[0001] This invention relates to the field of data processing technology, and in particular to a communication channel evacuation system and method. Background Technology

[0002] With the rapid development of technology, subways have gradually been applied to all aspects of people's lives. However, subways sometimes experience sudden malfunctions, which can cause them to stop operating and require the timely evacuation of passengers.

[0003] Currently, passengers are being evacuated via the evacuation platforms corresponding to the subway sections.

[0004] However, due to the low-lying terrain of the subway, the staircases corresponding to the evacuation platforms are easily flooded during heavy rainfall, making it impossible to evacuate people. Summary of the Invention

[0010] Secondly, embodiments of the present invention also provide a method for evacuating communication channels, the method comprising:

[0011] Environmental information of the train section is obtained by detecting environmental detectors within the train section.

[0029] Example 1

[0030] Figure 1 This invention provides an evacuation system for communication channels, as described in Embodiment 1. This embodiment is applicable to situations involving the evacuation of personnel through communication channels.

[0031] See Figure 1 The evacuation system 100 shown is specifically as follows:

[0032] The connecting passage evacuation system 100 is configured in the area formed by the train section and the connecting passage. The connecting passage evacuation system includes: an information processor 102, an environmental detector 101 configured in the train section, and a personnel evacuation platform 103 in the junction area of ​​the train section and the connecting passage. The environmental detector 101 is wirelessly connected to the information processor 102, and the information processor 102 is wirelessly connected to the personnel evacuation platform 103. The environmental detector 101 is used to detect the section environmental information corresponding to the train section. The information processor 102 is used to generate platform operation commands corresponding to the personnel evacuation platform 103 based on the section environmental information, and control the personnel evacuation platform 103 to expand and contract.

[0033] The connecting passage evacuation system 100 can be a combination of evacuation equipment designed to address the problems of water ingress into connecting passages or disruption of evacuation routes in subway sections during extreme weather events such as heavy rain. The train section can be the track area between two stations on the main subway line, including tunnels, track beds, and evacuation platforms, and is the core area for normal train operation. The connecting passage can be a transverse passage connecting the left and right subway tunnels, normally used for equipment inspection or maintenance, and serving as a crucial passage for personnel evacuation across lines in emergencies. Located at the break between evacuation platforms, the entrance and exit of the connecting passage are easily flooded during heavy rain. The information processor 102 can be a programmable logic controller (PLC), serving as the information processing center of the connecting passage evacuation system 100, integrating data reception, analysis, and command generation and distribution functions, and capable of wireless communication with other devices. The environmental detector 101 can be a device for detecting the environmental conditions within the train section. The personnel evacuation platform 103 can be deployed at the junction of the train section and the connecting passage. It can create a temporary barrier-free evacuation passage through its telescopic movement, filling the gaps in the connecting passage where traditional evacuation platforms are disconnected. The material must have fireproof, anti-slip, and corrosion-resistant properties. Wireless communication connection can be achieved by transmitting data and instructions between devices via wireless signals (such as IoT, Bluetooth, or Wi-Fi), replacing traditional wired connections. This avoids short circuits or signal interruptions caused by rainwater ingress, ensuring the reliability of device linkage in extreme scenarios. Section environmental information can be environmental data related to the train section collected by environmental detectors. Platform operation commands can be control commands generated by the information processor 102, including "open or close" and "telescopic speed" of the personnel evacuation platform 103. Through the commands issued by the information processor 102, the personnel evacuation platform 103 is driven to extend or retract. When extended, it can create a temporary passage across the disconnected connecting passage; when retracted, it can be stored in a safe position to avoid damage from water impact.

[0034] Specifically, the deployment and communication debugging of all components in the connecting passage evacuation system 100 can be performed first to ensure that the equipment is in a ready state. Based on the historical environmental information of the train section, the installation location of the environmental detector 101 can be preset. For example, if the historical water depth in the train section's historical environmental information is 0.3 meters, the environmental detector 101 can be deployed on the concrete wall beside the track within the train section, 0.2 meters above the track surface. The personnel evacuation platform 103 is installed at the junction of the train section and the connecting passage, and its telescopic mechanism (remote control, electric and manual drive modes) is debugged to ensure that the limit switches and protection switches are working properly. The information processor 102 is installed in a waterproof and shockproof location within the train section to complete wireless communication pairing with the environmental detector 101 and the personnel evacuation platform 103. The environmental detector 101 can collect section environmental information and convert the section environmental information (such as low-level water accumulation, depth 0.2m) into electrical signals, which are then sent to the information processor 102 via wireless communication. After receiving the section environmental information, the information processor 102 analyzes it in conjunction with preset rules to determine whether the personnel evacuation platform 103 needs to be activated. If the personnel evacuation platform 103 needs to be activated, a corresponding platform operation command is generated. After the platform operation command is generated, it is sent to the personnel evacuation platform 103 via wireless communication. After receiving the command, the personnel evacuation platform 103 performs the extension and retraction action.

[0035] The technical solution of this invention involves configuring a connecting passage evacuation system within the area formed by the train section and the connecting passage. An environmental detector is wirelessly connected to an information processor, which in turn is wirelessly connected to a personnel evacuation platform. The environmental detector detects environmental information corresponding to the train section. The information processor generates platform operation commands for the personnel evacuation platform based on the environmental information, controlling the platform to expand and contract. By analyzing the environmental information detected by the environmental detector, the information processor determines the expansion and contraction method of the personnel evacuation platform, improving the accuracy of determining the expansion and contraction method. Simultaneously, controlling the platform to expand and contract according to the specified method avoids the problem of low evacuation efficiency due to environmental influences, thus improving overall evacuation efficiency.

