Description

Technical Field

[0001] The present invention relates to the technical field of security for thermal power plants, and in particular to an integrated security system for thermal power plants. Background Art

[0002] With energy security becoming increasingly critical, the security systems of thermal power plants, as critical national infrastructure, are crucial. Currently, the security systems commonly used in thermal power plants often utilize independent, decentralized subsystem architectures encompassing modules such as video surveillance, perimeter alarms, access control, and vehicle access control. However, this technical solution has significant drawbacks.

[0003] In terms of system integration, each security subsystem typically operates independently, lacking effective data exchange and linkage mechanisms. For example, the video surveillance system focuses solely on image acquisition and storage, while the access control and vehicle management systems independently perform access control functions. This decentralized architecture prevents these systems from quickly coordinating and responding to security incidents, significantly impacting emergency response efficiency and making it difficult to meet the power plant's real-time prevention and control needs for security threats such as unauthorized intrusions.

[0004] In terms of data transmission and management, the network architecture design of traditional security systems lacks targeted optimization. Some systems rely on a single wired transmission method, which, in complex factory environments, presents wiring difficulties, high maintenance costs, and susceptibility to physical damage. Furthermore, the inconsistent data storage formats across subsystems complicate data analysis and traceability, hindering comprehensive security situational awareness and failing to guarantee the security of the security system itself and data confidentiality.

[0005] To sum up, the traditional thermal power plant security system has many shortcomings such as poor linkage, insufficient accuracy and reliability, and it is difficult to meet the high-level security needs of thermal power plants under the current complex security situation.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] The following combination Figures 1 to 4 The detailed scheme of the comprehensive security system for a thermal power plant provided by an embodiment of the present invention is described.

[0022] Figure 1 It is a structural diagram of the comprehensive security system for a thermal power plant provided by an embodiment of the present invention.

[0023] like Figure 1 As shown, the integrated security system for a thermal power plant provided by an embodiment of the present invention specifically includes: a front-end perception layer 110 , a network transmission layer 120 , a platform management layer 130 and a back-end application layer 140 .

[0024] The front-end perception layer 110 is connected to the network transmission layer 120 , and both the network transmission layer 120 and the back-end application layer 140 are connected to the platform management layer 130 .

[0025] The front-end perception layer 110 is used to conduct comprehensive monitoring of personnel, vehicles, environment and drones within the safety control range of the thermal power plant to obtain comprehensive monitoring data.

[0026] The network transmission layer 120 is used to transmit the comprehensive monitoring data to the platform management layer 130 .

[0027] The platform management layer 130 is used to generate a linkage warning instruction based on abnormal monitoring information in the comprehensive monitoring data after receiving the comprehensive monitoring data, and send the abnormal monitoring information and the linkage warning instruction to the backend application layer 140.

[0028] The backend application layer 140 is used to control the target subsystem related to the linkage warning instruction to cooperate in executing the linkage warning action and display the abnormal monitoring information after receiving the abnormal monitoring information and the linkage warning instruction.

[0029] The system provided in this embodiment, through the multi-level architecture of the front-end perception layer 110, the network transmission layer 120, the platform management layer 130 and the back-end application layer 140, can realize multi-party collaboration in a wireless communication scenario, thereby realizing multi-dimensional and multi-level coordinated security monitoring of thermal power plants, thereby improving the linkage, accuracy and reliability of the security system.

[0030] In one embodiment, the comprehensive monitoring data specifically includes: environmental video data, personnel monitoring data, vehicle monitoring data, and anti-UAV detection data.

[0031] Accordingly, if Figure 2 As shown, the front-end perception layer 110 specifically includes: The video monitoring subsystem 210 is used to collect environmental video data of key security locations in the thermal power plant.

[0032] In this embodiment, key security locations include the factory perimeter, main roads, and key areas. Specifically, one or more high-definition network cameras can be installed in these key security locations. High-definition network cameras offer high resolution, low illumination, and infrared fill light capabilities. In practical applications, these cameras can be encrypted box cameras. These cameras have a maximum image size of 1920×1080, a minimum illumination of 0.001lx for color and 0.0001lx for black and white, and a fill light distance of up to 50m. These cameras can meet monitoring needs in diverse environments and clearly capture detailed information about people and vehicles within them.

[0033] In some embodiments, an independent video surveillance network can be built, with environmental video data collected by HD network cameras transmitted to the platform management layer via access and core layer switches. The platform management layer can implement unified access, centralized management, permission allocation, video and image storage management, video forwarding, decoding and video wall display for HD network cameras, ensuring stable transmission and efficient management of environmental video data.

[0034] In practical applications, the embedded CVR storage mode can be used to store environmental video data for at least 90 days. It also supports personalized settings such as motion detection recording, event recording, and alarm recording, making it easy to record and query different types of events.

