[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0053] In a first aspect, an embodiment of the present invention provides a clock synchronization device.

[0054] Reference Figure 1 , Figure 1 The hardware structure diagram of the clock synchronization device involved in the embodiment of the present invention. In the embodiment of the present invention, the clock synchronization device may include a processor 1001 (e.g., a central processing unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface, a wireless interface (such as wireless fidelity WIreless-FIdelity, WI-FI interface); the memory 1005 may be a high-speed random access memory (random access memory, RAM), or a stable memory (non-volatile memory), such as a disk storage, and the memory 1005 may optionally be a storage device independent of the aforementioned processor 1001. Those skilled in the art will understand that Figure 1 The hardware structure shown in the figure does not constitute a limitation of the present invention, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0055] Continue to refer to Figure 1 , Figure 1 The memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module and a clock synchronization program. The processor 1001 may call the clock synchronization program stored in the memory 1005 and execute the clock synchronization method provided in the embodiment of the present invention.

[0056] In a second aspect, an embodiment of the present invention provides a clock synchronization method.

[0057] In one embodiment, referring to Figure 2 , Figure 2 FIG. 1 is a flow chart of an embodiment of a clock synchronization method of the present invention. Figure 2 As shown, the clock synchronization method includes:

[0058] Step S10, starting the operating system, reading the 1588 network card driver and the compensation value file corresponding to the operating system, wherein the compensation value file records clock synchronization compensation values ​​corresponding to different system loads;

[0059] In this embodiment, the execution subject (e.g., server) of the clock synchronization method starts the operating system, which can be selected by the user based on actual needs. After the operating system is started, the 1588 network card driver and the compensation value file corresponding to the operating system are automatically read from the memory, wherein the compensation value file records the clock synchronization compensation values ​​corresponding to different system loads.

[0060] Further, in one embodiment, referring to Figure 3 , Figure 3 FIG. 2 is a flow chart of another embodiment of the clock synchronization method of the present invention. Figure 3 As shown, before step S10, it also includes:

[0061] After the operating system starts, read the 1588 network card driver source code;

[0062] Compile the 1588 network card driver source code to obtain the 1588 network card driver, and replace the network card driver of the operating system with the 1588 network card driver;

[0063] Selecting a system load that has not been selected from the load record table, where the load record table records multiple system loads;

[0064] Set the system load of the operating system to the selected system load;

[0065] Selecting a clock synchronization compensation value that has not been selected from the compensation value record table, wherein the compensation value record table records a plurality of clock synchronization compensation values;

[0066] Detecting whether a synchronization accuracy error of clock synchronization performed with the selected clock synchronization compensation value is less than or equal to a preset threshold;

[0067] If it is less than or equal to the preset threshold, the selected system load, the selected clock synchronization compensation value and the operating system model are stored as a set of associated data, and the step of selecting a clock synchronization compensation value that has not been selected from the compensation value record table is returned;

[0068] If it is greater than the preset threshold, returning to the step of selecting a clock synchronization compensation value that has not been selected from the compensation value record table;

[0069] When the multiple clock synchronization compensation values ​​recorded in the compensation value record table have all been selected, the multiple clock synchronization compensation values ​​recorded in the compensation value record table are set to an unselected state, and the process returns to the step of selecting a system load that has not been selected from the load record table;

[0070] When the multiple system loads recorded in the load record table are all selected, the 1588 network card driver is stored, and a compensation value file corresponding to the operating system is generated and stored based on all the stored group association data.

[0071] In this embodiment, the operating system is started, and the operating system can be selected by the user based on actual needs. After the operating system is started, the 1588 network card driver source code is automatically read from the memory, the 1588 network card driver source code is compiled to obtain the 1588 network card driver, and the network card driver of the operating system is replaced by the 1588 network card driver.

[0072] A system load that has not been selected is selected from the load record table. The load record table records multiple system loads. For example, the load record table records 100 system loads, which are system loads 1 to 100 respectively. The system load consists of a CPU load and a network card load.

[0073] For example, first select system load 1 and set the system load of the operating system to system load 1.

[0074] Then, a clock synchronization compensation value that has not been selected is selected from the compensation value record table, where a plurality of clock synchronization compensation values ​​are recorded. For example, the compensation value record table records 200 clock synchronization compensation values.

