Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit, and in particular relates to a CTC shunting plan control method and system. Background Art

[0002] The existing railway shunting operations involve computer interlocking systems, CTC (dispatching centralized control system), routes, train operations, shunting operations, shunting routes, and storage shunting, etc. Among them, the computer interlocking system is referred to as interlocking, which is responsible for controlling the signal equipment in the station, including turnouts, sections, signal machines, and the safety interlocking relationship between turnouts, signal machines, and track circuits in the constrained routes. It accepts the control instructions of the operator, controls outdoor railway signal equipment such as turnouts, sections, and signal machines, and provides real-time feedback on the status of signal equipment. The jurisdiction of a set of interlocking is a station. CTC is widely used in the field of railway dispatching command and signal control. It is an important equipment for railway transportation management, realizing the informatization of dispatching command, automation of train operations, and centralization of signal equipment. CTC centralizes signal systems and information systems such as interlocking systems, train control systems, and speed limit systems, and connects stations and sections in series to form a complete line display map for use by dispatchers and train personnel. It is the eyes and hands of dispatchers. Dispatchers can see each signal equipment at each station, the location information of each train, plan information, etc. through the CTC system, and can remotely control signal equipment and train operation paths and speeds. The route refers to the path that trains and shunting locomotives take from one location to another in the station. Route handling (or route triggering) means that before the locomotive enters this route, the signal equipment passing through the route needs to be locked and the permission signal is opened. The locomotive can enter the route only after seeing the permission signal. After the locomotive passes, the equipment returns to the clearing state (unlocked state, unoccupied state). The route includes train routes and shunting routes, among which the train routes include three types: receiving routes, departure routes and passing routes. Trains are groups of vehicles (a carriage) plus a locomotive (head) for cross-station operation, which can be roughly divided into passenger cars and freight cars. Train operations refer to the connection of trains to the station, departure from the station, passing through the station, and some inspections, passenger boarding and alighting, etc. in the station. Signal control mainly involves the handling of receiving routes, departure routes, and passing routes. Which trains are received and dispatched at each station every day is determined by the dispatcher of the corresponding line on the CTC system operation diagram. The original route handling is completed on the interlocking system, and it is necessary to manually click the start, end, and change point buttons to handle the route handling, which is prone to errors and has no more safety card control. Shunting operations refer to the movement of vehicles or locomotives within the station, including organizing multiple vehicles together to form a train, disassembling the vehicles of the train and allocating them to various tracks, arranging locomotives for trains, changing locomotives, and other operation scenarios. Each moving action is called a hook operation, so the shunting plan is also called a "hook plan" or "hook". The station dispatcher prepares a shunting operation plan based on the daily operation plan. Each shunting operation plan contains several hooks, and the operators in the relevant positions print out a paper shunting operation plan.The outdoor shunting driver contacts the station signalman by phone to request the shunting route of the designated hook. The signalman determines the route based on the outdoor verbal description and manually presses the start and end signal buttons to handle the shunting route. This process is highly dependent on people, and accuracy and safety cannot be guaranteed. In this working mode, the shunting operation sheet and the route are not associated, and the outdoor operation driver's main road and the route handling are not associated. These two disconnections are made up manually, and manual participation increases the risk of errors. Railway shunting operations are divided into locomotive push mode and shunting mode according to the operation mode. Shunting shunting operations can be divided into hump shunting and plane shunting. Hump shunting is realized by the hump system, and plane shunting is controlled by the interlocking system. Storage shunting refers to compiling multiple shunting hook plans into a form in advance, which are executed sequentially by the interlocking system.

[0003] Furthermore, CTC provides shunting plan management and route signal control, which is currently only applied to shunting operations under locomotive push mode. Shunting operations use vehicle inertia to achieve vehicle movement, and the locomotive does not need to follow the vehicle. Among them, shunting can be divided into hump shunting and flat shunting. Since there is no interface specification between CTC and the hump system, the existing interface specification does not specify the control commands related to shunting and the protocol for storing shunting plans, and hump shunting control has not been realized. For some stations with flat shunting operations, the shunting route is controlled by the interlocking system. Because the existing CTC and interlocking interface content does not include flat shunting route control, that is, the stations currently involved in shunting are all controlled by the interlocking system, resulting in these stations can only use the original interlocking system control signal, and cannot realize CTC dispatching centralized control. Train personnel cannot use CTC to prevent wrong route, automatically trigger route, operation process control and other functions to improve the efficiency and safety of train shunting operations.

[0004] How to control plane sliding operation through CTC is becoming an increasingly urgent technical problem to be solved. Summary of the invention

[0005] In view of the above problems, the present invention provides a CTC shunting plan control method and system, which improves the efficiency and safety of train shunting operations.

