And, can also carry out batch comparison, analysis and statistics to a large amount of inventory data.
When used inventory data is located on an electrocardiogram workstation or a cloud platform, a data file can be searched and acquired by directly utilizing a high-efficiency engine of a remote professional database in an online mode, so that smooth experience of a user is guaranteed.

However, with the rapid expansion and cost reduction of the storage carrier in the market, when the conventional electrocardiograph also has mass data storage capacity (at least thousands or even tens of thousands of files can be stored), if the storage mode still uses the previous file traversal method to search for the data file, the time consumption of the device processor is too long due to too many traversed files, and thus, the bad experiences of false halt, interface pause and the like are caused to the user.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Before the present invention is explained in further detail by way of examples, a brief description of several documents of electrocardiographs mentioned herein is provided.
The data file, which is mentioned in the embodiment of the present invention, is a file stored locally in the electrocardiogram machine. The file is mainly used for storing some data information related to patients and patient detection, and also includes some information related to data file creation, such as: file type, data file name, file creation date, file creation time, patient identification, patient name, patient gender, patient age, patient electrocardiographic waveform, patient measurement, patient analysis, patient heartbeat information, patient representative heartbeat data, patient lead data, device parameters, and the like.
The index file, which is mentioned in the embodiment of the present invention, is a file stored locally in the electrocardiogram machine and used for establishing a corresponding relationship with all data files. The index file stores a record counter and a plurality of index records, and each index record corresponds to one data file. The storage content of the index record comprises index record identification, data file name, file type, file creation date, file creation time, patient identification, patient name, patient sex, patient age, patient analysis result and the like; the index record identification is used for uniquely identifying each index record, and information such as a data file name, a file type, a file creation date, a file creation time, a patient identification, a patient name, a patient sex, a patient age, a patient analysis result and the like is consistent with information in the data file corresponding to the index record. Conventionally, after each data file is successfully created, a corresponding index record is added to the index file to match the index record.
The file storage list, which is mentioned in the embodiments of the present invention, is a vector table stored locally in the electrocardiogram machine and used for establishing a correspondence between a storage file name and file physical storage location information for all files (including index files, data files, and other files). The file storage list comprises a plurality of file storage records; each file storage record corresponds to one file; each file storage record includes at least two data: storing a file name (the corresponding index file is the index file name, the corresponding data file is the data file name) and file physical storage location information (the actual physical storage address or area information on the storage carrier). Each write operation (create, modify, delete) to a file will modify the table accordingly. The File storage list may be in a custom format of the embedded operating system, or may also adopt a common data format such as a 16-bit File Allocation Table (FAT 16), a 32-bit File Allocation Table (FAT 32), and the specific implementation is determined according to the engineering implementation requirements.
In specific use, an electrocardiograph often involves providing a user with list browsing of searched files through a human-computer interaction interface, and extracting corresponding specific information of a file according to a file selected by the user on the human-computer interaction interface, as shown in fig. 1, which is a schematic diagram of a data file searching method provided in an embodiment of the present invention, the method mainly includes the following steps:
the electrocardiograph provides a plurality of human-computer interaction interface modes for users: an Application Program Interface (API) mode, a command mode using a command console, or a window mode in which a display device is used to present a visual Interface; the file query processing flow started in the step 1 has a customized activation means under each interactive mode: the method comprises the following steps that a user uses a customized file list acquisition interface to activate in an API mode, the user uses information input equipment such as a keyboard and a mouse of an electrocardiograph to input a file list acquisition instruction to activate in an instruction mode, and the user uses the information input equipment such as the keyboard, the mouse and a touch screen of the electrocardiograph to click a file list function provided in the interface in a window mode to generate a file list acquisition instruction to activate; in addition, the three modes are not limited to the electrocardiograph, and can also be equipment with API, instruction desk and window capability, such as a mobile phone, a PAD, a computer and the like, which is connected with the electrocardiograph through a network;
the storage carrier mentioned herein is a storage medium used for storing all files (including index files, data files, file storage lists, etc.) locally for the electrocardiograph, and the specific implementation of the storage carrier can be an independent storage medium on the electrocardiograph or a combined storage body composed of a plurality of independent storage media;
the index file data set comprises a record counter and a plurality of index records; the index record comprises an index record identifier, a data file name, a file type, a file creation date, a file creation time, a patient identifier, a patient name, a patient sex, a patient age and a patient analysis result;
the file storage list comprises a plurality of file storage records; the file storage record at least comprises a storage file name and file physical storage position information;
the method specifically comprises the following steps: step 11, initializing the index file by the electrocardiograph, wherein the reading result of the index file is reading failure, and the data set of the index file is empty;
if the subsequent steps cannot be normally completed, on one hand, the reading result of the index file does not need to be judged and set, and on the other hand, the electrocardiogram activates the reconstruction processing process of the index file according to the reading failure state of the index file;
step 12, the electrocardiograph polls the file storage records included in the file storage list according to the default index file name; and when the storage file name included in the file storage record is equal to the index file name, acquiring the physical storage data of the index file from the storage carrier according to the file physical storage position information included in the file storage record to generate an index file data set, and setting the index file reading result as the successful reading.
