In public places such as rail transit systems, hospitals, schools, office buildings, and government service halls, clear and unified time displays are an essential foundation for standardizing work processes, enhancing service quality, and facilitating public travel. Beijing Zhongxinchuang Technology Co., Ltd. is based on With more than 20 years of expertise in time‑synchronization technology, we offer a comprehensive lineup of digital sub‑clocks—ranging from digital to analog and countdown models—featuring diverse display modes, precise time synchronization, and easy installation and deployment. These solutions meet the time‑display and time‑synchronization needs of various public venues, providing reliable time references for both the public and staff.

The core strengths of the Zhongxin Chuang Digital Sub‑Clock series lie in its seamless synchronization with time servers and its diverse product configurations. All digital sub‑clocks support… The NTP/PTP network time synchronization protocol enables the acquisition of standard time signals from a time server over LANs and WANs, achieving unified time across all subordinate clocks on the network. Time deviations are kept within the millisecond range, ensuring that subordinate clocks at different locations display perfectly synchronized times. Each subordinate clock is equipped with a high‑precision clock chip; in the event of a network outage, it can maintain time accuracy using its internal clock, and upon network recovery, it automatically synchronizes with the standard time, thereby guaranteeing continuous timekeeping.

In terms of product form, the Zhongxin Chuang Digital Sub‑Clock series covers three major categories, meeting the needs of various application scenarios. The digital sub‑clock features high brightness… LED display modules deliver crisp, eye‑catching characters with a long viewing distance, supporting multiple color options—including red, green, and blue—so they can be flexibly configured to suit ambient lighting conditions and aesthetic preferences. Display formats include hour‑only, hour‑minute, hour‑minute‑second, hour‑minute‑second plus year/month/day/weekday, and hour‑minute‑second plus year/month/day/weekday plus temperature and humidity, among others. Users can remotely configure the display content via software, eliminating the need for on‑site adjustments. The circular analog‑digital sub‑clock employs a silent stepper motor for smooth, noiseless operation, while its dial design aligns with traditional visual conventions. Available in various sizes (8 inches, 12 inches, 16 inches, etc.), it is ideal for installation in office buildings, hotels, government service halls, and other settings where environmental aesthetics are paramount. The countdown‑type digital sub‑clock allows users to customize the countdown duration and start method, set target times, and choose countdown units (days/hours/minutes/seconds), with optional audio‑visual alerts. It is well suited for scenarios requiring precise timing, such as school exams, train departures at stations, or event venues. In terms of hardware quality and installation, the Zhongxin Chuang digital sub‑clock series has been comprehensively optimized. The display modules feature high‑quality LED beads that provide uniform brightness, long service life, low power consumption, and energy efficiency, while also incorporating anti‑glare treatment to prevent reflections from bright light sources that could interfere with readability. The housings are crafted from premium ABS engineering plastic or aluminum alloy, offering excellent dust‑proof, moisture‑resistant, and aging‑resistant performance to meet the demands of prolonged indoor use; select models even support IP54 protection, making them suitable for semi‑outdoor applications. Installation options include wall‑mount, pendant, and flush‑mount configurations, with dedicated mounting brackets and fasteners provided to ensure a straightforward, flexible setup tailored to site‑specific conditions.

In terms of power supply, the digital sub‑clock series supports Two power‑supply options are available—PoE and 220V AC—catering to the wiring needs of diverse environments. PoE delivers both power and data over a single Ethernet cable, eliminating the need for separate power cabling, which significantly streamlines installation and reduces construction costs, making it particularly well suited for settings such as train stations, hospitals, and office buildings where wiring is complex or re‑wiring is impractical. By contrast, 220V AC power is ideal for new‑build projects or locations with dedicated power outlets, offering stable and reliable power delivery.

The Zhongxin Chuang digital sub‑clock series has been widely deployed in various public venues, yielding a wealth of industry‑specific application cases. In the rail transit sector, multiple lines—including the Hangzhou Metro and the Beijing Metro—have adopted Zhongxin Chuang’s digital sub‑clocks, installing them on station platforms, in concourses, at customer service centers, and other locations to provide passengers with clear time references while synchronizing with train dispatching systems to ensure operational efficiency. In the healthcare field, medical institutions such as Beijing’s Zhongguancun Hospital and Shanghai’s First People’s Hospital Bengbu Branch have chosen digital sub‑clocks that display temperature and humidity, placing them in wards, operating rooms, nurse stations, and other areas to establish a unified time standard for clinical operations and to monitor environmental conditions in real time, thereby supporting effective facility management. In education, universities like Tsinghua University and Peking University, along with primary and secondary schools nationwide, have implemented hybrid solutions combining countdown timers with standard digital sub‑clocks: the countdown clocks are used for exam timing, while the conventional units are installed in classrooms, office buildings, libraries, and other spaces to help regulate teaching schedules. In the commercial and government sectors, numerous municipal service centers and large-scale shopping complexes have selected digital sub‑clocks that integrate analog hands with digital displays, balancing aesthetics and functionality to enhance the overall image of these service environments. In addition, the digital sub‑clock series seamlessly integrates with the Zhongxin Chuang intelligent network‑wide time‑synchronization monitoring software. Through the platform, operations and maintenance personnel can remotely monitor the operating status and time‑synchronization performance of all sub‑clocks, and perform remote on/off control, display‑mode adjustments, brightness settings, and other functions. The system also supports configuring alarm notifications for abnormal conditions such as offline sub‑clocks or time deviations exceeding set thresholds, significantly reducing O&M management costs.
