At the same time, because smart bracelets or watches do not have the ability to analyze data independently, it is impossible to independently implement the function of health abnormal reminders, and it is impossible to establish reminders or linkage alarms with family members. Mechanism; further, many smart watches or bracelets must be implemented with the help of another smart phone. Therefore, the operation is more complicated and is not suitable for elderly users.

2) Using the bone conduction technology to monitor the internal sound of the human body in the intelligent mobile terminal, and transforming the sound into an audio signal and extracting the characteristic data of the audio signal for analysis and comparison to realize the health monitoring method, since the bone conduction technology utilizes the bone , nerves, muscles to transmit sound waves, therefore, the bone conduction device used needs to contact the human body, and all the contact sensors have the common problem that wearing a connected body monitoring device during sleep is not comfortable , therefore, affecting the user experience.

detailed description

In order to solve the problem that the non-contact health detection cannot be performed in real time in the prior art, the present invention provides a health monitoring device and method. The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the embodiment of the present invention, a health monitoring device is provided, as shown in FIG. 1, which may include: a wireless signal transmitting module 11, an echo signal receiving module 12, and a processor 13, wherein:

The wireless signal transmitting module 11 can be configured to transmit an ultra-wideband radio signal; the echo signal receiving module 12 is configured to receive an echo signal of the ultra-wideband radio signal; and the processor 13 is coupled to the echo signal receiving module 12 for The echo signal determines the health of the user.

As shown in FIG. 2, the wireless signal transmitting module 11 may include a pulse generator 111, a signal transmitting circuit unit 112, and a first multiplexer 113, where:

The pulse generator 111 can be used to generate a pulse signal and send the pulse signal to the signal transmitting circuit unit 112;

The signal transmitting circuit unit 112 can be configured to modulate the pulse signal and then radiate through the first multiplexer 113 through the transmitting antenna.

In order to achieve multiplexing of existing components, the health monitoring device may be disposed in the mobile terminal, and the above-mentioned transmitting antennas may share the transmitting antenna of the mobile terminal.

In one embodiment, the signal transmitting circuit unit 112 may include an oscillator, a frequency multiplier, and a radio frequency power amplifier for processing the pulse signal.

The echo signal receiving module 12 described above may include: a plurality of receiving antennas and a plurality of signal receiving circuits, wherein each receiving antenna is connected to a signal receiving circuit. That is, receiving through multiple receiving antennas, and for each receiving day The line is connected to a signal receiving circuit, which may include a low noise amplifier, a filter, a mixer and a detector to effect processing of the received echo signal.

In actual implementation, each receiving antenna can send an echo signal to a signal receiving circuit connected to the receiving antenna through a second multiplexer.

In the case where the health monitoring device is disposed in the mobile terminal, the receiving antenna can also share the receiving antenna of the mobile terminal without adding additional receiving sweetness.

In order to apply the health monitoring device to the vehicle so as to monitor the driver's health at any time while the driver is driving, an automobile interface circuit can be provided in the health monitoring device for connecting the health monitoring device to the vehicle.

A health monitoring method is also provided in the embodiment of the present invention. As shown in FIG. 3, the following steps may be included:

Step 301: transmitting an ultra-wideband radio signal;

In one embodiment, the ultra-wideband radio signal may be generated first by the pulse generator and the signal modulation circuit, and then the ultra-wideband radio signal is transmitted through the transmitting antenna of the terminal by the multiplexer.

Step 302: Receive an echo signal of the ultra-wideband radio signal.

The echo signal can be received by multiple receiving antennas in the terminal, that is, multiple echo signals are received. Specifically, the terminal transmits the echo signals received by the multiple antennas through respective signal receiving circuits, and then sends them to the signal receiving circuit. Each port of the signal processing circuit is separately processed.

Step 303: Determine a health condition of the user according to the echo signal.

