[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0028] Figure 1 Flowchart of an information synchronization method provided by an embodiment of the present invention. The information synchronization method provided by the embodiments of the present application is applicable to the situation of synchronizing the information in the personnel database between the first terminal and the second terminal. Typically, the embodiments of the present application are applicable to the situation of two-way information synchronization between the attendance management client and the access control device. This method can be specifically executed by an information synchronization device, which can be implemented in a software and / or hardware manner, and this device can be integrated in an electronic device capable of implementing the information synchronization method. Refer to Figure 1 , the method of the embodiments of the present application specifically includes:

[0029] S110. Obtain the first personnel database verification information of the first terminal and the second personnel database verification information of the second terminal.

[0030] The embodiments of the present application can be executed by an Agent scheduling system. The Agent scheduling system can be configured in the attendance management client. The Agent performs data caching, schedules the synchronization direction and synchronization content, and efficiently synchronizes information. Through the Agent, the business of the attendance management client and the access control device is separated, enhancing the business processing ability of the attendance management client. Among them, the first terminal can be the attendance management client, and the second terminal can be the access control device. It can also be configured that the first terminal is the access control device and the second terminal is the attendance management client. The first personnel database verification information in the first terminal and the second personnel database verification information in the second terminal can be represented in the form of a graph or in the form of a table. In the embodiments of the present application, the specific implementation solution is described by taking the form of a table as an example.

[0031] In the embodiments of the present application, as Figure 2 shown, a personnel database is established in the attendance management client and the access control device, and the personnel database information is as Figure 3As shown in the figure, the personnel database includes a personnel database identifier, a personnel identifier, personnel text information, a hash value of the personnel text information, a personnel image, and a hash value of the personnel image. The personnel database identifier and the personnel identifier are unique personnel identifier fields created by the access control device. When adding a new person or library permission to the access control device on the attendance management client, after the access control device successfully adds the permission, it will return the personnel database identifier + personnel identifier or the personnel database identifier of the newly added person to the attendance management client. The attendance management client then updates its own personnel database based on the returned personnel database identifier, personnel identifier, and other information, which can ensure the consistency of the personnel database identifier and the personnel identifier of the same person in both the left and right databases. The personnel text information includes information such as the person's name, gender, affiliated department, ID number, work card number, and address. The hash value of the personnel text information is generated by performing a hash calculation on the personnel text information based on a hash algorithm, and the hash value of the personnel image is generated by performing a hash calculation on the personnel image based on a hash algorithm. The hash algorithm is an algorithm that uses a shorter piece of information to ensure the uniqueness of a file. This identifier is related to every byte of the file. When the original file changes, its identifier value also changes. Therefore, if the personnel text information is different, the hash value of the personnel text information is also different, and if the personnel image is different, the hash value of the personnel image is also different.

[0032] In the embodiment of the present application, the personnel database verification information is not all the information in the personnel database of the terminal, but a part of the information extracted from the personnel database as verification information, including the personnel database identifier, the personnel identifier, the personnel text information, the hash value of the personnel text information, and the hash value of the personnel image, without extracting the personnel image. The beneficial effect of the above solution is that the file size of the personnel image is often large, which will consume transmission resources and storage resources, and when performing personnel image comparison, it will occupy computing resources and affect the computing speed. Therefore, information with a large file size such as the personnel image is not used as verification information, and information with a small data size is used as verification information, thereby improving the transmission efficiency and computing speed, increasing the speed of verification information comparison, and further improving the efficiency of information synchronization. Table 1 and Table 2 exemplarily show the first personnel database verification information table of the attendance management client and the second personnel database verification information table of the access control device. Among them, NULL indicates that the corresponding verification information does not exist. The existence and non-existence of the verification information in Table 1 and Table 2 are only for examples and do not limit the table.

[0035] Table 2

[0036]

[0037] In an embodiment of the present application, the execution trigger timing of S110 may be when the access control device goes online on the attendance management client. Going online may refer to the first registration and going online, or may refer to the re - online of the access control device that has been registered on the attendance management client after going offline. It can also be manually triggered to meet more software application scenarios.

