Example Embodiment
[0042] Example one
[0043] See figure 1 with figure 2 , figure 1 Is a schematic structural diagram of a distributed network clock synchronization system provided by an embodiment of the present invention; figure 2 This is a schematic structural diagram of a slave device of a distributed network clock synchronization system provided by an embodiment of the present invention. A distributed network clock synchronization system includes:
[0044] Clock source, used to send clock synchronization information;
[0045] At least one level of slave device is connected to the clock source level by level for receiving the clock synchronization information level by level and completing clock synchronization; wherein,
[0046] The clock source and the at least one level of slave device are nodes in a distributed network clock synchronization system.
[0047] Preferably, the slave device includes: an interface module, a link delay module, a time difference module, and a synchronization module; wh...
Example Embodiment
[0070] Example two
[0071] Please continue to see figure 1 with figure 2 , figure 1 Is a schematic structural diagram of a distributed network clock synchronization system provided by an embodiment of the present invention; figure 2 This is a schematic structural diagram of a slave device of a distributed network clock synchronization system provided by an embodiment of the present invention. This embodiment further describes the clock synchronization system in detail on the basis of the foregoing embodiment. The distributed network is formed by interconnecting nodes distributed in different locations and with multiple terminals, and has high reliability. At the same time, the network is easy to expand. A distributed network clock synchronization system, such as figure 1 As shown, N is a natural number greater than or equal to 1. The distributed network clock synchronization system includes a clock source and at least one level of slave devices, where the clock source is used ...

[0081] Example three
[0082] Please continue to see image 3 with Figure 4 , image 3 It is a schematic diagram of a delay measurement principle of a distributed network clock synchronization system provided by an embodiment of the present invention; Figure 4 This is a schematic diagram of the time difference principle of a distributed network clock synchronization system provided by an embodiment of the present invention. This embodiment provides a detailed description of the time perception module and its time synchronization system on the basis of the foregoing embodiment.
[0083] Distributed network is interconnected by nodes distributed in different locations and with multiple terminals. Any point in the network is connected to at least two lines. When any one of the lines fails, the communication can be transferred to other links to complete, which has high reliability. At the same time, the network is easy to expand.
[0084] Preferably, all nodes in the distributed net...
