The clock system is divided into indoor and outdoor parts. The indoor master clock mechanism system is divided into three sub-chassis: main control chassis, power supply box, and expansion chassis. The outdoor part is the sub-clock part, which can be divided into the movement pointer, scale, lighting system and time signal speaker.
Principle introduction
The master clock has its own clock circuit to generate a second signal with an accuracy of 2 seconds/month. At the same time, the CPU continuously receives the time signal from the GPS signal, and corrects its own time signal to ensure the accuracy of its time signal. The master clock continuously sends the time signal to the slave clock, and the slave clock is driven by the driving signal when the time is accumulated for 15 seconds.
