Description

  The present invention relates to an information generation system that generates information units in stages.

  In factories, offices, and the like, various types of facilities are operating, and these facilities output field data indicating observation results of facilities, operations, or materials such as error information and status information. Site data is valuable data that contributes to factory and office operation management, product quality management, business management, and the like. However, the field data directly output from the equipment does not have a secondary or tertiary meaning other than a code or a mere observation numerical value, and a direct meaning such as an occurrence location and an occurrence date and time. Therefore, conventionally, data obtained at the site level is reinterpreted sequentially by each layer before reaching the management or management level, and information is added to the site data or the site data is interpreted to perform secondary, By changing the information into tertiary meaning, each level utilized field data.

  For this reason, a time lag tends to occur in how information is transmitted between the site level and the management or management level, and the site level and the management or management level tend to be separated.

  In addition, most of the processes at the production site, such as factory automation (FA) at the production site and process automation of equipment, are mechanized and automated. In such a production site, a monitoring and control system called SCADA, which measures and collects the status of each facility used in the production site by using sensors and measuring devices, is used. However, this monitoring and control system uses collected measurement data for controlling each facility, and does not sublimate the collected measurement data to a management or management level.

(Embodiment)
Hereinafter, an embodiment of an information generation system according to the present invention will be described in detail with reference to the drawings.

(Basic configuration)
As shown in FIG. 1, the information generation system according to the present embodiment generates information units indicating a united semantic content in a stepwise manner, bundles the generated information units together, and finally obtains higher-level information. A third information unit, which is a unit, is generated.

  The third information unit has a data structure in which a plurality of second information units are grouped together in the same data frame. For example, the third information unit is information in which information necessary and sufficient for improvement and analysis of the site, management, management, and the like of an organization is collected. is there. The second information unit has a data structure in which a plurality of first information units are grouped into the same data frame, and includes, for example, an event that has occurred at a site of an organization such as a production site and data supplementing the event. Is information indicating meaningful content. The first information unit is data that is a component of the second information unit.

  As described above, the information generating system 1 generates a second information unit by bundling a plurality of first information units, and further generates a third information unit by bundling a plurality of second information units. In addition, the group of semantic contents is extended from a local information unit to a wide-area information unit from the first information unit to the third information unit.

  The information generation system 1 is configured by a single computer or a group of distributed computers, and includes a storage unit 2, a data definition map 3, and a generation unit 4, as shown in FIG.

  The storage unit 2 is configured to include a storage or a memory, and has a first information unit storage unit 21 and a second information unit storage unit 22. The first information unit is stored in the first information unit storage unit 21 in advance. The second information unit storage unit 22 stores a second information unit obtained by grouping a plurality of first information units.

  Further, the storage means 2 stores a data definition map 3 and a program required for calculation in the generation unit 4.

  The data definition map 3 defines each information unit. The data definition map 3 has a second information unit map 32 and a third information unit map 33. As shown in FIG. 3, the second information unit map 32 is a table for associating the second information unit with a plurality of first information units constituting the second information unit. The second information unit map 32 associates, for example, the type of the second information unit with the type of the first information unit. As shown in FIG. 4, the third information unit map 33 is a table that associates the third information unit with a plurality of second information units that form the third information unit. The third information unit map 33 associates, for example, the type of the third information unit with the type of the second information unit.

  The generation unit 4 includes a CPU and generates each information unit. Specifically, the generation unit 4 includes a second information unit generation unit 42 and a third information unit generation unit 43.

  The second information unit generation unit 42 acquires a plurality of first information units from the first information unit storage unit 21 based on the second information unit map 32, and collects the plurality of first information units into a second information unit. Generate an information unit. Specifically, the second information unit generation unit 42 specifies a plurality of first information units associated with the second information unit to be generated from the second information unit map 32, and identifies the specified first information unit as the second information unit. It is acquired from one information unit storage unit 21. Then, one second information unit is generated by combining the acquired plurality of first information units into the same data frame. This second information unit has a variable length data structure. The second information unit generated in this way is stored in the second information unit storage unit 22.

  The third information unit generation unit 43 generates a third information unit by grouping a plurality of second information units based on the third information unit map 33. Specifically, the third information unit generation unit 43 specifies a plurality of third information units associated with the third information unit to be generated from the third information unit map 33, and identifies the specified third information unit as the third information unit. It is acquired from the two information unit storage unit 22. Then, one third information unit is generated by combining the plurality of acquired second information units into the same data frame. This third information unit has a variable length data structure.

