Description

  The present invention relates to a system for grasping work in a physical distribution warehouse, and in particular, work subdivided based on position information between a worker terminal and a conveyance car terminal, ID information of a pallet containing a product, and image data obtained by photographing the inside of the physical distribution warehouse. Related to the operation in the distribution warehouse to grasp the

  There are various operations in the distribution warehouse from product receipt to shipment, and in some large-scale distribution warehouses, tag information attached to the product is read, stored, taken out, sorting, etc. are automated and most of the workers are involved Although automated warehouses and the like that do not need to be realized are realized, in the small or medium-sized logistics warehouses, most of the work is mainly performed by handling by workers.

  In the warehouse, there are many tasks involving picking and de-banning of products to be shipped, such as moving in the warehouse, and it is not easy to grasp the tasks such as where the workers are engaged in which tasks and which products are handled. For example, even a worker whose work area is determined and who is determined to perform the specified work within the area may be called for the support of another area to perform a temporary support work. It usually happens. It is more difficult to grasp such temporary work.

When handling the products of multiple shippers in the warehouse, it is desirable to calculate the cost based on the work time and work content required for handling the products of each shipper, and to calculate the physical distribution costs for each shipper, but as mentioned above At present, the accuracy of costing does not improve very much because it is difficult to grasp such tasks.
Therefore, methods for simplifying the performance management and work analysis of workers have been studied.

In Patent Document 1, an ID is set for each event such as work content (case pickup, inspection, loading, etc.) or shipment, and printed in the form of a bar code, and the operator carries out the event to carry out the ID to a portable terminal A task management system is disclosed that associates the information with the read time, and further calculates and manages the time difference between different event data.
Compared with the case of selecting and inputting the work content by traversing the hierarchy from the menu screen of the portable terminal, since it is only necessary to read the ID corresponding to the work directly, various work can be performed although the time and effort of the input can be saved. It is necessary for the worker who performs the job to select and read the ID every time the work is switched, and the burden of such incidental work is large.

In addition, although the required time for the ID can be calculated from the input of the ID and the calculation of the time difference between different event data in Patent Document 1, there is a problem as to whether the process simply took time or not. Can not distinguish whether it takes more time than normal work time.
Furthermore, when the portable terminal is left standing and called to cheer on other areas that are not in charge, for example, work that does not involve the input of an ID occurs and accurate work analysis can not be performed.

  Therefore, while grasping the position information of the worker terminal and the carriage terminal at a certain time or when an event occurs, the information of the product to be processed is grasped from the ID information of the product or the pallet containing the product, It is desirable to provide a system that identifies and identifies a worker from image data of a camera that captures an image, and grasps the work while reducing the burden of input of the worker as much as possible based on such information.

  The present invention has been made in view of the problems in the above-mentioned conventional system for grasping work in a physical distribution warehouse, and the object of the present invention is to provide position information of a worker terminal and a carrier terminal and a pallet storing products. An object of the present invention is to provide a system for grasping work in a distribution warehouse which grasps divided work based on ID information and image data obtained by photographing the inside of the distribution warehouse.

According to the present invention, there is a system for grasping work in a distribution warehouse according to the present invention, which is made to achieve the above object, which is a system for grasping work in a distribution warehouse divided into areas by work areas. A carrier terminal, a position sensor for detecting the positions of the worker terminal and the carrier terminal, a camera for photographing the inside of the distribution warehouse, and an information management server, the worker terminal and the carrier terminal An ID identification means for recognizing or reading an ID tag provided for each product or each pallet containing a predetermined number of products, and a communication means, wherein the information management server detects a predetermined time or an event from the position sensor A position information management unit for receiving and storing and managing position information of a worker terminal and a carrier terminal every time together with the received time, the worker terminal or the carrier ID information management unit that receives and stores ID information of the ID tag identified by the ID identification means from the end and stores it along with the received time, and receives image data obtained by shooting the inside of the distribution warehouse from the camera and shooting time And an operation analysis unit for grasping an operation subdivided based on the position information, the ID information, and the image data , wherein the operation analysis unit is set in advance. The standard work pattern includes the timing at which the ID identification means identifies the ID tag, the presence or absence of movement of the worker terminal or the carrier terminal, and the worker terminal or the carrier terminal A plurality is set based on a combination with the area where the work area is located, and the work analysis unit corresponds to which standard work pattern the position information and the ID information correspond to Judging and grasping the subdivided work, the information management server sets a standard working time for each of the plurality of standard working patterns, and it is determined that a work not corresponding to the plurality of standard working patterns occurs. If it is determined or if work exceeding the standard work time occurs, an input request is sent to the worker terminal or carrier terminal to input the processing content, and the work or standard that does not apply to the standard work pattern It is characterized in that image data obtained by photographing an operation exceeding the operation time is stored in association with the input request .

  The information management server includes an image recognition unit for identifying a worker, identifies a worker who operates the worker terminal or the carrier terminal from the image data, and uses the identified worker as a standard work pattern. It is preferable to associate and save as a worker of the subdivided work determined based on the basis.

