"first place in the artificial intelligence trainer competition - lin jinquan!" on september 13, when he heard the chief referee read his name, lin jinquan strode onto the podium and excitedly took the eighth medals, trophies and honorary certificates for the first place in the artificial intelligence trainer competition in the finals of the national vocational skills competition for employees.
this distribution operation and maintenance worker from state grid tianjin chengnan power supply company would never have imagined that at the age of 32, he would create many "firsts" in national competitions: he won first place in the first competition and became a the first gold medal winner in the artificial intelligence trainer competition of the competition became the first employee of the state grid corporation of china to win a gold medal in this competition.
taking root on the front line and asking for directions from “numbers”
in 2016, when lin jinquan graduated from university and joined the company, his team was responsible for the operation and maintenance of the company’s 10 kv power distribution station. at that time, “5 minutes to deal with defects and 1 hour to find a station” was a problem that troubled the distribution station. a long-standing problem for front-line power operation and maintenance personnel.
tianjin chengnan power supply company has more than 8,000 10 kv distribution stations. the lines that need to be checked for a power outage often involve dozens or even hundreds of stations along the line. "old employees are familiar with the specific environment of the line and can quickly find the station location, but it is more time-consuming for newcomers," lin jinquan said.
at the beginning of 2020, lin jinquan decided to ask “number” for directions. he taught himself programming languages and other knowledge, and built a digital application called "station addressing map" from scratch. five months later, this application was finally launched on the "istate grid" app, realizing functions such as station search and one-click direct navigation, completely solving the problem of "finding a station" that troubled front-line personnel in power distribution operation and maintenance.
the "station address map" has made the operation and maintenance personnel of tianjin chengnan power supply company a "living map". "when i discovered that my research and development results could improve the work efficiency of front-line workers in power operation and maintenance, i became even more motivated." lin jinquan said.
today, lin jinquan has more than 20 patented products, and as the first inventor, he has obtained two invention patent authorizations in the field of computer algorithms. when encountering difficult problems in work and life, he always prefers to use "intelligent" methods to solve them. "because intelligent algorithms will make things run more efficiently." lin jinquan said.
in 2020, artificial intelligence trainer will officially become a new occupation and be included in the national occupational classification directory. since then, related competitions have followed one after another. lin jinquan, who has "numbers" in mind, has the opportunity to "go out", go deep into more front lines of competition, and learn new concepts, new knowledge, and new skills in this field.
in recent years, lin jinquan has participated in the national finals of the 4th national telecommunications and internet industry vocational skills competition, the energy big data competition of the digital china innovation competition, and the tianjin "haihe craftsman cup" skills competition electronic data forensics analyst (industrial big data algorithm ) competition, etc., and achieved good results.
"these competitions not only exercise my practical ability, but also test and improve my understanding and application level of digital and intelligent technologies in real projects and simulated environments." lin jinquan said, asking "numbers" again and again for directions. let yourself become more and more confident in joining the digital business.
there are tricks that have been practiced for thousands of times
at the artificial intelligence trainer competition site of the finals of the 8th national vocational skills competition for employees, nearly a hundred workstations were scattered around. lin jinquan stared at the screen at his workstation, sometimes typing on the keyboard, sometimes frowning and thinking.
as time went by, he wrote lines of code smoothly and fed them to the artificial intelligence as instructions, turning it from a "novice" who didn't understand anything to a "smart star".
for the first time, this competition has set up the artificial intelligence trainer competition, which is divided into two parts: theoretical examination and practical competition. it mainly tests the contestants' skills in data analysis and mining, fine-tuning of specific tasks of large language models, and comprehensive application of automatic intelligent driving scenarios.
in lin jinquan’s view, artificial intelligence trainers are people who serve as “teachers” to ai and are gardeners and guardians of the ai world. “being like a teacher treating students requires patience and care.”
in the artificial intelligence trainer competition, the biggest challenge posed to lin jinquan is the large language model. "large models have different 'temperaments' and have different 'understandings' of data. this training process cannot be rushed. adjusting parameters requires teaching students in accordance with their aptitude."
there are "practical moves" to prepare for exams, and "hard moves" to be found in the competition arena. lin jinquan, who participated in the "national competition" for employee vocational skills for the first time, knew that he had to put more effort into checking for deficiencies and honing his skills in order to have the confidence to compete with the national artificial intelligence masters.
during the closed training before the game, in addition to taking the professional coaching courses hired by the company, i seized all the spare time to practice, searched relevant technical cases through the internet, and repeatedly practiced core test points such as fine-tuning of large language model parameters.
lin jinquan also developed an app called "examination assistant" to help with training. "this small program can accommodate 5,000 questions, and has many functions such as marking wrong questions, collecting wrong questions, practicing answering questions, etc... i can achieve good results, and it has a lot of credit!" lin jinquan introduced with interest. he also shared his "tricks" with his teammates, and everyone charged forward side by side.
inspire more employees to join digital innovation
in march 2024, tianjin chengnan power supply company established the "lin jinquan digital innovation studio", attracting 10 core members to join and becoming the company's new front for digital innovation.
as the leader of the studio, lin jinquan makes full use of the innovative data sharing application platform provided by the company and uses report development tools to continuously monitor his learning results. at the same time, he continues to attract and drive more young employees to participate in digital work, and has developed many projects for the grassroots frontline. digital applications that reduce burdens and increase efficiency.
lin jinquan independently developed the "zero-code form tool". users do not need programming skills and can generate a personalized digital product with simple clicks that connects internal and external network data and integrates filling, aggregation, sharing and analysis. , greatly lowering the threshold for digital innovation, allowing digital achievements to benefit every grassroots employee.
in addition to helping colleagues improve work efficiency, lin jinquan and his team members also explored how artificial intelligence technology can be deeply integrated into power distribution operation and maintenance work, lighting up the road to power security with the light of technology. since this year, he and his team members have optimized parameters and upgraded the model of the "severe weather distribution network fault prediction model" recently launched on the company's digital distribution network. the "severe weather distribution network fault prediction model" uses data such as the age of distribution equipment in operation, equipment type, line length, line weak points, geographical distribution, historical faults and meteorological information for training and modeling. it can predict the next three days based on meteorological information. possible high-risk faulty lines.
lin jinquan's goal is to make this application more "smart" through continuous training and "feeding", so as to achieve targeted operation and maintenance by staff, and to identify and eliminate potential line defects in advance.
recently, lin jinquan, who returned to tianjin after the game, has invested in more digital innovation research with his studio members. "through the competition, i have strengthened my determination to learn and progress in the field of artificial intelligence, and i am more convinced that artificial intelligence will have great potential in the high-quality development of our country." lin jinquan said.
