Description

Technical Field

[0001] The invention relates to the field of intelligent control technology, and in particular to an integrated system of full electronic interlocking and crossing centralized control. Background Art

[0002] Most railway stations have areas where railways and roads intersect on the same plane. This area is called a railway level crossing (referred to as a railway crossing). It is the only area in the railway transportation network where there is a right of way conflict with the road. It is relatively important and special in railway transportation. This area is prone to accidents, and once an accident occurs, it directly threatens people's lives and safety, and may even cause large-scale serious accidents, affecting normal railway transportation. At present, most railway stations with crossings have station interlocking systems and crossing control systems.

[0003] The main functions of the station interlocking system include ensuring the safety of train driving and shunting operations, improving operating efficiency and reducing labor intensity. The interlocking system uses technical means to establish a mutually restrictive relationship between signals, switches and routes to ensure the safe operation of trains on the routes. Specifically, the interlocking system ensures that the routes are free, the switches are in the correct position and there are no hostile routes. Only when these conditions are met will the signal be opened to allow the train to enter.

[0004] The main function of the crossing control system is to prevent municipal road vehicles and pedestrians from entering the railway track and colliding with passing trains, thereby ensuring the normal operation safety of trains and the safety of road users; the crossing control system is divided into two types: manned and unmanned; the manned crossing control system is equipped with professional crossing operators who are responsible for monitoring and operating the railway crossing equipment to realize the opening / closing of the railway crossing. For example: when the train dispatcher calls the crossing operator in advance or the train approaches the crossing alarm reminder area, the crossing operator manually controls the barrier machine to descend and turns on the sound and light alarm. When the train passes through the railway crossing, the crossing operator manually controls the barrier machine to rise and turns off the sound and light alarm. Unmanned crossings do not require manual intervention, and only realize the sound and light alarm reminder of the railway crossing. It cannot effectively prevent municipal road vehicles and pedestrians from forcibly passing through the crossing. For stations with a large number of manned crossings, a large number of professional crossing operators need to be equipped for duty, and a large number of crossing control rooms need to be built, which increases the construction cost and personnel management cost; for crossings at remote stations, the passage safety and working environment of the crossing operators need to be effectively guaranteed.

[0005] In order to reduce the labor intensity of crossing operators, some crossing control systems now collect train approach notifications by adding axle counting equipment or high-frequency track circuits on the track, and some crossing control systems collect train approach notification information from the station interlocking system. The crossing control system automatically controls the crossing equipment according to the collected train approach notification information, such as the operation of the crossing barrier machine and the lighting of the crossing blocking signal.

[0006] Some level crossing control systems are equipped with surveillance cameras to provide signal operators with level crossing video surveillance. However, the level crossing video window cannot be automatically linked to the train position. Signal operators need to look for the level crossing video screen on the large screen, which increases the workload of signal operators.

[0007] The existing crossing control system is independent of the interlocking system. When a crossing equipment fails, the interlocking system cannot provide feedback. For example, the crossing blocking signal is controlled by the crossing control system. When the blocking signal fails, the blocking signal status cannot be fed back to the signal operator in time, and the driver cannot be guided in time. When the driver finds that the blocking signal is off, the driver will stop in front of the blocking signal, thereby affecting the traffic efficiency of the train at the crossing. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide an integrated system of fully electronic interlocking and centralized crossing control, which reduces engineering construction costs and personnel management, improves the working environment of on-duty personnel, reduces the safety risks when trains pass through crossings, and improves crossing traffic efficiency.

When an abnormal situation is found in the crossing area, the signal operator can take intervention measures such as remote voice reminders and remote manual control of the crossing equipment; when the crossing's blocking signal fails, this solution can be supervised through the full electronic interlocking crossing integrated system, thereby strengthening the blocking signal state supervision function and improving the crossing's traffic efficiency.

[0044] Since the current applications of the centralized control system and the all-electronic interlocking system for crossings are independent, this solution integrates the functions of the centralized control system for crossings into the all-electronic interlocking system, which greatly reduces the construction cost of the system. After the crossing equipment is automatically controlled, the workload of manual control at the crossing is greatly reduced and the working environment of the operators is improved. Signal operators and crossing operators can be centrally managed, and the management process can be optimized, thereby reducing operating costs.

