Description

Technical Field

[0001] This utility model relates to the field of security technology, and in particular to a security alarm system for secure conference rooms. Background Technology

[0002] In today's society, with the rapid development of information technology and increasingly fierce international competition, the security protection of various confidential information has become crucial. As special venues for important meetings, secure conference rooms require a high level of security and confidentiality.

[0003] Currently, although many secure meeting rooms have implemented basic security measures such as access control systems and surveillance cameras, these traditional methods still have many limitations in dealing with increasingly complex security threats. Traditional access control systems mainly rely on identification technologies such as card swiping, password input, or fingerprint recognition. While these can control personnel entry and exit to a certain extent, they often fail to detect and respond effectively once the access control is breached or personnel enter the meeting room through other means. Although surveillance cameras can record the surrounding area of ​​the meeting room in real time, they typically only provide two-dimensional visual information, which has certain limitations.

[0004] In addition, most existing security alarm systems lack multi-level early warning mechanisms. They often only trigger alarms after an intrusion has already occurred or even caused some damage, making it impossible to warn of potential security threats in advance and putting security prevention work in a very passive position.

[0005] Therefore, in order to effectively solve the above problems and improve the security level of confidential conference rooms, it is urgent to develop a more advanced and reliable security alarm system. Utility Model Content

[0032] In one specific implementation, the number of millimeter-wave radars 2 is set to multiple, and they are deployed in an X-shaped cross configuration on the top of the room door.

[0033] In one specific implementation, the main control lock 4 is also equipped with a dual power supply, which supplies power to each connected device through a power supply port; wherein, the dual power supply includes a main power supply circuit and a main power supply connected to the main power supply circuit, a bypass power supply circuit and a backup power supply connected to the bypass power supply circuit; the main power supply circuit and the bypass power supply circuit are connected in parallel and are connected to the power supply port through a dual power supply switching switch.

[0034] In one specific implementation, the bottom of the main control lock 4 is also fixedly connected to a support column, which is located outside the area of ​​the pressure sensing floor 1.

[0035] In one specific implementation, the main control lock 4 is also equipped with a touch screen, and a fingerprint sensor is also provided below the touch screen; the touch screen and the fingerprint sensor are also connected to the electronic lock on the door via the LoRa wireless communication module, and are used to open the electronic lock according to the password or fingerprint entered on the touch screen.

[0036] In one specific implementation, the receiving device for the supervisor includes at least one of a personal computer, a laptop computer, a smartphone, a tablet computer, and a portable wearable device.

[0037] Based on the above technical solution, the following embodiments are provided.

[0038] First, the system composition and deployment will be explained.

[0039] Pressure-sensing floor 1 is installed at the bottom of the target confidential conference room, using 800mm×800mm floor tiles. Each tile has a built-in piezoelectric thin-film sensor module underneath, with a total of 36 tiles laid (covering the conference room and a 3-meter extended area around it). Its overall size is designed to be 1.2 times the floor area of ​​the conference room to form a first-level warning zone. When a person or object enters the warning zone and steps on the pressure-sensing floor 1, the piezoelectric thin-film sensor converts the pressure change into an electrical signal, which is then transmitted to the main control lock 4 via a built-in wireless transmitter.

[0040] Four millimeter-wave radars 2 are deployed in an X-shaped crisscross pattern on the top of the door, forming a first three-dimensional monitoring network together with the pressure-sensing floor 1, serving as a secondary early warning zone. The millimeter-wave radars 2 use electromagnetic waves in the millimeter-wave band to scan the door area, accurately detecting the movement trajectory, speed, and location information of personnel. When an abnormal person is detected approaching or entering the door area, the millimeter-wave radars 2 transmit a monitoring signal to the main lock 4 via a wireless transmitter.

[0041] The lidar 3 is installed at the top of the outer window, forming a second three-dimensional monitoring network with the pressure-sensing floor 1, thus creating a three-level early warning zone. The lidar 3 emits multiple laser beams, forming an invisible laser barrier in front of the window. When an object passes through the laser barrier, the lidar 3 immediately detects the signal change and transmits the information to the main lock 4 via a wireless transmitter.

