[0057] In order to make the purpose, technical scheme and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

The process can be terminated when its operation is completed, but it can also have additional steps not included in the accompanying drawings. The process can correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.

[0058] The terminal replacement method, device, electronic device and storage medium of the cloud classroom provided by the present application are intended to obtain the old terminal information of the old terminal in the cloud classroom system through the seat number when replacing the terminal, so that the new terminal can obtain the historical information of the old terminal, avoid the information loss caused by the replacement of the terminal, and ensure the information integrity of the cloud classroom; and when adding a new terminal, when the old terminal information cannot be queried through the seat number, the seat number is set to the newly added seat number by default, so as to increase the association between the new terminal and the cloud classroom. Compared with the traditional cloud classroom terminal replacement method, it usually re-associates and reconfigures all resource information when replacing or adding a new terminal, resulting in the loss of the original terminal information and incomplete system information. Based on this, a terminal replacement method of the cloud classroom of the embodiment of the present application is provided to solve the problem of information loss caused by the replacement of student terminals in the existing cloud classroom.

[0059] Embodiment 1:

[0060] Figure 1 A flow chart of a terminal replacement method for a cloud classroom provided in the first embodiment of the present application is given. The terminal replacement method for a cloud classroom provided in this embodiment can be executed by a terminal replacement device for a cloud classroom. The terminal replacement device for the cloud classroom can be implemented by software and / or hardware. The terminal replacement device for the cloud classroom can be composed of two or more physical entities, or can be composed of one physical entity. Generally speaking, the terminal replacement device for the cloud classroom can be a terminal device, such as a computer, a mobile phone, or a tablet.

[0061] The following description is made by taking a computer as the main body of the terminal replacement method for executing the cloud classroom. Figure 1 , the terminal replacement method of the cloud classroom specifically includes:

[0062] S101. Receive new terminal information and old terminal information query instructions sent by the new terminal, wherein the new terminal information includes new terminal ID information, new terminal IP information, and seat number. The new terminal IP information includes IP information assigned by the DHCP relay server when the new terminal is turned on. The seat number is the seat number corresponding to the old terminal or a newly added seat number.

[0063] During the initialization phase of the cloud classroom, the number of IP addresses in the cloud classroom network segment is configured to be greater than or equal to N+1, where N represents the number of seats in the cloud classroom. When an old terminal needs to be replaced with a new terminal, or a new terminal needs to be added, the new terminal ID information is automatically generated after the new terminal is turned on and saved in the memory hard disk of the new terminal. The new terminal establishes communication with the DHCP relay server and obtains the new terminal IP information automatically assigned by the DHCP relay server.

[0064] Reference Figure 2 When an old terminal needs to be replaced with a new one, the new terminal will include the new terminal ID information, the new terminal IP information, the new terminal information of the seat number corresponding to the old terminal, and the old terminal information query instruction to the cloud classroom server. The cloud classroom server receives the new terminal information and the old terminal information query instruction. For example Figure 2 In the example, the old terminal corresponding to seat number 8 fails and needs to be replaced with a new terminal, and the corresponding seat number is still 8. The new terminal device with seat number 8 sends the corresponding new terminal ID information, new terminal IP information, seat number 8, and old terminal information query instruction to the cloud classroom server. The cloud classroom server receives the corresponding new terminal ID information, new terminal IP information, seat number 8, and old terminal information query instruction.

[0065] Reference Figure 3 When a new terminal needs to be added, the new terminal will include the new terminal ID information, the new terminal IP information, the new terminal information of the newly added seat number, and the old terminal information query instruction to the cloud classroom server. The cloud classroom server receives the new terminal information and the old terminal information query instruction. For example Figure 3 In the cloud classroom, when a student's seat needs to be added, a new terminal is added, and the new seat number is 19. The new terminal device with seat number 19 sends the corresponding new terminal ID information, new terminal IP information, seat number 19, and old terminal information query instruction to the cloud classroom server. The cloud classroom server receives the corresponding new terminal ID information, new terminal IP information, seat number 19, and old terminal information query instruction.

