一种模拟火焰燃烧图象的方法及装置A method and device for simulating a flame burning image

技术领域technical field

本发明涉及一种电子技术模拟火焰图象的方法和相关的装置，它应用于电壁炉、装饰性壁灯、壁画及部分显示屏。The invention relates to a method for simulating flame images in electronic technology and related devices, which are applied to electric fireplaces, decorative wall lamps, murals and some display screens.

背景技术Background technique

随着科学技术的发展和环保要求的日益提高，传统的实物燃烧壁炉已经逐步被清洁、安全、方便和卫生的电壁炉所取代。现代家庭装修也更需要具有动感，富有生命力的装饰物品。而过去模仿燃烧火焰的方法，大多采用普通灯泡有限的光源经过透射、反射、衍射、折射和投射等方法产生，亮度不够，画面呆板且缺少真实火焰燃烧时所应有的各种变化，仿真度不高，外部箱体往往比较厚重，电机噪音大。With the development of science and technology and the increasing requirements of environmental protection, traditional solid burning fireplaces have been gradually replaced by clean, safe, convenient and hygienic electric fireplaces. Modern home decoration also needs more dynamic and vital decorative items. In the past, the methods of simulating burning flames were mostly produced by the limited light source of ordinary light bulbs through transmission, reflection, diffraction, refraction and projection. Not high, the external box is often relatively thick, and the motor noise is loud.

如美国专利号为4890600的模仿火焰燃烧图像的装置(Fireplace burningsimulator unit，January2，1990)，其特征是壳体底部前面设置的灯泡，壳体底部后面设有由电动机带动旋转的反光刷条，反光刷条的前面设有背面使光线散射的成像屏如幕墙玻璃，灯泡发出的光线通过反光刷条的不规则反射，在成像屏上形成了徐徐上升的火焰图像，这种装置产生的图象，由于光线是靠反光刷反射灯泡的光线形成的，所以光线的强度不够，火焰的亮度有限，使火焰不够通红，而且火焰呈现图案化，不够逼真自然。For example, the U.S. Patent No. 4890600 is a device for imitating flame burning images (Fireplace burningsimulator unit, January 2, 1990), which is characterized in that a light bulb is arranged in front of the bottom of the housing, and a reflective brush strip driven by a motor to rotate is provided behind the bottom of the housing to reflect light. The front of the brush bar is equipped with an imaging screen on the back to scatter the light, such as curtain wall glass. The light emitted by the bulb is reflected irregularly by the reflective brush bar, forming a slowly rising flame image on the imaging screen. The image produced by this device, Because the light is formed by reflecting the light of the bulb by the reflective brush, the intensity of the light is not enough, the brightness of the flame is limited, the flame is not bright red enough, and the flame is patterned, which is not realistic and natural enough.

如中国专利号为ZL01113160.8的模仿火焰燃烧图像的装置，其采用闪烁光源进行直接投射的，就是在成像屏如幕墙玻璃后面设置有动态光源，动态光源的内部是灯泡，灯泡外面是由电动机带动旋转的中空的柱状透光罩，透光罩上布满透光孔。灯泡的光通过火焰孔板上透光孔照到成像屏上，从而使成像屏上的光点变成了徐徐上升的火焰。由于光线是直射的，所以光线的强度比较高，火焰的也就比较明亮，具有比较大的进步，但是，依然存在火焰图案不够活泼的问题，而且，采用了电动机带动柱式透光罩旋转结构，所以，体积比较大，厚度不够薄，电动机噪音比较大，需要进一步改进。For example, the Chinese patent No. ZL01113160.8 is a device for imitating flame burning images, which uses a flashing light source for direct projection, that is, a dynamic light source is arranged behind the imaging screen such as curtain wall glass. The inside of the dynamic light source is a light bulb, and the outside of the light bulb is driven by a motor. The hollow cylindrical light-transmitting cover driven to rotate is covered with light-transmitting holes. The light from the bulb shines on the imaging screen through the light hole on the flame orifice plate, so that the light spot on the imaging screen becomes a slowly rising flame. Since the light is direct, the intensity of the light is relatively high, and the flame is relatively bright, which is a relatively large improvement. However, there is still the problem that the flame pattern is not lively enough. Moreover, a motor is used to drive the rotating structure of the column-type light-transmitting cover. , Therefore, the volume is relatively large, the thickness is not thin enough, and the motor noise is relatively large, which needs further improvement.

