Abstract
The invention discloses a kind of system and method for stage lamp Double buffer calibration DMX512 data, including reception device, memory, processor and determining device, from DMX512 interface data；The buffer area for defining two reception data is BUFF1 and BUFF2 respectively, and BUFF1 receives the channel data that stage lighting needs, and BUFF2 receives DMX512 data packet；The BUFF2 DMX512 data packet received and DMX512 agreement are compared；If DMX512 data packet and DMX512 the agreement comparison that BUFF2 is received, as a result the channel data of consistent BUFF1 is exported to stage lighting, otherwise the channel data of BUFF1 is deleted, and is received again.The present invention can judge to obtain a reliable data flow by single in insecure transmission so that stage lamp obtain correct lamps and lanterns in unidirectional DMX512 data needed for channel value.
Description
Technical field
The present invention relates to stage lighting data processing technique, in particular to a kind of stage lamp Double buffer calibrates DMX512 data
System and method.
Background technique
DMX512 agreement is that USITT (theater technological associations, the U.S.) develops into and controls from console with standard digital interface
The mode of light modulator.Currently, the Intelligent lamp including various stage effect lamps, light adjusting controller and Computer lamp is all supported comprehensively
DMX512 agreement, dimming lamp realize Digital Control comprehensively, and on this basis, gradually tend to computerized, networking.
In the control technology of light of stage equipment, generallys use DMX512 agreement and fixture is controlled.But by
In the agreement that DMX512 agreement is a kind of one-way transmission data flow, cause data transmission unreliable.
Existing judgement DMX512 data method is that its error rate, this method are reduced by judging multiple data packets mostly
Influence whether the efficiency of stage lamp processing data.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of stage lamp Double buffer calibration DMX512 data system and
Method, without receive multiple DMX512 data can quick detection data correctness, improve the efficiency of stage lighting data processing.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows:
A kind of system of stage lamp Double buffer calibration DMX512 data, comprising:
Reception device: for receiving the DMX512 data packet of DMX512 interface；
Memory: for defining buffer area, buffer area stores DMX512 data packet；
Processor: for exporting and handling DMX512 data；
Determining device: for comparing and judging DMX512 data packet and DMX512 agreement.
A kind of method of stage lamp Double buffer calibration DMX512 data, comprising:
Step S1, from DMX512 interface DMX512 data packet；
Step S2 defines the buffer areas of two reception data, is BUFF1 and BUFF2 respectively, will be in DMX512 data packet
Channel data is stored to BUFF1, and whole frame DMX512 data packet is stored to BUFF2；
Step S3 compares the DMX512 data packet of BUFF2 and DMX512 agreement by determining device,
If result is consistent, processor exports the channel data of BUFF1 to stage lighting, conversely, processor is by BUFF1's
Channel data is deleted, and re-execute the steps S1.
Preferably, the memory size of the BUFF1 is the size of channel number required for stage lighting.
Preferably, the memory size of the BUFF2 is 513 bytes.
Preferably, the DMX512 data packet of the DMX512 interface is the DMX512 data of whole frame.
By adopting the above technical scheme, by defining the buffer area BUFF1 and BUFF2 of two reception data, BUFF2 is for examining
The integrality of measured data, BUFF1 for exporting, without receive multiple DMX512 data can quick detection data correctness, mention
The high efficiency of stage lighting data processing.
