Description

Technical Field

[0001] This invention relates to the field of rail transit, specifically to a safety control system and method for train reception and dispatch operations. Background Technology

[0002] The Safety Production Command Center of the Railway Station Section is the organization responsible for the command and coordination of safety production within the railway station section. It is responsible for the unified coordination and command of transportation safety production throughout the section. Currently, the staff of the command center mainly rely on remote video and audio inspections to carry out their work. They are unable to keep abreast of the key safety operations that the station is about to carry out or is currently carrying out, as well as abnormal situations. They rely on station notifications or spot checks to monitor and control the situation, which makes it impossible to avoid safety hazards in a timely manner.

[0003] The railway operations section or directly affiliated station bears management responsibility for whether the personnel at each station are violating operating procedures. Especially with the increase in new station staff and signalmen in recent years, safety risks have increased significantly. Therefore, the railway operations section has assigned experienced personnel to its safety production command center to provide on-site guidance. This approach has been very effective, but the following problems still exist:

[0004] First, problems cannot be detected in a timely manner. The train operation section cannot know in a timely manner about the critical safety operations that the station will be carrying out or is currently carrying out (such as speed limit requiring train-machine joint control) and abnormal situations (such as switch malfunctions, abnormal red light bands, etc.). Monitoring is achieved through station notifications or spot checks, which cannot avoid safety hazards in a timely manner.

[0005] Secondly, emergency response is prone to errors because there are many abnormal scenarios that occur randomly, and most operators lack experience in handling them. Therefore, it is easy to make mistakes in the response after an incident occurs.

[0006] Finally, there are difficulties in post-event analysis. Currently, methods such as replaying videos, audio, and station maps are used for analysis. However, firstly, these data come from different systems, requiring manual location and synchronous playback; secondly, there is no recorded data on operational procedures, which brings certain difficulties to comprehensive analysis. Summary of the Invention

[0007] The purpose of this invention is to design a safety management and control system for train reception and dispatch operations, enabling train reception and dispatch safety monitors at the station's safety production command center to shift from manual inspections and spot checks to proactive reminders and alarms from equipment, thereby improving the level of safety management and control for train reception and dispatch operations.

[0008] This invention provides a safety management and control system for train reception and dispatch operations, including: an identification module, which is used to predefine risk rules and form a risk list for each risk management item of key operations, key trains, equipment failures and high-risk operations;

[0009] The alarm module, which is connected to the risk identification module, is used to issue alarms for monitored risk control items;

[0010] The monitoring module, which is connected to the risk alarm module, is used to monitor the operation process of risk control items in real time after a risk alarm is triggered.

[0011] The statistical analysis module is used to perform statistical analysis and playback analysis of data from risk alarms and monitoring processes.

[0012] Furthermore, key operations include: construction closures, comprehensive maintenance, and speed limits for transport and unloading;

[0013] Key trains include: special trains with oversized, military, inspection, or return routes; temporary trains, temporarily adjusted trains, and non-scheduled trains that are recorded according to telegraphic messages;

[0014] Equipment malfunctions include: switch malfunction, abnormal signal shutdown, and abnormal red light band;

[0015] High-risk operations include: violating Article 301 of the technical regulations, operating locomotives without separation, safety line switches not being in position, and arranging routes through sections with poor branching.

[0016] Furthermore, the alarm content includes:

[0017] An alarm for key tasks is generated when key tasks do not match the plan.

[0018] An alarm for a key train is triggered when the actual operation of a key train deviates from the plan.

[0019] Equipment fault alarms generated when the equipment status is inconsistent with the normal or planned status;

[0020] High-risk operation alarms are generated when the high-risk operation is inconsistent with the normal state.

[0021] Furthermore, the key operations include: the actual control measures and the movement of engineering vehicles during construction closures and comprehensive maintenance operations, including the closure area, turnout positions, and turnout locking status.

[0022] Furthermore, the operational status of key trains includes: the planned arrival and departure status, the actual arrival and departure status, and the status of overloaded vehicles accessing the track.

[0023] Furthermore, the equipment fault alarm includes alarms generated when the real-time detected status of turnouts, signal lights, and red light strips is inconsistent with the normal or planned status.

