hop algorithm, to ensure that mobile phone A PP leads to bluetooth The consistent communication module of receiving and sending messages of letter module can be just in communication with each other, and bluetooth communication uses bluetooth hop algorithm and mobile phone APP modules carry out data transmission, and Bluetooth communication hop algorithm are write into mobile phone A PP and bluetooth communication, to ensure mobile phone The consistent communication module of receiving and sending messages of APP and bluetooth communication can be just in communication with each other, and hop algorithm is that frequency band is divided into some Individual frequency hopping channel, in once connecting, radio transceiver constantly jumps to another according to certain code sequence from a channel Individual channel, only receiving-transmitting sides are communicated according to this rule, and other interference sources can not possibly be disturbed according to same rule, There are 10 kinds of frequency hop sequences altogether, be divided into 79 jumps and 23 and jump, 79 jumps and 23 jumps respectively there are 5 kinds, and they are respectively：Call frequency hopping sequence Row, call answering sequence, search sequence, inquiry response sequence and Channel Hopping Sequence, each channel is by a pseudo-random hopping Sequence represents that the frequency hop sequences of each piconet are different, and frequency hopping selection scheme is made up of two parts：A sequence is selected, The sequence is mapped on Hopping frequencies；In the case where choosing sequence, input data, the data of input are divided into two groups, respectively Local clock and current address, under the connection status of mobile phone A PP modules and bluetooth communication, local clock (CLKN) by One compensation equal with master clock (CLK) is modified, specifically, and local clock is the MCU crystalline substances in bluetooth communication Shake the clock signal produced on circuit, master clock refers to clock signal when MCU receives mobile communication, and equal compensation refers to crystalline substance One compensation circuit of the circuit that shakes connection is compensated the distorted signals received, it is ensured that signal stabilization, the frequency hopping in connection status The input data of selection scheme can only use 27 M S B of clock, and under calling and inquiry sub-state, will use clock Whole 28 MSB, inquiry state refer to bluetooth module can at interval of several seconds inquiry once whether connect mobile phone terminal and whether There is new command, call state refers to a kind of instruction of the change of operating handset APP modules control lamp, under call state, locally Clock will be modified to estimate of the called unit to master unit；The input data of current address is constituted by 28, i.e., whole LAP (bluetooth low address part) and UAP's (bluetooth high address part) is low 4, in connection status, and master unit address can be used, Call and calling unit address is then used under sub- state, and when for inquiry sub-state, will use and GIAC (general polling identifications Code) corresponding UAP/LAP, the local clock and current address inputted under above-mentioned several states export after mapping, constitutes one Individual pseudo-random sequence, the mapping process of frequency hopping selection scheme is operated by an add operation, X O R, arranges operation, second addition Computing and register selecting sequence are constituted, and an add operation adds a constant only on the stage, and to 32 modulus, and for Frequency hop sequences are called, an add operation is unnecessary, because it only changes state in this frequency range, in X O R operations, such as Fruit represents the output of an add operation with Z ', then the four of Z ' L S B make the XOR fortune of mould 2 with address bit A22-19 respectively Calculate, output is respectively Z0, Z1, Z2, Z3.Arrangement operation is the core of the algorithm, is included for 79 hop patterns from input 5 to output 5 switching, during which uses the mode of operation that butterfly-unit is controlled by control word, and the mapping relations for inputting and exporting are jumped according to 79 It is divided into 23 jump both of which following two：For 79 hop patterns, it is 64M Hz's that frequency hopping selection scheme, which will select to take gap, 32 frequency hopping bands, and these frequency hoppings are accessed once with random order, then, one 32 different frequency hopping band of selection, and the like, For calling, calling scanning and the sub- state of call answering, same 32 frequency hopping band will be used, the section is selected by address, it is different Unit will have different exhalation frequency ranges；23 hop patterns are that the digit of each module input signal cable and end are deposited with 79 hop patterns Number of storage unit etc. slightly has difference, can be produced using unified hardware circuit or software program and meet both of which requirement Frequency hop sequences, and in same pattern, in order to produce the frequency hop sequences under various states, it is only necessary to receive mobile phone to Bluetooth chip APP input control signal A-F, X, Yl, Y2 takes different values；

Data signal is reduced to analog signal to control PWM control modules by changing by digital analog converter by ladder algorithm Become color and the brightness of the duty cycle adjustment LED of LED, it is first determined the relation of LED chromaticity coordinates and dutycycle, change LED PWM duty cycle is driven, its LED chromaticity coordinate do not change substantially, and luminous flux correspondingly linear change and luminous flux Ratio be equal to the ratio of dutycycle, so for the convenience of call for Votes in engineering, be approximately considered luminous flux and dutycycle into Direct proportion function relation, has with reference to Jim Glassman blend of colors law：

