Hardware-in-the-loop simulation device, system and method for fan

Abstract

The invention relates to the field of simulation and particularly relates to a hardware-in-the-loop simulation device, system and method for a fan. The device comprises a simulation computer and an acquisition conversion module. The simulation computer transmits simulation analog parameters to the acquisition conversion module through the Ethernet. The acquisition conversion module converts the simulation analog parameters to an IO signal and sends the signal to an external physical controller for acquisition processing. A physical controller processes the signal and sends a control signal to the acquisition conversion module. After data conversion, the acquisition conversion module sends data information to the simulation computer. The invention solves the technical problem of low efficiency, reliability and versatility of code execution in the prior art. Through the device, system and method of the invention, digital interaction between a mathematical simulation model and the outside can be achieved, such steps as code generating and downloading can be omitted, the process is simplified, and the efficiency is improved. The device, system and method can be widely applied to hardware-in-the-loop simulation of fans in various industries.
