Embodiment Construction
[0033] The present invention will be described in detail below in conjunction with the accompanying drawings, and the features of the present invention will be further revealed in the following detailed description.
[0034] figure 1 It is a structural diagram of the urban rail CBTC signal system. like figure 1 As shown in , the automatic train supervision system (Automatic Train Supervision, referred to as ATS) communicates with multiple computer interlocking (Computer Interlocking, referred to as CI) systems, multiple zone controllers (ZoneController, referred to as ZC), and multiple Automatic Train Protection (ATP for short) / Automatic Train Operation (ATO for short) in-vehicle equipment communication ground coupling. As an example, figure 1 The middle ATS is connected to 5 CI interlocks (for example, CI interlock 1, ..., CI interlock 5). The five CI interlocks can be physically or logically distributed into two zones, and controlled by corresponding zone controllers (eg...

The invention discloses a method for realizing a configurable secure communication protocol for a train control system based on communication. The train control system based on communication comprises an application layer and a hardware driving layer / security layer. The method comprises the following steps: setting a configurable secure communication protocol layer comprising a configurable secure communication protocol stack and a function interface between the application layer and the security layer, so that the application layer can configure the configurable secure communication protocol stack by calling the function interface to support various secure communication protocols for the communication between a plurality of components of the train control system. The configurable secure communication protocol comprises RSSP-I, RSSP-II and other secure communication protocols, a series of other security check modes is further provided at the same time, and a user can define different security check combinations in a configuration manner so as to a butt joint with the existing secure communication protocols of other subsystems without changing codes.
Description
technical field [0001] The present invention relates to a communication-based train control (CBTC) system, and more particularly, to an implementation method of a configurable safety communication protocol in the CBTC system. Background technique [0002] The known or unknown characteristics of the communication between the internal subsystems of the urban rail CBTC signal system (not limited to this system) will affect the safety of each subsystem, and the data transmission process between each subsystem may be affected by network delays or Interference and other reasons lead to threats such as duplication, deletion, insertion, reordering, damage, delay and camouflage of communication data, and in an open network, illegal intrusion is more likely to occur. In order to avoid the above security threats, it is necessary to adopt a secure communication protocol in the communication process, and a verification mechanism needs to be added to ensure the authenticity, integrity, ti...
