Description

Full-automatic calendar mechanism

Affiliated technical field

The utility model relates to the calendar mechanism in timing field.

Background technology

In the timing field various calendar manifestation modes are arranged, the digital demonstration arranged, pointer indication, rotating disk demonstration etc.Existing pointer or rotating disk calendar mechanism and clock train link mechanically, and from " day " to " moon " in the calendar be not simple system, often very important person's wage adjustment is whole at the end of month to cause calendar mechanism, very difficult realization is automatically changed and is gone through.

Summary of the invention

The utility model adopts the pointer showing calendar, and having overcome existing pointer calendar mechanism needs the artificial inconvenience of adjusting, and has realized automatically changing going through.

The technical scheme that its technical matters that solves the utility model adopts is: calendar mechanism and clock train are not to link mechanically, but relatively independent mechanism, by programmable logic device control drag source, drive the calendar mechanism train again, drive the pointer indication date at last.If the drag source enough little stepper motor that is step angle can directly drive the pointer indication date by motor shaft.Step angle described here is enough for a short time to be meant: the numerical value that step angle multiply by the showing calendar of wanting is not more than 360 degree angles.For example: indicate " day ", if the step angle of stepper motor be not more than 11.6 the degree be step angle enough little (because: 11.6 multiply by 31 equals 359.6 the degree angles).Owing to use programming device, thereby be easy to realize automatically changing going through.Can adopt a plurality of separate trains to drag by separately drag source respectively for going through, and control can be realized by 1 programmable logic device more.

If want automatically operate as normal of calendar mechanism, calendar mechanism also must possess two conditions: 1. calendar, time and actual calendar, the time synchronized of controlling the programmable logic device of calendar mechanism operation.2. the date of calendar mechanism indication is synchronous with the actual date.

Satisfy above-mentioned the 1st condition, could guarantee that calendar mechanism changed and goes through in the correct time (0 front and back), can know that just of that month fate is several, can go through in correct changing at the end of month.

Satisfy above-mentioned the 2nd condition, could guarantee the date of the pointer indicating correct of calendar mechanism.

If calendar mechanism and clock are made same product, calendar mechanism can use same programmable logic device with clock, or the programmable logic device of calendar mechanism uses the temporal information of clock.Thereby as long as moment and standard time basic synchronization of clock just can realize satisfied the 1st condition.

If calendar mechanism and clock are not same products, can in product, increase the time system of a band calendar, using programming device is to realize easily, what this time system can be by button adjustment realization and current time is synchronous.

Especially for easier realization of calendar mechanism and the basic synchronization of standard time that can pass through communication mode (wireless or wired) time of reception calendar information.

Can realize the 2nd condition by artificial adjustment mode.If in the train of calendar mechanism, add position transducer then can realize that the date and the actual date of calendar mechanism indication are synchronous automatically by programmable logic device.

In the accompanying drawing 2: 1. programmable logic device, 2. drag source, 3. calendar indicator, 4. calendar-disc.

Embodiment

Accompanying drawing 3 is an example of the present utility model, 3 cover trains are arranged in the calendar mechanism, the afterbody of one of them train is output as axle, the afterbody of two other train is output as tubulose, axle second of similar to Clock and Watch in time is in charge of, 3 trains respectively by 3 stepper motors (2) as drag source, and stepper motor (2) by microcontroller (1) (or being called single-chip microcomputer or MCU) as programmable logic device control, therefore be easy to realize automatically changing going through.Thereby the date and the actual date that position transducer (6) can be housed in the train can realize the calendar mechanism indication are synchronous automatically.

Existing watch and clock movement generally mostly is 1 cover train, but two covers relatively independent trains is also arranged, and is commonly referred to as 2 pin transfer movements; 3 overlap the 3 pin transfer movements that are called of relatively independent train.So-called transfer, i.e. Hour Minute Second pin isolated operation separately, and unlike 1 cover train gear core, be subjected to the restriction of intrinsic ratio of gear between each pin.

The international market is early existing produces in enormous quantities, and the radio wave clock movement of the independent train of two covers that producing in enormous quantities has also appearred at present in home market, the advantage of the lower cost of utilizing existing radio wave clock movement making calendar mechanism can make full use of the production in enormous quantities of existing clock movement and forming is produced calendar mechanism of the present utility model.

The second hand indication week that can utilize second wheel to be, and utilize the minute hand of timesharing train to indicate day, the hour hands indication moon.

Because second hand moved for 60 steps weekly, be used for indication during the moon, carrying out 12 five equilibriums with 60 is easily, promptly changes 5 steps of 1 operation of moon second of time motor.

Although week is 7 systems but because the resolution of second hand is enough high, and also be to realize easily by microprocessor controls.For example available 9 steps, 8 steps, 9 steps, 8 steps, 9 steps, 8 steps, 9 steps are as 1 circulation (totally 60 steps).Can certainly all change Zhou Li with 8 steps or step number still less, corresponding week disk needn't form the ring of sealing.And just in time can utilize this collar extension blank space (among Fig. 5 (7)) to place trade mark or factory's name etc.

The minute hand majority of radio wave clock movement is 1 step of 10 seconds or 15 seconds operation, is 240 steps or 360 steps so minute hand moves 1 week (360 degree), is used to indicate day can indicate the method in week to handle with reference to second hand equally.Therefore utilize the radio wave clock movement of existing 2 pin transfers can produce moon diurnal 3 easily and go through mechanism.

Because of the system number in week is little, thereby the space of display disc is bigger, can be divided into two lattice the every day in week and be respectively applied for expression morning and afternoon (Fig. 4).This calendar mechanism is particularly useful for the needs indication special occasions of morning and afternoon, as World clock, and underground fortification, submarine etc.

Calendar mechanism of the present utility model not only can automatically change and go through, and owing to most temporal organizations do not move, thereby power consumption is extremely low, can use solar powered when being used for the open air.

Because the complicacy of calendar system will really realize automatically changing going through, using microcontroller (MCU) to control as above-mentioned programmable logic device is best at present selection.

Because the radio wave clock movement can receive electric wave signal (long wave time signal), and position transducer is housed in the movement, thereby as long as by changing the program of microcontroller, can be satisfied fully: 1. calendar, time and actual calendar, the time synchronized of controlling the programmable logic device of calendar mechanism operation.2. the date of calendar mechanism indication is synchronous with the actual date.Thereby can be transformed into the electric wave calendar mechanism to the radio wave clock movement.

Change wired or other forms of wireless data communications interface into as original radiowave interface, this movement can be transformed into the secondary clock movement in the princip al and subordinate clock system of wire communication the radio wave clock movement.Equally, change the wherein program of microcontroller, can satisfy calendar, time and actual calendar, the time synchronized of the programmable logic device of 1. control calendar mechanism operations equally.The date of calendar mechanism indication synchronous with the actual date, thereby can use it for showing calendar in the princip al and subordinate clock system.