[0036] like Figure 2 As shown, optionally, the environmental detector 101 includes: a personnel detector 201 and a water level detector 202; the personnel detector 201 is wirelessly connected to the information processor 102, and the personnel detector 201 is used to detect whether there are personnel to be evacuated in the train section, and serves as the section environmental information corresponding to the train section; the water level detector 202 is wirelessly connected to the information processor 102, and the water level detector 202 is used to detect the water level depth in the train section, and serves as the section environmental information corresponding to the train section.

[0037] The personnel detector 201, which can be a core sub-component of the environmental detector 101, can be installed on an evacuation platform 1 meter from the opening of the connecting passage within the train section to identify whether there are personnel to be evacuated within the train section. The water level detector 202, another core sub-component of the environmental detector 101, is used to detect the depth of accumulated water and the rising trend of the water level within the train section. Personnel to be evacuated can be passengers or staff who need to be transferred from the train to the evacuation platform to a safe area due to train section shutdowns (such as flooding from heavy rain or fire). The water level depth can be the height of the accumulated water above the rail surface within the train section, determining whether the water level threatens the normal use of the evacuation platform.

[0038] Specifically, the personnel detector 201 can be an infrared sensor. Its installation location can be preset based on its performance parameters. For example, it can be installed 1m from the entrance of the connecting passage and 0.8m above the evacuation platform. The scanning angle of the personnel detector 201 can be adjusted to ensure coverage of the connecting passage entrance and the evacuation platform area within a 5m radius around the connecting passage, preventing missed personnel detection. The water level detector 202 can be preset based on historical environmental information. For example, it can be installed 0.2m from the rail surface, using point-contact detection to ensure that even slight water accumulation triggers the sensor. The personnel detector 201 and water level detector 202 are wirelessly paired with the information processor 102, and the data transmission stability is tested to ensure that the information collected by the personnel detector 201 and water level detector 202 is uploaded in real time without delay. Personnel detector 201 can scan the monitoring area. When a train makes an emergency stop due to flooding in the section, and passengers move from the train doors to the evacuation platform and towards the connecting passage, personnel detector 201 can identify "personnel movement" through infrared thermal imaging. Personnel detector 201 converts the collected signals into digital personnel information, such as "there are people waiting to be evacuated near the connecting passage" and "the number of people is about 20," and marks the collection time. When rainwater flows back into the tunnel and the water level rises, water level detector 202 comes into contact with the accumulated water, triggering a detection signal and generating water level information: "Initial flooding in the train section, water depth 0.2m." Personnel detector 201 and water level detector 202 transmit the collected personnel information and water level information to information processor 102 in real time through a preset wireless communication link. During transmission, the device number and data validity identifier can be attached. Information processor 102 can use this to determine which sensor the data comes from and whether it is valid data (to avoid mistransmission of interference signals). After receiving the data, information processor 102 integrates the two types of information into complete section environmental information.

[0039] The system utilizes environmental detectors, including personnel detectors and water level detectors. The personnel detectors are wirelessly connected to the information processor and are used to detect whether there are personnel to be evacuated in the train section, providing environmental information for that section. The water level detectors are also wirelessly connected to the information processor and are used to detect the water level depth in the train section, providing environmental information for that section. By combining personnel and water level data, the system can determine the environmental information of the section, thus improving the accuracy of the determination.

[0040] like Figure 3 As shown, optionally, the water level detector 202 includes: a low-level water immersion detector 301 and a high-level water immersion detector 302; the low-level water immersion detector 301 is wirelessly connected to the information processor 102, and the high-level water immersion detector 302 is wirelessly connected to the information processor 102; the low-level water immersion detector 301 is used to detect low-level detection information of the train section and determine it as the water level depth of the train section; the high-level water immersion detector 302 is used to detect high-level detection information of the train section and determine it as the water level depth of the train section.

[0041] The low-level water immersion detector 301 can be a sub-detection unit of the water level detector 202, installed in a low-level area near the rail surface to detect initial water ingress (shallow water accumulation) in the train section. The high-level water immersion detector 302 can also be a sub-detection unit of the water level detector 202, installed in a high-level area near the evacuation platform to detect whether the water depth has reached a level that threatens the evacuation platform (moderate or deep water accumulation). The low-level detection information can be the specific height of the shallow water accumulation collected by the low-level water immersion detector 301, used to determine whether initial water ingress has occurred in the section and trigger a level one warning. The high-level detection information can be the depth of the high-level water accumulation collected by the high-level water immersion detector 302, used to determine whether the water accumulation threatens the evacuation platform and trigger a level two warning.

[0042] Specifically, the low-level water immersion detector 301 can be installed at a preset height above the rail surface, fixed to the side wall or ballast bed, ensuring that the sensor's detection end is perpendicular to the rail surface. It will trigger when there is only slight water accumulation (approximately 0.2m or more), while avoiding positional shifts caused by train vibrations. The high-level water immersion detector 302 can be laid along the tunnel wall 0.3m below the emergency evacuation platform, ensuring that it can quickly detect water accumulation and trigger an alarm when the water level rises to this height. Both detectors are wirelessly paired with the information processor 102 (using a strong anti-interference IoT wireless protocol). The low-level water immersion detector 301 triggers for "shallow water accumulation (0.2m-0.3m)," while the high-level water immersion detector 302 triggers for "deep water accumulation (≥0.3m, threatening the evacuation platform)." The two detectors monitor in parallel in real time, triggering detection gradually according to the rising water level, collecting water accumulation information at the corresponding height. When rainwater flows back into the tunnel and the water level rises from the track surface to 0.2m, the detection end of the low-level water immersion detector 301 contacts the water, generating the low-level detection information "water level reached 0.2m" and marking the collection timestamp to avoid data corruption. If the rainstorm continues, the water level rises at a rate of 0.05m / minute, reaching 0.3m after about 4 minutes, submerging the high-level water immersion detector 302. The high-level water immersion detector 302 immediately collects the signal, generating the high-level detection information "water level reached 0.3m". If there is no water accumulation in the section, both detectors are in standby mode and can continuously scan the environment, sending a "no water accumulation" status signal to the information processor 102 at a preset frequency to ensure normal equipment operation. Each detector encapsulates its own detection information (including water level depth, collection time, and device number) into a standardized data frame and sends the data frame to the information processor 102 in real time through a preset wireless communication link. The transmission process has a retransmission mechanism; if a single transmission fails, it will automatically retransmit within 1 second to ensure that data is not lost in extreme environments. The detector has a built-in backup power supply. If the power is lost due to water ingress in the area, the backup power supply can keep the equipment running for 1.5 hours to ensure that the detection information is not interrupted during the water level rise.

