Abstract

The invention discloses an electromechanical product software reliability evaluation method based on environmental failure injection. The method is characterized by including the step: firstly, determining four scene elements of environmental failure injection scene modeling. Particularly, environmental failure injection scene model elements are represented by four tuples {IB, IT, IL and ID}, thefour tuples particularly include a failure injection behavior IB (Inject Behavior), failure injection time IT (Inject Time), a failure injection location IL (Inject Location) and failure injection data ID (Inject Data), wherein the failure injection behavior includes an impacting behavior and a waiting behavior, the failure injection time is generated by the aid of uniform distribution or normal distribution, and the failure injection location comprises a memory and a register and is generated by the aid of uniform distribution or normal distribution. The method is simple and ingenious in design, and electromechanical product software reliability is accurately evaluated in a complex external environment in reality.

Description

technical field [0001] The present invention relates to a software reliability evaluation method for electromechanical products based on environmental fault injection, and relates to the technical field of software reliability, in particular to a software reliability evaluation method for electromechanical products based on environmental fault injection. By designing the environmental fault injection scene, automatic Execute scenarios, collect failure data, and evaluate software reliability based on failure data. Background technique [0002] As the core component of the equipment system, the software of electromechanical products has a very harsh and complex external operating environment, including complex electromagnetic and natural environments. Complex external environments usually cause interference to the operation of electromechanical product software and cause failures, such as high radiation and electromagnetic interference that penetrate deep into the interior of ...
