Abstract

The utility model provides an intelligent timing clock with a perpetual calendar, which is composed of a pointer type analog clock and a digital-display calendar. The utility model adopts a microcomputer-controlled digital-display circuit which drives a luminous diode LED display screen to display month calendars, day calendars and week calendars in digits automatically. The utility model has the advantages of novel and beautiful structure, adaptation to people's accustomed usage modes, capacity of indicating complete time clearly, visually and accurately and automatically adjusting leap years and big and small months. The utility model is an ideal novel timing appliance for household, offices and public places.

Description

Intelligent perpetual clock

The utility model belongs to a kind of timing tool, particularly relates to the intelligent perpetual calendar self-clocking clock that has micro computer.

The calendar timing clock is the timing tool that often uses during people live, particularly work as people and handling bill, sign the genus file, in the processes such as arrangement schedule, all need to understand correct time at that time, as month, date, the time etc. are though existing calendar timing clock has the date to show, but owing to show complicated, not directly perceived, and be difficult to direct resolution, do not meet the traditional custom use-pattern of people.In addition, also have a kind of electric turnover calendar board, can not indicate the complete times such as monthly calendar, calendar, Zhou Li visual and clearly, and need manually adjust profit year, big solar month of 30 days equal time variation, in use make mistakes easily, make troubles to the user.The utility model provides a kind of energy accurate, clear, intuitively, automatically indicates and demonstrate the intelligent perpetual calendar timing clock of complete time.

The perpetual calendar timing clock of the utility model design is an one with simulated clock and digital display date structure, is installed on the same card, and simulated clock adopts crystal clock; The display screen of digital display date by microcomputerized control shows that display screen adopts LED, shows monthly calendar, calendar, Zhou Li automatically by digital form.

With reference to the accompanying drawings the utility model is done further narration below, Fig. 1 is a schematic appearance of the present utility model; Fig. 2 is a structured flowchart of the present utility model; Fig. 3 has provided the electrical schematic diagram of this calendar timing clock; Fig. 4 has provided and has used monolithic processor controlled circuit diagram.

The utility model is by simulated clock ［ 1 ］, clock shell ［ 7 ］, and clock dial ［ 6 ］, monthly calendar display screen ［ 2 ］, calendar display screen ［ 3 ］ is gone through display screen ［ 4 ］ verifying unit ［ 5 ］ week and is adopted microprocessor to carry out the digital display circuit that the intelligent date handles and constitutes.The transducer ［ 10 ］ that the digital display circuit constitutes with 8363 or 8365 timing circuits ［ 12 ］ and counter-decoder circuit ［ 11 ］ and driving circuit, time base circuit ［ 13 ］ with the 60HZ oscillator as reference signal; The digital display circuit also can adopt single-chip microcomputer and address latch, and program storage forms computer system, and its signal transmits by serial port, by 4094 and line output, and the driving LED display screen.The display screen of digital display monthly calendar, calendar, Zhou Li all adopts LED.This calendar timing clock adopts numeral and simulation dual mode to constitute the complete time: the moon, day, week, the time, minute, second.And can handle automatically and adjust leap year and big solar month of 30 days.

The digital display circuit key of this calendar timing clock is: time base circuit ［ 13 ］ adopts 5369 circuit, constitute the 60HZ oscillator with crystal oscillator etc., send into 8363 or 8365 timing circuits ［ 12 ］ as reference signal, 8363 or 8365 timing circuits ［ 13 ］ carry out frequency division to 60HZ signal etc., decoding, output month, day field signal and the morning, afternoon signal and 1HZ signal second, transducer ［ 10 ］ by counter-decoder circuit ［ 11 ］ and driving circuit formation, direct driven for emitting lights diode (OLED) display screen demonstrates the time state of month, day.The morning, signal became high level by low level in the time of 24, makes counting circuit CD4158 week go through counting, and binary-coded decimal is delivered to code translator CD4511, passed through transducer ［ 10 ］ driving again and week went through display screen.Whenever the CD4518 count value is 7 o'clock, export high level with counter CD4518 zero clearing with door F, and CD4511 is changed to complete bright state, make and go through display screen demonstration " day " week, to represent Sun..

220 volts of alternating currents are delivered to display screen+utmost point through transformer transformation and rectification with higher DC voltage, are the digital display circuit supply by 7806 voltage stabilizings.Simultaneously, also rechargeable battery E is lied prostrate and fill charging.In case AC outage, by commutation circuit, E takes over power supply immediately, guarantees normal operation circuit.Supply voltage is through D ₃The crystal clock power supply is supplied with in voltage stabilizing, makes its operation.

The also available Single-chip Controlling of this calendar timing clock digital display circuit as with MCS-51 or HC05 single-chip microcomputer, connects IC ₂Address latch, the IC1 program storage forms computer system, by serial port RXD, TXD to IC ₅～IC ₉Serial output information is by P ₃After line allows, IC ₅～IC ₉4094 and line output, the driving LED display screen.At single-chip microcomputer IC ₃Be added with buffer circuit IC between serial port and 4094 circuit ₄On the digital display circuit, also do not have year calendar, monthly calendar, calendar, week to go through initial verifying unit, and striking mechanism is housed on the single-chip microcomputer.In addition, by the single-chip microcomputer output signal, through bridge drive circuit, drive stepping motor drives the clock and watch train and makes simulated clock and calendar digital display synchronous.

This calendar timing clock novel structure is fit to the use-pattern of people's custom, can be directly perceived, clear, indicate the complete time exactly, and can adjust profit year and big solar month of 30 days automatically, and be family, very good novel timing tool in office and the various public place.
