Intelligent management program for hospital security personnel patrol

I. Background of the project

As a densely populated place with valuable equipment and extremely high security requirements, hospitals have a crucial role to play in day-to-day security work. Traditional security inspection relies on manual records, easy to miss, wrong inspection, and can not be real-time monitoring, security risks are difficult to detect in a timely manner. In order to improve the security level of hospitals, the introduction of intelligent inspection management program is imminent.

III. System architecture

• Sensory Layer: Dual Frequency Activator::
  • Dual-frequency activators are deployed at 10-15 meter intervals in various key areas of the hospital, such as ward areas, emergency rooms, pharmacies, equipment rooms, parking lot entrances and exits. The activators are battery-powered, with low power consumption, strong signal, waterproof and dustproof, and can be installed magnetically or wall-mounted, with a signal coverage radius of 2-10 meters, accurately marking inspection points.
• Sensing layer: network base stations::
  • Network base stations are installed within 50-100 meters of each area of the hospital for receiving tag signals in the area.
• Sensing Layer: Intelligent Terminal::
  • Equipped with customized tags for the security guards, using the tag type ZigBee dual-frequency location tags will start to work when they encounter an activator nearby, sending their own ID and the activator ID to the network reading base station, which reports the data to the management platform through the hospital's existing network (Ethernet or 4G/5G). Security personnel use cell phone APP to communicate with the management platform in real time through 4G/5G network.
• transport layer::
  • Utilizing the existing 4G/5G network of the hospital, it guarantees stable and high-speed transmission of data between the smartphone APP and the management platform to ensure timely delivery of location information, event reporting and other data.
• application layer (computing)::
  • Build an intelligent inspection management platform based on cloud servers, with modules for user management, task management, real-time monitoring, event processing, data analysis and so on. Managers can log in to the platform via PC and mobile webpage to conveniently operate various functions.
