With the rapid development of information technology and network technology, all the universities and hospitals in China are in strict accordance with the regulations of the relevant departments of the state, and have configured the network electronic clock display system, providing unified standard Beijing time information for schools. The accuracy of GPS network electronic clock time hung in corridor hall, classroom and consulting room is of great significance.

The network electronic clock display system is usually composed of a clock NTP network time server and a digital clock. The mother clock receives the GPS or Beidou satellite signals directly through the antenna, and then sends all the sub clocks in the LAN in real time by the core switch. The Beidou GPS satellite signal has already covered all the territory of China, and only needs mushroom head antennas in open areas such as balconies or roofs.

The network electronic digital clock has the characteristics of precise timing, convenient operation and synchronous operation. The intelligent modular design highlights the characteristics of simple operation, convenient installation, reliable operation, long service life and high cost performance. There are single and double-sided digital Zi Zhong, calendar clock, pointer clock, operation room bell and army Zi Zhong and other specifications to choose from, to meet the needs of different units and different occasions, the corresponding models are SYN6109 and SYN6132.

The network electronic clock display system, that is, the time display, is mainly installed in the hospital corridors, nursing station, toll booth, lounge, consulting room and other places. When choosing, we need to consider the following points:

A. determines the contents of the sub clock (year, month, day, hour, minute, second, week, temperature, humidity).

B. determines the size of the sub clock (the actual size is determined according to the digital tube).

C. determines the color of the digital tube (the standard is red, and the red is recommended on the visual and generous).

D. determine the single and double sides of the child clock (hospital corridor, suggest double sided, other locations depending on the situation).

In practical applications, network electronic clock has the function of relay. The master clock and the single and double-sided digital clock can be connected directly or through a switch. The NTP receiving port of the network electronic clock is connected to the NTP sending port of the parent clock by a network cable. Generally speaking, tens of units or even hundreds of sub clocks need to be given time. At this time, the network function is needed to connect the network electronic clock and the master clock to the core switch.

The appearance of the network electronic clock display system is sprayed with black matte plastic on the surface of the metal frame and inlaid with light colored plexiglass in the frame, which is beautiful and atmospheric. In use, we have configuration software, one-time batch processing will change all the sub clock IP, the superior server points to the same interface, and avoids the trouble of multiple direct connection settings.
