Description
Technical Field
[0001] This application relates to the field of safety management technology, and more specifically, to a dam area security system. Background Technology
[0002] With the continuous improvement of the construction and management level of water conservancy facilities, the safe operation of dam areas, as key infrastructure, is of great importance. At present, such areas usually adopt security measures based on traditional monitoring equipment, including the deployment of turnstiles, access control systems and video surveillance equipment at entrances and exits to control the entry and exit of personnel and vehicles and verify their identities; fixed cameras are widely installed inside the dam area, supplemented by some perimeter security alarm devices.
[0003] However, existing systems are primarily characterized by passive monitoring, with video data mostly used for post-incident tracing, lacking the ability to proactively identify and warn of security incidents. Access control and turnstiles can only achieve preliminary control of entry and exit; once personnel or vehicles enter the dam area, the system struggles to continuously and in real-time monitor their activity trajectories and behavioral status. This is especially problematic for critical areas such as riverside areas, core equipment rooms, and construction restricted zones, where external personnel can still easily approach even with access privileges, posing significant security risks.
[0004] Therefore, existing technologies are clearly insufficient in terms of the refinement, intelligence, and comprehensiveness of management. There is an urgent need to build a dam area security system with a high degree of integration, strong intelligent analysis capabilities, and good scalability to improve the overall level of security and prevention.

[0026] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a dam area security system, which aims to solve the problems of poor integration and scalability of the existing dam area security system and the existence of safety hazards.
[0027] Please refer to Figure 1 , Figure 1 This application illustrates a dam area security system according to an embodiment of the present application. The system includes a video surveillance unit, an access control unit, a road vehicle tracking unit, an alarm broadcasting unit, and a central control unit. The outputs of the video surveillance unit, the access control unit, and the road vehicle tracking unit are all connected to the input of the central control unit, and the input of the alarm broadcast unit is connected to the control output of the central control unit. The video monitoring unit includes video monitoring devices distributed in multiple locations within the dam area, and the output of the video monitoring devices is connected to the first video signal input of the central control unit. The access control unit includes at least one vehicle access control device and at least one pedestrian access control device. The vehicle access control device is installed at the vehicle entrance and exit of the dam area and / or the vehicle entrance and exit of a preset area within the dam area. The pedestrian access control device is installed at the pedestrian entrance and exit of the dam area and / or the entrance and exit of a preset area within the dam area. The signal output terminal of the vehicle access control device is connected to the vehicle access control signal input terminal of the central control unit, and the signal output terminal of the pedestrian access control device is connected to the pedestrian access control signal input terminal of the central control unit. The road vehicle tracking unit includes multiple vehicle camera devices installed on roads inside and outside the dam area, and the output terminals of the multiple vehicle camera devices are all connected to the second video signal input terminal of the central control unit; The alarm broadcast unit includes at least one broadcast device, and the input terminals of the broadcast device are all connected to the control output terminals of the central control unit.
[0028] This application aims to achieve efficient management of personnel and vehicles in the dam area, as well as real-time monitoring and early warning of safety conditions. The system consists of a video surveillance unit, an access control unit, a road vehicle tracking unit, an alarm broadcasting unit, and a central control unit. Each unit is communicatively connected to the central control unit and works collaboratively.
[0029] The video surveillance unit deploys monitoring devices at multiple locations within the dam area, covering both inside and outside the dam area and the buildings, capturing dynamic information from all angles. The access control unit is equipped with vehicle and pedestrian access control devices, located at vehicle and pedestrian entrances and exits both inside and outside the dam area, as well as entrances and exits in pre-defined areas within the dam area, collecting entry and exit information and transmitting it to the central control unit. The road vehicle tracking unit deploys vehicle cameras on roads inside and outside the dam area, recording vehicle driving status and license plate information, and providing real-time feedback to the central control unit. The alarm broadcast unit installs broadcast devices in key areas around and within the dam area, issuing broadcast alerts in emergencies.
[0030] The central control unit receives data from each unit, processes and visualizes it, and sends instructions to relevant units to achieve unified management. Through the interconnection and collaboration of multiple modules, this system improves dam area management, optimizes traffic efficiency, provides real-time warnings of potential safety hazards, and ensures the safe operation of the dam area.
[0031] Figure 2 A schematic diagram of the central control unit is shown. The central control unit includes a receiver, a server, a processor, a transmitter, and a display device. The receiver communicates with the server, and the server, transmitter, and display device all communicate with the processor. The video surveillance unit, access control unit, road vehicle tracking unit, and alarm broadcasting unit communicate with the central control unit through receivers and transmitters.
