Description

Technical Field

[0001] The present application belongs to the technical field of integrated electromechanical management of large aircraft, and in particular relates to an efficient troubleshooting method and system for an integrated electromechanical system. Background Art

[0002] Aircraft electromechanical systems include dozens of subsystems, including power supply, hydraulics, environmental control, fuel, and landing gear. With the increasing integration of aircraft, the control design of each electromechanical system has been unified, forming an integrated electromechanical control architecture. The integrated electromechanical management system centrally implements functions such as automatic control, alarm information processing, screen page information processing, and fault reporting for each electromechanical system. For a typical four-engine aircraft, this often consists of 4,000 to 5,000 functional requirements and tens of thousands of signals. The design process of the integrated electromechanical management system involves rationally allocating tens of thousands of signals to form a signal flow diagram for each function, defining the electrical and bus ICDs for the relevant equipment. Common faults in the electromechanical system will have related alarms or abnormal display on the screen page, or a certain control function will fail. At this time, the electromechanical integrated management system needs to cooperate to find the relevant design documents, find the signal flow diagram of the function, and then find the electrical ICD and bus ICD of the relevant signal based on the signal flow diagram. Only then can the on-board data be monitored online according to the relevant bit definitions found to isolate the fault. This process often requires the use of electromechanical integrated management professionals, and involves multiple designers such as system supervisors, finished product supervisors, and ICD supervisors. It is time-consuming and labor-intensive. When a large number of models are equipped, the system's troubleshooting efficiency is greatly restricted.

[0032] Preferably, a different function ID is set for each system function in the function entry library to facilitate subsequent indexing.

[0033] Preferably, since the electromechanical integrated management system involves numerous acquisition and drive devices, each time a fault is to be repaired, it is necessary to know which device acquires the input sensor signal and which device outputs the control drive signal.

[0034] Therefore, in the function entry library, the sensor input device and control drive signal output device related to each function entry are obtained according to the system function data, and a signal flow graph is established. Then, the function ID is used for indexing, and a different device ID is established for each sensor input device and control drive signal output device.

[0035] Preferably, since the acquisition and output devices of the electromechanical integrated management system each involve hundreds of signals, it is necessary to define the connector number and pinhole number of the signal to locate it.

[0045] The system extracts the electrical pinhole number and bus bit definition based on the electrical signal ID and bus signal ID, and marks them on the functional flow chart.

[0046] In step S4, the extracted bus ICD information is collated to obtain the relevant electrical signal ID, bus signal ID, device ID, function ID, function item, and control implementation plan. This data is then generated and sent to the human-computer interface for visualization. This provides signals at all levels corresponding to the onboard fault, assisting troubleshooters in their troubleshooting efforts.
