Furthermore, as shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 5, the signal control module 2 is arranged inside the temperature measurement device body 1, and the movable shielding module 3 is arranged on the temperature measurement device body 1 and is electrically connected to the signal control module 2. In addition, the movable shielding module 3 includes an electronically controlled driver 31 electrically connected to the signal control module 2, a movable shielding structure 32 connected to the electrically controlled driver 31, and an electric motor arranged on the movable shielding structure 32. control heater 33, and the movable shielding structure 32 includes a black substance B (such as an internal black body substance) for generating a predetermined heating temperature through the heating of the electric control heater 33, so as to provide a black body radiation (black body radiation). In addition, the first non-contact temperature sensing module 4 is arranged inside the temperature measuring device body 1 and is electrically connected to the signal control module 2 for measuring an object T to obtain the temperature of the object T. An object temperature information T100. Moreover, the second non-contact temperature sensing module 5 is arranged inside the temperature measuring device body 1 and is electrically connected to the signal control module 2 for measuring the black substance B produced by the movable shielding structure 32 The black body temperature information B100 of the black substance B is obtained by the predetermined heating temperature (or the generated black body radiation).

In this way, the first non-contact temperature sensing module 4 can perform temperature correction through the black body temperature information B100 obtained by the second non-contact temperature sensing module 5 . Furthermore, when the movable shielding structure 32 is driven to a second position by the electric control driver 31, the second temperature measuring angle of view of the second non-contact temperature sensing module 5 can be completely covered by the movable shielding structure 32 black substance B is exposed, and the first temperature measurement angle of view of the first non-contact temperature sensing module 4 will also be exposed by the black substance B, so that the first non-contact temperature sensing module 4 The object temperature information T100 of the object T can be obtained by measuring the object T in the first temperature measurement angle of view. However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

It is worth noting that, as shown in FIG. 3 , when the black substance B of the movable shielding structure 32 is heated by the electrically controlled heater 33 to generate a predetermined heating temperature, the black substance B is measured by the second non-contact temperature sensing module 5 . A radiation temperature value (radiation temperature) obtained after the predetermined heating temperature generated by the substance B will be greater than or equal to that obtained after the predetermined heating temperature generated by the black substance B is measured by the first non-contact temperature sensing module 4 Another radiant temperature value. For example, when the black substance B is formed on the movable shielding structure 32 by coating (or when the black substance B is used as the entire movable shielding structure 32), the black substance B may produce Abrasion causes the thermal radiation efficiency of the black substance B to be low, so the radiation temperature value obtained by measuring the black substance B by the thermopile sensor will be greater than or equal to that obtained by measuring the black substance B by the microbolometer Another radiation temperature value.
