Description

Technical Field

[0001] The present invention relates to the technical field of electrocardiogram data storage, and in particular to an electrocardiogram file recording method, device, equipment and medium supporting power-off continuity. Background Art

[0002] The dynamic electrocardiogram system consists of an electrocardiogram recording box and a processing end, which is used to continuously record and analyze the changes in the electrocardiogram of the heart during human activity and rest over a period of time. The electrocardiogram recording box collects and stores the user's electrocardiogram data over a period of time through electrodes placed on the user's body surface. After the electrocardiogram data collection is completed, the electrocardiogram data is transmitted to the processing end through SD (Secure Digital Memory Card) card and USB (Universal Serial Bus) data line transmission, etc. The processing end reads and automatically analyzes the electrocardiogram data to complete the drawing of the electrocardiogram.

[0003] Since the dynamic electrocardiogram system requires the user to wear the electrocardiogram recording box in real time when using the electrocardiogram recording box to collect electrocardiogram data, it is possible that the electrocardiogram recording box battery may have poor contact for a short time due to the user's movement, resulting in abnormal power failure. In addition, in order to facilitate user use, the electrocardiogram recording box is generally powered by alkaline batteries that are easy to replace. At this time, if the battery is low and needs to be replaced during the electrocardiogram data collection, it will also cause abnormal power failure. After the above-mentioned abnormal power failure occurs, the electrocardiogram recording box will terminate the collection of this electrocardiogram data, resulting in data loss in the electrocardiogram data collected within a period of time, making the final electrocardiogram data incomplete. When the processing end processes the electrocardiogram data with data loss, it is very easy to cause errors in the drawn electrocardiogram, or even make it impossible to draw it at all.

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] The dynamic electrocardiogram system consists of two parts: an electrocardiogram recording box and a processing end. It is used to continuously record and analyze the changes in the electrocardiogram of the heart during human activity and rest over a period of time. The electrocardiogram recording box collects and stores the user's electrocardiogram data over a period of time through electrodes placed on the user's body surface. After the electrocardiogram data collection is completed, the electrocardiogram data is transmitted to the processing end through SD cards and USB data cables. The processing end reads and automatically analyzes the electrocardiogram data to complete the drawing of the electrocardiogram.

[0046] Since the dynamic electrocardiogram system requires the user to wear the electrocardiogram recording box in real time when using the electrocardiogram recording box to collect electrocardiogram data, it is possible that the electrocardiogram recording box battery may have poor contact for a short time due to the user's movement, resulting in abnormal power failure. In addition, in order to facilitate user use, the electrocardiogram recording box is generally powered by alkaline batteries that are easy to replace. At this time, if the battery is low and needs to be replaced during the electrocardiogram data collection, it will also cause abnormal power failure. After the above-mentioned abnormal power failure occurs, the electrocardiogram recording box will terminate the collection of this electrocardiogram data, resulting in data loss in the electrocardiogram data collected within a period of time, making the final electrocardiogram data incomplete. When the processing end processes the electrocardiogram data with data loss, it is very easy to cause errors in the drawn electrocardiogram, or even make it impossible to draw it at all.

[0047] To this end, the present application provides an ECG file recording solution that supports power-off persistence, which can record dynamic ECG data during the abnormal power outage process during the power-on process after the abnormal power outage, so as to obtain a complete ECG file.

[0048] Reference Figure 1 As shown, the embodiment of the present application discloses a method for recording an electrocardiogram file that supports power-off persistence, including:

[0049] Step S11: When the dynamic electrocardiogram detector is powered on again after power failure, the current power-on real-time time is obtained, and the sector number corresponding to the last valid dynamic electrocardiogram data storage sector and the power-on real-time time corresponding to the start of writing the valid dynamic electrocardiogram data are determined, and the corresponding last sector number and target power-on real-time time are obtained.

[0050] In this embodiment, when the Holter monitor is powered on again after power failure, the current power-on real-time time is recorded and the sector number corresponding to the last valid Holter data storage sector is obtained from the non-volatile storage area, and the sector number is determined as the last sector number, that is, the last valid sector number. In this way, the valid Holter data storage sector corresponding to the valid Holter data storage when the Holter monitor is powered off can be determined by the last sector number to obtain the last valid Holter data storage sector. The power-on real-time time corresponding to the start of writing the valid Holter data in the last valid Holter data storage sector is obtained to obtain the target power-on real-time time.