  With such an information generation system 1, even if there is a change in the system due to a change in the business environment, the influence on the information unit at another stage can be reduced, and it is possible to easily respond to the change in the business environment. it can. For example, when it is desired to add an existing second information unit to the third information unit, it is only necessary to modify the third information unit map 33. That is, it is not necessary to change the second information unit map 32 only by making a correction for adding the association between the corresponding third information unit and the second information unit to be added. Further, the configuration of the third information unit may be the same, but when it is desired to change the first information unit constituting the second information unit in the third information unit, the modification of the association of the target second information unit must be changed to the second information unit. What is necessary is just to perform to the information unit map 32, and it is not necessary to change to the 3rd information unit map 33.

  As described above, the mechanism of configuring the information unit in a stepwise manner can minimize the influence of the system change, and can easily respond to changes in the business environment.

(Detailed configuration)
An example in which the information generation system 1 as described above is applied to a production site such as a factory that manufactures products will be described in detail. In the above description, the first information unit is stored in advance in the first information unit storage unit 21. However, here, the information generation system 1 performs the generation of the second information unit and the third information unit in advance. Data is collected via the network N, and the data is stored as a first information unit in the first information unit storage unit 21, or a first information unit is generated from the collected data and stored in the first information unit storage unit 21. Store.

  Specifically, the information generation system 1 is connected to a plurality of data generation devices 100 and data stock devices 200 via a network N, as shown in FIG.

  The information generation system 1, the data generation device 100, and the data stock device 200 are configured to include a computer, and include an arithmetic and control unit (CPU), a main storage device (RAM), an external storage device (HDD) storing an OS and an information generation application. Etc.), and a network adapter. The information generation system 1 is a single computer or a group of distributed computers. The information generation system 1 and the data stock device 200 are separate computers integrated or distributed over the network N.

  The information generation application is a program code or a control program that causes a computer to function as the information generation system 1, and is specifically an object code or a machine language instruction. The program code or control program may be written in a variety of source code programming languages, and then stored in a manner that is compiled or assembled into executable machine code or instructions appropriate for the arithmetic and control unit. This application is stored in a portable storage medium such as a CDROM, a DVDROM, or a USB memory, or a storage medium on a network N such as a server, and is installed in an external storage device. The computer constituting the information generating system 1 has a drive capable of reading a portable storage medium, and is connected to the network N so as to access a storage medium on the network N such as a server.

  The network N is a network N that conforms to a wired communication protocol such as IEEE802.3, a wireless communication protocol defined by IEEE802.11, and other protocols. The network N is a wired LAN network, a wireless LAN network, the Internet network, or a dedicated line. Etc., or a combination thereof.

(Generation of site data and storage of site data and supplementary data)
The data generator 100 is a device having a function of monitoring facilities such as FAs operating in a factory, and includes, for example, a PLC (programmable logic controller), a BCR (barcode reader), an RFID, a panel CON, a computer, and a mobile terminal. , Webcams, and various sensors. The data generator 100 generates site data.

  The site data is an observation result of a facility to be monitored by the data generation device 100, and includes observation data and status information indicating observation contents such as a temperature value and an operation state, and error information indicating an observation error. The site data is generated by the data generation device 100 detecting various events or performing regular observation.

  For example, site data is generated for each manufacturing process, for each event that occurred in the manufacturing process, and for each individual product that is the subject of the event. That is, the data generator 100 generates site data including a key code for specifying a manufacturing process, an event type, or an individual product in addition to the observation result.

  The site data has various formats depending on the data generator 100, such as image data, audio data, and character string data, and has various expressions such as a compression format depending on the data generator 100.

  The data stock device 200 includes a storage. For example, a memory 201 or a logger 202 provided in the data generator 100 and a database 203 connected to the network N are configured, and site data is stored in the memory 201 or the logger 202 according to the source of the site data. In the database 203, various supplementary data for supplementing the contents of the site data are stored in advance.

  Supplementary data is data necessary to analyze and evaluate the event of site data occurrence at each level of production, management, management, etc., and indicates directly or indirectly the cause of the site data occurrence. By providing a set with field data, it provides semantic content that cannot be derived from the content of field data alone.

  Examples of the supplementary data include background data indicating the background of the event of occurrence of the site data, and explanatory data indicating the quality of the site data or the site management data or a value standard. As background data, a characteristic factor diagram in which the relationship between characteristics and factors are systematically connected by lines (in a tree form), a failure tree that graphs the relationship between the causes of equipment and equipment failures, workers and equipment Or, a man-machine chart that charts the associated work with the equipment based on the work sequence, work contents, work time, etc., know-how of veterans, supervisors and technicians on site, past measurement data (site data) And the like. The description data includes quality standard values, caution upper limit values, caution lower limit values, danger upper limit values, danger lower limit values, design drawing tolerances, standard working hours, machine operation reference values, and actions (text data) for event occurrences. Is mentioned.

