DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] Hereinafter, a detailed description will be given of an embodiment of the present invention with reference to the accompanying drawings. In the following drawings, the same elements are designated by the same numbers or symbols throughout the description of the embodiment.

[0029] [Basic concept / basic configuration] FIG. 1 is a diagram for explaining the basic concept and basic configuration of a work process management system according to an embodiment of the present invention.

[0030] As shown in FIG. 1, a work process management system 1 according to an embodiment of the present invention is composed of an imaging unit 301 that images a character string 10 written on a member 6 used in work, and a display unit 302 that recognizes the character string 10 imaged by the imaging unit 301 and displays pre-stored character string candidates 20 that correspond to the recognized character string 10.

[0031] As shown in FIG. 1, a work process management system 1 for managing a work process uses a work input terminal 2 having an image capturing unit 301 to capture an image of a character string 10 written on a member 6 such as steel used at a work site.

[0032] The photographed character string 10 is recognized by the display unit 302 of the work input terminal 2. The display unit 302 displays one or more character string candidates 20 corresponding to the recognized character string 10 on the work input terminal 2, and accepts the selection by the worker 5.

[0033] The work input terminal 2 of the work process management system 1 may be, for example, an electronic device such as a smartphone or a tablet terminal having a photographing function such as a camera, and the computer 4 is, for example, an on-premise server or an on-premise computing system, or a cloud server or a cloud computing system, and in this embodiment, it is a cloud computing system.

[0034] Here, the work input terminal 2 and the computer 4 of the work process management system may be one or more, as long as they are communicatively connected via a network 3. In addition, the network 3 is not limited to a wireless communication environment such as Wi-Fi, and may be physically connected to each other using an interface such as a USB cable.

[0035] The work input terminal 2 of the work process management system 1 has at least a camera function for taking pictures, a control unit 200 including a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., and a device for enabling communication with other terminals and devices, such as a Wi-Fi compatible device, and a data storage unit such as a semiconductor memory, a recording medium, a memory card, etc., as a memory unit 210. The storage unit may be present outside and capable of network communication.

[0036] In the work input terminal 2 of the work process management system 1, the control unit 200 reads a predetermined program, thereby realizing an imaging unit 301 and a display unit 302 in cooperation with the storage unit 210.

[0037] The computer 4 of the work process control system 1 is equipped with at least a CPU, a GPU, a RAM, a ROM, etc., a device for enabling communication with other terminals and devices, such as a Wi-Fi compatible device, and a data storage unit such as a semiconductor memory, a recording medium, a memory card, etc. The storage unit may be present outside and capable of network communication.

[0038] The basic concept and basic configuration of the work process control system 1 have been described above.

[0039] [Text recognition processing] Fig. 2 is a diagram showing a character string recognition processing flow of the work process management system 1 according to the embodiment of the present invention. Fig. 3 is an image diagram showing an example of the character string recognition processing output by the work process management system according to the embodiment of the present invention. The character string recognition processing realized by the work process management system 1 will be described with reference to Figs. 2 and 3.

[0040] First, as shown in the left side of Fig. 3, the photographing unit 301 of the work input terminal 2 of the work process management system 1 photographs a character string 10 by the operation of the worker 5 (step S401). Next, the display unit 302 of the work input terminal 2 of the work process management system 1 recognizes the photographed character string 10, and displays one or more character string candidates 20 pre-stored in the storage unit 230 corresponding to the character string 10 in a selectable manner as shown in the right side of Fig. 3 (step S402).

[0041] Here, the display unit 302 of the work input terminal 2 may display one or more character string candidates 20 on the work input terminal 2.

[0042] Next, when one character string candidate 20 is selected from one or more character string candidates 20 displayed on the work input terminal 2 by operation of the worker 5 (step S403), the display unit 302 of the work input terminal 2 accepts the selected character string candidate 20 (step S404).

[0043] The character string 10 may be, for example, characters written directly with chalk or the like on a member 6 such as a steel frame used at a work site, and the written characters are not limited to numbers or letters, but may be symbols, etc.

[0044] For example, the character string candidate 20 may be learned from a character string 10 photographed in advance as training data and added as annotation data for character string recognition. The method of adding annotation data is not particularly limited, and data may be added manually or by using an automated tagging tool such as an annotation tool.

[0045] Furthermore, the character string to be learned is not limited to the character string, but may be a character or symbol unit.