[0054] The human-machine interaction layer is used to send instructions to the interlocking control layer and receive and display the status of outdoor equipment. The human-machine interaction layer includes a host computer, a maintenance machine, a video controller and an integrated display screen for interlocking crossings;

[0055] The logic operation layer is connected to the human-computer interaction layer, and is used to perform interlocking logic operations according to the received instructions and the status of the outdoor equipment, and output control instructions to the drive acquisition layer. The logic operation layer includes an interlocking machine, an IO communication module, and a relational database;

[0056] The drive collection layer is connected to the logic operation layer, and is used to receive control instructions and drive outdoor devices, and collect the status of outdoor devices and feed it back to the logic operation layer. The drive collection layer includes multiple IO modules;

[0057] The outdoor equipment layer includes a crossing control box, station signal equipment, crossing equipment and video monitoring equipment. The outdoor equipment layer is connected to the drive collection layer through a signal cable or an optical cable.

[0058] In the embodiment of the present invention, through interlocking logic operation, the system can ensure the safety of various operations in the process of controlling railway crossing and station signal equipment. Any operation that may cause danger will be automatically locked by the system, thereby greatly reducing the safety risks caused by human errors. The system adopts a multi-level architecture design, and data transmission and instruction issuance are carried out through stable communication connections between each level. This design not only ensures the accuracy of data transmission, but also improves the operational reliability of the entire system. The fully electronic interlocking control and centralized management of crossings achieve rapid response and efficient processing. Compared with traditional manual or semi-automatic control systems, this integrated system significantly reduces the operation time and improves the traffic efficiency of crossings and stations. The modular design of the system makes each component relatively independent, which is convenient for troubleshooting and maintenance. At the same time, the setting of the maintenance machine and video controller enables maintenance personnel to remotely monitor and debug the system, further reducing maintenance costs. The design of the human-computer interaction layer fully considers the actual needs of the operator. Through the intuitive interface provided by the host computer, the operator can easily send instructions and view the status of outdoor equipment in real time. This user-friendly design greatly improves the operating experience.

[0059] In the embodiment of the present invention, the human-computer interaction layer includes a host computer, a maintenance machine, a video controller and an integrated display screen for interlocking crossings;

[0060] The upper computer is used by the signal operator to send the instructions of arranging the route, single-operating the turnout and the column machine to the interlocking control layer; send the instruction of canceling the route when there is a plan change, send the instruction of manual unlocking and section fault unlocking when there is a route unlocking failure; when the outdoor signal equipment or crossing equipment failure is collected, the sound and light alarm is issued to prompt the signal operator to pay attention to and assist in handling the failure;

[0061] The maintenance machine is used to store historical status data of station equipment and crossing equipment, historical data of manual operation instructions, and historical data of fault alarms, and to perform statistical analysis and playback on the historical data, so as to enable the electrical maintenance personnel to find and analyze the cause of the fault;

[0062] The video controller is used to display the camera image of the road crossing in real time, so that the signal operator can understand the situation of the road crossing on site. When encountering danger, the signal operator can remotely control the road crossing equipment through the host computer according to the video display content;

[0063] The interlocking crossing integrated display large screen is used to integrate the station interlocking interface with the crossing video display. When a train approaches a certain crossing, the video screen is switched to the corresponding crossing in advance, and the signal operator monitors the actual situation of the crossing barrier, passers-by and municipal vehicles in the crossing area in real time.

[0064] In the embodiment of the present invention, through the host computer, the signal operator can conveniently send various instructions to the interlocking control layer, such as arranging routes, single-operating turnouts, and column machine lifting and lowering. This intuitive and centralized operation method not only simplifies the operation process, but also improves the accuracy of the operation, thereby ensuring the safe and efficient operation of railway crossing and station signal equipment. The host computer has real-time fault monitoring and sound and light alarm functions. Once the outdoor signal equipment or crossing equipment failure is collected, it can immediately remind the signal operator to pay attention and assist in handling. At the same time, the maintenance machine can save a large amount of historical data, including equipment status, manual operation instructions and fault alarms, etc., providing powerful data support for electrical maintenance personnel, facilitating them to find and analyze the cause of the fault, and then take effective preventive measures. The introduction of video controllers and video display large screens enables signal operators to grasp the on-site crossing situation in real time. In the event of danger or emergency, the operator can quickly make judgments based on the video display content and remotely control the crossing equipment through the host computer to ensure the safety of the crossing. In addition, when the train approaches a certain crossing, the system can automatically switch the video screen to the corresponding crossing, providing a more convenient monitoring method for signal operators. The integrated display screen of the interlocking crossing realizes the display fusion of the station interlocking interface and the crossing video, providing a comprehensive and intuitive monitoring platform for signal operators. This design not only improves the display efficiency and accuracy of information, but also enables operators to focus on multiple key information points on the same interface at the same time, so as to make more comprehensive and accurate decisions.

