Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The file archiving method provided by the application can be applied to the application environment shown in fig. 1. The client communicates with the server through the network. The client may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server may be implemented by an independent server or a server cluster formed by a plurality of servers.
The internal structure of the client or the server is shown in fig. 1a, and the processor in fig. 1a is used for providing computing and control capability. The memory includes a nonvolatile storage medium, an internal memory. The non-volatile storage medium stores an operating system, a computer program, and a database. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The database is used for storing relevant data of the file archiving process. The network interface is used for communicating with other external devices through network connection. The computer program is executed by a processor to implement a file archiving method.
In the prior art, the Digital Imaging and Communications in Medicine (DICOM) protocol does not support archiving of non-DICOM-formatted files. Even if we compress the file into the tag of the pixelta (pixel data) of a DICOM file for storage, that file will have a size of at least tens of G. C-type services such as C-Move and C-Store of DICOM transmit dozens of G large files with great risk of packet loss, and file transmission fails. Based on this, the embodiments of the present application provide a file archiving method, apparatus, computer device and storage medium, which can safely and reliably transmit a large-capacity heterogeneous file to be archived in a PACS. The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems by embodiments and with reference to the drawings. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that, in the file archiving method provided by the present application, the execution subject in fig. 2 to fig. 9 is a client, where the execution subject may also be a file archiving apparatus, and the apparatus may be implemented as part or all of the client by software, hardware, or a combination of software and hardware.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.
In one embodiment, as shown in fig. 2, a file Archiving method is provided, which is described by taking the application environment of fig. 1 as an example, wherein a Picture Archiving and Communication System (PACS) operates on the server side of fig. 1. The embodiment relates to a specific process that when a file to be transmitted comprises a heterogeneous file, a client transmits the heterogeneous file in the file to be transmitted and a file in a standard format by adopting different protocols; this embodiment comprises the steps of:
s101, receiving a file to be transmitted; the files to be transmitted comprise heterogeneous files, self-built standard format files of the heterogeneous files and original standard format files; the self-built standard format file comprises the check information of the heterogeneous file, and the check information of the heterogeneous file is the same as the check information of the associated file of the heterogeneous file in the original standard format file.
The heterogeneous file refers to a file with a different format structure from the standard format file, for example, the standard format file is in a DICOM format, and the heterogeneous file is a file in a non-DICOM format, and the format of the heterogeneous file may be a binary file such as ctr/. ecg/. hw/. nc/. raw/. resp/. sw. By way of example, the heterogeneous files in the embodiments of the present application include, but are not limited to, medical image data generated by nuclear magnetic, Computed Tomography (CT), ultrasound, various X-ray machines, various infrared machines, microscopy machines, and the like; or a file made by the medical staff.
The self-established standard format file of the heterogeneous file is a file which is established according to the heterogeneous file in the file to be transmitted and comprises part of information of the heterogeneous file, wherein the part of information of the heterogeneous file conforms to the standard format; the original standard format file refers to a file which is in a standard format in the files to be transmitted. And the original standard format file has an associated file which is relatively related to the content in the heterogeneous file.
Optionally, the self-built standard format file may include check information, sequence information, index information, file identification information, and the like of the heterogeneous file. The index information of the heterogeneous files in the self-established standard format file is also pre-established and is used as a retrieval basis for subsequently inquiring the heterogeneous files. The file identification information of the heterogeneous file refers to identification information of the heterogeneous file itself, for example, a file name, a file content keyword, a file type, and the like can reflect information of the file type itself, and the file identification information can identify that the corresponding heterogeneous file is a heterogeneous file.
Wherein, the sequence information comprises self-defined sequence information and also comprises the existing sequence information which is directly adopted; for example, for a diagnosis and treatment object, it can perform multiple examinations on a Study, one examination corresponds to one examination information (Study Instance UID), one examination Study can include sequences of multiple part detections, one sequence corresponds to one sequence information (Series Instance UID), and images of the same sequence refer to image files produced by the same equipment and belonging to the same diagnosis and treatment object and generated by the same examination; then if the associated file of the heterogeneous file in the original standard format file is associated with only one sequence of image files, the sequence information in the self-created standard format file can directly use the sequence information of the sequence of image files (e.g. Series instant UID: 0020,000E).
