Zhongxin Chuangwei provides a precision clock for Chongqing Welfare Lottery.

Recently, the Chongqing Welfare Lottery Center issued a request for a time server. Beijing Zhongxin Chuang Company proactively collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑9 clock device as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the Chongqing Welfare Lottery Center’s clock synchronization project.

Chongqing Municipal Society Welfare The Prize‑Winning Fundraising Committee was established in 1988 by… Chongqing Municipal People’s Government Approved for establishment, specializing in… Chongqing City of Welfare lottery Issuance management work. The Municipal Social Welfare Prize‑Draw Fundraising Committee Office (hereinafter referred to as the “Municipal Fundraising Office”) is established under it to carry out day‑to‑day operations. In 1996, with approval from the Municipal Organization and Establishment Commission, the Chongqing Municipal Welfare Lottery Issuance Center (hereinafter referred to as the “Municipal Welfare Lottery Center”) was set up; it operates as a single institution with two separate nameplates alongside the Municipal Fundraising Office. The Municipal Welfare Lottery Center is… Chongqing Municipal Civil Affairs Bureau A directly affiliated public institution.

The Chongqing Welfare Lottery Center conducted an in-depth evaluation of the DNTS‑9 clock server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the center expressed high satisfaction with both our product quality and after-sales service, leading to a successful procurement and deployment.

The DNTS-9 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an advanced, intelligent, high-precision NTP network time server. The DNTS-9 obtains standard time information from navigation and positioning satellite systems such as GPS, BeiDou, GLONASS, and Galileo, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can thereby synchronize with international standard time.

When used in conjunction with GNSS satellite receivers, priority can be configured; the system supports single‑receiver/dual‑receiver and single‑antenna/dual‑antenna configurations, with each receiver capable of operating in either standalone or combined timing modes. If both receivers and all other available time sources lose signal, the DNTS‑9 relies on its built-in temperature‑controlled crystal oscillator or rubidium atomic clock to maintain accurate timekeeping, continuously providing time services to external users.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑9 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides high‑precision standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑9 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors.

The DNTS-9 network time server is extremely easy to install and use: simply connect the satellite receiving antenna and plug the network port into a network switch, and you can achieve time synchronization across all devices on the network.
