Embodiment 1

[0038] figure 1 is a schematic diagram of the ISCS system structure, see figure 1 , ISCS includes: FAS, BAS, ACS, PA (public address), PIS (passenger information system) and CCTV (closed circuit television) and other subsystems, ISCS comprehensive automatic monitoring system, has the advantages of high integration and interconnection, ISCS will separate The monitoring functions of various weak current systems are deeply integrated, which is conducive to the coordination and linkage when emergencies occur. In addition, ISCS also has a communication interface with railway signaling systems, mainly ATS (Automatic Train Supervision). The ISCS system is deployed in the OCC (Operation Control Center). In the OOC, the dispatcher monitors and controls the entire line of trains and equipment through the ISCS.

[0039] Specifically, BAS is responsible for comprehensive and effective automatic monitoring and management of HVAC system equipment, water supply and drainage system equipmen...

Embodiment 2

[0056] Compared with the traditional automata, the timed automaton adds a time-constrained mechanism, and at the same time adds a diagram annotation state transition, which has a very good effect on expressing the time-constrained characteristics of a real-time system. It represents time using finite variables and annotates the state transition diagram with a constraint. Constraints can determine the transition conditions of the system. If the constraints are related to time, and the time variable is used to determine the timing of state transition, it is called time limit. In a real-time system, usually multiple timed automata work together to form a timed automaton network.

[0057] UPPAAL is jointly developed by Aalborg University in Sweden and Uppsala University in Denmark. It is a formal tool for constructing timed automata models based on timed automata theory. UPPAAL uses professional syntax to search the state space of the system model to verify the security, reachabi...

Abstract

The invention discloses a train fire linkage and modeling verification method. The train fire linkage and modeling verification method comprises the steps that a fire detection device of an FAS detects a fire of a train, a fire alarm host of the FAS determines a fire position, the FAS uploads fire information to a TCMS, the TCMS transmits the alarm information to an ISCS of an OCC through a train-ground wireless communication system, meanwhile, the TCMS analyzes the fire position information contained in the fire information and controls the camera of the CCTV at the corresponding position, the picture of the camera is synchronized to the ISCS, and the OCC judges whether the fire occurs in combination with the alarm information and the picture of the camera and correspondingly executes the reset of a fire false alarm system or starts fire evacuation. According to the train fire linkage and modeling verification method, a timed automaton network is established based on a UPPAAL tool, and a train fire linkage method is described and verified. The subsystems of the TCMS and the ISCS can be linked reliably, system paralysis caused by errors of processes and linkage logic is avoided, and train running safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of train safety monitoring, in particular to a train fire linkage and modeling verification method. Background technique [0002] The automation of urban rail transit lines is getting higher and higher, especially the fully automatic driving trains, which have high operating efficiency and can effectively reduce the costs of the entire life cycle, which is an important direction for the development of urban rail transit in my country. There is a big difference between highly automated train operation scenarios and non-automatic operating lines, which put forward higher requirements for traffic organization and emergency response under abnormal conditions, and the execution efficiency of dispatching operations must be further improved to ensure that the operating lines driving safety. For example, in a fully automatic driving line, since there are no personnel on the train, once a dangerous situation such as...
