Professional equipment, clamps, vises, desktop lathes...of course professional watch repair tools are also indispensable. If a model maker sees these things, they will definitely be envious to death: many of them are high-end equipment that cost a lot of money to buy.
In front of the workbench is a large glass window facing the courtyard. The glass is inlaid with an iron square frame, which not only ensures the strength of the glass but also ensures that the window is large enough to provide sufficient light for the entire studio.
As if there is not enough light, there is a large skylight on the roof of the studio, covered with wooden blinds, which can cast enough light without making the sun too hot and dazzling.
The walls of the studio are lined with rows of small drawers and neat shelves like a Chinese medicine shop. A wide variety of tools and accessories are all stored in categories. These are carefully made by joiners specially hired from Guangzhou.
The best wood is all made of mortise and tenon structure without a single nail. The inside and outside are painted with tung oil and then dried thoroughly in the shade. This ensures the absolute safety of tools and components.
In addition to his workbench, there are four well-equipped small workbench, which belong to Zhong Xiaoying and his apprentices.
Dr. Zhong spends most of his day in the studio. On the side of the workbench is a large, well-equipped drawing board. In the old days, he no longer used the drawing board - he only used CAD, but he left it behind when he was studying.
The foundation is still there, so he can draw fairly easily. All verification equipment is drawn first and then manufactured. The reason for being so meticulous is not only the inertia of his work, but also the use of it to educate his adopted daughter and apprentices.
The purpose is there - there are many elders who can use CAD, but there are very few who have used drawing tablets to make drawings.
Dr. Zhong turned on his work desk lamp and began to make his "complete intellectual property rights" calibrating device. All components of this calibrating device are currently produced by Lingao Industry or will be produced in the near future.
The amplifier used in this "completely independent knowledge copyright" calibration device is a vacuum tube - Lingao's industrial system cannot yet produce such a thing. Dr. Zhong's vacuum tube was obtained from the warehouse of the Planning Institute: Wu De is very
He was solemnly told to use it carefully because there were not many electron tubes in the reserve.
As for the traditional paper tape on the calibration device, he used a frosted glass roller instead of paper, and sprinkled water on the frosted glass roller. For this purpose, he went to Xiao Bailang to order a batch of high-precision frosted glass.
The roller is a thing with a very simple principle. It is not easy to assemble. Dr. Zhong is not a senior fitter, and his level of repair and grinding is quite amateur. The loss is very large, so a lot of spare parts must be prepared during trial production.
While Zhong Xiaoying was working, she quietly started sharpening tools on her workbench. As a watch technician, although there is a full set of ready-made tools available for purchase, she still needs to sharpen them herself. She knows how to sharpen tweezers, screwdrivers and other basic tools.
Tools are the basic skills of a watch technician.
The tweezers should be trimmed to be flat and sharp so that when clamping parts, they will not easily cause parts to fly around or damage the parts, causing scratches on the substrate and other parts.
The diameter of the screwdriver tip of each watch movement is different. The diameter must be trimmed to avoid damaging the screw. The thickness of the screwdriver depends on the different screws. Grind it until the screw and the screwdriver can fit tightly, and insert it to the bottom of the screwdriver tip. That's what meets the requirements.
Zhong Xiaoying is quite accomplished in this matter, so now she does all the sharpening of Dr. Zhong's tools.
"You should go to bed first, it's already very late." Zhong Lizhi said with his back turned, "I still have a full day of work tomorrow."
"My father doesn't have a rest, how can my daughter dare to rest? My daughter is not tired. It's good to do some small things for my father."
Zhong Lishi smiled silently: "Okay, come with me to the observatory later."
This was not a whim. Dr. Zhong’s idea had been submitted for some time. In order to facilitate the work, he needed to let his adopted daughter have access to the core equipment of the Senate. For this reason, he specially submitted an application, and then there was a long wait - ―It was not until a few days ago that he received the written document approving the application.
Zhong Xiaoying's face turned red with excitement - the observatory has always been their "forbidden area", and she knew that no naturalized citizen except the elders could set foot inside.
Her father trusted her so much that he obviously regarded her as his real daughter. A wave of enthusiasm surged in Zhong Xiaoying's chest. She put down her tools, walked to Zhong Lishi, knelt down with a bang, and kowtowed three times: " Thank you very much, Father!"
Dr. Zhong was startled and almost dropped all the tools in his hand. Although it was very sudden, he felt warm in his heart. Then he said gently: "Get up, we don't have to be so polite between father and daughter."
