Description

Technical Field

[0001] The invention belongs to the technical field of security monitoring, and in particular relates to an intelligent alarm system for a confidential room. Background Art

[0002] With the growing demand for information security and confidentiality, the safety of secure rooms, which house important confidential information and items, is paramount. Traditional secure room security systems often have limited functionality, failing to comprehensively and in real time perceive changes in the indoor and outdoor environments. This inadequately provides early warning and response capabilities for various potential dangers. For example, in the event of an unauthorized intrusion, the severity of the attack may not be accurately determined in a timely manner. In the case of fire hazards, untimely smoke monitoring can lead to serious consequences. Furthermore, access control lacks flexible and effective multi-level locking strategies. Therefore, developing an intelligent secure room alarm system that can comprehensively monitor multiple environmental factors, intelligently determine the danger level, and implement appropriate and effective measures is of great practical significance. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent alarm system for a confidential room, which can collect real-time and comprehensive environmental information inside and outside the confidential room, intelligently judge abnormal situations and their danger levels, and take corresponding alarm methods and access control measures to improve the security and protection capabilities of the confidential room.

[0004] The technical solutions of the present invention are as follows:

[0005] An intelligent alarm system for a confidential room, comprising:

[0006] Environmental perception module, used to collect real-time information about smoke concentration, vibration signals, temperature and humidity, air pressure, personnel entry signals, and indoor and outdoor images in the confidential room;

[0007] A data processing module is connected to the environment perception module, receives and processes the data collected by the environment perception module, and determines whether there is an abnormal situation and the danger level of the abnormal situation;

[0008] The communication module adopts a multi-link redundant architecture to realize data transmission between the environmental perception module, data processing module, alarm module, and access control module;

[0009] The alarm module receives the alarm information transmitted by the communication module and adopts different alarm methods according to different danger levels;

[0010] The access control module is connected to the data processing module. When a dangerous situation is determined, it will execute a multi-level locking strategy and feedback the real-time access control status.

[0011] The power module provides dual power supply for the entire intelligent alarm system, including mains power supply and backup battery power supply.

[0012] Furthermore, the environmental perception module includes a laser scattering smoke sensor, a vibration sensor, an infrared thermal imaging system, a temperature and humidity sensor, an air pressure sensor, and an image acquisition device, wherein the laser scattering smoke sensor is used to detect indoor smoke; the vibration sensor is installed on the doors, windows, and walls of the confidential room to sense destructive behavior; the infrared thermal imaging system is used to identify the thermal profile of people and abnormal heat sources, and distinguish between living things and inanimate objects; the temperature and humidity sensor is used to monitor indoor temperature and humidity parameters; the air pressure sensor is used to monitor indoor air pressure fluctuations; and the image acquisition device is used to collect indoor and outdoor image information.

[0013] Furthermore, the image acquisition device is a combination of an 8K ultra-high-definition camera and an AI coprocessor, which supports face recognition, liveness detection, object left behind detection, abnormal wandering behavior analysis and multi-angle monitoring. The image acquisition device is connected to the data processing module through a communication module to transmit encrypted image data in real time.

[0014] Furthermore, the data processing module makes a comprehensive judgment through a dynamic risk assessment model to identify abnormal situations of risk levels; specifically:

[0015] When the vibration sensor detection value exceeds the threshold and the infrared thermal imaging simultaneously captures the human body's thermal profile signal, and the camera fails to recognize the authorized face features, the system determines it as a high-risk illegal intrusion event; when the smoke sensor detects that the smoke concentration exceeds the threshold, and the temperature and humidity sensor detects a sudden temperature rise, and the infrared thermal imaging or camera detects open flame features, it is determined to be a high-risk fire accident;

[0016] When the smoke sensor detects that the smoke concentration exceeds the threshold and other sensors do not detect any abnormalities, it is determined to be a medium-risk fire hazard;

[0017] When the image acquisition device continuously detects the same person wandering in a sensitive area without authorized operation, it is determined to be suspicious behavior with a low risk level.

