摘要:
Die Erfindung bezieht sich auf einen Echtzeit-Prozesshistorien-Server (13) für den Einsatz in einem Prozessleitsystem mit einem Prozessinformationsmanagement-System (PIMS) und einem oder vorzugsweise mehreren verteilten Verarbeitungssystemen (Distributed Control Systems DCS, 14.1 bis 14.n). Der Echtzeit-Prozesshistorien-Server (13) weist einen kombinierten PIMS/DCS-Server (12) und einen Report-Server (11) auf, und ist dafür eingerichtet , mittels des Report-Servers (11) sowohl Clients (1, 5), als auch gleichzeitig Operator-Arbeitsplätzen (2) der DCS-Systeme (14.1 bis 14.n) unter Echtzeitbedingungen Zugriff auf den PIMS/DCS-Server (12) und darin gespeicherte Prozesshistoriendaten zu ermöglichen.
摘要:
These and other objectives are attained with a method and system for recording data monitored during the manufacture of molded ophthalmic lenses. This method comprises the steps of identifying a set of process parameters used in said manufacture, identifying an associated value range for each of the process parameters, and monitoring each of the process parameters during the manufacture of the lenses. If, during the manufacture of one of the ophthalmic lenses, one of the process parameters moves outside the associated value range, then that lens is rejected. However, if, during the manufacture of one of the ophthalmic lenses, all of the process parameters stay within their associated ranges, then that lens is identified as acceptable, and a device history record is made for that lens. This device history record includes a reference code for identifying the set of process parameters. A database, referred to as a shadow table, may be used to protect the integrity of data recorded during, or relating to, the manufacture process. In accordance with this feature, a shadow table is formed, and data items from device history records are copied into the shadow table in response to the occurrence of predefined events. For example, these predefined events may include whenever anyone, or anyone outside a group of identified individuals accesses the device history record to perform predefined operations, such as alter or deleted, on the data in the device history record.

There is provided a process management apparatus that allows even a user with a low level of technical skills to accurately and quickly estimate a failure factor when a failure occurs in an object of processing due to a failure of processing in a processing system that performs processing for the object. An estimation processor reads out information on conditions leading to failure factors from an estimation knowledge recording section and presents the conditions to a user as questions in order. Analysis IDs are associated with the respective conditions. A data processor 32 receives analysis ID information of a condition corresponding to a question to read out data collection method information and data processing method information corresponding to a relevant ID, performs analysis in accordance with the data collection method information and the data processing method information, and presents an analysis result to the user.
摘要:
The invention relates to a computer-assisted production tracking system for one or more machines (2, 3, 4), whereby said machines consist of at least one primary real time system (1, 1') comprising at least one input which is connected to at least one machine (2, 3, 4) and/or to at least one secondary real time system (2a, 3a, 4a) of the machine(s) (2, 3, 4) and at least one output which is connected to at least one server (5, 5'). Moreover, the primary (1, 1') and/or secondary (2a, 3a, 4a) real time systems comprise a program which can determine the operating mode of the aforementioned machine (2, 3, 4) and/or the operating time in each of said modes. In addition, the server (5, 5') makes the above-mentioned information available to client computers (6, 7, 8). The invention is characterised in that the primary (1, 1') and/or secondary (2a, 3a, 4a) real time system(s) comprise a program which can (i) allocate a date and a time to each piece of dynamic information received and (ii) record said information in at least one timestamp file (9), such that the server (5, 5') can make said time-stamped information available to the client computers (6, 7, 8).
