Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
Fig. 1 is a schematic structural diagram of a motion detection apparatus based on NB communication technology in an embodiment of the present invention. The motion detection device 100 based on the NB communication technology is applied to a sports shoe, and includes: piezoelectric sensor 110, statistics unit 120, NB communication unit 130, and energy storage unit 140.
In an embodiment of the present invention, the piezoelectric sensor 110 is used for converting mechanical energy generated by a force applied during a movement into electrical energy and forming piezoelectric data.
The piezoelectric sensor 110 is a sensor made by using the piezoelectric effect generated by some dielectric medium after being stressed. The piezoelectric effect is a phenomenon in which electric charges are generated on the surface of some dielectrics due to a polarization phenomenon of internal electric charges when the dielectrics are deformed (including bending and stretching deformation) by an external force in a certain direction.
In this embodiment, the piezoelectric sensor 110 is used to obtain the electrical energy converted from the stress shape and store the electrical energy to provide the electrical energy to other units, so as to form an independent motion detection device without external power supply; on the other hand, piezoelectric data are formed by charge pulses obtained by each stress, accurate motion information can be obtained by counting, and for example, one charge pulse can represent one step.
In an embodiment of the invention, the statistical unit 120 is electrically connected to the piezoelectric sensor 110, and configured to receive the piezoelectric data, obtain motion information according to the statistical piezoelectric data, and send the motion information to the outside according to a certain sending condition.
It should be noted that the piezoelectric data directly obtained by the piezoelectric sensor 110 needs to be amplified to obtain the charge information.
In an embodiment of the present invention, the statistic unit 120 includes: a preamplifier 121 for amplifying the received piezoelectric data to acquire the motion information.
The preamplifier 121 is preferably a charge amplifier.
In an embodiment of the present invention, the statistic unit 120 further includes: one or more combinations of a counter, a timer, and a pressure gauge.
In this embodiment, the counter, the timer, and the voltage measuring device may be in a hardware form (e.g., a timing and counting functional end of an integrated chip), a software form (a related function in a code), or a combination form of software and hardware, such as a software form of the counter and the timer, a hardware form of the voltage measuring device, and the like.
It is easy to think that when the user is exercising (such as running), the pressure applied to the piezoelectric sensor 110 by touching the sole of the foot will deform, converting the mechanical energy into electrical energy and piezoelectric data. For example, the piezoelectric data, if presented as a waveform diagram, would be charge waveforms that rise and fall one by one with a certain spacing between each charge waveform. If the piezoelectric data obtained is normal, it can be visually understood that one charge waveform or charge pulse corresponds to one sole strike in motion.
In an embodiment of the invention, the statistic unit 120 is configured to obtain the motion information according to the statistical data, wherein the motion information includes one or more of the following:
a) and the counter acquires the motion step number in the motion information according to the occurrence frequency of each charge pulse in the piezoelectric data.
It will be readily appreciated that a charge waveform or charge pulse corresponds to one sole strike in a motion. Thus, the counter can obtain the number of motion steps as a function of the number of occurrences of each charge pulse in the piezoelectric data.
b) The timer obtains the motion type in the motion information according to the duration time of each charge pulse in the piezoelectric data.
For example, the pressure generated by different types of motion to the ground may be different, the duration of the generated pressure, or the duration of the generation of a charge pulse may be different. For example, walking is full sole touchdown, and the duration of the corresponding primary charge pulse is longer; jogging is full sole touchdown with a certain take-off or landing force, and the duration of a corresponding generated primary charge pulse is shorter than the duration of walking; while sprinting may only be a forefoot strike, with the corresponding generation of a charge pulse of the shortest duration.
In this embodiment, the motion types include: walking, jogging, running, etc.
Thus, the timer can capture the type of motion as a function of the duration of each charge pulse in the piezoelectric data.
c) The timer acquires the step frequency in the motion information according to the interval time of two adjacent charge pulses in the piezoelectric data; the step frequency is combined with the movement stride distance information or the movement path distance information of the corresponding user to obtain the movement speed.
In this embodiment, the interval time between two adjacent charge pulses in the piezoelectric data actually represents the frequency between steps or the time between two steps.
However, to calculate the speed also requires distance units. Therefore, the step frequency is combined with the movement stride distance information or the movement path distance information of the corresponding user to obtain the movement speed.
For example, signals such as the sex, the height, the weight and the like of the user are obtained in advance, the physical quality condition of the user can be simply estimated, and the stride example of the user under different exercise types (walking, jogging and running) can be further calculated. Based on the step frequency, the movement speed can be calculated by combining the step frequency.
And then, or the step frequency is externally sent to a server, and the server receiving background obtains the movement distance by obtaining the GPS positioning function of a user mobile terminal pipe (such as a mobile phone or an intelligent bracelet), so that the movement speed is further calculated.
d) And the pressure measurer obtains the energy consumption in the motion information according to the charge mean value or the charge peak value of each charge pulse in the piezoelectric data.
