[0055] In the present application, the terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual quantity, primary and secondary or order relationship between the entities or operations.

[0056] In the present application, without more limitation, the "includes", "contains", "has" or other similar open expressions used in the sentence are intended to cover non-exclusive inclusion, and these expressions do not exclude the presence of other elements in the process, method or product including the described elements, so that the process, method or product including a series of elements can not only include those limited elements, but also include other elements not explicitly listed, or also include the elements inherent to such process, method or product.

For those skilled in the art of the present application, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0060] In the related art, in order to ensure the consistency of data in the local area network, the local area network usually adopts a master-slave mode, and the master terminal in the local area network performs centralized processing such as storage and access of each data. However, the master-slave mode will cause the data processing pressure of the master terminal to be large, the memory requirement to be high, and the master terminal to be easily interrupted due to memory overrun.

[0061] Therefore, to solve the above problems, the present embodiment provides a terminal data sharing method in a local area network, which optimizes the communication pressure and memory occupation of the master terminal, and avoids the termination of the service program due to the memory overrun of the master terminal. In this method, the master terminal and the slave terminal in the local area network both establish an Http server and a database, wherein the database of the master terminal is the master database, and the database of the slave terminal is the slave database; each terminal generates business data, and the business data is written into the master database by the master terminal and is synchronized to each slave terminal by the master terminal through the Http service, and is stored in the corresponding slave database by each slave terminal. Therefore, not only the consistency of the data can be ensured, but also each terminal can perform data query and other operations by accessing its local database, greatly reducing the communication pressure of the local area network and the memory consumption of each slave terminal in the business processing flow, and improving the stability of the local area network.

[0062] Please refer to Figure 1The embodiment provides a terminal data sharing method in a local area network.

[0063] S101, configuration information of each terminal in the local area network is set, the configuration information comprising an IP address of the terminal and a terminal type, the terminal type comprising a master terminal and a slave terminal;

[0064] S102, each terminal creates an Http server;

[0065] S103, the master terminal establishes a communication connection with the slave terminal;

[0066] S104, the slave terminal generates service data and transmits the service data to the master terminal through the local area network;

[0067] S105, the master terminal writes the received service data into a master database of the master terminal, and sends the service data successfully written into the master database to all slave terminals in the local area network;

[0068] S106, the slave terminal updates a local slave database according to the service data.

[0069] For example, service data submitted by a slave terminal A to a master terminal is a personnel information, comprising a personnel account and a personnel name. When the service data is submitted to the master terminal, the master terminal creates a new primary key according to a personnel table information primary key in a current master database to record the personnel information. After the personnel information: ID primary key, personnel account and personnel name are written into the master database successfully, all slave terminals are informed to write the personnel information into local databases through a protocol. Finally, the master-slave data consistency is ensured. The unique data (i.e. the ID primary key) must be managed by the master terminal.

[0070] In the embodiment, the local area network can be a multi-terminal local area network built by an Android system, i.e. each terminal in the local area network is an Android operating system terminal, and the Android operating system terminal comprises an Android mobile phone, an Android tablet computer, an Android smart bracelet and the like.

[0071] In the embodiment, each terminal in the local area network creates an Http server and is provided with a database, service processing can be generated and stored in each terminal, the master terminal is mainly responsible for synchronization of internal data in the local area network, all data access, query and other operations do not need to be processed by the master terminal, each slave terminal shares memory consumption generated in a service processing flow and resources occupied by slave terminal Http query, so that the memory requirement of the master terminal is reduced, the problem of memory occupation exceeding a limit and being terminated is reduced, and the stability of the local area network operation is improved.

[0072] In step S101, the configuration information is used to configure the local area network. The IP address of the terminal is also called an intranet IP address. The terminals in the local area network can access the Internet through a public gateway by using a NAT (Network Address Translation) protocol. Therefore, the terminals in the local area network can send a connection request to other devices on the Internet by using the IP address. The terminal type includes a master terminal and a slave terminal. More than one master terminal can be set in a local area network, and other terminals are slave terminals. The master terminal and the slave terminal are relatively functional in the local area network. They can be the same in hardware. The master terminal and the slave terminal can communicate in the local area network. The master terminal is mainly responsible for the transmission of business data in the local area network and the consistency of business data of the slave terminals in the local area network. When the configuration is performed, the master terminal needs to configure the communication address of each slave terminal, and each slave terminal needs to configure the communication address of the master terminal. Since each terminal in the local area network is provided with a database, in some embodiments, the configuration information further includes the database, specifically, the name, access address, database type and the like of the database. The database of the master terminal is a master database, and the database of the slave terminal is a slave database. The master database and the slave database can be the same type of database. In this embodiment, the master terminal synchronizes the business data to each slave terminal. Therefore, the business data stored in the slave database of each slave terminal is the same as the business data stored in the master database. Of course, the present application does not exclude that other data is stored in the master database in addition to the slave database.

[0073] In step S102, each terminal (including the master terminal and the slave terminal) in the local area network establishes an Http server. Http refers to Hypertext Transfer Protocol (HTTP). Http is a simple request-response protocol. The Http server refers to a server that implements the Hypertext Transfer Protocol. That is, each terminal in the local area network is provided with a Hypertext Transfer Protocol service program. Therefore, the Http server can realize the communication connection between the master terminal and the slave terminal, and the operation of business data query. As shown in FIG. 2, in an embodiment, the step of creating the Http server by each terminal includes: Figure 2

[0074] S201, each terminal creates a terminal service program, and mounts a service on the terminal service program;

[0075] S202, a communication port and an IP address of each terminal are set;

[0076] S203, an Http server is started in the service.