[0035] In addition, the platform management layer features a video wall display function, which allows all front-end surveillance images to be displayed on the wall. It supports multiple display modes, including single-channel switching, patrol, splicing, roaming, and windowing. It also supports fast retrieval and video playback, including slow motion, fast forward, single-frame playback, and reverse playback. It also supports playback on the wall and remote download and backup of video files, facilitating analysis and tracing of historical data.

[0036] The access control monitoring subsystem 220 is used to obtain personnel monitoring data at key entrances and exits of the thermal power plant.

[0037] In practice, access control monitoring subsystems can be deployed at key entrances and exits to important areas such as production area entrances and exits, central control rooms, hazardous chemical warehouses, hydrogen supply stations, and monitoring rooms. Specifically, access control devices such as facial recognition access control terminals can be installed. The access control monitoring subsystem integrates multiple recognition methods such as IC or ID card recognition, facial recognition, and password authentication. It can capture and compare facial information in 3D using a binocular camera, effectively filtering out false information such as photos and videos, and improving access control security.

[0038] In some embodiments, the access control and monitoring subsystem can flexibly configure access permissions for individuals, creating a permission table that includes information such as personal information, entry and exit times, restricted areas, and verification methods. Furthermore, the access control and monitoring subsystem features an intercom function, enabling visual communication between front-end personnel and monitoring personnel, allowing monitoring personnel to broadcast messages to the site in a single direction. If a person is unable to open the door for a specific reason, they can call the video surveillance subsystem. The operator compares the image of the person at the card swipe point displayed on the workstation interface with the cardholder's photo to determine whether to allow access.

[0039] The vehicle identification subsystem 230 is used to obtain statistical information about vehicles entering and leaving the parking area of the thermal power plant and obtain vehicle monitoring data.

[0040] In this embodiment, a license plate recognition management system can be installed at the entrances and exits of parking areas as a vehicle identification subsystem. The vehicle identification subsystem specifically includes a camera-screen integrated device, an intelligent vehicle barrier, an ACS entrance and exit management terminal, and auxiliary facilities. The vehicle identification subsystem can automatically identify vehicle license plates, enabling fast, efficient, smooth, and orderly entry and exit of vehicles in parking areas, improving traffic efficiency and reducing loopholes and problems caused by manual operation.

[0041] The anti-UAV subsystem 240 is used to perform abnormal detection on UAVs within the security control range of the thermal power plant and obtain anti-UAV detection data.

[0042] This embodiment features a counter-drone subsystem with drone jamming capabilities, centrally managed by a drone defense management platform. This platform integrates detection modules, countermeasure modules, and various hardware components. The drone defense management platform includes multiple modules, including spectrum detection, radio direction finding, optoelectronic detection and movement management, and countermeasure modules, enabling unified management and interconnected interaction across these modules.

[0043] It should be noted that the transmission power and frequency band of the anti-UAV subsystem comply with relevant national regulations, and during its application, it will not cause harmful interference to important surrounding facilities, nor will it affect the timing of the power system, ensuring the legality and reliability of the UAV monitoring link.

[0044] In one embodiment, the comprehensive monitoring data may further include: perimeter intrusion monitoring data.

[0045] Accordingly, if Figure 2 As shown, the front-end perception layer 110 may further include: The electronic fence subsystem 250 is used to detect whether there is any abnormal intrusion behavior on the set perimeter and obtain perimeter intrusion monitoring data.

[0046] In this embodiment, an electronic fence, such as a pulse electronic fence or a tension electronic fence, can be installed on the perimeter wall of a thermal power plant. The electronic fence consists of an electronic fence host, an electronic fence front end, and an alarm management device. The electronic fence host generates a pulsed high-voltage signal to detect intrusions and issue an alarm. The electronic fence front end includes load-bearing columns, support columns, intermediate columns, and multiple strands of alloy wire, which can block, shock, and deter intruders. The alarm management device transmits alarm signals to the platform management layer and manages these signals.

[0047] In some embodiments, the electronic fence subsystem not only features alarms for tampering, climbing, open circuit, and short circuit, but also includes self-diagnosis, fault alarms, and power outage alarms. If an intruder touches or damages the fence, the electronic fence subsystem will promptly issue an alarm signal. An audible and visual alarm device installed within the perimeter will sound an audible and visual warning to alert nearby personnel. The alarm management device will also receive the alarm information and display the alarm location.

[0048] In one embodiment, the comprehensive monitoring data may further include patrol record data.

[0049] Accordingly, if Figure 2 As shown, the front-end perception layer 110 may further include: The electronic patrol subsystem 260 is used to obtain patrol record data of each patrol point uploaded by the mobile patrol device.

