Description

Technical Field

[0001] This application relates to the field of locomotive operation control technology, and in particular to a method, device, equipment and medium for determining locomotive branch line routes. Background Technology

[0002] In the railway transportation system, the safe and efficient operation of locomotives is a key factor in ensuring the smooth operation of the entire transportation network. With the continuous development of railway transportation services, the scale of stations is expanding and the layout of lines is becoming increasingly complex. The operation and management of locomotives within the stations face many challenges, among which the accurate determination of locomotive branch line routes is particularly important.

[0003] Currently, the locomotive operation monitoring equipment requires the crew to manually input the branch line number into the train operation monitoring device when selecting the locomotive's route based on different locomotive operating paths. The train operation monitoring device then retrieves its built-in corresponding line data based on this line number and participates in traction calculations to control the train's operation monitoring equipment to retrieve the correct line data. As the locomotive's branch line number is one of the important train control parameters, the existing method of manual transmission and input poses a safety hazard, such as potential misoperation by the locomotive driver.

[0004] Therefore, how to accurately determine the current location of locomotives and precisely plan branch line routes by utilizing locomotive operation monitoring information and station map information has become an urgent problem to be solved. Summary of the Invention

[0005] In view of this, embodiments of this application provide a locomotive branch line route determination method, apparatus, equipment and medium to solve the problem of how to accurately determine the current position of a locomotive and precisely plan the branch line route using locomotive operation monitoring information and station map information.

[0006] In a first aspect, embodiments of this application provide a method for determining a locomotive branch line route, including:

[0007] The locomotive's operation monitoring information and the station map information of the station are obtained. The positions of preset reference objects in the station map information are extracted. The current position of the locomotive is determined based on the operation monitoring information and the positions of the reference objects.

[0008] Extract the position information of any turnout from the station map information, and determine the locomotive route information passing through any turnout based on the current position and the position information.

[0009] Upon receiving a driving instruction for a target branch line number from the terminal, the locomotive route information of all the turnouts is matched according to the target branch line number to obtain the route driving information for the target branch line number.

[0010] Secondly, according to an embodiment of this application, a locomotive branch line route determination device includes:

[0011] The current location determination module is used to acquire the locomotive's operation monitoring information and the station map information of the station, extract the preset reference points from the station map information, and determine the current location of the locomotive based on the operation monitoring information and the reference points.

[0012] The locomotive information determination module is used to extract the position information of any turnout in the station map information, and determine the locomotive route information passing through any turnout based on the current position and the position information.

[0013] The matching module is used to match the locomotive route information of all the switches according to the target branch line number when it receives the driving instruction of the target branch line number sent by the terminal, so as to obtain the route driving information of the target branch line number.

[0014] Thirdly, embodiments of this application provide a computer device, the computer device including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, it implements the locomotive branch line route determination method as described in the first aspect.

[0016] The beneficial effects of the embodiments in this application compared with the prior art are:

[0017] This application acquires locomotive operation monitoring information and station map information of the station, extracts preset reference point positions from the station map information, determines the locomotive's current position based on the operation monitoring information and the reference point positions, extracts the position information of any turnout from the station map information, and determines the locomotive route information passing through any turnout based on the current position and the position information. When a travel instruction for a target branch line number is received from the terminal, the locomotive route information of all turnouts is matched based on the target branch line number to obtain the route travel information for the target branch line number. By acquiring locomotive operation monitoring information and the station map information of the station, extracting preset reference point positions from the station map and combining them with the operation monitoring information to determine the locomotive's current position, extracting turnout position information from the station map and combining it with the current position to determine the locomotive's route information passing through the turnouts, and finally matching the route information of all turnouts when a travel instruction for the target branch line number is received from the terminal, the route travel information for the target branch line number is obtained.

The server is used to control the locomotive branch line route determination method sent by the client.

[0035] The client side includes, but is not limited to, PDAs, desktop computers, laptops, ultra-mobile personal computers (UMPCs), netbooks, cloud terminal devices, and personal digital assistants (PDAs). The server side can be a standalone server or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms.

[0036] See Figure 2 This is a flowchart illustrating a locomotive branch line route determination method provided in Embodiment 2 of this application. The above-described locomotive branch line route determination method can be applied to... Figure 1 The server-side component.

[0037] like Figure 2 As shown, the method for determining the branch line route of the locomotive may include the following steps:

[0038] Step S201: Obtain the locomotive's operation monitoring information and the station map information of the station where it is located, extract the preset reference points from the station map information, and determine the current position of the locomotive based on the operation monitoring information and the reference points.

[0039] Optionally, after obtaining the locomotive's operation monitoring information and the station's layout map information, the following steps may also be included:

[0040] The station map information collected by the acquisition device is obtained in real time, and the station map information is updated according to the real time information to obtain updated information;

[0041] The updated information is stored to obtain a storage information database, and the preset reference positions in the storage information database are extracted.

