Below the utility model is described in further detail: Christmas tree has trunk, trunk segmentation or not segmentation, when trunk has segmental structure, rotation stop device 19 is arranged, when on the trunk branch 12 being arranged, branch 12 layer distributed, every layer of branch 12 quantity equate, and be arranged with rule, arrange a three-color LED chip light source 15 at each branch 12, there is not branch 12 on the trunk and when only having leaf 13 (such as a tree position), leaf 13 by some is divided a plurality of zones adjacent one another are, puts a three-color LED chip light source 15 at this regional lining, and each three-color LED chip light source 15 connects driver module 16, driver module 16 drives chip by one and peripheral circuit consists of, drive unit 16 drives at least one three-color LED chip light source 15, and each three-color LED chip light source 15 arranges a branch of optical fiber 14 nearby, and an end of optical fiber 14 has smooth cross section, the other end is subdivided into the multi beam bondage in leaf or sticks with glue agent and is bonded on the leaf 13, also can naturally disperse on leaf 13.As shown in Figure 6, the Christmas tree of decorating in this way, all optical fiber head ends have formed a full-color array that distributes along the conical surface.Vertically cutting and launch conical surface array open available covering of the fan array represents.As shown in Figure 7, for the convenient calculating that shows data, the covering of the fan array of Fig. 6 can be deformed into the shape of Fig. 7.All driver modules 16 are connected with each other by holding wire and connect with controller 17, and power line, power supply; Controller 17 is responsible for sending the demonstration data of each driver module.Driver module 16 adopts serially concatenated communication mode receive data.The utility model designs the animation that is adapted at playing on the Christmas tree, and on control method, needn't use external memory storage and RAM according to the characteristics of Christmas tree pixel distribution.Only need a slice single-chip microcomputer, in single-chip microcomputer ROM storage basic display data, draw other by sequential operation and show data, on one side and computing on one side send, do not take mcu resource.This control method needs in conjunction with the communication characteristics that drive chip, and the LED serially concatenated communication drivers chip of prior art has different communication protocol, no matter but be which kind of agreement, it has all comprised following two steps:
1. frame data transmission
Serially concatenated chip frame transfer of data basic principle is the same, when data sent, first cascade chip received the data of front and latchs, and gave next chip the data retransmission of back, transmit so successively, finally realize whole send and receives of frame data.This transmission principle can make data receiver that sequencing is arranged by the order of cascade.And the required time of the transmission of finishing frame data is subjected to the impact of data transmission speed and chip cascade number
2. frame data show
Frame data show an independent instruction, in order to allow in the same frame simultaneously output display of all data, the restriction that this instruction is transmitted by data no longer, some chip can be realized simultaneous display, some chips are subject to brush screen speed, such as brush screen time of UCS1903 are: 0.4 X2X cascade number (0.4 is the chip delays time, and unit is μ s), if 1024 cascades are arranged, brush so the screen time and be: 0.4X2X1024=0.8192MS.Although be not synchronous, this speed is very fast, with regard to the startup of not seeing lamp sequencing and scintillation is arranged at all.
According to these two principles, but just can calculate time of the single-chip microcomputer standby time in a certain specific frame frequency that be responsible for to send data:
But single-chip microcomputer standby time=1/ frame frequency-((all data transmission timing pulses express shortest time+pulse of idsplay order transmission timing expresses the shortest time))
The time of utilizing single-chip microcomputer to leave unused, we can carry out the computing of frame data, because cascade chip can be by the sending order temporal data before not receiving idsplay order, if chip is less demanding to the continuity of frame data transmission, so we will the whole computings of whole frame data not good after again transmission, can send out while calculating, but as long as surpass total time of computing single-chip microcomputer standby time, like this, cascade chip has served as the function of RAM, has saved greatly hardware resource.
