The sub-nodes are arranged on the inner side of the guard rail stand column according to a preset distance, and are communicated with the main node after being connected in series; each sub-node monitors abnormal vibration of the guard rail through an integrated intelligent learning algorithm;

the master node is used for receiving abnormal vibration monitoring information sent by the child nodes within the jurisdiction range and sending the abnormal vibration monitoring information to the central node;

the central node is used for collecting the abnormal vibration monitoring information sent by each main node and sending the abnormal vibration monitoring information to a monitoring platform;

And the child nodes process the dormant state when the condition that the guard rail has no abnormal vibration is monitored. The power supply management module controls the power supply of the child node, so that the child node processes a dormant state, and electric energy is saved. Each child node can be used as a relay node, and when the communication distance of the child node exceeds the maximum data transmission distance, other child nodes can forward the data of the current child node to the child node instead.