[0043] The system utilizes water level detectors, including a low-level water immersion detector and a high-level water immersion detector. Both the low-level and high-level water immersion detectors are wirelessly connected to an information processor. The low-level water immersion detector detects low-level information within the train section and determines it as the water level depth of that section. The high-level water immersion detector detects high-level information within the train section and determines it as the water level depth of that section. This dual-detector system allows for comprehensive water level detection information.

[0044] like Figure 4As shown, optionally, the personnel evacuation platform 103 includes: a command processing module 401, a retractable platform 402, a limit switch 403, and a protection switch 404; the command processing module 401 is configured on the personnel evacuation platform 103, and the limit switch 403 and the protection switch 404 are installed on the personnel evacuation platform 103; the command processing module 401 can receive platform control commands generated by the information processor 103 and control the personnel evacuation platform 103 to extend and retract at the indicated speed in the platform control command; the limit switch 403 is used to control the personnel evacuation platform 103 to extend and retract to a preset position; the protection switch 404 is used to control the personnel evacuation platform 103 to stop extending and retracting.

[0045] The command processing module 401 serves as the control center of the personnel evacuation platform 103, integrated within the platform body. It possesses wireless signal reception, command parsing, and drive control functions. Its core function is to interface with the information processor 102 and convert the commands into execution signals for platform extension and retraction. The retractable platform 402 serves as the main structure of the personnel evacuation platform 103, made of fire-resistant, insulating, anti-slip, and corrosion-resistant composite materials. It can be driven to extend and retract via a servo motor (electric) or rack and pinion (manual). After extension, it can cross the disconnection gap at the connecting passage to fix the platform. The limit switch 403 serves as the travel control component of the personnel evacuation platform 103, installed at both ends of the platform's extension track. Its core function is to limit the extension and retraction range of the retractable platform, ensuring that the platform automatically stops after extending to a preset safe position, preventing excessive extension and retraction from damaging the equipment or exceeding the tunnel clearance. The protection switch 404 serves as the safety protection component of the personnel evacuation platform 103, installed on the platform's drive mechanism and load-bearing structure. Its core function is to immediately cut off the drive power and force the platform to stop extending and retracting when the platform experiences jamming, overload, or tilting, ensuring the safety of equipment and personnel. When the personnel evacuation platform 103 extends to a designated position, for example, the personnel evacuation platform 103 can extend to a designated position on the evacuation platform of the adjacent section on the same side, and the personnel to be evacuated can walk through the personnel evacuation platform 103 to reach the adjacent section and evacuate from the adjacent section.

[0046] Specifically, the command processing module 401 is embedded in the control box of the retractable platform 402 and connected to the control circuit of the drive motor to ensure that the command processing module 401 can output electrical signals to drive the motor. Limit switches 403 are installed at both ends of the telescopic track of the retractable platform 402, and the trigger positions of the switches are adjusted to match the preset extension or retraction limits. Protection switches 404 are installed at the platform drive motor and the load-bearing beam, and overload thresholds are set (e.g., triggering when the motor current exceeds 10A) to ensure rapid response in case of failure. Wireless communication pairing between the command processing module 401 and the information processor 102 is completed, and the stability of command reception is tested to ensure that the module can accurately identify commands such as "extension or retraction" and "speed parameters". When the information processor 102 determines that "high-level water ingress and traditional path interruption" occurs, it generates a platform control command (such as "extend, speed 0.5m / s") and sends it to the command processing module 401 via a wireless link. Upon receiving the command, the command processing module 401 extracts the extension direction and speed parameters and converts them into motor drive signals (e.g., extension corresponds to forward rotation of the motor, retraction corresponds to reverse rotation; speed 0.5m / s corresponds to the motor's output power level). The command processing module 401 sends a drive signal to the servo motor, which drives the retractable platform 402 to extend towards the communication channel at a preset speed. When the platform extends to... At a preset position (e.g., 2m), the limit switch 403 at the end of the travel is triggered. The limit switch sends a "position signal" to the command processing module 401, which immediately cuts off the motor power, and the platform stops extending. After evacuation is completed, when the personnel detector 201 detects that all evacuees have moved away from the communication passage, it sends evacuation completion information to the information processor 102. After receiving the evacuation completion information, the information processor 102 issues a "retract" command to the command processing module 401. The command processing module 401 drives the motor to reverse, and the platform retracts to the initial position, triggering the retracted end limit switch again to complete the reset.

