Description

TECHNICAL FIELD

[0002] A dynamic electrocardiogram system is composed of an electrocardio recording box and a processing end, and is used for continuously recording and analyzing the changes of electrocardiogram of a heart in a human body in an active state and a quiet state within a period of time. The electrocardio recording box collects and stores electrocardio data of a user within a period of time through electrodes placed on the body surface of the user, and after the electrocardio data collection is completed, the electrocardio data is transmitted to the processing end through an SD (Secure Digital Memory Card, secure digital memory card) card and a USB (Universal Serial Bus, universal serial bus) data line transmission, and the electrocardio data is read and automatically analyzed by the processing end, so as to complete the drawing of the electrocardiogram.

[0003] Since the dynamic electrocardiogram system needs the user to wear the electrocardio recording box in real time when collecting the electrocardio data by using the electrocardio recording box, the battery of the electrocardio recording box may be in poor contact for a short time due to the movement of the user, so that the abnormal power-off occurs. In addition, in order to facilitate the use of the user, the electrocardio recording box generally uses an alkaline battery which is convenient to replace for power supply, and if the battery needs to be replaced due to insufficient power during the collection of the electrocardio data, the abnormal power-off also occurs. After the abnormal power-off occurs, the electrocardio recording box terminates the collection of the electrocardio data, so that the electrocardio data collected within a period of time is lost, and the electrocardio data obtained is incomplete. When the processing end processes the electrocardio data with data loss, the electrocardiogram drawn is extremely easy to have errors, and even cannot be drawn.

[0044] 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. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0045] The dynamic electrocardiogram system is composed of an electrocardiogram recording box and a processing end, and is used for continuously recording and analyzing the changes of electrocardiogram of a heart in a human body under active and quiet states for a period of time. The electrocardiogram recording box collects and stores electrocardiogram data of a user for a period of time through electrodes placed on the body surface of the user. After the electrocardiogram data collection is completed, the electrocardiogram data is transmitted to the processing end through an SD card and a USB data line, and the processing end reads and automatically analyzes the electrocardiogram data, so as to complete the drawing of the electrocardiogram.

[0046] Since the dynamic electrocardiogram system needs the user to wear the electrocardiogram recording box in real time when collecting electrocardiogram data by using the electrocardiogram recording box, the battery of the electrocardiogram recording box may be in short contact for a short time due to the user's movement, and thus abnormal power-off may occur. In addition, in order to facilitate the user to use, the electrocardiogram recording box generally uses alkaline batteries which are convenient to replace for power supply. If the battery needs to be replaced due to insufficient power during the collection of electrocardiogram data, abnormal power-off may also occur. After the above abnormal power-off occurs, the electrocardiogram recording box will terminate the collection of electrocardiogram data this time, so that the electrocardiogram data collected in a period of time finally appears data loss, and the electrocardiogram obtained finally is incomplete. When the processing end processes the electrocardiogram data with data loss, the electrocardiogram drawn is extremely easy to have errors, and even cannot be drawn at all.

[0047] Therefore, the application provides an electrocardiogram file recording scheme supporting power-off continuation, which can realize the recording of dynamic electrocardiogram data in the abnormal power-off process to obtain a complete electrocardiogram file during the re-power-on process after abnormal power-off.

[0048] Referring to Figure 1 The application embodiment discloses an electrocardiogram file recording method supporting power-off continuation, which comprises the following steps:

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

[0050] In the embodiment, when the dynamic electrocardiogram detector is powered off and then powered on, the current power-on real time is recorded, and the sector number corresponding to the last valid dynamic electrocardiogram data storage sector is obtained from the non-volatile storage area. The sector number is determined as the last sector number, that is, the last valid sector number. In this way, the last sector number can be used to determine the valid dynamic electrocardiogram data storage sector corresponding to the valid dynamic electrocardiogram data storage when the dynamic electrocardiogram detector is powered off, to obtain the last valid dynamic electrocardiogram data storage sector. The power-on real time corresponding to the start of writing of the valid dynamic electrocardiogram data in the last valid dynamic electrocardiogram data storage sector is obtained, to obtain the target power-on real time.

[0051] Step S12: The current sector number corresponding to the current sector for storing the currently collected dynamic electrocardiogram data is determined based on the sector number sequence and the last sector number.

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

[0053] Step S13: determining the length 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 determining 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 length of valid dynamic electrocardiogram data to obtain the target power-off duration.

[0054] In the embodiment, the length of valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined according to the sampling time corresponding to the sector and the last 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 recording electrocardiogram data is obtained by using the sector number information contained in the last sector number, and then the length of data stored for the first time when power-off occurs, that is, the length of valid dynamic electrocardiogram data, is obtained by multiplying the sampling time by the number of sectors. Then, the power-on duration of the last valid dynamic electrocardiogram data storage sector is determined based on the target power-on real-time time and the current power-on real-time time to obtain the target power-on duration; the power-off duration of the last valid dynamic electrocardiogram data storage sector is determined by using the target power-on duration and the length of valid dynamic electrocardiogram data to obtain the target power-off duration. It can be understood that the target power-on duration of the last valid 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 power-off duration of the last valid dynamic electrocardiogram data storage sector, that is, the target power-off duration, is obtained by subtracting the length of valid dynamic electrocardiogram data from the target power-on duration.

[0055] Reference Figure 2As shown, the sampling time required to write data to each sector is preset by the system or set by the user. It is important to note that a power-down event includes both a power-down process and a power-on process. When dynamic ECG data begins to be stored, the clock chip simultaneously starts timing and records the real-time time T0, which is the target power-on real-time time. When the first power-down event occurs, the clock chip continues timing, receiving a signal to record the first timing T1, which is the current power-on real-time time. The first power-on duration ΔT1 = T1 - T0, which is the target power-on duration ΔT1, can be calculated. Similarly, the second power-on duration ΔT2 = T2 - T1 can be obtained. The first power-on duration ΔT1 consists of two durations: the first data storage duration H1, which is the effective dynamic ECG data duration H1, and the first power-down duration D1, which is the target power-down duration. Therefore, ΔT1 = H1 + D1. The sector number (C) stored in the non-volatile memory area when the power-down event occurs can be read. X S Y The number of sectors containing recorded ECG data can be determined. Multiplying this number by the sampling time required for each sector allows us to calculate the initial data storage duration H1 during a power outage. The duration of the first power outage, D1, can be calculated using the formula D1 = ΔT1 - H1. Following this method, multiple ΔT values ​​can be obtained. i H i D i The value of ΣΔT. 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 duration of the first power outage is calculated as follows: first power-on time - start storage time - duration of the first data storage segment; second power outage duration is calculated as: second power-on time - first power-on time - duration of the second data storage segment; nth power outage duration is calculated as: nth power-on time - (n-1)th power-on time - duration of the nth data storage segment; last data storage duration is calculated as: total data size converted to duration - duration of each data storage segment; total recording duration is calculated as: sum of durations of each data storage segment + sum of durations of each power outage segment; actual total recording duration is calculated as: sum of durations of each data storage segment. The duration of each data storage segment can be calculated using the data sampling rate and the data size of each segment.

[0056] When a power outage occurs, the dynamic ECG file writing is interrupted. Upon power restoration, the file reads the sector number last written before the power outage from the non-volatile memory and resumes writing from the next sector. For example, the sector number read is (C5, S...). 10 If the next sector number is (C5, S), then the next sector number is (C5, S). 11), when power is on again, the data write will continue from the sector. The total length of the ECG file can be preset or set by the user. If N power-off events occur during the recording process, N+1 storage data length H and N power-off length D can be obtained.

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

[0058] In this embodiment, the preset ECG waveform data is written into the disk space corresponding to the target power-off length in the last valid dynamic ECG data storage sector, and when the dynamic ECG data recording event is detected to end, the sector offset corresponding to the target power-off length is converted, and the sector offset is performed according to the sector offset, to fill in the data of the actual length of the dynamic ECG data, obtain the target ECG data, and construct a complete ECG data record file according to the target ECG data. It can be understood that due to the power-off event occurring during the collection process, the valid collection length, i.e. the value of the storage data length H, is less than the total preset recording length of the ECG file. In order to ensure the accuracy of the data length, the processing end will supplement the storage data length H when entering the data, so that it is equal to the total preset recording length 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 length in combination with the starting storage real-time time recorded at the beginning of the storage, convert and calculate the sector offset corresponding to the power-off length, perform the sector offset, and restore the actual length data.

[0059] When the processing end analyzes the ECG data and the power-off information, the positions of each time node (the starting recording time point, the Nth power-on time point) are obtained first, the Nth power-off time point position is calculated, then the lengths of each section are calculated, i.e. the lengths of each storage section data and each power-off section, and finally the data of the Nth power-off length is supplemented at each power-off time node, so that the complete data after restoration is obtained. The power-off section length data can be uniformly supplemented as the agreed characteristic waveform data, for example, the triangular wave data of a specific frequency.

[0060] When the recording is ended, the end marker is written into the file, specifically: the file size is written, the file size attribute of the specified file root directory is changed, etc., and then the actual storage file size is recorded to prevent the file from being too large. Specifically, when the dynamic ECG data collection is completed, the dynamic ECG file is written to end, at this time the end marker is written into the last sector (C x’ , S Y’ ) and the entire ECG data record file writing is ended. When the file writing is ended, the sectors occupied by the entire ECG data record file are (C1, S1) to (C x’ , SY’ ), the sector number has been allocated but not occupied, will be released after file writing to reduce file size. It can be seen that the file end storage is updated according to the recorded continuous sector size to update the file size attribute, which not only effectively reduces the storage space occupied by the file, but also saves time for the processing end to process data in file units, which has practical significance.

[0061] It can be seen that the electrocardiogram file recording method disclosed in the application supports power-off continuation, including: when the dynamic electrocardiogram detector is powered on again after power failure, the current power-on real time is obtained, and the sector number corresponding to the last valid dynamic electrocardiogram data storage sector and the power-on real time corresponding to the start of writing of the valid dynamic electrocardiogram data are determined to obtain the corresponding last sector number and target power-on real time; the current sector number corresponding to the current sector for storing the currently collected dynamic electrocardiogram data is determined based on the sector number sequence and the last sector number; the duration of the valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined according to the sampling time corresponding to the sector and the last sector number, and the duration of the last valid dynamic electrocardiogram data storage sector when powered off is determined according to the target power-on real time, the current power-on real time and the duration of the valid dynamic electrocardiogram data to obtain a target power-off duration; and the preset electrocardiogram waveform data is written into the disk space corresponding to the target power-off duration in the last valid dynamic electrocardiogram data storage sector to obtain a complete electrocardiogram data record file. It can be seen that for the event of powering on the dynamic electrocardiogram detector again after power failure, the current power-on real time is obtained, and the sector number corresponding to the last valid dynamic electrocardiogram data storage sector before the current power-on event and the power-on real time corresponding to the start of writing of the valid electrocardiogram data are determined, and then the current sector number is obtained for storing the currently collected dynamic electrocardiogram data in the current sector corresponding to the current sector number. In this way, by writing the valid electrocardiogram data generated after power failure into a new sector, the sector is distinguished from the sector in which the valid electrocardiogram data is written when the last power failure occurs. Then, the duration of the valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined according to the sampling time corresponding to the sector and the last sector number, and the duration of the last valid dynamic electrocardiogram data storage sector when powered off is determined according to the target power-on real time, the current power-on real time and the duration of the valid dynamic electrocardiogram data to obtain a target power-off duration. Finally, the preset electrocardiogram waveform data is supplemented into the disk space corresponding to the last valid dynamic electrocardiogram data storage sector occupied by the target power-off duration, which ensures that the preset electrocardiogram waveform data can be supplemented when a power failure occurs, complete electrocardiogram data record files can be obtained, the missing of electrocardiogram data caused by power failure during storage is avoided, the processing end can identify and process valid data files, and the adverse experience and influence caused by storage power failure are minimized.

[0062] With reference to Figure 3 The embodiment of the present application discloses a specific power-off persistent electrocardiogram file recording method, which comprises the following steps:

[0063] Step S21: dividing the disk space of the dynamic electrocardiogram detector to obtain sectors at a plurality of continuous time points.

[0064] In the embodiment, the cluster information is determined based on the maximum recording duration of the dynamic electrocardiogram detector; the disk space of the dynamic electrocardiogram detector is divided by using the cluster information to obtain corresponding clusters; and the clusters are divided in space to obtain sectors at a plurality of continuous time points. It can be understood that the number of clusters is determined according to the maximum recording duration, and the continuous clusters are created in the disk space based on the number of clusters, for example, the maximum recording duration allowed for writing is H, and the dynamic electrocardiogram data with a recording duration of H requires X clusters of space for storage, and the cluster numbers of each cluster are defined as C1-CX. X In an embodiment, the maximum duration allowed for recording by the dynamic electrocardiogram detector is 24 hours, and according to the maximum duration allowed for recording by the dynamic electrocardiogram detector, the memory needs to store 234.375M (Mega, megabytes) of electrocardiogram data, that is, a total of 15000 clusters. Then, the cluster space is further divided on each cluster to obtain sectors at a plurality of continuous time points. For example, each cluster is divided into Y sectors, and each sector number is defined as S1-SY. Y In this way, X×Y sectors are obtained.

[0065] Step S22: numbering the sectors based on the cluster information of the clusters to which the sectors belong and the sector position information of the sectors in the clusters to which the sectors belong, to obtain sector numbers corresponding to the sectors.

[0066] In the embodiment, each sector is numbered based on the cluster information of the cluster to which the sector belongs and the sector position information of the sector in the cluster to which the sector belongs. Specifically, when a sector is in the C X th cluster and the sector number is S Y , the corresponding sector number is (C X , S Y ). In this way, during the writing of dynamic electrocardiogram data, each individual sector is addressed by the sector number, and the dynamic electrocardiogram data is written in the addressed sector.

