▎ 摘　　要

NOVELTY - The device has a temperature sensor module (1) for collecting temperature information, where the temperature information includes temperature data of an optical component and a detection component. A processor (4) is connected with the temperature sensor module and a control module (3) for receiving the temperature information, and indicating the control module to control a heating module (2) to heat the detection component and the optical component according to the temperature information such that the detection component and the optical component are in a calibration temperature range. The heating module comprises a polyimide heating film, a graphene heating film, a polyethylene terephthalate (PET) heating film and a metal heating film. USE - Device for heating a detection component and an optical component of an infrared temperature measuring device (claimed) i.e. non-contact human body temperature measuring product. ADVANTAGE - The device creates a constant temperature environment for detecting component and optical component of the infrared temperature measuring device, so as to accurately calibrate the temperature environment of the small range, which is good for ensuring the temperature measuring precision of the device and reducing the cost. The control module controls the opening and closing of the heating module, and heating power of each heating module in the open state, so that the detection component and the optical component are in the calibration temperature range. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) an infrared temperature measuring method; and (2) a method for calibrating an infrared temperature measuring device. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a heating device. (Drawing includes non-English language text).