  The information management server includes, based on the position information and the image data, image data of a time detected by detecting a time when a worker acts away from a worker terminal or carrier terminal managed by the worker. Preferably, the image data is stored so as to be searchable, and an input request is transmitted so as to input the processing content to a worker terminal or a carrier terminal managed by the worker when a predetermined time or more has elapsed.

  The information management server may totalize the work determined based on the standard work pattern and the work input in response to the input request, and generate work content tabulation data and a per-shipper task time tabulation data. preferable.

According to the distribution warehouse internal work grasping system according to the present invention, the operation is based on the position information of the worker terminal and the carriage terminal, the ID information of the product or the pallet containing the product, and the image data obtained by photographing the distribution warehouse. Since an input request for inputting work contents is sent only when it is difficult to grasp the work, for example, it is grasped and the work is performed out of the work area in charge, the worker is required to understand the work unless the input request is sent. An input is unnecessary, and it is possible to realize a work grasping system that places less burden on workers.
In addition, when the standard work pattern is set in advance, the work is grasped in more detail, and the input request for inputting the work content is sent only when the work that does not correspond to the standard work pattern occurs, so the burden on the operator is small. A work grasp system can be realized.

  Further, according to the distribution warehouse internal work grasping system according to the present invention, even in the operation corresponding to the standard operation pattern, when a special circumstance occurs that exceeds the preset standard time, an input request for inputting the contents is Since the image data at that time is stored so as to be searchable while being sent to the worker terminal or the carrier terminal, it is possible to accurately grasp problems by work analysis and clarify measures for improvement.

  Further, according to the system for grasping work in the distribution warehouse according to the present invention, even when the operator moves leaving the operator terminal or leaves the carrier terminal, it is possible to capture from the image data, and in this case also Since the input request to be input is sent to the worker terminal or the carriage terminal, when the worker returns, the processing content in between is inputted, so that the work can be grasped more accurately.

It is a flowchart for demonstrating the method of operation recording and analysis of the operation grasping | ascertainment system in a physical distribution warehouse by embodiment of this invention.

Next, a specific example of the mode for carrying out the in-distribution warehouse operation grasping system according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram schematically showing the configuration of an in-distribution warehouse operation grasping system according to an embodiment of the present invention.
Referring to FIG. 1, the system for grasping work in a physical distribution warehouse 1 according to the embodiment of the present invention is an information management server 10 connected via a network 5, an operator terminal 20, a carrier terminal 30, a worker terminal 20 and a carrier The position sensor 40 which detects the position of the terminal 30, and the camera 50 which image | photographs the inside of a physical distribution warehouse are included.

  In the distribution warehouse operation grasping system 1 according to the present invention, the product input to the worker terminal 20 or the carrier terminal 30 each time the information management server 10 processes a product with the worker or the carrier operated by the worker Information received, position information of the operator terminal 20 or the carrier terminal 30 detected by the position sensor 40 at predetermined time intervals or at every occurrence of an event, and image data in a warehouse photographed by the camera 50, and the received information The image data is stored in association with the time when the information was received and the shooting time of the image data, and the information of the received product, the position information of the worker terminal 20 or the carrier terminal 30, the worker from the image data in the warehouse It is a system that grasps each subdivided work.

In the distribution warehouse internal work grasping system 1 according to the embodiment of the present invention, when inputting product information in order to save labor of an operator, an ID tag provided for each product or each pallet containing the product The input can be easily made by recognizing or reading. In addition, in grasping the work of the worker, the input time of the information of the product or the time when the information management server 10 receives the information of the product, the position information of the worker terminal 20 or the carrier terminal 30 at that time, Based on the image data, it is possible to know which worker has performed which product and when the processing has been performed, so that it is possible to grasp the work without the worker inputting the contents of the work.
When the standard work pattern is set in advance, the work pattern of the worker is extracted based on the input time of the product information, the position information of the worker terminal 20 or the carrier terminal 30 at that time, and the image data, and the information It is judged whether or not the standard work pattern provided in the management server 10 is met, and if it can be judged as a standard work pattern, the work category is decided as it is, and only when it can not be judged as a standard work pattern In order to request the input of the processing content at that time, it is a system which can minimize the input for work grasping by the worker to the necessary minimum.

  Referring to FIG. 1, the information management server 10 includes a control unit 11, an input / output unit 12, a storage unit 13, a display unit 14, a position information management unit 15, an ID information management unit 16, an image data management unit 17, and work analysis. Section 18 is included.

  The position information management unit 15 receives position information of the worker terminal 20 and the carrier terminal 30 for each of a predetermined time or when an event occurs from the position sensor 40, and stores and manages the position information together with the received time. Here, the event indicates that an operation such as inputting information to the worker terminal 20 or the carrier terminal 30 has been performed. In order to grasp the presence or absence of movement of the worker terminal 20 and the carrier terminal 30, it is preferable to receive position information at regular intervals regardless of the presence or absence of an event.