[0065] In an embodiment of the present invention, the logic operation layer includes an interlocking machine, an IO communication module and a relational database;

[0066] The interlocking machine is used to perform interlocking logic operations in real time according to the control instructions received from the upper computer of the human-machine interaction layer and the outdoor device status collected from each IO module of the drive collection layer, and output the outdoor device control instructions to the IO module;

[0067] The instructions received by the interlocking machine from the host computer include arranging the route, fixed switch operation, reverse switch operation, single switch release, single switch lock, establishing the general locking of the guide, opening the guide signal, canceling the route, canceling the general locking of the guide, manually unlocking the route, unlocking the section fault, unlocking the ramp, raising and lowering the column machine, etc.

[0068] The instructions output by the interlocking machine to the signal module include signal machine drive instructions, turnout drive instructions, scattered drive instructions, and crossing drive instructions; the interlocking machine sends the outdoor equipment status collected from each IO module of the drive acquisition layer to the host computer of the human-machine interaction layer in real time; the interlocking machine sends the outdoor equipment status collected from each IO module of the drive acquisition layer, the control instructions sent by the host computer, the status data of the IO module, and the system alarm data to the maintenance machine of the human-machine interaction layer in real time, so that the power supply personnel can maintain and check and analyze the cause of the fault; the IO communication module is used to control each IO module of the drive acquisition layer in multiple ways; the relational database is used to store the historical data generated by the system of this solution, and the historical data is stored by the maintenance machine of the user interaction layer.

[0069] In the embodiment of the present invention, the interlocking machine, as the core of the logic operation layer, can quickly and accurately perform interlocking logic operations according to the control instructions of the host computer and the outdoor equipment status collected by the IO module. This efficient and real-time computing capability ensures the rapid response and precise control of the railway crossing and station signal equipment, thereby improving the operating efficiency and safety of the entire system. The interlocking machine can receive and process a variety of control instructions from the host computer, such as arranging routes, turnout operations, and opening of guide signals, which enables the system to flexibly respond to various complex operating requirements. At the same time, the interlocking machine can also output a variety of control instructions to the signal module to achieve precise control of the outdoor equipment. The interlocking machine not only collects the status of the outdoor equipment in real time, but also feeds back this status information to the host computer and the maintenance machine in a timely manner. This provides valuable data support for signal operators and electrical maintenance personnel, enabling them to grasp the operating status of the equipment at any time, and to discover and deal with potential problems in a timely manner. The design of the relational database enables the system to store historical data for a long time, including equipment status, control instructions, IO module status, and system alarm data. These data can not only be viewed by electrical maintenance personnel at any time to understand the historical operation of the equipment, but can also be used for in-depth analysis of the cause of the fault and the formulation of preventive measures. The design of the IO communication module enables the logic operation layer to communicate efficiently with each IO module of the drive acquisition layer. This multi-channel control method not only improves the flexibility and reliability of communication, but also ensures the precise control of outdoor equipment.

[0070] In the embodiment of the present invention, the drive acquisition layer is composed of various IO modules, including: a turnout module, a signal module, a track module, a scattered module and a crossing control module;

[0071] Each IO module of the drive acquisition layer receives the control command sent by the interlocking machine from the IO communication module of the interlocking logic layer and converts the command into an electrical signal and outputs it to the corresponding node of the distribution board through the IO cable, thereby driving the corresponding outdoor equipment; the status of the outdoor equipment is collected back to the corresponding node of the distribution board through the signal cable, so that the input node of the IO module collects the status of the outdoor equipment from the distribution board via the IO cable;

[0072] The IO module is connected to the distribution board through the IO cable, and then the signal cable from the distribution board controls the action of the outdoor equipment and collects the status of the equipment; the functions of each IO module are as follows:

[0073] Turnout module: used to drive the turnout machine and collect the position information of the turnout machine.

