Description

Technical Field

[0001] This invention belongs to the field of nuclear power technology, specifically relating to an intelligent security cabinet for computer storage devices in nuclear power plants. Background Technology

[0002] With the development of information technology, DCS and PLC systems are widely used in nuclear power plant sites. Maintenance sites have a large number of computers, USB drives, hard drives, and other computer equipment, which are used daily. Due to the special nature of nuclear power plant control systems, the borrowing and returning of dedicated laptops and portable storage media used in nuclear power plant site maintenance still relies on traditional manual methods. This is not only wasteful of manpower and inefficient, but also makes it difficult to control potential virus infections caused by unauthorized internet access. Furthermore, it is difficult to perform querying, statistics, and virus removal functions based on the usage of these items. Therefore, it is urgent to reduce the risk of infection of the control system by portable storage media. Summary of the Invention

[0003] To overcome the problems existing in related technologies, an intelligent security cabinet for computer storage devices in nuclear power plants is provided.

[0004] According to one aspect of the present disclosure, an intelligent security cabinet for computer storage equipment in a nuclear power plant is provided. The intelligent security cabinet includes: a storage cabinet display screen, a storage cabinet card reader, a biometric identification device, a server storage area, and an electronic device storage area disposed within a cabinet frame. The electronic device storage area includes: multiple independent optical disc slots, multiple removable media storage areas, and multiple laptop computer storage areas. The electronic devices include optical discs, laptop computers, and removable media.

[0005] Each removable media storage area, laptop storage area and individual optical disc slot is equipped with a protective door panel, and each individual optical disc slot is equipped with a self-locking slot.

[0006] Each mobile media storage area is equipped with a USB interface. Mobile media stored in this area can be connected to the USB interface for charging, identification of the mobile media number, and connection to the server for virus scanning.

[0007] Each laptop storage area is equipped with a power outlet and a USB port. Laptops stored in this area can be charged by connecting to the power outlet and connected to the server via the USB port. This allows the server to identify the laptop's serial number and, if the laptop is running antivirus software, to obtain the antivirus software's status via USB communication.

[0008] Each individual optical disc slot is equipped with a wireless radio frequency identification (RFID) module, which enables the server to identify the number of the inserted optical disc.

[0009] After the card reader of the storage cabinet recognizes the employee card and authenticates the login identity, the server controls the display screen of the storage cabinet to display an interactive interface for borrowing and / or returning the card.

[0010] After the user completes the borrowing or returning procedures through the user interface, the server controls the storage cabinet display to show a secondary confirmation interface. This secondary confirmation interface includes a keypad area and a biometric identification area. After the user is authenticated by the biometric identification device through the secondary confirmation interface, the server executes the borrowing operation corresponding to the borrowing procedure or the returning operation corresponding to the returning procedure.

[0011] In one possible implementation, when the server performs a borrowing operation, it controls the opening of the protective door of the electronic device storage area corresponding to the borrowing procedure, and determines that the electronic device has been taken away if the radio frequency identification module fails to recognize the CD label, the USB connection of the removable medium is removed, or the USB connection of the laptop is removed, and controls the closing of the protective door of the electronic device storage area.

[0012] In one possible implementation, when the server performs a return operation, it controls the opening of the protective door of the electronic device storage area corresponding to the return procedure and obtains the number of the electronic device in the storage area.

[0013] When the server detects that the serial number of the electronic device matches the serial number of the storage area for the electronic device, it confirms that the return is complete and controls the closing of the protective door of the storage area for the electronic device.

[0014] When the server detects that the tag of the electronic device does not match the number of the storage area for the electronic device, it controls the storage cabinet display to show a prompt message indicating that the return has failed.

[0015] In one possible implementation, the server displays the location of the storage area corresponding to each electronic device and the current status of each electronic device through a storage cabinet display screen;

[0016] The current status of electronic devices includes: available for borrowing and unavailable for borrowing. When the current status of an electronic device is unavailable for borrowing, the server controls the protective door of the electronic device storage area to be closed and prohibits the borrowing and returning procedures for the electronic device storage area.

[0017] When an electronic device is currently available for borrowing, the server allows borrowing and returning procedures to be performed on the storage area of ​​that electronic device.

[0018] In one possible implementation, if the battery level and antivirus progress of an electronic device do not meet preset conditions, or if the electronic device is borrowed, the server determines that the current state of the electronic device is unavailable for borrowing.

[0019] The server determines the current status of an electronic device as available for borrowing if the device's battery level and antivirus progress meet preset conditions, or if the device is returned.

[0020] In one possible implementation, the server is able to count and display the borrowing and return time, type and number of the borrowed electronic device for each user;

[0021] For electronic devices with a set return period, the server can also identify electronic devices that have not been returned by the deadline and the corresponding lending users, and send a return reminder message to the terminal associated with the lending user.

[0022] In one possible implementation, the smart security cabinet further includes: one or more temperature and humidity meters;

[0023] One or more temperature and humidity meters are installed inside the smart security cabinet to monitor the temperature and humidity of the smart security cabinet in real time.

