<<<<Overview of this embodiment>>>>
In general, in the management of an organization such as a company, it is necessary to reduce costs and improve operational efficiency to improve performance using a limited number of personnel. In recent years, the concept of "total optimization" has been attracting attention as a measure to solve such management issues. This "overall optimization" means a state in which the entire organization, such as a team, section, or segment, is optimal. By achieving overall optimization, various effects can be expected such as improved business efficiency, cost reduction, and improved labor productivity.

In contrast to this "total optimization," there is a concept called "partial optimization." This "partial optimization" generally means that a part of an organization or an individual is in an optimal state. However, in order to maximize the performance and profits of the organization as a whole, it is necessary to go beyond just "partial optimization" and aim for overall optimization.

Therefore, the present invention makes it possible to easily perform overall optimization regarding the manufacture of various products. FIG. 1 schematically shows a manufacturing information management system 100 according to this embodiment. The manufacturing information management system 100 of this embodiment targets steel pipes as a product and targets a steel pipe manufacturing process as a manufacturing process. The manufacturing information management system 100 detects various events occurring in the steel pipe manufacturing process, performs predetermined information processing based on the detection results, and provides information regarding steel pipe manufacturing.

For manufacturing steel pipes, it is possible to employ a steel pipe manufacturing line as shown in FIG. 10, for example. The steel pipe manufacturing line shown in FIG. 10 is a manufacturing system that employs a line production method. Below, a steel pipe manufacturing line shown in FIG. 10 will be described as an example of a manufacturing process, and then a manufacturing information management system 100 applied to the steel pipe manufacturing line will be described.

＜＜＜＜Steel pipe manufacturing line＞＞＞＞
FIG. 10 is a schematic diagram showing the configuration of a steel pipe manufacturing line. The steel pipe manufacturing line shown in FIG. 10 includes a coil A1, an uncoiler A2, a forming device A8, an inner surface hot dip metal plating device A6, a welding device A9, a cutting device A11, an outside surface hot dip metal plating device A14, a sizing device A16, and a cutting device. It includes the device A17 and the like.

Among these, the uncoiler A2 continuously supplies a long steel plate (strip steel) wound around the coil A1. The forming device A8 continuously forms the steel plate supplied from the uncoiler A2 into a tubular shape. The inner surface hot-dip metal plating apparatus A6 hot-dip coats a desired metal onto a steel sheet immediately before continuously forming the steel sheet into a tubular shape. The welding device A9 forms a tubular body by continuously welding the longitudinal end surface joints of the plated steel plate formed into a tubular shape.

The cutting device A11 continuously cuts the weld bead formed on the outer surface of the tubular body. The external surface hot-dip metal plating apparatus A14 has a plurality of (for example, four) immersion parts, and continuously applies hot-dip metal plating to the external surface of the tubular body to form a hot-dip metal-plated steel pipe. The sizing device A16 shapes the hot-dip galvanized steel pipe to standard dimensions. The cutting device A17 cuts the hot-dip galvanized steel pipe into a predetermined length.

If necessary, a shot blasting device A3, cleaning devices A4 and A12 that clean the strips and tubular bodies with high-pressure water or chemical solutions, dry the outer surface of the strips and tubular bodies, and clean the strips and tubular bodies It is also possible to provide heating devices A5 and A13 for preheating and seal in a reducing atmosphere. Depending on the properties of the plated metal, a first cooling tank A7 for cooling the steel plate after hot-dipping and a second cooling tank A15 for cooling the tubular body after hot-dipping are provided. The cooling tank is indispensably provided when the metal plating is zinc plating.

In this example, as a pretreatment for the steel plate to be plated, the Sendzimer method is used, in which the surface of the steel plate is cleaned, dried and preheated in a reducing atmosphere, but other known methods may be used for pretreatment. Processing may be performed. For example, the flux method (a method in which a flux liquid for oxidation prevention is applied, dried, and preheated), U. S. A known method such as a steel method (a method in which rolling oil adhering to the steel sheet surface is removed by an alkaline electrolytic cleaning device and then pickling is performed) may be applied. Further, the steel plate may be pickled or washed with water at an appropriate timing.

Next, a method for manufacturing steel pipes using the above steel pipe manufacturing line will be described. First, a coiled steel plate is continuously supplied from the uncoiler A2 toward the downstream side of the line. Subsequently, after a predetermined pretreatment is performed by shot blasting device A3 and cleaning device (strip body cleaning device) A4, it is sent to heating device (strip body heating device) A5 and heated, and its outer surface is dried. Ru. The supplied steel plate is subjected to an inner surface plating process on one side by the inner surface hot-dip metal plating apparatus A6. Subsequently, after cooling the steel plate plated on one side in the first cooling tank A7, the steel plate is drawn into the forming device A8 and cold-formed into a tubular shape, and the longitudinal end surface joint of the steel plate is made continuous by the welding device A9. are welded together to form a continuous tubular body A10.

Next, the tubular body A10 is sent to a cutting device A11 which is equipped with a cutter having a shape that follows the outer surface of the tubular body A10. Then, the weld bead portion formed on the outer surface of the tubular body A10 is shaved off by the cutting tool of the cutting device A11, and the outer surface of the tubular body A10 is formed smoothly.

After that, the tubular body A10 is subjected to the same predetermined cleaning as the steel plate in the tubular body cleaning device A12, and the tubular body A10 is sent to the tubular body heating device A13 where it is heated and its outer surface is dried.

Thereafter, the tubular body A10 is sent to an external surface hot-dip metal plating apparatus A14. In the outer surface molten metal plating apparatus A14, the tubular body A10 is immersed in a immersion section filled with pumped molten metal, and the entire outer surface is plated with molten metal. A hot-dip metal plating layer having a sound alloy layer is formed on the tubular body A10 soaked in the immersion section, and after excess hot-dip metal plating is removed in a wiping device (not shown), it becomes a hot-dip metal-plated steel pipe. . Thereafter, the tubular body A10 is cooled by the second cooling tank A15.

Then, the hot-dip metal-plated steel pipe is subjected to cold roll processing in a sizing device A16 in order to make the outer diameter a standard size. In this embodiment, cold rolling is a necessary step to make the molten metal plating layer relatively uniform in thickness in the circumferential direction. In other words, even if the molten metal plating layer immediately after being formed by the external molten metal plating equipment has an uneven thickness in the circumferential direction, the molten metal plating layer can be coated with molten metal through subsequent processes such as cold rolling. The plating layer can be made to have a relatively uniform thickness. As described above, in the present best mode, after the molten metal plating layer is formed by the external surface molten metal plating apparatus, sizing processing such as cold rolling is performed, and the molten metal plating formed by the molten metal plating process is It is desirable to employ a process that makes the layer relatively uniform in thickness (a process that makes the thickness distribution more uniform than immediately after forming the molten metal layer).

The hot-dip metal-plated steel pipe is cut into a predetermined length by a cutting device A17, resulting in a steel pipe product A18. The steel pipe products A18 are bundled and packed in a predetermined number, and sequentially arranged in an area waiting to be carried out.

<<<<Manufacturing information management system 100>>>>
Next, a manufacturing information management system 100 applicable to the above-described steel pipe manufacturing line (FIG. 10) will be described. FIG. 1 shows a manufacturing information management system 100 according to this embodiment. The manufacturing information management system 100 includes an information input device 110, a backend device (backend section) 120, a manufacturing information management device (manufacturing management information creation section) 130, and an information presentation device 140.

Details of the information processing performed by the information input device 110, the back-end device 120, the manufacturing information management device 130, and the information presentation device 140 will be described later, but in this embodiment, the information input device 110, the back-end device Information is transmitted in this order: 120, manufacturing information management device 130, and information presentation device 140. Information output from the information input device 110 (“manufacturing process information” to be described later) is collected by the back-end device 120.

However, the invention is not limited to this. For example, information output from the information input device 110 may be collected by the manufacturing information management device 130, and information processed by the manufacturing information management device 130 may be transmitted to the backend device 120. It's okay. In this case, the information processed by the backend device 120 is then sent to the manufacturing information management device 130, and the information created by the processing in the manufacturing information management device 130 (“manufacturing management information” to be described later) is sent to the manufacturing information management device 130. It is possible to send the information to the presentation device 140.

Alternatively, the present invention is not limited to this, and for example, the information output from the information input device 110 may be received by both the back end device 120 and the manufacturing information management device 130. In this case, the backend device 120 and the manufacturing information management device 130 can perform processing according to their respective purposes and use the information output from the information input device 110.

<<<Information input device 110>>>
The information input device 110 described above is a device for collecting information related to product manufacturing. In the following, information (information regarding product manufacturing) inputted into the manufacturing information management system 100 via the information input device 110 will be referred to as "manufacturing process information."

The manufacturing process information is information representing at least a part of various events that occur in the manufacturing of a product, and various types of manufacturing process information can be adopted. For example, information on materials for manufacturing the product, information on the product, etc. can be exemplified. Further, as information regarding materials and information regarding products, information on monitoring results (calculation results) of added value and costs (including costs, expenses, etc.) can be exemplified.

Examples of manufacturing process information include information related to lots of materials (which may also be products) and information related to the quality of the lots. Examples of information related to lots of materials (which may also be products) include information on lot symbols, which is lot tracking (also referred to as lot tracing) information that enables tracking of lots. Such lot tracking information functions as product identification information. Further, the product identification information may be information that allows identification of individual products (in this case, steel pipes), and such product identification information can also be used as manufacturing process information.

Examples of manufacturing process information include quality control information regarding materials and products. Further, as the manufacturing process information, information on condition management of materials and products can also be exemplified. The quality control information may be included in the condition management information, or the condition management information may be included in the quality control information.

Furthermore, as manufacturing process information, information related to monitoring and management of various machines and equipment that constitute the steel pipe manufacturing line (FIG. 10) can also be exemplified. In addition, examples of manufacturing process information include information related to product manufacturing and monitoring and management of the operation of a steel pipe manufacturing line.

The information input device 110 used to input this information includes various general information input devices. As the information input device 110, for example, a keyboard or mouse connected to computer equipment in the materials management department or manufacturing management department, a touch panel of a tablet terminal, a surveillance camera placed in each process of the manufacturing system, etc. can be used.

Further, on the steel pipe manufacturing line (FIG. 10) as described above, workers (operators who are involved in the manufacturing process) are appropriately assigned and placed. Workers wear headsets on their heads, which allow them to communicate with others. The information input device 110 also includes a headset worn by a worker. The headset used is one equipped with a microphone that can detect the voice of the worker. The microphone of the headset is a device included in the information input device 110.

As a specific usage example of the information input device 110, a situation where a headset is used will be described. In the assigned process, each worker may measure the product that has arrived, move the product using a crane (such as an overhead crane), touch the flowing product, or visually observe the product. Product measurement items include plate thickness, inner and outer diameters of steel pipes, length of steel pipes, and surface treatment thickness (plating thickness, etc.).