  Site management data is data converted and used and managed at a production site by one or a plurality of site data. For example, if the product manufactured at the production site is a cup, and the site data is the diameter of the measured cup, the site management data is the average diameter, the maximum diameter, and the minimum diameter of the cup. In this case, the supplementary data is, for example, a range of the diameter of a good cup or a range from the minimum diameter to the maximum diameter.If the average diameter of the measured cup is within the range from the minimum diameter to the maximum diameter of the supplementary data, the cup is provided. Can be determined to be non-defective, and if the measured minimum or maximum diameter of the cup is out of the range from the minimum to maximum diameter of the supplementary data, the manufactured cup can be determined to be defective. Further, assuming that the site data is a temperature expressed in Fahrenheit and the site uses and manages the temperature in Celsius, the temperature converted from Fahrenheit to Celsius is the site management data. In this case, the supplementary data includes, for example, a safe temperature range described in Celsius, a dangerous temperature upper limit value, and a dangerous temperature lower limit value described in Celsius.

  Further, the supplementary data includes a key code that specifies a manufacturing process, an event that occurred in the manufacturing process, or a product individual manufactured in the manufacturing process.

(Transfer of data)
As shown in FIG. 6, the information generation system 1 includes a data transfer unit 5, which collects site data and supplementary data from the data stock device 200, and collects the collected site data and supplementary data. The data is transferred to the storage unit 2 according to the definition map 3 and stored. Specifically, the storage unit 2 has a management area 20. The data definition map 3 has a data tag map 30.

  FIG. 7 is a diagram showing the transfer of site data and supplementary data to the management area 20. The management area 20 is a memory area configured with a memory and secured in advance for each site data and for each attribute value indicating the type of supplementary data. The attribute value indicating the type of the supplementary data is defined on the data stock device 200, for example. As shown in FIG. 7, the management area 20 is provided with a tag for identifying the memory area for each divided memory area. With this tag, site data and supplementary data are identified. That is, since the management area 20 is secured for each site data and for each attribute value indicating the type of supplementary data, the information generation system 1 can use the tags to store the site data and the supplementary data without knowing the contents of the data in the management area 20. Can be managed. Also, this tag has a ranking.

  As shown in FIG. 8, the data tag map 30 is a table that associates site data and supplementary data stored in the data stock device 200 with tags attached to the management area 20 where the site data and supplementary data are stored. It is. Further, the storage locations of the site data and the supplementary data and the data stock device 200 of the site data and the supplementary data correspond to 1: 1 while the management area 20 and the tag correspond to 1: 1. . Therefore, the data tag map 30 that associates the site data and the supplementary data with the tag associates the storage location of the site data and the supplementary data stored in the data stock device 200 with the management area 20. In particular, regarding the site data, the data tag map 30 associates the data generation device 100 that is the source of the site data with the management area 20 that is the storage destination of the site data by using a tag.

  The data transfer unit 5 includes a CPU, and collects site data and supplementary data specified by the tag from the data stock device 200 based on the data tag map 30, and attaches a tag corresponding to the site data or the supplementary data. The collected field data or supplementary data is stored in the management area 20 that has been collected. That is, the data transfer unit 5 transfers the site data and the supplementary data stored in the data stock device 200 to the corresponding management area 20.

  The transfer of the data transfer unit 5 is performed periodically or periodically by polling. That is, the data transfer unit 5 refers to the data tag map 30 and sequentially collects the site data or the supplementary data from the data stock device 200 according to the order of the tags defined in the data tag map 30, and collects the site data or the supplementary data. The data is transferred to the corresponding management area 20. For example, assuming that the tags are ranked in the order of a1 to a39, the site data or supplementary data is transferred to each management area 20 in the order of a1, a2,..., A39, and returns to a1 again. Since the patrol is performed in this manner, changed site data can be collected and stored in the management area 20. This transfer may be executed even if there is no change in the site data and the supplementary data stored in the data stock device 200.

(First information unit)
The data definition map 3 has a first information unit map 31. The first information unit map 31 defines a first information unit. As illustrated in FIG. 9, the first information unit map 31 is a table that associates the first information unit with a tag attached to the management area 20. Specifically, the first information unit map 31 associates the type of the first information unit with a tag.

  The first information unit map 31 associates one or more tags with one first information unit. That is, the first information unit is site data, supplementary data, or site management data, and is information of granularity used and managed at the site.

  That is, if one site data or one supplementary data is data used and managed at the site, the site data or the supplementary data becomes the first information unit as it is. On the other hand, if one or a plurality of site data is not data used and managed at the site, the first information unit map 31 defines an arithmetic process for the one or a plurality of site data, and uses and manages the data at the site. Is converted to data of the given granularity. This data is site management data. The arithmetic processing is arithmetic processing such as four arithmetic operations such as conversion of units and calculation of an average value, a maximum value, or a minimum value of a plurality of site data.

