Description

Technical Field

[0001] This invention belongs to the field of railway technology, specifically a method for preventing errors in power outages and restorations of railway overhead contact lines. Background Technology

[0002] When electric locomotives or trains enter a power outage zone, it can cause the locomotives and rolling stock to malfunction, and even lead to personal injury or death. Incorrectly routed trains during station power outages are one of the main reasons why electric locomotives or trains enter powerless areas. Power outages come in various forms, categorized by location (station-wide, section-wide, and neighboring station) and by shape (vertical or V-shaped). Some stations have numerous types of power outage cards and complex feeder outage ranges, making it difficult for duty officers to fully grasp the situation. These factors all increase the risk of incorrect route planning for electric locomotives entering power outage zones. Furthermore, with the rapid development of my country's railways and the increasing railway capacity and volume year by year, station duty officers are often burdened with heavy tasks of receiving, dispatching, and shunting trains, inevitably leading to fatigue and frequent instances of incorrect route planning during overhead contact line outages. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for preventing errors in power outages and restorations of railway overhead contact lines.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A method for preventing errors in power outages and restorations of railway overhead contact lines is as follows:

[0006] (S1) The power outage interface of the intermediate station terminal is displayed in series with the three stations: this station, the section, and the left and right adjacent stations.

[0007] (S2) The power outage card range is displayed using the DG track section selection combination.

[0008] The plan determines the power outage range of the cards by selecting and combining DG track sections. The range of any card is composed of various DG track sections. For parts of a DG track section that have phase separation or are not covered, separate distinctions are set.

[0009] (S3) Closed-loop management of mutual control and confirmation between power outage and restoration stations

[0010] A power outage confirmation process is set up between related stations. The power outage registration station acts as the initiating station. When the corresponding power outage card is clicked, a confirmation box pops up on the related station's interface. The related stations verify the card's accuracy and click "confirm" if correct. Once all related stations have confirmed, the corresponding power outage area is indicated by a red light strip, completing the formal power outage. When power is restored, the registration station sends a power restoration request, which is confirmed by the related stations. Once all confirmations are complete, the red light strip disappears, indicating that power has been officially restored. Simultaneously, the power outage and restoration confirmation process is uploaded to the dispatch and command center, where it is displayed in real time.

[0011] (S4) After a power outage, supervise the locking of relevant turnouts and the capping of relevant buttons.

[0012] Real-time monitoring of turnout locking and button capping; warnings and reminders are given for turnouts that should be locked but are not, and buttons that should be capped but are not, until locking and capping are completed. At the same time, the turnout locking and button capping status is displayed in the dispatch and command center.

[0013] (S5) Send an alarm to the power outage area

[0014] When the power outage is completed and a route is being arranged towards the power outage area, an alarm should be triggered in a timely manner to remind the duty officer to take corrective measures. The alarm method is that the red light strip in the power outage area flashes, an alarm box pops up, and a voice alarm appears simultaneously, and is also uploaded to the dispatch and command center at the same time.

[0015] (S6) The intermediate station is connected to the dispatch and command center. The power outage status of each station, the confirmation status of the power outage and restoration process, the status of the lock button on the turnout, and the status of the circuit alarm are displayed synchronously and in real time on the screen of the dispatch and command center. The dispatch and command center personnel can monitor and supervise the power outage and restoration status of each station in the jurisdiction in real time.

[0016] The dispatch and command center can add and delete cards, and can modify the power outage range of a card.

[0017] Furthermore, a railway overhead contact system for preventing power outages and restorations errors includes an intermediate station system, a dispatching and command center system, and a server.

[0018] The intermediate station system is used to acquire the status data of all station equipment and the control data of the duty officer; display the station map, the section map, the left and right adjacent stations, all power outage cards of the station, the power outage and restoration operation process, generate turnout locking and button capping information, and generate alarm information; and simultaneously upload power outage information, power outage and restoration confirmation process, turnout locking and button capping information, and alarm information to the dispatch center system.

