With the increasing complexity of modern aircraft electro-mechanical (EM) systems, the Electro-Mechanical Management Computer (EMMC) has become a core control unit that directly impacts aircraft safety and reliability. Traditional testing methods often rely on physical system verification, which is time-consuming, costly, and unable to simulate complex integrated conditions. To address these challenges, the Electro-Mechanical Management Computer Universal Test Solution was developed. By constructing a virtual integrated environment that combines EM subsystems with related avionics, the system enables comprehensive simulation and testing of the EMMC under various operating conditions, supporting design validation, integration testing, and pre-delivery verification.

The solution provides full verification of EMMC functions and performance. Externally, the EMMC interfaces with avionics via the 1553B bus, and internally, it connects with fuel, environmental control, and other EM subsystems through RS422, analog, and digital interfaces. The system can simulate these interactions, supporting multiple EMMC models for development verification, integrated testing, and batch evaluation, thus meeting the complex requirements of modern aircraft EM system development.

Built on the HRT Hardware-in-the-Loop (HIL) simulation platform, the system features dynamic testing capabilities, introducing simulated models to closely replicate real operational conditions and enhance the reliability of test results. The platform provides automated testing functionality, allowing users to define test cases via scripts, execute them automatically, collect real-time data, perform analysis, and generate reports, significantly improving testing efficiency while minimizing human errors. Fault alert functionality allows sensitive signals to be monitored with threshold triggers, providing graded warnings for rapid fault identification and analysis.

Functionally, the solution supports multi-disciplinary co-simulation, integrating AMESim for EM system modeling with Matlab/Simulink for avionics system modeling to create a complete EM-avionics integrated simulation environment. ICD management capabilities allow manual entry or automated import of test-related ICD information, storing it in a database and exporting XML files for test control software support. The platform provides static testing for signal excitation, display, and analysis, while dynamic testing introduces simulation models to emulate real external environments. Automated test cases can be configured, generating test reports automatically, with user-defined inputs, outputs, and evaluation criteria. OPC communication interfaces allow rapid integration with third-party virtual instruments and SCADA software without programming.

This solution is suitable for aircraft manufacturers’ EM departments and auxiliary system design units. It supports functional interface testing during software development and automated verification testing before aircraft delivery, ensuring EMMC functionality, performance, and reliability, providing a solid foundation for safe aircraft operation.