[0051] Step S12: determining the current sector number corresponding to the current sector for storing the currently acquired dynamic electrocardiogram data based on the sector number sequence and the previous sector number.

[0052] In this embodiment, the current sector number corresponding to the current sector for storing the currently collected dynamic electrocardiogram data is determined from the non-volatile storage area according to the sector numbering sequence and the previous sector number. It can be understood that the current sector number is determined from the non-volatile storage area according to the sector numbering sequence and the previous sector number, that is, all sectors are sorted according to the numbering sequence, and when the power is turned off and then on again, the current sector number corresponding to the current sector recording the valid dynamic electrocardiogram data after the current power-on is determined according to the numbering sequence and the previous sector number corresponding to the sector recording the valid dynamic electrocardiogram data before the power-off.

[0053] Step S13: Determine the duration of valid dynamic ECG data stored when the dynamic electrocardiogram detector is powered off according to the sampling time corresponding to the sector and the previous sector number, and determine the power-off duration of the last valid dynamic ECG data storage sector according to the target power-on real-time time, the current power-on real-time time and the valid dynamic ECG data duration to obtain the target power-off duration.

[0054] In this embodiment, the effective dynamic electrocardiogram data duration stored when the dynamic electrocardiogram detector is powered off is determined according to the sampling time corresponding to the sector and the previous sector number. Specifically, the sampling time corresponding to each sector is set by the user or preset by the system of the dynamic electrocardiogram detector. Then, the number of sectors in which the electrocardiogram data has been recorded is obtained by using the sector number information contained in the previous sector number, and then the sampling time is multiplied by the number of sectors to obtain the first storage data duration when the power is off, that is, the effective dynamic electrocardiogram data duration. Then, based on the target power-on real-time time and the current power-on real-time time, the power-on duration of the last effective dynamic electrocardiogram data storage sector is determined to obtain the target power-on duration; the target power-on duration and the effective dynamic electrocardiogram data duration are used to determine the power-off duration of the last effective dynamic electrocardiogram data storage sector to obtain the target power-off duration. It can be understood that the target power-on duration of the last effective dynamic electrocardiogram data storage sector is determined by subtracting the target power-on real-time time from the current power-on real-time time. Then, the target power-on duration is subtracted from the valid dynamic ECG data duration to obtain the power-off duration of the last valid dynamic ECG data storage sector, that is, the target power-off duration.

[0055] Reference Figure 2As shown, the sampling time required to write each sector data is preset by the system or set by the user. It should be noted that the power-off event includes: the power-off process and the power-on process. When the dynamic ECG data begins to be stored, the clock chip starts timing and records the real-time time T0 at the same time, which is the target power-on real-time time. When the first power-off event occurs, the clock chip continues to time. At this time, the clock chip obtains a signal and records the first timing T1, which is the current power-on real-time time. The first power-on duration ΔT1=T1-T0 can be calculated, which is the target power-on duration ΔT1. Similarly, the second power-on duration ΔT2=T2-T1 can be obtained. The first power-on duration ΔT1 consists of two durations, namely the first data storage duration H1, which is the effective dynamic ECG data duration H1 and the first power-off duration D1, which is the target power-off duration. Therefore, ΔT1=H1+D1. The sector number (C X , S Y ) can be used to know the number of sectors that have recorded ECG data. By multiplying this number by the sampling time required for each sector data, the first data storage duration H1 when power failure occurs can be calculated. The first power failure duration D1 can be calculated by D1 = ΔT1-H1. According to the above method, multiple ΔT i , H i , D i From this, we can know the actual total recording time ΣΔT i =H+D, where H=H1+...+H N+1 , D=D1+...+D N .like Figure 2 As shown, the first power-off duration = first power-on time - start storage time - first data storage duration; the second power-off duration = second power-on time - first power-on time - second data storage duration; the nth power-off duration = nth power-on time - nth - 1st power-on time - nth data storage duration; the last data storage duration = total data size converted to duration - each data storage duration; total recording duration = sum of each data storage duration + sum of each power-off duration; actual recording total duration = sum of each data storage duration. Among them, the duration of each data storage duration can be calculated by converting the data sampling rate and the size of each data storage duration.

