Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to an intelligent barrier and warning method for construction and maintenance areas of technical stations. Background Technology

[0002] Marshalling yards, section yards, and other railway technical stations are characterized by multiple connecting directions, complex station throats, numerous special-purpose lines, and a large variety and quantity of equipment. They are characterized by high train arrival and departure density, strained throat area capacity, limited track capacity, and numerous locomotive changing and loading / unloading operations. With the continuous increase in new line construction, existing line renovation, and routine equipment maintenance, the daily construction and maintenance work at these technical stations is also constantly increasing. It has become common for construction / maintenance work to be carried out simultaneously in different areas within the yard, and for some areas of the same throat area to be under construction / maintenance while other areas continue normal train operation. This presents significant challenges to construction / maintenance safety and transportation production organization.

[0003] In terms of train operation organization, the technical station's safety protection for the closed areas of construction and maintenance equipment mainly relies on the human-machine interface of control systems such as computer interlocking systems, hump yard automation control systems, railway dispatching centralized systems, and marshalling yard integrated automation systems. This is achieved by manually blocking switches, signals, tracks, and speed reducers to prevent the interlocking conditions for route arrangement from being met, thus ensuring the safety of trains and shunting operations. For situations where maintenance areas or overhead contact line areas cannot be controlled by signal interlocking conditions, the control system provides a means of manually marking the scope of closure, preventing the incorrect departure of train and shunting routes based on the transportation safety conditions stipulated in the station regulations.

[0004] In response to the fact that the basic data of the maintenance area and the overhead contact line area are maintained by the train operation department rather than the signaling department, the Communication and Signaling Research Institute of China Academy of Railway Sciences Group Co., Ltd. developed the train operation maintenance terminal of the marshalling yard integrated automation system in 2018. This transfers the authority to modify and maintain the basic data of the maintenance area and the overhead contact line area from the signaling department to the train operation department, but the data is still stored in the control system database.

[0005] As of the end of 2020, the technical station's construction and maintenance information still had not been able to interact between the information system and the control system. Furthermore, the technical station's safety production command center still lacked the information technology means to conduct safety monitoring and command of construction and maintenance restricted areas, key vehicles, and personnel. Therefore, the following technical problems existed:

[0006] 1) Information about the blocking of construction and maintenance equipment cannot be automatically transmitted between construction duty officers and station duty officers, which poses a potential risk of equipment safety protection failure.

[0007] As the reviewer of the work content and scope of impact of construction and maintenance plans, the construction duty officer uses a terminal managed by the information department, which lacks the function of marking equipment closure areas. Although the station duty officer terminal managed by the electrical department has the function of manually closing switches, tracks, signals, maintenance areas, and overhead contact lines, the division of responsibilities at the technical station determines which equipment needs to be closed and unclosed at each stage of construction and maintenance. When equipment needs to be closed or unclosed, the construction duty officer must notify the station duty officer by telephone, and the station duty officer will then operate manually. With station duty officers handling both train operation and shunting operations, incorrect closure and unclosure of equipment and areas frequently occur, posing a danger to occupational safety and train operation safety.

[0008] 2) The information on the closure of construction and maintenance equipment cannot be automatically converted into constraints that require station dispatchers to prepare phase plans, which affects the quality of the phase plans being fulfilled.

[0009] As the commanders of station transportation operations, station dispatchers lacked automated means to pre-plan the scope of equipment closures for construction and maintenance, and lacked real-time indicators of available transportation capacity in areas with construction and maintenance work. Station dispatchers could only rely on personal experience to estimate the impact of equipment closures on transportation organization, resulting in low objectivity and poor implementation quality in phased plans.

[0010] 3) The technical station lacks the technical means to control the safety status of the entire station's construction and maintenance operations and transportation organization, which is not conducive to the station manager on duty to give centralized and unified command to the safe production of the entire station's transportation.

[0011] As the leader of the station's overall transportation safety, the duty station manager is unable to check the construction and maintenance plans based on the equipment blockade area. He can only record the location of road engineering vehicles and outdoor workers by pen and paper, and can only issue safety warnings for construction and maintenance areas by telephone. This makes it inefficient to warn and direct transportation production during construction and maintenance, and poses a safety risk of inadequate safety monitoring. Summary of the Invention

[0012] The purpose of this invention is to provide an intelligent barrier and warning method for construction and maintenance areas of technical stations, which can realize automatic marking and automatic safety control of equipment barrier areas, and can also provide a basis for accurately preparing phased plans for construction and maintenance periods. In addition, through graphical display methods, the safety risks of construction and maintenance operations can be reduced.

