DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0019] The specific implementation of the present invention is described below with reference to the accompanying drawings.

[0020] Example 1 like Figure 1 As shown, the present invention proposes a tunnel flood prevention intelligent management platform, which can realize centralized monitoring of tunnels, drainage facility management and maintenance, equipment operation monitoring, data collection and analysis, etc. under daily working conditions. Under accident conditions, the platform promptly obtains on-site monitoring data, event progress, equipment status and other information, and activates emergency plans according to the accident level. Through the data interface connected to emergency management platforms at all levels, the tunnel accident condition information is uploaded to the superior management departments such as traffic police, water affairs, and urban management, so as to realize the dispatch of surrounding emergency resources and efficient rescue.

[0021] This system promptly detects flooding characteristics, issues alarm signals, performs graded processing, quickly evacuates people and vehicles, activates tunnel flood prevention settings, protects electromechanical facilities in the tunnel, and guides traffic outside the tunnel. It is an integrated tunnel disaster prevention and mitigation system. It obtains the water level in the tunnel and the operating status of equipment in real time, and conducts inspections of the water level in the tunnel and the operating status of equipment under daily working conditions. Under accident conditions, it determines the accident warning level based on the water level in the tunnel and the operating status of equipment, activates the emergency plan, realizes emergency resource scheduling and accident reporting, and takes corresponding flood prevention measures in a timely manner.

[0022] Specifically, it includes inspection system, early warning system, flood prevention facility system, traffic guidance system and linkage control system.

[0023] Inspection system: used to inspect the water level in the tunnel and the operating status of the equipment in the tunnel. If the water level in the tunnel is greater than the preset threshold, the water level in the tunnel and the operating status of the equipment in the tunnel will be transmitted to the early warning system; otherwise, it is determined whether the equipment in the tunnel has an operation warning. If an operation warning occurs, the maintenance department is notified to carry out repairs; the operation warning includes water leakage warning and overpressure warning.

[0024] Furthermore, the inspection system consists of tunnel water level warning facilities, tunnel water inflow warning facilities, pipeline leakage warning facilities, and pipeline overpressure warning facilities; The tunnel water level warning facility is used to monitor the water level in the tunnel, and when at least one of the water levels in the tunnel exceeds a preset threshold, a water accumulation warning is given; The tunnel water inflow warning facility is used to monitor whether water outside the tunnel enters the tunnel. When at least one of the tunnel water inflow warning facilities monitors whether water outside the tunnel enters the tunnel, a water inflow warning is given; The pipeline leakage warning facility is used to monitor whether the pipeline in the tunnel is leaking. When at least one of the pipeline leakage warning facilities detects a pipeline leakage, a leakage warning is given; The pipeline overpressure warning facility is used to monitor whether the pressure of the pipelines in the tunnel exceeds a preset pressure threshold. When the pressure of at least one pipeline exceeds the preset pressure threshold, an overpressure warning is given.

[0025] The inspection system is a key component of the intelligent management platform for tunnel flood prevention. It is responsible for real-time monitoring of the water level and equipment operation status in the tunnel. The system can comprehensively monitor the water conditions and equipment status in the tunnel by deploying water level warning facilities, water inflow warning facilities, pipeline leakage warning facilities and pipeline overpressure warning facilities. When it is detected that the water level exceeds the preset threshold or the equipment operation is abnormal, the inspection system will immediately transmit the relevant data to the early warning system so that further emergency measures can be taken. In addition, the inspection system also has judgment and notification functions, which can identify operational warnings such as leakage and overpressure, and promptly notify the maintenance department for processing to ensure the safe operation of the tunnel.

[0026] Early warning system: Based on the water level in the tunnel and the operating conditions of the equipment in the tunnel, obtain tunnel accident condition information, determine the accident warning level, activate the emergency resource dispatch plan, and upload the tunnel accident condition information to the superior management department.

[0027] Tunnel accident condition information includes tunnel location, affected area, water level, equipment status and predicted impact. Tunnel accident condition information is a key data set used in the tunnel flood prevention intelligent management platform to quickly respond to and handle emergencies in the tunnel. It covers the specific location of the tunnel, the area affected by water accumulation, the real-time water level, the equipment operating status and the predicted impact of the accident, providing an accurate basis for emergency decision-making and ensuring that effective measures are taken in a timely manner to ensure tunnel safety.

[0028] The method for determining the accident warning level is as follows: When the water level in the tunnel exceeds the preset threshold but does not exceed the safety threshold, the accident warning level is the primary flood prevention warning; When the water level in the tunnel exceeds the safety threshold, the accident warning level is a high-level flood prevention warning.

[0029] The emergency plan corresponding to the primary flood warning is: The early warning system automatically sends early warning information to the control center, links the monitoring room's LED to display the monitoring screen at the early warning signal, and simultaneously sends out an audible and visual alarm; Calculate the change in water depth within T time at the warning signal. If the change in water depth within T time is less than the preset water change threshold, cancel the primary flood prevention warning. Otherwise, adjust the primary flood prevention warning to a high-level flood prevention warning. After canceling the primary flood prevention warning, it also includes: determining whether there is a water leakage warning and / or overpressure warning. If so, notify the maintenance department to perform repairs.

