Technical Field

The disclosure relates to the field of signal processing, and in particular, to a first device and a signal processing method.

Background

Along with the continuous enhancement of health consciousness of people, the requirement for health condition monitoring is also gradually increased. Some prior art proposes wearable monitoring devices with data analysis functionality. The monitoring equipment is provided with a plurality of modules needing power supply, the monitoring equipment is required to be taken off and then charged by a charger, and the frequent taking off of the monitoring equipment brings inconvenience to the life of a user, so that the power supply capacity of the monitoring equipment is set larger for reducing the charging times, and the volume is increased. For monitoring devices implanted in a user, the monitoring device cannot be removed frequently, so that a period of time with relatively small influence on the human body, such as charging while the user sleeps, is generally selected. Assuming that the sleeping time of the user is 8 hours, in the case of implanting the monitoring device, the monitoring device needs to store electric energy required for the monitoring device to continue to operate for 16 hours at least within 8 hours, which makes it difficult to reduce the volume of the monitoring device and reduces the comfort of the user after implanting the monitoring device.

Detailed Description

Various exemplary embodiments, features and aspects of the disclosure will be described in detail below with reference to the drawings. In the drawings, like reference numbers indicate identical or functionally similar elements. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

In addition, numerous specific details are set forth in the following detailed description in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art have not been described in detail in order not to obscure the present disclosure.

As shown in fig. 1, the first device may be a wearable device having energy conversion and data analysis functions and worn by the user a. The second device may be an external device having a certain distance to the user a, and may be a server or a terminal device. The first device may communicate wirelessly with the second device.

The second device may charge the first device and control a data analysis process of the first device by outputting the first signal to the first device.

The first device can collect and store physiological data of the user A, analyze the collected physiological data, store analysis results and determine the health condition of the user A according to the analysis results. The physiological data of the user a and/or the analysis result of the physiological data may be transmitted to the second device via the second signal.

The second device can store and analyze the physiological data after receiving the physiological data, and determine the health condition of the user A according to the analysis result. After receiving the analysis result of the physiological data, the first device can store and collect the analysis result in a period of time, and the like, so as to monitor the health condition of the user A.

As shown in fig. 2, the first device is a wearable electronic device, the first device includes a signal transceiver module, a power management module, a flexible memory chip,

The signal receiving and transmitting module is used for receiving a first signal from the second equipment, transmitting the first signal to the power management module when the purpose of the first signal is energy supply, and transmitting the first signal to the flexible memory integrated chip when the purpose of the first signal is data analysis;

The power management module is used for converting the first signal into electric energy for storage when receiving the first signal, and supplying power for the signal receiving and transmitting module and the flexible memory and calculation integrated chip;

The flexible memory integrated chip is used for completing data analysis according to the mode indicated by the first signal when the first signal is received.

For example, the second device may generate and issue the first signal. The first signal may be an electromagnetic wave signal. The purpose of the first signal may be energy supply or data analysis. The first signal is used for supplying energy, and the first signal is only in the form of electromagnetic waves and does not need to carry information. The first signal may further carry information related to the data analysis mode during data analysis, and the second device may modulate the information related to the data analysis mode onto the electromagnetic wave signal by means of modulation to obtain the first signal for data analysis.

For example, before the second device generates the first signal, a correspondence relationship between the attribute of the frequency band, the power, the time when the first signal is emitted, and the like of the first signal and the purpose of the first signal may be set. Exemplary arrangements may be found in the following for further description of the use of the first signal. The first device may determine the purpose of the received first signal according to the correspondence of the attribute and the purpose of the first signal. Based on the above, the second device can generate the first signal with the corresponding attribute according to the requirement to control the first device to work according to the requirement.

It should be understood by those skilled in the art that the use of the first signal may also be set by other attributes or other manners, as long as the first device is capable of determining the use of the first signal after receiving the first signal, and the manner of determining the use of the first signal is not limited by the embodiments of the present disclosure. For clarity of description, the correspondence between the attributes of the frequency band, the power, the time when the first signal is emitted, and the like of the first signal is set as an exemplary manner of determining the use of the first signal.

