Present invention is described with regard to an embodiment with reference to the accompanying drawings.
Fig. 1 is the block scheme of an expression exemplary functions structure of the present invention, a complex data memory storage 120, for example, the ROM(ROM (read-only memory)), wherein give and having write earlier giving the earliest first day in fixed number every year in purpose time (being referred to as " the earliest first day " later on), originate in a month piece of data (below be referred to as " first lunar month ") of this lunar calendar of first day, originate in one month of last lunar calendar of first day the sky logarithmic data (below be referred to as " fate of last lunar month of last one year ") of last one year, the leap month information of this month (below be referred to as " the last leap month data of last one year "), originate in the fate (hereinafter referred to as " fate of lunar month ") of each first day lunar calendar each month in certain year, with and the leap month information (below be referred to as " leap month data ").
Switchgear 111 is controlled by an external switch 121, in order to determine still to calculate lunar calendar and ROKUYO by any established data according to calculating lunar calendar and ROKUYO by 101 determined present days of time set.
To be described at such a case below, calculate lunar calendar and ROKUYO according to the data that are stored in the data storage device 102 by switchgear 111.
According to the data in 1 year that are stored in the data storage device 102, canned data conversion equipment 119 by complex data memory storage 120 will be the earliest first day data and first lunar month data be transferred to day access to storage device 104, fate and the fate of first lunar month in this year of last lunar month of last one year are transferred to fate memory storage 105, and the data with last one year last leap month the and the leap month data in this year information-storing device 106 deliver to the leap month.
With 1984 be example, Fig. 2 show first day the relative lunar calendar of data the moon and day and every month fate, and show the situation that is stored in after these data are handled in the complex data memory storage 120.Because the fate by the lunar month that is drawn in the data processed only has only 30 days or 29 days two kinds of situations.Therefore, with 1 sky logarithmic data that just is enough to represent each lunar month, be about to conduct " 1 " in 30 days and conduct " 0 " in 29 days.Equally, if will with the leap month when irrelevant a lunar month the leap month information as " 1 ", and with the leap month relevant lunar month the leap month information as " 0 ", the leap month information of each lunar month also is enough to use 1 bit representation so.Therefore, compare with the situation of directly fate all being stored, the storage volume of the complex data memory storage 120 that the present invention is used requires much smaller.
When canned data conversion equipment 119, data are sent to day access to storage device 104, fate memory storage 105, the leap month information-storing device 106 after, content in these devices is shown in Fig. 3 (a) respectively, Fig. 3 (b), Fig. 3 (c) (with data instance in 1984).With first day of January in this year as " 1 ", according to first day data the earliest in the day access to storage device 104 and the sky logarithmic data in the fate memory storage 105, calculate accumulation day by first an accumulation day calculation element 107, and with the result of calculation sequential storage in the first accumulation day memory storage 108, respectively use Ti(i=0 below the resulting data this moment, 1,2 ...) expression.Fig. 4 is an operational instances process flow diagram in this case.
At first, the fates in this year are stored among the register DT in 401 steps, then, 402 steps will be the earliest deposited register T in first day, in 403 steps, with counter C zero setting.This first three step is carried out the initialization to this process.
After the initialization,, made comparisons in the count value of counter C and " 1 ", further compare with " 0 " in the count value of 405 step counter C in 404 steps.When the count value among the counter C equals " 0 ", check b
0Whether the position places " 1 ", if "Yes" deposits data register D in 30, if "No" then deposits data register D in 29.Then, in 409 steps, from the value of register T, deduct the value of register D, and deposit the result in register TD.In 405 steps, if the count value of counter C is not equal to " 0 ", in other words, Counter Value equals 1, so with register D zero setting, and with the value of register D and the value addition of register T, and deposits the result in register T.In 415 steps, deposit the content of register T in register TD.
In 404 steps,, check b(c-1 so if the count value of counter C neither is 0 also to be not equal to 1) whether the position is 1, if "Yes" deposits register D in 30, if "No" then deposits register D in 29.With the value of the value of register D and register T mutually adduction deposit the result in register T, then, the content of the register T register TD that restores.
In 416 steps, the content of register TD is deposited into the address C of the first accumulation day register with data Tc.In 417 steps, the value of register TD and the value of register DT are compared, if the value of register TD is greater than the value of register DT, the count value of counter C is subtracted 1 and deposit the result in register CN, if the values at 417 step TD are not more than the value of DT, the count value of counter C adds 1 so, and gets back to for the 404th step, so repeat, up to the value of register TD value greater than register DT.
