[0002] As the perfect choice for vehicle lighting, ambient lighting allows users to set their favorite scene lighting effects based on their own lighting needs (such as color, temperature, etc.), and select and control the brightness, grayscale, and color changes of light in different spaces and times according to their respective requirements and scene conditions.

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] The core of this application is to provide an atmosphere lamp parameter calibration method, device, medium and equipment.

[0052] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0053] Figure 1 A structural diagram of an atmosphere light parameter calibration device provided in an embodiment of the present application, such as Figure 1 As shown, the device includes: an industrial computer 01, a controller 02, and a scanning device 03.

[0054] The scanning device 03 is used to scan the logo information on each atmosphere lamp 018 to obtain the identity information of each atmosphere lamp 018, and send the obtained identity information to the industrial computer 01. The industrial computer 01 is used to obtain a database containing parameter data of all atmosphere lamps 018, obtain the identity information of each atmosphere lamp 018 sent by the scanning device 03, obtain the parameter data corresponding to each atmosphere lamp 018 from the database according to the identity information of each atmosphere lamp 018, and send the parameter data to the controller 02. The controller 02 is used to adjust the PWM output duty cycle according to the correspondence between the target parameter and the parameter data so that the lighting effect of each atmosphere lamp 018 reaches the target parameter.

[0055] It should be noted that the atmosphere lamp 018 in this application has its corresponding logo information. By scanning the logo information, the identity information of the atmosphere lamp 018 can be obtained, and the parameter data of the atmosphere lamp 018 can be found from the database containing the parameter data of all the atmosphere lamps 018 in the batch through the identity information. The logo information can be in the form of a QR code, a barcode, etc., which can be scanned by a scanning device 03 such as a barcode scanning gun, a barcode scanning box, etc. After obtaining the identity information, the scanning device 03 sends it to the industrial computer 01, and the industrial computer 01 searches for the parameter data of the atmosphere lamp 018 in the database. It can be understood that the database can be input into the industrial computer 01 by a technician in advance, or it can be obtained by the industrial computer 01 from other servers. After finding the parameter data corresponding to the atmosphere lamp 018, the industrial computer 01 sends it to the controller 02, and the controller 02 adjusts the PWM output duty cycle through the corresponding relationship between the target parameter and the parameter data so that the lighting effect of each atmosphere lamp 018 reaches the target parameter. Among them, the target parameters are the effect parameters that the user wants to achieve, which are the color and brightness of the atmosphere light that the user wants. It can be understood that the atmosphere light 018 is composed of three colors: red, green, and blue. The parameter data in this application is the data of the three colors of red, green, and blue. The parameter data in the embodiment of this application refers to the data when the red light, green light, and blue light are 100% lit. The lighting effect refers to the color and brightness effect of the atmosphere light when it is finally presented. In this application, the parameters of the three primary colors are adjusted by adjusting the PWM output duty cycle, so that the atmosphere light 018 can achieve the effect that the user wants.

[0056] For ease of understanding, an atmosphere light parameter calibration device provided by the present application is described in detail below in conjunction with specific scenarios.

[0057] like Figure 1As shown, the atmosphere light parameter calibration device provided in this embodiment, in addition to the above-mentioned equipment, also includes a server 04, a wireless network 06, a network card 05, a CAN card 015, a data line 017, a barcode scanner gun fixing bracket 07, a controller PCB board fixing platform 016 with an atmosphere light, and a controller PCB board 012 with an atmosphere light to be calibrated. Among them, the server 04 is a supplier's server 04, which stores parameter data of all atmosphere lights 018 of the same batch. The controller PCB board 012 with an atmosphere light to be calibrated is installed on the controller PCB board fixing platform 016 with an atmosphere light. The industrial computer 01 uses the network card 05 to connect to the server 04 through the wireless network 06, and can obtain a database of parameter data of the same batch of atmosphere lights 018 from the server 04. The scanning device 03 in this embodiment is a barcode scanner gun, which is arranged on the barcode scanner gun fixing bracket 07. Figure 2 A structural diagram of an atmosphere lamp 018 provided in an embodiment of the present application, such as Figure 2 As shown, the atmosphere light 018 includes a QR code 08 , a red light 09 , a green light 010 , and a blue light 011 . Figure 3 A structural diagram of a controller PCB board with an atmosphere light to be calibrated provided in an embodiment of the present application, such as Figure 3 As shown, the PCB board 012 includes a controller 02, which is an MCU microcontroller, a 3-way PWM drive circuit 013, an atmosphere light 018, and a PCB main board with a positioning hole 014. After the PCB board 012 is fixed in position through the positioning hole 014, the barcode scanner is aimed at the QR code 08 of the atmosphere light 018 for scanning. After the barcode scanner obtains the identity information of the atmosphere light 018, it sends it to the industrial computer 01 through the data line 017. The industrial computer 01 finds the parameter data of the atmosphere light 018 in the database and transmits it to the MCU microcontroller through the CAN card 015. The MCU microcontroller adjusts the output duty cycle of the 3-way PWM drive circuit 013, adjusts the red light 09, green light 010, and blue light 011 of the atmosphere light 018, and finally makes the lighting effect of the atmosphere light 018 reach the target parameter.