[0019] The dispatch and command center system is used to display station maps of the entire section and arrange them in order of line number; to confirm the power outage and restoration process of each station; to display power outage status; to display the lock status of turnouts at intermediate stations; to display the cap status of buttons; to display alarm information at intermediate stations; to modify power outage cards; and to set up associated stations.

[0020] The server is used to record and store each card and its range, power outage information for each station, power outage and restoration processes, turnout locking, button capping information, alarm information, and the communication hub.

[0021] Furthermore, the intermediate station system also includes a data acquisition system for acquiring the status of all station equipment and the operation status of the duty officer. The data acquisition system includes a data collection module and an image recognition module.

[0022] The data acquisition module is used to obtain the status of all station equipment and the operation status of the duty officer by sharing existing signal equipment data;

[0023] The image recognition module is used to identify the operator's button operation, light strip and turnout status, thereby obtaining the status data of all station equipment and the operator's operation.

[0024] Furthermore, the data acquisition module uses serial port acquisition and ensures that the acquired data does not affect the safety of existing signal equipment by setting a data acquisition safety isolation module. The data acquired by the data acquisition module is sent to the power outage host after passing through the safety isolation module. The data acquisition safety isolator module includes a core processing circuit, an optocoupler isolation circuit, an input circuit, an output circuit, and a power supply circuit.

[0025] Furthermore, the image recognition module uses a microcomputer interlocking control panel for recognition. It performs feature calculations and memorizes button flashing, turnout positioning, turnout locking, light strips, and signal lights. Based on the color, brightness, and shape of the target, it calculates and compares to obtain the status of the signal equipment and the operator's operation, and generates data to send to the host.

[0026] Furthermore, the intermediate station system includes a first graphics module, a data acquisition and parsing module, a logic analysis and judgment module, a first communication module, and a first output module;

[0027] The first graphics module is used to draw schematic diagrams of power stations for power outages and to display the diagrams of the power stations being called.

[0028] The data acquisition and parsing module is used to parse the data acquired by the data acquisition module and the image recognition module according to the data protocol, so as to obtain the status of the station equipment and the control data of the duty officer.

[0029] The logic analysis and judgment module is used to generate turnout locking and button capping prompts and generate power outage alarm information based on the parsed station equipment status data and duty officer operation data through logical judgment.

[0030] The first communication module is used to communicate with the server and push information to the server about the duty officer clicking on the card, the lock status of the turnout button, and the alarm status of the power outage area.

[0031] The first output module is used to display the intermediate station's power outage and restoration information, power outage and restoration confirmation information, turnout lock button capping information, light strip flashing alarm, and sound alarm.

[0032] Furthermore, the dispatch and command center system includes a second graphics module, a power outage card setting module, an intermediate station association setting module, a second communication module, and a second output module, wherein...

[0033] The second graphics module is used to draw and display a schematic diagram of the entire power plant shutdown and transmission line.

[0034] The power outage card setting module is used to add or remove power outage cards for the entire section, modify the jurisdiction of power outage cards, and send the data to the server for storage.

[0035] The intermediate station association setting module is used to set the intermediate station to offline when the intermediate station loses network access. The system will automatically confirm and complete the power outage and restoration. When the intermediate station reconnects to the network, it will automatically go online and click the confirmation button according to the original process.

[0036] The second communication module is used to communicate with the server, receive power outage information of each intermediate station, turnout locking button capping information, alarm information sent by the server, and push power outage card modification status and intermediate station association settings to the server and store them.

[0037] The second output module is used to display the power outage status of each intermediate station, the confirmation status of the power outage and restoration process, the status of the turnout locking button being capped, and alarm information.

[0038] Furthermore, the intermediate station system has a network outage mode. In the network outage mode, the intermediate station system operates independently, displays the power outage range, provides real-time monitoring and prompts for locking relevant switches and capping relevant buttons, and sends an alarm to the power outage department.

[0039] Furthermore, both the first output module and the second output module include an alarm module, which includes an audible alarm and a visual alarm.

