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 of the intelligent fire hydrant is obtained in time. Time cost and hardware cost can be saved. And after the network is recovered, the NB-IoT mode message can be continuously adopted.
本申请涉及一种冗余通信模式下的智能消火栓故障节点报文方法，通过为每个节点配置冗余通信通道；确定故障节点，通过故障节点获取周围节点的报文信息；通过所述报文信息，从周围节点中识别出支持冗余通信以及远传通信故障状态的可用节点；建立所述故障节点与所述可用节点之间的冗余通信，建立后，故障节点通过所述可用节点进行报文。在出现报文故障时，消火栓通过冗余的蓝牙模块进行报文，利用蓝牙的近场通信功能，通过周围节点进行报文转发，及时将因故障延迟的待报数据和节点信息及时上报给后台/主机，避免信息延迟，及时获知智能消火栓的信息。可以节省时间成本和硬件成本。网络恢复后，可以继续采用NB‑IoT模式报文。
