The country of thistle will be a museum.

Liu Bei, the king of thistle, came in person. With the right country order Xia Fu, will be the order Su Bo, the arsenal order Su Yue, and a group of master craftsmen, please refer to the "water transport armillary image" structure map sent from Luoyang Lingtai.

When Liu Bei first came to Luoyang, he climbed high and overlooked Luoyang City. See many high-rise buildings at night, and the night shines brightly. At that time, he made up his mind to see the "wonders" in Luoyang City one by one. In particular, the famous Imperial Observatory - Lingtai. However, the heavens do not fulfill people's wishes. The years have passed, and so far it has not been fulfilled. So, Liu Bei went to the table. Ask for a diagram of the structure of many heavy weapons hidden in the altar. The Emperor gladly allowed it. The subordinates of the Lingtai stepped up the sorting and sent it to the Ji Kingdom in batches.

In summer, the observatory is called Qingtai, Shang is called Shentai, and Zhou is renamed Lingtai. Luoyang Lingtai, surrounded by walls in the east and west, open two doors in the north and south. The central building in the wall is a square high platform, that is, the spiritual platform. The platform is ten zhang high, and there are two layers of platforms around it, and the platforms are connected by ramps. There are more than 10 halls built in Taiwan. The top of the altar is a place to observe the sky, and there are official houses built around it. The platform is large in scale and has complete functions. Zhang Heng and Zhang Pingzi designed and manufactured the armillary sphere and the wind and earth motion instrument here, and wrote the "Armillary Sphere Annotation" and "Lingxian", etc., immortal works.

Luoyang Lingtai has been used to Wei and Jin until the Northern Wei Dynasty was abandoned.

The armillary sphere has a long history and is not the first of its kind in the Han Dynasty.

Later generations of "Jin Shu Astronomical Chronicles" once elaborated: ""Yu Shu" said: 'In Xuanji Yuheng, Qi Qizheng. "Kao Lingyao" cloud: "The blame of proportion, on behalf of the weather, to make the prescription." The party members are successful and participate in the rules. When the Lord is dim, it is a trip to the stars and jade. Zheng Xuan said that jade is also an armillary sphere. "Spring and Autumn Wenyao Hook" cloud: "Tang Yao is both in place, Xi and Li Armillary. This is the setting of the image, and its origin is far away. It has been passed down from generation to generation, the historian forbids secrets, and scholars do not see it, so it is announced and covered with boiling.

At the beginning of the Han Dynasty (the beginning of Emperor Wu), Hong, Xian Yu Yuren, Geng Shouchang and other personnel were made to test the calendar. Later, when Emperor He, Jia Xuankui was made, and the zodiac was added.

When Emperor Shun, Zhang Heng made a muddy image again, with internal and external regulations, the north and south poles, the yellow equator, the twenty-four qi, the twenty-eight foreign stars and the five latitudes of the sun and the moon, and turned it into the upper room of the palace with leakage, and the stars haunted and corresponded to the sky. Because of its care, it turned the 'Ruilun Pod' at the bottom of the steps, and it rose and fell with the moon, according to the calendar. ”

Other words. The structural diagram of the "water transport armillary image" sent from Luoyang Lingtai is Zhang Pingzi, which is the culmination of the skilled craftsmen of the past dynasties, and the ink door mechanism is added to improve it.

As shown in Fig. The main body of the water transport phenomenon is a large hollow copper ball to represent the celestial sphere. Half of the sphere is hidden under the horizon, and the other half is exposed on the horizon, just like the heavenly dome seen by ordinary people.

The water transport muddy image is powered by the flowing water of the compensating "drip leakage pot", and the isochronism of the "drip leakage pot" is driven by a set of gear transmission devices inside the muddy image, which can automatically demonstrate the periodic motion of celestial bodies.

Zhang Heng's first creation of water transportation is clearly recorded, and it is the world's first astronomical instrument to be propelled by water power. It is also the predecessor of the modern planetarium, which can be called the first astronomical clock in human history. It was not until the 12th century that mechanical timepieces of the same principle were developed in Europe.

