Abstract

The invention relates to the special device maintenance technology field and particularly relates to a method and system for monitoring field maintenance of a special device. The method comprises steps that A1), target special device file data is synchronized to the field device; A2), maintenance project monitoring starts, the field device begins collecting field data, ongoing maintenance projectsare identified, and whether the ongoing maintenance projects are proper-process maintenance projects is determined, if yes, the field data are continuously collected till the maintenance projects arecompleted, if not, a warning is issued, and this step restarts; and A3), data interaction between the field device and a big data server is carried out. The method is advantaged in that 1, project level monitoring in the project maintenance process can be carried out, the amount of monitoring data required for analysis is reduced, and monitoring efficiency is improved; and 2, field data collection items are added in the maintenance project monitoring process, and training data is provided for a neural network model.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance, in particular to a monitoring method and system for on-site maintenance of special equipment. Background technique [0002] Special equipment refers to boilers, pressure vessels, pressure pipes, elevators, hoisting machinery, passenger ropeways, large amusement facilities and special motor vehicles that involve life safety and are relatively dangerous. When special equipment breaks down, it is very easy to cause personal injury to uncertain personnel, and even serious fatal accidents. Therefore, it is necessary to ensure the safe and stable operation of special equipment. For this reason, the state has strict regulations on all kinds of special equipment from the three links of production, use, inspection and testing, and implements full-process supervision and mandatory maintenance. At present, the quality inspection of special equipment in the production stage is relatively comp...
