Smart Hospital Solution - Ningbo Municipal Hospital of T. C. M Ward Call System

In the wards of Ningbo Municipal Hospital of T. C. M, every press of the call button is crucial to patients' health and safety. Traditional ward call systems suffer from pain points such as insufficient stability, response delays, and complex maintenance. ONV, with its industrial-grade PoE full-scenario networking solution, built a "zero-interruption, intelligently managed" smart ward call system for the hospital.

Ningbo Municipal Hospital of T. C. M receives over 3,000 patients daily, placing extremely high demands on its ward call system.

• 24/7 uninterrupted operation: The ICU and emergency ward call systems must be absolutely reliable.
• High-density access requirements: A single-floor ward must support 200+ call terminals simultaneously.
• Millisecond-level response requirements: The latency from a patient's call to the nurse's station must be less than 1 second.
• Complex electromagnetic environment: Dense medical equipment necessitates a network with superior anti-interference capabilities.

Utilizing an industrial PoE switch architecture to achieve a "zero-perception upgrade" of the security system for the medical facility.

10G core Layer 3 managed industrial PoE switch forms the digital foundation for the ward call system:

• Operates from -40℃ to 75℃, IP40 protection rating.
• Dual redundant power supply supports power outage protection, ensuring the system never goes offline.
• 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.

• MSTP multi-instance protection (<50ms switching): Achieves dual redundancy at the device and link levels.
• Intelligent power management: PoE ports support priority settings, ensuring priority power supply to critical ward call terminals.
• ERPS ring network technology (<20ms): Automatically restores communication within 20 milliseconds in the event of a link failure.

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.

• Mobile: Real-time push notifications of device alarms, zero-latency triggering of maintenance responses
• Platform: Visualized management of the entire network device topology, automatic diagnosis of anomalies and alarms

• Fault warning and location: Automatic detection of device anomalies, precise location of fault points.
• Real-time PoE power supply status monitoring: Voltage, current, and power consumption of each port are clearly displayed.
• Remote maintenance and configuration: Supports multiple management methods such as Web and CLI, reducing on-site maintenance.

• The equipment lifecycle is extended by 2 times, industrial-grade design ensures zero-failure operation for 5 years.
• Call response speed increased by 3 times, and patient waiting time reduced from an average of 2.3 minutes to 45 seconds.
• System maintenance costs are reduced by 60%, and remote management reduces on-site maintenance work by 80%.
• Nurse work efficiency increased by 40%, and zero-latency data transmission allows nurses to respond to patient needs faster.
