically detected with high accuracy based on the video data D131 to D13n photographed by the photographing device 3a. In the present embodiment, the moving container 12 is photographed by the photographing device 3a. Therefore, the book check can be executed at low cost, with low labor, at high speed and with high accuracy.

  FIG. 27 is a diagram showing a display example of the front image data D14 according to the present embodiment.

  The front image data D14 represents a state in which the back cover of the book 32 accommodated in the container 12 is photographed from the front.

  On the other hand, FIG. 28 is a diagram showing a display example of video data taken once by an area camera with the same container 12 stopped as a comparative example.

  As shown in FIG. 28, when the container 12 is photographed once, the back cover of the book 32 accommodated near the center of the container 12 is photographed in a state facing the photographing device 3a. The spine of the book 32 accommodated at both ends is taken from an oblique direction. As shown in FIG. 28, for example, when large and small books 32 are mixed in the container 12, a small book may be hidden by a large book, and the exact number of books may not be counted.

  When the applicant has tested the book using the video data shown in FIG. 28, the number of the books 32 in the container 12 that is not accurately counted is about 3% of all the containers 12, for example. there were. For example, when the number of containers to be inspected is 10,000, re-inspection is required for 300 containers. Assuming that an inspection time of 2 minutes per container is required, the time required for reinspection is 2 minutes / container × 300 containers = 600 minutes = 10 hours.

  On the other hand, as shown in FIG. 27, when the book check is performed based on the front image data D14 according to the present embodiment, the container 12 does not depend on the position of the book 32 accommodated in the container 12. The back cover of the book 32 inside can be taken from the front. The books with arrows in FIG. 27 are difficult to detect in FIG. 28, but can be detected in FIG.

  Thus, in this embodiment, the number of books accommodated in the container 12 can be accurately counted. Therefore, in the present embodiment, the number of containers 12 that require reinspection can be reduced, and the inspection time can be greatly reduced. Moreover, in this embodiment, since it can image | photograph, conveying the container 12, without stopping the conveyance conveyor 28 for imaging | photography, the work time of a book check can be reduced.

  Furthermore, when the line camera is used in the present embodiment, the video resolution can be further increased as compared with the case where the area camera is used. For example, comparing a 5 million pixel area camera with 2448 pixels in the horizontal direction and 2050 pixels in the vertical direction with a line camera with 7500 pixels, the number of pixels in the vertical direction of the line camera is three times the number of pixels in the vertical direction of the area camera. That's it. Therefore, when the line camera is used, clearer video data can be obtained than when the area camera is used, and the number of books 32 in the container 12 can be counted with high accuracy.

  In the present embodiment, the video data storage unit 110, the synthesis unit 111, and the first count unit 103a may be provided in a video analysis device different from the information processing device 6.

  The front image data D14 is not used only for counting the number of books. For example, the identification of the container identification data D1, the correction data D6 (FIG. 7) in the second embodiment, and the warehousing book confirmation screen (FIG. 13). The book check screen (FIGS. 20 and 21) may be applied. Further, the display content of the front image data D14 may be referred to by the inspector 8a or the inspection manager 8b and used to input the number of books. The whole or part of the front image data D14 can be enlarged and displayed, and the display part of the front image data D14 can be changed. Thereby, the oversight of the inspector 8a and the inspection manager 8b can be prevented.

  FIG. 29 is a diagram illustrating an example of the installation positions of the barcode reader 36b used as the reading device 102 and the photographing device 3a.

  The container 12 is disposed on the carriage 113 from the depositing / dispensing station 112 via the vertical transfer machine 64 and the container loading port 27. When the container 12 is installed on the cart 113, the barcode of the container 12 is read by the barcode reader 36b. The container 12 and the carriage 113 are moved by the transfer conveyor 28. The imaging device 3a is installed in the filling rate measurement area. The traveling speed of the carriage in the photographing range A1 is low. In the present embodiment, the container 12 is photographed by the photographing device 3a while moving the carriage 113 on which the container 12 is mounted. In this way, by shooting while moving the container 12, the portion of the video data D131 to D13n that captures the container 12 from the front can be synthesized. Further, in the present embodiment, the number of books can be counted with high accuracy by a single photographing device 3a, the increase in the number of photographing devices 3a is prevented, and the manufacturing cost of the book inspection device 100a is suppressed. Can do.

  The above embodiments can be combined as appropriate, and can be changed within the scope of the technical idea.

  Further, the above-described constituent elements can be appropriately combined or divided. For example, the terminals TRa and TRb may be the same terminal. The database 2 may be divided into a plurality of storage devices. The inspector 8a and the inspection manager 8b may be the same. The operations of the terminals TRa and TRb and the information processing apparatus 6 may be changed. The function of the information processing device 6 may be realized by cooperation of a plurality of information processing devices.
