A hardware-in-the-loop simulation system and its communication method

Abstract

The application discloses a semi-physical simulation system and its communication method. The semi-physical simulation system includes a PC, a first physical physical layer device, a second physical physical layer device, and a semi-physical simulation interface. The PC includes virtual network simulation surroundings. The present invention uses the half-physical simulation interface to connect the first physical physical layer device, the second physical physical layer device and the virtual network simulation environment, and realizes the virtual data packet sent by the PC and the first physical physical layer device through the half-physical simulation interface. and the protocol conversion between the physical data packets sent by the second physical physical layer device, so as to realize the two-way information interaction between the network simulation system and the physical physical layer device, and realize the transmission of the terminal node by mapping the dual physical layer model of the node , Receiving and relaying and forwarding ad hoc network functions, enabling physical physical layer devices to participate in the network ad hoc process as terminal nodes, meeting the semi-physical simulation requirements of ad hoc networks.

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 (Hardware In The Loop, 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 make important modules Realized by hardware, it is 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 ...
