Description
Technical field
The present invention relates to LED display technical field, more specifically, particularly to a kind of rotary LED display screen.
Background technology
LED display is widely used to the public places such as advertisement, station, bank, market, and it has, and power consumption is little, the life-span
The advantages such as length, color are good.The luminescent device of existing LED display mainly uses LED flat plate module, such display screen
Mainly having two problems to have much room for improvement: being first that whole display screen is made up of LED module entirely, number of devices is many, cost is high；Separately
Outward, owing to display screen is a plane, LED pixel point has certain visual angle to limit simultaneously, makes the visual range of display screen be confined
To front within the scope of certain, make the information of display screen issue in the application and receive certain space and limit.
Rotary LED display screen solves the problems referred to above, but the universal structure of existing rotary LED display screen is electricity
Machine and rotation pillar display screen.The principle of this rotation sweep: owing to human eye has the characteristic of persistence of vision, when picture is with necessarily
Speed refresh time, it is seen that be exactly continuous print image, television set display use point by point scanning mode, each second picture to be refreshed
50, face (25 frame), is then the picture that a width is complete in human eye, and tradition LED display typically uses 1/16 scanning, 16 row
Circulate line by line and light, owing to refresh rate is sufficiently large, it is seen that be also the picture of a web stabilization.Its principle signal such as figure
Shown in 1, wherein (a), (b), (c), (d), (e) are display state the most in the same time respectively, and (f) is the complete picture that people arrives soon
“3”.In this LED display, using transposition line by line and move down the scan mode lighting device, each provisional capital must have
Light-emitting diode display part, this just makes the cost of display screen bigger than normal.
Rotary scanning mode display only has string, and by driven by motor, it rotates, and runs to during a certain position the most aobvious
Show the state of this position, after the next position, show again the state of the next position, i.e. string display device all images to be completed
Display, scanning process by mechanical rotation change position realize.Its displaying principle is as shown in Figure 2.Figure a) b) c) is different
The display state in moment, d) is the complete picture " 3 " seen of human eye.
In the design process, center of gravity regulation is a most difficult sport technique segment to rotary LED display screen, the center of gravity of rotation
It is directly connected to stable operation and the safety issue of system.If the center of gravity rotated is not in rotating shaft, in rotation at a high speed
In Zhuaning, violent shake can be produced, under huge centrifugal force, whole system can be made to decompose, produce potential safety hazard.Prior art
In commonly used be discoidal circuit board, but, due to the encapsulation of electronic device, weight is all different, disk circuit
The center of gravity of plate is uneven distribution, relatively difficult regulation.For this reason, it is necessary to design a kind of improvement, center of gravity can be made more stable
Rotary LED display screen.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the rotary LED display screen that center of gravity is more stable can be made.
In order to achieve the above object, the technical solution used in the present invention is as follows:
A kind of rotary LED display screen, rotates pillar display screen, rectangular circuit board, rotating shaft and motor including LED,
Described LED rotates pillar display screen and is located at the middle position of rectangular circuit board, and described motor passes through rotating shaft and rectangular circuit
The bottom of plate connects, and is packaged with LED drive module in the side of described rectangular circuit board, at the opposite side of described rectangular circuit board
It is packaged with the second microcontroller and the second wireless transceiver, is provided with interconnective first micro-control in the side of described motor
Device processed and the first wireless transceiver, wherein said first wireless transceiver and the second wireless transceiver wireless connections, described second
Wireless transceiver and the second microcontroller connect, and described second microcontroller is connected with LED drive module, and described LED drives mould
Block rotates pillar display screen with LED and is connected；And second the weight sum of microcontroller and the second wireless transceiver be multiplied by rotating shaft extremely
The distance of rectangular circuit board one end is multiplied by rotating shaft to the distance of the rectangular circuit board other end equal to the weight of LED drive module.
Further, described first microcontroller and the first wireless transceiver are encapsulated in a circuit board.
Further, described circuit board 8 is additionally provided with the keyboard being connected with the first microcontroller.
Compared with prior art, it is an advantage of the current invention that: the present invention uses rectangular circuit board, when circuit-board laying-out,
Can conveniently ensure the rotating shaft position of centre of gravity just to rectangular circuit board, it is to avoid produce rotation when rotated, make rotation more stable.
