s4, the network management node performs AND operation on a power-on mark corresponding to the node in the power-on switch sequence table of the network management node and a wake-up mark corresponding to the node in the wake-up frame, and sends out a network management message when the operation result is 1; the intelligent network management module receives the network management message forwarded by the network communication module;
s5, the intelligent network management module collects network management messages of all network management nodes and performs an abnormal awakening error checking mechanism;
s6, after the awakening is finished, the whole vehicle needs to be dormant; the intelligent network management module adopts a fast sending mechanism, sends a wake-up frame to the network management node through the network communication module, and can perform power-off processing on the I-type network management node only when wake-up information in a network management node network management message acquired by the intelligent network management module is a dormancy condition and is met.
10. The method according to claim 9, wherein in S5, the mechanism for checking the abnormal wake-up error comprises:
s51, the network management nodes in the list of the network management nodes to be awakened by the intelligent network management module are not awakened, the intelligent network management module executes awakening again to the network management nodes which are not awakened, the network management nodes are not awakened after repeating N times, N is less than or equal to 5 and can be calibrated, and the intelligent network management module reports awakening abnormity to a network, a background or a user mobile client;
s52, when network management nodes which are not included in a network management node list required to be awakened by the intelligent network management module are awakened, the vehicle-mounted intelligent network management gateway system checks the power-on condition and the awakening frame sending condition of the awakened abnormal network management nodes; if the abnormal network management node is a class II network management node, if the vehicle-mounted intelligent network management gateway system does not send a wake-up frame to the abnormal node, the intelligent network management module reports the wake-up abnormality to a network, a background or a user mobile client.
