Description

Technical Field

[0001] This invention relates to the field of water conservancy project safety management, specifically an intelligent early warning system for rubber dam safety management. Background Technology

[0002] Rubber dams are a new type of water-retaining structure, widely used as control gates and tide gates in rivers and ditches, and flood discharge gates in reservoir spillways. They play an important role in river cascade development, flood control and drainage, water ecological management, and landscape environment.

[0003] The main water-retaining structure of a rubber dam is the dam bag, a flexible, membrane-like structure that is more susceptible to damage compared to hard materials such as steel, concrete, and stone. During operation, it is easily punctured or cut by sharp objects such as branches, broken glass, and icicles, or by human sabotage. Vibration can also cause wear and tear on the rubber sheeting of the dam bag, and the impact of water flow can even lead to tearing and dam failure. In short, rubber dam projects are inherently prone to aging and damage, and are easily susceptible to external disturbances that can lead to safety accidents.

[0004] Rubber dams are generally located in river channels and are used to intercept water flow. Before raising the dam to impound water or collapsing it to release water, a warning should be issued in advance to evacuate people moving upstream and downstream and on both banks in a timely manner, and to remove engineering equipment in the river channel that is easily submerged or destroyed, so as to avoid casualties and property damage.

[0005] If the dam bag is damaged or torn, the river water impounded upstream will be released in a very short time, causing the engineering facilities in the downstream river channel to be destroyed, and people who are swimming, washing clothes, fishing, playing in the water or carrying out construction work to drown.

[0006] If the rubber dam fails to collapse in time, it will obstruct the flow of floodwaters in the river, raise the water level in the upstream river, and even cause flooding and damage.

[0007] The control and power distribution systems of rubber dams are complex and have relatively many risk points. In daily operation and management, they are prone to various safety hazards and accidents such as flooding, fire, explosion, electric shock, lightning strike, fall, mechanical impact, and power outage. These are difficult to prevent and can easily cause injury or death to management personnel.

[0008] In the existing technology, in order to avoid safety accidents of rubber dams, it mainly relies on engineering management personnel to strengthen daily inspections and monitoring, and to deal with safety hazards in a timely manner. However, it is difficult for engineering management personnel to inspect and monitor the condition of the project around the clock. Especially at night, when engineering management personnel are resting, if a malfunction occurs in the project, it will not be easily detected in time, resulting in a safety accident.

[0009] Before a rubber dam is raised to impound water or collapses to release water, the relevant street and village officials are usually notified by phone, and then they organize the evacuation of personnel and the removal of equipment. This approach makes it difficult to ensure comprehensive coverage of warnings for affected populations, and information is often difficult to disseminate in a timely manner.

[0010] The collapse of the dam is manually controlled by the engineering management personnel. If the situation of obstructing the discharge of floodwater, dam failure, or dam overflow due to misoperation is not detected and dealt with in a timely manner by the engineering management personnel, it may further lead to related safety accidents.

[0011] In the daily operation and management of rubber dam projects, if the relevant project management personnel can receive the early warning information in the first instance, they can deal with the situation in a timely manner, and the injured personnel can receive timely medical treatment, preventing the accident from escalating further and avoiding secondary disasters. If the accident is not detected and dealt with effectively in a timely manner, it can also easily lead to injury or death of management personnel.

[0012] In summary, previous methods relied on manual inspection and monitoring to identify various hazards in rubber dams and provided passive early warnings. There is an urgent need to develop an intelligent early warning system for safety management. This system would identify all risk points in the operation and management of rubber dams, and install sensors, cameras, and other detection devices at each risk point. This system would be able to detect faults or accidents in a timely manner, promptly notify management personnel for effective handling, and proactively issue early warning information to the public. Summary of the Invention

[0013] To address the aforementioned issues, an intelligent early warning system for rubber dam safety management was invented.

[0014] The technical solution of this invention is as follows: The intelligent early warning system for rubber dam safety management can proactively detect various safety problems occurring during the operation and management of rubber dams, provide early prevention, promptly report to engineering management personnel, and proactively issue early warning information to the affected parties, thereby avoiding or reducing casualties and property losses. The system mainly consists of four parts: a monitoring module, an intelligent control and analysis module, an early warning module, and a system management module. These modules interact with each other to jointly complete the safety early warning work.

