Example Embodiment
[0035] Example 1
[0036] see figure 1 As shown, the present invention is a noise reduction method for a medium voltage uninterruptible power supply device, and this embodiment specifically discloses a classification filtering method:
[0037] Install monitoring equipment and detect synchronization rate: The staff installs the noise monitoring equipment on the uninterruptible power supply device, supplies power to it through the UPS, and adjusts the transmission synchronization of each group of noise monitoring equipment.
[0038] It needs to be further explained that the UPS is specifically an uninterruptible power supply including an energy storage device, which is mainly used to provide uninterrupted power supply to some devices that require high power supply stability.
[0039] Collect and classify the UPS information of each group: collect the relevant data of the UPS in each area, build a classification repository based on the MySql database, and import each group of da...
Example Embodiment
[0042] Example 2
[0043] see figure 1 As shown, the present invention is a noise reduction method for a medium-voltage uninterruptible power supply. Except for the same structure as the above-mentioned embodiment, this embodiment specifically discloses an analysis and adjustment method:
[0044] Collect the noise data of each group of devices for analysis: The server collects the noise data of the running UPS in real time through the noise monitoring equipment, and at the same time analyzes and adjusts the collected noise data of each group.
[0045] Specifically, first, the server builds an optimized learning model, and imports each group of noise data collected by the noise monitoring device into the optimized learning model. The entire data value is divided according to user-defined rules, and the divided data is integrated to generate a noise set S n ={A 1 , A 2 , A 3 ,...,A x }, where n is the total number of noise sets divided, x is the total number of noise data ...

Abstract
The invention relates to a noise reduction method for a medium-voltage uninterruptible power supply device, which belongs to the technical field of noise reduction and comprises the following specific steps of: (1) installing monitoring equipment and detecting a synchronization rate; (2) information of each group of uninterruptible power devices is collected and classified; (3) collecting noise data of each group of devices for analysis; (4) performing noise reduction feedback on each group of devices; by constructing the classification storage library, the missing data can be subjected to supplementary feedback, the integrity of data collection is ensured, meanwhile, the retrieval data set is constructed, the data retrieval efficiency of workers is improved, redundancy screening can be performed on noise data generated by each group of uninterruptible power devices, the accuracy of the collected noise data is improved, and the data retrieval efficiency is improved. The accuracy of the fed-back noise decibel data of each group of uninterruptible power devices is ensured, and a worker can check and analyze the noise decibel data conveniently.
Description
technical field [0001] The invention belongs to the technical field of noise reduction, and in particular relates to a noise reduction method for a medium voltage uninterruptible power supply device. Background technique [0002] The normative usage of noise is noise. From a physiological point of view, any sound that interferes with people's rest, study and work and the sounds that people want to hear, that is, unwanted sounds, are collectively referred to as noise. Noise pollution is formed when adverse effects are caused. In physics, noise refers to all irregular signals, such as electromagnetic noise, thermal noise, noise during radio transmission, laser noise, optical fiber communication noise, and image noise when the camera takes pictures, etc. , Among them, as computer application systems have higher and higher requirements for power supply, uninterruptible power supply devices have gradually attracted people's attention, and are widely used in mining, aerospace, ind...
