The LED lamp bead is usually provided with a control chip, the on-off condition of the LED lamp bead is controlled through the control chip, and the address code of the LED lamp bead is usually required to be burned through a burner or other burning systems. In the lamp bead array, different LED lamp beads are usually combined in series or in parallel, and the burner itself does not know the physical address of the LED lamp bead, that is, the position of each LED lamp bead. Therefore, the burning of the address code of the LED lamp bead cannot be directly carried out. Generally, before the LED lamp beads are combined into a lamp bead array, the address codes of the LED lamp beads need to be burned one by one. And because the address code of LED lamp pearl is fixed, the LED lamp pearl that the address is No. 1 can't be replaced with the LED lamp pearl that the address is No. 100 usually, brings very inconvenience for follow-up maintenance and after-sales maintenance.

Detailed Description

The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict. The terms "first," "second," "third," and "fourth," and the like, herein do not denote any order or importance, but rather are used to distinguish one element from another.

The LED lamp bead is usually integrated with a control chip, the DI and the DO are respectively used as the signal input and the signal output of the control chip, and the control of the on-off condition of the LED lamp bead is realized through an address code. When the DI input port and the DO input port are used, the control chip of the LED lamp bead can receive the control instruction, process the received control instruction and transmit the processed control instruction to the next LED lamp bead, the controller or the burner and other elements. Under other circumstances, the LED lamp pearl can leave out signal output DO, that is to say the LED lamp pearl only has the DI port, and control command does not select the output after passing through DI port input control chip.

An embodiment of the present invention provides a method for burning an address code of an LED lamp bead, which is applied to an array including a plurality of LED lamp beads, as shown in fig. 1, and includes:

s101: entering a random code mode, and acquiring a randomly generated random code by each LED lamp bead;

s102: the LED lamp bead sends the random code to a burner so as to determine a permanent address code corresponding to the random code and a burning instruction comprising the random code and the permanent address code in the burner;

s103: and entering a burning mode, wherein the LED lamp bead receives the burning command, carries out addressing according to the random code and stores the permanent address code.

It should be noted that the lamp bead array includes a plurality of LED lamp beads, and the plurality of LED lamp beads may be connected in series, in parallel, in series and parallel combination, and in parallel and series combination. The specific combination mode in the lamp bead array is not limited, and the method is suitable for the lamp bead arrays in all possible combination modes in series connection, parallel connection, series-parallel connection and parallel-series connection. Before the method is carried out, the lamp bead array and the burner need to be electrified, and communication connection between the burner and the lamp bead array is established. The burner can be connected with the lamp bead array through the controller, and the burner can also be connected through wireless communication or other modes.

In S101, the LED lamp bead enters the burning mode in various forms, and in one embodiment of the present invention, after the control chip of the LED lamp bead detects that the LED lamp bead is powered on and connected to the burner, the LED lamp bead automatically enters the burning mode. In another embodiment of the invention, the LED lamp bead can enter the random code mode by means of an external control system or a burner, and when the external control system or the burner detects that the LED lamp bead is powered on, an instruction for entering the burning mode is sent to a control chip of the LED lamp bead, so as to control the LED lamp bead to enter the burning mode.

In the embodiment of the invention, the burning mode can refer to a random code mode, each LED lamp bead is internally provided with a random code generation module, and in the random code mode, the random code generation module randomly generates a random code and temporarily stores the random code in the LED lamp bead. In other embodiments of the present invention, the LED lamp bead may obtain a random code from the memory. The burner refers to a device or a system for writing a command of burning a lamp bead address into an LED lamp bead chip, and may be an encoder, a burner device or other control devices with burning functions.

In an embodiment of the invention, the random code is a string of numbers. Preferably, the random code is a string of binary digits. For example, a four-bit random code may be any number between 0000-1111. In the embodiment of the present invention, the number of bits of the random code is not uniquely determined. An initial digit can be preset in the random code, that is, in the burning mode, the random code with one digit is defaulted when the random code is generated by the LED lamp bead for the first time, for example, the random code with 10 digits can be generated by default initially. The actual digit of the random code is related to the number of the LED lamp beads, and when the number of the LED lamp beads in the burnt lamp bead array is large, the digit of the random code can be relatively large.

The random code may be one or more numbers randomly generated by the LED lamp bead, may be a string of binary numbers, or may be a combination of other numbers, letters, or symbols, and may be a code that can represent a temporary address of the LED lamp bead. In the embodiment of the invention, the random code is a basic principle for realizing that the LED lamp beads on the same serial branch or the parallel branch emit light according to specified logic, and can be some information burnt by a pass gate circuit in a control chip of the LED lamp beads, and the information represents the address of the LED lamp beads.

