Description

Technical Field

[0001] The present application relates to the technical field of software upgrade, and in particular to an upgrade method and device based on an EIT equipment software database. Background Art

[0002] In the current software technology field, there are many solutions to the problem of upgrading local databases. However, these solutions have certain limitations when applied to EIT equipment software.

[0003] The following are several existing technical solutions similar to the present invention and their shortcomings: 1) Update the user's local database through the network: rely on network connection to achieve database update. However, current EIT devices and devices under development generally do not support network functions. Since network functions are not a rigid demand for EIT devices, and medical devices will face complex network security regulatory challenges if network functions are added, this solution cannot be applied to EIT device software. 2) Overwrite and upgrade the original database: directly replace the original database with a new version of the database. However, EIT devices process important user data, and simple overwrite upgrades may cause data loss. Even if the data is exported and imported into the new version of the database before overwriting, it cannot be guaranteed that the database version and the software version are completely matched, which may cause software operation errors. 3) Rebuild the database and import the original user data when the EIT device software is running: rebuild the database structure when the software is running, and import the original user data into the new database. However, if the database is large or the user data is numerous, this process will be very time-consuming. In addition, this solution increases the complexity of the business process and requires handling various exceptions during database reconstruction or data import, which increases the risk of software defects. More importantly, in order to ensure that the rebuilt database is always up to date, each software version needs to modify the database reconstruction function, which is not in line with the open-closed principle in software development and is not conducive to software maintenance and expansion. Summary of the invention

[0004] An object of an embodiment of the present invention is to provide an upgrade method and device based on an EIT device software database, which is used to solve technical problems such as changing requirements, inability to use the network, ensuring user data security, compatibility with new versions of software, and inability to determine user software versions during the upgrade process of the host computer software of EIT equipment products.

[0024] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The technical solution of the present application can be applied to software upgrade scenarios of various EIR devices.

[0027] In view of this, the present application proposes an upgrade method based on the EIT device software database to solve the above problems, which is described in detail below.

[0028] See also Figure 1A , Figure 1A A flowchart of an upgrade method based on an EIT device software database provided by an embodiment of the present invention, the method comprising the following steps:

[0029] S10: Obtain a database version number of a current database of an EIT device, wherein the EIT device has a database upgrade function.

[0030] Among them, EIT (Electrical Impedance Tomography) equipment is a biomedical device that uses electrical impedance tomography technology for monitoring and imaging. It usually includes a hardware part for data acquisition and a software part for data processing and storage.

[0031] Therefore, this solution proposes an EIT device with database upgrade function, which can update the database in its software system. Such updates may include but are not limited to changes in table structure, addition or deletion of data fields, optimization of indexes, modification of stored procedures, etc.

[0032] The database version number is information used to identify the current status and version of the database. The database version number can be a number, a string, or any identifier that can indicate the version difference. Different versions of databases may contain different data structures, tables, indexes, and stored procedures. The EIT device obtains the version number of the current database through a specific query command or API interface.

[0033] It can be seen that the database upgrade function of the EIT device in this embodiment ensures that the device can keep the data structure up to date as the software is updated, thereby supporting the use of new functions while maintaining stability and data security.

[0034] S20. According to the database version number, query the operation corresponding to the database version number.

[0035] Each database version number corresponds to a specific set of operations. These operations may include the execution of SQL scripts, data migration, table structure changes, index creation or deletion, etc. These operations are designed to convert the database from an old version to a new version.

[0036] Among them, the version number of the current database is obtained through a specific query command or API interface. According to the obtained version number, a query statement is constructed or the API interface is called to retrieve the corresponding operation list from the operation library; the operation steps and instructions corresponding to the current version number are obtained. These operation steps are usually arranged in sequence to ensure the orderly progress of the upgrade or maintenance process; the query results are parsed to generate a specific operation instruction list. Each operation instruction contains detailed execution steps and parameters to ensure the accuracy of the operation.

[0037] It can be seen that in this embodiment, by querying the operation corresponding to the database version number, it is ensured that each upgrade or maintenance operation is based on the correct steps of the current database version, avoiding database problems caused by improper operation, and being able to flexibly respond to different versions of databases, ensuring the compatibility and scalability of the device in different version environments.