Furthermore. The Elephant additionally drives a mechanical calendar called the "Ruilun Pod". With the waxing and waning of the moon, it can demonstrate the passage of date in a synodic month: imitating the characteristics of a strange tree in mythology, the pod, propelled by flowing water, from the beginning of the month, a leaf appears in one day, to the full moon (fifteen) to produce fifteen pieces, and then another one is collected every day, and until the end of the month, the cycle opens and closes.

The pod is a legendary tree. From the first day to the fifteenth day of the month, one pod per day; And from the sixteenth to the end of the month, a pod fell every day. And so on and so forth. From the number of pods, you can tell what day it is. Therefore, it is also known as "calendar pod".

Inspired by this, Zhang Heng created the "Ruilun Pod". Built-in mechanism: on a vertical shaft, install fifteen paddles with cam effect. Make them act on fifteen pods in turn, and rise and fall according to the time they should be.

This Ruilun pod is now placed next to the outer steps of the armillary sphere hall. The drip leakage pot is connected to the upper one, and the armillary sphere is linked with running water.

"Day and night engine", day and night: from the beginning of the month, the pod turns out one pod every day, to the fifteenth day of the fifteenth, and then one more every day, and then decreases until the moon sets.

This sophisticated combination mechanism indicates not only the date, but also the phases of the moon. That is, according to the lunar calendar in the order of the new day, the first quarter, the sun, the second quarter, the obscure day, etc., the cycle opens and closes. Let the historian of Lingtai, just from the Ruilun pod, you can see the accurate calendar.

Understand the mechanical structure on the drawings clearly. Liu Bei couldn't help but be thrilled and extremely shocked.

In a word. Ruilun pod, can be called "day clock". The exact date of the month can be known by simply counting the leaves of the pods.

However, Liu Bei, the king of thistle, was not satisfied with this: "Xia Gong, can you use this picture as a basis to create a 'time pod (clock)'?" ”

"Dare to ask the lord, what is 'time pod'?" Xia Fu asked. Not surprisingly, the lord will have something to gain.

"That's it...... It can accurately indicate the plate of the 12 hours of the day. After thinking about it for a while, Liu Bei drew casually on the drawing board: "The drip pot is consistent with the leakage carving, and it is not enough to be accurate to one moment for twelve hours a day." In a moment, it is subdivided into "minutes" and "seconds". Therefore, on the same 'Ruilun pod', the second pod (second), the minute pod (minute), the quarter pod (quarter hour), and the hour pod (clock) can be displayed. On the muddy image of water transportation, it can only represent the calendar pod of 'day', accurate to 'second'. ”

"He Mang said 'seconds'." Xia Fu nodded happily: "The lord uses 'Hemang' to show the shortness of time. ”

"Yes, yes." Liu Bei secretly said that it was dangerous. Forget your form for a while, and danger comes out of your mouth.

"Dare to ask the lord, what is the solution to 'points'?" Suber asked again.

"Minutes, a quarter of ten points." Liu Bei had a flash of inspiration. Nowadays, a moment is ten minutes. "One moment is divided into tens", which is one minute in the afterlife.

"I see." All the good craftsmen woke up.

"'Minutes', 'seconds', what do you do?" Xia Fu asked again.

Liu Bei had already thought about it: "Then say 'second'." "Minutes and minutes are seconds.

"A minute and a second?" Xia Fu asked.

"Let's see what people can do." Liu Bei did not give an answer. The implication is that according to the existing technical means, how many seconds can be subdivided, how many seconds will be done. It doesn't have to be 60 seconds a minute.

"Wait, take the order." Xia Fu will lead the general to be a good craftsman and try to create a new type of "Ruilun pod".

Saying. Liu was inspired by the "water transport armillary sphere", and the drawing board he drew casually was actually the first "escapement" in history. It is the core mechanism of watches. Of course, even if there is no Liu Bei's hand-painted ghost board, the craftsmen who will make the museum will make it themselves. It's all the same, but it's just a matter of time.

Liu Bei wanted to return to the city at the bridge that passed through the building and made the first "water transport timer" in history. And the importance of accurate timekeeping cannot be overstated.

To be created.

"Ruilun pods, every second is not bad", then it became an allusion and passed on to future generations.