[0015] The monitoring module, equipped with detectors, sensors, video surveillance, and image recognition devices, is used to monitor and detect safety issues and transmit information to the intelligent control and analysis module. This module includes: a water level and flow monitoring unit, a dam bag monitoring unit, a management monitoring unit, and a water affairs monitoring unit. The water level and flow monitoring unit monitors: water levels exceeding design or flood control limits, overflow depth exceeding limits, and dam flow exceeding design flow. The dam bag monitoring unit monitors: dam height exceeding design height, dam bag internal pressure exceeding limits, automatic dam collapse, dam bag vibration, and dam bag reverse water blocking. The management monitoring unit monitors: events threatening personal and property safety such as flooding, fire, explosion, electric shock, lightning strikes, falls, mechanical attacks, and power outages. The water affairs monitoring unit monitors: rubber dam filling and overflow, drowning and equipment submersion, dam breaches, and external intrusion.

[0016] The intelligent control and analysis module consists of a computer module with calculation, fitting, image recognition, and analysis functions. Upon receiving a safety issue detected by the monitoring module, it processes data, performs simulation analysis, executes control decisions, generates early warning information, and issues the warning to the public through the early warning module device. This module includes: a data processing and analysis unit, a storage unit, and a control execution unit. The data processing and analysis unit is used to identify and analyze safety issues, process data, and establish a visualization model to assist management personnel in analysis and decision-making. The storage unit is mainly used to store safety issue data information detected by the monitoring module, establishing a big data database for the data processing and analysis unit to retrieve necessary information. The control execution unit is used for intelligent control of the rubber dam's filling and collapse, intelligent power outage, dialing rescue calls, generating early warning information, and controlling the early warning module to issue the warning information.

[0017] After receiving the early warning information generated by the intelligent control and analysis module, the early warning module performs categorized early warning and dual-mode early warning. Categorized early warning divides the target audience into two categories: engineering management personnel and the general public. Different early warning messages and modes are developed for each category based on their specific needs. Dual-mode early warning includes two types of units: on-site early warning units and beyond-line-of-sight communication early warning units. On-site early warning units use various devices and equipment, such as voice sirens, early warning broadcasts, strobe lights, large monitoring screens, flood discharge electronic screens, warning signs, and mobile early warning vehicles, to issue safety warnings to the surrounding area. Beyond-line-of-sight communication early warning units utilize various media and methods, such as telephone, SMS, WeChat, websites, mobile clients, and WeChat official accounts, to issue beyond-line-of-sight safety warnings. Categorized and dual-mode early warnings complement each other, achieving comprehensive coverage of safety warning information to the target audience.

[0018] The system management module, primarily comprised of computer and mobile terminals, serves as the system's user management interface. It provides users with an interactive interface and data display, enabling system function calls, management, and data output. This is used for system parameter settings, system information entry, system upgrades, and other system management tasks. The module includes units such as a panoramic monitoring map, real-time monitoring data, data analysis and retrieval, monitoring and early warning management, and system function control. Furthermore, a visualization model unit can be added as needed to assist administrators in analysis and decision-making.

[0019] Compared with the prior art, the present invention has the following beneficial effects.

[0020] This invention proposes an intelligent early warning system for rubber dam safety management. Through information and intelligent technologies, sensors, video surveillance, and image recognition devices are installed on all potential hazards inside and outside the rubber dam project to conduct all-weather, all-round, and blind-spot-free monitoring. It can monitor and identify various hazards that may occur in the operation and management of the rubber dam without the need for manual monitoring and identification of hazards, saving project management personnel from frequent project inspections. This not only improves project management efficiency but also transforms manual passive defense into intelligent active defense, ensuring project safety.

[0021] After detecting and identifying a hazard, the early warning system can promptly provide feedback to engineering management personnel and issue early warning information to the affected parties, thereby avoiding or reducing casualties and property losses.

[0022] After detecting and identifying a hazard, the early warning system will provide feedback to the engineering management personnel. If the management personnel do not receive the early warning information in a timely manner, the system can perform intelligent control actions such as filling or collapsing the rubber dam, intelligent power outage, and calling for rescue, thereby preventing the accident or disaster from escalating further due to the management personnel's failure to respond in a timely manner.

[0023] The early warning system classifies and issues warnings, dividing the warning targets into two categories: engineering management personnel and the general public. Different warning information and different warning modes are formulated for each category according to the warning needs.