Then, according in the day access to storage device 104 the 1st lunar month data and the leap month leap month data in the information-storing device 106, calculate the data of each month that originates in each lunar calendar of first day by lunation calculation element 109, and with its sequential storage in lunation memory storage 110.In the case, use KMi(i=0 respectively, 1,2 below the resulting data ...) expression, Fig. 5 is a process flow diagram of representing an operational instances in the case.
At first, counter C is put 0 in 501 steps, 502 steps with first lunar month data send into register KM, thereby to program initialization.In 503 steps, check whether the count value of counter C equals 0, if "Yes" deducts b with the value of register KM
1' and with the result register KM that restores, if "No" adds b with the value of register KM
1', its result deposits register KM in, and the value of register KM is with numerical value KM
CForm deposits the address C of lunar month storer in.Then, check whether the count value of counter C equals the value of register CN, if "Yes", EOP (end of program).If "No" counter C adds 1, program flow returns to 503 step, so repeat, equal the value of register CN up to the value of counter C.
Every change 1 year, above process is only carried out once.The first accumulation day memory storage and lunar month memory storage content be shown in Fig. 6, each data is to be that example is resulting with 1984.
The second accumulation day calculation element 112, as " 1 ", calculate accumulation day with first day of January in this year by the selected date of switchgear 111 (year, month and day), result of calculation is stored in the second accumulation day memory storage 113, this moment accumulation day be referred to as GD.
Comparison means 114 will be stored in comparing with GD successively accumulation day in the first accumulation day memory storage 107, and when greater than GD, comparison means 114 produces a signal.Lunar calendar calculation element 115 receives the output result of comparison means 114, and through calculating the moon and the day that has promptly obtained lunar calendar, the lunar calendar that calculates is stored in the lunar calendar memory storage 116.

Fig. 7 is an operational flowchart, expression comparison means 114, and lunar calendar calculation element 115, lunar calendar memory storage 116, ROKUYO calculation element 117 and ROKUYO memory storage 118 obtain the operational flowchart of foregoing lunar calendar and ROKUYO.
At first, 701 steps to counter C zero clearing, in 702 steps, the count value of counter C adds 1, then, whether the value of checking register GD less than Tc, if "No" went back to for 702 steps, is "Yes" up to its result, if "Yes" deducts T with the value of register GD
C-1, adding 1 again, the result of gained deposits register KD, KM in
C-1Be stored in register KM, the value of register KD and KM is stored in the lunar calendar memory storage.With the value of register KM and the value addition of register RD, addition result is removed by 6, and resulting remainder deposits in the ROKUYO memory storage.
Illustrate the calculating of lunar calendar and ROKUYO below in conjunction with real data.For example, calculate the lunar calendar and the ROKUYO in November 27 1984 Christian era.
By the second accumulation day calculation element 112, the accumulation day data GD that can draw November 27 is " 332 days ", it is stored in the second accumulation day memory storage 113, comparison means is seriatim to GD data and the accumulation day data Tc(c=1,2,3 that is stored in the first accumulation day memory storage 108 ...) compare, as shown in table 1, its operating process as shown in Figure 7.
Therefore, be exactly the October 5 of lunar calendar the 27 days November in 1984 of solar calendar, because R=3, so ROKUYO is " Tomobiki ".Further, because with resulting lunar month data KM
12Information b ' the leap month of corresponding
12Be 0, therefore, expression lunar calendar October is intercalation October.
If be used to calculate the earliest first day that the date of the solar calendar of lunar calendar has precedence over this year that will calculate, so just need know last one year last lunar month and day number and the leap month information.
According to the present invention, can obtain lunar calendar and ROKUYO very simply corresponding to the solar calendar date.
When having changed the date, after determining then, just can calculate each accumulation day of first day in this year by the external data changeable device.Then, by the same operation that obtains lunar calendar, can obtain the accumulation day in different months, this accumulation day compares with each accumulation day of first day, as the latter during greater than the former, from GD, deduct that first day the accumulation day before accumulation day of first day being compared and add " 1 ", thereby can determine the date of lunar calendar, after the time is determined, also can determine the month of lunar calendar, therefore, be exactly the data in a month of lunar calendar with first day data of corresponding lunar month of accumulation day.When the time does not change, can calculate its lunar calendar very soon.
