[0002] In the later stages of excavation for underground powerhouses in water conservancy and hydropower projects, access tunnels, ventilation tunnels, exhaust shafts, and various construction adits are connected. These numerous interconnected chambers form a complex labyrinth, and ventilation in the underground powerhouse is affected by each chamber, resulting in chaotic airflow and making airflow organization extremely difficult.

[0003] To create an effective ventilation loop, both access tunnels and ventilation tunnels (hereinafter referred to as construction tunnels) are equipped with curtain partitions. Some access tunnels and ventilation tunnels are selectively opened or closed, while bypasses are blocked and main roads are opened, forming a complete and stable cycle from the "air inlet" to the "air outlet." At this time, on the one hand, some construction tunnels must be kept closed to ensure ventilation; on the other hand, these construction tunnels also undertake the transportation of engineering vehicles, machinery, equipment, and materials during construction, serving as a necessary path to ensure on-site operations.

[0004] In existing technologies, in construction tunnels with frequent traffic and harsh environments, ventilation quality is often sacrificed for traffic convenience, resulting in chaotic management and an inability to simultaneously guarantee traffic efficiency and ventilation effectiveness.

[0022] It should be noted that "at the time of..." in the embodiments of this application can be either at the instant when a certain situation occurs, or for a period of time after the occurrence of a certain situation. The embodiments of this application do not make specific limitations on this.

[0023] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This application provides a ventilation isolation control method based on construction openings, which can be applied to, for example... Figure 1 In the application environment shown, each construction opening corresponds to a ventilation isolation control device 102. The ventilation isolation control device 102 can be a computer device such as a terminal, server, or controller. Multiple ventilation isolation control devices 102 are connected to a central control server 101. The ventilation isolation control devices 102 are connected to the central control server 101 via a network. Both the central control server 101 and the ventilation isolation control devices 102 can include a data storage system to store relevant data. The data storage system can be set up separately or integrated into the central control server 101 / ventilation isolation control device 102.

[0025] The central control server 101 can send control commands to the ventilation isolation control device 102 to set the corresponding construction tunnel to open and form a complete and stable main ventilation channel. It can also send normally closed mode commands to the ventilation isolation control devices 102 of other construction tunnels. The isolation control device 102 is used to execute the ventilation isolation control method based on construction tunnels provided in this application, controlling the tunnel door of the corresponding construction tunnel to be in a normally closed state to ensure continuous and stable ventilation of the main ventilation channel. When there is vehicle traffic, the tunnel door is opened and closed to ensure traffic efficiency, ventilation effect, and safety inside the tunnel.

[0026] like Figure 2 A ventilation isolation control system based on a construction tunnel includes a roadside communication unit installed at the tunnel entrance, a radar module / millimeter-wave radar, a ventilation isolation control device 102, a gas monitoring sensor, and a tunnel entrance mechanism 103, wherein: Onboard Unit: If all vehicles are equipped with a V2X communication module (Vehicle-to-Everything Communication Module), it is generally an OBU (On-Board Unit). The OBU periodically broadcasts vehicle-to-everything data signals; vehicle-to-everything data signals generally include vehicle ID, location information, speed information, and acceleration information, etc.

[0027] Roadside Unit (RSU): Located at a predetermined distance in front of the tunnel entrance. This unit serves as a V2X communication interface, receiving vehicle-to-everything (V2X) data signals periodically broadcast by the onboard units of all connected vehicles within its wireless coverage area, and transmitting this information to the local control unit.

[0028] Radar module / millimeter-wave radar: Acquires radar signals from vehicles approaching the tunnel entrance. These vehicles may be connected to the vehicle network or not, and will be captured by the millimeter-wave radar to generate radar signals. The radar signals generally include: signal identification, location information, and speed information.

[0029] Gas monitoring sensor: used to monitor the content of harmful gases near the opening and transmit the data to the central control server 101 and / or ventilation isolation control device 102; The ventilation isolation control device 102 also includes: Communication module: responsible for parsing the data stream transmitted from the roadside communication unit.