[0056] When a power failure occurs, the writing of the Holter file is interrupted. After power is restored, the number of the sector last written before the power failure is read from the non-volatile storage area, and the file writing continues from the next sector of the sector. For example, the read sector number is (C5, S 10 ), then the next sector number is (C5, S 11), when the power is turned on again, data writing will continue from this sector. The total recording time of the ECG file can be preset in advance or set by the user. If N power failures occur during the recording process, N+1 storage data durations H and N power failure durations D can be obtained.

[0057] Step S14: using the preset ECG waveform data to fill the disk space corresponding to the target power-off duration in the last valid dynamic ECG data storage sector, so as to obtain a complete ECG data recording file.

[0058] In this embodiment, the preset ECG waveform data is written to the disk space corresponding to the target power-off duration in the last valid dynamic ECG data storage sector. When the dynamic ECG data recording event is detected to be over, the sector offset corresponding to the target power-off duration is converted, and the sector offset is performed according to the sector offset to fill the data gap of the dynamic ECG data of the actual duration, obtain the target ECG data, and construct a complete ECG data recording file according to the target ECG data. It can be understood that due to the power-off event during the acquisition process, the effective acquisition duration, that is, the value of the storage data duration H is less than the preset total recording duration of the ECG file. In order to ensure the accuracy of the data duration, the processing end will supplement the storage data duration H when entering data to make it equal to the preset total recording duration of the ECG file. Specifically, the processing end can read the power-on real-time time and the last valid sector number, calculate the power-off time period duration in combination with the starting storage real-time time recorded when starting storage, convert and calculate the sector offset corresponding to the power-off duration, perform sector offset, and restore the actual duration data.

[0059] When the processing end parses the ECG data and power-off information, it first obtains the position of each time node (the time point when recording starts, the time point when the Nth power-on is turned on), calculates the position of the Nth power-off time point, and then calculates the duration of each segment, that is, the duration of each storage segment data and the duration of each power-off segment, and finally supplements the power-off duration data at each power-off time node, thereby obtaining the complete data after recovery. The power-off segment duration data can be uniformly supplemented with agreed characteristic waveform data, such as: triangular wave data of a specific frequency.

[0060] When the recording ends, the file end mark is written, specifically: write the file size, change the file size attribute of the specified file root directory, etc., and then record the actual stored file size to prevent the file from being too large. Specifically, when the dynamic ECG data collection is completed, the dynamic ECG file writing ends, and the end mark is written to the last sector (C x’ , S Y’ ), the entire ECG data recording file is written. When the file is written, the entire ECG data recording file occupies sectors (C1, S1) to (C x’ , SY’ ), the sectors that have been assigned sector numbers but not occupied will be released after the file is written to reduce the file size. It can be seen that updating the file size attribute according to the recorded continuous sector size when the file ends storage not only effectively reduces the storage space occupied by the file, but also saves time for the processing end to process data in units of files, which has practical significance.

[0061] It can be seen that the present application discloses an ECG file recording method that supports power-off persistence, including: when the dynamic electrocardiogram detector is powered on again after power failure, the current power-on real-time time is obtained, and the sector number corresponding to the last valid dynamic electrocardiogram data storage sector and the power-on real-time time corresponding to the start of writing of the valid dynamic electrocardiogram data are determined to obtain the corresponding last sector number and the target power-on real-time time; based on the sector numbering sequence and the last sector number, the current sector number corresponding to the current sector used to store the currently collected dynamic electrocardiogram data is determined; according to the sampling time corresponding to the sector and the last sector number, the duration of the valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined, and the power-off duration of the last valid dynamic electrocardiogram data storage sector is determined according to the target power-on real-time time, the current power-on real-time time and the duration of the valid dynamic electrocardiogram data to obtain the target power-off duration; the preset ECG waveform data is written to the disk space corresponding to the target power-off duration in the last valid dynamic electrocardiogram data storage sector to obtain a complete ECG data recording file. It can be seen that for the event of the dynamic electrocardiogram detector being powered on again after power failure, the current power-on real-time time is obtained, and the sector number corresponding to the sector where the last valid dynamic electrocardiogram data storage before the current power-on event and the corresponding power-on real-time time when the valid electrocardiogram data starts to be written are determined, and then the current sector number is obtained, which is used to store the currently collected dynamic electrocardiogram data in the current sector corresponding to the current sector number. In this way, the valid electrocardiogram data generated by power failure and power on again is written to the new sector to distinguish it from the sector where the valid electrocardiogram data was written during the last power failure, and then the sampling time corresponding to the sector and the previous sector number are used to determine whether the dynamic electrocardiogram detector has been powered off. The effective dynamic ECG data duration stored during power-on is determined, and the power-off duration of the last effective dynamic ECG data storage sector is determined according to the target power-on real-time time, the current power-on real-time time and the effective dynamic ECG data duration, so as to obtain the target power-off duration, and finally the preset ECG waveform data is added to the disk space corresponding to the last valid dynamic ECG data storage sector occupied by the target power-off duration, to ensure that the preset ECG waveform data can be added when a power-off event occurs, and the complete ECG data record file can be obtained, avoiding the loss of ECG data caused by power-off during the storage process, facilitating the processing end to identify and process valid data files, and minimizing the adverse experience and impact caused by storage power-off.

[0062] Reference Figure 3 As shown, the embodiment of the present invention discloses a specific electrocardiogram file recording method that supports power-off persistence, in step S11: when the dynamic electrocardiogram detector is powered off and then powered on again, before obtaining the current power-on real-time time, it also includes:

[0063] Step S21: Divide the disk space of the dynamic electrocardiograph to obtain a number of sectors at different consecutive moments.

[0064] In this embodiment, the corresponding cluster information is determined based on the maximum recording time that the dynamic electrocardiogram detector can record; the disk space of the dynamic electrocardiogram detector is divided using the cluster information to obtain the corresponding clusters; the clusters are spatially divided to obtain a number of sectors at different consecutive moments. It can be understood that the number of clusters is determined based on the maximum allowed recording time, and continuous clusters are created in the disk space based on the number of clusters. For example, if the maximum allowed recording time is H, the dynamic electrocardiogram data with a recording time of H requires X clusters of space to store, and the cluster number of each cluster is defined as C1~C X In one embodiment, the maximum recording time allowed by the dynamic electrocardiograph is 24 hours. According to the maximum recording time allowed by the dynamic electrocardiograph, the memory needs 234.375M (Mega) to store the electrocardiogram data, that is, a total of 15,000 clusters are required. Then, the cluster space is further divided on each cluster to obtain several sectors at different consecutive moments. For example, each cluster is divided into Y sectors, and each sector number is defined as S1~S Y In this way, X×Y sectors are obtained.

[0065] Step S22: Based on the sectors at the several consecutive different moments, the sectors are numbered according to the cluster information of the cluster to which each sector belongs and the sector position information of the cluster to which each sector belongs, so as to obtain sector numbers corresponding to the sectors.

[0066] In this embodiment, each sector is numbered based on the cluster information of the cluster to which each sector belongs and the sector position information of each sector in the cluster to which it belongs. Specifically, when a sector is the Cth cluster, X In the cluster, the sector number is S Y When the position is, the corresponding sector number is (C X , S Y ), thus, in the process of writing dynamic ECG data, each individual sector is addressed by the sector number, and the dynamic ECG data is written into the addressed sector.

[0067] In this embodiment, the FAT16 (File Allocation Table, 16-bit) format is used as an example for explanation. It should be noted that this embodiment can also be used for other file formats such as FAT32 (File Allocation Table, 32-bit) or NTFS (New Technology File System), and no specific limitation is made thereto. In the FAT16 format, a cluster of data contains 32 sectors. When the dynamic electrocardiograph system starts recording electrocardiograph data once, the system automatically allocates the required disk space according to the 24-hour recording time set by the user, creates 15,000 continuous clusters, each cluster contains 32 sectors, and 15,000×32 sectors can be obtained. In the process of writing the collected dynamic electrocardiograph data, data writing starts from the first sector (C1, S1).

[0068] When updating the data sector, the sector number is recorded and written into the non-volatile storage area, wherein the non-volatile storage area may specifically include but is not limited to: Flash (memory), etc. Specifically, when writing the collected dynamic ECG data to a file, the sector number (C X , S Y ), recorded in the non-volatile storage area. For example: when the sector number (C5, S 10 ) sector, the sector number (C5, S 10 ) is recorded in the non-volatile storage area.