As he was talking, the electronic timer on the table chimed. It was already 23:45. He had to go to the observatory to check the time before 0 o'clock. Dr. Zhong stood up and put a wooden box on the table into his pocket. .
Zhong Xiaoying has already brought her windbreaker. There is a long corridor connecting the studio to the observatory, but it is not completely enclosed. When it is windy and rainy, it is inevitable that the wind and rain will hit you.
Dr. Zhong put it on silently and said, "You should also put on your coat. It's windy outside."
"Yes, thank you for your concern, Father." Zhong Xiaoying also put on a windbreaker and took a lantern to light up the front - there was no lighting in the corridor.
It was windy and rainy outside, dark and cold. The two walked through the corridor in the dark and came to the observatory. The observatory is a three-story red brick building. The "First Meridian of the Yuan Dynasty" is inlaid in bronze on the brick square outside the main entrance. ―Actually, it is the 110th east longitude passing through here.
The corridor leads to the back door of the observatory. Dr. Zhong took out a bunch of keys that he carried with him, took out a key by hand, and opened the steel security door.
The bottom of the observatory is a space with a ceiling that reaches directly to the third floor. The second floor is the Zouma Tower. You can go directly to the roof of the third floor through the circular staircase. The simple observation platform on the roof can be opened manually. The observation platform is equipped with the hand of the Senate. The best astronomical telescope - of course, according to the standards of astronomy, it is amateur level, but according to the standards of this time and space, it is an "artifact".
Dr. Zhong rarely plays with that artifact. What he usually pays attention to is the celestial instrument installed accurately on the 110th line of east longitude. The celestial instrument accurately determines stars by observing the stars passing through the midheaven (passing the meridian circle of the observatory).
The time of passing the midheaven is used to obtain the clock error of the sidereal clock, thereby determining the universal time, the right ascension of the sidereal star and the longitude of the basic astronomical point.
This object was invented in the 17th century, but at this time, Lingao's mid-plane is the only one in the world. Not to mention that it was made in the time and space of the 21st century.
An important purpose of astronomy in ancient society was timing. Using a celestial instrument as a time measurement/determination of longitude and latitude is a mature method. Under the conditions of manual observation at the observatory, second-level accuracy can also be achieved.
The Ministry of Science and Technology has complete longitude and latitude data, coupled with astronomical software, it can make an accurate star table. Coupled with the observation of the rising and setting times of the sun, it can provide timing accurate to the second level. Even in the 21st century, there are accurate
Atomic time, but it still needs to be checked with astronomical time.
Dr. Zhong has so far done all this work himself. Astronomical observation is a very boring and time-consuming thing, and he cannot spend time on it all day long. Otherwise, he would have nothing to do - he still has a radio
The project needs to be conquered.
Xiaoying is a very careful girl and very "sit-down". He plans to slowly train her to do astronomical observations and teach her the principles of timing, rather than becoming a watch technician.
But today he didn't take her to the roof - it was stormy outside, and it was impossible to observe the sky with a mid-plane. He turned on the light, and the light immediately filled the entire space.
The observatory has many high-tech equipment that must use electricity, so the Planning Institute generously installed a set of wind power and a set of solar power generation equipment here. Electric lights are also installed in the building to prevent fire.
Dr. Zhong took Zhong Xiaoying to the bottom of the stairs. There was a door hidden in the dark, which also used the original security door. Opening the security door, Dr. Zhong turned on the light, which illuminated a downward staircase.
"Father--"
"Go down." Zhong Lizhi said, turning back and locking the door.
The two of them walked down the steps for more than ten floors, and Dr. Zhong turned on another light. They came to a spacious room - a semi-basement with solid reinforced concrete beams and columns. On the walls,
The ceilings are covered with thick thermal insulation and moisture-insulating materials.
In the room, different strange and bizarre equipment were placed on specially made shelves, all of which were covered with glass covers. Some of them she recognized, such as the studio clock, and some she had never seen before.
, flashing red characters.
Dr. Zhong walked to the wall and looked at the temperature and humidity recorders above - they were products from the old time and space, used to monitor the constant temperature and humidity environment in the semi-basement.
In this basement is housed the most core thing in the Senate's timing system: the reference clock.
There is not one reference clock, but several. One of them is the backup clock on the PHS base station, and the others are the backup navigation clocks on the Fengcheng wheel. It accurately displays the Beijing time and the Beijing time from another time and space.
Greenwich Mean Time.
Because of the importance of recording time, these clocks have been placed in the special warehouse of the Planning Institute in Gaoshanling, and are carefully maintained at constant temperature and humidity. As an important reference time, until the Taipei Observatory was officially established, the Senate's
