Description

Technical Field

[0001] This utility model relates to the field of security, and in particular to a building security monitoring system. Background Technology

[0002] In the construction of security monitoring systems for modern buildings, the rear stairwell area is usually a key monitoring area. However, for the rear stairwells of some existing buildings, especially older buildings, due to factors such as building structure and decoration, re-laying network cables is costly, difficult to construct, and may damage the original structure. Existing wireless transmission technologies have many problems when applied to the relatively enclosed environment of the rear stairwell with many obstacles. For example, the signal is easily attenuated by walls, stairs, etc., resulting in unstable transmission, high packet loss rate, and inability to guarantee the integrity and real-time transmission of monitoring video data, making it difficult to meet the actual needs of security monitoring. Utility Model Content

[0003] To overcome the numerous problems inherent in existing technologies when used in relatively enclosed environments like back staircases with many obstacles—such as signal attenuation due to walls and stairs leading to unstable transmission, high packet loss rates, and inability to guarantee the integrity and real-time transmission of surveillance video data, thus failing to meet the actual needs of security monitoring—this utility model provides a building security monitoring system for security monitoring within building floors, comprising:

[0004] The camera module is equipped with multiple network cameras, with one network camera installed on each floor;

[0005] The wireless transmission module is equipped with multiple wireless gateways. One wireless gateway is installed on each floor. The wireless network is connected to the network camera. The wireless gateways on the upper floors are cascaded with the wireless gateways on the lower floors. A router is installed on the roof. The router has a built-in SIM card and is connected to the wireless gateway on the top floor and the monitoring center.

[0006] The power module is equipped with multiple energy storage battery modules, with one energy storage battery module installed on each floor. The energy storage battery modules are connected to the network cameras and wireless gateways on the corresponding floors.

[0007] Optionally, each floor is equipped with a wireless signal repeater, which is used to amplify and forward wireless signals.

[0008] Optionally, each floor is equipped with a wireless spectrum analyzer, and the wireless gateway is a dual-band gateway, which is connected to the wireless spectrum analyzer.

[0009] Optionally, the power module may also include a power controller, which has a built-in power monitoring unit and a power regulation unit.

[0010] Optionally, the power supply regulation unit includes a power switching circuit, a pulse width modulation circuit, and a power supply voltage regulation circuit.

[0011] Optionally, the energy storage battery modules can be detachably installed in the floor.

[0012] Optionally, the energy storage battery module includes an NFC chip.

[0013] Optionally, the power module also includes an overheat protection circuit, which is connected to the energy storage battery module. The overheat protection circuit includes a temperature sensor, a control chip, and a cut-off switch.

[0016] The beneficial effects of this utility model are: This application realizes the cabling-free deployment of a monitoring system for the rear stairwell area of ​​old buildings. The wireless signal remains stable through short-range multi-hop transmission. For example, in a six-story building, the transmission path is divided into five single-layer penetrations, which improves the signal strength by about 20dB compared to the solution that directly penetrates five floors. The localized power supply system eliminates the need for power line modification, and the failure of a single-layer device does not affect the operation of the overall system. During maintenance, only the energy storage battery module of the corresponding floor needs to be replaced. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Figure 1 This is a structural diagram of the building security monitoring system of this utility model deployed in a building;

[0019] Figure 2 This is a structural block diagram of the new building security monitoring system. Detailed Implementation

[0020] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0021] To address these issues, the design concept revolves around a spatially distributed architecture. To mitigate signal attenuation, the approach involves reducing transmission distance to minimize signal loss and employing layered relay transmission instead of single-point long-distance communication. For power supply challenges, a localized power supply model is proposed to eliminate cable dependency. Through modular design, camera, transmission, and power supply units are integrated into each floor, forming independent subsystems, ultimately constructing a hierarchical network topology.

