Description

Technical Field

[0001] This invention relates to the field of rail transit, and in particular to a method and system for automatically acquiring track current vehicle information in a centralized dispatching system. Background Technology

[0002] Track status refers to detailed statistical information and status data of all vehicles on a specific track at a specific point in time, including key information such as vehicle type, car number, load, cargo type, destination, and vehicle status. The accuracy of this information directly affects the operational efficiency and safety of the station and even the entire railway network.

[0003] Currently, the CTC (Centralized Traffic Control System) uses track availability information to automatically track vehicles between tracks, rationally allocate and utilize limited track resources, and effectively avoid track occupancy conflicts, thereby maximizing station operational capacity. However, the existing CTC system still relies on manual input to maintain track availability information, making it difficult to achieve real-time automatic data updates. This results in information lag and errors, severely restricting the efficiency and reliability of station shunting operations.

[0004] With the continuous expansion of the railway network and the increasing density of train operations, the real-time and accurate information on current trains on the tracks is becoming increasingly important for station staff. Manual maintenance methods are no longer sufficient to meet the demands of high-paced, high-precision train operation.

[0005] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for automatically acquiring track current vehicle information in a centralized dispatching system. This method and system can automatically acquire, efficiently transmit, and intelligently apply track current vehicle information. Through technical means, it can achieve dynamic collection and real-time updating of track current vehicles, significantly improve the efficiency of station shunting operations, enhance the safety of transportation organization, and provide key support for the intelligent and automated development of railway operations.

[0007] To achieve the above objectives, this invention provides a method for automatically acquiring current vehicle information on stock tracks, implemented based on a centralized scheduling system, comprising: The track availability interface server in the centralized dispatch system receives track availability information sent from the dispatch information system; The stock trading platform's vehicle information interface server filters the received stock trading platform vehicle information to exclude illegal information; The stock lane vehicle interface server stores the filtered stock lane vehicle information into the database of the centralized dispatch system and notifies the stock lane vehicle management backend server in the centralized dispatch system. According to the notification message from the in-stock train management backend server of the track, the latest in-stock train information is read from the database and sent to the in-stock train management terminal in the dispatching centralized system; After receiving the in-stock train information, the in-stock train management terminal displays the train information on each track in real time.

[0008] The in-stock train information is transmitted between the in-stock train interface server and the dispatching information system through the message queue MQ based on TCP / IP.

[0009] After receiving the in-stock train information, the in-stock train interface server determines the station according to the station code and TMIS code in the in-stock train information. If it is determined to be an illegal station, the in-stock train information of this illegal station is determined as illegal information and discarded.

[0010] The method for judging whether it is an illegal station includes: the in-stock train interface server converts the TMIS code in the in-stock train information sent by the dispatching information system into a legal station number of the dispatching centralized system by querying the station number comparison set. If the TMIS code cannot be converted into a legal station number of the dispatching centralized system, it is an illegal station.

[0011] The method for the in-stock train interface server to store the in-stock train information in the database includes: The in-stock train interface server adds a new in-stock train table structure in the database; The in-stock train interface server determines the unique station through the station code and TMIS code in the in-stock train information, and then locates the specific track through the track code in the in-stock train information; The in-stock train interface server stores the in-stock train information into the in-stock train table structure in the database by stratifying according to the station and the track.

[0012] The first level of the in-stock train table structure is the station, and the second level is the track. The in-stock train table structure contains multiple stations, and each station contains multiple tracks.

[0013] When the in-stock train interface server receives the in-stock train information of the same station again, after updating the existing in-stock train data of this station in the database, it notifies the in-stock train management backend server again that the latest in-stock train information has been received.

