Chinese firm delivers self‑developed core casting for world's most powerful onshore wind turbine_我的网站
A |
[ 新鲜技术解读] 尊界S800(参数|询价)在昨天正式上市，除了常规的外观底盘，灯光系统也给我们留下了深刻印象。 
The core castings for the world's most powerful onshore wind turbine in terms of single‑unit capacity have recently been delivered by a Chinese company, marking a technological breakthrough in the large‑megawatt onshore wind power castings, domestic news portal stdaily.com affiliated with Science and Technology Daily reported on Wednesday.
Independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI), the delivered components include the bearing housing and base castings for 15 MW doubly fed onshore wind turbines. The components need to bear the huge gravity, wind loads and alternating loads transmitted from the blades and hub, and transfer the loads to the generator, ensuring steady rotation of the main shaft.
The products passed all customer inspections and assessments in one go and were officially delivery, stdaily.com reported.
Adopting an advanced modular design, the turbine components delivered can support flexible power adjustment ranging from 13 MW to 16 MW, enabling adaptive operation to varying and complex wind conditions across diverse regions, the report said.
The turbine's rotor diameter ranges from 240 meters to 260 meters, and are compatible with tower heights of 135 meters to 190 meters, delivering a maximum swept area of 53,000 square meters, roughly 8 standard football pitchs (105m×68m). This places the unit's overall performance among the world's top-tier.
Such super-large castings place extremely high demand on material properties, casting processes, dimensional accuracy and internal quality. The successful validation and delivery of the products therefore demonstrate the research and development, as well as manufacturing capabilities in super‑large wind power castings, stdaily.com reported.

C | 具体拆解一下华为的大灯组合。以尊界S800为例。整个灯组分成三个照明部分，2个灯是DLP投影大灯还有一个是LED矩阵大灯。
LED大家已经很熟悉了，重点看看DLP大灯。投影大灯本质上跟投影仪是类似的产品。
D | 只不过汽车的投影大灯有更严格的技术、尺寸和稳定性要求。从结构上看，一般由LED光源、DMD芯片、智能控制单元和散热单元组成。其中LED光源的亮度要接近1万流明，远超家用投影仪，这也保证了其能在白天使用，DMD芯片可以简单理解为微型反光镜，每个微型的反光镜都能翻转，通过翻转进行图案的呈现。

下面，是它的一个简化的工作过程： 摄像头和雷达会配合对前方道路进行扫描，如果发现前方有弯道、施工路段或者其他障碍物会立刻告诉大灯控制系统，此时微型反光镜会快速翻转，将光线反射或者进行遮蔽，照射在道路上就呈现出光幕的变化。 问界、享界、尊界等华系车展现的那些炫酷的灯光功能，都是由这两个灯组模块实现。
F | 另外，华为在识别和遮蔽算法上投入了大量精力，自研了灯光照射算法，减少了投影的图像畸变，研发了防抖算法，确保动态的投射稳定性等。除了能自动变换灯光位置去避免对向车炫目，甚至还能对对向的行人头部进行精准扣除，防止远光灯对行人眼部的照射，提升夜间行车安全。

写在最后：用一句话总结：华为大灯本质就是LED模组+投影大灯模组，同时融合了华为驾驶辅助系统的感知能力，让汽车灯光正式由被动变成主动，同时也让汽车可以更好的与外界进行对话，真正实现了从照明工具到交互媒介的技术革命。（图/文 冷晓阳）Current article:http://www.ninyakenhongnian.sbs/kebrx/a9c86a.docx