[0022] Therefore, this application proposes a building security monitoring system, including a camera module, a wireless transmission module, and a power supply module. The camera module has multiple network cameras, one installed on each floor. The wireless transmission module has multiple wireless gateways, one installed on each floor, with upper-floor wireless gateways cascaded to lower-floor gateways. A router is located on the roof, connecting to the uppermost wireless gateway and the monitoring center. The power supply module has multiple energy storage battery modules, one installed on each floor, connected to the corresponding floor's network camera and wireless gateway.

[0023] Among these, network cameras can refer to monitoring devices that support wireless communication, such as IP cameras using H.265 encoding, which collect floor image data and transmit it wirelessly. Wireless gateways can refer to communication nodes with signal relay functions, such as dual-band routers supporting Mesh networking. Dual-band routers include both 5GHz and 2.4GHz bands and can use products with built-in high-gain antennas that support IEEE 802.11ac (WiFi 5 standard) or newer wireless standards to improve data transmission rates and stability. They support building multi-hop transmission links through hierarchical connections, reducing the number of times a single transmission needs to penetrate obstacles. Energy storage battery modules can refer to modular power supply devices, such as portable power supply boxes with built-in lithium batteries, which provide independent power support for each floor's equipment through localized deployment, avoiding the need for cross-floor power supply lines.

[0024] Specifically, network cameras are independently installed at the back stairwells of each floor, covering the monitored area of ​​that floor. Wireless gateways form a chain connection between adjacent floors; for example, the top-floor gateway forwards data to the next-floor gateway. The rooftop router has a built-in SIM card used for internet access, obtaining traffic from the carrier's network and converting it into Wi-Fi signals for device use. The router provides Wi-Fi network signals to the top-floor gateway, enabling video data from wireless gateways on each floor to be transmitted to the cloud server. This architecture allows the signal to penetrate only a single floor slab; for example, the attenuation of 5GHz band signals when penetrating concrete slabs can be controlled within a reasonable range. The energy storage battery module connects to the device via a pluggable interface, such as a DC 5.5 interface for power supply, automatically switching to battery power mode when external power is interrupted.

[0025] Compared to existing technologies, traditional solutions rely on a single wireless router to cover multiple floors, resulting in a sharp drop in signal strength as the signal needs to penetrate multiple floors. This solution, however, relays data layer by layer through hierarchical transmission. For example, each gateway only needs to cover the adjacent floors above and below, keeping the communication distance within ten meters. Traditional centralized power supply requires laying cables along stairwells; this solution uses distributed energy storage batteries, such as a 314Ah lithium battery pack per floor. In low-power mode, this can support continuous operation for approximately 50-70 days. For instance, network cameras typically have infrared or white light night vision lights; when these lights are continuously on, they can provide power for about 50 days, and when they are continuously off, they can provide power for about 70 days.

[0026] Through the above technical solution, this application achieves a cabling-free deployment of a monitoring system for the rear stairwell area of ​​old buildings. The wireless signal remains stable through short-range, multi-hop transmission; for example, in a six-story building, the transmission path is divided into five single-layer penetrations, resulting in a signal strength improvement of approximately 20dB compared to a solution that directly penetrates five floors. The localized power supply system eliminates the need for power line modifications; single-layer equipment failures do not affect the overall system operation; maintenance only requires replacing the energy storage battery module on the corresponding floor.

[0027] like Figure 1 As shown, the router on the top floor of the building is a 5G router. The 5G router mainly provides external network access. By inserting a 4G / 5G SIM card, users can access the external network. The wireless gateways on each floor are connected to the 5G router to facilitate receiving WIFI signals. The monitoring center includes an NVR (Network Video Recorder). Figure 1The demonstration shows two connection methods. One network connection involves the 10th-floor wireless gateway wirelessly connecting to the router, then to the 8th-floor wireless gateway, then to the 6th-floor wireless gateway, then to the 4th-floor wireless gateway, and finally to the 2nd-floor wireless gateway, forming a tiered connection with intervals. The other wireless network connection involves the 9th-floor wireless gateway wirelessly connecting to the router, then to the 7th-floor wireless gateway, then to the 5th-floor wireless gateway, then to the 3rd-floor wireless gateway, and finally to the 1st-floor wireless gateway, also forming a tiered connection with intervals. This achieves tiered network connectivity across all floors. Data can be uploaded to the cloud platform server (Smart Cloud Platform) and the NVR (Network Video Recorder) using the router's Wi-Fi network.