[0047] The personnel evacuation platform includes: a command processing module, a retractable platform, limit switches, and safety switches. The command processing module is configured on the personnel evacuation platform, and the limit switches and safety switches are installed on the platform. The command processing module can receive platform control commands generated by the information processor and control the personnel evacuation platform to extend and retract at the indicated speed in the platform control commands. The limit switches are used to control the personnel evacuation platform to extend and retract to a preset position. The safety switches are used to control the personnel evacuation platform to stop extending and retracting. The extension and retraction of the personnel evacuation platform can be remotely controlled, and the safety of extension and retraction is ensured by the limit switches and safety switches.

[0048] like Figure 5As shown, optionally, the connecting passage evacuation system 100 also includes: an evacuation direction indicator light 501, which is wirelessly linked to the information processor 102; the information processor 102 is used to determine the evacuation direction information corresponding to the personnel to be evacuated based on the low-level detection information and high-level detection information of the train section; the evacuation direction indicator light is used to display the corresponding evacuation direction based on the evacuation direction information generated by the information processor 102.

[0049] The evacuation direction indicator 501 can be an evacuation guidance component of the connecting passage evacuation system 100. It is installed in prominent locations such as the entrance to the connecting passage or key intersections of the evacuation platform. It has wireless signal reception and direction switching display functions. Its core function is to intuitively display the safe evacuation direction according to the instructions of the information processor 102, guiding passengers to evacuate quickly. The evacuation direction indicator 501 and the information processor 102 transmit wirelessly to ensure uninterrupted communication in extreme environments such as heavy rain or power outages. The evacuation direction information can be a decision command generated by the information processor 102 combining high-level and low-level detection information. It is mainly divided into two categories: "evacuate to the opposite section" (for fixed platforms) or "evacuate to the same section" (for fixed platforms that are flooded).

[0050] Specifically, two sets of indicator lights are installed at each entrance to the connecting passage, and one set of indicator lights is installed at the junction of the evacuation platform and the connecting passage. The installation height is 2.2m (in line with human visual habits), ensuring that the indicator light's luminous angle covers 180° with no blind spots. The indicator lights are waterproof, explosion-proof, and have emergency power supply design, with built-in backup batteries, allowing them to work continuously for more than 2 hours after a power outage. The evacuation direction indicator lights 501 are wirelessly paired with the information processor 102. The information processor 102 presets evacuation direction determination rules: Rule 1: Only low-level detection information is triggered (shallow water accumulation, fixed platform not submerged), the evacuation direction information is "evacuate to the opposite section"; Rule 2: High-level detection information is triggered (deep water accumulation, fixed platform submerged), the evacuation direction information is "evacuate to the same section". The low-level water immersion detector 301 and the high-level water immersion detector 302 collect water level data of the section respectively, and upload the low-level detection information and the high-level detection information to the information processor 102 in real time via a wireless link. The information processor 102 performs fusion verification on the two types of data, eliminates invalid interference signals (such as false triggering of the low-level sensor caused by train vibration), and confirms the authenticity and validity of the water level data. Simultaneously, it receives the "personnel location information" uploaded by the personnel detector 201 to identify the area where the personnel to be evacuated are located. The information processor 102 generates corresponding evacuation direction information based on preset rules and water level data: Scenario A: Only low-level detection information is triggered. If only the "shallow water accumulation 0.2m" information from the low-level water immersion detector 301 is received, and there is no signal from the high-level detector, it is determined that the fixed evacuation platform in the connecting passage is available, and evacuation direction information is generated: "Arrow points to the opposite section, prompt text "The opposite section is safe, please evacuate from here." Scenario B: High-level detection information is triggered. If the "deep water accumulation 0.3m, fixed platform submerged" information from the high-level water immersion detector 302 is received, it is determined that the traditional evacuation route is interrupted, and evacuation direction information is generated: "Arrow points to the station on the same side, prompt text "Connecting passage is flooded, do not enter, evacuate to the station on the same side." The information processor 102 transmits the generated evacuation direction information to all evacuation direction indicator lights 501 via a wireless link. The control module of the indicator light parses the instruction and immediately switches the display status: In scenario A, the indicator light illuminates with a green arrow pointing to the opposite section, and the prompt text is displayed scrolling synchronously; In scenario B, the indicator light illuminates with a red prohibition sign (indicating that the communication channel is unavailable), and a green arrow points to the same side of the station, and the prompt text is updated synchronously. The evacuation direction indicator lights 501 send a "display status normal" signal to the information processor 102 every 30 seconds to ensure that the guidance function is not interrupted. If the evacuation direction indicator lights 501 malfunction, the information processor 102 immediately pushes an alarm to the station control room.

[0051] The evacuation system via the communication channel also includes: evacuation direction indicator lights, which are wirelessly linked to the information processor; the information processor is used to determine the evacuation direction information corresponding to the personnel to be evacuated based on the low-level detection information and high-level detection information of the train section; the evacuation direction indicator lights are used to display the corresponding evacuation direction based on the evacuation direction information generated by the information processor, and can guide the personnel to be evacuated to evacuate accurately by displaying the evacuation direction through the evacuation direction indicator lights.

[0052] like Figure 6 As shown, optionally, the communication passage evacuation system 100 further includes: a handwheel drive device 601 and a button drive device 602. The handwheel drive device 601 is connected to the personnel evacuation platform 103, and the button drive device 602 is connected to the personnel evacuation platform 103. The handwheel drive device 601 is used to trigger the extension and retraction of the personnel evacuation platform 103 by means of a handwheel. The button drive device 602 is used to trigger the extension and retraction of the personnel evacuation platform 103 by means of a button.

