Abstract
Description
Technical Field
[0001] This invention belongs to the field of monitoring technology, and in particular relates to an intelligent monitoring device based on a PON passive optical network. Background Technology
[0002] In current elderly care and community security scenarios, while traditional monitoring equipment can record basic images, it cannot identify and proactively warn of emergencies such as falls by the elderly or accidental falls by children. For example, when an elderly person living alone slips and falls at home or a child falls suddenly in a community playground, the existing monitoring system can only mechanically store the images, requiring continuous manual monitoring of the screen to detect the danger. There is often a delay of several minutes or even longer between the occurrence of the event and human detection. This "post-event review" mode cannot provide effective warnings within the golden rescue time, which greatly increases the risk of secondary injuries such as fractures and concussions caused by falls.
[0003] With the aging population and the increase in dual-income families, the market demand for monitoring equipment has upgraded from "being able to see" to "being able to understand and respond quickly," requiring the system to have automatic alarm push capabilities. However, existing products are unable to meet the rigid requirements of "zero-delay monitoring" in elderly care institutions and "no blind spots in safety coverage" in communities, forcing users to configure additional devices such as fall alarm wristbands and emergency buttons, which not only increases the cost of use but also leads to low management efficiency due to the fragmentation of multiple systems. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing monitoring systems in elderly care and community security, which can only provide monitoring but cannot provide immediate warnings or tracking of falls or other security issues for the elderly or children, thus failing to meet the current market demand for monitoring equipment. Therefore, this invention proposes an intelligent monitoring device based on a PON (Passive Optical Network).
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent monitoring device based on a PON passive optical network, comprising:
[0006] The monitoring equipment has a bracket at the bottom, which is connected to a mounting plate. The mounting plate is connected to a base. The monitoring equipment adopts a decoupled hardware architecture and supports posture recognition, human activity monitoring and environmental anomaly detection.
[0007] The solar panel is connected to the base. The monitoring equipment is equipped with a warning device. Both the warning device and the monitoring equipment are equipped with a battery, which is connected to the solar panel.
[0008] Furthermore, the monitoring equipment is equipped with a connecting shell at the bottom, with a bracket connected to both sides of the connecting shell, and anti-vibration pads are provided between the mounting plate and the base.
[0009] Furthermore, the aforementioned decoupled hardware architecture includes:
[0010] Perception module: Unifies the data format of multiple types of sensors through hardware abstraction layer, supports posture recognition, human activity monitoring and environmental anomaly detection, and collects real-time data in scenarios such as elderly / child falls and theft.
[0011] Computing module: Provides tiered computing power options, dynamically loads AI models, and enables localized real-time processing of functions such as fall recognition and theft detection;
[0012] Communication module: integrates PON optical interface and wireless backup link, supports dynamic wavelength allocation and star-chain topology reconstruction, and ensures the reliability of abnormal event warning information transmission.
[0013] Furthermore, the aforementioned star-chain topology dynamically adjusts the optical splitter connections by integrating a software-defined networking (SDN) controller in the optical line terminal (OLT). When the backbone fiber fails, the optical network unit (ONU) forms a subnet through a wireless mesh or backup fiber link to maintain local monitoring functions and ensure that warning information for elderly / child falls or thefts is not interrupted.
[0014] Furthermore, the aforementioned computing module adopts an edge-cloud collaborative AI architecture;
[0015] Edge: Deploy lightweight chips in the ONU, run posture recognition models and behavior analysis models, and trigger real-time alerts for elderly falls or theft incidents;
[0016] Cloud-based: Connects to the cloud platform via OLT, runs complex correlation analysis models, and uses federated learning to optimize the global model to achieve cross-camera tracking of stolen people's trajectories;
[0017] Collaborative mechanism: Feature vectors or early warning signals are uploaded at the edge, and spatiotemporal correlation analysis is performed in the cloud to generate intervention instructions.
[0018] Furthermore, the aforementioned decoupled hardware architecture also includes a dynamic resource blockchain scheduling system, which achieves resource optimization through the following steps:
[0019] (a) Each ONU acts as a blockchain node and publishes information on bandwidth, computing power, and storage requirements;
[0020] (b) The smart contract prioritizes fall warnings over regular monitoring based on event priority; it dynamically matches resources to ensure that the delay in handling emergency events is ≤50ms.
[0021] Furthermore, the various types of sensors supported by the aforementioned sensing module include:
[0022] Visible light camera: used for posture recognition and detecting falls;
[0023] Infrared thermal imager: Nighttime human activity monitoring to help assess the elderly's condition;
[0024] Millimeter-wave radar: Non-contact vital sign monitoring, providing early warning of abnormal conditions in the elderly;
[0025] Environmental sensors: temperature and humidity detection, gas concentration detection, and associated risk analysis.
[0026] This invention provides an intelligent monitoring device based on a PON (Passive Optical Network). Through multimodal sensing and edge-cloud collaboration, this device achieves a leap from passive monitoring to proactive early warning: In elderly care scenarios, the non-contact monitoring of millimeter-wave radar and infrared thermal imager avoids the burden of wearable devices for the elderly. Combined with posture recognition from a visible light camera, it can trigger an alert within 50ms after an elderly person falls and push it to family members or medical terminals, significantly reducing the risk of secondary injury. In community security scenarios, the linkage between environmental sensors and behavioral analysis models can detect fire hazards and theft in real time, while a blockchain scheduling system prioritizes urgent needs. Emergency resources ensure that warning information is restored and transmitted within 10 seconds, improving emergency response efficiency. The decoupled architecture and solar power supply design reduce deployment costs and improve environmental adaptability, while vibration damping pads and stable supports ensure the accuracy of sensor data. Ultimately, this forms a full-process intelligent security system covering "monitoring-analysis-early warning-linkage," meeting the urgent needs of aging societies and smart communities for high-reliability, low-latency monitoring, and improving the management efficiency of elderly care communities and security. In addition, solar panels are placed on top of the monitoring equipment, along with vibration damping pads, to protect the monitoring equipment from rain and vibration, extending its service life.
[0027] Therefore, this embodiment has the following advantages compared to the prior art:
[0028] A smart monitoring device based on PON (Passive Optical Network) solves the problem that existing monitoring systems in elderly care and community security can only play a monitoring role, but cannot provide immediate warnings and tracking of falls or other security issues for the elderly or children, thus failing to meet the current market demand for monitoring equipment.

[0040] Please see Figure 1-2 This invention provides a technical solution: an intelligent monitoring device based on a PON passive optical network, comprising:
[0041] The monitoring device 1 has a bracket 2 at its bottom, which is connected to a mounting plate 3. The mounting plate 3 is connected to a base 4.

[0044] Specifically, see Figure 1-2 The decoupled hardware architecture includes:

When the backbone fiber fails, the optical network unit (ONU) forms a subnet through a wireless mesh or backup fiber link to maintain local monitoring functions and ensure that warning information for elderly / child falls or thefts is not interrupted.

[0058] Collaborative Mechanism: Feature vectors or early warning signals are uploaded from the edge device, and spatiotemporal correlation analysis is performed in the cloud to generate intervention commands. By combining timestamps and geographic location information, intervention commands are generated, such as locking access control systems or notifying family members, achieving full automation from detection to response.