[0032] The receiver and server communicate efficiently and stably, enabling rapid reception of data from video surveillance units, access control units, road vehicle tracking units, and alarm broadcasting units. The server, transmitter, and display device are all connected to the processor. The processor processes the data received from the server and, based on the processing results, sends control signals to other functional units via the transmitter. Simultaneously, it transmits the processed data to the display device for visual presentation, achieving centralized monitoring and unified management of the dam area security system. The video surveillance unit, access control unit, road vehicle tracking unit, and alarm broadcasting unit maintain bidirectional communication with the central control unit through the receiver and transmitter, ensuring information exchange and collaborative operation among the various functional units within the system.
[0033] The server is located in a server room within the dam area. This server room provides a stable operating environment, including suitable temperature and humidity control, as well as excellent electromagnetic shielding and physical security protection. Placing the server here ensures stable operation, reduces the risk of data loss or system failure due to external environmental interference, and also facilitates cabling connections with other functional units within the dam area, guaranteeing stable and efficient data transmission.
[0034] When certain preset behaviors are detected by internal devices such as video surveillance units, access control units, and road vehicle tracking units, such as illegal fishing near the dam area, the core computer room, or construction restricted areas, or traffic violations, the aforementioned broadcasting devices can trigger a warning sound and can link with nearby cameras to view the video footage of 15 seconds before and after the alarm event.
[0035] This application utilizes newly added high-definition capture cameras in key controlled areas to provide front-end image acquisition for functions such as vehicle and pedestrian surveillance, integrated retrieval, traffic incident monitoring, illegal fishing identification, and bridge edge personnel management. A central control unit provides back-end support for these functions. The video surveillance devices in this application must be reliable, technologically mature, and feature-complete distributed structures with flexible system configuration, convenient operation, and a reasonable layout, capable of meeting the requirements for long-term operation. Each device should be reliable, stable, simple in structure, and easy to debug, maintain, replace, and expand in the future.
[0036] The display device includes one or more of the following: a mobile terminal display screen, a non-mobile display screen, and a non-mobile video wall, and all of them are communicatively connected to a processor.
[0037] The display system employs diverse display formats, encompassing mobile terminal displays, non-mobile displays, and non-mobile video walls. Mobile terminal displays, such as smartphone or tablet screens, leverage their portability to enable managers to monitor the dam area's dynamics anytime, anywhere, and receive real-time key information pushed by the central control unit, including personnel entry and exit records and vehicle violation alarms, greatly enhancing management flexibility and real-time response capabilities. Non-mobile displays are stably deployed in fixed locations such as management offices and monitoring centers, continuously and intuitively displaying the overall operational status of the dam area, providing stable visual support for daily monitoring. The non-mobile video wall, with its ultra-large screen and rich content, comprehensively displays monitoring footage and detailed statistical data from various areas of the dam area.
[0038] In one possible embodiment, the central control unit can initially summarize the information received by the video surveillance unit, the access control unit, and the road vehicle tracking unit to form an overview of traffic in the dam area. This overview displays key data such as the total number of people, employees and visitors, and vehicles in real time, and presents the passage records of personnel and vehicles. The system integrates the vehicle gates managed by the dam area security system into the platform, enabling basic functions such as personnel and vehicle information entry, remote gate opening and closing, and vehicle passage record query. It is seamlessly compatible with existing gate equipment, achieving unified management and permission distribution. Vehicle access permissions are managed based on the gate permission mechanism of the checkpoints, effectively controlling vehicle entry and exit from the dam area and its internal passable areas. Users can view the specific vehicle's access permission range and historical authorization records. Management personnel can remotely control gates, retractable gates, and other equipment through the system, supporting various commands such as open, close, normally open, and normally closed.
[0039] For personnel access management, the system maintains basic information about staff, including names, ID numbers, and facial photos, and issues access permissions to access control terminals as needed. Administrators can configure permissions for individuals or groups of personnel through an authorization wizard, associating them with time schedules, door status, door groups, and specific access channels. The system will automatically synchronize personnel data to designated devices and record authorization details, including access point, authorization time, and validity period. For external personnel such as visitors or external partners, an expiration date can be set for permissions; after the expiration date, their facial recognition access function will automatically expire.