[0024] Furthermore, high-risk operation alarms include alarms generated when passenger, freight, and enterprise locomotive train arrival and departure routes are not separated, when safety line switches are in operation, or when the equipment occupancy status on the route is inconsistent with the normal status.

[0025] Furthermore, the monitoring interface provided by the monitoring module provides, after the risk control operation begins, real-time station information, key operation plan information, control measure plan and comparison information, engineering vehicle travel plan and comparison information, and train arrival and departure plan information for the current operation within three hours.

[0026] Furthermore, the statistical analysis module includes: time-based playback, acceleration, deceleration, and dragging functions for risk control items; statistical functions for the number of dispatched trains, vehicles, and workload; and functions for recording and statistically analyzing the monitoring status of risk control items, equipment failures, and abnormal situations.

[0027] Furthermore, the system also includes:

[0028] The external interface module is used to receive operation diagram data, station diagram data, dispatching commands, station events and alarms, and construction plans;

[0029] Several terminals, including vehicle arrival and departure monitoring terminals, information analysis terminals, professional department review terminals, duty officer terminals, and monitoring cadre terminals.

[0030] Furthermore, the train arrival and departure monitoring terminal, information analysis terminal, and professional department review terminal are all located in the command center, while the duty officer terminal and monitoring cadre terminal are all located at the station.

[0031] Furthermore, the dispatch and reception monitor at the command center can use the dispatch and reception monitoring terminal to grasp the risk management plan for their shift, monitor the execution process of risk management items, and handle risk alarms.

[0032] Furthermore, the information analyst at the command center uses the information analysis terminal to statistically analyze the workload of train dispatching and receiving operations within the railway section, the work quality of station and command center personnel, and the number of alarms related to equipment malfunctions and abnormal operations.

[0033] Furthermore, the relevant professional departments of the railway station review the risk control list within the terminal's jurisdiction and the construction control measures and engineering vehicle travel plans submitted by the station.

[0034] Furthermore, the station duty officer receives risk control items, equipment failure alarms, and high-risk operation alarms issued by the station command center through the station duty officer terminal; and inputs the control measures and engineering vehicle travel plans during station construction through the station duty officer terminal.

[0035] Furthermore, station monitoring officers can use the station monitoring officer terminal to understand the on-site operation situation and confirm the progress of key operations during key operations.

[0036] In addition, the present invention also provides a safety management method for train reception and dispatch operations, comprising the following steps:

[0037] S1. Generate a risk list for each risk control item;

[0038] S2. Based on the risk list, generate a risk control chart and automatically remind the monitor to start monitoring according to the start and end times of each risk control item;

[0039] S3. Determine the status of risk control items and generate an alarm if the status is abnormal;

[0040] S4. After receiving the alarm, the command center monitoring personnel will monitor the station's operations and emergency response, and provide auxiliary guidance.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. It provides train dispatch safety monitors at train stations with the means to identify risks in advance and monitor train dispatch operations in a planned manner.

[0051] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the safety management system and method for train reception and dispatch operations proposed in this invention. The advantages and features of this invention will become clearer from the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the embodiments of this invention. Please refer to the accompanying 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.

[0052] like Figure 1 The diagram shown is a structural block diagram of a train arrival and departure operation safety management system provided by the present invention. The system includes an identification module, an alarm module, a monitoring module, and a statistical analysis module. The identification module is used to generate a risk list for each risk management item according to predefined risk rules, including risk lists for key operations, key trains, equipment failures, and high-risk operations. The alarm module is connected to the risk identification module and is used to issue alarms for monitored risk management items, and is also communicatively connected to the monitoring module. The monitoring module is used to monitor the operation process of the risk management item in real time after a risk alarm. The statistical analysis module is used to perform data statistics and playback analysis on the risk alarm and monitoring process. The alarm module can also automatically generate a risk management map based on key operations and key trains in the risk list, combined with the start and end times, stations, and management content of each risk management item.

