Description

Technical Field

[0001] This invention relates to the technical field of nuclear power plant main control room management, and more specifically, to an intelligent prevention and control management system and method for nuclear power plant main control room. Background Technology

[0002] As the core area for the safe operation of nuclear facilities, the main control room of a nuclear power plant directly impacts nuclear safety and operational reliability through personnel access management. Existing main control rooms utilize traditional mechanical turnstiles, which only provide basic physical barriers and lack intelligent management mechanisms. Specific shortcomings include: Outdated management methods: Relying on verbal instructions from operators or personnel's self-discipline in following access rules, there are no automated recording and verification methods. This makes it susceptible to human error (such as mistakenly allowing entry or memory bias) leading to unauthorized personnel entering, posing a serious risk of human error. Ineffective management during peak periods: During major overhauls, frequent personnel movement (such as concentrated entry and exit of maintenance, commissioning, and supervision personnel) creates a noisy environment in the main control room. Verbal communication is inefficient and prone to errors. Traditional turnstiles cannot differentiate personnel permissions, hindering precise control and exacerbating chaos and safety hazards in the main control room. Lack of human error prevention: Traditional turnstiles cannot record personnel entry and exit times, frequency, and access permissions, failing to provide data support for post-event tracing and human error analysis, thus not meeting the safety requirements of "defense in depth" and "refined management" for nuclear power plants.

[0003] Meanwhile, in existing technologies, the turnstile systems in civilian locations (such as office buildings and stations) only have basic identity verification functions, which cannot meet the high security requirements of the nuclear power plant's main control room; although the access control systems in some industrial locations support access control, they mostly rely on physical media such as cards, which pose risks of loss and misuse, and are not linked to the real-time authorization process of the nuclear power plant's main control room operators, and cannot meet the refined management and control requirements of the nuclear power plant's main control room.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To address the shortcomings of traditional technologies, this invention provides an intelligent prevention and control management system for the main control room of a nuclear power plant. This system enables automatic identification and hierarchical control of personnel permissions, replacing traditional verbal management and eliminating the risk of misjudgment due to human intervention. For licensed and above key personnel (such as ERO officers, shift leaders, safety engineers, and operators), biometric verification enables rapid self-service access, ensuring efficient response from core personnel. For unlicensed personnel (such as work supervisors), a closed-loop management mechanism of "operator authorization - sensor access" is established to ensure their access is under control. Through automated recording and data integration, it provides data support for personnel flow analysis and human risk early warning in the main control room, improving the scientific nature and traceability of human risk prevention management.

[0019] refer to Figure 1 , Figure 1 This invention illustrates an intelligent security and control management system for the main control room of a nuclear power plant. This system addresses the stringent requirements for "personnel access and control" in the "Regulations for the Safety of Nuclear Power Plant Operations" for the safety management of the main control room of a nuclear power plant. It constructs this intelligent access control system through a collaborative "hardware + software" architecture.

[0020] Specifically, such as Figure 1 As shown, the intelligent prevention and control management system of the main control room of the nuclear power plant includes: a core control unit 101, a face recognition unit 102, an infrared sensing unit 103, a digital control unit 104, and a gate unit 105.

[0021] In this embodiment of the invention, the core control unit 101 is connected to the face recognition unit 102, the infrared sensing unit 103, the digital control unit 104, and the gate unit 105, respectively. It receives signals from each unit and performs logical judgments to control the gate unit 105 to open or close. Specifically, the core control unit 101 is mainly installed on the motherboard. As the core of the system, it receives signals from each unit / module and performs logical judgments (such as permission verification, authorization commands, face recognition, etc.), and controls the gate unit 105 to open or close.

[0022] In this embodiment of the invention, the face recognition unit 102 is used to perform face recognition on personnel entering the main control room of a nuclear power plant.

[0023] In some embodiments, the face recognition unit 102 includes: an infrared binocular camera 1021 and a nuclear-level personnel database 1022; The infrared binocular camera 1021 is used to perform facial recognition on personnel entering the main control room of the nuclear power plant, obtain facial information, and transmit the facial information to the core control unit 101 for rapid verification of the identity of licensed / non-licensed personnel. The nuclear-grade personnel database 1022 is used to store and manage nuclear-grade personnel information of the nuclear power plant. By incorporating the infrared binocular camera 1021 and the nuclear-grade personnel database 1022, this invention can support accurate identification in special scenarios such as wearing safety helmets and glasses, with an accuracy rate of over 99% (≥99.9%), achieving the goal of rapidly verifying the identity of licensed personnel.