Product measurements may be carried out automatically while the product is flowing on the steel pipe production line, or may be carried out randomly by taking out a part of the product flowing on the steel pipe production line. In some cases, mechanical strength tests are conducted by random punching using a testing machine located in a corner of the factory.

Workers may also operate a control panel (also referred to as an "instrument panel" or "dashboard") for controlling equipment for the process for which they are responsible. Changeable items (parameters) that can be changed by operating the control panel include, for example, the conveyance speed (sometimes simply referred to as "speed") of the steel pipe manufacturing line (Fig. 10), welding output, and heating. Examples include temperature, zinc temperature, and pressure and amount of gas to be sent.

A single worker or a plurality of workers may be assigned to each process. Note that one worker may be in charge of multiple steps.

As described above, the worker wears a headset (150 in FIG. 11) equipped with a microphone. The headset 150 collects the voices of all workers through a microphone, which is a sound collecting device, and transmits the voice data (voice information) to a server device ( For example, it is sent to the backend device 120). The headset 150 is also equipped with a sounding device such as earphones or headphones. The headset 150 may also be equipped with earphones or headphones that utilize bone conduction.

The sound collected (picked up) by the microphone is now transmitted to the earphones and headphones provided in other headsets 150 via a communication network (represented by reference numeral CN in FIG. 11, which will be described later). ing. The worker can then listen to the voices uttered by other workers.

Here, it is also possible to set a rule in advance such that the worker calls out the name of the person with whom he/she wishes to converse, and then converses with the called party. It is also possible to distribute a controller to each worker, which has a selection button that allows the worker to select a conversation partner, so that the worker can talk to the selected party. In this case, multiple sets of workers can have a conversation at the same time.

Workers inspect products that are in the manufacturing process and products that have been manufactured using the inspection functions of the equipment on the steel pipe production line, as well as the inspection equipment located around the steel pipe production line or in a corner of the factory. Evaluations are made by visually inspecting the product, or by randomly picking up the product.

At this time, if an unusual situation is discovered with the product, information regarding the product's condition may be voiced. The contents of the worker's utterances are picked up by a microphone and collected as audio data. By collecting voice data of the workers in this manner, it becomes possible to aggregate contents such as conversations between the workers and comments of the workers in the server device (for example, the back-end device 120).

Further, even if no unusual circumstances are found in the product, the worker may sometimes mutter something that is not unusual. Even in such a case, it is possible to transmit the worker's voice data to the server device (for example, back-end device 120) and store it.

<<<Backend device 120>>>
Subsequently, a server device can be used as the backend device 120 described above. As the server device, as schematically shown in FIG. 13, a computer device including a control section 160, a storage section 162, a communication I/F (communication interface) section 164, etc. can be used. The back-end device 120 may be configured by one server device or a plurality of server devices with distributed functions. Further, various processes executed by the back-end device 120 may be executed in a distributed manner by one or more processors.

The storage unit 162 of the back-end device 120 may be a semiconductor memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory) that stores various information, a HDD (Hard Disk Drive), or an SSD (Solid State Drive). Non-volatile storage devices such as The storage unit 162 stores an operating system program, a driver program, an application program, data, etc. used for processing in a processor (here, included in the control unit 160). Furthermore, the storage unit 162 may be built into the server device or may be externally attached.

The backend device 120 includes a data backend section 122 and an analysis backend section 124. The data back end unit 122 and the analysis back end unit 124 may be configured by one computer device, or may be configured by separate computer devices. Furthermore, at least one of the data backend section 122 and the analysis backend section 124 may be configured by computer equipment that is distributed in a distributed manner.

The data backend unit 122 aggregates various manufacturing process information input via the information input device 110. In the data backend section 122, various types of manufacturing process information are assigned attributes, classified for each assigned attribute, and created into a database. From the information input device 110, manufacturing process information that has been generated is inputted moment by moment as time passes. Therefore, the amount of manufacturing process information stored in the data backend unit 122 increases as new information is generated.

For example, in a situation where a steel pipe manufacturing line is being continuously filmed or a worker's microphone input is being continuously recorded, the amount of video data (the amount of stored data) will gradually increase. In addition, in situations where shooting (e.g., still image shooting) is performed every certain period of time (e.g., 3 minutes or 6 minutes), or in situations where the microphone is turned on only when the worker utters sound at a volume higher than a certain level, etc. Every time manufacturing process information is generated, the amount of data (the amount of stored data) of the manufacturing process information increases.

The manufacturing process information collected in the data back end unit 122 is used for learning by AI (artificial intelligence) (AI learning) in the analysis back end unit 124. The analysis backend section 124 analyzes the interrelationships of the manufacturing process information aggregated by the data backend section 122. Various types of analysis contents can be considered by the analysis back-end unit 124.

Examples of the content of the analysis include the relationship between lot tracking information of the material (steel plate) set in the uncoiler A2 (FIG. 10) and information on the presence or absence of defects. Furthermore, the relationship between information on the conveyance speed and dimensions (width, length, thickness) of the steel plate and the presence or absence of defects can also be exemplified. Furthermore, examples include the relationship between information on pipe dimensions (outer diameter, inner diameter, thickness) and the presence or absence of a defect, and the relationship between the thickness of various platings and the presence or absence of a defect.

Furthermore, an example of a defect is that the difference between the actual measurement value and the target value exceeds an allowable range. Furthermore, an example of a defect may be that a worker visually recognizes that a product flowing on a production line is in a different state from the normal state (normal state). Another example is that a state different from the normal state (normal state) is detected from the photographed image through image processing.

When a problem occurs, for example, the problem is resolved by a worker. In this case, the details of the work performed by the worker are input via the information input device 110. The information to be entered includes the details of the problem, the countermeasures taken, whether the problem was resolved by the measures taken, and if not, what kind of problem remained and what remained. Examples of information such as what countermeasures were taken for the problem can be provided. Examples of the information to be input include data from a check sheet prepared in advance, text data explaining the contents of defects and countermeasures, and the like.

Note that the content of the analysis in the analysis backend unit 124 is not limited to information regarding defects, but may also include, for example, the relationship between information indicating that there is no difference from normal operation (normal operation) and other information. good.

As described above, the information input by the information input device 110 also includes the worker's voice data. While this voice data is stored as sound, it is converted into text using application software for voice-to-text conversion (text-to-speech (T2S) engine) and then stored. Such data conversion processing may be performed by either the data back end section 122 or the analysis back end section 124.

In addition to the various types of information included in the manufacturing process information (including the product identification information mentioned above), the collection of manufacturing process information includes information that makes it possible to identify the process in the steel pipe manufacturing line (process identification information), and time stamps ( (time information), etc. The process identification information can be information that can identify various information input devices 110 (input device identification information), or identification information of the worker who performed the input work (worker identification information).

By storing such process identification information in a storage device in association with manufacturing process information and creating a database, it is possible to determine which process the stored manufacturing process information belongs to. It becomes possible. Moreover, the above-mentioned time stamp becomes information indicating the time when the manufacturing process information is generated by being stored in association with the manufacturing process information. Therefore, the combination of the time stamp, process identification information, and manufacturing process information becomes information that can identify in which process and when the stored manufacturing process information occurred. By including lot tracking information (such as lot code information) in the manufacturing process information and adding a time stamp to each product, we can link various manufacturing process information, process identification information, etc. with the product. It becomes possible.

The manufacturing process information can be said to be information in which at least one attribute is the corresponding process or time of occurrence. Here, the time stamp in this embodiment includes information on year, month, and day, and information on hour, minute, and second. For this reason, by checking the correspondence between manufacturing process information and time stamps through information processing using computer equipment, etc., or by checking it manually, it is possible to check the correspondence between manufacturing process information and time stamps. It is possible to determine at what hour, minute, and second the occurrence occurred either immediately or afterwards (after the fact).

Taking voice data (including text-converted data) as an example, the voice data is stored along with information that makes it possible to identify the process on a steel pipe manufacturing line (process identification information) and a timestamp (time information). will be carried out. The process identification information can be, for example, information that can identify each headset 150 (headset identification information), or identification information of the worker who distributed the headset 150 (worker identification information). .

By checking the audio data associated with time stamps and process identification information, you can determine which voice was uttered by whom, in what process, and at what hour, minute, and second of what year, month, and day. It is possible to determine immediately or afterwards (after-the-fact) whether the information has been received.

A camera can also be provided in the headset 150 worn by the worker. By providing a camera in the headset 150, it becomes possible to take videos (which may be still images) of the process the worker is in charge of or the product related to the process. The image data acquired by the camera is also transmitted to the backend device 120 and stored in association with process identification information and time stamps. By doing this, it is possible to know immediately or later how the stored image data was recorded, by whom, in what year, month, day, hour, minute, and second. It can also be determined (after the fact).

Here, an example will be described in which the backend device 120 aggregates manufacturing process information from various information input devices 110 and associates the manufacturing process information with other information (time stamps, etc.). . However, the invention is not limited thereto, and, for example, the manufacturing information management device 130 described later may aggregate various types of manufacturing process information or associate manufacturing process information with other information (time stamps, etc.).

Further, various types of manufacturing process information may be input to both the back-end device 120 and the manufacturing information management device 130. In this case, the backend device 120 performs AI learning (described later) using various types of manufacturing process information and sends information based on learned results (learning result information such as teacher data) to the manufacturing information management device 130. It is possible to output.

In contrast, the manufacturing information management device 130 can associate manufacturing process information with other information (time stamps, etc.). Furthermore, the manufacturing information management device 130 can perform arithmetic processing using information on the results of AI learning in the back-end device 120 and the results of determination by the AI.

The manufacturing process information input to the back-end device 120 becomes a sample (AI sample) that is later processed by AI. In the analysis backend unit 124 of the backend device 120, AI learning (AI learning) is continuously performed using various manufacturing process information. For AI learning, for example, the details of the problem, the time of occurrence (including date and time), the countermeasures taken for the problem, and whether or not the problem was resolved by the taken countermeasure, and whether the problem was not resolved. Information such as what defects remain and what countermeasures were taken to deal with the remaining defects is continuously accumulated and analyzed.

For example, if a problem occurs in a certain process, what was the situation in other processes, and what countermeasures were taken for which process to resolve the problem? Information such as this is accumulated sequentially. Such AI learning may be performed by a plurality of computer devices connected via a communication network (symbol CN in FIG. 11, described later).

Various AI learning methods can be adopted depending on the manufacturing process information to be analyzed and the intended method. As an AI learning method, for example, it is also possible to employ deep learning in addition to statistical machine learning. Regarding machine learning, in addition to supervised learning and unsupervised learning based on statistics, reinforcement learning in which rewards (evaluation) are given can also be employed.

