Method and system for early warning of failures of air compressor applied to chip production, as well as relative device

Abstract

The application discloses a method and system for early warning of failures of an air compressor applied to chip production, as well as a relative device. The method comprises the following steps of obtaining historical observation vectors of the air compressor, wherein the historical observation vectors comprises monitoring data of various variables; separating the historical observation vectorsinto a first historical observation vector and a second historical observation vector, establishing a failure early warning model through the first historical observation vector, and determining failure early warning thresholds according to the failure early warning model and the second historical observation vector; obtaining actual observation vector of the air compressor; judging whether the failure early warning condition is met or not through the failure early warning model and the failure early warning thresholds; and if yes, generating an early warning signal. According to the method disclosed by the invention, when the situation that the actual observation vector meets the early warning condition is judged, the failure early warning signal is generated, so that in-site workers areenabled to find early-stage omens of the failure of the air compressor in advance, and adopt right measures to reduce the damages of the failure, so that the safety and economic efficiency of the starting production course are greatly improved.

Description

technical field [0001] The present application relates to the field of air compressors, in particular to an air compressor failure warning method, system and related devices applied to chip production. Background technique [0002] The air compressor is a rotating machine with a complex structure, and it has a high probability of failure. Once a failure occurs, it will have an adverse effect on the economy and safety of the pneumatic production process. In terms of economy, the failure of the air compressor will cause the pneumatic production equipment to lose its power source, resulting in production shutdown, resulting in a significant reduction in corporate profits. At the same time, the maintenance cost of the air compressor is relatively high, and once a failure occurs, it will further increase the operation and maintenance cost of the enterprise. In terms of safety, the air compressor is a high-speed rotating mechanical device. The air storage tank has a high pressure...

Problems solved by technology

[0002] The air compressor is a rotating machine with a complex structure, and the probability of failure is high, and once a failure occurs, it will have an adverse effect on the economy and safety of the pneumatic production process

In terms of economy, the failure of the air compressor will cause the pneumatic production equipment to lose its power source, resulting in production shutdown, resulting in a significant reduction in corporate profits

At the same time, the maintenance cost of the air compressor is relatively high, once a failure occurs, it will further increase the operation and maintenance cost of the enterprise

In terms of safety, the air compressor is a high-speed rotating mechanical device. The air storage tank has a high pressure due to the compressed air stored. When a fault occurs, major safety accidents such as high-speed throwing of components or cylinder explosion are likely to occur, which poses a serious threat On-site staff life safety

However, at present, there is no air compressor failure warning scheme for chip production, so that on-site staff can find early signs of air compressor failure in advance and take correct measures to reduce failure losses
