/ Zhaomuntong/July 26, 2022 Guangzhou -- If you type in the keyword "broadcast at the hour" on Chengdu Gaoxin's Weibo, you can see the latest information about the number of people waiting in line at nucleic acid testing stations.
Today, the reporter learned from Chengdu High-tech Zone that since the outbreak of local epidemic in Chengdu, the zone has promoted nucleic acid testing work, initially set up more than 140 convenient nucleic acid sampling sites, and fully put into use the 15-minute nucleic acid "sampling circle" mainly based on the sampling cabin. At the same time, in order to save time for the public, the nearby detection sites with fewer people were selected. Chengdu High-tech Zone adopted the form of online hour-by-hour broadcasting, and "AI algorithm" was used to select nucleic acid detection sites with fewer people and release them to the public in real time, helping the epidemic prevention and control with "black technology".
"There are fewer people doing nucleic acid testing here! Chengdu high-tech zone nucleic acid detection sites real-time on the hour." At 14:00 on July 24, the official Weibo platform of Chengdu High-tech Zone, "Chengdu High-tech", once again announced on time, listing more than 20 nucleic acid test sites such as Jiaozi Avenue sampling site, Global Center East Square, Shunjiang Community Health Service Station and so on, with on-site pictures.
The reporter learned that since the outbreak of the epidemic, the background of Weibo has received a lot of private messages, asking which nucleic acid testing sites in the high-tech zone, which sites have a relatively small number of people in line, etc. In order to serve people's livelihood and facilitate nucleic acid testing, the Weibo account of "Chengdu High-tech" began to broadcast the nucleic acid testing site status at the hour in real time from 19:00 on July 18.
"Chengdu High-tech Zone captures the real situation of nucleic acid detection sites and broadcasts it online at the hour to solve the problem of 'uneven hot and cold' queue number of nucleic acid detection sites and balance nucleic acid detection site resources." According to the relevant person in charge of Chengdu High-tech Zone, nucleic acid test sites with less human traffic in the area will be selected every hour through hourly broadcast and released to the public, so as to facilitate everyone to choose nearby sites with fewer people and effectively serve the public. At the same time, through data analysis, it was found that there was a great demand for nucleic acid detection after 8 p.m., and delay service was also carried out at some nucleic acid detection sites.
The move also made many citizens call it "convenient". "That was sweet on the hour! We can feel that every time the epidemic prevention and control in Chengdu is getting more experienced and more convenient." Huang Lin, a resident of the high-tech zone, said, with this reminder, you will know where to do nucleic acid is more convenient, and you will not have to worry about queuing for a long time.
The reporter learned that the following new media of Chengdu High-tech government affairs will continue to publish "real-time broadcast of nucleic acid detection sites on the hour", screen out nucleic acid detection sites with less human traffic in the region and release them to the public, so as to facilitate the public to choose nearby sites with fewer people, and effectively improve the efficiency of nucleic acid detection in the region.
nucleic acid detection point situation on the hour real-time broadcast is how to achieve? "We collected images of each nucleic acid detection site in real time and loaded the 'people density' algorithm to detect the number of people in the queue in real time." Purple light Huachih technology engineer Ran Guilin told reporters.
It is reported that since receiving the task arranged by Chengdu High-tech Zone on July 15, Ran Guilin and his colleagues urgently coordinated deployment, completed the research and development within 48 hours and deployed the facilities and equipment at the nucleic acid detection site.
The reporter learned that the collected scene images will be uniformly transmitted to the epidemic prevention and Control Command center of Chengdu High-tech Zone, so that the video data of all nucleic acid detection sites can be "seen", and the AI algorithm will be used to analyze the queue number of each detection site in real time, so that the video data can be "understood". The queuing data is released to the public through the new media of Chengdu High-tech government affairs, which facilitates the public to choose nucleic acid detection points nearby and at different peaks, effectively reducing the queuing time. "At the same time, we can balance the work intensity of quarantine personnel at each nucleic acid detection site to realize the 'good use' of video data." "Ran said, pointing to a live feed on his computer.
Reporters can see that the computer screen can see all the points of the queue, click into the screen can also be specific to how many people queue. Through the band value displayed at the bottom, it is clear which time period is the queuing peak and which time period has the least number of people.
"AI algorithm can set the detection area on the displayed screen, and only count the number of people in the queue for nucleic acid detection, and do not count the passers-by around." Ran Guilin told reporters that the system effectively supports the epidemic prevention and control platform and urban operation platform of Chengdu High-tech Zone, and helps Chengdu High-Tech zone realize "scientific and technological response to the epidemic".
