The invention includes a distributed synchronous fault wave recording method based on short-distance communication. The method comprises the steps that: the periodic clock synchronization on a masternode and multiple associated scattered slave nodes are carried out, the real-time recording is carried out on the multiple associated scattered slave nodes with the completion of clock synchronization, the slave nodes upload a fault time identifier to the master node when any slave node detects a fault, the master node receives the fault time identifier and broadcasts record-locked identifiers tothe corresponding multiple decentralized slave nodes, the decentralized slave nodes receive the fault time identifier sent by the master node and then stop recording, and send and freeze recorded dataand sends a confirmation identifier back to the master node, and the master node calls fault waveform data of the scattered slave nodes according to a fault time period. The method has the advantagesthat the requirements for a platform and a device are low, the realization is easy, the data flow is small, physical and secondary side physical cable connection are not needed, the project implementation is simple, the cost is low, the real-time performance and storage of the recorded data are ensured by a double-buffer architecture.