In supervised learning, training data is given as results or correct answers, and a regression model or classification model is constructed. Typical supervised learning analysis methods include regression analysis and decision trees. In regression analysis, the relationship between explained variables and explanatory variables is quantitatively analyzed, and predictions are made based on the analysis results. Decision trees learn classification criteria (boundaries) and classify data in unknown situations.

Unsupervised learning involves grouping data and summarizing information. Typical unsupervised learning analysis methods include the k-means method, association analysis, social network analysis, and principal component analysis. Among these, in the k-means method, samples with similar characteristics and trends are classified into several groups. In the association analysis, the frequency of simultaneous occurrences is calculated, and recommended countermeasures are derived from the history of countermeasures to resolve the problem. In social network analysis, for example, connections between workers in the event of a problem are analyzed based on workers' voice data converted into text. In principal component analysis, a large amount of collected information is summarized (reduced) into a low-dimensional space.

In the aforementioned reinforcement learning, actions and choices that yield rewards (evaluation) are learned through trial and error.

The aforementioned deep learning is based on neural networks. Of the three layers (input layer, intermediate layer, output layer) in the neural network, one layer may be the intermediate layer that performs weighting and transformation. Further, the intermediate layer may be made deeper by having two or more layers. Neural networks and deep learning will enable efficient image recognition, speech recognition, speech synthesis, text processing, translation, etc.

<<<Manufacturing information management device 130>>>
Next, the manufacturing information management device 130 will be explained. As the manufacturing information management device 130, a server device can be used like the back-end device 120. As the server device, as schematically shown in FIG. 14, a computer device including a control section 170, a storage section 172, a communication I/F (communication interface) section 174, etc. can be used. The manufacturing information management device 130 may be configured by one server device or a plurality of server devices with distributed functions. Furthermore, various processes executed by the manufacturing information management device 130 may be executed in a distributed manner by one or more processors.

As the storage unit 172 of the manufacturing information management device 130, a nonvolatile storage device including a semiconductor memory such as a ROM or RAM that stores various information, an HDD, or an SSD can be used. The storage unit 172 stores operating system programs, driver programs, application programs, data, and the like used for processing in a processor (here, included in the control unit 170). The program for manufacturing information management stored in the storage unit 172 of the manufacturing information management device 130 can be called a manufacturing information management program. Furthermore, the storage unit 172 may be built into the server device or may be externally attached.

As described above, when the manufacturing information management device 130 collects the information (manufacturing process information) output from the information input device 110, the association with the time stamp (and process identification information) is This is performed by the information management device 130. By doing so, it becomes easy to centrally manage information that associates manufacturing process information with time stamps and the like.

The manufacturing information management device 130 has navigation, communication, and report functions, and by performing these functions, it can selectively provide manufacturing management information to product stakeholders (described later). can. Manufacturing management information is real-time information created by integrating information on people, things, and money related to product manufacturing and supply using time information based on time stamps. .

"Integration" here refers to, for example, not only "generating a new piece of information" but also "merging (combining, associating) two or more things into one". It means to include. The navigation, communication, and report functions of the manufacturing information management device 130 and the details of the manufacturing management information will be described later.

Moreover, "real time" in this embodiment means, for example, a state in which certain information has occurred, a state in which information has just occurred, a state in which a plurality of pieces of information are synchronized using time information, and the like. In particular, information on people involved in the manufacturing process (person information), manufacturing equipment information (product information), and product information (money information) can be analyzed based on time information using time stamps. When we say that these pieces of information are integrated in real time, we mean that these pieces of information are synchronized based on time information.

Note that the back-end device 120 and the manufacturing information management device 130 described above are not server devices in different groups, but are server devices in the same group (such as those connected by a VPN (virtual private network)), or in the same server device. It is also possible to use it as a server device.
<<<Information presentation device 140>>>

Next, the information presentation device 140 will be explained. The information presentation device 140 outputs manufacturing management information created by the manufacturing information management device 130. The information presentation device 140 may be a mobile terminal (including a smartphone, a tablet terminal, etc.) owned by a worker on a steel pipe manufacturing line, or a mobile terminal (including a smartphone, tablet terminal, etc.) owned by a factory manager. Examples include:

In addition, the information presentation device (output section) 140 may be a monitor device for computer equipment installed in a factory, or a monitor device for computer equipment supplied to executives, representative directors, etc. of a company that owns a steel pipe manufacturing line (Fig. 10). Examples include mobile terminals and monitor devices owned by external parties (including partner companies, consultants, etc.) of the company that owns the equipment and the steel pipe manufacturing line (FIG. 10).

In this way, the information presentation device 140 can be used as a variety of mobile terminals used near the steel pipe production line, a monitor device used in a location away from the steel pipe production line, and a monitor device used in a remote location away from the factory. It also includes monitoring equipment. The information presentation device 140 also includes one that can display images (still images and videos) taken on the steel pipe manufacturing line (FIG. 10). Here, in the manufacturing information management system 100, people other than workers on the steel pipe manufacturing line are also related parties involved in steel pipe manufacturing. For this reason, these related parties including workers can be collectively referred to as "product related parties" or the like.

The information input device 110, the manufacturing information management device 130, and the information presentation device 140 can communicate directly or via a communication network CN as shown in FIG. Examples of the communication network CN include the Internet, a LAN, a WAN, a public telephone line, a base station, a mobile communication network, and those interconnected via a gateway (including a so-called cloud). Further, the information input device 110, the manufacturing information management device 130, and the information presentation device 140 have a communication I/F section (only the manufacturing information management device 130 is shown in FIG. 14). data communication according to a predetermined communication protocol.

<<<Processing by manufacturing information management device 130>>>
Next, various processes executed by the manufacturing information management device 130 described above will be explained. In a steel pipe manufacturing line as shown in FIG. 10, products are not always manufactured according to plan, and events such as various defects and troubles may occur. Various defects and troubles can occur, but one example is when the dimensions of the steel plate (width, length, thickness) or the dimensions of the steel pipe (outer diameter, inner diameter, thickness) are not within the allowable range. Examples include that the detected plating film thickness is not within the target value range, and that the photographed image is different from a normal image (a reference normal image).

These defects may be detected by various measuring devices or discovered by visual inspection by an operator. Furthermore, if a measuring device that performs image processing is used, for example, defects such as flaws, deformation, and foreign matter contamination may be discovered through image processing (comparison with normal images, etc.).

When a problem occurs, in conventional production management systems and production management methods, the worker who discovered the problem must identify or infer the process causing the problem and resolve the problem. There are many. In addition, workers may ask their superiors (their names vary depending on the organization, but there are superiors such as ``line manager'' or ``lead man'') for instructions regarding subsequent actions, or the superior may personally (Fig. 10) may be walked around and grasp the status of other processes.

Occasionally, the occurrence of a defect is manifested as a decrease in product yield, but in this case, after the decrease in yield becomes clear, the cause of the decrease in yield must be investigated ex post facto, and the process that causes it must be corrected. Improvements are being made.

However, with this conventional approach, it is difficult to understand the manufacturing process as a whole, and it is difficult for stakeholders who are responsible for the overall management of the manufacturing process (factory managers, factory managers, etc.) For corporate managers and others, it has sometimes been difficult to make accurate management and management decisions. In addition, process workers also had to take action or report to others whenever a defect was found, making it difficult to improve production efficiency.

Furthermore, records of defects are kept, the cause of the defect is identified in which process, and improvements are made in the relevant process. However, using such conventional methods, it is difficult to completely optimize the manufacturing management of steel pipes.

Therefore, in the manufacturing information management system 100 of this embodiment, the manufacturing information management device 130 is provided with navigation, communication, and report functions. Then, through the navigation, communication, and report functions, product related parties can access information on workers involved in product manufacturing (in this case, pipe manufacturing) (information on people involved in the manufacturing process), information on equipment (information on products), etc. (manufacturing equipment information) and product information (product information, which is money information), are synchronized and shared in real time as much as possible.

The information handled by the manufacturing information management device 130 is manufacturing process information supplied via the back-end device 120, as shown in FIG. The backend device 120 also continuously supplies information learned by AI (AI learning information), information judged by AI (AI judgment information), and the like.

As described above, when manufacturing process information is directly input from the information input device 110 to the manufacturing information management device 130, the backend device 120 only needs to input AI learning information and AI judgment information. , it is not necessary for the backend device 120 to input manufacturing process information to the manufacturing information management device 130.

As the manufacturing information management device 130 performs the navigation, communication, and report functions, various alerts (warnings) are issued to the person in charge, as shown in FIG. The person in charge refers to a person who is the target of an alert among those involved in these products, including workers. Various types of alerts are presented to product personnel by an information presentation device 140 owned by the product personnel.

Various types of alerts are issued in a manner that depends on the content and attributes to be presented (defect content and attributes, etc.), the recipient, and other circumstances. In this embodiment, an alert that is relatively mild is defined as a "progress alert," and an alert that is intermediate is defined as a "warning alert." Furthermore, severe alerts are designated as "warning alerts."

Further, for example, it is also possible to present information to the worker by voice, and to present information to other product personnel using computer equipment such as a tablet terminal or a PC (personal computer). Generally, a worker must immediately respond to a situation such as a malfunction, and may not have time to carefully check images and text. Therefore, presenting information by voice is effective because it allows information to be confirmed while taking countermeasures.

In response, other product stakeholders need to carefully check the images and text and consider countermeasures to prevent similar defects from occurring in the future. For this reason, it is effective to present information to product-related parties other than workers using images or text.

In this way, the manufacturing information management device 130 attempts to share information related to the operating status using the information presentation device 140 owned by product related parties. Information regarding the operating status can be shared within the factory, within the office, and between the factory and the office. Information can now be presented to product stakeholders at different times using different types of information presentation devices 140, so that information can be presented in accordance with attributes such as roles, positions, and responsibilities of product stakeholders. ing.

＜＜Navigation function＞＞
In the navigation function performed by the manufacturing information management device 130, functions such as a setup checker, status and sequence monitor, and virtual ANDON are performed by calculation processing for navigation, as shown in FIG.

<Setup checker function>
Among these, the setup checker function utilizes the information presentation device 140 to present information regarding the product to be manufactured next. Examples of the information presented include information such as requirements and plans for the quality of the next manufactured product and operational performance. Conventionally, this information has been printed on paper specifications (instructions), and the specifications have been distributed to related parties. For this reason, conventionally, it has not been possible to immediately respond to changes in this information.

Further, the information described in the specifications covers a wide variety of items, and the number of items may be around 50, for example. Furthermore, not all of the information written in the specifications is printed using computer equipment or printer equipment, but may be information added by hand by the person involved in the product who gives the instructions. There is also. In addition, it is not always possible for the target worker to reliably recognize the large amount of information written in the specifications or the information that is difficult to read, and the worker may continue to work while overlooking information. It's not impossible.

In response to such circumstances, as in the present embodiment, the manufacturing information management device 130 processes information regarding the quality of the plan and operational performance of the next product to be manufactured, and displays the information presentation device 140 such as a mobile terminal. By presenting the product information to the product personnel via the system, it becomes possible to selectively present the information described in the instructions to the target workers. This makes it easier for workers to recognize necessary information, and allows them to immediately respond to changes in plans. These pieces of information can be displayed by inputting information into the information presentation device 140 by a product person.

It is also possible to select information necessary for a person involved in a product and display only the necessary information (often a plurality of pieces) as individual icons on the information presentation device 140 of the person concerned with the product. be. In this case, for example, when a worker who has finished confirming information touches an icon of a task that has been confirmed, the information presentation device 140 changes the color of the touched icon to a predetermined color. It is also possible. Then, if all the icons displayed on the same screen change to the same color, the manufacturing information management device 130 can determine that the worker has confirmed all information. be.

Furthermore, if the color of the icon does not change even after a predetermined period of time has elapsed since the icon was displayed, it is also possible to output an alert image or sound. By doing this, it is possible to prevent the worker from proceeding with the work without overlooking information regarding the product to be manufactured next. The process, from presenting instructions to workers to responding to them, can be performed interactively, making it easy to ensure that instructions regarding necessary work are thoroughly followed and to monitor for omissions in work. It becomes like this.

<Status and sequence monitor function>
The status and sequence monitor function enables real-time monitoring of the operational status and progress of ongoing manufacturing. 2 to 5 show display examples on the information presentation device 140 when the function of the status and sequence monitor is activated.

2 to 5 show a state in which manufacturing management information is output to the tablet terminal 152. In the example in Figure 2 (time series x layout order), at the top of the table (column headings), some of the processes of the steel pipe manufacturing line (Figure 10) are extracted and arranged (layout). There is. Time information is arranged (layout) on the front side (row heading).

As the items for each process, "slit", "front", "band furnace", "pipe making", "steel pipe furnace", "cutting", and "binding" are extracted and displayed from the left end. Among these, "slits" are made by cutting the original material (wound steel plate) in the longitudinal direction to make it relatively narrower as a pre-process of coil A1 on the steel pipe production line (Figure 10) described above. It is a process. The "front" continuing on the right side corresponds to the process of the shot blasting apparatus A3 in the steel pipe production line (FIG. 10), and the "band furnace" corresponds to the process of the inner surface hot-dip metal plating apparatus A6.

Further, "pipe making" corresponds to the process of the forming device A8 and the welding device A9, and "steel tube furnace" corresponds to the process of the external surface molten metal plating device A14. "Cutting" corresponds to the process of the cutting device A17, and "binding" corresponds to the process of binding the steel pipe products A18.

The time information arranged in the row direction is displayed every 10 minutes in descending order from the top. In the example in Figure 2, the top row is "9:50-10:00", followed by "9:40-9:50", "9:30-9:40", and the bottom row is "9:50-10:00". It says "8:00-8:10". Regarding the time display, for example, "9:40 to 9:50" means 9:40:00 to 9:49:59, and "9:50 to 10:00" means 9:50. It is possible to set a display rule such as 00 seconds to 9:59:59.

In this way, in the example of FIG. 2, information for the selected process can be displayed every 10 minutes. For example, in a situation where no problem has occurred in each process, nothing is displayed in each time cell in each process. However, if some kind of malfunction occurs, the manufacturing information management device 130 displays a symbol or character indicating the occurrence of a malfunction in the cell at the corresponding time of the corresponding process based on the manufacturing process information and time information. Manufacturing management information is output so that the color of the corresponding cell changes (from white to yellow, etc.).

The combination of process information and time information as shown in FIG. 2 is displayed according to a selection operation by a person involved in the product. In other words, the information displayed on the information presentation device 140 (or the information outputted by voice) is information corresponding to the item (selected item) selected by the person involved in the product based on his or her own judgment. Various items can be selected by product personnel, but for example, each process in the steel pipe manufacturing line (Figure 10) and various parameters related to steel pipe manufacturing (transfer speed, temperature, pressure, plate thickness, Examples include various dimensions such as outer diameter and film thickness. Other changes or additions can be made in accordance with the requests of those involved in the product.

When presenting information such as the example in Figure 2 (time series x layout order), a product person may want to display the example in Figure 2 (time series x layout order). It is possible to operate (touch operation, etc.) the selection button of the selection item of ``. For example, when you operate a parameter selection button such as "speed", "temperature", or "pressure" on the steel pipe manufacturing line (Fig. 10), the status related to the parameter (speed value information, OK /NG information, etc.) may be displayed in the cell of the corresponding time. An example of the selection button is one displayed as a UI (user interface) on a touch panel. In addition to displaying the selection buttons, it is also possible to provide, for example, audio guidance. The types of selection buttons include, for example, "speed", "temperature", "pressure", "speed of process", "temperature of process", or , ``pressure of ~ process'', etc. can also be adopted. Here, "~" means an arbitrary process name or object name.

In addition, product personnel may not only perform operations for the purpose of displaying the example in Figure 2 (time series x layout order), but also operate selection buttons related to selection items without specifying a specific purpose. It is also possible to do so. For example, when you select an item with a comprehensive meaning such as "Status Confirmation", the manufacturing information management device 130 displays information based on information such as the attributes of people involved in the product and the operational status of the steel pipe manufacturing line. It is also possible to determine manufacturing management information and display the example shown in FIG. 2 (time series x layout order).

Further, when a person involved in the product performs an operation to start up the application software, information may be presented based on information transmitted from the back-end device 120. Alternatively, when a dedicated terminal is used as the information presentation device 140, the information may be presented based on the information transmitted from the backend device 120 when a person involved in the product performs an operation to turn on the power supply. The operations performed by the product person in these cases can also be said to fall under the category of operations for selecting items.

The information required by people involved in the product varies depending on the attributes such as the role, position, or responsibility of the person involved in the product. Therefore, appropriate information can be quickly provided by presenting different manufacturing management information based on information on the operating status of the steel pipe manufacturing line, etc., using information related to the attributes of people involved in the product.

The selection of information necessary for product personnel can be performed using, for example, the results of AI learning in the back-end device 120. Specifically, the analysis backend unit 124 uses past history information to determine the correspondence between information related to the attributes of people involved in the product and information related to the operational status of the steel pipe manufacturing line (the most frequently used information under the applicable conditions). (e.g., high-quality information) using various statistical techniques. In addition, in a situation where there is no abnormality in product manufacturing (normal situation), what values are the speeds of other processes and other parameters relative to a certain parameter (speed, etc.) in a certain process? It is possible for the backend device 120 to learn the correlation between parameters such as the following. Furthermore, even in situations where there is an abnormality in product manufacturing, it is possible to learn correlations between multiple parameters.

Upon receiving a request from the manufacturing information management device 130, the analysis backend unit 124 transmits the learned result information to the manufacturing information management device 130. The manufacturing information management device 130 extracts necessary information from the information collected via the information input device 110 based on the content transmitted from the analysis backend unit 124, and creates manufacturing management information. The manufacturing information management device 130 outputs information for displaying the created manufacturing management information on the information presentation device 140, for example, as shown in the example of FIG. The manufacturing information management device 130 may perform statistical processing on the information transmitted from the analysis backend unit 124 to extract necessary information.

Note that the information presented on the information presentation device 140 (including audio output) will differ depending on information such as the attributes of the person involved in the product, but the same information will be presented even if the attributes of the person involved in the product differ. There may be cases.

Here, the selection by the person involved in the product is not limited to the touch panel, and may be made via keyboard operation, microphone input, or the like. When using microphone input, the manufacturing information management device 130 converts the audio data into text, and selects items that are determined to correspond to (or approximate) text data.

Next, in the example in Figure 3 (time series x causal relationship x correlation), information on causality (causal information) and information on correlation (correlation information) for the selected selection item is displayed in chronological order. The screen configuration is shown. Causal information is information that is displayed as having causality as a result of causality calculation. For example, the causal information is obtained by converting information related to events such as malfunctions into mathematical expressions based on past history, and determining information that corresponds to the obtained mathematical expressions as causal information.

In the example in Figure 3, "information" represents information such as detected defects, and "data X" and "data Y" are determined to be causal to the event of "information". represents information. In the example of FIG. 3, "data X" is information that is determined to have a stronger causality with "information" than "data Y." The strength of causality may be determined, for example, by the amount of information that applies to a mathematical formula related to the "information" event. In FIG. 3, the display range of "data X" and "data Y" related to causality is shown by adding white double-headed arrows.

Correlation, on the other hand, is recognized for information that does not apply to the above-mentioned mathematical expression, but that applies to a mathematical expression that is approximated within a certain range. In the example of FIG. 3, information that is correlated with "information" (correlation information) can be displayed in cells of data α to data δ. Correlation information is information that is displayed as having correlation as a result of correlation calculation.

Specifically, if the item "yield" is selected as "information" by a product person, the equipment used to collect the information necessary to calculate the yield (sensors for detecting dimensions and film thickness, etc.) For example, the output values of are displayed as "data X" and "data Y," and other information (such as conveyance speed information) is displayed as data α to data δ. In FIG. 3, the display range of data α to data δ related to correlation is shown by adding white double-headed arrows. Furthermore, the correlation decreases in the order of data α, data β, data γ, and data δ.

The above-mentioned "data X" and "data Y" are information extracted from a lot of collected information depending on the situation. Then, "data X" and "data Y" may be information predicted by the person involved in the product, or information not anticipated by the person involved in the product may be extracted. This is because the information transmitted from the backend device 120 to the manufacturing information management device 130 is information determined by AI (AI determination information). Furthermore, due to the statistical processing performed by the manufacturing information management device 130, information that is not expected by product personnel may be displayed as "data X" or "data Y."

To specifically explain this, we will explain, for example, the process of manufacturing a product in a certain process (for example, any of the "front", "belt furnace", "pipe making", and "steel pipe furnace" processes). We focus on "velocity", "pressure", and "temperature" as parameters. Furthermore, in this process, when the speed of product conveyance is V1 (for example, 60 m/min), consider the pressure P1 and temperature T1 that are set for the gas being fed. Also, consider the pressure P2 and temperature T2 when the speed is V2 (for example, 100 m/min). It is assumed that the relationship between V1, P1, and T1 when the speed is V1, and the relationship between V2, P2, and T2 when the speed is V2 has been learned by AI in the backend device 120.

