Description

Technical Field

[0001] The present invention relates to the field of computer internet technology, and in particular to a centralized and convenient network timing method. Background Art

[0002] With the rapid development of computer technology and the Internet, computers play a vital role in data processing and transmission. However, the accuracy of computer clocks is relatively low, and there may be time offsets of several seconds or even minutes within a day. This time accuracy is difficult to meet the requirements of business areas with higher time accuracy. Therefore, how to conveniently and quickly achieve high-accuracy network time synchronization in numerous network systems is a very important issue.

[0003] The general procedure involves finding a suitable time source and then selecting different time synchronization methods based on the device's operating system. For Windows systems, the built-in w32time tool is generally used. w32time is easy to use and can achieve second-level time synchronization accuracy, but it cannot meet the needs of applications requiring higher time precision. For open-source Linux systems and domestically produced systems, there are generally two time synchronization tools: ntpd and chrony. Both tools can achieve millisecond-level time accuracy, but they can only be configured and used using the command line, requiring personnel with certain network knowledge to complete deployment and use, and cannot be deployed quickly and on a large scale. Using open-source software also comes with various open-source vulnerabilities, requiring maintenance personnel to manually upgrade each device in a timely manner. After deployment, the appropriate time source address may change during use, resulting in the need to reconfigure many devices that require time synchronization.

If the LAN timing module receives the "Search Timing Module" data packet and the timing module is in normal status, the timing module sends the "Available Timing Module Address: IP" data packet to the time synchronization module. The time synchronization module receives the "Available Timing Module Address: IP" data packet sent by the timing module and sends the timing module address to the user. After the user selects the timing module and submits it, the time synchronization module uses the timing module as the superior time source for time synchronization.

10. A centralized and portable network timing method according to claim 1, characterized in that: The step S8 specifically includes the following contents: S801: The time synchronization module receives an upgrade request or a request to execute an upgrade at a scheduled time; S802, the time synchronization module sends a "query time synchronization module upgrade package" data packet to the timing module; S803, the timing module receives the "query time synchronization module upgrade package" data packet, and the timing module sends the "latest upgrade package version number" data packet to the time synchronization module; S804: The time synchronization module determines whether the "latest upgrade package version number" is greater than the current version number of the time synchronization module. If so, step S805 is executed. If not, a prompt is sent to the user indicating that the latest version is currently available, and the execution ends. S805, the time synchronization module sends a "download the latest upgrade package version" data packet to the timing module; S806: The timing module receives the "download latest upgrade package version" data packet from the time synchronization module, and the timing module sends the "latest upgrade package" data packet to the time synchronization module; S807, the time synchronization module receives the "latest upgrade package" data packet sent by the timing module, and the time synchronization module automatically completes the upgrade according to the "latest upgrade package" data packet and prompts the user that the upgrade is complete; S808: Complete a time synchronization module upgrade.