[0018] Furthermore, the alarm module emits a gentle prompt tone and flashes lights through the sound and light alarm for low-risk abnormal situations; for medium-risk situations, in addition to the sound and light alarm, a text message alarm is sent to the mobile phone of the relevant person in charge; for illegal intrusion incidents in high-risk situations, the infrasonic repellent device is activated, 110 is dialed to report the incident and a graphic and text message containing the location is sent, the real-time video stream is pushed to the mobile phones of the police and the relevant person in charge, and the third-level access control lock is triggered simultaneously to block the physical intrusion path; for fire accidents in high-risk situations, the fire alarm is immediately triggered and the sprinkler system is linked, and the real-time video stream is pushed to the mobile phone of the relevant person in charge.

[0019] Furthermore, the power module is powered by the mains and charges the backup battery when the mains is normal, and automatically switches to the backup battery for power supply when the mains is interrupted.

[0020] Furthermore, the access control module integrates biometric verification and multi-level locking strategies, specifically: adopting dual biometric verification technology of vein recognition and 3D structured light face recognition, supporting two-person two-factor authentication mode; executing a multi-level locking strategy when a dangerous situation is determined to exist.

[0021] Furthermore, the multi-level locking strategy includes:

[0022] Level 1 locking: The electric door closer automatically locks to prevent outsiders from entering;

[0023] Secondary locking: The electromagnetic lock is activated, and at the same time, the deformation memory material of the metal door frame is triggered, making the door structure irreversibly locked;

[0024] Level 3 lock: Activate the explosion-proof rolling shutter door to form a secondary physical isolation barrier.

[0025] Furthermore, the environment perception module, data processing module, communication module, alarm module, and access control module are all powered by the power module.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] The present invention can comprehensively and real-timely collect environmental information inside and outside the confidential room through the multiple sensors of the environmental perception module, providing a rich data basis for accurately judging abnormal situations.

[0028] The comprehensive judgment mechanism of the data processing module can intelligently identify abnormal situations of different danger levels, improving the accuracy and pertinence of alarms.

[0029] The alarm module adopts differentiated alarm methods for different danger levels, which enables relevant personnel to quickly understand the severity of the dangerous situation and take corresponding measures.

[0030] The multi-level locking strategy of the access control module enhances the security of the confidential room and effectively prevents outsiders from illegally entering.

[0031] The dual power supply mode of the power module ensures that the system can still operate normally in the event of a mains power outage, improving the stability and reliability of the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The accompanying drawings illustrate various embodiments generally by way of example and not limitation, and together with the description and claims, serve to explain embodiments of the invention. Where appropriate, the same reference numerals are used throughout the drawings to refer to the same or similar parts. Such embodiments are illustrative and are not intended to be exhaustive or exclusive of the embodiments of the present apparatus or method.

[0033] Figure 1 Shown is a system schematic diagram of the present invention. DETAILED DESCRIPTION

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] like Figure 1 As shown, a confidential room intelligent alarm system includes:

[0036] Environmental perception module, used to collect smoke concentration, vibration signals, temperature and humidity, air pressure, personnel thermal profiles, and indoor and outdoor image information in real time;

[0037] A data processing module is connected to the environment perception module, receives and processes the data collected by the environment perception module, and determines whether there is an abnormal situation and the danger level of the abnormal situation;

[0038] The communication module adopts a multi-link redundant architecture to realize data transmission between the environmental perception module, data processing module, alarm module, and access control module;

[0039] The alarm module receives the alarm information transmitted by the communication module and adopts different alarm methods according to different danger levels;

[0040] The access control module is connected to the data processing module. When a dangerous situation is determined, it will execute a multi-level locking strategy and feedback the real-time access control status.

[0041] The power module provides dual power supply for the entire intelligent alarm system, including mains power supply and backup battery power supply.

