[0002] With the rapid development of the Internet, real-time data interaction and multi-user collaborative operation have become an important direction in application development. Especially in the fields of remote work, online education, and social platforms, the ability to edit and interact with data in real time and by multiple people has become a core requirement. However, traditional real-time collaborative editing technologies often have problems such as data conflicts and synchronization delays, resulting in a poor user experience. In the field of multi-user collaborative editing, the most widely used current technology is data synchronization technology based on a central server. In this technology, all users' operations are first sent to the central server, which is responsible for processing these operations to ensure data consistency, and then synchronizing the final data state to all users' devices.

[0003] During actual use, the applicant found that: The main advantage of this method is that its structure is relatively simple and easy to manage and control. However, this centralized data synchronization technology also has its inherent defects. Since all operations need to be processed and synchronized through the central server, this leads to problems such as obvious operation delays or data desynchronization for users in case of network latency, server busyness, or server failures. Especially when a large number of users are editing online simultaneously, these problems may be magnified. Summary of the Invention

[0028] An embodiment of the present invention provides a multi-user collaborative editing method. The execution subject of the multi-user collaborative editing method may be the multi-user collaborative editing device provided by the embodiment of the present invention, or an intelligent terminal and a server integrated with the multi-user collaborative editing device, where the multi-user collaborative editing device may be implemented in a hardware or software manner.

[0029] Before describing the technical solutions of the present invention, relevant technical terms are briefly explained as follows:

[0030] OT: Operational Transformation, which is a real-time collaborative editing technology that allows multiple users to simultaneously edit a shared document in a network environment. The main principle of OT is to convert an operation into a form suitable for remote operations when performing a local operation. In this way, when multiple operations occur simultaneously, they can be correctly merged without causing conflicts.

[0031] CRDT: Conflict-free Replicated Data Type, which is a data structure for solving data synchronization problems in distributed systems. The core idea of CRDT is to ensure data consistency among all replicas without the need for complex operation transformation. CRDT has two main types: State-based CRDT and Operation-based CRDT.

[0032] In the context of the existing Internet technology, although the data synchronization technology based on a central server has brought convenience to multi-user collaborative editing, its inherent defects cannot be ignored. First of all, the centralized architecture makes the entire system vulnerable to single-point failures. Once the central server fails, the collaborative editing activities of all users may be suspended or interrupted. Secondly, since all data processing and synchronization operations rely on the central server, a large amount of data interaction and processing tasks may cause the server resources to be quickly exhausted, thus affecting the real-time editing experience of users. Especially during peak hours or when a large number of users are online simultaneously, data synchronization delays and conflicts may occur frequently. In addition, this centralized method may also lead to data security and privacy issues because all user data needs to pass through the central server.

[0033] Based on this, the embodiments of the present invention provide a new multi-user collaborative editing method, which solves the above problems by introducing an Operational Transformation based Real-time Data Type (ORDT) application component. ORDT allows real-time data synchronization in a distributed environment, effectively reducing the load on the central server and enhancing data consistency and integrity. In addition, this technical solution also optimizes the data synchronization mechanism, enabling a smooth collaborative editing experience even when a large number of users are editing online simultaneously.

[0034] Specifically, please refer to Figure 1 , Figure 1 which is the first process schematic diagram of the multi-user collaborative editing method provided by the embodiments of the present invention. The specific process of this multi-user collaborative editing method can be as follows:

[0035] 101. Obtain the editing operations of users for the target event in the local port.

[0036] 102. Convert the editing operations into operation logs and synchronize the operation logs to other ports in the distributed network.

[0037] From a technical perspective, the multi-user collaborative editing technology based on ORDT mainly relies on the principle of OT. This is an algorithm designed for distributed systems that can synchronize data in real time between different users or devices, ensuring data consistency and integrity.

[0038] The core of the multi-user collaborative editing technology based on ORDT lies in the application of operation transformation. This is an advanced synchronization algorithm designed for a distributed environment to ensure that data remains consistent and complete under high-concurrency editing.

[0039] In an embodiment of the present invention, each editing operation of a user, whether it is insertion, deletion, or replacement, is converted into a specific operation representation. These operation representations are added to a local operation queue, and at the same time, they are immediately applied to the user's editing interface to achieve zero-latency local feedback. That is, after converting the editing operation into an operation log, the method further includes: adding the operation log to the local operation queue, and applying the editing operation to the editing interface of the current user on the local port based on the local operation queue.

[0040] 103. When other ports receive the operation log, pause the operation queues of other ports.

[0041] 104. Control other ports to execute the editing content corresponding to the operation log, and resume the operation queue after the execution is completed.