[0013] The objective of this invention is achieved through the following technical solution:

[0014] A method for intelligent lockdown and early warning in a technical station construction and maintenance area, characterized by comprising:

[0015] By interfaceing with the construction planning management system and the maintenance window management system, the text data of the construction and maintenance plans is automatically obtained. After being processed by the text parsing algorithm, the equipment involved in the text data of the construction and maintenance plans is identified. Combined with the time attributes of the construction and maintenance plans, an equipment blocking plan is generated and then pushed to the display devices of other positions in real time through the marshalling yard integrated automation system.

[0016] Once the construction and maintenance plan is reported, the equipment lock-up plan is pushed to the marshalling yard's integrated automation system to achieve automatic lock-up of the corresponding equipment, and the content of the equipment lock-up plan is dynamically displayed by each display device; and the marshalling yard's integrated automation system assists in the preparation of phase plans.

[0017] As can be seen from the technical solution provided by the present invention, on the one hand, by automatically generating equipment blockade plans, the safety risks of incorrect equipment blockade and unblocking are reduced, and the work efficiency of construction duty officers and station duty officers is improved; on the other hand, the introduction of equipment blockade plans and automatic correction based on real-time capacity determination values ​​reduce the workload of station dispatchers and provide support for improving the efficiency and quality of phase plan preparation; in addition, by dynamically displaying the content of equipment blockade plans, key vehicles in adjacent construction and maintenance blockade areas can be automatically alerted, enriching construction and maintenance warning methods, improving construction and maintenance command efficiency, reducing construction and maintenance joint control costs, and providing an important technical means to strengthen the leadership role of the technical station's safety production command center in construction and maintenance.

For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0019] Figure 1 This is an overall framework diagram of an intelligent lockdown and alert method for a technical station construction and maintenance area provided in an embodiment of the present invention;

[0020] Figure 2 This is a schematic diagram provided for embodiments of the present invention in relevant business scenarios. Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] First, the following explanations are provided for the terms that may be used in this article:

[0023] The terms "comprising," "including," "containing," "having," or other similar semantic descriptions should be interpreted as non-exclusive inclusion. For example, including a technical feature element (such as raw material, component, ingredient, carrier, dosage form, material, size, part, component, mechanism, device, step, process, method, reaction conditions, processing conditions, parameter, algorithm, signal, data, product or article of manufacture, etc.) should be interpreted as including not only the expressly listed technical feature element, but also other technical feature elements that are not expressly listed and are well-known in the art.

[0024] This invention addresses the problems existing in the current technical station construction duty officers, station duty officers, station dispatchers, and duty station managers regarding the sealing and security of construction and maintenance equipment. It proposes an intelligent sealing and security method for technical station construction and maintenance areas, automatically converting construction and maintenance plans into equipment sealing plans, achieving automatic marking and automatic security control of equipment sealing areas. The invention also proposes the concept and calculation method of equipment availability coefficients, providing a basis for accurately preparing phased plans for construction and maintenance periods. Furthermore, it proposes a graphical display method for equipment sealing and security information adapted to the technical station construction and maintenance management model, reducing safety risks during construction and maintenance operations.

[0025] The following is a detailed description of the intelligent lockdown and alert method for construction and maintenance areas of technical stations provided by this invention. Contents not described in detail in the embodiments of this invention are prior art known to those skilled in the art. Where specific conditions are not specified in the embodiments of this invention, they shall be performed according to conventional conditions in the art or conditions recommended by the manufacturer. Instruments used in the embodiments of this invention, unless otherwise specified by the manufacturer, are all conventional products that can be purchased commercially.

[0026] The present invention provides an intelligent lockdown and alert method for a technical station construction and maintenance area, which mainly includes the following steps:

[0027] 1) By interfaceing with the construction planning management system and the maintenance window management system, the text data of the construction and maintenance plan is automatically obtained. After being processed by the text parsing algorithm, the equipment involved in the text data of the construction and maintenance plan is identified. The equipment blocking plan is generated by combining the time attributes of the construction and maintenance plan, and then pushed to the display devices of other positions in real time through the marshalling yard integrated automation system.

[0028] In this embodiment of the invention, the closure plan mainly includes: equipment, time, and safety warning information (key points and precautions) contained in the construction and maintenance plan text. Many construction and maintenance plans specify the start and end range of the closure, for example, the text in the plan may specify turnouts 1 to 10. This range actually includes not only turnouts but also track circuits, signals, and other equipment related to the turnouts. It is necessary to parse the text content and determine all the actual equipment that needs to be closed based on the text content.

[0029] 2) After the construction and maintenance plan is reported, the equipment blockade plan is pushed to the marshalling yard integrated automation system to realize the automatic blockade of the corresponding equipment, and the content of the equipment blockade plan is dynamically displayed by each display device; and the marshalling yard integrated automation system assists in the preparation of phase plans.