[0042] The environmental perception module includes:

[0043] High-precision smoke sensors supporting multi-parameter PM2.5 and CO detection were selected. They were evenly installed on the ceiling of the confidential room at a density of 5 to 15 square meters per sensor to ensure no blind spots. During installation, the bottom of the sensor was kept 5 to 10 cm from the ceiling to ensure comprehensive indoor smoke monitoring. Smoke sensors were regularly calibrated and maintained to ensure accuracy.

[0044] The vibration sensor should be installed in a suitable location based on the structural characteristics of the room's doors, windows, and walls. For example, if a piezoelectric vibration sensor is used, install one at each of the four corners and center of the frame of the room's doors and windows. Use strong glue to attach the sensors, and perform a firmness test after the glue cures to ensure they won't fall off even with slight external force. For walls, install the sensors at the center and four corners of each wall, 1 to 2 cm below the wall surface. Drill holes and secure with expansion bolts. Connect the vibration sensor's signal cable to the analog input port of the data processing module. In the data processing module's configuration interface, set the vibration threshold to 0.3g (adjustable based on the actual ambient noise level). When the detected vibration signal exceeds this threshold, the sensor converts the signal into an electrical signal and transmits it to the data processing module.

[0045] High-precision digital temperature and humidity sensors are deployed at a density of three per 100 square meters in the four corners of the secure room and in sensitive equipment areas. These sensors connect to the data processing module via the I2C bus, uploading real-time temperature and humidity data. When the temperature exceeds 28°C or the humidity exceeds 70% RH, the air conditioning system automatically adjusts environmental parameters to prevent equipment failures caused by high temperature and humidity.

[0046] The air pressure sensor uses a MEMS air pressure module and is installed in the center of the top of the confidential room to monitor abnormal fluctuations in indoor air pressure.

[0047] Install the infrared thermal imaging system 2 to 2.5 meters above the entrance to the confidential room, ensuring that the sensor's detection range covers the entire entrance area. During installation, adjust the sensor's detection angle to 15 to 20 degrees from the ground. Debug the infrared thermal imaging system to ensure it can accurately detect people entering and transmit the signal to the data processing module in a timely manner.

[0048] The image acquisition device uses a combination of an 8K ultra-high-definition camera and an AI coprocessor to support face recognition, liveness detection (rejecting photo / video forgeries), detection of left-behind items, analysis of abnormal wandering behavior, and multi-angle 4K / 8K video surveillance. A camera is installed at the door of the confidential room with the lens facing outdoors to monitor the entry and exit of personnel; two cameras are installed in the important item storage area indoors to monitor from different angles. The camera is installed at a height of 2 to 2.5 meters and is fixed to the wall or ceiling with a bracket to ensure that the shooting image is unobstructed. The camera is connected to the local area network where the data processing module is located via a network cable. The image acquisition device is connected to the data processing module through the network to transmit the collected image data in real time.

[0049] The data processing module includes:

[0050] Write a data processing program and set up judgment logic for abnormal situations of different danger levels in the program. For example, when the vibration sensor detection value exceeds the threshold and the infrared thermal imaging simultaneously captures the human body's thermal profile signal, and the camera does not recognize the authorized face features, the system will determine it as an illegal intrusion event with a high danger level; when the smoke sensor detects that the smoke concentration exceeds the threshold, and the temperature and humidity sensor detects a sudden temperature rise, and the infrared thermal imaging or camera detects the characteristics of an open flame, it will be determined as a fire accident with a high danger level;

[0051] When the smoke sensor detects that the smoke concentration exceeds the threshold and other sensors do not detect any abnormalities, it is determined to be a medium-risk fire hazard;

[0052] When the image acquisition device continuously detects the same person wandering in a sensitive area without authorized operation, it is determined to be suspicious behavior with a low risk level.

[0053] The data processing module transmits the judgment results to the alarm module and access control module through the communication module in a timely manner so that corresponding measures can be taken.