In S102, because the number and positions of the LED lamp beads in the lamp bead array are unknown to the LED lamp beads, the lamp beads cannot transmit data to each other, and when an address is burned, the LED lamp beads need to send the random code to a burner or other controllers to process all the random codes, and then the positions and numbers of the LED lamp beads are determined by the random code identification. Because the random code is generated by the lamp beads, the random code can be considered as the address code of the LED lamp beads, and the address code has the function of enabling a burner to determine the positions of the LED lamp beads and distinguish each LED lamp bead. Because the random codes generated by all the LED lamp beads in the lamp bead array at random are equivalent to the fact that the random codes of the LED lamp beads in the lamp bead array are relatively disordered, the random codes can be used as temporary address codes of the LED lamp beads. When the burner receives the random code sent by the LED lamp bead, the position of the LED lamp bead can be determined, the permanent address code corresponds to the LED lamp bead one by one, at the moment, the burner can determine the permanent address code corresponding to the random code, the permanent address code and the temporary address code are combined in a burning command, and the permanent address code and the temporary address code are packaged and sent to the LED lamp bead.

In S103, because the random code generated by the LED lamp bead is temporarily stored in the LED lamp bead, the LED lamp bead can recognize the permanent address code corresponding to the LED lamp bead through the random code, and the permanent address code is burned into the LED lamp bead. The permanent address code can be determined by the burner according to the actual position of the LED lamp bead in the lamp bead array, and the permanent address code can represent the position sequence of the LED lamp bead in the lamp bead array. The format of the burning command can include: random code + permanent address code. After the LED lamp bead receives the burning command, the permanent address code can be identified through the random code in the lamp bead, and therefore the permanent address code is burnt into the LED lamp bead. In S103, the addressing finger finds the permanent address code according to the random code in the burning command.

In one embodiment of the invention, the burning command is further combined with a command for burning the permanent address code into the lamp bead control chip, and the LED lamp bead automatically burns the permanent address code into the lamp bead after receiving the burning command. For example, the series circuit includes 100 LED beads, the random code of the bead number 1 is 0111101, the 100 permanent address codes can be 0000001-. Certainly, the permanent address code may also be the same as the random code, that is, the random code is directly burned into the LED lamp bead as the permanent address, but this method still performs the conversion between the random code and the permanent address code during the lamp bead control procedure. Here, the LED lamp bead stores the permanent address code means that after receiving the burning command, the LED lamp bead controls burning through a controller of a burner, other external controllers, or a controller of a lamp strip, and burns the permanent address code into the lamp bead, thereby writing the permanent address code into the lamp bead.

When the address codes of the LED lamp beads are burned, the random codes representing the temporary address codes are obtained through the LED lamp beads, then the random codes are sent to the burner, the burner confirms the positions of the lamp beads according to the random codes, the burner packs the permanent address codes and the random codes and sends the packed permanent address codes and random codes to the lamp beads, and the lamp beads are addressed through the random codes so that the permanent address codes are stored in the LED lamp beads. The LED lamp bead array can be burnt after the lamp beads are formed into the lamp bead array, when the LED lamp beads are damaged, any one of the LED lamp beads with the same type can be replaced, the fixed address of the LED lamp bead is not required, and the inconvenience of LED lamp bead maintenance caused by the LED lamp bead with the fixed address is avoided. Meanwhile, the LED lamp beads are prevented from being burned one by one in the burning method of the LED lamp beads, and the working procedures are saved.

In an embodiment of the present invention, the sending the random code to a burner includes: the LED lamp beads determine the on-off condition of the lamp beads representing the random codes according to the random codes; the LED lamp beads operate according to the on-off condition of the lamp beads, so that the burner identifies the on-off condition of the LED lamp beads and converts the on-off condition of the LED lamp beads into the random codes. For example, the random code may be 0101, the on/off condition of the LED lamp bead corresponding to the LED lamp bead is off, and the LED lamp bead only needs to perform the on/off action. When the random code is 1010, the on-off condition of the LED lamp bead corresponding to the LED lamp bead is on-off, and the LED lamp bead only needs to execute the on-off action. Correspondingly, the burner only needs to identify the on-off condition of the LED lamp bead. When the burner recognizes the on-off condition of the LED lamp bead, the on-off condition of the LED lamp bead is converted into a random code, so that the random code is sent. The principle of converting the LED lamp bead on-off condition into the random code is the same as the principle of converting the random code into the LED lamp bead on-off condition. For example, when the recorder recognizes the on-off condition of the on-off LED lamp bead, the on-off condition of the on-off LED lamp bead can be converted into 1010 random codes. The beneficial of setting up like this lies in, utilizes lamp pearl bright circumstances of going out to characterize random code, through changing the form that LED lamp pearl is bright goes out and communicate between the ware of burning, right through burning the ware LED lamp pearl bright going out discernment, rethread burning ware will the lamp pearl bright circumstances of going out turns into random code.

In the embodiment of this embodiment, the duration of turning on and off the LED lamp bead may be set in the LED lamp bead control chip, for example, when the random code is 0101, the LED lamp bead may be set to turn off for 1 second, turn on for 1 second, turn off for 1 second, and turn on for 1 second. For another example, when the random code is 1010, the LED lamp bead may be set to be on for 1 second, off for 1 second, on for 1 second, and off for 1 second.

In an embodiment of the invention, the electrical connection between the lamp bead array and the burner can also be established, the LED lamp beads directly send the random code to the burner in the form of an electrical signal, and the burner converts the electrical signal into the random code after receiving the electrical signal.

