Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
embodiment 1
As shown in Figure 1, a kind of bicycle Hot Wheels based on Bluetooth transmission, comprise single-chip microcomputer, arm, LED 11 and the bluetooth module 12 for receiving image data, this bluetooth module 12 is connected with single-chip microcomputer, and single-chip microcomputer and LED 11 are arranged on arm.When these Hot Wheels are arranged on bicycle quick spoke by user, along with vehicle wheel rotation and Hot Wheels run time, single-chip microcomputer read store image data, and control corresponding LED bright/go out, due to persistence of vision principle, people just can see splendid colorful pattern, word, animation, picture.Bluetooth module 12 can make these Hot Wheels can communicate with the external world, and user can use the equipment of band bluetooth to send image data to single-chip microcomputer at any time, makes Hot Wheels show different pictures etc.
As required, it can be 1 ~ 4 by Hot Wheels arm quantitative design.The present embodiment is provided with four arms, even if thus bicycle can be made also to reach extraordinary display effect when the slow-speed of revolution.Each arm comprises tow sides, and can arrange the LED being used for displays image information in one side, also all can arrange on two sides, all can see image like this in car both sides, the present embodiment two sides is equipped with LED.
In order to break through single-chip I/O mouth restricted number, the utility model adds transformation from serial to parallel expanded circuit, the all LED of Hot Wheels all can adopt monochromatic LED lamp, all LED of an arm one side are all connected to an I/O delivery outlet of single-chip microcomputer by a transformation from serial to parallel expanded circuit, this example is owing to have employed four arms, and each arm is two-sided arranges LED, then only need 8 transformation from serial to parallel expanded circuits, and the single-chip I/O mouth related to also only only has 8, because two sides is symmetrical, thus two sides can share a transformation from serial to parallel expanded circuit, so just only need 4 transformation from serial to parallel expanded circuits and 4 single-chip I/O mouths.Adopt monochromatic LED lamp, its transformation from serial to parallel expanded circuit, see Fig. 2, is formed primarily of multiple serioparallel exchange chip, the chip of the present embodiment adopts 74HC 595 serioparallel exchange chip, 74HC595 is the digit chip of transformation from serial to parallel, and a serial port input, eight parallel port export.By three 74HC595 series connection, can realize a pin serial input, 24 parallel port export.We convert the control signal of LED to serial signal, outputted to the serial input pin of 74HC595, finally, convert parallel signal to by 74HC595 by an I/O port of single-chip microcomputer, control all LED on support arm face.An I/O delivery outlet of single-chip microcomputer and the serial input mouth SDI(pin 14 of a 74HC 595 serioparallel exchange chip) be connected, the Serial output mouth SDO(pin 9 of this serioparallel exchange chip) all the other serioparallel exchange chips of connecting successively, be specially, the Serial output mouth SDO(pin 9 of a 74HC 595 serioparallel exchange chip) with the serial input mouth SDI(pin 14 of another 74HC 595 serioparallel exchange chip) be connected.The parallel output mouth (D0 ~ D7) of all serioparallel exchange chips is all for being connected with monochromatic LED lamp.
Owing to arranging transformation from serial to parallel expanded circuit, equal to have rolled up LED interface, thus LED all can be replaced and be adopted RGB three-color LED light, so just can realize the display of colour picture.RGB three-color LED light comprises R look, G look, B color control pin.As shown in Figure 2, the R color control pin of all LED of an arm one side is all connected to an I/O delivery outlet of single-chip microcomputer by a transformation from serial to parallel expanded circuit, this transformation from serial to parallel expanded circuit still forms primarily of 74HC 595 serioparallel exchange chip, an I/O delivery outlet of single-chip microcomputer and the serial input mouth SDI(pin 14 of a 74HC 595 serioparallel exchange chip) be connected, the Serial output mouth SDO(pin 9 of this serioparallel exchange chip) all the other serioparallel exchange chips of connecting successively, be specially, the Serial output mouth SDO(pin 9 of a 74HC 595 serioparallel exchange chip) with the serial input mouth SDI(pin 14 of another 74HC 595 serioparallel exchange chip) be connected.The parallel output mouth (D0 ~ D7) of all serioparallel exchange chips is all for being connected with R color control pin.G color control pin, B color control pin are similar to R color control pin, and are also connected to an I/O delivery outlet of single-chip microcomputer by a transformation from serial to parallel expanded circuit separately.
The embodiment of whole employing RGB three-color LED light is made up of four arms, and each arm has tow sides, and every one side has 24 LED lamps, and each lamp is made up of RGB tri-kinds of colors, can, by regulating RGB tri-look, make LED present arbitrary color.When four arms are arranged on above cycle wheel, and when carrying out high-speed rotation along with wheel, the display data of one width picture be evenly distributed in above the disc of cycle wheel, utilize the vision of human eye to stop effect, the LED lighted can form the stable image of a width colour.
The utility model operationally, single-chip microcomputer exports N number of high/low level signal within a clock period, the sequencing of N number of level signal that 74HC595 receives according to DATAIN pin within a clock period, each level signal is exported by 8 pins successively, locked by LATCH pin simultaneously, allow 8 pins continue to export the signal of one end time.Wherein, single-chip microcomputer is according to the view data output signal stored in advance.The view data of prior storage is converted according to certain rule according to the display image preset, and this belongs to prior art.
The utility model also relates to a kind of system with aforementioned bike Hot Wheels, and this system also comprises the mobile terminal 2 of the band bluetooth module for image data being sent to bicycle Hot Wheels.The data information memory of picture in terminals such as mobile phones (band bluetooth), can be stored considerable display data message, and can add arbitrarily and change, by Bluetooth transmission, make Hot Wheels 1 can show any picture by us.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