Note that the parameters listed here are just examples, and various parameters are involved. For example, parameters that can be stored from upstream to downstream, from the purchasing stage of raw materials to the shipping inspection of products, can be elements of information extraction. Furthermore, among a plurality of processes from upstream to downstream, even parameters of processes that are separated to some extent (one or more processes apart) can be targeted.

Furthermore, if the product manufacturing quality (presence or absence of defects) does not exceed a certain threshold, it is considered good (no defects, OK), and if it does not exceed the threshold, it is defective (defects, NG). shall be. Further, it is assumed that P1 and T1 satisfy a certain relational expression when the speed is V1, and this mathematical expression is also satisfied by V2, P2, and T2. Relational expressions for various situations such as these can be derived through AI learning. Furthermore, in order to set parameters so as to satisfy the relational expression, when the speed is changed from V1 to V2, it is necessary to change P1 to P2 and also change T1 to T2.

Then, for example, when a certain item is selected, the manufacturing information management device 130 performs calculations regarding the above-mentioned process using information (including formulas) transmitted through AI learning. For example, the manufacturing information management device 130 displays the name of the parameter with the largest calculation result value (such as "speed") in the "data X" cell, and displays the name of the parameter with the second largest calculation result value (such as "speed"). For example, "pressure") is displayed in the "data Y" cell. At this time, in the above example, the parameter of "temperature" is excluded from the targets of "data X" and "data Y." In other words, two types of information are extracted from among three or more types of information (in this case, parameters in a specific process) that are selected.

Furthermore, for the extracted "data Ru. These can be the AI judgment information in the backend device 120, in which multiple types (here, four types) of highly correlated information are displayed in order from the top.

Next, in the example of Fig. 4 (product order x layout order), the process is placed at the top of the table (column heading), which is similar to the example of Fig. 2 described above, but the process is placed at the top (row heading). ), lot symbols are arranged (layout) in order. In the example of FIG. 4, information regarding the relationship between product lots and processes can be presented to product personnel.

Next, in the example of Figure 5 (product order × causal relationship × correlation), the point that causality information (causal information) and correlation information (correlation information) for the selected selection item is displayed is shown in Figure 5. This is similar to the example in No. 3, but lot symbols (here, "#1001" to "#1012") are arranged on the front side (row heading). In the example of FIG. 5, information regarding the relationship between product lots and causality and correlation can be presented to product personnel.

By presenting information as illustrated in Figures 2 to 5, a certain product person can check the presented information and find out what time and minute each process is concerned with, and each process related to which product. You will be able to pick up the time periods and processes that interest you. Regarding the process of interest, causal information or information that is correlated with causal information is automatically selected and presented. Therefore, based on experience, those involved in the product can quickly and accurately deal with defects that have occurred or are likely to occur.

Such responses by product personnel can be made in a predictive manner not only in situations where a defect has occurred, but also in situations where a defect has not occurred. Furthermore, product personnel can, for example, change the threshold value for determining pass/fail based on the presented information. In addition, it becomes possible for other product personnel to notice and take action on points that are difficult for workers in the process that has caused a problem or in a process that could potentially become a problem to notice.

<Virtual ANDON function>
In the virtual ANDON function, the status or situation of each machine and equipment is displayed in real time. "ANDON" here refers to a generally known production status reporting system, but "Virtual ANDON" uses the information presentation device 140 to report the status or status of each machine and equipment related to product manufacturing. The status is presented to product stakeholders via time information with timestamps.

<<Communication function>>
Next, the communication function of the manufacturing information management device 130 will be explained. Communication functions include real-time alerts using a T2S (text-to-speech) engine and team talk recording functions using an S2T (speak-to-text) engine.

Among these, in the real-time alert function by the T2S engine, alarms (or warnings) of progress, troubles (including defects), and problems (trouble, defects, etc.) are generated by the T2S engine for each worker. Conveyed in real time via audio. Therefore, if a malfunction or the like occurs, the operator is immediately presented with information to that effect and the malfunction.

While workers are working, they are often doing some kind of work, such as monitoring or operating a control panel. For this reason, it can be assumed that when information is presented in text, the information may not be conveyed reliably. However, by presenting information by voice via the headset 150, it is possible to transmit information more reliably even when the worker is working.

In addition, with the function of recording team talk with S2T (speak to text), it is possible to have conversations (team talk) between workers in the operation team (predetermined team) in real time. It is. Furthermore, the content of the conversation at this time is recorded as audio, and the audio data is converted into text by the S2T engine and saved. At this time, information on the time when the conversation occurred and process identification information (process identification information) are also added to the text information. The process identification information may be replaced with the worker identification information, or may be added together with the worker identification information.

According to such a communication function, it becomes possible to issue an accurate alert to a target person. Furthermore, communication based on voice becomes possible, and deeper communication becomes possible than when only information that is not based on conversation is presented. Furthermore, by using information on voice exchanges for AI learning and mathematically determining the relationship with other manufacturing process information, worker identification information, time information, etc., we can objectively understand the relationship between voice and worker behavior. be able to determine the Then, it will be possible to provide an AI tool for manufacturing process control that continuously repeats such learning. Then, as will be described later (bottom right row of FIG. 9), it becomes possible to perform continuous process improvement (continuous process improvement) toward full automation through the fusion of humans and AI.

<<Report function>>
Next, the report function of the manufacturing information management device 130 will be explained. The report functions include the plan and actual report function, the alert + team talk report function, and the machine utilization report function.

The plan and actual report function provides gap analysis (information on analysis results) between the forecast and actual results for improvement in the next shift or role. The "next shift" here refers to a matter related to the worker's work system, and means that the work shift shifts to the next shift. In the next shift, workers may be replaced and monitored by different workers, or the same worker may move to another process.

The above-mentioned "next roll" means a coil (roll) that is newly set on the steel pipe manufacturing line as coil A1 (FIG. 10). The above-mentioned "forecast and actual" means the schedule (plan) and the actual result, and the "gap between the forecast and actual" means the difference (difference, ratio, etc.) between the schedule and the actual result. Then, when the work shift or role is changed, the "planned-actual gap" in the previous work shift or role is calculated, and the calculation results are evaluated.

Examples of the content of the evaluation include matters such as how much the planned achievement rate is and whether the planned achievement rate is within an acceptable range. In the plan and actual report function, the results of such evaluation are presented as analysis results to product stakeholders via the information presentation device 140. Such evaluation is also expressed as yield. Here, a work shift may be performed in the middle of one role.

The Alert + Team Talk Report feature provides a record of alerts for improvement on the next shift, the same shift, or the next role, along with audio or text information. The "alert records" referred to here are records of various alerts regarding malfunctions and the like that occurred before.

The Machine Utilization Report feature provides continuous usage data for machinery and equipment to continuously improve performance.

It becomes possible to provide an AI tool for manufacturing process control that uses manufacturing management information obtained through such a report function for AI learning and continuously repeats AI learning. Then, as will be described later (bottom right row of FIG. 9), it becomes possible to perform continuous process improvement (continuous process improvement) toward full automation through the fusion of humans and AI.

Furthermore, the above-mentioned information on people involved in the manufacturing process (information on people), information on manufacturing equipment (information on things), and product information (information on money) are information whose content and nature are related to people involved in the manufacturing process. The information is differentiated based on whether it is information related to manufacturing equipment, information related to products, or information related to products. Depending on the content and nature of the information, it may correspond to more than one of manufacturing process stakeholder information, manufacturing equipment information, and product information.

<<<Work procedure in manufacturing information management system 100>>>
FIG. 12 schematically shows a working procedure in the manufacturing information management system 100 as described above. First, various manufacturing process information is collected using the information input device 110 (step (S) 100). Subsequently, time information and process identification information are added to and associated with the collected manufacturing process information (S110). The collected information is then sequentially recorded and saved in the database (S120).

The collected manufacturing process information is used for AI learning in the backend device 120 (S130). In AI learning, an appropriate learning method is adopted in consideration of factors such as the nature of manufacturing process information and the content of information that can be provided. Then, the results of statistical analysis and classification according to the nature and content of the information are sequentially accumulated.

When some kind of defect is discovered in the product, or when an event that requires status confirmation occurs, a person involved in the product selects an item (S140). The results of the item selection are then transmitted to the manufacturing information management device 130, which creates manufacturing management information according to the selected item, and presents information to the information presentation device 140 of the product person who selected the selected item. Send manufacturing control information to. Then, the information presentation device 140 presents information according to the manufacturing management information (S160).

(3) Also, associate at least one of the manufacturing process related person information, the manufacturing equipment information, and the product information with product identification information (such as lot code information) that enables the product to be identified. Accordingly, it is possible to output the manufacturing management information (information on "product order x layout order" in the example of FIG. 4, information on "product order x causality x correlation" in the example of FIG. 5, etc.).
(4) Also, causal information calculated as having causality with respect to the item selected by the product person (information displayed as having causality as a result of causality calculation, etc.); The manufacturing control information is combined with the correlation information calculated as having a correlation with the causal information (information displayed as having a correlation as a result of the correlation calculation), and is associated with the time information. It is possible to output.
(5) Also, the manufacturing process of the product is a manufacturing process of steel pipes,
The manufacturing process includes at least a step of using an uncoiler, a step of using a forming device, a step of using an inner surface molten metal plating device, a step of using a welding device, a step of using a cutting device, and a step of using an outer surface molten metal plating device.

Step (S110),
A third step (S140 to S160) of outputting the manufacturing management information according to selection items selected by product personnel including the manufacturing process personnel.
(7) In addition, the manufacturing information management device 130 uses the manufacturing information management program to collect manufacturing process personnel information related to manufacturing process personnel assigned to the product manufacturing process,
Manufacturing equipment information related to manufacturing equipment used to manufacture the product;
Processing that enables input of manufacturing process information including product information regarding the product;

and outputting the manufacturing management information according to selection items selected by product personnel including the manufacturing process personnel.

For these reasons, according to the manufacturing information management system 100 of this embodiment, information on workers involved in product manufacturing (information on people involved in the manufacturing process, which is information on people), information on equipment (things), etc. (manufacturing equipment information) and product information (product information, which is money information) are linked and integrated via time information. Information on people, goods, and money can then be synchronized in real time and shared among product stakeholders. As shown in the upper right corner of Figure 9, it becomes possible to collect and integrate comprehensive data on people, goods, and money in real time.

Also, based on the information collected by the information input device 110, manufacturing management information is created in the manufacturing information management device 130 and presented to product related parties via the information presentation device 140, so that information on the situation occurring at that time is displayed. is immediately provided as feedback to product stakeholders. The alert output by the manufacturing information management device 130 becomes a real-time instruction.

Furthermore, since the backend device 120 sends the content learned by AI using various process information to the manufacturing information management device 130, the manufacturing information management device 130 can improve It is possible to output optimal manufacturing control information. As a result, it becomes possible to present information related to past events when product personnel take action for overall optimization. As shown in the middle right row of FIG. 9, standard optimization (optimization of work standards) is possible with real-time machine deep learning support.