[0030] Command receiving and forwarding module: Receives door curtain control commands issued by an external intelligent control center, or generates control commands according to the method provided in this application, and forwards the commands to the door execution mechanism 103.

[0031] Status feedback module: Acquires the working status of the acquisition device itself and feeds it back to the central control server; Backup sensing interface: Located on the local control unit, it provides a standardized electrical and communication interface for connecting one or more backup sensors. When the V2X communication link is invalid, target sensing signals from these external sensors (such as millimeter-wave radar) can be input through this interface, allowing the device to switch to backup sensing drive mode.

[0032] The doorway mechanism can be a roller shutter door and its motor, or other door control mechanisms. Taking a roller shutter door as an example, the doorway mechanism includes a roller shutter door status sensor, a roller shutter door motor, and a roller shutter door actuator. It is generally connected to the ventilation isolation control device 102 via an industrial bus or control cable and is the mechanical moving part of the device. It includes: Roller shutter door motor: preferably a servo motor or frequency converter motor with precise position control and electromagnetic braking function, used to drive the roller shutter door's roller shaft.

[0033] Roller shutter door actuator: generally includes a roller and a door curtain body, driven by a drive motor, used to roll up and release the door curtain body. The door curtain body hangs down naturally or is equipped with a counterweight bar to form a stable partition.

[0034] Status sensor: Integrated inside the door mechanism, used to detect the roll-up / lower position of the door curtain, the running / stopping / fault status of the motor, and the output torque in real time. The above signals are fed back to the local control unit in real time.

[0035] In one exemplary embodiment, such as Figure 3 As shown, a ventilation isolation control method based on construction openings is provided. This method is executed by computer equipment, specifically by a terminal or server alone, or by both a terminal and a server. In this embodiment, the method is applied to... Figure 1 / Figure 2 The following description uses the ventilation isolation control device 102 as an example, including the following steps 301 to 305: Step 301: Receive normally closed mode command, respond to normally closed mode command, open normally closed control mode, send closing command to portal mechanism, and receive radar signal and / or vehicle network data signal; Specifically, the central control server sends a normally closed mode command or a normally open mode command to the ventilation isolation control device; if a normally open mode command is received, the corresponding tunnel door is normally open as part of the main ventilation channel; if a normally closed mode command is received, in response to the normally closed mode command, the normally closed control mode is activated and a closing command is sent to the tunnel door mechanism. Correspondingly, the portal mechanism responds to the closing command and closes the portal.

[0036] Specifically, the radar signal includes the target vehicle's first position and first speed information acquired by radar. The radar signal is acquired through millimeter-wave radar, which is installed at the entrance of the construction tunnel to receive reflected radar signals.

[0037] Specifically, the vehicle-to-everything (V2X) data signals include second position information, second speed information, and second acceleration information obtained from the onboard module, which are located near the vehicle. Specifically, vehicles equipped with an on-board unit module are vehicles with vehicle-to-everything (V2X) communication capabilities, and V2X data signals are obtained based on the on-board unit; vehicles without this module are not vehicles with V2X communication capabilities.

[0038] Specifically, both the first and second location information are coordinate information with a preset point at the entrance of the tunnel as the origin. Specifically, the first location information is the coordinate information with a preset point at the entrance of the tunnel as the origin. The data acquired by the millimeter-wave radar includes distance information and azimuth information. Based on the distance information and azimuth information, the coordinate information with the millimeter-wave radar as the origin can be obtained. Then, the first location information is obtained by coordinate transformation. Specifically, the V2X communication module acquires data including latitude and longitude information, and obtains second location information based on the latitude and longitude information through coordinate transformation (such as Mercator projection).

[0039] Step 302: Determine whether the target vehicle's communication type is vehicle-to-everything (V2X) communication or non-V2X communication based on radar signals and / or vehicle-to-everything (V2X) data signals. Specifically, regardless of whether the communication is vehicle-to-everything (V2X) or non-V2X, the millimeter-wave radar will detect the incoming signals when the vehicle approaches the entrance. If it is V2X communication, the corresponding V2X data information will also be acquired. The type of communication, whether it is V2X or non-V2X, can be determined based on the radar signal and the V2X data signal.