Such as Fig. 8, Fig. 9 and shown in Figure 10, the utility model embodiment LED driver module chip adopts UCS1903, and this chip pin as shown in Figure 8.Wherein OUTR is that Red among the LED (red) PWM controls output, OUTG is that Green among the LED (green) PWM controls output, OUTB is that Blue among the LED (indigo plant) PWM controls output, DIN is the data inputs, DO is the data outputs, chip adopts the single-wire communication mode, adopts the mode transmitted signal of NRZ.Chip receives the data that the DIN end is made after electrification reset, behind the enough 24bit of reception, the DO port begins forwarding data, provides the input data for next chip.Before transmitting, the DO mouth drags down always.Chip will not receive new data this moment, chip OUTR, OUTG, three PWM delivery outlets of OUTB are according to the 24bit data that receive, send the signal of corresponding different duty, make R, G, B three primary colours that different brightness occur and change, this brightness changes the light that just can be mixed into different colours.If DIN end input signal is the RESET signal, chip send demonstration with the data that receive, chip will receive new data again after this signal ended, after receiving the 24bit data of beginning, by DO mouth forwarding data, chip is not before receiving the RESET code, and OUTR, OUTG, the former output of OUTB pin remain unchanged, after receiving the above low level RESET code of 24 μ s, the 24bit PWM data pulse widths that chip will receive just now outputs on OUTR, OUTG, the OUTB pin.This chip data transmission speed has 400kbs and two kinds of patterns of 800kbs, and in order to improve the data transmission speed, we select the 800kbs pattern, and signal sequence oscillogram at this moment as shown in figure 11.Under this pattern, be equivalent to position needs of every transmission 1.25 μ s, the RESET instruction needs 24 μ s at least, when display refresher rate reaches 30 frames/second, but 1024 chips of cascade, single-chip microcomputer in this Time Controller is used for data fully and sends, have few the time that to leave unused, but, the animation on the Christmas tree does not need so high frame frequency, does not need so multi-cascade chip yet, if we needed for 24 frame/seconds the soonest, maximum 516 cascades, the single-chip microcomputer in the controller just has enough standby time so, according to formula:
But single-chip microcomputer standby time=1/ frame frequency-(all data transmission timing pulses express shortest time+pulse of idsplay order transmission timing expresses the shortest time)
But single-chip microcomputer standby time=1/24X1000000-(1.25X24X516+24)=41666.67-15504=26162.67 μ s=26.16ms
That is to say, we have the time of 26.16 ms to carry out the computing of frame data, and chip does not have strict continuity requirement to the transmission of frame data, we also can send until send frame data on computing limit, limit so, but, if it is above countless according to sending to be interrupted 24 μ s, chip can be used as the RESET code to this interruption, so can not surpass 24 μ s the operation time of adjacent data.
The below shows that with an animation production process of data illustrates this computing and control method:
Three circles as shown in figure 12 represent respectively 3 kinds of different colors, the animation demonstration data of these 3 kinds different color formations are (every kind of color needs 3 bytes to express) as shown in figure 13, form delegation by per 6 pixels, 516 lamps need 86 row, only shown 16 row among the figure, the regularity of other row is the same.If by the continuous also loop play of certain speed, we will see that Christmas tree is rotating just as the conveyor screw of a colour so with this 6 width of cloth picture, these colors are constantly moved to the treetop from the bottom of tree.Realize these patterns and this animation, only need in single-chip microcomputer ROM, to store basic display data as shown in figure 14.These basic display data are carried out calculation combination by the rule of Figure 15, and the animation that just can form Figure 13 shows data.The combination rule of these data blocks is, the interior data block of same frame is by 6,5,4,3,2, the circulation of 1 inverted order, the initial data piece of each frame is by 1,2,3,4,5,6 sequential loop send and control principle by data according to UCS1903, just can draw the flow chart of Figure 16, finish in this way computing and the transmission of data, program is very simple, while and calculating process just sends data calling by the logic sequencing in fact, almost do not use RAM, if adopt the 36M crystal oscillator, adopt the high-speed microprocessor of 1 clock/machine cycle to carry out computing, the data break maximum also only has several microseconds, all are interrupted the cumulative 20MS(that can not surpass specifically will see programming) can work fully, and these data blocks only take the ROM space of 3X6X6=108 byte, if chip has 20KROM to be used for these basic display data storages (program also needs to distribute in addition the ROM space), so such animation can be done more than 100.
Those skilled in the art do not break away from essence of the present utility model and spirit, can there be the various deformation scheme to realize the utility model, the above only is the better feasible embodiment of the utility model, be not so limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