[0046] Here, the learning of character string candidates 20 described above may be performed by work input terminal 2, or may be performed by computer 4 and the results of the learning may be synchronized with work input terminal 2 via network 3.

[0047] The character string recognition process is completed.

[0048] [String Identification Processing] Fig. 4 is a diagram showing a flow of a character string identification process executed by the work input terminal 2 of the work process management system 1 according to the embodiment of the present invention. Fig. 5 is an image diagram showing an example of a character string identification process output by the work process management system 1 according to the embodiment of the present invention. The character string identification process realized by the work process management system 1 will be described with reference to Figs. 4 and 5.

[0049] As shown in the left side of FIG. 5, the work input terminal 2 of the work process management system 1 according to an embodiment of the present invention determines the character string candidate 20 selected by the worker 5 and accepted by the work input terminal 2 as an identification code 30 (step S405).

[0050] Here, the determined identification code 30 is displayed as shown in the right side of FIG.

[0051] This completes the character string identification process.

[0052] [Process progress response processing] 6 is a diagram showing a process progress response process flow executed by the work input terminal 2 of the work process management system 1 according to the embodiment of the present invention. The process progress response process realized by the work process management system 1 will be described with reference to FIG.

[0053] As shown in FIG. 6, the work input terminal 2 of the work process management system 1 associates the identification code 30 with the process progress data 40 (step S406).

[0054] The process progress data 40 is, for example, data for managing the progress of a process such as work, and the corresponding data is not limited to the identification code 30, but may correspond to data regarding parts 6, property data for work or construction, process data, product data, drawing data, parts storage area data 50 described later, worker identification code 60, etc.

[0055] The process progress data 40 may be managed in synchronization with the process progress data of a computer 4 that is communicably connected to the work input terminal 2 via a network 3.

[0056] The above is the process progress response process.

[0057] [Procedure presentation process] Fig. 7 is a diagram showing a procedure presentation process flow executed by the work input terminal 2 of the work process management system 1 according to the embodiment of the present invention. Fig. 8 is an image diagram showing an example of the procedure presentation process output by the work process management system according to the embodiment of the present invention. The procedure presentation process realized by the work process management system 1 will be described with reference to Figs. 7 and 8.

[0058] As shown in FIG. 7, when the work input terminal 2 of the work process management system 1 receives input of work (construction) location items by the worker 5 (step S407), it displays the work process items and photography items so that they can be entered (step S408).

[0059] As shown on the left side of FIG. 8, if the work (construction) location item is not input, the photography item is not displayed.

[0060] In addition, the work input terminal 2 of the work process management system 1 accepts the input of the work (construction) location items, and after accepting the input of the work process items, the shooting items are displayed as shown on the right of Figure 8, making it possible to take photos, and it becomes possible to encourage the worker 5 to take photos for each work process.

[0061] By displaying items that can be entered in the above-mentioned certain procedure, it is possible to reduce the risk of missing items.

[0062] The procedure presentation process is completed.

[0063] [Rotary display and dial-type display processing] Fig. 9 is a diagram showing a rotation display and dial-type display processing flow executed by the display unit 302 of the work input terminal 2 of the work process management system 1 according to the embodiment of the present invention. Also, Fig. 10 is an image diagram showing an example of the rotation display and dial-type display processing output by the work process management system 1 according to the embodiment of the present invention. The rotation display and dial-type display processing realized by the work process management system 1 will be described with reference to Figs. 9 and 10.

[0064] The display unit 302 of the work input terminal 2 of the work process management system 1 displays the photographed character string 10 in a rotatable manner (step S409). Furthermore, the display unit 302 of the work process management system 1 displays one or more character string candidates 20 pre-stored in the storage unit 230 corresponding to the recognized character string 10 in a dial-type selectable manner (step S410).

[0065] As shown on the left side of Figure 10, worker 5 can rotate the photographed character string 10 to any angle by operating the rotation item. For example, even if character string 10 written on component 6 is photographed from an angle other than the front, such as from the opposite side, it is possible to recognize character string 10 as shown in Figure 10.

[0066] As shown on the right side of Figure 10, by displaying the character string candidates 20 in a dial format, it is possible to display even a large number of character string candidates in a small space, making it possible to facilitate operation, for example, by allowing operation with one hand.

[0067] The above is the rotary display and dial-type display process.

