第一关：老工厂的隐藏入口 / Level 1: The Hidden Entrance of the Old Factory

八月底的蝉鸣黏在梧桐叶尖，陈明攥着半根没吃完的绿豆冰棒，站在棉纺厂家属院的大铁门前。铁门上的“红光棉纺厂”五个红漆字掉了大半，“光”字下面的“厂”字旁还沾着半片去年贴的春联残渣——爷爷说这厂子开了快四十年，去年刚关停，等着整体改造。他脚边碾碎了一片干透的梧桐叶，脆响混着远处隐约的织布机咔哒声，飘进耳朵里。那是厂区角落里留着的三台老织布机，退休的老师傅们舍不得拆，说那是他们跟着干了半辈子的“老伙计”，每天上午还会开俩小时，给家属院的老人解闷。

*The cicada cries in late August stick to the tips of the plane tree leaves. 14-year-old Chen Ming holds a half-eaten mung bean popsicle, standing in front of the big iron gate of the cotton mill’s residential compound. The five red lacquer characters “Hongguang Cotton Mill” on the iron gate are mostly peeled off. Next to the character “factory” under the character “light”, there is half a piece of leftover Spring Festival couplet pasted last year — Grandpa says the mill has been operating for nearly 40 years, and was shut down last year, waiting for overall renovation. The crisp sound of him crushing a dried plane tree leaf mixes with the faint clacking of looms from the distance, drifting into his ears. Those are the three old looms left in the corner of the mill. The retired masters can’t bear to dismantle them, saying they are “old buddies” they worked with for half their lives. They still turn them on for two hours every morning to entertain the elderly in the residential compound.*

“傻站着干啥？快进来！”穿着洗得发白工装的爷爷从门房里探出头，手里攥着半块擦机油的布，虎口处还有道新鲜的划痕——那是昨天拆旧织布机的时候被铁皮刮的。爷爷是厂里退休的高级机修工，口袋里永远别着螺丝刀和游标卡尺，街坊邻居家的水管坏了、自行车链子掉了，找他准能修好。陈明暑假本来是来帮爷爷整理旧工具的，结果进了厂区才发现，除了那三台响个不停的织布机，整个厂区空得能听见回声：车间的玻璃碎了好几块，墙根底下爬满了去年种的丝瓜藤，地上堆着锈迹斑斑的纱锭和断了的梭子，食堂的窗户上还贴着十年前的工作表，边缘已经黄得发脆。

*“What are you standing there for? Come in quickly!” Grandpa, wearing a faded work uniform, sticks his head out of the gatehouse, holding half a piece of cloth for wiping oil. There is a fresh cut on the back of his hand — it was scraped by iron sheet when he dismantled the old loom yesterday. Grandpa is a retired senior mechanic of the mill, with a screwdriver and vernier caliper always tucked in his pocket. If neighbors have broken water pipes or bike chains, he can definitely fix them. Chen Ming came here this summer vacation to help Grandpa organize old tools, but after entering the mill, he found that except for the three clattering looms, the whole mill is so empty that he can hear echoes: several pieces of glass in the workshop are broken, gourds planted last year climb all over the wall foot, piles of rusty yarn bobbins and broken shuttles are on the ground, and the work schedule from ten years ago is still pasted on the canteen window, with yellow and brittle edges.*

爷爷带着陈明往最里面的老车间走，脚下的水泥地坑坑洼洼的，陈明差点被一块翘起来的铁皮绊倒。老车间是厂里最早的厂房，红砖墙上还留着上世纪80年代写的“安全生产”的标语，只是“产”字的左边已经掉了，只剩个“立”字孤零零地挂在墙上。车间里停着那台最老的1511型织布机——这是中国上世纪60年代自主研发的经典棉纺织设备，曾经占全国织机总量的70%以上，被老工人叫做“纺织战马”，爷爷在这台织布机上修了二十多年的机器，连上面的每一道划痕都记得清楚。

*Grandpa takes Chen Ming to the oldest workshop in the innermost part. The cement ground under their feet is bumpy, and Chen Ming almost trips over a raised piece of iron. The old workshop is the earliest factory building of the mill. The slogan “Safe Production” written in the 1980s is still on the red brick wall, but the left part of the character “production” is missing, leaving only the character “stand” lonely on the wall. In the workshop, there is the oldest Type 1511 Loom — this is a classic cotton textile equipment independently developed in China in the 1960s. It once accounted for more than 70% of the total looms in the country, and is called the “textile warhorse” by old workers. Grandpa has been repairing machines on this loom for more than 20 years, and remembers every scratch on it clearly.*

【核心概念】1511型织布机（Type 1511 Loom）：中国自主研发的第一代自动换梭棉织机，标志着中国棉纺织工业从依赖进口走向自主生产，至今仍在我国中小纺织厂有广泛应用。

*【Core Concept】Type 1511 Loom: The first generation of automatic shuttle-changing cotton loom independently developed in China, marking that China’s cotton textile industry has moved from relying on imports to independent production. It is still widely used in small and medium-sized textile factories in China.*

陈明伸手摸了摸织布机的横梁，木头被磨得光滑发亮，是几十年来工人师傅们用手肘撑出来的痕迹。他忽然注意到横梁的最末端，嵌着一个磨得边缘发毛的二维码，不是后来新贴的，倒像是刻在木头里的，颜色比周围的木头深一圈，像是被什么东西磨了几十年才显出来的。他掏出手机扫了一下——刚才在公交上玩了一路游戏，手机只剩1%的电，他本来以为扫不出来，没想到屏幕突然亮了，跳出来一个蓝白色的界面，中间有个铜色的齿轮在慢慢转，周围飘着细碎的纱线图案，和他平时扫的付款码