The first device may include a signal transceiver module, a power management module, and a flexible memory chip connected in pairs. Depending on the function of the module/chip and the connection between the modules/chips, the first device may be considered to comprise an energy path and a data path. The energy path can comprise a signal receiving and transmitting module and a power management module, and the data path can comprise a signal receiving and transmitting module and a flexible memory integrated chip. The flexible memory integrated chip is made of flexible materials, and has better ductility compared with a hard chip, and compared with a hard processor and a hard memory in the prior art, the flexible memory integrated chip has smaller volume under the premise of equal calculation force, and has stronger calculation force under the premise of the same volume, so that the volume and the power consumption of the first equipment can be reduced by using the flexible memory integrated chip.

Simultaneous wireless information and energy transfer (Simultaneous Wireless Information and Power Transfer, swift) is a wireless communication technology that enables simultaneous data and energy transfer. The first device of the embodiments of the present disclosure implements this technique through a signal transceiver module. The first signal may be received by a signal transceiver module of the first device. The signal transceiver module may include an antenna. The energy paths and the data paths may use independent antennas (see fig. 5 for an example) or may multiplex the same antennas (see fig. 6 for an example). Exemplary ways in which the signal transceiver module may implement simultaneous wireless information and energy transfer techniques may be found in the following description of the structure of the signal transceiver module.

The signal receiving and transmitting module can identify and determine the purpose of the first signal according to the frequency band, the power, the time of sending the first signal and other attributes of the first signal. When the first signal is used for energy supply, the first signal is transmitted to the power management module through the energy channel, and when the first signal is used for data analysis, the first signal is transmitted to the flexible memory integrated chip through the data channel.

Because the first signal is used for supplying energy without carrying information, the signal receiving and transmitting module can directly forward the first signal to the power management module after receiving the first signal and determining that the first signal is used for supplying energy. When the power management module receives the first signal, the first signal can be directly converted into electric energy for storage, and then the stored electric energy can be used for supplying power for the signal receiving and transmitting module and the flexible memory integrated chip. The structure of the power management module and exemplary ways of implementing power conversion and power supply can be seen from the relevant description of fig. 5.

Because the first signal carries information related to the data analysis mode during data analysis, the signal receiving and transmitting module can demodulate the first signal into a form that the flexible memory integrated chip can be directly used after receiving the first signal and determining that the first signal is used for data analysis, and then output the first signal to the flexible memory integrated chip. When the flexible memory integrated chip receives the first signal, the data analysis can be completed according to the data analysis mode indicated by the information carried by the first signal. For example, the purpose of the first signal is that the information carried in the data analysis may indicate which parameters are used for the data analysis. The analysis result may reflect a health condition of the wearing object of the first device. Examples of the information carried in the data analysis and examples of the manner of data analysis are given below for further description of the function of the flexible memory chip.

As shown in fig. 3, in one possible implementation, the first device further comprises a flexible sensor,

The flexible sensor is used for acquiring physiological data of a wearing object of the first equipment and transmitting the physiological data to the flexible memory integrated chip;

the flexible memory and calculation integrated chip is also used for storing physiological data;

Completing the data analysis in a manner indicated by the first signal, comprising:

And according to the mode indicated by the first signal, completing analysis of the physiological data and storing analysis results of the physiological data.

For example, the first device may also be provided with physiological data acquisition functionality, and may include a flexible sensor connected to the flexible memory chip and the power management module. The power management module also provides power to the flexible sensor. The flexible sensor may collect physiological data of a wearing object of the first device (e.g., user a). The first device may include a plurality of flexible sensors that collect physiological data of various types, such as pressure, respiration, temperature, motion sensors, etc., and the physiological data that may be collected may also include various types, such as heart rate, blood oxygen, blood pressure, stride frequency, sleep state, etc., to enable multi-directional monitoring of the user's health condition. The disclosed embodiments are not limited with respect to the specific number of flexible sensors and the specific type of physiological data that may be collected. The collected physiological data can be stored in a flexible memory integrated chip. When the flexible memory integrated chip finishes data analysis according to the mode of the first signal indication, the analyzed object can be physiological data, and the analysis result of the physiological data can be stored in the flexible memory integrated chip. If the first device is also provided with a display function, the analysis result can be displayed, so that the wearing object (such as a user A) can conveniently view the analysis result.

