[0046] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0047] As shown in Figure 1, this invention provides a control method for a level crossing device, including:

[0048] The railway tracks at the crossing are divided into several track sections;

[0049] Obtain the segment status of each of the plurality of track segments;

[0050] The segment status of each track section is converted into logical variables, and the train travel status in the track at the crossing is determined based on the logical variables.

[0051] The level crossing equipment in the train track is controlled according to the train's travel status.

[0052] In some embodiments of the present invention, a three-point detection method is used to process the relationship between the section status and the train travel status. The level crossing equipment is connected to the axle counting equipment to collect the occupancy status of each section. When connecting the track circuit, the ZPW-2000 type non-insulated track circuit equipment is used. When connected to the axle counting equipment, the design of the axle counting points is shown in Figure 2. Four axle counting points are set at both ends of the level crossing equipment and both ends of the level crossing train track. The points at both ends of the level crossing equipment are D3 and D2, and the points at both ends of the level crossing train track are D1 and D4. Based on these four axle counting points, the level crossing train track is divided into the first track section S1 (D1-D3), the second track section S2 (D3-D2), and the third track section S3 (D2-D4) according to the train travel direction. In the embodiments of the present invention, after the section status of the level crossing train track is collected based on the axle counting, the collected section status also needs to be filtered to reduce the impact of factors such as point faults and poor contact on train detection. The filtering time can be flexibly adjusted according to the requirements. Based on the same principle, in addition to the axle counting method, the train status can also be detected through track circuits.

[0053] Based on the above segment division, and according to the train's occupancy status (logical variable), the occupancy status of the three segments can be expressed using logical variable values. 0 and 1 can represent segment vacancy and segment occupancy, respectively. In some embodiments of the invention, the logical variable value of a segment occupied by the train is recorded as Z, and the segment vacancy is recorded as K. Based on the train's occupancy status of the three segments, eight logical variable values ​​can be obtained: KKK, KKZ, KZK, ZKK, KZZ, ZKZ, ZZK, and ZZZ. Track segments S1-S3 involve three logical variables in the calculation: logical variable 1 (LOG1), logical variable 2 (LOG2), and logical variable 3 (LOG3). The value range of these three variables is the aforementioned eight logical values. In some embodiments of the invention, each variable is updated only when the train is moving, i.e., when the segment status changes, according to the set travel status.

[0054] LOG1 update: S1 segment changes from idle to occupied; LOG2 update: S2 segment remains occupied, and S3 segment changes from idle to occupied; LOG3 update: S2 segment changes from occupied to idle.

[0055] The system uses three logical variables to perform state machine operations, resulting in nine train states: Train Approaching, No Train, Train Passing Through, Train Approach Timeout, Second Approach Awaiting Confirmation, Second Approach Waiting, Second Approach Allowed, Approach Failure, and Illegal Approach. When a train enters the approach section S1 of the level crossing, it enters the Train Approaching state; when it enters the level crossing section S2, it enters the Train Passing Through state; and when it leaves the departure section S3, it enters the No Train state. Train Approach Timeout: If a train fails to pass through the level crossing area within the expected time (10 minutes, configurable), it enters the Train Approach Timeout state. Approach Failure: If the level crossing equipment detects a train passing through the level crossing area but fails to clear the departure section of the level crossing within the expected time (5 minutes, configurable), it enters the Approach Failure state. Illegal Approach: Detecting approach from two directions on the same track (generally due to communication interruption) enters the Illegal Approach state. When a secondary approach occurs, to ensure the safety of trains and pedestrians and to provide the driver with as much information as possible, different warning signals will be issued based on the train's travel status. Therefore, there are three different states for a secondary approach: secondary approach pending confirmation, secondary approach waiting, and secondary approach permitted. After the second train approaches the level crossing, it first enters the secondary approach waiting state. In the secondary approach waiting state, after a confirmation command is issued, the next state is determined based on whether the level crossing section S2 is occupied. If the level crossing section is occupied, it transitions to the secondary approach permitted state; otherwise, it returns to the secondary approach waiting state. Trains can switch between these states.

[0056] In other embodiments of the present invention, the direction of train travel can be determined based on the section into which the train first approaches. If the first approach is S1, the train enters the upward direction; if the first approach is S3, the train enters the downward direction. The secondary approach is somewhat unique, and depending on the status of other lines, it is further divided into three cases: secondary approach when the train is overtaking on the same line, secondary approach when trains are meeting on different lines in the same direction, and secondary approach when trains are meeting on different lines in opposite directions.