  There are various methods such as a method using a wireless LAN and a method using RFID for detecting indoor position information, but the position sensor 40 used in the work storage system in the distribution warehouse 1 includes the operator terminal 20 and the carrier terminal 30. The method is not particularly limited as long as the position in the distribution warehouse can be detected. For example, in the method of obtaining the position by the three-point survey from the difference in arrival time of the signal radio waves between the worker terminal 20 or the carrier terminal 30 and the plurality of position sensors 40, the worker is Although data processing for calculating the positions of the terminal 20 and the carrier terminal 30 is required, in the case of such a method, the position information managing unit 15 integrates information from a plurality of position sensors 40 and calculates position information. After the position information is calculated by a separate processing device, the position information of the calculation result may be received, or the position information management unit 15 may use the operator terminal 20 or the conveyance based on the information from the plurality of position sensors 40. Data processing means may be provided to calculate the position of the car terminal 30, and information from each position sensor may be received.

The position information management unit 15 receives the position information of the received worker terminal 20 or carrier terminal 30, the time when the position information was received, and the terminal corresponding to the position information (the worker terminal 20 or the carrier terminal 30, When the worker terminal 20 and the carrier terminal 30 are not particularly distinguished, they are collectively managed in a position information management table in which the type of the terminal is used as a generic term. Here, in addition to the classification of the worker terminal 20 and the carrier terminal 30, the type of the terminal also includes identification of a plurality of the worker terminal 20 and the carrier terminal 30, if any. Further, the position information management table determines which area in the distribution warehouse the position where the terminal is detected is based on the position information and stores the area together in the position information management table.
When the position sensor 40 includes a clock, the position information may include the time when the position information is acquired, but in the embodiment, the position information acquired by the position sensor 40 is immediately transmitted to the information management server 10 Since the information management server 10 substantially does not differ from the time when the position information is received, the position information management table uses the time when the position information is received.

  The ID information management unit 16 receives, from the worker terminal 20 or the carrier terminal 30, the ID information of the ID tag identified by the ID identification means respectively provided, and stores and manages in the ID information management table along with the received time. . The ID tag contains identification information for managing the products handled in the distribution warehouse, and if it is difficult to prepare for each product, or if it is difficult to attach each product individually, prepare for each pallet to store and handle a predetermined number of products. Be If an ID tag is provided for each pallet, identify the pallet's ID tag by registering the list of products stored in the pallet in association with the pallet's ID tag when the product is stored in the pallet. Thus, it can be determined that the process is for the stored product. The ID tag may be printed as in a two-dimensional code or written in RFIC.

The ID tag is identified when the product is handled by the worker terminal 20 or the carrier terminal 30, so the ID information was received from the worker terminal 20 or the carrier terminal 30, and the time and ID information were received. By storing and managing together with the type of terminal, it is possible to identify when and at which terminal the product has been processed.
When the worker terminal 20 or the carrier terminal 30 includes a clock, the ID information may include the time when the worker terminal 20 or the carrier terminal 30 identifies the ID tag, but in the embodiment, the worker terminal 20 or the carrier terminal 30 Since the ID information of the ID tag identified by the car terminal 30 is immediately transmitted to the information management server 10, it is substantially the same as the time when the information management server 10 receives the ID information, so to manage.

  The image data management unit 17 receives image data obtained by imaging the inside of the distribution warehouse from the camera 50, and stores and manages the image data together with the imaging time. In the distribution warehouse, workers often move products in the distribution warehouse by transferring products or carrying out various operations. In addition, it is preferable that a worker who operates each terminal is fixed, but depending on the configuration of the distribution warehouse, a plurality of workers may use terminals provided for each area in turn. Even when the worker operating each terminal is fixed, for example, when the worker places the terminal and moves to another area and performs a support operation, etc. I can not correctly grasp the work content.

  Therefore, in the distribution warehouse operation grasping system 1, the camera 50 is installed in the distribution warehouse, and it is grasped which operator is performing what type of operation. The image captured by the camera 50 may be a moving image, or may be a still image captured at a predetermined interval or detected by detecting the movement of the worker.

Although the image data management unit 17 receives the image data sent from the camera 50 and stores it together with the shooting time, the operator can not be identified by this alone, so the image data management unit 17 is an image recognition means for specifying the operator. The operator is specified from the image data to perform the operation of the terminal. When a plurality of workers are included in the image, the image recognition means uses face recognition technology to identify the workers, and determines the positions at which the workers are recognized, and the positions recognized as the workers, photographing The stored time may be associated with the image at that time, and may be stored and managed in the image data management table.
Usually, since the camera for monitoring saves the shooting time in cooperation with the shot image, in the embodiment, the image data is saved along with the shooting time, but the image data is immediately taken by the camera 50 and the information management server 10 immediately. The time when the information management server 10 receives the image data and the received image data may be stored in association with each other.

