Blessed are the little friends who clicked in
On the talent -
"Left 3 Circles, Right 3 Circles"
"Twist your neck, twist your ass"
"I'm tired of squatting, stand for a while"
This little guy who is "suspected of selling cuteness".
In fact, it was on the Fuxing EMU
A special "inspector"
It is derived from corn in the black soil of the Northeast
Made from 3D printing
The story of its birth
Also from one
Railroad vehicle repairers talked
"Autohome" out of the "high-speed rail people"
2005
Liu Tianyu, a young man from Tianjin in his early twenties
Just graduated from an automotive college
Stand at the crossroads of life
Liu Tianyu may not have thought of it
He's about to come across one
Truly loved
And dedicated nearly 20 years of youthful career
Born in "Autohome"
Parents in the car factory
The sound of banging and banging
and laughter under the face of the oil sludge
accompanied Liu Tianyu's growth
Therefore, he is also right
The "cradle" of China's automobile industry
Changchun City, Jilin Province
There is a natural sense of intimacy
At that time
CRRC Changchun Passenger of CRRC Group
At the time of the introduction of EMU technology,
A critical period for digestion and absorption
With the memories of childhood happiness
Liu Tianyu came here
A strange and "familiar" city
And so it goes
Opened from "Autobots"
Shift to the role of "high-speed rail man".
It starts with a train loader
After 12 years
Liu Tianyu has been engaged in CRH5 cars,
CRH3
Commissioning of CRH380 series EMUs
After accumulating a wealth of knowledge and practice
What he demands of himself
Getting higher and higher
The beginning of the "Iron Man".
September 2017
The Fuxing EMU is on the Beijing-Shanghai high-speed railway
Achieve commercial operation at a speed of 350 kilometers per hour
It set a new speed record for high-speed rail operation in the world at that time
Walk with speed
It is a localized EMU
Gradually opened the shift to digitalization,
The prelude to the development of intelligence
Also in this year
Liu Tianyu and several others in the workshop
Study and innovate, work well with colleagues
The "Proton Studio" interest group was formed
Collaborative development of information software back-end service programs
From physical to mental
The boundaries between the physical and digital worlds are blurring
A bold idea came out of nowhere:
"If there is communication between man and machine,
Does that mean that the machine can perceive a person
Stretching further afield,
So as to create more possibilities? ”
2020
Beijing-Zhangjiakou Fuxing intelligent EMU
Enter the intense debugging session
Higher level of intelligence and greening
This means more stringent testing standards
In order to ensure that the interior of the cabin is 40°C at a high temperature
The functional indicators of the system are operating normally
A number of hot air blowers are installed on the car
to ensure that the simulation is consistent with the actual environment
Stuffy carriages, cramped working environments,
Frequent hop-on and hop-on trips
……
Stability of staff physical and test data
Facing multiple challenges
Face the challenges at hand
Liu Tianyu suddenly thought:
Since it is difficult for humans to solve, maybe robots can
Just do it!
The beginning of the design
Take into account the machine
It is necessary to move flexibly between the lines of the ground pipe bundle
And ensure smooth passage in narrow areas
The spider-like shape became the first choice
However, due to volume limitations
As a result, the weight of the machine should be light
But the intensity should be high
The process of structural design is a long one
For this
Liu Tianyu taught himself 3D mapping software
On the basis of fully drawing on online open source cases
Designed through a mesh structure
Maximize weight loss
meantime
Liu Tianyu added another one to himself
C language is a compulsory course
to complete the control software design
The cost of making structural parts from metal is too high
It's also slow
It is not easy to adjust the design scheme
Liu Tianyu turned his attention to 3D printing technology
Polylactic acid
This kind of land from the Northeast
The most common material produced from corn
became his final choice
Take advantage of technical information from the open source community
with the workshop already has a 3D printer
The parts of the robot are gradually taking shape
With 3D printers
The last part is poured
One weighs less than 2kg
It can be controlled remotely
and video images are transmitted in real time
The 72-hour endurance hexapod robot was born
to match
Composed of five distributed environmental data acquisition devices,
a compute node,
A display terminal
The unmanned patrol system for the in-vehicle environment was also completed at the same time
As Liu Tianyu said
And that's just the "1.0" version
There is still a lot of room for improvement
Fortunately, this step is a solid step
"You're like Iron Man,
Build your own smart gear! ”
Colleagues joked on the side
While giving him a thumbs up
The re-departure of "Iron Man".
Active learning and exploration
Let Liu Tianyu feel fulfilled and happy
Immerse yourself in the sense of accomplishment that comes with innovation and creativity
He decided to keep taking the big stride
Start again from a new starting point
Realize the re-improvement of personal ability and value
2018
Liu Tianyu has accumulated many years of technical skills
On the basis of the promotion and application of mature work experience
Further research and exploration
Done it with the team
It has completely independent intellectual property rights
"Train Intelligent Debugging and Diagnosis System" project
The independent substitution of EMU debugging process equipment has been realized
It saves equipment procurement and maintenance costs for enterprises
It has brought considerable economic benefits
2019
He is also in the trial production of "Beijing-Zhangjiakou Intelligent High-speed Railway".
play an important role
The intelligent commissioning of the project was realized
It has reached the international and domestic leading level in this field
now
These innovations are being widely used in:
The production and manufacturing of various types of high-speed EMUs of the enterprise
It has laid a solid foundation for the intelligent manufacturing of high-speed rail
"Technical Expert of Central Enterprises"
"CRRC Labor Medal"
……
Scientific design and thinking
Steadfast perseverance and faith
Jointly intertwined in Liu Tianyu
In that ordinary and extraordinary story
and a rare and frequent honor
Innovation and creation, self-reliance and self-reliance
Every one with the spear of innovation
Workers who take on the challenge of the extraordinary
All are "superheroes"
Hats off to you!