The default file name is set for the habitual operation of the index file, so that the electrocardiograph does not need to perform secondary screening acquisition processing on the name when performing the operation of the index file, operation steps can be saved, and the file access efficiency can be improved; assuming that the index file name defaults to IXF, assume that the file storage list includes 3 file storage records: file storage record 1 (storage file name is IXC, file physical storage location information is address 1), file storage record 2 (storage file name is IXF, file physical storage location information is address 2), and file storage record 3 (storage file name is IX, file physical storage location information is address 3); when polling is carried out on the file storage records included in the file storage list, when the file storage record 1 is polled, the file storage record 2 is switched to because the storage file name is not equal to the index file name; when polling to the file storage record 2, the current polling is stopped because the storage file name is equal to the index file name, and all the storage data of the index file are acquired from the storage space pointed by the address 2 of the file storage record 2 to generate an index file data set. After the electrocardiograph acquires the index file data set from the index file, the traversal search of all the data files on the storage carrier is completed.
Step 2, when the reading result of the index file is successful, counting the total number of index records included in the index file data set by the electrocardiograph to generate the total number of index records, and performing the total number of index records verification operation on the total number of index records by using a record counter to generate the total number of index records verification result;
the method specifically comprises the following steps: when the reading result of the index file is that the reading is successful, counting the total number of the index records included in the index file data set by the electrocardiograph to generate the total number of the index records; and judging whether the record counter is equal to the total number of the index records or not, setting the total number of the index records as verification success when the record counter is equal to the total number of the index records, and setting the total number of the index records as verification failure when the record counter is not equal to the total number of the index records.
Here, the record counter of the index file data set is modified after the index record is operated (added or deleted) each time, and if unpredictable accidents such as power failure occur during modification, modification failure may be caused, so that the counter is not matched with the total number of actual index records; therefore, after the data of the index file is acquired, the number of records of the index file needs to be corrected; the specific proofreading principle is to compare whether the actual total number of index records is equal to the value of the record counter, and if the actual total number of index records is not equal to the value of the record counter (the proofreading fails), the conventional processing is to stop the file searching processing flow and activate the corresponding processing flow in the electrocardiogram machine.
the method specifically comprises the following steps: step 31, the electrocardiograph generates a file list by using the index file data set, and performs file list display operation to a user according to the file list; the electrocardiograph also provides a file record selection function for the user while displaying the file list for the user;
wherein the file list comprises a plurality of file records; the file records of the file list and the index records of the index file data set are in one-to-one correspondence;
here, the electrocardiograph copies all index records of the index file data set to a file list, and the file list is also composed of a plurality of file records, so that each file record realizes a one-to-one correspondence relationship with the index records in the index file data set;
then, the electrocardiograph displays a file list to the user based on different human-computer interaction modes: under the API mode, providing a file list for an application program through an application program interface; under the instruction mode, a file list is presented to a user through an instruction console; under a window mode, a file list interface is presented to a user through display equipment of the electrocardiograph;
step 32, the electrocardiograph generates a current file record according to a file record selection result of the user on the file list; and extracting the index record identifier of the index record corresponding to the current file record from the index file data set to generate a current index record identifier.
Here, the electrocardiograph obtains a file record selection result of the user on the file list based on different human-computer interaction modes to generate a current file record: under the API mode, acquiring a file record selection result transmitted to the electrocardiograph by a user through an application program interface to generate a current file record; under the instruction mode, acquiring a file record selection result input by a user through information input equipment such as a keyboard, a mouse and the like of the electrocardiograph to generate a current file record, and under the window mode, acquiring a file record selection result clicked by the user through the information input equipment such as the keyboard, the mouse, a touch screen and the like of the electrocardiograph to generate a current file record;
the electrocardiograph may then extract the index identifier from the index record corresponding to the file record to generate a current index identifier (the index record identifier of the currently selected index record).
the method specifically comprises the following steps: step 41, initializing the file name of the current data to be null by the electrocardiograph;
step 42, the electrocardiograph polls the index records included in the index file data set according to the current index record identification; and when the index record identifier included in the index record is equal to the current index record identifier, extracting the data file name included in the index record to generate the current data file name.
Here, assuming that the current index record is identified as 2, the index file data set includes 2 index records: when polling to index record 1, because the index record identifier is not equal to the current index record identifier, directly switching to the next index record; when polling to index record 2, because the index record identification is equal to the current index record identification, extracting the data file name (IX) of index record 2 and setting the current data file name.
the method specifically comprises the following steps: step 51, the reading result of the electrocardiograph initialized data file is that reading fails, and the data set of the initialized data file is empty;
step 52, the electrocardiograph polls the file storage records included in the file storage list according to the current data file name; and when the storage file name included in the file storage record is equal to the current data file name, acquiring the physical storage data of the current data file from the storage carrier according to the file physical storage position information included in the file storage record to generate a data file data set, and setting the data file reading result as the reading success.