[0040] In addition, the system supports a variety of advanced access control functions, such as: first-card access, which allows others to pass only after a specific person has verified their card; multi-card access, which requires multiple specific people to verify their cards in sequence before the door can be opened; multi-door interlock, which allows another door to be opened only after one door is closed; anti-passback function, which forces people to enter and exit in a preset door group order; and remote verification, which requires the management center to review the video footage and confirm the release after the person verifies their card at the terminal.
[0041] The central control unit can also integrate GIS and monitoring data to present access control status in real time, record the passage data of personnel and vehicles within the dam area, and support multi-dimensional retrieval and export by personnel name, license plate, location, time, and other dimensions. Vehicle passage records include real-time data such as time, license plate, and captured images, and can be queried by linking to the gate monitoring video. The system can also achieve comprehensive vehicle tracking and management, providing functions such as blacklist comparison, section speed measurement, vehicle passage recording, and checkpoint alarms based on camera devices, effectively regulating vehicle driving behavior. Blacklist comparison is performed in real time, and an alarm is triggered upon detection of a match; checkpoint speed measurement equipment automatically records speeding events; at the same time, the system can identify abnormal behaviors such as driving in the wrong direction, crossing the line, and illegal parking and generate event messages to notify relevant personnel for timely handling.
[0042] The video surveillance device includes one or more of a face recognition camera, an infrared thermal imaging camera, and / or a video recording camera, all of which are connected to the first video signal input terminal of the central control unit. The video surveillance device also includes a support assembly that connects to the camera.
[0043] Facial recognition cameras are primarily used to collect facial images of personnel entering and exiting the dam area, as well as those active within it. Utilizing advanced facial recognition algorithms, they enable rapid identification and verification of individuals, and can be used for access control, personnel activity tracking, and other scenarios, effectively improving the security and efficiency of personnel management. Infrared thermal imaging cameras are suitable for monitoring tasks in low-light or inclement weather conditions, clearly monitoring the activities of people and objects. For example, at night or in foggy weather, they can promptly detect abnormal heat sources within the dam area, such as fire hazards or unauthorized intrusions. Video recording cameras are used to record dynamic video of personnel within the dam area, providing detailed image data for subsequent event tracing and analysis.
[0044] In addition, the video surveillance device also includes a support assembly that connects to the camera. The support assembly is designed to provide a stable mounting and adjustment for the camera, allowing for flexible adjustment of the camera's shooting angle and height according to different installation environments and monitoring needs. For example, at the entrances and exits of the dam area, the support assembly can mount the camera at a suitable height to capture a complete view of people and vehicles entering and exiting; in important areas within the dam area, such as warehouses and equipment rooms, the support assembly can adjust the camera to the optimal monitoring angle, achieving comprehensive monitoring without blind spots.
[0045] The vehicle camera device includes one or more of the following: violation capture camera, illegal parking capture camera, checkpoint monitoring camera, test camera, mobile camera, video camera, infrared camera, and laser camera, and all of them are connected to the second video signal input terminal of the central control unit.
[0046] The vehicle camera system integrates multiple high-performance cameras to meet the complex vehicle monitoring needs of the dam area. Specifically, it includes at least one of the following: traffic violation capture cameras, illegal parking capture cameras, checkpoint monitoring cameras, test cameras, mobile cameras, video cameras, infrared cameras, and laser cameras. Traffic violation capture cameras utilize advanced image recognition technology to accurately capture vehicle violations such as running red lights, speeding, and crossing lines, automatically recording photos and videos of violations to provide crucial evidence for traffic management. Illegal parking capture cameras focus on monitoring illegal parking within the dam area, immediately capturing and recording images once a vehicle is found to be parked in a no-parking zone for an extended period. Checkpoint monitoring cameras are deployed at the main entrances and exits of the dam area to capture and record images of vehicles entering and exiting in real time, quickly verifying vehicle identity using license plate recognition technology for efficient vehicle access management. Test cameras are used to perform performance testing and parameter optimization on newly installed camera devices to ensure stable operation. Mobile cameras can be installed on patrol vehicles, moving with the vehicle to dynamically monitor different areas within the dam area, effectively filling the monitoring blind spots of fixed cameras. Video cameras are responsible for recording vehicle trajectories and surrounding environment videos over extended periods. Infrared cameras utilize the principle of infrared imaging to capture clear vehicle images at night or in low-light conditions, ensuring uninterrupted monitoring. Laser cameras, with their longer shooting distance and higher resolution, are suitable for vehicle monitoring in distant areas surrounding the dam area.
