A small, independently operable time server based on the NTP/SNTP protocol can obtain standard clock signal information from GPS satellites and transmit this information over the network.
The network time server is a high-tech product for the computer and control device in the automation system. The network time server acquires the standard time signal from the GPS satellite and transmits the information to the automation system through various interface types. Equipment that requires time information (computers, protection devices, fault recorders, event sequence recording devices, safety automation devices, telecontrol RTUs) can achieve time synchronization of the entire system.
The network time server is manufactured using SMT surface mount technology. The large-scale integrated circuit design is controlled by a high-speed chip. It has high precision, good stability, strong functions, no accumulated errors, and is not limited by the environmental conditions such as regional climate and high cost performance. Features such as simple operation, fully automatic intelligent operation, free operation and maintenance, unattended and widely used in electric power, finance, communications, transportation, radio and television, petrochemical, metallurgy, national defense, education, IT, public service facilities and other fields.
Network Time Protocol Introduction
The NTP (Network Time Protocol) was proposed by Professor David L. Mills of Delaware University in 1985. In addition to estimating the round-trip delay of packets on the network, it can also independently estimate the computer clock deviation, which can be realized on the network. High-precision computer calibration is a communication protocol designed to enable different machines to maintain the same time on the Internet. A time server is a type of server that utilizes NTP, which allows machines in the network to maintain time synchronization. In most places, NTP can provide 1-50ms reliable synchronous time source and network working path.
A detailed description of Network Time Protocol (NTP) is in RFC-1305 [Mills 1992]. RFC-1305 gives a clear explanation of the NTP protocol automata in terms of events, status, transition functions, and behavior. It uses appropriate algorithms to enhance the accuracy of the clock, and relieves multiple errors due to the synchronization source, achieving time service with accuracy lower than milliseconds to meet the needs of path measurement in the current Internet.
NTP is a complex synchronous time protocol that spans a wide area network or a local area network. It typically yields millisecond accuracy. RFC 2030 [Mills 1996] describes the Simple Network Time Protocol (SNTP), which is intended for hosts that do not require full NTP for complexity. It is a subset of NTP. Usually allow several hosts on the LAN to synchronize clocks with other NTP hosts over the Internet, and then provide time synchronization services to other clients on the LAN