[0040] Furthermore, the server includes a third communication module, a data relay control module, and a database. The third communication module acts as a communication hub, communicating with various intermediate stations and the dispatch and command center system.

[0041] The data relay control module is used to relay communication with the intermediate station and the dispatch command center system, and determines, based on the stored records in the database, which related stations need to confirm the card to be pushed to the intermediate station or the dispatch command center, the jurisdiction of the power outage card, etc.

[0042] The database is used to store recorded data, including information such as card clicks by the duty officer, confirmation information from the relevant station, official power outage information, incoming call information, card name, the relevant station of the card, the scope of the card, and whether the intermediate station has automatically gone offline due to network outage.

[0043] In this invention, a three-station series connection is adopted, which includes the local station, the section, and the left and right adjacent stations. This three-station series connection display method allows the duty officer to have a good grasp of the power outage status of the local station, the section, and the adjacent stations, and prevents incorrect connection and power generation.

[0044] In this invention, the intermediate station is connected to the dispatch and command center. The power outage status of each station, the confirmation status of the power outage and restoration process, the status of the lock button on the turnout, and the status of the circuit alarm are displayed synchronously and in real time on the large screen of the dispatch and command center. The dispatch and command center personnel can keep abreast of and supervise the power outage and restoration status of each station in the jurisdiction.

[0045] This invention is designed to connect intermediate stations with the dispatch and command center system. The power outage status of each station, the confirmation status of the power outage and restoration process, the status of the lock button on the turnout, and the status of the circuit alarm are displayed synchronously and in real time on the large screen of the dispatch and command center. The dispatch and command center personnel can monitor and supervise the power outage and restoration status of each station in the jurisdiction in real time.

[0046] In summary, the method of this invention is convenient and simple to operate, without increasing the workload of on-site duty personnel; it adopts comprehensive measures and multi-stage control to effectively prevent mishandling; the power outage range is transparent between stations, and power outages at this station, the section, and neighboring stations can all be displayed, making it intuitive and clear; to prevent unfounded power outages, a mutual control and confirmation step between power outages and restorations is added; the network design allows the dispatch and command center to view power outage information, power outage and restoration processes, implementation status of control measures, alarms, etc., at all stations along the entire section in real time. Attached Figure Description

[0047] Figure 1 This is an overall flowchart of the present invention. Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1 This invention further illustrates the specific implementation of a method for preventing power outages and restorations in railway overhead contact lines. The method for preventing power outages and restorations in railway overhead contact lines is not limited to the descriptions in the following embodiments.

[0049] Example 1:

[0050] This embodiment provides a method for preventing errors in power outages and restorations of railway overhead contact lines, such as... Figure 1 As shown, the specific method is as follows:

[0051] (S1) The power outage interface of the intermediate station terminal adopts the three-station series connection method of the station, the section, and the left and right adjacent stations. Since the feeder phase split is usually near the section or the station entrance, if only the power outage range of the station is displayed, it is impossible to grasp the power outage situation of the section and adjacent stations. If there is a power outage in the section or adjacent station, it may cause the train to enter the power outage area due to incorrect dispatch. The three-station series display method allows the duty officer to grasp the power outage situation of the station, the section, and the adjacent stations well, and prevents incorrect connection and dispatch.

[0052] (S2) The power outage card range is displayed using the DG track section selection combination;

[0053] Since preventing entry into the power outage area primarily aims to prevent operators from mistakenly operating interlocking buttons and causing errors, the display of the power outage range on the cards and its integration with interlocking signal equipment and track sections is crucial. Only when operators clearly understand the power outage range and its corresponding sections, switches, signals, and buttons can they avoid erroneous operations. The solution determines that the power outage range of the cards is selected and combined according to DG track sections. Each card's range is composed of various DG track sections. For sections within a DG track section that are separated or not covered, separate settings are used to differentiate them. This way, the power outage range of each card clearly displays which DG track sections are covered, which switches, signals, and buttons are included, etc., providing operators with clear information and significantly reducing the chance of errors.

