Building clock photoelectric tracking device, is used to track. The master clock controls the motor drive, and its role is to use the building clock for accurate timing, time calibration and time system conversion. It is composed of a master clock, gear train, worm gear, three photoelectric switches, time-minute light block, conductive slip ring, insulation sheet, AC reversible asynchronous motor, time-system switching switch, amplifier circuit, solid-state relay and various supports.
At the beginning of operation, according to the travel time, by manually pressing the button, the number of seconds of a day's error is preset, and after converting the CPU to the initial timing value, the value of TL0 is calibrated, so that the building clock has a certain accuracy at the beginning, and then the input Beijing time signal is self-calibrated once a day, so that the electronic clock composed of T0 has a high precision and has a single master clock control. The whole machine runs stably and reliably at the same time, the gear train structure is reasonable and compact, and the installation and use are convenient.
The output end of the spiral wheel shaft of the building clock is connected with the over-wheel drive, the over-wheel is connected with the over-wheel shaft, the output end of the over-wheel shaft is connected with the spur gear drive, and the spur gear is connected with the minute hand shaft; The middle of the minute hand shaft is connected with the cross-wheel drive, the cross-wheel is connected with the cross-wheel shaft, the output end of the cross-wheel shaft of the building clock is connected with the time gear drive, and the time gear is connected with the hour shaft. The building bell structure is very compact, the weight is very light, and the area is small. The building clock realized the linkage and coordinated operation
