Body temperature measuring method based on wearable equipment

Abstract

The invention discloses a body temperature measuring method based on wearable equipment. The body temperature measuring method comprises the following steps of: performing sensor data fusion on collected sensor data under the condition of environmental compensation factors; fitting an environment compensation item, the fusion data of the two sensors, a noise deviation item and real data by using apolynomial regression machine learning method to obtain respective weights of the two sensors and influence factors and noise of environmental factors; acquiring the body surface temperature by usingthe weight fitted by the polynomial, and then fitting the body surface temperature and the real body temperature by using a Kalman filter to obtain the nonlinear relationship between the body surfacetemperature and the real body temperature. According to the body temperature measuring method based on the wearable equipment, remote control measurement of human physiological parameters such as body temperature is achieved through the portable wearable technology, and contact infection can be effectively avoided through a continuous detection solution.

Description

technical field [0001] The invention relates to the technical field of body temperature measurement, in particular to a body temperature measurement method based on a wearable device. Background technique [0002] The new coronavirus (2019-nCoV) is mainly transmitted through droplets and contact. Common signs after human infection include respiratory symptoms, fever, cough, shortness of breath, and dyspnea. In more severe cases, infection can lead to pneumonia, severe acute respiratory syndrome, kidney failure, and even death. At present, people in the general public and groups first determine whether there is a risk of infection by measuring body temperature before taking further operations. During the isolation and prevention period, the quarantined person needs to measure the body temperature of the quarantined person; when the sick person seeks medical treatment, the medical staff needs to measure the body temperature Judgment; after enterprises resume work and schools ...

Problems solved by technology

However, compared with the stable body core temperature, the body surface temperature is extremely susceptible to the influence of the surrounding environment temperature, especially in the case of sudden changes in the surrounding temperature, the body surface temperature of the extremities varies greatly. In this case It is difficult for portable devices to obtain the real body temperature of the human body by measuring the body surface temperature, so it is difficult to determine whether the real body temperature is abnormal. For this reason, a body temperature measurement method based on wearable devices is proposed