Considering that when the health status of the human body is affected by diseases, or poisons, drugs, etc., it may cause abnormal breathing of the human being, that is, changes in respiratory frequency, depth, and rhythm. The normal person's breathing is an automatic, uniform, rhythmic and smooth movement of the chest wall and the abdominal wall, and the interval is equal. Therefore, the purpose of health monitoring can be achieved by monitoring the breathing state of the user. That is, the echo signal can be converted into a breathing condition of the user; the health condition of the user is determined according to the breathing condition obtained by the conversion.

Specifically, information about micromotions such as the chest wall and the abdominal wall of the human body can be extracted from the echo signal through data fusion. The above breathing conditions may include, but are not limited to, at least one of the following: the magnitude of the breathing movement, the intermittent time of one breath and one breath, and the number of breaths per unit time. That is, test data of indicators such as depth, rhythm, and frequency of human breathing are obtained.

In the judgment of the health condition, the normal breathing interval and the breathing abnormal interval may be preset, because the normal breathing situation is different for different people, and therefore, the custom mode can be set when the user first uses, that is, The test data of multiple indicators in normal breathing can be collected multiple times at different times, and the average value of the normal values of these indicators is used as a preset normal interval of the user's breathing, and can be preset by referring to medical statistics. One or more respiratory abnormalities, for example, a normal breathing interval, a respiratory abnormality interval 1, and a respiratory abnormality interval 2.

In the case where the normal breathing interval and the breathing abnormal interval are set, the converted breathing condition can be compared with the preset normal value interval; if it is in the normal value interval, the user's health condition is determined to be good; if not, it is normal. The value interval determines that the user's health status is abnormal. Further, after determining that the health condition of the user is abnormal, an abnormal interval in which the health condition of the user is located may be determined; and a processing strategy corresponding to the abnormal interval is generated according to the determined abnormal interval.

For example, the breathing value obtained according to the echo signal is compared with the preset normal breathing value interval, the respiratory abnormality interval 1 and the respiratory abnormality interval 2, thereby determining which interval belongs to, and according to the comparison result, the user is correspondingly Reminder. For example, you can use the following methods to alert:

1) When the test data belongs to the preset normal value range, only the health status of the terminal is good, and the user is not reminded, and the stored historical data can be manually viewed only when the user needs to view the data;

2) When the test data belongs to the respiratory abnormality interval 1, the terminal sets a reminding function to remind the user, and simultaneously sends the test data and the analysis result to the emergency contact mobile phone preset by the user through the short message;

3) When the test data belongs to the breathing abnormal interval 2, the terminal sets the wake-up function to wake up the user, and automatically dials the emergency contact mobile phone preset by the user, and simultaneously sends the current location information of the user to the emergency contact preset by the user.

In order to better illustrate the present invention, a specific embodiment is also provided to explain the above health monitoring method, but it is noted that the specific embodiment is only for better illustration of the present invention and does not constitute an improper use of the present invention. limited.

The inventors considered that when the health state of the human body is affected by diseases, or poisons, drugs, etc., it may cause abnormal breathing of the human, that is, changes in respiratory frequency, depth, and rhythm. The normal person's breathing is an automatic, uniform, rhythmic and smooth movement of the chest wall and the abdominal wall, and the intervals are equal. Therefore, health monitoring can be achieved by monitoring the user's breathing status.

In this embodiment, a health monitoring method and a mobile terminal having a health monitoring function are provided, and the non-contact type sensor is used in combination with a non-contact sensor using an ultra-wideband wireless communication technology to realize non-contact health monitoring.

Because the transmission power of the ultra-wideband wireless communication device is very small (less than 1 mW), the working time of the system power supply can be effectively extended. Further, since the transmission power is small, the electromagnetic wave radiation has little influence on the human body, so that the user can be solved. I hope to place a high-power RF device around me.