[0038] S120. Compare the verification fields of the first personnel database verification information and the second personnel database verification information; wherein, the verification fields include: personnel identification and personnel information hash value.

[0039] Exemplarily, the first personnel database verification information and the second personnel database verification information may include one or several of personnel database identification, personnel identification, personnel text information, personnel text information hash value, and personnel image hash value, and do not necessarily include all of the above verification information. For example, as shown in Table 1 and Table 2, the first personnel database verification information includes the verification information corresponding to personnel ID4, but the second personnel database verification information does not include the verification information corresponding to personnel ID4. In an embodiment of the present application, the verification fields of the first personnel database verification information and the second personnel database verification information are compared to determine which verification fields do not exist, and which verification fields exist but are inconsistent, between the first personnel database verification information and the second personnel database verification information.

[0040] S130. Synchronize the first personnel database of the first terminal and the second personnel database in the second terminal according to the comparison result.

[0041] Specifically, the comparison method may be: check whether there is a personnel identification in the personnel identification of the second personnel database verification information that matches the personnel identification in the first personnel database verification information. If not, synchronize the personnel information corresponding to the personnel identification. If it exists, then determine whether the personnel information hash value in the first personnel database verification information corresponding to the same personnel identification is consistent with the personnel information hash value in the second personnel database verification information. In the case where the personnel information hash values are inconsistent, synchronize the personnel information corresponding to the personnel identification.

[0042] In an embodiment of the present application, obtain the first personnel database verification information of the first terminal and the second personnel database verification information of the second terminal; compare the verification fields of the first personnel database verification information and the second personnel database verification information, so as to efficiently and accurately determine whether the information in the first personnel database and the second personnel database is consistent according to the comparison of the verification fields of the first personnel database verification information and the second personnel database verification information. Synchronize the first personnel database of the first terminal and the second personnel database in the second terminal according to the comparison result, so as to realize the two - way synchronization of the personnel databases in the first terminal and the second terminal, and ensure the consistency of the data in the first terminal and the second terminal.

[0043] In an embodiment of the present application, synchronizing the first personnel database of the first terminal and the second personnel database in the second terminal according to the comparison result includes: if any personnel identifier appears in the verification information of the first personnel database and does not appear in the verification information of the second personnel database, then synchronize the personnel database corresponding to this personnel identifier from the first terminal to the second terminal; if any personnel identifier appears in the verification information of the second personnel database and does not appear in the verification information of the first personnel database, then synchronize the personnel database corresponding to this personnel identifier from the second terminal to the first terminal.

[0044] The above solution is a solution adopted when a personnel identifier exists in one terminal but not in the other during the personnel identifier comparison process. It is also applicable to the personnel database identifier comparison process.

[0045] In an embodiment of the present application, the verification field further includes personnel text information, and the personnel information hash value includes a personnel text information hash value; accordingly, synchronizing the first personnel database of the first terminal and the second personnel database in the second terminal according to the comparison result includes: if there is a match in the personnel identifier comparison between the verification information of the first personnel database and the verification information of the second personnel database, then compare the personnel text information hash values corresponding to this personnel identifier; if the personnel text information hash value in the verification information of the first personnel database corresponding to this personnel identifier is inconsistent with the personnel text information hash value in the verification information of the second personnel database, then compare the personnel text information corresponding to this personnel identifier; if the personnel text information in the verification information of the first personnel database corresponding to this personnel identifier is inconsistent with the personnel text information in the verification information of the second personnel database, then synchronize the personnel text information in the first terminal and the personnel text information in the second terminal.

[0046] And / or, the personnel information hash value includes a personnel image hash value; accordingly, synchronizing the first personnel database of the first terminal and the second personnel database in the second terminal according to the comparison result includes: if there is a match in the personnel identifier comparison between the verification information of the first personnel database and the verification information of the second personnel database, then compare the personnel image hash values corresponding to this personnel identifier; if the personnel image hash value in the verification information of the first personnel database corresponding to this personnel identifier is inconsistent with the personnel image hash value in the verification information of the second personnel database, then synchronize the personnel images in the first terminal and the personnel images in the second terminal.