Y_m=D_rY_r+D₆Y₆+D_bY_b* (1)

The span of the luminous flux in triangle RGB is [0, Y in theory_r+Y_g+Y_b], but when using PWM light modulations, Luminous flux is constrained by dutycycle, it is impossible to the span on realization theory, in dimming process, the mixing of different chromaticity coordinates Light, the ratio of its RGB three primary colours is different, and only dutycycle ratio is 1：1：Its duty Bizet of 1 mixed light can reach simultaneously 100%, now the span of luminous flux is 0~Y_r+Y_g+Y_b, the luminous flux span of other mixed lights is then less than this model Enclose, every group of chromaticity coordinate has corresponding highlight flux, from practical significance, PWM dutycycle should meet D_r≤ 1, D_g ≤ 1, D_b≤ 1, Y_mAs object function, (3) formula is carried out to deform and can obtain

The luminous flux of mixed light should meet (4)~(6) formula simultaneously, can by further colorimetry and algebraic manipulation Know, when mixed light LED coordinates are located at close to the region of feux rouges, the largest duty cycle of feux rouges, now the light described by (4) formula is logical Measure span minimum, it is expected that luminous flux only needs to meet (4) formula, remaining luminous flux need to only meet (5), (6) respectively Formula, further, since there is clear and definite functional relation with correlated colour temperature Tcp in the chromaticity coordinate of daylight track, can be according to correlation Colour temperature tries to achieve the chromaticity coordinate of correspondence daylight, then by dutycycle and the functional relation of chromaticity coordinate determined by (3) formula, directly The functional relation of dutycycle and correlated colour temperature is set up, the chromaticity coordinate of daylight track has following relation：

In correlated colour temperature T_cpIn the case of known, the chromaticity coordinate of typical daylight can be calculated by following formula.

As 4000K≤T_cpDuring≤7000K：

As 7000K≤T_cpDuring≤25000K：

Correlated colour temperature and luminous flux are set when using, you can corresponding chromaticity coordinate is calculated by (7), (8) formula, then (3) formula, which is substituted into, with reference to expected luminous flux tries to achieve corresponding dutycycle.

X in formula_m、Y_m、Z_mIt is the tristimulus values for mixing light source M, Y_r、Y_g、Y_bFor the Y values under the full current work of light source R, G, B； C_r=Y_r/y_r、C_g=Y_g/y_g、C_b=Y_b/y_bFor the tristimulus values sum under the full current work of light source R, G, B, marked in CIE-1931 Quasi- colorimeter system moderate stimulation value Y is equal to luminous flux, under PWM light modulations, and dutycycle is the single factor for controlling LED chromaticity coordinates, If desired luminous flux is Y_m, desired chromaticity coordinate is (x, y), dutycycle of the dutycycle as unknown number, then triple channel Can convolution (1), (2) try to achieve：

The span of the luminous flux in triangle RGB is [0, Y in theory_r+Y_g+Y_b], but when using PWM light modulations, light leads to Amount is constrained by dutycycle, it is impossible to the span on realization theory, in dimming process, the mixed light of different chromaticity coordinates, its The ratio of RGB three primary colours is different, and only dutycycle ratio is 1：1：Its duty Bizet of 1 mixed light can reach 100% simultaneously, Now the span of luminous flux is 0~Y_r+Y_g+Y_b, the luminous flux span of other mixed lights is then less than this scope, every group Chromaticity coordinate has corresponding highlight flux, from practical significance, and PWM dutycycle should meet D_r≤ 1, D_g≤ 1, D_b ≤ 1, Y_mAs object function, (3) formula is carried out to deform and can obtain

The luminous flux of mixed light should meet (4)~(6) formula simultaneously, by further colorimetry and algebraic manipulation, when Mixed light LED coordinates be located at close to feux rouges region when, the largest duty cycle of feux rouges, now the luminous flux described by (4) formula take It is worth scope minimum, it is expected that luminous flux only needs to meet (4) formula, remaining luminous flux need to only meet (5), (6) formula respectively i.e. Can, further, since there is clear and definite functional relation with correlated colour temperature Tcp in the chromaticity coordinate of daylight track, can be according to correlated colour temperature The chromaticity coordinate of correspondence daylight is tried to achieve, then by dutycycle and the functional relation of chromaticity coordinate determined by (3) formula, is directly set up The functional relation of dutycycle and correlated colour temperature, the chromaticity coordinate of daylight track has following relation：

As 4000K≤T_cpDuring≤7000K：

As 7000K≤T_cpDuring≤25000K：

Correlated colour temperature and luminous flux are set when using, you can corresponding chromaticity coordinate is calculated by (7), (8) formula, in conjunction with It is expected that luminous flux, which substitutes into (3) formula, tries to achieve corresponding dutycycle.
