Problems solved by technology

[0003] At present, the fault injection for 110V digital signal generally only performs fault injection such as signal on-off, series impedance, and parallel impedance at the physical layer. Due to the high voltage value, the fault injection for the electrical layer has not been realized.

Abstract

The invention discloses a fault injection system and method for a high-voltage digital signal, and the system comprises fault injection equipment, an upper computer, and a power supply. The fault injection equipment is in communication connection with the upper computer, and the power supply is connected with the fault injection equipment. The fault injection equipment is used for receiving a high-voltage digital signal transmitted by high-voltage digital output equipment; carrying out the signal attenuation of the high-voltage digital signal, and obtaining a low-voltage digital signal; receiving electrical layer fault injection parameters transmitted by the upper computer; generating a low-voltage electrical layer fault signal through the low-voltage digital signal and the electrical layer fault injection parameters; generating a high-voltage electrical layer fault digital signal under the high voltage outputted by the power supply through the low-voltage electrical layer fault signal. and transmitting the high-voltage electrical layer fault digital signal to high-voltage digital collection equipment. The system achieves the electrical layer fault injection of a high-voltage digital signal.

Description

technical field [0001] The invention relates to the technical field of fault injection, in particular to a fault injection system and method for high-voltage digital signals. Background technique [0002] The fault injection of 110V digital signal can be applied to the debugging, testing and verification process of 110V digital acquisition equipment. By simulating the abnormality of the 110V digital signal, the response of the 110V digital acquisition equipment to the fault signal is tested, and the fault detection and fault handling capabilities of the 110V digital acquisition equipment are verified. [0003] At present, the fault injection for 110V digital signal is generally only the signal on-off, series impedance, parallel impedance and other fault injection of the physical layer. Due to the high voltage value, the fault injection of the electrical layer has not been realized. Contents of the invention [0004] In order to solve the above technical problems, embodime...