  Further, the first information unit map 31 associates a tag attached to the management area 20 with a storage location of the first information unit storage unit 21 where the first information unit is stored for each first information unit.

  Further, a tag attached to the management area 20 to be monitored (hereinafter, also referred to as a monitored memory area) is called a change tag, and a tag attached to the management area 20 related to the monitored memory area is called an accompanying tag. , The first information unit map 31 stores the first information unit storage unit 21 for the site data or supplementary data stored in each management area 20 to which the change tag and a plurality of accompanying tags related to the change tag are attached. Is associated with the processing location of the site data or the supplementary data. That is, the first information unit map 31 stores the tag management area 20 from which data is collected, the collection timing, the range related to the collected data, the processing method of the collected data, and where the data is stored. Is defined. The site data and the supplementary data included in the management area 20 to which the change tag and the plurality of accompanying tags related to the change tag are attached can be the first information unit constituting the second information unit. The processing of each site data and supplementary data associated with each other in the first information unit map 31 is performed, for example, by transferring to the storage location of the first information unit storage unit 21 defined by the first information unit map 31, An arithmetic process such as an arithmetic operation such as calculation of an average value, a maximum value, or a minimum value of site data is exemplified.

  As shown in FIG. 6, the information generation system 1 includes a data transfer unit 6 and a data conversion unit 41. The data transfer unit 6 includes a CPU and, as shown in FIG. 10, according to a first information unit map 31, corresponds to a single tag, and has one field data and one supplementary data as a first information unit. Is transferred to the first information unit storage unit 21. Specifically, the data transfer unit 6 specifies a tag corresponding to the target first information unit, acquires field data or supplementary data from the management area 20 to which the specified tag is attached, and stores the first information unit. The data is transferred to a prescribed storage location of the unit 21.

  The data conversion unit 41 is configured to include a CPU, specifies a tag corresponding to the target first information unit according to the first information unit map 31, and stores one or a plurality of sites from the management area 20 to which the specified tag is attached. Get the data. Then, the acquired data is converted into site management data used and managed at the site, and the site management data is set as a first information unit and stored in a storage location of the corresponding first information unit storage unit 21. When generating the site management data, the data conversion unit 41 includes the key code included in the site data constituting the site management data in the site management data.

  In the present embodiment, as shown in FIG. 11, the data transfer unit 6 includes a change monitoring unit 61a and a data acquisition unit 61b. The change monitoring unit 61a includes a CPU, and monitors a change in data stored in a monitoring target memory area to which a change tag defined in the first information unit map 31 is attached. The term "data" as used herein refers to field data or supplementary data, and "change" refers to storing data in a memory area where data has not yet been stored, rewriting stored data, or erasing stored data. Say. Upon detecting a change in data, the change monitoring unit 61a notifies the data acquisition unit 61b.

  The data acquisition unit 61b includes a CPU and, at the timing when the data in the monitored memory area changes, according to the first information unit map 31, associates the data in the monitored memory area with the change tag with the associated data. And the data in the management area 20 to which the accompanying tag is attached. Then, the data transfer unit 6 generates a folder, stores the plurality of acquired site data and supplementary data in the folder, and stores the folder in a prescribed storage location of the first information unit storage unit 21. Thereby, the related data is updated in the first information unit storage unit 21. The data transfer unit 6 does not combine the acquired site data and supplementary data into one data structure, and the site data and supplementary data in the same folder are independent. Alternatively, the data transfer unit 6 does not put the acquired site data and supplementary data in the same folder, and stores each site data and supplementary data in the storage location of the first information unit storage unit 21 defined by the first information unit map 31. Store each. Even in this case, the related data is updated in the first information unit storage unit 21.

(Generation of the second information unit)
As shown in FIG. 12, the second information unit map 32 of the present embodiment defines a second information unit for each production management unit. The production management unit is a minimum unit for dividing a production site or a production plan. Since a production site or a production plan is often divided into process units constituting a product manufacturing process for production management, when one product is manufactured through a plurality of processes, the production management unit is: For example, a process. When one product is manufactured through a plurality of processes, and each process includes a plurality of operations such as processing, storage, assembly, and inspection, the production management unit is an operation. Further, the production management unit may be an apparatus used in the process.

  The second information unit is composed of a plurality of first information units, and is specifically composed of site data or site management data, and supplementary data. The types of the second information units are classified into six types: production results, productivity results, quality results, trouble information, equipment abnormality information, and unique information of products manufactured in the production management unit.

  The production record, productivity record, and quality record are periodically generated. That is, it is generated each time the production of a product is completed in the production management unit. The production result is information on the production amount of the product, for example, on-site data on the quantity such as the number of products produced in the production management unit, and supplementary information such as the number of products planned to be produced in the production management unit. It contains data and is composed. The productivity record is information on the production time of the product, and includes, for example, site data on the production time of the product in the production management unit and supplementary data such as the standard production time of the product. . The quality record is information related to the quality of the product, and includes, for example, site data such as quality measurement data of the product manufactured in the production management unit and supplementary data such as manufacturing conditions and quality standards.

  The trouble information and the equipment abnormality information are generated irregularly for each production management unit. That is, it is generated every time a trouble or equipment abnormality occurs, and is not generated when there is no trouble or equipment abnormality. The trouble information is information relating to an abnormality that occurred during the manufacturing process, although there is no abnormality in the equipment used in the production management unit. For example, it includes on-site data such as measured values such as material temperature and pressure measured during the manufacturing process and conveyor stop time, and supplementary data such as standard values for measured values and manufacturing conditions. The equipment abnormality information is information relating to the equipment abnormality, for example, on-site data such as the equipment in which the abnormality has occurred, the name of the abnormality, the equipment stop time, the abnormality rank indicating the urgency of the response, the periodic maintenance result, and the time of the occurrence of the abnormality. And supplementary data such as emergency treatment methods.

  The unique information is information unique to each production management unit that cannot be classified into the above-mentioned production results, productivity results, quality results, trouble information, and equipment abnormality information. For example, as the unique information, in-process inspection information indicating the inspection result of a product in the course of manufacturing, verification information as a result of verifying whether parts or members of the product are correct with a barcode, etc., and production of the product. The information includes equipment status information generated even if the power is not used, utility consumption information that is information on energy required for manufacturing, and the like.

  As illustrated in FIG. 13, the second information unit generation unit 42 of the present embodiment generates a second information unit for each production management unit according to the second information unit map 32. For example, when the production management unit is a process, the second information unit generation unit 42 generates a second information unit of a production result, a productivity result, and a quality result for each process, and outputs trouble information and equipment according to the occurrence status. A second information unit of the abnormality information is generated. In addition, the second information unit generation unit 42 stores the generated second information unit in the storage location of the second information unit storage unit 22 associated with the second information unit map 32.

(Generation of the third information unit)
As shown in FIG. 14, the third information unit map 33 of the present embodiment defines a third information unit by a key code. That is, in order to associate the third information unit with the plurality of second information units forming the third information unit, the plurality of second information units forming the third information unit are included in the second information unit. The link is made by a key code (that is, a key code included in site data, site management data, and supplementary data constituting the second information unit).

  For example, if a manufacturing process for manufacturing a certain product is divided into processes A to C, and a second information unit generated in each of the processes A to C includes a common key code, each process is performed by a common key code. The relationship between the second information units generated in A to C is linked, and one third information unit is defined.

  The third information unit may be defined by one common key code as described above, or may be defined by a plurality of different key codes.

  For example, as shown in FIG. 15, a manufacturing process for manufacturing a certain product includes a product completing process of assembling two sets of the product and manufacturing the product, and assembling the two parts to form the set. Let us consider a case that includes a group manufacturing process of manufacturing and a component manufacturing process of manufacturing the component from the material. In this case, the second information unit generated in each process includes a product code S1 for identifying the product, a group code S2a and S2b for identifying each group, and component codes S3a to S3d for identifying each part. It is assumed that material codes S4a to S4d for identifying each material are included. As shown in FIG. 16, two group codes S2a and S2b are derived from the product code S1, part codes S3a and S3b are derived from the group code S2a, and part codes S3c and S3d are derived from the group code S2b. The material codes S4a to S4d are derived from the component codes S3a to D3d, and the link that associates the second information unit in the third information unit map 33 has a tree structure. In other words, the third information unit map 33 defines the third information unit using the product code S1, the group codes S2a and S2b, the component codes S3a to S3d, and the material codes S4a to S4d as key codes.

  Other key codes include a lot number for identifying a production lot, a bogie number for identifying a bogie used at a production site, an instruction number for identifying an instruction book, a device number for identifying a device used at a production site, and the like. Is mentioned.

  As illustrated in FIG. 17, the third information unit generation unit 43 acquires a plurality of second information units having a common key code from the second information unit storage unit 22 according to the third information unit map 33, and acquires the acquired second information unit. The third information unit is generated by linking the two information units and combining them together in the same data frame.

  For example, the third information unit generation unit 43 obtains the second information unit having the common key code generated in the above-described steps A to C from the second information unit storage unit 22 and generates the third information unit. The third information unit is information relating to an event that has occurred in a manufacturing process of manufacturing one product, and is a history of the manufacturing process of the product. For example, when six types of second information units of production results, productivity results, quality results, trouble information, equipment abnormality information, and unique information occur in each of the processes A to C, the third information unit generation unit 43 A third information unit is generated by acquiring and linking at least one or more types of second information units from the process. For example, by acquiring and linking the second information unit of the production result from each of the processes A to C, the third information unit becomes the second information unit of the production result of the product and the second information unit of the production result of the group. , And a second information unit of part production results.

