Technical Problem

[0004]随着数据分析和智能化管理的发展，在日常应用中需要对节能电力设备数字化管理，避免设备出现故障影响工厂效率，但是现有的监测管理办法仍有不足，不能基于设备的参数进行监测分析，此外没有考虑设备所处区域的环境因素，分析结果存在局限性

Benefits of technology

[0064] This invention provides a standard digital fault early warning method, device, and system for energy-saving power equipment. The fault early warning method integrates equipment operating parameters and environmental parameters during early warning analysis. The equipment operating parameters mainly include the equipment's output frequency and vibration parameters, while the environmental parameters mainly consider the temperature and humidity of the area where the equipment is located. An operational early warning assessment index and an environmental early warning assessment index are calculated based on the operational and environmental parameters, respectively. Then, a weighted average of these two indices is used to calculate the equipment's early warning level assessment index. The fault early warning method provided by this invention comprehensively considers both operational and environmental parameters, improving the comprehensiveness and accuracy of fault early warning analysis. By determining the equipment that may experience faults and requires handling, as well as the early warning level of the plant area, based on the early warning level assessment index, it helps to improve the speed of handling equipment faults within the plant area.
