EA040964B1 - METHOD FOR TRAIN OPERATION CONTROL BASED ON PASSENGER FLOW DATA IN REAL TIME AND INTELLIGENT SYSTEM FOR ITS IMPLEMENTATION - Google Patents

Description

Technical field

The present invention relates to the field of train control, in particular to a train control method based on real-time passenger flow data and an intelligent system for implementing this method.

State of the art

In the prior art train control system, controllers manually determine whether trains need to be increased or canceled based on reports from station personnel or video recordings, and operate the trains through various scheduled operating patterns. The degree of reliance on manual control is extremely high, and changes are often not timely and inaccurate, which exacerbates the discrepancy between passenger traffic and vehicle capacity, and also easily causes delay in especially crowded places.

From the prior art patent document CN 104192177 B is known, which describes a method for automatically controlling the operation of city trains for rail transportation based on a discrete event model. In accordance with the invention, the train operation control system is considered as a discrete-event system and formal simulation is performed on it. The total delay time of trains and the number of delayed trains are used as indicators for decision making and selection of various control methods to correct train traffic. The dispatcher selects the adjustment mode according to the request at his human-machine interface (HMI) workstation and informs the train control system of the selected adjustment mode using a text-based data exchange format based on JavaScript (JSON). The train control system uses a message subscription mechanism and receives information about the arrival event and the departure event of the online train using the Common Object Request Broker Architecture (CORBA). The train arrival or departure event triggers the system to rapidly return train operation to a normal and orderly state based on the predetermined adjustment mode. The present invention is directed to adjusting the stop time of the train on the platform and the level of interval operation when there is a deviation in the train operation, so that the train can resume operation as soon as possible according to the planned schedule. However, this solution cannot solve the problem that the number of trains may be increased or trains canceled as station personnel change.

As shown in FIG. 2, the system includes three parts: a real-time passenger flow counting system based on video data on train filling and data from an automated fare system, a real-time passenger flow and transport capacity comparison system, and an intelligent train control system. The real-time passenger traffic counting system calculates the real-time passenger traffic based on video identification information, train filling information, automated fare calculation information, archive data, etc. The real-time comparison system of passenger traffic and transport capacity analyzes the need for the existing passenger traffic with the existing transport capacity of the line, and also determines the principle of transport capacity regulation depending on the current state of the device. The intelligent train control system adjusts the real-time operating pattern based on the real-time passenger traffic and the result of the matching system, and assigns or cancels trains, and provides the creation of a track plan with reference to the dispatch plan, and provides device information. The calculation and analysis of passenger traffic includes a system that provides a combination of data and consists of video identification and counting tools and an automated fare collection system, and the archived data base of passenger traffic provides an analysis of archive dynamics, while the calculated information is transmitted to the appropriate server for analyzing the correspondence between passenger traffic and vehicle capacity . The on-board system includes a train information management system, vehicle capacity information, and an on-board video identification and counting system, and on-board information is received through an on-board controller and transmitted to the corresponding passenger flow and vehicle capacity comparison analysis server of the center wirelessly for a ground train. The passenger flow-to-vehicle capacity matching analysis server further comprehensively analyzes the device failure information provided by the device information monitoring server, and then provides a proposal to increase or decrease the passenger flow. This proposal is confirmed from the dispatcher's workstation and then sent to the application server of the automatic work regulation system to adjust the work plan, and the final plan is transmitted to the train for execution by wireless communication for the ground train.

As part of the creation of the invention, an archived database of passenger traffic was created, based on previous operating experience. After the station receives significant traffic data through video and automated fare database, it is determined whether the significant traffic data is due to a malfunction of the device or if it is an exceptional and unusual case during the day, determined based on the archived database and information on the status of the device, and for this time period, the demand for passenger traffic is set in real time. The on-board system receives, via video and filling in, information about the possibility of the vehicle capacity of several trains at once, approaching the station in a certain direction.

After the station, the on-board information is sent to the corresponding center's passenger flow and vehicle capacity matching analysis server, the center server performs passenger flow estimation and real-time analysis to assign or cancel vehicle capacity based on this information, and determine the train to be assigned or canceled. , and the train route based on the location in the database server. The analysis result is sent to the dispatcher's workstation for confirmation.

After confirmation by the dispatcher, the proposed work plan is included in the existing operational scheme and transmitted to the on-board system using the train control command. The station performs the final adjustment of the trains.

Within the framework of the present invention, given that the existing solution is already equipped with devices related to the collection of video data, an automated fare collection system, train filling data and an automated train control system, as well as a wireless transmission device for a ground train, the system should additionally be equipped with at least several additional sets of video identification and counting servers and on-board video identification and counting servers (on each train), 1 set of historical passenger flow data and 1 set of passenger flow and vehicle capacity comparison analysis servers. In addition, the interface between the train filling system and the automated payment system has been increased.

In the intelligent operating pattern adjustment system, when the passenger flow does not match the capacity of the vehicle and a train needs to be assigned, one flight can be included in the existing operational pattern. The system requests the dispatcher. Once the controller confirms, the operational pattern adjustment can be completed in about 30 seconds. At this time, if the operation interval meets a certain condition, including

Claims (9)

niya, the command can be immediately sent to the train. The following cases are provided. 1. If a station with an unexpected passenger flow is a station with a depot, then the train standing on the line in the depot is put into operation in 30 s, i.e. when adjusting the operating plan. Based on the structural design of the station and the exit to the passenger platforms, from which trains go from the center and to it, the total time is about 2 minutes. 2. When the unexpected traffic station is not a depot station, using the design station arrangement as an example, the train needs to come from the depot to the station to ensure the vehicle capacity, which is about 3 minutes. In addition, the operation adjustment time is 30 seconds. So it takes 3.5 min to start transporting passengers. During a specific operation, the train assignment situation for operation and the real-time train operation situation can be further analyzed as needed, and the train route can be changed to adjust the vehicle capacity in a shorter time, thereby improving performance.