[0053] The handwheel drive device 601 can be a purely mechanical emergency drive component of the personnel evacuation platform 103, directly connected to the gear and rack transmission mechanism of the retractable platform 402 of the personnel evacuation platform 103. Its core function is to allow personnel to manually turn the handwheel to extend or retract the personnel evacuation platform 103 and establish an evacuation passage in extreme situations where there is a complete power outage within the train section and wireless commands fail. The button drive device 602 can be a local electric drive component of the personnel evacuation platform 103, which can be installed in a waterproof control box on the side of the personnel evacuation platform 103. It is equipped with two physical buttons for "extend or retract". Its core function is to allow on-site personnel to manually press the button to directly control the extension or retraction of the personnel evacuation platform 103 when wireless communication fails (such as signal interruption) but backup power is still available.

[0054] Specifically, the button drive device 602 can be installed inside the button control box, which is mounted on the side of the personnel evacuation platform 103 at a height of 1.5m (for easy operation). The internal circuitry is connected to the servo motor and backup power supply of the personnel evacuation platform 103. It features three-position buttons: "Extend / Stop / Retract," and is equipped with a waterproof and dustproof cover to prevent accidental triggering by rain. A handwheel is installed at the end of the gear and rack mechanism of the personnel evacuation platform 103. In manual mode, turning the handwheel directly drives the gear and rack, propelling the personnel evacuation platform 103 to extend or retract. The priority settings for the three drive modes are as follows: Priority 1: Remote wireless drive (instructions are issued by the information processor 102 and executed by the command processing module 401); Priority 2: Local button drive (in case of wireless failure, manual button pressing prioritizes backup power drive); Priority 3: Manual handwheel drive (in case of complete power failure, mechanical transmission drive). Based on the premise that the water level detector 202 triggers the high-level detection information, and combined with different fault scenarios, the corresponding drive mode is activated: Scenario 1: The evacuation system of the connecting passage is 100% fault-free, the high-level detection information is triggered, wireless communication is normal, and the mains power is normal, then remote wireless drive is possible. Scenario 2: Wireless communication failure, the high-level detection information is triggered, the wireless signal is interrupted, and the backup power supply is available, local button drive is used. Scenario 3: Complete power failure, the high-level detection information is triggered, and all backup power supplies fail, manual handwheel drive is used.

[0055] The evacuation system via the communication channel also includes: a handwheel drive device and a button drive device. The handwheel drive device is connected to the personnel evacuation platform, and the button drive device is also connected to the personnel evacuation platform. The handwheel drive device is used to extend and retract the personnel evacuation platform by handwheeling. The button drive device is used to extend and retract the personnel evacuation platform by button. The reliability of the personnel evacuation platform extension and retraction is ensured through three modes: remote control, electric drive, and manual drive.

[0056] like Figure 7 As shown, optionally, the information processor 102 is wirelessly connected to the station control room 701; the information processor 102 is used to generate alarm prompt information based on the section environmental information and send the alarm prompt information to the station control room 701.

[0057] Among them, the station control room 701 can be a communication device for the subway command department, which can generate work information such as inter-section train operation, emergency dispatch and rescue command. It is the receiving end of the information processor 102 that uploads alarm information, and also the decision-making and execution end of subsequent emergency measures.

[0058] Specifically, the information processor 102 is connected to the subway's dedicated wireless communication network and bound to the command terminal in the station control room 701. A dedicated communication port is set up to ensure the security and uniqueness of data transmission and avoid signal confusion with other devices. Preset alarm classification rules: Level 1 alarm trigger condition: only low-level detection information is received (shallow water accumulation, no threat to evacuation platforms), no personnel detection information; Level 2 alarm trigger condition: high-level detection information is received (deep water accumulation, fixed platforms are submerged), and personnel detection information is received simultaneously (passengers awaiting evacuation). Fixed formats are set for different alarm levels to ensure that the station control room can quickly read key information after receiving the data. The information processor 102 receives low-level and high-level detection information uploaded by the water level detector 202, as well as personnel location information uploaded by the personnel detector 201 in real time; the information processor 102 verifies the validity of the received data to eliminate false alarms caused by sensor malfunctions or signal interference. Information processor 102 determines the alarm level based on preset rules and water level and personnel data. For example, if only the low-level flood detector 301 uploads "0.2m shallow water accumulation", it is determined to be a Level 1 alarm; if the high-level flood detector 302 uploads "0.35m deep water accumulation" and the personnel detector uploads "50 passengers near the connecting passage", it is determined to be a Level 2 alarm. Information processor 102 generates and encapsulates standardized alarm prompts based on the determined alarm level. For example, the information content for the two levels is as follows: Level 1 Alarm, [Alarm Type] Initial water ingress in the section, [Location] XX point in the section between Station A and Station B of Line XX, [Severity Level] Level 1, [Current Status] Low water level 0.2m, no personnel remaining, [Recommended Measures] Start the drainage pumps and closely monitor the water level rise trend. Level 2 alarm, [Alarm Type] Severe flooding in the section + personnel awaiting evacuation, [Location] Section XX between Station A and Station B on Line XX, [Severity Level] Level 2, [Current Status] High water level 0.35m, 50 passengers awaiting evacuation near the connecting passage, fixed platform submerged, [Recommended Measures] Immediately activate the section disaster mode, cut off non-firefighting power, dispatch rescue personnel to assist, and activate personnel evacuation platform 103. The information processor 102 transmits the encapsulated alarm information in real time to the command terminal in the station control room 701 via a preset wireless communication link, and simultaneously to the handheld terminals of on-site rescue personnel. After receiving the alarm information, the command terminal in the station control room 701 automatically sends a "received" confirmation signal to the information processor 102. If no confirmation signal is received within 10 seconds, the processor automatically retransmits to ensure no information loss. If the environmental information of the section changes (such as a continuously rising water level or personnel evacuation), the information processor 102 updates the alarm content in real time and pushes it again.After receiving the alarm information, the station control room 701 will activate the corresponding emergency measures according to the severity level. Level 1 alarm: dispatchers will remotely start the drainage pump in the section and closely monitor the changes in water level data. No on-site rescue is required. Level 2 alarm: the section disaster mode will be activated immediately, instructing the trains in the section to make an emergency stop, cut off non-fire-fighting power supply and open the tunnel ventilation system. At the same time, rescue personnel will be arranged to go to the scene with emergency equipment to pick up passengers.