[0042] The audible and visual alarm is installed in a prominent position near the entrance of the conference room and is connected to the main control lock 4. When the main control lock 4 receives a monitoring signal from the pressure-sensing floor 1, millimeter-wave radar 2, or lidar 3, it will trigger the audible and visual alarm to emit a high-decibel alarm sound and flashing lights to alert relevant personnel in the conference room.

[0043] The main control lock 4 is the core control device of the entire security alarm system. It contains wireless receivers that pair with the wireless transmitters in the pressure-sensing floor 1, millimeter-wave radar 2, and lidar 3 to receive monitoring signals from each device. The main control lock 4 also contains a LoRa wireless communication module. When it receives a monitoring signal from any device, it triggers an audible and visual alarm and sends corresponding preset information (such as the name of the warning area and the type of abnormal situation) to the receiving device of the supervisor, based on the warning area level.

[0044] The main control lock 4 is equipped with dual power supplies, including a main power supply circuit and a bypass power supply circuit connected to it, as well as a backup power supply connected to the bypass power supply circuit. The main power supply circuit and the bypass power supply circuit are connected in parallel and connected to the power supply port through a dual power supply transfer switch. Under normal circumstances, the main power supply powers all connected devices; when the main power supply fails, the dual power supply transfer switch automatically switches to the backup power supply to ensure the continuous and stable operation of the system.

[0045] The main lock 4 is fixedly connected to the support column at its bottom. The support column is located outside the area of ​​the pressure-sensing floor 1 to ensure the stability and security of the main lock 4. In addition, the main lock 4 is equipped with a touchscreen, and a fingerprint sensor is located below the touchscreen. The touchscreen and fingerprint sensor are connected to the electronic lock on the door via a LoRa wireless communication module. Users can unlock the electronic lock and enter the conference room by entering the correct password on the touchscreen or using the fingerprint sensor for authentication.

[0046] The specific application of the system shown in this embodiment includes the following:

[0047] Routine monitoring:

[0048] When the system is in routine monitoring mode, the pressure-sensing floor 1, millimeter-wave radar 2, and lidar 3 continuously monitor their respective areas. The pressure-sensing floor 1 senses changes in floor pressure in real time, the millimeter-wave radar 2 scans for personnel activity in the doorway area, and the lidar 3 protects the window area. The primary warning zone extends from the floor to the perimeter of the conference room, forming a relatively broad planar warning range. The secondary warning zone, centered on the doorway, forms a three-dimensional monitoring range in space using millimeter-wave radar 2, partially overlapping with the primary warning zone, but with different focus and monitoring areas. The primary warning zone primarily serves as the first line of defense, detecting personnel or objects approaching the conference room in advance; the secondary warning zone, building upon the primary warning, provides more precise and three-dimensional monitoring of the critical area approaching the doorway.

[0049] When a person or object first enters the Level 1 warning zone, the pressure-sensing floor 1 detects a pressure change, triggering a Level 1 warning and alerting the system and relevant personnel to an abnormal approach. If the person does not stop moving and continues towards the door, entering the Level 2 warning zone, the millimeter-wave radar 2 detects the abnormal activity, triggering a Level 2 warning. At this point, the system further amplifies the alarm and sends more detailed warning information to supervisory personnel so that timely measures can be taken to address potential security threats. This two-tiered warning mechanism, through the coordinated operation of different areas and equipment, achieves graded monitoring and early warning of the security situation around the conference room, improving the accuracy and timeliness of security precautions.

[0050] Abnormal conditions triggered:

[0051] When a person or object enters the Level 1 warning zone (the area covered by pressure-sensing floor 1), the sensing module of pressure-sensing floor 1 detects a pressure change and sends a signal to the main control lock 4. Upon receiving the signal, the main control lock 4 first triggers the audible and visual alarm to sound an alarm, and simultaneously transmits the Level 1 warning information to the receiving device of the supervisor via the LoRa wireless communication module.

[0052] If personnel continue to move into the secondary warning zone (the three-dimensional coverage area formed by millimeter-wave radar 2 and pressure-sensing floor 1), millimeter-wave radar 2 detects abnormal personnel activity and sends a signal to the main control lock 4. The main control lock 4 then triggers the audible and visual alarm again and sends a secondary warning message to the supervisory personnel.

[0053] When an object attempts to breach the Level 3 warning zone (the three-dimensional coverage area formed by LiDAR 3 and pressure-sensing floor 1), LiDAR 3 detects a signal change and sends it to the main control lock 4. The main control lock 4 triggers an audible and visual alarm and sends a Level 3 warning message to the supervisory personnel.

