Description

Audio analysis method, system and storage medium based on neutron irradiation

technical field

The invention relates to the technical field of neutron radiation, in particular to an audio analysis method, system and storage medium based on neutron radiation.

Background technique

Single event effect (Single Event Effects, SEE): refers to the effect of a single particle with a certain energy (including heavy ions, protons, alpha particles, neutrons, etc.) Single event lockout, single event hard error, single event functional interruption, single event burnout, single event gate breakdown, single event transient pulse, etc.

In the harsh natural radiation environment, the single event effects (Single Event Effects, SEE) produced by high-energy protons, alpha particles and heavy ions in the space electronics system are seriously threatened by galactic cosmic rays, solar cosmic rays and geomagnetic field capture belts. The safe operation of spacecraft is a well-known fact. In addition, the single event effect caused by atmospheric neutrons in avionics systems, ground base stations, supercomputers and other equipment has attracted more and more attention from the industry, posing a threat to the safe and reliable operation of equipment. Radiation particles in nuclear power plants, nuclear explosions and other environments can also cause single event effects in electronic equipment.

It can be seen that the single event effect is one of the main reliability problems faced by electronic components in the radiation environment, and with the development of Moore's Law, the feature size of commercial or civilian semiconductor chips and devices is gradually reduced, including motherboard chips for smartphones , so that in the atmospheric environment, it is still possible to cause errors in devices, chips and even systems due to the irradiation of particles (mostly atmospheric neutrons and alpha particles). Nowadays, people are accustomed to using smartphones to listen to music, watch movies, and even conduct sensitive financial and property transactions.

In summary, the purpose of the present invention is to propose an analysis method for audio errors generated by smart terminals (such as mobile phones) in the case of neutron irradiation. This method analyzes the types of audio errors generated by smartphones under neutron irradiation, the characterization method, and some characteristics of various errors, etc., and expands the neutron irradiation effect from the study of ordinary integrated circuits or devices to For the research on chips in smart phones, provide research directions and basic data for the research on the anti-neutron radiation hardening of smart phone chips.

Taking the mobile phone as an example, describe in detail the specific implementation steps of an audio analysis method based on neutron irradiation in the present invention:

S1. Before the experiment, use the music playback function and screen recording function in the mobile phone to pre-record four sections of audio and video with the same length of time, two of which (recorded as the control group) are transferred to the PC (that is, the background analysis terminal), and the other two ( Recorded as storage group) stored in the mobile phone storage area;

S2. Turn on the neutron beam, record the turn-on time and the fluence rate of the neutron, and use it to analyze the neutron dose and the error relationship after the experiment;

S3. Control the smart phone to record several sections of audio and video with the same duration as the control group and the storage group (recorded as the recording group). It should be ensured that the segments recorded each time are the same file, and the beginning of the recorded file is the same;

S4. After collecting enough samples, turn off the neutron beam, record the closing time, and transfer all the audio and video (including two sections of the storage group) stored in the smart phone to the PC for analysis;

The analysis of audio errors in the present invention is divided into two aspects, which are respectively audio waveform analysis and audio hexadecimal data analysis.

Among them, the analysis of the audio waveform is to transform hearing into a more intuitive and visible vision, which can directly observe the changes of the audio waveform irradiated by neutrons;

The analysis of audio hexadecimal data is to deepen it from the macro-visible level to the invisible data level, so that deeper errors that cannot be seen in waveform analysis can be observed, and then the impact of neutron irradiation on the most The effect of the underlying data.

These two analysis methods are combined to comprehensively evaluate the impact of neutron radiation on smartphone audio, from macro-visible error analysis to underlying data error analysis.

Specifically, the main analysis steps of audio waveform analysis are as follows:

1) Extract all the audio and video in the PC into an audio format with the suffix .avi, and import it into the audio editing software named "Audacity". In this software, all the audio is intercepted into the beginning, end, and duration For a consistent file, set it to display in units of dB, and at the same time zoom in on the waveform on the time axis until each sampling point can be observed, and each sampling point is approximately equal to 0.02 milliseconds;

Among them, this embodiment removes the beginning and end of the audio and video, and only retains the middle part for analysis, which can reduce the impact of errors caused by manual clicks to start and click to end, and further improve the accuracy of the analysis results.

