Intelligent Management Solution for Hospital Security Personnel Patrols

I. Project Background

Hospitals, as places with high personnel density, valuable equipment, and stringent safety requirements, rely heavily on effective daily security operations. Traditional security patrols, dependent on manual record-keeping, are prone to missed or incorrect inspections and lack real-time monitoring, making it difficult to promptly identify potential safety hazards. To enhance hospital security standards, the implementation of an intelligent patrol management solution is imperative.

III. System Architecture

• Perception Layer: Dual-frequency Activator:
  • Dual-frequency activators are deployed at intervals of 10-15 meters in key hospital areas such as wards, emergency rooms, pharmacies, equipment rooms, and parking lot entrances/exits. Battery-powered for low consumption and strong signal, they are waterproof, dustproof, and can be magnetically attached or wall-mounted. With a signal coverage radius of approximately 2-10 meters, they precisely mark patrol points.
• Perception Layer: Network Base Station:
  • Network base stations are installed within a 50-100 meter range in various hospital areas to receive tag signals from within their coverage zone.
• Perception Layer: Smart Terminal:
  • Security personnel are equipped with customized badge-style ZigBee dual-frequency positioning tags. When a tag detects a nearby activator, it activates, sending its own ID and the activator's ID to the network reader base station. The network base station then reports this data to the management platform via the hospital's existing network (Ethernet or 4G/5G). Security personnel use a mobile APP to communicate in real-time with the management platform over 4G/5G networks.
• Transmission Layer:
  • Leverages the hospital's existing 4G/5G network to ensure stable, high-speed data transmission between the smartphone APP and the management platform, guaranteeing timely delivery of location information, incident reports, and other data.
• Application Layer:
  • An intelligent patrol management platform is built on a cloud server, featuring modules for user management, task management, real-time monitoring, incident handling, and data analysis. Management personnel can log into the platform via PC or mobile web browsers for convenient operation of all functions.
