In a specific embodiment, the temperature measuring device is provided with temperature measuring gears in which temperature detection ranges of the ultra-low temperature gear, the medium temperature gear, the high temperature gear, and the ultra-high temperature gear sequentially increase, and a human body temperature measuring gear in which the temperature detection range is included in the temperature detection range of the low temperature gear, see table 2 above. Referring to fig. 7, fig. 7 is a schematic structural diagram of distribution conditions of temperature intervals and switching thresholds of different temperature measurement gears of the temperature measurement device according to the present application, when the temperature measurement device starts measuring temperature of a target object, the temperature measurement device is initialized to enter a low temperature gear, and the highest temperature of the target object is further obtained to determine whether the highest temperature of the target object is lower than t 0; if yes, setting a response rate parameter P0 and a detector temperature Tf0, and entering an ultra-low temperature range; if not, further judging whether the highest temperature of the target object is lower than th1 and higher than tl1, if so, setting an ultrahigh response rate parameter P1, entering a human body temperature measurement gear, if not, judging whether the highest temperature of the target object exceeds T2, if so, setting a low response rate parameter P3, entering a medium temperature gear, and if not, entering a low temperature gear. Judging whether the highest temperature of the target object exceeds T0; if yes, setting a high-response-rate parameter P2 and a detector temperature Tf1, and entering a low-temperature gear; if not, entering an ultra-low temperature gear. Judging whether the highest temperature of the target object exceeds Th1 and whether the highest temperature of the target object is lower than Tl 1; if yes, setting a high response rate parameter P2, and entering a low-temperature gear; if not, entering a human body temperature measuring file. Judging whether the highest temperature of the target object exceeds T3; if yes, setting a high response rate parameter P4, starting the attenuation sheet, and entering a high-temperature gear; if not, further judging whether the highest temperature of the target object is lower than t2, if so, setting a high response rate parameter P2, entering a low-temperature gear, and if not, entering a medium-temperature gear.

Judging whether the highest temperature of the target object is lower than t 4; if yes, setting a high response rate parameter P4, and entering a high-temperature gear; if not, entering an ultrahigh-temperature gear.
The response rate parameters P0, P1, P2, P3, P4 and P5 set by the temperature measuring equipment refer to the response parameters of the infrared detector to thermal energy, and specifically include parameters such as integration time and gain rate. Generally speaking, the higher the response rate, the smaller the temperature value represented by the unit gray scale, which means that the temperature can be measured with higher accuracy, but the temperature measurement range is correspondingly smaller. In the present embodiment, the P1 response rate > P2 response rate > P3 response rate, the P4 response rate > P5 response rate, and the ultra-low-temperature-stage response rate P0 are generally set higher, and there is no inevitable relationship between it and several other response rates. Due to the limitation of the manufacturing process of the detector, the conventional detector cannot measure the ultrahigh-temperature target by only reducing the response rate, so that a movable attenuation sheet needs to be added. An attenuating sheet is a device for reducing the energy of infrared radiation, and is usually a mylar sheet with a hole in the middle, a plastic sheet, or an infrared glass sheet (germanium glass, silicon glass, etc.) with a transmittance film layer, or a crystal material sheet, etc.
The ultralow temperature target is measured by the normal-temperature measuring equipment, so that the ultralow temperature target is difficult to measure accurately, and the temperature parameter of the temperature measuring equipment is required to be correspondingly modified by switching from the normal-temperature grade to the ultralow-temperature grade so as to reduce the temperature of the temperature measuring equipment and measure the ultralow temperature target, so that the corresponding temperature measuring precision is ensured.
Among them, T0 and T0 may be set to the same value, but are not normally set so as to avoid causing repeated switching between temperature-measuring shift stages when the temperature of the target object fluctuates just around T0. Generally, T0 is larger than T0, so that a certain buffer area can be ensured for switching between two gears, and repeated switching of temperature measuring gears frequently does not occur. Th1 and Th1, T2 and T2, T3 and T3, T4 and T4 are the same, and Tl1 and Tl1 are the opposite, in general Tl1 will be smaller than Tl 1.