  Further, when the manufacturing process for manufacturing a certain product includes the above-described product completing process, group manufacturing process, and component manufacturing process, if each process is a production management unit, the third information unit generation unit 43 In order to generate a third information unit relating to the product, a second information unit having a product code S1 is obtained, and a second information unit including a group code S2a or S2b included in the second information unit is obtained. Further, a second information unit including the component code S3a, S3b, S3c or S3d included in the second information unit including the group code S2a or S2b is obtained, and the material codes S4a, S4b, A second information unit including S4c or S4d is obtained. A third information unit is generated by linking these acquired second information units and putting them together. The third information unit is a history of the product from the start of the manufacture of the product to the completion of the manufacture, such as a part manufacturing process, a group manufacturing process, and a product completion process.

(Action)
A specific example of generation of the third information unit by the information generation system 1 of the present embodiment will be described.

  The product A is composed of parts B1 and B2, the part B1 is composed of a material C1, and the part B2 is composed of a material C2. That is, as shown in FIG. 24, the manufacturing process of the product A includes a first component manufacturing process of manufacturing the component B1 from the material C1, a second component manufacturing process of manufacturing the component B2 from the material C2, and the components B1 and B2. And a component assembling process of manufacturing the product A.

  Site data is generated upon completion of the work in each process, the site data and supplementary data are collected in the management area 20 by the data transfer unit 5 and the data tag map 30, and the data transfer unit 6, the data conversion unit 41, and the first information unit map The first information unit is stored in the first information unit storage unit 21 according to 31, and the second information unit is generated according to the second information unit generation unit 42 and the second information unit map 32.

  In the first component manufacturing process, a production record, a productivity record, and a quality record of the part B1 are generated. That is, the production result of the component B1 is a second information unit including the production amount of the component B1 and the planned production amount. The productivity record of the part B1 is a second information unit including the manufacturing time of the part B1 and its standard manufacturing time. The quality record of the component B1 is a second information unit including measurement data such as the size and weight of the component B1, an image, and the like, manufacturing conditions, quality standard values, and the like. Each second information unit includes a code related to the manufacture of the component B1. Since the component B1 is manufactured from the material C1, for example, a material code c1 indicating the material C1 and a component code b1 indicating the component B1 are given.

  In the second component manufacturing process, a production record, a productivity record, and a quality record of the part B2 are generated. That is, the production result of the component B2 is a second information unit including the production amount of the component B2 and the planned production amount thereof. The productivity record of the component B2 is a second information unit including the manufacturing time of the component B2 and its standard manufacturing time. The quality record of the part B2 is a second information unit including measurement data such as the size and weight of the part B2, an image, and the like, manufacturing conditions, quality standard values, and the like. Each second information unit includes a code related to the manufacture of the part B2. Since the component B2 is manufactured from the material C2, for example, a material code c2 indicating the material C2 and a component code b2 indicating the component B2 are given.

  In the component assembling process, a production record, a productivity record, and a quality record of the product A are generated. That is, the production result of the product A is a second information unit including the production amount of the product A and the planned production amount. The productivity record of the product A is a second information unit including the production time of the product A and its standard production time. The quality record of the product A is a second information unit including measurement data such as the size and weight of the product A, an image, and the like, manufacturing conditions, quality standard values, and the like. Each second information unit includes a code related to the manufacture of the product A. Since the product A is manufactured from the component B1 and the component B2, for example, a component code b1 and a component code b2 are given.

  In each step, a second information unit of trouble information and equipment abnormality information is generated due to occurrence of a trouble or equipment abnormality. The second information unit is generated irregularly and includes a code of a subject (material C1, material C2, part B1, part B2 or product A) involved in each step.

  The third information unit requires different components for each functional organization at the production site. Therefore, a third information unit is defined for each functional organization, and the third information unit map 33 is set according to the purpose of the functional organization. For example, as shown in FIG. 25, assuming that a production site is divided into a production planning section, a process improvement section, a quality assurance section, a maintenance / construction section, a production technology section, and a manufacturing section as functional organizations, The current production line production results are needed to improve the production plan.

  Therefore, the third information unit map 33 shows the production results of the component B1 including the component code b1, the production results of the component B2 including the component code b2, and the production results of the product A including the product code a1, by the respective codes b1, Links are made by b2 and a1. The third information unit generated according to the third information unit map 33 includes the production results of each process. Since each production result includes the actual production amount and the planned production amount, the user of the production planner can grasp the production amount and evaluate whether the production has been completed as planned. That is, the production amount can be locally grasped as in each process, and the production amount can be grasped in a wide area over the entire production process of the product A.

