Embodiment Construction

[0014] The two-point temperature sensor and structure of head-mounted or wrist-mounted devices are as follows: Figure 1-2 shown.

[0015] 1. Schematic diagram of multi-point compensation temperature sensor connection

[0016] The hardware circuit of the present invention adopts Nordic's nRF52 series low-power bluetooth MCU, which combines a 64MHz, 32-bit Cotex-M4F processor and a 2.4GHz multi-protocol radio with -96dB RX sensitivity, and 512kB flash memory and 64kB RAM.

[0017] The two temperature sensors used in the present invention are SON1421 digital temperature sensors, which have user-programmable 7-bit (2°C) to 13-bit (0.03125°C) resolution, and have a non-volatile temperature setting that can be programmed by the user. , Lower limit temperature alarm value. The communication interface adopts the Single-Line interface, which requires only a single pin for communication.

Abstract

The invention discloses a dynamic on-line measurement method of human body temperature and a wearable device, which collects the body surface temperature of the human body and the ambient temperature near the temperature measurement point of the body surface temperature at the same time, and calculates the body temperature of the human body by using the following formula: body temperature=A*body surface temperature* Body surface temperature+B*body surface temperature+C*(body surface temperature-environment temperature)-D; where A, B, C, and D are constants. The present invention adopts a two-point temperature measurement method, and according to the measurement data of a large number of people, proposes a real-time dynamic body temperature optimization calculation algorithm, which effectively makes up for the limitations of the single-point indoor body temperature measurement method, realizes dynamic and accurate body temperature measurement, and can accurately reflect the human body Body temperature conditions in different temperature environments.

Description

technical field [0001] The invention relates to the field of human body temperature monitoring, in particular to a dynamic on-line measurement method of human body temperature and a wearable device. Background technique [0002] Existing methods for measuring human body temperature, whether it is an electronic thermometer or a mercury thermometer, are based on single-point measurement and are generally applicable to the majority of the population. The method of compensation estimation includes the method of infrared forehead temperature measurement. This type of body temperature measurement method basically requires the measured population to be at room temperature for more than 7 to 10 minutes, in order to reduce the impact of the outdoor temperature environment on the human body, and the measurement estimate is relatively accurate. [0003] The current body temperature measurement method has certain requirements for the environment of the tested population, and the differe...
