The invention relates to the technical field of urban public transport management and control, in particular to an intelligent rail train intersection priority system with redundancy setting. The intelligent rail train intersection priority system with redundancy setting comprises vehicle-mounted equipment and ground equipment, wherein the vehicle-mounted equipment is installed on an intelligent rail train and sends vehicle priority request information to the ground equipment; the ground equipment executes a priority strategy and sends a priority processing result to the vehicle-mounted equipment; and two redundant communication channels are arranged between the vehicle-mounted equipment and the ground equipment to carry out vehicle priority request. According to the invention, a traffic signal controller can be ensured to acquire the vehicle approaching information in time and provide the priority passage service, and a set of independent priority request unit is redundantly arrangedand is used for sending the priority request information to the traffic signal controller under the abnormal condition, so that the passage efficiency and reliability of the intelligent rail train atthe intersection are improved.
Description
technical field [0001] The invention relates to the technical field of urban public traffic management and control, and more specifically, relates to a redundantly set intelligent rail train crossing priority system. Background technique [0002] As the problem of urban traffic congestion becomes increasingly prominent, a variety of public transportation solutions have been proposed, including subways, BRT systems, light rails, and intelligent rail trains. [0003] Among them, the intelligent rail express system with intelligent rail trains as the core vehicle has the advantages of short construction period, small infrastructure investment, high urban adaptability, and strong comprehensive transportation capacity, and has a good application prospect. [0004] Smart rail trains adopt high-speed rail flexible marshalling, and use "virtual track following control" technology to run on a predetermined "virtual track". It has the characteristics of zero emission and pollution-fre...