  The process improvement section needs productivity results, quality results, and trouble information in order to grasp the status of each process at the current production site.

  Therefore, the third information unit map 33 includes the productivity record and the quality record of the part B1 including the part code b1, the productivity record and the quality record of the part B2 including the part code b2, and the productivity of the product A including the product code a1. The results and the quality results are linked by the codes b1, b2, and a1. The third information unit generated according to the third information unit map 33 includes the productivity record and the quality record of each process. Since each productivity record includes the manufacturing time of each process and its standard manufacturing time, the user of the process improvement staff can evaluate the productivity. Further, since each quality record includes measurement data of each process and its quality standard, the quality of the parts B1, B2 and the product A can be evaluated.

  If the manufacturing time of any process exceeds the standard manufacturing time, or if the quality is not maintained in any process, it is considered that some trouble occurred during the process. Awareness is born. When trouble information is not defined in the third information unit, the third information unit map 33 is corrected. That is, trouble information including at least one of the product code a1, the part codes b1, b2, and the material codes c1, c2 is defined as a component of the third information unit. Thus, from the trouble information included in the third information unit, it is possible to identify a factor requiring a longer manufacturing time or a factor of quality deterioration than necessary, and improve productivity and quality.

  As described above, the data tag map 30, the first information unit map 31, and the third information unit map 33 are simply modified so that the existing second information unit generated in each step is included in the third information unit. It is possible to cope with a system change without affecting the second information unit map 32.

  The quality assurance clerk needs quality records in order to grasp the quality of products manufactured at the production site.

  Therefore, the third information unit map 33 indicates the quality results of the component B1 including the component code b1, the quality results of the component B2 including the component code b2, and the quality results of the product A including the product code a1, by the respective codes b1, b2, Linked by a1. The third information unit generated according to the third information unit map 33 includes the quality record of each process. Since each quality record includes the measurement data of each process and its quality standard, the quality of the parts B1, B2 and the product A can be evaluated. That is, the quality of the entire manufacturing process of the product A can be grasped.

  The maintenance and construction staff needs equipment abnormality information for maintenance of equipment and devices used at the production site.

  Therefore, the third information unit map 33 includes the equipment code c1, the equipment abnormality information including the part code b1, the material code c2, the equipment abnormality information including the part code b2, the equipment code b1, b2, and the equipment abnormality information including the product code a1. Are linked by the respective codes c1, c2, b1, b2, a1. The third information unit generated according to the third information unit map 33 includes equipment abnormality information generated in each process. Equipment error information for each process includes information on the error, such as the equipment in which the error occurred, the name of the error, and the time at which the equipment was stopped, as well as the error rank indicating the urgency of the response, the regular maintenance results, and the maintenance of emergency treatment methods when an error occurs. Since the information is included, it is possible to appropriately cope with the equipment abnormality.

  Production engineers need productivity records and trouble information in order to build efficient production sites.

  Therefore, the third information unit map 33 includes the productivity results of the component B1 including the component code b1, the productivity results of the component B2 including the component code b2, the productivity results of the product A including the product code a1, the material code c1, Trouble information including c2, component codes b1, b2, or product code a1 is linked by each code c1, c2, b1, b2, a1. The third information unit generated according to the third information unit map 33 includes the productivity record of each process. Since each productivity record includes the actual production time and the production standard time, It is possible to evaluate whether or not the production has been completed as planned while grasping the production time. Further, from the trouble information, it is possible to grasp the problem of productivity improvement over the entire manufacturing process, which can lead to improvement.

  The manufacturing staff needs production results, productivity results, quality results, trouble information, and equipment abnormality information in order to grasp every situation at the production site. In addition, each clerk may need unique information.

  As described above, the third information unit is defined for each functional organization, and the third information unit map 33 may be set according to the purpose of the functional organization, and an existing second information unit may be added as necessary. By modifying the third information unit map 33, a necessary third information unit can be obtained without affecting other maps and other information units.

  In addition, when adding, modifying, or deleting an existing first information unit from the second information unit, only the modification of the second information unit map 32 is required, so that there is no need to affect other maps and other information units. A second information unit can be obtained. The first information unit to be added, modified, or deleted is, for example, supplementary data.

  As described above, since the data definition map 3 is composed of the maps of the respective layers, it is possible to easily deal with environmental changes. For example, since the business environment needs to be improved even in a rapidly changing environment, necessary information is likely to change in accordance with changes in the environment. Such a case can be dealt with by modifying the map using the existing information unit.

  In addition, since the third information unit is generated along the flow of goods, it is easily converted into a story, a chain of awareness, discovery, interpretation, and prediction and prediction, and it is easy to understand the phenomena at the production site, thereby making improvements. Can be made easier to find.