[0006] The object of the present invention is to provide a CTC shunting plan control method, comprising: Prepare shunting plan based on configuring shunting area and marking shunting hook plan; Based on the hook release plan in the compiled shunting plan, a shunting route sequence is generated, where the shunting route meets the following requirements: when the locomotive moves into the track, the route equipment is not unlocked, and when the locomotive returns, the route signal is automatically opened; Trigger the slipping route and process the slipping route to the destination section at one time. It is not allowed to process it in sections according to the short route.

[0007] Further, configuring the sliding area includes, Configure the name of the release point section and the name of the release destination track; Determine the shunting area based on the configured shunting point section name and the shunting destination track name.

[0008] Furthermore, the compiled shunting plan includes a shunting hook plan and a push hook plan, and the marking shunting hook plan includes: Add markers for starting and ending the sled in the sled hook plan.

[0009] Furthermore, each hook release plan corresponds to a unique release route, wherein the starting end and the end end of the release route are fixed.

[0010] Further, based on the shunting hook plan in the compiled shunting plan, generating the shunting route sequence also includes if the previous shunting hook plan of the shunting hook plan is a push hook plan, Generate the pull-out route from the working track to the release point based on the push hook plan; Based on the hook release plan, generate the pulling route from the release point to the working track.

[0011] Further, based on the shunting hook plan in the compiled shunting plan, generating the shunting route sequence also includes if the next shunting hook plan of the shunting hook plan is a push hook plan, Based on the hook release plan, generate the release route from the release point to the operating track and the pull-out route from the operating track to the turnaround point; Based on the push hook plan, the pull-in route and pull-out route in the push route sequence are generated.

[0012] Furthermore, based on the shunting hook plan in the compiled shunting plan, generating the shunting route sequence also includes performing a shunting route preview based on the shunting signal, wherein: All shunting signals in both directions of the shunting approach are flashing bright white, and the approach is locked.

[0013] Furthermore, triggering the release route also includes: When the sliding route is processed for the first time, the start button is the sliding starting point button; When handling the subsequent shunting route in the shunting plan, if the locomotive turns back halfway and is pulled into the next shunting hook track, the starting end of the route will calculate the short route that needs to be triggered based on the position occupied by the locomotive, and combine the short routes into a long route to trigger the shunting route at one time.

[0014] Further, triggering the slipping route also includes checking whether the slipping function at the starting end of the slipping route is turned on according to the state of the slipping indication light when the slipping route is triggered, and if not, performing card control.

[0015] Another object of the present invention is to provide a CTC shunting plan control system, comprising: The compilation module is used to compile the shunting plan based on the configured shunting area and marked shunting hook plan. A generation module is used to generate a shunting route sequence based on the shunting hook plan in the compiled shunting plan, wherein the shunting route satisfies: when the locomotive moves into the track, the route equipment is not unlocked, and when the locomotive returns, the route signal is automatically opened; The trigger module is used to trigger the slipping route and process the slipping route to the destination section at one time. It is not allowed to process it in sections according to the short route.

[0016] The CTC shunting plan control method of the present invention controls the shunting route so that the route equipment is not unlocked when the locomotive moves in. When the locomotive returns, it directly returns from the original route of the shunting route, and the shunting route is processed once when the route is triggered, eliminating the return route processing link, thereby improving the safety and efficiency of shunting operations. Furthermore, the control method enables stations with flat shunting operations to switch to CTC control mode, allowing train operators to adjust and control shunting signals through CTC and realize the storage shunting function, relying on CTC to improve the efficiency and safety of train shunting operations.

[0017] Furthermore, a mixed approach is adopted to integrate the shunting plan of the shunting method with the existing push method shunting plan, so as to realize the adaptive generation of route sequences and triggering routes of the two plans.

[0018] In addition, marking the hook release plan ensures the accuracy of the input, facilitates subsequent logical calculations, and improves the safety and reliability of the shunting plan.

