1、 Network time synchronization display system ( Master clock system ):
adopt NTP Time calibrator ( Master clock ) Automatically receive GPS Satellite or China's Beidou satellite signal , After being processed by the main board of satellite time service signal , Then the standard time signal is synchronized with network time NTP/SNTP At the same time sent to more than one standard time display screen that can receive the signal ( Secondary clock ) Or computer network system , Thus, the network and each location with the slave clock can display the Beijing time which is consistent with the satellite time signal .

2、 The system adopts network time synchronization technology :
Network time synchronization technology is based on NTP/SNTP Standard low power network time protocol , The technology under this agreement is a long distance 、 Low power LAN communication technology . In the master clock ( Time calibrator ) When the system transmits synchronous signals , There are many sub clocks in the area ( Monitor ) Receive the signal synchronously , Communication and processing through network , Make each slave clock display exactly the same time , Fundamentally solved the office building each time is not synchronized the present situation .

3、 Network time synchronization display system :
Standard time synchronous display sub master clock system consists of satellite signal receiving module 、CPU Single chip processor 、NTP Network processing module 、 And the standard time display module consists of four parts ( Here's the picture ).

4、 Historical reform of the system
Standard time synchronous display slave and master clock system is mainly used in the production of unified requirements for standard time 、 Dispatch unit , Such as : School 、 The hospital 、 radio 、 Power plant 、 subway station 、 Airports and high-end business and office buildings . Its appearance , Will set off a lot of enterprises and institutions and government agencies keen attention , At the same time, Beidou satellite has been widely used in China . This technology combines network time protocol digital clock technology with satellite time service technology , It breaks the tedious twisted pair wiring work of traditional analog serial bus slave clock and the confusion of inaccurate time delay , It also broke the market position that has dominated for more than ten years , It will be the innovation and reform of the new generation digital network master clock system .

The system is not only convenient for enterprises and institutions to accurately time , It can greatly improve their work efficiency , The improvement of efficiency means the improvement of social public service , And enterprises and institutions have a strong focus on time , It's their sense of service and efficiency . At the same time, it has industry-leading environmental performance , Leading the trend of urban green office . With the accelerating pace of modern life , The popularity of networking , The demand for time accuracy is also increasing , Especially the current subway and railway stations 、 The hospital 、 School 、 The government authority 、 Enterprises and institutions just meet their needs , Solve real problems for them .