[0047] Exemplarily, such as Figure 4As shown, first compare the personnel library identifier in the first personnel library verification information with the personnel library identifier in the second personnel library verification information. If the comparison is inconsistent, perform a synchronization operation to synchronize the personnel library corresponding to the existing personnel library identifier to another terminal, or use the personnel library information in the attendance client as the standard to synchronize the personnel library of the attendance management client to the access control device. If the comparison is consistent, then compare the personnel identifier in the first personnel library verification information with the personnel identifier in the second personnel library verification information. If the comparison is inconsistent, perform a synchronization operation. If the personnel identifier exists in the personnel library verification information of one terminal but does not exist in the personnel library verification information of the other terminal, then synchronize the personnel library corresponding to the existing personnel identifier to the other terminal. If the comparison is consistent, enter Process A, as Figure 5 shown, compare the hash value of the personnel text information in the first personnel library verification information corresponding to the personnel identifier with the hash value of the personnel text information in the second personnel library verification information. If they are consistent, no synchronization operation is performed. If they are inconsistent, then compare the personnel text information in the first personnel library verification information corresponding to the personnel identifier with the personnel text information in the second personnel library verification information. If they are consistent, no synchronization operation is performed. If they are inconsistent, perform a personnel text information synchronization operation.

[0048] Specifically, if the hash value of the personnel text information in the first personnel library verification information is inconsistent with the hash value of the personnel text information in the second personnel library verification information, then further compare the personnel text information. If a certain verification field in the personnel text information exists in the first personnel library verification information but does not exist in the second personnel library verification information, then copy the personnel library information corresponding to this field from the first terminal to the second terminal. If a certain verification field in the personnel text information exists in the second personnel library verification information but does not exist in the first personnel library verification information, then copy the personnel library information corresponding to this field from the second terminal to the first terminal. If a certain verification field in the personnel text information exists in both the first personnel library verification information and the second personnel library verification information but is inconsistent, then synchronize it to be consistent according to the actual situation.

[0049] In the embodiment of the present application, for the situation where a certain verification field in the personnel text information exists in both the first personnel library verification information and the second personnel library verification information but is inconsistent, the following refinement solution is proposed: If the first terminal is the attendance management client and the second terminal is the access control device, then if the personnel text information in the first personnel library verification information corresponding to the personnel identifier is inconsistent with the personnel text information in the second personnel library verification information, synchronize the personnel text information in the first terminal and the personnel text information in the second terminal, including: synchronizing the personnel text information corresponding to the personnel identifier in the attendance management client to the access control device.

[0050] If a certain verification field exists in both the first personnel database verification information and the second personnel database verification information but is inconsistent, the personnel database information in the attendance management client is synchronized to the access control device, that is, synchronization is performed based on the personnel database information in the attendance management client. The unit's personnel management staff manually manages the information of all personnel through the attendance management client, and only the unit's personnel management staff has the operation authority. Therefore, the information in the attendance management client has a high credibility. When synchronization is required due to inconsistent verification fields, the information in the attendance management client is used as the standard, which improves the accuracy and reliability of the personnel database information.

[0051] If the personnel database identifiers in the first personnel database verification information and the second personnel database verification information are compared and found to be consistent, the comparison of the personnel image hash value can be performed simultaneously with the comparison of the personnel text information hash value, or the comparison of the personnel image hash value can be performed after the comparison of the personnel text information hash value. It is also possible to first perform the comparison of the personnel image hash value and then perform the comparison of the personnel text information hash value when the personnel database identifiers in the first personnel database verification information and the second personnel database verification information are compared and found to be consistent. If the personnel database identifiers in the first personnel database verification information and the second personnel database verification information are compared and found to be consistent, the personnel image hash values in the first personnel database verification information and the second personnel database verification information corresponding to the personnel identifier are compared. If the comparison is consistent, no synchronization operation is performed. If the comparison is inconsistent, a personnel image synchronization operation is performed. Figure 4 and Figure 5 Both parties in [reference] refer to the first terminal and the second terminal. The other party refers to the terminal that needs to be synchronized and updated.

