Abstract

The utility model relates to a full automatic permanent calendar which can be used for automatically looking up the day of a week of some day, the date of the day in lunar calendar, great lunar festivals of some year and 24 solar terms of the year and judging the intercalary month. In addition, the permanent calendar has the function of time and calendar display. The utility model comprises an electrical source, a single chip microprocessor, a memorizer, an interface circuit, a keyboard and a displayer. Because the large-scale integrated circuit is used, the utility model has the advantage of small size and is suitable for assembling into articles in various shapes, such as a desktop, a wall type, etc. With the further development of microelectronics, the utility model can make the low cost and the miniaturization realized.

Description

Look-up type computer permanent calender

The utility model is that a kind of full-automatic a century is gone through, and specifically, is to have the computer a century that can inquire about multinomial content automatically in 100 years to go through.

In the daily life, year calendar is essential.But because calendar calculates, particularly the lunar calendar calculates very complicated.Therefore be difficult to make the year calendar calculation automation.Existing perpetual calendar on the market, monthly calendar all can only adopt manual inquiry mode, and is extremely inconvenient.Though this is domesticly had nearly hundred relevant patented claims.But wherein exhausted major part all is manual, needs regularly to be provided with.Adjust, a small amount of employing electronics is also arranged, the year calendar of electric device.But short when striding, can not inquire about and limited its usable range.

The purpose of this utility model provide a kind of can in 100 years, can consult automatically certain day be 1＞what day 2＞lunar calendar which date and judge whether the leap month 3＞as import certain lunar calendar day, then exportable week, the calendar year, month, day.In addition, also can consult great lunar calendar red-letter day (as the Spring Festival, the Dragon Boat Festival etc.) and 24 solar term in certain year automatically.

Technical method of the present utility model is: with every month crux data in 100 years through coding after, form tables of data and put into storer EPROM.When importing certain calendar day, program can be calculated automatically according to the year calendar computation rule, and the result is shown with digital form.The utility model comprises one-chip computer, eprom memory, interface circuit, keyboard and display circuit, parts such as power supply.

The utility model has the advantages that: 1. easy to use, only need selection function and input digit can in 100 years, demonstrate the data of desiring to consult intuitively.2. usable range is long, and centenary calendar can satisfy people's needs in all one's life substantially.After 100 years, also only need change the data among the EPROM simply.Can reuse again.

Accompanying drawing one is the utility model profile synoptic diagram.Accompanying drawing two is a circuit structure diagram of the present utility model.

According to figure one, two embodiment that provide, figure one has provided casing of the present utility model, wherein: 1. function selecting panel 2. keyboards 3. displays 4. functional status pilot lamp, the circuit diagram of figure two comprises 1. storages, processing unit 2. input/outgoing interface unit 3. digital display units, 4. keyboards and function selecting unit 5. state indicating members.In the unit 1, microprocessor 80C31 is under the clock frequency effect of external crystal, through latch 74H373 taking-up program or fixed data from storer 27C256EPROM; Unit 2 is expansion output interface circuit 82C55, and its A mouth, B mouth are respectively through driving circuit U7, and U9 drives six charactrons.The C mouth divides two the tunnel through U5, and the U6 code translator drives function corresponding indication light emitting diode.AN1 is a reset key.AN2, AN3 are function selecting key, with the INTO end that meets U1, when pressing, call interrupt service routine and carry out selection and computing function.AN4 is the date display key, connects the INT1 end of U1, when pressing, calls the date, and week shows interrupt routine.Keyboard connects the P1 mouth of U1.

The principle of work of circuit is such: at ordinary times, microprocessor 80C31 takes out timing program through address latch 74H373 in the unit one from storer 27C256EPROM, and a century is gone through and made clock timing usefulness.As want to inquire about calendar etc. for information about, by function key F1, F2 selects function corresponding after software processes earlier.The function selecting state drives D1-D8 and D9-D14 respectively by two 3-8 code translator 74HC138.These 14 light emitting diodes are placed by 6 * 8 matrixes, and its point of crossing is the function of choosing.At this moment, this functional status of program eucalyptus looses and forwards this function subprogram to.When input from keyboard year, month, day and when carrying out, program is by tabling look-up and call the relevant calculation module, relevant Query Information moment can show.According to same principle, the utility model also can change thousand year calendars into easily.

Claims

1, but a kind of query formulation computer a century is gone through, comprise casing, power supply, chip microprocessor, storer, keyboard and display, principal character of the present utility model is: except that can do clock and the same day calendar also can be showing to any certain day the Gregorian calendar in 100 years, the great lunar calendar in the lunar calendar and certain year red-letter day, 24 solar term are inquired about automatically, and can show the result is instantaneous.

2, as described in claims 1., the utlity model has multiple query function, the selection of various functions is all operated on the function selecting panel.It is characterized by by 14 light emitting diodes and form the 6X8 matrix, its point of crossing is the operating function of choosing.
