Rail Transit
Satellite timing is easily obstructed by tunnels, terrain and other environmental interference. The compatibility of multiple devices and multiple protocols is complex, and network delay jitter affects synchronization accuracy.
Business Pain Points
Satellite timing is easily obstructed by tunnels, terrain and other environmental interference.
The compatibility of multiple devices and multiple protocols is complex, and network delay jitter affects synchronization accuracy.
At the same time, there is a lack of effective monitoring and redundant design, making it difficult to meet the high-precision, high-reliability and consistency requirements of time synchronization in scenarios such as vehicle-road collaboration, signal control, and toll billing.
SaiSi Advantages
Applications in rail transit, airports, transportation hubs, smart cities, and connected vehicles
The clock system is a crucial component of rail transit systems. Its primary function is to provide unified standard time information to control center dispatchers, station attendants, staff from various departments, and passengers. It also provides unified time signals for subway communication systems and other systems (such as signaling, AFC, ISCS, and ACS). The clock system plays a crucial role in ensuring accurate subway operation timing and improving operational service quality.
