Description

Technical Field

[0001] This invention relates to the field of environmental control technology for rail transit tunnels, and in particular to an intelligent environmental control method and system for rail transit tunnels. Background Technology

[0002] In rail transit systems such as subways and urban rail transit, tunnels are critical areas for train operation. When a train stops in a tunnel, tunnel ventilation fans must be activated for forced ventilation to ensure passenger safety and the normal operation of equipment. Existing tunnel ventilation fan control methods mainly include: (1) Timed control: After the train enters the tunnel, the fan runs according to a preset time. This method cannot adapt to the actual stopping time of the train, which may result in energy waste or insufficient ventilation.

[0003] (2) Simple sensor triggering: such as starting the fan after detecting the train's occupation by the axle counting device. This method cannot distinguish whether the train is passing normally or stopping abnormally, nor can it handle complex situations such as multiple trains and parking positions in the tunnel.

[0004] (3) Manual remote control: The wind turbine is started manually by the dispatcher based on experience. This method is slow to respond, relies on personnel experience, and is prone to errors.

[0005] The aforementioned tunnel ventilation control method relies on simple timers or manual judgment to start and stop the tunnel ventilation. It is not deeply integrated with the core safety logic such as the movement authorization calculation and interlocking route control of the signal system. This results in the inability to ensure timely and accurate response of the ventilation system under complex conditions such as multiple trains in the tunnel or trains stopping in the critical protection area of ​​the ventilation, which poses significant safety hazards.

[0006] In view of this, there is an urgent need to provide an intelligent environmental control method for rail transit tunnels to solve the problems of systemic deficiencies and low level of intelligence in the existing ventilation and safety protection of rail transit tunnels. Summary of the Invention

[0007] To overcome the problems existing in related technologies, this disclosure provides an intelligent environmental control method and system for rail transit tunnels, in order to solve the problems of systematic deficiencies and low levels of intelligence in the existing ventilation and safety protection of rail transit tunnels.

[0008] This specification provides one or more embodiments of an intelligent environmental control method for rail transit tunnels, comprising the following steps: During train operation, the onboard controller determines the authorized stopping point to the boundary of the pre-configured ventilation system protection zone; Through interlocking logic configuration, the interlocking system controls a single train to enter the tunnel based on the train status information. When the train reaches the stopping point, if the train's zero-speed state duration exceeds the preset stopping time, the tunnel ventilation system is controlled to deliver air to the direction of the train's route based on the train's route direction. Furthermore, if the train's starting and moving time exceeds the preset running time or the train moves away from the preset distance of the ventilation system, the ventilation system stops operating.

[0009] Furthermore, the specific configuration steps for the ventilation system protection zone are as follows: By pre-configuring the protection range of the ventilation system in the electronic map of the on-board controller, the train can be located in real time and its movement authorization can be calculated. The train's stopping point can be controlled to fall outside the protection area based on the protection area of ​​the ventilation system.

[0010] Furthermore, the specific steps for controlling a single train to enter the tunnel based on train status information using the interlocking system are as follows: By configuring the interlocking table, the occupancy status of the tunnel area is used as the interlocking condition for route processing. If the status is occupied, the relevant signals are prohibited from being opened to prevent a second train from entering.

[0011] Furthermore, it also includes control for non-communication train operation scenarios, with the specific steps as follows: When the train is not a communication train, the status of the axle counting section is monitored. If the train is traveling in the down direction and the timing starts when the train head enters the PJ axle counting section before the tunnel entrance, and the timing restarts when the PH axle counting section changes from idle to occupied, the ventilation system stops operating when both the PJ and PH axle counting sections become idle.

[0012] Furthermore, it also includes the following steps: By issuing a command to the resource controller to enable or disable the automatic triggering of the ECS function through the automatic train monitoring system, the resource controller begins to monitor the status of trains in the tunnel in real time and executes the intelligent environmental control method steps for rail transit tunnels.

[0013] This specification provides one or more embodiments of an intelligent environmental control system for rail transit tunnels, including: The onboard controller is used for train positioning and movement authorization calculation. It pre-configures ventilation system protection zones in the electronic map and authorizes movement from the stopping point to the boundary of the protection zone. The resource controller is configured via an interlocking table to control a single train to enter the tunnel based on train status information. When the train reaches the stopping point, it monitors the start and stop conditions of the ventilation system according to the set conditions. If the train's zero-speed state time exceeds the preset stopping time, it controls the tunnel ventilation system to deliver air in the direction of the train's route. The ventilation system stops operating when the train's start-up time exceeds the preset running time or when the train moves away from the preset distance of the ventilation system.

