A subway dispatching method and system based on rfid technology

Abstract

The invention provides a subway dispatching method and system based on the RFID technology. Data transmission between an RFRID card and a reader-writer can penetrate through snow, fog, ice, coatings, dust and other severe environments, the reading speed is extremely high, it can be guaranteed that a subway train is dispatched rapidly and accurately, and when a transponder breaks down, the complementation function can be achieved. Meanwhile, when the subway train is guided to run according to a running schedule, a driver can be reminded of the driving speed at which the train can coincide with the reference position of the running schedule within the preset time. By means of the scheme, it can be guaranteed that the subway train can really travel accurate to the second according to the preset time schedule. Due to the fact that each subway can accurately run according to the regulated time schedule, even though the departure interval is dense, the running time interval between different shifts of trains can be guaranteed, and rear-end collision accidents can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of subway train dispatching, in particular to a subway dispatching method and system based on RFID technology. 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 send th...

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 safe distance, it is normal driving. The error of the planned time is generally tens of seconds to several minutes, and 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 arrives at the specified location point 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.