[0053] Key operations include construction closures, comprehensive maintenance, and speed restrictions during transport. Each key operation has preset rules, and the alarm module compares the execution process of the key operation with the rules; an alarm is generated if there is a discrepancy. Key trains include special trains with over-limit, military, inspection, or return routes, as well as temporary trains, temporarily adjusted trains, and non-scheduled trains recorded by telegraphic message. The alarm module compares the status of key trains with their planned status; an alarm is generated if there is a discrepancy. Equipment malfunctions include: switch malfunctions, abnormal signal shutdowns, and abnormal red light bands. The alarm module compares the equipment with its normal or planned status; an alarm is generated if there is a discrepancy. High-risk operations include violations of Technical Regulations 301, unseparated locomotive operations, safety line switches not being positioned, and routes passing through poorly separated sections.

[0054] As can be seen from the above, the alarm content includes: key operation alarms generated when key operations are inconsistent with the plan; key train alarms generated when the operation status of key trains is inconsistent with the plan; equipment failure alarms generated when the equipment status is inconsistent with the normal or planned status; and high-risk operation alarms generated when high-risk operations are inconsistent with the normal status.

[0055] Specifically, the key operations include: during construction closures and comprehensive maintenance operations, the actual control measures and the movement of engineering vehicles, including the closed area, turnout positions, and turnout locking status. The alarm module compares the closed area, turnout positions, and turnout locking status with the plan, and generates an alarm if they are inconsistent with the plan.

[0056] The operational status of key trains includes: the planned arrival and departure status, the actual arrival and departure status, and the status of oversized trains entering the track.

[0057] The equipment fault alarms include alarms generated when the real-time detected status of turnouts, signal machines, and red light strips is inconsistent with the normal or planned status.

[0058] High-risk operation alarms include alarms generated when passenger, freight, and enterprise locomotive train arrival and departure routes are not separated, when safety line switches are not in place, and when the equipment occupancy status on the route is inconsistent with the normal status.

[0059] In addition, the monitoring module has a monitoring interface. After the risk control operation begins, the monitoring interface provides information including real-time station information, key operation plan information, control measure plan and comparison information, engineering vehicle travel plan and comparison information, and train arrival and departure plan information for the current operation within three hours.

[0060] The statistical analysis module includes: time-based playback, acceleration, deceleration, and dragging functions for risk control items; statistical functions for the number of dispatched trains, vehicles, and workload; and functions for recording and statistically analyzing the monitoring status of risk control items, equipment failures, and abnormal situations.

[0061] Furthermore, such as Figure 2 The diagram illustrates the train arrival and departure operation safety management system and its external interface as described in this invention. The system further includes an external interface module and several terminals. The external interface module receives train operation data, station map data, dispatching commands, station events and alarms, and construction plans. The terminals include a train arrival and departure monitoring terminal, an information analysis terminal, a professional department review terminal, a duty officer terminal, and a monitoring officer terminal.

[0062] The train arrival and departure operation safety management system provided by this invention obtains information such as train number, type, stage plan, and actual arrival and departure from the train timetable. Based on predefined risk identification rules, it can automatically identify and mark key train numbers and stations. By obtaining real-time station layout, red light zone occupancy, train numbers, and route arrangements from the station map, it can identify equipment malfunctions and abnormal operating conditions, issuing real-time alarms. Furthermore, by obtaining information such as dispatch order title, type, recipient location, and order content from dispatch orders, it can identify key trains such as those exceeding length or size limits, and information such as changes in train arrival and departure points, automatically identifying and marking risks. Additionally, by obtaining real-time information such as station login personnel and operational error alarms from station events and alarms, it can promptly identify key personnel and operational errors, providing early warnings. Finally, by obtaining the next day's construction plan from the construction schedule, it automatically filters information such as construction type, construction level, involved stations, and impact range to form planned risk monitoring priorities for real-time management. Furthermore, by comparing the real-time train operation and equipment status on site with the pre-identified risk control plan, standard operating status, and normal equipment status, alarm information or prompts are promptly released to various terminals.

[0063] The train arrival and departure monitoring terminal, information analysis terminal, and professional department review terminal are all located in the command center, while the duty officer terminal and monitoring cadre terminal are all located at the station.