According to the manufacturing information management system 100 of the present embodiment, a factory manager, a business manager, or a person related to product manufacturing who is a person other than the workers (persons involved in the manufacturing process) placed on the steel pipe manufacturing line Even third parties and other related parties (product related parties) will be able to find the cause and solution of a problem in a short time.

The manufacturing information management device 130 can provide manufacturing management information in which navigation and communication are correlated by exhibiting the navigation function and the communication function. From these facts, as shown in the lower right part of FIG. 9, it becomes possible to perform continuous process improvement (continuous process improvement) toward full automation through the fusion of humans and AI.

Furthermore, information on the actions taken by product personnel, including workers, based on the information presented to them will also be continuously accumulated. Therefore, it becomes possible to provide an AI tool for manufacturing process control. Further, it is possible to provide a manufacturing information management device 130 and a manufacturing information management system 100 in which manufacturing process control is fully automated through AI tools and can realize more advanced overall optimization through continuous improvement.

Furthermore, since continuous process improvement utilizes worker information (voice data, etc.), it is possible to provide a unique development environment that involves the steel pipe manufacturing site.

To give a specific example, let's assume that a steel pipe marked with certain product identification information is found to have manufacturing defects (for example, abnormal scratches) after the pipe is completed. . In this case, by searching the database for the product identification information of the steel pipe, information on the wall thickness of the steel plate, information on the external shape of the steel pipe, and voice information of the worker, which are associated with the product identification information of the steel pipe, are output. Product personnel check the output results. By doing so, even those involved in the product other than the workers can accurately investigate the cause of manufacturing defects in a short time.

In addition, for example, if an abnormal value occurs in any of the measurement results in the manufacturing process of steel pipes, the measurement result can be changed by outputting the conditions and audio information associated with the measurement result based on the measurement result. It becomes possible to investigate the cause of abnormal values. Specifically, if the measurement result of the internal plating post-board thickness measuring device that measures the board thickness after internal plating is an abnormal value, the internal plating conditions of the internal plating device and the worker in charge of the internal plating processing device will be You can check the audio information by playing it (or displaying it in text form or outputting it as audio) to investigate the cause of the abnormal inner plating value.

Further, the manufacturing information management system 100 of this embodiment can also be explained as follows. For example, by having product personnel outside the factory check the images taken by various cameras, it is possible to create an environment as if they were conducting a factory patrol from a remote location (remote factory patrol). . This makes it possible to easily carry out (joint) factory inspections by the manufacturing site, the engineers who manage the manufacturing process, and the SE (system engineer) who developed the control system for the manufacturing process. .

In addition, by presenting information including layout order information as in the examples in Figures 2 and 4, it is possible to identify the process through which the product with the event to be confirmed was manufactured. can be understood at a glance. If the length from the upper process to the lower process on the steel pipe manufacturing line (Figure 10) is, for example, about 100 m, then what is the relationship between the product in which the event that should be confirmed and the steel pipe manufacturing line, which is about 100 m long? Information such as whether the process is affecting the process can be recognized at a glance.

Regarding the input of selection items, it is possible to consider selection items that take into account the flow of products in the steel pipe manufacturing line. Furthermore, by inputting a plurality of selection items for processes corresponding to the flow of products, it is possible to present results that can be calculated as the cause of the event to be confirmed. Furthermore, it is also possible to present information about the processes before and after the process that is the cause of the phenomenon to be confirmed.

Furthermore, by adding a time stamp (time information) to the manufacturing process information for each roll, it is possible to present information that links many other pieces of information and products. Furthermore, by providing time-series time information, it is also possible to refer to logs every 3 minutes or every 6 minutes to check changes in conveyance speed, temperature, etc., for example.

It also becomes possible for the upper process to understand what is happening in the lower process. It becomes possible for workers and product-related parties other than workers to connect through real-time information. It is also possible to store information indicating the quality of the product. Not only the situation where the defect occurred, but also the manufacturing process information for the situation where the defect did not occur will be recorded.

Equipment information (manufacturing equipment information that is product information) can be used for equipment maintenance planning. Regarding product information (product information that is money information), for example, if the target is to produce 12 tons of products and the actual production is 8 tons, the information presentation device 140 will display the calculation result of 8/12. By displaying this information, those involved in the product can understand the situation as if the economic value of 8/12 is being obtained.

Regarding the selection of selection items, for example, if you touch the UI whose coloring is inverted with your finger, the current value of information classified as related will be output to the information presentation device 140 of the person involved in the product who performed the operation. It becomes possible to do things like

Furthermore, for example, it is possible to include an overseas engineer as a person involved in the product, transmit manufacturing management information to the information presentation device 140 of the engineer, and request information for overall optimization from the engineer.

Then, the people (workers) who are actually working, the manufacturing equipment, and the products are linked by the manufacturing information management system 100, and each person involved in the product can perform overall optimization on a time-by-time or product-by-product basis. This may make it easier to take actions such as course corrections toward the future. Further, by performing AI learning and using the results of the AI learning to output manufacturing management information, it is possible to provide the manufacturing information management system 100 in which experience is accumulated over time.

Furthermore, when an image taken with a camera is sent to the information presentation device 140 of a person involved in the product other than the worker (for example, an engineer located in a remote location from the factory), due to recent improvements in resolution, the worker It is also possible for someone involved in the product other than the worker to notice a phenomenon that was not noticed visually, and for that person to take action for overall optimization.

Further, the present invention is not limited to the manufacture of steel pipes, but can be applied to the manufacture of various products obtained by performing secondary processing on products that have been primarily processed from raw materials. Furthermore, the present invention is applicable not only to line production, but also to, for example, cell production.

<<<Work status reporting function>>>
It is also possible to provide the manufacturing information management system 100 as described above with a work status reporting function as described below. As for the work status reporting function, in the above-mentioned <Setup Checker Function> section, for example, when a worker who has finished checking information touches the icon of the work that has been checked, the information presentation device 140 An example of changing the coloring of an icon to a predetermined color has been described. Furthermore, it was also explained that, through such a function, it is possible to easily monitor for omissions in work.

Here, a more specific example of such a work status reporting function (work status reporting function) will be explained. For example, icons that can be operated by the worker are displayed on the worker's information presentation device 140 (FIG. 16). As the information presentation device 140 here, a mobile terminal (particularly a smartphone) owned by a worker placed on a steel pipe manufacturing line can be exemplified.

It is assumed that a worker is assigned multiple tasks that must be completed within a certain period of time. Examples of the fixed period include half a day, one day, two to five days, or one week. The worker handles the assigned work within the above-mentioned fixed period depending on the worker's arrangement and the content of the work.

A situation is assumed in which multiple workers are placed apart from each other. There may also be situations in which each worker is unable to accurately grasp the progress status of each other's work, or is unable to visually recognize other workers at all.

FIG. 15(a) schematically shows an example of a combination of worker arrangement and work name in the steel pipe manufacturing line as shown in FIG. 10. "Section" in FIG. 15(a) means the arrangement of workers, and "item" means the name of the work.

“A1”, “A6”, “A9”, “A14”, and “A17” in the “section” column in the example of FIG. This corresponds to a hot-dip metal plating device A6, a welding device A9, a hot-dip metal plating device A14 for external surfaces, and a cutting device A17. Here, the "sections" are not limited to "A1", "A6", "A9", "A14", and "A17", but may be other steps. Further, the present invention is not limited to the steel pipe manufacturing line shown in FIG. 10, and may be a steel pipe manufacturing line with another configuration or a manufacturing line other than steel pipes.

In the example of FIG. 15(a), the sections "A1", "A6", "A9", "A14", and "A17" are "α", "β", "γ", and "δ", respectively. ” and “ε” symbols. The "item" in the example of FIG. 15(a) is represented by a numerical value of "1" to "6". In this embodiment, in order to avoid complicating the explanation, specific work names are not described, and each work name is distinguished by a numerical value.

In the example of FIG. 15(a), items (work) "1", "3", and "4" are determined to be performed in the section "α". In the example of FIG. 15(a), the combinations of the section "α" and the items "1", "3", and "4" are "1-α", "3-α", and " 4-α”.

These combinations mean work "1", work "3", and work "4" in the section "α". In other words, the work "1-α", the work "3-α", and the work "4-α" are the work "1", the work "3", and the work "4-α" in the "α" section. It means each of the "4" tasks.

Also, in the "β" section, it is decided that items "1", "2", and "3" will be performed, and in the "γ" section, the items "1" and "3" will be performed. The item is determined to be done. Furthermore, in the section "δ", it is determined that item "3" is performed, and in the section "ε", it is determined that items "1" and "3" are performed.

In the example of FIG. 15(a), the items "1", "2", and "3" in the "β" section are "1-β", "2-β", and "3-β". ”. Furthermore, items “1” and “3” in the “γ” section are expressed as “1-γ” and “3-γ”. Also, the item “3” in the “δ” section is expressed as “3-δ”, and the items “1” and “3” in the “ε” section are expressed as “1-ε”. , and "3-ε".

Here, for example, "1-α", "3-α", and "4-α" are performed in the section "α" where the items "1", "3", and "4" are It also represents that. Similarly, for "1-β", "2-β", and "3-β", items "1", "2", and "3" may be performed in the "β" section. represents. The same applies to the other sections "γ", "δ", and "ε".

Furthermore, in the example of FIG. 15(a), "-" indicates that there is no corresponding "item" in that section.

FIG. 16 shows an example of display content on the display screen 142 of the information presentation device 140 carried by the worker. As shown in FIG. 16, an image of a work progress input page 180 is displayed on the display screen 142. The display screen 142 of the information presentation device 140 is equipped with a touch panel structure. The worker can perform various general operations such as tapping, swiping (sliding), flicking, etc. on the display screen 142 of the information presentation device 140 with his or her fingers.

The display content on the information presentation device 140 allows each worker to input their own situation. The display screen 142 displays the name of the work to be performed (work name, item) in the section assigned to the worker carrying the information presentation device 140.

In the example of FIG. 16, a display screen 142 on the information presentation device 140 of a worker assigned to section α is shown, and the display screen 142 includes "Item 1", "Item 3", and "Item 4". ' icon is displayed. "Item 1", "Item 3", and "Item 4" in the example of FIG. 16 are "1-α", "3-α", and "4-α" in the example of FIG. 15(a). It corresponds to

In FIG. 17(a), a worker carrying the information presentation device 140 (herein referred to as "smartphone 1") in the example of FIG. This shows that the operations ``α'' and ``4-α'' correspond to each other. This worker is in charge of only the "α" section.