The flexible sensor can be made of flexible materials, and common flexible materials include flexible films (PET, PE, PVC), elastic materials (silica gel, latex), conductive materials (polyaniline, carbon nanotubes) and the like. The embodiments of the present disclosure are not limited as to what flexible materials are used in particular for flexible sensors.

The shape of the first device is more flexible when the first device uses a flexible sensor.

It will be appreciated by those skilled in the art that in practical applications, the first device may also use a hard sensor, and the embodiments of the present disclosure are not limited as to whether the sensor used by the first device is a flexible sensor.

An exemplary data analysis mode of the flexible memory chip of the embodiments of the present disclosure is described below.

In one possible implementation, a neural network model is deployed on a flexible memory integrated chip, and the data analysis is completed according to a first signal indication mode, including:

updating corresponding parameters in the neural network model by using parameters included in the first signal to obtain an updated neural network model;

and finishing data analysis by using the updated neural network model.

For example, a neural network model may be deployed on a flexible memory integrated chip of embodiments of the present disclosure, through which data analysis is accomplished. Parameters of the neural network model may be preset. The information carried by the first signal relating to the manner of data analysis may comprise parameters of a neural network model. The flexible memory integrated chip can store initial parameters of the neural network model. The parameter comprised by the first signal may be a parameter that needs to be updated. Examples of parameters may be found in the related description below. Therefore, the first device may complete the data analysis according to the manner indicated by the first signal, by updating the corresponding initial parameters in the neural network model using the parameters included in the first signal, to obtain an updated neural network model, and using the updated neural network model to complete the data analysis. At this time, the physiological data may be used as an input of the updated neural network model, and an output of the updated neural network model may be an analysis result of the physiological data.

The neural network model may be implemented based on the prior art and will not be described in detail herein. Those skilled in the art will understand that the embodiments of the present disclosure do not limit what neural network model is deployed on the flexible memory integrated chip, as long as the neural network model deployed on the flexible memory integrated chip can complete analysis of physiological data to determine health conditions.

In one possible implementation, the parameters include a generic parameter that is independent of the characteristics of the wearing object of the first device and/or a custom parameter that is related to the characteristics of the wearing object of the first device.

For example, the parameters may include general parameters such as an iterative accuracy index, a power consumption index, a weight, etc. of the neural network model that are independent of characteristics (such as age, gender, weight, etc.) of the wearing object (such as user a) of the first device. The parameters may also include customized parameters related to characteristics of the wearing object of the first device (e.g., user a), such as an age parameter, a gender parameter, a weight parameter, etc. The customized parameters may be trained from physiological data samples of wearing subjects of different characteristics (e.g., user a). In this way, the information which the first signal can carry about the data analysis is made more diverse and flexible.

In one example, the weights undergo multiple iterations as the neural network model analyzes the physiological data. As shown in fig. 4, the first device may further include a control module, where the control module is mainly configured to control a weight iteration process of the neural network model. After the flexible memory integrated chip starts data analysis, neural network models can be used for edge learning and reasoning. The obtained edge learning result (not shown) is output to the control module, the control module judges whether the weight needs to be iterated according to the edge learning result, and when the iteration weight is needed, a weight iteration instruction (not shown) is output to the flexible memory integrated chip. After the flexible memory integrated chip receives the weight iteration instruction, the next iteration can be performed on the weight of the neural network model.

By the method, the first equipment can adjust the acquisition, monitoring and early warning modes of physiological data according to the unique physical conditions and health requirements of different wearing objects (such as the user A) so as to realize a customized health monitoring scheme.

In one possible implementation, the signal transceiver module is further configured to receive the neural network model from the second device and to deploy onto the flexible memory chip.

For example, the neural network model may be pre-trained by the second device and output to the first device. After the signal receiving and transmitting module receives the neural network model, the neural network model can be directly deployed to the flexible memory integrated chip. The neural network model trained by the second device can be of various types, and in this case, when a user wants to change the neural network model deployed on the flexible memory integrated chip, the second device is used to train a new neural network model and output the new neural network model to the first device, so that the data analysis mode of the first device is more flexible.

In one possible implementation manner, the flexible memory integrated chip is further used for transmitting physiological data and/or analysis results of the physiological data to the signal transceiver module;

The signal transceiver module is further configured to transmit physiological data and/or an analysis result of the physiological data to the second device, where the analysis result of the physiological data is used to determine a parameter in the first signal that is output by the second device next and is used for data analysis.

