The core technology has been 'card necked', which has sounded the alarm of China's science and technology independent innovation. It seems that small components, it seems to be an unbearable light of national industry.
However, in a general sense of anxiety, one entrepreneur from the Chinese Academy of Sciences, director of the Reliability Center of the Center for Space Applications Engineering and Technology Center of the Chinese Academy of Sciences, founder of the SaiSuke Ding Wei saw the opportunity. 'Market demand forced China's semiconductor industry. With the fast-tracking of the industry, China has greater possibilities for developing autonomous and controllable component products. 'In Dang Wei's view, domestic use has completely replaced imports and reversed the passive situation of domestic technology companies. There are still ways for China.
Detecting the difficulties of a big country
Electronic technology is one of the important signs of the development of modern science and technology, and various components and components that are accompanied by electronic technology can be said to be the most basic and core components in today's industry. Whether it is a cell phone that everybody uses every day, Or spacecraft flying into space, the application of components ranging from civilian to military, can be described as all-encompassing.
The production of components includes many links, but whether it is a simple diode or an integrated circuit with a high technological content, it is impossible to detect this ridge. Dang Wei frankly stated that in the component design process, designers often only pay attention to The functional and technical specifications of components do not give due attention to quality levels and reliability requirements.
The components and components industry contains many complex and critical technologies, including materials, processes, equipment, design, testing and reliability analysis. The adaptability requirements are extremely high, but at present, many domestic testing organizations do not have a complete solution. .
In addition, components from the design selection to the procurement, to the entire system of supervision, acceptance, reinspection and supplementary screening, each link is relatively independent, the closure of information on the stability of components and quality traceability have caused obstacles.
'At present, the testing conditions and level of domestic component selection are limited, but the number is very large, difficult to screen, difficult to test and other pain points exist for a long time. 'said Si-Sink co-founder Qi Min said that these have buried quality problems for follow-up work.
If the test is not closed, the product will often be installed, the function will be wrong during use, the parameters are seriously out of tolerance or even fatal failure, more likely to cause all components around the failure, the loss is huge.
Especially in the military and aerospace fields, the bottleneck of component testing is more obvious. The main performance is the information asymmetry of mutual testing, and the same experiment repeated the phenomenon frequently.
In addition, the overall low level of laboratory testing efficiency is also criticized. According to statistics, although this work is technology-intensive work, but the output of laboratory test results is still mainly artificial, and each person can only complete 5~ 8 component reports, compared with a large number of components, supply and demand are difficult to match. 'And a large number of high-value data can only be used as proof or evidence in paper or spreadsheets, valuable data resources are so low. ' Qi Min said.
Big data sharps penetrate information barriers
In 2016, Dang Wei and the Entrepreneurial Team of the Chinese Academy of Sciences established the Says Library to structure and standardize the data of tens of millions of components, and use the intelligent algorithm of “replacement selection” to replace more domestic components. Imported components and components, While advancing the process of localization in the industry, we have achieved independent control over the core technologies.
So far, SaiScu has successively carried out comprehensive support services for nearly 10 million components for manned space projects, lunar exploration projects and other key projects.
Recently, in order to effectively open up information channels for domestic component inspections, SaiSec has developed a one-stop component inspection platform called 'Hummott Cloud Measurement'. This platform is a collaboration between Saisiku and Chinese Academy of Sciences laboratories. The results of big data technology can conduct 'inquiries' on aerospace and military-type components and provide reliability solutions. Compared with the traditional model, this platform has faster detection and more accurate quality reports.
'In the traditional component detection mode, the unit that has a need for testing takes into account factors such as capabilities, qualifications, and price, and it is difficult to connect smoothly with the laboratory. ' Dang Wei said, 'The testing laboratories are isolated from each other and the testing status Inquiries cannot be made in time, but can only be communicated via traditional telephone and email.'
By setting up testers and lab management accounts, this new test platform can link users and laboratories with component inspection requirements, providing both suppliers and buyers with efficient and real-time, transparent and real-time detection tools, and the 'information wall' within the industry. Completely broken. The R&D team hopes that this platform can integrate information resources of the entire industry in the future.
Under the premise of ensuring reliability, the addition of big data reduces the cost of the entire process by 50% compared with the traditional verification method. Party Wei revealed that the component work in an aerospace engineering task originally required 30 people to complete the collaboration. Now only 3 people are needed. .
In addition, the platform can also use the big data for user portraits to gain insight into the usage habits of both suppliers and buyers in order to achieve 'private customization'. 'We achieved this by transforming component inspection requirements into professionally-implemented 'experimental languages'. From information consultation to programming to selection and recommendation, the one-stop solution for procurement is finally realized. 'Party said.