[0028] This application further proposes installing wireless signal repeaters on each floor, which are used to amplify and forward wireless signals.

[0029] A wireless signal repeater is an electronic device with signal gain and data packet reconstruction functions. Specifically, it can be implemented using an embedded device with a built-in power amplifier and protocol conversion module. The power amplifier enhances the signal strength to overcome energy loss caused by physical obstacles, and the protocol conversion module decodes and re-encodes the data packets to achieve signal regeneration and transmission. The amplification function refers to linearly enhancing the amplitude of the received signal through radio frequency gain technology, which can be achieved using a low-noise amplifier in conjunction with a bandpass filter. This function can compensate for signal attenuation caused by walls. The forwarding function refers to retransmitting the demodulated data packets after link-layer reconstruction. This can be implemented using a time-division duplex-based relay protocol, which can avoid phase distortion and inter-symbol interference caused when the signal penetrates multiple obstacles.

[0030] Specifically, wireless signal repeaters are deployed at specific locations on each floor. After receiving the transmitted signal from the upper-level wireless gateway, they first amplify the signal strength to a preset threshold using a power amplifier, for example, by employing a 20dB gain RF front-end module. Then, they perform cyclic redundancy check (CRC) and error correction coding on the data packets. The reconstructed signal is then transmitted to the next floor's cascaded devices via a directional antenna, forming a segmented transmission link. This hierarchical processing mechanism allows each floor to independently regenerate the signal, eliminating signal blind spots caused by staircase structures in the vertical space, while also avoiding the cumulative attenuation effect caused by multi-floor penetration.

[0031] Compared to existing technologies, traditional solutions typically only place a single repeater node at the top or bottom of the building, failing to compensate for independent wall obstructions on each floor. This solution, however, utilizes distributed repeater deployment to implement point-to-point compensation at each signal attenuation source, such as directional signal enhancement at concrete load-bearing walls at stairwell corners on each floor. This hierarchical approach, compared to single-node repeaters, shortens the signal transmission path to the straight-line distance between adjacent floors, effectively reducing the impact of multipath effects.

[0032] Through the above technical solution, this application can ensure the complete transmission of surveillance video data in the enclosed environment of the rear staircase, and the video stream latency can be controlled within the 500 millisecond threshold required for security monitoring. The layered deployment of repeaters ensures that the wireless signal reception strength on each floor remains at least -70dBm, meeting the channel quality requirements for H.265 encoded video transmission. This solution is particularly suitable for vertical stairwell environments with metal fire doors and concrete partitions, eliminating data packet loss caused by cross-floor communication.

[0033] This application further proposes that each floor corridor is equipped with a wireless spectrum analyzer, the wireless gateway is a dual-band gateway, and the wireless gateway is communicatively connected to the wireless spectrum analyzer.

[0034] Among them, a wireless spectrum analyzer refers to a monitoring device capable of detecting wireless channel quality and identifying interference sources in real time. Specifically, it can be implemented using a hardware module with a built-in frequency sweep receiver and digital signal processing unit. This device acquires electromagnetic interference distribution data of the current environment through spectrum scanning. A dual-band gateway refers to a wireless access device that supports communication in both 2.4GHz and 5GHz frequency bands. Specifically, it can be implemented using an embedded system integrating dual radio frequency chips, which has the function of switching transmission channels between the two frequency bands.

