ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an FA (Factory Automation) information managing method in which a plurality of processes for manufacturing a product is summed, in which raw data in the respective processes is collected, in which predetermined information processing which is predictable in advance, such as statistics, comparison, evaluation, and the like, is carried out, and in which the respective processes are managed on the basis of the information processing.
2. Description of the Related Art
A distributed FA information management system in the manufacturing industry is based on a client/server model. In such FA information management system, in order to access to the information owned by the system, it is necessary to access to a server (storage device) which stores the information.
The information stored in the server is subjected to predetermined information processing which is predictable in advance, such as statistics, comparison, evaluation, and the like (e.g., actual production, actual operation, and the like). An operator can fetch necessary data from the data which has been subjected to predetermined information processing.
Such FA information management system is suitable for routine information processing (permanent routine information, such as an immediate report, a daily report, a monthly report, and the like) or data processing which is frequently reused.
However, the system is not suitable for data processing which is irregular and unpredictable in advance (e.g., collecting operation information or quality/QA information for recognizing the current state which is necessary for frequent amelioration and improvement in the manufacturing industry; or collecting evaluated data after manufacturing method or facility is improved). Further, from the aspect of cost, it is often difficult to mount data processing function which is used only for a short period and is less frequently reused (e.g., in a case in which an operator wants to know data only during the trial operation; or in a case in which he/she wants to investigate data immediately after the manufacturing process has been changed).
Namely, data which is necessary for improving the above-described production control is different in accordance with a process to be improved and ameliorated. In a case in which end data (e.g., dimension value and the like which is measured when raw materials are conveyed) which does not remain in the server as data is needed, a specific operator must be placed at the predetermined process for collecting the data. Moreover, it is unpredictable when and where trouble occurs. It is nearly impossible in reality to store the data as raw information (unprocessed information).
In this way, due to the variety of requests of data, the difficulty of prediction, the complication of structure of a database or a file, and the opacity of processing history, data which is less frequently reused cannot be managed by the server.
SUMMARY OF THE INVENTION
With the aforementioned in view, an object of the present invention is to obtain an FA information managing method in which drawbacks of a conventional client/server model are solved, in which information in accordance with the request of an operator can be easily fetched by him/her in a plurality of processes for manufacturing a product, and in which predetermined information processing, such as statistics, comparison, evaluation, and the like, which is necessary for production control, such as improvement, amelioration, and the like, can be carried out rapidly.
A first invention is an FA information managing method, comprising the steps of: transmitting raw information in a plurality of processes for manufacturing a product or a message group into which the raw information is appropriately classified to a data transmission network on a network, and designating and fetching the raw information or the message group; and on the basis of the fetched raw information or message group, executing new information processing which is unpredictable in advance.
In accordance with the first invention, the raw information, (cf. the processed information is subjected to data processing and is thereby obtained) which is not processed and has minute manufacturing processes, or the message group, into which the raw information is appropriately classified, flows into the data transmission network on the network. As the raw information or the message group is designated and fetched, the new processing information which is unpredictable in advance can be executed.
The raw information or the message group transmitted to the data transmission network can be fetched by using a technology in which the processed information (the message group) flows into the data transmission network and necessary information is fetched at random from the message group.
In the first invention, new information processing which is unpredictable in advance is executed on the basis of the fetched raw information and message group. Namely, fetching of the raw information or the message group for obtaining statistics, comparison, evaluation, and the like, which is currently needed and programming of executing a processing based on the raw information and the like can be performed without having adverse effect on the other device connected to the network.
Thus, in the system based on the conventional client/server model, it is extremely difficult to cope with rapidly and easily various types of requests in the future. On the contrary, the first invention is based on a mechanism in which, at the time of propagation of antibody cells, random gene recombination is effected so as to cope with various types of extraneous antigens and is not based on a mechanism in which, like a biological immune model, antibody manufacturing information based on the past experience is succeeded and prepared genetically in advance against various types of extraneous antigens.
Namely, in the first invention, in order to cope with various types of requests for processing data which is predicted in the future, data which has been processed beforehand is not prepared, and a broadcast-typed (or a node address independent type having an address server) message group which directly flows on the network is observed. When it is necessary to process the message group or the raw information included in the message group, a storage device or a storing method which is suitable for the amount of data or processing is prepared. The raw information or the message group on the network is directly accessed and data is collected and processed independently from the existing storage device.
Since the first invention has such mechanism, it is unnecessary to have knowledge on the structure of a file or a database in the existing storage device, the method of accessing, the processing history, and the like. Also, various types of requests for processing data which is needed at the time of amelioration and improvement in the manufacturing process can be coped with flexibly and rapidly.
As described above, in the first invention, the information in accordance with the operator's request can be easily fetched in the plurality of processes for manufacturing a product, and predetermined information processing, such as statistics, comparison, evaluation, and the like, which is necessary for production control of improvement, amelioration, and the like, can be carried out rapidly.
A second invention is an FA information managing method in which a plurality of processes for manufacturing a product is summed, in which raw data in the respective processes is collected, in which predetermined information processing which is predictable in advance, such as statistics, comparison, evaluation, and the like, is carried out, and in which the respective processes are managed on the basis of the information processing, comprising the steps of: fetching the raw information transmitted to a data transmission network on a network while designating collection timing and period as occasion demands; a
