Embodiment Construction

[0028] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0029] A method for predicting equipment faults based on point inspection data and DCS online data, characterized in that an equipment maintenance information database is established, and the maintenance information database includes equipment point inspection data, DCS online data and equipment maintenance data, and the Equipment point inspection data and DCS online data are stored in association with equipment maintenance data; and then periodically match the data in the current stage of the equipment with the data in the maintenance information database. When the maintenance data of a certain maintenance match, the equipment is predicted to predict the type of failure and the time of failure according to the data in the maintenance information database; the point inspection data refers to the point inspection and / or inspection process of the equipm...

Abstract

The invention provides an equipment failure prediction method based on point polling data and DCS (Data Communication System) online data, which comprises the steps of: establishing an equipment overhauling information base, wherein the overhauling information base comprises equipment point polling data and DCS online data as well as equipment overhauling data; carrying out relevance storage on the equipment point polling data, the DCS online data and equipment overhauling data; and then periodically carrying out data matching on data of equipment in current state and data in the overhauling information base, when the data of the equipment in the current state are matched with some overhauling data in the overhauling information base, predicting a failure type of the equipment according to the data in the overhauling information base and predicting the failure generating time. With the data accumulation of the data in the equipment overhauling information base, most of equipment failure types are predicted, an effective basis is provided for the predictable overhauling of the equipment and the basic protection is provided for the normal production.

Description

technical field [0001] The invention relates to a method for predicting equipment failure, in particular to a method for predicting equipment failure based on point inspection data and DCS online data, mainly aimed at the prediction of non-sudden and gradual equipment failure. The point inspection data refers to the equipment parameter operation data recorded during the inspection and / or inspection process of the equipment, and the DCS online data refers to the equipment parameter operation data collected in the DCS system. DCS is Distributed The English abbreviation of Control System, DCS system is also called distributed control system or distributed control system. Background technique [0002] In the process of industrial production, the normal operation of production equipment is the basic condition to ensure the smooth progress of production. In order to ensure the normal operation of production equipment, it is necessary to carry out frequent maintenance on the equip...
