Design and Development of IoT-based secure wireless network for control and configuration of Remote Hardware-In-Loop Simulation Test-Setup

Abstract

Hardware-in-loop simulation (HILS) is a unique platform validating avionics software and subsystems. This process takes place in the HILS laboratory, where multiple avionics systems are interconnected, with additional avionics subsystems remotely integrated into the simulation. It is essential that these systems be controlled, monitored, and operated automatically through a single point of command, control, and configuration, managed remotely via a centralized computer. To achieve this, an IoT-based wireless network has been designed and implemented for the control and configuration of both local and remotely situated subsystems within the HILS environment, aligning with Industry 4.0 standards for control and automation. Notably, this design operates without internet connectivity, allowing for secure and reliable remote operation and data transmission of avionics systems like actuators, inertial navigation systems (INS), or propulsion systems, even in harsh environments with zero human intervention. Given the sensitivity and high value of avionics subsystems within HILS—many of which are flight-worthy—it is crucial to protect the network from unauthorized access for multifunctional. This novel control and configuration system leverages Bluetooth interfaces, an Arduino board, and the nRF24L01 transmitter and receiver module for long-distance wireless communication, integrated with a user application built on the QT framework on the desktop. This paper presents the development of the hardware architecture and software, along with suggestions for future enhancements.
