Description

Technical Field

[0001] The present invention belongs to the technical field of control or regulation systems, and particularly relates to a distributed clock synchronization system and a control method thereof. Background Art

[0002] A distributed clock synchronization system is a system that controls scattered or distributed systems to operate uniformly or synchronously. Due to factors such as hardware differences and network delays in the scattered systems, the scattered systems cannot operate synchronously. For example, in a data center composed of multiple servers, these servers may be located in different places. If the multiple servers cannot operate synchronously, the data center cannot uniformly process the data in each system. In this way, the operation and management of data unity in the data center will be seriously affected.

[0003] In intelligent system management, systems located in different geographical locations or different places need to be uniformly managed to make each system operate synchronously. Using a distributed clock synchronization system helps to uniformly operate and manage each scattered system to make each system operate synchronously because the distributed clock synchronization system can monitor systems in different places. For example, when a system in a certain place or several places fails, the distributed clock synchronization system can control or monitor systems in different places within a short time. The distributed clock synchronization system can provide unified management for these scattered systems to ensure that the scattered or distributed systems can operate synchronously safely and stably. Summary of the Invention

[0004] The present invention provides a distributed clock synchronization system and a control method thereof, which are used to solve the technical problem of how to make distributed systems operate synchronously. The present invention uses the distributed clock synchronization system to monitor and control distributed systems in real time. As long as one or several systems in the distributed systems do not feedback signals or information to the distributed clock synchronization system, one or several systems in the distributed systems will stop operating. Until one or several systems in the distributed systems are replaced, then use the distributed clock synchronization system to monitor and control distributed systems in real time to achieve synchronous operation of distributed systems.

[0045] As Figure 2 shown, a control method for distributed clock synchronization includes the following steps:

[0046] Step 1): Each distributed system feeds back information to the distributed clock synchronization system;

[0047] Step 2): The distributed clock synchronization system monitors and controls whether each distributed system is operating normally; among them, the distributed clock synchronization system uses the signal matching method to monitor and control whether each distributed system is operating normally;

[0048] Step 3): The distributed clock synchronization system uses the signal dispersion method to determine whether each distributed system is operating normally; if each distributed system is operating normally, the distributed clock synchronization system monitors and controls each distributed system in real time; if one or several of the distributed systems are operating abnormally, the distributed clock synchronization system controls one or several of the distributed systems to stop operating;

[0049] Step 4): Replace one or more of the distributed systems that have stopped operating, and the distributed clock synchronization system then uses the signal matching monitoring method to monitor whether the replaced one or more distributed systems are operating normally;

[0050] Step 5): The distributed clock synchronization system controls each distributed system again;

[0051] Step 6): After each system in the distributed system runs normally, each system in the distributed system feeds back information to the distributed clock synchronization system.

[0052] Specifically, in step 1), each system in the distributed system feeds back information to the distributed clock synchronization system simultaneously to ensure that each system in the distributed system can be controlled by the distributed clock synchronization system in real time.

[0053] In step 2), for the signal matching method, the following steps are adopted:

[0054] Step A): The distributed clock synchronization system simultaneously discriminates the signals fed back by each system in the distributed system;

[0055] Step B): The distributed clock synchronization system classifies the signals fed back by each system in the distributed system according to the signals fed back by each system in the distributed system;

[0056] Step C): According to the signals fed back by each system in the distributed system after classification, the corresponding each system in the distributed system is found.

[0057] In addition, in step 2), the signal matching method can also be the following formula (1):

[0058] (1);

[0059] Wherein, is that the distributed clock synchronization system simultaneously discriminates the signals fed back by each system in the distributed system, is the signal fed back by the th system in the distributed system to the distributed clock synchronization system. The distributed system has ones;

[0061] is the th system in each system in the distributed system, represents the th system's position, is the signal fed back by the th system in the distributed system after classification. The corresponding th system in the distributed system is found.

[0062] In step 3), the signal dispersion method is adopted, which is the following formula (2):

[0063] (2);

[0064] Among them, is the signal fed back by the th distributed system to the distributed clock synchronization system. The distributed system has ones, is that the distributed clock synchronization system monitors the th distributed system to monitor whether the th distributed system feeds back a signal to the distributed clock synchronization system;

[0072] Based on Embodiment 2, in formula (1), the feedback signal of the first distributed system to the feedback signal of the th distributed system is fed back to the distributed clock synchronization system simultaneously. The distributed clock synchronization system internally sends simultaneous discrimination signals to simultaneously discriminate the signals simultaneously fed back by each distributed system, and also discriminates the positions of each distributed system. The positions of each system are thus determined. Through the function classifies the signals fed back by each distributed system to the distributed clock synchronization system. The signals fed back by each distributed system after classification, through … represent the positions of each system (because the positions of each distributed system have been discriminated), and thus each distributed system is correspondingly found.

If one or several distributed systems are operating abnormally (i.e., one or several distributed systems do not feed back signals to the distributed clock synchronization system), then the distributed clock synchronization system controls one or several distributed systems to stop operating. Embodiment 5

[0074] Based on all the above embodiments, the present invention utilizes the distributed clock synchronization system to monitor and control each distributed system in real time. As long as one or several systems in each distributed system do not feed back signals or information to the distributed clock synchronization system, then one or several distributed systems stop operating. Until one or several distributed systems are replaced, then the distributed clock synchronization system is used to monitor and control each distributed system or all systems in real time.