[0069] When a power outage occurs, after power is restored, the real-time power-on time and the last valid sector number are recorded, and then the ECG data is stored in the order of the sector numbers. When the processing end enters data, the actual duration data can be restored based on the recorded power-off information, where the actual duration data = storage duration data + power-off duration data.

[0070] It can be seen that the writing method of a single sector of a file replaces the commonly used method of writing a file to a cluster, which improves the data storage accuracy when restoring storage due to anomalies, greatly reduces the interference caused by errors, and facilitates the post-processing of dynamic ECG data; in addition, the storage method of pre-allocated continuous storage sectors of files can achieve stable data storage, and with the real-time recording of the recorded data sector numbers, it is convenient to accurately locate each time node, which enhances the security of the entire file data storage and also provides a reliable method for accurately finding key time nodes when repairing data anomalies.

[0071] Reference Figure 4As shown, an embodiment of the present invention discloses an electrocardiogram file recording device supporting power-off persistence, comprising:

[0072] The time acquisition module 11 is used to obtain the current power-on real-time time when the Holter monitor is powered on again after power failure, and determine the sector number corresponding to the last valid Holter data storage sector and the power-on real-time time corresponding to the start of writing the valid Holter data, and obtain the corresponding last sector number and the target power-on real-time time;

[0073] A number acquisition module 12, used to determine the current sector number corresponding to the current sector for storing the currently collected dynamic electrocardiogram data based on the sector number sequence and the previous sector number;

[0074] The power-off duration determination module 13 is used to determine the duration of valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off according to the sampling time corresponding to the sector and the last sector number, and determine the power-off duration of the last valid dynamic electrocardiogram data storage sector according to the target power-on real-time time, the current power-on real-time time and the valid dynamic electrocardiogram data duration, so as to obtain the target power-off duration;

[0075] The file recording module 14 is used to write the preset ECG waveform data into the disk space corresponding to the target power-off duration in the last valid dynamic ECG data storage sector to obtain a complete ECG data recording file.

[0076] It can be seen that the present application discloses that when the dynamic electrocardiogram detector is powered on again after being powered off, the current power-on real-time time is obtained, and the sector number corresponding to the last valid dynamic electrocardiogram data storage sector and the power-on real-time time corresponding to the start of writing of the valid dynamic electrocardiogram data are determined to obtain the corresponding last sector number and the target power-on real-time time; based on the sector numbering sequence and the last sector number, the current sector number corresponding to the current sector used to store the currently collected dynamic electrocardiogram data is determined; according to the sampling time corresponding to the sector and the last sector number, the duration of the valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined, and according to the target power-on real-time time, the current power-on real-time time and the duration of the valid dynamic electrocardiogram data, the power-off duration of the last valid dynamic electrocardiogram data storage sector is determined to obtain the target power-off duration; the preset ECG waveform data is written to the disk space corresponding to the target power-off duration in the last valid dynamic electrocardiogram data storage sector to obtain a complete ECG data record file. It can be seen that for the event of the dynamic electrocardiogram detector being powered on again after power failure, the current power-on real-time time is obtained, and the sector number corresponding to the sector where the last valid dynamic electrocardiogram data storage before the current power-on event and the corresponding power-on real-time time when the valid electrocardiogram data starts to be written are determined, and then the current sector number is obtained, which is used to store the currently collected dynamic electrocardiogram data in the current sector corresponding to the current sector number. In this way, the valid electrocardiogram data generated by power failure and power on again is written to the new sector to distinguish it from the sector where the valid electrocardiogram data was written during the last power failure, and then the sampling time corresponding to the sector and the previous sector number are used to determine whether the dynamic electrocardiogram detector has been powered off. The effective dynamic ECG data duration stored during power-on is determined, and the power-off duration of the last effective dynamic ECG data storage sector is determined according to the target power-on real-time time, the current power-on real-time time and the effective dynamic ECG data duration, so as to obtain the target power-off duration, and finally the preset ECG waveform data is added to the disk space corresponding to the last valid dynamic ECG data storage sector occupied by the target power-off duration, to ensure that the preset ECG waveform data can be added when a power-off event occurs, and the complete ECG data record file can be obtained, avoiding the loss of ECG data caused by power-off during the storage process, facilitating the processing end to identify and process valid data files, and minimizing the adverse experience and impact caused by storage power-off.
