Dream quotation

"Learning must be used, as long as the method is right, there is no‘ technical barrier ’.”

"I want to make a point for the development of this industry. We have the ability to do it, and we are willing to work more than others."

When Tang Shuiliang spoke, his hometown Henan accent was very vague.

"In the physical detection of the earth, which one does not traverse the mountains and rivers? There are more places to run, and the accent is naturally 'fish and dragons mixed." Tang Shuiliang explained. He liked physics since he was a child. At the age of 19, he was in the university to fill in volunteers. Three volunteers filled in physics -related majors. In the end, he went to the University of Jilin University with undergraduate and doctoral degrees, and his life was deeply bound with the physical detection of the earth.

How many secrets are hidden in the depths of the earth? Human beings have been asking for cables since ancient times. Earth detectives mainly rely on magnetic fields and gravity fields. They are like the "two eyes" that peele deep in the earth, giving the earth CT, making the underground 2000 meters or even deeper regions "transparent".

The 37 -year -old Tang Shuiliang is the general manager of Zhejiang Diannian Technology Co., Ltd.. He studied the unmanned mobile detection platform equipped with this "two eyes", that is, the special drone of the heavy load. This is the basis of the field of aviation detection. Only by developing more dedicated drones, it is possible to carry various sensors to make unmanned mining, surveying and mapping -this one has always been the field Short board.

Two years ago, in the hands of Tang Shuiliang, the first domestic set of low -air imitation land flight, high -precision drone navigation magnetic gradient measurement equipment- "Hai Dongqing" came out. "Haidongqing" can be briefly understood as the first domestic mining -specific drone, which fills a number of technical gaps such as a large number of domestic large -scale drone aerospace magnetic detection.

Discipline to drones

Improve the accuracy of measurement data

Thousands of miles away, the Senite Right Banner in Inner Mongolia is in the wind season. "Hai Dongqing" is in the 6 mining areas and more than 100 square kilometers of exploration areas there. "If you record the flying route, it is like a parallel line drawing on the surface. Each two lines are separated from 50 meters to 100 meters. By recording the magnetic force, you can find mineral clues." Tang Shuiliang introduced.

In front of it, Tang Shuiliang, a light -colored POLO shirt and sports pants, is not slow and slow, and three sentences are inseparable from "Hai Dongqing". "The 4.6 billion years of the earth is a large magnetic field. Different rocks have different density and magnetic properties. Like the geological structure of mineral resources gathered, a special earth physical signal will be generated." With obvious jump.

"Haidong Qing" is loaded with the airlifting magnetic gradient measuring equipment and other devices, which can capture these weak abnormal signals in large -scale flights, generate data spectrum, and help us speculate on the distribution of underground resources based on the changes in data.

"It can be understood as a machine substitution, replacing manpower with a aircraft, and carrying the detector to patrol the ground." Tang Shuiliang said. Before an unmanned mobile detection platform like "Hai Dongqing" appeared, most of the geological exploration was carried out by artificially carrying the detection equipment to survey signals on the mountains. Therefore, it is often relying on a machete, splitting the thorns under the feet little by little, and sometimes staying in the wild for several months. "The gravity instrument of more than 20 pounds is directly pressed on the body, and the machine does not allow the machine to tilt more than 45 degrees, otherwise the quartz spring will be broken. Therefore, even if you climb the slope of 60 degrees, you need to straighten your back!" Tang Shuiliang said.

The current drone loads the detective equipment. It is a multi -technology superposition, which can bring a disruptive research and development challenge, which is the most fascinated by Tang Shui.

For example, the precision of the aerial gradient measuring equipment is very high. Even the weak magnetism of a iron screw on the aircraft may be read, which can affect the final data. Tang Shuiliang made a significant change of body materials, tried several new materials, and finally replaced iron pieces with aluminum materials. The hardness, density, and abrasion resistance of different materials are different. It needs to be tested to improve improvement and avoid strengths and avoid weaknesses. In Tang Shui's eyes, although their research and development have taken the key first step, the detection of the earth's journey has just started.