[0014] Furthermore, the ventilation system protection zone is configured as follows: By pre-configuring the protection range of the ventilation system in the electronic map of the on-board controller, the train can be located in real time and its movement authorization can be calculated. The train's stopping point can be controlled to fall outside the protection area based on the protection area of ​​the ventilation system.

[0015] Furthermore, the resource controller also implements control for non-communication train operation scenarios, specifically configured for: When the train is not a communication train, the status of the axle counting section is monitored. If the train is traveling in the down direction and the timing starts when the train head enters the PJ axle counting section before the tunnel entrance, and the timing restarts when the PH axle counting section changes from idle to occupied, the ventilation system stops operating when both the PJ and PH axle counting sections become idle.

[0016] The intelligent environmental control method and system for rail transit tunnels disclosed herein have the advantages of coordinating the control of the on-board controller VOBC and the resource controller, embedding ventilation safety into the core signal logic, actively preventing trains from stopping in the ventilation system protection area through the movement authorization adjustment of the on-board controller VOBC, eliminating major safety hazards at the source, and rigidly ensuring single-train operation in the tunnel through interlocking configuration, realizing automatic monitoring of train status and automatic triggering of the ventilation system, and controlling the air supply direction according to the train direction, greatly reducing manual intervention, and responding quickly and accurately.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this invention.

[0020] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0021] Method Implementation Examples According to embodiments of the present invention, an intelligent environmental control method for rail transit tunnels is provided, such as... Figure 1 The diagram shown is a flowchart of the intelligent environmental control method for rail transit tunnels provided in this embodiment. The intelligent environmental control method for rail transit tunnels in this embodiment includes the following steps: Step S1: During train operation, the Vehicle On Board Controller (VOBC) determines the authorized stopping point to the boundary of the pre-configured ventilation system protection zone. In step S2, through interlocking logic configuration, the interlocking system controls a single train to enter the tunnel based on the train status information. When the train reaches the stopping point, the tunnel ventilation system is controlled to deliver air in the direction of the train's route according to the train's direction of travel.

[0022] The intelligent environmental control method for rail transit tunnels provided in this embodiment coordinates the on-board controller VOBC and RC control, embeds ventilation safety into the core signal logic, and actively avoids trains stopping in the ventilation system protection area by adjusting the movement authorization of the on-board controller VOBC, thus eliminating major safety hazards at the source. Furthermore, the interlocking configuration rigidly guarantees the operation of a single train in the tunnel, realizes automatic monitoring of train status and automatic triggering of the ventilation system, and can control the air supply direction according to the train direction, greatly reducing manual intervention and providing a fast and accurate response.

[0023] In one embodiment, the specific configuration steps of the ventilation system protection zone are as follows: by pre-configuring the ventilation system protection range in the electronic map of the on-board controller VOBC, the train's real-time positioning and movement authorization (MA) calculation are realized, and the train's stopping point is controlled to fall outside the protection zone according to the ventilation system protection area.

[0024] In this embodiment, the ventilation system protection area is based on the center point of the ventilation system and extends to the left and right by a preset distance. This area is pre-configured in the onboard electronic map of the vehicle controller VOBC, and the preset distance can be set to 65-80m. When the train is running, the vehicle controller VOBC compares its own position with the ventilation system protection area in real time and dynamically adjusts the movement authorization. By calculating and adjusting the endpoint of the movement authorization online, the train is actively guided to avoid stopping within the ventilation system protection area. This is a proactive protection strategy to prevent the train from stopping in the inefficient / dangerous areas of the ventilation system.

[0025] In this embodiment, when the train has partially crossed the protection zone but the distance is insufficient to bring it to a safe stop, the stopping point is adjusted to the boundary. That is, even if the train has crossed the ventilation system's protection zone, the movement authorization endpoint is still adjusted to the boundary point of the protection zone, which means the train has already crossed the movement authorization endpoint and needs to stop immediately.

[0026] In one embodiment, the specific implementation steps of interlocking in step S2, which controls a single train to enter the tunnel based on the train status information, are as follows: by configuring the interlocking table, the occupancy status of the tunnel area is used as the interlocking condition for route processing. If the status is occupied, the relevant signal is prohibited from being opened to prevent the second train from entering. In this embodiment, when processing the route to enter the tunnel, it is checked whether the logical section associated with the tunnel has been occupied by other trains.