[0054] (S3) Closed-loop management of mutual control and confirmation between power outage and restoration stations

[0055] To prevent duty officers from assuming power outages or mistakenly clicking on power outage cards, a mutual confirmation process is implemented between related stations. The power outage registration station initiates the process by clicking on the corresponding power outage card. A confirmation box pops up on the interface of the related stations, who verify the card's accuracy and click confirm if correct. Once all related stations have confirmed, the corresponding power outage area is indicated by a red light, signifying a formal power outage. When power is restored, the registration station sends a power restoration request, which is confirmed by the related stations. Once all confirmations are complete, the red light disappears, indicating that power has been officially restored.

[0056] (S4) After a power outage, supervise the locking of relevant turnouts and the capping of relevant buttons;

[0057] Real-time monitoring of turnout locking and button capping; warnings and reminders are given for turnouts that should be locked but are not, and buttons that should be capped but are not, until locking and capping are completed. At the same time, the turnout locking and button capping status is displayed in the dispatch and command center.

[0058] (S5) Send an alarm to the power outage area;

[0059] When the power outage is completed and a route is being arranged towards the power outage area, an alarm should be triggered in a timely manner to remind the duty officer to take corrective measures. The alarm method is that the red light strip in the power outage area flashes, an alarm box pops up, and a voice alarm appears simultaneously, and is also uploaded to the dispatch and command center at the same time.

[0060] (S6) The intermediate station is connected to the dispatch and command center. The power outage status of each station, the confirmation status of the power outage and restoration process, the status of the lock button on the turnout, and the status of the circuit alarm are displayed synchronously and in real time on the screen of the dispatch and command center. The dispatch and command center personnel can monitor and supervise the power outage and restoration status of each station in the jurisdiction in real time.

[0061] The dispatch and command center can add and delete cards, and modify the power outage range of cards. The permissions for adding, deleting, and modifying the range of cards are set in the dispatch and command center.

[0062] In this embodiment, the data collected by each intermediate station is acquired via serial port. A data acquisition safety isolation module is set up to ensure that the acquired data does not affect the safety of existing signal equipment. The data acquired by the acquisition module is sent to the power outage host after passing through the safety isolation module. The data acquisition safety isolator module includes a core processing circuit, an optocoupler isolation circuit, an input circuit, an output circuit, and a power supply circuit. The optocoupler isolation circuit adopts high-impedance optical isolation technology and uses military-grade chips to ensure physical isolation between the data acquisition device and the existing equipment circuits, minimizing electromagnetic interference and impact on the existing equipment. The input circuit adopts multiple data interfaces, which can acquire RS232, RS485, RS422, CAN bus, and other interface data. After processing by the core processing chip, the useful switch data is converted into RS232 data and output to the host. When sending RS232 data to the host, only the TX and GND lines are connected, that is, only sending and not receiving, which is unidirectional communication and can better protect the equipment from being affected. The entire data acquisition module has no network interface and no network security risk.

[0063] In this embodiment, the image recognition of each intermediate station adopts microcomputer interlocking control panel recognition. It performs feature calculation and memory on buttons and button flashing, turnout positioning, turnout locking, light strips, and signal lights. It calculates and compares the target's pigment, brightness, and shape to obtain the status of signal equipment and the operator's operation. The generated data is sent to the host. Since the camera inevitably vibrates and the captured image has displacement deviation, the program is designed with an automatic calibration function. The feature calculation mainly uses the following methods: In feature extraction, the basic method is to detect corners, edges, and regions based on pixel gradient changes, such as first and second derivatives and geometric features. Edges are the locations where the image brightness changes discontinuously or abruptly, and corners are the locations where the edge discontinuities or abrupt changes occur, that is, the places where the curvature of the edge curve is maximized.

[0064] Example 2:

[0065] A method for preventing errors in power outages and restorations of railway overhead contact lines includes an intermediate station system, a dispatching and command center system, and a server.