In one embodiment of the present invention, the LED lamp bead is a multi-color LED lamp bead, and the sending of the random code to the burner by the LED lamp bead includes: the LED lamp beads determine the gray values of the light emission of the wafers with different colors in the LED lamp beads according to the random codes; the wafers with different colors emit light with corresponding gray values so that the burner can identify the light emitting color of the LED lamp beads and convert the light emitting color into a random code. For example, the random code may be ABC, where a is 11111111, B is 00000000, C is 00000000, the pixel corresponding to the light emission of the red wafer is 11111111, the pixel corresponding to the light emission of the green wafer is 00000000, and the pixel corresponding to the light emission of the blue wafer is 00000000, at this time, the light emission condition of the LED lamp bead is red light, and when the burner recognizes that the LED lamp bead emits red light, the burner converts the red light into the random code of ABC, where a is 11111111, B is 00000000, and C is 00000000. Here, the multicolor LED lamp beads may also be RGBW lamp beads, and the gray scale value of the white LED lamp beads is correspondingly increased in the random code. The LED lamp has the advantages that the random code is represented by the gray value of the luminous color, communication is carried out between the form of changing the luminous color of the multicolor LED lamp bead and the burner, the luminous color of the LED lamp bead is identified by the burner, and the luminous color is converted into the random code by the burner.

The random codes generated by different LED lamp beads may have a phenomenon of duplication, for example, when the number of the LED lamp beads is 10, and the random codes are four-digit binary numbers, the probability of duplication of the random codes generated by different LED lamp beads is 97.4%. For another example, when there are 10 LED lamp beads and the random code is a five-digit binary number, the probability of occurrence of duplicate codes of random codes generated by different LED lamp beads is 80%. For another example, when there are 10 LED lamp beads and the random code is a six-digit binary number, the probability of occurrence of duplicate codes in the random codes generated by different LED lamp beads is 53%. For another example, when there are 10 LED lamp beads and the random code is a seven-bit binary number, the probability of occurrence of duplicate codes of random codes generated by different LED lamp beads is 17%. For another example, when there are 10 LED lamp beads and the random code is an eight-bit binary number, the probability of occurrence of duplicate codes of random codes generated by different LED lamp beads is 9%. For another example, when there are 10 LED lamp beads and the random code is a nine-bit binary number, the probability of occurrence of duplicate codes of random codes generated by different LED lamp beads is 4.4%. Therefore, the probability of occurrence of coincident codes of the random codes generated by different LED lamp beads is inversely proportional to the number of bits of the random codes, that is, the higher the number of bits of the random codes is, the lower the probability of occurrence of coincident codes of the random codes generated by different LED lamp beads is, and when the number of bits of the random codes is large enough, the probability of occurrence of coincident codes of the random codes approaches to 0. The coincident codes mean that the random codes generated by at least two LED lamp beads in the random codes generated by all the LED lamp beads are the same.

As shown in fig. 2, in this embodiment, the method for burning the address code of the LED lamp bead is applied to a lamp bead array including a plurality of LED lamp beads, and includes:

s201: entering a random code mode, and acquiring a randomly generated random code by each LED lamp bead;

s202: sending the random codes to the burner so as to judge the duplication codes of all the random codes in the burner;

s203: when the burner judges that all the random codes are not coincident, the LED lamp bead receives a burning command which is determined by the burner and comprises a permanent address code corresponding to the random codes and the random codes, addresses according to the random codes, and receives a control chip which is used by the burner to burn the permanent address code into the LED lamp bead; and when the burner judges that all the random codes have coincident codes, the LED lamp bead receives a coincident code instruction sent by the burner and regenerates the random codes according to the coincident code instruction. The coincident code instruction refers to an instruction for regenerating a random code sent to the LED lamp bead by the burner.

It should be noted that in S202, the LED lamp bead itself may generate a random code but cannot perform the duplication code determination, and the duplication code determination may be performed in a burner, or may be performed in a controller of the LED lamp bead, or may be performed in a controller of the burner. Here, the controller of the burner belongs to the category of burners, and the determination of duplication code in other controllers can be regarded as the same technical means for the determination of duplication code in the burner. And when the burner judges that all the random codes have coincident codes, the LED lamp bead regenerates the random codes and sends the random codes to the burner again, and the process is repeated until all the random codes do not have coincident codes. If the coincident code judgment is not carried out, when the random code has the condition of coincident code, the permanent address codes of a plurality of LED lamp beads in the lamp bead array are the same. The advantage that sets up like this lies in, and the random code that avoids LED lamp pearl to generate is repeated the code and is leaded to the permanent address code that records also the same in the LED lamp pearl of random code, avoids the luminous condition of repeated code LED lamp pearl the same disorder that makes light effect all the time, avoids light control effect to be less than expectation.

In one embodiment of the invention, after the LED lamp beads receive the duplicate code instruction sent by the burner, all the LED lamp beads regenerate the random code, and all the LED lamp beads send the regenerated random code to the burner again for duplicate code judgment until all the random codes do not have the duplicate code phenomenon. Because the probability of occurrence of repeated codes of random codes generated by different LED lamp beads is lower when the digit of the random codes is higher, and the probability of occurrence of repeated codes of the random codes approaches to 0 when the digit of the random codes is large enough. Here, the random code is not generated for the LED lamp beads with the specific repeated code, and all the LED lamp beads are regenerated to generate the random code. The advantage that sets up like this lies in, and the complexity of coincident code instruction is lower relatively, has reduced LED lamp pearl control chip's handling capacity for burn the operation of record procedure.

