SI1-SI4；The E interface of four pieces of LED light stripe boards 14 is respectively E1-E4；So, four pieces of LED light stripe boards 14
SCK interfaces, RCK interfaces, E interface, SI interfaces, SCLR interfaces are entered by two pieces of model 74LS245 bus driver respectively
After row electric current drive amplification and bus marco selection and impedance matching, the first MCU1 11 I/O ports are accessed；First MCU1 is used for
According to required display Current Content, LED light stripe board 14 is turned off or on by controlling E1-E4.SI1-SI4 is used respectively
To control the information such as the display content of corresponding LED light stripe board 14.The present apparatus is not restricted to indicate using four pieces of LED
The setting structure of lamp stripe board 14, also can be through using the setting structure with one piece of LED light stripe board 14, or two pieces
The setting structure of LED light stripe board 14, or the display structure of three pieces of LED light stripe boards 14.
Further, as shown in figure 3, LED driver 6 also includes two model 74LS245 bus driver, first
MCU1 is electrically connected with by 11 I/O interfaces and two bus drivers；Believed by the first MCU1 to bus driver drive control
After number, after two bus drivers carry out Current amplifier and bus marco, four LED light stripe boards 14 are controlled to press respectively
Pictorial pattern preset value scheme is shown.
In the present embodiment, the first MCU1 drives LED light 14 principle of luminosity of stripe board as follows：96 high electricity is undergone again
After ordinary mail number, the first MCU1 will input 96 serial datas to LED light stripe board 14, and carry out 96 displacements；Then, lead to
Crossing the first MCU1 control RCK interfaces makes it export high level, so that the data in data buffer are on each LED lamp bead row
96 LED lamps driving display.The closing and unlatching of each LED are controlled by the first MCU1, so as to show at different moments, no
With the pictorial pattern or text information of scheme of colour；Herein, the vision for also using the about 0.2S as possessed by human eye is temporary
The time is stayed, therefore by human eye vision persistence effect, 4 LED light stripe boards 14 is rotated in 0.2S, make it in 0.2S
Color, brightness and the content of each point in circular planer area are shown, and controls LED driver 6 to be repeated several times by the first MCU1
Content-data is exported to refresh the content for needing to show.
In the present apparatus, LED driver 6 can also use in addition to using model 74LS595 shift registers
74LS573 chips, also each LED can be adjusted by increasing by 64 10R-10K Ω resistance in LED light stripe board 14
Luminosity.
In the present apparatus, each LED light stripe board 14 employs 64 RGB lamp beads, and so, the present apparatus employs altogether
256 RGB lamp beads, and realize that seven colour display screens show by 256 RGB lamp beads, its displaying principle is as follows：In a certain particular moment
Point, red (R) LED, green (G) LED, indigo plant (B) LED for controlling 256 RGB lamp beads respectively by the first MCU1 light；
When individually being lighted by controlling three-primary color LED lamp, it shows corresponding monochromatic light respectively；If the LED two-by-two in RGB lamp beads is simultaneously
It is lit, then yellow purple blue or green three kinds of colors occurs；As three LEDs in RGB lamp beads are lit simultaneously, then there is white, so as to
Whether realize that different pixels point position is not in plane in the conducting for controlling 256 RGB lamp beads by the first MCU1 at different moments
The control of same color (the purple bluish white totally seven kinds of colors of red, green, blue and yellow).By human eye vision persistence effect, in whole circular flat
Each pixel is constantly lighted, is shown on cycle wheel so as to carrying out the contents such as colorful pictorial pattern word video
Effect.
Wherein, first memory 2 is used for storing GPS position information, external environment monochrome information, the first battery electric quantity letter
Breath, electronic lock status information, Bluetooth pairing information, User Defined or remote server show the figure such as figure needed for sending
The information such as case, and above- mentioned information can be uploaded in remote server through long range wireless communication module 32 and stored.
In addition, optical sensor 5 is used to detect external environment condition brightness.First power supply management of charging and discharging module 7 is used for realizing
Low power-consumption intelligent electric energy management, it mainly (reaches certain when optical sensor 5 detects that external environment illumination intensity is excessive
Threshold value) when, the first power supply management of charging and discharging module 7 is controlled by the first MCU1 to cut off LED driver 6, RGB controllers 3, suddenly
The power supply of your sensor 11, the first close range wireless communication module 12 etc., so as to extend the cruising time of the first battery as far as possible,
And when detecting that bicycle remains static, the first MCU1 can also control the first power supply management of charging and discharging module 7 to cut off LED
The power supply of driver 6, RGB controllers 3, Hall sensor 11, the first close range wireless communication module 12 etc., the first MCU1 also will
Into low-power consumption standby pattern, when detecting cycling, the first MCU1 is called out from low-power consumption standby mode state automatically
Wake up, into normal mode of operation.Hall sensor 11, RGB controllers 3, LED driver 6 are opened simultaneously, and passes through the first MCU1
Three switching tubes are controlled to control the color display information of required display pictorial pattern at different moments, passes through the first MCU1 and controls
LED driver 6, the content of required display pictorial pattern at different moments is realized by serial mode, in human eye vision persistence effect
In the presence of, vision can retain different colours scheme of colour, the pictorial pattern dynamic or static state display of different content different colours
Information, so as to realize that the movement dynamically of colorful figure pattern is shown.
Further, only when extraneous environment illumination intensity is less than predetermined threshold value, the first MCU1 can just be controlled the present apparatus
The power supply that first power supply management of charging and discharging module 7 opens the modules such as Hall sensor 11, RGB controllers 3, LED driver 6 supplies
Give, further to save electric energy, realize the transmission of data by a period of time is opened at regular intervals, after end of transmission from
It is dynamic to be closed.In addition, to reach display optimum efficiency, extraneous intensity of illumination is detected in real time by optical sensor, and pass through the
One MCU1 control LED drivers 6 realize the display brightness of LED in LED light stripe board 14 automatically, while are added by three axles
Velocity sensor is available from riding speed of driving a vehicle, and the first MCU1 controls LED driver tablet pattern according to bicycle speed
The speed of pattern data, so as to realize that mobile display speed is adapted with cycling speed.
LED display lamp stripe boards only have one, and fixed with cycle wheel, the present apparatus substantially pictorial diagram is as follows：Will
The present apparatus is tied up (fixed or embedded) and moved on cycle wheel, and with wheel.
Because present apparatus LED display effect is closely related with extraneous intensity of illumination, to prevent under daytime sunlight strong,
LED show do not know caused by energy loss, the present apparatus by optical sensor 5 detect current light brightness, only in the external world
When environment illumination intensity is less than predetermined threshold value, the first MCU1 can just control the first power supply management of charging and discharging module 7 to open LED drivings