[0075] For example, a clock synchronization compensation value of 1 is selected, and it is detected whether the synchronization accuracy error of clock synchronization performed with the selected clock synchronization compensation value is less than or equal to a preset threshold. Specifically, by executing the ptp4l program and combining the clock synchronization compensation value of 1 for clock synchronization, the log file of the ptp4l program is analyzed to determine whether the synchronization accuracy error of clock synchronization performed with the clock synchronization compensation value of 1 is less than or equal to the preset threshold.

[0076] If it is less than or equal to the preset threshold, the selected system load, the selected clock synchronization compensation value and the operating system model are stored as a set of related data, and when there is a clock synchronization compensation value that has not been selected in the compensation value record table, return to the step of selecting a clock synchronization compensation value that has not been selected from the compensation value record table.

[0077] If it is greater than the preset threshold, when there is a clock synchronization compensation value that has not been selected in the compensation value record table, the process returns to the step of selecting a clock synchronization compensation value that has not been selected from the compensation value record table.

[0078] When multiple clock synchronization compensation values ​​recorded in the compensation value record table have all been selected, the multiple clock synchronization compensation values ​​recorded in the compensation value record table are set to an unselected state, and when there is a system load that has not been selected in the load record table, return to the step of selecting a system load that has not been selected from the load record table.

[0079] When the multiple system loads recorded in the load record table are all selected, the 1588 network card driver is stored, and a compensation value file corresponding to the operating system is generated and stored based on all the stored group association data.

[0080] For example, the total group association data stored includes:

[0081] System load 1--clock synchronization compensation value 1--operating system model OS1, system load 1--clock synchronization compensation value 2--operating system model OS1, system load 1--clock synchronization compensation value 3--operating system model OS1, ..., system load 100--clock synchronization compensation value 199--operating system model OS1. The compensation value file corresponding to the operating system model OS1 generated based on all the stored group association data records the clock synchronization compensation values ​​corresponding to different system loads.

[0082] Repeat the above steps to obtain compensation value files corresponding to multiple operating systems.

[0083] The 1588 network card driver and the compensation value file corresponding to the operating system are stored in a field replaceable unit (eg, a solid state hard disk) of the server.

[0084] Through the above steps, when executing step S10, the 1588 network card driver and the compensation value file corresponding to the operating system can be directly read from the field replaceable unit of the server. The step of recompiling the driver is omitted. And by automatically simulating different system loads and determining the appropriate clock synchronization compensation value corresponding to each system load, the service scenario coverage is improved, thereby ensuring the stability of subsequent system services.

[0085] Step S20, replacing the network card driver of the operating system with the 1588 network card driver;

[0086] In this embodiment, the network card driver of the operating system is replaced by the read 1588 network card driver.

[0087] Step S30, obtaining the actual system load, and determining the actual clock synchronization compensation value corresponding to the actual system load according to the compensation value file, and performing clock synchronization with the actual clock synchronization compensation value.

[0088] In this embodiment, the actual system load is obtained. Since the compensation value file records the clock synchronization compensation values ​​corresponding to different system loads, the actual clock synchronization compensation value corresponding to the actual system load can be determined based on the compensation value file, so that clock synchronization is performed with the actual clock synchronization compensation value.

[0089] Further, in one embodiment, referring to Figure 4 , Figure 4 The figure is a detailed flow chart of determining the actual clock synchronization compensation value corresponding to the actual system load according to the compensation value file. Figure 4 As shown, the step of determining the actual clock synchronization compensation value corresponding to the actual system load according to the compensation value file includes:

[0090] Determine from the compensation value file a target system load that matches the actual system load, and multiple clock synchronization compensation values ​​corresponding to the target system load; select a clock synchronization compensation value that has not been selected from the multiple clock synchronization compensation values ​​corresponding to the target system load; detect whether the synchronization accuracy error of clock synchronization performed with the selected clock synchronization compensation value is less than or equal to a preset threshold; if it is less than or equal to the preset threshold, use the selected clock synchronization compensation value as the actual clock synchronization compensation value; if it is greater than the preset threshold, return to the step of selecting a clock synchronization compensation value that has not been selected from the multiple clock synchronization compensation values ​​corresponding to the target system load.

[0091] In this embodiment, the compensation value file determines the system load closest to the actual system load as the target system load matching the actual system load, and multiple clock synchronization compensation values ​​corresponding to the target system load.