It should be noted that the emphasis of measuring the charge average value or the charge peak value of each charge pulse in the piezoelectric data is not on whether the measured charge value is accurate, but on performing corresponding operation according to the charge value to obtain the corresponding energy consumption (such as calorie consumption).
The pressure on the ground produced by different types of movements is different and the energy consumed is different. If walking is full sole touchdown, jogging is full sole touchdown with some take-off or landing force, while sprinting may be sole touchdown only.
Therefore, by measuring the charge value of each charge pulse in the piezoelectric data by means of the voltage measuring device and performing corresponding operation according to the charge value, as measured by experiment or experience, the amount of the charge generated by one step of walking is corresponding to the calories consumed by one step of walking, or the amount of the charge generated by one step of running/jogging is corresponding to the calories consumed by one step of running/jogging, so as to obtain the energy consumption in the exercise information.
In an embodiment of the present invention, the sending condition is a preset proportional threshold for any one of the exercise type, the step frequency, and the energy consumption, so that when a change in any one of the exercise type, the step frequency, and the energy consumption exceeds the preset proportional threshold, the sending condition of the statistical unit 120 is triggered, and the current exercise information is sent to the outside.
In this embodiment, the preset ratio threshold for any one of the exercise type, step frequency and energy consumption is preferably capable of distinguishing the exercise type (e.g. walking, jogging, running), so as to transmit the current exercise information when the exercise type changes. For example, the preset proportion threshold is 30%.
In the present embodiment, the advantage of transmitting the current motion information by recognizing that the motion type is changed is that the frequency of transmitting the current motion information is reduced, thereby saving the amount of power required to transmit the information. And when the motion type is changed, the requirement or habit of paying attention to the current motion information when the motion mode of the sporter is changed is sent.
In another embodiment of the present invention, the sending condition is preset with a sending time period for sending the current motion information to the outside according to the sending time period, or obtaining a communication connection with an external device.
For example, the exercise data is sent every 1 minute to obtain more objective historical exercise information or obtain accurate average data, and meet the requirement or habit of the user for observing the exercise data at any time.
In an embodiment of the present invention, the statistical Unit 120 may also be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; the Integrated Circuit may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, or a discrete hardware component.
In an embodiment of the present invention, the NB communication unit 130 is electrically connected to the statistics unit 120, and is configured to send the motion information to the outside.
The NB communication unit 130 is a cellular narrowband Internet of things (NB-IoT) based communication technology.
It has four major characteristics: the method has the advantages that firstly, the wide coverage is realized, the improved indoor coverage is provided, and under the same frequency band, the NB-IoT gains 20dB more than the existing network, which is equivalent to the capability of improving the coverage area by 100 times; secondly, the system has the capacity of supporting massive connections, one NB-IoT sector can support 10 ten thousand connections, and the system supports low delay sensitivity, ultralow equipment cost, low equipment power consumption and optimized network architecture; thirdly, the power consumption is lower, and the standby time of the NB-IoT terminal module can be as long as 10 years; fourth is the lower module cost, no more than $ 5 for a single successive module.
In a network environment where large bandwidth data does not need to be transmitted, the communication cost and the required power amount required by the NB communication method are much lower than those of the communication methods such as 4G, GSM and GPRS.
Since the motion detection apparatus 100 based on NB communication technology according to the present invention is independently powered, a unit that reduces power consumption as much as possible is required.
In this embodiment, since the motion detection apparatus 100 based on NB communication technology according to the present invention is independently powered, the NB communication unit 130 is further required to be in communication connection with an external device for receiving motion information.
In an embodiment of the invention, the energy storage unit 140 is electrically connected to each unit, and is configured to store electric energy obtained by converting mechanical energy generated by a force applied during movement of the piezoelectric sensor 110, and supply power to each unit.
Specifically, the energy storage unit 140 obtains and stores electric energy converted from mechanical energy generated by force applied during movement of the piezoelectric sensor 110, and provides power to each unit in real time.
It should be noted that the division of each unit of the above apparatus is only a logical division, and the actual implementation may be wholly or partially integrated into one physical entity, or may be physically separated. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the units can be realized in the form of calling software by the processing element, and part of the units can be realized in the form of hardware.
For example, the statistical unit 120 may be a processing element separately set up, or may be implemented by being integrated into a chip of the apparatus, or may be stored in a memory of the apparatus in the form of program code, and the statistical unit 120 may be called and executed by a processing element of the apparatus. The other units are implemented similarly. In addition, all or part of the units can be integrated together or can be independently realized. The processing element described herein may be an integrated circuit having signal processing capabilities. In implementation, the steps of the method or the units above may be implemented by hardware integrated logic circuits in a processor element or instructions in software.
For example, the above units may be one or more integrated circuits configured to implement the above methods, such as: one or more Application Specific Integrated Circuits (ASICs), or one or more microprocessors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs), among others. For another example, when one of the above units is implemented in the form of a Processing element scheduler code, the Processing element may be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. For another example, these units may be integrated together and implemented in the form of a system-on-a-chip (SOC).
