Hardware In The Loop simulation system and communication method therefor

Abstract

The application discloses a Hardware In The Loop (HITL) simulation system and a communication method therefor. The HITL simulation system includes a PC machine, a first entity physical layer device, a second entity physical layer device, and an HITL simulation interface. The PC machine comprises a virtual network simulation environment. The first entity physical layer device and the second entity physical layer device are connected with the virtual network simulation environment through the HITL simulation interface. The protocol conversion between virtual data packages sent by the PC machine and entity data packages sent by the first entity physical layer device and the second entity physical layer device is realized through the HITL simulation interface, so that the bi-directional information interaction between a network simulation system and the entity physical layer devices is realized. Ad hoc network functions of the sending, reception, and relay forwarding of terminal nodes are realized through a bi-physical layer model of mapping nodes. The entity physical layer devices, used as the terminal nodes, can participate in a network self-organization process, and satisfy an HITL simulation demand of the ad hoc network.

Description

technical field [0001] The present invention relates to the field of hardware-in-the-loop simulation technology, and more specifically, relates to a hardware-in-the-loop simulation system and a communication method thereof. Background technique [0002] Semi-physical simulation, also known as hardware in the loop simulation (HardwareInTheLoop, HITL), is to add physical objects to the software simulation environment, use virtualization technology to realize some modules / components in the simulation test with software, and realize important modules with hardware , as close as possible to the real result while reducing the investment. Half-in-the-loop network simulation is the realization of half-in-the-loop simulation on network simulation software. External network devices are mapped to special nodes or devices in the simulated network, and real data is used to conduct network simulation experiments. The data is fused into the simulated network, which can be more realistic I...

AI Technical Summary

Problems solved by technology

Since the terminal nodes do not participate in the self-organization process of the network, the existing hardware-in-the-loop simulation system cannot meet the requirements of the hardware-in-the-loop simulation for ad hoc networks