[0030] Those skilled in the art will understand that the construction and maintenance plan includes a start time and an end time, which are collectively referred to as the planned time. The actual start time may differ from the planned time. Reporting the time is the process of reporting the actual start and end times, which is carried out by the station duty officer based on the actual situation.

[0031] like Figure 1 The diagram shown is a schematic of the overall hardware architecture. The intelligent lockdown and alert method for the construction and maintenance area of ​​a technical station, provided in this embodiment of the invention, is established within the station management information network, as follows: Figure 1 As shown in the lower left corner, network isolation equipment will be added and interfaced with the construction plan management system and maintenance window management system, utilizing existing station equipment and fully integrating with the existing station systems. A backend processing server and database will be added; a construction duty officer management terminal will be added to manage and maintain basic data such as construction areas, overhead contact line areas, and maintenance window areas, and to review and issue construction and maintenance plans as well as automatically generated equipment shutdown plans in case of abnormal situations; a duty station manager terminal will be added to issue construction and maintenance plans, assign station control window points, and uniformly command and monitor construction and maintenance operations.

[0032] The overall hardware architecture described above adopts the following interface methods: 1) Interface with the construction planning management system and maintenance window management system: Ethernet interface with a centrally located network isolation device. 2) Interface with the marshalling yard integrated automation system: Ethernet interface, located within the same network.

[0033] The above describes the overall system structure. The following section introduces the main core technologies of this invention, which mainly include three parts:

[0034] 1. Automatic generation technology for equipment blocking plans.

[0035] The system intelligently identifies the text data of construction and maintenance plans published by the construction plan management system and the maintenance window management system, automatically filters invalid and erroneous information, identifies the equipment impact range described in the text format as specific equipment objects, automatically associates the start and end times of the blockade of different equipment, forms the equipment blockade plan for the construction and maintenance period, and dynamically pushes it to the display devices of other positions according to the progress of construction and maintenance work.

[0036] The equipment includes one or more of the following: turnout, track, signal, speed reducer, parking device, power supply unit object.

[0037] The display devices for other positions include: display terminals that need to obtain the equipment's blocking and warning range in real time; these include: the integrated display screen of the safety production command center, the duty station manager's display terminal, the station duty officer's display terminal, and the construction duty officer's display terminal.

[0038] In this embodiment of the invention, the automatic generation technology of equipment blockade plans shifts the equipment blockade and unblocking operations from the station duty officer position to the construction duty officer position. This allows the construction duty officer to be responsible for the correspondence between the construction and maintenance plan and the blockade area, while allowing the station duty officer to focus on the implementation and execution of the construction and maintenance plan. This aligns with the current construction and maintenance management model of the technical station. By automatically generating equipment blockade plans, the safety risks of incorrect blockade and unblocking of equipment are reduced, and the work efficiency of both the construction duty officer and the station duty officer is improved.

[0039] 2. Automatic calculation technology for equipment availability coefficient.

[0040] The benchmark throughput capacity is based on the daily assessed throughput and decoupling capacity of technical stations. Taking into account the diesel or electric attributes of trains, shunting locomotives, and main locomotives, the train routes and shunting routes affected by the closure of different equipment (all equipment covered in the closure plan, such as switches, tracks, signals, reducers, parking devices, power supply units, etc.) are uniformly converted into the restricted throughput capacity of the affected tracks and sections within the corresponding technical station. The ratio of the restricted throughput capacity to the benchmark throughput capacity is used as the equipment availability coefficient, and the phase plans and main locomotive operation plans of the technical stations in the equipment closure area are automatically constrained according to different train directions and different shunting directions. The phase plans include: train arrival and departure plans, track operation plans, and shunting locomotive operation plans.

[0041] Those skilled in the art will understand that a technical station is a general term for marshalling yards and section stations, and is a station that handles technical operations for freight trains.

[0042] In this embodiment of the invention, the constraints on the service aircraft operation plan are mainly imposed on the start and end times of the service aircraft operation plan.

[0043] In this embodiment of the invention, by automatically calculating the equipment availability coefficient, the impact of blocking different types of equipment such as turnouts, tracks, signals, reducers, parking devices, and power supply units is converted into constraints and limitations for compiling phase plans. The system is then automatically corrected based on real-time capacity lookup values, which reduces the workload of station dispatchers and provides support for improving the efficiency and quality of phase plan compilation.

[0044] 3. Dynamic graphic technology for construction and maintenance closure and warning information.

[0045] Using the station's signal layout as the base map for graphical display, the system tracks and locates road engineering vehicles in real time during storage and operation. It provides safety warnings for key vehicles near construction and maintenance areas, marks the locations of outdoor workers in real time, and links construction and maintenance plans, equipment blockade areas, and safety alerts. It displays the equipment blockade range in real time for the current moment and a period of time to come, and allows users to directly view detailed information about construction and maintenance plans and safety alerts through the equipment blockade range.