[0074] Signal module: used to drive the signal lights and collect the status of the signal light filament.

[0075] Track module: used to collect the occupied or idle status of the track circuit.

[0076] Scattered module: used to drive scattered circuit actions and collect scattered circuit status.

[0077] Crossing control module: used to drive the operation of crossing equipment and collect the status of crossing equipment.

[0078] In an embodiment of the present invention, by subdividing the drive acquisition layer into independent IO modules such as turnout module, signal module, track module, scattered module and crossing control module, the system achieves a high degree of modularization. This design not only simplifies the complexity of the system, but also improves the independence and reliability of each module. Each module can be troubleshooted and repaired separately, thereby reducing the maintenance difficulty and cost of the overall system. Each IO module can accurately receive the control commands sent by the interlocking machine, and convert these commands into electrical signals and output them to the nodes corresponding to the distribution board, thereby realizing the precise drive of outdoor equipment. This design ensures the accuracy and timeliness of equipment action and improves the control accuracy and response speed of the entire system. The IO module can collect the status information of outdoor equipment in real time, and transmit this information back to the distribution board and interlocking machine through the signal cable. This provides the system with real-time equipment status feedback, so that operators and maintenance personnel can grasp the actual operation of the equipment at any time, and promptly discover and deal with potential problems. Due to the modular design, the drive acquisition layer can be easily expanded and upgraded as needed. When new equipment or functions need to be added, only the corresponding IO module needs to be added. At the same time, the independence of each module also makes maintenance more convenient, and specific modules can be repaired and replaced separately. The design of special modules such as turnout modules and signal modules enables the system to optimize the drive and control of different types of outdoor equipment. For example, the turnout module can accurately drive the turnout machine and collect its position information, while the signal module can accurately control the lighting of the signal machine and monitor the filament status. This design improves the system's adaptability and control performance for different equipment, thereby improving the operating efficiency and safety of the entire system.

[0079] In an embodiment of the present invention, the outdoor equipment layer includes:

[0080] The crossing control box is used to store the photoelectric conversion module, crossing control module and other equipment that assist in crossing control for controlling outdoor crossing equipment. The photoelectric conversion module is used to convert optical signals and electrical signals.

The semi-automatic blocking is used to control the train to run at a certain distance interval through signals.

[0081] In an embodiment of the present invention, the photoelectric conversion module in the crossing control box can efficiently convert optical signals into electrical signals, or convert electrical signals into optical signals. This conversion function makes data transmission more stable and efficient, and can adapt to the transmission requirements in different environments, thereby ensuring the accurate transmission of control instructions and status information. As a centralized control center, the crossing control box can store and manage various modules and equipment required to control outdoor crossing equipment. This design simplifies the wiring and management complexity of the system and improves the overall reliability and maintainability of the system. The crossing control module can quickly receive and process the drive instructions from the interlocking machine, and then accurately control the outdoor crossing equipment and the interlocking station signal equipment, such as signal machines, turnouts, track circuits / axle counting equipment, etc. The design of the crossing control box takes into account future expansion needs, and modules can be easily added or replaced to adapt to changes or upgrades in system functions. At the same time, its flexibility also enables the system to adapt to the needs of different scenarios and configurations. Centralized control of outdoor equipment through the crossing control box can reduce the impact of human operating errors and external interference on system security. In addition, the equipment in the control box can be encrypted and protected to further enhance the security of the system.

These devices can send warning information to the passers-by and vehicles in time, guide them to pass through the crossing correctly and safely, thereby effectively reducing the occurrence of crossing accidents and improving the safety of the crossing. Through video monitoring equipment, including network switches and cameras, the actual situation of the crossing area can be monitored in real time. This real-time monitoring not only helps the signal operator to grasp the dynamics of the crossing at any time, but also provides strong support for remote management. In an emergency, the operator can respond quickly and ensure safety by remotely controlling the crossing equipment. The crossing equipment is connected to the IO communication module interface through an optical cable, realizing efficient data transmission and communication. This connection method not only ensures the speed and stability of data transmission, but also improves the anti-interference ability of the system and ensures the accurate transmission of control instructions and status information. The crossing equipment and video monitoring equipment are centrally placed in the crossing control box. This centralized management method simplifies the wiring and maintenance of the equipment. At the same time, through the connection of the network switch and the LAN optical switch, remote monitoring and management of the equipment is realized, further improving the convenience of maintenance. These configurations of the outdoor equipment layer work closely with other layers of the entire system to improve the overall efficiency of the system. From signal acquisition, interlocking control to device drive and video monitoring, each link has achieved efficient collaborative work, thus ensuring the stable operation and efficient management of the entire system.

