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 system and method for fault injection of high-voltage digital signals. The system includes: fault injection equipment, a host computer and a power supply, the communication connection between the fault injection equipment and the host computer, and the connection between the power supply and the fault injection equipment; The fault injection device is used to receive the high-voltage digital signal sent by the high-voltage digital output device; to attenuate the high-voltage digital signal to obtain a low-voltage digital signal; to receive the electrical layer fault injection parameters sent by the host computer; to use the low-voltage digital signal and electrical layer fault injection parameters to generate a low-voltage electrical layer fault signal; under the high voltage output by the power supply, use the low-voltage electrical layer fault signal to generate a high-voltage electrical layer fault digital signal; send the high-voltage electrical layer fault digital signal to the high-voltage digital acquisition device. The invention realizes the electrical layer fault injection to the high-voltage digital quantity 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...