[0024] In one possible implementation, the smart security cabinet further includes: an air conditioning equipment storage area;

[0025] The air conditioning equipment storage area is used to install air conditioning equipment, which is used to adjust the temperature and humidity inside the smart security cabinet.

[0026] In one possible implementation, the partitions inside the smart security cabinet are made of perforated metal panels.

[0027] The beneficial effects of this disclosure are as follows:

[0028] 1. Applicability: Radio frequency identification (RFID) technology relies on electromagnetic waves and does not require physical contact between the two parties. This allows it to establish connections and complete communication directly, regardless of dust, fog, plastic, paper, wood, and various obstacles.

[0029] 2. High efficiency: Radio frequency identification (RFID) technology boasts extremely fast read and write speeds, with a typical RFID transmission process usually taking less than 100 milliseconds. High-frequency RFID readers can even simultaneously identify and read the contents of multiple tags, greatly improving information transmission efficiency.

[0030] 3. Uniqueness: Each RFID tag is unique. Through the one-to-one correspondence between RFID tags and items, the subsequent circulation of each item can be clearly tracked.

[0031] 4. Simplicity: RFID tags have a simple structure, high recognition speed, and require simple reading devices. Especially with the increasing prevalence of NFC technology in smartphones, every user's mobile phone will become the simplest RFID reader. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Figure 1 This is a schematic diagram illustrating an intelligent security cabinet for electronic equipment in a nuclear power plant, according to an exemplary embodiment. Figure 1 As shown, the intelligent security cabinet includes: a storage cabinet display screen 2, a storage cabinet card reader 3, a biometric identification device 4, a server storage area 6, and an electronic device storage area, all installed within the cabinet frame. The electronic device storage area includes: multiple independent optical disc slots 8, a removable media storage area 9, and a laptop storage area 10. The electronic devices may include optical discs, removable media, and laptops.

[0039] The server storage area 6 is equipped with a server, which can communicate with the storage cabinet display screen 2, the storage cabinet card reader 3, the biometric identification device 4, and multiple electronic device storage areas;

[0040] Each mobile media storage area 9, laptop storage area 10 and independent optical disc slot 8 is equipped with a protective door panel, and each independent optical disc slot 8 is equipped with a self-locking slot.

[0041] Each mobile media storage area 9 is equipped with a USB interface, and the mobile media stored in this mobile media storage area 9 can be connected to the USB interface for charging, identification of the mobile media number, and connection to the server for virus scanning.

[0042] Each laptop storage area 10 is equipped with a power socket and a USB port. Laptops stored in the laptop storage area 10 can be connected to the power socket for charging and can be connected to the server via the USB port. This allows the server to identify the laptop's serial number and, when the laptop is running antivirus software, to obtain the antivirus status of the antivirus software via USB communication.

[0043] Each independent optical disc slot 8 is equipped with a wireless radio frequency identification module, which enables the server to identify the number of the inserted optical disc through the wireless radio frequency identification module in each independent optical disc slot 8.

[0044] After the storage cabinet card reader 3 recognizes the employee card and completes the login authentication, the server controls the storage cabinet display screen 2 to display an interactive interface for borrowing and / or returning the storage.

[0045] After the user completes the borrowing or returning procedures on the user interface, the server controls the storage cabinet display screen 2 to show a secondary confirmation interface. This secondary confirmation interface includes a keypad area and a biometric identification area. After the user is authenticated by the biometric identification device 4 on the secondary confirmation interface, the server executes the borrowing operation corresponding to the borrowing procedure or the returning operation corresponding to the returning procedure.

[0046] In this disclosure, the radio frequency identification (RFID) module can be represented as a reader transmitting radio frequency energy within a region to form an electromagnetic field, the size of which depends on the transmission power. Within the reader's coverage area, if the tag is passive, it receives the radio frequency signal emitted by the reader and transmits product information stored in its chip using energy obtained from the induced current; if it is active, the tag actively transmits a signal at a specific frequency, the reader reads and decodes the information, and then sends it to a central information system for data processing. The tag can also modify the data stored within it according to the reader's instructions and can communicate with a computer network through an interface.

[0047] A complete Radio Frequency Identification (RFID) system consists of three parts: a reader, an electronic tag, and a data management system. The reader is a device that reads information from the tag or writes information to the tag. Depending on the structure and technology used, the reader can be a read / write device and serves as the information control and processing center of the RFID system. The basic components of a reader typically include: a transceiver antenna, a frequency generator, a phase-locked loop (PLL), a modulation circuit, a microprocessor, a memory, a demodulation circuit, and a peripheral interface. The electronic tag consists of a transceiver antenna, an AC / DC circuit, a demodulation circuit, a logic control circuit, a memory, and a modulation circuit. For example, an electronic tag can be placed on an electronic device. A reader located in the electronic storage area reads the encoded information contained in the electronic tag and transmits it to a server. The server matches the electronic storage area number with the read encoded information to obtain a matching result, thereby identifying whether the electronic device has been correctly placed in the corresponding electronic device storage area.