[0058] In a specific implementation, when the atmosphere light 018 is in use, the red light 09, the green light 010, and the blue light 011 are not directly exposed to the outside, and are usually protected by a shell. However, the shell will affect the light transmittance of the red light 09, the green light 010, and the blue light 011, which ultimately causes the actual effect of the atmosphere light 018 to be different from the effect expected by setting the parameter data. Therefore, when adjusting the parameter data to the target parameter, the influence of the shell should be considered. In this application, the light transmittance parameters of the shell can be stored in the MCU microcontroller in advance. When adjusting the parameter data, the parameter data is adjusted in combination with the light transmittance parameters to avoid the influence of the shell causing the actual effect of the atmosphere light 018 to be different from the effect of the target parameter.

[0059] The ambient light parameter calibration device provided in the embodiment of the present application includes an industrial computer, a controller, and a scanning device. Among them, the scanning device is used to scan the logo information on each ambient light to obtain the identity information of each ambient light, and send the obtained identity information to the industrial computer. The industrial computer is used to obtain a database containing parameter data of all ambient lights, obtain the identity information of each ambient light sent by the scanning device, obtain the parameter data corresponding to each ambient light from the database according to the identity information of each ambient light, and send the parameter data to the controller. The controller is used to adjust the PWM output duty cycle according to the correspondence between the target parameter and the parameter data so that the lighting effect of each ambient light reaches the target parameter. Compared with the current technology, it is necessary to light up each ambient light separately and detect the color parameters in a dark environment. With the present technical solution, the identity information of each ambient light is obtained by scanning the logo information on each ambient light, and the parameter data of each ambient light is directly obtained in the database according to the identity information. The parameter data can be obtained without lighting up separately, which reduces the complexity of the ambient light parameter calibration process.

[0060] Figure 4 A flow chart of a method for calibrating the parameters of an atmosphere lamp provided in an embodiment of the present application is applied to an industrial computer of the above-mentioned atmosphere lamp parameter calibration device, such as Figure 4 As shown, the method includes:

[0061] S10: Obtain a database containing parameter data of all ambient lights.

[0062] S11: receiving the identity information acquired and sent by the scanning device by scanning the logo information of each atmosphere lamp.

[0063] S12: Acquire parameter data corresponding to each atmosphere lamp from a database according to the identity information of each atmosphere lamp.

[0064] S13: Sending parameter data to the controller so that the controller can adjust the PWM output duty cycle according to the corresponding relationship between the target parameter and the parameter data so that the lighting effect of each atmosphere lamp reaches the target parameter.

[0065] Since the atmosphere light parameter calibration method provided in the embodiment of the present application is applied to the industrial computer of the above-mentioned atmosphere light parameter calibration device, the industrial computer and each device have been described in detail in the above-mentioned embodiment, so they will not be repeated in this embodiment.

[0066] In the method for calibrating the parameters of the atmosphere lamp provided in the embodiment of the present application, a scanning device scans the mark information on each atmosphere lamp to obtain the identity information of each atmosphere lamp, and sends the obtained identity information to an industrial computer. The industrial computer obtains a database containing the parameter data of all the atmosphere lamps, obtains the identity information of each atmosphere lamp sent by the scanning device, obtains the parameter data corresponding to each atmosphere lamp from the database according to the identity information of each atmosphere lamp, and sends the parameter data to the controller. The controller adjusts the PWM output duty cycle according to the correspondence between the target parameter and the parameter data so that the lighting effect of each atmosphere lamp reaches the target parameter. Compared with the current technology, it is necessary to light up each atmosphere lamp separately and detect the color parameters in a dark environment. With the present technical solution, the identity information of each atmosphere lamp is obtained by scanning the mark information on each atmosphere lamp, and the parameter data of each atmosphere lamp is directly obtained in the database according to the identity information. The parameter data can be obtained without lighting up separately, which reduces the complexity of the atmosphere lamp parameter calibration process.

