Description

technical field [0001] The invention belongs to the technical field of aircraft electromechanical system testing, and in particular relates to a test and verification platform for an electromechanical integrated management system with load power simulation. Background technique [0002] At present, aircraft airborne electromechanical systems are developing in the direction of integration and multi-electricity. The electromechanical system of an aircraft is no longer a simple aggregation of various subsystems, but integrated into an organic whole. The electromechanical integrated management system with high-speed data bus, distributed multiprocessor technology and solid-state power relay driving load as the core is the controller for typical airborne electromechanical systems such as hydraulic system, landing gear, environmental control system, fuel system, and life-saving protection system. The part is physically and functionally integrated, and unified management, scientif...

AI Technical Summary

Problems solved by technology

[0003] Due to the high integration of the electromechanical integrated management system with the controller part of the airborne electromechanical system, the signal cross-linking between the electromechanical integrated management system and the airborne electromechanical system is complicated, and the coupling degree between the electromechanical integrated management system and the airborne electromechanical system is deepened, increasing the mechanical and electrical The failure rate of the integrated management system makes the test verification and integration of the electromechanical integrated management system more difficult, and the test requirements for the electromechanical integrated management system are higher

Moreover, the verification of overcurrent protection and tripping protection functions in the form of solid-state power relays to drive loads has also aggravated the difficulty of test verification of electromechanical integrated management systems.

[0004] In the past, the test verification mode of separate test of each electromechanical system product or joint test of a single electromechanical system can no longer meet the function and performance verification of the electromechanical integrated management system at this stage

Although the test of a single electromechanical system component can verify some interface requirements of a single component and the electromechanical integrated management system, it cannot judge and verify that a single onboard electromechanical system or even multiple electromechanical systems interact with the electromechanical integrated management system. The impact of access to the integrated management logic of the entire electromechanical integrated management system

The joint test of a single system can only verify the control logic and interaction relationship of the electromechanical integrated management system for a single system, and cannot realize the comprehensive test verification of the entire electromechanical system