[0050] In this embodiment, the electronic patrol subsystem 260 is implemented based on RFID technology, GPRS mobile communication technology, and cloud data processing technology. The electronic patrol subsystem 260 is composed of target recognition devices, management terminals, and corresponding system software.

[0051] In some embodiments, patrol personnel use handheld inspection equipment or inspection mobile phones that support NFC reading function to sign in and out. After arriving at the designated patrol point according to the planned route, they use the inspection equipment to read the patrol point information. The inspection equipment automatically records the location name and arrival time, and uploads the patrol point information to the platform management level, which can then be sent to the security management center.

[0052] In practice, patrol routes and times can be set and modified based on security management needs, and patrol records are retained for at least 90 days. Platform management can view patrol personnel's inspection status and alarm data in real time through electronic maps. Inspection reports are compiled on a daily, monthly, and annual basis, providing managers with a scientific and effective assessment basis.

[0053] In one embodiment, if Figure 3 As shown, the platform management layer specifically includes: a management server 310.

[0054] The management server 310 is used to: After receiving the comprehensive monitoring data, the target subsystem and linkage warning content in the front-end perception layer are determined based on the abnormal monitoring information in the comprehensive monitoring data.

[0055] Generate linkage warning instructions based on the target subsystem and linkage warning content.

[0056] The abnormal monitoring information and linkage warning instructions are sent to the back-end application layer, so that the back-end application layer controls the target subsystem according to the linkage warning instructions to cooperate in executing the linkage warning action.

[0057] It is understandable that the abnormal monitoring information can be personnel abnormal data, vehicle abnormal data, drone abnormal data, etc. in the comprehensive monitoring data.

[0058] In some embodiments, the management server 310 can also implement functions such as video preview and video playback, support personnel card authority authentication function, implement multiple recognition modes, support batch processing and recording functions of alarm events, as well as the integrated display function of various information such as video screen preview and access control entry and exit information, which can effectively improve the efficiency and accuracy of security management.

[0059] In actual applications, the management server 310 implements functions such as centralized management (such as authority allocation and equipment status monitoring), linkage control (such as alarm triggering multi-system response), data storage (such as classified storage of videos and alarm records), retrieval and playback (such as multi-condition rapid retrieval), and system time synchronization. It can integrate scattered subsystems and has cross-subsystem collaboration capabilities.

[0060] In one embodiment, the management server determines the target subsystem and linkage warning content in the front-end perception layer based on the abnormal monitoring information in the comprehensive monitoring data, specifically including: If the abnormal monitoring information includes personnel abnormal data, the target subsystem in the front-end perception layer is determined to include the target access control monitoring subsystem and the target video monitoring subsystem, and the linkage warning content is determined to include the environmental video data collected by the target video monitoring subsystem during the first target time period corresponding to the personnel abnormal data.

[0061] In this embodiment, the access control monitoring subsystem can send out alarm signals for acts such as forced destruction and illegal entry. For example, when the access control monitoring subsystem detects illegal intrusion (such as forced destruction of access control equipment) or invalid authentication (such as facial comparison failure exceeding the number of times), it can immediately trigger a local alarm. The alarm signal is linked with the video image of the relevant entrance and exit (that is, the environmental video data collected during the first target period). Specifically, the target video monitoring subsystem of the entrance and exit can be linked to record video and capture pictures. At the same time, the platform management end can generate linkage warning content and attach real-time images to facilitate timely detection and handling of abnormal situations.

[0062] In actual applications, the personnel monitoring data of the access control monitoring subsystem shall be stored for no less than 180 days to meet the traceability requirements of security management, and the security level shall not be lower than the Level 2 requirements specified in GB / T37078-2018.

[0063] In one embodiment, the management server determines the target subsystem and linkage warning content in the front-end perception layer based on the abnormal monitoring information in the comprehensive monitoring data, specifically including: If the abnormal monitoring information includes anti-UAV abnormal data, it is determined that the target subsystem in the front-end perception layer includes the target anti-UAV subsystem and the target video surveillance subsystem, and the linkage warning content is determined to include the environmental video data collected by the target video surveillance subsystem in the second target time period corresponding to the anti-UAV abnormal data.

[0064] In this embodiment, when the anti-UAV subsystem detects an abnormal UAV intrusion, it can automatically locate the position of the invading UAV. At this time, the platform management layer can dispatch the target video surveillance subsystem closest to the invading UAV to turn to the area where the invading UAV is located, conduct video tracking, and record the flight trajectory; at the same time, trigger an audible and visual alarm to deter the invading UAV.

[0065] In some embodiments, when the electronic fence subsystem triggers an alarm (such as an open circuit or short circuit in a certain defense zone), the platform management layer can retrieve the environmental video data of the target video surveillance subsystem corresponding to the defense zone, display the video screen on the wall, and synchronously turn on the lights in the alarm area at night to assist the on-duty personnel in confirming the on-site situation, such as whether there is anyone climbing.