[0042] Optionally, the step of extracting the preset reference point positions from the station map information and determining the current position of the locomotive based on the operation monitoring information and the reference point positions may further include the following steps:

[0043] Extract the signal positions from the station map information, and determine the relative distance between the locomotive and the signal positions based on the operation monitoring information;

[0044] The current position of the locomotive is determined based on the relative distance.

[0045] Among these, operational monitoring information consists of dynamic data about the locomotive's operating status, such as its speed, direction of travel, and mileage. This information is typically collected through various sensors installed on the locomotive; for example, speed sensors measure the locomotive's real-time speed, and direction sensors determine its direction of travel.

[0046] The station layout map is a static diagram of the station, containing the location information of various facilities within the station, such as the track alignment, the location of switches, and the distribution of signals. The station layout map can be a pre-drawn electronic map stored in the system for subsequent analysis.

[0047] The station layout plan contains pre-defined reference points, which are objects with fixed locations within the station, such as specific buildings and track markers. Extracting the positions of these reference points provides reference points for determining the locomotive's location.

[0048] By combining operational monitoring information and the positions of reference points, the current position of the locomotive can be determined. For example, given the locomotive's direction and speed, and the position of a reference point, the distance the locomotive has traveled from a known starting point to the current moment can be calculated. Combined with the position of the reference point, the locomotive's position relative to the reference point can be determined, thus pinpointing the locomotive's exact location within the station.

[0049] Real-time information from the station site map is collected using various data acquisition devices (such as cameras and track sensors). These devices can monitor the actual conditions of the station site in real time, such as whether there is temporary construction or obstacles on the tracks. Based on the collected real-time information, the original station site map information is updated. If there is temporary construction in the station site, the real-time information will reflect the location of the construction area. By updating the station site map information, the construction area is marked, ensuring that the station site map information is consistent with the actual situation. The updated information is stored to form a database. This facilitates subsequent queries and use, while also ensuring that the system always uses the latest station site information. Preset reference point locations are extracted from the database. Since the station site map information has been updated, the locations of reference points may need to be redefined due to changes (such as the construction of new buildings).

[0050] Locate the signal positions from the station map information. Signals are crucial traffic control devices in the station, and their positions are fixed and known. Based on locomotive operation monitoring information, calculate the relative distance between the locomotive and the signal positions. For example, by combining the locomotive's speed and travel time with the signal's position, the distance between the locomotive and a given signal can be calculated. Based on the relative distance, further determine the locomotive's current position. For instance, knowing the distance of the locomotive to a signal ahead, and combining this with the signal's position on the station map, the locomotive's exact position can be determined.

[0051] Step S202: Extract the position information of any turnout in the station map information, and determine the locomotive route information passing through any turnout based on the current position and the position information.

[0052] Optionally, the step of extracting the position information of any turnout in the station map information, and determining the locomotive route information passing through any turnout based on the current position and the position information, may include the following steps:

[0053] Extract the association information between the turnout and the station layout information;

[0054] Based on the associated information, the position information of the turnout is determined, and based on the current position and the position information, the locomotive route information passing through any turnout is determined.

[0055] The station layout map contains detailed information about the station, with turnouts being key facilities for changing the direction of train travel. Extracting the location information of any turnout from the station layout map is the basis for determining the locomotive route. The turnout's location information accurately indicates its specific location within the station's track network, usually expressed as coordinates or its relative position to other fixed landmarks (such as signals, specific track nodes, etc.).

[0056] In step S201, the current position of the locomotive has been determined. By combining this current position with the position information of the turnout, the possible travel path of the locomotive when passing through the turnout can be analyzed, i.e., the locomotive route information. For example, if the locomotive is currently located on one side of the turnout, based on the locomotive's travel direction and the different opening states of the turnout (straight track or curved track), it can be determined which track the locomotive will travel on after passing through the turnout.

[0057] Turnouts do not exist in isolation within a station yard; they are closely interconnected with surrounding tracks, signals, and other facilities. The station yard map records this interconnected information. By extracting the information related to turnouts, a more comprehensive understanding of their role and impact within the entire station yard system can be achieved. This interconnected information may include which tracks the turnout is directly connected to, which signals control the turnout, and the interlocking relationships between the turnout and adjacent turnouts.

[0058] Correlation information can help determine the location of a turnout more accurately. Sometimes, relying solely on the turnout's coordinates may not be accurate enough or easy to understand. However, by understanding its relationship with surrounding facilities, the turnout's location can be clarified from a more macroscopic and specific perspective. For example, knowing the distance and relative direction of a turnout to a certain signal, as well as the exact location of that signal, allows for more precise turnout location.

[0059] By combining the locomotive's current position with the switch position determined through associated information, the locomotive's route information through that switch can be determined more accurately and comprehensively. Taking into account the switch's associated information allows for a better analysis of various situations the locomotive might encounter when passing through a switch, such as signal displays and the status of adjacent switches, thus enabling the development of the most reasonable and safest route plan. For example, if a switch is controlled by a specific signal, the signal's display status can determine whether the locomotive can pass through the switch and its direction of travel after passing through.

[0060] Step S203: Upon receiving the driving instruction for the target branch line number sent by the terminal, the locomotive route information of all the switches is matched according to the target branch line number to obtain the route driving information of the target branch line number.

[0061] The terminal can be a control terminal in the dispatching room, an operating terminal for the locomotive driver, etc. Based on the transportation plan and station operation arrangements, dispatchers issue instructions via the terminal for the locomotive to proceed to a specific target branch line. This instruction is presented as a target branch line number. The target branch line number clearly identifies the specific branch line track the locomotive ultimately needs to reach; it represents the locomotive's destination for this journey, and subsequent route matching and planning revolve around this target.

[0062] In step S202, the route information for the locomotive passing through any turnout in the station yard has been determined. This information includes the possible travel direction when passing each turnout, the subsequent connecting tracks, etc. The target branch line number is compared with the route information of all turnouts. The track network in the station yard consists of multiple turnouts and branch lines. There may be multiple different travel paths from the locomotive's current position to the target branch line. It is necessary to analyze whether the route of each turnout can lead to the target branch line. For example, some turnout routes may lead to other branch lines or main tracks, which do not meet the requirements of the target branch line and will be excluded; while those routes that can connect to the target branch line are retained for further analysis.

[0063] After matching and filtering all turnout route information, a series of continuous routes that can guide the locomotive from its current position to the target branch line are finally determined. This route information is integrated to form the route travel information for the target branch line number, which details the locomotive's specific route in the station yard, including the turnouts it needs to pass through and the direction of travel at each turnout. The route travel information provides clear operational guidance for the locomotive driver and also provides control basis for the station's signal control system, ensuring that the locomotive can safely and accurately travel to the designated target branch line.

[0064] This application acquires locomotive operation monitoring information and station map information of the station, extracts preset reference point positions from the station map information, determines the locomotive's current position based on the operation monitoring information and the reference point positions, extracts the position information of any turnout from the station map information, and determines the locomotive route information passing through any turnout based on the current position and the position information. When a travel instruction for a target branch line number is received from the terminal, the locomotive route information of all turnouts is matched based on the target branch line number to obtain the route travel information for the target branch line number. By acquiring locomotive operation monitoring information and the station map information of the station, extracting preset reference point positions from the station map and combining them with the operation monitoring information to determine the locomotive's current position, extracting turnout position information from the station map and combining it with the current position to determine the locomotive's route information passing through the turnouts, and finally matching the route information of all turnouts when a travel instruction for the target branch line number is received from the terminal, the route travel information for the target branch line number is obtained. Thus, by utilizing locomotive operation monitoring information and station map information, the current position of the locomotive can be accurately determined, and the branch line route can be precisely planned.

[0065] See Figure 3 This is a flowchart illustrating a method for determining a locomotive branch line route according to Embodiment 3 of this application. Figure 3 As shown, step S202, which involves determining the locomotive route information passing through any turnout based on the current position and the position information, may include the following steps:

[0066] Step S301: Determine the locomotive's direction of travel at any of the switches based on the location information;

[0067] Step S302: Obtain the preset destination position, and determine the route for the locomotive to reach the destination position based on the current position and the direction of travel.

[0068] Step S303: Determine the locomotive route information that passes through any turnout based on the described path.

[0069] The location information includes the locomotive's current position and the specific location of the turnout on the station map. Turnouts in the station serve to change the direction of the tracks, typically having different states such as turning on the straight track or the curved track.

[0070] Based on the locomotive's current position and the location and status of the turnout, determine the appropriate direction of travel when the locomotive reaches the turnout. For example, if the locomotive is currently approaching a turnout, depending on the turnout's layout and the locomotive's direction of travel, if continuing forward would meet subsequent operational or traffic requirements, the locomotive might choose to travel straight at the turnout; if turning would reach the destination faster or if a turn is required according to a predetermined plan, the locomotive would choose to travel on the curved track.

[0071] The preset destination is a pre-defined location, which may be the locomotive's destination for this operation, such as a cargo loading / unloading point or a vehicle marshalling yard.

[0072] Given the locomotive's current position and direction of travel at each switch, a route from the current position to the predetermined destination is planned. The station's track network consists of multiple switches and connected tracks, and the locomotive needs to pass through multiple switches to reach its destination. Therefore, the system comprehensively considers the direction of travel at each switch and uses an algorithm (such as a path planning algorithm) to find a path that allows the locomotive to successfully reach its destination. This path clearly indicates which switches and track sections the locomotive needs to pass through in sequence.

[0073] Once the route is determined, the relevant information about each turnout the locomotive passes through during its entire journey can be clearly defined. For each turnout, the route information includes which track the locomotive enters from, the direction of travel chosen at the turnout (straight or curved), and which track it will enter after exiting the turnout. This information comprehensively describes the locomotive's specific travel situation when passing each turnout, providing detailed guidance for the safe operation of the locomotive in the station yard.

[0074] See Figure 4 This is a flowchart illustrating a method for determining a locomotive branch line route according to Embodiment 4 of this application. Figure 4 As shown, step S203, which involves matching the locomotive route information of all the turnouts according to the target branch line number to obtain the route travel information of the target branch line number, may include the following steps:

[0075] Step S401: Based on the target branch line number, filter the locomotive route information to obtain the branch line path corresponding to the target branch line number and the control information corresponding to the branch line path;

[0076] Step S402: Determine the route information of the target branch number based on the branch path and the control information.

[0077] The target branch line number specifies the particular branch line track the locomotive will eventually reach. The previous steps have already determined the locomotive's route information through each switch, which includes various possible paths the locomotive might take within the station yard.

[0078] The system compares the target branch line number with all locomotive route information, filtering out paths that lead to the target branch line from among numerous route options. These paths are the branch line paths corresponding to the target branch line number. The control information for the branch line path includes instructions and parameters to ensure the locomotive can travel safely and accurately along that path. This control information may include the opening direction of switches (because different opening directions determine the locomotive's direction of travel), the display status of signals (such as red lights, green lights, etc., indicating whether the locomotive can proceed), and track speed limits. For example, if a branch line path passes through a switch, the control information will specify whether the switch should be on the straight or curved track; if there is a signal on the path, it will provide the correct signal display status.

[0079] The branch line path describes the sequence of tracks and switches that the locomotive must traverse from its current position to the target branch line, while the control information specifies the operational requirements for each key node (such as switches and signals) during the locomotive's journey. Combining these two elements forms complete route information.

[0080] The route information details how the locomotive should travel at each switch (choosing between straight and curved tracks), the rules to follow when encountering signals (whether to stop, accelerate, etc.), and the speed requirements on each track segment. For example, the route information might instruct the locomotive to first pass switch A, choosing to travel on the straight track. At this point, the switch should be open for straight tracks, and the corresponding signal should display a green light indicating passage is permitted. After traversing a section of track, upon reaching switch B, the locomotive should choose to travel on the curved track. Switch B should be pre-set to the curved track open state, and so on.

[0081] In this embodiment of the application, by filtering out the branch path and control information corresponding to the target branch number, and then determining the final route travel information based on this information, an accurate and executable travel route is planned for the locomotive.

[0082] See Figure 5 This is a flowchart illustrating a locomotive branch line route determination method provided in Embodiment 5 of this application. Figure 5 As shown, after obtaining the route information for the target branch number, step S203 may further include the following steps:

[0083] Step S501: Set control commands for each turnout based on the route travel information.

[0084] Step S502: Determine the locomotive's route mode according to the control command.

[0085] The route information details the locomotive's journey from its current position to the target branch line, including which switches it passes through and the direction of travel (straight or curved) at each switch. Based on this route information, corresponding control commands are set for each switch. The main function of these control commands is to ensure that the switches are in the correct open state to meet the locomotive's travel needs. For example, if the route information indicates that the locomotive needs to choose the straight track when passing switch A, the control command will instruct switch A to open the straight track; if the locomotive needs to turn at switch B, the control command will instruct switch B to open the curved track. The control commands may also involve locking and unlocking switches to ensure that the switches do not change unexpectedly when the locomotive passes.

[0086] The route mode refers to the specific pattern and rules by which locomotives travel along planned routes within the station yard. It comprehensively considers factors such as the control status of switches, signal displays, and locomotive speed. Based on the control commands for each switch, combined with the station's signaling system and safety regulations, the locomotive's route mode is determined. For example, if the control command for a switch is to open the straight track and the signal shows a green light, the locomotive can pass through the switch at normal speed; if the switch is in transition or the signal shows a red light, the locomotive must stop and wait. The route mode may also include different speed requirements, such as slowing down when approaching a switch and accelerating again after passing it. By rationally determining the route mode, the safe and efficient operation of locomotives within the station yard can be ensured.

[0087] In this embodiment of the application, the locomotive's route is determined by control commands, thereby ensuring that the locomotive can safely and accurately reach the target branch line according to the planned route.
