The invention relates to the technical field of
rail transit automation control, in particular to a
software-defined lightweight distributed
rail transit station control system, which comprises a plug-in box, a power panel, a core board and a detachably installed
software-defined
peripheral interface board. The core board is connected with the
software-defined
peripheral interface board through a high-speed
bus and a low-speed
bus to realize real-
time data transmission and
configuration management, the software-defined
peripheral interface board is integrated with a
microprocessor, an interface circuit supports hot plug and
local logic operation, a Lua script engine is arranged in the software-defined peripheral interface board, graphical or script
programming is supported, and the software-defined peripheral interface board is connected with the software-defined peripheral interface board. The core board adopts an RISC-V architecture
microprocessor, has the functions of board card registration, configuration issuing, health monitoring and redundancy scheduling, and supports automatic networking and second-level takeover of fault nodes. The
system deploys an RT-Thread real-time
operating system, has a multi-node instruction conflict resolution mechanism, arbitrates the control right according to the priority and the
timestamp, and is suitable for multi-device cooperative control of the
rail transit station.
