Embodiment 1

[0033] figure 1 It is a schematic structural diagram of a time synchronization device provided by an embodiment of the present invention. like figure 1 As shown, the time synchronization device includes: a target server 2 and a client 3 (also referred to as a terminal or an application server) connected through a target network 1 . like figure 2 As shown, the first time synchronization software module 10 based on the domestic Linux system (or called the domestic Linux operating system) is installed on the target server 2, and the first time synchronization software module 10 includes a timing card 11 and a first kernel driver 12, The second time synchronization software module 20 based on the domestic Linux system is installed on the client 3, and the second time synchronization software module 20 includes the second kernel driver 21;

[0034] The timing card 11 is used to obtain the time reference signal from the target B code terminal, and sends the time reference signal...

Embodiment 2

[0063] According to an embodiment of the present invention, an embodiment of a time synchronization method is provided. It should be noted that the steps shown in the flowcharts of the drawings can be executed in a computer system such as a set of computer-executable instructions, and, although A logical order is shown in the flowcharts, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0064] Figure 6 A flowchart of a time synchronization method provided by an embodiment of the present invention, the method is applied to the first time synchronization software module of the time synchronization device in Embodiment 1, such as Figure 6 As shown, the method includes the following steps:

[0065] Step S101, receiving the time reference signal obtained by the time system card from the target B code terminal;

[0066] Step S102, correct the time of the target server based on the time reference signal, a...

Abstract

The invention provides a time synchronization device and method, and relates to the technical field of communication, and the device comprises a target server and a client. A first time synchronization software module based on a domestic Linux system is installed on the target server, the first time synchronization software module comprises a timing unification card and a first kernel driver, a second time synchronization software module based on the domestic Linux system is installed on the client, and the second time synchronization software module comprises a second kernel driver; the timing unification card is used for acquiring a time reference signal from a target B code terminal and sending the time reference signal to the first kernel driver; the first kernel driver is used for carrying out time calibration on the target server based on the time reference signal; and the second kernel driver is used for carrying out network timing on the client based on the time information after timing. According to the time synchronization device set based on the domestic Linux system, the time of the target server and the time of the client can be kept synchronous, and the information security is ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a time synchronization device and method. Background technique [0002] The time synchronization method in the prior art can only rely on imported equipment to work, so the problem of information security cannot be guaranteed. In addition, after investigation, there is no localized related product found in the market to provide time synchronization function. Contents of the invention [0003] The purpose of the present invention is to provide a time synchronization device and method to alleviate the technical problem in the prior art that the time synchronization function is limited by imported equipment and cannot guarantee information security. [0004] In the first aspect, a time synchronization device provided by the present invention includes: a target server and a client connected through a target network; wherein, a first time synchronization software m...