For example, due to the limited memory space of the flexible memory chip, the first device may output physiological data and/or analysis results of the physiological data to the second device in order to save memory space. The flexible integrated memory chip may transmit the physiological data and/or the analysis result of the physiological data to the signal transceiver module, and the signal transceiver module modulates the physiological data and/or the analysis result of the physiological data onto a second signal in the form of electromagnetic waves and transmits the second signal to the second device.

The second device may obtain the physiological data and/or analysis results of the physiological data generated by the first device by demodulating the second signal. For the physiological data generated by the first device, the second device may perform analysis to obtain an analysis result of the physiological data, where an analysis manner may be the same as or different from a data analysis manner of the flexible memory chip, which is not limited in this disclosure. For the analysis result produced by the first device, the second device may perform an analysis to determine parameters in the first signal that are output next by the second device for use in data analysis.

In this way, parameters used by the neural network model can be updated with fluctuations in the health condition of the wearing object, so that the accuracy of analysis results of physiological data determined by using the neural network model is higher.

It should be understood by those skilled in the art that, for the analysis result generated by the first device, the second device may further perform analysis to determine the working state of the first device, the evolution condition of edge learning and reasoning of the neural network model on the flexible memory integrated chip, etc., and the application of the embodiment of the disclosure after the analysis result of the physiological data is output to the second device is not limited.

Further, the second device may send out electromagnetic wave signals of other purposes besides the first signal of energy supply or data analysis, for example, a third signal of controlling the working state (such as power on or power off) of the first device, so as to realize remote control of the working state of the first device. The embodiments of the present disclosure are not limited with respect to the specific use of the electromagnetic wave signal that the second device may transmit to the first device.

The first device and the second device may be located in the internet of things. Other devices which can communicate with the first device can be further included in the internet of things, so that a health management network is constructed.

An exemplary structure of the power management module is described below. Fig. 5 illustrates a schematic diagram of a structure of a power management module according to an embodiment of the present disclosure.

As shown in fig. 5, the power management module may include a matching network, a rectifier, an energy storage device, a low dropout linear regulator (low dropout regulator, LDO), and a power management control circuit. The matching network is used for performing impedance matching with an antenna in the signal receiving and transmitting a first signal from the signal receiving and transmitting module to the rectifier. The rectifier may employ a rectifying diode or a more complex circuit topology that may convert the first signal to dc power and output it to the energy storage device. The energy storage device may be a battery or a supercapacitor. The energy storage device may provide a voltage signal to the low dropout linear regulator LDO, and the low dropout linear regulator may boost the received voltage signal and provide the boosted voltage signal to other circuits in the first device to supply power to the other circuits in the first device. The power management control circuit is mainly used for monitoring and controlling the flow and storage of electric energy. The power management control circuit may include a maximum power point tracking controller for monitoring the energy conversion efficiency of the rectifier, and may protect the energy storage device from overcharge or overdischarge by monitoring the charge and discharge of the energy storage device.

The power management module provides power guarantees for the entire first device so that the first device can operate for a longer period of time. Meanwhile, the wireless charging mode also enables the application scene of the first device implanted in the body to be possible.

Those skilled in the art will appreciate that the power management module may be implemented based on the prior art, and that the embodiments of the present disclosure are not limited to the specific structure of the power management module.

Two exemplary configurations and three exemplary modes of operation of the signaling transceiver module are described below. Fig. 6 and 7 are schematic diagrams showing the structure of a signal transceiving module according to an embodiment of the present disclosure.

As shown in fig. 6, in one possible implementation, the signal transceiver module includes a first flexible antenna, a second flexible antenna and a data transceiver,

The first flexible antenna is used for determining that the purpose of the first signal is energy supply when receiving the first signal of the first frequency band, and transmitting the first signal to the power management module;

the second flexible antenna is used for determining that the purpose of the first signal is data analysis when the first signal of the second frequency band is received, and transmitting the first signal to the data transceiver;

the data transceiver is used for transmitting the first signal to the flexible memory integrated chip.

