24-hour online How to use the "accelerator" for all nucleic acids in Tianjin?

Tianjin, January 14 (Xinhua News Agency) (Reporters Wang Jinghuai, Liu Weizhen) in the early morning of the 14th, Tianjin's second round of full screening, a total of 44 cases of positive infection, all from centralized isolation points or sealing and control areas. Compared with the "one screening", the detection efficiency of the "second screening" has been greatly improved, and it has been frequently praised by the public. In a megacity with a permanent population of about 14 million people, such a speed, in addition to benefiting from more scientific and efficient organizational coordination, also has to mention the new detection system called "accelerator" by grass-roots personnel.

At noon on the 11th, Lu Jing, deputy senior engineer of Tianjin Big Data Management Center, received an urgent task: to build a new nucleic acid detection information system for the "second screening". The first requirement is that "the people have few operations and orderly and continuous files", and the second is that it must be completed within 24 hours.

After receiving the task, a team of thirty or forty people was immediately formed. The technical team referred to similar systems in other places, carefully selected the type, and finally selected a relatively mature system to improve and upgrade.

Huang Shengxiang, a team member and technician, said bluntly that in order to enhance security, the new system involves a series of hardware resource allocation, software and hardware environment configuration, basic platform initialization and other processes, "under normal circumstances, there is no 10 days to complete."

To this end, the entire team fights all night, server deployment, virtual machine configuration, basic environment construction, organization of front-line collection personnel training, etc., multi-headed and synchronous advancement, all kinds of resources at any time to listen to the deployment of the research team.

That night, all the people stayed in the office. The average age of this team is more than 30 years old, and many of them are new parents. "The 7-year-old called me and kept asking my mom what time it was to get home." Lu Jing said that she could only coax the child to say a few words and then hang up the phone.

The construction of the new system was rapidly advanced, and the technical team repeatedly conducted functional tests and stress tests. "This is important, without stress testing, the system could collapse." Huang Shengxiang said that after repeated parameter tuning, it was finally stress tested to support the safe and stable operation of the system.

On the 12th, the new "two screening" system was launched on time. Citizens no longer need to register their personal information in advance, just hold the ID card, let the sampling personnel scan it with the mobile phone App, and check and confirm it to successfully complete the registration.

"This operation method is simple and clear, we start quickly, eliminating the link of on-site guidance operation and saving everyone's time in line." Ji Baosheng, a street worker in Baodi District, participated in the video training at 11:00 the night before the "second screening", "The operation mode is similar to the WeChat used usually, and you can learn it in ten minutes under the Next App."

A staff member at the Dacheng Yayuan inspection site in Hongqiao District felt that the new system was indeed much faster. "Information entry goes with the shot, an average of five seconds!"

At the same time, the new system also realizes the informatization of the whole process of unpacking, pipe opening, pipe sealing, sealing, transfer, reception, testing, and result uploading.

"At the critical moment of racing against time, making full use of information technology means such as big data and cloud platforms to accelerate the improvement of scientific and accurate detection is of great significance for further clarifying the risk base of the epidemic and fighting the active battle of epidemic prevention and control." Li Lei, chief engineer of the Cyberspace Administration of the Tianjin Municipal Party Committee, said.