[0047] In addition, the vehicle camera system is equipped with a variety of support components connected to the camera, designed according to different installation locations and functional requirements. On gates inside and outside the dam area, the support components employ a lightweight and flexible installation method to fix the camera in a suitable position and monitor vehicles entering and exiting; when installed on vehicles, they have shock-resistant and angle-adjustable functions to ensure stable shooting while in motion; ground installations are designed as sturdy pillars to achieve all-round ground vehicle monitoring; when installed on buildings or inside structures, customized designs are made according to structural characteristics to ensure secure installation and optimal shooting angles; installations on plants use methods that minimize the impact on growth, such as wrapping or hooking, to achieve concealed monitoring.
[0048] Figure 5 The diagram shows a schematic of the vehicle access control device proposed in an embodiment of this application. The vehicle access control device includes one or more of the following: a vehicle identification component, an access control actuator, a passage control device, an alarm, and a power supply, all of which are connected to the vehicle access control signal input terminal of the central control unit.
[0049] The vehicle access control system comprises a vehicle identification component, an access control actuator, a passage control device, an alarm, and a power supply. The vehicle identification component uses a high-definition camera to capture license plate information and combines it with intelligent algorithms to accurately identify the vehicle, providing a basis for determining access rights. The access control actuator, based on instructions from the passage control device, controls the raising and lowering of the barrier or gate to allow or block vehicles. The passage control device, as the core component, receives vehicle identification information, compares it with access control data in the database, quickly decides whether to allow the vehicle to pass, and sends corresponding instructions to the access control actuator. The alarm sounds an audible and visual alarm when a vehicle lacks access rights, forcibly enters, or license plate recognition fails, alerting management personnel to intervene promptly. The power supply provides electrical support for the stable operation of the entire system.
[0050] Figure 4 The diagram shows a schematic of the pedestrian access control device proposed in an embodiment of this application. The pedestrian access control device includes one or more of the following: an identity recognition component, a door lock actuator, an access control controller, a camera, an alarm, and a power supply, all of which are connected to the pedestrian access control signal input terminal of the central control unit. The identification components include one or more of card readers, scanners, and biometric terminals.
[0051] Identity verification components, including card readers, scanners, and biometric terminals, are used to verify the identity information of people entering and exiting the premises. Card readers can quickly read the information on access cards carried by people; scanners are used to scan electronic credentials such as QR codes or barcodes presented by people; and biometric terminals, such as fingerprint readers, palm print readers, or facial recognition readers, confirm identity by collecting and verifying the unique biometric features of individuals. The access control controller receives the personnel identity information transmitted from the identity verification components and compares it with the pre-stored permission data in the system. If the verification is successful, it sends a command to the door lock actuator to unlock the door, allowing the person to pass; if the verification fails or abnormal intrusion is detected, the alarm will be activated immediately, issuing an alarm signal to alert management personnel. Cameras are responsible for capturing images of people entering and exiting in real time, providing visual record support for subsequent queries and traceability.
[0052] The broadcasting device includes one or more of the following: loudspeaker, power amplifier, FM transmitter, alarm, controller, and power supply, all of which are connected to the control output of the central control unit.
[0053] The various components of the broadcasting system work together to achieve efficient information dissemination and emergency warning functions. The loudspeaker, as the core component for sound output, is responsible for converting audio signals into clearly audible sound, broadcasting important information such as safety tips and announcements to specific areas within the dam area. The power amplifier ensures a significant increase in the power of the audio signal, enabling the sound to cover a wider area and guaranteeing clarity of information transmission even at greater distances. The FM transmitter expands the coverage and flexibility of the broadcasting system, transmitting audio signals to receiving devices at specific frequencies via wireless FM technology, achieving broadcast coverage of remote areas, especially suitable for scenarios with large dam areas and widely distributed populations.
[0054] The alarm system emits a high-decibel sound when it detects abnormal situations or emergencies, quickly attracting attention and providing crucial warning for timely evacuation or response. The controller precisely adjusts parameters such as playback content, playback time, and volume to ensure the orderly and timely delivery of broadcast information. The power supply provides continuous power support for the stable operation of the entire broadcasting system, ensuring that all components maintain normal operation under prolonged, high-intensity working conditions.
