Description
Technical field
The utility model relates to a kind of racemization instrument, especially a kind of novel racemization instrument.
Background technology
Servo Rotable Control System is complicated, instability a, nonlinear system.Be applied to control theory teaching for a long time and carry out in various Control release, many typical problems in control can be solved to this systematic study: as nonlinear problem, robustness problem, servo-actuated problem and tracking problem etc.Its control method comes into one's own in military project.Adopt traditional mode, in the unrestricted situation of volume, precision is general higher, and namely select the optical fibre gyro diameter of medium accuracy all at more than 80mm, the general diameter of motor, also at about 100mm, can meet the demands.The various factors such as volume, size will be considered at military industry field.First want cube little, within maximum height limit 30mm, the optical fibre gyro of generally applying in this case, motor all can not meet the demands.
Utility model content
The utility model provides the novel racemization instrument that a kind of volume is little, cost is low.
Realize the novel racemization instrument of the utility model object, comprise holder, be arranged on the shell on holder, be arranged on the top cover of cover top portion; Described holder is provided with motor fixing plate, is fixed with motor below described motor fixing plate; Be provided with circuit board above described motor fixing plate, described circuit board is provided with code-disc, and described code-disc both sides are respectively equipped with an optoelectronic switch; Described code-disc is provided with gyro, and the output shaft of described motor is by shaft coupling connection slip ring, and described slip ring is positioned at above code-disc; Described optoelectronic switch is provided with groove, and described code-disc is positioned at groove, and described code-disc excircle is provided with equally distributed little tooth.
The thickness of described code-disc is 0.1mm.
The little tooth of described code-disc excircle is 400.
The beneficial effect of novel racemization instrument of the present utility model is as follows:
Novel racemization instrument of the present utility model, volume is little, and cost is low, dual signal recognizer is the various problems effectively avoiding occurring in signal processing, can realize high-precision signal to export, corner accuracy can ensure, the racemization instrument system effectively ensured is to the requirement of precision.Product is under full temperature change to select the optoelectronic switch of band groove to ensure, system stable output.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel racemization instrument of the present utility model.
Embodiment
As shown in Figure 1, novel racemization instrument of the present utility model, comprises holder 11, is arranged on the shell 2 on holder 11, is arranged on the top cover 1 at shell 2 top; Described holder 11 is provided with motor fixing plate 9, is fixed with motor 10 below described motor fixing plate 9; Be provided with circuit board 8 above described motor fixing plate 9, be provided with code-disc 6 above described circuit board 8, described code-disc 6 both sides are respectively equipped with an optoelectronic switch 7; Described code-disc 6 is provided with gyro 5, and the output shaft of described motor 10 is by shaft coupling 4 connection slip ring 3, and described slip ring 3 is positioned at above code-disc 6; Described optoelectronic switch 7 is provided with groove, and described code-disc 6 is positioned at groove, and described code-disc 6 excircle is provided with equally distributed little tooth.
The thickness of described code-disc 6 is 0.1mm.
The little tooth of described code-disc 6 excircle is 400.
Code-disc is provided with 400 little teeth be evenly distributed in around code-disc.Each gear is through optoelectronic switch, optoelectronic switch will export a signal, the representative of this signal turns over the angle measurement that each gear mesh is answered, in order to ensure the accuracy measured, optoelectronic switch circumferentially lays two whole, carrying out the measurement of comparison of two signals, calculating an angle measurement by comparing.The problem that the larger optical fibre gyro of volume exports high-precision angle value is fundamentally solved like this by the double angle measurement of gyroscope and code-disc.
Gyro senses the angular velocity rotating and produce, this angular velocity signal feeds back to the measuring unit of circuit board, current output and zero-bit compare by circuit board, regulated by PID and a reciprocal moment is exported to motor, the counter motion of excitation code-disc completes racemization action, makes its position keep geo-stationary.Meanwhile, code-disc and optoelectronic switch and the acting in conjunction of coding circuit unit, realize the pulse code of angle and export.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the utility model designs spiritual prerequisite; the various distortion that the common engineering technical personnel in this area make technical solutions of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