[0057] If the first train is passing through or has already passed through the level crossing (the approach section of the level crossing has been cleared, and the level crossing is closed or is opening), and the level crossing equipment detects that another train is again occupying the approach section of the same line in the same direction, then the approach status of the second train is determined to be a secondary approach (chasing) on ​​the same line, as shown in Figure 3. At this time, the control status of the level crossing equipment is that the level crossing barriers are lowered, the level crossing signal is set to prohibition, and the down-direction blocking signal is set to allow. When there is a train approaching on the first line, if the level crossing equipment detects that there is also a train approaching on another line, then the approach status of the second train is determined to be a secondary approach (meeting). Depending on the direction of travel of the second train, it can be divided into a secondary approach in the same direction when meeting on different lines and a secondary approach in opposite directions when meeting on different lines. As shown in Figure 4, when different routes approach each other twice in the same direction, the control crossing equipment status is that the crossing barriers are down, the crossing signal is set to prohibit signal, and the down-direction blocking signal of Line 1 and Line 2 is set to allow signal; as shown in Figure 5, when different routes approach each other twice in opposite directions, the control crossing equipment status is that the crossing barriers are down, the crossing signal is set to prohibit signal, and the down-direction blocking signal of Line 1 and the up-direction blocking signal of Line 2 are set to allow signal.

[0058] Based on the status of all lines, other trains, and the time the section is occupied, the train approach status of the entire level crossing is determined, supporting multiple lines. Based on the level crossing's train approach status, open and close commands are generated. Level crossings are closed during first approach, second approach, and passing phases; opened during idle phases; and configured to open or close during illegal approach, approach timeout, and approach failure phases, as needed. Simultaneously, different audible and visual alarms can be generated based on the level crossing and train status.

[0059] In some embodiments of the present invention, the level crossing equipment and the interlocking system are connected via Ethernet, supporting communication with multiple interlocking systems. The level crossing and the interlocking system are connected via an RJ-45 Ethernet interface through a switch. The communication network is configured with dual-network redundancy (A and B), and data transmission uses the UDP protocol to achieve bidirectional communication. The level crossing equipment can exchange train travel status and level crossing opening / closing status with the interlocking system, and generate statuses such as first approach, second approach (permitted), illegal approach, and no train based on the train status of each line.

[0060] In some embodiments of the present invention, the level crossing equipment is connected to adjacent level crossings via Ethernet, supporting communication with multiple adjacent level crossings. Level crossings are connected to adjacent level crossings via RJ-45 Ethernet interfaces through switches. The communication networks are configured with dual-network redundancy (A and B), and data transmission uses the UDP protocol to achieve bidirectional communication. The level crossing equipment and adjacent level crossings can send train approach status information to each other, generating statuses such as first approach, second approach (permitted), illegal approach, and no train based on the train status of each line, to set the level crossing switch and indicator light status. When multiple adjacent level crossings exist in an area as shown in the figure below, the safety level crossing control system using this method deploys a control host at each level crossing, shares train position detection information, distributes the calculation of regional level crossing safety logic, and coordinates automatic control of each level crossing.

[0061] In some embodiments of the present invention, the relay status is directly acquired from the input and output. The proximity notification relay is normally down (not in a proximity state) and is activated when a train approaches. The proximity notification stop relay is normally activated (not in a proximity state) and is down when a train departs. Based on the train's approach and departure status, and according to the train status of each line, a first approach, second approach (permitted), illegal approach, and no train status are established, and the level crossing's open and closed status is set accordingly.

[0062] In some embodiments of the present invention, the level crossing equipment can also receive manual control commands and control the level crossing equipment or the equipment connected thereto according to the manual control commands.

[0063] In some embodiments of the present invention, a multi-source fusion algorithm can also be configured to simultaneously employ multiple train status detection methods and level crossing control methods based on the actual conditions of the level crossing. For example, a level crossing may be configured with a "axle counting + interlocking" train detection method, which automatically detects the train's running status by collecting section status data through axle counting, and can simultaneously receive train status data sent by interlocking and manual commands. When multiple train statuses are received simultaneously, the configured safety side processing is applied. Similarly, "track circuit + interlocking," "axle counting + adjacent level crossing + proximity notification relay," etc., can be configured to adapt to various application scenarios and needs.

