Twenty years of grinding a "ruler", the time of nanometer grid measures space

The great artifact of the country began at the end.

"Father of Modern thermodynamics" Kaerwin has a famous conclusion: "Only measurement can be made." Without precision measurement, there are no precision products, high -level precision measurement technology and precision instrument manufacturing capabilities. The essential condition.

With the continuous deepening of human exploration of the world, the target targets continue to extend, the measurement purpose has continued to extend, and various measurement technologies have successively appeared on the stage of history. To this day, we can even measure the space with time, which sounds sci -fi, but it is by no means a night.

Based on the current status of my country's precision measurement technology development, the Shizha team from Chongqing has proposed an important academic idea of ​​"time measurement space" based on the "time and space conversion" thinking method, and this was born. "-The Time Gasing Technology realizes the autonomous and controllable of precision displacement measurement technology and devices in my country.

From the exploration of 1996 to the third -generation nanoscular grille comparable to the high -end grating, the twenty -year -old accumulation is successfully developed, and the scientific and technological workers' persistence of independent innovation and China's accuracy has condensed them to break through the customs and seize the section. The courage of hard work shows the spirit of the Chinese people's stubborn struggle and undefeated spirit.

From nothing, it is the courage of "Chongyun Broken Mist"

In the field of precision processing, industrial surveying and control (dynamic measurement), precision displacement sensors are indispensable and important parts, known as the "eye of intelligent manufacturing". Its performance directly determines the accuracy of the processing and manufacturing link. High positioning accuracy, good reliability, and convenient use of precision displacement sensors are widely used in industries such as machine tool processing and detection instruments.

However, as the core functional component of precision displacement measurement devices, it has been strictly blocked by foreign giants for a long time. The import sensor has the problem of high price, long cargo period, and difficulty in after -sales. The domestic replacement of high -end displacement measurements has reached an urgent point.

The key core technologies are or not to buy, buy, or discuss. To achieve breakthroughs in the art, we must rely on independent innovation, need to change research ideas, innovate in principle, and fundamentally solve the problem. It is not easy to achieve a breakthrough from 0 to 1.

In the face of various difficulties, the Tu team faced the difficulties, aiming at the forefront of technology, and climbed the peak. If there is no case to imitate, they will be the pioneer by themselves; without experience, they can take the weight forward; without theoretical reference, they creatively propose the important original academic thoughts of using "time measurement space", named the dream " "Time rail displacement measurement technology" breaks through the precision location detection problem of high -end equipment, and has mastered the independent intellectual property rights of key core technologies for precision displacement measurement.

Scientific and technological workers use responsibility, responsibility, diligence and hard work to achieve a leap from micron to nano -precision, and open up a localized road of high -end core functional components, allowing the smart manufacturing card neck to break the shortcomings and reborn. Autonomous and controllable roads have caused my country's precision displacement measurement field to get rid of the situation of being subject to people.

After years of precipitation and development, Shizha Technology has developed into the iconic achievement of my country's intelligent manufacturing field. It has won 1 second prize of national technology invention, 1 China Patent Gold Award, and 2 first prizes in Chongqing Technology Invention. 12 foreign patents and 25 domestic patents.

From you to you, it is an innovative pursuit of excellence

As the initiative of my country's independent research and development of China's independent research and development, through the establishment of the relationship between the spatial displacement and the time benchmark, the amount of time is the objective advantage of human measurement accuracy. So as to achieve high -precision measurement purposes. It can be understood in popularity as: the two coordinate systems of relatively uniform exercise observe each other, the difference (displacement) of one party is manifested as the difference between the time observed by the other party.

Ten years of grinding a sword, grinding a foot in twenty years.

From 1996, Shizha team put forward the concept of "Shilu angle sensor" and adheres to the independent research and development road. "), Continuously overcome the" contradictions that improve the measurement accuracy and increase the measurement range "," difficult traceability caused by the improvement of precision improvement "and" break through the optical diffraction limit improvement resolution "three technologies, solve the reliability of the product, the application scenario of the application scenario, Diversified and market recognition, etc., have developed high -precision, high -reliability time grid displacement sensors.

How precise is the nanometer grid? In the two on -site test results of the Chinese Institute of Metrology Science and the national angle benchmarking results in my country's highest legal metering institution, the results of the national angle, the accuracy of the nanometer grid reached an amazing ± 0.06 corner second (1 ° equal to 3600 cents), accuracy of accuracy, accuracy The level has reached the limit of the level of the existing detection instrument.

In the long time, the time of the Tu team used the spirit of excellence and meticulous scientists, only competing for the night, and in a laboratory that carried responsibilities and dreams, he persisted and made the "fine cultivation" rejuvenating a new era.

From You to Qiang, it is a great leap to speed up

The breaking of a seedlings requires the appropriate temperature, humidity, environment and high -quality embryo. Similarly, the successful transformation of any scientific research results cannot be separated from the support and help of talents, technology, funds, and policies. "Go out of the laboratory to get the nano -time grid technology to realize industrialization." —— It is not enough to have a beautiful vision alone. It has broken through the technical level and faces the application and market level. Wang Yong, chief engineer of the Nanoshazu project, said, "In April 2021, General Technology Group and Chongqing University of Science and Technology jointly established the GMS National Testing Time Time Time Time Time Time Time Gab Technology Co., Ltd. New stage of users. "

The distance between reality and ideals is approaching step by step. The industrialization process of nano -grille has been accelerated in an all -round way. When nano -grille technology is applied in batches in the fields of CNC machine tools, semiconductor industries, measurement testing, etc., when a Chinese precision ruler solves the problem of high -precision position testing, everyone's hardships Two words with sweat: value! The nanometer grid is gradually filling the gap in the field of high -end precision displacement measurement in domestic high -end precision displacement, becoming a strong backing in the development path of domestic high -end equipment enterprises.

In October 2021, the "large number of nanometer rail displacement measurement technology and devices", as one of the typical cases of 35 representatives of the transformation of scientific and technological achievements, appeared in the national "13th Five -Year Plan" scientific and technological innovation achievement exhibition as the first in the transformation system of innovation and technological achievements A typical case is exhibited, showing the "intelligent manufacturing" level of high -end equipment of China's high -end equipment.

The grid displacement measurement technology appeared at the national "13th Five -Year Plan" scientific and technological innovation achievement exhibition

Through the Wanshui and Mountains, it still needs to be waded in the mountains.

Like Shilu Technology, the initiative independently developed by my country is endless. Scientific research is a rigorous and romantic way. From scratch, from to excellent, and from excellent to strong butterfly, it is the perfect display of the responsibility of Chinese scientific and technological workers "Chongyun Breaking Mist" and excellence. The vivid interpretation of the difficulties of the road of a strong country and daring to work, and every step of footprints was writing and witnessing a great leap again and again.

China is accurate, and central enterprises are wise. Facing the forefront of the world technology, the main battlefield of the economy, and the major needs of the country, countless Chinese scientific researchers and Chinese enterprises have studied and pondered between square inches, and strive to achieve more new breakthroughs from "from 0 to 1". China ’s accuracy is on the dream journey.
