In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Referring to fig. 2, a first embodiment of the invention provides a flow chart of a body temperature detection method. In this embodiment, the body temperature detection method includes the following steps:
step S10, if a body temperature detection instruction is received, acquiring a first electric signal formed by first infrared light radiated by a human body according to the photosensitive diode;
the body temperature detection method in the embodiment is applied to wearable equipment, the wearable equipment can be electronic products such as a smart watch and a smart bracelet, and a photosensitive diode and a light emitting diode are arranged in the wearable equipment, wherein the photosensitive diode is a light detector capable of converting light into current or voltage signals according to a use mode, and the light emitting diode is used for detecting infrared light to form the current signals or the voltage signals and other electrical signals.
Furthermore, in the embodiment, the wearable device is provided with a body temperature detection key for triggering a body temperature detection function, and when the wearable device has a body temperature detection requirement, a user can trigger the body temperature detection function by clicking the body temperature detection key on the wearable device at any time and any place; the user is after clicking the body temperature detection button, wearable equipment can receive the body temperature detection instruction that clicks body temperature detection button and trigger, when receiving body temperature detection instruction, wearable equipment passes through the circuit connection relation control photodiode and opens, understandably, the object of non-absolute zero degree all can outwards radiate the infrared light of certain wavelength, the wavelength of the infrared light of human body outwards radiation is about 9 ~ 10 mu m, consequently, the photodiode after opening can detect the first infrared light of human body outwards radiation, and form first signal of telecommunication according to the first infrared light that detects, in order to convert the first target signal of telecommunication that the compensation obtained into body temperature data after compensating first signal of telecommunication by signal attenuation value, and show body temperature data, the user of being convenient for looks over body temperature data.
Further, the step of obtaining a first electrical signal formed by first infrared light radiated from a human body according to the photodiode includes:
step A, obtaining a voltage signal formed by irradiating first infrared light radiated by a human body on a photosensitive diode according to the photosensitive diode, and determining the voltage signal as a first electric signal; or the like, or, alternatively,
and B, acquiring a current signal formed by irradiating the photosensitive diode with first infrared light radiated by a human body according to the photosensitive diode, and determining the current signal as a first electric signal.
Further, in this embodiment, the first electrical signal includes a voltage signal or a current signal, so that the photodiode in the wearable device can form the voltage signal according to the first infrared ray, and can also form the current signal according to the first infrared ray, specifically, the wearable device controls the photosensitive diode to be opened based on the control relation of the photosensitive diode in the internal circuit thereof, the opened photosensitive diode detects the first infrared light radiated outwards by the human body, it will be appreciated that when exposed to light, saturation reverse leakage current in the photodiode increases substantially, resulting in a photocurrent or photovoltage, and the photocurrent and the photovoltage change with the change of the incident light intensity, therefore, after the wearable device detects the first infrared light radiated by the human body through the photosensitive diode, a voltage signal can be formed on the photodiode by the first infrared light and determined as a first electrical signal; alternatively, a current signal may be formed on the photodiode by infrared light and determined as the first electrical signal. Because wearable equipment is attached to limbs such as user's arm when wearing, therefore during external light can not shine to photodiode, voltage signal or current signal can be detected by photodiode to only the infrared light of human radiation, can avoid external light's interference for body temperature testing result's degree of accuracy is higher.
Step S20, obtaining a signal attenuation value, and compensating the first electric signal according to the signal attenuation value to obtain a first target electric signal;
it can be understood that, because the photodiode is disposed inside the wearable device, and the rear transparent film is disposed between the photodiode and the surface of the human body in this embodiment, when the human body radiates the first infrared light outwards, the first infrared light will be attenuated to a certain extent due to the presence of the rear transparent film, in order to make the detected body temperature data more accurate, the wearable device needs to compensate the first electrical signal after detecting the first electrical signal, specifically, the wearable device obtains a signal attenuation value formed by a difference between the electrical signal detected before installing the rear transparent film and the electrical signal detected after installing the rear transparent film, and performs a preset operation on the signal attenuation value and the first electrical signal, completes the compensation on the first electrical signal, obtains a first target electrical signal, so as to perform data conversion on the first target electrical signal, obtain the body temperature data, and display the body temperature data, wherein the predetermined operation is an addition operation in the present embodiment.

