Control design method of regional clock cassette mechanism

Abstract

The invention discloses a control design method of a regional clock cassette mechanism, which belongs to the technical field of timing instruments. The regional clock cassette mechanism comprises a cassette mechanism splint, a stepper motor, a clock hand component and a gear reducing transmission mechanism; the control design method of the regional clock cassette mechanism has the characteristicsthat: the regional clock cassette mechanism comprises a synchronous reducing motor, a gear on the output end of the synchronous reducing motor is directly meshed and connected with a second wheel which is directly arranged on a second wheel shaft, and a hole is arranged on the second wheel and a photoelectric switch is respectively arranged on both ends of the hole. The control design method comprises the steps of power supply to the clock cassette mechanism, the driving to a time base, an hour hand, a minute hand and a second hand, and the setting and the control of alarm information feedback items. Compared with the prior art, the control design method of the regional clock cassette mechanism has the significant and substantial characteristics and significant progress that: the second hand continuously works, a clock can still work for three hours after a 220V main power supply is disconnected to wait for the connection of the main power supply; but if the power from the main power supply is still not obtained, the hour hand and the minute hand are automatically reset to a 12 o'clock position, so that the alarm information that 'the clock fails to work, please pay attention and do not delay the travel time' and the like is sent to a traveler.

Description

[0001] This application is a divisional application for an invention patent filed on April 10, 2010 by the applicants: Yantai Watch Institute Co., Ltd. and Yantai Polaris High-Based Time Synchronization Technology Co., Ltd. The original application number: 201010145962.8, the name of the invention The invention is: a regional clock movement and a control design method. technical field [0002] 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 [0003] 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 co...

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
