Overview
Clock is four face, high-quality PC panel,complex design galvanized steel clock minute hand, hour hand and ,skeleton behind is also made of galvanized steel tube.
Adventage
1. Master clock and master slave distributed control structure: the whole system is divided into sub clock, movement, clock, GPS antenna etc ..
2. Travel time function: automatic control and management, screen display, automatic two needle operation, master clock system exceptions closed loop control, synchronous operation remain synchronized clocks and time consistent with beijing time.
3. GPS satellite timing function: the computer center and the satellite signal receiving device is connected, will be separated from the standard time and clock time comparison, proofreading, in order to ensure the operation and standard time tower clock synchronization, travel time daily error of less than plus or minus 0.1 seconds,achieved without accumulated error.