[0066] S102: Search the network segment where the new terminal IP information is located according to the old terminal information query instruction.

[0067] When an old terminal needs to be replaced with a new one, the old terminal information query is started according to the old terminal information query instruction, and the cloud classroom information corresponding to the old terminal must be known. Based on the association between different cloud classrooms and the corresponding terminal devices with existing seat numbers, the network segment information of the IP addresses of the cloud classrooms and the associated terminal devices is also associated, and both the old and new terminals have the same DHCP relay server to allocate IP information, so it is necessary to search the network segment where the IP information of the new terminal is located to find the corresponding associated cloud classroom.

[0068] For example, refer to Figure 2 When the new terminal with seat number 8 replaces the original old terminal, the old terminal information query is started according to the old terminal information query instruction. Based on the association between the old terminal device with seat number 8 and the corresponding cloud classroom, the network segment information of the IP addresses of the cloud classroom and the old terminal device with seat number 8 is also associated, and both the new and old terminals with seat number 8 have the same DHCP relay server to allocate IP information. Therefore, it is necessary to search the network segment where the IP information of the new terminal with seat number 8 is located to find the cloud classroom associated with the corresponding old terminal with seat number 8.

[0069] When a new terminal needs to be added, the old terminal information query is started according to the old terminal information query instruction, and the cloud classroom information corresponding to the old terminal must be known. Based on the association between different cloud classrooms and the corresponding terminal devices with existing seat numbers, the newly added terminal device needs to establish the first association with the cloud classroom. Because the IP network segment information of the cloud classroom and the associated terminal device is associated, in order to associate the newly added terminal with the cloud classroom, it is necessary to search the network segment where the IP information of the new terminal is located to match the associated cloud classroom corresponding to the network segment.

[0070] For example, refer to Figure 3 ,When a new terminal at seat 19 is added, because it is a new terminal device, it needs to match the associated cloud classroom. Therefore, it is necessary to search the network segment where the IP information of the new terminal is located to match the associated cloud classroom corresponding to the network segment.

[0071] S103. Determine the cloud classroom information associated with the network segment according to the network segment where the new terminal IP information is located.

[0072] When an old terminal needs to be replaced with a new one, the original old terminal has been associated with the corresponding cloud classroom, and both the old and new terminals have the same DHCP relay server to allocate IP information. Therefore, the cloud classroom information corresponding to the old terminal can be determined based on the network segment where the new terminal IP information is located.

[0073] For example, refer to Figure 2Because the IP network segment of the old terminal device with seat number 8 is associated with the corresponding cloud classroom, and both the new and old terminals with seat number 8 have the same DHCP relay server to allocate IP information, therefore, according to the IP information of the new terminal with seat number 8, the corresponding network segment can be searched, and the cloud classroom information associated with the old terminal device with seat number 8 can be determined according to the network segment.

[0074] When a new terminal needs to be added, the cloud classroom information to be associated with the network segment is determined based on the network segment where the new terminal IP information is located. Figure 3 , add a new terminal with seat number 19, and match the cloud classroom information to be associated with the corresponding network segment according to the network segment where the new terminal with seat number 19 is located.

[0075] S104: Search the cloud classroom information according to the seat number to see whether there is old terminal information.

[0076] When an old terminal needs to be replaced with a new one, the ID information, IP information and seat number information corresponding to the old terminal are associated and stored in the corresponding cloud classroom information system; according to the seat number corresponding to the original old terminal, the old terminal information associated with the seat number is searched. The old terminal information includes the old terminal ID information, the old terminal motherboard ID information, the old terminal IP information, the seat number and the class record information corresponding to the old terminal.

