Abstract
The invention discloses a kind of motion control method for shaking lamp, the fifo queue for including the following steps: S1, establishing DMX signal sets queue length；S2, when receiving the DMX signal for carrying out automatic control platform, DMX signal is joined the team；S3, the DMX signal after joining the team is pre-processed, the pretreatment includes discovery halt, finds reversal point, calculate movement velocity, determine whether jump signal；S4, the motor operating parameter for shaking lamp is adjusted according to the pre-processed results of step S3.The method of the present invention prejudges the direction of motion variation of control platform signal designation, velocity variations by the way that DMX signal is buffered and pre-processed, and filters out the signal of mutation, strives for advantage to shake the steady control of lamp motor.
Description
Technical field
The present invention relates to lamps and lanterns control technology fields, and in particular to a kind of motion control method for shaking lamp.
Background technique
In the realization for shaking lamp Pan/Tilt control, need to make the DMX signal for controlling platform response promptly and accurately, and
Driving shake lamp motor is steady, is quickly accomplished corresponding movement.According to the working principle of control platform, even preprogramming
CUE, such as from A point to the uniform motion of B point, control platform also can carry out interpolation processing according to fade time between initial value and final value, often
Frame can only provide next interpolation, that is to say, that lamps and lanterns can not know the real terminal of stroke, thus be difficult to the acceleration to motor,
Slow down and brake is planned in advance, is especially difficult to the case where handling direction of motion reversion.On the other hand, when manpower passes through push rod
Or encoder is when controlling lamps and lanterns, because being easy to generate the irregular control signal of jumping characteristic, mutation, the movement of lamps and lanterns
It controls more difficult, it is easy to the case where leading to " step-out ".
Existing method controls platform signal often through with lower movement velocity to respond, to reserve sufficient " buffering row
Journey " come obtain the time of relative loose braked, the processing such as reversed, respond slow, motion profile deformation so as to cause lamps and lanterns
The problems such as.
Summary of the invention
In view of the deficiencies of the prior art, the present invention is intended to provide it is a kind of shake lamp motion control method, by believing DMX
It number is buffered and is pre-processed to prejudge the direction of motion variation of control platform signal designation, velocity variations, and filter out the letter of mutation
Number, strive for advantage to shake the steady control of lamp motor.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of motion control method shaking lamp, includes the following steps:
S1, the fifo queue for establishing DMX signal set queue length；
S2, when receiving the DMX signal for carrying out automatic control platform, DMX signal is joined the team；If queue full, team's head is popped up；
S3, the DMX signal after joining the team is pre-processed, the pretreatment includes discovery halt, discovery reversal point, meter
It calculates movement velocity, determine whether jump signal, such as find jump signal, then jump signal is filtered or smoothing processing；
S4, the motor operating parameter for shaking lamp is adjusted according to the pre-processed results of step S3.
Further, in step S1, the length of queue is 3.
Further, in step S3, jump signal includes velocity jump signal, reversed reverse signal again.
Further, in step S2, when there is new DMX signal to join the team, if queue full, team's head is popped up.
The beneficial effects of the present invention are: utilize the method for the present invention, it is only necessary to which the DMX signal for buffering a small amount of frame in advance is gone forward side by side
Row pretreatment, can substantially improve the stationarity for shaking lamp motor operation, although buffering will lead to signal, response has certain delay
(according to DMX standard frame per second, delay is about 100ms), but this delay is not easy to discover, especially in successional movement more
Adding can ignore；Simultaneously as there is the pretreatment to signal, it is unknowable to handle reserved too many " cushion stroke " is not needed
Variation, the speed of overall operation are more excellent than conventional method instead.
Specific embodiment
The invention will be further described below, it should be noted that the present embodiment premised on the technical program,
The detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to the present embodiment.
The present embodiment provides a kind of motion control methods for shaking lamp, include the following steps:
S1, the fifo queue for establishing DMX signal set queue length (general 3)；
S2, when receiving the DMX signal for carrying out automatic control platform, DMX signal is joined the team；If queue full, team's head is popped up；
S3, the DMX signal after joining the team is pre-processed:
(1) halt is found；
(2) reversal point is found；
(3) movement velocity is calculated；
(4) it determines whether jump signal, such as finds jump signal (such as velocity jump, reversed reversed again), then to prominent
Varying signal is filtered or smoothing processing；
S4, the motor operating parameter for shaking lamp is adjusted according to the pre-processed results of step S3.
For those skilled in the art, it can be provided various corresponding according to above technical solution and design
Change and modification, and all these change and modification, should be construed as being included within the scope of protection of the claims of the present invention.
