5. The device meets industrial-grade hardware standards for wide temperature ranges, ensuring reliable year-round continuous operation in factory data centers. 7×24 Hours of continuous operation.

VI. Solution

In conjunction with the multi‑workshop, cross‑regional industrial network architecture of the Sichuan Lutianhua Energy and Chemical Plant, Beijing Zhongxin Chuang provides… DNTS-9 Tier-1 Network Time Synchronization Overall Solution:

1. Time‑source architecture: Deploy dual BeiDou receiving antennas with zone‑specific installation; the device features a built-in dual‑satellite receiver, supports customizable prioritization of BeiDou signals, and provides mutual redundancy among multiple satellite systems, ensuring stable timing signals even in complex outdoor environments.

2. Continuous timekeeping assurance: With an optional domestically produced rubidium atomic clock module, the system can maintain high‑precision timekeeping even when satellite signals are completely lost, ensuring an uninterrupted time reference for the production control system.

3. Network Layered Synchronization: DNTS-9 As the primary standard time source for the plant, it is connected to the core switch and provides downstream connectivity to the secondary switches in each workshop. DCS Provided by the control cabinet, security server, and energy metering terminal. NTP Standard time‑synchronization signal; the network port provides physical isolation between the production network and the office network.

4. Security and Operations Management: Built-in device access blacklists and whitelists, login logs, and operation audit features, along with配套 DNTS Manager Management software that enables centralized monitoring, remote configuration, fault alerts, and historical synchronization log storage for multiple clock servers.

5. Industrial environment adaptation: The entire system meets - 10℃~+55℃ Data center wide-temperature operating standards, supporting dual-redundant power supplies, with a mean time between failures of up to 90000 Hours, tailored to the year-round, continuous production environment of the chemical industry.

VII. Implementation Outcomes

1. The plant’s industrial control, security, energy metering, and office information systems all maintain time synchronization within milliseconds, effectively resolving the issues of inconsistent log timestamps across systems and the difficulty of tracing the root causes of production failures.

2. Dual antennas + A dual-receiver redundant architecture significantly reduces the risk of timing interruptions caused by site obstructions and electromagnetic interference, ensuring stable, uninterrupted timing services throughout the year.

3. The domestically developed hardware architecture aligns with the enterprise’s indigenous innovation (XinChuang) transformation plan and complies with information security management standards for the energy and chemical industries.

4. A centralized operations and maintenance management platform reduces the cost of equipment inspections across multiple workshops on the plant floor, and automatically pushes alerts for anomaly‑related faults, significantly improving O&M response efficiency.

5. Following its deployment, the system successfully passed the enterprise’s internal audit for production safety compliance, meeting the required time‑based benchmarks for chemical‑process data traceability and post‑incident analysis.
