Embodiment：
To make the object, technical solutions and advantages of the present invention of greater clarity, below by the specific implementation shown in accompanying drawing
Example describes the present invention.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit the scope of the present invention.This
Outside, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring idea of the invention.
As shown in Figure 1-2, a kind of wind-power tower of the present embodiment exempts to climb device people's machine testing controller, including acquisition module,
Control module and communication module, the acquisition module include acceleration/obliquity sensor, weighing sensor and pulse transducer,
The control module is single-chip microcomputer, and the communication module is wireless communication module, the acceleration/obliquity sensor, biography of weighing
Sensor and pulse transducer are connected with single-chip microcomputer respectively, and the single-chip microcomputer connects wireless communication module.
Specifically, control module is STM32L476 single-chip microcomputers, can carry out the floating-point operation ability of complexity, it is possible to achieve
Fast Fourier Transform (FFT)（FFT）And realize digital filter.Acceleration/obliquity sensor uses ADC for 16 resolution ratio
MPU-6050 sensors, can survey acceleration and the inclination angle of three axles.Communicated by IIC interfaces with MCU, at built in motion
Reason data bank realizes attitude algorithm, reduces requirement of the motion process computing to CPU.Pulse transducer, which is arranged on, exempts to climb device handle
Place, in order to prevent the extruding of different pressures from causing measurement error, is employed plus protective layer and anti-interference strong SON1303 sensings
Device.Band logical bandpass filter and operational amplification circuit have been used behind sensor in order to improve signal to noise ratio, has made the signal after amplification
It can be collected well by STM32 A/D modular converters.Weighing sensor model YZC-1616, specified range is 50Kg, is
Reach and exempt to climb device 100Kg load-carrying demands, system is using four identical sensors connection bridge-types, and range is 200Kg, meets system
System is required.Weighing sensor output is analog signal, so needing A/D modular converters HX711 to collect weighing sensor
Analog signal be converted to data signal, can intuitively obtain the weight of people on pedal.
A kind of wind-power tower of the present invention exempts to climb device people's machine testing control method, comprises the following steps：
（1）Exempt to climb device start-up operation, hardware initialization；
（2）Record exempts to climb device initial baseline value；

Specifically, exempt to climb device car body when normally running, what system was gathered periodically exempts to climb the 3-axis acceleration of device car body, inclines
Angle and human pulse.Exempt to climb device and produce in running to vibrate, particularly the acceleration of X-axis is showed clearly, from X
The acceleration of axle is as the riding index of analysis time domain, and for this discrete signal, its kurtosis coefficient is：
In formula：N is sampling number, and X is signal, and E (X) is average, is variance.
In Practical Project, when it is manned exempt to climb device car body rise to 85-100m when, there is high vibration, can allow manipulation
Person feels unusual uncomfortable.Cause this phenomenon main cause：Exempting to climb the long-play of device causes the loosening of some mechanical, makes
Diminish into end restraint power.It will exempt to climb device and be interpreted as compression strut model, this phenomenon is the phenomenon of strut buckling.In engineering, general choosing
Practical problem, its formula are handled with the Euler's formula of compression strut model：
In formula：E is modulus of elasticity, and I is critical pressure, and μ is length factor, and l is length.
As shown from the above formula, when other conditions are constant, l is longer, easier unstability；μ becomes big, and restraining force is smaller.When being
When high-rise vibration occurs for system, system reads current operation height, can calculate μ according to the body weight for measuring people, meanwhile, it is
Ensure personal safety, system avoids high-rise vibrating area, and whether prompting maintenance personnel detection guide rail has loosening.
It is larger by disturbing due to the pulse signal of time domain, for convenience of analyzing, to the FFT functional transformations of time domain pulse signal,