2) Open the two files in the control group on the same interface, and observe the waveforms of the two files. It can be seen that the waveforms of the two files are exactly the same, as shown in Figure 2, it can be proved that in the case of no neutron irradiation, The waveforms obtained from music playback and recording can be used as a control group for experimental analysis, that is to say, if the files that have been irradiated by neutrons are different from the control group files, it should be caused by errors caused by neutron effects;

3) Compare the audio waveforms of the two files in the storage group with the control group in turn. If any differences are found, it can be proved that neutron radiation has produced a neutron effect on the storage area of the smartphone; as shown in Figure 3, it can be seen Compared with the control group, the audio waveform of the storage group has a smaller overall waveform amplitude, and the human ear can distinguish that the overall volume has become smaller. This is one of the types of errors produced by the neutron effect on the audio waveform;

4) Compare the audio waveforms of the files in the recording group with those in the control group in turn. If any differences are found, it can be proved that neutron radiation has produced a neutron effect on the running memory area of the smart phone management; as shown in Figure 4 and Figure 5 As shown in Figure 6, it can be seen that the audio waveform of the recording group has three errors compared with the control group:

a) The waveform moves backward as a whole (Figure 4). This error has the most occurrences and duration, and the longest duration is about 40 milliseconds;

b) The waveform moves forward as a whole (Figure 5). Compared with error a, this error has fewer occurrences and less duration, and the longest duration is about 10 milliseconds;

c) The amplitude of the waveform varies locally (Figure 6), and this error occurs frequently.

The main analysis steps of audio hexadecimal data analysis are as follows:

This part analyzes the hexadecimal data of audio files that are invisible to the macro:

1) All the audio and video files intercepted into the beginning, end and time length in the step 1) of the audio waveform analysis are converted into hexadecimal data, and stored in a .txt file with the same name;

2) Import the hexadecimal data of the two files in the control group into the comparison program, and the comparison program will intelligently analyze and mark the similarities and differences of all the data. It can be seen that the two files in the control group are completely consistent. As shown in Figure 7, it proves that in the case of no neutron irradiation, the audio hexadecimal data can be used as a control group for experimental analysis, that is to say, if the files that have been subjected to neutron irradiation are different from the control group files, they should be due to errors caused by neutron effects;

3) Compare the hexadecimal data of the two files in the storage group with the control group in turn. If any differences are found, it can be proved that neutron radiation has produced a neutron effect on the storage area of the smartphone; as shown in Figure 8 and Figure 8. 9. It can be seen that the hexadecimal data of the storage group has two types of errors compared with the control group:

a) Data random errors (as shown in Figure 8);

b) There is a difference between 0x55 and 0xAA in data comparison (as shown in Figure 9), where the storage group data is 0xAA, and the control group data is 0x55.

4) Compare the hexadecimal data between the files of the recording group and the control group in turn. If any differences are found, it can be proved that the neutron irradiation has a neutron effect on the running memory area of the smart phone management; as shown in Figure 10, Figure 11, Figure 12 and Figure 13, it can be seen that the hexadecimal data of the recording group has four types of errors compared with the control group;

a) several bits of data are moved forward (as shown in Figure 10);

b) A number of bits of data are shifted backward (as shown in Figure 11);

c) Data random errors (as shown in Figure 12);

d) There is a difference between 0x55 and 0xAA in the data comparison (as shown in Figure 13), where the recording group data is 0xAA, and the control group data is 0x55.

Perform the analysis of the above two methods on the same audio file in turn. The audio waveform analysis is an intuitive and comprehensive evaluation of the errors caused by neutron irradiation, while the audio hexadecimal data analysis is a partial in-depth analysis of the errors caused by neutron irradiation. evaluation. The two analysis methods are combined to comprehensively evaluate the impact of neutron radiation on smartphone audio.

To sum up, the method for analyzing audio errors of smart phones under neutron irradiation proposed by the present invention combines macroscopically visible audio waveform analysis with macroscopically invisible audio hexadecimal data analysis to more comprehensively center The analysis of neutron radiation effect is a relatively innovative method to analyze the audio errors of smartphones caused by neutron radiation. Through experimental examples, the audio errors under neutron radiation are classified and summarized, and then the neutron radiation is revealed. This will provide basic data and research directions for the next step in the research on neutron radiation resistance of mobile phone chips.