[0042] In one embodiment, when multiple users edit the same data simultaneously, conflicts will inevitably occur. To solve this problem, the embodiment of the present invention adopts a parallel processing technology. Specifically, when a device receives the operation representation of other users, the device will first pause its own operation queue, and then apply the operation representation of other users received. By applying the conflict resolution algorithm of OT, it can be ensured that each operation is correctly applied regardless of the arrival order of these operations.

[0043] In one embodiment, the above-mentioned distributed networks can be connected through WebSocket and P2P networks to implement an efficient and low-latency data synchronization mechanism, ensuring that all users can see the same data state almost at the same time, further enhancing the fluency and real-time performance of collaborative editing.

[0044] In this embodiment, by combining ORDT with mainstream front-end frameworks, an efficient, stable, and modular collaborative editing solution is provided for developers. This means that whether it is document collaboration within an enterprise, real-time chat on an online platform, or collaborative assignment editing in the education field, this solution can provide a smooth and accurate data interaction experience.

[0045] Most importantly, this solution is not limited to text editing, and its implementation method supports various data types and structures, and can be widely applied from simple text, images to complex charts and interactive applications. Generally speaking, this technical solution provides a powerful, flexible, and scalable solution path for current and future real-time multi-user collaborative editing scenarios.

[0046] As described above, the multi-user collaborative editing method proposed by the embodiments of the present invention can obtain the editing operations of users on a target event in the local port, convert the editing operations into operation logs, and synchronize the operation logs to other ports in the distributed network. When other ports receive the operation logs, they pause their own operation queues, execute the editing content corresponding to the operation logs, and resume their own operation queues after the execution is completed. The solution provided by the embodiments of the present invention can synchronize data in real time in a distributed environment, effectively reducing the load on the central server and enhancing the consistency and integrity of the data.

[0047] The method described in the previous embodiments will be further described in detail below.

[0048] Please refer to Figure 2 , Figure 2 which is the second process schematic diagram of the multi-user collaborative editing method provided by the embodiments of the present invention. The method includes:

[0049] 201. Obtain the editing operations of users on a target event in the local port.

[0050] 202. Convert the editing operations into operation logs, and synchronize the operation logs to other ports in the distributed network.

[0051] 203. When other ports receive the operation logs, pause the operation queues of other ports.

[0052] Specifically, each editing operation of the user, whether it is an insertion, deletion, or replacement, is converted into a specific operation representation. When a device receives the operation representations of other users, the device first pauses its own operation queue and then applies the operations received from other users. By applying the conflict resolution algorithm of OT, it can be ensured that each operation is correctly applied regardless of the order in which these operations arrive.

[0053] 204. Detect whether there is a conflict between the editing content corresponding to the operation logs and the editing content in the current operation queue of other ports. If so, execute step 205; otherwise, execute step 206.

[0054] 205. Convert the editing content corresponding to the operation logs, and execute the converted editing content.

[0055] In one embodiment, by using a consistency algorithm, such as the OT algorithm, the user editing content is adjusted to generate consistent modification results on multiple clients. Among them, OT is a real-time collaborative editing technology that allows multiple users to edit a shared document simultaneously in a network environment. The main principle of OT is to convert the operation into a form that adapts to remote operations when performing local operations. In this way, when multiple operations occur simultaneously, they can be correctly merged without causing conflicts.

[0056] Specifically, the core of the OT algorithm is two transformation functions, such as transform(client_operation, server_operation) and transform(server_operation, client_operation). These two functions transform one operation into another, enabling the smooth merging of client and server operations. That is, the steps for transforming the edit content corresponding to the operation log may include: extracting two operation sequences corresponding to the conflicting edit content respectively, and transforming the two operation sequences into a target operation sequence that can be executed serially through the operation transformation algorithm.

[0057] For example, suppose there are two users, A and B, editing a document simultaneously. User A inserts the character 'a' into the document, while user B inserts the character 'b' at the same position. To correctly merge these two operations, the transformation function can be used to transform these operations into a form relative to each other's operations. In this way, the final document will contain the two characters 'ab' or 'ba' instead of conflicts. Among them, the order of the above characters 'a' and 'b' can be determined according to the order of receiving the insertion operations (chronological order) or the priorities of the users. For example, if the system is set to process according to the order of receiving the insertion operations, the character corresponding to the insertion operation received first will be ranked first. Another example is that if a user has higher editing permissions or priorities, the character inserted by them will also be ranked first.

[0058] Specifically, a transformation function, namely the transform function, can be defined first. This function takes two operations (clientOp and serverOp) as inputs. This function determines how to transform the client operation according to the position of the operation to adapt to the server operation, and then initializes the document as a string, defining the insertion operations of users A and B. Each insertion operation has a type (insert), an insertion position, and an inserted character. Use the transform function to process the insertion operation of user A. In this example, the insertion operation of user A is transformed into inserting the character 'a' between "hb", and the transformed operation is applied to the document. First, apply the insertion operation of user B, and then apply the transformed insertion operation of user A. That is, the above operation sequence includes the type, the insertion position, and the inserted symbol. The operation transformation algorithm includes the transformation function. The steps for transforming the two operation sequences into a target operation sequence that can be executed serially through the operation transformation algorithm may include: using the transformation function to perform transformation processing on the two operation sequences based on the type, the insertion position, and the inserted symbol to obtain a target operation sequence that can be executed serially.