[0092] A clock synchronization compensation value that has not been selected is selected from multiple clock synchronization compensation values ​​corresponding to the target system load, and it is detected whether the synchronization accuracy error of clock synchronization performed with the selected clock synchronization compensation value is less than or equal to a preset threshold. For example, by executing the ptp4l program and combining the selected clock synchronization compensation value to perform clock synchronization, the log file of the ptp4l program is analyzed to determine whether the synchronization accuracy error of clock synchronization performed with the selected clock synchronization compensation value is less than or equal to the preset threshold.

[0093] If it is less than or equal to the preset threshold, the selected clock synchronization compensation value is used as the actual clock synchronization compensation value; if it is greater than the preset threshold, return to the step of selecting a clock synchronization compensation value that has not been selected from multiple clock synchronization compensation values ​​corresponding to the target system load.

[0094] Further, in one embodiment, the step of detecting whether the synchronization accuracy error of clock synchronization performed with the selected clock synchronization compensation value is less than or equal to a preset threshold comprises:

[0095] Run the clock synchronization program and perform clock synchronization with the selected clock synchronization compensation value; obtain the log file output by the clock synchronization program; analyze the log file to obtain the synchronization accuracy error of the clock synchronization with the selected clock synchronization compensation value; detect whether the synchronization accuracy error is less than or equal to a preset threshold.

[0096] In this embodiment, a clock synchronization program is run, and clock synchronization is performed with the selected clock synchronization compensation value, wherein the clock synchronization program may use the ptp4l program. A log file output by the clock synchronization program is obtained, and the log file is analyzed to obtain a synchronization accuracy error of clock synchronization with the selected clock synchronization compensation value, and finally, whether the synchronization accuracy error is less than or equal to a preset threshold is detected.

[0097] In this embodiment, the 1588 protocol stack and services are implemented through a general program, which can be decoupled from the hardware and improve the versatility.

[0098] Furthermore, in one embodiment, after step S20, the method further includes:

[0099] Perform clock synchronization with the default clock synchronization offset value;

[0100] It is detected whether the synchronization accuracy error of clock synchronization performed with a default clock synchronization compensation value is less than or equal to a preset threshold.

[0101] In this embodiment, the default clock synchronization compensation value is set according to actual needs, for example, it is set to 0, and the clock synchronization is performed by running the clock synchronization program ptp41 and using the default clock synchronization compensation value. The log file output by the clock synchronization program is obtained, and the log file is analyzed to obtain the synchronization accuracy error of the clock synchronization performed with the selected clock synchronization compensation value, and the synchronization accuracy error is compared with the preset threshold.

[0102] If it is greater than the preset threshold, step S30 is executed.

[0103] That is, in this embodiment, step S30 is executed only if the synchronization accuracy error of clock synchronization performed using the default clock synchronization compensation value is greater than the preset threshold.

[0104] In this embodiment, the operating system is started, the 1588 network card driver and the compensation value file corresponding to the operating system are read, and the compensation value file records the clock synchronization compensation values ​​corresponding to different system loads; the network card driver of the operating system is replaced with the 1588 network card driver; the actual system load is obtained, and the actual clock synchronization compensation value corresponding to the actual system load is determined according to the compensation value file, and the clock synchronization is performed with the actual clock synchronization compensation value. Through this embodiment, the corresponding clock synchronization compensation value can be selected according to the actual system load for clock synchronization, thereby improving the accuracy of clock synchronization.

[0105] Furthermore, in one embodiment, after step S30, the method further includes:

[0106] When the system load change rate is greater than the preset change rate, a new clock synchronization compensation value corresponding to the new system load is determined according to the compensation value file, and clock synchronization is performed with the new clock synchronization compensation value.

[0107] In this embodiment, the system load can be obtained at a preset time interval. When the system load change rate calculated by the system load at a certain moment (i.e., the new system load) and the system load at the previous moment is greater than the preset change rate, a new clock synchronization compensation value corresponding to the new system load is determined according to the compensation value file, and clock synchronization is performed with the new clock synchronization compensation value. The specific implementation of determining the new clock synchronization compensation value corresponding to the new system load according to the compensation value file can refer to the above-mentioned embodiment of determining the actual clock synchronization compensation value corresponding to the actual system load according to the compensation value file, which will not be described in detail here.
