The building clock can be randomly combined by music, language and dot three ways, and the system is composed of a controller and an external driver and additional equipment. The controller is composed of dual CPU system design. The controller can run by itself or manually. The controller remembers the clock parameters after power failure, and automatically tracks the needle to the current Beijing time after power on. The controller can work normally and reliably regardless of whether the GPS can receive the satellite signal system. Under normal circumstances, the controller can deal with the error problem of the clock module for a long time by itself, and will automatically correct and time Beijing Standard time after a certain period of operation. The two-needle movement can complete high-speed needle pursuit in about 45 minutes.
Manual setup operation can handle complex unexpected situations and bring the clock system into normal working state as soon as possible. The front panel of the controller is composed of LCD screen buttons and indicators. The front panel is the interface for man-machine communication. The back of the case is equipped with a terminal connecting the device. See the controller front panel graphics: Operation process: First install the minute hand and hour hand overlap at 12 o 'clock position; After the controller is connected with the driver and auxiliary equipment as required, it can be checked and automatically entered the waiting state.
The needle moving system of the electromechanical tower clock is mechanical, and the control system is in the form of sub-clock. The tower clock is a sub-clock, which receives the electrical pulse signal regularly issued by the high-precision mother clock, and indicates the time through the stepper motor driven by the needle mechanism, and runs synchronously with the mother clock. The chimes or music that strikes the hour are produced by tape recording or program control. The mechanical tower clock uses the weight as the power source, and indicates the time by driving the needle mechanism through the mechanical transmission, and tells the time by beating the specially cast "clock".
