Description

technical field [0001] The invention relates to an inclination measurement system, in particular to a wireless inclination measurement system applied to wind power generator tower detection. Background technique [0002] As environmental pollution becomes more and more serious and energy consumption continues to increase, traditional power generation methods such as thermal power generation and hydropower generation are more and more recognized by people as being unfavorable to the environment. New energy such as wind power and solar power is gaining attention from enterprises and governments. Due to the influence of factors such as stratum movement and rock-soil medium complexity, the weight of the tower itself, self-vibration, wind force, blade-chassis-tower coupling and other factors, the tower or tower of the wind turbine will have a Certain offset. When the deviation exceeds the safe range, the tower will cause major accidents such as toppling and endangering the safe...
