Abstract
The invention discloses a system and a method for publishing information at a high speed railway platform. A planning schedule is stored in advance, and mileage which a train needs to travel in each 0.1 second is recorded in the planning schedule. Before actual operation, a running schedule is formed according to departure time and stopping time at each station of the train. The mileage which the train should travel at each 0.1 second is recorded in the running schedule. Through accurate-to-second scheduling of the train in a running process, the train can arrive at a next station in accurate-to-second mode when the train runs, and train arrival time which is accurate to second is published on an information board at the next arrival platform. The train arrives at the station in accurate-to-second mode according to rules of the running schedule, and therefore train arrival information published at the platform is accurate to second.
Description
Technical field
The present invention relates to High Speed Railway Trains dispatching technique field, be specifically related to a kind of high speed railway station platform information delivery system and method.
Background technology
Along with the fast development of society, intercity interchange is day by day frequent, come and go intercity hourage to shorten people, China has carried out large-scale high speed railway construction and has put into operation, in actual trip process, a comparatively outstanding contradiction is exactly cannot know when the train being about to arrive at a station can arrive the passenger that platform is waited for bus, passenger's ticket checking complete laggard enter platform place wait for bus, the time that frequent wait tens minutes is even longer, and in the process, passenger cannot know the information of the train being accurate to second, bring inconvenience to thus the go off daily of people.Therefore in prior art, a lot of document discloses the real-time traffic information how providing circuit bus by arranging notice board at platform place to the people waited for bus.But for the dispatching system of High Speed Railway Trains in prior art, can not ensure that train can be accurate to each station of arrival of second, therefore the relevant information entered the station for train that passenger provides at platform in prior art is inaccurate, and this mainly causes the scheduling inaccuracy of train in prior art.
Current high speed rail train operation dispatching system adopts the subregion principle of automatically closing up of traditional railway to carry out dispatching.So-called block section utilizes track circuit that each section of track regions is separated exactly, and every track section forms a block section.Starting point in each block section installs signal lamp or virtual signal lamp, when train enters the track of this block section, the signal lamp of this block section starting point sends out a warning immediately or by virtual signal lamp, red light phase is sent to control center and carries out processes and displays, when control center judges that the distance of this train of subsequent column spacing is less than or equal to personal distance, signal lamp red light phase is sent on the locomotive of the follow-up train being about to walk to by communication module by control center immediately, and alerting drivers stops immediately; When the distance of this train of subsequent column spacing is close to minimum safety interval distance, signal lamp amber light state is sent on the locomotive of the follow-up train being about to walk to by communication module by control center immediately, alerting drivers Reduced Speed Now; When the distance of this train of subsequent column spacing is greater than minimum safety interval distance, signal lamp green light phase to be sent to by communication module on the locomotive that is about to walk to follow-up train by control center, and prompting chaufeur travels with normal speed.
To sum up, chaufeur, in driving procedure, is all rely on the experience of chaufeur to drive.Chaufeur only just can proofread the time difference between the actual arrival time of train and regulation arrival time when rapid arrives approach website, carry out the adjustment of train running speed in the operational process that train is follow-up according to this time difference.Generally, show the actual arrival time of train and the time of running moment error that specifies at tens seconds even a few minutes, each bus stop of arrival being accurate to second cannot be accomplished, forwards platform passenger cannot be realized the information of arriving at a station being accurate to second is provided.