[0059] The information processor is wirelessly connected to the station control room. It generates alarm information based on the section environment information and sends the alarm information to the station control room, which can provide timely alarms and improve the safety of personnel evacuation.

[0060] Example 2

[0061] Figure 8 This is a flowchart illustrating a communication channel evacuation method according to Embodiment 2 of the present invention. This embodiment of the invention is applicable to personnel evacuation via communication channels. The method can be executed by a communication channel evacuation device, which can be implemented in hardware and / or software. This communication channel evacuation device can be configured within communication channel evacuation equipment; this embodiment of the invention does not impose any limitations on this.

[0062] It should be noted that for parts not described in detail in the embodiments of the present invention, please refer to the descriptions in other embodiments.

[0063] See Figure 8 The evacuation methods for the communication channels shown include:

[0064] S801. The environmental information of the train section is obtained by detecting the environmental detectors within the train section.

[0065] Specifically, before detecting environmental information in the test section, the environmental detectors must be installed and debugged to ensure hardware readiness. The fixing method must prevent train vibration and displacement. Environmental detectors may include water level detectors and personnel detectors. The detection end of the water level detector must be perpendicular to the rail surface, ensuring that contact detection is triggered when water reaches the detector's position. The water level detector and information processor are then wirelessly paired, and data transmission stability is tested to ensure real-time uploading of collected signals without delay or packet loss. When uploading water level information to the information processor, the water level detector can include the acquisition time and detector number. The detector uploads this information to the information processor in real-time via a wireless link. Personnel detectors, which can be infrared detection devices, can detect the presence of personnel awaiting evacuation in the train section. If a personnel detector collects personnel information, it uploads this information to the information processor. The information processor integrates the personnel and water level information to determine the corresponding environmental information for the train section.

[0066] S802: Obtain section environment information through the information processor and generate platform operation commands.

[0067] Specifically, the information processor pre-programs decision rules strongly correlated with water level and personnel status, as follows: If only low-level detection information is triggered, no personnel are approaching and the fixed evacuation platform is available, there is no need to activate the telescopic platform; the platform remains in a retracted standby state. If only low-level detection information is triggered, personnel are approaching and the fixed platform is available; personnel can pass through the platform normally, and the platform remains in a retracted standby state. If high-level detection information is triggered, no personnel are approaching and the fixed platform is flooded, but there is no immediate need for evacuation, the platform remains in a retracted standby state, continuously monitoring personnel information. If high-level detection information is triggered, personnel are approaching the communication channel, the fixed platform is flooded, the evacuation route is interrupted, and a temporary passage needs to be built, the platform extends to a preset position (crossing the gap in the communication channel) at a preset speed (e.g., 0.5 m / s). Personnel have already evacuated, but high-level detection information still exists; there is no need to maintain the temporary passage, the platform is retracted to avoid damage, and retracts to its initial position at a preset speed. Meanwhile, the information processor needs to preset the platform's safety parameters: extension speed threshold (adjustable from 0.3-0.8 m / s), extension limit position (e.g., 2.2 m, set according to the actual size of the section), and emergency fault instructions (e.g., immediate stop in case of jamming). The information processor synchronously receives two types of core data through a wireless communication link: water level detection information from the water level detector and personnel detection information from the personnel detector. The information processor filters the received data to eliminate interference signals and ensure accurate decision-making: if the water level sensor has no continuous signal after a single trigger, it is judged as interference and not included in the section's environmental information; if the personnel sensor detects personnel but there is no subsequent movement signal within 10 seconds, it is judged as a stationary object (e.g., luggage) and excluded from the personnel evacuation status. The information processor will use the verified water level information and personnel information to complete logical judgment based on the rules matching and decision-making of environmental information, divided into 4 typical scenarios: Scenario 1: Low risk and no demand (only low-level water inflow, no personnel information), after matching the rules, it is determined that the fixed platform is available and there is no evacuation demand, and the decision result is "the personnel evacuation platform remains on standby and does not perform extension or retraction actions". Scenario 2: Low risk with personnel (only low-level water ingress, personnel information available), section environmental information is "low-level detection triggered, water level 0.2m, personnel passing through the communication channel". After matching the rules, it is determined that: the fixed platform is not flooded, personnel can be evacuated normally, and the decision result is still "the platform remains in retracted standby state". Scenario 3: High risk with no personnel (high-level water ingress, no personnel information), section environmental information is "high-level detection triggered, water level 0.35m, no personnel approaching". After matching the rules, it is determined that: the fixed platform is flooded, but there is no need for personnel evacuation at present. The decision result is "the platform is on standby, continuously monitoring personnel information, and will be activated immediately once personnel are detected". Scenario 4: High risk with personnel (high-level water ingress, personnel information available), section environmental information is "high-level detection triggered, water level 0.35m, personnel waiting to be evacuated in the communication channel". After matching the rules, it is determined that: the fixed platform is ineffective, and a temporary passage needs to be urgently built. The decision result is "activate the personnel evacuation platform and extend it to the preset position".Based on the decision-making results, the information processor generates standardized platform operation commands and encapsulates these commands to ensure accurate execution by the personnel evacuation platform. The commands contain three core elements: action commands, parameter commands, and safety commands. Taking scenario 4 (high-risk with personnel) as an example, the generated commands are: Action command: Extend (clarifying the platform's movement direction); Parameter command: Extension speed 0.5 m / s, extension limit position 2.2 m (clarifying movement parameters); Safety command: Stop immediately after triggering the limit switch, trigger the protection switch if stuck (clarifying safety boundaries). For a retraction scenario after personnel evacuation, the command would be: Retract, speed 0.4 m / s, retract to the initial position, trigger the limit switch to stop. The information processor encapsulates the generated commands into standardized data frames that the device can recognize, including: a unique identifier for the personnel evacuation platform (to avoid sending commands to the wrong device); command execution priority: highest priority (ensuring emergency commands are executed first); and command validity period: 1 minute (if not executed within the time limit, it will be resent to avoid signal loss). After encapsulation, the information processor temporarily stores the platform operation command in the sending queue. When the wireless communication link is idle, it immediately sends the command to the command processing module of the personnel evacuation platform. At the same time, it records the command generation time and content for easy traceability later.