For example, the energy path and the data path of the first device may use different antennas. The configurable signal transceiver module includes a first flexible antenna, a second flexible antenna, and a data transceiver. The energy path may use a first flexible antenna and the data path may use a second flexible antenna and a data transceiver.

In this case, the first signal may be set to be an electromagnetic wave signal of a first frequency band when power is supplied, the first signal may be set to be an electromagnetic wave signal of a second frequency band when data is analyzed, and the first flexible antenna may receive the electromagnetic wave signal of the first frequency band and may not receive the electromagnetic wave signal of the second frequency band, and the second flexible antenna may receive the electromagnetic wave signal of the second frequency band and may not receive the electromagnetic wave signal of the first frequency band. The embodiment of the disclosure does not limit whether the first flexible antenna and the second flexible antenna also receive electromagnetic wave signals of other frequency bands.

In the energy path, when the first flexible antenna receives the first signal in the first frequency band, the first flexible antenna can determine that the first signal is used for supplying energy, and the first signal is transmitted to the power management module. In the data path, the second flexible antenna may determine that the first signal is for data analysis when it receives the first signal in the second frequency band, and transmit the first signal to the data transceiver.

The data transceiver may be implemented based on prior art. The data transceiver may include an operational amplifier, an analog-to-digital conversion circuit, etc. for amplifying, demodulating, analog-to-digital converting, etc. the first signal to obtain a digital first signal and transmitting the digital first signal to the flexible integrated memory chip, where the flexible integrated memory chip may directly use the received first signal.

Similarly, when the flexible memory integrated chip transmits the stored physiological data and/or the analysis result of the physiological data to the signal transceiver module, the flexible memory integrated chip can be received by a data transceiver in the signal transceiver module. The data transceiver may further include a digital-to-analog conversion circuit, etc. for modulating the stored physiological data and/or the analysis result of the physiological data onto a second signal in the form of electromagnetic waves after digital-to-analog conversion, and transmitting the second signal to the second flexible antenna. The second signal is transmitted by the second flexible antenna to the second device.

In this way, the energy path and the data path do not interfere with each other, and the first device can perform energy conversion and data analysis at the same time, thereby expanding the capability of the first device. And the antenna has simple structure when not multiplexing, does not need algorithm support, and is easy to realize.

The flexible antenna can be made of conductive fibers, graphene, transparent conductive films (PI, PET) and other materials. The use of a flexible antenna allows the first device to include more flexible material, facilitating the first device to change shape. It should be understood by those skilled in the art that, according to the application requirements, a hard antenna may be alternatively used, and the materials of the antenna in the signal transceiver module are not limited in the embodiments of the present disclosure.

The power multiplexing refers to respectively transmitting electromagnetic waves received by the same antenna to different modules according to a certain power proportion. The configurable signal transceiver module includes a third flexible antenna and a data transceiver. The energy path and the data path both use a third flexible antenna, and the data path also uses a data transceiver.

the data transceiver is used for transmitting a first signal to the flexible memory integrated chip.

For example, the energy and data paths of the first device may multiplex the same antennas and may take the form of time multiplexing. The time multiplexing refers to transmitting electromagnetic waves received by an antenna to different modules at different times according to a certain time proportion. The configurable signal transceiver module includes a fourth flexible antenna and a data transceiver. The energy path and the data path both use a fourth flexible antenna, and the data path also uses a data transceiver. In this case, the structure of the signal transceiver module may be as shown in fig. 7, and the third flexible antenna may be replaced with the fourth flexible antenna.

In this case, the second device may be arranged to emit a first signal for the purpose of energy supply during a first period of time and to emit a first signal for the purpose of data analysis during a second period of time. And a fourth flexible antenna is arranged to transmit the first signal received in the first time period to the power management module and transmit the first signal received in the second time period to the data transceiver.

In this case, when the fourth flexible antenna receives the first signal in the first period of time, the energy path is opened, and the first signal for supplying energy can be transmitted to the power management module for energy conversion. And when the fourth flexible antenna receives the first signal in the second time period, the data path is opened, and the first signal which is used for data analysis can be transmitted to the data transceiver.

By the mode, the working efficiency of the first equipment can be improved, the area of the signal receiving and transmitting module is smaller, the cost of the first equipment is reduced, and meanwhile, the mode of multiplexing the antenna is more flexible.
