Temperature sensing method and terminal of protection cell based on digital twinning

The invention discloses a digital twinning-based protection cell temperature sensing method and terminal, and the method comprises the steps: obtaining the temperature parameter data of reference points inside and outside a protection cell, calculating a first change curve of indoor and outdoor temperatures, building a temperature distribution physical model according to the equipment parameters of the protection cell, calculating the error coefficient of the temperature distribution physical model, and obtaining the temperature of the protection cell. Correcting the output data of the temperature distribution physical model so as to ensure that the temperature data of the whole space of the small chamber is accurately output; and then, according to the first change curve and a normal operation temperature threshold value of equipment in the small room under the condition of no air conditioner, an air conditioner switching scheme of the protection small room under different outdoor temperatures is formulated,
