Description

Technical Field

[0001] This invention relates to the field of railway shunting operations, and in particular to a shunting operation control method and system. Background Technology

[0002] Shunting operations are a crucial component of railway transportation production, involving multiple trades such as train operation, locomotive operation, and rolling stock maintenance, and involving various equipment including locomotives, switches, and signals. The operating environment is complex and dynamically changing. Due to the large number of participating factors and the high requirements for coordination, negligence or errors in any link can lead to serious consequences. Therefore, establishing a rigorous and reliable joint control mechanism to achieve seamless information connection and real-time mutual control between various positions and systems is a vital foundation for ensuring the safe and efficient operation of shunting.

[0003] In shunting operations, the joint control system plays a crucial role. This system is rigorous and complex, involving multiple projects and critical timings. By strictly adhering to these projects and timings during joint control operations, the efficiency and safety of shunting operations can be ensured.

[0004] Traditional shunting operation coordination relies primarily on manual methods. Shunting plans are typically transmitted and handed over manually in the form of paper shunting notices. Confirmation of status such as route processing, signal clearance, and vehicle movement depends on inquiries and responses between indoor signalmen and on-site shunting team members via walkie-talkies. The flow of information such as relevant work instructions, route advance notices, and location reports relies on voice communication between operators. This human-centric coordination model suffers from problems such as low information transmission efficiency, susceptibility to errors, insufficient real-time and synchronous capabilities, and a lack of effective process recording and traceability methods.

[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 shunting operation joint control method and system that integrates existing centralized dispatching systems and horizontal shunting systems. This enables station shunting operations to transform from the current manual transmission of shunting operation plans and telephone notification of route processing to automatic plan issuance, automatic voice broadcasting, real-time status feedback, automatic route verification, and full process recording. This achieves automatic command of shunting teams and drivers, improving the efficiency and safety control level of shunting operations. At the same time, it fundamentally reduces human intervention, improves the reliability, real-time performance, and standardization of joint control, and provides technical support for the safety and efficiency of railway shunting operations.

[0007] To achieve the above objectives, the present invention provides a shunting operation joint control method, comprising the following steps: a centralized dispatching system pushes a shunting operation order to at least one handheld terminal through an interface server and a section chief's console; the handheld terminal triggers an operation request signaling based on the shunting operation order, and the operation request signaling is sent to the centralized dispatching system via the section chief's console and the interface server; the centralized dispatching system responds to the operation request signaling by performing corresponding route control or safety status check operations; the centralized dispatching system generates a status feedback instruction based on the result of the route control or safety status check operation, and sends it to the handheld terminal through the interface server and the section chief's console, broadcasting it to the shunting team and / or driver in voice form.

[0008] In one embodiment, the job request signaling includes a first signaling for requesting shunting and a second signaling for requesting reversal.

[0009] In one embodiment, the triggering condition for the first signaling is that the shunting group has completed the connection work within the line, and there is no abnormality at the current work position, thus meeting the basic conditions for processing the route from the current position to the planned next position.

[0010] In one embodiment, the centralized scheduling system responds to the first signaling, and the corresponding route control operation is to process a shunting route, including: processing a shunting route from the current work position to the next planned work position based on the shunting work order.

[0011] In one embodiment, the second signaling is triggered when the shunting group has completed the connection operation within the line, but the number of cars on the planned operation line is insufficient to accommodate the locomotives and cars currently in operation, and it is necessary to retreat and turn back from the middle of the line.

[0012] In one embodiment, the centralized dispatching system responds to the second signaling, and the corresponding safety status check includes: not processing the route, checking the locking status of the switches and / or the route occupancy on the reversal or turnaround path, and feeding back the check results to the interface server; or processing the shunting route for reversal from any location; or confirming that all switches on the reversal path are in the locked state, and replying to the shunting operator via voice to allow the reversal.

[0013] In one embodiment, the first signaling and the second signaling use the same idle signaling code in the wireless transmission layer sent from the handheld terminal to the district station, and are parsed and distinguished by the interface server in conjunction with the operation phase.