Further, when a plurality of cameras 50 are installed in the distribution warehouse, the image data management unit 17 stores the images so that they can be identified by which camera 50. The installation area of each camera 50 is specified according to which camera 50 the image data of the camera 50, and the recognized position in the image of the camera 50 further identifies the exact position of the worker in the distribution warehouse.
When the image of the camera 50 is a moving image, a still image may be cut out at predetermined time intervals, and the worker and its position may be recognized from the cut out image.

The work analysis unit 18 grasps the work subdivided based on the position information of the terminal, the ID information, and the image data. As described above, since position information, ID information, and image data are all stored in association with the acquired time, position information, ID information, and image data of terminals of the same or closest time of each information are stored. By combining these, it is possible to understand when and where the workers processed which products.
In the distribution warehouse divided into areas, the basic work is often decided for each area, and the work analysis unit 18 can identify the area in which the terminal is located from the position information of the terminal, so processing the product there The task can be specified by applying the basic task corresponding to the identified area.

  There are various operations such as warehousing, sorting, and picking up in the distribution warehouse, but there are standard individual operations. For example, in the storage operation, product information is continuously input. When all the information necessary for management is included in the ID tag in the accepted state, identification of the ID tag is continuously performed. If there is information that is insufficient with the ID tag alone, the combination of the input work and the identification work of the ID tag is continuously performed. In addition, when handling products that do not have an ID tag for each product, use a pallet, and enter the product information to be stored in the pallet and the pallet ID tag information input to register the product information and pallet ID tag association. It will be done continuously.

On the other hand, in the case of pickup work, move to the storage area where the necessary products are stored, take out the products, input the information of the products, recognize the ID tag, etc. and then return to the original work place The combination of movement and input work is repeated.
Thus, the standard work pattern defined for each work can be registered in advance as a standard work pattern, and the subdivided work can be grasped depending on whether or not the work according to the standard work pattern is performed. . A plurality of standard work patterns are set based on the combination of the timing at which the ID identification means of the terminal identifies the ID tag, the presence or absence of movement of the terminal, and the area in which the terminal is located.

The work analysis unit 18 determines which standard work pattern the position information and ID information of the terminal correspond to, and grasps the subdivided work.
For example, when a combination of identification of ID tag or input of product information and identification of ID tag is continuously performed in the warehousing area, it is registered as a standard work pattern of warehousing work, and the work pattern of the worker is If the work pattern is followed, it is determined that you are engaged in warehousing work.
The work analysis unit 18 stores such standard work patterns for each work and uses them for grasping the work.

  Moreover, in the embodiment, a standard work time is set to each of the standard work patterns. For example, in the case of a warehousing operation, the maximum value of the standard operation for processing the product is set as the standard operation time. The work analysis unit 18 determines that the worker is engaged in this work while the work pattern of the worker conforms to the standard work pattern and the processing of each work falls within the standard work time. Do. On the contrary, if the work analysis unit 18 does not conform to the standard work pattern, or if the work processing does not fall within the standard work time even if the work pattern conforms to the standard work pattern, the work is performed It is determined that the work category can not be specified, and an input request for inputting the processing content is transmitted on the assumption that a nonstandard work has occurred on the terminal of the worker who performs the work. At this time, image data obtained by photographing an operation not corresponding to the standard operation pattern or an operation exceeding the standard operation time is stored in association with the input request. This allows, for example, the manager of the distribution warehouse to confirm in the image what non-standard work has been performed later.

  If the combination of movement such as pickup work, product input, movement with product is different from standard work pattern, standard working time is set for each movement such as movement, product input, movement with product It may be set for each work pattern of combination of movement, product input, movement with product.

  When the processing analysis unit 18 receives the processing content input from the terminal in response to the processing content input request, the processing analysis unit 18 stores the processing content in association with the time zone in which it is determined that the work segment can not be identified. The work analysis unit 18 may divide such work for which the work classification can not be identified into other work, or may be included in the work classification if the specific work can be classified according to the processing content input from the terminal.

In addition, the work analysis unit 18 determines the position of the terminal and the position of the worker recognized from the image data based on the position information of the terminal and the image data, so that the worker manages the worker terminal 20 or transport The worker terminal 20 or the carrier vehicle which detects the time of acting away from the car terminal 30 and stores the image data including the image data of the detected time in a searchable manner and the predetermined time or more elapses An input request is transmitted to the terminal 30 to input the processing content. In this case, the time zone in which the worker has been away from the terminal may be divided into other tasks or tasks away from the terminal, or as described above, in response to the request for processing content input, the processing content input from the terminal If the work can be classified, it may be included in the work classification.
As described above, the image data at this time may be stored in association with the input request when the worker leaves the terminal.

  Further, the work analysis unit 18 is provided with a totaling means, and the work determined based on the position information of the terminal, the ID information, and the image data for each worker, or further based on the standard work pattern, and the input The work content tabulation data is created by totaling the work input in response to the request, totaling the work content for each worker and the time when the work was performed from the information of the processed product and the like, Output the result as a table or graph. Further, the work time processed by each worker is totaled for each shipper that is the product storage destination, work time total data for each shipper is generated, and the result is output as a table or a graph.