[0054] The communication module includes:

[0055] Establish a wired network communication link and use Ethernet to connect the environmental sensing module, data processing module, alarm module, and access control module. Ensure the stability and bandwidth of the Ethernet line to meet data transmission requirements.

[0056] Wireless network communication is also configured, with 4G, 5G, and Wi-Fi modules. In the event of a complex environment or wired network failure, the system automatically switches to the wireless network for data transmission. Wireless network security settings, such as setting a password and enabling encryption protocols, ensure data transmission security.

[0057] The alarm module includes:

[0058] Low-risk level response: Use a mild sound and light alarm (volume ≤ 60dB, light flashing frequency 1Hz), installed in a conspicuous position at the entrance and exit of the confidential room and in the corridor. At the same time, the APP pop-up window will remind and mark the risk location, such as "Unauthorized personnel are detected wandering in sensitive areas."

[0059] Medium-risk level response: Activate a high-decibel sound and light alarm (volume ≥ 100dB), and simultaneously send an alarm message (including risk type, sensor data, and real-time time) to three preset responsible persons via the SMS platform, such as "Smoke concentration exceeds the standard, current value 3.5% obs / m, location: east side of the confidential room."

[0060] High-risk level response:

[0061] Physical expulsion: Triggering an infrasonic expulsion device (frequency 17-19 Hz, sound pressure level 130 dB, non-lethal), with an effective range of 5 meters, forcing the intruder to evacuate;

[0062] External linkage: Automatically dial 110 and send emergency information including GPS location via Beidou short message (e.g. "Illegal intrusion in the confidential room, location: No. XX, XX Road, requesting support");

[0063] Video push: Real-time 8K video stream encryption is transmitted to the police command center and the person in charge's mobile phone app, supporting remote viewing of on-site dynamics;

[0064] Access control linkage: Synchronously trigger the three-level lock of the access control module to block physical intrusion paths.

[0065] The access control module includes:

[0066] Integrated biometric verification and multi-level locking strategy, specifically: dual biometric verification technology using vein recognition and 3D structured light face recognition, supporting two-person two-factor authentication mode; multi-level locking strategy is executed when there is a dangerous situation.

[0067] The first level of locking is achieved through an electric door closer. When the confidential room door is closed, the electric door closer automatically activates and locks the door, preventing outsiders from entering. The electric door closer is connected to the data processing module and can receive control signals from the data processing module.

[0068] During secondary locking, the electromagnetic lock activates, simultaneously triggering the metal door frame's deformation memory material. When the system detects a dangerous situation requiring secondary locking, the data processing module sends a signal to the electromagnetic lock and the metal door frame's deformation memory material control device. The electromagnetic lock generates a strong magnetic force, locking the door securely. The metal door frame's deformation memory material, under the influence of an electric current or other control signal, undergoes irreversible deformation, making the door structure more robust and difficult to damage.

[0069] The explosion-proof rolling shutter door is installed outside the confidential room entrance during a three-level lockout. When a three-level lockout is required, the data processing module activates the explosion-proof rolling shutter door's motor, lowering it to form a secondary physical isolation barrier. Simultaneously, the access control module transmits access lock status information to the data processing module and the relevant personnel's mobile phone, allowing real-time access status monitoring.

[0070] The power module includes:

[0071] The power module provides power to the environmental sensing module, data processing module, communication module, alarm module, and access control module;

[0072] The power module uses a mains power supply and a backup battery. The mains power supply is connected to the mains grid and converts the mains power into the required voltage and current, powering the entire intelligent alarm system. Simultaneously, the mains power supply charges the backup battery, maintaining its charge.

[0073] When the mains power is interrupted, the automatic switching device in the power module quickly switches the power supply from the mains to the backup battery, ensuring that the system can continue to operate normally. Regularly inspect and maintain the backup battery, testing its capacity and performance to ensure reliable power supply during mains power outages.

[0074] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the scope of protection of the present invention.
