一种消除震动对增量式光学编码器测量影响的方法

Method for eliminating influence of vibration over measurement of incremental

optical encoder

本发明旨在提供一种消除震 动对增量式光学编码器测量影响的方法，

以解决现有技术中增量

式光学编码器抗震能力差的技术问题。

该方法是在现有增量式光学编码器的基础上，

将光学

编码器的光电读头数量增加为四个，

并将四个光电读头沿指示圆光栅盘圆周均匀安置，

使各

读头相对 于圆心成９０度分布。

通过四个读头和ＡＤ转换电路及检相算法将四读头位置处的

叠栅条纹相位解算出来，

再以该四个特定位置的相位信息为基础，

计算出标尺圆光栅盘震动

方向和震动幅度，

从而求出该震动产生的误差项并反代入光学编码器转动引起的叠栅条纹相

位变化表达式，

消除震动的影响。

本发明极大地降低了震动时光学编码器的检相 误差，

提高

了存在震动时光学编码器的测量精度。

The invention aims to provide a method for eliminating the influence of vibration

over

the

measurement

of

an

incremental

optical

encoder,

so

as

to

solve

the

technical

problem of poor anti-vibration ability of the incremental optical encoder in the

prior

art.

The

method

is

characterized

in

that

on

the

basis

of

the

existing

incremental

optical

encoder,

the

number

of

photoelectric

read

heads

of

the

optical

encoder

is

increased

to

four;

the

four

photoelectric

read

heads

are

evenly

settled

along

the

circumference

of

an

indicating

circular

grating

disc;

and

each

read

head

is distributed at an angle of 90 DEG relative to a circle center. Stacked grating

fringe phases in the positions of the four read heads are solved through the four

read

heads,

an

analog- digital

(AD)

conversion

circuit

and

a

phase

detection

algorithm; then the vibration direction and the vibration amplitude of a scale

circular grating disc are calculated on the basis of the phase information of the

four

specific

positions,

so

as

to

determine

error

terms

produced

during

the

vibration;

and the vibration direction and the vibration amplitude are inversely substituted

into an expression of stacked grating fringe phase changes caused by the rotation

of

the

optical

encoder,

so

as

to

eliminate

the

influence

of

the

vibration.

By

adopting

the

method,

phase

detection

errors

of

the

optical

encoder

are

greatly

reduced

during

the

vibration,

and

the

measurement

accuracy

of

the

optical

encoder

is

improved

when

the vibration exists.
