- Overview of Beidou timing device
- Independently designed and developed by Jinan Weishang Electronics Co., Ltd.
- A series of network synchronization clocks
are specially used
- High-quality product for protocol synchronization of server and workstation clocks across the entire network. In today's rapidly developing Internet era, the reading and storage of network data files, online settlement and payment systems, e-commerce systems, online
- systems, storage and maintenance of databases and many essential network applications Neither can do without a high-precision synchronized clock.
- The product is mainly used to receive
- Beidou satellite signals and process them to generate time synchronization signals in various formats (serial port, pulse,
-code,
-,
-). It has
-pulse level test port and internal timing function. If there is an error in the
- signal, the external
- signal can be automatically used to obtain the time reference signal, so that the time reference signals can be used as backup for each other. The switching time is less than
- seconds. During the switching, the main clock output Time synchronization signals are error-free. If neither information is correct, the device outputs a time signal via the internal clock.
- Scope of application
- Suitable for all industries that require precise synchronization with standard satellite time, such as:
- Transportation sector: railways, airports, air traffic control.
- Network system: network accounting, network management, distributed file processing, e-commerce, email, system security, public time resources.
- Integrated systems for communications, electric power, national defense, finance, and taxation.
-Public service facilities: hospitals, TV stations, schools, public security, etc.