综合前述，上面几种火焰仿真装置虽然各有千秋，但是有一个共同的缺点，闪烁光源都需要机械部件进行传动或带动，形成光源闪烁，从而造成火焰飘动效果，所以整体机械结构比较大，厚度不够薄，重量相对比较重，特别是电动机使用时间一长，容易产生噪音，对于采用火焰孔板的装置，由于其发光的光源是固定不变的，造成火焰形状的图案化，显得单板，不够活泼生动，不能满足消费者的欣赏火焰的要求。To sum up the above, although the above flame simulation devices have their own advantages and disadvantages, they have a common disadvantage. The flickering light source needs to be driven or driven by mechanical parts to form the light source flickering, resulting in the flame fluttering effect, so the overall mechanical structure is relatively large, and the thickness is not thin enough. , the weight is relatively heavy, especially when the motor is used for a long time, it is easy to generate noise. For the device using the flame orifice, because the light source is fixed, the flame shape is patterned, which appears to be a single board and not lively enough. Vivid, can not satisfy the requirement of appreciating flame of consumer.

另查专利号为200610006411.7的中国专利“火焰模拟装备”公开了一种装置，包括：模拟燃料床；前表面靠近模拟燃料床，后表面位于前表面相对位置的屏幕；和火焰影片放映机，用于把火焰的电影投射在后表面上，以便在前表面显示火焰的电影。屏幕的前表面是部分反射的，以便给出模拟燃料床的反射像，使该反射像至少部分地似乎在前表面显示的火焰电影的后面，其缺陷在于体积大，厚度不够薄，而且有机械噪音。专利号为200610008599.9的中国专利“包括空气过滤器的火焰模拟组件”，它包括一外壳，该外壳包括一顶部面板、两块或多块支撑着顶部面板的侧面板、连接所述侧面板的后面板以及一块或多块基本上相对于后面板设置的前面板，还有，该组件具有一模拟燃料床、设置在模拟燃料床后面的一屏幕以及用于在屏幕上提供火焰图像的火焰图像子组件，该屏幕、外壳和模拟燃料床限定一内部腔室，该组件还包括设置成提供从一个或多个进气孔穿过腔室流向让所述空气离开腔室的一个或多个排气孔的气流的一风扇和一个或多个用来过滤在空气流中的至少一部分空气的空气过滤器。内部腔室除了进气孔和排气孔之外基本上是气密的。其缺陷在于在屏幕与火焰图像子组件之间没有任何光学模糊处理组件，要在屏幕上获得比较逼真的图象，势必需要采用高质量的火焰图像电子组件，造成成本上升，不够经济实用。The Chinese patent "flame simulation equipment" whose patent No. is 200610006411.7 discloses a device, including: a simulated fuel bed; a screen whose front surface is close to the simulated fuel bed, and whose rear surface is located opposite to the front surface; and a flame film projector for A movie of the fire is projected on the back surface to display the movie of the fire on the front surface. The front surface of the screen is partially reflective in order to give a reflected image of the simulated fuel bed, which appears to be at least partially behind the film of flames displayed on the front surface, which has the disadvantages of being bulky, not sufficiently thin, and mechanically noise. The Chinese patent No. 200610008599.9 "Flame Simulator Assembly Including Air Filter" includes a housing comprising a top panel, two or more side panels supporting the top panel, and a rear panel connecting the side panels panel and one or more front panels disposed substantially relative to the rear panel, and the assembly has a simulated fuel bed, a screen disposed behind the simulated fuel bed, and flame image sub-frames for providing flame images on the screen An assembly, the screen, housing, and simulated fuel bed define an interior chamber, the assembly further comprising one or more exhaust ports configured to provide flow from one or more intake ports through the chamber to allow said air to exit the chamber A fan for airflow through the holes and one or more air filters for filtering at least a portion of the air in the airflow. The inner chamber is substantially airtight except for the air intake and exhaust holes. Its defect is that there is no optical blur processing component between the screen and the flame image subassembly. To obtain a more realistic image on the screen, it is necessary to use high-quality flame image electronic components, resulting in increased costs, which is not economical and practical.

