Main functions of the CJ-3800 type tower clocknI. Timing: Microcomputer control, fully automatic triple needle operation, the second hand runs like water, bringing a dynamic feel to the overall building, the second hand has an automatic feedback function. The master-slave clock system adopts closed-loop control, timing is synchronized with Beijing time.nII. GPS satellite time correction: Connected with the control center and satellite signal receiving equipment, the separated standard time and the master clock time are compared and corrected to ensure that the operation of the tower clock is synchronized with the standard time, achieving no accumulated error.nIII. Time announcement: SVM5530 music time announcement. Announcement methods include:n① Big Ben melody plus bell sound ② Bell sound ③ Stop broadcasting. Any of the above three methods can be selected at will.nIV. Illumination: There are two types of illumination (optional): ① Illumination inside the dial face; ② All pointers and scales use LED light-emitting diodes for illumination, with a long service life, continuous uninterrupted illumination for over 100,000 hours; the illumination effect is soft and beautiful, and the illumination area can be adjusted at will.nV. Automatic tracking function: After a power outage, the master clock automatically remembers for several months, and after power is restored, the slave clock can automatically track the standard time without the need for manual adjustment. It can also be determined according to user requirements, the power outage does not stop the clock time.nSynchronization function of each slave clock: When a slave clock is out of sync with other slave clocks, the control system automatically detects and adjusts it to synchronization automatically.
