Integrated train control backboard

Abstract

The invention relates to the technical field of train control, and discloses an integrated train control backboard to improve the expansibility and flexibility of a system. At least more than two slotpositions are designed according to the same signal, and a signal line for connecting each slot position comprises a power management bus, an Ethernet bus, a CPCI bus and a serial bus. The serial busand the CPCI bus are respectively used as a backup data communication bus of the Ethernet bus. The backboard is fixedly provided with at least one power supply management bus which is connected withthe backboard. Ethernet bus, wherein the backboard server is used for integrating a CPCI bus and a serial bus and has a scheduling function of each bus. The method is used for supervising hot plug andprogram loading of the expansion cards inserted into the slots, setting and supervising selection and switching of communication buses among the expansion cards inserted into the slots after the expansion cards pass safety certification, dynamically constructing an Ethernet multi-master-control mode based on application control and intelligently switching a CPCI master control module.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to an integrated train control backplane. Background technique [0002] In the field of communication technology, most large-scale communication equipment adopts a distributed system architecture to build its system, and the system generally includes important components such as main control cards, backplanes, and line cards. The connection between the main control card and the line card is realized through the wiring of the backplane, while the connections between various board cards and the backplane are realized through connectors. [0003] On the one hand, the existing chassis bus generally adopts master-slave control, such as CPCI (Compact Peripheral Component Interconnect, Compact PCI). When the board fails, the entire chassis system will be paralyzed. At the same time, in the existing chassis structure, the data transmission between boards is often limited to the only...

Problems solved by technology

[0003] On the one hand, the existing chassis bus generally adopts master-slave control, such as CPCI (Compact Peripheral Component Interconnect, Compact PCI). When the board fails, it will lead to the paralysis of the entire chassis system

At the same time, in the existing chassis structure, the data transmission between boards is often limited to the only data exchange mode, and complex mechanisms such as monitoring and allocation scheduling are required to avoid data conflicts; and the independence of each slave control board is poor, due to its function Different, the bus corresponding to each slot is different, resulting in that different slave control boards can only be installed in fixed slots, and cannot be mixed, and increase the design difficulty and manufacturing cost of the backplane bus, and the scalability is poor