However, if the associated file in the original standard format file in the heterogeneous file is related to the image file of the entire inspection Study, the sequence information of the inspection Study (e.g., Study Instance UID: 0020,000D, or, the property ID (0010,0020)) may be used, and the inspection information of the heterogeneous file is the same as the inspection information (Study Instance UID) of the associated file in the original standard format file of the heterogeneous file; further, while the student Instance UID is adopted, a Series Instance UID can be customized below the student Instance UID to form different Sop Instance UIDs (upper and lower level object identifiers); specifically, the process of customizing the Series Instance UID may be to perform sequence classification on the heterogeneous files as needed, for example, to perform modal classification, if a batch of raw data is DICOM data for finally generating a CT modality, that is, standard format data, the batch of raw data may be divided into a sequence, the batch of raw data files are placed in a sequence, a unique Series Instance UID is created, and information such as the size or number of the batch of raw data or the identification of the heterogeneous data may be recorded.
No matter which establishing method of the sequence information is, the checking information of the heterogeneous file finally stored in the self-established standard format file needs to be the same as the checking information of the related file of the heterogeneous file in the original standard format file, so that the relationship between the heterogeneous file and the original standard format file is realized, and the subsequent inquiry of the archived heterogeneous file is facilitated.
The method for the client to receive the file to be transmitted includes, but is not limited to, uploading the file by a user on a client interface, transmitting the file to the client by other third-party equipment according to a request of the client or according to actual requirements, or automatically acquiring the file in a database of the client based on a preset program, and the like.
Taking the example that a user inputs a file to be transmitted on a client interface, the file system is a PACS system, in practical application, the file to be transmitted may not have a heterogeneous file, nor a self-established standard format file of the heterogeneous file, and for the user, the user wants to upload the file to be transmitted to the PACS system for archiving, therefore, a standard DICOM protocol is triggered when the user uploads the file to be transmitted to the client, and after receiving the file to be transmitted, the client can judge whether the file to be transmitted has the information such as the heterogeneous file, which standard format files are the self-established standard format files of the heterogeneous file, which standard format files are original standard format files, and after determining the information, file archiving is performed in a corresponding manner according to the following S102 and S103. Therefore, the file information to be transmitted is accurately identified in advance, resource waste caused by transmission errors is avoided, the file transmission efficiency is improved, and the file transmission reliability is also improved.
S102, uploading the self-built standard format file and the original standard format file to a file system through a standard protocol of the file system, and indicating the file system to file the self-built standard format file and the original standard format file.
Because the self-built standard format file and the original standard format file are both files conforming to the standard format, a standard protocol interface of a file system (operated at a server) can be directly called, and the self-built standard format file and the original standard format file are uploaded to the file system. Illustratively, the file system is a PACS system, the standard protocol interface of the PACS system is a DICOM protocol interface, the standard format is also a DICOM format, that is, the self-established standard format file and the original standard format file are both DICOM format files, and then the self-established standard format file and the original standard format file are uploaded to the PACS system by calling the DICOM protocol interface.
After uploading to the PACS system, the PACS system stores the files with the self-established standard format and the files with the original standard format to finish the archiving process.
S103, uploading the heterogeneous files to the file system through the heterogeneous special protocol of the file system, and indicating the file system to archive the heterogeneous files.
And for the heterogeneous files in the files to be transmitted, the client calls a heterogeneous special protocol of the file system to upload the heterogeneous files to the file system. The heterogeneous dedicated protocol refers to a protocol for uploading heterogeneous files with non-standard formats, for example, a transmission protocol such as Http protocol, TCP protocol, FTP protocol, and the like. For example, the client uploads the heterogeneous file to the PACS system through the Http protocol. The heterogeneous file is uploaded through the heterogeneous special protocol, risks such as packet loss and the like in the transmission process of the heterogeneous file are avoided, and the heterogeneous file can be safely and reliably uploaded to a PACS system to be archived.