Further, after the signal attenuation value is obtained, the wearable device conducts preset operation on the signal attenuation value and the first target electric signal, specifically, the signal attenuation value and the first target electric signal are subjected to addition operation, the signal attenuation value is compensated on the basis of the first target electric signal, the accurate first target electric signal is obtained, the influence of attenuation when infrared rays penetrate through the transparent film of the rear shell can be avoided, and the accuracy of the body temperature detection result is improved. For example: when the signal attenuation value is 1 and the first electric signal is 9, the first target electric signal 10 is obtained by adding the signal attenuation value to the first electric signal, that is, by adding 1+9 to 10.
And step S30, performing data conversion on the first target electric signal to obtain body temperature data.
Further, after the first target electrical signal is obtained by compensating the first electrical signal, the wearable device needs to perform data conversion on the first target electrical signal to convert the first target electrical signal into body temperature data in units of temperature because the first target electrical signal cannot be output as a detection result. The wearable device can be further provided with a display screen, so that the wearable device can display the body temperature data through the display screen after the body temperature data is obtained through conversion, and a user can conveniently check the body temperature detection result in the display screen after clicking a body temperature detection key to know the current body temperature data of the user; it can be understood that, the wearable device may not be provided with a display screen, but is in board binding with an application program in an intelligent terminal such as a smart phone or a tablet computer through a wireless network, and displays the body temperature data through the display screen of the intelligent terminal. Further, the wearable device can also determine whether the body temperature of the user is abnormal according to the body temperature data, and if the body temperature is abnormal, the wearable device generates body temperature abnormal prompt information so that the user can timely deal with the abnormal body temperature prompt information, for example, a doctor can be seen quickly or fever reducing medicines can be taken.

Further, the wearable device converts the first target electrical signal according to a data conversion relation, and converts the first target electrical signal into body temperature data with temperature as a unit. For example: the wearable device identifies that the data type of the first target electrical signal is voltage, retrieves the voltage as a retrieval formula in a preset data conversion table, determines a data conversion relation between the data type of the first target electrical signal and body temperature data if the data conversion relation converting the first target electrical signal with the data type of the voltage into the body temperature data is retrieved, and converts the first target electrical signal into the body temperature data according to the conversion relation between the voltage and the body temperature.

and step S35, if the body temperature data is greater than or equal to the preset body temperature threshold, outputting body temperature abnormality prompting information.
Furthermore, a display tool used for displaying a certain electronic file on a screen through a specific transmission device and reflecting the electronic file to human eyes can be arranged in the wearable device, so that after the first target electric signal is converted into the body temperature data, the body temperature data is displayed on the display screen by the wearable device and reflected to the visual field of the user, and the user can clearly and accurately know the current specific body temperature condition according to the body temperature data. Further, in order to remind the user in time when the body temperature of the user is abnormal, the wearable device can compare the body temperature data with a preset body temperature threshold value after obtaining the body temperature data, wherein the preset body temperature threshold value is a temperature value set by the user according to actual conditions, specifically, the numerical value of the body temperature data and the preset body temperature threshold value are subjected to difference value operation, whether the body temperature data is greater than or equal to the preset body temperature threshold value or not is determined, and if the difference value between the numerical value of the body temperature data and the preset body temperature threshold value is greater than or equal to 0, it is indicated that the body temperature data is greater than or equal to the preset body temperature threshold value. Further, if it is determined through comparison that the body temperature data is greater than or equal to the preset body temperature threshold, it represents that the current body temperature data of the user exceeds the preset body temperature threshold, and there is a risk of fever, so that the wearable device generates body temperature abnormality prompt information and can output the body temperature abnormality prompt information through a display screen or a speaker to prompt the user, for example, a prompt message of "body temperature abnormality, please note" is output through a speaker in the wearable device.
This embodiment converts first target signal of telecommunication into the body temperature data that uses the temperature as the unit, through converting data for the user can carry out body temperature detection anytime and anywhere and accurately look over current body temperature data, improves the convenience and the degree of accuracy that the body temperature detected, and when user's body temperature data is greater than or equal to and predetermines the body temperature threshold value, the unusual tip information of output body temperature, in order to arouse user's attention and in time carry out proper processing, be favorable to protecting user's health.

Before a signal attenuation value is obtained, when the wearable device is not provided with the rear shell transparent film, after first detecting first infrared light which is radiated by a human body and is not attenuated by the rear shell transparent film through the photosensitive diode, forming a second electric signal on the photosensitive diode by the first infrared light; after the second electric signal is obtained, a rear shell transparent film is arranged in the wearable device, and after the first infrared light which is radiated by a human body and attenuated by the rear shell transparent film is detected by the photosensitive diode, a third electric signal is formed on the photosensitive diode by the first infrared light.