  The input / output unit 12 receives the position information of the terminal from the position sensor 40 via the network 5, acquires the image data from the camera 50, and the product information or the like from the worker terminal 20 or the carrier terminal 30. Receive identification information of ID tag. To this end, communication means are provided to communicate with these devices. The information management server 10 is also provided with an input unit such as a keyboard or a mouse for inputting settings such as setting conditions for aggregation.

The storage unit 13 stores various data, a control program for controlling the information management server 10 itself, and the like. The storage unit 13 is embodied by a hard disk, a semiconductor memory, or the like.
The display unit 14 displays an operation screen of the information management server 10, data such as image data and various aggregation data, and a control program.
The control unit 11 controls the operation of the information management server 10 according to the control program, and controls each component to perform the above-described function.

The worker terminal 20 is a portable terminal carried by a worker, and includes a control unit 21, an input / output unit 22, a storage unit 23, a display unit 24, and an ID identification unit 25.
The ID identification unit 25 includes an ID code identification unit that recognizes or reads an ID tag, and when print data such as a two-dimensional code is used as an ID code, a camera unit that captures an image of the printed ID code; And a reading unit that reads ID information included in the ID code from the image. In the case of a printed ID code, when processing the product, reading is performed by pointing the camera of the ID identification unit 25 to the ID code or pointing it to the ID code and operating the reading switch.
When an RFID is used as an ID code, the ID identification unit 25 includes an RFID reader / writer. In the RFID, when the RFID and the reader / writer approach a predetermined distance, communication is performed between the reader / writer and the RFID, and the ID information of the RFID is recognized by the reader / writer.

  The input / output unit 22 inputs processing content in response to an input request transmitted from the information management server 10 in response to the input of information other than the ID information obtained from the ID code or the occurrence of work other than the standard work pattern. Including keys. Since the ID information of the ID code, the product information lacking by itself, and the input processing content for the input request are transmitted to the information management server 10, the input / output unit 22 includes a communication means.

The display unit 24 displays a message such as the recognized ID information or an input request from the information management server 10. Although the display unit 24 is embodied by a liquid crystal display or the like, a touch panel liquid crystal display may be used to double as the character input means of the input / output unit 22.
The storage unit 23 temporarily stores input data, and stores a control program of the worker terminal 20. The storage unit 23 is embodied by a semiconductor memory or the like.
The control unit 21 controls the operation of the worker terminal 20 according to the control program, and controls each component to perform the above-described function.
The worker terminal 20 can be embodied by a smartphone, a tablet terminal, or the like.

  The carrier terminal 30 is individually provided to a carrier used in the distribution warehouse, and corresponds to the worker terminal 20 of the worker when the worker who operates the carrier is fixed. However, if the vehicle is installed in a manner to be shared by a large number of workers in the warehouse, the vehicle terminal 30 is used to identify the work by the vehicle. As described above, while the worker terminal 20 is used for grasping the work of the worker, the carrier terminal 30 is used for grasping the work of the carrier, but the worker terminal 20 and the carrier terminal 30 are different. The configuration with is almost the same.

  That is, although the carrier terminal 30 includes the control unit 31, the input / output unit 32, the storage unit 33, the display unit 34, and the ID identification unit 35, these components are the control unit 21 of the worker terminal 20 and the input / output unit 22 respectively. Corresponds to the storage unit 23, the display unit 24, and the ID identification unit 25. When the transport vehicle terminal 30 is fixed to the transport vehicle, reading of the ID tag becomes difficult, so an external reading unit such as a two-dimensional code reader connected to the transport vehicle terminal 30 by wire or wireless is provided. It is also good. Since it overlaps with description of each component of worker terminal 20 except this, detailed explanation of composition of conveyance vehicle terminal 30 is omitted.

  A plurality of position sensors 40 are installed on a ceiling or the like in the distribution warehouse in order to specify the position of the terminal. As described above, as long as the position of the terminal can be specified, the method of position sensing of the position sensor 40 does not matter. The sensor 40 communicates with the position information acquisition unit 43 in order to acquire data for specifying the position of the terminal and transmit it so as to reach the information management server 10 regardless of the presence or absence of a processing device that calculates the position information separately. And an input / output unit 42 including means. Moreover, the control part 41 which controls position sensor 40 self is provided. In order to correctly determine the position of the terminal, a plurality of position sensors 40 are installed apart from each other in plan view. Therefore, an address or identification number is assigned to each terminal, and when transmitting data from the position sensor 40, it is transmitted along with this address or identification number.

The camera 50 photographs the inside of the distribution warehouse, but since the photographed image data is used to identify and identify the worker, when the distribution warehouse is wide, a plurality of them are installed so as not to cause a blind spot.
The camera 50 includes an image acquisition unit 53 and an input / output unit 52 that outputs the acquired image data to the information management server 10, and includes a control unit 51 that controls the image acquisition unit 53 and the input / output unit 52.
The camera 50 used in the in-distribution warehouse operation grasping system 1 may have any resolution as long as it can be identified by the operator, and is realized by a commercially available surveillance camera.

