Embodiment Construction

[0033] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the text of the description.

[0034] It should be understood that terms such as "having", "including" and "including" used herein do not equate the presence or addition of one or more other elements or combinations thereof.

[0035] A method for early warning of equipment operating conditions, the equipment refers to instrumentation and electrical equipment, and the method includes the following steps:

[0036] Step 1. For instruments and meters, directly obtain the detected values ​​and store them in the database. For electrical equipment such as water pumps and fans, the current can be obtained by installing sensors that detect its operating current. Some abnormal data in the monitoring data need to be removed by filtering first to avoid interference with the analysis of volatility.

[0037] Step 2: Calculate the volatility k and the average vo...

Abstract

The invention discloses a method of early warning the operating condition of equipment. The equipment refers to instrument and motor equipments. The method comprises the following steps: intermittently acquiring the data of the equipment with a fluctuation rule; calculating a fluctuation ratio k and a fluctuation ratio mean value p in each step length by using a fluctuation calculating formula and a fluctuation ratio mean value calculation formula; drawing changing curves of the fluctuation ratio and the fluctuation ratio mean value along with time by using the fluctuation ratio and the corresponding fluctuation ratio mean value in each step length in such ways of taking the corresponding fluctuation ratio mean value p as a longitudinal shaft and taking the corresponding time as a cross shaft; calculating the similarity measuring values of the fluctuation ratios k and the corresponding fluctuation ratio mean values p by using a Similar function; giving an early-warning alarm when each similarity measuring value is continuously lower than an alarm threshold. According to the method provided by the invention, no new instrument is additionally arranged for the instrument equipments, so as to realize significant practical meanings on continuously monitoring and timely early warning the equipment, and repairing and maintaining the equipment.

Description

Technical field [0001] The invention relates to an equipment maintenance method. More specifically, the present invention relates to a method for early warning of equipment operating conditions. Background technique [0002] The equipment maintenance system has gone through five development processes: 1) Repair after the event, repair after the equipment breaks down, the equipment will stop for a long time, which may disrupt the production plan; 2) Preventive maintenance, strengthen daily inspections and regular inspections, will make Increased maintenance workload and over-maintenance; 3) Production maintenance, preventive maintenance of key equipment, and post-maintenance of general equipment; 4) Maintenance prevention, which improves equipment reliability and repairability during equipment design and manufacturing stages, and prevents equipment failures in later operation The detection effect is not great; 5) Comprehensive equipment management, mainly based on state maintenan...
