The network electronic clock system is a clock system using NTP network protocol to schedule time. NTP network protocol can synchronize computer time and other network devices. The network electronic clock system is the satellite signal received by the NTP network time server as the time reference and transmitted to the sub clock or other network equipment by network signal. The network electronic clock system uses the satellite time signal to provide accurate timing, and ensures the equipment time synchronization and time service accuracy in the LAN.

With the continuous progress of science and technology, the performance and accuracy of timing equipment are also improving. The clock equipment which is widely used is a clock device that can receive satellite signals. For example, the network electronic clock system takes satellite signal as the time benchmark. The network electronic clock system is accurate and convenient to use, and saves a lot of manpower and material costs. It meets the needs of many places for time service equipment. Xi'an synchronous Electronic Technology Co., Ltd. is a professional manufacturer of time-frequency equipment. The company has more than 10 years experience in R & D and production of time-frequency equipment. Its product performance is stable and reliable. The company's products include time server, time calibrator, timing equipment, IRIG-B code product, cPCIe time card, pulse distributor, high stability crystal oscillator, rubidium atomic frequency standard (GPS/ Beidou). Tame, multi-channel time interval tester, phase meter, time tester, PTP precision clock, sub clock and so on, and this product has been applied in many places and industries.

Xi'an synchronous Electronic Technology Co., Ltd. is invited to provide a set of network electronic clock system for the Shanxi energy revolution vanguard exhibition hall. The network electronic clock system takes the satellite time signal as the time source and provides time to display the clock equipment and other network terminal devices in the library, so that the time of all clock equipment and network terminal equipment in the exhibition hall synchronize with the time of the network electronic clock system, and ensures the clock equipment, monitoring system, computer, access control system, auxiliary lighting and emergency broadcasting system in the exhibition hall. The time of one key alarm system, timing equipment and multimedia equipment is accurate, avoiding a series of problems caused by time errors and time synchronization in exhibition hall.

The Shanxi energy revolution vanguard exhibition hall, the network electronic clock system scheme is as follows:

Master clock: SYN2136 Beidou NTP network time server

Satellite antenna: SYN108 GPS Beidou dual-mode timing antenna

NTP interface box: SYN4505A clock synchronization system

422 interface box: SYN4505 standard synchronous clock

Single sided pointer clock: SYN6132 pointer clock

Time unified monitoring system V1.0

After receiving the GPS Beidou satellite signal, the master clock is transmitted to the 422 interface box, and the 422 interface box is transmitted to the computer and other terminal devices. The mother clock receives the GPS Beidou satellite signal and then passes it to the NTP interface box. The NTP interface box is transmitted to the sub clock and other terminal devices through the network switch. When the child clock is connected with the switch through the network cable, it needs to carry out the timing in the sub clock management software, and specifies the IP of the master clock to synchronize.
