In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "length", "width", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In this embodiment, as shown in fig. 1 and fig. 2, a non-in-ear heart rate monitoring facilities is worn to ear, including heart rate sensor 1, support 2 and LCD, 1 one end of heart rate sensor is provided with support 2, 1 outside of heart rate sensor is provided with LCD and button, 1 inside singlechip, bluetooth module, SMS module and the buzzer of heart rate sensor that is provided with, singlechip and heart rate sensor 1, LCD, bluetooth module, SMS module, button and buzzer connection, the button is connected with the buzzer.

As shown in fig. 3, specifically, the single chip microcomputer is an STM32F103C8T6 single chip microcomputer, the oscillation starting crystal portion of the STM32C8T6 single chip microcomputer adopts an RTC low load mode, the number of pins is 48, the operating frequency is 72MHZ, the single chip microcomputer has 3 ordinary timers and 1 advanced timer, the single chip microcomputer has 2-bit/16-channel ADC analog-to-digital conversion, a 3.3V voltage stabilizing chip is used, the maximum output 300MA current can be ensured, ST-LINK and JTAG debugging and downloading are supported, and the storage resources are 64kb byte FLASH and 20byte Sram.

The measuring principle that the heart rate sensor can distinguish different wavelengths comprises two parts of spectrophotometry and blood plethysmography, wherein the spectrophotometry adopts 660nm red light and 940nm infrared light, and the 660nm red light absorption amount is less according to oxyhemoglobin. The absorption amount of the infrared light with 940nm is large; and (3) on the contrary, measuring the ratio of the infrared light absorption amount to the red light absorption amount by using a spectrophotometry, and converting the detected red light and infrared light which penetrate through the artery blood vessel behind the ear into electric signals. Since the absorption coefficients of skin, muscle, fat, venous blood, pigment, bone and the like for the two kinds of light are constant, the corresponding pulse rate can be measured only by periodically changing the intensity of a signal output by a photodetector due to the periodic change of the concentrations of oxyhemoglobin and hemoglobin in arterial blood with the artery of the blood and processing the periodically changing signals. The degree of attenuation of the transmitted light energy is detected in relation to the cardiac cycle when peripheral tissue is transilluminated with the light beam. When the heart contracts, the peripheral blood volume is the largest, the light absorption amount is also the largest, and the detected light energy is the smallest; the opposite is true at diastole. The change in the amount of light absorption reflects the change in the blood volume. Only the pulsating blood volume can change the intensity of the transillumination energy.

The LCD is an LCD1602 LCD capable of displaying 16 × 02, i.e., 32 characters (16 columns and 2 rows) simultaneously.

The Bluetooth module is an HC-05 embedded Bluetooth serial port communication module, a command response working mode and an automatic connection working mode, and the module can be divided into three working roles of a Master (Master), a Slave (Slave) and a Loopback (Loopback) under the automatic connection working mode. When the module is in an automatic connection working mode, the data which are automatically connected according to a preset mode are transmitted; when the module is in the command response mode, it can execute all the following AT commands, and the user can send various AT commands to the module to set control parameters for the module or issue control commands. The dynamic conversion of the working state of the module can be realized by controlling the input level of the external pin (PIO11) of the module.

The short message module is a sim800 module, wherein r represents receiving t represents sending, when the single chip microcomputer needs to send information, the single chip microcomputer sends the information to the sim800rxd through a 3.1 pin txd for receiving, and after receiving the signal, the sim800 sends the signal to a mobile phone end of a user through a direct txd.

The utility model discloses a support design ensures that the product wears firmly, avoids removing because of the equipment that the motion appears and leads to measuring position deviation. The measuring part of the utility model is designed in the area between the auricle and the apical node, and avoids the interference of other tissues to the measuring result because the subcutaneous part of the measuring part is provided with the matched branch of the posterior auricular artery and the superficial temporal artery; the design of not putting into the ear improves the comfort level of the user and avoids the adverse effect on the hearing effect of the user in daily life; the use is simple and convenient, only needs to use for the first time to connect the Bluetooth, and then can use after wearing.
