Synchronous clock device
(Timing device, Beidou synchronous clock products, network time correction) Introduction:
The clock produced by Jinan Weishang Electronics Co., Ltd. is based on the global positioning system Technical standard time display and sending device. It is the global satellite navigation system of the United States. It consists of satellites operating in space and ground control stations. At any place on the earth's surface and at any time, the satellite signal receiver can receive a sufficient number of satellite signals, and the receiver can accurately calculate The current spatial position and time are located, and the time accuracy can reach nanosecond level.
This equipment is specially designed and manufactured for the power system's time synchronization requirements for various equipment such as monitoring, control, protection and fault recording. The design complies with the "Technical Specifications for Time Synchronization System of East China Power Grid" and is especially suitable for timing services. It is used in occasions where the reliability of synchronization system is very high. The product uses a receiver with two parallel receiving channels and a 3-meter active antenna. After searching and locking satellites, the receiver can calculate and give accurate time information, including pulse air contact time synchronization signals, R/, R3 serial time synchronization signals, level and modulated B code time synchronization signals, etc. Multi-channel timing signals. The product also has a network time server module based on the /protocol, which can be applied to the system time adjustment of the Ethernet (local area network) network of the power measurement and control system.
The device adopts an inch/standard chassis and has a modular structure design. It is equipped with a variety of functional modules for flexible combination and easy expansion.