  A network 5 is a communication line used to exchange information between the information management server 10 and the worker terminal 20, the carrier terminal 30, the position sensor 40, and the camera 50, and may be a local network such as a LAN in a distribution warehouse. The network 5 may be a wide area network such as the Internet when the information management server 10 collectively manages information from a plurality of distribution warehouses installed apart from each other.

FIG. 2 is a diagram schematically illustrating the configuration of the intra-distribution warehouse operation grasping system according to the embodiment of the present invention.
Referring to FIG. 2, in one embodiment, a worker terminal 20 processing a product, a carrier terminal 30 processing another product, and a position for detecting the positions of the worker terminal 20 and the carrier terminal 30. The sensor 40 and the camera 50 which image | photographs the condition of the operator terminal 20 and the conveyance vehicle terminal 30 are shown.

  In the embodiment, the products are stored in pallets 210, and each pallet 210 is provided with an ID tag 220 unique to each pallet 210. The product stored in the pallet 210 is input to the operator terminal 20 when stored in the pallet 210, and the ID tag 220 of the pallet 210 is read when storage is completed, thereby the information and ID of the stored product The information of the tag 220 is sent to the information management server 10, and the information of the ID tag 220 of the pallet 210 is associated with the information of the product in the information management server 10 and registered. FIG. 2 shows an example of processing such registered products.

  When the worker finishes processing the product stored in the registered pallet 210, the ID information of the ID tag 220 is immediately transmitted to the information management server 10 when the ID tag 220 of the pallet 210 is read. In the information management server 10, when the ID tag 220 is read, it is identified by the ID information that the processing of the product associated with the ID tag 220 has been performed.

  Similarly, when a worker who handles a carriage stores the registered pallet 210 in, for example, a storage area and reads the ID tag 220 at the carriage terminal 30, the ID information is immediately transmitted to the information management server 10, and the information management server When the ID tag 220 is read at 10, it is identified that the product associated with the ID tag 220 has been stored in the storage area.

A plurality of position sensors 40 are installed above the worker terminal 20 and the carrier terminal 30, for example, on a ceiling, and detect positions of the worker terminal 20 and the carrier terminal 30 for each predetermined time to obtain position information on the information management server 10 Send to
A plurality of cameras 50 are also installed above the worker terminal 20 and the carriage terminal 30, and image data captured by the camera 50 is transmitted to the information management server 10.

Therefore, the information management server 10 analyzes the work based on the information. Is done.

FIG. 3 is a view exemplarily showing area divisions and work contents of the physical distribution warehouse according to the embodiment of the present invention. There are various types of distribution warehouses depending on the products to be handled and the size of the distribution warehouse. Therefore, in describing the details of the embodiment of the present invention with reference to FIG. 4 and the subsequent figures, in order to set preconditions and to explain accordingly, it is assumed that the physical distribution warehouse shown in FIG.
Referring to FIG. 3, the distribution warehouse 300 includes an area of a receiving area 310, a sorting area 320, a storage area 330, a pickup area 340, a packing area 350, and a shipping area 360.

  In the warehousing area 310, warehousing operation of the product sent from the maker of the delivery source is performed. In FIG. 3, products A1 and A2 are delivered from company A, and products B1 and B2 are delivered from company B in the same manner. In the warehousing operation, the item name, the quantity, and the like of the delivered product are input to the operator terminal 20, and after being received, they are transported by the pallet 210 and the product is stored in the pallet 210. Each pallet 210 is provided with a unique ID tag 220.

In the sorting area 320, products are reorganized according to type, and after being stored in the pallet 210, the ID tag 220 is read, and the product and the pallet 210 are associated. The sorted products are transported to the storage and stored in the corresponding product shelf. From this sorting to storage is considered as sorting work.
In the pickup area 340, products to be shipped per shipper are taken out from the storage area and accumulated. Move from the pickup area to the storage area, select and take out the necessary products in the storage area, and let it be picked up until it is transferred to the pickup area.

In the packing area 350, the products accumulated for each shipper are packed and stored in a box or container so that they can be shipped together. A shipping label including information of contents is attached to the packed box or container, and the shipping label includes an ID code such as a two-dimensional code including information of contents.
In the shipping area 360, the packaged product is loaded onto a shipping truck and shipped to the shippers a and b.
In addition, in the storage area, inventory work is performed regularly to check the stock status.

  It is needless to say that the above-described distribution warehouse 300 is merely an illustration for explanation, and the in-distribution warehouse operation grasping system 1 according to the embodiment of the present invention can be applied according to the actual forms of various distribution warehouses.

FIG. 4 is a diagram showing a standard operation pattern of the distribution warehouse according to the embodiment of the present invention.
FIG. 4 shows a standard work pattern corresponding to each area in the distribution warehouse 300 and the work performed in each area.

