Problems solved by technology
In this case, trains on different lines cannot achieve shared operation, which brings waste of resources and hinders the goal of sustainable development in our country
Redesigning the wayside controller according to interconnection standards to meet the needs of interconnection will also bring higher R&D costs and safety risks to various signal manufacturers

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the drawings.
[0031] The middleware adaptation method for trackside systems compatible with vehicle-mounted systems of different manufacturers of the present invention is based on the middleware system interface layer set in the trackside system, such as figure 2 As shown, a middleware system interface layer is designed in the trackside subsystem (MCU) to shield the differences in the on-board equipment of different manufacturers and reduce the modification of the core modules of the trackside equipment system, such as: mobile authorization module, train tracking module , Train communication module, train mode module, train command processing module, etc.
[0032] See figure 1 , The middleware adaptation method of the present invention includes:
[0033] Step S1. The middleware system interface layer maps the interconnection standard electronic map with the manufacturer's own track topology map to ach...

The invention discloses a middleware adaptation method for a trackside system to be compatible with vehicle-mounted systems of different manufacturers. Based on the interface layer of the middleware system in the trackside system, the middleware adaptation method includes: train position adaptation ; train mode adaptation; train state parameter adaptation; mobile authorization adaptation. Temporary speed limit function adaptation. The invention uses a common interface layer to convert information of vehicle-mounted systems of different manufacturers into information recognizable by trackside equipment, then processes the information and converts the processing results into information recognizable by vehicle-mounted systems of all manufacturers. It enables trains equipped with on-board equipment from different signal manufacturers to seamlessly interoperate and operate safely and reliably in one rail transit line equipped with trackside equipment from different signal manufacturers, avoiding the problems caused by large-scale modification of the existing system architecture Design cost and system risk.
Description
Technical field [0001] The invention relates to the field of interconnection and intercommunication between trackside equipment and vehicle-mounted equipment of a rail transit signal system. Background technique [0002] In the existing design, the trackside controller (MCU) in the rail transit signal system is one of the important components of the rail transit signal system. In the entire signal system, the trackside controller (MCU) communicates with the central control unit (CCU) and receives instructions from the central control unit, such as route arrangement instructions, track closing instructions, and temporary speed limit instructions. Feedback various information in the current control area, such as the real-time position of all trains in the current control area, route information, signal display information, etc. In addition, the trackside controller also communicates with the vehicle controller (VCU) to receive the real-time position of all trains in the current co...
