Problems solved by technology

Under normal circumstances, the difference between the actual arrival time of the train and the time stipulated in the running timetable is tens of seconds or even a few minutes. Accurate to the second to reach the specified position point
[0006] When the high-speed railway trains are actually running, the maximum speed can reach more than 300 kilometers per hour, so they can travel more than 80 meters per second. If the error reaches one minute, there will be a deviation of nearly 5 kilometers. Or when the vehicle in front has an emergency stop, it is very easy to cause a rear-end collision

Embodiment 1

[0057] This embodiment provides a high-speed rail scheduling method that uses RFID technology to achieve precision to the second, such as figure 1 and figure 2 shown, including the following steps:

[0058] S1: Set up several RFID cards on the high-speed rail track, wherein each RFID card has a unique code, and there is a corresponding block area between two adjacent RFID cards. A reader / writer capable of data transmission with the RFID card on the high-speed rail track is installed on the high-speed rail train.

[0059] S2: Generate planning schedule:

[0060] Before the high-speed rail train is put into operation, the driver drives the high-speed rail train along the track line at a specified speed. During the driving process, the driving data is obtained every H seconds, and the driving data includes the driving distance S i , travel time t i , travel speed V i and RFID card code R i . The above-mentioned travel data are associated to form a planned schedule, wherei...

Embodiment 2

[0103] This embodiment provides a high-speed rail scheduling method and system accurate to the second using RFID technology, such as Image 6 shown, including:

[0104] RFID cards are set on high-speed rail tracks, each RFID card has a unique code, and there is a blocking area between two adjacent RFID cards.

[0105] The reader is set on the high-speed rail train, and it can perform data transmission with the RFID card on the high-speed rail track.

[0106] Planned timetable generation module: before the high-speed rail train is put into operation, the driver drives the high-speed rail train to run at a prescribed speed along the track line. During the running process, the driving data is obtained every H seconds, and the driving data includes driving Mileage S i , travel time t i , driving speed V i and RFID card code R i . 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 r...

Abstract

The present invention provides a high-speed rail scheduling method and system that utilizes RFID technology to achieve accuracy to the second. The data transmission between the RFID card and the reader can penetrate harsh environments such as snow, fog, ice, paint, and dirt, and the reading speed is extremely fast. Fast, so it can ensure that the dispatch of high-speed rail trains is both fast and accurate. At the same time, in the process of guiding the high-speed rail train to run according to the execution timetable, when the current mileage of the high-speed rail train does not coincide with the reference mileage corresponding to the current moment in the execution timetable, it can prompt the driver at what speed to travel in order to travel at the scheduled time. The time guarantee coincides with the reference position of the execution timetable. When the current mileage of the high-speed rail train coincides with the benchmark mileage stipulated in the execution timetable, it can also prompt the driver at what speed to continue to maintain the overlapping state in the future. The adoption of the above-mentioned solution in the present invention can ensure that the high-speed rail trains can truly realize the running according to the preset timetable accurate to the second.

Description

technical field [0001] The invention relates to the technical field of high-speed rail train dispatching, in particular to a high-speed rail dispatching method and system that utilizes RFID technology to achieve precision to the second. Background technique [0002] With the rapid development of society, the exchanges between cities are becoming more and more frequent. In order to shorten the travel time between people's cities, my country has carried out large-scale construction of high-speed railways and put them into operation. How to ensure the safe and punctual operation of high-speed railways has caused people's high focus on. [0003] At present, the train operation scheduling system of high-speed railway adopts the principle of automatic blocking and partitioning of traditional railways for scheduling. The so-called block partition is to use the track circuit to distinguish each track, and each track forms a block partition. Install a signal light or a virtual signa...