[0019] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures pointed out in the description, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0021] Figure 1 A schematic diagram of a CTC shunting plan control method in an embodiment of the present invention is shown; Figure 2 A schematic diagram of another CTC shunting plan control method process in an embodiment of the present invention is shown; Figure 3 A schematic diagram of the structure of a CTC shunting plan control system in an embodiment of the present invention is shown. DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, a CTC shunting plan control method is introduced in an embodiment of the present invention, and the control method includes, first, compiling a shunting plan based on configuring a shunting area and marking a shunting hook plan, and then, generating a shunting route sequence based on the shunting hook plan in the compiled shunting shunting plan, wherein the shunting route satisfies: when the locomotive moves into the track and passes, the route equipment is not unlocked, and when the locomotive returns, the route signal is automatically opened; finally, the shunting route is triggered, and the shunting route is processed to the destination section at one time, and it is not allowed to be processed in sections according to the short route. For ordinary push routes, if the locomotive turns back and presses on the turnout midway, a complete route cannot be established at the position of the turnout. It is necessary to manually confirm that the turnout is at the position required by the locomotive, and manually lock the turnouts one by one. At the same time, it is necessary to contact outdoor personnel for confirmation before the locomotive can run. This process is both cumbersome and has safety hazards. Therefore, in the embodiment of the present invention, the shunting route is controlled by CTC, and the route equipment is not unlocked during migration. When the locomotive returns, it directly returns from the original route of the shunting route, eliminating the return route processing link and improving the safety and efficiency of shunting operations.

[0024] like Figure 2 As shown, to convert the station with flat shunting operation to the CTC control mode, first of all, it is necessary to open up the shunting route control of CTC and the interlocking system. Specifically, the CTC shunting plan control system described below is adopted. The CTC shunting plan control system has the ability to uniformly control the shunting plan, that is, it can maintain the existing interface specification protocol format of CTC unchanged without affecting the existing functions, and can also expand the types of instructions related to shunting establishment and shunting cancellation, thereby improving the reliability and safety of shunting plan control.

[0025] Secondly, a shunting plan is prepared, which includes configuring a shunting area and marking a shunting hook plan. Unlike ordinary push shunting, plane shunting is limited to a specified area, so it is necessary to specify the shunting point and the shunting destination track. Then, configuring the shunting area includes, first, configuring the shunting point section name and the shunting destination track name; then, based on the configured shunting point section name and the shunting destination track name, determining the shunting area. In the embodiment of the present invention, multiple shunting areas can be configured. When preparing a shunting hook plan, the operating track is restricted to the shunting area, so that the reliability of preparing the shunting shunting plan can be improved.

[0026] Furthermore, the compiled shunting hook plan includes a shunting hook plan and a push hook plan, and marking the shunting hook plan includes adding start shunting and end shunting marks in the shunting hook plan. Preferably, in order to distinguish between the two hook plans, a note column can be set in the system, and the note column provides quick formatted input options "start shunting" and "end shunting". The hook plan from "start shunting" to "end shunting" is represented as a shunting hook plan, otherwise it is a push hook plan. Using the above method to mark the shunting hook plan is not only convenient for input, but also ensures the accuracy of the input. The input result is directly used as logical data and can participate in subsequent logical calculations, thereby improving the compilation efficiency. However, it is not limited to marks such as "start shunting" and "end shunting", and other marking methods are also applicable to embodiments of the present invention.

[0027] Then, a sliding route sequence is generated, in which each sliding hook plan corresponds to a unique sliding route, in which the starting and ending points of the sliding route are fixed. The sliding route is the basic route from the sliding point of the throat to the working track. It should be noted that the basic route refers to the route processed by the two buttons of the starting section and the terminal section, which is different from the alternative route. The alternative route is a detour route that is different from the basic route path processed by the starting and ending points and several alternative buttons. In addition, after the sliding route sequence is generated, manual changes to the sequence are not allowed. Furthermore, the sliding route satisfies: when the locomotive moves into the track and passes, the route equipment is not unlocked, and when the locomotive returns, the route signal is automatically opened. Preferably, if there is a station with flat shunting, the shunting approach is given priority. The shunting approach is not limited to shunting operations, but can also be used in pushing operations. In this way, the characteristic of the shunting approach that it can be pulled in without unlocking can be utilized, and there is no need to handle the push-out approach. Therefore, the shunting approach is applied to the push-shunting operation mode. By utilizing the characteristics of the flat shunting approach, the shunting hook plan does not need to generate a return pull-out approach sequence from the track to the shunting point. The locomotive returns directly from the shunting approach along the original route, eliminating the return approach handling link and improving the safety and efficiency of shunting operations.

[0028] In an embodiment of the present invention, based on the shunting hook plan in the compiled shunting shunting plan, generating a shunting route sequence also includes if the previous shunting plan of the shunting hook plan is a push hook plan, first, based on the push hook plan, generating a pull-out route from the working track to the shunting point (i.e., generating a push route sequence); then, based on the shunting hook plan, generating a pull-in route from the shunting point to the working track (i.e., the shunting route). Exemplarily, if the shunting hook plan A is after the push hook plan T, the push hook plan T generates a pull-out route from the working track to the shunting point, and the shunting hook plan A generates a pull-in route from the shunting point to the working track. Different from the prior art, in order to connect with the next shunting hook plan, the pull-out point of the push hook plan T defaults to the shunting point, and cannot be selected according to the original push route method.

