Detailed Description
For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a schematic flow chart of a first method for implementing timing of a multi NTP server according to an embodiment of the present invention, and as shown in fig. 1, the method for implementing timing of a multi NTP server includes steps S110 to S140, which specifically include the following steps:
step S110, establishing an NTP server list; the NTP server list comprises a plurality of NTP server addresses, each NTP server address corresponds to one NTP server, and each NTP server address comprises a domain name address and an IP address.
When the DNS service of a service operator has a problem, the NTP server with the IP address can still normally access; when the IP address of the NTP server is changed, the NTP server with the domain name address can still normally access, and the condition that the NTP server cannot access through the domain name address or the DNS service of a service operator has problems is avoided, so that the utilization efficiency of the NTP server is effectively improved, and the fault tolerance of the system is effectively improved.
Step S120, selecting an NTP server address from the NTP server list, and acquiring NTP server time corresponding to the NTP server address; the multi-NTP server time correction implementation system comprises a time synchronization component module (Ntpdate), wherein the time synchronization component module accesses an NTP server by using an NTP server address and acquires NTP server time so as to conveniently synchronize the NTP server time to each broadcasting terminal, thereby realizing the time synchronization of each broadcasting terminal and further ensuring the consistency of broadcasting sound of each broadcasting terminal.
Step S130, judging whether the time acquisition of the NTP server is successful, if not, switching to step S120 to select another NTP server address from the NTP server list again to acquire the time of another NTP server; if yes, go to step S140; in this embodiment, the terminal may be a broadcast terminal.
If the time synchronization component module cannot access the NTP server through the NTP server address (for example, the NTP server cannot be accessed through the IP address, and meanwhile, the NTP server cannot be accessed through the domain name address due to a problem in the DNS service of a service operator), the time synchronization component module cannot normally acquire the time of the NTP server, and further cannot synchronize the time of the NTP server to each broadcast terminal, so that the time of each broadcast terminal cannot be synchronized; at this time, the time synchronization component module is required to select another NTP server address from the NTP server list again to acquire another NTP server time, so that the reliability is high, and the time correction effect of the broadcast terminal cannot be influenced because some NTP servers cannot access the time.
Step S140, comparing the current NTP server time with the local time, judging whether the absolute value of the difference value between the current NTP server time and the local time is higher than a preset value, and if not, replacing the local time with the current NTP server time; if yes, the procedure goes to step S120 to select another NTP server address from the NTP server list again to obtain another NTP server time; the preset value can be set to be one of values in 5-10 min, or set to be other values according to actual needs, specifically, the preset value is set according to the position of the broadcast terminal, and the current NTP server time is the real-time NTP server time successfully acquired by the time synchronization component module.
Specifically, the current NTP server time is compared with the local time, and if the difference value between the current NTP server time and the local time is not large, the current NTP server time acquired by the time synchronization component module through the NTP server address is considered to be correct, the current NTP server time acquired by the time synchronization component module is set to the terminal, and the local time of the terminal is replaced by the current NTP server time; if the difference value between the time synchronization component module and the NTP server is larger, the time synchronization component module is required to select another NTP server address from the NTP server list again to acquire the time of another NTP server, the fault tolerance is strong, and even if the time of the NTP server is wrong, the time of the broadcast terminal cannot be influenced.
Fig. 2 is a schematic flow chart of a second method for implementing timing of a multi NTP server according to an embodiment of the present invention, and as shown in fig. 2, the method for implementing timing of a multi NTP server includes steps S210 to S250, which are specifically as follows:
step S210, establishing an NTP server list; the NTP server list comprises a plurality of NTP server addresses, each NTP server address corresponds to one NTP server, and each NTP server address comprises a domain name address and an IP address.
When the DNS service of a service operator has a problem, the NTP server with the IP address can still normally access; when the IP address of the NTP server is changed, the NTP server with the domain name address can still normally access, and the condition that the NTP server cannot access through the domain name address or the DNS service of a service operator has problems is avoided, so that the utilization efficiency of the NTP server is effectively improved, and the fault tolerance of the system is effectively improved.
Step S220, selecting an NTP server address from the NTP server list, and acquiring an NTP server time corresponding to the NTP server address.
Step S230, judging whether the time acquisition of the NTP server is successful, if not, switching to step S220; if yes, the process proceeds to step S240.
If the time synchronization component module cannot access the NTP server through the NTP server address, the time synchronization component module cannot normally acquire the time of the NTP server, and further cannot synchronize the time of the NTP server to each broadcast terminal, so that the time of each broadcast terminal cannot be synchronized; at the moment, the time synchronization component module is required to select another NTP server address from the NTP server list again to acquire the time of another NTP server, the reliability is high, and the time correction effect of the broadcast terminal cannot be influenced because some NTP servers cannot access the time;
step S240, setting kcount to be 0, comparing the current NTP server time with the local time, judging whether the absolute value of the difference value between the current NTP server time and the local time is higher than a preset value, if not, replacing the local time with the current NTP server time, namely, setting the current NTP server time to the broadcast terminal; if yes, the process proceeds to step S250.