[0046] The equipment lockdown scope is a set of equipment and lockdown times generated according to the equipment lockdown plan. Each plan in the construction and maintenance plan includes not only the scope and time of construction and maintenance, but also relevant key points and precautions (i.e., safety warning information).

[0047] In this embodiment of the invention, the dynamic graphic display technology of construction and maintenance blockade and warning information enables the graphical display of equipment blockade and safety warning information of the technical station centered on the duty station chief. It centrally releases safety warning information, displays the content of construction and maintenance plans, the scope of equipment blockade areas, and the items in the safety warning information, and dynamically tracks the location of road-use engineering vehicles. It automatically alerts key vehicles near the construction and maintenance blockade area, enriching the warning methods for construction and maintenance, improving the efficiency of construction and maintenance command, and reducing the cost of joint control of construction and maintenance. This provides an important technical means to strengthen the leadership role of the technical station's safety production command center in construction and maintenance.

[0048] The following section will introduce the above solutions using specific business scenarios as examples.

[0049] like Figure 2 The diagram shown is a schematic representation of a business scenario.

[0050] First, by interfaceing with the construction plan management system and the maintenance window management system, the text data of the construction and maintenance plans is automatically obtained. After being processed by the text parsing algorithm, the equipment information involved in the construction and maintenance plans is identified, and an equipment blocking plan is generated by combining the time attributes of the construction and maintenance plans.

[0051] The device blocking plan automatically pushes notifications to display devices in other work areas in real time, such as... Figure 2 The front-end display components shown include: the integrated display screen of the safety production command center, the duty station manager's display terminal, the station duty officer's display terminal, the construction duty officer's display terminal, and other display terminals required to obtain the equipment blockade and warning range. Construction duty officers use the terminals provided by this technology to maintain basic data such as equipment information, construction areas, and power outage units within the station. After reporting the location, each display device then graphically displays the blocked area.

[0052] Simultaneously, a dynamic graphic display technology for construction and maintenance closure warning information is adopted. Using the station's signal layout plan as the base map, it centrally displays the content of the construction and maintenance plan, the scope of the equipment closure area covered by the plan, and the safety warning information items within the plan. It also dynamically tracks the location of road maintenance vehicles and automatically alerts road maintenance vehicles located near the equipment closure area. These road maintenance vehicles near the equipment closure area include: road maintenance vehicles whose location is less than a set value (which can be set based on actual conditions or experience), and road maintenance vehicles whose routes are pointing towards the closure area.

[0053] After the station duty officer reports the construction and maintenance plan, the system automatically selects the equipment closure plan information involved in the plan, processes it into equipment information that the control system can recognize, and pushes it to the marshalling yard integrated automation system to achieve automatic equipment closure without manual operation. When the marshalling yard integrated automation system performs the automatic calculation function, it provides the equipment closure plan that is currently being executed and converts it into tracks and lines, which participate in the automatic calculation process. For details on the specific principle, please refer to the introduction of the automatic calculation technology of equipment availability coefficient mentioned above.

[0054] The above-described solutions in the embodiments of the present invention mainly achieve the following beneficial effects:

[0055] 1) It can standardize the work processes of construction duty officers and station duty officers at technical stations, filling the current technical gaps in construction and maintenance safety management at technical stations; by establishing a calculation system for equipment availability coefficients and digitizing transportation resources, it will play an important auxiliary role in improving the quality of construction and maintenance plans and daily shift plans; by building a dynamic graphic sharing platform for construction and maintenance plans, the safety production command center will radiate to all departments at technical stations involved in construction and maintenance operations, and improve the safety of construction and maintenance operations with rich, intuitive, consistent, and accurate graphic display interfaces.

[0056] 2) The text information of the construction and maintenance plan is mapped to the station equipment, the construction and maintenance plan is analyzed from a new perspective, the equipment blockade plan is automatically generated and pushed to the control system, and the control system generates equipment blockade instructions.

[0057] 3) The concept of equipment availability coefficient is proposed to establish a relationship between the scope of influence of construction and maintenance plans and the transportation resources that need to be considered in the preparation of phase plans. This reduces the quality gap in phase plan preparation caused by different dispatchers' business capabilities and provides important support for the automatic preparation function of phase plans in the marshalling yard integrated automation system.

[0058] 4) It comprehensively displays information on trains, shunting locomotives, main locomotives, key vehicles, track engineering vehicles, equipment closure areas, and the location of outdoor workers, providing stations with a unified human-machine interface for centralized closure and warning of construction and maintenance areas.

Based on this understanding, the technical solutions of the above embodiments can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (such as a CD-ROM, USB flash drive, mobile hard drive, etc.), including several instructions to cause a computer device (such as a personal computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.