The above health monitoring method may include the following steps:

Step S1: The user needs to set a custom mode when using the first time, that is, the test data of multiple indicators during normal breathing can be collected multiple times at different times, and the terminal software can take the average value of the normal values of these indicators as a pre-predetermined value. The normal value interval of the user's breathing is set, and one or more breathing abnormal intervals may be preset by referring to the medical statistical data, for example, setting the respiratory abnormality interval 1 and the respiratory abnormality interval 2;

Step S2: After the user selects to enter the preset custom mode, the terminal enters the health monitoring state. At this time, the baseband chip control terminal transmits the ultra-wideband radio signal, and uses the transmitting antenna shared by the multiplexer and the mobile terminal to transmit the electromagnetic, and simultaneously utilizes The multiplexer shares the antenna receiving antennas of the terminal itself with the non-contact sensor and the terminal, and receives the echo signals in multiple ways;

Step S3: The terminal extracts the echo signals received by the plurality of antennas through respective signal receiving circuits, and then sends them to the ports of the signal processing circuit for processing, and then performs data fusion to extract the chest wall and the abdominal wall of the human body. Micro-motion information, such as: the magnitude of respiratory motion, the intermittent time of one breath and one breath, and the number of breaths per unit time, that is, test data for obtaining indicators such as depth, rhythm, and frequency of human breathing;

Step S4: The terminal stores the data, and compares with the preset normal breathing interval, the respiratory abnormality interval 1 and the respiratory abnormality interval 2, and further determines which interval belongs to;

Step S5: according to the result of the comparison, the user is prompted accordingly;

Specifically, you can follow the rules below to alert:

Based on the foregoing health monitoring method, an embodiment of the present invention further provides a mobile terminal. The mobile terminal may include: a baseband processing and storage circuit portion, a wireless communication radio frequency circuit portion, a power management circuit portion, a clock management circuit portion, and a non-contact sensor, etc. The following sections are described below:

1) The baseband processing and storage circuit portion may include: a baseband processing chip, a signal processing circuit, a memory, a pulse generator, and the like. The baseband processing chip not only synthesizes the baseband signal to be transmitted but also decodes the baseband signal received from the radio frequency module, and also controls and manages the entire terminal; the signal processing circuit is connected to the non-contact sensor for processing Health monitoring data collected by non-contact sensors. The memory is used to store user-defined data and data collected by the sensor. A pulse generator is used to generate the pulse waveforms required for ultra-wideband wireless communication.

2) The radio communication radio circuit part is configured to modulate the digital baseband signal and transmit it to the base station, and demodulate the wireless signal received from the base station and transmit it to the baseband chip for processing, that is, realize the functions of the call and data services of the general mobile terminal. .

3) Power management circuit section for providing power and power management to other parts of the terminal.

4) A clock management circuit portion for providing a reference clock for the baseband processing chip, the wireless communication radio frequency chip, and controlling synchronization and timing in the ultra-wideband wireless communication system.

5) The non-contact sensor part mainly includes: a signal transmitting circuit unit based on an ultra-wideband wireless communication technology, a plurality of signal receiving circuit units, and a multiplexer. The pulse generated by the pulse generator is modulated and transmitted, and the echo signal is received; the echo signal is filtered, amplified and detected and sent to the signal processing circuit for processing.

In the present embodiment, the multiplexer is used to share the antenna between the non-contact sensor and the mobile terminal, which saves space and volume of the terminal, and also saves cost. Moreover, by using the plurality of receiving antennas of the terminal itself to simultaneously receive echo signals from various directions, the accuracy of the obtained measurement data can be improved.

The above health monitoring method can be applied to a mobile terminal, and can also be applied to a device such as a car. The following two examples are respectively described in the mobile terminal and the automobile, as follows:

Example 1

It is used in handheld mobile terminals such as mobile phones and tablet computers. Specifically, the following steps may be included:

S1: The user chooses to enter the health monitoring mode, and after confirming the startup monitoring, the terminal starts to transmit the ultra-wideband wireless pulse signal and extracts relevant information from its echo signal for processing.

