Design of Fault Injector for Underwater Vehicle Sensors
2023 2nd International Conference on Innovations and Development of Information Technologies and Robotics (IDITR)(2023)
Abstract
Aiming at the problems of complex working conditions, diverse fault modes and high-test costs of the underwater vehicle, a fault injector is designed based on TMS320F28335 digital signal processor. By analyzing the functional requirements, the hardware functional modules and software workflow of the fault injector are designed. After that, a fault injection experimental verification platform is built, and the effectiveness of the basic functions of the fault injector is verified by taking the speed sensor of the underwater vehicle as an example. The results show that the fault injector can meet the fault injection requirements of different fault modes, fault injection nodes and fault injection time, which is of great significance to the reliability research of the underwater vehicle.
