A multi-node abnormal data linkage type acquisition method
By introducing a linkage alarm mechanism and a caching waiting mechanism into the radar system, the problem of data acquisition loss of multiple nodes caused by the abnormality of a single node was solved, realizing the synchronous acquisition and complete recording of abnormal data in the multi-node radar system, and improving the efficiency of problem analysis and troubleshooting.

AI Technical Summary
Technical Problem
In existing radar systems, data anomalies at a single node often cause other nodes to miss the optimal time for data acquisition, and the lack of a multi-node coordinated acquisition mechanism increases the complexity of problem analysis.
Method used
By adopting a linkage alarm mechanism and a cache waiting mechanism, when a data anomaly alarm occurs on any node, the linkage alarm information is promptly distributed to other nodes, and the data before and after the abnormal data is collected in the cache area.
Benefits of technology
It enables the synchronous acquisition of abnormal data in multi-node radar systems, improving the efficiency of problem analysis, troubleshooting, and location, and ensuring the complete recording of the abnormal data change process.

Abstract
The application provides a multi-node abnormal data linkage type acquisition method, which is mainly suitable for the technical field of radar system data acquisition. The current node receives data into a ring buffer pool; it is judged whether linkage alarm information is valid, if yes, abnormal data is acquired and stored; otherwise, it is judged whether the current data is abnormal according to preset criteria, if yes, the linkage alarm mechanism is triggered, the linkage alarm information is distributed to each processing node by the current node, and the abnormal data is acquired and stored; if no, the current node receives data into the ring buffer pool; finally, it is judged whether the acquisition stopping condition is met, if yes, the acquisition is stopped, and the linkage alarm information is set as invalid, otherwise, the abnormal data is re-acquired and stored. The application can effectively monitor and timely acquire the data of each node when the radar system has data abnormality, and greatly improves the efficiency of problem analysis, troubleshooting, positioning and solution of each processing node.