For example, breathing is the process of gas exchange between the body and the external environment, that is, the process of inhaling oxygen and exhaling carbon dioxide. The normal person's breathing is an automatic, uniform, rhythmic and smooth movement of the chest wall and the abdominal wall. The interval is equal, and the adult is about 16 to 20 times per minute. When there is a disease, it can cause changes in breathing depth, frequency and rhythm.

The terminal transmits a repeating ultra-wideband wireless pulse to the space through the antenna. During the propagation of the electromagnetic wave, part of the electromagnetic wave is reflected by the user who is breathing and then returned, and then received by the terminal antenna, which is an echo signal. The echo signal is filtered, amplified and detected and sent to the signal processing circuit for processing, which can extract information about the depth, frequency and rhythm of the human body.

Wherein, the depth of breathing, that is, the amplitude of breathing, may be calculated based on the difference between the user's exhalation detected by electromagnetic waves and the distance between the inhalation and the terminal; the distance from the terminal when the user exhales or inhales may be based on electromagnetic waves. The time required to propagate from the terminal to the human body (ie, half of the measured arrival time of the echo signal) is multiplied by the speed of light.

The frequency of breathing can be obtained according to the total number of breaths per minute measured per minute, that is, the breath distance and the inspiratory distance are counted once per measurement, and the sum of the counts in one minute is the frequency of the user's breathing.

The rhythm of breathing can be measured by the time interval between the measured set of one breath and the next breath. When this time interval is uniform and the value belongs to the time range 1 (the data setting when the user can normally breathe according to the medical data and the preset custom mode) is normal breathing; when the time interval is uneven and greater than the time range 2 ( It may be difficult to breathe according to the medical data setting; when this time interval is greater than the time range 3 (which can be set according to medical data) and the amplitude of the measured breath continues to be 0 at this time, it is determined to be an apnea or a sudden stop.

In this step, the user can set the user's custom mode when using for the first time, that is, the test data of each indicator when collecting his normal breathing is collected and stored at different times, and the terminal software performs data fusion after the normal values of these indicators are Set the user to breathe the normal interval; and refer to the medical statistics to preset the respiratory abnormality interval 1 and the respiratory abnormality interval 2 at the same time.

The normal breathing interval and the abnormal interval of the user may include: a judgment interval of the respiratory deepness, the respiratory frequency, and the respiratory rhythm index. That is, it is possible to comprehensively determine whether the user is breathing abnormally through a plurality of indicators.

Among them, the respiratory abnormality interval 1 can be defined as the dyspnea interval, that is, the medical statistical indicators such as the depth, rhythm and frequency of the human body when the dyspnea is difficult, and the values of the indicators when the user is breathing normally set the interval. The respiratory abnormality interval 2 can be defined as an apnea or sudden pause interval, that is, the interval is set according to the amplitude of the human body's breathing when the human body experiences apnea or sudden arrest.

When the custom mode is set successfully, the user only needs to open the health monitoring software every time he uses it, and then choose to enter the health monitoring mode. The terminal will automatically start transmitting the ultra-wideband wireless pulse signal and extract relevant information from its echo signal and process it, which is relatively simple to operate, and therefore more suitable for elderly users.

S2: The terminal compares the processed signal with a preset value set by the user.

The reference set value preset by the user is the threshold of the above-mentioned normal breathing interval, respiratory abnormality interval 1 and respiratory abnormality interval 2. The health monitoring data is compared with the preset reference value set by the user in real time to determine that it belongs to the above three areas. Which interval is in between?

S3: According to the comparison result, different risk levels are divided, and the user is reminded in different ways according to different levels of health monitoring risk.

