Abstract

The invention discloses a fan energy consumption monitoring method and system. When a training sample in obtained, energy consumption of a fan is increased by artificially making various faults, the energy efficiency detection method and system specified by the national standard of China are adopted to test the added values of energy consumption of the fan under various faults, the values of increased energy consumption caused by different faults are classified, a vibration characteristic sample and a track characteristic sample are combined to serve as the training sample of a neural network, and a higher space multi-weight neural network is built. In all-weather energy consumption monitoring, only a low-cost three-shaft acceleration sensor and an eddy-flow sensor need to be additionally installed on the fan, three-dimensional vibration signals and shaft center orbit feature vectors are input the multi-weight neural network, and different types of network output are energy consumption addition classifications.

Description

technical field

[0001] The invention relates to a method and system for monitoring fan energy consumption. Background technique

[0002] Fans, motors, pumps, and compressors are collectively referred to as "industrial motor systems" by the International Energy Agency (IEA). The National Development and Reform Commission pointed out in the "Eleventh Five-Year" energy-saving plan that industrial motor systems are the main power users in China, accounting for more than 50% of the total electricity consumption, of which the electricity consumption of fans accounts for 10.4% of the country's electricity consumption. Therefore, the improvement of fan efficiency is of great significance to saving electric energy.

[0003] The fan system has a large volume and a wide area, and the potential for power saving is huge. The promulgation of the national standard "Energy Efficiency Limits and Energy Efficiency Grades of Fans" stipulates the energy efficiency grades, energy efficiency li...
