In domestic and international existing wind power generating set operational process, fan blade Frequent Troubles.It searches to the bottom, on the one hand due to fan blade
Self structure is limited: fan blade is mainly made of components such as shell, webs, fan blade casing part, by two half-shell glue
It closes and constitutes, there is more complex aerodynamics moulding, blade enclosure is supported by web, and undertakes the load of bending suffered by blade
Lotus.The intensity that this glued construction itself has led to blade is lower, and ability of anti-deformation is poor, such as application No. is
201610169477.1 Chinese patent；On the other hand, since Wind turbines local environment is severe: lightning stroke, strong wind, cold, knot
The climatic factors such as ice, will lead to blade glueing material fatigue and blade construction is impaired, result even in leaf abscission, and may
Further cause the major accidents such as tower.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and a kind of wind power generation unit blade is provided and is existed

Interface and the network architecture, by real-time data transmission to Central Control Room or District integrated control room；
(2) Central Control Room or District integrated control room configuration database server, receive the real time data of each fan delivery and storage；
(3) Central Control Room or District integrated control center configuration data analytics server, analyze the data acquired in real time, pass through meter
Distance difference of three blades during a rotation period with tower is calculated, realizes the monitoring analysis and diagnosis of blade；And match
Display systems are set, the initial data and analysis result to monitoring system acquisition are shown.
Furthermore, the data of acquisition and analysis result are shown in the form of web pages.
Compared with prior art, the present invention having the following advantages that and effect:
(1) distance of the real-time monitoring blade apart from tower realizes the deformation analysis in blade rotation process；
(2) by comparison one rotation period in distance of 3 blades apart from tower, realize blade cracking trend trend with
Track；
(3) by comparison distance, blade icing, cracking, fracture diagnosis is realized, realizes the on-line monitoring and analytic function of blade,
The generation of the accidents such as leaf destruction is avoided, ensures safe operation of wind turbine.