Step S250, let kcount be kcount +1, determine whether kcount is lower than a preset number N, if yes, go to step S220; if not, replacing the local time with the current NTP server time; wherein N is not less than 2, and N is 3.
Specifically, when the absolute value of the difference between the current NTP server time and the local time is higher than a preset value, adding 1 to the kcount count, that is, kcount ═ kcount + 1; when the absolute value of the difference value between the current NTP server time and the local time is continuously 3 times and is higher than the preset value, namely, kcount is 3, the current NTP server time acquired by the time synchronization component module can be judged to be correct, the local time is incorrect, then the current NTP server time is set for each broadcast terminal, so that the local time of each broadcast terminal is replaced, the consistency of broadcast sound of each broadcast terminal is further ensured, meanwhile, the fault tolerance is strong, and the broadcast terminal time cannot be influenced even if the NTP server time is wrong.
Other technical features of the second multi-NTP server timing implementation method are the same as those of the first multi-NTP server timing implementation method, and need not be described herein again.
Fig. 3 is a block diagram of a first multi-NTP server timing implementation system according to an embodiment of the present invention, and as shown in fig. 3, the system corresponds to the multi-NTP server timing implementation method, and the present invention further provides a multi-NTP server timing implementation system, where the multi-NTP server timing implementation system includes a module for executing the multi-NTP server timing implementation method, and the system may be configured in a terminal such as a computer device, and by applying the multi-NTP server timing implementation system according to the present invention, NTP server times are obtained by setting multiple NTP server addresses, and after failure of obtaining one of the NTP server times, NTP server times may be obtained according to another NTP server address, and in cooperation with comparing the NTP server times with local times, finally, a setting operation of local times is implemented, so as to effectively improve system fault tolerance and enhance reliability of time synchronization between an NTP server and the terminal, the quality of the product is greatly improved, the abnormal phenomenon of asynchronous broadcast sound is effectively reduced, and the stability of the product is improved.
Specifically, as shown in fig. 3, the multi NTP server timing implementation system includes an NTP server list module 110, a time synchronization component module 120, and an analysis and judgment module 130.
An NTP server list module 110, configured to establish an NTP server list;
a time synchronization component module 120, configured to select an NTP server address from the NTP server list, and obtain an NTP server time corresponding to the NTP server address; and
for replacing the local time with NTP server time; wherein, the local time is the real-time terminal time;
an analyzing and judging module 130, configured to judge whether time acquisition of the NTP server is successful, and when time acquisition of the NTP server is unsuccessful, the time synchronization component module 120 selects another NTP server address from the NTP server list to acquire another NTP server time;
and for comparing the current NTP server time with the local time, and when the absolute value of the difference between the current NTP server time and the local time is not higher than a preset value, the time synchronization component module 120 replaces the local time with the current NTP server time; when the absolute value of the difference between the current NTP server time and the local time is higher than the preset value, the time synchronization component module 120 selects another NTP server address from the NTP server list to acquire another NTP server time; wherein, the current NTP server time is the real-time NTP server time successfully acquired by the time synchronization component module 120.
When the DNS service of a service operator has a problem, the NTP server with the IP address can still normally access; when the IP address of the NTP server is changed, the NTP server with the domain name address can still normally access, and the condition that the NTP server cannot access through the domain name address or the DNS service of a service operator has problems is avoided, so that the utilization efficiency of the NTP server is effectively improved, and the fault tolerance of the system is effectively improved.
If the time synchronization component module 120 does not access the NTP server through the NTP server address, the time synchronization component module 120 may not normally obtain the time of the NTP server, and further, the time of the NTP server may not be synchronized to each broadcast terminal, so that the time of each broadcast terminal may not be synchronized; at this time, the time synchronization component module 120 is required to select another NTP server address from the NTP server list again to obtain another NTP server time, so that the reliability is high, and the timing effect of the broadcast terminal cannot be affected when some NTP servers cannot be accessed.
Fig. 4 is a block diagram of a second multi-NTP server timing implementation system according to an embodiment of the present invention. As shown in fig. 4, the timing implementation system for multiple NTP servers provided in this embodiment further includes a counting module 140, configured to set kcount to 0, and add 1 to the kcount count when an absolute value of a difference between the current NTP server time and the local time is higher than a preset value, that is, kcount to kcount + 1.
In one embodiment, the parsing and determining module 130 is further configured to determine whether the kcount is lower than a preset number N, and when the kcount is lower than the preset number N, the time synchronization component module 120 selects another NTP server address from the NTP server list to obtain another NTP server time; when kcount is not less than the preset number N, the time synchronization component module 120 replaces the local time with the current NTP server time.
Specifically, when the absolute value of the difference between the current NTP server time and the local time N consecutive times is higher than the preset value, in this embodiment, N is 3, it may be determined that the current NTP server time obtained by the time synchronization component module 120 is correct, and the local time is incorrect, and then the current NTP server time is set to each broadcast terminal, so as to replace the local time of each broadcast terminal, thereby ensuring the consistency of the broadcast sound of each broadcast terminal, and meanwhile, the fault tolerance is strong, even if the NTP server time has an error, the broadcast terminal time is not affected.