[0059] In other embodiments, the CRDT can also be used to solve the data synchronization problem in a distributed system. For example, assume there are two users, A and B, editing a document simultaneously, with the initial content being "hello". User A inserts the character "a" after "h", and user B inserts the character "b" after "h". Specifically, when users A and B perform the insertion operation, the characters to be inserted are generated into new characters with identifiers. For example, when user A inserts "a", the identifier is 1; when user B inserts "b", the identifier is 2. Finally, the document will contain the following character sequence: h(0), a(1), b(2), e(3), l(4), l(5), o(6). In this way, regardless of the order of operations, the final document content will be "habello", that is, the inserted characters are sorted according to the size of the corresponding identifiers. That is to say, the step of converting the edit content corresponding to the operation log described above may include: setting corresponding identifiers for two conflicting edit contents respectively, and merging the two edit contents based on the identifiers.

[0060] 206. Control other ports to execute the edit content corresponding to the operation log.

[0061] 207. Restore the operation queue of other ports.

[0062] In one embodiment, considering that device failures or network interruptions may occur, the technical solution of the present invention can implement the data persistence function. Each operation data is saved to the local database to ensure that the data will not be lost under any circumstances. If any problem occurs, the user can easily restore the edit operation from the last known state. Specifically, after controlling the other ports to execute the edit content corresponding to the operation log, the method may further include: obtaining the start execution time and the insertion position information of the edit content, and saving the edit content to the database corresponding to the other ports based on the start execution time and the insertion position information. Due to the decentralized design and efficient data persistence mechanism, the technical solution of the present invention can still maintain a high degree of stability in the face of device failures or network interruptions.

[0063] This embodiment is based on the mainstream front-end framework and combines modular design, providing developers with extensive customization and extension capabilities. And the technical solution based on ORDT, due to its modular and reusable design, greatly reduces the development difficulty and cost.

[0064] As described above, the multi-user collaborative editing method proposed by the embodiments of the present invention can obtain the editing operations of users for a target event in a local port, convert the editing operations into operation logs, and synchronize the operation logs to other ports in a distributed network. When other ports receive the operation logs, they pause their own operation queues and detect whether the editing content corresponding to the operation logs conflicts with the editing content in the current operation queues of other ports. If so, the editing content corresponding to the operation logs is converted and the converted editing content is executed. If not, other ports are controlled to execute the editing content corresponding to the operation logs, and their own original operation queues are restored after the execution is completed. The solution provided by the embodiments of the present invention can synchronize data in real time in a distributed environment, effectively reducing the load on the central server and enhancing the consistency and integrity of the data.

[0065] To implement the above method, the embodiments of the present invention also provide a multi-user collaborative editing device, which can be specifically integrated in terminal devices such as mobile phones, tablet computers, etc.

[0069] A receiving unit 303, configured to pause the operation queue of the other port when the other port receives the operation logs;

[0070] A processing unit 304, configured to control the other port to execute the editing content corresponding to the operation logs and restore the operation queue after the execution is completed.

[0071] The multi-user collaborative editing device proposed by the embodiments of the present invention can obtain the editing operations of users for a target event in a local port, convert the editing operations into operation logs, and synchronize the operation logs to other ports in a distributed network. When other ports receive the operation logs, they pause their own operation queues, control other ports to execute the editing content corresponding to the operation logs, and restore their own operation queues after the execution is completed. The solution provided by the embodiments of the present invention can synchronize data in real time in a distributed environment, effectively reducing the load on the central server and enhancing the consistency and integrity of the data.

[0072] The embodiments of the present invention also provide a terminal, such asFigure 4 As shown in the figure, the terminal 400 may include a memory 401 and a processor 402. Among them, an application processing program is stored on the memory 401, and when the application processing program is executed by the processor 402, the steps of the multi-user collaborative editing method in this embodiment are implemented.

[0073] Specifically in this embodiment, the processor 402 in the terminal will, according to the following instructions, load the executable files corresponding to the processes of one or more applications into the memory 401, and the processor 402 will run the applications stored in the memory 401 to implement various functions:

[0079] As can be seen from the above, the terminal according to the embodiment of the present invention can obtain the editing operations of the user for the target event in the local port, convert the editing operations into operation logs, and synchronize the operation logs to other ports in the distributed network. When the other port receives the operation logs, it pauses the operation queue of the other port, controls the other port to execute the editing content corresponding to the operation logs, and resumes the operation queue after the execution is completed.