(effect)
(1) The information generation system 1 of the present embodiment includes a first information unit storage unit 21 in which a plurality of first information units as information units are stored, a second information unit including a plurality of first information units, A second information unit map 32 for associating a plurality of first information units constituting the second information unit, and a plurality of first information units from the first information unit storage unit 21 based on the second information unit map 32. The second information unit generation unit 42 that acquires and collects the plurality of first information units to generate a second information unit, a third information unit including a plurality of second information units, and a third information unit. A third information unit map 33 for associating a plurality of second information units with each other, and a third information unit for generating a third information unit by grouping the plurality of second information units based on the third information unit map 33 And a generation unit 43.

  As a result, since the information units are collectively generated in stages from the first information unit to the third information unit, it is possible to easily cope with a change in the business environment, and as a result, the first information unit is It is possible to immediately understand the secondary and tertiary meanings of the information. According to the present embodiment, even if the system is changed due to a change in the business environment, the influence on the information unit at another stage can be reduced. For example, when one second information unit constituting the third information unit is to be changed to another existing second information unit, in the third information unit map 33, the second information unit before the change is replaced with the second information unit after the change. It is sufficient to make corrections in two information units, and there is no need to correct the other second information unit maps 32. As described above, since the information generation system 1 has an autonomous structure based on local information in each stage of the information unit, it is possible to perform a parallel design work for each stage and a parallel test after the design. The time for designing can be greatly reduced.

(2) The first information unit is site data generated at the production site, supplementary data that supplements the contents of the site data, or site management data generated from a plurality of site data and used and managed at the production site. The site data is data generated from the data generator 100 provided at the production site, and the supplementary data is background data indicating the background of the generation of the site data, and whether the content of the site data or the site management data is good or bad. Or, the second information unit map 32 may include description data indicating a value standard, and the second information unit map 32 may define a second information unit including site data or site management data and supplementary data for each production management unit that divides a production site. did.

  This makes it possible to grasp the secondary and tertiary meanings of the site data or the site management data for each production management unit. That is, since the second information unit includes the background data and the description data in addition to the site data or the site management data, a user who directly or indirectly participates in the production management unit becomes independent in the production management unit. Thus, it is possible to understand the background of the generation of the site data and the quality or value of the site management data. In particular, since the site management data itself is data used and managed at the production site, it is easy for a user at the production site to understand, and the site management data itself can be evaluated based on background data and explanation data. Awareness and knowledge of data generation can be obtained.

(3) A management area 20 which is a memory area to which an identifiable tag is attached and stores site data generated at the production site or supplementary data for supplementing the contents of the site data, a first information unit and a tag. First information unit map 31 to be associated, and data transfer for transferring field data or supplementary data as a first information unit to the first information unit storage unit 21 from a management area to which a tag specified by the first information unit map 31 is attached. And a unit 6.

  As a result, the site data or supplementary data necessary to construct the first information unit is identified by the tag, and the information generation system 1 obtains the first information unit while the content or data format of the site data or supplementary data is obtained. You do not depend on. That is, based on the first information unit map 31, the data transfer unit 6 specifies the tag of the management area 20 storing the site data or the supplementary data as the first information unit, and specifies the management area specified by the tag. Since the site data or the supplementary data is obtained from 20 and used as the first information unit, even if the content or the data format of the site data or the supplementary data is changed, the tag is specified and the tag is used. There is no change in acquiring field data or supplementary data from the specified management area 20 and using the data as the first information unit. Therefore, the first information unit can be obtained by uniformly handling various kinds of site data and supplementary data.

(4) The information generation system 1 is connected to a data generation device 100 that generates site data via a network N, and a data generation device 100 that is a source of the site data and a management area 20 that is a storage destination of the site data. And a data transfer unit 5 that collects site data based on the data tag map 30 and stores the collected site data in the management area 20 to which the corresponding tag is attached. I prepared for it.

  Thereby, even if the information generation system 1 does not know the substance of the site data, the site data can be automatically stored in the management area 20 corresponding to the source. In other words, in the conventional information generation system 1, discriminators of the type, format, and structure style are added to the data side, and if the data is not defined in advance so that the data can be handled, the data Was difficult to handle. That is, data unknown to a system that is not defined in advance could not be handled. On the other hand, in the present embodiment, the source of the site data is associated with the management area 20 in which the site data is stored, so that the site data of the predetermined source is stored in the management area 20 as the predetermined storage destination. The data can be stored, and the site data can be handled in a unified manner without concern for the actual site data.

(5) The production management unit is a step constituting a product manufacturing process, and the third information unit map 33 defines the third information unit by a plurality of second information units generated in the manufacturing process. did. As a result, it is possible to understand the background of the event that occurred in the manufacturing process of the product and to evaluate the event along the manufacturing process.