[0024] The aforementioned early warning system employs a dual-mode approach, utilizing both on-site early warning and beyond-line-of-sight communication early warning modes. On-site early warning disseminates safety alerts to the surrounding area through various devices and equipment, including voice sirens, warning broadcasts, strobe lights, large monitoring screens, flood discharge electronic displays, warning signs, and mobile early warning vehicles. Beyond-line-of-sight communication early warning utilizes multiple media and methods, such as telephone, SMS, WeChat, websites, mobile clients, and WeChat official accounts, to issue safety warnings beyond the immediate public eye. These two warning modes complement each other, ensuring comprehensive coverage of safety warning information to the target population. Attached Figure Description

Detailed Implementation

[0032] This invention proposes an intelligent early warning system for rubber dam safety management. This system can promptly detect various safety issues occurring during the operation and management of rubber dams, provide timely feedback to engineering management personnel, enable early prevention, and issue early warning information to those at risk, thereby avoiding or reducing casualties and property losses. The system mainly consists of four parts: a monitoring module 1, an intelligent control and analysis module 2, an early warning module 3, and a system management module 4. These modules interact to jointly complete the safety early warning work. The technical solution of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] The monitoring module 1 is used to monitor and detect safety issues and transmit the information to the intelligent control and analysis module 2. The monitoring module 1 includes: a water level and flow monitoring unit 5, a dam bag monitoring unit 6, a management monitoring unit 7, and a water affairs monitoring unit 8. The water level and flow monitoring unit 5 is used to monitor: water level exceeding the design water level 9, water level exceeding the flood limit water level 10, overflow depth exceeding the limit 11, and flow rate exceeding the design flow rate 12. The dam bag monitoring unit 6 is used to monitor: dam height exceeding the design dam height 13, dam bag internal pressure exceeding the limit 14, automatic dam collapse 15, dam bag vibration 16, and dam bag reverse water blocking 17. The management monitoring unit 7 is used to monitor: flooding 18, fire 19, explosion 20, electric shock 21, lightning strike 22, fall 23, mechanical attack 24, power outage 25, and other events that threaten personal and property safety. The water monitoring unit 8 is used to monitor: rubber dam filling and water storage 26 and dam collapse and water discharge 27, drowning of personnel and submersion of equipment 28, dam failure 29, and external intrusion 30.

[0034] The intelligent control and analysis module 2 is a computer device with calculation, fitting, image recognition, and analysis functions. When it receives a safety issue detected by the monitoring module 1, it processes data, performs simulation analysis, executes control decisions, generates early warning information, and issues the warning to the public through the early warning module device. This module includes: a data processing and analysis unit 31, a storage unit 32, and a control execution unit 33. The data processing and analysis unit 31 is used for identifying and analyzing safety issues 34, processing data 35, and establishing a visualization model 36 to assist management personnel in analysis and decision-making. The storage unit 32 is mainly used to store safety issue data information 37 detected by the monitoring module 1, establish a big data database 38, and provide the data processing and analysis unit with the necessary information 39. The control execution unit 33 is used for intelligent control of the rubber dam filling 40, dam collapse 41, intelligent power outage 42, dialing rescue calls 43, generating early warning information 44, and controlling the early warning module to issue early warning information 45.

[0035] After receiving the early warning information generated by the intelligent control and analysis module 2, the early warning module 3 performs classified early warning and dual-mode early warning. Classified early warning categorizes the target audience into two groups: engineering management personnel and the general public. Different early warning information and modes are developed for each group based on their specific needs. Dual-mode early warning includes two types of units: the on-site early warning unit 46 and the beyond-line-of-sight communication early warning unit 47. The on-site early warning unit 46 uses various devices and equipment, such as voice alarms 48, early warning broadcasts 49, strobe lights 50, large monitoring screens 51, flood discharge electronic screens 52, warning signs 53, and mobile early warning vehicles 54, to issue safety warnings to the surrounding area. The beyond-line-of-sight communication early warning unit 47 uses various media and methods, such as telephones 55, SMS messages 56, WeChat 57, websites 58, mobile clients 59, and WeChat official accounts 60, to issue beyond-line-of-sight safety warnings. Classified early warning and dual-mode early warning complement each other, achieving full coverage of safety warning information to the target audience.

[0036] The system management module 4 mainly consists of a computer terminal 61 and a mobile terminal 62, serving as the system's user management terminal. It provides users with an interactive interface and data display, enabling system function calls, management, and data output. It is used for system parameter settings, system information entry, system upgrades, and other system management tasks. This module includes units such as a panoramic monitoring map 63, real-time monitoring data 64, data analysis and retrieval 65, monitoring and early warning management 66, and system function control 67. Furthermore, a visualization model unit 68 can be established as needed to assist management personnel 70 in analysis and decision-making.