[0014] The present invention also provides an in-stock train information automatic acquisition system, including: an in-stock train interface server, an in-stock train management backend server, a database, and an in-stock train management terminal; The track vehicle interface server receives track vehicle information sent from the dispatch information system, filters the received track vehicle information to exclude illegal information, stores the filtered track vehicle information in the database, and notifies the track vehicle management backend server. The stock lane vehicle management backend server reads the latest stock lane vehicle information from the database and sends it to the vehicle management terminal based on the notification message from the stock lane vehicle interface server. After receiving the information on the available trains on each track, the train management terminal displays the train information on each track in real time.

[0015] The stock lane vehicle interface server and the scheduling information system transmit stock lane vehicle information through a TCP / IP-based message queue (MQ).

[0016] After receiving the track current vehicle information, the track current vehicle interface server determines the station based on the station name abbreviation and TMIS code in the track current vehicle information. If it is determined to be an illegal station, the track current vehicle information of the illegal station is judged as illegal information and discarded.

[0017] The track current vehicle interface server converts the TMIS code in the track current vehicle information sent by the dispatch information system into a valid station number in the dispatch centralized system by querying the station number comparison set. If the TMIS code cannot be converted into a valid station number in the dispatch centralized system, it is an illegal station.

[0018] The stock lane vehicle interface server stores the filtered stock lane vehicle information into the database, including: The current vehicle interface server for the stock lane adds a new current vehicle table structure to the database. The track current vehicle interface server determines a unique station by using the station name abbreviation and TMIS code in the track current vehicle information, and then locates the specific track by using the track code in the track current vehicle information. The track availability interface server stores track availability information into the track availability table structure in the database according to the station and track.

[0019] The first level of the track current train schedule structure is the station, and the second level is the track. The track current train schedule structure contains multiple stations, and each station contains multiple tracks.

[0020] When the track availability interface server receives track availability information from the same station again, it updates the existing track availability data for that station in the database and then notifies the track availability management backend server that it has received the latest track availability information.

[0021] The present invention also provides a centralized scheduling system, which includes the aforementioned automatic acquisition system for track vehicle information.

[0022] The present invention has the following beneficial effects: 1. A method and device for obtaining and using CTC track current train information were designed, which opened up the data transmission path for track current train information and enabled the CTC system station to automatically obtain track current train information.

[0023] 2. A transmission protocol for track current vehicle information was designed, dividing the data by station and track, with clear hierarchy and data clarity, providing dispatchers with a clear way to view key information.

[0024] 3. The current vehicle management terminal displays the received track current vehicle information. Compared with the method of manually entering track current vehicles, it reduces the manual input work of station dispatchers, duty officers and other positions, reduces the workload and error risk, and thus improves the efficiency of station transportation operations.

[0025] 4. The data and information enable the automatic acquisition, display, and use of track vehicle information management, effectively reducing the risk of missing important operations during dispatching and command. Attached Figure Description

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the embodiments of the present invention. Please refer to the drawings to make the objectives, features, and advantages of the present invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by the present invention, should still fall within the scope of the technical content disclosed in the present invention.

