Technical field

The utility model relates to electronic console, but specifically a kind of novel high speed rotary display screen that is rotated the communication that constitutes color graphics by trichromatic light emitting diode.

Background technology

At present in various display devices, general with the equipment of LED module as graphic presentation, and great majority are to adopt static planar LED dot matrix display, need a large amount of LED to come display text and figure, the display control circuit complexity, the manufacturing cost costliness, power consumption is big during operation, and has problems such as heat radiation is bad, the continuous pictures renewal is slow in one's movements.If show that with static LED multicoloured colour dot lattice figure also must adopt high performance embedded type CPU or DSP, cost is very expensive.And the transmission of the graph text information of LED display is downloaded communication modes and is generally adopted RS-485 interface or RS-232 interface, the interface mode transmission speed of these kinds is slow, its prestissimo can only reach 22.8kbps, the transmission range weak point can only reach 12m-1.2km, and job insecurity, antijamming capability is low, can not realize the download of wireless data, and is very inconvenient in the application of reality.How solving existing static LED display screen cost height, complicated, the static multiple spot matrix LED of LED display module design colored demonstration must be the problem that those skilled in the art thirst for solving with high-speed CPU or DSP (digital signal processing unit) and image, text and data speed of download slowly always, therefore, invent that a kind of simple in structure, transmission speed is fast, the display of stable work in work is highly profitable.

The utility model content

Technical problem to be solved in the utility model is: the defective that exists at existing product, but provide a kind of simple in structure, transmission speed fast, the novel high speed rotating display device of stable work in work communication is with your deficiency of existing product not.

The technical solution of the utility model is achieved in that it comprises motor, is fixed on surface-mounted integrated circuit and LED light emitting diode on the machine shaft, it is characterized in that: surface-mounted integrated circuit is made up of main control chip, driving display chip, storage chip, CAN Bus Interface Chip, main control chip with storage chip, the CAN Bus Interface Chip is two-way is connected, its another output port is connected with the driving display chip, drives display chip and is connected with the LED light emitting diode.The CDMA communication part also is housed on the surface-mounted integrated circuit, and surface-mounted integrated circuit is fixed on the electric machine rotational axis by fastener, and surface-mounted integrated circuit is connected with brush by four pairs of copper rings with power supply and CAN bus interface; The LED light emitting diode of three kinds of colors of RGB is pressed hexagonal angle, arranges respectively to be three rows and to be evenly distributed on the panel of surface-mounted integrated circuit; Motor and surface-mounted integrated circuit are contained in the circular translucent cover.

The utility model utilizes the persistence of vision principle of human eye, adopt a spot of red green blue tricolor LED light emitting diode of rotation to constitute the colour dot lattice figure, surface-mounted integrated circuit with the mode display plane image that rotatablely moves, lively plane picture be can show, literal, still image and animation comprised.Adopt the communication modes of novel CAN bus (control area net bus) and CDMA, can realize the wired or wireless download of high speed of data.The prestissimo of CAN bus can reach 1Mbps, and wired maximum transmission distance is 10 kilometers; The CDMA baud rate is 152kbps, because be wireless mode, transmission range is not limit.The utility model can be converted to computing machine picture formats such as more existing GIF, BMP the video data form of native system, its content displayed can make amendment and upgrade at any time on computers, CAN bus interface by assembly, and the radio CDMA component interface, the data after upgrading are sent to rotation show on the demonstration storage chip of surface-mounted integrated circuit.The utility model adopts the structure of motor-drive circuit plate rotation, when rotating, circuit board forms complete writings and image by the LED luminophor, its display effect is very unique, and owing to use less color LED, the circuit of surface-mounted integrated circuit and rotating mechanism are also fairly simple, its cost is much lower with respect to plane lattice color LED display screen, and can show in large area in the plane and be applicable to industries such as advertisement, decoration by dynamic colour picture.