[0064] The command center's train dispatch monitoring personnel use the train dispatch monitoring terminal to monitor the risk control plan for their shift, track the execution of risk control items, and handle risk alarms. Command center information analysts use the information analysis terminal to statistically analyze the workload of train dispatch operations within the railway section's jurisdiction, the work quality of station and command center personnel, and the number of alarms related to equipment malfunctions and abnormal operations. Relevant professional departments within the railway section review risk control items within their jurisdiction using the terminal, and review construction control measures and engineering vehicle travel plans submitted by the stations. Station duty officers receive risk control items, equipment malfunction alarms, and high-risk operation alarms issued by the station command center through the station duty officer terminal; they also input control measures and engineering vehicle travel plans for their station's construction work through the terminal. Station monitoring officers use the station monitoring officer terminal to understand the on-site work situation and confirm the progress of key operations.

[0065] In addition, the present invention also provides a safety management method for train reception and dispatch operations, comprising the following steps:

[0066] S1. Generate a risk list for each risk control item;

[0067] S2. Based on the risk list, generate a risk control chart and automatically remind the monitor to start monitoring according to the start and end times of each risk control item;

[0068] S3. Determine the status of risk control items and generate an alarm if the status is abnormal;

[0069] S4. After receiving the alarm, the command center monitoring personnel will monitor the station's operations and emergency response, and provide auxiliary guidance.

[0070] Specifically, such as Figure 3 As shown, the method includes:

[0071] By importing construction plans, comprehensive maintenance plans, and operation and dispatch orders, a risk list for key operations is automatically generated. Based on pre-set special train numbers such as military vehicles, inspection vehicles, and return train sets, as well as information on temporary trains and temporary adjustment trains, a risk list for key trains is automatically generated.

[0072] Based on the risk control list of key operations and key trains, and combined with the start and end times, stations, and control content of the risk control items, a risk control map is automatically generated.

[0073] Based on the start time of each risk control item in the risk control diagram, the system automatically reminds the monitor to begin monitoring.

[0074] Once a key operation begins, the status of on-site equipment and the operational status are compared with the predefined standard status in the risk control diagram. If they are inconsistent, an alarm is triggered. When a key train is operating at a station, the actual operating status of the train is compared with the predefined standard operational status in the risk control diagram. If they are inconsistent, an alarm is triggered.

[0075] During key operations or when key trains are in operation, station duty officers receive system prompts and alarms, pay close attention to alarm risk control items, and carry out operations according to standard operating procedures.

[0076] During key operations or key train operations, the command center monitoring personnel will keep a close eye on the station site and provide timely guidance if any improper operations are encountered.

[0077] The system scans the actual equipment status within its jurisdiction in real time and compares it with the predefined normal equipment status. If a fault is detected, an alarm is triggered promptly.

[0078] The system scans the driving operation status within its jurisdiction in real time and compares it with the predefined standard operating status. If any violations or high-risk operations are found, an alarm is triggered immediately.

[0079] When the station duty officer receives an alarm from the system about equipment failure or high-risk operation, he should promptly confirm it and handle it according to the emergency response guidelines.

[0080] When the command center receives alarms from the system about equipment failures or high-risk operations, the monitoring personnel will promptly monitor the station's operations and emergency response processes. If the station encounters a situation that is difficult to handle, they will provide timely assistance and guidance.

[0081] In summary, this invention, through risk identification, scans construction plans and operation diagrams based on predefined rules for identifying key operational risk types and key trains, automatically identifying and generating risk control items. For risk control items identified in advance according to the rules, a risk alert is issued ten minutes before the risk occurs. For risk control items that cannot be identified in advance, real-time risk alerts are issued based on detection rules. Once a risk control item begins, a risk monitoring interface is provided to compare the operation execution status in real time. For abnormal situations, guidance on abnormal emergency response procedures is provided according to the situation category. Data analysis allows for statistical analysis and playback of the number of risk control items, their execution status, and monitoring status.

[0082] Compared with the prior art, the present invention has the following beneficial effects:

[0083] 1. It provides train dispatch safety monitors at train stations with the means to identify risks in advance and monitor train dispatch operations in a planned manner.

[0084] 2. Provides an intuitive risk management diagram for train arrival and departure.

[0085] 3. Real-time comparison and monitoring of risk control items.

[0086] 4. Real-time inspection and alarm of risks in train dispatching operations, such as violations of regulations and equipment malfunctions.

[0087] 5. Provides guidance on emergency response methods after a risk alarm is triggered.

[0088] 6. This system can be deployed in the safety production command center of the train operation section and at the station, and is easy to promote and use.

[0089] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
