Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of equipment management, and in particular relates to a health evaluation method, system, equipment and medium for assembly line equipment. Background Art
[0002] In modern industrial production, the health of specialized assembly line equipment (such as those used for electricity meter calibration) is directly related to production efficiency and product quality. Because these devices operate under constant high load, real-time monitoring and assessment of their health status is crucial. Accurately assessing the health of these devices not only provides early warning of potential failures and avoids unplanned downtime, but also optimizes maintenance strategies, extends equipment life, and reduces production costs. Therefore, scientifically and comprehensively assessing the health of specialized assembly line equipment has become a key scientific challenge in this field. To address this issue, several equipment health management systems have been proposed. For example, Chinese patent CN201910079283.6 proposes an equipment health management system that assesses equipment health status through a data acquisition module, a database module, an environmental parameter module, a data processing module, a comparison module, a health factor module, an algorithm module, and a health analysis module. Specifically, this system collects equipment operating parameters (such as operating time, load, energy consumption, temperature, and vibration) and, combining these with health factors and algorithms, calculates the equipment's health. The health analysis module then outputs the device's health status. However, existing technologies primarily rely on health factors and algorithms to calculate the health status of equipment. While these can partially reflect the operating status of the equipment, they fail to fully consider the multi-dimensional factors of the equipment. Furthermore, existing health assessment models are mostly static models that cannot reflect the health status and failure risks of the equipment under real-time tasks. In summary, existing technologies still have many limitations in assessing the health status of assembly line equipment, especially in terms of the comprehensiveness of the assessment, dynamic assessment capabilities, prediction accuracy, and intelligence level, which need to be improved.
