[0047]SeeFigure 1-2The present invention provides a technical solution: a fault prediction analysis method for industrial production equipment, including the following steps:

[0048]Step S1: Divide the device level and collect operational data; to collect the failure rate, fault category, fault cause of the general equipment; run data for critical equipment, real-time acquisition equipment;

[0049]Step S2: Performing a device failure prediction analysis; step S2.1 on the general device is performed, and step S2.2 is performed on the critical device;

[0050]Step S2.1: Perform a general equipment fault prediction;

[0051]Step S2.1.1: Set the original timing characteristics x(0)= (X(0)(1), x(0)(2), ..., x(0)(n)), using gray system theory to make a weighted accumulation, generate new data sequences: X(1)= (X(1)(1), x(1)(2), ..., x(1)(n)), where0 <α <1 is a distance weight;

[0052]Step S2.1.2: The background value of the GM (1, 1) model is Z(1)= (Z(1)(2), Z(1)(3), ..., z(1)(n)), where Z(1)(k) = 0....

Abstract

The invention discloses a fault prediction analysis method and model of industrial production equipment. The method comprises the following steps of S1, dividing equipment levels and collecting operation data, collecting the fault rate, the fault type and the fault reason of general equipment in each period, and for the key equipment, acquiring equipment operation data in real time, and S2, executing equipment fault prediction analysis. The step S2.1 is executed on general equipment. The invention relates to the technical field of industrial production equipment, and the fault prediction analysis method and model of the industrial production equipment acquire data through an equipment end, then transmit the data to a fault analysis system, and analyze the reason of the fault through the fault analysis system; and then the fault early warning unit receives the fault early warning information and sends an alarm to corresponding personnel and equipment, so that a fault can be quickly andaccurately found, a worker can maintain the fault conveniently, and normal operation of production equipment is prevented from being influenced by the fault.

Description

Technical field[0001]The present invention relates to the technical field of industrial production equipment, and is specifically a fault prediction analysis method and model of industrial production equipment.Background technique[0002]At present, most of the domestic manufacturers of manufacturing companies on the production system and production equipment are still in the level of manual management, especially for the repair of equipment failures, can only take the way of repairing the repair, not only cannot find a hidden danger, but also not to repair timely Low fault overhaul, the overhead is huge, which seriously affects the production efficiency of the enterprise.[0003]Fault Prediction and Health Management System PHM (Prognostic and Health Management) is a valid tool that currently performs device failure and diagnostics. The PHM system can use centralized, decentralized, hierarchical, and predicting through algorithms and models. And management system health status, the mai...