[0027] In this embodiment, step S2 also sets the start / stop conditions for the ventilation system. Specifically, when the train reaches the stopping point, based on the duration of the train's zero-speed state, if it exceeds a preset stopping time, the tunnel ventilation system is controlled to supply air in the direction of the train's route. Furthermore, if the train's starting and moving time exceeds a preset running time or the train moves away from the ventilation system by a preset distance, the ventilation system stops operating. For example, if the train resumes operation for more than a certain time (e.g., 10 seconds), the relay is demagnetized, and the ventilation system stops operating. The preset stopping time can be configured within a range of 0-450 seconds, and the preset running time is... The start / stop of the ventilation system can be controlled by sending start / stop control signals through the resource controller RC to excite / demagnetize the FAN-UP / FAN-DOWN relays, ensuring that the ventilation system supplies air in the correct direction, and automatically stops the ventilation system after the train stops.

[0028] In addition to control for communication train operation scenarios, this embodiment also includes control for non-communication train operation scenarios, comprising the following steps: Step 3: When the train is a non-communication train, the resource controller (RC) realizes timing and tunnel occupancy judgment through the axle section status, and realizes control of the tunnel ventilation system.

[0029] In one embodiment, reference Figure 2 As shown, the non-communication train's operating direction includes both up and down directions. The specific steps for step S3, based on the operating direction, are as follows: Step S31: When the train is a non-communication train, monitor the status of the axle counting section. If the train is in the down direction, execute step S32; if it is in the up direction, execute step S33. Step S32: Timing begins when the train head enters the PJ axle counting section (after) before the tunnel entrance. If the PH axle counting section before the next tunnel entrance changes from idle to occupied, timing restarts. When both the PJ and PH axle counting sections become idle, the ventilation system stops operating. Here, the PJ axle counting section is the axle counting section before the tunnel entrance the train enters, and the PH axle counting section is the axle counting section before the next tunnel entrance. Step S33: When the front of the vehicle enters the PH axle meter section before the tunnel entrance, the timing starts. If the PJ axle meter section changes from idle to occupied, the timing restarts. When both the PJ and PH sections become idle, the ventilation system stops operating.

[0030] In this embodiment, the occupancy status of the tunnel area is used as the interlocking condition for route processing, fundamentally preventing multiple vehicles from entering the tunnel. At the same time, through configurable time thresholds and direction judgments, the control of the ventilation system is achieved by combining interlocking-based single-train access control with intelligent tunnel occupancy mode judgment, thus realizing the intelligent and precise start and stop of the ventilation system.

[0031] In this embodiment, an intelligent environment control setting step is also included: the Automatic Train Monitoring System (ATS) sends a command to the Resource Controller (RC) to enable or disable the automatic triggering of the ECS function, i.e., the enable or disable control of the intelligent environment control system. The Resource Controller (RC) then begins to monitor the status of the train in the tunnel in real time and executes the above-mentioned intelligent environment control method steps for rail transit tunnels.

[0032] This embodiment provides a unified global function switch and status indication through the Automatic Train Monitoring System (ATS), which enables flexible management and transparent monitoring of automatic triggering functions, ensuring convenient and reliable operation.

[0033] In one specific embodiment, the control process of the ventilation system in a rail transit tunnel is described in detail below: S101: The Automatic Train Monitoring System (ATS) receives operator instructions, sets the automatic triggering ECS ​​function to enabled, and sends this status signal to the Resource Controller (RC).

[0034] S102: Resource controller (RC) continuously monitors whether there are trains inside the tunnel.

[0035] S103: When a train is detected, determine whether the train is in a zero-speed stop state. If so, start the timer.

[0036] S104: Determine whether the timer has exceeded the preset threshold T. If it has not timed out, return to continue monitoring; if it has timed out, determine that the tunnel is occupied and execute S105.

[0037] S105: According to the planned running direction of the train, the resource controller RC sends a FAN-UP or FAN-DOWN relay activation command, the ventilation system starts, and air is delivered in the specified direction.

[0038] S106: The resource controller (RC) continuously monitors the train status and determines whether the train has moved and has been running for more than a set time. If not, the ventilation system remains running; if so, proceed to S107.

[0039] S107: The resource controller (RC) sends a command to disconnect the corresponding ventilation system relay, the tunnel fan stops running, and the process ends.

[0040] The beneficial effects of the method of the present invention are as follows: (1) Deep system integration and active safety protection: By combining the coordination of VOBC, RC and ATS information, ventilation safety is embedded in the core signal logic, which realizes deep integration. The active protection of "preventing stopping in dangerous areas" is realized through the movement authorization calculation of VOBC, and the hard constraint of "single train access" is realized through the interlocking logic of RC, forming an active safety system of pre-event prevention and in-event control, which is different from traditional independent control or simple linkage.

