Technical field
The invention belongs to servomechanism technical fields, in particular to utilize light in motor shaft end rotary transformer and receiver
The method of photoelectric coder measurement weapon system transmission backlash.
Background technique
The steering wheel of weapon system, the transmission of motor input shaft to the receiver photoelectric encoder output shaft of elevating mechanism are empty
It returns, directly affects servomechanism control precision, and then influence entire weapon system performance index.Above-mentioned transmission backlash is measured at present
Method be: under motor blocking, do not stop pushing executing mechanism back and forth using manual mode, by reading receiver in real time
The position that interior photoelectric encoder returns calculates the transmission backlash of motor input shaft to receiver photoelectric encoder output shaft, this side
Although method can be measured and be assessed to the transmission backlash between motor input shaft and photoelectric encoder to a certain extent, because accidentally
Difference is larger, can not be undesirable to servomechanism debugging one effective truthful data platform of offer.
Summary of the invention
The object of the invention is in order to overcome the shortcomings of above-mentioned background technique, and provides and a kind of rotated using motor shaft end
The method of photoelectric encoder measurement weapon system transmission backlash in transformer and receiver, rotates transformation by calculating motor shaft end
Photoelectric encoder returns in device and receiver position difference calculates the transmission of motor input shaft to receiver code-disc output shaft
Backlash.
It is involved in the present invention to utilize photoelectric encoder measurement transmission backlash in motor shaft end rotary transformer and receiver
Method, its step are as follows:

2) it completes to communicate debugging between position control case and height driving box, it is ensured that position control case is communicated with height driving box
Link is normal；
3) it completes to communicate debugging between position control case and photoelectric encoder in receiver, it is ensured that position control case and receiver
Communication link is normal between interior photoelectric encoder；
4) sinusoidal signal that a standard is exported by sine mechanism, the input as height driving box is given, to drive height
Low motor does sinusoidal motion；
5) in height motor movement, height driving box completes motor shaft end rotary transformer positional number with the period of 2ms
According to acquisition, and to be timely transmitted to position control case；Meanwhile position control case completes photoelectricity in receiver with the period of 2ms
The acquisition of encoder position data；
6) position control case is receiving photoelectric encoder position in motor shaft end rotary transformer position data and receiver
After setting data, the fusion conversion process of data is completed, a frame data is packaged into, is sent in CAN bus, commissioning staff can lead to
CAN analyzer is crossed directly to analyze data；
7) data are shown, gun turret commutates the moment, and the position data that motor shaft end rotary transformer provides is a standard
Sine curve, and because of the presence of backlash, the position data curve that photoelectric encoder provides in receiver is: first keeping a Duan Shui
It is flat, then keep up with the sine curve that motor shaft end rotary transformer provides.
8) numerical value both when using commutation makes the difference, which is backlash.
Method using photoelectric encoder measurement transmission backlash in motor shaft end rotary transformer and receiver of the invention,
The error for eliminating manual mode measurement transmission backlash provides solid number to servomechanism debugging and transmission system rectification
According to analysis platform.
