Simulation testing device and method of rail transit signal system

Abstract

The invention provides a simulation testing device and method of a rail transit signal system. The simulation testing device of the rail transit signal system comprises vehicle-mounted equipment, multiple ground equipment and secure communication protocol modules, wherein the vehicle-mounted equipment obtains vehicle-mounted data; the multiple ground equipment obtain ground data; the secure communication protocol modules are connected between the vehicle-mounted equipment and the ground equipment or between the ground equipment and the ground equipment, wherein the secure communication protocol modules receive and transmit the vehicle-mounted data and the ground data by using secure communication protocols. Compared with the prior art, the simulation testing device of the rail transit signal system has the advantages that the communication objects of the vehicle-mounted equipment or the ground equipment are changed into the secure communication protocol modules; the secure communication protocol modules convert the vehicle-mounted data and the ground data into data conforming to a secure communication protocol; the interconnection and intercommunication compatibility of a Communication Based Train Control (CBTC) system is improved; and meanwhile, the secure communication protocol modules can also encrypt the data to enhance the data communication security.

Description

technical field [0001] The invention relates to the field of rail traffic signals, in particular to a simulation test device and method for a rail traffic signal system. Background technique [0002] In urban rail transit, Communication Based Train Control (CBTC) is a train operation control system that uses high-precision train positioning, a large number of continuous two-way communication between trains and ground, and realizes safe control of trains through ground equipment and on-board equipment. , whose main task is to ensure the safe operation of trains within the lines controlled by the system. [0003] At present, urban rail transit is widely used in major cities. The CBTC system signal equipment used by each signal manufacturer is different. The signal manufacturers of different subway lines in each city may be different, and the equipment types and function implementation methods of each manufacturer may be quite different, resulting in incompatibility of signal ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, most subsystems of CBTC system signal equipment usually use User Datagram Protocol (UDP) for data communication, which is vulnerable to external interference and lacks effective information security defense measures

Some CBTC systems that have already realized the interconnection and interoperability of urban rail transit require different manufacturers to independently develop a new system that meets the corresponding standards, and the functional test of the system interconnection standard involves coordination and communication between two parties or even multiple parties. The development cycle is long, Poor compatibility and high cost