If the test data belongs to the normal breathing interval, the health status is good only in the terminal, and the user is not reminded that the user needs to manually view the stored historical data when viewing the data;

If the test data belongs to the above-mentioned respiratory abnormality interval 1, that is, when the user has difficulty breathing, it is divided into the risk level I. At this time, in addition to setting the normal ringing tone reminding function to remind the user, the terminal will also test the data and analysis when the breathing is abnormal. The result is sent to the user's preset emergency contact mobile phone by SMS;

If the test data belongs to the above-mentioned respiratory abnormality interval 2, that is, when the user has an apnea or a sudden stop, it is classified as risk level II, and the terminal activates the wake-up function (ie, turns on the continuous maximum volume ringing and vibrates to wake up the user). The user's preset emergency contact mobile phone is automatically dialed, and the current location information of the user is simultaneously sent to the user's preset emergency contact. That is, once a major change occurs in the vital signs of the user using the monitoring terminal, the terminal first strives to wake up the user, and ensures that the user is notified of the contact at the first time while preventing the danger from occurring, and strives for the rescue time.

S4: Continuous monitoring until the user closes the health monitoring mode.

S5: The user can choose to upload the health monitoring test data to the data center of the health service platform system in real time. The health service platform system can provide real-time health management for the user and establish a health file. Through the health service platform, users can get remote help from health care providers. This continuous monitoring and telemedicine plays an important role in the management of chronic diseases.

The embodiment of the present invention further provides a mobile terminal, which is used to implement the foregoing health monitoring method. As shown in FIG. 4, it is a schematic diagram of a hardware scheme of a mobile terminal, wherein the non-contact sensor may be designed based on an ultra-wideband wireless communication technology. The method includes: a signal transmitting circuit unit and a multiplexer L, a signal receiving circuit unit (a signal receiving circuit 1, a signal receiving circuit 2, a signal receiving circuit N), and a multiplexer 1, a multiplexer 2, a multiplexer N .

The baseband processing chip controls the pulse generator to generate the required pulse to be sent to the signal transmitting circuit unit. The signal transmitting circuit unit includes an oscillator, a frequency multiplier and a radio frequency power amplifier, and the pulse generated by the pulse generator is modulated by the feed line and The device L is radiated through the transmitting antenna of the terminal.

The plurality of receiving antennas of the terminal start to receive the echo signals, and pass through the multiplexer 1, the multiplexer 2, ... the multiplexer N respectively enters the signal receiving circuit 1, the signal receiving circuit 2, and the signal receiving circuit N. The signal receiving circuit 1, the signal receiving circuit 2, and the signal receiving circuit N each include: a low noise amplifier, a filter, a mixer, and a detector to remove weak echo signals received on the antennas. The accompanying noise and interference are selected, and after being amplified and detected, the signal processing circuit sent to the terminal baseband circuit performs signal processing and data fusion. The processed test data is saved to the memory.

Example 2

The health monitoring method is applied to an in-vehicle mobile terminal such as an in-vehicle T-BOX. Specifically, the method may include the following steps:

S1: The user selects to enter the health monitoring mode through the mobile phone APP, and confirms that after the startup monitoring, the vehicle network mobile terminal starts to transmit the ultra-wideband wireless pulse and receives the echo signal.

The user can set the user-defined mode when the first time is used. Specifically, the test data of each indicator in the normal breathing can be collected and stored at different times, and the mobile phone APP combines the normal values of the indicators into the data. The user breathes the normal interval and refers to the medical statistics to preset the respiratory abnormality interval 1 and the respiratory abnormality interval 2.

Among them, the respiratory abnormality interval 1 is defined as the dyspnea interval, that is, the medical statistical index such as the depth, rhythm and frequency of the human body when the dyspnea is difficult, and the value of these indicators when the user normally breathes. The respiratory abnormality interval 2 is defined as the apnea or sudden pause interval, that is, the interval is set according to the amplitude of the human body's breathing when the human body experiences apnea or sudden arrest.

Every time the user wakes up the vehicle network mobile terminal before the vehicle travels, when the information interaction with the mobile phone begins, the mobile phone health monitoring APP will automatically pop up a prompt to ask the user whether to enter the health monitoring mode, and the user can select to enter or cancel according to the need.

When the user chooses to enter the personal custom mode and initiates health monitoring, the mobile phone will send a signal to the mobile phone mobile terminal. After receiving the health monitoring instruction, the mobile phone mobile terminal starts to transmit the ultra-wideband wireless pulse and receive the echo signal.

