Hardware-in-the-loop simulation platform and method for distributed fault diagnosis system of aero-engine

The invention discloses an aero-engine distributed fault diagnosis system hardware-in-the-loop simulation platform and method. The aero-engine distributed fault diagnosis system hardware-in-the-loop simulation platform comprises a main workstation, an aero-engine end, a fault diagnosis end and an intelligent node. The main workstation is connected with the aero-engine end through an RJ45 interface; the aero-engine end is connected with the fault diagnosis end through an RS232 serial port, and is connected with the intelligent node through the RS232 serial port and the A/D conversion interface; the fault diagnosis end is connected with the intelligent node through a TTCAN bus; the main work station completes fault diagnosis algorithm simulation verification, the aero-engine end is used for running an aero-engine component-level model program in real time, the fault diagnosis end is used for executing a fault diagnosis algorithm in real time, and the intelligent nodes are used for achieving intelligent node fun
