| Summary: | There are currently no appropriate methods to find CNC system software defects and eliminate hidden dangers. In order to improve CNC system reliability, the architecture expansion-based fault location method in CNC system software was proposed in this paper. The failure of CNC system software was 619 analysed, the expansion method of CNC system software architecture was proposed and the expansion component was established. The software data morphology information and running path were monitored and recorded, the failure pathway was obtained and a similar path set algorithm was adopted to generate the similar pathway set of the fault path. A least squares SVM-based suspicion model was established to determine the fault statement, eliminate faults and position the software fault in the level of the CNC system structure. Fault location experimentation was conducted in the multi-axis movement control card PCI-7344. The experiment’s result shows that the method proposed avoided the repeated testing and debugging by programmers. Without being limited by artificial factors and levels, it is a reliable method of CNC system software fault location. |
