The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a schematic diagram of a system for testing an intelligent electrocardiograph device in an embodiment of the present application, where, as shown in fig. 1, the system for testing an intelligent electrocardiograph device includes a signal source 11 and an intelligent electrocardiograph device 12, a signal transmitting end of the signal source 11 is connected with a signal receiving end of the intelligent electrocardiograph device 12, the signal source 11 transmits a signal to the intelligent electrocardiograph device 12, and the intelligent electrocardiograph device 12 receives the signal transmitted by the signal source 11 and performs a test.
Here, the smart electrocardiograph device means a smart device that can monitor and display an electrocardiogram of a human body, and for example, may be a smart wearable watch, a smart wearable bracelet, or the like; the shape of the intelligent electrocardiograph is not limited by the embodiment of the application.
Wherein the signal source may represent an object that generates and emits a signal, i.e. the source of the signal; the signal source may be a function signal generator, wherein the function signal generator may output certain periodic time function waveforms, such as sine waves, square waves, etc.; here, the type of the signal source output waveform may be set based on the case of actually testing the intelligent electrocardiograph, and the embodiment of the present application is not limited.
In the embodiment of the application, the signal source mainly provides the required input signal for the intelligent electrocardio equipment, the input signal is known, and the intelligent electrocardio equipment achieves the purpose of testing the intelligent electrocardio equipment by measuring the parameters related to the input signal.
Embodiments of the present application provide a method for testing an intelligent electrocardiograph device, which may be applied to an intelligent electrocardiograph device or other electronic devices, such as a handheld or laptop device, a microprocessor-based system, a computer system, and the like, and fig. 2 is a flowchart of a method for testing an intelligent electrocardiograph device, as shown in fig. 2, and the method includes the following steps:
s201, receiving an input signal sent by a signal source, where the input signal represents a signal with a fixed parameter, and the fixed parameter includes at least one of the following: fixed frequency, fixed amplitude.
In the embodiment of the application, the frequency is the number of times of completing periodic change in unit time, and is the quantity for describing the frequent degree of periodic movement, and is generally indicated by a symbol F; the amplitude is the maximum value that the physical quantity of vibration can reach, and is the physical quantity that represents the range and intensity of vibration, and is generally indicated by the symbol a.
In the embodiment of the present application, the fixed frequency represents a constant frequency of the input signal, and the fixed amplitude represents a constant amplitude of the input signal.
The input signal may be a sine wave with a frequency of 10HZ, a sine wave with an amplitude of 3MV, or a sine wave with a frequency of 10HZ and an amplitude of 3MV, for example.
For example, the smart electrocardiograph device may receive a sine wave with a frequency of 10HZ transmitted by the signal source, may receive a sine wave with an amplitude of 3MV transmitted by the signal source, and may also receive a sine wave with a frequency of 10HZ and an amplitude of 3MV transmitted by the signal source.
In one embodiment, the input signal may represent a signal within a range of frequencies and/or amplitudes; for example, the input signal may represent a signal having a frequency of less than 50HZ or greater than 60HZ, and the input signal may also represent a signal having an amplitude greater than 0 MV.
Here, the frequency of the ac electric signal is usually 50HZ or more and 60HZ or less, and when the input signal frequency is 50HZ or more and 60HZ or less, the frequency of the ac electric signal may be considered to be generated due to a short-circuit failure in the internal circuit of the intelligent electrocardiograph device when the intelligent electrocardiograph device receives the input signal of the frequency. Therefore, in the embodiment of the application, under the condition that the input signal represents the signal with the frequency smaller than 50HZ or larger than 60HZ, the situation that the intelligent electrocardio equipment misjudges the input signal as the intelligent electrocardio equipment fails can be effectively avoided, and further, the accuracy of testing the intelligent electrocardio equipment is improved.
S202, acquiring test parameters of an input signal, and judging whether the test parameters are in a set range or not to obtain a first judgment result; the test parameters represent the frequency and/or amplitude of the input signal sampled.
Here, sampling may be a process of converting a continuous quantity of the time domain or the spatial domain into a discrete quantity; when the input signal is a signal with fixed frequency and/or fixed amplitude, the intelligent electrocardio equipment acquires the input signal and samples the input signal, so that the frequency and/or the amplitude corresponding to each sampling point can be obtained; wherein the frequency and/or amplitude corresponding to each sampling point may represent a test parameter of the input signal.
In one embodiment, the frequency or amplitude of the input signal may be changed due to some interference signals during the transmission process, that is, the fixed frequency or fixed amplitude of the input signal sent by the signal source may be different from the frequency or amplitude of the input signal sampled by the smart electrocardiograph.
