NTP network time server is a time server that uses NTP network time protocol to schedule time. NTP network time protocol is a protocol used to synchronize computers. It can provide high-precision time information for timing. The NTP network time server takes the satellite signal as the time benchmark and outputs the signal through the network, serial port and second pulse.

Under the rapid development of information technology and network technology, various industries are also moving forward and developing. The timing and types of time service for time service equipment in various industries are constantly changing, and the accuracy, stability, portability and anti-interference of the timing equipment are increasingly demanding. The NTP network time server is based on the GPS Beidou satellite positioning signal as the time base, and the NTP network time server is simple to operate, convenient to use and accurate in timing. Industry needs. The time server can provide unified standard Beijing time information for some schools, hospitals, power plants and research institutes, and ensure the equipment time in LAN is uniform and accurate.

NTP network time server mainly uses NTP network to provide time service, and it is more powerful than the earlier SNTP network protocol. The NTP network time server can provide many kinds of time service devices. As long as it can accept network signals, it can give time, and its timing accuracy is in millisecond level, which can be expanded to Gigabit output. The time server has firewall, hardware and software watchdog, supervisor. Control time error, Web management, software monitoring and management. The management software of the product can monitor the working state of the time server. Batch software can synchronize the batch client time to the time server, provide time interval and time error settings for time service software, and can also add more IP addresses. The alarm can choose satellite failure, time synchronization and power supply, and can also increase the function of SNMP network management and heartbeat detection function. For redundant backup.

The time server and the network sub clock are used together, so that the accurate time can be displayed better. The SYN2104 NTP network time server receives the GPS timing antenna to receive the satellite signal, and outputs the NTP network, serial port, second pulse and other time information after the internal conversion of the time server. Then the NTP network clock server transfers the standard time signal to SYN6132 through the switch. Pointer clock, SYN6109 NTP network clock, computer, industrial computer, monitoring equipment, and so on, and enable the time synchronization between devices. The time server has a high precision timekeeping module, which can provide precise time when power failure or no satellite signal is available.