[0068] S803: The information processor sends the platform operation command to the personnel evacuation platform to control the personnel evacuation platform to expand and contract according to the platform operation command.

[0069] Specifically, once the information processor completes rule matching and decision-making, and generates a valid platform operation command (such as "extend, speed 0.5m / s, extreme position 2.2m"), it immediately triggers the delivery program without manual intervention. If a single transmission fails, the processor will automatically retransmit within 1 second, up to 3 times, to ensure the command is delivered. The delivered command data frame contains a unique device number for the personnel evacuation platform. Only platforms with matching numbers will receive and parse the command, preventing multiple devices in the same area from mistakenly executing it. The command processing module of the personnel evacuation platform is the core of command reception and parsing. It monitors the wireless communication frequency band in real time. After receiving the command from the information processor, it first verifies the device number and validity period: if the number does not match, the command is discarded without any action; if the number matches but the validity period has expired, it reports "command timed out" to the information processor and requests retransmission; if the number matches and the command is within the validity period, it enters the command parsing stage. The command processing module 401 extracts the core parameters from the data frame and converts them into electrical signals recognizable by the platform's drive system: Action parameters: converting the "extend or retract" command into a forward or reverse drive signal for the servo motor; Speed ​​parameters: converting "0.5m / s" into the motor's power level signal (e.g., 0.5m / s corresponds to power level 3); Position parameters: comparing "limit position 2.2m" with the platform's built-in travel parameters and setting it as the trigger threshold for the limit switch. Simultaneously, it detects the platform's power supply status and automatically matches the drive mode: if the power supply is normal, the electric drive mode is activated, driving the servo motor; if the power is completely lost, command parsing fails, the module triggers an audible and visual prompt, guiding on-site personnel to switch to handwheel drive mode. Figure 9The diagram shows a schematic of the evacuation system for the connecting passage. It consists of a low-level water immersion sensor 1, a high-level water immersion sensor 2, an evacuation direction indicator 3, a personnel evacuation platform 4, an information processor 5, and a personnel detector 8. The low-level water immersion sensor 1 uses a contact-type water immersion sensor for point-type leakage detection, reducing the false alarm rate; its installation height is 0.2m above the rail surface. The high-level water immersion sensor 2 uses a linear water immersion monitoring sensor, installed at a height 0.3m below the emergency evacuation platform. The evacuation direction indicator 3 is an evacuation indicator that can switch between indicating the evacuation direction. The personnel evacuation platform 4 uses equipment that can achieve two starting methods: electric servo motor or manual rack and pinion drive. It is equipped with electric and manual operation buttons and handwheels on-site, and has remote control capabilities. Its operating speed can be configured by adjusting parameters. The personnel evacuation platform uses a 24V safety voltage control and has limit switches and protective switches to ensure safe and reliable operation during the extension and retraction process. The materials used in the personnel evacuation platform have fire-resistant and insulating properties, are corrosion-resistant, moisture-resistant, and slip-resistant. The information processor 5 consists of a programmable logic controller and input / output modules. Personnel detector 8, using infrared detection or millimeter-wave radar, is installed 0.8 meters above the evacuation platform and 1 meter from the opening of the connecting passage. Low-level water immersion sensor 1, high-level water immersion sensor 2, evacuation direction indicator 3, personnel evacuation platform 4, and personnel detector 8 are all linked to information processor 5. When low-level water immersion sensor 1 detects water ingress in the section, it sends an alarm message to information processor 5. Information processor 5 then sends a water ingress alarm to the control room of the station to which the section belongs, reminding personnel to execute the corresponding section disaster mode, activating the tunnel ventilation, drainage pumps, and emergency evacuation system, cutting off non-fire-fighting power to prevent electric shock, and immediately stopping trains in the corresponding interlocking zone and evacuating passengers via the evacuation platform. When personnel detector 8 detects passengers approaching the section connecting passage, it sends personnel information to information processor 5. Information processor 7 then sends personnel location information to the control room of the station to which the section belongs, reminding rescue personnel to proceed. The information processor controls the direction indicated by evacuation direction indicator 3 and the opening and closing of personnel evacuation platform 4 based on the alarm information from personnel monitoring sensor 8 and high-level water immersion sensor 2. When the high-level water immersion sensor 2 detects water ingress in the unaffected section, the evacuation direction indicator shows evacuation to the opposite section 7, and the personnel evacuation platform 4 remains closed. If the high-level water immersion sensor 2 detects water ingress in the section, it sends an alarm message to the information processor 5, and the evacuation direction indicator shows evacuation to the same-side section 6, and the personnel evacuation platform 4 opens. If the personnel evacuation platform 4 cannot be remotely controlled to open, passengers can open it using a local button. If the equipment loses power, passengers can manually open it using the handwheel and rack and pinion mechanism. When the personnel detector 8 detects passengers leaving the section's connecting passage, it sends personnel information to the information processor 7, which then sends the personnel location information to the control room of the station to which the section belongs, alerting rescue personnel to go to the scene for secondary confirmation.

