College entrance examination as promised, infrared thermometer temperature measurement help
Release date: 15:12, July 16, 2020

On the 7th of the national college entrance examination in 2020, more than 340000 candidates from all over the province went to this youth meeting. In accordance with the requirements of the Ministry of education, all localities have taken the most stringent measures to strengthen the examination epidemic prevention, ensure the safety of the examination by the most stringent means, optimize the examination service with the most rigorous attitude, and ensure the fairness of enrollment with the most rigorous procedures. We should take the most stringent measures to strengthen the examination epidemic prevention, strengthen the security in the aspects of transportation, noise control, heatstroke prevention and information security. At the same time, we should strictly carry out the whole process inspection, strictly prevent cheating in the examination, and ensure the safe, warm and fair college entrance examination.

At 7:00 a.m. in Panjiawan station of Kunming metro, the signboard of "Kunming No.1 middle school leaving from exit C" is visible at the elevator entrance and gate. Yang Yang, on duty station manager of Panjiawan station of Kunming Metro Line 3, introduced that this year, "green channel for college entrance examination" will be set up in Kunming Metro. Candidates and their two accompanying families can take the Kunming subway free of charge with the entrance examination permit for 2020. The examinees can also enjoy the priority of temperature measurement and security inspection, the priority of getting in and out of the station, and the priority of passenger affairs. The service centers of Sijiaying station, tangzixiang station, Panjiawan station, Western bus station and other stations near the examination center have set up "service points to help college entrance examination".

Medical kits, masks, mineral water, stationery and other items are prepared for candidates to provide convenience for candidates. At 7:30 a.m. at the entrance of the test site of Kunyi middle school, two lines have been set up at the entrance of the test site according to the needs of epidemic prevention and control this year Infrared thermometer Fast track: when the examinees walk through the passage at an interval of 1 meter, Infrared thermometer The temperature of the examinee will be quickly and automatically identified. At 8:00 a.m., the examinees enter the examination room with their admission cards, ID cards and printed "health green code". Although the admission under the epidemic situation is more complicated than in previous years, the speed at the entrance of the examination site is still very fast, with complete certificates, and each person can enter in about 5 seconds.

The college entrance examination in 2020 is a college entrance examination under the background of the normalization of epidemic prevention and control. For this reason, besides the function of selection and evaluation, it has more flavor and expectation. Don't be nervous, come on "You must be OK!" Parents and test takers stood in the safe areas on both sides, waving and instructing. The reporter found on the scene that this year, the new fashion of "separated" examination has become a new trend. There are less hugs and handshakes between examinees and their parents and teachers. Instead, there are no contact refueling methods such as "watching" and "heart to heart" in the air. Senior three teachers of Changle experimental middle school in Yunnan Province wore red T-shirts with the words of "gold medal" and "invincible" to send the students a "good start".

Feng Shuirong, a teacher at Changle experimental middle school in Yunnan Province, said: "our school is a boarding school. Our teachers spend the last few days with the whole course, and the students in the last month are more energetic." Although the two brothers and sisters of Ms. Li's family studied in different high schools, they were all assigned to the test site of Kunyi middle school. The test room was still two adjacent to each other. Outside the examination room, she kept four large bags beside her waiting for the children. These were the "supplies" she prepared for the children when she got up at 5:00 in the morning. The bags contained biscuits, fruits, mineral water, umbrellas, masks and medicines. "I hope we can do our best to provide logistics services in these two days, so that they can rest assured of the examination." In addition to the common family style sending for examination and accompanying examination, there are some special phenomena in the army of sending for examination.

The epidemic has delayed the college entrance examination by one month. It is not easy for the candidates this year. I'm also moved to see that they are calm and confident to enter the examination room. " A grandmother with a SLR camera on her back told us that her lens sometimes aimed at the vigorous candidates and sometimes at the parents who showed concern. "I want to record this moment with my camera and send the best wishes to the children in my own way." I didn't expect it. Under the strictest college entrance examination, there are so many warm little details in the examination room. Don't worry, there's more down there! At 9:00 a.m., people in the national education examination command center of Yunnan Province on the second floor of the Provincial College of enrollment and examination were quiet and busy, and the real-time video images of the examination centers around the province were clearly switched on the large screen.

Infrared thermometer The principle of In nature, in addition to the light that can be seen by human eyes (usually called visible light), there are also ultraviolet, infrared and other non visible light. Any object whose temperature is higher than absolute zero (- 273 ℃) in nature radiates electromagnetic wave (infrared ray) at any time. Therefore, infrared ray is the most extensive electromagnetic wave in nature, and thermal infrared ray will not be absorbed by atmospheric smoke and cloud. With the rapid development of science and technology, the use of infrared characteristics, the use of electronic technology and computer software and infrared technology, used to detect and measure thermal radiation. According to the size of the external radiation heat on the surface of the object, the thermal sensor obtains different heat difference. Through the processing of electronic technology and software technology, the image with different light and shade or color difference is presented, which is commonly referred to as infrared thermal imaging. After the heat on the surface of the radiation source is converted by thermal radiation algorithm, the conversion between thermal image and temperature is realized.