[0077] ​In the embodiment, the terminal can create a terminal service program, mount a background service through the Service mode of the Android system, and then start the Http server in the service. In the embodiment, the AndServer can be used to build the Http server, and the communication port and IP address of the terminal are set, and then the Http server is started.

[0078] In step S103, the master terminal and the slave terminals start the Http server, establish the LAN connection, and ensure the normal communication between the master terminal and the slave terminals. In other embodiments, the master terminal and the slave terminals in the LAN can use the TcpSocket service, and establish the LAN connection between the master terminal and the slave terminals through the Http Api interface or the Socket transmission protocol, to ensure the normal communication between the master terminal and the slave terminals.

[0079] In step S104, the slave terminals verify the final business data, and upload the business data to the master terminal. The slave terminal can submit the business data to be added to the master database to the master terminal through the Http Api interface or the socket transmission protocol. In some embodiments, if the business data is generated by the master terminal, the business data does not need to be uploaded, and is directly updated to the slave terminals by the master terminal through steps S105 and S106.

[0080] In step S105, in order to manage the business data in the LAN and verify the authenticity of the business data, the master terminal performs the uniqueness verification on the business data after receiving the business data, adds the uniqueness identifier, and then writes the business data into the database. In some embodiments, before the master terminal writes the received business data into the master database of the master terminal, the master terminal further performs the following steps: verifying the uniqueness of the business data, and assigning the unique identifier to the business data that passes the uniqueness verification.

[0081] Specifically, as shown in FIG. 4, the master terminal receiving the business data sent by the slave terminal and writing the business data into the master database includes the following steps: Figure 3

[0082] S301, the slave terminal generates the business data, and transmits the business data to the master terminal through the LAN;

[0083] S302, the master terminal verifies the uniqueness of the business data; if the uniqueness verification fails, the process jumps to step S303; if the uniqueness verification passes, the process jumps to step S304;

[0084] S303, the uniqueness verification failure is returned to the slave terminal, and the business data is discarded, that is, the business data is not written into the master database; ​

[0085] S304, assigning a unique identifier to the service data verified to be passed, each piece of service data in the local area network has a unique identifier, which is equivalent to the identity card number of the service data, and is used to distinguish other service data.

[0086] S305, writing the received service data into the main database.

[0087] In some embodiments, after the slave terminal updates the local slave database according to the service data, the method further comprises the steps of:

[0088] The master terminal sends control parameters for refreshing the database to each slave terminal.

[0089] After receiving the control parameters, the slave terminal updates the received service data on the display interface of the slave terminal. Therefore, through the embodiment, the service data can be transmitted and updated to the interface of the slave terminal in a timely manner.

[0090] In some embodiments, after the master terminal sends the service data to all slave terminals in the local area network, the method further comprises the steps of:

[0091] The master terminal controls the slave terminal to transmit the service data to multiple different application programs in the slave terminal through an Android Interface Definition Language (AIDL).

[0092] In some embodiments, the terminal data sharing method in the local area network further comprises the steps of:

[0093] When receiving the query data instruction, the slave terminal accesses the slave database locally to retrieve data.

[0094] In the above embodiments, the data stored in the slave database (i.e. the local database of the slave terminal) of each slave terminal is consistent with the main database (the main database may also store other additional data), so data retrieval can be directly performed according to the local slave database, without the need for data retrieval through the master terminal, thereby greatly reducing the occupation of communication resources of the local area network by data retrieval and other operations.

[0095] In some embodiments, the configuration information further comprises database information, and the slave database is a mobile database; the method further comprises the steps of:

[0096] The slave terminal accesses the main database and downloads the service data in the main database to the slave database of the slave terminal through FTP.

[0097] The mobile database is a database using mobile data technology. For example, in the embodiment, the database uses Realm mobile database technology, each database is a realm file, and the master terminal database file can be downloaded from the terminal through FTP (file transfer protocol) technology, so that the slave terminal can manually synchronize data.

[0098] As shown in Figure 4 In another embodiment, a terminal data sharing device 400 in a local area network is provided. The terminal data sharing device 400 in the local area network includes a configuration module 401, a communication module 402, a service generation module 403, a master processing module 404, and a slave processing module 405.

[0099] The configuration module 401 is configured to set the configuration information of each terminal in the local area network, and the configuration information includes the IP of the terminal and the type of the terminal, and the type of the terminal includes the master terminal and the slave terminal.

[0100] The communication module 402 is configured to create an Http server for each terminal, and establish a communication connection between the master terminal and the slave terminal.

[0101] The service generation module 403 is configured to generate service data by the slave terminal, and transmit the service data to the master terminal through the local area network.

[0102] The master processing module 404 is configured to write the received service data into the master database of the master terminal, and send the service data successfully written into the master database to all slave terminals in the local area network.

[0103] The slave processing module 405 is configured to control the slave terminal to update the local slave database according to the service data.

[0104] As shown in Figure 5 In another embodiment, a computer readable storage medium 500 is provided, and the computer readable storage medium 500 stores a computer program. When the computer program is run by a processor, the computer program performs the terminal data sharing method in the local area network in any one of the above embodiments.
