The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.

The inventor finds that the non-contact temperature measurement is easily affected by the current environment state, for example, moisture and carbon dioxide in the environment may attenuate the signal of the non-contact temperature measurement, and further generate the temperature measurement error, which is not favorable for ensuring the measurement accuracy, and please refer to fig. 1, the present invention provides a target temperature detection method, including:
s1: respectively acquiring target temperature associated information of an object to be detected and environmental state associated information of an environment where the object to be detected is located;
s2: and determining the target temperature of the object to be measured according to the target temperature correlation information and the environmental state correlation information. The attenuation of the environment state associated information to a signal of non-contact temperature measurement is determined by acquiring and detecting the environment state associated information, the target temperature is subjected to temperature compensation by acquiring the environment state associated information, the system error when the target temperature is directly determined by the target temperature associated information is reduced, and the detection precision of the target temperature is improved.
In some implementations, the target temperature-related information includes: the radiation output energy and the radiation receiving energy, and the environment state related information at least comprises one of the following: ambient humidity, ambient carbon dioxide concentration. An infrared temperature measurement mode can be adopted, and the working principle is as follows: the method is characterized in that a thermopile far infrared sensor is adopted, one end of the thermopile far infrared sensor receives infrared radiation receiving energy of a target, the other end of the thermopile far infrared sensor obtains a reference temperature, the reference temperature is generally room temperature, when target temperature detection is carried out, temperature difference electromotive force is generated at two ends of the thermopile far infrared sensor, and the tested target temperature is obtained through the temperature difference electromotive force and the reference temperature.
In some implementations, determining a target temperature from the target temperature related information and the environmental state related information includes:
emitting radiation output energy to the object to be detected, and acquiring radiation receiving energy;

the inventor finds that moisture and carbon dioxide in the environment can generate attenuation effect on radiation, and after the radiation transmittance is determined, the target temperature can be determined through the radiation transmittance and the initial temperature.
Since a higher initial temperature represents a larger radiation receiving amount from the target and accordingly a higher target temperature, the target temperature is in a proportional relationship with the initial temperature, and since the lower the radiation transmittance, the more the radiation receiving energy is attenuated, the smaller the radiation receiving amount from the target and accordingly the lower the initial temperature, the target temperature is in an inverse relationship with the radiation transmittance. The inventor finds that the radiation transmittance is related to the target distance, the ambient humidity and the ambient carbon dioxide concentration, so that the target distance, the ambient humidity and the ambient carbon dioxide concentration can be acquired in real time to obtain the real-time radiation transmittance, and the mathematical expression of the radiation transmittance is as follows:
