Abstract
The invention discloses an electrocardiogram data storage method for multi-interconnection dynamic switching. The method is characterized by comprising the following steps of: 1, acquiring eight lead signals I, II, V1 to V6 in electrocardiogram signals at fixed time intervals; 2, coding and storing the electrocardiogram signals acquired every time to an information block, wherein each information block contains an information header and a subsequent data block; 2.1, storing and resolving the required information of the data block in the information header, and storing the link statuses of the eight lead signals; and 2.2, according to the link status of each lead signal stored in the step 2.1, only storing the data of the lead signals in the link statuses in a data block region without storing the data of other lead signals. The storage method not only occupies a small storage space, but also is convenient to resolve, move and store the data due to blocking storage.
Description
Technical field
The present invention relates to the electrocardiogram (ECG) data storage means, be specifically related to the electrocardiogram (ECG) data storage means that a kind of multi-lead dynamically switches.
Background technology
In the portable cardiac device, because the signal record time is long, data volume is huge, the status that the storage of electrocardiogram (ECG) data has particular importance to the practicality of installing.According to the actual monitoring demand, the connection situation difference of each cardiac diagnosis lead signal, the part lead signals is in vacant state, existing portable cardiac device often adopts the data memory format of regular length, for vacant lead signals, data with a specific mark are filled, and have greatly wasted finite storage space; And all electrocardiogram (ECG) datas are stored in the big data block, do not have the piecemeal storage, are unfavorable for the analysis, moving and storage of data.
Summary of the invention
The invention provides the electrocardiogram (ECG) data storage means that a kind of multi-lead dynamically switches, it is little that this kind storage means is not only occupied memory space, and because the piecemeal storage makes things convenient for the analysis, moving and storage of data.
In order to reach above technique effect, this method comprises following steps:
Step 2.1, in information header the necessary information of storing and resolving notebook data piece, and store the connection status of described eight lead signals;
Step 2.2, according to the connection status of each lead signals of storage in the step 2.1, in the data block zone, only storage is in the data of the lead signals of connection status, the data of other lead signals are not then stored.
The necessary information of the information header storing and resolving notebook data piece in the described step 2.1 comprises the sampling precision of sample frequency and each signalling channel.
In the described step 2.1, utilize 1 byte to store I successively, II, the connection status of eight lead signals of V1～V6; Wherein, the connection status of a lead signals of each bit storage;
If lead signals does not connect, vacant or malunion Chang Ze is recorded as 0, and is normal if lead signals connects, and then is recorded as 1.
In the data block zone, the storage of each lead signals data needs 1.5 bytes.
If there be n lead signals to be in connection status, then in data block, take
Byte is stored the lead signals data that are in connection status;
Wherein, if n is an odd number, use 0 polishing for back four of last then shared byte.
The present invention has following advantage:
Each chunk all by one independently information header mark each lead signals state, when lead signals switches, the actual connection situation of lead signals when different chunk has write down information gathering at that time;
2. all lead signals are not stored in the data field, state according to each dynamically labeled lead signals of the mode bit of lead signals in the information header, the lead signals of normal connection is only write down in the data field, thereby reduces the storage of invalid signals largely, has made full use of finite storage space;
3. deblocking storage is stored as different chunk with electrocardiosignal at interval with regular time, make things convenient for data copy, move and with file or the storage of data base's form;
4. the information header of each chunk has write down electrocardiosignal and has resolved needed information, has made things convenient for the parsing of electrocardiosignal;
With regular time at interval as the standard of dividing different chunk, division rule is simple, electrocardio is resolved and is made things convenient for.
Description of drawings
Fig. 1 is I of the present invention, II, the connection status record sketch map of eight lead signals of V1～V6;
Fig. 2 is the shared spatial sketch map of lead signals of the present invention;
Fig. 3 is the dynamically flow chart of the electrocardiogram (ECG) data storage means of switching of multi-lead of the present invention.
The specific embodiment
Followingly specify the specific embodiment of the present invention according to Fig. 1～3.
Performing step of the present invention is as follows:
The necessary information of step 2.1, information header storing and resolving notebook data piece, described necessary information comprises the sampling precision of sample frequency, each signalling channel etc., especially, also stores the connection status of eight lead signals;
As shown in Figure 1, be I, II, the connection status storage sketch map of eight lead signals of V1～V6.In the information header of each chunk,, store I respectively on the every bit of this byte, II, the connection status of eight lead signals of V1～V6 with the connection status of 1 byte (byte) storage lead signals.For example, the connection status value of record I lead signals on 0 in this byte, 1 connection status value that goes up record II lead signals, 2～7 connection status values that go up six lead signals of record V1～V6, if lead signals do not connect, vacant or malunion often then the connection status value record be 0, if lead signals connects normal, then the connection status value record is 1.Like this, value is that 1 lead signals is exactly that all connect normal lead signals.
Step 2.2, in the data block zone, connection status is shown as the lead signals of connection in the stored information head, other lead signals are not stored.
As shown in Figure 2, each lead signals takies 1.5 bytes, if n lead signals connection, the then data occupancy of once sampling are arranged
0 polishing if n is an odd number, is then used for back four of last byte in the Bytes space.Symbol
Expression rounds up, for example, if in a data block, there are 4 lead signals to connect, then the space of Cai Yang data occupancy is 6 bytes, if in a data block, there are 5 lead signals to connect, then the space of Cai Yang data occupancy is 8 bytes, last byte back four neat with spot patch.
Electrocardiogram (ECG) data according to above-mentioned storage format storage has following advantage:
Each chunk all by one independently information header mark each lead signals state, when lead signals switches, the actual connection situation of lead signals when different chunk has write down information gathering at that time;
2. all lead signals are not stored in the data field, state according to each dynamically labeled lead signals of lead signals mode bit in the information header, the lead signals of normal connection is only write down in the data field, thereby reduces the storage of invalid signals largely, has made full use of finite storage space;
3. deblocking storage is stored as different chunk with electrocardiosignal at interval with regular time, make things convenient for data copy, move and with file or the storage of data base's form;
4. the information header of each chunk has write down electrocardiosignal and has resolved needed information, has made things convenient for the parsing of electrocardiosignal;
With regular time at interval as the standard of dividing different chunk, division rule is simple, electrocardio is resolved and is made things convenient for.
Although content of the present invention has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited to the appended claims.
