Problems solved by technology

[0004] The main problems in the above dispatching method are: first, the driver cannot visually see whether the actual state of the front turnout is consistent with the state of the turnout required by the current route before approaching the turnout; Driving with experience, as long as the distance from the vehicle in front is greater than the safe distance, it is normal driving. Generally, the error between the actual running time and the planned time of the running timetable is generally more than tens of seconds to a few minutes, and it is impossible for the subway train to reach each stop. The time is accurate to the second, and it is impossible to realize that the subway train arrives at the specified location point accurate to the second
We know that the maximum speed of a subway train is about 90 kilometers per hour, and it can travel 25 meters in one second. If the error is 10 seconds, it will produce a deviation of 250 meters. When the departure interval is relatively close, rear-end collision accidents are very likely to occur.
[0005] Furthermore, when a subway train is in actual operation, its brakes generally require a certain distance. When any abnormality occurs on the track line in front, the driver cannot actively know the abnormal information in advance, and cannot find and deal with it in time. If an abnormality occurs on the track line The location of the situation is within the safe braking distance, even if emergency braking is too late, it is very likely to cause traffic accidents

Embodiment 1

[0061] Such as figure 1 As shown, the present embodiment provides a subway scheduling method that can ensure safe driving, such as figure 1 with figure 2 shown, including the following steps:

[0062] S1: Generate a planning schedule:

[0063] Before the subway train is put into operation, the driver drives the subway train along the track line at a prescribed speed. During the driving process, the driving data is obtained every 0.1s. The driving data includes the mileage S i , travel time t i , driving speed V i and transponder encoding C i ,Such as image 3 As shown, there is a blockage area between two adjacent transponders.

[0064] The above-mentioned travel data is associated to form a planned schedule, wherein the travel time t i As a reference time, the mileage S i As a reference mileage, the travel speed V i as a reference speed. Where i is an integer, and the mileage S i , travel time t i , driving speed V i and transponder encoding C i Respectively r...

Embodiment 2

[0110] This embodiment provides a subway dispatching system that can ensure safe driving, such as Image 6 shown, including:

[0111] Planning timetable generation module: before the subway train is put into operation, the driver drives the subway train to run at a prescribed speed along the track line. During the running process, the driving data is obtained every 0.1s, and the driving data includes driving Mileage S i , travel time t i , driving speed V i and transponder encoding C i , where there is a blockage area between two adjacent transponders; the above travel data is associated to form a planned timetable, wherein the travel time t i As a reference time, the mileage S i As a reference mileage, the travel speed V i as a reference speed;

[0112] The first image information acquisition module is used to acquire the image information at the key position: according to the transponder code C i and the mileage S of the subway train i Judging the distance between t...

Abstract

The invention provides a metro dispatching method and system capable of guaranteeing safe driving. In the process that a metro train is guided to run according to a running schedule, image information at the key position in the front portion is transmitted to the metro train; in addition, the image information can be compared with pre-stored standard image information, normal driving is carried out if the image information and the standard image information are coincident, and it is indicated that abnormal conditions occur in a front line if the image information and the standard image information are not coincident. A driver can be reminded to take prevention measures in advance, and road accidents can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of subway train dispatching, in particular to a subway dispatching method and system capable of ensuring safe driving. Background technique [0002] With the rapid growth of traffic demand, urban road traffic congestion is becoming more and more serious. In order to alleviate road traffic congestion, building subways is one of the main ways to meet people's traffic needs. How to ensure the safe and punctual operation of subways has attracted people's attention. [0003] At present, the subway train operation dispatching system adopts the principle of the automatic responder of the traditional railway for dispatching. That is to use the track circuit to form a transponder for each section of track, and install a signal light or a virtual signal light at the starting point of the transponder. When the train enters the track, the starting signal light of the transponder will immediately turn on the red light or...