[0037] like Figure 1-6 As shown, the specific operating procedure of the intelligent early warning system for rubber dam safety management is as follows.

[0038] Procedure 1: The sensors and image recognition devices connected to the four monitoring units in the monitoring module 1—water level and flow monitoring unit 5, dam bag monitoring unit 6, management monitoring unit 7, and water affairs monitoring unit 8—conduct routine monitoring of various hazards of the rubber dam.

[0039] Procedure 2: The monitoring module 1 transmits the monitoring data to the intelligent control and analysis module 2, which then processes and simulates the data to determine whether there is an unsafe condition in the hazard source. As needed, a visualization model is established to assist the management personnel 70 in making analysis and decisions.

[0040] Procedure 3: After the early warning system identifies an unsafe state of a hazard source, it feeds back to the engineering management personnel 70. The intelligent control and analysis module 2 generates early warning information and sends an early warning command to the early warning module 3.

[0041] Procedure 4: After receiving the warning command, the early warning module 3 uses multiple media, including the on-site early warning unit 46 and the beyond-line-of-sight communication early warning unit 47, to send warning information to the public 69 and management personnel 70, who are also at risk. If the management personnel 70 do not receive the warning information in time, the early warning system can intelligently take action, such as filling or collapsing the dam, cutting off the power supply, or making emergency calls.

[0042] The following describes examples 1-4 and appendices. Figure 2 Appendix Figure 6 The present invention will be further described.

[0043] Example 1: Water level and flow monitoring and alarm

[0044] (1) The water level exceeds the design water level by 9.

[0045] When the early warning system detects that the water level at the rubber dam exceeds the design water level by 9, it issues an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically lower the dam height to adjust the water level below the design water level. A certain period before automatically lowering the dam height to release water, the early warning system will automatically issue a water release warning to the audience 69.

[0046] (2) The water level exceeds the flood limit level by 10 meters.

[0047] When the early warning system detects that the water level at the rubber dam exceeds the current flood control limit by 10, it issues an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically lower the dam height to adjust the water level below the current flood control limit. A certain period before automatically lowering the dam height to release water, the early warning system will automatically issue a water release warning to the audience 69.

[0048] (3) Overflow depth exceeds the limit by 11.

[0049] When the early warning system detects that the overflow water depth of the rubber dam exceeds the limit of 11, it issues an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically lower the dam height to adjust the overflow water depth below the limit. A certain period before automatically lowering the dam height to release water, the early warning system will automatically issue a water release warning to the audience 69.

[0050] (4) The flow rate over the dam exceeds the design flow rate by 12%.

[0051] When the early warning system detects that the flow rate over the rubber dam exceeds the design flow rate by 12%, it sends an alarm to the management personnel (70) and automatically issues a flood warning to the public (69).

[0052] Example 2: Dam Bag Monitoring and Alarm

[0053] (1) The height of the dam bag is 13 meters above the ground.

[0054] When the early warning system detects that the height of the rubber dam exceeds the design height by 13, it issues an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically reduce the dam height to ensure that the dam height does not exceed the design height.

[0055] (2) The pressure inside the dam bag exceeded the pressure by 14.

[0056] When the early warning system detects that the overpressure overflow pipe of the rubber dam is leaking water, or that the overpressure overflow pipe is blocked and the pressure inside the dam bag exceeds the limit of 14, it will issue an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically reduce the dam height by a certain amount to ensure that the overpressure overflow pipe does not leak water and the pressure inside the dam bag does not exceed the limit.

[0057] (3) Automatic dam collapse 15

[0058] When the early warning system detects that the rubber dam is collapsing automatically due to leakage in the dam bag or pipeline, it will issue an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically fill the dam bag with water to maintain the dam height.

[0059] (4) Dam bag vibration 16

[0060] When the early warning system detects vibration of the dam bag (16), it issues an alarm to the management personnel (70). If the management personnel (70) fails to make adjustments within the specified time, the early warning system will automatically adjust the dam height to prevent the dam bag from vibrating.

[0061] (5) Dam bag reverses water blocking 17

[0062] When the early warning system detects that the water level downstream of the rubber dam exceeds the water level upstream and the dam bag is blocking water in reverse for 17 seconds, it will issue an alarm to the management personnel 70. If the management personnel 70 fails to make adjustments within the specified time, the early warning system will automatically lower the dam height to adjust the upstream and downstream river water until the upstream and downstream water levels are equal.