[0014] In one embodiment, the shunting operation information on the shunting operation order includes at least one of the following: order number, locomotive number, train number, horizontal shunting number, operation plan start time, operation plan end time, shunting sequence number, track, direction, number of cars, and operation precautions.

[0015] In one embodiment, the step of broadcasting the status feedback instruction to the shunting crew and / or driver in voice form includes the following steps: the centralized dispatching system sends the status feedback instruction to the interface server; the interface server parses the status feedback instruction to generate wireless signaling; the status feedback instruction is converted into corresponding voice text and sent to the district manager's station simultaneously with the wireless signaling; the district manager's station receives the wireless signaling and converts the voice text into synthesized speech before broadcasting it to the handheld terminal.

[0016] In one embodiment, the status feedback instruction includes at least one of route processing start, route processing complete, waiting to pass, stopping and turning back, connection, and route failure.

[0017] In one embodiment, when the method is used for multiple independent shunting groups, the method further includes: assigning independent identification information to each shunting group and compiling shunting operation orders respectively; each shunting operation order includes the corresponding identification information; and the operation request signaling includes the corresponding identification information.

[0018] The present invention also provides a shunting operation control system, comprising: a centralized dispatching system for generating shunting operation orders and performing corresponding route control or safety status checks; a horizontal shunting system connected to the centralized dispatching system via an interface server; the horizontal shunting system including at least one handheld terminal for receiving and displaying the shunting operation orders, sending operation request signaling, and receiving status feedback instructions; and a section chief's station connected to both the handheld terminal and the interface server for receiving operation request signaling sent by the handheld terminal and forwarding the operation request signaling to the interface server; the interface server for converting the operation request signaling into standard signaling recognizable by the centralized dispatching system and sending it to the centralized dispatching system, or converting the status feedback instructions into wireless signaling and voice / text and sending it to the section chief's station.

[0019] In one embodiment, the district administrator's console is also configured to convert voice text from the interface server into synthesized speech.

[0020] In one embodiment, the handheld terminal is provided with specific operation buttons or button combinations for triggering the sending of the job request signaling.

[0021] In one embodiment, after receiving a first signaling command to request shunting, the centralized scheduling system automatically searches for and arranges shunting routes that meet the safety interlocking conditions; or after receiving a second signaling command to request reversal, it checks the locking status of switches and / or the occupancy status of routes on the reversal or turnaround path, and feeds back the check results to the interface server.

[0022] In one embodiment, the handheld terminal further includes a local storage unit for storing and querying historical shunting operation orders.

Detailed Implementation

[0030] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the shunting operation control method and system proposed in this invention. The advantages and features of this 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, intended only to facilitate and clearly illustrate the embodiments of this invention. Please refer to the drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this 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 this invention, should still fall within the scope of the technical content disclosed in this invention.

[0031] As railway transportation develops towards intelligence and informatization, the existing manual-based shunting control methods are gradually becoming inadequate to meet the requirements of improved transportation efficiency and enhanced safety. To overcome these shortcomings, this invention provides a shunting operation control system, such as... Figure 1 As shown, the shunting operation control system 100 includes: a centralized dispatching system (CTC) 101, used to generate shunting operation orders and perform corresponding route control or safety status checks; a horizontal shunting system 103, connected to the centralized dispatching system 101 via an interface server 102; the horizontal shunting system 103 includes at least one handheld terminal 131, used to receive and display the shunting operation order, send operation request signaling, and receive status feedback instructions; a section chief station 132, connected to both the handheld terminal 131 and the interface server 102, used to receive the operation request signaling sent by the handheld terminal 131 and forward the operation request signaling to the interface server 102; the interface server 102 is used to convert the operation request signaling into standard signaling recognizable by the centralized dispatching system 101 and send it to the centralized dispatching system 101, or to convert the status feedback instructions into wireless signaling and voice / text and send it to the section chief station 132. In this embodiment, the shunting operation control system 100 supports two-way communication. The operation request signaling sent by the handheld terminal 131 includes a first signaling for requesting shunting and a second signaling for requesting reversal.

