In recent years, yet the only professional development of NTP clock server running successfully in Qingdao city traffic command center. Welcomes the intention to inquire. High quality time server products from Jinan Wei Shang Electronics Co., an independent development and production of NTP clock server module is a based NTP / SNTP protocol. The module access to standard time information from the GPS, via NTP / SNTP protocol to synchronize all network computers, controllers and other equipment, network timing, because it has a high accuracy, unlimited transmission distance and other characteristics, is now in widely used in many industries. In today's era of rapid development of Internet, read and store network data files, online knot, payment systems, e-commerce systems, online B2B systems, preservation and maintenance of the database, and many essential Web applications are unable to leave high Accuracy of the network when the time correction module, which combines high-speed large-capacity network interfaces, and Internet-based user interface, support for multiple network protocols, to create a real time synchronization network has great significance. The product is the NTP time server in the true sense, technically leading domestic level, has reached the technical level of similar foreign products. The interface uses a network of mostly domestic manufacturers to provide SNTP protocol or port will be converted into a RJ45 interface, this approach can not guarantee the accuracy of the time, but for different operating systems need to develop the appropriate software can be achieved when the network when , so that the system of considerable limitations and inaccuracies, and can not meet the real meaning of network.