[0024] Specifically, this invention, by setting up a facial recognition unit 102 in conjunction with a core control unit 101, for the first time in the field of access management for the main control room of a nuclear power plant, designs a "biometric recognition + hierarchical authorization" mechanism. This mechanism designs differentiated access procedures based on the type of personnel in the main control room of a nuclear power plant (e.g., licensed personnel / non-licensed personnel) to achieve precise control over access permissions. The differentiated access procedures for licensed personnel and non-licensed personnel are as follows: First, precise control is achieved through facial recognition technology. The facial information of license holders is collected, entered, and stored in the nuclear-level personnel database 1022. At the same time, facial recognition authorization is granted to license holders so that they can pass through automatically by scanning their faces in the future. For non-licensed personnel who do not have the relevant authorization, they can pass through by pressing a button only after the operator agrees.

[0025] Secondly, in actual operation, when personnel enter the main control room of the nuclear power plant, their facial information is collected through the facial recognition unit 102.

[0026] Next, the core control unit 101 compares the facial information with the data in the nuclear-level personnel database 1022. If the person is identified as a licensed person, it is determined that they have authorized authority, and the core control unit 101 outputs a control signal to the gate unit 105 to open the gate unit 105, allowing the person to quickly pass through the gate. If the person is identified as an unlicensed person, it is determined that they do not have authorized authority, and the unlicensed person identification information is output and displayed.

[0027] Then, the operator determines that the person is an unlicensed person based on the unlicensed person identification information displayed on the operator authorization terminal 1042. If it is determined that the person can pass, the operator sends an opening command to the gate unit 105 by pressing a button. The gate unit 105 opens according to the opening command, so that the person can pass through the gate. This realizes that unlicensed persons can only pass by pressing a button after obtaining the operator's consent without relevant authorization.

[0028] In this embodiment of the invention, the infrared sensing unit 103 is used to perform infrared sensing detection on personnel entering the infrared sensing area and to trigger a local alarm based on the alarm control signal of the core control unit 101.

[0029] In some embodiments, the infrared sensing unit 103 includes an infrared sensing module and a local alarm module. The infrared sensing module is used to detect personnel entering the infrared sensing area and sends the generated infrared detection signal to the core control unit 101. The local alarm module is connected to the core control unit 101 and is used to trigger a local alarm according to the alarm control signal. Specifically, by setting the infrared sensing unit 103, the present invention can monitor the status of personnel in the gate channel in real time (such as whether there is tailgating or lingering), and trigger a local alarm when abnormal personnel status is detected (such as tailgating or lingering). At the same time, the core control unit 101 controls the gate unit 105 to lock the gate.

[0030] In this embodiment of the invention, the infrared sensing unit 103 is configured to be redundant with the button opening and closing.

[0031] This invention, through the linkage of the facial recognition unit 102, infrared sensing unit 103, and core control unit 101, achieves the following: automatic matching of facial recognition and access permissions for licensed personnel; linkage control logic for "operator authorization-sensor access" for unlicensed personnel; and a real-time feedback mechanism for infrared sensing and gate status. This enables: automatic identity verification and rapid passage for licensed personnel; for unlicensed personnel, the gate only opens after the operator's consent and unlocking button. Simultaneously, utilizing the redundant configuration of the infrared sensing unit 103 and the button opening / closing mechanism, when a licensed person scans their face and approaches the infrared sensing laser (i.e., enters the infrared sensing area), the gate opens automatically. When leaving the main control room, the gate automatically opens when all personnel approach the infrared sensing laser.

[0032] In this embodiment of the invention, the digital control unit 104 is used to manage access control data, automatically store log information, interface with the nuclear power plant safety management system, and execute authorized operations according to the operator's instructions.