[0067] In a specific implementation, the logo information of the atmosphere light may be in the form of a QR code, a barcode, etc. In this embodiment, obtaining the identity information of each atmosphere light with logo information includes:

[0068] The receiving scanning device obtains and sends the identity information by scanning the QR code of each atmosphere light.

[0069] In the method for calibrating the parameters of an atmosphere light provided in the embodiment of the present application, the identification information of the atmosphere light is a QR code. The scanning device obtains the identity information of the atmosphere light by scanning the QR code and sends it to the industrial computer. There is no need to light up the atmosphere light, thereby reducing the complexity of the atmosphere light calibration.

[0070] Figure 5 A flowchart of another method for calibrating parameters of an atmosphere lamp provided in an embodiment of the present application, which is applied to a controller of the above-mentioned calibrating device for parameters of an atmosphere lamp, includes:

[0071] S20: The receiving industrial computer obtains and sends identity information by scanning the logo information of each atmosphere lamp through the receiving scanning device, and obtains parameter data corresponding to each atmosphere lamp from the database according to the identity information of each atmosphere lamp.

[0072] S21: According to the correspondence between the target parameter and the parameter data, the PWM output duty cycle is adjusted so that the lighting effect of each atmosphere lamp reaches the target parameter.

[0073] Since the atmosphere light parameter calibration method provided in the embodiment of the present application is applied to the controller of the above-mentioned atmosphere light parameter calibration device, the controller and each device have been described in detail in the above-mentioned embodiment, so they will not be repeated in this embodiment.

[0074] In the method for calibrating the parameters of the atmosphere lamp provided in the embodiment of the present application, a scanning device scans the mark information on each atmosphere lamp to obtain the identity information of each atmosphere lamp, and sends the obtained identity information to an industrial computer. The industrial computer obtains a database containing the parameter data of all the atmosphere lamps, obtains the identity information of each atmosphere lamp sent by the scanning device, obtains the parameter data corresponding to each atmosphere lamp from the database according to the identity information of each atmosphere lamp, and sends the parameter data to the controller. The controller adjusts the PWM output duty cycle according to the correspondence between the target parameter and the parameter data so that the lighting effect of each atmosphere lamp reaches the target parameter. Compared with the current technology, it is necessary to light up each atmosphere lamp separately and detect the color parameters in a dark environment. With the present technical solution, the identity information of each atmosphere lamp is obtained by scanning the mark information on each atmosphere lamp, and the parameter data of each atmosphere lamp is directly obtained in the database according to the identity information. The parameter data can be obtained without lighting up separately, which reduces the complexity of the atmosphere lamp parameter calibration process.

[0075] In specific implementations, when the ambient light is in use, the red light, green light, and blue light are not directly exposed to the outside, and are usually protected by a shell. However, the shell will affect the light transmittance of the red light, green light, and blue light, ultimately resulting in the actual effect of the ambient light being different from the effect expected by setting the parameter data. Therefore, when adjusting the parameter data to the target parameters, the influence of the shell should be considered.

[0076] Based on the above embodiment, in this embodiment, before the step of adjusting the PWM output duty cycle, the following steps are further included:

[0077] Recall the pre-stored light transmission parameters;

[0078] Calculate the precise parameter data of each atmosphere light based on the light transmission parameters and parameter data;

[0079] Further, according to the correspondence between the target parameter and the parameter data, adjusting the PWM output duty cycle so that the lighting effect of each atmosphere lamp reaches the target parameter includes:

[0080] According to the correspondence between the target parameters and the precise parameter data, the PWM output duty cycle is adjusted to make the lighting effect of each atmosphere light reach the target parameter.

[0081] In the atmosphere lamp parameter calibration method provided in the embodiment of the present application, the light transmittance parameters of the shell are stored in the controller in advance. When adjusting the parameter data, the precise parameter data of each atmosphere lamp is calculated based on the light transmittance parameters and the parameter data. Then, based on the correspondence between the target parameters and the precise parameter data, the PWM output duty cycle is adjusted to make the lighting effect of each atmosphere lamp reach the target parameter, thereby avoiding the actual effect of the atmosphere lamp being different from the effect of the target parameter due to the influence of the shell.

