Abstract:In order to satisfy the requirements of automatic fault injection of thermal resistance and thermocouple signals in equipment experiments, the fault injector of thermal resistance and thermocouple signals based on LXI is designed. By connecting the fault injector in series into the thermal resistance and thermocouple signals transmission lines, and simulating the fault types in the process of a variety of thermal resistance and thermocouple signals transmission, the simulation of the thermal resistance and thermocouple signals in the device under test can be achieved. With good promotional value and application prospects, the fault injector has been applied to the testability verification experiments in many types of equipment.