[0055] It is worth noting that the protective cover surrounding the broadcasting device provides all-round protection for the internal components, effectively resisting the erosion of natural environmental factors such as rain, dust, wind and sun, while preventing human-caused damage. This greatly improves the durability and reliability of the broadcasting device in harsh outdoor environments, ensuring its stable operation in the complex environment of the dam area.
[0056] The system also includes a protective cover positioned above the video surveillance device and / or vehicle camera.
[0057] Both video surveillance devices and vehicle camera systems are equipped with protective covers. These covers, positioned above the cameras or camcorders, primarily provide comprehensive protection for the equipment. They effectively block dust, rain, sand, and other external debris from corroding the cameras or camcorders, significantly extending their lifespan. In hot weather, the covers also act as heat insulation, preventing performance degradation due to overheating. Furthermore, the design of the covers helps prevent vandalism, enhancing the security of the camera equipment and ensuring its stable operation in various complex environments. Taking cameras as an example... Figure 3 The diagram shows the distribution of the components proposed in the embodiments of this application.
[0058] The power source used by the system includes photovoltaic power and / or wind power.
[0059] Photovoltaic power uses solar panels to convert solar energy into direct current (DC) electricity. When there is ample sunlight, the panels absorb solar energy and convert it into electrical energy, which is stored in the battery bank. When the system needs electricity, it is converted into alternating current (AC) output via an inverter. Wind power uses wind turbines; the blades rotate under the drive of wind to generate electricity, which is also stored in the battery bank for system use. Both types of power are environmentally friendly and renewable, reducing reliance on the traditional power grid. They are particularly suitable for dam areas where grid coverage is difficult or environmental requirements are high. Furthermore, the two can complement each other, ensuring a continuous and stable power supply under different weather conditions and guaranteeing the 24 / 7 operation of the dam area security system.
[0060] In practical applications, when personnel and vehicles enter or exit the dam area, the facial recognition cameras and vehicle recognition cameras in the video surveillance unit are activated. The facial recognition camera captures images of people's faces, transmits the data to the central control unit server, and after processing by the processor, the access control controller drives the door lock actuator to open the door and allow passage. The entire process is recorded in real time by the video recording camera. At the same time, the vehicle recognition camera captures license plate information, which is then recognized and processed by the access control equipment. The access control actuator controls the electric barrier to rise or fall, allowing or denying vehicle passage. During this process, vehicle camera devices such as violation capture cameras and illegal parking capture cameras continuously monitor the vehicle's driving status. Once a violation is identified, it is immediately captured and the data is uploaded to the central control unit.
[0061] Inside the dam area, infrared thermal imaging cameras and other monitoring equipment continuously monitor the entire area. If any abnormality is detected, including unauthorized entry into a restricted area or a potential fire hazard, the alarm broadcast unit controller will immediately activate the loudspeaker to play an alarm upon receiving the signal. Simultaneously, the alarm information will be transmitted to the mobile terminals of relevant personnel via FM transmitters, enabling staff to respond and handle the situation promptly.
[0062] In terms of power supply, the system relies on multiple energy sources working together: during the day when there is sufficient sunlight, photovoltaic power converts solar energy into electrical energy to power the security system, and stores excess electrical energy in the battery pack; when wind conditions are suitable, wind power generates electricity simultaneously. When it is nighttime or when there is insufficient sunlight and wind, the electrical energy stored in the battery pack can be released to ensure the continuous and stable operation of the security system in the barrier area.
[0063] Compared with the prior art, the embodiments of this application have the following beneficial effects: First, it integrates video surveillance, access control and road vehicle tracking units, and uses technologies such as facial recognition, infrared thermal imaging and license plate recognition to achieve precise control of personnel and vehicles in the dam area, greatly improving traffic efficiency and management accuracy.
[0064] Secondly, by utilizing advanced video surveillance equipment and alarm broadcasting units, the safety status of the dam area is monitored in a comprehensive and 24 / 7 manner. In case of any abnormalities, alarms are quickly issued and relevant devices are activated to nip potential safety hazards in the bud and effectively improve the safety of the dam area.
[0065] Third, the use of photovoltaic and wind power reduces reliance on the traditional power grid and decreases carbon emissions, making it particularly suitable for dam areas where the power grid is inconvenient to cover or where environmental protection requirements are high. Simultaneously, the various functional units of the system are closely interconnected and work collaboratively. All data is aggregated at the central control unit, analyzed and processed by the processor, and then visualized on various display devices, improving management efficiency and the scientific basis of decision-making.
[0066] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