[0035] Specifically, the wireless spectrum analyzer continuously collects data on channel occupancy, noise levels, and multipath interference intensity of wireless signals within the building, and sends the analysis results to the dual-band gateway. Based on the received spectrum data, the dual-band gateway automatically switches to a less congested, idle frequency band to establish a transmission link when it detects signal attenuation or co-channel interference in the currently used frequency band. For example, when the bit error rate increases in the 2.4GHz band due to wall reflections, the gateway can switch the video stream to the 5GHz band for transmission, utilizing its strong anti-interference capabilities to maintain communication stability. This process creates a closed-loop feedback mechanism between the spectrum analyzer and the gateway, allowing frequency band switching decisions to be dynamically optimized based on real-time environmental data.

[0036] Compared to existing technologies, traditional solutions typically employ single-band gateways and lack environmental awareness, making them susceptible to signal attenuation limitations in areas with dense obstacles due to fixed frequency bands. This solution, through the collaborative operation of a spectrum analyzer and a dual-band gateway, can proactively avoid multipath interference frequency bands caused by building structures, while utilizing dual-band resources to compensate for signal attenuation, thereby constructing an adaptive wireless transmission link in enclosed environments.

[0037] Through the above technical solution, this application effectively reduces the degradation of wireless signal quality caused by wall obstruction and electromagnetic interference in enclosed areas such as back staircases, enabling the monitoring video data to maintain complete and low-latency transmission even in complex building structures, and solving the problem of unstable transmission caused by fixed channels in the prior art.

[0038] This application further proposes that the power module also includes a power controller, which has a built-in power monitoring unit and a power supply regulation unit.

[0039] The power controller is a control device that coordinates the power supply behavior of the energy storage battery module. It can be implemented using an embedded microprocessor, receiving and processing data from the power monitoring unit and sending control commands to the power supply regulation unit to maintain the stability of the device's power supply. The power monitoring unit is a functional module that monitors the remaining power of the energy storage battery module in real time. It can be implemented using a current integrator circuit or a coulomb counter chip, calculating the remaining capacity by monitoring the battery's charging and discharging current, providing a data basis for dynamic adjustment. The power supply regulation unit is a functional module that adjusts the power supply strategy according to the power status. It can be implemented using a multi-power switching circuit combined with a voltage regulation circuit, used to reduce device power consumption under low power conditions or stabilize output during voltage fluctuations.

[0040] Specifically, the power monitoring unit periodically collects real-time voltage and current parameters of the energy storage battery module and calculates the remaining power using a preset algorithm. When the power level is detected to be below a threshold, the power supply regulation unit automatically triggers a power reduction mode, such as reducing the transmission frequency of the wireless gateway or disabling unnecessary functions of the camera. When abnormal voltage fluctuations are detected, the power supply regulation unit activates the voltage stabilization circuit, smoothing the output voltage using pulse width modulation technology. The power controller integrates the data and actions of these two types of units to form a closed-loop control system, thereby prioritizing the continuous operation of critical equipment under limited power conditions.

[0041] Furthermore, the power monitoring module uses a high-precision ADC to collect battery voltage and current data in real time, and simultaneously obtains load information from the camera and wireless gateway through multiple data acquisition channels. The network camera has a built-in image processing chip that uses computer vision algorithms to analyze the video stream, statistically analyze moving object parameters through target detection, and quantify the frequency of image changes by combining inter-frame difference algorithms. At the same time, internal sensors monitor the load of hardware such as CPU and GPU in real time and upload data via SPI and I2C protocols. The wireless gateway has a traffic monitoring module and a channel scanning module. The traffic monitoring module packages and transmits data traffic on a second-level cycle, while the channel scanning module provides real-time feedback on channel occupancy. The multi-dimensional data together form the basis for load assessment.

