Problems solved by technology

Since the body surface temperature of the human body changes greatly at different locations at different times and is easily affected by the environment, using the body surface temperature as the reference temperature will cause large errors in the infrared rapid abnormal body temperature screening instrument, which is not conducive to the screening of abnormal body temperature
Moreover, the correction requires at least two people to interrupt the current work and cooperate, which has a great impact on the work efficiency of personnel and the rapid passage of the crowd.

Embodiment 1

[0024] like figure 1 As shown, a temperature anomaly screening method includes the following steps,

[0025] S1, acquiring the temperature data of the object to be measured;

[0026] S2, judging whether the dynamic temperature threshold is available, if not available, execute S3, if available, execute S4;

[0027] S3, using a fixed temperature threshold as a judgment criterion to judge whether the temperature data is abnormal, if abnormal, alarm and discard the temperature data, if normal, record the temperature data;

[0028] S4, using the dynamic temperature threshold as a judgment criterion to judge whether the temperature data is abnormal, if abnormal, alarm and discard the temperature data, if normal, record the normal temperature data;

[0029] S5, based on the principle of exponential moving average, and update the dynamic temperature threshold according to the recorded temperature data, and return to S1 for the next round of measurement.

[0030] In this specific em...

Embodiment 2

[0045] like figure 2 A temperature anomaly screening system is shown, including the following modules,

[0046] A temperature measurement module, which is used to obtain temperature data of the object to be measured;

[0047] A dynamic temperature threshold available judging module, which is used to judge whether the dynamic temperature threshold is available, if unavailable, is connected to the fixed temperature threshold judging module, and if available, is connected to the dynamic temperature threshold judging module;

[0048] A fixed temperature threshold judging module, which is used to use the fixed temperature threshold as a judgment criterion to judge whether the temperature data is abnormal, if abnormal, alarm and discard the temperature data, and if normal, record the temperature data;

[0049] A dynamic temperature threshold judging module, which is used to use the dynamic temperature threshold as a judging criterion to judge whether the temperature data is abnorm...

Abstract

The invention relates to a temperature anomaly screening method and system and a computer storage medium, and the method comprises the steps: S1, obtaining the temperature data of a to-be-detected object; S2, judging whether the dynamic temperature threshold value is available or not, if not, executing S3, and if yes, executing S4; S3, judging whether the temperature data is abnormal or not by taking the fixed temperature threshold as a judgment reference, if so, alarming and discarding the temperature data, and if not, recording the temperature data; S4, judging whether the temperature data is abnormal or not by using the dynamic temperature threshold as a judgment reference, if so, giving an alarm and discarding the temperature data, and if not, recording the temperature data; and S5, based on the index moving average principle, updating the dynamic temperature threshold according to the recorded temperature data, returning to the step S1, and carrying out the next round of measurement. According to the invention, screening of people with abnormal body temperature in the crowd can still be realized under the condition of temperature drift, and frequent temperature calibration ofthe infrared temperature measurement system is not needed.

Description

technical field [0001] The invention relates to the field of infrared temperature measurement, in particular to a temperature anomaly screening method, system and computer storage medium. Background technique [0002] For malignant infectious diseases such as SARS and new coronary pneumonia, timely identification and proper treatment of infected persons are important means to prevent the continuous spread of the epidemic. Since people infected with this type of disease are often accompanied by symptoms of fever and high fever, screening people with abnormal body temperature in the crowd has become one of the main methods to identify infected people. The infrared rapid body temperature screening instrument can realize non-contact body temperature measurement of a large number of people without affecting the efficiency of pedestrian traffic. This device is suitable for airports, railway stations, subway stations and other places with large crowd density and flow of people. Du...
