What are the components of a hospital clock system?

Feb. 05, 2026

The concept of time is fundamental to life, particularly within hospital systems where time is critically valuable. Every system and module requires clock synchronization, which is referred to as the hospital clock system. To ensure time synchronization across all departments and hospital systems, thereby minimizing issues and accidents caused by time discrepancies and providing better service guarantees, the hospital clock system serves as an optimal solution to this challenge.

What are the components of a hospital clock system? Is its setup cumbersome and complex?

This is a common concern for hospital administrators. Simply put, a clock system typically consists of a time server, satellite receiving antenna (commonly referred to as a "mushroom head"), multiplexer, and various clocks or display clocks, along with components such as feeder cables, network cables, switches, and so on.

The time server is the cornerstone of the hospital's time synchronization system. Without it, all other components become secondary. This device, commonly known as an NTP (Network Time Protocol) clock, transmits time signals to subordinate clocks and sub-clocks.

The steps for synchronizing the hospital clock are as follows:

1. The satellite receiving antenna captures GNSS time signals and transmits this data to the time server. Note that the satellite's placement must meet specific criteria: it should be installed on a rooftop with unobstructed surroundings, ensuring clear visibility of the sky and no dead zones to prevent signal instability.

2. The time server transmits its generated time signals to subordinate clocks, sub-clocks, or time-keeping terminals via algorithmic functions. These devices are commonly referred to as subordinate clocks or sub-clocks. A critical consideration is that each sub-clock or time-keeping terminal must have its own independent IP address to prevent IP conflicts among devices within the local network, which could disrupt clock synchronization.

3. Regarding the connection of clocks, sub-clocks, and time synchronization devices, the primary consideration is the total number. Depending on the hospital's scale, these devices must be networked to the time server (master clock) via a switch, typically using network cables. For large-scale hospitals, multiple time servers may be required.

Synchronization parameters for hospital clock systems: Currently, most hospitals use millisecond-level time synchronization, typically implemented through NTP network clock devices, resulting in millisecond-level accuracy. However, certain hospital equipment and systems may require higher-precision clock synchronization, necessitating the use of PTP time servers.