目前几乎所有的模拟火焰，大多采用白炽灯作为光源，而白炽灯是一种高耗能的落后产品，许多国家都在限制白炽灯的使用，因此利用高效节能的LED(发光二极管)来模拟火焰燃烧，应用前景广阔。At present, almost all simulated flames mostly use incandescent lamps as light sources, and incandescent lamps are a backward product with high energy consumption. Many countries are restricting the use of incandescent lamps, so high-efficiency and energy-saving LEDs (light-emitting diodes) are used to simulate flames. Combustion has broad application prospects.

具体实施方式Detailed ways

以下结合附图实施例对本发明作进一步详细描述。The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

如图1-2所示意，一种模拟火焰燃烧图象的装置，其包括有：LED播放器微处理器控制电路输出播放编录的火焰燃烧视频图象，通过众多的发光二极管组成的面状成像屏1显示这些火焰燃烧的图象；光学模糊处理层2在成像屏1之前，对图象进行修整、校色和模糊化处理；显示屏3在光学模糊处理层2之前，展示火焰燃烧图象，从而产生火焰燃烧的效果。As shown in Figure 1-2, a device for simulating flame burning images includes: the LED player microprocessor control circuit outputs and plays the recorded flame burning video images, through the surface imaging composed of many light-emitting diodes The screen 1 displays these images of flame burning; the opticalblur processing layer 2 performs trimming, color correction and blurring processing on the images before the imaging screen 1; the display screen 3 displays the flame burning images before the opticalblur processing layer 2 , thus producing the effect of flame burning.

LED播放器具有彩色或黑白图片的存储驱动输出功能；成像屏1是由象素为32X64的LED单元板两个并联组成。成像屏1在上端部位可以呈适当的凹凸扭曲状，与火焰扭曲变形相配合一致。播放器可以存储多种物体燃烧的视频素材，最好是3个左右，我们选定了2种，供用户选择使用；火焰燃烧视频是在一定的长度内循环播放，单元长度一般在2秒以上，播放动画或图片，选用的画面为数幅至数千幅之间；我们将每种视频素材按24帧/秒帧幅分解成黑白火焰图片，采用24帧/秒、18帧/秒、12帧/秒三档回放速度，分别表现的是火焰燃烧的快、中、慢；每种视频素材回放的时间分别为11秒、15秒、20秒左右，当然时间越长越好；成像屏1的亮度可以分为多个等级，以适应于不同的使用环境及用户的爱好，这里也分亮、中、暗3个等级；火焰视频最好是全色彩，这样发光二极管和控制电路均为全色彩的，成本会很高，我们这里将视频转换成带有数级灰度的黑白图片，降低了对硬件的要求，这样发光二极管可以选择或单红、或单白、或单黄、或单蓝，或各色彩的组合，颜色以金黄加红色为宜(蓝色火焰以红黄蓝为佳)，这里我们选择的是单一的红色LED，显示屏3后我们还使用了白色的散光膜2c和偏光膜2b，还安装使用了下面为透明绿色上面为透明白色的拱形渐变补色膜2a，使得火焰下面的图象变为金黄色，上面为渐变红色的效果，更象真实的火焰。音频功能中我们选择播放录制的松木燃烧时发出的噼噼啪啪声，并与松木火焰燃烧图象的速度和节奏一致。炭火灯组5通常为两排以上的高亮度发光二极管组成，数量的多少取决于仿真木炭4的大小和炭火亮度的要求，一般分两组交替闪烁，节奏与显示屏3火焰燃烧的速度相近似，速度也分有与成像屏相同的档位，档位的调节也要和成像屏上的火焰同步，LED的颜色我们采取的也是红色。机器的控制面板我们使用的是附带有电壁炉发热部分控制的手动按键和遥控两种方法。The LED player has the storage drive output function of color or black-and-white pictures; the imaging screen 1 is composed of two LED unit boards with a pixel size of 32X64 connected in parallel. The upper end of the imaging screen 1 can be in a suitable concavo-convex twisted shape, consistent with the twisted deformation of the flame. The player can store a variety of video materials of objects burning, preferably about 3, and we have selected 2 types for users to choose from; the flame burning video is played in a loop within a certain length, and the unit length is generally more than 2 seconds , to play animations or pictures, and the selected pictures range from a few to thousands of pictures; we decompose each video material into black and white flame pictures at 24 frames per second, using 24 frames per second, 18 frames per second, and 12 frames per second There are three playback speeds per second, respectively showing the fast, medium and slow flame burning; the playback time of each video material is about 11 seconds, 15 seconds, and 20 seconds, of course, the longer the better; the imaging screen 1 Brightness can be divided into multiple levels to adapt to different usage environments and user preferences. There are also three levels: bright, medium, and dark; the flame video is preferably full-color, so that the light-emitting diodes and control circuits are full-color Yes, the cost will be very high. Here we convert the video into a black and white picture with several levels of grayscale, which reduces the hardware requirements, so that the light-emitting diode can be selected as single red, or single white, or single yellow, or single blue. Or the combination of various colors, the color is preferably golden and red (the blue flame is preferably red, yellow and blue), here we choose a single red LED, behind the display screen 3 we also usewhite astigmatism film 2c and polarized light Thefilm 2b also installs and uses the arch gradientcomplementary color film 2a whose bottom is transparent green and the top is transparent white, so that the image below the flame becomes golden yellow, and the top is the effect of gradient red, more like a real flame. In the audio function, we choose to play the crackling sound of the recorded pine wood burning, and it is consistent with the speed and rhythm of the pine flame burning image. The charcoalfire lamp group 5 is usually composed of more than two rows of high-brightness light-emitting diodes. The number depends on the size of the simulated charcoal 4 and the brightness of the charcoal fire. Generally, it is divided into two groups and flashes alternately. The rhythm is similar to the burning speed of the flame on the display screen 3. , the speed also has the same gear as the imaging screen, and the adjustment of the gear should also be synchronized with the flame on the imaging screen. The color of the LED is also red. For the control panel of the machine, we use two methods: manual button and remote control with electric fireplace heating part control.

