Building Tower Clock Tower Bell First, Yantai Qiming Clock Product Introduction 1. Walking time: microcomputer control, fully automatic operation. The mother and child clock system adopts closed-loop control to keep the mother and child clocks running synchronously, and the monthly error is not greater than ±1 second. 2. Lighting: There are two types of lighting methods. One is the use of LED light-emitting diodes, which have a long service life, and the lighting life is more than 100,000 hours. The color is red, yellow and green to choose from, and the effect is soft and beautiful; the second is the use of the clock face as a whole for internal lighting. Two modes of lighting time can be adjusted arbitrarily, and the opening and closing time are automatically controlled. 3. Timekeeping: Using the method of music first and then scoring, the timing content can be customized according to user requirements, and the opening and closing times are automatically controlled. The timing power is 200 watts, which can be increased or decreased. It is also possible to add a music library to the top of the time reporting function through the computer center, so that any music and advertisement in any language can be reported at any time. 4. GPS satellite calibration time: The microcomputer center and the satellite signal receiving device are connected to compare and proofread the separated standard time and the mother clock time to ensure that the operation of the tower clock is synchronized with the standard time, so that there is no accumulation error. 5. Automatic tracking function: After a power outage, the mother clock automatically remembers within 6 months. After an incoming call, the sub-clock can automatically track to the standard time without special adjustment. The power protection system can also be added according to user requirements to ensure that the system does not stop power outages. 6. Fault self-diagnosis function: When a part of the system fails, the tower clock controller automatically diagnoses the fault and transmits the fault phenomenon information to the control center. The control center immediately displays the fault part and indicates how to eliminate the fault. 7. Microcomputer monitoring: Using the Pentium processor and the monitoring software and hardware equipment developed by our company itself, it can adjust and monitor the walking, lighting, timing and other functions of various tower clocks. ① Monitor and control the operation of the mother and child clocks. ② Modify and set the timing track ③ Process the signal sent by the sub-clock system in real time, and control the lighting and timing of the sub-clock in real time. ④ Display the mother clock time and adjust the mother clock time synchronously. ⑤ View or reset the lighting zone. ⑥ Display help information for computer operation at any time. 8. Synchronization function of each face clock: When a face clock is out of sync with another face clock, the control system automatically detects and automatically adjusts it to synchronization.