[0040] Step 303: Obtain the optimal location information and the first gating distance based on the communication type, radar signal, and / or vehicle network data signal; Specifically, if the communication type is vehicle-to-everything (V2X) communication, the first gating distance is obtained based on V2X data signals; if the communication type is non-V2X communication, the first gating distance is obtained based on radar signals. Step 304: Based on the first gate control distance and optimal position information, issue an opening command to the tunnel portal mechanism.

[0041] Specifically, the first gate distance is obtained based on the location and speed information of the nearest vehicle, and an opening command is issued when the vehicle travels to the first gate distance.

[0042] Correspondingly, in response to the opening command, the portal mechanism opens the portal; Step 305: Update the optimal position information and, based on the optimal position information, send a closing command to the tunnel gate mechanism after the target vehicle exits the tunnel gate.

[0043] Specifically, the optimal location information is obtained according to the method in step 303.

[0044] Correspondingly, in response to the closing command, the portal mechanism closes the portal; Implementing steps 301 to 304 above, in response to the normally closed mode command, a closing command is sent to the tunnel portal mechanism to ensure continuous and stable ventilation of the main ventilation channel; by determining whether the target vehicle's communication type is vehicle-to-everything (V2X) or non-V2X based on radar signals and / or vehicle-to-everything (V2X) data signals, comprehensive identification of both V2X and non-V2X vehicles is achieved; by obtaining the first gate control distance based on radar signals and / or V2X data signals, and issuing an opening command to the tunnel portal mechanism based on the first gate control distance and current location information, the timing of tunnel portal opening is precisely controlled, achieving the acquisition of the optimal opening point. This ensures traffic efficiency while avoiding prolonged ineffective opening of the tunnel portal, thus balancing smooth traffic flow and tunnel safety.

[0045] In another exemplary embodiment of this application, in order to accurately determine the communication type of the target vehicle, step 302 above is replaced by steps 401 to 402: Step 401: If only radar signals are received, determine that the communication type is non-vehicle network communication; Step 402: If radar signals and vehicle network data signals are received simultaneously, the radar signals and vehicle network data signals are matched to determine whether the target vehicle and the approaching vehicle are the same vehicle target; if so, the communication type is determined to be vehicle network communication; if not, the communication type is determined to be non-vehicle network communication.

[0046] Specifically, both the first and second location information are coordinate information with a preset point at the entrance of the tunnel as the origin. The position deviation is obtained based on the first and second location information. If the position deviation is less than the first preset threshold, it is considered to be the same vehicle; otherwise, it is determined that they are not the same vehicle.

[0047] As one embodiment, the positional deviation is obtained according to the following formula: ; in, This is the first location information. This is the second location information. This is the positional deviation.

[0048] In another exemplary embodiment of this application, in order to obtain a more accurate first gate control distance to determine the time to open the portal, such as... Figure 4As shown, step 303 above includes steps 501 to 504. Wherein: Step 501: Based on the communication type, if the communication type is non-vehicle network communication, proceed to step 502; if the communication type is vehicle network communication, proceed to step 503. Step 502: Process the first position information and the first velocity information based on the first preset Kalman filter model to obtain the optimal position information, optimal velocity information and optimal acceleration information; then proceed to step 504. Specifically, Kalman filtering is an optimal state estimation algorithm that can estimate the optimal state of a dynamic system from noisy measurement data.

[0049] The first pre-defined Kalman filter model includes the observation vector, observation matrix, state transition matrix, state transition equation, and state update equation. Wherein: The first position and first velocity information acquired at different time points are used as input, i.e., the observation vector of each frame. Set to: ; in, Represents the input data for frame t, ( () represents the vehicle position coordinates input in frame t. This represents the x-direction velocity component of the input in frame t. This represents the y-direction velocity component measured in frame t.

