Abstract

The present application provides a noise fault simulation method and apparatus, the method comprising: obtaining a noise fault simulation instruction, generating a noise signal corresponding to the noise fault simulation instruction, and obtaining an analog signal of an information source device; interfering with the analog signal by using the noise signal; and outputting an interference result signal to an information receiving device. It can be seen that the present application provides a scheme for automatically performing noise fault simulation according to a noise fault simulation instruction, and the scheme is not required to perform the noise fault simulation by manually inputting a fault, thereby overcoming various problems of a conventional manual mode, achieving high noise faultsimulation efficiency and providing a noise fault simulation test with high repeatability due to the time control in the automatic noise fault simulation process.

Description

technical field [0001] The present application belongs to the field of analog noise fault injection, and in particular relates to a noise fault simulation method and device. Background technique [0002] Analog signals are widely used in the field of rail transit, such as locomotive control consoles, line sensors and other places. However, the electromagnetic environment of such places is relatively complex, which can easily lead to noise superposition phenomenon at the analog signal output end, transmission line or receiving end. The superimposition of the transmission line or the receiving end and the analog signal will cause different degrees of noise interference in the train system, and even pose a threat to the operation of the entire train system. [0003] Therefore, for train equipment with analog signals, in the development stage, it is necessary to carry out anti-noise tests of single-device / multi-device analog signals, so that it can be used for single-device / mul...
