    摘要: The present invention provides a protector for vehicle-mounted black box, which comprise an inner shell body, an inner cover body, a data storage module and a cable; wherein, the data storage module is placed in the inner shell body; an opening end of the inner shell body is firmly connected to the inner cover body; one end of the cable is connected with the data storage module, and the other end running through the inner cover body for data transmission with the external; further comprises a damping material, the damping material being filled in a gap between the data storage module and the inner shell body; further comprises an outer shell body and an outer cover body; wherein, an opening end of the outer shell body is firmly connected to the outer cover body; the inner shell body is placed in the outer shell body; and the end of the cable that runs through the inner cover body extends out of the outer cover body for data transmission with the external; and further comprises a heat insulating material, the heat insulating material being filled in a gap between the inner shell body and the outer shell body; the protector for vehicle-mounted black box provided by the present disclosure solves the technical problem that the existing vehicle-mounted black box has weak impact resistance and high-temperature resistance which further make internal storage data easily destroyed, resulting in data loss, and thus has potential safety hazards in use.

    摘要: 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.