In one embodiment of the invention, a random code initially sent by the LED lamp beads can default to one digit, and if all random codes have coincident codes, the burner counts the number of all LED lamp beads; and then, re-determining the digit of the random code according to the number of the LED lamp beads, and sending the re-determined digit of the random code to the LED lamp beads, so that the LED lamp beads can re-generate the random code according to the re-determined digit of the random code. Optionally, the burning method of the address code of the LED lamp bead further includes: and after a coincident code instruction sent by the burner is received, the digits of random codes regenerated by all the LED lamp beads are increased. That is to say, when the LED lamp pearl appears coincident code, because the higher the digit of random code, the probability of coincident code is lower. At this time, the probability that all random codes do not repeat can be increased by increasing the number of bits of the random codes. For example, when there are 10 LED lamp beads and the random code is a five-digit binary number, the probability of occurrence of duplicate codes of random codes generated by different LED lamp beads is 80%. At this time, if the number of bits of the random code is increased to six bits, the probability of occurrence of duplicate codes of the random codes generated by different LED lamp beads is 53%. Of course, the number of bits of the random code can also be directly increased to nine bits, the probability of occurrence of duplicate codes of the random codes generated by different LED lamp beads is 4.4%, and the probability of occurrence of duplicate codes is relatively low at this time. The advantage that sets up like this lies in, avoids the initial two-dimensional code number of generating too high, has increased the handling capacity of system, leads to the system operation slower, through the setting of the random code of progressively increasing, can maximize the number of bits that reduces the random code, and the maximize reduces the RAM volume that the random code occupy.

In one embodiment of the invention, after the LED lamp bead receives the duplicate code command sent by the burner, the LED lamp bead only generating the duplicate code of the random code regenerates the random code, and sends the regenerated random code to the burner, and so on until all the random codes do not have the duplicate code phenomenon. Because all LED lamp pearls are connected in series or in parallel, the instructions received by all LED lamp pearls are the same, but only the first lamp pearl can identify the duplicate code instruction. For example, the random codes generated by the two first lamp beads are 0001100111, at this time, the burner sends a recoding instruction to the LED lamp beads, and the recoding instruction includes: the random code generating method comprises a random code (0001100111) generating a repeated code and a random code regenerating instruction, wherein after receiving the repeated code instruction, all LED lamp beads firstly identify whether the random code generating the repeated code is the random code generated by the LED lamp beads, and when receiving the repeated code instruction, a first lamp bead can identify the random code generating the repeated code, and a second lamp bead regenerates the random code, and sends the regenerated random code to a burner for repeated code judgment, so that the process is circulated until all the random codes do not have the repeated code phenomenon. The LED lamp bead that the benefit that sets up like this lies in, only takes place random code coincident code and regenerates the random code, has reduced the handling capacity of combustor to the random code.

In the embodiment of the invention, different random codes are determined by different LED lamp beads according to different process errors.

In an embodiment of the present invention, a random code generation algorithm may be preset in a control chip or a controller of a lamp bead, where the control chip includes a random code generation module, and after the LED lamp bead is powered on, the random code generation algorithm operates to enable the random code generation module of the lamp bead to generate a random code. It should be noted that each bead in the bead array generates a random code.

In another embodiment of the present invention, a random code generating circuit may be provided, and a random code is generated in the lamp bead by the random code generating circuit. In an embodiment of the present invention, the random code generating circuit includes an inverter oscillator, an oscillation frequency of the inverter oscillator is mainly determined by CMOS process parameters, and the CMOS process parameters may have deviations due to different processes, even if devices manufactured under the same process parameters have slight deviations, if the process processes are different, the deviations become larger, and a number of cycles of the oscillation frequency of the inverter oscillator within a set time is recorded. Of course, in another embodiment of the present invention, the number of times the inverter oscillator oscillates within different set times may be recorded. Here, the lower N bits of the inverter oscillator count value are taken as a random code. The deviation of the manufactured device under the same process parameter may be too small, and optionally, the counting value of the inverter oscillator is amplified by a set multiple, and the low N bits of the amplified counting value are taken and placed as random codes. It should be noted that, the value of N here is related to the preset number of bits of the random code. For example, when the count value of the inverter oscillator in 1 second is 11011101101101000100, the data of the lower eight bits can be taken as the random code, i.e., the random code is 01000100; when the count value of the inverter oscillator in 1 second is 11011011101111100111, the data of the lower nine bits can be taken as the random code, that is, the random code is 111100111. This arrangement is advantageous in that the random code is generated by the random code generating circuit integrated with the inverter oscillator, utilizing subtle differences in the inverter oscillator manufacturing process.

In an embodiment of the present invention, the random code generating circuit includes a temperature sensor, the temperature of the control circuit board of different lamp beads is measured by different temperature sensors, and the lower N bits of the value of the temperature sensor are taken as the random code. Optionally, the value of the temperature sensor is amplified by a set multiple, and the low N bits of the amplified value are taken and placed as random codes.

In an embodiment of the present invention, the random code generating circuit includes a noise generator, and the noise generator randomly generates a noise, records a value of the noise, amplifies the value of the noise by a set multiple, and takes the lower N bits of the amplified value as the random code.

The embodiment of the invention provides a burning device of an address code of an LED lamp bead, which is applied to the LED lamp bead and comprises the following components as shown in figure 7:

the generating unit 11 is configured to obtain a randomly generated random code after entering a random code mode;

a sending unit 12, configured to send the random code to a burner, so as to determine, in the burner, a permanent address code corresponding to the random code and a burning instruction including the random code and the permanent address code;

and the burning unit 13 is used for receiving the burning command, addressing according to the random code and storing the permanent address code.

Optionally, as shown in fig. 8, the sending unit 12 is further configured to send the random code to the burner so as to perform duplication judgment on all the random codes in the burner;

and the receiving unit 14 is configured to receive a duplicate code instruction sent by the burner and reacquire the random code according to the duplicate code instruction when all the random codes have duplicate codes.

Optionally, as shown in fig. 9, the system further includes a conversion unit 15, configured to determine, according to the random code, a lighting and extinguishing condition of the LED lamp bead representing the random code;

and the control unit 16 is used for controlling the LED lamp beads to operate according to the on-off condition of the LED lamp beads so that the burner identifies the on-off condition of the LED lamp beads and converts the on-off condition of the LED lamp beads into the random code.

The burning device for the address codes of the LED lamp beads has the same beneficial effects as the burning method for the address codes of the LED lamp beads, and the details are not repeated herein.

The embodiment of the invention provides a burning method of an address code of an LED lamp bead, which is applied to a burner and comprises the following steps as shown in figure 4:

s401: the burner receives a random code sent by the LED lamp bead;

s402: the burner determines a permanent address code corresponding to the random code and a burning command comprising the random code and the permanent address code;

s403: and the burner sends the burning command to the LED lamp bead so that the LED lamp bead can be addressed according to the random code, and the permanent address code is stored in the LED lamp bead.

Because the number of the LED lamp beads in the lamp bead array and the positions of the LED lamp beads are unknown to the LED lamp beads, in S401, the burner receives the random codes sent by the LED lamp beads, and the positions and the number of the LED lamp beads are determined by recognizing the random codes. As an embodiment of the invention, the LED lamp bead can send the random code in a lighting and extinguishing manner, the burner is provided with a photosensitive element, and the lighting and extinguishing conditions of the LED lamp bead are obtained through the photosensitive element. The burner receives random codes sent by all the LED lamp beads, and the random codes comprise: identifying the on-off condition of the LED lamp bead representing the random code of the LED lamp bead; and the burner converts the on-off condition of the LED lamp bead into the random code. That is to say, the sensitization original paper can't directly acquire the random code that LED lamp pearl generated, but can discern the bright circumstances of going out of LED lamp pearl, and then through the bright circumstances of going out of record LED lamp pearl and with the bright circumstances of going out turns into the random code of LED lamp pearl, is equivalent to the anti-process that LED lamp pearl sent the random code. For example: when the photosensitive element identifies the on-off condition of on-off, converting the on-off condition into a random code 1010; when the photosensitive element recognizes the on-off condition of turning off the light, the on-off condition is converted into the random code 0101. That is, a 1 in the corresponding random code is on and a 0 in the corresponding random code is off. Of course, the specific on/off and the corresponding of the numbers in the random code are not particularly limited. It should be noted that the photosensitive element of the burner may be one or more cameras, and when the photosensitive element is a plurality of cameras, the plurality of cameras may respectively correspond to the positions of the LED lamp beads; in certain cases, the photosensitive element may also be a photosensor. The advantage that sets up like this lies in, utilizes the lamp pearl bright circumstances of going out to characterize random code, and is right through the record ware LED lamp pearl bright the going out discernment, will the lamp pearl bright circumstances of going out turns into random code. Of course, when the LED lamp bead communicates with the burner in a light emitting manner, the burner needs to convert the light emitting color of the LED lamp bead into a random code.

In S402, the burner synthesizes the permanent address code and the random code into the burning command, and after the burner acquires all the random codes, the burner can specify the number of the LED lamp beads and the positions of the LED lamp beads in the lamp bead array, for example: the series circuit comprises 100 LED lamp beads, the burner does not know that 100 LED lamp beads exist, when all the LED lamp beads send the random codes to the burner, the burner determines that the number of the LED lamp beads is 100 according to the number of the random codes, and the burner can respectively burn the permanent address codes into the 100 LED lamp beads in sequence at the moment, so that the LED lamp beads are sorted. The format of the burning command can include: random code + permanent address code. For example, the burning command may be: 1010+0001, 1010 is random code, 0001 is permanent address code. In S140, when the LED lamp bead receives the burning instruction, the LED lamp bead generating the random code 1010 can recognize the burning instruction, and further obtain the permanent address code of 0001, and burn the permanent address code of 0001 into the LED lamp bead.

In S403, since the LED lamp bead temporarily stores the random code, the LED lamp bead can recognize the random code in the burning command, and then obtain the corresponding permanent address code through the random code, and further burn the permanent address code into the control chip of the LED lamp bead.