[0038] S30: Upgrade the database of the EIT device according to the operation corresponding to the database version number.

[0039] Among them, an upgrade is a series of predefined steps that may include SQL statements, program code, configuration changes, etc., aimed at modifying the structure, content or configuration of the database to make it compatible with the latest version of the software.

[0040] Among them, the upgrade process is started according to the difference between the current version number of the database and the target version number.

[0041] Optionally, after the upgrade operation completes successfully, the database version number is updated to reflect the new database state.

[0042] Optionally, before performing a database upgrade, you can back up the current database to prevent data loss due to unexpected situations during the upgrade process. This can be achieved through database backup tools or commands.

[0043] It can be seen that in this embodiment, the automated upgrade process reduces human operation errors and improves upgrade efficiency and accuracy.

[0044] It should be noted that the process of S10-S30 of this solution does not require a network communication connection, that is, the process of this solution can still be executed without a network.

[0045] By acquiring the database version number of the current database of the EIT device, the method can accurately manage the database version in the EIT device to ensure that each version of the database can be accurately identified and processed; according to the database version number, the corresponding upgrade operation is queried, and the database is upgraded according to these operations, which can realize the automatic upgrade process of the database, reduce manual intervention, and improve the upgrade efficiency; further, by querying the operation corresponding to the database version number, it can be ensured that each upgrade operation is based on the correct steps of the current database version, thereby reducing the risk of errors in the upgrade process and ensuring the stability and reliability of the database upgrade; further, corresponding operations can be performed according to different database version numbers, so that the EIT device can flexibly respond to different versions of the database and ensure the compatibility and scalability of the device. Therefore, the method can reduce the workload of maintenance personnel, reduce maintenance costs, and can quickly respond to the update requirements of the database version, thereby improving the maintenance efficiency of the device.

[0046] In one embodiment, before obtaining the database version number of the current database of the EIT device, the method further includes: querying whether a version field exists in the structure corresponding to the database in the EIT device, and the version field is used to record the version number of the current database; if the version field does not exist, adding a target version field according to a preset operation, and the target version field indicates an identification of the starting version of the current database.

[0047] The version field is a special field in the database that stores an identifier that represents the version number of the database. The version field is usually a column containing version number information and is located in a specific table in the database (for example, the metadata table or the version_info table).

[0048] The specific process of the query may be to check the structure of the database (usually metadata or system tables) to determine whether there is a version field. For example, in a SQL database, query INFORMATION_SCHEMA.COLUMNS or other system views to find the version field.

[0049] The preset operations are usually database migration scripts or update statements, which define how to add a new version field to the existing database structure.

[0050] When performing a database upgrade operation, the current database version number can be determined by querying the value of the version field.

[0051] Optionally, after adding the version field, set the starting version number for it. The starting version number usually indicates the starting version of the database and can be set according to the actual situation. For example, if the database is initially V1.0.0, the system will add a version field and set its value to '1.0.0'.

[0052] The operation of adding the version field should be performed in a transaction to ensure the atomicity of the operation and avoid errors in the process that may cause inconsistent database status.

[0053] It can be seen that in this embodiment, the above process can ensure that each database instance has a clear version number.

[0054] In one embodiment, obtaining the database version number of the current database of the EIT device includes: querying a corresponding version field in the current database of the EIT device; and determining the database version number of the current database according to the version field.

[0055] The query may be performed by executing an SQL query. For example, in an SQL database, a statement similar to SELECT version_field FROM system_table may be used to obtain the value of the version field.

[0056] Once the version field is found, the value of the field is read, and this value is the version number of the current database.

[0057] Optionally, if it is found during the query process that the version field does not exist or the version number format is incorrect, the abnormal situation is handled according to the error handling mechanism, such as prompting the user with an error message or trying to restore to the last known good version.

[0058] The version number usually follows a certain format, such as "major version number.minor version number.revision number" (for example, 1.0.0). This format helps to compare the new and old versions and determine the upgrade path.