[0070] This invention, in its embodiment, configures the connecting passage evacuation system within the area formed by the train section and the connecting passage. An environmental detector is wirelessly connected to an information processor, which in turn is wirelessly connected to a personnel evacuation platform. The environmental detector detects environmental information corresponding to the train section. The information processor generates platform operation commands for the personnel evacuation platform based on the environmental information, controlling the platform to expand and contract. By analyzing the environmental information detected by the environmental detector, the information processor determines the expansion and contraction method of the personnel evacuation platform, improving the accuracy of determining this method. Furthermore, by controlling the platform to expand and contract according to the specified method, the invention avoids the problem of low evacuation efficiency due to environmental factors, thus improving overall evacuation efficiency.

[0071] Optionally, the information processor acquires the section environmental information and generates platform operation commands, including: acquiring the water level depth from the section environmental information through the information processor; determining the water level data range corresponding to the water level depth based on the water level depth; finding the evacuation rules corresponding to the water level data range based on the water level data range; and generating platform operation commands based on the evacuation rules.

[0072] Specifically, the information processor receives low-level and high-level detection information from water level detectors and personnel location information from personnel detectors via a wireless communication link. The information processor extracts a water level depth determination value according to the following rules: if only low-level detection information is triggered, the water level depth is determined to be 0.2m (the installation height of the low-level water immersion detector); if high-level detection information is triggered, the water level depth is determined to be 0.3m (the installation height of the high-level water immersion detector); if no detection information is triggered, the water level depth is determined to be 0m. The information processor compares the extracted and verified water level depth determination value with a preset water level data range division standard to accurately match the corresponding interval, with four typical cases: water level depth determination value = 0m, matching the 0m (no water accumulation) data range; water level depth determination value = 0.2m, matching the 0.15m~0.3m data range; water level depth determination value = 0.35m, matching the ≥0.3m data range. Based on the water level data range, the corresponding evacuation rules are retrieved. The information processor uses a lookup table to match the pre-defined evacuation rules within the determined water level range. For a range of "0m", the retrieved rule indicates that the fixed evacuation platform is usable and does not require activation of the telescopic platform. For a range of "0.15m~0.3m", the retrieved rule indicates that the fixed evacuation platform remains usable and personnel can pass normally. For a range of "≥0.3m", the retrieved rule indicates that the traditional evacuation route is interrupted and a temporary passage needs to be built using the telescopic platform. Based on these evacuation rules, the information processor converts them into executable platform operation commands.

[0073] The system acquires section environmental information through an information processor and generates platform operation commands, including: acquiring water level depth from the section environmental information through the information processor; determining the water level data range corresponding to the water level depth; finding the evacuation rules corresponding to the water level data range based on the water level data range; and generating platform operation commands based on the evacuation rules. Different platform operation command generation methods can be executed for different water level depths, refining the steps of platform operation command generation and improving the accuracy of platform operation command determination.

[0074] Optionally, after obtaining the water level depth from the section environmental information through the information processor, the method further includes: determining evacuation direction information based on the water level depth, wherein the evacuation direction information includes: arrow direction and prompt text.

[0075] Specifically, water level depth 0m (no water accumulation): all routes are safe, including fixed evacuation platforms, connecting passages, and station passages on the same side; water level depth 0.15m~0.3m (low-level flooding): connecting passages and fixed platforms are determined not to be flooded, and the opposite section is the better evacuation direction (closest); water level depth ≥0.3m (high-level flooding): connecting passages and nearby fixed platforms are determined to be flooded, traditional cross-line routes are invalid, and only the station passages connected to the evacuation platforms on the same side are safe. The information processor generates a decision result based on the above judgment rules and environmental information. Based on the decision result, the information processor 102 generates standardized evacuation direction information, which must include two core elements: arrow direction (visual guidance) and prompt text (text description). Scenario 1: Low risk (water level 0.2m, low-level flooding), arrow direction: green one-way arrow pointing to the opposite section; prompt text: "The opposite section is safe, please evacuate through the connecting passage"; information encapsulation: the arrow direction and prompt text are integrated into a data frame and marked "low-risk guidance". Scenario 2: High Risk (Water Level 0.35m, High-Level Flooding), Arrow Direction: A red prohibition arrow is displayed at the entrance of the connecting passage, and a green one-way arrow is displayed on the evacuation platform, pointing towards the station on the same side; Prompt Text: "Connecting passage is flooded, do not enter! Evacuate to the station on the same side"; Information Encapsulation: The arrow direction and prompt text are integrated, marked "High Risk Guidance," and a warning sign "Do Not Enter Connecting Passage" is added. After the information processor generates the evacuation direction information, it will simultaneously execute two linked actions: the information is transmitted wirelessly to all evacuation direction indicator lights, and the indicator lights immediately switch their display status according to the information content; the evacuation direction information is included in the alarm prompt information and pushed to the station control room, so that the operation personnel can grasp the on-site guidance situation and assist in rescue dispatch.

[0076] After obtaining the water level depth from the environmental information of the section through the information processor, the method also includes: determining the evacuation direction information based on the water level depth. The evacuation direction information includes: arrow direction and prompt text. The arrow direction and prompt text can be used to guide the people to be evacuated, ensuring the accuracy of the evacuation.
