Description

Technical Field

[0001] The present invention relates to the technical field of lamp chip control, and particularly to a method and device for setting a lamp chip without upgrading a controller. Background Art

[0002] In the floodlighting landscape lighting industry, LED driver chips controlled in parallel by DMX512 are widely used, and certain parameters need to be configured for them through a controller. In response to market demands, the number of parameters to be configured is increasing during the continuous upgrading of the chips, and the data protocols are constantly changing and not downward compatible. The traditional approach is that whenever a new chip is launched, the controller needs to upgrade the program according to its configuration protocol to support the configuration of the chip. The drawback of this approach is that whenever a new chip is launched, R & D personnel need to be invested to upgrade the controller program, and continuously increasing the chip support program will continuously reduce the program storage resources of the device, and it will be impossible to upgrade after reaching a certain level.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] To solve the above problems, please refer to Figure 1 , an embodiment of the present invention provides a method for setting a lamp chip without controller upgrade, including:

[0036] S10. Obtain the parameter writing format feature description from the parameter writing format library according to the type of the lamp chip, and construct a protocol format; the parameter writing format library includes the timing sequence of the lamp chip.

[0037] S11. Obtain the data field description from the parameter writing database according to the type of the lamp chip, and determine the data content; the parameter writing database includes the instruction code, parameter code, and the value range of the parameter code of the lamp chip.

[0038] S12. Construct a lamp chip configuration frame according to the protocol format and the data content.

[0039] S13. The controller sends the lamp chip configuration frame to the lamp chip in a cascaded manner or a parallel manner.

[0040] In S10, the parameter writing format library will be queried according to the type of the lamp chip. The parameter writing format feature description for this lamp chip is obtained from the parameter writing format library. The parameter writing database stores the timing information of the lamp chip. Based on this information, the host computer of the controller can determine how to construct the communication protocol format. Then, in S11, the host computer will query the parameter writing database according to the type of the lamp chip. The parameter writing database contains the instruction code (Command Code), parameter code (Parameter Code), and the valid value range of the parameter code of a specific lamp chip, and then determines the actual data content. After having the information of the protocol format and the data content, the controller can construct the lamp chip configuration frame. The configuration frame contains all the configuration information required by the lamp chip, and these information are organized according to the format determined previously. Finally, the controller sends the configuration frame to the lamp chip in a cascaded or parallel manner. This method enables the system to support new types of lamp chips without modifying the internal program of the controller, improving the scalability and maintenance efficiency of the system.

[0041] The above method splits the parameter configuration protocol of the mainstream LED driver chip into two parts: constructing the protocol format and determining the data content. The instruction packet can be encapsulated in the host computer through the abstracted and parameterized format feature description and data field description, and transmitted to the controller through an SD card or a communication interface. The controller sends the level and data sequence to the lamp chip according to the data field description, and most of the parameter settings of the newly added lamp chips can be realized without updating the running program of the controller.

[0042] The host computer can have an interactive interface to select the lamp chip and its corresponding parameter values, and add new parameters; the host computer can have a set of chip parameter writing databases, and generally need to upgrade the parameter writing database for newly added lamp chips; the host computer can have a set of chip parameter writing format libraries. When adding a new lamp chip, if there is no compatibility in the format library, the parameter writing format library needs to be upgraded. Encapsulate the instruction packet (including the parameter writing format and data content) and transmit it to the control, and the new transmission method needs to be upgraded.

[0043] It should be noted that the write parameter format library is saved in text, with one text file for each format. It is compiled by technicians according to the chip data provided in accordance with the method of constructing the protocol format in S10. The text contains the protocol formats (usually also called timings) for various chip configurations. When a certain chip needs to be configured, first find the corresponding format feature description from the library and pass this description to the controller. The controller constructs the protocol format according to the description content. Generally, multiple chips of one manufacturer share a set of formats, and the manufacturer's protocol is finalized and basically no longer changed. When a new chip is launched and its configuration protocol format is not compatible with the existing formats in the current inventory, an update is required, that is, a new set of format feature descriptions is added.

[0044] The write parameter database is saved in text, with one text file corresponding to one chip. It is compiled by technicians according to the chip data provided in a predefined manner. The text contains the instruction codes, parameter codes, and the value ranges of each parameter code included in various chips, which can be used for the software interface to display the chip parameter options. After the user selects them, data abstraction descriptions are performed in the software background and then passed to the controller. The controller fills the data (including instructions and parameter values) into the corresponding protocol format according to the description content and sends it to the lamp chip. Generally, a set of parameters needs to be independently constructed for one chip. When a new chip is launched, corresponding data content needs to be added to the library.

