Power secondary equipment network communication fault detection system and method

The invention relates to the technical field of network communication, and discloses a power secondary equipment network communication fault detection system and method, and the method comprises the steps: collecting a network data packet of a network communication layer of secondary equipment, analyzing the network data packet to obtain analysis data, and if a protocol type is not a preset protocol type, sending the analysis data to the secondary equipment; if yes, generating a first alarm signal according to the corresponding protocol type and the source-destination address; if yes, generating a second alarm signal according to the corresponding data content and the source address; flow peak value data in the network communication layer is also obtained, and if it is judged that the flow peak value data exceeds a preset flow threshold value, a flow alarm signal is generated; and a network storm fault is identified according to the traffic peak data, a network storm source corresponding to the network storm