[0030] The emergency response plan corresponding to the advanced flood warning is: Start the flood prevention facility system: start the drainage pump and equipment protection device at the water accumulation warning point; if there is a water inflow warning, start the automatic flood prevention baffle; if there is a water leakage warning, start the pipeline electric valve; Activate the traffic guidance system: activate public information push, information intelligence board broadcast, activate the lane interception system, and traffic control measures to inform vehicles outside the tunnel of the water accumulation in the tunnel and prohibit vehicles outside the tunnel from entering to ensure the safety of people in the vehicle.

[0031] Further, such as Figure 2 As shown in the figure, the calculation method of the change in water depth within time T is: Step B1: Calculate the amount of water Q flowing from the i-th water accumulation point to the j-th water accumulation point at time t ij (t), ; Among them, A i is the cross-sectional area of ​​the ith water accumulation point; g is the gravitational acceleration; is the water level difference between the ith water accumulation point and the jth water accumulation point at time t; W is the cross-sectional width of the ith water accumulation point; f is the friction factor; L ij is the length of water flow from the i-th water accumulation point to the j-th water accumulation point; Step B2: Calculate the volume change V of the water at the ith water accumulation point within T time. i (T), ; Among them, Q ki (t) is the amount of water flowing from the kth water accumulation point to the ith water accumulation point at time t; I i (t) is the amount of water entering the i-th water accumulation point at time t; i (t) is the amount of water discharged from the i-th water accumulation point at time t; The amount of water flowing from the kth water accumulation point to the ith water accumulation point is the movement of water caused by the water level difference between the two places. The amount of water entering the ith water accumulation point may be the increase of the water volume in the ith water accumulation point caused by water pipe bursting, water pumps, etc., while the amount of water discharged from the ith water accumulation point may be the reduction of the water volume in the ith water accumulation point by methods such as water pumps and diversion.

[0032] Step B3: Calculate the change in water depth H at the ith waterlogging location within time T. i (T), .

[0033] When calculating the change in water depth, the focus is usually on the water accumulation over a short period of time (such as a few hours or days). On this time scale, the physical structure of the tunnel is unlikely to change significantly, so it is reasonable to assume that the cross-sectional area A i is constant.

[0034] The method for calculating the change in water depth within time T is achieved by comprehensively analyzing the flow changes, cross-sectional area and water flow dynamics at each water accumulation point in the tunnel. This method first calculates the flow from the water accumulation point to other areas, and then determines the change in the volume of the water accumulation based on the difference in the amount of water flowing in and out, combined with the cross-sectional area of ​​the water accumulation point. Finally, the volume change is divided by the cross-sectional area of ​​the water accumulation point to obtain the change in water depth within time T. The key to this calculation process is real-time monitoring of flow, water level difference and accurate measurement of cross-sectional area, so as to ensure that the calculation of the change in water depth is accurate and provide scientific data support for the intelligent management platform for tunnel flood prevention.

[0035] The early warning system is one of the core functions of the intelligent management platform for tunnel flood prevention. It evaluates the safety status of the tunnel in real time by analyzing the water level and equipment operation status data in the tunnel collected by the inspection system. The system can determine the early warning level of the accident based on the monitored changes in the water level and equipment status, thereby triggering the corresponding emergency plan. The early warning system can not only automatically send early warning information to the control center, but also ensure rapid response through sound and light alarms and monitoring screen prompts. In addition, the system can also intelligently determine whether it is necessary to raise the early warning level from primary to advanced based on the change in the depth of water accumulation within T time, and cancel the early warning when necessary, thereby reducing false alarms and unnecessary emergency actions, and improving the accuracy of early warnings and the efficiency of emergency response.

[0036] Flood prevention facility system: including automatic flood prevention baffles, pipeline electric valves, drainage pumps and equipment protection devices, which are used to prevent water outside the tunnel from entering the tunnel, prevent equipment in the tunnel from being splashed and flooded by water, and drain the accumulated water in the tunnel in time to realize the tunnel's flood prevention function.

[0037] The flood prevention facility system is an important part of the intelligent management platform for tunnel flood prevention. It forms a complete tunnel flood prevention solution by integrating key equipment such as automatic flood prevention baffles, pipeline electric valves, drainage pumps and equipment protection devices. The system is designed to actively prevent external water sources from entering the tunnel and quickly remove the accumulated water in the tunnel to protect the tunnel structure and internal equipment from water damage. When the early warning system detects the risk of water accumulation, the flood prevention facility system can be automatically or manually started to effectively control and reduce the water level in the tunnel through a combination of physical blocking and mechanical drainage to ensure the safe operation of the tunnel and smooth traffic.