[0045] The lamp chip configuration frame consists of one or more frames similar to DMX512. The frame format includes:

[0046] Idle level: The bus level when there is no data transmission, generally high level.

[0047] Reset code: Generally a low level for a certain duration, and the duration may vary for different chips.

[0048] Start code: Generally a one-byte serial port data with a fixed value of 0 (1 start bit + 8 data bits + 2 stop bits).

[0049] Instruction code: Used to identify what kind of parameter is written, generally variable multiple-byte serial port data (1 start bit + 8 data bits + 2 stop bits).

[0050] Parameter code: A set of parameter values, generally variable multiple-byte serial port data (1 start bit + 8 data bits + 2 stop bits).

[0051] Exemplarily, please refer to Figure 2 , obtaining the write parameter format feature description from the write parameter format library according to the type of the lamp chip and constructing the protocol format, specifically including:

[0052] If there is a code interval between the instruction code and the parameter code of the lamp chip and they need to be uniformly written by the bus, a first type of single-frame protocol format is constructed as the protocol format; the first type of single-frame protocol format includes a reset code, a start code, an instruction code, and a parameter code, and there are code intervals between the reset code, the start code, the instruction code, and the parameter code.

[0053] When there is a code interval between the instruction code (Command Code) and the parameter code (Parameter Code) of the lamp chip and these codes need to be uniformly written through the bus, the controller needs to construct a first type of single-frame protocol format. The design of this format is to ensure the correctness and consistency of data transmission.

[0054] Among them, the reset code is a signal used to initialize the communication link and ensure that the receiving end is in the receiving state. It marks the start of a frame of data and maintains a certain interval from other codes; the start code follows the reset code and is used to clearly inform the receiving party that a frame of data is about to start. In this protocol, the start code is fixed at 0, which means it always remains unchanged and is convenient for identifying the start of the frame; the instruction code specifies the operation command to be executed by the lamp chip. It is located after the start code and also has a code interval from the start code; the parameter code is the parameter value passed to the lamp chip to adjust its working state. The parameter code follows the instruction code and there is also a code interval between them.

[0055] The code interval refers to the time or space interval between the reset code, the start code, the instruction code, and the parameter code. The existence of these intervals is to ensure that each code is not confused and the receiving end can correctly distinguish each code.

[0056] Because it needs to be uniformly written through the bus, this means that all codes - the reset code, the start code, the instruction code, and the parameter code - must be sent as a whole to ensure that the lamp chip can receive the complete command at one time.

[0057] In this way, the controller can dynamically generate configuration frames suitable for different types of lamp chips without changing its own program, thereby realizing the flexible configuration and management of the lamp chips. This method improves the scalability and maintainability of the system and reduces the workload of frequently updating the controller program due to supporting new chips.

[0058] Exemplarily, please refer to Figure 3 , obtaining the write parameter format feature description from the write parameter format library according to the type of the lamp chip, and constructing the protocol format, specifically including:

[0059] If there is no code interval between the instruction code and the parameter code of the lamp chip and they do not need to be uniformly written by the bus, a second - type single - frame protocol format is constructed as the protocol format; the second - type single - frame protocol format includes a reset code, a start code, and several combined codes. There are code intervals between the reset code, the start code, and the combined codes. The combined code includes adjacent instruction code and parameter code, and one combined code corresponds to one lamp chip.

[0060] When there is no code interval between the instruction code (Command Code) and the parameter code (Parameter Code) of the lamp chip and these codes do not need to be uniformly written through the bus, the controller needs to construct a second - type single - frame protocol format. This format is designed to accommodate lamp chips that can write instruction codes and parameter codes independently.

[0061] In the second - type single - frame protocol format, the reset code is used to initialize the communication link and ensure that the receiving end is in the receiving state. It marks the start of a frame of data and has a certain interval from other codes; the start code follows the reset code immediately and is used to clearly inform the receiving party that a frame of data is about to start. In this protocol, the start code is fixed as 0; the combined code is a unit composed of adjacent instruction code and parameter code. Each combined code corresponds to one lamp chip, which means that each lamp chip can receive its exclusive instructions and parameters through such a combined code.

[0062] Although there is no code interval between the instruction code and the parameter code, there are still code intervals between the reset code, the start code, and the combined codes. These intervals are to ensure the clear definition of each code and prevent data confusion. Since they do not need to be uniformly written through the bus, it means that each lamp chip can receive its instruction code and parameter code independently, that is, each lamp chip can process its own combined code.

