Through the embodiment of the invention, the DMX512 light control system can realize the free grouping of the control loads, and each group can be configured into different control modes to match different load types, so that the DMX512 light control system is suitable for home users of smart homes, business clubs or high-grade office places, the application field of the DMX512 light control system is expanded, and the application of the DMX512 light control system is not limited to the use in leisure and entertainment places such as traditional stage performances, wedding banquet celebrations, KTVs, bars and the like.

Referring to fig. 1, an embodiment of a light control method in an embodiment of the present application may include:

and S101, dividing each channel in the DMX512 light control system into a plurality of groups.

The DMX512 light control system may include 512 channels at most, and in this embodiment, the channels may be divided into a plurality of groups, and a channel address is allocated to a group that needs to be used. The specific number of packets can be set according to actual conditions, and 16 packets are generally divided at most. Each group may define a different name that may be displayed on a display screen, preferably an OLED display screen, of the master controller of the DMX512 light control system.

Step S102, control modes of each group are configured respectively.

In the embodiment of the present application, the control mode of each group may be configured as any one of DIM monochrome, CCT, RGB, RGBW, RGBCCT.

Each group is configured with a start-stop channel address field matched with a corresponding control mode, and all channels in the address field are used as corresponding channels controlled by the group.

And step S103, respectively controlling the light of each group according to the control mode of each group.

As shown in fig. 2, step S103 may specifically include the following processes:

and step S1031, aiming at each group, determining the minimum channel number according to the control mode of the group, and determining the control attribute of each channel of the group according to the minimum channel number.

Each packet first acquires a corresponding group number when the corresponding switch (ON/OFF), Scene control (Scene), timer task control (TimeTask), and endless loop task control (CycleTask) are operated. For scene control, simultaneously obtaining a scene number to be operated from the operation; for the timer task, acquiring a corresponding timer task number from the comparison and judgment of date and time; for the infinite loop task, the current loop Step number (Step) is obtained through the operation of the stay time (StayTime) and the fade time (FadeTime).

And acquiring the control mode of the corresponding packet according to the group number, thereby obtaining the minimum channel number used by the control mode of the corresponding packet and also determining the control attribute of each channel in the packet.

For a DIM monochrome, the minimum number of channels is 1, and the channels in the group are designated as output channels corresponding to the monochrome;

for CCT, the minimum number of channels is 2, and the channels in the packet are respectively designated as output channels corresponding to Warm White (WW) and Cool White (CW);

for RGB, the minimum number of channels is 3, and the channels in the group are respectively designated as the output channels corresponding to red (R), green (G) and blue (B);

for RGBW, the minimum number of channels is 4, and the channels in the group are respectively assigned as the output channels corresponding to red (R), green (G), blue (B) and white (W);

for RGBCCT, with a minimum number of channels of 5, the channels within its group are assigned to output channels for red (R), green (G), blue (B), Warm White (WW), and Cool White (CW), respectively.

Step S1032, obtain the target setting value of the group, and calculate the attribute value of each channel of the group according to the target setting value.

Specifically, if the control mode of the packet includes a Correlated Color Temperature (CCT) attribute, a target color temperature value in the target setting values may be verified first, and whether the target color temperature value is within a specified color temperature value range may be determined. The color temperature value range may be expressed as [ MinVal, MaxVal ], where MinVal is a preset warmest color temperature value and MaxVal is a preset coolest color temperature value. The specific values of the MinVal and the MaxVal may be set according to actual conditions, and preferably, the MinVal may be 2700K, the MaxVal may be 7500K, and K represents the unit kelvin. And if the target color temperature value is in the color temperature value range, directly executing the subsequent cold white and warm white separation steps, if the target color temperature value is greater than MaxVal, adjusting the target color temperature value to MaxVal, if the target color temperature value is less than MinVal, adjusting the target color temperature value to MinVal, and after the adjustment is finished, continuing to execute the subsequent cold white and warm white separation steps.

After the color temperature value range is verified, the cold white attribute value and the warm white attribute value can be respectively calculated according to the target color temperature value in the target setting value. The cool white attribute value is an attribute value of a channel corresponding to the cool white attribute in the group, and the warm white attribute value is an attribute value of a channel corresponding to the warm white attribute in the group.

In a specific implementation of the embodiment of the present application, a unit color temperature value may be first calculated according to the warmest color temperature value and the coolest color temperature value.

The calculation formula is shown as follows:

CCTDataMax_Min＝(MaxVal-MinVal)*1000/255

wherein CCTDDataMax _ Min is the unit color temperature value; MaxVal-MinVal is a difference value of the color temperature value range, and the difference value can be enlarged by 1000 times in order to be accurate to 3 bits after a decimal point in a Micro Controller Unit (MCU); for the DMX512 light control system, the channel data type is byte type, namely, the channel data range controlled by the DMX is 0-255 in data view; dividing the difference into 255 equal parts to obtain the color temperature value of how many K each equal part represents, namely the unit color temperature value.

And then, calculating the cool-white attribute value according to the target color temperature value, the warmest color temperature value and the unit color temperature value.