[0042] The power switching circuit refers to the circuit structure used to change the power output of the battery. The pulse width modulation (PWM) circuit is a circuit module that controls the output voltage by adjusting the pulse width; specifically, it can be implemented using a feedback regulation system based on a PWM controller, dynamically adjusting the output duty cycle according to the real-time power consumption of the load. The power supply regulation circuit is a circuit used to eliminate voltage fluctuations and maintain a stable output voltage; specifically, it can be implemented using a linear regulator or a switching regulator in conjunction with a filter capacitor, performing high-frequency noise filtering and dynamic compensation on the input voltage.

[0043] Specifically, the power switching circuit uses a MOSFET switching array, which controls the gate voltage or trigger signal to disconnect high-power lines and turn on low-power circuits in energy-saving mode, and reverses the operation in high-load mode; the pulse width modulation (PWM) circuit dynamically adjusts the pulse duty cycle according to the command to precisely regulate the battery output power; the power supply voltage regulation circuit ensures stable output voltage in each mode by adjusting the feedback resistor network of the switching regulator.

[0044] This application further proposes that the energy storage battery module can be detachably installed in the floor.

[0045] Detachable installation refers to a physical connection between the energy storage battery module and the floor mounting carrier that can be separated. This can be achieved using a sliding rail plug-in structure, a snap-locking mechanism, or a bolt quick-release assembly, allowing the battery module to switch between a fixed and detachable state. The energy storage battery module is an independent power supply unit formed by integrating multiple battery cells. This can be achieved using a standardized enclosure structure with connectors on the surface that match the floor mounting carrier.

[0046] Specifically, the energy storage battery modules are embedded into mounting slots in floor walls or equipment cabinets via pre-set sliding rails or snap-fit ​​mechanisms. When maintenance or replacement is needed, the module can be pulled out along the sliding rail by unlocking the fixing device. Maintenance requires no drilling or cutting into the wall; simply releasing the mechanical lock separates the battery module from the mounting carrier. In renovations of older buildings, this installation method avoids trenching and wiring operations in the existing building structure, while standardized connectors allow for quick disconnection and reconnection of power lines. When a battery module on a single floor fails, the corresponding module can be directly replaced without interrupting the power supply to other floors.

[0047] Furthermore, the energy storage battery can be selected to have a hot-swappable interface.

[0048] This application further proposes a technical solution for setting an NFC chip in an energy storage battery module.

[0049] The NFC chip refers to an integrated circuit based on near-field communication technology. Specifically, it can be implemented using a radio frequency identification (RFID) chip conforming to the ISO / IEC 14443 standard. This chip is encapsulated on the surface or inside the casing of the energy storage battery module. The battery identification and information exchange function refers to the data exchange between the device and the battery via wireless communication. Specifically, it can use the NDEF data format to standardize the storage of the battery serial number and production date, and perform bidirectional data transmission through an NFC reader / writer.

[0050] Specifically, when maintenance personnel approach the energy storage battery module with a mobile terminal equipped with NFC reading capability, the NFC chip automatically activates and transmits pre-stored identification data. This data includes the battery's unique code, rated capacity, battery life, number of charge cycles, charge / discharge history, production information, etc., allowing maintenance personnel to verify the battery's identity without disassembling the equipment. During maintenance, the power controller's microcontroller writes dynamic parameters such as the battery's current cycle count and remaining capacity into the NFC chip, forming a traceable maintenance record. When replacing a battery, the NFC chip of the newly installed battery is automatically compared with the system's preset parameters. If a mismatch in voltage specifications or capacity parameters is detected, an alarm is triggered to prevent incorrect installation.

[0051] Compared to existing technologies, traditional battery management often relies on barcode labels or manual recording, which suffers from issues such as easily worn labels and difficulties in updating data. This solution, however, utilizes near-field communication (NFC) technology to achieve digital management of battery information, eliminating the risk of information loss due to easily detached physical labels, avoiding data errors that may occur during manual recording, and supporting real-time updates and remote retrieval of dynamic data.

[0052] Through the above technical solution, this application achieves contactless acquisition of battery maintenance information, reduces the operational risks associated with equipment disassembly, and improves the accuracy of battery status data collection. By storing full lifecycle battery data in the chip, maintenance personnel can quickly assess battery health, optimize replacement and maintenance plans, and effectively avoid system power supply anomalies caused by improper battery information management.