[0032] In some embodiments, such as Figure 1As shown, the handheld terminal 131 is a shunting handheld console, which is an interactive terminal for shunting site operators. The handheld terminal 131 includes an interface display unit, a button operation unit, and a voice receiving unit. The interface display unit is used to receive and display shunting operation orders issued by the centralized dispatching system 101, replacing traditional paper documents. The button operation unit includes specific operation buttons or button combinations, which are located on the handheld terminal 131 and used to trigger the sending of the operation request signal. The voice receiving unit is a speaker located within the handheld terminal 131, used to play synthesized voice to prompt shunting personnel to perform corresponding shunting operations. Furthermore, the handheld terminal 131 also includes a local storage unit to enable local storage functionality for storing and querying historical shunting operation orders.

[0033] In some embodiments, such as Figure 1 As shown, the zone chief station 132, acting as the ground base station of the wireless planar shunting system 103, is responsible for wireless communication (signaling and voice relay) with all handheld terminals 131 within its jurisdiction. The wireless communication includes receiving work request signaling sent by the handheld terminals 131 and forwarding the work request signaling to the interface server 102; simultaneously, the zone chief station 132 receives voice text sent by the interface server 102, and the zone chief station 132 is also used to convert the voice text into synthesized speech and broadcast it to the handheld terminals 131.

[0034] In some embodiments, such as Figure 1 As shown, the interface server 102 is the core processing unit of the shunting operation control system 100, and its core responsibilities include protocol conversion, logical judgment, command text generation, and operation isolation. Specifically, the protocol conversion involves converting operation request signaling (wireless signaling) from different zone chief stations 132 into standard signaling recognizable by the centralized dispatching system 101, and vice versa, converting the status feedback instructions sent by the centralized dispatching system 101 into wireless signaling and voice text recognizable by the zone chief stations. The logical judgment involves combining the shunting plan with the real-time station status to analyze the intent of the operation request signaling, such as distinguishing between "requesting shunting" (for route processing) and "requesting reversal" (for route inspection). Command text generation refers to automatically generating voice text to be broadcast based on the status feedback instructions sent by the centralized dispatching system 101. Operation isolation ensures that operation instructions from multiple shunting groups do not interfere with each other by identifying different zone chief stations 132 or their identification information.

[0035] In some embodiments, the centralized dispatching system 101 is used for shunting operation order generation, automatic route control, and safety status checks. The shunting operation order generation is based on available wagons, route status, shunting plans, locomotive operation information, etc., where available wagons refer to wagons currently parked at the station. Automatic route control refers to the centralized dispatching system 101 automatically searching for and arranging shunting routes that meet safety interlocking conditions after receiving a first signal requesting shunting. Safety status checks refer to the centralized dispatching system 101 checking the locking status of switches and / or route occupancy on the reversing or turning-back path after receiving a second signal requesting a reversal, and feeding back the check results to the interface server 102 as the basis for generating a voice response.

[0036] Based on the shunting operation control system 100 provided in the above embodiments, this embodiment of the invention also provides a shunting operation control method, such as... Figure 2 As shown, the method includes: a centralized dispatching system 101 dynamically and in real-time pushes shunting operation orders to at least one handheld terminal 131 through an interface server 102 and a district manager's station 132; the shunting operation order is dynamically displayed on the display interface of the handheld terminal 131; the handheld terminal 131 triggers an operation request signaling according to the shunting operation order; the operation request signaling is sent to the centralized dispatching system 101 via the district manager's station 132 and the interface server 102; the centralized dispatching system 101 responds to the operation request signaling by performing corresponding route control or safety status check operations; the centralized dispatching system 101 generates a status feedback instruction based on the result of the route control or safety status check operation, and sends it to the handheld terminal 131 via the interface server 102 and the district manager's station 132, broadcasting it to the shunting team and / or driver in voice form, forming an operation closed loop. This method achieves automated transmission and execution of shunting operation plans and instructions through wireless communication between the centralized scheduling system 101, interface server 102, zone manager's station 132, and handheld terminal 131, significantly reducing the safety risks caused by human error and communication delays.

