3results about How to "Implement redundant backup" patented technology

This invention relates to the field of aircraft health management technology, and discloses a system and method for implementing aircraft health management. The method collects health data from various monitoring points on the aircraft and status information from various ground processing nodes; then, based on this data and information, it processes the data to obtain target monitoring point clusters for each ground processing node; next, it preprocesses and configures the health data sent by the target monitoring point cluster, and then aggregates the cluster health data from each ground processing node and uploads it to a health database storage interface; finally, it synchronously obtains and analyzes the operational data from each storage interface through the health database storage interface, and performs distributed storage management of the cluster health data. This method can provide a scientific basis for aircraft maintenance, effectively improve aircraft safety, reliability, and operational efficiency, and reduce operating costs, thus having significant application value in the field of aircraft health management.

A fault-tolerant method for a dual-Y-shift 0° dual-redundant motor is disclosed, relating to the field of fault-tolerant motors. This invention addresses the problem that after a fault occurs in a dual-Y-shift 0° dual-redundant electric winch, the faulty winding needs to be located first and then disconnected, resulting in a lengthy fault-tolerant process. The fault-tolerant method for a dual-Y-shift 0° dual-redundant motor described in this invention decouples the motor and obtains the d- and q-axis voltage setpoints for both windings. These setpoints, along with current feedback values, are input to a d- and q-axis voltage disturbance observer to obtain estimated d- and q-axis voltage disturbances for both windings. The estimated voltage disturbance of the faulty winding is then superimposed onto the d- and q-axis voltage setpoints of the non-faulty winding, thus achieving fault-tolerant operation of the dual-Y-shift 0° dual-redundant motor.

This invention relates to the field of energy management technology, and discloses a distributed energy device collaborative system and its master control redundancy backup method and system. The method is applied to a system comprising at least two distributed energy device units with different functions interconnected via a local network. Each unit runs the same control software and has a unique device identifier. Based on the device identifier, a current master control device is elected according to preset rules. The current master control device periodically collects system data and generates and broadcasts synchronization data packets with verification information. The remaining devices receive and verify the data packets, update their local status upon successful verification, and continuously monitor the online status of the master control device. When the master control device is detected to be offline, a re-election event is triggered, electing a new master control device from the remaining online devices. This invention achieves dynamic redundancy backup of control roles through a distributed election and status synchronization mechanism, significantly improving system reliability, availability, and fault tolerance, while reducing system cost and complexity.
