Detailed Description
The embodiment of the invention provides a biological template data synchronization method, a biological template data synchronization device, biological template data synchronization equipment and a biological template data synchronization storage medium, which are used for solving the technical problems that in the prior art, a database needs to store a large number of commands, a server needs to respond to a large number of concurrent requests, and huge pressure is caused on the server and the database.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a biometric template data synchronization method according to an embodiment of the present invention, the method is applied to a server, and the server is in communication with a device.
The invention provides a biological template data synchronization method, which comprises the following steps:
in the embodiment of the invention, when the server generates the first command data, the commands are not stored into the database one by one, but are stored into the preset file according to the PUSH protocol.
It should be noted that the default file may be uncompressed or compressed into a format such as zip or tgz according to convention. Taking the tgz format as an example, the designation may be "123456789, tgz". Each line of commands may end with r \ n \ r \ n. In one example, the naming format may be as follows:
C:1:DATA UPDATE user CardNo＝Pin＝666888 Password＝Group＝1
StartTime＝0 EndTime＝0 Name＝michael Privilege＝0
C:2:DATA UPDATE userauthorize Pin＝666888 AuthorizeTimezoneId＝1
AuthorizeDoorId＝1
C:3:DATA UPDATE BIOPHOTO PIN＝666888 Type＝9 Format＝1
Url＝iclock/file/biophoto/default_666888.jpg
103, generating second command data of the preset file;
in the embodiment of the present invention, after all the first command data are stored in the preset file, a second command data may be generated and stored in the preset database for the device to obtain when requesting, so as to download the file.
In one example, the second command data may be selected in the format shown below:
DATA UPDATE FILE_COMMAND ContentType＝tgz url＝iclock/file/download/123456789.tgz
wherein, FILE _ COMMAND represents the address type of txt, zip, tgz, url, etc. supported by the ContentType for the device to download FILEs in a FILE manner.
It should be noted that, according to different sources of the stored biometric templates, a plurality of preset files may be set to store corresponding first command data, and generate corresponding second command data for each preset file and store the second command data in the database.
in the embodiment of the present invention, after the device sends the command obtaining request and receives the second command data, the server may send the second command data to the device, so that the device may obtain the preset file via the second command data.
In the embodiment of the present invention, after acquiring the second command data, the device may analyze the second command data, so as to download the corresponding preset file from the server according to the command protocol. After the device downloads the preset file, the device analyzes the preset file, and can acquire a plurality of pieces of first command data so as to acquire corresponding biological template data according to the first command data.
In one example, the number of the devices may be multiple, and may be specifically selected according to actual situations. Taking 100 devices as an example, to synchronize the biometric template data to the 100 devices, each device only needs to store one command in the database of the server, that is, only 100 commands need to be stored in the database, and the device only needs to send 100 requests to the server, so that the synchronization of the biometric template data can be completed. This is equivalent to task balancing, and the tasks are all distributed to the devices to be completed, so that the time consumed by pulling data is reduced. It should be noted that the biometric template data synchronization of 100 devices may be performed concurrently.
In this embodiment of the present invention, after the synchronizing the preset file to the device when receiving a download request issued by the device for analyzing the second command data, the method further includes:
and receiving a synchronization result returned by the equipment.
In the embodiment of the invention, the device downloads the preset file, and after analysis and processing, the result can be returned to the server, so that the server can know the synchronization condition of the device in real time.
In one example, the downloaded file can be continuously transmitted at a selected breakpoint, so that the processing pressure of the background of the server is reduced, the concurrency capability is improved, the server configuration requirements of a client can be reduced, and the cost is reduced.
According to the invention, the first command data related to the biological template data are stored in the preset file, the second command data of the preset file are generated, and the second command data are stored in the preset database. In addition, when the device initiates a request to the server, all the first command data in the whole preset file can be downloaded from the server according to the second command data only by requesting the second command data, namely, the server only needs to respond to the request aiming at the second command data, so that the number of requests to be responded by the server is greatly reduced, and the time required for synchronizing the biological template data is saved.