[0048] In this disclosure, the biometric identification device may be, for example, any of the following modules:

[0049] Fingerprint Recognition Module: The fingerprint recognition process consists of two parts: fingerprint recording and cross-verification. The fingerprint recording process comprises four parts: fingerprint acquisition, fingerprint preprocessing, fingerprint inspection, and fingerprint template acquisition. The cross-verification process includes four parts: fingerprint acquisition, fingerprint preprocessing, fingerprint feature comparison, and matching. Face Recognition Module: The face recognition system includes image acquisition, face localization, image preprocessing, and feature comparison (identity verification or identity lookup). The system input is generally one or a series of face images containing unidentified faces, as well as several known face images or corresponding codes from a face database. The output is a series of similarity scores indicating the identity of the face to be identified.

[0050] In this disclosure, the server's intelligent antivirus technology targets laptops and removable storage media. The server is connected to the power plant's local area network (LAN) and has an antivirus software client installed. After the server identifies that the returned device has been placed in the correct location (server and removable media placed in designated compartments with data and power cables plugged in), if it is removable storage media, the server automatically starts antivirus scanning upon detection. If a laptop is connected, the antivirus software needs to be run on the laptop, and the server obtains the laptop's antivirus progress. The server periodically synchronizes with the LAN's antivirus server and obtains the latest virus definitions. The intelligent antivirus system obtains the antivirus progress of newly connected devices and displays the percentage of antivirus progress for devices in designated storage compartments on the software's main interface.

[0051] In one application example, such as Figure 1As shown, the overall dimensions of the cabinet are 1.2m*2m*0.4m. It has 20 storage areas for laptops (10), 20 storage areas for removable media (9), and 100 independent optical disc slots (8). Laptops and USB flash drives are connected to the server via USB ports for identification and numbering, while optical discs are identified by RFID tags.

[0052] The upper left corner of the storage cabinet features a card reader and a display screen for easy borrowing and returning. The lower left corner houses a server (connected to the local area network for virus database updates). An air conditioning unit is also located in the lower left corner to control temperature and humidity. To ensure effective temperature control, all internal partitions are made of perforated metal. Figure 1 As shown, a thermometer and hygrometer 1 are installed at the top and bottom of the storage cabinet.

[0053] During the identity authentication phase: authorized users can log in by swiping their employee cards (wireless radio frequency) to borrow and return devices. In the borrowing confirmation process, a password, fingerprint, or facial recognition is required for secondary identification to prevent device loss due to borrowing on behalf of others.

[0054] During the device identification phase: Device identification technology is required during device return. When returning optical discs, they must be inserted into the correct disc holder. The disc holder has a built-in radio frequency chip that automatically identifies the disc upon insertion. Once correctly identified, the slot is locked, and the slot is protected by a single glass door. Removable storage media are connected to the storage cabinet's server via USB for virus scanning, and the server identifies the removable media. Laptops are plugged into an outlet inside the cabinet for charging and simultaneously connected to the server via USB. The laptop runs antivirus software, and the server receives the antivirus software's scanning status via USB communication.

[0055] The main interface displayed on the storage cabinet screen lists laptops, USB drives, and CDs according to the cabinet layout. To prevent tools from being lost, all items are stored independently and in fixed locations. Therefore, the positions of each item on the main interface are also fixed. Each item is marked with a color to indicate its current status: gray - borrowed; green - normal status and available for borrowing (device in the correct location + battery level greater than 80% + virus scan progress 100%); red - abnormal status (currently in return status, virus scan incomplete, battery level less than 80%, etc.). If the cabinet door is accidentally closed, items in abnormal status will require waiting (virus scan completion 100%, charging level greater than 80%) or contacting the administrator to forcibly open the cabinet door.

[0056] After identity verification, you can select any item, and in the pop-up window, you can choose to borrow (only green items can be borrowed), return (only gray items can be returned), or query (you can query borrowing records for gray electronic devices to facilitate communication and coordination between people regarding electronic devices), and follow the system prompts to complete the relevant procedures.

[0057] In one possible implementation, for electronic devices with a set return period, the server can also identify overdue electronic devices and the corresponding lending users, and send a return reminder message to the terminal associated with the lending user. In this way, the relevant users can be promptly reminded to return the overdue electronic devices.

[0058] This disclosed intelligent security cabinet is primarily based on radio frequency identification (RFID) technology, supplemented by biometric technology. It features functions such as item storage and retrieval, biometric identification, automatic virus removal, data analysis, and report generation. To meet the needs of smart nuclear power construction, improve the intelligent management level of nuclear power plants, reduce the risk of control systems being infected by mobile storage media, extend the lifespan and information security of various mobile storage media, and meet the requirements of power plant information security construction, this intelligent security cabinet device is specifically designed to improve the efficiency of borrowing and returning dedicated laptops and mobile storage media used in nuclear power plant maintenance. Furthermore, by utilizing a dedicated device to analyze borrowing and virus removal statistics, it can assist maintenance personnel in making decisions regarding mobile storage media procurement and assessing the overall trend of personnel information security behavior.
