Coordinates China ｜ How to measure space in time "Precision Eye"

Xiaoxin said

In the past ten years, a series of heavy weapons and super engineering created by central enterprises have engraved new coordinates of national development from different dimensions. On September 12th, the online theme promotion of "our ten years@coordinates China" was officially launched. Over the major achievements of representative infrastructure construction and scientific and technological innovation, it shows the courage, courage and wisdom of challenging the limits and challenging the limit.

Without ultra -precision measurement, there is no high -quality equipment manufacturing. The measured accuracy of the nanometer in the "time measurement space" can reach the maximum accuracy of up to ± 0.06 cents, which is equivalent to a 360 -degree circular week, and one of the 60,000 cents at any one degree. The measurement accuracy reaches the limit of the existing detection instrument level. Today, Xiaoxin brings you the sixth issue of the "coordinate China" series theme films, "Chinese Eyes".

Measure space in time?

Yes, you read right!

This may sound sci -fi,

But it is by no means a night.

The key to realizing this magical "time and space conversion"

It is nano -time grid,

One "measures space with time"

Super high precision and high -resolution displacement sensor,

Known as the "Sky Eye", which is called precision positioning and control.

Part1

How to measure space?

In the long measurement history of humans,

"

To use tools with uniform size and shape;

From the measurement of accuracy to 0.01mm,

Go to the historical stage on optical measurement technology ...

Today,

We can even

"Measure space with time."

This secret about "time" and "empty"

What exactly is it?

Imagine a clock

When the second hand rotates on the dial evenly,

It means that it has gone through 360 degrees in space

In terms of time, it took 60 seconds

Move through the uniform speed of the second hand

Let the space and time be associated

Understanding

In the two coordinate systems that exercise relatively at a relatively uniform speed

Observe each other

The difference between one party (displacement)

It is observed by the other party

Time difference

Part2

How precise is the nanometer grid?

Country of the country,

Start at the end.

"Father of Modern thermodynamics" Cairvin

There is a famous conclusion:

"Only by measuring can it be made."

No precision measurement,

There are no precision products, high -level precision measurement technology and precision instrument manufacturing capabilities,

It is an essential condition for the development of high -end manufacturing.

Measurement accuracy of nano -time grid

The highest can reach ± ​​0.06 cents,

It is equivalent to 360 degrees within a week,

Any 1 degree of 60,000, one -degree,

This measurement accuracy has reached

The limit of the existing test instrument level.

The highest legal metering agency in China--

China Institute of Metrology Sciences Two on -site test results

The comparison result of the national perspective benchmark shows,

The accuracy of nano -grille has reached the international leading level.

Part3

How is nano -grille made?

Precision displacement measurement device is used as a core functional component,

Strictly blocked by foreign giants.

Import sensors exist

High price, long stock period, difficult after -sales,

my country's precision displacement measurement field

It is urgent to get rid of the situation of being restrained.

Grille technology

As the first creative result of my country's independent research and development,

By establishing space displacement and

The relationship between time benchmarks,

Use time comparison

To achieve the displacement measurement,

So as to achieve high precision,

The purpose of high reliability measurement.

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

The nano -time grid team since 1996

Put forward the concept of "Time Gas angle sensor",

Adhere to the independent research and development road,

Pass through

The first generation mechanical time grid,

The second -generation magnetic field type,

The third -generation electric field -style grid (that is, "nano -time grid"),

Continue to overcome

"Contradictions to improve measurement accuracy and increase measurement range"

"Errors caused by improving accuracy difficulty traceability difficulties"

"Breakthrough optical diffraction limit to improve resolution"

Three -seater technology.

Cracking product reliability,

Diverse application scenarios,

There are many "block tigers" such as market recognition,

Team develops a high -precision motion control

The grid displacement sensor of oil -resistant dust dust,

Realize the milestone of technology to technology.

April 2021,

GM and Chongqing University of Science and Technology

Co -establishment

GMS National Testing Shizha Technology Co., Ltd.,

It marks the official opening application of the grid results

New stage of service market users,

The industrialization process of nano has accelerated.

Currently, nanoscular grid technology

It has been widely used in high -end CNC machine tools,

Coordinate measuring instrument, servo motor,

Measurement of the measuring meter and semiconductor industry,

And production equipment, automation equipment,

Industrial robots and other fields.

The nanometer grid is gradually filling

Domestic high -end precision displacement measurement fields are blank,

Become a domestic high -end equipment enterprise

The strong backing in the development road.

Facing the forefront of world technology,

For the economy main battlefield,

For major national needs,

Work hard to achieve more new breakthroughs from "from 0 to 1",

String on the journey of dreaming in China!