For example, in the case where the fixed frequency of the input signal sent by the signal source is 10HZ and the fixed amplitude is 3MV, the input signal acquired by the smart electrocardiograph device may be a signal having a frequency of 11HZ and an amplitude of 3 MV.
In the embodiment of the application, the first judgment result is obtained by judging whether the frequency or the amplitude corresponding to each sampling point of the discrete analog signal is in the set range.
In one embodiment, the upper limit of the set range is the product of the fixed parameter and a first ratio, the lower limit of the set range is the product of the fixed parameter and a second ratio, the ratio of the first ratio ranges from 105% to 120%, and the ratio of the second ratio ranges from 80% to 95%.
Illustratively, in the case where the fixed frequency of the input signal is 10HZ, the upper limit of the set range is 10.5HZ to 12HZ, and the lower limit of the set range is 8HZ to 9.5HZ. If the frequency corresponding to the sampling point in the test parameter is 50HZ, the test parameter is not in the set range, and if the frequency corresponding to the sampling point in the test parameter is 11HZ, the test parameter is in the set range.
For example, in the case where the fixed amplitude of the input signal is 10MV, the upper limit of the set range is 10.5MV to 12MV, and the lower limit of the set range is 8MV to 9.5MV. If the amplitude corresponding to the sampling point in the test parameter is 5MV, the test parameter is not in the set range, and if the amplitude corresponding to the sampling point in the test parameter is 9MV, the test parameter is in the set range.
For example, in the case where the fixed frequency of the input signal is 10HZ and the fixed amplitude is 10MV, the upper limit of the set range of the fixed frequency is 10.5HZ to 12HZ and the lower limit of the set range of the fixed amplitude is 8HZ to 9.5HZ. If the frequency corresponding to the sampling point in the test parameter is 50HZ and the amplitude is 5MV, the test parameter is not in the set range, and if the frequency corresponding to the sampling point in the test parameter is 11HZ and the amplitude is 9MV, the test parameter is in the set range.
As can be seen, there are two cases of the first determination result: one is when the test parameter is not in the set range, and the other is when the test parameter is in the set range.
S203, determining the stability of the electrocardiograph performance of the intelligent electrocardiograph equipment according to the first judging result.
In the embodiment of the application, the intelligent electrocardiograph device can determine the stability of electrocardiograph performance of the intelligent electrocardiograph device according to the judging result of whether the test parameter is in the set range.
In one embodiment, the intelligent electrocardiograph device may record, respectively, that the first determination result is that the test parameter is in the set range and that the first determination result is that the test parameter is not in the set range.
In the embodiment of the application, the intelligent electrocardio equipment determines the stability of the electrocardio performance of the intelligent electrocardio equipment by judging whether the test parameters of the input signals are in a set range, and can improve the test precision of the intelligent electrocardio equipment.
In an embodiment, the determining, according to the first determination result, stability of electrocardiograph performance of the intelligent electrocardiograph device may include: determining the times of the test parameters in a set range in a sampling period according to the first judging result; judging whether the times reach a first set value or not to obtain a second judging result; and determining the stability of the electrocardiograph performance of the intelligent electrocardiograph equipment according to the second judging result.
In the embodiment of the application, the number of times that the test parameter is in the set range in one sampling period can be determined, whether the number of times is larger than the first set value is judged, a corresponding judgment result is obtained, and the stability of the electrocardiograph performance of the intelligent electrocardiograph device is determined according to the judgment result.
Here, the first setting value may be set according to an actual situation of testing the intelligent electrocardiograph, for example, in a case where the total sampling number in the sampling period is 10 times, the first setting value may be 8 times; further, the corresponding judgment results are two kinds: the number of times that the test parameter is in the set range in the sampling period is greater than 8 times or the number of times that the test parameter is in the set range in the sampling period is less than or equal to 8 times.
Illustratively, in the case where the fixed frequency is 10HZ, the upper limit of the set range is 10.5HZ to 12HZ, and the lower limit of the set range is 8HZ to 9.5HZ. If the frequency obtained by 10 times of sampling in the test parameters is 50HZ, 11HZ, 9HZ, 12HZ, 10HZ, 8HZ, 10HZ, 11HZ, 9HZ and 8HZ respectively; it can be seen that the frequencies obtained by the other samples are within the set range except for 50HZ, i.e. there are 9 samples within the set range, which is 8 times greater than the first set point.
In an embodiment, the determining, according to the first determination result, stability of electrocardiograph performance of the intelligent electrocardiograph device may include: determining the frequency proportion of the test parameter in a set range in a sampling period according to the first judging result; judging whether the frequency proportion reaches a set proportion value or not to obtain a third judging result; and determining the stability of the electrocardiograph performance of the intelligent electrocardiograph equipment according to the third judging result.
