Real-time Safety Diagnosis Algorithm of Train Operation Adjustment Plan
Zhili Liu · Zhongguo anquan kexue xuebao · 2004
The thain operation adjustment plan is a short-term train running plan edite d by railway dispatchers. When computers are used to assist railway dispatchers for dispatching, it is necessary at any time to diagnose the safety of the train operation adjustment plan to insure the feasibility of the computer-made plan . A safety diagnosis algorithm using train schedules data at dispatcher workstat ion is proposed. By generating occupation time lists of sections and stations fr om train schedules data, the original trains conflicts are turned into occupatio n conflicts of sections, stations, and station tracks. Logical expressions are p ut forward to judge the conflicts of sections and stations, and the stack method is used to judge the conflicts of station tracks. The algorithm has been put into p ractice.
