Description
Technical field
The present invention relates to a kind of semiconductor lighting control system, refer in particular to the dynamic display effect of display screen that a kind of raising is combined into by the LED lamp, improve the control system of refresh rate.
Background technology
The LED light-emitting diode is as a kind of novel light emitting semiconductor device; it is abundant to have color; low in energy consumption; the characteristics that life-span is long; the conventional display screen that is made of the LED light-emitting diode has been applied in the various occasions that need picture and text to show widely; their structure is placed on the bottom line by a plurality of LED light-emitting diodes and is combined into display matrix; make the display screen of an integral body mostly; development along with the urban architecture brightening; occurred a plurality of independently LED lamps are distributed in than on the much bigger area of conventional display screen; the whole exterior wall in a building for example; realize the display effect that conventional display screen is the same in the hope of using lower cost; but the LED lamp of combination can only show several simple change color so at present; formed display screen even adopt these several simple colors; change also very slow; do not reach the dynamic effect of display image and literal, can't contrast with the display screen of routine.This be because, with the each second is example, each LED lamp is by red, blue, the LED light-emitting diode of green three primary colours constitutes a display pixel point, every kind of primary colours are controlled by the view data of 8bit (character), need 24bit (character) to describe a pixel altogether, display screen with a routine is an example, conventional display screen constitutes (768 row * 1024 row) by 786432 pixels, show that so a frame needs 18874368bit (character) view data to describe, persist the time according to human visual, at least show that 24 frames just can reach animation effect each second, so, the transmission medium image transmitted each second data volume that connects between LED lamp and the LED lamp is 452984832bit/ second (18874368bit * 24 frames), about 432 megabit per seconds of baud rate, with prior art, such transmission rate can't realize.
Summary of the invention
The objective of the invention is to overcome the deficiency that above-mentioned prior art exists, and a kind of semiconductor lighting control system simple in structure, easy to use is provided.Display system of the present invention and the LED display of the above are different, mainly connect by transmission signal vector and be combined into a lighting display system by a plurality of LED lamps, the LED lamp is made of one or more LED light-emitting diodes, adopt transmission signal vector to be connected between LED lamp and the LED lamp and be distributed in lighting display system of formation on the very big space, for example be distributed in the exterior wall in a building, such lighting display system not only can reach the effect of urban architecture brightening, can also reach the commercial effect of display text or image, have advantages of high practicability.
In order to achieve the above object, the technical solution used in the present invention comprises: master control part, transmission medium, branch control part, LED lamp are formed, and master control partly partly is connected with each minute control by transmission medium, and each divides control partly to connect the LED lamp respectively.Form native system by above-mentioned each part, can realize view data generation, image data transmission and view data recovery.
Described view data generates, image data transmission partly is based on software and realizes, the display image data that will transmit is combined into a packet with each frame image data that each LED lamp shows by DISPLAY ORDER by software, write and the corresponding address code of LED lamp to packet simultaneously, be used to identify the packet of each lamp, partly the packet of each lamp utilized transmission medium to be transferred to memory in the branch control partly of each correspondence one by one by master control then;
Described view data is restored, be to divide in the control partly at each a memory is all arranged, be used for storing the view data that transmits, when showing, master control partly adopts the view data frame number of the required demonstration of broadcast mode synchronized transmission to divide control partly to each, the color that each divides control partly to extract the view data of storage and control the LED lamp according to view data according to the frame number of receiving, transmission medium is not transmitting color data in procedure for displaying, only transmission shows the instruction of the view data of which frame about needs, like this, the required transmission speed of bearing of transmission medium reduces greatly, adopts conventional transmission medium can reach stable image data transmission and view data and restores.
Described transmission medium can adopt wired, wireless mode, as existing RS485, RS422 or CAN interface, also can adopt radio frequency, infrared interface or the like.
Adopted system of the present invention, the image transmitted data volume is lacked several magnitude than prior art, and image refresh rate reached for 300 frame/seconds, and entire display screen animation smoothness, literal are clear.Such lighting display system not only can reach the effect of urban architecture brightening, can also reach the commercial effect of display text or image, has advantages of high practicability.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation
Embodiment
The invention will be further described especially exemplified by a preferred embodiment below, as shown in fig. 1, the present invention is made up of master control part 1, transmission medium 12, branch control part 10, LED lamp 11, master control part 1 passes through transmission medium 12 and each minute control part 10 is connected, and each branch is controlled part 10 and connected LED lamp 11 respectively.Each LED lamp 11 is made of one or more LED light-emitting diodes.With the known LED display of industry is example, be provided with 1024 LED lamp Unit 11 on abscissa M, be provided with 768 LED lamp Unit 11 on ordinate, display screen constitutes (768 row * 1024 row) by 786432 pixels, do not provide fully in the accompanying drawing, replace with ellipsis.By background technology as can be known, show that a frame needs 18874368bit (character) view data to describe, persist the time according to human visual, at least show that 24 frames just can reach animation effect each second, so, the transmission medium image transmitted each second data volume that connects between LED lamp and the LED lamp is 452984832bit/ second (18874368bit * 24 frames), about 432 megabit per seconds of baud rate.The present invention is combined into a packet with each frame image data that each LED lamp 11 shows by DISPLAY ORDER by software with the above-mentioned display image data that will transmit, write and the corresponding address code of LED lamp to packet simultaneously, be used to identify the packet of each lamp, then by master control partly 1 packet with each lamp utilize the partly memory on 10 of branch control that transmission medium 12 is transferred to each correspondence one by one.Each divides on the control part 10 all a memory, be used for storing the view data that transmits, when showing, master control part 1 adopts the view data frame number of the required demonstration of broadcast mode synchronized transmission to divide control part 10 to each, the color that each divides control part 10 to extract the view data of storage and control LED lamp 11 according to view data according to the frame number of receiving, transmission medium 12 is not transmitting color data in procedure for displaying, only transmission shows the instruction of the view data of which frame about needs, like this, transmission medium 12 required transmission speeds of bearing reduce greatly, the view data of playing 24 frames with per second is an example, the words that we come the serial number of descriptor frame with the view data of 32bit (bit), per second image transmitted data only are 768bit bit (24 frames * 32bit) that is to say, baud rate is 768 bps, well below 432 megabit per seconds, adopt conventional transmission medium 12 can reach stable image data transmission and view data and restore.
Above-mentioned is for example in order to further describe the present invention, to be not limited thereto, and all drops in the claim scope based on the various variations of principle of the present invention.
