More Information
Summary:Disclosed is a computer-based interlocking system and a redundancy switching method based on the interlocking system. The computer-based interlocking system includes an interlocking subsystem; the interlocking subsystem includes an interlocking system I and an interlocking system II that are the same and are connected to each other; wherein each of the interlocking system I and the interlocking system II comprises two CPUs having the same hardware and adopting task-level synchronization; the two CPUs respectively run executable files generated by different compilers through compiling the same program codes. The system adopts heterogeneous software/hardware and program running starting times with a fixed difference to reduce the probability of occurrence of common-mode failures; thus, the development difficulty is lowered, the production efficiency is improved, and requirements for debugging and maintenance are lowered while reducing common-mode failures.
