| Abstract: | In railway signal computer interlocking system,interlocking is realized largely depending on controlling a great of data changed. So its data communication of trustiness and high efficiency is very important. The realizing method of inter-process communication of computer interlocking system is described in l.inux platform. The system has been used in certain railway bureau. This paper is mainly on the application of shared memory and semaphores. |