[0033] In some embodiments, the digital control unit 104 includes: an access control database 1041, a log recording module 1043, an operator authorization terminal 1042, and a system interface module 1044. The access control database 1041 stores and manages access control data; the log recording module 1043 automatically stores log information; the operator authorization terminal 1042 executes authorized operations according to the operator's commands; and the system interface module 1044 interfaces with the nuclear power plant safety management system. Specifically, by setting up the access control database 1041, access control data, such as personnel job information and authorization levels, can be stored and managed. By setting up the operator authorization terminal 1042 (including a human-machine interface (including a display screen, operation buttons, etc.)), it can support triggering / voice confirmation of unlicensed personnel access requests. By setting up the log recording module 1043, entry and exit times, personnel information, abnormal events, and other log information can be automatically stored. Furthermore, by setting up the system interface module 1044, this invention enables the system to interface with the nuclear power plant safety management system, achieving data sharing. This invention, by interfacing with the nuclear power plant safety management system, enables encrypted storage and traceability of personnel access logs. Specifically, the background data is accessed by the nuclear power plant safety management system, which automatically stores and encrypts personnel access logs, ensuring that all access records are traceable.

[0034] In addition, this invention integrates infrared sensing and digital control to build a fully automated management system of "identification-judgment-execution-recording" to replace traditional manual intervention and reduce the risk of human error. Specifically, when a person enters the infrared sensing area of ​​the gate channel, the infrared sensing system is automatically triggered. Its background software system automatically determines the number of people entering, triggers the gate to open, and records the number of people entering.

[0035] In this embodiment of the invention, the gate unit 105 includes: a gate body 1053, a drive mechanism 1051, and a flexible blocking structure 1052 mounted on the gate body 1053. The drive mechanism 1051 is connected to the core control unit 101 and is used to drive the flexible blocking structure 1052 to open or close according to the drive control signal of the core control unit 101. Preferably, the drive mechanism 1051 is a servo motor; the gate body 1053 is an electromagnetic interference-resistant gate body 1053 structure. Further, the flexible blocking structure 1052 has an automatic unlocking function in emergency situations (such as automatic opening during a fire alarm), taking into account both safety and emergency response requirements. By designing the flexible blocking structure 1052 and adopting a flexible emergency unlocking gate drive method, this invention can ensure the gate operates in a balanced manner in emergency situations, ensuring the safety of personnel entering and exiting and the safety of equipment operation. For example, the gate opening and closing method is a slow and balanced flexible drive method, and the drive mechanism 1051 adopts a design to prevent severe impacts. Therefore, it can ensure the gate operates in a balanced manner in emergency situations, ensuring the safety of personnel entering and exiting and the safety of equipment operation. Meanwhile, the gate body 1053 of the present invention is made of anti-electromagnetic interference material, which can meet the special requirements of the strong electromagnetic environment of nuclear power plants.

[0036] Furthermore, in embodiments of the present invention, such as Figure 1 As shown, the intelligent control and management system for the main control room of the nuclear power plant also includes a power supply module 106 and a signal transmission module 107. The power supply module 106 provides electrical power to the system; the signal transmission module 107 performs encrypted signal / data transmission.

[0037] Preferably, the power module 106 is a dual-redundant power supply circuit used to perform dual-redundant power supply. By employing a dual-redundant power supply circuit, this invention can achieve dual-redundant power supply, ensuring uninterrupted operation.

[0038] Preferably, the signal transmission module 107 uses fiber optic communication for encrypted signal / data transmission. By employing encrypted transmission, this invention ensures the security and reliability of information / data, further enhancing data transmission reliability and improving the information security level of the nuclear power plant.

[0039] This invention utilizes a facial recognition unit 102, an infrared sensing unit 103, and a core control unit 101 for coordinated control. Through biometric identification (preventing impersonation), tiered authorization (strictly controlling access), and real-time monitoring (preventing tailgating), it forms multiple security barriers, meeting the high safety requirements of nuclear facilities. Compared to traditional technologies, this invention offers superior security. Furthermore, this invention employs fully automated management, reducing manual intervention and resolving the inefficiencies and errors associated with verbal management in traditional turnstiles. Compared to traditional technologies, this invention boasts a higher level of intelligence. Designed for the strong electromagnetic environment of nuclear power plants, special attire (such as helmets and protective clothing), and emergency scenarios (such as emergency evacuation), this invention features hardware anti-interference capabilities and flexible software application, making it more adaptable than traditional technologies. This invention can automatically record all data and abnormal events entering and exiting the nuclear power plant's main control room, providing complete evidence for safety audits and human factor analysis. This is superior to traditional methods with no records or manual recording, offering better traceability compared to traditional technologies.

