Fault injection method and system based on remote procedure call (RPC)

Abstract

The invention relates to a fault injection method based on remote procedure call (RPC), which comprises the following steps: a fault injection front end providing fault information, and the fault information comprising information about a target single machine and information about a fault type; the remote procedure call RPC module packaging the fault information into a first communication frame and sends the fault information to the satellite simulator through a network; analyzing, by the satellite simulator, the first communication frame into information about a target single machine and information about a fault type, and generating single machine data according to the information about the target single machine and the information about the fault type; and packaging the stand-alone data into the second communication frame and sending the stand-alone data to the fault injection front end through the network. The invention also relates to a corresponding system. According to the invention, various satellite faults can be rapidly and efficiently simulated in a universal manner.

Description

technical field [0001] The present invention generally relates to the field of satellite simulators, and in particular relates to a fault injection method based on remote procedure call (RPC). In addition, the present invention also relates to a fault injection system based on remote procedure call (RPC). Background technique [0002] Due to the long-term operation of satellites in complex and harsh space environments, failures will inevitably occur, and some failures will affect the life and application of satellites. As a satellite simulation scheme, fault injection can effectively test the fault tolerance of the system, and has been widely used in the field of software testing. The basic idea of ​​fault injection is: the system is composed of the application and the environment. The environment contains all codes that do not belong to the application. The interface where the application interacts with the environment is the injection point of the fault. Faults that may ...

Problems solved by technology

However, the openness of fault injection tools is not good, and it is difficult to redevelop and expand on this basis

[0005] In order to inject any type of fault at any location, the current solution is to improve the versatility of the simulation platform, build a fault library that stores all possible communication link nodes according to the system configuration information, and implement any fault at any location through a multigroup or text model. Time-based fault injection, but this method only realizes the discrete faults of the target system link, and lacks the injection of continuous faults