[0041] (2) Intelligent decision-making and adaptive control: Based on configurable time thresholds, the system automatically identifies tunnel occupancy and intelligently determines the train's direction of travel, thereby automatically controlling the fans to deliver air in the correct direction. The entire process achieves full-process intelligence from perception (train status), decision-making (tunnel occupancy judgment) to execution (fan start-up and shutdown).

[0042] (3) Full-mode train compatibility: It takes into account the judgment logic of both communication trains (based on precise location and zero speed state) and non-communication trains (based on axle section occupancy state), and is compatible with all operating scenarios.

[0043] (4) Flexible and configurable global management: The Automatic Train Monitoring System (ATS) provides a global “enable / disable” switch, giving operators a high degree of flexibility and control, while ensuring the transparency and centralized management of the system status.

[0044] System Implementation Examples According to embodiments of the present invention, an intelligent environmental control system for rail transit tunnels is provided, such as... Figure 3 The diagram shown is a block diagram of an intelligent environmental control system for a rail transit tunnel provided in this embodiment. According to this embodiment, the intelligent environmental control system for a rail transit tunnel includes: The onboard controller VOBC is used for train positioning and movement authorization calculation. It pre-configures ventilation system protection zones in the electronic map and authorizes movement from the stopping point to the boundary of the protection zone. The resource controller (RC) is configured via an interlocking table to control a single train to enter the tunnel based on train status information. When the train reaches the stopping point, it controls the tunnel ventilation system to deliver air in the direction of the train's route based on the train's direction of travel. Train status information may include train speed, direction of travel, etc.

[0045] The intelligent environmental control system for rail transit tunnels provided in this embodiment integrates the on-board controller VOBC and RC, embedding ventilation safety into the core signal logic. By adjusting the movement authorization of the on-board controller VOBC, it actively avoids trains stopping within the ventilation system protection area, eliminating major safety hazards at the source. Furthermore, through interlocking configuration, it rigidly guarantees the operation of a single train within the tunnel, enabling automatic monitoring of train status and automatic triggering of the ventilation system. It can also control the air supply direction according to the train direction, significantly reducing manual intervention and providing a fast and accurate response.

[0046] In this embodiment, the ventilation system protection area is based on the center point of the ventilation system and extends to the left and right by a preset distance. This is pre-configured in the vehicle electronic map of the vehicle controller VOBC. The preset distance can be set to 65-80m.

[0047] In this embodiment, the resource controller RC is specifically configured to use the occupancy status of the tunnel area as the interlocking condition for route processing through the interlocking table. If the tunnel is occupied, the relevant signals are prohibited from being opened to prevent a second train from entering.

[0048] In this embodiment, the resource controller RC sets the start and stop conditions of the ventilation system. Specifically, when the train runs to the stopping point, if the train's zero-speed state time exceeds the preset stopping time, the tunnel ventilation system is controlled to deliver air to the direction of the train's route according to the train's route direction. When the train's starting and moving time exceeds the preset running time or the train moves away from the ventilation system by a preset distance, the ventilation system stops operating.

[0049] In this embodiment, the resource controller (RC) also implements control for non-communication train operation scenarios, specifically configured for: When the train is not a communication train, the status of the axle counting section is monitored. If the train is traveling in the down direction and the timing starts when the train head enters the PJ axle counting section before the tunnel entrance, and the timing restarts when the PH axle counting section changes from idle to occupied, the ventilation system stops operating when both the PJ and PH axle counting sections become idle.

[0050] In this embodiment, the occupancy status of the tunnel area is used as the interlocking condition for the resource controller RC route processing, fundamentally preventing multiple vehicles from entering the tunnel. At the same time, through configurable time thresholds and direction judgments, the control of the ventilation system is realized by combining the single-train access control based on interlocking with the intelligent tunnel occupancy mode judgment, thereby realizing the intelligent and precise start and stop of the ventilation system.

[0051] refer to Figure 4 As shown, this embodiment also includes an Automatic Train Monitoring System (ATS), which sends a command to the Resource Controller (RC) to enable or disable the automatic triggering of the ECS function. After receiving the command, the Resource Controller (RC) begins to monitor the status of the train in the tunnel in real time and executes the ventilation system control process described above.

[0052] Specifically, the Automatic Train Monitoring System (ATS) provides a human-machine interface. Dispatchers can use the top-level menu or right-click on the station name on the ATS workstation to issue commands to the Resource Controller (RC) to "enable" or "disable" the automatic triggering of the ECS function. The ATS interface displays the status indicator of this function in real time; for example, a green light indicates that it is enabled, and a red light indicates that it is disabled.