[0066] In some embodiments, when an unauthorized vehicle attempts to enter the parking area, the vehicle identification subsystem refuses to let it pass and pushes the vehicle information (such as license plate and photo) to the platform management layer, and links the target video surveillance subsystem to track the vehicle's trajectory. If the vehicle forcibly breaks through the checkpoint, the electronic fence subsystem can trigger an auxiliary alarm.

[0067] In some embodiments, when the patrol personnel read the patrol point through the patrol equipment, the platform management can simultaneously verify whether the current location of the patrol point is consistent with the preset route. If it deviates or the patrol is not on time, a patrol abnormality warning will be triggered; if an abnormality is found during the patrol process, such as an abnormal opening of the access control, it can be reported through the patrol equipment, and the platform management can link with the nearby target video surveillance subsystem to view the scene to confirm whether there is any abnormality.

[0068] In one embodiment, see Figure 3 The platform management layer may further include: a master control terminal 320 .

[0069] The master control terminal 320 is used to display the plant-wide monitoring screen corresponding to the comprehensive monitoring data, and after receiving a screen switching request, switches the plant-wide monitoring screen according to the switching method corresponding to the screen switching request.

[0070] In this embodiment, the monitoring screen of the entire factory area can be displayed in real time through the master control terminal 320, and switching operations such as single channel, patrol, and splicing are supported. In addition, the on-duty personnel can operate through the master control terminal 320 to receive alarm information and dispatch disposal.

[0071] In one embodiment, if Figure 4 As shown, the network transport layer specifically includes: a switch 410 , a firewall 420 and a router 430 .

[0072] The switch 410 is connected to the front-end perception layer, the firewall 420 is connected to the router 430, and the router 430 is connected to the platform management layer.

[0073] The switch 410 is used to aggregate the comprehensive monitoring data and forward it to the firewall 420; the firewall 420 is used to perform security checks on the comprehensive monitoring data and transmit the comprehensive monitoring data that passes the security check to the router 430; the router 430 is used to forward the comprehensive monitoring data that passes the security check to the platform management layer.

[0074] In this embodiment, various data obtained by the front-end perception layer can be transmitted to the platform management layer through the network transmission layer. The switch 410, firewall 420 and router 430 cooperate to ensure the security and real-time synchronization of the data transmission link.

[0075] In one embodiment, the backend application layer specifically includes: at least one user terminal device; The user terminal device is used to send remote control instructions to the target subsystem related to the linkage warning instruction after receiving abnormal monitoring information and linkage warning instructions, so as to control the target subsystem related to the linkage warning instruction to cooperate in executing the linkage warning action.

[0076] The user terminal device is also used to display the abnormal monitoring information in accordance with the display method corresponding to the information viewing request after receiving the information viewing request.

[0077] In this embodiment, managers can view the comprehensive monitoring data obtained by the front-end perception layer anytime and anywhere through user terminal devices to achieve remote monitoring and management. At the same time, remote control can be achieved through user terminal devices, such as remote access unlocking and patrol record viewing.

[0078] In some embodiments, after an abnormal situation is discovered, the system provided by this embodiment also has a multi-level response warning function, which can be implemented as follows: Level 1 response warning: activate on-site sound and light alarms, and link the lights and camera focus in the video surveillance subsystem in the area.

[0079] Level 2 response warning: The platform management pushes warning information to the on-duty personnel terminal. After the on-duty personnel confirm it through video, they remotely control the adjacent access control to lock and close the vehicle barrier to block the intrusion path.

[0080] Level 3 response warning: If a malicious intrusion is confirmed (such as someone carrying weapons), the platform management will connect to the external emergency system (such as the factory security department or public security system) and simultaneously send information such as the location and on-site images.

[0081] In summary, the comprehensive security system for thermal power plants provided by the embodiments of the present invention has at least the following advantages: First, it significantly improves the overall security prevention capabilities of thermal power plants. Through the collaborative work of multiple subsystems, it achieves all-round, multi-level monitoring and protection of the plant area, which can effectively prevent and respond to security threats and ensure the normal production and operation order of the power plant.

[0082] Second, it improves the intelligence level of security management, realizes information sharing and linkage control among subsystems, reduces manual intervention, and improves response speed and processing efficiency.

[0083] Third, the system has complete self-checking and alarm functions, which can detect and handle faults in time to ensure the continuous and effective operation of the security system.

[0084] Fourth, it reduces security management costs. Through automated monitoring and management methods, the workload of manual inspections and operations is reduced, management efficiency is improved, and thus labor costs and operating costs are reduced.