One worker may be in charge of multiple "sections." FIG. 17(b) shows the items of the worker in charge of the "β" and "γ" sections. The workers in charge of the "β" and "γ" sections are required to work on "1-β", "1-γ", "2-β", "3-β", and "3-γ". is assigned.

FIG. 17(c) shows the items of the worker in charge of the "α", "δ", and "ε" sections. The workers in charge of the sections "α", "δ", and "ε" have sections "1-α", "1-ε", "3-α", "3-δ", " The tasks ``3-ε'' and ``4-α'' are assigned.

For example, the workers assigned the tasks "1-α", "3-α", and "4-α" (the worker carrying the information presentation device 140 (smartphone 1) in FIG. 17(a)) is selected by tapping any one of the icons 182, 184, and 186 for "Item 1," "Item 3," and "Item 4" on the display screen 142 in FIG. 16.

By tapping the icon, the operator inputs information, and the input information is reflected on a confirmation screen 250 as shown in FIG. 19, for example. Although details will be described later, the confirmation screen 250 is displayed on the information presentation device 140 (which may be a tablet terminal 152, etc.) used by a group supervisor (which may be a factory manager, factory manager, etc.). Ru. On the confirmation screen 250, the display changes according to the progress status of each worker, and the work status is notified.

Information communication between the worker's information presentation device 140 and the supervisor's information presentation device 140 can be performed directly (P2P (peer-to-peer)) and/or via the communication network CN (FIG. 11).

<<Work progress status input page 180>>
What is shown in FIG. 16 is an initial screen that is displayed after each worker operates and logs in to his or her own information presentation device 140. On the initial screen in the example of FIG. 16, three icons, a first icon 182, a second icon 184, and a third icon 186, are displayed vertically side by side.

For example, in the case of the worker shown in Figure 17(a) (the worker using smartphone 1), there are three assigned tasks: "1-α", "3-α", and "4-α". Therefore, the first icon 182, second icon 184, and third icon 186 are icons corresponding to "1-α", "3-α", and "4-α".

Furthermore, for example, in the case of the worker shown in FIG. 17(b) (the worker using smartphone 2), the assigned tasks are "1-β", "1-γ", "2-β", and "3-β". Although not shown, five icons are vertically arranged and displayed on the display screen 142.

In this way, when four or more icons are displayed, the content displayed on the display screen 142 is moved downward on the work progress status input page 180 by the worker, for example, swiping upward. do. By swiping the initial screen shown in FIG. 18, the display contents scroll upward, and the fourth and subsequent icons (not shown) appear.

Furthermore, for example, in the case of the worker shown in FIG. 17(c) (the worker using smartphone 3), the assigned tasks are "1-α", "1-ε", "3-α", "3- There are six types: ``δ'', ``3-ε'', and ``4-α''. Therefore, although not shown, six icons are displayed vertically on the display screen 142. Then, by swiping the display screen 142, the displayed content is scrolled upward, and the fourth and subsequent icons (not shown) appear.

In addition, below, the function of each icon will be explained using the worker's display screen 142 shown in FIG. 17(a) as an example.

The three icons 182, 184, and 186 shown in the example of FIG. 16 have the same size. For example, the size of the icons 182, 184, and 186 is determined by the size of the three icons (first icon 182 to third icon 186) on the initial screen (FIG. 16), the total area of the display screen 142 (total displayable area). It is set so that 70% or more (more preferably 80% or more) of the area is occupied.

If four or more tasks are assigned, the sizes of the fourth and subsequent icons displayed by swiping are also set to be the same as the three initially displayed icons.

Each icon is written with a character string indicating the name of the work (item) to be performed by the corresponding worker. In the example of FIG. 16, the names "Item 1," "Item 3," and "Item 4" are displayed on each of the icons 182, 184, and 186 without using specific work names. Further, in the example of FIG. 16, the first icon 182 to the third icon 186 are all displayed in grayscale.

<<First icon corresponding page 190>>
For example, when the worker taps the first icon 182 corresponding to "Item 1" and selects the first icon 182, a first icon corresponding page 190 is displayed as shown in FIG. 18(a). The first icon corresponding page 190 is a page displayed in response to an operation on the first icon 182 shown in FIG. 16.

Although not shown, if the second icon 184 corresponding to "Item 3" is selected, the corresponding second icon corresponding page is displayed, and if the third icon 186 corresponding to "Item 4" is selected, the corresponding second icon corresponding page is displayed. , the corresponding third icon corresponding page is displayed. If icons after the fourth icon are provided, the page corresponding to the selected icon is displayed as each icon is selected.

On the first icon corresponding page 190 shown in FIG. 18(a), three icons, a 1-1 icon 192, a 1-2 icon 194, and a 1-3 icon 196, are displayed vertically. . These three icons 192, 194, and 196 have the same size. The size of the icons 192, 194, and 196 is, for example, 50% or more of the total area of the display screen 142 (total displayable area) due to the three icons (1-1 icon 192 to 1-3 icon 196). (more preferably 60% or more).

In the example of FIG. 18A, the 1-1 icon 192 displays the words "Completed," and the 1-2 icon 194 displays the words "In Progress." The characters "Problem" are displayed on the 1st-3rd icon 196. Above the 1-1 icon 192 at the top, a title is displayed (in this case, the characters ``Item 1'' are displayed).

The 1-1st icon 192 to the 1-3rd icon 196 are color-coded and painted differently. In the example of FIG. 18(a), the 1-1 icon 192 is green (indicated by a medium-density gray scale), and the 1-2 icon 194 is yellow (indicated by a low-density gray scale). The first to third icons 196 are colored red (indicated by a high-density gray scale).

The 1-1 icon 192 is used to confirm that it has been completed (which may also mean "achieved" or "reached"), and the 1-2 icon 194 is used to confirm that it is in progress. Used for confirmation. The 1st-3rd icon 196 is used to confirm that a problem has occurred. In other words, the 1-1 icon 192 to the 1-3 icon 196 indicate the progress of the work related to the item of the first icon 182 (here, "Item 1") on the work progress input page 180 shown in FIG. This is the icon that indicates.

When the work corresponding to the first icon 182 (here, "Item 1") is completed, the worker who performed the work can select the 1-1 icon on the first icon corresponding page 190 in FIG. 18(a). Tap 192. When the 1-1 icon 192 is tapped, the display on the display screen 142 shifts to a work progress input page 180, as shown in FIG. 18(b).

On the work progress status input page 180, the first icon 182 is displayed in reverse video in the same color as the 1-1 icon 192 (here, green). By making the coloring of the icon common to the 1-1 icon 192, the 1-1 icon 192, which means "Completed", can be operated on the 1-1 icon corresponding page 190 (here, the "item 1" page). This is reflected in the first icon 182. Then, by changing the coloring of the first icon 182 to the same coloring as the 1-1 icon 192, the work corresponding to the first icon 182 (here, "Item 1") is completed. The meaning is expressed.

Further, when the work related to the first icon 182 (here, "Item 1") is in the middle state ("In Progress" state), the worker who is working on the work related to the first icon 182 in FIG. 18(a) On the corresponding page 190, tap the 1st-2nd icon 194. Examples of situations in which the 1-2 icon 194 is tapped include situations in which the work is "Completed" or in which the task does not fall under "Problem," which will be described later.

When the 1-2nd icon 194 is tapped, the display on the display screen 142 shifts to a work progress status input page 180, as shown in FIG. 18(c). On the work progress status input page 180, the first icon 182 is displayed in reverse video in the same color as the first-second icon 194 (yellow here). As a result, the first icon 182 indicates that the work corresponding to the first icon 182 (here, "Item 1") is in the middle of the process.

Similarly, if the work corresponding to the first icon 182 (here, "Item 1") is in a state where some kind of problem has occurred ("Problem" state), the worker who is working on it 18(a), tap the 1st-3rd icon 196 on the first icon corresponding page 190. When the 1-3rd icon 196 is tapped, the display on the display screen 142 shifts to a work progress status input page 180, as shown in FIG. 18(d).

On the work progress status input page 180, the first icon 182 is displayed in reverse video in the same color as the first to third icons 196 (here, red). This gives the first icon 182 the meaning that the work corresponding to the first icon 182 (here, "item 1") is in a state where a problem has occurred.

When the "Completed", "In Progress", or "Problem" icon is selected on the page corresponding to the icon after the second icon 184 (icon compatible page), the icon after the second icon 184 is also selected. Changes in coloring are reflected.

Although not shown, the work progress status input page 180 displays the relationship between the number of icons marked "Completed" and the number of tasks to be performed (ratio of number of completed tasks). For example, in the case of the worker using smartphone 1 shown in FIG. "1/3" is displayed in a predetermined area. If two tasks are marked "Completed," "2/3" will be displayed, and if all three tasks are "Completed," "3/3" will be displayed. be exposed.

<<Confirmation screen 250>>
FIG. 19 shows an example of the confirmation screen 250. The confirmation screen 250 is displayed on the information presentation device 140 (which may be a tablet terminal 152, etc.) used by a group supervisor (which may be a factory manager, factory manager, etc.).

The confirmation screen 250 displays an “Overview” sheet showing an overview of the manufacturing line. The confirmation screen 250 shown in FIG. 19 is provided with a first information column 252 to a twelfth information column 274. In the example shown in FIG. 19, the twelfth information column 274 is configured in a matrix, and sections "α" to "ε" are assigned to each column of the matrix. Furthermore, items “1” to “6” are assigned to each row of the matrix. The intersection of each section and each item is divided into cells, and a check mark 302 is displayed in gray scale in each cell.

A check mark 302 is displayed in a cell where there is an assignment between a section and an item, and a cell without an assignment is blank without a check mark 302.

FIG. 15(b) shows the contents of the twelfth information column 274 in FIG. The sections and items in FIG. 15(b) also correspond to the sections and items in the diagram shown in FIG. 15(a).

For example, if the 1-1 icon 192 meaning "Completed" is operated on the first icon corresponding page 190 (here, the page for "Item 1") shown in FIG. As shown in b), the check mark 302 in the cell corresponding to item 1 in section "α" changes from gray scale to the same color as the 1-1 icon 192 (here, green).

In other words, by inputting information that the work corresponding to the first icon 182 in FIG. 16 (here, "Item 1") is in the middle of the process, the check mark 302 corresponding to "1-α" is colored. The check mark 302 is given the meaning that the work corresponding to the first icon 182 (here, "item 1") is in progress.

Similarly, when the 1st-3rd icon 196 indicating a problem occurrence state ("Problem") is operated on the first icon corresponding page 190 (here, the "Item 1" page) shown in FIG. 18(a). , the check mark 302 corresponding to “1-α” changes to the same color as the 1-3 icon 196 (red here, not shown). The check mark 302 is given the meaning that the work corresponding to the first icon 182 (here, "Check state") is in a problem state.

