A temperature compensation method for basic population in human inspection and quarantine system

Abstract

The invention relates to a method for compensating the temperature of the basic population in a human inspection and quarantine system, which includes collecting the display temperature of personnel within the monitoring range in real time; when the first preset time or number of people is reached, calculating the average value of all display temperatures and calculating the difference from the reference temperature , get error fError0. If fError0 is within ±0.3°C, no adjustment will be made; if fError0 is outside ±0.3°C, when the second preset time or number of people is reached, the average value will be calculated to obtain error fError1. If fError1 is within ±0.3°C, no adjustment will be made. Adjustment; if the error exceeds the range of ±0.3°C, count the first n alarm temperatures within 1 hour of starting up, calculate the temperature difference between each mercury re-measurement temperature and the corresponding alarm temperature, and calculate the average value fError2 of the n temperature differences. If fError0, fError1, and fError2 are temperature differences exceeding the error range in the same direction, calculate the mean value Cmpnst=(fError0+fError1+fError2) / 3 as the basic population temperature compensation value. The invention performs real-time statistics on the body temperature of the crowd under the ambient temperature of starting up, acquires the error status of the body surface temperature, and calculates a reasonable compensation value.

Description

technical field [0001] The invention relates to the field of infrared thermal imaging temperature measurement, in particular to a method for compensating the temperature of the basic crowd in a human inspection and quarantine system. Background technique [0002] Different climate or weather conditions will have different meteorological conditions such as ambient temperature, humidity, wind speed, etc., which have different effects on the distribution of human body surface temperature. The traditional infrared human body inspection and quarantine system detects body surface temperature, and then predicts when mercury retests the temperature. , usually the compensation does not consider the ambient temperature change, but only compensates different correction values ​​for different body surface temperatures. [0003] The traditional human body temperature compensation method uses the body surface temperature to calculate the temperature value to be compensated to obtain the e...

[0003] The traditional human body temperature compensation method uses the body surface temperature to calculate the temperature value to be compensated to obtain the estimated value of the human body temperature; this method does not consider the distribution difference of the body surface temperature of the normal population under similar ambient temperatures; it does not consider the human body surface temperature in the air-conditioned environment. Changes in the temperature difference between the temperature and the body temperature, when compensating, there may be changes