[0066] The intermediate station system is used to acquire the status data of all station equipment and the control data of the duty officer; display the station map, the section map, the left and right adjacent stations, all power outage cards of the station, the power outage and restoration operation process, generate turnout locking and button capping information, and generate alarm information; and simultaneously upload power outage information, power outage and restoration confirmation process, turnout locking and button capping information, and alarm information to the dispatch center system.

[0067] The dispatch and command center system is used to display station and yard maps of the entire section, arranged in order of line type; to confirm the power outage and restoration process of each station; to display power outage status; to display the lock status of turnouts at intermediate stations; to display the status of button caps; to display alarm information at intermediate stations; to modify power outage cards; and to set up associated stations.

[0068] The server is used to record and store each card and its range, power outage information for each station, power outage and restoration processes, turnout locking, button capping information, alarm information, and the communication hub.

[0069] The intermediate station system also includes a data acquisition system, used to acquire the status of all station equipment and the operation status of the duty officers. The data acquisition system includes a data collection module and an image recognition module.

[0070] The data acquisition module is used to obtain the status of all station equipment and the operation status of the duty officer by sharing existing signal equipment data;

[0071] The image recognition module is used to identify the operator's button operation, light strip and turnout status, thereby obtaining the status data of all station equipment and the operator's operation.

[0072] The data acquisition module uses serial port acquisition and ensures that the acquired data does not affect the safety of existing signal equipment by setting a data acquisition safety isolation module. The data acquired by the data acquisition module is sent to the power outage host after passing through the safety isolation module. The data acquisition safety isolator module includes core processing circuit, optocoupler isolation circuit, input circuit, output circuit and power supply circuit.

[0073] The image recognition module uses a microcomputer interlocking control panel for recognition. It performs feature calculations and memorizes buttons and button flashing, turnout positioning, turnout locking, light strips, and signal lights. Based on the color, brightness, and shape of the target, it calculates and compares to obtain the status of the signal equipment and the operator's operation, and generates data to send to the host.

[0074] The intermediate station system includes a first graphics module, a data acquisition and parsing module, a logic analysis and judgment module, a first communication module, and a first output module;

[0075] The first graphics module is used to draw schematic diagrams of power stations for power outages and to display the diagrams of power stations to be called.

[0076] The data acquisition and parsing module is used to parse the data acquired by the data acquisition module and the image recognition module according to the data protocol, so as to obtain the status of the station equipment and the control data of the duty officer.

[0077] The logic analysis and judgment module is used to generate turnout locking and button capping prompts and generate power outage alarm information based on the parsed station equipment status data and duty officer operation data.

[0078] The first communication module is used to communicate with the server and push information to the server about the duty officer clicking on the card, the lock status of the turnout button, and the alarm status of the power outage area.

[0079] The first output module is used to display information on power outages and restorations at intermediate stations, confirmation information on power outages and restorations, information on turnout locking buttons being capped, light strip flashing alarms, and sound alarms.

[0080] The dispatch and command center system includes a second graphics module, a power outage card setting module, an intermediate station association setting module, a second communication module, and a second output module.

[0081] The second graphics module is used to draw and display a schematic diagram of the power stations along the entire section.

[0082] The power outage card setting module is used to add or remove power outage cards for the entire section, modify the jurisdiction of power outage cards, and send the data to the server for storage.

[0083] The intermediate station association setting module is used to set the intermediate station to offline when the intermediate station loses network access. The system will automatically confirm and complete the power outage and restoration. When the intermediate station reconnects to the network, it will automatically go online and click the confirmation button according to the original process.

[0084] The second communication module is used to communicate with the server, receive power outage information of each intermediate station, turnout locking button capping information, alarm information sent by the server, and push and store power outage card modification information and intermediate station association settings to the server.

[0085] The second output module is used to display the power outage status of each intermediate station, the confirmation status of the power outage and restoration process, the status of the turnout locking button being capped, and alarm information.

[0086] The intermediate station system has a network outage mode. In the network outage mode, the intermediate station system operates independently, displays the power outage range, provides real-time monitoring and prompts for locking relevant switches and capping relevant buttons, and sends alarms to the power outage area.

[0087] Both the first output module and the second output module include an alarm module, which includes both audible and visual alarms.