[0082] It is understandable that, in a specific implementation, the parameter data of the same batch of atmosphere lamps should be substantially the same. During calibration, if the range of adjusting the PWM output duty cycle is too large, there may be an error in the atmosphere lamp batch. Therefore, based on the above embodiment, this embodiment also includes:

[0083] If the PWM output duty cycle is adjusted beyond the preset adjustment range, an alarm signal is issued.

[0084] The ambient light parameter calibration method provided in the embodiment of the present application sends out an alarm signal if the PWM output duty cycle is adjusted beyond a preset adjustment range to prompt the technician to verify whether the ambient light batch does not match the target parameters.

[0085] In addition, the embodiment of the present application also provides a method for adjusting the PWM output duty cycle. Specifically, the parameter data of the atmosphere light includes the following data:

[0086] Red light source parameters p_x1, p_y1, p_Iv1;

[0087] Green light source parameters p_x2, p_y2, p_Iv2;

[0088] Blue light source parameters p_x3, p_y3, p_Iv3;

[0089] Where (p_x1, p_y1), (p_x2, p_y2), (p_x3, p_y3) are the color coordinates of red, green and blue, p_Iv1, p_Iv2, p_Iv3 are the brightness of red, green and blue;

[0090] Transmission parameters include:

[0091] dlt_x1,dlt_y1,coef_Iv1,dlt_x2,dlt_y2,coef_Iv2,dlt_x3,dlt_y3,coef_Iv3

[0092] The prefix dlt indicates color drift, the prefix coef indicates attenuation coefficient, the color drift value is a signed value, and the attenuation coefficient is less than or equal to 100%.

[0093] The light source parameters of the atmosphere light can be calculated from the above parameters:

[0094] Red light source parameters:

[0095] x1=p_x1+dlt_x1, y1=p_y1+dlt_y1, Iv1=p_Iv1*coef_Iv1.

[0096] Green light source parameters:

[0097] x2=p_x2+dlt_x2, y2=p_y2+dlt_y2, Iv2=p_Iv2*coef_Iv2.

[0098] Blue light source parameters:

[0099] x3=p_x3+dlt_x3, y3=p_y3+dlt_y3, Iv3=p_Iv3*coef_Iv3.

[0100] According to Grassmann's law, when the light source parameters are known to be x1, y1, Iv1, x2, y2, Iv2, x3, y3, Iv3, when this light source is 100% lit, the mixed light source color coordinates (x, y) and brightness (Iv) are

[0101] Iv=Iv1+Iv2+Iv3;

[0102]

[0103]

[0104] By mixing different colors and different brightnesses through this light source, the brightness of the three red, green and blue light sources can be adjusted by PWM. Assuming that the PWM duty cycle of the three red, green and blue drivers is D1, D2, and D3, the color coordinates (x, y) and brightness (Iv) of the mixed light source under this PWM duty cycle control parameter are

[0105] Iv=Iv1·D1+Iv2·D2+Iv3·D3;

[0106]

[0107]

[0108] According to the above formula, we can infer

[0109]

[0110]

[0111]

[0112] Therefore, based on the above formula, the PWM drive duty cycle of the three channels of red, green and blue can be calculated according to the parameter data of the ambient light and the target color and brightness.

[0113] In the above embodiments, the method for calibrating the parameters of the atmosphere lamp is described in detail, and the present application also provides an embodiment corresponding to the device for calibrating the parameters of the atmosphere lamp. It should be noted that the present application describes the embodiments of the device part from two perspectives, one is based on the perspective of the functional module, and the other is based on the perspective of the hardware.

[0115] Figure 6 This is a structural diagram of an atmosphere lamp parameter calibration device provided in an embodiment of the present application, which is applied to an industrial computer of the above-mentioned atmosphere lamp parameter calibration device, such as Figure 6 As shown, the device comprises:

[0118] The second acquisition module 12 is used to acquire parameter data corresponding to each atmosphere lamp from the database according to the identity information of each atmosphere lamp;

[0119] The sending module 13 is used to send parameter data to the controller, so that the controller can adjust the PWM output duty cycle according to the corresponding relationship between the target parameter and the parameter data so that the lighting effect of each atmosphere lamp reaches the target parameter.

[0120] In the atmosphere light parameter calibration device provided in the embodiment of the present application, a scanning device scans the mark information on each atmosphere light to obtain the identity information of each atmosphere light, and sends the obtained identity information to an industrial computer.