[0037] The shunting operation information on the shunting operation order includes at least one of the following: order number, locomotive number, train number, horizontal shunting number, operation plan start time, operation plan end time, shunting sequence number, track, direction, number of cars, and operation precautions. In some embodiments, the centralized dispatching system 101 generates a corresponding shunting operation order based on the above shunting operation information and sends it to the corresponding handheld terminal 131. When the shunting operator receives the notification of the shunting operation order, the shunting operator views the shunting operation order and completes the connection operation on the shunting operation order, and triggers the operation request signaling according to the shunting operation order. The operation request signaling includes a first signaling for "requesting shunting" and a second signaling for "requesting reversal". The first signaling for "requesting shunting" or the second signaling for "requesting reversal" is transmitted wirelessly by the handheld terminal 131 to the district manager's station 132, and then sent to the interface server 102 through the district manager's station 132. By establishing an automated route control mechanism based on signaling interaction, intelligent response and linkage control of shunting routes were achieved, improving the speed and accuracy of operational response.

[0038] The transmission direction of the work request signaling is from the area controller's station 132 to the centralized dispatching system 101. The triggering condition for the first signaling is that the shunting group has completed the intra-line connection operation, and there are no abnormalities at the current work position, providing the basic conditions for processing a route from the current position to the planned next position. At this time, the dispatcher operates the operation button on the handheld terminal 131 to send the first signaling "request shunting". This first signaling is sent to the centralized dispatching system 101. The centralized dispatching system 101 receives confirmation that the connection operation is completed. Based on the triggering condition of the first signaling, the centralized dispatching system 101 responds to the first signaling by performing the corresponding route control operation, which involves processing the shunting route, including: processing the shunting route from the current work position to the planned next work position based on the shunting work order.

[0039] Furthermore, the triggering condition for the second signaling is that the shunting group has completed the connection operation within the line, but the planned operating line has insufficient capacity to accommodate the locomotive and rolling stock currently in operation, requiring a reversal and return. In some embodiments, when the line capacity is insufficient to accommodate the locomotive / rolling stock currently in operation, and the locomotive still cannot enter the line after the connection operation is completed, requiring a reversal and return, the dispatcher operates the operation button on the handheld terminal 131 to send a second signaling "request to reverse". This second signaling is sent to the dispatching centralized system 101. The dispatching centralized system 101 responds to the second signaling by performing corresponding safety status checks, including: not processing the route, checking the locking status of the switches and / or the route occupancy on the reversal or return path, and feeding back the check results to the interface server 102 as the basis for generating a voice response; or processing a shunting route to reverse from any location; or confirming that all switches on the reversal route are in the locked state, and replying to the shunting operator via voice to allow the reversal.

[0040] The "not processing a route" is a routine operation in response to the "request to retreat" signal, while the "processing a shunting route to retreat from any location" is a special operation in response to the "request to retreat" signal. The two are complementary to each other, and the triggering conditions for the special situation include at least the following: the route behind the locomotive needs to pass through one or more sets of switches, and these switches are not locked in the required positions, so a shunting route from the current locomotive position to the target track needs to be processed to lock all switches on the path; or the retreat distance is too long or exceeds the visual range, so a shunting route needs to be processed to rely on interlocking equipment to ensure that the sections in the entire retreat route are free (track circuit occupancy check) and the switches are in the correct positions, etc.

[0041] In some embodiments, by negotiating with the centralized scheduling system 101, an operation signaling is specified in the idle signaling that is not enabled on the handheld terminal 131, defined as "request shunting" or "request reversal". Since the first signaling for "request shunting" or the second signaling for "request reversal" will not be used simultaneously, the first signaling and the second signaling use the same idle signaling code at the wireless transmission layer sent from the handheld terminal 131 to the district station 132, and are parsed and distinguished by the interface server 102 in conjunction with the operation stage.

[0042] Furthermore, during the transmission of status feedback instructions, the transmission direction of the status feedback instructions is from the centralized dispatching system 101 to the district manager's station 132. During this transmission, voice commands are generated to implement shunting operations. The voice commands refer to information related to shunting command generated by the centralized dispatching system 101, which is communicated to the shunting operator / driver via the voice channel of the district manager's station 132 in the planar shunting system 103. This includes responses from the shunting operator to the first signal "request shunting" or the second signal "request reversal." The content of the status feedback instructions is related to routes and train operation, including at least one of the following: route processing commencement, route processing completion, waiting, stopping and turning back, connection, and route failure.

[0043] In some embodiments, the voice broadcast to the shunting crew and / or driver includes the following steps: the centralized dispatching system 101 sends the status feedback instruction to the interface server 102; the interface server 102 parses the status feedback instruction to generate wireless signaling; simultaneously, it converts the status feedback instruction into corresponding voice text, and sends the voice text and the wireless signaling together to the district station 132; the district station 132 receives the wireless signaling and converts the voice text into synthesized speech before broadcasting it to the handheld terminal 131. The handheld terminal 131 plays the message through its built-in speaker, allowing the user to receive the command information through their ears. This method achieves full-process voice command and status feedback, enhancing the information reception capabilities of operators in complex environments and ensuring that no critical instructions are missed.

[0044] In one specific embodiment, such as Figure 2 As shown, Figure 2 This demonstrates the closed-loop control of the entire shunting operation process, from the issuance of the plan to the execution of the instruction, specifically including the following steps: Step 201: The dispatching centralized system 101 generates a shunting operation order, the content of which is to connect 5 cars from track 3 to track 7, and to carry out car unloading operations on track 7. Step 202: Through the centralized dispatch system 101, the duty officer sends the shunting operation order to the shunting operator's handheld terminal 131 via the interface server 102 and the district manager's station 132 and displays it. Step 203: After the shunting operator completes the connection of the three tracks, if it is necessary to open the shunting route, press the "Request Shunting" combination key on the handheld terminal 131. Step 204: The first signaling message for "requesting dispatching" is transmitted to the centralized dispatching system 101 via the district chief's station 132 and the interface server 102. Step 205: The dispatching centralized system 101 automatically processes shunting routes from track 3 to track 7 and sends the route processing status text (such as "Route arranged, signal open") as the status feedback instruction to the district chief's station. Step 206: The district chief station 132 converts the processing status text into voice and broadcasts through the flat shunting system 103 that the route has been arranged and the train can be moved to track 7. Step 207: After hearing the voice command, the shunting team directs the locomotive to move and complete the shunting operation. Step 208: If it is not necessary to open the shunting route, determine whether it is necessary to turn back. If it is necessary to turn back, press the "Request Reverse" combination key on the handheld terminal 131. Step 209: The second signaling message for "requesting back" is transmitted to the centralized scheduling system 101 via the district chief's station 132 and the interface server 102. Step 210: The centralized dispatch system 101 checks the fallback path and confirms via voice. Step 211: After hearing the voice command, the shunting team directs the locomotive to move and complete the turnaround operation. Step 212: If it is not necessary to turn back, the shunting operator receives a voice command via handheld terminal 131 to ask whether to continue the operation. If it is necessary to continue the operation, the operation will restart from step 203. Step 213: If the shunting operator receives a voice command via handheld terminal 131 indicating that no work is required, the work is stopped and the process ends.

[0045] In another embodiment, the shunting operation control method also supports parallel operation command of multiple independent shunting groups. The method further includes: assigning independent identification information to each shunting group and compiling separate shunting operation orders; each shunting operation order contains the identification information corresponding to each shunting group; and the operation request signaling contains the corresponding identification information. This method supports parallel operation of multiple shunting groups and differentiated command. The centralized dispatching system 101 can implement differentiated signaling distribution and voice command based on the section chief's station 132 corresponding to different shunting groups or locomotives, supporting the parallel execution of multiple shunting operations and improving the overall efficiency and coordination of station shunting operations. Specifically, as shown... Figure 3 As shown, taking the parallel operation of shunting group A and shunting group B as an example, the steps include: Step 301: The centralized dispatching system 101 assigns independent logical identification information to each shunting group to distinguish between shunting group A and shunting group B, and compiles shunting operation orders for each group. Step 302: The shunting operation order for each shunting group is issued to the corresponding handheld terminals of Group A and Group B respectively; Step 303: The shunting operators of Group A and Group B shall carry out the work according to the plan on the shunting work order and send the first / second signal (request shunting / reverse) through the handheld terminal when necessary. Step 304: The first / second signaling contains the identification information (group identifier) ​​corresponding to each shunting group, which is transmitted to the interface server 102 via the district chief station 132; Step 305: The interface server 102 transfers the first / second signaling to the corresponding processing logic for processing according to the group identifier, and sends corresponding control instructions to the scheduling central system 101 respectively. Step 306: The centralized scheduling system 101 processes the route requests of each group and sends the corresponding status feedback instructions to the interface server 102. Step 307: The interface server 102 generates the corresponding group's voice text according to the status feedback instruction and sends it to the district chief's station 132; Step 308: At the district chief's station 132, according to the group identifier, the voice is broadcast to each group through the handheld terminal of the different group; Step 309: Upon hearing the instructions from their respective groups, the shunting operators of Group A and Group B shall carry out the operation.

