Client: Hunan Women and Children’s Hospital, China
Industry: Healthcare / Tertiary Grade-A (Class IIIA) Specialty Hospital
Solution Provided: BeiDou + GPS Master Clock System, NTP Network Time Servers, Surgical Timing Displays, Wireless Corridor Clocks
Hunan Women and Children’s Hospital is a modern Class IIIA medical institution built to meet international JCI standards, featuring 150,000m² of medical facilities and 350 open beds. As a leading provincial medical center responsible for maternal and pediatric healthcare, emergency rescue, research, and teaching, the hospital’s intelligent management systems rely heavily on accurate and unified time.
However, before the upgrade, several timing issues caused operational risk:
Clock deviations of up to 5 minutes between departments
Surgical room timers not synchronized with the HIS medical system
Inconsistent timestamps in LIS / PACS / EMR records
Risk of documentation mismatch and medical procedure disputes
These conditions created workflow inefficiencies, scheduling confusion, and potential compliance issues.
In 2024, the hospital partnered with SHUTAI (a brand of Changsha Tianqiong Electronic Technology Co., Ltd.) to deploy a full smart timing system based on BeiDou + GPS dual-mode satellite signals.
| System Component | Function |
|---|---|
| BeiDou + GPS Master Clock | Provides 50ns precision satellite reference time |
| NTP Network Time Server | Synchronizes HIS, LIS, PACS, EMR & medical devices |
| Surgical Countdown / Anesthesia Clocks | Forward & reverse timing for procedures |
| Corridor & Waiting Area LED Clocks | High-visibility dual-sided digital displays |
| Nurse Station Calendar Clocks | Time + Date + Weekday medical record validation |
| LoRa Wireless Communication | 1,000m coverage, no wiring required |
Dual-Mode Time Source: BeiDou + GPS with automatic signal switching for 90% improved anti-interference performance.
High Precision:
Master clock accuracy: 50ns
Sub-clock deviation: ≤10ms across the hospital
Wireless Expansion: LoRa network (398–525MHz) reduces construction cost by 30%.
Smart Monitoring: Real-time fault detection, automatic alarm push, remote diagnostics & updates.
| Outcome | Improvement |
|---|---|
| Surgical Workflow Accuracy | +60% efficiency in OR time handover |
| Medical Record Accuracy | EMR timestamp consistency 100% matched |
| Patient Experience | Waiting area satisfaction improved to 98% |
| Operations & Management | Hospital-wide coordination +45% |
| Long-term Maintenance Cost | Annual savings of approx. 40% |
“The SHUTAI time system eliminated our internal ‘time islands’. Every clock—from OR to laboratory to the registration hall—now runs in perfect synchronization. It significantly improved safety, efficiency, and patient trust.”