The calculation formula is shown as follows:

CW_Data＝(TgtVal-MinVal)*1000/CCTDataMax_Min

wherein, TgtVal is the target color temperature value, and CW _ Data is the cold white attribute value.

And finally, calculating the warm white attribute value according to the cool white attribute value.

Since the sum of the cool white attribute value and the warm white attribute value is 255 for CCT control of the same load in the DMX512 light control system, the calculation formula is shown as follows:

WW_Data＝255-CW_Data

wherein WW _ Data is the warm white attribute value.

At this point, warm white and cold white attribute values corresponding to the CCT are separated.

For brightness, the attribute values of the channels in the corresponding control mode can be calculated according to the ratio of 0-100% brightness to the attribute values of the brightness 0-255 mode according to the same ratio.

In the DMX512 light control system, in order to save the use resources of the control channel, there is no dedicated brightness attribute channel in the control data communication packet between the master controller and the decoder of the DMX512 light control system, and the size of 0-255 of each channel attribute value represents the brightness of the channel attribute. Therefore, the brightness attribute value set by the user needs to be calculated according to the ratio of the brightness setting value 0-100% to the brightness attribute value 0-255 and according to the same ratio to the attribute value of each channel in the corresponding control mode.

The 0-100% brightness setting value set by the user on the touch panel of the PC end or the master controller is converted into the corresponding brightness attribute value 0-255 on the touch panel of the PC end or the master controller, so the brightness attribute value 0-255 is directly used in the embodiment of the application, and the attribute value of each channel in the corresponding control mode is calculated according to the same proportion. The specific algorithm is as follows:

(a) it is judged whether or not the current luminance attribute value CurrentDimData _255_ Mode and the attribute value inputctrlparametersata to be converted have a value of 0. If both are not 0, executing the conversion of the following steps (b) and (c); otherwise, directly assigning the channel attribute value to be converted to be equal to 0, and skipping the conversion of the following steps (b) and (c).

(b) Calculating a ratio value DimDataScale of the current brightness attribute value CurrentDimData _255_ Mode of the 0-255 Mode and 255:

DimDataScale＝CurrentDimData_255_Mode*10000/255

the result is enlarged by 10000 times in the formula to obtain higher calculation accuracy.

(c) And calculating the attribute values of all channels in the corresponding control modes according to the same proportion.

These channels include red (R), green (G), blue (B), white (W), Warm White (WW), Cool White (CW).

Specifically, the attribute value of each channel may be calculated according to the following formula:

ValidData＝(InputCtrlParameterData*DimDataScale)/10000

the InputCtrlParameterData is the input value of any channel and is set by the user, and the ValidData is the calculated attribute value of the channel.

It should be noted that when ValidData is greater than 0 and less than 2, ValidData is assigned to 2 to reach the minimum value for decoder turn-on.

For example, for the RGB control mode set by the user, the brightness is set to 50%, and the color is set to purple, that is: r is 255, G is 0, and B is 255, then the property values of 50% luminance channel after conversion by the above method are: r-128, G-0, B-128.

And step S1033, respectively filling the attribute values into each channel of the group, outputting in a DMX512 light control data stream mode, and performing light control.

And calculating the head and tail channel addresses of the corresponding groups according to the group numbers, judging the legality of the head and tail addresses and judging whether the total number of the channels in the group is matched with the corresponding control mode, and marking the head channel address bits of all the channels of which the channel addresses in the group are matched with the control mode in an integral multiple relation. And carrying out fault tolerance processing, and marking redundant channels, namely marking the first channel address bit of the redundant channel address after the channel address in the mark group is matched with the control mode to be in an integral multiple relation.

And filling the attribute value of the current corresponding control channel to the corresponding channel position in the DMX512 light control data stream to be output according to the four conditions of marking the channel used by the corresponding packet, the minimum channel number used by the control mode of the corresponding packet, the channel address not greater than the tail address in the group and calculating the attribute value of the corresponding control channel. In the DMX512 light control data stream, the data of the channel which is not related to the corresponding grouping at the time is stored and is not changed.

And marking the status flag that the light of the current group is ON or OFF according to the parameter value of the lamp attribute of the operation, so as to correctly execute the next switching (ON/OFF) action. And when all the groups are subjected to ON/OFF operation, the action execution requirement of firstly closing and then opening can be realized. For example, some packet loads are turned on, and the loads of other packets are turned off, so that the operation of turning on and off all the packet loads first and turning on all the packet loads again in the next operation can be realized.

And feeding back the last operation state information of the current packet load, and sending the information to the touch panel through the serial port, wherein an OLED display screen on the touch panel can display corresponding state information. And meanwhile, the LED backlight corresponding to the touch key correspondingly indicates the on and off states of the load.

In a specific implementation of the embodiment of the application, the main controller of the DMX512 light control system can be arranged on a wall surface, which is convenient for a user to operate. Fig. 3 and 4 are schematic diagrams of two different forms of the master controller, wherein the reference numerals are as follows:
