Along with the development of the information-based industry, intelligent wearing equipment such as intelligent bracelet, intelligent wrist-watch are more and more popularized, and especially intelligent wearing equipment that has the health detection function is especially popular, but does not have the intelligent wearing equipment that can direct sweat pH value detects the function in the current market, is difficult to satisfy current user's demand to health detection.
To this end, the present invention provides a smart wearable device, and in an embodiment of the present invention, referring to fig. 1 to fig. 2, the smart wearable device includes:
an apparatus main body 00;
the PH value detection piece 10 is arranged at a position, close to the skin of a human body, on the equipment body 00, and the PH value detection piece 10 can change the color of the PH value detection piece according to the PH value of the contacted sweat;
the light detection module 20, the light detection module 20 is disposed on the apparatus main body 00, the light detection module 20 is used for detecting the color of the PH value detection piece 10 and outputting a corresponding color detection signal;
the main control module 30, the main control module 30 is disposed in the device main body 00, the main control module 30 is electrically connected to the light detection module 20, and the main control module 30 is configured to determine a PH value of sweat that the PH value detection member 10 contacts according to the color detection signal.
In this embodiment, smart machine can be intelligent wrist-watch, intelligent armlet, intelligent bracelet and intelligent glasses etc. so equipment principal 00 can be intelligent wrist-watch dial plate, watchband, the ring cover of intelligent armlet, the mirror leg of intelligent glasses etc..
In this embodiment, optionally, the PH value detecting element 10 may be directly adhered to the position where the device main body 00 adheres to the skin of the human body through glue or an adhesive; optionally, an opening is further disposed on the device body 00 at a position corresponding to and closely attached to the user, and the PH value detection element 10 may be directly embedded in the opening. In this way, when the user wears the smart wearable device, the PH detection member 10 may be closely attached to the skin of the user so as to contact sweat of the user. Optionally, the material of the PH detector 10 may be polyaniline polymer. The polyaniline polymer is a high molecular special material, can change color when contacting with liquid with different pH values, has long service life, and can meet the long-time requirement of users in use.
In this embodiment, referring to fig. 3, in an embodiment of the present invention, the light detection module 20 includes:
the first photoelectric sensor 21 is arranged on the device main body 00 at a position corresponding to the PH value detection piece 10, and the first photoelectric sensor 21 is electrically connected with the main control module 30;
the light-emitting module 22 is arranged on the device body 00 and faces the skin of the human body, and the light-emitting module 22 is electrically connected with the main control module 30;
the main control module 30 is used for controlling the light-emitting module 22 to emit a first optical signal to the skin of the human body, so that the first optical signal is reflected by the skin of the human body, then penetrates through the PH value detection piece 10, and irradiates on the first photoelectric sensor 21;
a first photosensor 21 for detecting a wavelength of a first optical signal penetrating the PH value detection element 10 and outputting a corresponding first wavelength detection signal; wherein the color detection signal is a first wavelength detection signal;
the main control module 30 is further configured to determine a color of the PH detection element 10 according to the wavelength detection signal, and determine a PH value of sweat that the PH detection element 10 contacts according to the color of the PH detection element 10.
It is understood that in this embodiment, the light emitting module 22 may be composed of RGB lamps, and the color of the first light signal may be set by the developer according to the requirement, and alternatively, the color may be white or green. Since the PH detecting member 10 itself does not emit light, it needs to be irradiated with external light to determine its color. Therefore, the first optical signal emitted by the light emitting module 22 can pass through the PH value detecting element 10 after being reflected by the skin of the human body, and at this time, the color of the first optical signal passing through the PH value detecting element 10 changes correspondingly due to the original color (i.e., the color of the first optical signal emitted by the light emitting module 22) and the color of the PH value detecting element 10, and irradiates the first photoelectric sensor 21. In other words, as long as the color of the first optical signal is fixed, the color of the first optical signal passing through the PH detecting elements 10 of different colors (i.e., the PH detecting elements 10 contacting the liquids with different PH values) is different, and each color is in one-to-one correspondence with the actual color of the PH detecting element 10.
In the present embodiment, the first photosensor 21 may be implemented using a photodiode, a wavelength detection sensor, or the like. The first photosensor 21 may convert the wavelength of the received optical signal into a corresponding electrical signal and output, i.e., output a first wavelength detection signal. The main control module 30 may determine the color of the optical signal currently irradiated on the photodiode according to the first wavelength detection signal output by the wavelength detection sensor, and then determine the actual color of the PH detection element 10 according to a preset optical signal color-PH value detection element 10 actual color mapping table, and then recall the prestored PH value detection element 10 color-PH value mapping table, and finally determine the PH value of the sweat contacted by the current PH value detection element 10.
The actual color mapping table of the optical signal color-PH value detection piece 10 can be obtained by a plurality of experiments performed by research personnel during research and development, specifically, the first optical signal with the preset color is reflected by skin to penetrate through the PH value detection piece 10 corresponding to different PH value colors, then the color passing through the PH value detection piece 10 is collected and recorded, and the steps are repeated in sequence to obtain the actual color mapping table of the optical signal color-PH value detection piece 10. The color-PH mapping table of the PH detection element 10 may be set by a developer according to the material selection of the PH detection element 10.
It can be understood that, in another embodiment, as can be seen from the foregoing, the color of the first optical signal emitted by the light emitting module is fixed, so that a developer may directly preset an optical signal color-PH mapping table in advance in the main control module according to the foregoing experimental process, so that after the main control module determines the color of the optical signal currently irradiated on the photodiode according to the first wavelength detection signal, the main control module directly determines the PH value of the sweat contacted by the current PH detection element according to the preset optical signal color-PH mapping table, thereby reducing the number of corresponding program code to be executed, and increasing the execution speed of the program.
Therefore, in practical application, the intelligent wearable device can realize the detection of the PH value of sweat of the user when the user wears the intelligent wearable device, meets the requirement of the user on the health detection function of the intelligent wearable device, and improves the convenience and the experience of the user in using the intelligent wearable device.
Alternatively, the number of the PH detecting members 10 is plural, and the number of the first photosensors 21 is plural. The light emitting module 22 may be provided on the device body 00 at a position facing the skin of the human body. Referring to fig. 2, taking the device body 00 as a watch dial as an example, a plurality of PH value detecting pieces 10 may be disposed at the bottom of the dial, and a light emitting opening is disposed at a position on the dial corresponding to the light emitting position of the light emitting module 22, and a detecting port corresponding to the first photoelectric sensor 21 is disposed at a position of the PH value detecting piece 10, so that the first optical signal emitted by the light emitting module 22 passes through the plurality of PH value detecting pieces 10 after being reflected by the skin of the human body and enters the detecting port to irradiate on the corresponding first photoelectric sensor 21. The main control module 30 may determine a plurality of sweat PH values according to the plurality of first wavelength detection signals, and determine a final user sweat PH value according to a certain preset algorithm, for example, an average calculation or the like, so as to improve the accuracy of detecting the user sweat PH value.
The intelligent wearable device comprises a device body 00, a PH value detection piece 10, a light detection module 20 and a main control module 30. Wherein, the PH value detection piece 10 can change the color thereof according to the PH value of the contacted sweat; the light detection module 20 is configured to detect a color of the PH detection component 10 and output a corresponding color detection signal; the main control module 30 is used for determining the PH value of the sweat contacted by the PH detecting element 10 according to the color detecting signal. Therefore, in practical application, the intelligent wearable device can realize the detection of the PH value of sweat of the user when the user wears the intelligent wearable device, meets the requirements of the user on the health detection function of the intelligent wearable device, and improves the convenience and the experience of the user in using the intelligent wearable device.
In an embodiment of the present invention, the main control module 30 includes a main controller and an analog front end electrically connected to the main controller; the first photosensor 21 includes a photodiode; the light emitting module 22 includes a green LED lamp, a red LED lamp, and an infrared LED lamp; the analog front end is electrically connected to the light emitting module 22 and the first photosensor 21, respectively.
In this embodiment, the main controller may be implemented by an MCU (micro controller unit), a DSP (Digital Signal processing chip), an FPGA (Field Programmable Gate Array), or the like. The analog front end can be implemented by using a biological detection dedicated analog front end chip, such as an AFE4404 chip. The analog front end can not only drive the LED lamp to work under the control of the main controller, but also receive the current value output by the photodiode, convert the current value into a corresponding voltage value and then use the voltage value in the form of a digital signal, such as an SPI signal and an I signal 2 The C signal and the like output current detection signals to the main controller. It can be understood that the number of driving chips and current detection devices in the circuit can be effectively reduced by using the analog front-end chip, and the wiring area of the circuit is reduced, thereby simplifying the structure of the device main body 00.
Specifically, it can be understood that, the longer the wavelength of the light signal irradiated on the photodiode is, the larger the current output by the photodiode is, the main controller determines the current value output by the currently detected photodiode according to the current detection signal transmitted from the analog front end, determines the color of the light signal irradiated on the photodiode according to the current value output by the photodiode and the preset current value-wavelength mapping table, and then determines the PH value of the sweat of the user according to the process of the above embodiment. The preset current value-wavelength mapping table can be set by research personnel according to the selection of the photodiode and the content of specification, and is stored in the main controller.
It should be understood from the above description that the smart wearable device determines the color of the PH detection element 10 by identifying the wavelength of the first light signal passing through the PH detection element 10. In an ideal situation, the color of the emitted first light signal is known, and then the main control module 30 may determine the actual color of the PH detection element 10 directly according to the color of the first light signal passing through the PH detection element 10 according to the above-mentioned light signal color-to-PH value detection element 10 actual color mapping table. However, when the user wears the smart wearable device, the device body 00 cannot be guaranteed to be completely attached to the skin of the human body to create a light-tight closed environment. Therefore, the actual first optical signal passing through the PH detection element 10 is easily affected by the ambient light, so that the wavelength of the first optical signal to be passed through the PH detection element is not the wavelength of the first optical signal emitted by the light emitting module 22, and finally the detection result is deviated.
To this end, referring to fig. 3, in an embodiment of the present invention, the main control module 30 further has a signal input terminal for accessing a PH detection trigger signal;
the main control module 30 is further configured to control the light emitting module 22 to stop working when the PH detection trigger signal is not received;
a first photoelectric sensor 21 for detecting the wavelength of the ambient light penetrating the PH value detection element;
the main control module 30 is further configured to, when receiving the PH detection trigger signal, control the light emitting module 22 to emit a first light signal to the skin of the human body, and determine, according to the first wavelength detection signal and the second wavelength detection signal, the PH value of the sweat contacted by the PH value detecting element 10, by the PH value detecting element 10.
In this embodiment, the intelligent wearable device may further be provided with a user trigger module connected to the signal input end of the main control module 30, for example, a user voice module, a key module, a touch module, an interactive module, and the like. Optionally, the user may trigger the primary user trigger module when the user needs to measure the PH value of the sweat, so that the primary user trigger module outputs a primary PH value detection trigger signal, so that the main control module 30 determines that the user currently has a requirement for measuring the PH value of the sweat; optionally, the user may also set the user trigger module to output the PH detection trigger signal once every a period of time, for example, once every 0.5S. So that the host control module 30 continuously confirms the current PH of sweat.
It can be understood that the first photo sensor 21 outputs a corresponding wavelength detection signal according to the wavelength of the light signal irradiated thereon at any time, so that the light emitting module 22 is not controlled to emit light when the main control module 30 does not receive the PH detection trigger signal, that is, at this moment, the second wavelength detection signal output by the first photo sensor is the wavelength of the light signal after the ambient light passes through the PH detection element. In other words, the main control module 30 determines the wavelength of the current ambient light after passing through the PH detection element in real time when the sweat PH detection is not needed, that is, when the light emitting module 22 is not needed to emit light, and determines the color of the actual PH detection element 10 according to the first wavelength detection signal and the second wavelength detection signal received before when the sweat PH detection is needed.
Specifically, still taking the above embodiment as an example, the first photosensor 21 is a photodiode, when the main controller determines that PH detection is not needed, the current signal output by the first photosensor 21 is processed by the analog front end and then output to the main controller, and the main controller sets the current value as the ambient light-light signal wavelength current value. When the main controller determines that the PH detection is required, the main controller determines the current value output by the first photosensor 21 according to the detection result given by the analog front end, and performs corresponding processing on the current value and the ambient light-light signal wavelength current value to determine the color of the first light signal actually passing through the PH detection element 10. So, in practical application, intelligence wearing equipment can eliminate the interference of ambient light to sweat pH value detection, has improved the accuracy nature that sweat pH value detected effectively.
In addition, as can be seen from the above, in the sweat PH detection process of the intelligent wearable device, the influence caused by the ambient light can be automatically corrected, but if the current lighting module 22 fails or other circuits in the circuit fail, the lighting module 22 does not send the first light signal, and then when the main control module 30 processes the ambient light, the ambient light is further processed according to the process of the above embodiment, so that a completely wrong sweat PH value can be obtained.
To this end, referring to fig. 4, in an embodiment of the present invention, the light detection module 20 includes:
the second photoelectric sensor 23, the second photoelectric sensor 23 is disposed on the device main body 00, and the second photoelectric sensor 23 is electrically connected to the main control module 30;
a second photosensor 23 for detecting the intensity of light irradiated on itself and outputting a corresponding light intensity detection signal;
the main control module 30 is further configured to output a fault signal when the light emitting module 22 is controlled to emit a first light signal to the skin of the human body and it is determined that the received light intensity detection signal is unchanged.
In the present embodiment, the second photosensor 23 may be similarly disposed on the apparatus body 00 at a position close to the skin of the user, and at a distance from the PH detecting element 10 so that the light irradiated thereon is not affected by the PH detecting element 10. Alternatively, the second photo sensor 23 may be formed by a voltage dividing circuit including a photo resistor and a resistor with a fixed resistance, and the photo resistor may change the resistance along with the illumination intensity of the light signal irradiated on the photo sensor, so that the main controller may determine the current resistance of the photo resistor and the resistance ratio of the circuit with the fixed resistance according to the voltage value of the voltage signal output by the voltage dividing circuit and the voltage value of the power terminal, and further determine the resistance of the photo resistor, and determine the illumination intensity of the light signal irradiated on the photo resistor according to a preset photo resistor resistance-light intensity mapping table; optionally, the second photoelectric sensor 23 may also be implemented by using an illumination intensity sensor, and the illumination intensity sensor detects the illumination intensity of the light signal irradiated on the second photoelectric sensor, converts the illumination intensity into an electrical signal, and outputs an illumination intensity detection signal to the main control module 30 in the form of an analog signal or a digital signal, so that the main control module 30 confirms the illumination intensity of the current light signal.
As can be seen from the above, when the main control module 30 confirms that the PH detection trigger signal is received, that is, the main control module 30 determines that the PH value of sweat of the user needs to be detected currently, the light-emitting module 22 is controlled to emit light. It can be understood that when the light emitting module 22 does not emit light, the light intensity detection signal detected and output by the second photo sensor 23 is the light intensity of the corresponding ambient light, and when the light emitting module 22 starts emitting light, the first light signal emitted by the light emitting module 22 necessarily causes the current result detected by the second photo sensor 23 to change. Therefore, if the main control module 30 controls the module to emit light to detect the PH value of sweat, and if the current received light intensity detection signal is not changed, the main control module 30 can determine that the current light emitting module 22 may have a fault, and then output a fault prompt signal to a prompt component described below or to an external terminal via a communication component to prompt a user of the current fault. So, through the aforesaid setting, whether normal self-checking can be realized working to light emitting module 22 to intelligence wearing equipment to in time remind the user to maintain when light emitting module 22 trouble.
Furthermore, it is understood that in another embodiment, the master control module 30 further has an ambient light signal input to access the ambient light detection signal. Optionally, a plurality of first photoelectric sensors 21 may be further disposed in the device main body of the intelligent wearable device, a PH value detection element is not disposed at a position where the device main body corresponds to one or more of the first photoelectric sensors 21, and at this time, the ambient light may directly irradiate the first photoelectric sensors 21, so that the first photoelectric sensors 21 detect the wavelength of the ambient light and output corresponding ambient light wavelength detection signals to the main control module 30, and thus, the main control module 30 obtains the wavelength of the current ambient light and the color of the ambient light.