[0030] like Figure 1 As shown, this invention provides a method for automatically obtaining current vehicle information on stock tracks. This method is based on a centralized scheduling system and specifically includes the following steps: Step 1: The track spot vehicle interface server in the centralized scheduling system receives track spot vehicle information sent from the scheduling information system; The centralized scheduling system and the scheduling information system communicate via a TCP / IP-based message queue (MQ). In this embodiment, an additional message queue (MQ) is added to transmit track current vehicle information. The track current vehicle information includes at least the following key data fields: station name abbreviation (a short code consisting of letters and / or numbers to represent a specific station), TMIS code (a globally unique digital identifier assigned to every station in the country by the railway transport management information system), track code, car number, car type, car type abbreviation, car type category, fuel type, tare weight, length change, vehicle owner, load, arrival telegram code, arrival station name, arrival bureau, direction number, commodity name, consignee, departure telegram code, departure station name, tarpaulin, freight bill abbreviation notes, manual notes, group markings, consignor, and other key information. Step 2: The stock trading platform interface server filters the received stock trading platform information to exclude illegal information; After receiving the track spot information, the track spot interface server determines the station based on the station name abbreviation and TMIS code, and checks whether it is an illegal station. If it is confirmed to be an illegal station, the track spot information of the illegal station is discarded; otherwise, the next step is performed. The method for determining whether a station is illegal includes: if the station numbers in the centralized dispatching system and the dispatching information system are different, the track current vehicle interface server queries the station number comparison set (which is stored in the track current vehicle interface server) to convert the TMIS code sent by the dispatching information system into a valid station number in the centralized dispatching system. If the TMIS code cannot be converted into a valid station number in the centralized dispatching system, then it is an illegal station. Step 3: The stock lane vehicle interface server stores the filtered stock lane vehicle information into the database of the centralized scheduling system and notifies the stock lane vehicle management backend server in the centralized scheduling system. A new track current vehicle table structure is added to the database. The track current vehicle interface server determines a unique station through the station name abbreviation and TMIS code, and then locates the specific track through the track code. After the track current vehicle interface server stores the track current vehicle information into the track current vehicle table structure in the database according to the station and track, it notifies the track current vehicle management backend server in the dispatching centralized system that it has received the latest track current vehicle information. like Figure 2As shown, the first level of the track current vehicle table structure is the station, and the second level is the track. The track current vehicle table structure contains multiple stations, and each station contains multiple tracks. The track current vehicle information is stored in layers according to station and track. The track current vehicle information is organized hierarchically through the track current vehicle table structure to form a track current vehicle data set with a clear structure and easy parsing. When the track spot interface server receives track spot information from the same station again, it updates the existing track spot data for that station in the database and then notifies the track spot management backend server that it has received the latest track spot information. Step 4: The stock lane vehicle management backend server reads the latest stock lane vehicle information from the database and sends it to the vehicle management terminal in the dispatching centralized system based on the notification message from the stock lane vehicle interface server. No need for CTC system dispatchers or duty officers to manually enter track current vehicle information; Step 5: After receiving the track information, the track management terminal displays the train information for each track for station dispatchers, duty officers, and other personnel to view and use, and to arrange station transportation operations.

[0031] like Figure 3 As shown, the present invention provides an automatic acquisition system for stock lane vehicle information. The system is based on a centralized scheduling system 1. The automatic acquisition system for stock lane vehicle information specifically includes: a stock lane vehicle interface server 101, a stock lane vehicle management backend server 102, a database 103, and a vehicle management terminal 104.

[0032] The stock lane vehicle interface server 101 communicates with the scheduling information system 2 through a TCP / IP-based message queue (MQ) to receive stock lane vehicle information sent by the scheduling information system 2 and filter the received stock lane vehicle information to exclude illegal information.

[0033] The track current vehicle interface server 101 transmits the track current vehicle communication message to the CTC system and stores the track current vehicle information 103 into the database 103 of the CTC system according to the station and track hierarchy.

[0034] The track vehicle management backend server 102 reads the latest track vehicle information from the database 103 and sends it to the vehicle management terminal 104 in the dispatching centralized system according to the notification message from the track vehicle interface server 101.

[0035] The database 103 uses a track current vehicle table structure to store track current vehicle information, providing a basis for subsequent data queries.

[0036] The vehicle availability management terminal 104 is mainly responsible for querying the available vehicles on the tracks, automatically acquiring and displaying track availability information, realizing automatic tracking of vehicles between tracks, rationally allocating and utilizing limited track resources, effectively avoiding track occupation conflicts, and thus maximizing station operational capacity. The vehicle availability management terminal 104 displays the latest data in real time based on the track availability data sent by the track availability management backend server 102.

[0037] This invention can automatically acquire, efficiently transmit, and intelligently apply track current vehicle information. Through technical means, it realizes dynamic collection and real-time updating of track current vehicles, significantly improving the efficiency of station shunting operations, enhancing the safety of transportation organization, and providing key support for the intelligent and automated development of railway operations.