[0052] In the embodiment of the present application, when comparing subsequent verification fields in the case where the personnel database identifiers are compared and found to be consistent, the verification field comparison between the first personnel database verification information and the second personnel database verification information includes: determining the addressing addresses in the first personnel database verification information and the second personnel database verification information according to the personnel identifier of the target personnel; according to the addressing addresses, searching for the first verification information of the target personnel from the first personnel database verification information and searching for the second verification information of the target personnel from the second personnel database verification information; and performing a verification field comparison on the first verification information and the second verification information.

[0053] Exemplarily, as shown in Table 1 and Table 2, for the target personnel to be compared, the corresponding addressing addresses are determined according to the personnel identifier of the target personnel, and the addressing addresses can be set to be the same as the personnel identifier. Through the addressing addresses, the position of the verification information of the target personnel in the verification information table can be quickly locked, so as to quickly and efficiently find the verification information for comparison and improve the comparison efficiency.

[0054] Figure 6 The flowchart of the information synchronization method provided by another embodiment of the present invention. The embodiments of the present application are further optimizations of the above embodiments. For details not described in detail in the embodiments of the present application, please refer to the above embodiments. Refer to Figure 6 , the information synchronization method provided by the embodiments of the present application may include:

[0055] S210. Obtain the first personnel database verification information of the first terminal and the second personnel database verification information of the second terminal.

[0056] S220. Compare the verification fields included in the first verification information and the verification fields included in the second verification information according to the priority order of the verification fields; wherein, the priority order of the verification fields is: personnel identifier, hash value of personnel text information.

[0057] In the embodiments of the present application, progressive comparison of the verification fields is performed, that is, comparison is performed according to the priority order of the verification fields, so as to perform hierarchical comparison to improve the comparison speed and efficiency. For example, if the personnel identifier and the hash value of the personnel information are both compared and consistent, it means that the first personnel database in the first terminal is consistent with the second personnel database in the second terminal, so other operations may not be performed. If the personnel identifiers are not compared consistently, the personnel databases are synchronized. If the personnel identifiers are compared consistently, the hash value of the personnel information corresponding to the personnel identifier is further compared.

[0058] S230. During the comparison according to the priority order, if the verification fields corresponding to the current priority are not compared consistently, synchronize the first personnel database of the first terminal and the second personnel database in the second terminal.

[0059] Exemplarily, check whether there is a personnel identifier in the personnel identifier of the second personnel database verification information that matches the personnel identifier in the first personnel database verification information. If not, synchronize the personnel database corresponding to the existing personnel identifier to the terminal where the personnel identifier does not exist. If it exists, then determine whether they are consistent. If not, synchronize the personnel information corresponding to the personnel identifier. If they are consistent, determine whether the hash value of the personnel information in the first personnel database verification information corresponding to the same personnel identifier is consistent with the hash value of the personnel information in the second personnel database verification information. If not, synchronize the personnel information corresponding to the personnel identifier.

[0060] In the embodiments of the present application, if the comparison of the personnel identifier or the hash value of the personnel information is inconsistent, personnel database synchronization is required. The solution adopted according to the specific information of the personnel database to be synchronized is as follows: If it is necessary to synchronize the personnel text information corresponding to the personnel identifier in the personnel database information, directly use the personnel text information in the personnel database verification information obtained by the Agent to update the personnel database information of another terminal. If it is necessary to synchronize the personnel image corresponding to the personnel identifier in the personnel database information, send a personnel image acquisition request to the terminal containing the accurate personnel image, and receive the personnel image carried with the synchronization direction flag bit returned by the terminal. Then, determine the receiving terminal among the first terminal and the second terminal according to the synchronization direction flag bit, and send it to update the personnel image of the receiving terminal.

[0061] S240. Receive the personnel database change request carried with the synchronization direction flag bit sent by the first terminal or the second terminal.

[0062] Exemplarily, after the two-way synchronization of the personnel database is completed, if there is an update in the personnel database of either the first terminal or the second terminal, send a personnel database change request carried with the synchronization direction flag bit to the Agent. The Agent determines which terminal's data needs to be synchronized to which terminal according to the synchronization direction flag bit. The change request may include the synchronization direction flag bit, the personnel database identifier, the personnel identifier, and the change content, etc.