[0085] In an embodiment of the present invention, when a train approaches a crossing alarm area, a fully electronic interlocking system automatically controls the raising, lowering, stopping, total raising, total lowering, total stopping and emergency closing of the barrier machine; collects the status of the crossing signal and the blocking signal; and displays and alarms through the host computer when the crossing signal and the blocking signal fail.

[0086] In the embodiment of the present invention, the system can automatically and accurately control a series of actions of the barrier machine such as raising, lowering, stopping, etc. according to the approaching situation of the train, as well as advanced functions such as total raising, total lowering, total stopping and emergency closing. This highly automated control method greatly reduces the intervention of human operation, thereby reducing the possibility of operational errors and improving the accuracy and efficiency of the crossing management. The system collects the status information of the crossing signal and the interlocking signal in real time, so that the signal operator can grasp the current status of these key equipment at any time. This real-time status monitoring function provides strong data support for timely discovery and handling of potential problems. When the crossing signal and the interlocking signal fail, the system can display and alarm through the host computer and notify relevant personnel to handle them in time. This fault detection and alarm mechanism greatly shortens the time for fault discovery and handling, and improves the reliability and safety of the system. Through precise automated control and real-time status monitoring, the system can ensure that the crossing responds quickly and accurately when the train approaches, thereby reducing unnecessary delays and waiting time and improving the traffic efficiency of the crossing. These functions of the full electronic interlocking system work together to improve the overall safety of crossing management. By reducing human operating errors, promptly detecting and handling faults, and ensuring accurate operation of crossing equipment, the system effectively reduces the risk of crossing accidents and ensures the safety of trains and passers-by.

[0087] In an embodiment of the present invention, when a train arrives at a predetermined area, the crossing video surveillance will automatically switch to the area that the train is about to pass through, and the signal operator will monitor in real time the municipal road vehicles and pedestrians that the train is about to pass through the crossing, and monitor in real time the movement of the crossing barrier; when a train is about to pass through a multi-crossing area, the surveillance video will automatically switch to the corresponding areas of the multiple crossings that the train is about to pass through according to the train route and the current position of the train, forming a crossing video band, and the signal operator observes the traffic conditions of each crossing through the crossing video band.

[0088] In an embodiment of the present invention, the system can automatically switch the monitoring video to the area where the train is about to pass, providing the signal operator with real-time, high-definition video images of the crossing. This enables the operator to timely discover and monitor the municipal road vehicles and pedestrians that the train is about to pass through the crossing, as well as the action of the crossing barrier, so as to give early warning and take necessary measures to ensure the safe passage of the train. When the train is about to pass through a multi-crossing area, the system can intelligently and automatically switch the monitoring video to the corresponding areas of the multiple crossings that the train is about to pass through according to the train route and current position, forming a crossing video band. This efficient video switching mechanism ensures that the signal operator can continuously and seamlessly observe the traffic conditions of each crossing, improving the monitoring efficiency and accuracy. Through real-time video monitoring, the signal operator can detect abnormal situations at the first time, such as congestion at the crossing, pedestrian intrusion, etc., and quickly take corresponding emergency disposal measures, such as remote control of the barrier, activation of the alarm device, etc., so as to minimize potential safety risks. The automatic switching function of the crossing video monitoring system enables monitoring resources to be more reasonably allocated to each crossing, avoiding waste of resources and unnecessary repeated monitoring. At the same time, through centralized management and remote monitoring, the system also realizes remote maintenance and management of the crossing equipment, reducing operating costs. The close cooperation between the crossing video monitoring system and the full electronic interlocking system has jointly improved the reliability of the entire system. Through the real-time data and information provided by video monitoring, the full electronic interlocking system can more accurately judge the crossing status and control the operation of the equipment, thereby ensuring the safety of trains and crossings.

[0089] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