In the embodiment of the application, the frequency proportion of the test parameter in the set range in one sampling period can be determined, whether the frequency proportion is larger than the set proportion value is judged, a corresponding judgment result is obtained, and the stability of the electrocardiograph performance of the intelligent electrocardiograph device is determined according to the judgment result.
Here, the set proportion value may be set according to the actual situation of testing the intelligent electrocardiograph, for example, in the case where the total sampling number in the sampling period is 10 times, the set proportion value may be 80%; further, the corresponding judgment results are two kinds: the set proportion value of the test parameter in the set range in the sampling period is more than 80% or the set proportion value of the test parameter in the set range in the sampling period is less than or equal to 80%.
Illustratively, in the case where the fixed frequency is 10HZ, the upper limit of the set range is 10.5HZ to 12HZ, and the lower limit of the set range is 8HZ to 9.5HZ. If the frequency obtained by 10 times of sampling in the test parameters is 50HZ, 11HZ, 9HZ, 12HZ, 10HZ, 8HZ, 10HZ, 11HZ, 9HZ and 8HZ respectively; it can be seen that the frequencies obtained by sampling are all within the set range except for 50HZ, i.e. the proportion of times the test parameter is within the set range is 90%, which is greater than the set proportion value of 80%.
In an embodiment, the determining the stability of the electrocardiograph performance of the intelligent electrocardiograph device according to the second determination result or the third determination result may include: under the condition that the second judging result or the third judging result is yes, determining that the stability of the electrocardiograph performance of the intelligent electrocardiograph device meets a preset stability requirement; and under the condition that the second judging result or the third judging result is negative, the stability of the electrocardiograph performance of the intelligent electrocardiograph device is not satisfied with the preset stability requirement.
In the embodiment of the application, if the second judgment result indicates that the number of times reaches the first set value; or the third judgment result indicates that the frequency proportion reaches a set proportion value, so that the stability of the electrocardiograph performance of the intelligent electrocardiograph device meets the preset stability requirement.
In the embodiment of the present application, if the second judgment result indicates that the number of times does not reach the first set value; or the third judgment result indicates that the frequency proportion does not reach the set proportion value, which indicates that the stability of the electrocardiograph performance of the intelligent electrocardiograph device does not meet the preset stability requirement.
For example, in the case of sampling an input signal and the number of sampling points in a sampling period is 10, test parameters of 10 sampling points are respectively determined, for example: the judgment result shows that 8 test parameters are in the set range, and the other 2 test parameters are not in the set range; the intelligent electrocardiograph device records the judgment result.
Because the stability of the electrocardiograph performance can directly influence the monitoring function of the intelligent electrocardiograph equipment, the performance of the intelligent electrocardiograph equipment is extremely important to test; the higher the stability of the electrocardiograph performance, the more reliable the electrocardiograph data provided by the intelligent electrocardiograph device is, and further, the higher the reference value of the intelligent electrocardiograph device is.
The embodiment of the application provides a method for testing intelligent electrocardio equipment, which comprises the following steps: receiving an input signal transmitted by a signal source, the input signal representing a signal having a fixed parameter, the fixed parameter comprising at least one of: fixed frequency, fixed amplitude; acquiring test parameters of an input signal, and judging whether the test parameters are in a set range or not to obtain a first judgment result; the test parameters represent the frequency and/or amplitude obtained by sampling the input signal; determining the stability of the electrocardiograph performance of the intelligent electrocardiograph equipment according to the first judging result; thus, the embodiment of the application can test the intelligent electrocardiograph equipment by only providing the input signal with the fixed parameter by the signal source, namely, the intelligent electrocardiograph equipment can be tested without generating the electric signal by relying on the human electrocardiograph data, and the testing method is simple and convenient and can reduce the complexity of testing the intelligent electrocardiograph equipment; further, the intelligent electrocardiograph device determines the stability of electrocardiograph performance of the intelligent electrocardiograph device by judging whether the test parameters of the input signals are in a set range, so that the test precision of the intelligent electrocardiograph device can be improved;
in one embodiment, the steps S201 to S203 may be implemented by the smart electrocardiograph, that is, the smart electrocardiograph may implement a function of testing electrocardiographic performance. Therefore, in the case, the intelligent electrocardio equipment does not need an external processor device to analyze and process the electric signals; further, since the processor devices are typically floor standing, the size is typically 100 x 85cm; the device for testing the intelligent electrocardiograph is actually a small machine table which can be placed on a table top, and the size of the device is generally 40 x 60cm; thus, the device for testing the intelligent electrocardiograph is more miniaturized.
On the basis of the method for testing the intelligent electrocardiograph device, which is provided by the embodiment, the embodiment of the application provides a device for testing the intelligent electrocardiograph device.