In the file archiving method provided by this embodiment, after receiving a file to be transmitted, which includes a heterogeneous file, a self-created standard format file of the heterogeneous file, and an original standard format file, the self-created standard format file and the original standard format file are uploaded to a file system through a standard protocol of the file system, the file system is instructed to archive the self-created standard format file and the original standard format file, the heterogeneous file is uploaded to the file system through a heterogeneous dedicated protocol of the file system, and the file system is instructed to archive the heterogeneous file. The heterogeneous special protocol can avoid the problems of packet loss and the like of the heterogeneous files in the transmission process because the heterogeneous files are uploaded through the heterogeneous special protocol during uploading the files, so that the heterogeneous files can be safely and reliably uploaded to a PACS system for archiving. In addition, the self-built standard format file of the heterogeneous file comprises the check information of the heterogeneous file, and the check information of the heterogeneous file is the same as the check information of the associated file of the heterogeneous file in the original standard format file, so that the association between the heterogeneous file and the original standard format file is realized through the same check information, and the subsequent inquiry of the archived heterogeneous file is greatly facilitated.
In the uploading the heterogeneous file to the file system through the heterogeneous dedicated protocol of the file system, in order to further ensure the security and reliability of the uploading process, the heterogeneous file may be partitioned and signed, as shown in fig. 3, in an embodiment, the step S103 includes the following steps:
s201, obtaining the compressed heterogeneous file, blocking the compressed heterogeneous file and marking an identifier to obtain a blocked heterogeneous file of the heterogeneous file.
And compressing the heterogeneous file by adopting a preset compression algorithm to obtain the compressed heterogeneous file, wherein the compression algorithm is not limited, such as a Huffman algorithm and the like. After the compressed heterogeneous file is obtained, the compressed heterogeneous file is partitioned into blocks, which may be divided evenly or in a user-defined size, or may be directly compressed into small heterogeneous files during compression, and the like, which is not limited in this respect.
The Identifier is marked on the heterogeneous file of each block, and a digital Identifier is generated as a Globally Unique Identifier (GUID) on the heterogeneous file of each block through an algorithm, for example.
S202, after signing the blocked heterogeneous file, uploading the file to a file system through a heterogeneous special protocol of the file system.
Based on each blocked heterogeneous file marked with the identifier obtained in the above steps, each blocked heterogeneous file is signed, for example, by using MD5 hash algorithm, that is, a hash value is generated. And uploading the signed blocked heterogeneous file to a file system (PACS) through an http protocol (heterogeneous dedicated protocol).
For the PACS system, after receiving each block heterogeneous file, the PACS system can perform repeatability verification on each block heterogeneous file according to the signature, so that the repeated receiving of a certain block heterogeneous file and the integrity verification are avoided, and the loss of a certain block heterogeneous file in the transmission process is avoided, thereby ensuring the uniqueness and the integrity of the block heterogeneous file. In addition, in the embodiment, since the large-capacity heterogeneous file is compressed and partitioned and the Http protocol is used for file transmission, transmission controllable functions such as breakpoint continuous transmission and failure rollback can be supported, and the safety and reliability of heterogeneous file transmission are further improved.
For a client, when receiving a file to be transmitted, a self-established standard format file in the file to be transmitted needs to be established, so that before the client receives the file to be transmitted, a self-established standard format file establishing process of a heterogeneous file needs to be performed, as shown in fig. 4, an embodiment is provided for description, and the embodiment includes the following steps:
s301, obtaining the compressed heterogeneous file, and establishing index information for the compressed heterogeneous file.
Similarly, when the compressed heterogeneous file is to be obtained first, the compression algorithm is not limited. And then, index information is established for the compressed heterogeneous files, and the established index information can be stored by using a private Tag. For example, it may be created by a snowflake algorithm. The obtained index information is used as a retrieval basis for subsequently querying the heterogeneous files. In addition, a process of querying the heterogeneous file through the index information is specifically described in embodiments provided later, and reference may be made to the subsequent embodiments.
S302, file identification information of the heterogeneous files, sequence information of the heterogeneous files and checking information of associated files of the heterogeneous files in the original standard format files are obtained.
