Method and system capable of ensuring accurate running of subway train according to schedule

Abstract

The invention provides a method and system capable of ensuring accurate running of a subway train according to a schedule. In the process of guiding the subway train to run according to the running schedule, the fact that whether the running mileage of the subway train is coincided with the benchmark mileage recorded in the running schedule or not can be judged in real time. When the run mileage of the subway train is not coincided with the benchmark mileage corresponding to a current moment in the running schedule, that is lagging or advancing, a driver can be prompted to run at what speed to ensure that the current mileage of the subway train is coincided with the benchmark mileage of the running schedule in predetermined time. When the run mileage of the subway train is coincided with the benchmark mileage regulated in the running schedule, the driver can be prompted to run at what speed to continue to maintain the coinciding state. According to the method and system capable of ensuring the accurate running of the subway train according to the schedule, the true achievement of the subway train running which is accurate to second according to the preset schedule can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of subway train dispatching, in particular to a method and system capable of ensuring that subway trains run accurately according to a timetable. 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 automatic block area of ​​traditional railway for dispatching. That is to use the track circuit to form each section of track into a blocking area, and install a signal light or a virtual signal light at the starting point of the blocking area. When the train enters the section of track, the starting point signal light of the blocking ...

Problems solved by technology

[0004] The main problem of the above dispatching method is: the driver needs to rely on the driver’s experience to drive during the driving process. As long as the distance between the driver and the vehicle in front is greater than the safety distance, it is normal driving. The error of the planned time is generally tens of seconds to several minutes or more. It is impossible to realize that the time when the subway train arrives at each stop is accurate to the second, and it is even more impossible to realize that the subway train can arrive at the position specified in the current time in the running timetable in 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.
