Intelligent fire hydrant fault node message method in redundant communication mode

The invention relates to an intelligent fire hydrant fault node message method in a redundant communication mode. A redundant communication channel is configured for each node; determining a fault node, and obtaining message information of surrounding nodes through the fault node; identifying available nodes supporting redundant communication and remote communication fault states from the surrounding nodes through the message information; and establishing redundant communication between the fault node and the available node, and after the redundant communication is established, sending messages by the fault node through the available node. When a message fault occurs, the fire hydrant sends a message through the redundant Bluetooth module, the near field communication function of Bluetooth is utilized, the message is forwarded through surrounding nodes, to-be-reported data and node information delayed due to the fault are reported to a background/host in time, information delay is avoided, and the information
