According to the embodiment of the invention, the DMX512 light control system can realize free grouping of control loads, each group can be configured into different control modes and is matched with different load types, so that the DMX512 light control system can be suitable for home users of intelligent households, business meetings or high-grade office places, the application field of the DMX512 light control system is expanded, and the application fields of leisure entertainment places such as traditional stage shows, wedding celebrations, KTVs, bars and the like are not limited.

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

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

A maximum of 512 channels may be included in the DMX512 light control system, and in this embodiment, these channels may be divided into a number of packets, and channel addresses are allocated to the packets that need to be used. The specific number of packets may be set according to practical situations, and typically a maximum of 16 packets are divided. 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, respectively configuring the control modes of the respective packets.

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

Each packet is configured with a start-stop channel address field that matches the corresponding control pattern, and all channels within the address field serve as corresponding channels for the packet control.

Step S103, respectively performing light control on each group according to the control mode of each group.

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

step S1031, for each packet, determining a minimum number of channels according to a control mode of the packet, and determining control attributes of respective channels of the packet according to the minimum number of channels.

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

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

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

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

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

For RGBCT, the minimum channel number is 5, and the channels in the group are respectively designated as the output channels corresponding to red (R), green (G), blue (B), warm White (WW) and Cold White (CW).

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

Specifically, if the control mode of the group includes a Correlated Color Temperature (CCT) attribute, a target color temperature value in the target setting values may be verified first to determine whether it is within a specified color temperature value range. The range of color temperature values 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 MinVal and MaxVal can be set according to practical situations, preferably, minval=2700k, maxval=7500 k, and k represents the unit kelvin. If the target color temperature value is within the color temperature value range, directly executing the subsequent cold white and warm white separation steps, if the target color temperature value is larger than MaxVal, adjusting the target color temperature value to MaxVal, if the target color temperature value is smaller than MinVal, adjusting the target color temperature value to MinVal, and after the adjustment, continuing executing the subsequent cold white and warm white separation steps.

After the verification of the color temperature value range is completed, 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 cold white attribute value is an attribute value of a channel corresponding to the cold 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 calculated first 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 cctdatamax_min is the unit color temperature value; maxVal-MinVal is the difference of the color temperature value range, which can be expanded 1000 times in order to be able to be accurate to the 3 bits after the decimal point in the micro control unit (Micro Controller Unit, MCU); for the DMX512 light control system, the channel data type is byte, namely, the channel data range of the DMX control is 0-255 from the data; dividing the difference into 255 equal parts, and obtaining the color temperature value of how much K each equal part represents, namely the unit color temperature value.

Then, the cool white attribute value is calculated from 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 cool white attribute value.

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

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

WW_Data＝255-CW_Data

wherein ww_data is the warm white attribute value.

So far, the attribute values of warm white and cold white corresponding to CCT are separated.

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

Because 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, the size of 0-255 of each channel attribute value indicates the brightness of the channel attribute. Therefore, the brightness attribute value set by the user needs to be calculated according to the same proportion according to the proportion of the brightness attribute value 0-255 corresponding to the brightness setting value 0-100 percent.

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

(a) It is determined whether the current luminance attribute value currentdimdata_255_mode and the attribute value inputctrllparameterdata to be converted are in the case of 0. If both are not 0, performing the transition of continuing to perform the following steps (b), (c); otherwise, the channel attribute value to be converted is directly assigned to be equal to 0, and the conversion in the following steps (b) and (c) is skipped.

(b) Calculating the ratio DimDataScale of the current brightness attribute values CurrentDimData_255_Mode and 255 in the 0-255 mode:

DimDataScale＝CurrentDimData_255_Mode*10000/255

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

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

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

The attribute value of each channel can be calculated according to the following formula:

ValidData＝(InputCtrlParameterData*DimDataScale)/10000

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

Note that validdata=2 is assigned when ValidData is greater than 0 and less than 2 to reach the minimum value of decoder on.

For example, in RGB control mode set by the user, the brightness is set to 50% and the color is set to purple, i.e.: r=255, g=0, b=255, then after conversion by the above method, the attribute values of the 50% luminance channel are: r=128, g=0, b=128.

And step S1033, filling the attribute values into each channel of the packet respectively, and outputting the attribute values in a form of DMX512 light control data stream for light control.

And according to the group number, calculating the head and tail channel addresses of the corresponding groups, judging the validity of the head and tail addresses, 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 channels of which the channel addresses in the group are matched with the control mode into an integer multiple relation. And carrying out fault tolerance processing, and marking redundant channels, namely marking the first channel address bit of the redundant channel addresses after the channel addresses in the group are matched with the control modes to be in an integer multiple relation.

And filling the attribute value of the current corresponding control channel into the corresponding channel position in the DMX512 light control data stream to be output according to 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 larger 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 not related to the corresponding packet at this time is stored without changing the original data.

And marking a state mark that the current grouped lights are ON or OFF according to the parameter values of the lamp attributes of the operation so as to correctly execute the next switching (ON/OFF) action. And when ON/OFF operations are performed ON all packets, such an action execution requirement as OFF-before-ON can be fulfilled. For example, some packet loads are on, while other packet loads are off, so that the current operation of switching off all packet loads first and then switching on all packet loads next can be realized.

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

In a specific implementation of the embodiment of the application, the main controller of the DMX512 light control system may be disposed on a wall surface, so that a user can operate the DMX512 light control system conveniently.