[0063] According to the requirements of the lamp chip, the instruction code and the parameter code are combined into a combined code. Each combined code represents the complete information required by one lamp chip.

[0064] When constructing the second - type single - frame protocol format, ensure that there are appropriate code intervals between the reset code, the start code, and each combined code to ensure the accuracy of data transmission. The controller sends the constructed configuration frame to the lamp chip in a cascaded or parallel manner. In the cascaded mode, each lamp chip receives its respective configuration frame in sequence; in the parallel mode, all lamp chips receive the configuration frame simultaneously.

[0065] In the above - mentioned way, the controller can dynamically generate configuration frames suitable for different types of lamp chips without changing its own program, thus realizing the flexible configuration and management of lamp chips. This method improves the scalability and maintainability of the system and reduces the workload of frequently updating the controller program due to supporting new chips.

[0066] Exemplarily, according to the type of the lamp chip, obtain the write parameter format feature description from the write parameter format library and construct the protocol format. Specifically, it includes:

[0067] If the lamp chip requires the combined input of several DMX data frames, construct a multi-frame protocol format; the multi-frame protocol format includes a reset code, a start code, and an instruction code, or the multi-frame protocol format includes a reset code, a start code, and a parameter code; the number of bytes of the instruction code or the parameter code has a lower limit and an upper limit.

[0068] When the lamp chip needs to be configured through the combined input of multiple DMX data frames, the controller needs to construct a multi-frame protocol format. The design of this format is applicable to lamp chips that need to complete the configuration task through a series of consecutive data frames.

[0069] In the multi-frame protocol format, the reset code is used to initialize the communication link and ensure that the receiving end is in the receiving state. It marks the start of a frame of data and maintains a certain interval from other codes; the start code follows the reset code immediately and is used to clearly inform the receiving party that a frame of data is about to start. In this protocol, the start code is fixed at 0; if the lamp chip needs to be guided by an instruction code for operation, the multi-frame protocol format will include an instruction code; if the lamp chip needs to adjust its behavior through a parameter code, the multi-frame protocol format will include a parameter code.

[0070] Exemplarily, please refer to Figure 4 , the following embodiment is a transmission example of sending two groups of multi-frame protocol formats when the multi-frame protocol format corresponding to the lamp chip is 2 fields (set 2 channels / dual color):

[0071] The first frame of the first group: There are 3 channels of data, and the data content is: 0x00, 0x00, 0x00;

[0072] The second frame of the first group: There are 3 channels of data, and the data content is: 0x00, 0x00, 0x00;

[0073] The third frame of the first group: There are 3 channels of data, and the data content is: 0x0E, 0x01, 0x00;

[0074] The fourth frame of the first group: There are 3 channels of data, and the data content is: 0x0D, 0x01, 0x00;

[0075] After each frame is sent, wait for 5 ms before sending the next frame. After the fourth frame of the first group of data is sent, wait for 5 ms, and then send a reset of 100 us.

[0076] After waiting for 1 s, send the following second group of configuration commands:

[0077] The first frame of the second group: There is data in 3 channels, and the data content is: 0x00, 0x00, 0x00;

[0078] The second frame of the second group: There is data in 3 channels, and the data content is: 0x00, 0x00, 0x00;

[0079] The third frame of the second group: There is data in 3 channels, and the data content is: 0x26, 0x01, 0x00;

[0080] The fourth frame of the second group: There is data in 3 channels, and the data content is: 0x25, 0x01, 0x00;

[0081] After each frame is sent, wait for 5 ms before sending the next frame. After the data of the fourth frame in the second group is sent, wait for 5 ms, and then send a reset of 100 us.

[0082] Wait for 2 seconds to complete the 2-field function setting.

[0083] The number of bytes of the instruction code or parameter code has a lower limit and an upper limit. This means that the length of each code has a certain limit and cannot exceed the specified range. The lamp chip needs to complete the configuration through the combination of multiple DMX data frames, which means that a single frame may not be sufficient to convey all the necessary configuration information.

[0084] By constructing a multi-frame protocol format, the controller can dynamically generate configuration frames suitable for different types of lamp chips without changing its own program. This method improves the scalability and maintainability of the system, reduces the workload of frequently updating the controller program due to supporting new chips. In addition, this method also ensures that even in the case where multiple frames are required to complete the configuration, the lamp chips can be effectively managed and configured.

[0085] Exemplarily, when constructing the protocol format, several of the characteristic values such as the number of frame groups, group interval, frame group end idle wait, frame group end reset code, frame type, number of frames, frame interval, frame size, reset code duration, start code, code interval, segment interval, and data type are used to construct the protocol format.

[0086] Suppose it is necessary to construct a multi-frame protocol format to configure a lamp chip, which needs to be completed through two DMX data frames, one of which contains the instruction code and the other contains the parameter code. The following is an example of the construction process:

[0087] Determine the number of frame groups: Suppose two frame groups are required to complete the configuration.

[0088] Set the group interval: The interval between groups is 1 millisecond.

[0089] Set the frame group end idle wait: The end idle wait time is 2 milliseconds.

[0090] Set the frame group end reset code: The reset code is at a low level for a duration of 3 milliseconds.

[0091] Select the frame type: The DMX512 class value is 0, indicating a baud rate of 250K and the data is low-order first.

[0092] Set the number of frames: Each frame group contains 2 frames.

[0093] Set the frame interval: The frame interval is 0.5 milliseconds.

[0094] Set the frame size: The data length of each frame is 16 bytes.

[0095] Set the reset code duration: The reset code duration is 1 millisecond.

[0096] Set the start code: The start code is fixed at 0.

[0097] Set the code interval: The code interval is 0.2 milliseconds.

[0098] Set the segment interval: The segment interval is 0.3 milliseconds.

[0099] Set the data type: The instruction code and the data code are separated (representation value is 0).

[0100] In this way, the controller can construct a flexible and efficient multi-frame protocol format to ensure that the lamp chip can accurately receive the required configuration information and perform corresponding operations based on this information.

[0101] Exemplarily, the number of frame groups is the number of configuration frame groups included in one configuration; the group interval is the interval duration between groups; the frame group end idle includes a code value and time parameters; the frame group end reset code includes a code value and time parameters; the frame type is the DMX512 class value; the number of frames is the number of frames included in each group; the frame interval is the interval duration between frames in the same group; the frame size is a variable value following the data field length or a fixed value of the number of data bytes; the reset code duration is the duration parameter when the reset code maintains a low level; the start code is fixed at 0; the code interval is the idle duration between two different codes; the segment interval is the interval between the instruction code and the parameter code during cascaded code writing; the data type is the representation value of the instruction code and the data code.

[0102] Exemplarily, when the DMX512 class value is 0, it indicates that the baud rate of this frame is 250K, the data is low-order first, including 1 start bit, 8 data bits, and 2 stop bits;

[0103] When the DMX512 class value is 1, it indicates that the baud rate of this frame is 250K, the data is high-order first, including 1 start bit, 8 data bits, and 2 stop bits.

[0104] Exemplarily, when the characterization value is 0, it indicates that the instruction code and the data code are separated; when the characterization value is 1, the instruction code and the data code are combined; when the characterization value is 2, it means that the instruction code and the data code do not need to be distinguished.

[0105] In summary, the construction format can be described by the characteristic values in Table 1.

[0107]

[0108]

[0109] Exemplarily, the determination of the data content specifically includes:

[0110] Determine the data content using several fields among the frame sequence number, instruction code, parameter code, and number of chips according to the description of the write parameter format characteristics;

[0111] The frame sequence number is used to identify the frame to which the instruction code, parameter code, and number of chips belong; the instruction code is a set of instruction codes arranged in sequence, and this field is not used when the data type is 2; the parameter code is a set of parameter codes arranged in sequence, and only this field is filled when the data type is 2; the number of chips is the number of cascaded lamp chips during cascaded write parameter, and it is fixed to 1 during parallel write parameter.

[0112] The data content that needs to be determined includes:

[0113] Frame Sequence Number: Used to identify the frame to which the instruction code, parameter code, and number of chips belong. This is to ensure the uniqueness of each frame in the sequence and help the receiving end correctly parse each frame.

[0114] Command Code: A set of instruction codes arranged in sequence. If the data type is 2 (instruction code and data code do not need to be distinguished), this field is not used.

[0115] Parameter Code: A set of parameter codes arranged in sequence. If the data type is 2, only the parameter code field is used.

[0116] Number of Chips: In the cascaded write mode, the number of chips refers to the total number of cascaded lamp chips; in the parallel write mode, the number of chips is fixed to 1, indicating that all lamp chips receive the same configuration frame simultaneously.

[0117] Through the above steps, the controller can determine the specific data content based on the type of the lamp chip and the description of the writing parameter format characteristics required, so as to construct the correct configuration frame. This method not only improves the flexibility of configuration, but also ensures that the lamp chip can correctly receive the required configuration information.

[0118] In summary, the determination of the data content can be described by the fields shown in Table 2.
