The building tower clock is the pulse signal output by the main clock, which is driven by the movement drive unit to drive the stepping motor and the movement to drive the pointer to achieve the purpose of timing. At the same time, the microcomputer automatically tracks, detects, proofreads and adjusts the tower clock to ensure that the tower clock is always synchronized with the main clock. The system is controlled and managed by a closed-loop microcomputer. No matter how long the power failure is, after the power failure is restored, the auxiliary clock will automatically correct the time to the current time without manual adjustment.
The night lighting is automatically turned on, which is very convenient for operation and maintenance, and realizes unattended management. The system has strong anti-interference ability, fault self-diagnosis function and lightning protection function. The master clock in the control system determines the time accuracy of the tower clock. The tower clock has been calibrated with imported instruments before leaving the factory, and the accuracy is within 0.1 seconds (there is no GPS satellite time calibration system under normal ambient temperature). In addition, the system has the characteristics of high control integration, small footprint, power saving, strong stability, and low heat generation (which can greatly improve the service life of electronic components). The building tower clock can not only display the time like everyone else, but also play the role of lighting. The following editor will introduce to you its luminous form.
1. The clock dial is translucent luminous-the entire clock dial is bright. The clock dial usually uses a milky white light-transmitting PC board, and a fluorescent lamp is used behind the clock dial to direct light.
2, pointer scale luminous-pointer scale is made into a light box structure. LED light sources are usually used internally. When the dial diameter is less than 2 meters, it is recommended that customers use the dial translucent luminous; when the dial diameter is greater than 2.5 meters, it is recommended to use the pointer scale luminous. It can be flexibly controlled between 2 meters and 2.5 meters.
3. Spotlight lighting: illuminate the entire panel by lighting around the building's tower clock.