[0050] As output, the state vector X t Set to: ; The state transition matrix F is set as follows: ; The observation matrix H is set as follows: ; Specifically, it is used to correspond to the observation vector.

[0051] The state transition equation is set as follows: ; in, This represents the predicted state at time t based on information from time t-1. This refers to the state of the previous frame; The state update equation is set as follows: ; in, For posterior state estimation, representing the final output of the current frame, Represents Kalman gain.

[0052] Specifically, the state transition matrix and state transition equations are based on the kinematic equations, and the prediction formula for each component can be obtained from the state transition equations: Location prediction: ; ; Speed ​​prediction: ; ; Acceleration prediction: ; Specifically, this step takes the first position information and first velocity information obtained at different time points as input, and the final output is the optimal estimate of the position information, velocity information and acceleration information at the current time, that is, the optimal position information, optimal velocity information and optimal acceleration information.

[0053] Step 503: Obtain optimal position information, optimal velocity information, and optimal acceleration information based on the second position information, the second velocity information, and the second acceleration information; As an optional embodiment, since x2v data has a certain degree of accuracy compared to radar data, the second position information, second velocity information, and second acceleration information can be directly used as the optimal position information, optimal velocity information, and optimal acceleration information to replace this step.

[0054] As another optional embodiment, this step is: processing the second position information, the second velocity information, and the second acceleration information based on the second preset Kalman filter model to obtain the optimal position information, the optimal velocity information, and the optimal acceleration information.

[0055] Specifically, since radar-based data includes position and speed, while V2X communication module-acquired data includes position, speed, and acceleration, this step sets a second preset Kalman filter model to process vehicle-to-everything (V2X) data signals to adapt to different data processing methods. This is to avoid data jitter and obtain more accurate data.

[0056] Specifically, the second preset Kalman filter model includes the observation vector, observation matrix, state transition matrix, state transition equation, and state update equation.

[0057] Specifically, due to different input values, the state transition matrix, state transition equation, and state update equation of the second preset Kalman filter model are the same as those of the first preset Kalman filter model, but the observation vector and observation matrix are different: The observation vector is the input vector, specifically: ;in, This represents the x-axis acceleration component of the input in frame t. This represents the component of the y-direction acceleration measured in frame t.

[0058] The observation matrix is: H= ; Specifically, the second position information, second velocity information, and second acceleration information obtained at different time points are used as inputs, and the final output is the optimal estimate of the position information, velocity information, and acceleration information at the current time, namely the optimal position information, optimal velocity information, and optimal acceleration information.

[0059] Step 504: Obtain the first gating distance based on the optimal velocity information, optimal acceleration information, and preset safety time using kinematic formulas. Specifically, the first gating distance is obtained according to the following formula: ; in, Indicates the first gating distance. The radial velocity is obtained based on the optimal velocity information output in the previous step. The radial acceleration is obtained based on the optimal acceleration information output in the previous step. To preset a safe time, it is generally taken as the sum of the time required to open the door and the safe time margin.

[0060] In another exemplary embodiment of this application, based on the optimal position information, optimal velocity information, and optimal acceleration information obtained in the previous step, and the first gate control distance, the safety of opening and closing the gate is further ensured. The above step 304 includes steps 601 to 604: Step 601: Obtain the optimal estimated distance based on the optimal location information; Specifically, the optimal location information is the coordinate point, and the distance from the coordinate point to the origin is obtained based on the optimal location information as the optimal estimated distance; Step 602: Determine whether the first gate distance is greater than the preset absolute safety distance; if the first gate distance is greater than the preset absolute safety distance, proceed to step 603; if the first gate distance is not greater than the preset absolute safety distance, proceed to step 604. Specifically, the preset absolute safety distance can be obtained using the following formula: ; Among them, S absolute To preset an absolute safe distance, V max D represents the maximum possible speed for vehicles traveling inside the tunnel. buffer This is the physical buffer distance.