补色膜2a(片、板)、偏光膜2b(片、板)、散光膜2c(片、板)通常为透明的，散光膜(片、板)等通常为半通明的，材质一般或玻璃、或塑料、或纸、或其他透明或半透明或上述材料的复合。整个显示屏3离成像屏1的间距与成像质量关系非常大，通常在20-100毫米之间，总有一点画面质量相对效果好的最佳点，具体在什么位置，取决于像素的多少、LED的亮度大小、膜片的种类和数量等。显示屏的作用就是通过调整各种膜片的组合，确定与成像屏的间距，使得播放的画面质量达到线条流畅、层次丰富、亮度适合的要求。The color-complementingfilm 2a (sheet, plate),polarizing film 2b (sheet, plate), andastigmatism film 2c (sheet, plate) are usually transparent, and the astigmatism film (sheet, plate) is usually translucent, and the material is generally glass, Or plastic, or paper, or other transparent or translucent or a composite of the above materials. The distance between the entire display screen 3 and the imaging screen 1 has a great relationship with the image quality, usually between 20-100 mm, there is always a point where the image quality is relatively good, and the specific position depends on the number of pixels, The brightness of the LED, the type and quantity of the diaphragm, etc. The function of the display screen is to determine the distance from the imaging screen by adjusting the combination of various diaphragms, so that the quality of the displayed picture can meet the requirements of smooth lines, rich layers, and suitable brightness.

具体电路模块图见图2，LED播放器中微处理器将有关火焰燃烧视频图象的LED数据输出连接到成像屏，同时，温度控制接口去连接电壁炉中的温度传感器，而发热体控制接口去连接控制电壁炉中的发热体，控制发热体按照人们需要进行发热，微处理器的炭火灯组接口去连接控制仿真木炭下的炭火灯组进行照明闪烁，当然，微处理器另有接口连接遥控模块和按键模块电路，便于进行遥控控制和按键控制，这些都是传统的电路结构，请参见数字电路和LED显示相关技术。The specific circuit module diagram is shown in Figure 2.
