Description
Technical field
The invention belongs to track traffic control technology field, a kind of method of simplifying Introduction of Train Operation Control System of special design.
Background technology
Rail Transit System mainly comprises railway and urban track traffic (hereinafter to be referred as city rail).In recent years, new Introduction of Train Operation Control System, as be applied to Train operation control system (the Chinese Train Control System of railway, CTCS) and be applied to city rail based on communication train operation control system (Communication Based Train Control System, CBTC) arise at the historic moment, for railway high speed and city rail densification, low compartmentation provide solid technical foundation and foundation for security.
By analyzing current CTCS and CBTC system architecture, be not difficult to find that these systems are all to continue to use the thinking of classical signal equipment design, for different running control function, adopt different subsystems, based on superposing type principle, realize whole system.
Such as: CTCS-2 level ground system comprises the computer interlock CBI, train operation TCC of control center and is controlled by its track circuit, trackside electronic unit LEU(containing active balise) etc., as shown in Figure 1; CTCS-2 level onboard system comprises that on-vehicle safety computing machine VC(is containing the distance measurement function that tests the speed), responser information receiving module BTM, track circuit information receiving element TCR, man machine operation interface DMI etc., as shown in Figure 2.

The benefit that realizes in the manner described above Introduction of Train Operation Control System maximum is that between each subsystem, boundary is clearly demarcated, can as much as possible not revise or the original subsystem of minimal modifications, reduce the work capacity of research and development, test, confirmation, checking and the safety assessment etc. therefore brought, reduce and occur wrong possibility.
But the shortcoming that realizes in the manner described above Introduction of Train Operation Control System is also apparent.First, do like this and can cause train operation control system to contain a lot of subsystems, complex structure, number of devices is many, and according to the groundwork of reliability, system architecture is more complicated, and number of devices is more, and MTBF is lower for its system.Even if whole system meets associated safety standard, reach corresponding safety integrity level (SIL) requirement, due to system, MTBF is low, can break down more continually and cause system recovery time elongated, not only reduce running efficiency of system, but also easily bring out other grave accident, track traffic grave accident be in recent years all much occur during breakdown of equipment just fully proved this point.
Secondly, owing to there being many subsystems, mutual coordination between subsystem (by communication) can take a large amount of software resource of each subsystem, and simultaneously again because there being electromagnetic interference, reliable, secure data communication between subsystem also need software, hardware resource outside occupying volume.
Finally, equipment is more, and the problems such as the space hold bringing, energy consumption are large, heat radiation are more difficult to process, and especially these problems of mobile unit are more outstanding.
Therefore, be necessary very much the method for research simplification Introduction of Train Operation Control System structure decrease number of devices.
Computer hardware technique develop rapidly in recent years.CPU is more and more towards future developments such as multinucleation, low power consumption, support are virtual, and its comprehensive treatment capability is more and more stronger, and the function that needs in the past a plurality of CPU to process is completed and become a reality by single cpu now.The develop rapidly of the technology such as while internal memory, disk, network, also makes the processing speed of computing machine and processing capacity also more and more strong, and these are implemented the present invention.
