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 measuring method of the body temperature of a human body and wearable equipment. The dynamic on-line measuring method comprises the following steps of acquiring body surface temperature of the human body and temperature of environment nearby a temperature measuring point of the body surface temperature at the same time; and calculating the body temperatureof the human body according to the following formula: the body temperature is equal to A*the body surface temperature * the body surface temperature +B* the body surface temperature +C* (the body surface temperature-the environment temperature) -D, wherein the A, the B, the C and the D are constants. According to the dynamic on-line measuring method disclosed by the invention, a two-point temperature measuring method is adopted, and according to the measuring data of massive crowds, a real-time dynamic body temperature optimizing calculation algorithm is provided, so that the limit of a single-point indoor body temperature measuring method is effectively made up, the dynamic and accurate measurement of the body temperature is realized, and the body temperature situation of the human bodyin different temperature environments can be accurately reflected.

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...