The advantage that sets up like this lies in, when LED lamp pearl damages, can be according to the position of permanent address code finding LED lamp pearl fast, can pass through in addition can arrange LED lamp pearl address code through permanent address code makes address code clearer on digital logic. When the address codes of the LED lamp beads are burned, the random codes representing the temporary address codes are obtained firstly, then burning instructions comprising the random codes and the permanent address codes are confirmed, and the instructions are sent to the LED lamp beads, so that the LED lamp beads can obtain the permanent address codes through the random codes and burn the permanent address codes into the LED lamp beads. When the LED lamp beads are damaged, any one of the LED lamp beads of the same type can be replaced, the fixed address of the LED lamp bead is not required, and inconvenience in maintenance of the LED lamp bead caused by the LED lamp bead of the fixed address is avoided. Meanwhile, the LED lamp beads are prevented from being burned one by one in the burning method of the LED lamp beads, and the working procedures are saved.

In this embodiment, as shown in fig. 5, the method for burning the address code of the LED lamp bead is applied to a burner, and includes:

s501: the burner receives a random code sent by the LED lamp bead;

s502: the burner judges the duplication codes of all the random codes;

s503: when the random code is not repeated, the burner determines a permanent address code corresponding to the random code and a burning command comprising the random code and the permanent address code;

s504: and the burner sends the burning command to the LED lamp bead so that the LED lamp bead can be addressed according to the random code, and the permanent address code is stored in the LED lamp bead.

In S502, the burner performs duplication judgment on all the random codes: when all the random codes are not repeated, the burner sends a burning command comprising a permanent address code corresponding to the random codes and the random codes to the LED lamp bead so as to burn the permanent address code into the LED lamp bead; and when all the random codes have coincident codes, sending a coincident code instruction to the LED lamp beads to enable the LED lamp beads to regenerate the random codes. For example, the random codes generated by the two first lamp beads are 0001100111, and at the moment, the burner sends a coincident code instruction to the LED lamp beads. It should be noted that, the format of the recoding instruction is not limited, but the recoding instruction must include a random code for generating a recoding and a regenerated random code instruction. For example, the format of the recode instruction may be: 0001100111+ regenerate the random code instruction, here 0001100111 refers to the random code where the coincident code occurs. After the LED lamp bead receives the coincident code instruction, whether the random code with the coincident code is generated is identified, and then a regenerated random code instruction matched with the LED lamp bead is obtained. The advantage that sets up like this lies in, and the random code that avoids LED lamp pearl to generate is repeated the code and is leaded to the permanent address code that records also the same in the LED lamp pearl of random code, avoids the luminous condition of repeated code LED lamp pearl the same disorder that makes light effect all the time, avoids light control effect to be less than expectation.

When the number of the LED lamp beads is large and the number of the random code is low, the probability of repeated codes is relatively large. When the recorder receives the random codes sent by all the LED lamp beads, the recorder needs to judge the repeated codes of all the random codes, and if the repeated codes exist, the LED lamp beads need to regenerate the random codes. It should be noted here that the duplication code determination may be a controller in the burner or a controller that controls the burner and the LED lamp bead. In one embodiment of the invention, after the recorder detects the random code coincident code, the recorder sends a coincident code instruction to all the LED lamp beads to regenerate the random code, and the recorder acquires the random code regenerated by all the LED lamp beads again and judges the coincident code of all the regenerated random codes until all the random codes do not have the coincident code phenomenon.

In another embodiment of the invention, after the burner detects the duplication of the random codes generated by the first lamp beads, the burner sends an duplication instruction to the LED lamp beads, so that the first lamp beads regenerate the random codes after receiving the duplication instruction, the burner acquires the random codes regenerated by all the first lamp beads again, and performs duplication judgment on all the regenerated random codes, and the process is repeated until all the random codes do not have the duplication phenomenon. Because all LED lamp pearls are connected in series or in parallel, the instructions received by all LED lamp pearls are the same, but only the first lamp pearl can identify the duplicate code instruction. For example, the random codes generated by the two first lamp beads are 0001100111, at this time, the burner sends a recoding instruction to the LED lamp beads, and the recoding instruction includes: the random code generating method comprises a random code (0001100111) generating a repeated code and a random code regenerating instruction, wherein after receiving the repeated code instruction, all LED lamp beads firstly identify whether the random code generating the repeated code is the random code generated by the LED lamp beads, and when receiving the repeated code instruction, a first lamp bead can identify the random code generating the repeated code, and a second lamp bead regenerates the random code, and sends the regenerated random code to a burner for repeated code judgment, so that the process is circulated until all the random codes do not have the repeated code phenomenon.

If the generated random codes are concentrated in a certain numerical value area, errors can easily occur in the subsequent burning or identification process. In another embodiment of the invention, when the recorder detects that the random codes are concentrated in the numerical region, a region coincident code instruction is sent, so that the LED lamp beads corresponding to all the random codes in the numerical region are regenerated. For example, the random code includes: 0001100100, 0001100101, 0001100110 and 0001100111, the burner can send 0001100XXX + to regenerate the random code command, and at this time, the LED lamp bead with the first seven bits 0001100 in all the random codes can recognize the repeat code command. The random codes in the numerical value region in the random code comparison set are generated again, so that the random code identification error caused by the random code set is avoided, and the accuracy of subsequent random code identification is improved.