[0059] It can be seen that, in this embodiment, by managing the version field, the consistency and reliability of the database structure and data can be ensured, and problems caused by version inconsistency can be reduced.

[0060] In one embodiment, querying the operation corresponding to the database version number based on the database version number includes: determining whether the database version number matches the version number of the version class object stored in the data structure; if not, setting the current version number of the database as the target version number; based on the target version number, traversing the data structure in the EIT device to obtain at least one target operation, the target operation being an operation corresponding to a version number higher than the target version number, the data structure representing a collection of version class objects stored in the EIT device, and the arrangement order in the data structure being in ascending order according to the version numbers in the version class objects stored in the EIT device; wherein the version class object is a version class and a corresponding information set, the version class corresponds to a version number, the version class is used to implement a version interface, and the version interface includes all steps implemented by the database version class.

[0061] The data structure is a collection that contains multiple version objects, each of which represents a specific version of the database and its related upgrade operations. The data structure can be a list, array, stack, queue, etc., which organizes version objects according to version numbers or in a specific order.

[0062] If the version number of the current database does not match the version number of any version class object in the data structure, the version number of the current database is set as the target version number.

[0063] Among them, the version interface (Version Interface) defines one or more methods, which are standards for implementing the version control function. Usually, these methods include upgrade (upgrade), downgrade (downgrade) and obtaining the version number (version). The version interface is abstract. It does not contain any specific implementation code, but only declares the protocol that must be followed to implement version control. In the present invention, the version interface includes the steps implemented by all database version classes. For example, define a database version interface, such as: DatabaseVersion.

[0064] The Version Class is a concrete implementation of the Version Interface. Each Version Class corresponds to a specific version number and implements all methods defined in the Version Interface. The Version Class contains the upgrade logic for a specific version number and the possible downgrade logic.

[0065] Specifically, each version class needs to implement the version interface and upgrade. Version is used to identify the database version, and upgrade is used to implement the upgrade behavior of this version of the database. For example, for version V1.0.1, it is necessary to add ROI (region of interest) settings for the EIT software, and a data table corresponding to ROI needs to be added to the database. The upgrade interface pseudocode implemented by the database class corresponding to version V1.0.1 is as follows: void upgrade(){database.addTable("create tableROI");}; V1.0.2 adds the need to record the electrical impedance of EIT at a certain moment, and it is necessary to add an impedance field to a data table. The upgrade interface pseudocode implemented by the database class corresponding to version V1.0.2 is as follows: void upgrade(){database.addField("Impedance")}; Arrange in ascending order by version (the interface requires the implementation of version to determine the version), and store these objects in a data structure that guarantees order.

[0066] For reference Figure 1B , Figure 1B The three versions of database version class objects are described in , all arranged in ascending order of version numbers.

[0067] Among them, the Version Class Instance is the instantiation result of the Version Class. Each object represents a specific version and contains all the information and logic of this version. When an upgrade or downgrade operation is required, a Version Class object is created and its methods are called.

[0068] Therefore, in the above description, the version interface is a template that specifies the methods that the version class should implement; the version class is the specific implementation of the version interface, and each class corresponds to a specific version number; the version class object is an instance of the version class, representing the operations and data of a specific version; the data structure is a container for the version class objects, responsible for organizing and managing these objects to ensure that they are executed in the correct order.

[0069] The target operation is the operation corresponding to a version number higher than the target version number, indicating the specific steps that need to be performed during the database upgrade process, such as adding a new table, modifying the table structure, inserting initial data, etc.

[0070] Wherein, in the specific implementation of traversing the data structure in the EIT device based on the target version number to obtain at least one target operation, the target operation is an operation corresponding to a version number higher than the target version number, based on the target version number, traversing the data structure to obtain all operations corresponding to version numbers higher than the target version number. These operations represent the steps required to upgrade the database from the current version to the target version.

[0071] Among them, the version class objects in the data structure are arranged in ascending order according to the version number, ensuring that the upgrade operation can be performed in sequence according to the version number during the traversal process. Arranging the version class objects in ascending order according to the version number can ensure that the upgrade operation is performed in sequence according to the version number during the traversal process, avoiding omission or duplication of certain operations.

