| Abstract: | The paper comes up with a computer interlocking system based on ProfiBus field bus in accordance with the fact that there are a number of monitoring and control points in railway interlocking system, and that monitoring and control objects are widespread. It expounds the system in hardware and software, and especially expatiates on the achievement mechanism of double hot backup machine and dynamic switch technology over two modules. |
