1. Principles of Building Tower Clocks
Tower clocks are divided into two categories from the outside: indoor and outdoor. The indoor one has a master clock control system.The outdoor part is the slave clock, which can be divided into the movement, clock hands, scale, lighting system and hourly time signal speaker.The outdoor clock controller itself has a clock circuit to form a data signal with an accuracy of 2 seconds/month. At the same time, the CPU continuously receives the time data signals from GPS and Beidou signal machines, and corrects the individual time data signals to fully ensure the accuracy of the time signals. The master clock continuously sends the time data signals to the slave clock, outputs the drive data signal to drive the motor to work, and completes the travel time. The slave clock returns its state to the master clock and accepts the supervision of the master clock. At the same time, the travel time of the slave clock is also supervised by the feedback switch, fully ensuring that the entire slave clock constitutes a closed-loop system. The master clock and the slave clock form a large closed-loop system. Therefore, the authenticity and effectiveness of the entire building clock system are ensured.
2. The value of school rooftop clocks
As a special environment for educating people, schools have completely different time concepts. Students are the future of the country, and they should cultivate the habit of being punctual and cherishing time from an early age. In the planning and design of contemporary schools, large clocks are often considered.
This kind of large clock is what we professionally call a "tower clock". It is large in size and difficult to assemble. It is usually installed on the top of a bell tower or tower. However, because it can quickly and easily remind people of the time, and its design is unique, it has become an indispensable beautiful landscape in the building.
The school assembled tower clock can not only set the hourly time interval and hourly time content according to needs, but also set the night light effect, which is convenient for seeing the time. Because it tracks GPS satellite time and adjusts the time by itself, it keeps accurate time. Many stations, schools, and communities have such outdoor clocks.