没想到屏幕突然亮了，跳出来一个蓝白色的界面，中间有个铜色的齿轮在慢慢转，周围飘着细碎的纱线图案，和他平时扫的付款码、健康码都不一样，没有商家信息，只有一圈细细的、和织布机梭子形状一样的边框。他手机屏幕左上角的红色低电量提示突然灭了，原本只剩1%的电量瞬间跳到了满格，陈明吓得差点把手机扔出去——他上周刚换了屏幕，要是摔坏了，这个暑假就别想玩《我的世界》了。

*Unexpectedly, the screen lit up, showing a blue and white interface. In the middle, a bronze gear was turning slowly, surrounded by fine yarn patterns, which were completely different from the payment codes and health codes he usually scanned. There was no merchant information, only a thin circle of borders shaped like loom shuttles. The red low-battery prompt in the upper left corner of his phone screen suddenly went out, and the remaining 1% battery instantly jumped to full. Chen Ming was so scared that he almost threw his phone away — he just changed the screen last week. If it broke, he would not be able to play Minecraft this summer vacation.*

他下意识地点了一下屏幕中间的齿轮，指尖刚碰到玻璃，就感觉一股凉丝丝的力气拽着他的手腕往屏幕里钻，周围的车间突然开始变形：红砖墙变成了半透明的淡蓝色，上面流动着密密麻麻的、像蚊子腿一样的数字和线条，地上堆的锈纱锭变成了发光的绿色数据块，墙上“安全生产”的标语变成了跳动的安全参数面板，那台1511织布机的木横梁变成了金属质感的数字模型，上面的每一个齿轮、每一根皮带都在发光，横梁上方浮着一行淡金色的字：转速205转/分钟，和他刚才用手肘撑着横梁时感受到的震动频率一模一样。陈明还没反应过来，就觉得脚下一空，整个人掉进了发光的蓝色数据流里，棉絮的味道裹着他，和他小时候在纺织厂车间里跑着玩时闻到的味道一模一样。

*He subconsciously tapped the gear in the middle of the screen. As soon as his fingertip touched the glass, he felt a cold force pulling his wrist into the screen, and the surrounding workshop suddenly began to deform: the red brick wall turned into a translucent light blue, with dense numbers and lines flowing on it like mosquito legs, the piles of rusty yarn bobbins on the ground turned into glowing green data blocks, the slogan “Safe Production” on the wall turned into a jumping safety parameter panel, the wooden beam of the Type 1511 loom turned into a digital model with metallic texture, every gear and belt on it was glowing, and a line of light golden words floated above the beam: rotation speed 205 revolutions per minute, which was exactly the same as the vibration frequency he felt when he supported the beam with his elbow just now. Before Chen Ming could react, he felt his feet empty, and the whole person fell into the glowing blue data flow, wrapped in the smell of cotton fluff, which was exactly the same as the smell he smelled when he ran around in the textile mill workshop as a child.*

等他再睁开眼，已经站在了一个和现实里的老车间一模一样的地方，只是所有的东西都带着一层淡蓝色的光晕。三台老织布机在离他不远的地方咔哒咔哒地转着，不过现在能清楚地看到每一台织布机上面都浮着好几个半透明的面板，跳着转速、温度、断纱次数、当日产量这些数据。陈明伸手摸了摸旁边织布机的梭子，指尖碰到的地方跳出来一行字：“梭子材质：锦纶，使用时长：127天，磨损度：17%”，他吓得赶紧缩回了手——这玩意儿怎么跟长了眼睛似的？

*When he opened his eyes again, he was standing in a place exactly the same as the old workshop in reality, except that everything had a light blue halo. The three old looms were clacking and turning not far from him, but now he could clearly see that there were several translucent panels floating on each loom, jumping with data such as rotation speed, temperature, number of broken yarns, and daily output. Chen Ming reached out and touched the shuttle of the loom next to him. Where his fingertips touched, a line of words jumped out: “Shuttle material: nylon, usage time: 127 days, wear degree: 17%”. He was so scared that he quickly retracted his hand — how did this thing have eyes?*

“别怕，这是数据面板，不会伤到你的。”一个年轻的声音从身后传过来，陈明回头一看，不知道什么时候身边站了个穿蓝白色工装的小哥哥，工装左胸上别着个铜色的齿轮徽章，口袋里露着半截迷你游标卡尺，发梢飘着细碎的白色纱线光点，笑起来眼角的皱纹和爷爷门房里那张年轻时的照片里的人一模一样。“我叫小智，是你的引导员，你可以叫我Xiao Zhi。”他挥了挥手，刚才陈明摸过的梭子上的数据面板就消失了，“这里是工业互联网的虚拟训练场，你可以把它理解为现实工厂的数字孪生空间。”

*“Don’t be afraid, this is a data panel, it won’t hurt you.” A young voice came from behind. Chen Ming looked back and didn’t know when a little brother in a blue and white work uniform was standing next to him. There was a bronze gear badge on the left chest of the work uniform, and a mini vernier caliper was exposed in his pocket. Fine white yarn light spots floated on the tip of his hair. When he smiled, the wrinkles at the corners of his eyes were exactly t