[0061] Step 603: Determine whether the optimal estimated distance is greater than the first gate control distance. If the optimal estimated distance is not greater than the first gate control distance, issue an opening command to the tunnel portal mechanism. Step 604: Determine whether the optimal estimated distance is greater than the preset absolute safety distance. If the optimal estimated distance is not greater than the preset absolute safety distance, issue an opening command to the tunnel portal mechanism.

[0062] In another exemplary embodiment of this application, to further ensure the safety of vehicle passage, steps 304 and 305 described above can be replaced by steps 701 to 704: Step 701: Determine the vehicle type of the target vehicle based on the communication type; the target vehicle type includes one of dangerous goods transport vehicles, personnel commuter vehicles, and material transport vehicles; if the target vehicle type is used to indicate personnel commuter vehicles, proceed to step 702; if the target vehicle type is used to indicate material transport vehicles, proceed to step 703; if the target vehicle type is used to indicate dangerous goods transport vehicles, proceed to step 704. Specifically, if the communication type is vehicle-to-everything (V2X) communication, the second vehicle type is obtained based on the V2X data signal, and the second vehicle type is used as the target vehicle type. Specifically, the vehicle network data signal also includes a second vehicle type, or a second vehicle type that can be mapped based on its ID. The second vehicle type is used to indicate that the approaching vehicle is one of the following: a dangerous goods transport vehicle, a personnel commuter vehicle, or a material transport vehicle. Specifically, personnel commuter vehicles are non-freight trucks, dangerous goods transport vehicles are diesel and explosives transport vehicles, and material transport vehicles are high-frequency output vehicles such as slag trucks and concrete mixer trucks.

[0063] Specifically, if the communication type is non-vehicle-to-everything (V2X) communication, the first vehicle type is obtained based on the image recognition module and used as the target vehicle type; wherein, the first vehicle type is used to indicate that the target vehicle is one of the following: a dangerous goods transport vehicle, a personnel commuter vehicle, or a material transport vehicle. Specifically, the image recognition module can obtain images of passing vehicles in the mine and their corresponding labels as a training set based on a preset classification model. The preset classification model is trained using the training set to obtain the image recognition module. Real-time vehicle images are input into the image recognition module to obtain the target vehicle type.

[0064] Step 702: Ensure vehicle passage and instruct the tunnel portal mechanism to close using a preset first safety strategy; the preset first safety strategy includes: ventilating the tunnel entrance with a preset first ventilation volume, and issuing a closing command to the tunnel portal mechanism when the target vehicle drives out of the construction site. Specifically, in steps 702 to 704, the optimal location information is updated through steps 502 / 503 to determine whether the target vehicle has driven out of the construction site.

[0065] Optionally, when the normally closed control mode is activated, ventilation at the opening can be set to a first ventilation volume. When the first safety strategy is determined, the instruction indicating the first safety strategy can be sent to the central control server, and the central control server can be set to keep the air volume constant.

[0066] Specifically, when the target vehicle passes through the opening and the distance between it and the opening is greater than a preset distance, it can be determined that the target vehicle has exited the construction site. The distance between the target vehicle and the opening after passing through the opening can be obtained through steps 501 to 504.

[0067] Step 703: Use a preset second safety strategy to ensure vehicle passage and instruct the tunnel portal mechanism to close; the preset second safety strategy includes: when the target vehicle has driven out of the construction site, delay until a second preset time, issue a closing command to the tunnel portal mechanism; Specifically, the preset second safety strategy is designed to allow large vehicles such as slag trucks and concrete mixer trucks to pass quickly, and then close the tunnel gate after passing and delay it for a period of time. Once it is confirmed that there are no vehicles following behind, the gate is closed immediately to maintain the isolation to the greatest extent possible.

