Abstract: The pre-stacking ZPW-2000 coding technology of track circuit in the ordinary speed railway station has become the mainstream technology used in the reconstruction of existing railway stations or the construction of new stations, providing effective technical guarantee and safety barrier for the ordinary speed railway to achieve multiple speed increases. In this paper, the modeling and simulation of pre-stacking coding in the station is carried out by using Petri net, a discrete event system modeling tool, to simulate the prestacking sending coding process of the train during running in the station, so as to improve the security of coding.
Keywords: coding; Petri net; pre-stacking sending code; fail-safety principle
