The invention discloses a real-time soft bus implementation method for an intelligent rail transit system, and the method comprises the steps: defining a data type of interaction between a server and a communication front-end processor, the defined data type being a message structure body, and the message structure body comprising a message header and a message body; the professional subsystem respectively constructs at least one publishing end entity and / or at least one subscribing end entity, wherein the data type for communication between the publishing end entity and the corresponding subscribing end entity is a message structure body. According to the method, cross-process, cross-region and cross-platform efficient data distribution of the subsystems is realized, the subsystems only need to subscribe to data concerned by the subsystems or release data which can be provided by the subsystems, the subsystems and the subsystems do not need to concern the addresses and the number of the opposite sides, and spatial decoupling is realized.
Description
technical field [0001] The invention relates to the field of intelligent rail transit, in particular to a method for realizing a real-time soft bus for an intelligent rail transit system. Background technique [0002] The smart rail transit system (referred to as the smart rail transit system) is a comprehensive rail transit monitoring system with traffic as the core, which provides a strong guarantee for rail transit traffic safety. The system is huge in scale and involves many specialized subsystems. How to make these specialized subsystems coordinate and operate without interfering with each other is one of the key problems to be solved in the intelligent rail transit system. [0003] Various professional subsystems include automatic train monitoring system (ATS), public address system (PA), passenger information system (PIS), video surveillance system (CCTV), environment control system (BAS), automatic fare collection system (AFC) and fire alarm System (FAS), etc., ther...
