Abstract

The embodiment of the invention discloses an equipment state evaluation method, device and system and a storage medium. The method comprises the following steps: inputting equipment state data added with a normal state label and an abnormal state label into a prediction model to obtain first prediction data and second prediction data; and determining a state prediction value of the equipment according to the error values of the first prediction data and the equipment state data and the error values of the second prediction data and the equipment state data. Through the technical scheme, manualparticipation is not needed for equipment state evaluation; according to the technical scheme, automation and intelligentization of equipment state evaluation are achieved, the accurate index value of the equipment can be obtained, in addition, under the condition that the performance of the equipment changes, the equipment state can be accurately evaluated and monitored through the technical scheme, and the problem that misjudgment is generated through experience rule evaluation is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of equipment monitoring, and in particular, relate to a method, device, system and storage medium for evaluating equipment status. Background technique [0002] At present, enterprises are paying more and more attention to the leanness of production in product production. Enterprises will make optimal decisions based on market, environment, production goals and equipment status adaptability. Among them, whether the monitoring of production system working conditions and equipment conditions is accurate and objective It is very important to the formulation of enterprise production optimization decision-making. [0003] At present, the evaluation of the abnormal operation status of the equipment by the production enterprise mainly depends on the real-time operation sensors, process settings, production load and other parameters of the equipment, and judges the operation status of the equip...
