Fig. 3 is a schematic flowchart of a vector data processing method applied to a client according to an embodiment of the present invention, and please refer to fig. 3, where the method is applied to a client, and a plurality of clients are respectively in communication connection with a server, and the method includes:

s110: and after the vector data is modified, sending a data synchronization request to the server, wherein the data synchronization request carries the current vector data version information.

It should be noted that the vector data is a vector value applied in mapping engineering, and may include: vector data such as vector name, vector size, vector direction and the like, and the specific data type can be selected according to the actual requirements in the mapping process, which is not limited herein. In addition, in the client, the vector data may be stored preferably in the form of a data file. The data synchronization request may be a type of communication signal for requesting data synchronization from the server.

The current vector data version information may be information of a state record, and when the vector data is modified, the current vector data version information may be updated in a state, for example, the current vector data version information is nth version, and when the vector data is modified, the current vector data version information is updated in n +1 th version. The current vector data version information can be recorded in the client in a file form, and when the client sends a data synchronization request to the server, the data synchronization request can be sent to the server together with the current vector data version information.

S120: and receiving server vector data version information sent by the server according to the data synchronization request.

The server vector data version information is vector data version information of corresponding vector data stored in the server, is similar to current vector data version information stored in the client and is state record information, and after the server receives the data synchronization request and the current vector version data, the server can send the vector data version information of the corresponding vector data to the client sending the data synchronization request.

S130: and if the version information of the current vector data is the same as the version information of the vector data of the server, sending the modified vector data to the server and updating the version information of the current vector data.

It should be noted that, two pieces of state information, that is, the current vector data version information and the server vector data version information, are compared, and if the two pieces of state information are the same, that is, the current vector data version information and the server vector data version information are both n-th versions, modified vector data may be sent to the server, that is, a data file with the modified vector data is sent to the server, so that the vector data of the server is updated to the data file of the modified vector data. Meanwhile, the version information of the current vector data can be updated, that is, the nth version is updated to the (n + 1) th version.

For example, if the vector data of one client is modified, the client may send a data synchronization request to the server, the server sends the version information of the vector data of the server to the client according to the data synchronization request, the client compares the two version information, if the two version information are the same, the modified vector data may be sent to the server, the server may update the vector data of the server to the modified vector data, and the client may update the version information of the current vector data.

Fig. 4 is a schematic flow chart of updating vector data information at a client according to an embodiment of the present invention, please refer to fig. 4, S120: after receiving the server vector data version information sent by the server according to the data synchronization request, the method further comprises the following steps:

s121: and if the current vector data version information is different from the server vector data version information, sending a data request to the server.

It should be noted that, in the same manner as the comparison in S130, the two pieces of state information, i.e., the current vector data version information and the server vector data version information, are compared, and if the two pieces of state information are different, which indicates that the two pieces of state information are not synchronous with the server data, a data request may be sent to the server to request the server to send synchronous data, that is, data synchronization is completed with the server first.

S122: and receiving synchronous data sent by the server according to the data request.

It should be noted that, after receiving the data request, the server may send the server vector data to the corresponding client, and the client uses the received data as the synchronization data.

S123: and completing synchronization with the server according to the synchronization data, and updating that the version information of the current vector data is the same as the version information of the server vector data.

It should be noted that, after receiving the synchronization data, the client may use the server vector data as the current server vector data to complete synchronization. Meanwhile, the server vector data version information may be used as the current vector data version information, so that the current vector data version information is the same as the server vector data version information.

Illustratively, the version information of the current vector data of one client is nth version, the version information of the vector data of the server is nth +1 version, and the version information of the two versions are different, the client sends a data request to the server, the server sends the vector data of the server to the client according to the data request, at this time, the modification made by the client is not recorded, but the vector data of the server sent by the server is directly used as the current vector data, namely, synchronous data, which is equivalent to replacing a data file corresponding to the current vector data recorded in the client with a data file corresponding to the vector data of the server, and meanwhile, the version information of the current vector data is updated to nth +1 version to complete the update.

According to the vector data processing method provided by the embodiment of the invention, if the version information of the vector data of the server is different from the version information of the current vector data, synchronous processing is carried out, so that the problem of data conflict in the data interaction process of the server and the client is solved, and the overall working efficiency is improved.

After synchronization is complete, the client may send the modified data to the server so that the server is also synchronized with the client.

Optionally, in an embodiment provided by the present invention, if the client is disconnected from the server, the method further includes:

and after the modification vector data are modified, recording modification information into the modification record table.

It should be noted that the disconnection between the client and the server may be active disconnection or passive disconnection, where the active disconnection refers to disconnection between the client and the server under the operation control of a worker; the passive disconnection refers to disconnection between the client and the server due to offline conditions such as disconnection caused by unknown factors such as networks and equipment. When the disconnection between the client and the server is detected, the client can enter an off-line mode, data interaction is not performed between the client and the server in the off-line mode, and after the data of the client is modified, the modification information can be recorded into a modification record table, and the modification record table can enable a file list stored in the client to represent modification information such as the modification time, the modification content, the modification quantity, a modifier and the like of the record.

Fig. 5 is a schematic flow chart of updating version information of vector data according to a modified record table according to an embodiment of the present invention, please refer to fig. 5, where after modified vector data is modified, the method further includes the following steps:

s140: and after the client establishes communication with the server, starting an online editing mode.

In the off-line process, the modification of the data by the client side may cause the data difference between the client side and the server side to be larger, and after reconnection, the synchronization can be completed through an on-line editing mode.

Optionally, in the process that the client enters the "offline mode", if the client and the server reestablish a communication connection, the online editing mode may be started, where the online editing mode refers to that the client may obtain modification information of the server vector data in the process that the client is in the "offline state", and perform online editing on the modification information and information recorded in the modification record table of the client.

S150: and displaying the conflict data according to the modified data in the modified record table and the current data of the server based on the online editing mode.

It should be noted that, in the online editing mode, the modification information in the modification record table and the modification information in the vector data of the server may be compared to display the conflict data therein, where the conflict data refers to that a certain item of data exists and is different in the vector data modification information of the server and the modification information in the modification record table at the same time, that is, in the previous "offline mode", the item of data may be changed in both the server and the client.

S160: and responding to selection operation of the user based on the conflict data, completing data synchronization according to a selection result, and updating the version information of the current vector data.

It should be noted that, in the online editing mode, the user can clearly see the difference between the data of the client and the data of the server through the client, and the user can directly perform selection at the client, that is, select the data of the client or the server as the final synchronization data. The client can adopt the final synchronous data to complete synchronization according to the selection operation performed by the user, and correspondingly updates the version information of the current vector data after the synchronization is completed.

For example, after a client finishes an "offline mode", an online editing mode may be performed on the client, if version information of vector data of the client is n, and a modification comparison table of the client has modification information of a item of data, and modification information of a item of data also exists in modification information of a server, conflict data is generated about the a item of data, and according to a selection operation of a user, modification information that is relatively more required by the user may be used as data synchronization information, and current vector data in the client is changed to modification information of a selected one of the a items of data, and simultaneously version information of current vector data of the client is updated to n + 1.