[0067] The embodiment takes the FAT16 (File Allocation Table, 16-bit) format as an example for illustration, and it should be noted that the embodiment can also be used for FAT32 (File Allocation Table, 32-bit) or NTFS (New Technology File System) and other file formats, and no specific limitation is made in this regard. In the FAT16 format, one cluster of data contains 32 sectors, and when the dynamic electrocardiogram system starts a recording of electrocardiogram data, the system automatically allocates the required disk space according to the 24-hour recording time set by the user, creates 15000 continuous clusters, each cluster contains 32 sectors, and then 15000*32 sectors can be obtained. In the process of writing the collected dynamic electrocardiogram 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, which can include but is not limited to Flash (memory) and the like. Specifically, when writing a file of the collected dynamic electrocardiogram data, the sector number (C X , S Y ) of each sector is recorded into the non-volatile storage area after the data writing of the sector is completed. For example, when the data writing of the sector with the sector number (C5, S 10 ) is completed, the sector number (C5, S 10 ) corresponding to the sector is recorded into the non-volatile storage area.

[0069] When a power failure occurs, after power-up, the real-time time of the power-up and the last valid sector number are recorded, and then the electrocardiogram data is continuously stored according to the sector number order. When the processing end enters data, the actual duration data can be recovered according to the recorded power failure information, where the actual duration data = storage duration data + power failure duration data.

[0070] As can be seen, the writing method of a single sector of a file replaces the commonly used file writing method of a cluster, improves the data storage accuracy when recovering storage due to abnormalities, greatly reduces the interference caused by errors, and facilitates the post-processing of dynamic electrocardiogram data. In addition, the continuous storage sector pre-allocation storage method can realize stable data storage, and the real-time recording of the recorded data sector number facilitates accurate positioning of each time node, enhances the security of the entire file data storage, and also provides a reliable method for accurately finding the key time node when repairing data abnormalities.

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

[0072] The time acquisition module 11 is configured to acquire current power-on real time when the dynamic electrocardiogram detector is powered on again after power-off, determine the sector number corresponding to the last valid dynamic electrocardiogram data storage sector and the power-on real time corresponding to the start of writing of the valid dynamic electrocardiogram data, and obtain the corresponding last sector number and target power-on real time.

[0073] The sector number acquisition module 12 is configured 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 last sector number.

[0074] The power-off duration determination module 13 is configured to determine the duration of the 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, the current power-on real time and the duration of the valid dynamic electrocardiogram data, so as to obtain the target power-off duration.

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

[0076] Therefore, the application discloses the following technical scheme. When the dynamic electrocardiogram detector is powered off and then powered on, the current power-on real time is obtained, the sector number corresponding to the last valid dynamic electrocardiogram data storage sector and the power-on real time corresponding to the start of writing of the valid dynamic electrocardiogram data are determined, the corresponding last sector number and target power-on real time are obtained, the current sector number corresponding to the current sector for storing the currently collected dynamic electrocardiogram data is determined based on the sector number sequence and the last sector number, the duration of the valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined according to the sampling time corresponding to the sector and the last sector number, and the power-off duration of the last valid dynamic electrocardiogram data storage sector is determined according to the target power-on real time, the current power-on real time and the duration of the valid dynamic electrocardiogram data, so as to obtain the target power-off duration. The preset electrocardiogram waveform data is written into the disk space corresponding to the target power-off duration in the last valid dynamic electrocardiogram data storage sector, so as to obtain a complete electrocardiogram data record file. It can be seen that, for the event that the dynamic electrocardiogram detector is powered off and then powered on, the current power-on real time is obtained, the sector number corresponding to the last valid dynamic electrocardiogram data storage sector before the current power-on event and the power-on real time corresponding to the start of writing of the valid electrocardiogram data are determined, the current sector number is obtained, and the currently collected dynamic electrocardiogram data is stored in the current sector corresponding to the current sector number. In this way, the valid electrocardiogram data generated after power-off and power-on is written into a new sector, so as to be distinguished from the sector in which the valid electrocardiogram data is written when the power is last powered off. Then, the duration of the valid dynamic electrocardiogram data stored when the dynamic electrocardiogram detector is powered off is determined according to the sampling time corresponding to the sector and the last sector number, and the power-off duration of the last valid dynamic electrocardiogram data storage sector is determined according to the target power-on real time, the current power-on real time and the duration of the valid dynamic electrocardiogram data, so as to obtain the target power-off duration. Finally, the preset electrocardiogram waveform data is supplemented into the disk space corresponding to the last valid dynamic electrocardiogram data storage sector occupied by the target power-off duration, so as to ensure that the preset electrocardiogram waveform data can be supplemented when the power-off event occurs, complete electrocardiogram data record files can be obtained, the missing electrocardiogram data caused by power-off during storage is avoided, the processing end can identify and process the valid data file, and the adverse experience and influence caused by power-off during storage are minimized.
