Fan signal acquiring device

Abstract

The invention discloses a fan signal acquiring device. The fan signal acquiring device comprises a sensor signal conditioning module, a signal acquiring and processing module and a data communication transmitting module, wherein an analog signal and audio and video signals sent by the sensor signal conditioning module are sent to the signal acquiring and processing module, converted into digital information, preprocessed and then transmitted to a control center through the data communication transmitting module for further analysis processing and failure processing. The signal acquiring device synchronously acquires a vibration signal, a rotating speed signal and a temperature signal of a transmission chain part of a fan through multiple channels of a 16-bit ADC (analog to digital converter) and transmits the signals through the Ethernet and GPRS (general packet radio service), the data transmission timeliness is improved while the acquisition accuracy is improved, audio acquiring and video monitoring functions are added, and a firm foundation is laid for data analysis, noise analysis, state monitoring and fault diagnosis by an upper computer.

Description

Technical field: [0001] The invention relates to a fan signal collector. Background technique: [0002] In recent years, the wind power industry has developed rapidly. With the gradual increase in the capacity of the wind turbine unit and the volume of the nacelle, the height of the hub has also increased. The challenges faced by the wind turbines have also increased. Various mechanical or electrical failures are prone to occur and require frequent maintenance. [0003] Wind turbines have been using planned maintenance for a long time, that is, general wind turbines are routinely maintained after running for 2500h or 5000h. This maintenance method not only consumes a lot of labor for the wind farm inspection personnel, but also has low efficiency and high risk. It also has relatively high requirements for the professional skills of the inspection personnel, and it is impossible to fully and timely understand the operation status of the equipment; The fault cannot be found a...

Problems solved by technology

The condition monitoring and fault diagnosis system of wind turbines is mainly aimed at megawatt-level wind turbines. Due to the late development of the condition monitoring and fault diagnosis system of wind turbines, generally speaking, both in theory and in practical engineering applications , the wind turbine condition monitoring and fault diagnosis system is still in its infancy, and the efficiency is not high
