Description

In the information processing field, a network transmission network is essential as a system component. The present invention relates to a data collection management system that is a basis of a technique for utilizing a network transmission network.

There is no immediate information infrastructure (Web-based or network) for on-site data (operation data excluding equipment control data) required in the transition period that is not stable operation, such as on-site improvement activities and factory operation start-up is the current situation.
In such improvement activities and transitional periods, the following information infrastructure is required.
-Supports repeated trial and error-Supports analysis evaluation-Supports collection of data that seems to be temporarily needed-Temporarily monitors data on a detailed time axis-Decides a certain purpose and therefore In addition, it is impossible to support such a need for collecting data temporarily and to incorporate it into a system. This is because it is self-evident that a processing function cannot be built into a system because a required specification cannot be defined in advance.

  In general, an information processing system has a processing function built in on the premise of a routine work, and a system is built. The manufacturing site data handled there is encoded and encoded so that only a fixed processing apparatus incorporating a processing function can interpret. When support for non-standard work is required, the processing function for the non-standard work is defined by system modification, so that the standardization function is added and the solution is incorporated, but there is no immediacy.

  At the time of improvement activities and start-up of operations, an information infrastructure is needed that can obtain the desired site data in a timely manner when it is desired. However, since it cannot be defined as a routine work in advance, there is a problem that cannot be supported by conventional systems.

  The coding of on-site data is convenient for assumed routine work and is performed using general coding technology. As a result, the activities of the manufacturing site such as the meaning and character of the data inherent in the manufacturing site This is because the amount of information that expresses is lost. As described above, the coding based on the information processing loses the essence of the data and makes it impossible to handle the desired data by a processing device other than a fixed processing device when desired.

  The amount of information that expresses on-site activities such as the essential meaning and character of on-site data means that the words normally used in the company are handled as data in daily production activities. As a result of the loss of the amount of information by means of coding for converting the field work as an information system and converting it into a processing function, it is not possible to cope with a purpose that is not assumed in advance. Information processing lacks the essential understanding that it is a means and not a goal. It is necessary to change the way of thinking using the words used in production activities as production site data.

  On-site data generated in the field work is shared on the network with immediacy, and the necessary data can be freely selected and collected from the field data in order to obtain the data when the person wants it. , There is no network infrastructure to send to the required processing equipment.

  There is no network infrastructure that can select, collect, and transmit necessary data freely from the on-site data, and freely select management data stored in the information system for on-site data. There is no network infrastructure that can be collected and used in combination.

  The enterprise information system is a system in which a production site management system and a business management system are separated. As a company information system as a whole, the information held by both systems is stored in a storage device so that it can be stored as a whole, but the information from both systems must be combined immediately and used at the production site. It is difficult. Moreover, in the organization of a company, since the management departments of both systems are different and the concept of system construction is also different, information uniformity is lacking. As a result, despite having information, it cannot be effectively used for production activities and improvement activities at production sites, and management efficiency is reduced.

(b) The management data storage file is a file storing data used for business management,
(c) Each on-site data generator is
  For each occurrence of on-site data that models the words used in production activities,
A means for inputting data,
  A combination of unique information, which is essential information of each field data, and background information is built in.
When the event occurs, the above-mentioned specific information is taken in from the means for inputting on-site data.
A method for generating an event message by combining the embedded unique information and the built-in background information,
  Means for identifying data necessary for field activities from the management data stored in the management data storage file, and generating a static message having the same structure as the event message;
  Means for outputting these event messages and static messages to the network,
(d) The dictionary mission server
  A dictionary defining the name and attribute of the event message, a dictionary defining the name and attribute of the static message, and a collection condition menu for the event message and static message are networked to the data collection management device Means for transmitting via,
  In accordance with the collection conditions received from the data collection management device, the plurality of field data generation devices
Means for collecting and storing event messages and static messages that match the received collection conditions from among event messages and static messages sent to the network
  Means for transmitting the event message and the static message collected by the means for collecting the event message and the static message to the data collection management device;
(e) The data collection management device includes:
  Means for selecting event messages and static messages to be collected from the collection condition menu transmitted from the dictionary mission server, and transmitting these collection conditions to the dictionary mission server;
  Means for receiving event messages and static messages collected and accumulated by the dictionary mission server.