In order to improve the accuracy of the regenerated random codes, specifically, when the random codes are detected to have coincident codes, the random codes with the coincident codes and all unused random codes are obtained, and the random codes with the coincident codes and all unused random codes are sent to the LED lamp beads, so that the LED lamp beads generating the random codes with the coincident codes can regenerate one random code in all the unused random codes and the repeated random codes. That is to say, the duplicate code instruction sent by the burner does not regenerate the first lamp bead in all the random codes that may be generated, but generates the first lamp bead in the random codes that are not used by the LED lamp beads and the random codes in which the duplicate codes occur. The advantage of this arrangement is that the comparison between the regenerated random code and all regenerated codes is avoided, increasing the load of the system; and whether the regenerated random code is duplicated or not can be confirmed by directly comparing the regenerated random code, so that the efficiency is improved.

In another embodiment of the present invention, the random code for generating the duplication code has a plurality of different sets of random codes, for example, as shown in the following table, the random code of two second beads is 11101010010101, the random code of three third beads is 00000000011010, and the random code of two fourth beads is 10010100111111. The recoding instruction needs to include a second recoding instruction: 11101010010101 and regenerate random code instructions; a third recode instruction: 00000000011010 and regenerate random code instructions; a fourth recode instruction: 10010100111111 and regenerate random code instructions. When the LED lamp beads are combined in a parallel manner, a complete coincident code instruction needs to be sent to each LED lamp bead. However, when the LED bulbs are combined in series, it is not necessary to send a complete recoding instruction to each LED bulb. When the LED lamp beads are combined together in a series connection mode, namely the control output of the previous LED lamp bead is connected with the control input of the next LED lamp bead, for example, the second lamp bead, the third lamp bead and the fourth lamp bead are connected in the same circuit in series, at the moment, the recoding instruction sent by the recorder comprises a second recoding instruction, a third recoding instruction and a fourth recoding instruction, because the number of the second lamp beads is only two, after the first second lamp bead recognizes the second recoding instruction, the random code is regenerated and the second recoding instruction corresponding to the second lamp bead in the recoding instruction is deleted, so that the second first lamp bead cannot recognize the recoding instruction again; because there are three third lamp beads, when the first third lamp bead recognizes the third re-code instruction, the random code is regenerated but the third re-code instruction is not deleted, and only when the second third lamp bead recognizes the third re-code instruction, the random code is regenerated and the third re-code instruction is deleted, so that the third lamp bead does not recognize the re-code instruction; similarly, because the number of the fourth lamp beads is only two, after the fourth coincident code instruction is identified by the first fourth lamp bead, the random code is regenerated and the fourth coincident code instruction corresponding to the fourth lamp bead in the coincident code instruction is deleted, so that the second fourth lamp bead can not identify the coincident code instruction any more.

Optionally, in an embodiment of the present invention, a random code initially sent by the LED lamp bead defaults to one bit number, and the method for burning the address code of the LED lamp bead further includes: if all the random codes have coincident codes, the burner counts the number of all the LED lamp beads; and re-determining the digit of the random code according to the number of the LED lamp beads, and sending the re-determined digit of the random code to the LED lamp beads to enable the LED lamp beads to re-generate the random code according to the re-determined digit of the random code. For example, when 10 LED lamp beads exist, because when the random code is a nine-bit binary number, the probability of occurrence of duplicate codes of the random codes generated by different LED lamp beads is 4.4%, at this time, the number of bits of the random code can be set to 10 bits, so that the probability of duplicate codes of the random code is relatively low, and even if there is a specific duplicate code, the overall effect of the lamp bead array is not affected; the random code with reasonable bit number can not occupy larger resource of the system. For another example, when there are 20 LED beads, in this case, in order to reduce the probability of LED bead duplication code, the random code may be 10 bits, and in this case, in order to reduce the probability of random code duplication code, the number of bits of the random code may be set to 20 bits. Here, the burner counts the number of all the LED lamp beads, the number of the LED lamp beads can be sent to the LED lamp beads, and the LED lamp beads determine the number of bits of the random code again according to the number of the LED lamp beads and generate the random code again. Typically, the number of bits of the re-determined random code is greater than the number of bits of the original random code. The advantage that sets up like this lies in, avoids the random code number of initial generation too high, has increased the handling capacity of system, leads to the system operation slower, through the setting of the random code of gradual increase, can maximize the number of bits that reduces the random code, and the maximize reduces the RAM volume that the random code occupy.

The embodiment of the invention provides a burning device of an address code of an LED lamp bead, which is applied to a burner and comprises the following components as shown in figure 11:

the receiving unit 21 is used for receiving the random code sent by the LED lamp bead;

the conversion unit 22 is configured to determine a permanent address code corresponding to the random code and a burning instruction including the random code and the permanent address code;

and the sending unit 23 is configured to send the burning instruction to the LED lamp bead so that the LED lamp bead is addressed according to the random code and stores the permanent address code in the LED lamp bead.

