Black Technology Refresher Manual

Recording the data, Sheng Mingan and Chen Jingqiu were immersed in building the digital model, and the only sound was the click of the keyboard in the quiet space.

"The technology for surveying large bridges, elevated roads, reservoir landslides and other infrastructure accidents and geological disaster prevention is mainly based on radar technology. Ground radar, phased array radar and satellite radar monitor surface and internal deformation, but the data of these traditional methods cannot Go one step further." Sheng Mingan suddenly spoke about popular science.

Under the premise of one mind and two tasks, it can still maintain the previous super high and super fast hand speed and 100% accuracy!

"However, with the help of radar satellite historical data, combined with mathematical models, the improved InSAR data processing software system is used to detect subtle to millimeter-scale deformation and collapse in the geological interior, and the use of numbers is very intuitive to see signs of warping, infer its collapse speed, and even It is by foreseeing their signs of breakdown that catastrophic accidents can be avoided in time."

Chen Jingqiu and others unconsciously listened to Sheng Mingan's lecture, and even Wang Wei couldn't help thinking seriously about the forward-looking new technology he dictated.

"Huh? Multi-satellite data is used in the same area... Your experiments are quite large."

Wang Wei replied: "There are many people, and there are many research projects."

Chen Jingqiu looked over, he couldn't understand the data Sheng Mingan was processing.

Sheng Ming'an said in a low voice: "The subscript ALOS on the left is the observation data of the Jinzhou Viaduct by the Japanese Earth Observation Satellite for three years, and the ENVISAT frames on the right are European environmental satellites. Different satellites have different bands and resolutions. , access to data will also change, but for us, the impact will not be too great."

Generally speaking, different data obtained by multiple satellites will not have a great impact on the results.

Following Sheng Ming'an's narration, his completed model, imported post-processed data, and graphics processed by various software are presented on the large digital screen one by one. The hidden dangers in a certain section of the Jinzhou Viaduct can be clearly seen in the rail image.

"A total of 9 hidden dangers."

Chen Jingqiu: "Will it collapse?"

Sheng Ming'an: "It is necessary to carry out further InSAR deformation monitoring and data processing for these nine hidden danger areas."

Zhao Da and Wang Ruo stopped what they were doing and surrounded them suspiciously, and Wang Wei couldn't help looking at the big digital screen.

“重整数据。重建数模。”盛明安的语气很冷静，渲染着镇定的情绪：“看InSAR形变监测时序表，从10年8月到13年10月，一共9处隐患的时序表……分别标号J1J9。”

"The InSAR timing table of the J1 area shows that there was a relatively large deformation in November 10, and the data was stable after that, and no large deformation occurred."

"..."

“J4区时序表从10年8月发生形变一直持续到11年的3月，之后数据趋于稳定。”

The animation on the large digital screen changes rhythmically with Sheng Mingan's cold voice and keyboard sound. It is the InSAR timing table established based on the historical satellite radar data in the past. A few program words have been changed to become a more vivid animation. Figure deduction.

First, there is a moving picture of the simulated working state of the satellite radar in the universe. The light green light covers one side of the earth, and then it passes through the rooster-shaped country in an instant. A city like a steel giant.

The moving picture is instantly reduced to a 3D three-dimensional Jinzhou Viaduct, which is placed on the left side of the large digital screen, while a very simple dot coordinate map appears on the right side.

——InSAR deformation monitoring timing diagram.

"Hidden dangers in J9 area, Shenglong area of ​​Jinzhou Viaduct, a relatively large-scale infrastructure project was carried out there last year, and it has not been completed until this year. The InSAR time series shows that geological deformation occurred in J9 area in 10 years, and by 11 years Stop in July."

"However, geological deformation occurred again in November of 12 and has continued to this day."

【Ah, I don't understand. 】

[I just remembered the word 'geological deformation', what does it mean that geological deformation continues to this day? 】

[I feel like Sheng Mingan pretends to understand. [Nose picking]]

[Geological deformation is plane warping!Planar warping of anything has only one result! 】

[What result? 】

"The end result is predictable—"

Sheng Mingan stopped his calculations and stared straight at the large digital screen. Everyone in the laboratory looked at him, and even the follow-up camera held his breath inexplicably in this silent atmosphere.

There was a short comment gap in the noisy live broadcast room, and countless people held their breaths waiting for the answer.

"Jinzhou viaduct collapsed!"

【—Collapse accident! 】

The author has something to say:

The deformation monitoring in the laboratory here is basically artistic processing! 0.1% of the content refers to InSAR deformation monitoring video and foreign radar signal processing laboratories, which are different from radar bases.