The identification information of the heterogeneous file can be information which can represent the file itself, such as a file name, a file content keyword, a file type and the like; the obtaining process may be that the client receives an input from a user, or the heterogeneous data content is automatically identified and then generated, which is not limited in this embodiment. The sequence information of the associated file of the heterogeneous file in the original standard format file refers to information such as a sequence identifier, a sequence number, and the like, and the inspection information of the associated file of the heterogeneous file in the original standard format file refers to inspection information Study identity UID that belongs to the same inspection as the associated file, where specific acquisition manners of the sequence information and the inspection information have been described in the embodiment of fig. 2, and may be referred to the above description, and are not described herein again.
And S303, storing the index information, the file identification information, the sequence information of the heterogeneous file and the check information into a self-built standard format file to obtain the self-built standard format file of the heterogeneous file.
After the index information, the file identification information, the sequence information and the check information of the heterogeneous file are obtained, the index information, the file identification information, the sequence information and the check information of the heterogeneous file are stored in a self-established standard format file, and the self-established standard format file of the heterogeneous file can be obtained, for example, the self-established standard format file needs to follow the DICOM standard to be a DICOM format file.
In this embodiment, taking the PACS system as an example, since the conventional PACS system does not support the archiving of heterogeneous files, it must be a file conforming to the DICOM protocol standard format to be parsed and stored, and the DICOM format file is usually not very large. Therefore, the DICOM protocol cannot be directly used for filing tasks, large-capacity heterogeneous files need to be converted into a DICOM format based on the need of filing, and meanwhile, the DICOM files are not suitable for being too large and cannot be stored as a Tag of the DICOM. Therefore, only the index information, the file identification information, the sequence information and the check information of the heterogeneous files are stored in the self-built standard format file, and the heterogeneous files are associated with the standard format file through the information, so that the self-built standard format file is stored only by adopting a standard protocol, the self-built standard format file can be further positioned by searching the self-built standard format file during query, and the heterogeneous files are ensured to be reliably filed in the PACS.
For the file system of the server, after receiving the heterogeneous file transmitted by the client, the file system stores the heterogeneous file, and the convenience of subsequent heterogeneous file query can be improved by recording the storage information of the heterogeneous file. In one embodiment, the process of archiving heterogeneous files by the file system includes: the file system stores the heterogeneous files by using object storage, and stores the incidence relation between the index information in the self-built standard format files of the heterogeneous files and the object storage indexes into a preset dictionary table.
Taking the PACS system as an example, after receiving the heterogeneous file, the PACS system checks the integrity and uniqueness of the received heterogeneous file and starts to store the heterogeneous file. In particular, the PACS system uses object storage to store heterogeneous files, which is efficient and convenient to manage compared to conventional storage disks. After storing the heterogeneous files, the PACS system establishes a dictionary table, and associates object storage indexes with index information of the heterogeneous files in the self-established standard format file in the dictionary table, wherein the object storage indexes can be regarded as indexes of actual position information of the heterogeneous files stored by the PACS system; therefore, the incidence relation between the index information of the heterogeneous file and the object storage index is established, the heterogeneous file can be positioned through the object storage index corresponding to the index information of the heterogeneous file, the follow-up query of the heterogeneous file is facilitated, and the query efficiency is improved.
An embodiment of the above-described file archiving process is provided, as shown in fig. 5, taking a specific PACS system as an example. The embodiment comprises the following steps:
and S11, compressing the large-capacity heterogeneous file.
And S12, establishing an index for the compressed file.
And S13, creating a self-built DICOM file, storing inspection information, indexes, sequence information, identification information and the like, and associating the inspection information with the related file in the original DICOM file.
S14, original DICOM file.
S15, standard DICOM protocol filing.
And S16, judging whether the heterogeneous data exist, if so, executing S18, and otherwise, executing S17.
S17, archiving the original DICOM file.
And S18, additionally adding an Http protocol to transmit the compressed heterogeneous file to the PACS.
After the self-built DICOM file and the original DICOM file are transmitted, the compressed heterogeneous file also needs to be transmitted to the PACS system.
S19, the PACS stores the heterogeneous file in the object storage, and stores the index and the index information in the self-established DICOM file in the associated object storage index of the dictionary table.
And S20, finishing archiving.