The on-site data is modeled on the words used in production activities.The words used on the site are production quantity, work completion, failure, quality defect, line stoppage, operation rate, work start, etc. It is a language that everyone involved in a company's production understands and is familiar with, and it deeply reflects the company's history, culture, and products it produces. This term is quantitative so that it can be treated as information, and the definition is rigorous and the ambiguity is eliminated and the model is made uniform so that it is referred to as field data.

  The on-site data is generated at the timing when a certain event occurs or a change occurs in the production activity. This timing is called an event. When an event occurs, the data essentially has information as to what event occurred, when, where and how, and what the event content is. This essential information is called unique information of field data. A collection of this unique information for each event is referred to as event data.

  Event data has the background of the occurrence of that data. Combine the event data with the background of what standards / standard work, which worker worked, which process was used, what kind of production plan was born. In this way, it is possible to make the information highly useful. An event message is obtained by adding this background information to event data and collecting it in one information message.

  In this way, when an event occurs, on-site data is combined with specific information to form event data, and then an information message with background information added to form an event message, which is highly useful information. It can be a unity.

Give a name to the event message, identify and organize the various event messages that occur in the field activity, and systematically organize it to create a dictionary (catalog) that represents the entire field activity. When creating a catalog, define the registrant, registration history, purpose of use, origin, management meaning, and necessary explanations as the attributes of the event message to complete the catalog. This catalog is housed in the dictionary mission server is connected to the network transmission network as a dictionary mission server capable of interpreting the event message.

  The event message is immediately sent to the network from a plurality of field data generating devices connected to the network transmission network and shared when the event occurs. In addition, it is temporarily stored for a certain period of time, assuming that it is used.

  The plurality of data collection management devices select event messages suitable for the purpose of collection using a catalog, determine collection conditions, collect and store them, and send them to another data collection management device. In this way, people who want event messages can use it whenever they want. A person who can handle a personal computer can use the data at any time according to the purpose to improve the site and start up the operation.

  On the other hand, management data is stored in an information system, and is searched and used according to business. From this management data, data necessary for field activities is identified, and the names and stored locations are organized to create a dictionary (catalog). This catalog can be integrated with the event message catalog.

  The management data registered in the catalog, organized as an information message having the same structure as the event message, and made available is called a static message. Static messages can be handled in the same way as event messages, and the data collection and management device selects static messages that meet the collection purpose using a catalog, collects and accumulates data according to collection conditions, and collects other data. Send to collection management device.

  The data collection management device collects static messages and event messages in the device, and then edits and reconfigures them to incorporate static message information into the background information in the event message, thereby providing a wide range of background information. Can be made more useful information.

  By creating an information infrastructure that can share on-site data with immediacy, it includes non-decision including decision making necessary for changing production activities that could not be handled by conventional systems, such as on-site improvement and start-up. Efficiently perform routine tasks, strengthen manufacturing capabilities, and respond quickly to changing external environments.

  The entire names of various site data are registered as a dictionary (catalog) including their attributes as event messages. The entire names of various site data are registered as a dictionary (catalog) including their attributes as event messages. Therefore, the desired data can be freely selected from the catalog. Since the collected and collected results can be obtained, it can be used dynamically for on-site improvement activities and on-site operations.

  After obtaining the desired data, it can be processed and edited using general-purpose software on a personal computer, and can be expressed as a table or graph, so that field operations staff can use it as it is.

A network transmission network is installed at the site, and multiple field data generators are connected to the network transmission network . As the field data generator, a personal computer is used, field data is fetched from the sequencer and the field terminal to the personal computer at the timing of generation, edited into an event message with background information built in the personal computer, and then sent to the network.

On the other hand, a dictionary mission server having a dictionary (catalog) and a collection condition (mission) is connected to the network, and then a plurality of data collection management devices are connected for users of field data.

The data collection management device selects the event / message name of the desired field data, determines collection conditions, and requests data collection to a dictionary mission server having a dictionary and collection conditions.

The dictionary mission server having the dictionary and the collection condition refers to the catalog and the collection condition, collects the requested data, and sends the collected and accumulated data to the request source. FIG. 1 shows a system configuration.