Optionally, the method further comprises: a judging unit 24, configured to perform duplication judgment on all the random codes:

and the sending unit 23 is configured to send a duplicate code instruction to the LED lamp bead to regenerate the random code when all the random codes have duplicate codes.

The embodiment of the invention provides a burning method of an address code of an LED lamp bead, which is applied to an array comprising a plurality of LED lamp beads as shown in figure 3, and comprises the following steps:

s301: entering a random code mode, and acquiring a randomly generated random code by each LED lamp bead;

s402: the LED lamp bead determines a temporary address code according to the random code;

s403: the LED lamp bead sends the temporary address code to a burner so as to determine a permanent address code corresponding to the temporary address code and a burning instruction comprising the temporary address code and the permanent address code in the burner;

s404: and entering a burning mode, wherein the LED lamp bead receives the burning command, carries out addressing according to the temporary address code, and receives the permanent address code and burns the permanent address code into a control chip of the LED lamp bead by the burner.

Here, after each of the LED lamp beads obtains a randomly generated random code, the difference between this embodiment and the steps S101-S103 is that, in the lamp bead, the LED lamp bead determines a temporary address code according to the random code, and then sends the temporary address code to a burner. The temporary address code is used for representing a temporary address of the lamp bead, can be different from the random code, and is converted into the temporary address code representing the address of the lamp bead after being processed by a control chip or a controller of the lamp bead before the random code is sent to the burner; the temporary address code may also be the same as the random code. It should be noted that, in this embodiment, after the random code is converted into the temporary address code, the role of the temporary address code is consistent with the role of the random code sent to the burner in the foregoing embodiment, and therefore, the method in the foregoing embodiment is also applicable to this embodiment on the premise that no contradiction occurs.

In one embodiment of the present invention, after step S402, the method further includes: sending the temporary address codes to the burner so as to judge the duplication codes of all the temporary address codes in the burner; when the burner judges that all the temporary address codes are not coincident, the LED lamp bead receives a burning command which is determined by the burner and comprises a permanent address code corresponding to the temporary address code and the temporary address code, addresses according to the temporary address code, and receives a control chip which is used by the burner to burn the permanent address code into the LED lamp bead; when the burner judges that all the temporary address codes have coincident codes, the LED lamp bead receives a coincident code instruction sent by the burner and regenerates the temporary address codes according to the coincident code instruction. The repeated code instruction refers to an instruction for regenerating the temporary address code, which is sent to the LED lamp bead by the burner.

In one embodiment of the present invention, the sending, by the LED lamp bead, the temporary address code to a burner includes: the LED lamp beads determine the on-off condition of the lamp beads representing the temporary address codes according to the temporary address codes; the LED lamp beads operate according to the lamp bead on-off condition so that the burner can identify the lamp bead on-off condition and convert the LED lamp bead on-off condition into the temporary address code.

In one embodiment of the present invention, the LED lamp bead is a multi-color LED lamp bead, and the sending the temporary address code to the burner by the LED lamp bead includes: the LED lamp beads determine the gray values of the light emitted by the light emitting chips with different colors in the LED lamp beads according to the temporary address codes; the light emitting chips with different colors emit light with corresponding gray values so that the burner can identify the light emitting colors of the LED lamp beads and convert the light emitting colors into temporary address codes.

In one embodiment of the present invention, after the LED lamp bead receives the recoding instruction sent by the burner, all the LED lamp beads obtain the random code again, and cover the previous temporary address code.

In one embodiment of the present invention, after the LED lamp beads receive the duplicate code instruction sent by the burner, all the LED lamp beads that generate duplicate codes acquire the random code again, and cover the previous random code.

When the address codes of the LED lamp beads are burned, a representative random code is obtained through the LED lamp beads, the random code is converted into a temporary address code, the temporary address code is sent to a burner, the burner confirms the positions of the lamp beads according to the temporary address code, the burner packs the permanent address code and the temporary address code and sends the packed permanent address code and the packed temporary address code to the lamp beads, and the lamp beads are addressed according to the temporary address code so as to burn the permanent address code into the LED lamp beads. The LED lamp bead array can be burnt after the lamp beads are formed into the lamp bead array, when the LED lamp beads are damaged, any one of the LED lamp beads with the same type can be replaced, the fixed address of the LED lamp bead is not required, and the inconvenience of LED lamp bead maintenance caused by the LED lamp bead with the fixed address is avoided. Meanwhile, the LED lamp beads are prevented from being burned one by one in the burning method of the LED lamp beads, and the working procedures are saved.

The embodiment of the invention provides a burning device of an address code of an LED lamp bead, which is applied to the LED lamp bead and comprises the following components as shown in figure 10:

a conversion unit 15, configured to determine a temporary address code according to the random code;

a sending unit 12, configured to send the temporary address code to a burner, so as to determine, in the burner, a permanent address code corresponding to the temporary address code and a burning instruction including the temporary address code and the permanent address code;

and the burning unit 13 is used for receiving the burning command, addressing according to the temporary address code and storing the permanent address code.

The foregoing storage medium includes: read-only Memory (ROM), Random Access Memory (RAM), and various other media that can store program codes.

The beneficial effects of the computer readable storage medium arranged on the LED lamp bead are the same as the burning method of the address code of the LED lamp bead, and are not repeated herein.