  In the receiving area 310, a receiving operation is performed. In the storage operation, the operator terminal 20 is used to sequentially input the product name, the quantity, and the like of each delivered product. In the example of FIG. 3, the input of the product A1, the input of the product A2, the input of the product B1, and the input of the product B2 are sequentially performed. Therefore, in the warehousing operation of the warehousing area, repetition of product input is set as a standard operation pattern. In addition, in not only the warehousing operation but also in the product input, when all the necessary information is included in the ID tag, the product input is performed by reading or identification of the ID tag.

  In the sorting operation performed through the sorting area 320 and the storage area 330, the sorted product is input, the sorted product is transported to the storage area, and the working pattern of returning to the original work place is repeated. In the sorting operation, an operation pattern of product input, movement with the product, and movement in the air is set as a standard operation pattern.

In the storage area 330, an inventory operation is performed. In the inventory operation, since the information of the products stored in the storage rack is sequentially input, the repetition of the product input is set as the standard operation pattern.
In the picking operation performed through the pickup area 340 and the storage area 330, the work pattern is moved from the pickup area 340 to the storage area 330, the product is taken out, the product information is input, and the taken out product is brought back to the pickup area 340. Is repeated, so that the work pattern of empty movement, product input, and movement together with the product is set as a standard work pattern.

In the packing area 350, the packing work is performed, and after packing up the products accumulated in the pickup work for shipping, the shipping label is attached. By inputting the information of the product to be packed and reading the ID code included in the shipping label after packing, the product to be packed is associated with the ID code of the packing box. In the packing operation, an operation pattern for inputting the package following the input of the bundled product is set as a standard operation pattern.
In the shipping area 360, the shipping operation is performed, and when the product packaged for shipping is loaded on the truck, the ID code of the packing box is read and loaded on the shipping truck. In shipping work, repetition of packing input is set as a standard work pattern.

FIG. 5 is a view exemplarily showing the work contents of the worker in the distribution warehouse according to the embodiment of the present invention.
Referring to FIG. 5, the history of the work performed by the worker is shown in chronological order for each worker.
The operator A continues to input the product in the storage area, moves to the pickup area, moves to the storage area empty, and indicates that the product has been taken back to the pickup area after product input. That is, the work pattern, which is the history of the work of the worker A, is an example of the case where the pickup work is performed after the storage work is performed.

  If this work pattern is compared with the standard work pattern of FIG. 4, the repeated product input in the warehousing area of the worker A matches the standard work pattern of the warehousing work, and the work pattern in the pickup area and the storage area Is consistent with the standard working pattern of pickup work. Therefore, since these operations are identified as the warehousing operation and the pickup operation respectively in the information management server 10, the worker A does not have to register the operation contents in particular for these operations.

  The worker B enters the product in the packing area, enters the packing input, moves to the storage area, and continuously inputs the product. The work pattern of the worker B is an example of the case where the warehousing operation is performed after the packing operation. Since the packing work and the warehousing work of the worker B also conform to the standard work pattern, there is no need to register work contents in particular.

The operator C moves from the pickup area to the storage area, performs product input, returns to the pickup area with the product, moves to the packing area, returns to the pickup area again, and repeats the first work. This is an example in which, for example, the worker C in charge of pickup has a defect in the picked up product and is called from the worker in the packing area, and after confirmation, returns to the responsible department and continues the pickup work.
In this case, since the reciprocating movement from the pickup area to the packing area does not correspond to the standard work pattern and the work can not be decided, the information management server 10 requests the worker terminal 20 of the worker to input the processing contents at this time. Send

The worker D continuously performs packing input in the shipping area, moves to the outside of the warehouse, and after a while passes back to the shipping area and continuously performs packing input again. This is an example in which the worker D in charge of the shipping work is temporarily called out for a meeting and left after leaving the seat, and then returns and continues the shipping work. Also in this case, since there is no corresponding standard work pattern while leaving the seat and leaving the warehouse, the information management server 10 transmits an input request of the processing content at this time to the worker terminal 20 of the worker.
When a standard work time is set in the standard work pattern, the information management server 10 does not perform processing within the standard work time even if the work conforms to the standard work pattern. An input request for processing content is transmitted to the carrier terminal 30.

FIG. 6 is a view showing various information tables handled by the distribution warehouse internal operation grasping system according to the embodiment of the present invention.
In FIG. 6, an ID information management table 610 created based on the information received by the information management server 10, a position information management table 620, an image data management table 630, and a worker a and a worker b determined from these management tables. The respective task analysis tables 640 and 650 of FIG.

The ID information management table 610 is a table stored in association with the time when the ID information received from the worker terminal 20 or the carrier terminal 30 is received and the type of the received terminal.
Referring to the ID information management table 610, when the worker terminal (1) performs product processing at time 9:30, the ID information A0001 is read, and subsequently the worker terminal (2) receives this information at time 9:40. It indicates that the product of the ID information A0001 has been processed.