[0053] This application further proposes adding an overheat protection circuit within the power module. The overheat protection circuit is connected to the energy storage battery module and includes a temperature sensor, a control chip, and a cut-off switch.

[0054] The temperature sensor is a component used to collect real-time temperature data of the energy storage battery module. It can be implemented using a thermistor or a digital temperature sensor, and is used to continuously monitor the battery's operating temperature. The control chip is a logic unit used to process temperature data and generate control signals. It can be implemented using a microcontroller or a dedicated integrated circuit, and is used to determine whether the temperature exceeds a safe threshold. The disconnect switch is a physical device used to perform circuit switching operations. It can be implemented using a relay or a solid-state switch, and is used to disconnect the energy storage battery module from the load under abnormal temperatures.

[0055] Specifically, temperature sensors are placed at key locations on the surface or inside the energy storage battery module to continuously collect temperature data and transmit it to the control chip. The control chip analyzes the received data in real time, and when it detects that the temperature exceeds a preset safety threshold, it immediately sends a trigger signal to the cut-off switch. Upon receiving the signal, the cut-off switch disconnects the circuit connection between the energy storage battery module and downstream devices mechanically or electronically, blocking power transmission. This process is completed before thermal runaway occurs, avoiding the risk of battery damage or fire due to sustained high temperatures.

[0056] This application further proposes an energy storage battery module comprising a main battery and a secondary battery.

[0057] The main battery, typically a lithium-ion battery, provides power to the network cameras and wireless gateways on the corresponding floor under normal operating conditions. The secondary battery, acting as a backup power source, can be a battery with the same or different chemical system as the main battery and takes over power supply when the main battery is low on charge or malfunctions. The physical separation of the main and secondary batteries reduces the risk of overheating of the entire battery pack through independent installation.

[0058] Specifically, the main battery continuously supplies power to the device during normal system operation. When the power monitoring unit detects that the main battery's power level is below a set threshold or an anomaly occurs, it switches the power supply to the auxiliary battery via a switching control circuit. The auxiliary battery immediately begins supplying power after the switch, ensuring uninterrupted operation of the security monitoring system. The main and auxiliary batteries are connected to the power controller via independent circuits, and the microcontroller implements charging and discharging status monitoring and switching logic control. This architecture avoids the problem of system paralysis caused by sudden failures when powered by a single battery, as is common in traditional systems.

[0059] This application further proposes that the main battery and the auxiliary battery are respectively connected to a switching control circuit, and the power monitoring unit is equipped with a microcontroller, with the switching control circuit connected to the microcontroller.

[0060] The main battery is an energy storage unit that provides basic power to the network camera and wireless gateway. It can be implemented using a lithium-ion battery pack and is used to maintain power supply under normal operating conditions. The secondary battery is a backup energy storage unit located in parallel with the main battery. It can be implemented using a battery pack of the same specifications as the main battery and is used to take over power supply when the main battery's power is insufficient. The switching control circuit is an electronic circuit that controls the switching of the power supply path between the main and secondary batteries. It can be implemented using a combination of relays and transistors and is used to quickly switch the power path under the command of a microcontroller. The microcontroller is a computing control chip with an embedded power monitoring unit. It can be implemented using a low-power ARM architecture processor and is used to collect real-time power data from the main and secondary batteries and generate switching commands.

[0061] Specifically, when the remaining power of the main battery falls below a preset threshold, the microcontroller cuts off the power supply to the main battery via a switching control circuit, while simultaneously activating the power supply to the secondary battery. The switching control circuit physically isolates the main and secondary batteries, preventing reverse current flow or short circuits during the switching process. The microcontroller executes the switching operation with a millisecond-level response time, ensuring continuous operation of the network camera and wireless gateway during power switching.

[0062] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