[0038] Traffic guidance system: including broadcast voice, water depth warning, information board, traffic lights, single and double lane interception system, used for information broadcasting, escape guidance, traffic diversion, and evacuation of people and vehicles according to the accident warning level given by the warning system.

[0039] The traffic guidance system is a key component of the intelligent tunnel flood prevention management platform to ensure traffic safety inside and outside the tunnel. It responds to the accident warning level issued by the warning system in real time through multiple means such as broadcast voice, water depth warning, information intelligence board, traffic lights, and single and double lane interception system. When the tunnel is flooded or other emergencies occur, the system can quickly provide the driver with accurate water accumulation conditions and safety guidance, implement effective traffic diversion and control measures, guide vehicles to bypass safely, and prevent vehicles and personnel from entering dangerous areas, thereby ensuring the safety of personnel and traffic order inside and outside the tunnel.

[0040] Linkage control system: used to activate flood prevention facilities and conduct traffic guidance according to the accident warning level given by the early warning system.

[0041] The linkage control system is the core link in the intelligent management platform for tunnel flood prevention. Through a highly integrated management strategy, it realizes the unified coordination and command of multiple key subsystems in the tunnel, such as the inspection system, early warning system, flood prevention facility system and traffic guidance system. The system can automatically or manually trigger the corresponding emergency plan based on real-time monitoring data and early warning information to ensure that various flood prevention measures and traffic guidance measures can be implemented quickly and orderly in the event of tunnel waterlogging or other emergency situations. The efficient operation of the linkage control system improves the tunnel's response speed and processing capabilities to deal with emergencies, and minimizes the impact of accidents on personnel safety and traffic operations.

[0042] The tunnel flood prevention intelligent management platform of the present invention is a comprehensive intelligent system that provides comprehensive technical support for safe tunnel operation by integrating advanced monitoring, early warning, emergency response and rescue functions. The platform can monitor the water level and equipment status in the tunnel in real time, intelligently analyze the data and determine the early warning level, and automatically start the corresponding flood prevention measures and traffic guidance plans. In an emergency, it can quickly dispatch emergency resources and implement effective rescue operations to ensure the safety of people inside and outside the tunnel and smooth traffic. The efficient linkage control and intelligent management of this platform have significantly improved the tunnel's disaster prevention and mitigation capabilities, and are an important technical support for modern urban tunnel safety management.

[0043] Example 2 like Figure 3 As shown, the present invention also proposes a tunnel flood prevention intelligent management method, using the tunnel flood prevention intelligent management platform as described in any one of the embodiments 1, specifically comprising the following steps: Step S1, obtaining the water level in the tunnel, if the water level is less than a preset threshold, proceed to step S2, otherwise proceed to step S3; Step S2, inspect the operation status of the equipment in the tunnel, and if an operation warning occurs, notify the maintenance department to carry out maintenance; otherwise, return to step S1; the operation warning includes water leakage warning and overpressure warning; Step S3, transmitting the water level in the tunnel and the operating status of the equipment in the tunnel to the early warning system, linking the monitoring room's LED to display the monitoring screen at the early warning signal, and synchronously issuing an audible and visual alarm; Step S4, obtaining tunnel accident condition information and determining the accident warning level according to the water level in the tunnel and the operating conditions of the equipment in the tunnel; Step S5, if the accident warning level is the primary flood prevention warning, the warning system automatically sends a warning message to the control center; calculates the change in water depth at the warning signal within the time T, and if the change in water depth at the water accumulation point within the time T is less than the preset water accumulation change threshold, cancels the primary flood prevention warning, otherwise adjusts the primary flood prevention warning to a high-level flood prevention warning; Step S6: if the accident warning level is a high-level flood prevention warning, the emergency resource dispatch plan is activated, and the tunnel accident condition information is uploaded to the superior management department; Step S7, start the drainage pump and equipment protection device at the place where the water accumulation warning appears; if the water inflow warning appears, start the automatic anti-flooding baffle; if the water leakage warning appears, start the pipeline electric valve; Step S8, start public information push, information board broadcast, start lane interception system, and traffic control measures to inform vehicles outside the tunnel of the water accumulation in the tunnel and prohibit vehicles outside the tunnel from entering to ensure the safety of people in the car.

[0044] The intelligent management method for tunnel flood prevention is an innovative and comprehensive management strategy. It relies on an advanced intelligent management platform for tunnel flood prevention. It monitors the water level and equipment operation status in the tunnel in real time, and intelligently judges and responds to various potential flood threats in a graded manner. The method covers the entire process from daily inspections to accident warnings, emergency resource dispatch and rescue operations, ensuring that corresponding flood prevention measures and traffic guidance plans can be quickly taken under different levels of warnings. Through highly automated and intelligent control processes, the tunnel's emergency response capabilities in the face of extreme weather and natural disasters have been significantly improved, ensuring the safe operation of the tunnel and smooth traffic.