Here, assuming that the current data file name is IX, the file storage list includes 3 file storage records: file storage record 1 (storage file name is IXC, file physical storage location information is address 1), file storage record 2 (storage file name is IXF, file physical storage location information is address 2), and file storage record 3 (storage file name is IX, file physical storage location information is address 3); when polling is carried out on file storage records included in the file storage list, when the file storage record 1 is polled, the file storage record 2 is switched to because the file name of the storage file is not equal to the file name of the current data; when polling to the file storage record 2, because the storage file name is not equal to the current data file name, switching to the file storage record 3; when polling to the file storage record 3, the current polling is stopped because the storage file name is equal to the current data file name, and all the storage data of the data file are acquired from the storage space pointed by the address 3 of the file storage record 3 to generate a data file data set.
And 6, when the reading result of the data file is successful and the data set of the data file is not empty, setting the search result of the data file as successful search by the electrocardiograph.
Here, in order to prevent a storage medium reading error caused by a component failure of a storage carrier from occurring when the content of a data file is acquired, a data file reading result and a data file data set are subjected to double acceptance, that is, it is considered that the data file searching process is completely successful only when both of the data file reading result and the data file data set are in a normal state (the data file reading result is successful, and the data file data set is not empty). After the data file search process is completely successful, the electrocardiogram will perform the next operations on the data file related to display and modification.
When an electrocardiograph starts a file traversal and search processing flow, firstly, an index file is positioned in a first step, and in practical application, when index file positioning may cause a situation of index file search failure, the electrocardiograph is required to provide a processing flow for reconstructing the index file, as shown in fig. 2, which is a schematic diagram of an index file error processing method provided by a second embodiment of the present invention, the method mainly includes the following steps:
wherein the index file data set comprises a record counter and a plurality of index records; the index record comprises an index record identifier, a data file name, a file type, a file creation date, a file creation time, a patient identifier, a patient name, a patient sex, a patient age and a patient analysis result;
the file storage list comprises a plurality of file storage records; the file storage record at least comprises a storage file name and file physical storage position information;
the method specifically comprises the following steps: step 1011, the electrocardiograph initializes the index file and reads the result as reading failure, initializes the index file data set as empty;
step 1012, the electrocardiograph polls the file storage records included in the file storage list according to the default index file name; and when the storage file name included in the file storage record is equal to the index file name, acquiring the physical storage data of the index file from the storage carrier according to the file physical storage position information included in the file storage record to generate an index file data set, and setting the index file reading result as the successful reading.
The default file name is set for the habitual operation of the index file, so that the electrocardiograph does not need to perform secondary screening acquisition processing on the name when performing the operation of the index file, operation steps can be saved, and the file access efficiency can be improved; assuming that the default index file name is IXF, assume that the file storage list includes 3 file storage records: file storage record 1 (storage file name IXC, file physical storage location information address 1), file storage record 2 (storage file name IXA, file physical storage location information address 2), and file storage record 3 (storage file name IX, file physical storage location information address 3); when polling is carried out on the file storage records included in the file storage list, when the file storage record 1 is polled, the file storage record 2 is switched to because the storage file name is not equal to the index file name; when polling to the file storage record 2, because the storage file name is not equal to the index file name, then switching to the file storage record 3; when polling to the file storage record 3, because the storage file name is not equal to the index file name, and because there are no more index records, ending the file storage list; after the polling is finished, since no file storage record matching the index file name is found all the time, the index file reading result should be kept in an initial value state: the read fails and the index file data set is also empty.
And 102, when the reading result of the index file is reading failure, the electrocardiograph creates the index file according to the index file name and initializes the recording counter of the index file to be 0.
Here, because the index file does not exist, the electrocardiograph reconstructs the index file, and the first step of reconstruction is to create an empty index file to prepare for content addition of subsequent index files.
103, reconstructing the index file by using the file storage list by the electrocardiograph;
the method specifically comprises the following steps: traversing all file storage records included in the file storage list by the electrocardiograph; and when the current file type is a data file type, extracting the file type, the file creation date, the file creation time, the patient identification, the patient name, the patient sex, the patient age and the patient analysis result of the file to form an index record and adding the index record to the index file.
Before each index record adding operation, a unique index record identifier needs to be automatically allocated to be attached to the index record; after each index record add operation, the record counter of the index file needs to be incremented by 1 to match the actual total number of index records.
The electrocardiograph uses a file storage list as a file large linked list, uses the linked list to check the file type of each file stored on a storage carrier of the electrocardiograph, extracts related data from the data file to assemble into an index record according to the data comparison relation between the data file and the index record if the file is a data file (or a file which needs to be managed by using the index file), and then uses the record to add the index file; after all the files are traversed, the index file is rebuilt.

The memory may be connected to the processor by a bus.