[0054] Application example:

[0055] Example 1: Low risk level - accidental entry or unauthorized personnel approaching (Level 1 trigger).

[0056] Scenario description: Unauthorized personnel (such as ordinary employees or visitors) accidentally enter or are unfamiliar with the location of the conference room and inadvertently step into the extended area surrounding the confidential conference room (i.e., the part covered by pressure-sensing floor 1 but extending beyond the actual area of ​​the conference room).

[0057] System Response: Pressure sensor floor 1 detects a pressure change and triggers a Level 1 warning. Upon receiving the signal, main lock 4 triggers an audible and visual alarm, emitting a soft alarm sound, and sends a Level 1 warning message to the receiving device of the monitoring personnel, indicating that unauthorized personnel are approaching. After receiving the information via LoRa, the monitoring personnel can manually verify whether it is a case of mistaken entry and take appropriate measures (such as guiding the person away, issuing a warning, etc.).

[0058] Example 2: Medium danger level - Attempt to illegally enter the meeting room (Level 2 trigger).

[0059] Scenario Description: An intruder (such as an external person or an internal criminal) attempts to illegally enter the secure conference room through the main entrance, steps into the coverage area of ​​the millimeter-wave radar 2 at the top of the door, and continues to move into the conference room.

[0060] System Response: Pressure sensor floor 1 first detects a pressure change (Level 1 warning triggered), but by this time the intruder has already entered the more critical Level 2 warning zone. Millimeter-wave radar 2 detects abnormal personnel activity and, after comprehensive analysis with the signal from pressure sensor floor 1, confirms the intruder's intent to illegally enter, triggering a Level 2 warning. Upon receiving the Level 2 warning signal, the main control lock 4 amplifies the alarm sound and flashing lights of the audible and visual alarms and sends Level 2 warning information to the receiving equipment of the supervisory personnel, reporting the intruder's location. Based on the warning information, the supervisory personnel quickly take countermeasures, such as dispatching security personnel to the scene to stop the intrusion.

[0061] Example 3: High danger level - forcibly breaking through the window to enter (level 3 trigger).

[0062] Scenario Description: An intruder uses extreme measures, such as breaking windows or using tools to climb over them, to enter the secure conference room. At this point, LiDAR 3 detects an abnormal signal in the window area.

[0063] System Response: While pressure-sensing floor 1 and millimeter-wave radar 2 may have triggered warnings in previous stages, the triggering of lidar 3 indicates that an intruder is attempting to or has successfully entered the conference room, posing the highest level of security threat. Upon detecting the signal change, lidar 3 immediately sends a Level 3 warning signal to the main control lock 4. The main control lock 4 triggers the highest level audible and visual alarm, including a high-decibel alarm sound and a continuously flashing bright light, while simultaneously sending a Level 3 warning message to the receiving equipment of the monitoring personnel, reporting the intruder's location. The monitoring personnel immediately initiate emergency response procedures, mobilizing all available resources, including security personnel and police, to quickly proceed to the scene to handle the intrusion and ensure the security of information and equipment within the conference room.

[0064] Emergency Response:

[0065] Upon receiving an alert, supervisory personnel can take timely emergency measures based on the information, such as visiting the site to assess the situation or notifying security personnel. Meanwhile, the system will continuously monitor for anomalies until normal operation is restored.

[0066] In summary, the technical solution of this utility model has the following beneficial effects:

[0067] (I) Multi-level early warning

[0068] By setting different levels of warning zones, the system can issue timely warnings based on the location and severity of the abnormal situation, enabling regulators to respond quickly.

[0069] (II) High Reliability

[0070] By combining multiple sensor technologies, the system's monitoring accuracy and reliability are improved. Meanwhile, the dual-power supply design of the main control lock 4 ensures that the system can still operate normally in the event of a main power failure, guaranteeing system stability.

[0071] (iii) Convenient access control

[0072] The touchscreen and fingerprint sensor on the main lock 4 provide a convenient access control method. Users can open the electronic lock with a password or fingerprint, which improves the convenience and security of the conference room.

[0073] The secure meeting room alarm system in this embodiment can effectively improve the security level of secure meeting rooms and provide strong protection for the confidentiality of important meetings and information.
