Abstract
The invention provides a multi-output end synchronous communication system of a light control booth, which comprises a main control unit, a display, a peripheral component interconnect (PCI)-recommended standard (RS) 485 conversion unit, a data memory (DMX) output interface and other control systems, wherein the display is connected with the main control unit through a PCI-E bus, and the PCI-RS485 conversion unit is connected with the main control unit through a PCI bus and is connected with the DMX output interface; and the other control systems of the light control booth are connected with the main control unit through Ethernet interfaces. The multi-output end synchronous communication system of the light control booth can bring immediate experience and effects to users, the efficiency of the light control booth is greatly improved, and operators can real-timely control light control equipment and the stage-lighting effect.
Description
Technical field
The present invention relates to lighting apparatus control technology field, particularly a kind of many outputs synchronous communication system of light of stage control desk.
Background technology
Nowadays the raising gradually of the living standard of Along with people's, except the raising of material life, ordinary populace is also more and more walked close in cultural activity, and various stage performance activities also more and more receive people's hobby.Scene light can make the expressive force of stage performance more rich and varied, particularly utilize high-tech control system more stage performance colourful effect is provided.People carry out lighting system control to the Control Software of light control console through the operation of operation interface; Because present console device is more, light controling signal is more, and just there is a problem in this; Be that deviation can appear in the operation interface of light control console and the synchronism of light controling signal output; Deviation can appear in the response that is various light control appliances, has influenced stage effect, and the operator is controlled light of stage in real time.
Summary of the invention
Pin solves the problem in existing the application; The light controling signal that the present invention proposes in a kind of light control console is exported the synchronous control system at (being the output of DMX signal) and light Control Software interface; Be many outputs synchronous communication system of light control console, make all dateouts keep realtime uniform.
For reaching the object of the invention, many outputs synchronous communication system of light control console of the present invention comprises main control unit, display, PCI-RS485 converting unit, DMX output interface and other control system; Said display is connected with main control unit through the PCI-E bus, and the PCI-RS485 converting unit is connected with main control unit through pci bus, and the PCI-RS485 converting unit is connected with the DMX output interface; Be connected through Ethernet interface between the other control system of light control console and the main control unit.
The output of the DMX signal in the light control console, the parts that involve mainly contain main control unit CPU, pci bus, PCI-RS485 converting unit and output board.In many outputs synchronous communication system of light control console of the present invention; At first light Control Software program is sent master signal through main control unit CPU; Arrive the PCI-RS485 converting unit through pci bus; This moment, the bridging chip of PCI change-over panel can convert master signal to the RS485 signal, and the UART interface through chip outputs to the interface chip on the output board, converts the DMX512 signal to; Send to final DMX delivery outlet, the equipment that can receive the DMX signal can be that a light fixture also can be other equipment.
Many outputs synchronous communication system of light control console of the present invention can be brought instant experience and effect to the user, has improved the efficient of light control console greatly, and makes and operating the effect that light control appliance and stage-lighting effect is reached instant control.
Description of drawings
Through the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the present invention will become obvious.Wherein:
Shown in Figure 1 is the composition configuration diagram of many outputs synchronous communication system of light control console of the present invention;
Shown in Figure 2 is the signal graph of many outputs synchronous communication system of light control console of the present invention.
Embodiment
Be illustrated in figure 1 as the composition configuration diagram of many outputs synchronous communication system of the light control console of one embodiment of the invention, it comprises that many outputs synchronous communication system of light control console of the present invention comprises main control unit, display, PCI-RS485 converting unit, DMX output interface and other control system; Said display is connected with main control unit through the PCI-E bus, and the PCI-RS485 converting unit is connected with main control unit through pci bus, and the PCI-RS485 converting unit is connected with the DMX output interface; Be connected through Ethernet interface between the other control system of light control console and the main control unit.
The output of the DMX signal in the light control console, the parts that involve mainly contain main control unit CPU, pci bus, PCI-RS485 converting unit and output board.When light control console of the present invention is worked; At first light Control Software program is sent master signal through CPU; Arrive the PCI-RS485 converting unit through pci bus; This moment, the bridging chip (for example bridging chip XO16PCI954) of PCI-RS485 converting unit can convert master signal to the RS485 signal, and the UART interface through chip outputs to the interface chip (like interface chip MAX1480) on the output board, converts the DMX512 signal to; Send to final DMX delivery outlet, the equipment that can receive the DMX signal can be that a light fixture also can be other equipment.
In the entire work process of above-mentioned specific embodiment, need postpone the device of each several part to take into full account.As shown in Figure 2, wherein pci bus postpones to be 7-11 nanosecond, and it was 5 nanoseconds that the 0X16PCI954 device postpones, and it is 5 microseconds that MAX1480 postpones.The DMX512 signal frequency is 152KHZ, can ignore for the delay of nanosecond.So the time of signal from system transmissions to final DMX delivery outlet for human body sensory, can reach synchronous effect fully 5-6 is delicate.
Many outputs synchronous communication system of light control console of the present invention can be brought instant experience and effect to the user, has improved the efficient of light control console greatly, and makes and operating the effect that light control appliance and stage-lighting effect is reached instant control.
The present invention is not limited to described embodiment, and those skilled in the art still can do some corrections or change, so rights protection scope of the present invention is as the criterion with claims restricted portion not breaking away from spirit of the present invention promptly openly in the scope.