On the confirmation screen 250, the supervisor confirms the coloring of the check mark 302 corresponding to "1-α" and determines whether the work corresponding to the first icon 182 (here, "Item 1") is in a completed state, in progress, or has a problem. The state of development can be perceived by the difference in coloring. In this way, the operator's operations are reflected on the information presentation device 140, allowing the supervisor to grasp the work status.

<<Operation on second icon 184 or third icon 186>>
Regarding the second icon 184 or the third icon 186 shown in FIG. 16, as described above, a page corresponding to each icon (second icon corresponding page or third icon corresponding page, not shown) is provided. ing. When either the second icon 184 or the third icon 186 is tapped, a transition to the corresponding page is performed.

On the corresponding page at the migration destination (not shown), icons (here, "Completed", The icons for "In Progress" and "Problem" are displayed using the same image data as for "Item 1". When the worker taps these icons according to the work status, the tapping is reflected in the coloring of the second icon 184 or the third icon 186 shown in the icon of the corresponding work (FIG. 16).

On the confirmation screen (confirmation screen 250 referring to FIGS. 19 and 20), an icon (here In this case, the coloring of the icons (“Completed”, “In Progress”, and “Problem”) is reflected.

In addition, after moving to the corresponding page for the second icon 184 or the third icon 186, the status is once completed (“Completed”), in progress (“In progress”), or a problem has occurred (“Problem”). If you operate a different icon after operating an icon, and then operate another icon after leaving the current situation (or due to a change in the situation), the second icon will be displayed according to the most recent (latest) operated icon. The coloring of the icons 184 to 182 of the fourth icon 188 also changes.

<<Change in coloring of check mark 302 on confirmation screen 250>>
The coloring of the check mark 302 on the confirmation screen 250 reflects the most recent operation by the operator. Even when multiple workers are in charge of the same work, the most recent operation by the worker is reflected. In addition, in FIG. 20, only the check mark 302 corresponding to the task "1-α" is displayed in green, which means "Completed," but each of the other tasks is also displayed in a color according to the input situation. Changes to If "Completed" is selected for all tasks, all check marks 302 are displayed in green.

According to the manufacturing information management system 100 of this embodiment, as explained using FIGS. 15 to 20, it is possible to have a more concrete work status reporting function. Furthermore, since the manufacturing information management system 100 has a work status reporting function, supervisors can quickly and accurately grasp the situation no matter how the work load is assigned to a given work. I can do it.

Therefore, even if flexible responses are made at the work site depending on the members and work situation at the time, supervisors can grasp the work progress without having to make verbal or written reports to the supervisor. can do. As a result, it is possible to carry out mountain collapse (smoothing the work load) that suits the situation without any unreasonableness or waste. Furthermore, even if the worker is left in charge of how to proceed with the work, the supervisor can grasp the progress of the work in real time.

In addition, by providing the manufacturing information management system 100 with a work status reporting function, when any worker presses an icon on an icon-compatible page (such as FIG. 18(a)), the manufacturing information management system 100 can be The information can be reflected on the information presentation device 140 of the worker. Additionally, if the same task is assigned to multiple workers, the most recent operation will be reflected in the icons of the duplicated tasks (for example, the first icon 182 to the third icon 186) or the check mark 302. can be taken as a thing. Furthermore, in the manufacturing information management system 100, the information presentation device 140 of other workers can be updated by one worker's operation, and the work can be shared within the group while sharing information.

The operations performed by the worker on the information presentation device 140 can be limited to specific operations such as swiping and tapping. As a result, the types of work performed on the information presentation device 140 can be reduced and optimized. As a result, it is possible to provide a manufacturing information management system 100 that minimizes impossibility and waste.

Workers can complete tasks according to the situation while checking their own job tickets, and supervisors can grasp the status and progress of each task by checking the status of job tickets being returned.

<<Other embodiments related to work progress input page 180>>
FIG. 21 shows another embodiment of the work progress input page 180. In the example of FIG. 16, a first icon 182, a second icon 184, and a third icon 186 are arranged vertically at equal intervals on the display screen 142, and these icons 182, 184, and 186 have "1- The tasks ``α'', ``3-α'', and ``4-α'' were associated with each other. On the other hand, the icons may be arranged as shown in FIG. 21(a).

FIG. 21A schematically shows an example of the display screen 142 of the information presentation device 140 (smartphone 1) according to the example of FIG. 16. Here, although FIGS. 17(a) to (c) show the relationship between each information presentation device 140 (smartphones 1 to 3) and the assigned tasks, FIGS. 21(a) (and ( b) and (c)) schematically show the arrangement of icons displayed on the display screen 142.

The worker carrying the information presentation device 140 (smartphone 1) shown in FIG. 21(a) is assigned tasks "1-α," "3-α," and "4-α." “1-α”, “3-α”, and “4-α” in FIG. 21(a) indicate icons corresponding to the respective tasks.

Since the assigned tasks are all in the section "α", the icons "1-α", "3-α", and "4-α" are displayed in a vertical line. However, the "2-α" task does not exist here, so the distance between the "1-α" and "3-α" icons is set larger than the size of one icon, for example. Arrangements are being made.

In other words, if there is a "2-α" task and this "2-α" task is assigned to the worker, the icons "1-α" to "4-α" will be displayed at regular intervals vertically. However, in this case, there is no work for "2-α" and there is no assignment of work for "2-α", so between the "1-α" and "3-α" icons, There is enough space available to place the "2-α" icon. By doing this, the worker can immediately recognize that there is no work assigned to "2-α".

In the example of FIG. 21(a), the coloring of the "1-α" icon is changed to green, which corresponds to "Completed", and the coloring of the "3-α" icon is changed to green, which corresponds to "Completed". ”) is changed to yellow, which is represented by the density of the gray scale. In the example of FIG. 21(a), the coloring of the "4-α" icon is in the initial state.

The notation "1/3" shown at the bottom of FIG. 21(a) indicates the relationship between the number of completed icons and the number of tasks to be performed, as described above. . In the example of Fig. 21(a), the total number of tasks to be performed is 3, and one task (here, "1-α") is "Completed", so the percentage of the number of completions is shown. "1/3" is displayed as the notation.

Next, the worker carrying the information presentation device 140 (smartphone 2) shown in FIG. 3-γ'' are assigned. When a plurality of sections (here, "β" and "γ") are assigned in this way, icons are arranged separately for each section on the display screen 142.

In the example of FIG. 21(b), the icons "1-β", "2-β", and "3-β" are arranged vertically, and on the right side, "1-γ" and "3-γ" ” icons are arranged vertically. Since there is no work assigned to "2-γ", there is enough space between the "1-γ" and "3-γ" icons to allow the "2-γ" icon to be placed.

With the "1-β", "2-β", and "3-β" icons displayed, the operator can swipe (slide) the display screen 142 to the left to move the displayed content to the left. The icons “1-γ” and “3-γ” placed on the right side appear on the display screen 142.

In the example of FIG. 21(b), the coloring of the icons "1-β", "2-β", and "1-γ" is changed to green, which corresponds to "Completed", and "3 -β" icon has been changed to red, which corresponds to the occurrence of a problem ("Problem"), as shown by the density of the gray scale. In the example of FIG. 21(b), the coloring of the "3-γ" icon is in its initial state.

In the example of FIG. 21(b), the total number of tasks is "5" and the number of completed tasks is "3", so the notation indicating the percentage of completed tasks is " 3/5" is displayed. Further, even when the icons of "1-γ" and "3-γ" are displayed, the display of "3/5" is maintained.

Next, the worker carrying the information presentation device 140 (smartphone 2) shown in FIG. Six tasks, ``1-ε'' and ``3-ε'', are assigned. Six icons are arranged vertically in each section of "α", "δ", and "ε".

In the example in Figure 21(b), the area between the icons “1-α” and “3-α”, the top of the icon “3-δ”, and the area between “1-ε” and “3-ε” There is enough space between the icons to place the missing icon.

With the "1-α", "3-α", and "4-α" icons displayed, the operator can swipe (slide) the display screen 142 to the left to move the displayed content to the left. The icon “3-δ” placed on the right side appears on the display screen 142. Furthermore, when the worker swipes (slides) the display screen 142 to the left while the "3-δ" icon is displayed, the displayed content scrolls to the left and the "1-δ" icon located on the right side is scrolled to the left. -ε” and “3-ε” icons appear on the display screen 142.

In the example of FIG. 21(c), the coloring of the icons "1-α", "3-δ", and "1-ε" is changed to green corresponding to "Completed", and "3 The fact that the coloring of the icons ``-α'' and ``3-ε'' has been changed to yellow corresponding to ``In progress'' is indicated by the density of the gray scale. In the example of FIG. 21(c), the coloring of the "4-α" icon is in the initial state.

In the example of FIG. 21(c), the total number of tasks is "6" and the number of completed tasks is "3", so the notation indicating the percentage of completed tasks is " 3/6" is displayed. Also, when the "3-δ" icon is displayed, "3/6" is maintained, and when the "1-ε" and "3-ε" icons are displayed, "3/6" is also displayed. display is maintained.

Further, the worker according to the example of FIG. 21(c) and the worker according to the example of FIG. -α” is assigned. For example, if the worker in the example of FIG. 21(c) sets the "1-α" icon to the "Completed" state (green), the information displayed in the example of FIG. 21(a) to which the same work is assigned is displayed. In the device 140 (smartphone 1), the "1-α" icon also changes to the "Completed" state (green).

In other words, the states of the corresponding icons are shared between the information presentation devices 140 of workers assigned the same task. The most recent operation is then reflected on the information presentation device 140 of multiple workers to whom the same work is assigned.

FIG. 22 shows a state in which the states of the icons in the information presentation device 140 shown in FIGS. 21(a) to 21(c) are reflected on the confirmation screen 250. On the confirmation screen 250 in the example of FIG. The check mark 302 corresponding to the work "3-α" and "3-ε" has been changed to yellow. Further, the check mark 302 corresponding to the work "3-β" is changed to red, and the check marks 302 corresponding to the work "4-α" and "3-γ" are in the initial state.

By displaying icons as exemplified in FIGS. 21(a) to 21(c) and displaying check marks 302 as exemplified in FIG. 22, the same effects as the examples shown in FIGS. In addition, it becomes easier for workers to understand the relationship between sections and items for the work assigned to them.

Additionally, if multiple workers are assigned the same task in the same section, information will be shared among the workers, allowing them to proceed with other tasks without wasting any time. can. As a result, it is possible to carry out mountain collapse (smoothing the work load) that suits the situation without any unreasonableness or waste.

Furthermore, when the information presentation device 140 is tilted so that the display screen 142 is horizontally elongated, a function (automatic rotation function) that automatically rotates the displayed content so that it fits the top and bottom of the display screen 142 is turned on. When used, it is possible to display more horizontally arranged icons at the same time.