The implementation principle and technical effect of each step in the file archiving method provided in this embodiment are similar to those in the previous embodiments of the file archiving method, and are not described herein again. The implementation manner of each step in the embodiment of fig. 5 is only an example, and is not limited to this implementation manner, and the order of each step may be adjusted in practical application as long as the purpose of each step can be achieved. In the embodiment, the index of the high-capacity heterogeneous file is stored through the DICOM format file, so that the PACS can uniformly manage the heterogeneous file and the original DICOM file under the same check information or the same sequence information, meanwhile, the risk that the transmission of the high-capacity file by using a DICOM protocol fails is avoided, and the Http protocol is adopted to ensure the safe and reliable filing of the file to be transmitted.
After the files to be transmitted are filed, the most important application scene is the query scene, and for the convenience and the query efficiency of the query, corresponding improvements are made in the filing process of the heterogeneous files in the files to be transmitted, for example, the establishment of the index information of the heterogeneous files, the establishment of the association relationship between the index information of the heterogeneous files and the object storage index and the like can increase the convenience and the query efficiency of the query.
The following describes a document query process by way of a specific embodiment. As shown in fig. 6, in one embodiment, the method further comprises the steps of:
s401, receiving a query request; the query request carries the check information or sequence information of the file to be queried.
The query request received by the client may be a request input by a user in the client, and is used for requesting to query a file to be queried. Taking the PACS system as an example, the image in the PACS system that meets the condition may be a single attribute (for example, Patient ID or equipment type of PatientID) or a combination of multiple attributes (for example, PatientID and student identity UID), and the archived file can be queried through a standard service such as C-Find, that is, the same student identity UID and parent ID as the associated DICOM file. Therefore, the query request needs to carry inspection information or sequence information of the file to be queried, such as a Study Instance UID, a Series Instance UID, or may also be a parent ID, and the like, and the information can facilitate the client to accurately locate the file to be queried.
Taking the PACS system as an example, the query is a standard DICOM protocol query, such as C-Find, so that the query of a three-party system can be compatible, and all the systems conform to the DICOM standard protocol.
S402, in the file system, acquiring a standard format file corresponding to the check information or the sequence information; the corresponding standard format file comprises a self-built standard format file and an original standard format file.
And acquiring a corresponding standard format file in the file system according to the check information or the sequence information. In the file filing process, each file to be transmitted comprises a heterogeneous file, a self-established standard format file of the heterogeneous file and an original standard format file, namely the files conforming to the standard format comprise the self-established standard format file and the original standard format file, and in the storage process, the checking information of the heterogeneous file is the same as the checking information of the associated file of the heterogeneous file in the original standard format file. Therefore, in this step, the standard format file acquired by the client may be a self-created standard format file or an original standard format file.
It should be noted that, in practical application, the obtained corresponding standard format file may include a plurality of files, all of which may be self-built standard format files or original standard format files, or one part of which is a self-built standard format file and the other part of which is an original standard format file, which is not limited in this embodiment.
S403, if the corresponding standard format file is the self-built standard format file, analyzing the index information in the corresponding standard format file.
If the corresponding standard format file acquired by the client is the self-built standard format file, the index information of the heterogeneous file is definitely present in the standard format file, and therefore the client can analyze the corresponding standard format file to obtain the index information of the heterogeneous file.
S404, according to the index information, obtaining a heterogeneous file corresponding to the index information in the file system.
Based on the analyzed index information, the client acquires a heterogeneous file corresponding to the index information from the file system. For example, after the index information is obtained, the file system queries and obtains the heterogeneous file through the private protocol (i.e., the heterogeneous dedicated protocol), and since the file system is used by other third-party systems through the private protocol, the file system can obtain the heterogeneous file without affecting the document obtaining process of the standard DICOM protocol.
Optionally, an embodiment of obtaining a heterogeneous file corresponding to the index information is provided, and as shown in fig. 7, the embodiment includes the following steps:
s501, transmitting the index information to a file system through a heterogeneous special protocol, and indicating the file system to inquire a corresponding object storage index in a dictionary table; the dictionary table comprises corresponding incidence relation between the index information of the heterogeneous file and the object storage index of the heterogeneous file.
And S502, acquiring a heterogeneous file corresponding to the index information according to the object storage index.