[0072] Furthermore, starting from the current version number, the operations defined in each version class object higher than the current version number are executed in sequence until the operation corresponding to the highest version number in the data structure is reached.

[0073] It can be seen that in this embodiment, the consistency and correctness of the database upgrade are ensured according to the version number, and a structured method is provided to manage and execute complex upgrade tasks.

[0074] In one embodiment, querying the operation corresponding to the database version number based on the database version number includes: determining whether the database version number matches the version number of the version class object stored in the data structure; if so, obtaining the data structure in the EIT device, the data structure representing a set of version class objects stored in the EIT device, the arrangement order in the data structure being in ascending order according to the version numbers in the version class objects stored in the EIT device; wherein the version class object is a version class and a corresponding information set, the version class corresponds to a version number, the version class is used to implement a version interface, and the version interface includes all steps implemented by the database version class; determining the operation corresponding to the database version number based on the database version number and the data structure in the EIT device.

[0075] If the database version number matches the version number of a version class object in the data structure, it means that the database is already in the version state represented by the version class object. At this point, you need to prepare for possible further upgrade operations.

[0076] In the process of determining the operation corresponding to the database version number according to the database version number and the data structure in the EIT device, the first version class object with a version number higher than the current database version number in the data structure is searched, and the upgrade steps defined in the version class object are executed.

[0077] It ensures that the upgrade is performed along the correct path (order in the data structure), that is, starting from the current version number, the operations of each subsequent version class object are performed in sequence until the latest version number is reached.

[0078] For example, see Figure 1B ,exist Figure 1B The middle figure shows a collection of version database class objects. These objects are arranged from low to high by version number. Each version database class object represents a specific database version and the upgrade operation corresponding to that version. Compare the current database version number with the V1.0.1 version number. If the current database version number is higher than or equal to V1.0.1, skip the upgrade operation of this version. The figure shows the "skip" operation. Compare the current database version number with the V1.0.2 version number. If the current database version number is lower than V1.0.2, perform the upgrade operation of the V1.0.2 version. The figure shows the "execute upgrade" operation. Compare the current database version number with the V1.0.3 version number. If the current database version number is lower than V1.0.3, perform the upgrade operation of the V1.0.3 version. The figure shows the "execute upgrade" operation. Therefore, it can be guaranteed that the upgrade is not repeated or missed.

[0079] If the current database version number is higher than or equal to a certain version number, the upgrade operation of the version is skipped. If the current database version number is lower than a certain version number, the upgrade operation of the version is performed.

[0080] It can be seen that this embodiment ensures that the upgrade operation of the database is carried out in a planned, orderly and safe manner, thereby avoiding omissions or repeated operations during the version upgrade process.

[0081] In one embodiment, determining the operation corresponding to the database version number based on the database version number and the data structure in the EIT device includes: comparing the database version number with the version number in the data structure to determine that the database version number is in a first version class object corresponding to the data structure; in the data structure, obtaining a second version class object whose version number is higher than the first version class object; based on the second version class object, determining the version class corresponding to the second version class object; and based on the version class, determining a target operation, the target operation including all operations required to upgrade the database version number to the next version number.

[0082] Among them, through comparison, a version class object matching the current database version number is found, and this object is the "first version class object". It represents the current state of the database and the implemented upgrade operations.

[0083] Once the first version class object is determined, the next version number will continue to be searched in the data structure, that is, the first version class object with a version number higher than the current database version, which is the "second version class object".

[0084] Among them, the second version class object contains all the information required to upgrade to the next version, including the SQL script to be executed, data migration steps, configuration changes, etc. Use this information to determine the specific version class, that is, the specific class that implements the version interface.

[0085] The target operation refers to all operations required to upgrade the database from the current version number to the version number represented by the second version class object. These operations usually include: updating the database structure (for example, adding a new table, modifying the existing table structure, etc.); data migration or conversion to ensure the correctness and integrity of the data in the new structure; applying any necessary business logic changes or functional enhancements.