[0068] [Prevention of misrecognition] Fig. 11 is a diagram showing a flow of the misrecognition prevention process executed by the work input terminal 2 of the work process management system 1 according to the embodiment of the present invention. Fig. 12 is an image diagram showing an example of the misrecognition prevention process output by the work process management system 1 according to the embodiment of the present invention. The misrecognition prevention process realized by the work process management system 1 will be described with reference to Figs. 11 and 12.

[0069] As shown in FIG. 11, when an extra character, character string, or stain is photographed and the character string 10 differs from a pre-stored character string candidate 20 (step S411), the work input terminal 2 of the work process management system 1 does not recognize the extra character, character string, or stain as a character string candidate 20 (step S412).

[0070] Here, even if the extra character, character string, or stain matches a pre-stored character string candidate 20, it may be recognized as the extra character, character string, stain, or unnecessary character, for example, if it matches an excluded item that has been set in advance in correspondence with the work (construction) location item or the work process, etc., as described above.

[0071] The unnecessary characters, character strings, and stains may be added as annotation data for unnecessary character recognition by learning unnecessary characters, character strings, and stains that have been photographed in advance as teacher data, for example. The method of adding annotation data is not particularly limited, and data may be added by a manual method, a method using an automated tagging tool such as an annotation tool, or the like.

[0072] As shown in FIG. 12, the work input terminal 2 of the work process management system 1 is able to recognize the character string 10 shown in a solid line frame without erroneous recognition by excluding unnecessary characters and stains shown in a dashed line frame from the photographed character string.

[0073] This is the process for preventing erroneous recognition.

[0074] [Storage area management processing] Fig. 13 is a diagram showing a yard management processing flow according to an embodiment of the present invention, which is executed by the work input terminal 2 of the work process management system 1 according to an embodiment of the present invention. Fig. 14 is an image diagram showing an example of yard management processing output by the work process management system according to an embodiment of the present invention. The yard management processing realized by the work process management system 1 will be described with reference to Figs. 13 and 14.

[0075] As shown in FIG. 13, the work input terminal 2 of the work process management system 1 registers the identification code 30 and the material storage yard data 50 in association with each other (step S413).

[0076] The association between the identification code 30 and the material storage site data 50 is not limited to registration by the work input terminal 2 as shown in FIG. 14, but may be registration by directly operating the computer 4, for example.

[0077] The material storage location data 50 is data indicating the storage location of the material, for example, as shown on the right side of Figure 14. For example, by selecting an item of the material storage location data 50 as shown on the left side of Figure 14, the identification code 30 can be registered in correspondence with the determined material 6, making it possible to easily manage the material 6 and its storage location.

[0078] The above is the storage yard management process.

[0079] [Worker identification process] Fig. 15 is a diagram showing a flow of a worker identification process according to an embodiment of the present invention, which is executed by the work input terminal 2 of the work process management system 1 according to an embodiment of the present invention. Fig. 16 is an image diagram showing an example of a worker identification process output by the work process management system according to an embodiment of the present invention. The worker identification process realized by the work process management system 1 will be described with reference to Figs. 15 and 16.

[0080] As shown in FIG. 15, the work input terminal 2 of the work process management system 1 according to the embodiment of the present invention associates the work input terminal 2 with the worker identification code 60 (step S414).

[0081] As shown in FIG. 16, the work input terminal 2 used by the worker 5 is operated to select a worker identification code 60, whereby the work input terminal 2 and the worker identification code 60 are associated with each other.

[0082] Incidentally, the association between the work input terminal 2 and the worker identification code 60 is not limited to being established by an operation using the work input terminal 2, but may be established by directly operating the computer 4, for example.

[0083] The worker identification code 60 is an identification code for managing which worker operated the work input terminal, and by associating and identifying the worker with the work input terminal used, it becomes possible to easily manage processes and parts.

[0084] This completes the worker identification process.

[0085] The photographing unit photographs a plurality of character strings written on a member to be used in the work, the display unit recognizes each of a plurality of character strings photographed, and displays pre-stored character string candidates corresponding to the recognized character strings; 2. The work process management system according to claim 1, wherein one or more of the character string candidates are displayed to the worker so that the worker can select from the displayed one or more character string candidates, and the worker's selection is accepted for each character string.

[0086] According to this type of work process management system, the characters written directly on the components used in the work are read as an image and the identification code is recognized, so that it is possible to provide a work process management system that improves the convenience of component management by directly reading the characters written on the components without physically labeling the components with paper, stickers, etc.