S2: The vehicle network mobile terminal extracts relevant information from the received echo signal and processes the data, and then sends the processed data to the user's mobile phone, and compares with the preset reference value set by the user in the mobile phone health monitoring APP.

The reference set value preset by the user is the threshold of the above-mentioned normal breathing interval, respiratory abnormality interval 1 and respiratory abnormality interval 2. The vehicle network mobile terminal extracts related information from the received echo signal and processes the relevant data to the user's mobile phone in real time, and compares with the preset reference value set by the user in the mobile phone health monitoring APP, and determines that it belongs to the above three. Which of the intervals is the interval.

S3: According to the result of the comparison, different risk levels are divided, and different reminders are given to the users according to different levels of health monitoring risks.

When the test data belongs to the normal breathing interval, the health status is good only in the terminal, and the user is not reminded that the user needs to manually view the stored historical data when viewing the data;

If the test data belongs to the above-mentioned respiratory abnormality interval 2, that is, when the user has an apnea or a sudden stop, it is classified as risk level II, and the terminal activates the wake-up function (ie, turns on the continuous maximum volume ringing and vibrates to wake up the user). The user's preset emergency contact mobile phone is automatically dialed, and the current location information of the user is simultaneously sent to the user's preset emergency contact; that is, once the user's vital signs of the monitoring terminal are changed significantly, the terminal first tries to wake up the user. And to prevent the occurrence of danger while ensuring that the relevant contacts of the user are notified at the first time, and strive for rescue time.

S4: Continuous monitoring during the running of the vehicle until the user chooses to manually close the health monitoring mode; or, when the steam When the car is turned off, the car network mobile terminal enters the sleep mode, the system automatically turns off the health monitoring.

Considering the recent increase in traffic accidents caused by sudden illnesses of drivers, sudden cardiac deaths occur frequently during driving. In this way, users can be continuously monitored while driving, so that users can drive while on the road. Know your physical condition. By integrating the health monitoring function of the vehicle network mobile terminal on the vehicle, the danger during driving can be reduced. It can be set to monitor the health monitoring mode once the vehicle is running, unless the user needs to manually turn off the health monitoring mode due to factors such as the lack of power of the mobile phone, or the system automatically turns off the health monitoring when the car is turned off.

S5: When the vehicle is ignited and started again, the mobile phone health monitoring APP re-prompts the user whether to enter the health monitoring mode, and the user can select to enter or cancel as needed.

S6: The user can choose to upload the health monitoring test data to the data center of the health service platform system in real time. Through the health service platform, users can get remote help from health care providers. Especially when the user suddenly has an abnormality in the process of driving the vehicle, the health service platform staff can assist the driver to obtain emergency rescue.

When the user activates the mobile TV mobile terminal through the mobile APP to enter the health monitoring mode, the microcontroller of the mobile network mobile terminal receives the startup command sent by the mobile phone, and sends a startup health monitoring instruction to the baseband processing chip, and the baseband processing chip receives the instruction. Thereafter, the control pulse generator generates a required pulse signal and sends it to the signal transmitting circuit unit, which is modulated by the signal transmitting circuit and then radiated by the multiplexer L via the transmitting antenna of the terminal.

At the same time, the plurality of receiving antennas of the terminal start to receive the echo signals, and pass through the multiplexer 1, the multiplexer 2, the multiplexer N, and enter the signal receiving circuit 1, the signal receiving circuit 2, the signal receiving circuit N, respectively. Wherein, the signal receiving circuit 1, the signal receiving circuit 2, ... the signal receiving circuit N each comprise a low noise amplifier, a filter, a mixer and a detector for the receiving antenna 1, the receiving antenna 2, ... the receiving antenna N The weak echo signal received is selected from the accompanying noise and interference, and after being amplified and detected, sent to the signal processing circuit in the baseband circuit for signal processing and data fusion.