[0063] S250. According to the synchronization direction flag bit, determine the active change terminal and the passive change terminal among the first terminal and the second terminal.

[0064] For example, it can be set that when the synchronization direction flag bit is 0, it means that the first terminal is the active change terminal and the second terminal is the passive change terminal, and the data in the first terminal needs to be updated to the second terminal. When the synchronization direction flag bit is 1, it means that the first terminal is the passive change terminal and the second terminal is the active change terminal, and the data in the second terminal needs to be updated to the first terminal. It can also be set vice versa according to the actual situation.

[0065] S260. Synchronize the personnel database in the passive change terminal according to the personnel database in the active change terminal.

[0066] Exemplarily, synchronize and copy the updated personnel database information in the active change terminal to the personnel database information in the passive update terminal, so as to realize the information synchronization between the first terminal and the second terminal.

[0067] The technical solution in the embodiments of the present application performs progressive comparison according to the priority order of the check fields and performs search comparison according to the addressing address, thereby effectively improving the efficiency of the check information comparison and improving the real-time performance of the terminal information synchronization.

[0068] Figure 7 The flowchart of the information synchronization method provided by another embodiment of the present invention. The embodiments of the present application optimize the above embodiments, and for the details not described in detail in the embodiments of the present application, please refer to the above embodiments. Refer to Figure 7 , the information synchronization method provided by the embodiments of the present application may include:

[0069] S310. Obtain the first personnel library verification information of the first terminal and the second personnel library verification information of the second terminal.

[0070] S320. Compare the verification fields of the first personnel library verification information and the second personnel library verification information; wherein, the verification fields include: personnel identifier and personnel information hash value.

[0071] S330. Synchronize the first personnel library of the first terminal and the second personnel library in the second terminal according to the comparison result.

[0072] S340. Receive the updated personnel library verification information returned by the terminal with a personnel library update among the first terminal and the second terminal.

[0073] Exemplarily, when the personnel text information or personnel image of the first terminal or the second terminal is updated, the corresponding personnel text information hash value or personnel image hash value will be updated. To ensure the consistency of the personnel library information on both sides, after the synchronization of the personnel text information or personnel image corresponding to the same personnel identifier is completed, a synchronization success signal and the updated local personnel text information hash value and / or personnel image hash value are returned to the Agent.

[0074] S350. Compare the updated personnel library verification information with the personnel library verification information corresponding to the other terminal; wherein, the other terminal is the terminal other than the terminal corresponding to the updated personnel library verification information among the first terminal and the second terminal.

[0075] S360. If the comparison is consistent, it is determined that the personnel library synchronization is successful.

[0076] Exemplarily, the Agent compares the received personnel text information hash value and / or personnel image hash value with the personnel text information hash value and / or personnel image hash value corresponding to the same personnel identifier in the personnel library of the other terminal. If they are consistent, it is determined that the synchronization is successful; otherwise, it is determined that the synchronization fails. If the synchronization is successful, the Agent triggers the update of the verification information in the corresponding personnel library information verification table to ensure the consistency of the bilateral personnel library information verification tables.

[0077] S370. If the updated personnel library verification information returned by the terminal with a personnel library update among the first terminal and the second terminal is not received within the preset time, or the comparison is inconsistent, perform a retry synchronization.

[0078] If the updated personnel database verification information is not received within the preset time, or the comparison of the updated personnel database verification information is inconsistent, it may be a synchronization failure. The Agent triggers the resynchronization of the corresponding information. If the preset number of retries, such as 3 times, still fails to synchronize successfully, an information indicating the failure of synchronizing the personnel image or personnel text information is generated.

[0079] In the solution of the embodiment of the present application, the verification information returned by the terminal with data changes is compared to further verify whether the synchronization is successful, effectively ensuring the consistency of the terminal data. And if the updated personnel database verification information returned by the terminal with a personnel database update in the first terminal and the second terminal is not received within the preset time, or the comparison is inconsistent, then the resynchronization is performed, thereby improving the ability to handle program exceptions.