[0040] refer to Figure 2 The present invention also provides an intelligent prevention and control management method for the main control room of a nuclear power plant, which can be applied to the intelligent prevention and control management system for the main control room of a nuclear power plant disclosed in the embodiments of the present invention.

[0041] In this embodiment, such as Figure 2 As shown, the intelligent prevention and control management method for the main control room of this nuclear power plant includes: Step S201: Obtain facial information of personnel entering the main control room of the nuclear power plant.

[0042] Specifically, facial information can be collected by the facial recognition unit 102. When personnel need to enter the main control room of the nuclear power plant through the gate, the facial recognition unit 102 collects their facial information. For example, the infrared binocular camera 1021 can capture images of the person's face, obtain their facial information, and send the facial information to the core control unit 101.

[0043] Step S202: Perform identification and judgment based on facial information.

[0044] In this step, after receiving the facial information sent by the facial recognition unit 102, the core control unit 101 compares and identifies the facial information with the data in the core personnel database 1022.

[0045] Alternatively, in some other embodiments, a face recognition module may be integrated into the face recognition unit 102, and the face recognition module may be used to perform recognition and judgment based on the face information.

[0046] Step S203: If it is determined that the personnel entering have the conditions for hierarchical authorization, then control the gate unit 105 to open.

[0047] Step S204: If it is determined that the personnel entering do not meet the conditions for hierarchical authorization, the gate unit 105 is opened or kept closed according to the operator's operation.

[0048] If the person is identified as a licensed individual, they are deemed to have authorized access (i.e., the person entering has tiered authorization conditions). The core control unit 101 outputs a control signal to the gate unit 105, causing the gate unit 105 to open, allowing the person to quickly pass through the gate. If the person is identified as an unlicensed individual, they are deemed not to have authorized access (i.e., the person entering does not meet the tiered authorization conditions), and the unlicensed individual identification information is output and displayed. The authorized operator, using the operator authorization terminal 1042, determines the person as unlicensed based on the unlicensed individual identification information displayed on the operator authorization terminal 1042. If it is determined that the person can pass, an opening command is sent to the gate unit 105 via a button. The gate unit 105 opens according to the opening command, allowing the person to pass through the gate. This implements the principle that unlicensed individuals, without relevant authorization, must obtain the operator's consent before pressing the button to pass.

[0049] refer to Figure 3 The present invention also provides another embodiment of the intelligent prevention and control management method for the main control room of the nuclear power plant.

[0050] Specifically, such as Figure 3 As shown, the intelligent prevention and control management method for the main control room of this nuclear power plant includes: Step S301: Perform infrared sensing detection on personnel entering the infrared sensing area and generate an infrared detection signal.

[0051] Step S302: Automatically identify and determine the status of personnel entering based on infrared detection signals.

[0052] Step S303: If the status of the personnel entering is normal, record the number of people entering.

[0053] Step S304: If the personnel entering the gate are in an abnormal state, the gate unit 105 will be closed and a local alarm will be triggered.

[0054] The intelligent prevention and control management system and method for nuclear power plant main control rooms provided by this invention can simultaneously meet the requirements of nuclear power plant main control room scenario adaptation, hierarchical access control, real-time authorization linkage, high security and traceability. This invention not only eliminates the risk of misjudgment caused by human intervention, but also ensures the response efficiency of personnel in core positions. For non-licensed personnel, a closed-loop management mechanism of "operator authorization - sensor access" is established to ensure that their entry and exit behavior is within a controllable range. Through automated recording and data integration, it provides data support for main control room personnel flow analysis and human factor risk early warning, improving the scientific nature and traceability of human factor prevention management. Compared with traditional technologies, this invention has higher security, higher intelligence, stronger adaptability, and better traceability.