[0063] Example 3: Management Monitoring and Alerts

[0064] (1) Flood inundation 18

[0065] When the early warning system detects and identifies a flood inundation or deep water accumulation in the rubber dam management area, it issues an alarm to the management personnel 70. If the management personnel 70 fails to handle the situation within the specified time, the early warning system will automatically dial a rescue hotline.

[0066] (2) Fire 19

[0067] After the early warning system detects and identifies a fire within the rubber dam management area, it issues an alarm to the audience 69. If the management personnel 70 fail to handle the situation within the specified time, the early warning system will automatically dial the fire department.

[0068] (3) Explosion 20

[0069] The early warning system will issue an alarm after detecting and identifying an explosion within the rubber dam management area. If the management personnel fail to handle the situation within the specified time, the early warning system will automatically dial a rescue hotline.

[0070] (4) Electric shock 21

[0071] After the early warning system detects and identifies an electric shock 21 that occurs within the management area of ​​the rubber dam, it sends a distress alarm to the surrounding public 69 and management personnel 70. If the management personnel 7 fails to handle the situation within the specified time, the early warning system will automatically dial the emergency number.

[0072] (5) Lightning strike 22

[0073] After the early warning system detects and identifies a lightning strike 22 within the management area of ​​the rubber dam, it issues an alarm to the management personnel 70.

[0074] (6) Falling 23

[0075] After the early warning system detects and identifies a person falling into a place with fall risk within the rubber dam management area, it issues an alarm to the management personnel 70. If the management personnel 70 fails to handle the situation within the specified time, the early warning system will automatically call the emergency medical services.

[0076] (7) Mechanical Strike 24

[0077] After the early warning system detects and identifies a mechanical impact 24 within the rubber dam management area, it issues an alarm to the management personnel 70. If the management personnel 70 fails to handle the situation within the specified time, the early warning system will automatically call an emergency medical service.

[0078] (8) Power outage 25

[0079] After the early warning system detects and identifies a power outage 25 in the power distribution equipment, it issues an alarm to the management personnel 70. If the management personnel 70 fails to handle the situation within the specified time, the early warning system will automatically activate the emergency backup power supply to provide power.

[0080] Example 4: Water Monitoring and Alarms

[0081] (1) Rubber dam filling and water storage 26

[0082] The early warning system must issue a water level rise warning to the public in the affected area 26 days before the dam is filled and water is impounded, reminding citizens not to fish, swim, wash clothes, or carry out construction work in the dangerous areas upstream and downstream of the rubber dam.

[0083] (2) Rubber dam collapse and water spillage 27

[0084] The early warning system should issue a water release warning to the public in the affected area 27 days before the dam collapses and releases water, reminding citizens 69 not to fish, swim, wash clothes, or carry out construction work in the dangerous areas upstream and downstream of the rubber dam.

[0085] (3) Drowning of personnel and submersion of equipment 28

[0086] Early Warning Item 1: When the early warning system detects a drowning incident 28 in the warning zone, it sends a distress alert to the general public 69 and management personnel 70 in the surrounding area.

[0087] Early Warning Item 2: When the early warning system detects an event of flooding of engineering, equipment, or facilities in the monitoring area, it issues an evacuation alarm to the audience, requiring them to dismantle or evacuate in a timely manner, and reports to the management personnel.

3. The intelligent early warning system for rubber dam safety management according to claim 1, characterized in that, After receiving the early warning information generated by the intelligent control and analysis module, the early warning module performs categorized early warning and dual-mode early warning. Categorized early warning divides the target audience into two categories: engineering management personnel and the general public. Different early warning messages and modes are developed for each category based on their specific needs. Dual-mode early warning includes two types of units: on-site early warning units and beyond-line-of-sight communication early warning units. On-site early warning units use various devices and equipment, such as voice sirens, early warning broadcasts, strobe lights, large monitoring screens, flood discharge electronic screens, warning signs, and mobile early warning vehicles, to issue safety warnings to the surrounding area. Beyond-line-of-sight communication early warning units utilize various media and methods, including telephone, SMS, WeChat, websites, mobile clients, and WeChat official accounts, to issue beyond-line-of-sight safety warnings. Categorized early warning and dual-mode early warning complement each other, achieving full coverage of safety early warning information to the target audience.
