Regional clock movement and control design method

Abstract

The invention discloses a regional clock movement and a control design method, and belongs to the technical field of time instruments. The regional clock movement comprises movement clamping plates, a stepping motor, a clock pointer assembly and a gear reducing transmission mechanism, and is characterized in that: the regional clock movement comprises a synchronous reducer motor; a gear at the output end of the synchronous reducer motor is directly meshed with a secondwheel which is fixedly arranged on a secondwheel shaft; and the secondwheel is provided with a hole and a photoelectric switch is arranged at two ends of the hole. The control design method comprises setting and control of power supply of the clock movement, time base, hour hand and minute hand driving, second hand driving, and alarm information feedback items. Compared with the prior art, the clock movement and the control design method have the prominent substantive characteristics and obvious progress that: the second hand continuously moves, and the clock is ensured to work for 3 hours to wait for connecting a main power supply after the 220V main power supply is cut off; when the clock movement is not powered by the main power supply, the hour hand and the minute hand automatically return to twelve clock, so passengers notice alarm information that the clock is failed and cannot delay the travel; and the like.

Description

A kind of regional clock movement and control design method technical field The invention relates to the technical field of timing instruments, in particular to a regional clock movement suitable for regional installation, remote control and automatic calibration and a control design method. Background technique With the rapid development of urban construction, especially the continuous completion of new modern transportation hubs such as stations, ports, airports, and subways, the analog clock not only provides decorative embellishments for public places, but more importantly, it Provide time display and time telling services to mobile people, and constantly remind people to cherish time and work hard to speed up their pace and race against time. The main technology as an analog clock is the design of the clock movement, especially the intelligent regional clock movement suitable for networking, unified calibration and remote control. The announcement number of the China...

Problems solved by technology

As the terminal sub-clock movement of the intelligent regional clock, this clock movement has played a positive role in advancing the analog clock to the regional clock, but there are also obvious technical defects. The disc causes the photoelectric detection disc to be repeatedly set on the sub-wheel shaft and the sub-wheel piece, which not only increases the carrying load of the sub-wheel shaft but also wastes materials and increases costs; the second is that there is no second hand transmission device, and the existing second hand transmission publicly used at home and abroad is The second wheel shaft is meshed with the stepping motor through a two-stage gear reduction transmission mechanism. Not only is the reduction transmission mechanism complicated, but also the driving of the stepping motor drives the second hand to run with jumping needles, and its visual effect is not good; the third is the existing use area The clocks are directly powered by 220V main power supply. Once the main power supply is disconnected, the terminal clocks will all stop, which is especially easy to cause an illusion to passengers and cause delays in time; Issues urgently needed to be solved by technicians in the technical field
