A2, judging whether the first CNC has a fault or not in the communication process;

the CUC determines whether the first CNC has a failure during communication with the first CNC, and the determination process may be continuously performed or periodically performed.

And A3, if the first CNC is determined to have a fault, switching to the communication with the second CNC.

If the CUC judges that the first CNC breaks down, the first CNC cannot normally work at the moment, therefore, the CUC is switched to be communicated with the second CNC, the user requirement to be collected is sent to the second CNC to be processed, and therefore stability and reliability of the TSN are guaranteed.

Correspondingly, if the CUC judges that the first CNC does not have a fault, the first CNC can normally work at the moment, and therefore the CUC can continue to communicate with the first CNC, and user requirements to be collected are sent to the first CNC to be processed.

The embodiment provides a network communication method, wherein a CUC determines whether a first CNC fails in a communication process with the first CNC, if so, the CUC switches to communicate with a second CNC, otherwise, the CUC continues to communicate with the first CNC, so that user requirements collected by the CUC can be timely processed, and stability and reliability of a TSN are ensured.

Specifically, the CUC may continuously/periodically send a first preset signal to the first CNC, the first preset signal being similar to the dog feeding signal.

If the first CNC is in a normal working state, the first CNC returns a corresponding first response signal to the CUC after receiving the first preset signal, so that the CUC knows that the first CNC is in the normal working state according to the first response signal.

Correspondingly, if the first CNC is in a failure state, the first CNC may not receive the first preset signal or return a corresponding first response signal to the CUC, and therefore, if the CUC does not receive the first response signal, the CUC may determine that the first CNC has a failure.

In this embodiment, the CUC may send a first preset signal to the first CNC, and determine whether the first CNC has a fault by determining whether the corresponding first response signal is received, so as to accurately obtain a working state of the first CNC.

Correspondingly, if the bridge determines that the first CNC does not have a fault, it indicates that the first CNC can normally operate at this time, and therefore, the bridge can continue to communicate with the first CNC, i.e., obtain the network configuration information from the first CNC.

The embodiment provides a network communication method, wherein a network bridge judges whether a first CNC fails in a communication process with the first CNC, if so, the first CNC is switched to communicate with a second CNC, otherwise, the first CNC continues to communicate with the network bridge, so that the network bridge can accurately acquire network configuration information, and the stability and reliability of a TSN are further ensured.

If the first CNC is in a normal working state, the first CNC returns a corresponding second response signal to the bridge after receiving the second preset signal, so that the bridge knows that the first CNC is in the normal working state according to the second response signal.

Correspondingly, if the first CNC is in a failure state, the first CNC may not receive the second preset signal or may not return a corresponding second response signal to the bridge, and therefore, if the bridge does not receive the second response signal, the bridge may determine that the first CNC has a failure.

s5, the second CNC receives user requirements sent by the CUC, discovers network topology through a link discovery protocol, then calculates optimal network configuration information, and sends the optimal network configuration information to each network bridge through a NETCONF protocol;

s6, when the first CNC fault is recovered, the first CNC broadcasts a fault recovery message to the CUC, the second CNC and the bridge;

s7, switching the CUC to communicate with the first CNC, namely sending the user requirement to the first CNC; in addition, the bridge also switches to communicate with the first CNC;
