Aiming at the overspeed safety protection for high speed train operation,the core algorithm for train control onboard equipment was proposed.The overall structure included the EMU brake parameter input,line data input,safe distance reservation,mode curve generation and speed control processing.The algorithm was divided into four functional modules,such as brake parameter processing,line data processing,mode curve processing and speed control processing.The calculation formula for train control curves was the key to the core algorithm for train control onboard equipment.The calculation formulas for emergency brake curve,service brake curve,emergency brake triggering curve and service brake triggering curve were given respectively.The EMU braking experiments under different slope and line speed conditions were carried out in the real equipment laboratory.The braking distances of the mode curves of train control onboard equipment were measured,and comparative verification was conducted with the braking distances calculated by the simulation algorithm software.Results show that the error rate between the simulation results of the core algorithm for train control onboard equipment and the real-time monitoring results of real train control onboard equipment is less than 0.08%.The core algorithm for train control onboard equipment is applied to the compliance verification of the block section on newly built passenger dedicated line.It is verified that this method not only simplifies the configuration of simulation data,reduces the workload of tests and shortens the period of checking calculation,but also has a theoretical and practical value for the timely feedback of the checking calculation results of the compliance verification in block section.