The position information management table 620 is a table stored in association with the position information of each terminal detected by the position sensor 40 at predetermined time intervals, the detected time, and the type of the detected terminal. An area determined from the position at which the terminal is detected is also associated and stored. The position of the detected terminal is represented by plane coordinates (X, Y) in the warehouse, and the area is determined by which area the coordinates are included.
For example, at time 9:30, the worker terminal (1) is detected in the storage area, the worker terminal (2) is detected in the sorting area, and the carrier terminal (1) is detected in the pickup area.

  The image data management table 630 associates the worker specified by image authentication from the image data in the distribution warehouse photographed by the camera 50, the area or position where the worker is specified, and the time when the image was photographed Is a saved table. The image data management table 630 may further store an image specifying a worker in association with the image.

Referring to the image data management table 630, at time 9:30, the worker a is identified by the storage area, the worker b by the sorting area, and the worker c by the pickup area.
A work analysis table for each worker is created by correlating the data at the same time by associating the ID information management table 610, the position information management table 620, and the image data management table 630 with each other. For example, focusing on the data at time 9:30, the worker terminal (1) that has read the ID information A0001 is located in the storage area, and the worker in the storage area at this time is the worker a. That is, it is determined that the worker a has read the ID information A 0001 using the worker terminal (1) in the storage area at time 9:30.

Similarly, it is determined that the worker b is in the sorting area with the worker terminal (2) at 9:30, and that the ID information A 0001 is read in the sorting area at 9:40.
Although the work analysis table is not shown, it is determined that the worker c is also operating the carrier at 9:30.
As described above, the position of each time can be automatically determined by both the worker and the terminal, so it is easy to grasp the movement of the worker, and it is easy to determine whether the worker is moving with the terminal or moving away from the terminal. It is judged.

  In the embodiment, the work analysis table (640, 650) includes a work division column. In addition to the information obtained from the ID information management table 610, the position information management table 620, and the image data management table 630, by combining the identification of the work according to the standard work pattern described in FIGS. It is determined whether they are engaged. Thereby, the information management server 10 grasps when and where the worker is engaged in which work. In the time zone in which the worker's work conforms to the standard work pattern, the work classification is automatically specified and the work grasp is performed, so the worker does not need to input for work analysis, and the standard work pattern is used. Only when a non-applicable situation occurs, the input of the processing content is required, so the burden on the operator can be reduced as much as possible.

FIG. 7 is a flow chart for explaining the method of operation recording and analysis of the in-distribution warehouse operation grasping system according to the embodiment of the present invention.
Referring to FIG. 7, in step S710, the information management server 10 receives ID information from the worker terminal 20 or the carrier terminal 30, and at the time when the ID information is received, the ID information is associated with the received terminal type. Update the management table.

The information management server 10 receives the position information of the terminals from the position sensor 40 in step S715, and updates the position information management table in association with the position information of each terminal, the time when each terminal was detected, and the detected terminal type.
Next, in step S720, the information management server 10 receives the image data in the distribution warehouse from the camera 50, and captured the worker specified by the image authentication, the area or position where the worker was specified, and the image The image data management table is updated in association with the time.

  Although FIG. 7 shows the order of reception of ID information, reception of position information, and reception of image data, these are received in order from the terminals (20, 30) which are independent devices, the position sensor 40, and the camera 50, respectively. It does not have to be. Also, reception of ID information occurs only when the product processing is performed by the operator and the ID tag is read, while reception of position information and reception of image data are performed at predetermined time intervals. When the worker is merely moving, etc., reception of the ID information may not be performed, and only reception of the position information and reception of the image data may be continuously performed.

The information management server 10 analyzes the work analysis table for each worker based on the updated position information management table, the updated image data management table, and the updated ID information management table when the ID information is received in step S730. Update.
Next, the information management server 10 extracts a work pattern as shown in FIG. 5 from the updated work analysis table (step S730).

  Even from the extracted work pattern and the area in which the work was performed, the basic work of the area can be assigned to specify the work, but in the embodiment, the information management server is used to analyze the work in more detail. Whether the extracted work pattern matches the standard work pattern (step S 735) or the standard work pattern is compared with the standard work pattern stored in the standard work time (stage If the information management server 10 determines in step S 740) and the both fit together, the information management server 10 specifies the work category of the work pattern of the worker in step S 745. If it does not match the standard work pattern in step S735, or if the step S740 of what matches the standard work pattern in step S735 is not performed within the standard working time, the information management server 10 performs its work in step S750. A processing content input request for a task whose task content can not be identified is transmitted to the worker terminal 20 or the carrier terminal 30 handled by the person.

When the process content input by the worker is received from the worker terminal 20 or the carrier terminal 30 in step S755, the information management server 10 updates the work analysis table in step S760.
The work analysis table for each worker thus determined is stored, and is used to create work content tabulation data and shipper task time tabulation data.

  Although the embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the technical scope of the present invention. It is possible.