Permanent data

To accurately reach the decimal point, 5 digits after the decimal point

During the chat, Tang Shuiliang always paid close attention to our tea cups and helped us continue to get tea in time. Even if we were "brain burned" by many liberal arts students, he just smiled lightly and did not argue.

But soon, this impression was broken by Wang Hui, another member of Tang Shuiliang's team: "Old Tang, somewhat! Only 5 data after the decimal point can persuade him!"

The research and development of "Haidongqing" was stuck because of "real -time positioning" and "post -order positioning". "Just here, we have seven or eight people who spoke, ask questions, and debates." Wang Hui pointed out that Tang Shuiliang's office said that this is the usual way for their team to solve the scientific research card.

"'Hai Dongqing' needs to load the real -time positioning function, and transmits high data to the 'fly control brain' in real time while flying. Wang Hui, who can be responsible for software data analysis, is concerned that the cliff terrain and data are transmitted back and forth in mountainous areas. The time difference will cause the drone reaction lag, which affects the stability of security and data collection. This debate continued for several hours, and the formulas were full of four or five pieces of paper. In the end, they directly picked up the equipment and rushed to the mountain area with an accelerator.

Because of the pursuit of real -time positioning, the measurement data in this experiment, there were errors after the decimal point. This made Tang Shuiliang realize that it does not need to be "dazzling" by the exploring unmanned machine, and it is not the better the intelligent configuration. All intelligent configurations must serve the accuracy of the core data. Therefore, he changed his previous point of view and decided that "Hai Dongqing" no longer uses real -time positioning functions as standard as standard.

On the road of scientific research, Tang Shuiliang was calibrated with similar experiments.

For example, the last time the Qinghai -Tibet Plateau test flight. Due to the thin air, the paddle wings must be turned faster to fly, and the speed is too high, and the fuselage strength is not enough. After the plateau testing, Tang Shuiliang team designed a dedicated "plateau paddle wing" ...

The process of calibration cannot be fast -moving. It needs to be like a walking -like walking person.

Such a hiking journey is long and silent, but Tang Shui is bright. Even in daily life, Tang Shuiliang "quiet" is not like a post -85s: a computer, a few books, a minimalist office, most of the time, he stays in front of the computer. The information of tens of thousands of pages A little bit; get up at four or five in the morning and go to bed at 90 in the evening. Even if you are busy, you will insist on 10,000 steps a day ...

Get through the difficulty

Convert "sample" to "product"

Tang Shuiliang used to work in scientific research institutions. Until 2016, Huang Danian, a doctoral supervisor and a famous earth physicist, tried to quickly realize the transformation of scientific research results through the enterprise model, and founded the only company in Yuyao during Yuyao. This touched Tang Shuiliang, which had been regulated in the "system" at that time.

"I hope that what I have learned can solve practical problems." Tang Shuiliang decided to give up a stable work, joined the instructor's entrepreneurial team, and finally took charge of Zhejiang Diannian Technology Co., Ltd. to turn the scientific research track from the laboratory to the market.

Tang Shuiliang called the results of the school's scientific research as "sample", and the "sample" to the last mile of "product" was actually difficult.

Compared with the daily routine of newspaper topics, experiments, and papers, there are too many uncertain factors for founding enterprises, and the pressure also follows. "We have a new technology, but there is a process of market cognition and acceptance. Then we have to sell ourselves. I will talk and talk to customers on the exhibition, but I am very boring and I will not chat." Tang Shuiliang said Stand under the spotlight yourself. Some people questioned that the technology was not good, and he spent a lot of time organizing all flight data, and made detailed analysis and comparison. Rigidity and professionalism finally persuaded everyone. Those who have heard his speech or report will be impressed by his opening remarks: "Welcome everyone to interrupt me at any time!"

After a report, Tang Shuiliang often "disappeared" for a long time. He did not bring a mobile phone and found a place with mountains and rivers to fish for a long time. This is how Tang Shuiliang relax and decompress, and then set off.

"I want to make a point for the development of this industry. We have the ability to do it, and we are willing to work more than others." Tang Shuiliang said.
