How can an entire building be sampled in 1.5 hours?The technologist did it with precision calculation

35 floors, 1 elevator, more than 200 people, how to complete sampling in 1.5 hours science and technology men with accurate measurement calculation to do the contribution to the society is not only in the workplace to do big projects, hair high impact factor papers.In fact, each person’s micro-environment, because of your presence to bring about some changes, is a very important contribution.This includes taking some of your knowledge, skills or experience from your area of expertise and turning it into something that actually helps your community.The night before the nucleic acid test on 4th Of July, my husband and I slept for just over two hours.Because the optimization plan was made at midnight, the nucleic acid sampling of the next day was arranged to start at 6 o ‘clock in our community, and our building was the first group, so we had to get up early.According to our plan, we need the first residents downstairs at 5:40.All of our volunteers need to be downstairs at 5:30.The location and division of volunteers were designed by me.Floor has five volunteers, and I as a volunteer on the first floor the elevator is responsible for the plan, in turn, snarling, statistics, the other two people stand in two stair is responsible for the guide line, and a man standing in the position of the entrance guard, is responsible for special circumstances need to press the doorbell snarling several residents, taking on disposal of waste everyone down.Our building is a 35-story tall building with a total of 90 households, among which 74 households have residents and a total of more than 200 people.Moreover, there were originally two elevators, but one of them needed to be repaired and replaced, leaving only one elevator available.There are also some special residents in the building, but it’s all very difficult.As the captain of the volunteer team in this building, I felt it was not easy, so I discussed it with my husband.Probably due to his scientific and technical thinking, his first reaction was to make precise measurements and calculations and design a plan to implement them.On April 1, the first implementation of the plan was basically successful, which gave us a lot of confidence.I felt needed by my neighbors, and it inspired me with a sense of responsibility to keep these 200 people safe.After the first sampling, we planned to further optimize the scheme, and both schemes lasted until early morning.As a college teacher, I think the significance of volunteering is essentially the same as my work, which points to the responsibility and responsibility for the society.As an intellectual, as a member of this community, IT is my responsibility to do this.The specific design process, let Wu Xiaoyong himself to introduce.Wu Xiaoyong I heard shi Liyue said how to design a scheme for safe sampling, at the beginning, it was really difficult.But the idea is to figure out what’s going on, and then list the constraints one by one.My understanding is that the arrangement of time and sequence is very important in this plan, so I decided to go to the building to test it first.I pinched the stopwatch on my phone to see how long it would take for the elevator to travel one floor and how long it would take to climb the stairs to the next.In addition, to ensure a certain amount of waiting space, we plan to use the small garden downstairs as a waiting space.To calculate the maximum number of people waiting for a 2-meter interval, I also went to the small garden to pace the distance.Once you have the data, it’s calculation and design.Shi Liyue first counted the number of households and people willing to take the stairs in the building, and then divided the staircase group and the elevator group based on everyone’s wishes.In the first plan, the classification was not particularly detailed, especially the grouping of climbing stairs, which was only divided into two groups: low area and high area.Make a rough estimate of how long it will take to get down on different floors and in different ways, and then prioritize.The plan is to make sure that you don’t get to the sampling point too fast or too slow.It is easy to gather too fast, which can be solved by orderly calling.Too slow will create a break, and someone needs to fill in immediately.On The 4th, before the second nucleic acid sampling, we made another optimization modification to the scheme.Our building is in the first batch of sampling in the community. We hope to do everything possible to reduce the time spent in our building and provide more time for subsequent buildings to maneuver.Based on our previous experience, we divided the residents who chose to take the stairs into more detailed groups, and made more flexible arrangements to better exert the mobility of the walking stairs.The general principle is “from high to low”, the first group is the high area elevator group, the second group of high area walking group, call number in turn, there are special circumstances and then adjust.Considering that most of the residents on the 1st to 6th floor choose the way of stairs, relatively fast, on the premise of ensuring the safe distance, not restricted by the elevator downstairs “one ladder, one household”, and strong flexibility, I will take this part of the residents as the mobile part, if there is a break, can be timely mobilized to ensure the detection efficiency.In order to ensure efficiency, I should observe the speed of sampling in real time, evaluate the risk of queue accumulation or disconnection in real time, and inform the shi Liyue in charge of calling in the building to adjust the rhythm of calling as needed.I also have a task is to stand in the front of the team, responsible for looking after whether someone two-dimensional code is not smooth, timely help.In addition, one volunteer is familiar with the neighborhood committee, and she is responsible for the connection and coordination between our building and other buildings, while another volunteer is responsible for maintaining the “2-meter interval” queuing order.I want to make an appeal that contribution to society is not just about big projects in the workplace, high-impact factor papers, or other high-class outputs.In fact, everyone’s micro-environment, because of your presence brought some changes, are very important contributions.These contributions are not just about passion, but also about translating knowledge, skills or experience from one’s field of expertise into tangible help for the community in which they work, or into positive change for the rest of society.