Taking the PACS system as an example, the client calls a heterogeneous dedicated protocol interface of the PACS system, and transmits the analyzed index information to the PACS system. In the PACS system, the dictionary table comprises the corresponding association relationship between the index information of the heterogeneous files and the object storage indexes of the heterogeneous files, so the PACS system can inquire the object storage indexes corresponding to the index information in the dictionary table. The object storage index can be regarded as an index of actual position information of the heterogeneous file stored by the PACS system, so that the heterogeneous file can be accurately positioned through the object storage index, and the heterogeneous file corresponding to the index information is obtained. The PACS system returns the acquired heterogeneous file to the client, so that the user can check the file conveniently. The PACS system returns heterogeneous files to the client in a manner of using a heterogeneous proprietary protocol for transmission.
In the file archiving method provided by the embodiment, in the query process, the object storage index of the heterogeneous file is first located based on the index information of the file to be queried, and then the heterogeneous file is obtained according to the object storage index.
Of course, after the corresponding standard format file is initially located according to the check information or the sequence information, before parsing the index information in the standard format file, the client needs to determine whether the corresponding standard format file is a self-created standard format file or an original standard format file, specifically, as shown in fig. 8, in an embodiment, the method further includes:
s601, determining whether the corresponding standard format file is a self-built standard format file or an original standard format file according to the file identification information.
S602, if the corresponding standard format file is the self-built standard format file, executing the step of analyzing the index information in the corresponding standard format file; if the corresponding standard format file is the original standard format file, returning the corresponding standard format file.
The embodiment is based on the premise that the corresponding standard format file includes the file identification information, that is, the client needs to identify whether the corresponding standard format file is a self-created standard format file or an original standard format file, and the corresponding standard format file includes the file identification information. The file identification information can reflect the content of the file such as the type, the name and the like, and the file can be determined to be a heterogeneous file or a standard format file based on the information, if the file is the heterogeneous file, the corresponding standard format file can be determined to be a self-established standard format file, but if the file is determined to be the standard format file based on the file identification information, the corresponding standard format file can be determined to be an original standard format file.
If the corresponding standard format file is the self-built standard format file, the step of analyzing the index information in the corresponding standard format file is executed. If the corresponding standard format file is the original standard format file, the client directly returns the acquired corresponding standard format file.
And aiming at the fact that one part of the obtained files corresponding to the standard format is the self-built standard format file, the other part of the obtained files corresponding to the standard format is the original standard format file, and the corresponding file inquiring process can be executed according to the type corresponding to the files corresponding to the standard format. The heterogeneous files or the original standard format files returned by the PACS are inquired files to be inquired and displayed on a front-end interface, so that the client can check the files conveniently.
In this embodiment, the corresponding standard format file identified and obtained by the file identification information is a self-created standard format file or an original standard format file, and then the file to be queried is returned by adopting a corresponding query mode, and the query process is based on the information in the storage process, so that the query result is more accurate, and the query efficiency can be greatly improved.
As shown in fig. 9, an embodiment of the above file query process is provided by taking a specific PACS system as an example. The embodiment comprises the following steps:
and S21, after receiving the checking information or the sequence information of the file to be inquired, inquiring the PACS system through the DICOM protocol.
S22, obtaining the corresponding DICOM file of the checking information or the sequence information returned by the PACS.
And S23, identifying the file identification information.
S24, if the heterogeneous data is needed, executing S25, otherwise executing S29.
And S25, analyzing the corresponding DICOM file of the inspection information or the sequence information to acquire large-capacity heterogeneous data index information.
And S26, calling an Http interface of the PACS, and transmitting the index information as a parameter.
S27, the PACS service receives the parameter, and finds the object storage index corresponding to the index information through the dictionary table.
And S28, acquiring the heterogeneous data file according to the object storage index and returning the heterogeneous data file to the client.
And S29, finishing the acquisition.
The implementation principle and technical effect of each step in the file archiving method provided in this embodiment are similar to those in the previous embodiments of the file archiving method, and are not described herein again. The implementation manner of each step in the embodiment of fig. 9 is only an example, and is not limited to this, and the order of each step may be adjusted in practical application as long as the purpose of each step can be achieved.