[0077] For example, refer to Figure 2 When an old terminal needs to be replaced with a new terminal, that is, when the new terminal with seat number 8 replaces the old terminal with seat number 8, the old terminal information with seat number 8 exists on the cloud classroom server. Therefore, the corresponding old terminal information can be searched according to the corresponding seat number.

[0078] When a new terminal needs to be added, its seat number is newly added. There is no associated old terminal information in the cloud classroom information system. Therefore, according to the newly added seat number, the result of searching whether there is old terminal information is that there is no old terminal information.

[0079] For example, refer to Figure 3 , a new terminal with seat number 19 is added. There is no associated old terminal information for seat number 19 in the cloud classroom information system. Therefore, the old terminal information cannot be searched based on the newly added seat number 19.

[0080] S105. If the old terminal information exists, the old terminal information is sent to the new terminal;

[0081] The old terminal information can be searched in the cloud classroom information according to the seat number, proving that a certain old terminal is replaced by a new terminal, and the old terminal information and the old terminal replacement pending confirmation instruction are sent to the new terminal. The new terminal receives the old terminal information and the old terminal replacement pending confirmation instruction, and if it is confirmed that a replacement is required, it sends a confirmation replacement old terminal instruction to the cloud classroom server. The cloud classroom server generates a terminal replacement record based on the confirmation replacement old terminal instruction received from the new terminal, and the terminal replacement record includes cloud classroom information, seat number information, old terminal ID information, old terminal motherboard ID information, new terminal ID information and new terminal IP information.

[0082] After receiving the old terminal information, the new terminal replaces the new terminal ID information in the new terminal memory hard disk with the old terminal ID information to obtain the replacement ID information, and replaces the IP information assigned by the DHCP relay server with the IP information in the old terminal network configuration to obtain the replacement IP information. After completing the above replacement, the new terminal will package the replacement ID information, replacement IP information and new terminal motherboard ID information into replacement success information and send it to the cloud classroom server. The cloud classroom server receives the replacement success information sent by the new terminal; based on the received replacement success information, the terminal replacement record is updated. Based on the replacement success information received from the new terminal, the old terminal motherboard ID information recorded in the old terminal information is updated to the new terminal motherboard ID information. Therefore, the updated replacement terminal replacement record includes cloud classroom information, seat number information, old terminal ID information, new terminal motherboard ID information and old terminal IP information.

[0083] S106. If the old terminal information does not exist, the seat number is set to a newly added seat number, and a successful setting result is fed back to the new terminal.

[0084] If no old terminal information can be found in the cloud classroom information according to the seat number, it proves that a new terminal has been added. In this case, the seat number is set to the newly added seat number, the new terminal information is saved, the new terminal information is associated with the cloud classroom information and the newly added seat number, the IP information of the new terminal is fixed to the network configuration, and the result of successful setting is fed back to the new terminal, wherein the new terminal information includes the new terminal ID information, the new terminal motherboard ID information and the new terminal IP information.

[0085] As mentioned above, the embodiment of the present application receives the old terminal query information instruction and the new terminal ID information, the new terminal IP information, and the seat number, searches for the network segment where the new terminal IP information is located, and determines the associated cloud classroom according to the network segment, and searches for the old terminal information according to the seat number in the associated cloud classroom. If the old terminal information is found in the search, the old terminal information is sent to the new terminal. If the old terminal information does not exist, the seat number is set to the newly added seat number and the setting success result is fed back to the new terminal. By adopting the above technical means, when the new terminal replaces the old terminal, the old terminal information in the cloud classroom system can be obtained through the seat number, so that the new terminal can obtain the historical information of the old terminal, avoid the information loss caused by the terminal replacement, and improve the information integrity of the cloud classroom; and when adding a new terminal, when the old terminal information cannot be queried through the seat number, the seat number can be set to the newly added seat number by default, so as to increase the association between the new terminal and the cloud classroom, improve the efficiency of establishing the association between the new terminal and the cloud classroom, and improve the interactive experience of the cloud classroom.