[0029] In an embodiment of the present invention, based on the sliding hook plan in the compiled sliding shunting plan, generating a sliding route sequence also includes if the next shunting plan of the sliding hook plan is a push hook plan, first, based on the sliding hook plan, generating a sliding route from the sliding point to the working track and a pull-out route from the working track to the turning point; then, based on the push hook plan, generating a pull-in route and a pull-out route in the push route sequence (i.e., generating a push route sequence). Exemplarily, if the sliding hook plan A is before the push hook plan T, the push hook plan T generates a pull-in route and a pull-out route, and the sliding hook plan A generates two routes, one is the sliding route from the sliding point to the working track, and the other is a common pull-out route from the working track to the turning point Z, wherein the turning point Z is the optimal turning point of the two hook plans, the push hook plan T and the sliding hook plan A, according to the existing push route generation sequence. This is because when the next hook is a push hook, the sliding operation has been completed at hook A, that is, the sliding hook plan has been completed. At this time, the sliding route has not been unlocked, and the sliding route needs to be manually canceled, and then the ordinary pull-out route is processed. Among them, since the common turning point of the T operating track and the A operating track does not necessarily include the sliding point, in order to flexibly select the turning point, when executing the next push hook plan, it is necessary to generate the route sequence according to the push hook plan, that is, to generate the pull-out route. Preferably, if Z is the sliding point, the unlocked sliding route can still be used as the pull-out, and the pull-out route generated by the system according to the push hook plan can be directly skipped.

[0030] In an embodiment of the present invention, based on the shunting hook plan in the compiled shunting plan, generating a shunting route sequence also includes previewing the shunting route based on the shunting signal, wherein the shunting signals in both directions of the shunting route all flash bright white, and the route is locked. CTC generates a route sequence according to the shunting plan. Manually, through the route sequence, the execution effect can be quickly previewed in advance and then the route is triggered, which reduces the workload of shunting route handling, and also avoids the risk of manual errors in clicking multiple buttons to handle the route. The accuracy of the compiled shunting plan can be better grasped through the preview.

[0031] Finally, trigger the shunting route. Specifically, when the shunting route is triggered, the shunting route will be processed to the destination section at one time, and it is not allowed to be processed in sections according to the short route. Among them, if this condition is not met, that is, if it cannot be processed to the destination section at one time, the shunting route will not be allowed to be processed, which effectively ensures the safety and reliability of the triggering of the shunting route. Furthermore, triggering the shunting route also includes when the shunting route is processed for the first time, the starting button is the shunting starting point button; when the subsequent shunting routes (routes in other shunting hook plans in the shunting plan) are processed, if the locomotive turns back from the middle and pulls into the next hook (shunting hook plan) track, the starting end of the route (that is, the starting end of the next shunting hook route) calculates the short route that needs to be triggered according to the locomotive's occupied position, and combines the short routes into long routes to trigger the shunting route at one time.

[0032] In addition, triggering the sled route also includes checking whether the sled function at the beginning of the sled route is turned on according to the state of the sled indicator light when the sled route is triggered. If it is not turned on, card control is performed to prevent the normal push route from being processed and affecting efficiency. Due to the interface between the CTC system and the interlocking system, CTC realizes the control and display of signal equipment based on the interlocking system. Therefore, CTC also inherits the safety card control function of the interlocking system, and adds many safety card control and efficiency improvement functions on the basis of the interlocking system. Therefore, card control in the plane sled operation can ensure the safety of the route and improve the reliability of the shunting operation.

[0033] like Figure 3 As shown, an embodiment of the present invention also introduces a CTC shunting plan control system capable of executing the above method, wherein the control system is arranged in the CTC system, and includes a compilation module, a generation module and a trigger module, wherein the compilation module is used to compile a shunting plan based on the configuration of the shunting area and the marking of the shunting hook plan; the generation module is used to generate a shunting route sequence based on the shunting hook plan in the compiled shunting shunting plan, wherein the shunting route satisfies: when the locomotive moves into the track and passes, the route equipment is not unlocked, and when the locomotive returns, the route signal is automatically opened; the trigger module is used to trigger the shunting route, and the shunting route is processed to the destination section at one time, and it is not allowed to be processed in sections according to the short route.

[0034] CTC controls the shunting approach through the shunting plan control system to realize the storage shunting function, so that stations with flat shunting operations can be switched to CTC control mode. In addition, the shunting approach is controlled by the control system, and the approach equipment is not unlocked during migration. When the locomotive returns, it returns directly from the original shunting approach, eliminating the return approach processing link and improving the safety and efficiency of shunting operations.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