[0088] The server includes a third communication module, a data relay control module, and a database. The third communication module acts as a communication hub, communicating with various intermediate stations and the dispatch and command center system.

[0089] The data relay control module is used to relay communication with the intermediate station and the dispatch and command center system. Based on the stored records in the database, it determines which related stations need to confirm the card before it can be pushed to the intermediate station or the dispatch and command center, as well as the jurisdiction of the power outage card.

[0090] The database is used to store recorded data, including information such as the duty officer clicking on the card, confirmation information from the related station, official power outage information, incoming call information, card name, the related station of the card, the scope of the card, and whether the intermediate station has automatically gone offline due to network outage.

[0091] By adopting the above technical solution:

[0092] Since feeder phase splits are usually located near the section or the station entrance, if only the power outage range of the station is displayed, it is impossible to grasp the power outage situation of the section and adjacent stations. If there is a power outage in the section or adjacent station, it may cause the train to enter the power outage area due to incorrect dispatch. In this invention, a three-station series display method is adopted, which displays the station, the section, and the left and right adjacent stations. The three-station series display method allows the duty officer to grasp the power outage situation of the station, the section, and the adjacent stations, and prevents incorrect connection and dispatch.

[0093] Since the primary goal of preventing entry into the power outage area is to prevent operators from mistakenly operating interlocking buttons and causing errors, the display of the power outage range on the cards and its integration with interlocking signal equipment and track sections is crucial. Only when operators clearly understand the power outage range and its corresponding sections, switches, signals, and buttons can they avoid erroneous operations. Therefore, the scheme determines that the power outage range of the cards is selected and combined according to DG track sections. Each card's range is composed of various DG track sections. For parts within a DG track section that are phase-separated or not covered, separate distinctions are made. In this way, the power outage range of each card clearly displays which DG track sections are covered, which switches, signals, and buttons are included, etc., providing operators with clear information and greatly reducing the probability of errors.

[0094] The system employs a closed-loop management system for mutual control and confirmation among power outage and restoration stations, where one power outage card is associated with several intermediate stations. To prevent duty personnel from assuming power outages or mistakenly clicking on power outage cards, the system includes a mutual confirmation process among power outage stations. The power outage registration station initiates the process by clicking the corresponding power outage card. A confirmation box pops up on the interface of each related station, which verifies the card's accuracy. If correct, the station clicks "confirm." Once all related stations have confirmed, the corresponding power outage area is indicated by a red light, signifying a formal power outage. When power is restored, the registration station sends a power restoration request, which is confirmed by the related stations. Once all confirmations are complete, the red light disappears, indicating that power has been officially restored.

[0095] After a power outage, monitor the locking of relevant turnouts and the capping of relevant buttons. Due to the control measures required after a power outage, relevant turnouts must be locked and relevant buttons capped. This must be monitored in real time. For turnouts that should be locked but are not, and buttons that should be capped but are not, issue warnings and reminders until locking and capping are completed. The lockout and capping status of turnouts is displayed synchronously in the dispatch and command center.

[0096] This invention provides an alarm for routing routes to the power outage area. When a power outage is completed and a route is being routed to the power outage area, an alarm is triggered in a timely manner to remind the duty officer to take corrective measures in time to prevent errors. The alarm is triggered by three simultaneous methods: a flashing red light in the power outage area, a pop-up alarm box, and a voice alarm, all of which are simultaneously uploaded to the dispatch and command center.

[0097] This invention features a network design connecting intermediate stations with the dispatch and command center. The power outage status of each station, the confirmation status of the power outage and restoration process, the status of the switch locking button, and the status of the circuit alarm are displayed synchronously and in real time on the large screen of the dispatch and command center. The dispatch and command center personnel can monitor and supervise the power outage and restoration status of each station in real time.

[0098] This invention allows for the addition and deletion of cards, and the modification of the power outage range for each card, all through a dispatch and command center. The authority to add, remove, and modify the range of cards is set at the dispatch and command center.

[0099] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
