Wuhan Mingde Biotechnology Co., Ltd. (Stock Code: 002932.SZ) was established in 2008 and is located in Wuhan Optics Valley BioCity, a national biopharmaceutical industry hub in China. The company is a national high-tech enterprise dedicated to the independent R&D, manufacturing, and commercialization of in vitro diagnostic (IVD) products, while also providing integrated medical informatics solutions and third-party clinical laboratory services.
Leveraging years of technological accumulation, Mingde Biotechnology has built a comprehensive product ecosystem supported by 10 core technology platforms, covering immunoassay, blood gas analysis, and molecular diagnostics. The company has formed a regional collaborative intelligent diagnostics solution, centered on rapid and precise diagnostic products and connected by critical care information systems, enabling full-process coverage across pre-hospital, in-hospital, and post-hospital scenarios.
Today, Mingde Biotechnology serves 7,500 medical institutions across 30 provinces, municipalities, and autonomous regions in China, and provides products, services, and technical support to over 50 countries and regions worldwide.
Under China’s Good Manufacturing Practice (GMP) regulations, every stage of pharmaceutical production—including material input, equipment operation, environmental monitoring, and batch record management—must be supported by accurate, traceable, and tamper-proof timestamps.
Any inconsistency or deviation in time records can:
Invalidate batch production records
Compromise product traceability
Introduce serious regulatory and audit risks
Prior to the project, Mingde Biotechnology relied heavily on manual inspection and calibration of system clocks, resulting in several critical issues:
Time Desynchronization
Computers, data loggers, and systems across cleanrooms, production lines, and laboratories exhibited second-level to minute-level time discrepancies.
High Labor Costs
Dedicated personnel were required to regularly calibrate hundreds of clocks, with low efficiency and high error risk.
Audit Vulnerabilities
Inconsistent timestamps are considered major non-conformities during GMP audits and directly impact certification outcomes.
To address these risks, Mingde Biotechnology decided to deploy a fully automated, high-precision time synchronization system in its core cleanroom production areas.
After rigorous technical evaluation and product comparison, Mingde Biotechnology selected Changsha Tianqiong Electronics’ Embedded PoE Satellite-Synchronized Clock as the optimal solution—fully aligned with pharmaceutical cleanroom requirements.
Each clock integrates a high-sensitivity BeiDou/GPS dual-mode satellite receiver, directly acquiring satellite signals to provide millisecond-level standard time accuracy, eliminating time drift at the source.
The PoE design enables power and data transmission over a single Ethernet cable, delivering key benefits:
Simplified cleanroom cabling
No additional power wiring or wall penetrations
Reduced contamination and safety risks
Full compliance with cleanroom principles of minimal penetrations and minimal piping
The clocks are flush-mounted with smooth, flat panels:
No hygienic dead zones
Easy to clean and disinfect
Compliant with strict cleanroom requirements for dust-free, non-accumulating surfaces
Connected via the existing factory LAN, the clocks function as NTP time servers, automatically synchronizing:
Cleanroom computers
PLC controllers
Environmental monitoring systems
Production and laboratory equipment
This approach completely replaces inefficient and error-prone manual time calibration.
Multiple embedded PoE satellite-synchronized clocks were deployed across Mingde Biotechnology’s core clean production workshops and laboratories, achieving comprehensive coverage of critical areas.
Since the system went live, Mingde Biotechnology has achieved substantial improvements:
100% GMP Compliance
Unified time across all critical equipment ensures accurate electronic timestamps, enabling smooth internal and external audits and robust product traceability.
Improved Operational Efficiency
Manual time calibration has been fully eliminated, saving significant labor costs and removing human-error risks.
Enhanced Data Reliability
MES (Manufacturing Execution System) and LIMS (Laboratory Information Management System) now operate on a unified, trusted time reference, strengthening digital factory data integrity.
Stable, Low-Maintenance Operation
PoE power supply reduces failure points. Since deployment, the system has operated 24/7 with exceptional stability and minimal maintenance.
The project manager at Mingde Biotechnology commented:
“Time management is the cornerstone of GMP compliance. Changsha Tianqiong Electronics’ embedded PoE clock solution not only resolved our long-standing time synchronization challenges with advanced technology, but its compact embedded design and PoE architecture were clearly developed with pharmaceutical cleanrooms in mind. This system is a critical component of our intelligent, compliant manufacturing strategy. Its accuracy and stability have exceeded our expectations.”
The successful implementation at Wuhan Mingde Biotechnology Co., Ltd. clearly demonstrates the critical role of precise time synchronization in modern pharmaceutical manufacturing.
With a deep understanding of regulated industrial environments and strong technical expertise in satellite time and frequency technologies, Changsha Tianqiong Electronics delivers high-precision, reliable, and fully compliant timing solutions that protect product quality and regulatory integrity.
As a professional provider in the time and frequency domain, Changsha Tianqiong Electronics Co., Ltd. continues to support hospitals, pharmaceutical enterprises, schools, government agencies, and industrial users with authoritative time and frequency standards. Shutai® synchronized clocks have become a preferred brand in China, providing trusted time services for a wide range of institutions and contributing to the high-quality development of the healthcare and life sciences industries.