[0046] Furthermore, to clearly describe the protocol conversion function in the interface server of this invention, such as... Figure 4 As shown, taking shunting operations at a certain station as an example, the steps include: Step 401: After the shunting operator completes the 3-track connection operation, he / she presses the "Request Shunting" combination key on the handheld terminal 131. The handheld terminal 131 generates a wireless signaling message. The specific content of the wireless signaling message is: frame header 0xAA55 + group identifier 0x01 (shunting group A) + signaling code 0x0A (idle signaling, carrying request shunting) + check bit 0x3F. Step 402: The district chief station 132 receives the wireless signaling (transmitted through a wireless channel, conforming to the relevant specifications of station wireless communication equipment), does not modify the protocol, and directly forwards the original signaling to the interface server 102 through the network; Step 403: The protocol conversion module of interface server 102 performs forward conversion, including: S431, parsing the original signaling: first, verifying the check bit 0x3F to confirm that the signaling transmission is correct; then extracting the group identifier 0x01 (identified as shunting group A) and the signaling code 0x0A; S432, parsing the intent in conjunction with the operation stage: interface server 102 retrieves the current shunting operation plan (the shunting operation order issued by the dispatching centralized system 101 to interface server 102, which includes "connecting track 3 and then transferring to track 7"), and determines that shunting group A has completed the connection operation at this time, so the signaling code 0x0A is parsed as "requesting shunting" intent; S433, format conversion: converting the parsed "requesting shunting" intent into ASCII code signaling that can be recognized by the dispatching centralized system 101, specifically: instruction type 01 (processing shunting route) + operation position 000307 (current track 3 → next position track 7) + status identifier 01 (normal request) + check code 1234; Step 404: Interface server 102 sends the converted CTC standard signaling to dispatching centralized system 101 via the network to complete the forward protocol conversion and ensure that dispatching centralized system 101 accurately receives shunting route processing requests. Step 405: After receiving the first "Request Shunting" signal forwarded by the interface server 102, the dispatching centralized system 101 automatically processes shunting routes from track 3 to track 7. After completion, it generates a status feedback instruction, specifically: instruction type 03 (route processing feedback) + operation position 000307 + status identifier 02 (route arranged) + check code 5678 (ASCII code format). Step 406: The centralized dispatching system 101 sends the status feedback instruction to the interface server 102. The protocol conversion module of the interface server 102 performs reverse conversion: S461, Parse the status feedback instruction: verify the check code 5678 to confirm that the instruction is correct; extract instruction type 03 and status identifier 02, and parse it into the feedback information "Route arranged, signal open"; S462, Format conversion: convert the feedback information into the wireless signaling format of the plane shunting system 103, specifically: frame header 0xAA55 + group identifier 0x01 (shunting group A) + signaling code 0x0B (agreed "route completed" signaling) + check bit 0x4D (binary format); S463, Associate with voice command text: synchronously convert "Route arranged, signal open" into the corresponding text, and forward it to the district chief station 132 together with the converted wireless signaling. Step 407: The section chief station 132 receives the converted wireless signaling and text, converts the text into synthesized speech, and broadcasts it to the handheld terminal 131 of shunting group A through the wireless channel, completing the reverse protocol conversion and realizing the closed-loop transmission of instruction feedback.
