The core of the domestic information technology innovation industry is to achieve independent and controllable hardware, software, and firmware. As the foundation of hardware devices, the localization rate of components directly determines the level of device autonomy and controllability. In the development of time servers, Beijing Zhongxinchuang Technology Co., Ltd. adheres to the principle of selecting domestically produced core components, opting for high-quality domestic brands across the board—from processors and memory to hard drives, power supplies, and motherboards—thus creating truly independent and controllable time synchronization equipment and providing reliable hardware support for information technology innovation projects.

• The Core Significance of Selecting Domestically Produced Components ：

1. Secure and Controllable: Mitigates the risks of technical backdoors and supply disruptions associated with foreign‑made components, ensuring the time‑synchronization security of critical infrastructure.
2. Compatible with XinChuang: Meets the procurement requirements of domestic components for XinChuang projects in Party and government agencies, state-owned enterprises, and central enterprises (domestic component ratio…). ≥90%);
3. Technological Autonomy: Promote the technological iteration of domestically produced components and enhance the domestic industrial chain’s capacity for independent R&D.
4. Cost Optimization: A stable domestic component supply chain can reduce equipment procurement and maintenance costs.

• Selection and Application of Domestically Produced Components for the China–Singapore Innovative Time Server

• Core Component Selection

1. Processor: Selected Hefei Semiconductor The 3000/5000 series and the Phytium 2000+/5000 series domestic CPUs adopt a proprietary architectural design, delivering performance that meets international mainstream standards. They support multi-core configurations and high clock frequencies, thereby satisfying the concurrent processing requirements of time servers.
2. Memory: Compatible with domestic memory modules from Changxin Storage, Hefei GigaDevice, and other manufacturers; capacity support included. 8GB–64GB; compatibility and stability have been rigorously tested to ensure long-term, fault-free operation.
3. Hard drive: We have selected domestically produced SSDs from companies such as Yangtze Memory Technologies and Yizhixin Technology ( SSD), featuring fast read/write speeds and excellent shock resistance, with a mean time between failures (MTBF) of ≥1 million hours, ensuring secure storage of system configurations and log data;
4. Motherboard: A domestically developed, in-house designed motherboard, featuring a multi-layer architecture. PCB design, compatible with domestically produced CPUs and components, supports hardware-level encryption to prevent firmware tampering.
5. Power Supply: Uses domestically produced redundant power supplies from brands such as Huawei and Huntkey, supporting a wide input voltage range ( AC 110V~240V, with over-voltage, over-current, and short-circuit protection to ensure stable power supply.
6. Time‑synchronization module: Independently developed Beidou time‑synchronization module, supporting BDS‑B1/B2/B3 multi‑frequency signal reception, fully replacing imported timing modules, with timing accuracy at the nanosecond level.

• Component Integration and Testing

1. Compatibility testing: After assembling all domestically produced components, conduct… A 1,000-hour continuous‑operation test verifies the compatibility of the CPU, memory, hard drive, and motherboard, ensuring no blue screens, system crashes, or performance degradation.
2. Environmental Adaptability Testing: In Within a temperature range of –40°C to +85°C and at 85% relative humidity, the components’ stable operational performance is tested to meet industrial‑grade environmental requirements.
3. Performance Testing: Verifying Domestic Localization Through Stress Testing The CPU’s concurrent processing capability supports over 500,000 simultaneous client requests with a latency of ≤1 ms, matching the performance level of comparable international products.
4. Security Testing: Certified by the National Information Security Evaluation Center, verifying the components’ tamper‑resistance and intrusion‑prevention capabilities to ensure the secure operation of the equipment.

• Effectiveness of Domestic Component Applications  

Case Study: A Bank’s Indigenous Innovation Transformation Project - Project requirements: The domestic content ratio of the time server must be ≥95%, it must be compatible with the Kylin operating system, and it must support time synchronization for the core trading system. - Implementation configuration: The DNTS‑9HG domestically developed time server is selected, with 100% domestic content for its core components (Hygon 5000 CPU, Changxin memory, Yangtze Memory SSD, and a self‑developed motherboard).

  Application Outcomes: 1. The equipment has passed the IT innovation adaptation certification, with a domestic content ratio that meets the project requirements, successfully replacing imported time servers.

2. Continuous operation With one year of trouble-free operation and timing accuracy consistently maintained within 0.5 μs, it ensures time synchronization for the bank’s core transaction system.
3. The domestic component supply chain is stable, reducing maintenance costs. 30%, earning high recognition from the bank.

• Industry Application Value The use of domestically produced components has enabled the Zhongxin Chuang time server to achieve from… The transition from “assembly” to “independent R&D” has truly fulfilled the core requirement of “self-reliance and controllability.” Not only does it meet the procurement standards of the information technology innovation (ITI) projects, but its stable performance and cost advantages have also enhanced the product’s market competitiveness. As domestic component technologies continue to advance, Zhongxin Chuang will keep refining its component selection process, further elevating the level of localization for time‑synchronization equipment and contributing to the development of the ITI industry.
