Ningbo Municipal Hospital of T. C. M receives over 3,000 patients daily, placing extremely high demands on its ward call system.
Hospital Demands
l 24/7 uninterrupted operation: The ICU and emergency ward call systems must be absolutely reliable.
l High-density access requirements: A single-floor ward must support 200+ call terminals simultaneously.
l Millisecond-level response requirements: The latency from a patient's call to the nurse's station must be less than 1 second.
l Complex electromagnetic environment: Dense medical equipment necessitates a network with superior anti-interference capabilities.
Solution
Utilizing an industrial PoE switch architecture to achieve a "zero-perception upgrade" of the security system for the medical facility.
10G Access
10G core Layer 3 managed industrial PoE switch forms the digital foundation for the ward call system:
l Operates from -40℃ to 75℃, IP40 protection rating.
l Dual redundant power supply supports power outage protection, ensuring the system never goes offline.
l 48*1000M PoE ports and 4*1/10G optical ports, with a single port power of up to 30W. IEEE 802.3af/at standard automatically identifies powered devices, ensuring a safe power supply.
Network Architecture
l MSTP multi-instance protection (<50ms switching): Achieves dual redundancy at the device and link levels.
l Intelligent power management: PoE ports support priority settings, ensuring priority power supply to critical ward call terminals.
l ERPS ring network technology (<20ms): Automatically restores communication within 20 milliseconds in the event of a link failure.
Intelligent cloud control management
ONV-NMS management platform and mobile APP dual-terminal implementation: Unified network management software platform, enabling visualized management of the status of all network devices.
l Mobile: Real-time push notifications of device alarms, zero-latency triggering of maintenance responses
l Platform: Visualized management of the entire network device topology, automatic diagnosis of anomalies and alarms
Key Value
l Fault warning and location: Automatic detection of device anomalies, precise location of fault points.
l Real-time PoE power supply status monitoring: Voltage, current, and power consumption of each port are clearly displayed.
l Remote maintenance and configuration: Supports multiple management methods such as Web and CLI, reducing on-site maintenance.
Solution Highlights
l The equipment lifecycle is extended by 2 times; industrial-grade design ensures zero-failure operation for 5 years.
l System maintenance costs are reduced by 60%, and remote management reduces on-site maintenance work by 80%.
l Call response speed increased by 3 times, and patient waiting time reduced from an average of 2.3 minutes to 45 seconds.
l Nurse work efficiency increased by 40%, and zero-latency data transmission allows nurses to respond to patient needs faster.
