Color switching control method for stage light and control device thereof

Abstract

The invention relates to a color switching control method for a stage light and a control device thereof. The control device comprises a computer, a signal converter, at least a power supply distributor and at least a target color changing device. The control device is characterized in that control software running in the computer edits the working parameter of each target color changing device, and completes the resetting to the working parameter of each target color changing device through the signals output and received by the signal converter at different times; in a similar way, through the signals output and received by the signal converter at different times, the inquiry of the working parameter and the status parameter of each target color changing device is completed, and the status control of the target color changing device is completed through the control signals output by the signal converter. The target color changing device in the application system can be dynamically managed through the software running in the computer and the signal converter, parameter setting and control data with different features can be used and the control details can be flexibly allocated according to different program demands, thereby effectively reducing the labor expense when the control details are required to be changed, compressing the construction period and greatly reducing the construction cost.

Description

technical field [0001] The invention belongs to the field of lighting effects applied to studios or stages, in particular to a method and control device for controlling color change of stage lighting, including pre-setting color change control and performing color change according to color change control requirements. Background technique [0002] In the current field of studio or stage lighting effects, various color-changing systems are widely used. The purpose is to create colorful lighting effects on the performance site without adding or changing the type of light source. In order to produce lighting effects that meet the requirements at a lower cost, studios / halls, theaters, theaters, etc. of TV stations generally adopt the method of adding cheap color changers at the light sources (lamps), and make the color changers choose different colors through control. Colored paper, using a light source to produce various beams that meet the color requirements. In the current c...

Problems solved by technology

In the current color changing system, the control device can edit and output the control data in DMX512 format, the online device can complete the forward transmission of the control signal, and the color changer can receive the DMX512 format data that meets the setting conditions according to its own parameter settings. Perform the required color change action after controlling the data, but the premise is that the various working parameters of the color changer must be set in advance, and after setting, they cannot be changed flexibly according to actual needs. To change any one of any color changer in the application system The setting of parameters requires a lot of engineering work to cooperate with

On the other hand, since the information exchange mechanism between the control device and the color changer is not defined, the information of any target color changer in the application system cannot be obtained in real time on the control device side, such as: the number and distribution of color changers in the application system , specifications, parameter setting content, working status, whether the color paper needs to be replaced, etc., so that the color change control implemented on the control device actually has a blindly controlled color, even if the color changer that requires the control is not normal due to failure Controlling cannot be reflected in the control equipment. Only through actual control can the failures that cannot be controlled be manifested.

In practical applications, when the desired color changer is controlled but the target color changer cannot be controlled, it will seriously affect the control effect and destroy the atmosphere of the performance