[0086] The upgrade operation must be performed in ascending order of the version numbers to ensure that the changes in each version can be applied correctly.

[0087] It can be seen that this embodiment ensures the consistency and correctness of the database upgrade, and at the same time provides a clear upgrade path from the current version to the next version.

[0088] In one embodiment, after determining the target operation according to the version class, the method further includes: upgrading the database in sequence according to the data structure until the version class object corresponding to the highest version number in the data structure is reached, and then stopping the upgrade.

[0089] Among them, the database is upgraded in sequence: according to the version class objects arranged in ascending order of version numbers in the data structure, the upgrade operations defined by each version class object are executed one by one. This process is incremental, that is, each time it is upgraded to the next version number. After executing the operation of a version class object, it is necessary to verify whether the upgrade is successful, including checking the database structure, data integrity and system functions.

[0090] Optionally, record detailed information for each upgrade, including version number, operations performed, execution time, results, etc., to facilitate tracking and auditing.

[0091] The upgrade process will continue until the last version class object in the data structure, that is, the version class object corresponding to the highest version number, is processed. This version class object represents the latest version of the database. That is, once the highest version number in the data structure is reached and the corresponding upgrade operation is performed, the upgrade process will stop. At this point, the database should have been updated to the latest version and include all necessary changes and new features.

[0092] It can be seen that this embodiment ensures that the database smoothly transitions from one version to another, eventually reaching the latest version state, while maintaining the stability of the database and the integrity of the data.

[0093] It should be noted that, in each of the above-mentioned embodiments, there is not necessarily a certain order between the above-mentioned steps. A person skilled in the art can understand, based on the description of the embodiments of the present application, that in different embodiments, the above-mentioned steps may have different execution orders, that is, they may be executed in parallel, may be executed interchangeably, and so on.

[0094] As another aspect of the embodiment of the present application, the embodiment of the present application provides an upgrade device based on an EIT device software database. The upgrade device based on the EIT device software database can be a software module, and the software module includes a number of instructions stored in a memory. The processor can access the memory and call the instructions for execution to complete the upgrade method based on the EIT device software database described in the above various embodiments.

[0095] See also Figure 2 , Figure 2 Schematic diagram of the structure of an upgrade device based on an EIT device software database provided in an embodiment of the present application. Figure 2 As shown, the upgrading device 200 based on the EIT device software database includes:

[0096] An acquisition unit 201 is used for acquiring a database version number of a current database of an EIT device, wherein the EIT device has a database upgrade function;

[0098] The upgrading unit 203 is used to upgrade the database of the EIT device according to the operation corresponding to the database version number.

[0099] By acquiring the database version number of the current database of the EIT device, the method can accurately manage the database version in the EIT device to ensure that each version of the database can be accurately identified and processed; according to the database version number, the corresponding upgrade operation is queried, and the database is upgraded according to these operations, which can realize the automatic upgrade process of the database, reduce manual intervention, and improve the upgrade efficiency; further, by querying the operation corresponding to the database version number, it can be ensured that each upgrade operation is based on the correct steps of the current database version, thereby reducing the risk of errors in the upgrade process and ensuring the stability and reliability of the database upgrade; further, corresponding operations can be performed according to different database version numbers, so that the EIT device can flexibly respond to different versions of the database and ensure the compatibility and scalability of the device. Therefore, the method can reduce the workload of maintenance personnel, reduce maintenance costs, and can quickly respond to the update requirements of the database version, thereby improving the maintenance efficiency of the device.

[0100] In one embodiment, before obtaining the database version number of the current database of the EIT device, the acquisition unit 201 is further used to: query whether there is a version field in the structure corresponding to the database in the EIT device, and the version field is used to record the version number of the current database; if the version field does not exist, add a target version field according to a preset operation, and the target version field indicates the starting version of the current database.

[0101] In one embodiment, in the step of obtaining the database version number of the current database of the EIT device, the obtaining unit 201 is further used to: query the corresponding version field in the current database of the EIT device; and determine the database version number of the current database according to the version field.
