Description

TECHNICAL FIELD This application relates to the field of computer technologies, and in particular, to a fever alarm method based on body temperature monitoring and a related device. BACKGROUND A body temperature is a very important physiological sign of human body and a necessary condition for ensuring normal metabolism and life activities. Occurrences of some diseases are often accompanied by an abnormal body temperature. In addition to in initial screening of diseases, the body temperature also plays an important role in many application scenarios such as health and fitness, living habits, and smart home. At present, temperature measurement products include a digital thermometer, an ear thermometer, a forehead thermometer, a body temperature sticker, a temperature measurement bracelet, and the like, and temperature measurement principles of the temperature measurement products are all based on one or more of a thermistor, infrared heat radiation, and a heat flux. However, devices such as the digital thermometer, the ear thermometer, and the forehead thermometer are all used to measure a user's body temperature once, and are not suitable for a scenario in which long-term continuous body temperature monitoring is required. Most of body temperature stickers and temperature measurement bracelets use the temperature measurement principle of thermistor. This requires algorithm compensation, and cannot guarantee accuracy of body temperature detection. Usually, FIG. 1A and FIG. 1B are a diagram of a single-point truncated alarm according to an embodiment of this application. It can be seen from FIG. 1A and FIG. 1B that a wearable device like a body temperature sticker or a temperature measurement bracelet usually uses a single-point truncated alarm mechanism, that is, a body temperature alarm threshold (for example, 37.5°C) is set inside an application (application, APP). When a body temperature measured by the wearable device like the body temperature sticker or the temperature measurement bracelet is higher than the threshold, a fever alarm is generated. However, due to an environmental factor and an individual difference, a body temperature of a user may be higher than 37.5°C in some scenarios. As a result, there is a high probability that the single-point truncated alarm mechanism generates a false fever alarm, causing a puzzle and a trouble to the user, leading to an incorrect misunderstanding of the body temperature by the user, and failing to meet requirements of different users. US 2013/0072765 A1 discloses a body-worn device comprising an accelerometer and a temperature sensor. Further, it includes a power management system to move the body-worn device into a low power state when the body-worn device is not being worn, the power management system determining when the body-worn device is worn based on a combination of sensor data. US 2021/0353236 A1 discloses a system and method for a wearable device for alerting of body temperature of the wearer. US 2021/0278290 A1 discloses a temperature sensor and fever alert generator with tunable parameters. SUMMARY OF THE INVENTION Embodiments of this application provide a fever alarm method based on body temperature monitoring and a related device, so that when a temperature monitoring mode that a user is in is determined, a fever alarm can be generated after it is detected that a body temperature of the user meets a fever condition corresponding to the body temperature monitoring mode. This improves accuracy of the fever alarm. The invention is defined in the independent claims. Additional features of the invention are provided in the dependent claims. In the following, parts of the description and drawings referring to embodiments which are not covered by the claims are not presented as embodiments of the invention, but as examples useful for understanding the invention.

In this application, the wearable device may collect the body temperature of the user. After determining the body temperature monitoring mode that the user is in, the wearable device monitors whether the body temperature of the user meets the fever condition corresponding to the b