[0064] As shown in Figure 6, the present invention provides a control system for a level crossing device, comprising:

[0065] The configuration information module is used to determine the system's configuration information. The configuration information includes: axle counting control configuration information, interlocking control configuration information, level crossing coordination control configuration information, relay control configuration information, and fusion control configuration information. Among them, the fusion control configuration information is composed of at least two of the following: axle counting control configuration information, interlocking control configuration information, level crossing coordination configuration information, and relay control configuration information.

[0066] The axle counting control module is used to obtain the train travel status in the track of the level crossing based on the axle counting method when the configuration information determined by the configuration information module is axle counting control configuration information, and to control the level crossing equipment according to the train travel status.

[0067] The interlocking control module is used to obtain the train travel status sent by the interlocking system based on the communication between the level crossing equipment and the interlocking equipment when the configuration information determined by the configuration information module is the interlocking control configuration information, and to control the level crossing equipment according to the train travel status.

[0068] The level crossing coordination control module is used to control each of the several level crossing devices to coordinate control when the configuration information determined by the configuration information module is the level crossing coordination control configuration information, based on the train travel status in the train track of each level crossing device.

[0069] The relay control module is used to obtain the train's travel status based on the relay that detects the train's travel status when the configuration information determined by the configuration information module is relay control configuration information, and to control the level crossing equipment according to the train's travel status.

[0070] The fusion control module is used to control the level crossing equipment to detect the train's operating status and control the level crossing equipment when the configuration information determined by the configuration information module is fusion control configuration information.

[0071] In other embodiments of the present invention, the system employs a safety control platform to perform level crossing logic operations, and uses electronic execution units to control level crossing signaling equipment such as handrails, signal lights, and audio equipment, and collect the status of the signaling equipment. Based on the train's running position (axle counting detection, receiving position information from interlocking equipment, and position information from adjacent safe level crossing control systems), it automatically controls the level crossing to close and open. During train operation or in case of a malfunction, corresponding audible and visual signals, alarm information, and prompts will be sent to facilitate system maintenance and repair. Approach indicator lights and direction indicator lights are also configured to indicate the train's approach port and approach direction. Special prompts will be displayed in special circumstances such as secondary approach or approach failure. The system is equipped with various alarm and prompt messages. In case of a malfunction, a timely alarm can be issued in the alarm information bar; after the malfunction is repaired, a timely reminder will be issued in the prompt information bar, and system operation prompts and alarm information will be sent to the maintenance unit.

[0072] In other embodiments of the present invention, the level crossing logic software runs on the UCP safety platform of the level crossing subsystem with a two-out-of-two architecture. Through the UCP platform, it communicates with the axle counter, computer interlocking, adjacent level crossings, manual control panel, input / output subsystem (level crossing protection equipment), ground electronic unit (LEU / transponder), and central maintenance system. Its main functions are to receive train position information (via axle counter, track circuit relays, computer interlocking, and adjacent level crossings), automatically control (or use interlocking manual commands) or manually control (local manual commands from the manual control panel) the opening and closing of level crossings according to the control mode, output level crossing protection equipment drive commands (input / output subsystem) and transponder message information (LEU / transponder), and simultaneously record the level crossing control system operation log (central maintenance system, offline maintenance terminal). When the level crossing control system is operating normally, it follows a three-step cycle of "input - operation - output". The main control unit first needs to process the input information, which includes three types of sources: human-machine interface commands, data collected by the input / output subsystem, and communication data sent by other systems. After summarizing all the input information, the main control unit will perform logical operations according to the level crossing technical rules and generate corresponding operation results. The output processing unit will output the various output results to the corresponding devices. The output information includes four types: fully electronic module drive, human-machine interface representation information, maintenance information, and communication information sent to other systems.

[0073] The beneficial effects of the above technical solution are as follows: This method is compatible with multiple needs and can automatically control the closure and opening of level crossings based on actual conditions and requirements, through train running position detection, axle counting detection, track circuit detection, position information received from interlocking equipment, position information from adjacent safety crossing control systems, and position information from proximity notification relays; it has regional adjacent level crossing group control functions; and it can be equipped with a manual control panel, providing emergency manual control capabilities. The multi-source fusion algorithm provides more comprehensive and safer level crossing control capabilities, and can promptly feed back the collected level crossing status to adjacent level crossings / interlocking systems, adapting to more complex lines.

[0074] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
