Abstract

The invention discloses an interface simulation system and method of a CBTC (Communication Based Train Control) system based on discrete I / O (Input / Output) control. Theinterface simulation system includes: a relay; a data acquisition card; a trackside interface preprocessing module and a vehicle-mounted interface preprocessing module which can load and initialize the connection with a corresponding system according to the system of the tested equipment; an interface information conversion module which can collect the bidirectional digital signal and convert the bidirectional digital signal into a general data format; an interface information mapping execution module which can realize mapping from a physical state value of the tested equipment to a relay state value and mapping from the relay state value to a computer digital signal; a transponder message execution module which can realize dynamic calculation and real-time processing of the transponder; and a fault injection module which can realize simulation restoration of a fault scene through logic combination of relay states. According to the system an method, the interface adaptation with different systems can be realized, the better compatibility is realized, the interoperability of the interface layer is improved, and the cost of related tests can be reduced.

Description

technical field [0001] The invention relates to a CBTC system in a rail transit system, in particular to an interface simulation system and method of a CBTC system based on discrete I / O control. Background technique [0002] The CBTC system (Communication Based Train Control System, communication-based train control system) is the mainstream signal system used to realize rail transit train operation control. Before the CBTC system is put into operation, multiple rounds of tests are required to verify that the system requirements are fully covered and defect items All are discovered and shut down, ultimately ensuring the efficiency and security of the system and improving confidence in system security. [0003] At present, the mainstream method for testing the CBTC train control system in the rail transit system is to carry out indoor laboratory simulation tests and outdoor test line tests respectively. Compared with outdoor testing, indoor simulation has the advantages of l...
