COVID - 19, in the event of an outbreak of traditional way of measuring temperature and wearing masks, registration verification personnel in and out of the way there are many problems: low efficiency, the detection means a single, major is given priority to with the ear of the contact temperature gun and mercury thermometer, temperature gun or any other traditional contact-type temperature measurement device single temperature measuring need 3 to 5 seconds, the traffic can cause personnel gathered, the returning peak further aggravate congestion. Easy to cross infection: The current detection means requires a large amount of manpower and material resources. Traditional temperature measurement means requires close temperature measurement, and there is a lack of disinfection means when many people work continuously. Kindergarten students with potential cross infection risk are more likely to be infected. Data sleep: Traditional temperature measurement method, temperature measurement data cannot be traced back, is not conducive to recording and analysis. Loopholes: Manual paper registration verification is not standard, personnel entering and leaving without verification, historical records are difficult to check, and management has loopholes. Inflexible: At present, reasonable detection means have not been set up in urban public areas such as urban traffic, culture, education and health, industrial and commercial enterprises, etc., so equipment is urgently needed to be flexibly deployed to reduce personnel input.

Temperature of the cervix, under the precondition of non-contact target, accurate measuring the individual temperature data of past the crowd, further integrating the sidewalk brake, access control attendance equipment such as face, will face the body temperature and the corresponding, formed "one person one data" temperature corresponding relation, effectively isolates people suspected abnormal body temperature to distinguish, return to return to work, community, the purpose of inward and outward staff employed in public places, for the prevention and control of epidemic make effective judgment. A sound situation of supervision and co-governance will be formed to ensure people's travel safety and ultimately help realize the fundamental improvement of the epidemic. For all the common people in public places the cervix temperature requirements, standard optimal letter with experience and the accumulation of thermal imaging technology in video surveillance industry, precision, efficiency, technology innovation, easy deployment aspects will implement effective prevention, early warning, timely efficient traffic such as construction goal, at the same time provide a reliable, accurate, the temperature of the visual data for back and analysis in an all-round way.

The design of the thermal imaging temperature detection scheme is guided by the application requirements of epidemic prevention and control, with computer application technology as the means and intelligent prevention and control management as the target. The system can meet the following requirements:

1) High precision temperature measurement is the first principle of the whole system. Combined with the current technical level of the industry and the actual requirements of human body temperature measurement in various scenes in public places, the temperature measurement accuracy can reach ±0.3℃.

2) The high-efficiency system design should be based on the principle of minimizing the impact on public access and social order, without human intervention or contact with the tested objects, maintaining an efficient temperature measurement, ensuring efficient access, minimizing personnel gathering caused by low temperature measurement efficiency, and avoiding cross-infection.

3) Easy to deploy and easy to maintain the system is integrated with graphical UI design. It can automatically detect the running status of any equipment in the system, and display detailed parameters, timely warning problems for staff decision. Stable and easy to use hardware and software, no complex daily operations. The deployment location can be changed quickly and timely.

Rapid body temperature screening in clinical practice, body temperature is an important physiological index. Changes in body temperature usually signal the onset, progression, and outcome of a disease. As fever is a precursor of many diseases, including some infectious diseases, and is of vital importance in the field of public health, especially in disease surveillance, it is also an important indicator for symptom surveillance in countries. With the maturity of detection technology and the continuous improvement of the precision of non-contact thermometer, it has been widely used in human body temperature measurement in public places. Among them, short-range thermal imaging temperature measurement technology has been widely mature and applied in various industries. It has the following advantages:

1. The measurement speed is fast, and the detection time is usually less than 1 second;

2. With high detection rate, the body temperature of multiple people can be detected at the same time;

3. There is no need to contact the tested object during the measurement, and there will be no cross infection due to incomplete disinfection; In public places such as railway stations, subway, high-speed, airport, ferry terminal, schools and other places, usually choose adopts non-contact temperature measuring method, used for inward and outward pedestrians fast measurement, temperature anomalies in personnel, perform rapid intervention, prevent virus outbreak in a public place appear under a wide range of personnel to the spread of dangerous infection. At the same time, to the maximum extent possible to protect the management of the epidemic in public places, to prevent internal personnel from frequent contact with the human body, the occurrence of the virus.

High precision body temperature Detection The novel Coronavirus is commonly found in the initial infected person with weak limbs and fever, etc., so a high-precision non-contact body temperature detection method is needed to distinguish normal persons from those suspected to be infected with high temperature. The measuring accuracy of the temperature measuring device shall not exceed ±0.3℃. The accurate thermometer is used to conduct non-contact temperature detection on the incoming and outgoing personnel, and to quickly detect whether there is high temperature, fever and other abnormal signs. With face recognition and other authentication methods, the vital signs of all incoming and outgoing personnel can be accurately located. In view of the mobility and continuity of people in public places, the non-contact human temperature detection device can carry out continuous temperature measurement for 7*24 hours, so as to strengthen the continuous detection and prevention of people in the detection area.

Anomaly warning and data analysis

Because the transport hub in public places such as the subway, the airport, there are usually more channel gateway, to pass the flow of personnel, through online real-time warning, provides integrated access to personnel for medical, security personnel identity, body temperature and so on multi-dimensional comprehensive information, warning against testing temperature anomalies, and can provide in and out of persons in close contact video data; It can trace its action track through the whole video to improve the response speed of disposal intervention. The system has a whole set of backtracking mechanism, including detection, identity positioning, close contact with people, online real-time monitoring, video backtracking and other functions, so as to trace and analyze the information of relevant people after the event.
