Abstract
The utility model discloses a wind power experiment table accelerator noise detection system, and the system comprises an industrial control computer, an ethernet gateway module, a data acquisition module, and sensors, wherein the industrial control computer is connected with the ethernet gateway module, the ethernet gateway module controls the data acquisition module to collect data through the sensors, and the collected data is converted into digital signals; and the digital signals are sent back to the industrial control computer for processing through the ethernet gateway module. The wind power experiment table accelerator noise detection system reduces wind machine operation maintenance expenses through carrying out state detection to the accelerator, service life, operation efficiency, and reliability of the wind machine are improved, and economic benefit and competitive strength of an enterprise are improved.
Description
Technical field
The utility model relates to technical field of wind power generation, is specifically related to a kind of wind-powered electricity generation experiment table booster engine walkaway system.
Background technology
The wind power speed-increasing machine is as the important component part of wind generator system, and its vibrational state directly affects the runnability of wind energy conversion system.Thereby the vibration noise state of detection wind power speed-increasing machine, significant to the stable operation that guarantees the wind power speed-increasing machine.
Equipment diagnosis techniques mainly is exactly that whether by various monitoring meanss, it is normal to differentiate its work in order to satisfy the needs of predictive maintenance; If undesired, with judgement, point out trouble location by analysis, failure cause is convenient to managerial personnel's maintenance; Perhaps before fault does not occur, point out the forecast that may break down, be convenient to managerial personnel and take measures as early as possible, avoid breaking down.Gear case by gear, transmission shaft, bearing, and the parts such as casing form.Since make and assembling process in exist the impact that the external factor such as error and load change, they will produce when work and vibrate while radiated noise in the air.This noise is comprised of two parts: a part is that the noise that part produces in the casing is radiated the air-borne sound that forms in the air by casing: another part is that casing is encouraged the solid-borne noise that produces vibration radiation in the air.Air-borne sound and solid-borne noise have consisted of the overall noise of gear case.
The utility model content
For above-mentioned prior art, the technical problems to be solved in the utility model is: the wind power speed-increasing machine is carried out walkaway, grasp its moving law.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
Wind-powered electricity generation experiment table booster engine walkaway system, it is characterized in that, comprise industrial computer, ethernet gateway module, data acquisition module and sensor, described industrial computer links to each other with the ethernet gateway module, ethernet gateway module controls data acquisition module passes through the sensor image data, and the data that collect are converted to digital signal; Digital signal is transmitted back to industrial computer through the ethernet gateway module and processes.
Described sensor comprises current vortex speed pickup, sound pressure sensor and vibration acceleration sensor.
Described digital signal is generted noise examining report and vibration detection report after industrial computer is processed.
Compared with prior art, the utlity model has following beneficial effect:
Reduce the wind energy conversion system operation expense by booster engine being carried out state-detection, improve serviceable life, operational efficiency and the reliability of wind energy conversion system, improve economic benefit and the competitive strength of enterprise.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
Wind-powered electricity generation experiment table booster engine walkaway system, comprise industrial computer, ethernet gateway module, data acquisition module and sensor, described industrial computer links to each other with the ethernet gateway module, ethernet gateway module controls data acquisition module passes through the sensor image data, and the data that collect are converted to digital signal; Digital signal is transmitted back to industrial computer through the ethernet gateway module and processes.Described sensor comprises current vortex speed pickup, sound pressure sensor and vibration acceleration sensor.Described digital signal is generted noise examining report and vibration detection report after industrial computer is processed.
Data acquisition module is responsible for the sensor die analog signal through pre-process is converted to the digital signal that computing machine can receive, and the frequency of what and sampling of sampled data output is by the industrial computer software control.Be provided with the signal preprocessor in the data acquisition module, its effect is that the signal to sensor carries out pre-service, is converted to voltage and noise etc. is removed in pre-filtering such as the quantity of electric charge that sensor is produced.Data acquisition module control sensor image data is imported the data that collect into industrial computer, does data analysis by corresponding software.