[0068] Step 704: Use a preset third safety strategy to ensure vehicle passage and instruct the tunnel portal mechanism to close; the preset third safety strategy includes: using a preset third ventilation volume to ventilate the tunnel entrance, and after the target vehicle has driven out of the construction site, delay for a third preset time and the hazardous gas index meets the requirements, issue a closing instruction to the tunnel portal mechanism. Specifically, the preset third ventilation volume is greater than the preset first ventilation volume, and the preset third time is greater than or equal to the preset second time.

[0069] Specifically, the preset second safety strategy is designed to control the interval time after a dangerous vehicle passes through, and also to activate enhanced ventilation inside the tunnel and temporarily prohibit other vehicles from entering. Normal operation will resume after the dangerous goods vehicle has safely passed through and the gas monitoring meets the standards.

[0070] Specifically, it receives data from gas monitoring sensors and determines whether hazardous gas indicators meet the standards based on thresholds.

[0071] This application provides a method for controlling ventilation isolation based on construction openings, which includes the following technical effects: By distinguishing between "non-vehicle-to-everything (V2X) communication" and "vehicle-to-everything (V2X) communication," the system uses Kalman filtering to process radar data or directly analyzes V2X data, respectively. This enables the system to be compatible with vehicles of different levels of intelligence, ensuring that all types of engineering vehicles can be effectively perceived and tracked.

[0072] For ordinary vehicles without network connectivity, a first preset Kalman filter model is used to reduce noise and optimize the original radar position and velocity information, generating smooth and accurate optimal motion state information (position, velocity, acceleration), which solves the problem of inaccurate positioning caused by radar signal fluctuations in the harsh environment inside the cave.

[0073] Based on real-time optimal speed and acceleration data of vehicles, combined with preset safety reaction time, the "first gate control distance" is dynamically calculated using kinematic formulas. This mechanism means that the timing of the gate opening is no longer fixed, but rather adaptively adjusted according to the actual speed and movement trend of the vehicles. This ensures smooth vehicle passage while minimizing unnecessary gate opening time, thus maintaining ventilation and isolation effects under the "normally closed mode" while ensuring traffic efficiency.

[0074] A refined matrix parameter design was implemented for both the first and second preset Kalman filter models to accommodate different data types. Specifically, a 1 / 2Δt parameter was introduced into the state transition matrix F. 2 Acceleration-related terms accurately characterize the uniform speed and uniform acceleration motion modes that vehicles may exhibit while traveling inside the tunnel. The first preset Kalman filter model's observation vectors only select directly measurable four-dimensional data of position and velocity, ensuring both the model's engineering feasibility and providing a rich data foundation for subsequent state prediction. A state space capable of fully describing the vehicle's planar motion characteristics is constructed. Taking advantage of the fact that the vehicle-to-everything (V2X) communication module can directly provide six-dimensional full data of position, velocity, and acceleration, the observation vectors are extended to a six-dimensional space including acceleration information. This allows the filter model to fully utilize the high-precision data advantages of V2X technology, achieving hierarchical processing and adaptive compatibility of vehicle signals with different levels of intelligence. The first preset Kalman filter model leverages the noise suppression capabilities of Kalman filtering while preserving the high-dimensional characteristics of V2X data, achieving a balance between denoising optimization and feature preservation of the original measurement data, providing a more stable and reliable motion state input for subsequent gating decisions.

[0075] By integrating vehicle type recognition and tiered safety strategies, refined classification and control of vehicles passing through the tunnel were achieved, significantly improving the collaborative management of ventilation and traffic in complex environments. For networked vehicles, type information was directly read; for non-networked vehicles, an image recognition module was introduced for supplementary identification, ensuring that all passing vehicles could be accurately classified (hazardous materials transport vehicles, personnel commuter vehicles, material transport vehicles). This provided a reliable data foundation for differentiated management and avoided management blind spots caused by unclear vehicle types. Through differentiated combinations of multi-dimensional parameters such as ventilation volume, delay time, and environmental monitoring, core safety (especially hazardous materials transport) was ensured while avoiding excessive restrictions on ordinary traffic, achieving an optimal balance between ventilation quality and transportation efficiency under complex operating conditions.
