Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills obtained belongs to the scope of protection of the invention.
Embodiment one
The embodiment of the invention one at first provides a kind of counter, and this counter can comprise numerical key, student number input indication key, display and storer.
Wherein, numerical key can have 10, respectively corresponding 0 to 9 these 10 numerals.
In actual applications, need a lot of examinees' of statistics exam score usually, and can distinguish each examinee by student number usually.At this situation, the counter of the embodiment of the invention is provided with student number input indication key, and also, the user can also at first import this examinee's student number before certain student's of statistics examination score, can distinguish different examinees' score like this.Input just can at first be pressed this student number input indication key during the number of examining, and next just can press the numeral of specifying figure place, 4-digit number for example, and then counter just can indicate the 4-digit number of importing afterwards be identified as examinee's student number the student number input.Each numeral of student number correspondence can not count follow-up exam score statistic processes, only is equivalent to distinguish each different examinee with different numeral numbers.
Concrete, the student number of supposing each examinee is four, then after pressing student number input indication key, just can import 4-digit number, can press speed then and add the beginning indication key, and, press numerical key according to the score of this each little topic of examinee, press dibit input indication key when being necessary or decimal input indication key gets final product.After the exam score statistics with an examinee finishes, can press student number input indication key again, and press the numerical key of next but one examinee's student number correspondence, repeat subsequent operation then and get final product.
Certainly, examinee's student number may be tactic usually, in order further to improve the exam score statistical efficiency, next student number input indication key can also be set on counter.Like this, only need be when first examinee's of statistics examination score, need press student number input indication key, and press corresponding numerical key of each numeral of student number, after having added up first examinee's examination score, just can be by next but one student number input indication key, the computational logic of counter just can be according to preset rule, automatically on the basis of a last student number, obtain current examinee's student number, and do not press each numerical key of current examinee's student number correspondence with not needing another.For example, current examinee's student number is always gone up a student number and is added one, when then receiving next student number input indication, just a last student number can be added one, gets final product as current examinee's student number.
When storage examinee's exam score, can preserve the student number of each exam score correspondence.Wherein, the exam score here can comprise examinee's examination total points, also is, input according to the user, can calculate each examinee's examination total points, and preserve examinee's student number and the corresponding relation between the examination total points, can learn it specifically is how many which student examinations always got like this.In addition, in some applications, may need to add up the score situation of each each little topic of examinee, therefore, when storing final examination total points, can also store the score of each little topic respectively, also be, when preserving the corresponding relation between student number and the exam score, this exam score also can be meant the corresponding relation between each little topic score of preserving student number and this examinee.Certainly, store at needs under the situation of score of each little topic, at each little topic, even certain this little topic of examinee must be divided into 0, when the statistics exam score, also need on counter, press " 0 " corresponding numerical key.Correctness with the corresponding relation between the topic that guarantees each little topic number and the score.
In the preferred embodiment of the present invention,, can also adopt the mode of " speed adds " to calculate in order further to improve the computing velocity of exam score.Also promptly, counter can have speed and add pattern, under this pattern, calculates with special computational logic.Wherein, embodiment of the invention what is called " speed adds " is for common additive operation, for common additive operation, need repeatedly press "+" key, and the method for the embodiment of the invention does not need to press "+" key when carrying out additive operation, can save user's touch potential, velocity ratio is very fast, therefore, is called " speed adds ".In this case, this counter can also have speed and adds beginning indication key and speed and add the end indication key.
Certainly, this counter also can be used for common additive operation, therefore, in order to distinguish mutually with common additive operation, this counter has speed and adds the beginning indication key, and when the user pressed this key, counter just can be handled user's input according to the logic of " speed adds ".For the user, after pressing this key, just can import the score of each little topic in proper order, during do not need to import adding operator; After the score of having imported each little topic, can also press speed and add the end indication key, counter just can think that the user has finished the input of each little topic mark after receiving this indication, then, the output of the addition result of each little topic score is got final product.Certainly, this counter can have display, can demonstrate the numeral of user's input, and final exam score output result.
Simultaneously, owing to need to calculate several examinees' exam score usually, therefore, the embodiment of the invention can also temporarily be stored in the current examinee's that calculates exam score in the counter, and then calculate next examinee's exam score, from counter, read out each examinee's exam score at last again.Therefore, this counter also has storer, is used for the exam score that storage computation goes out.
Need to prove, in the process of the counter statistics exam score that utilizes the embodiment of the invention to provide, if adopt speed to add pattern, then the user does not need the inputting mathematical sign of operation, and only need import the score of each little topic, counter just can provide the exam score that finally calculates, and below this is at length introduced.
Wherein, for exam score, at first have following characteristics: the score of each little topic generally all in 10 minutes, therefore, in embodiments of the present invention, is being carried out the speed added-time, and the user only need press numerical key successively and get final product.For example, suppose to have five little topics, from first little the 5th little topic of inscribing, certain examinee's score is respectively 3,5,2,7,6, and then the user directly imports " 35276 " and gets final product.Accordingly, because the user is continuously the mark of each little topic of input, the centre does not have conduct intervals such as sign of operation, for common computing machine, " 35276 " can be treated as a five-digit number, but in fact should is five one digit numbers.Therefore, can correctly calculate and provide result of calculation, also need the computational logic of counter is made amendment in order to make counter.
Concrete, can set in advance the separation condition, make that under speed adds pattern computational logic can be separated the character of user's input according to this separation condition.For example, the most basic separation condition just can be: when the character of the continuous input of user all is numeral, separates between the bits per inch word, and the bits per inch word is defined as the score of each little topic.That is to say, in previous example, when user's input " 35276 ", utilize this separation condition, just this a string character can be divided into 3,5,2,7,6 these five one digit numbers, and these numerals are carried out additive operation, and finally import addition result: 23.
Certainly, in some cases, the score that also may have certain little topic is double-digit situation, for this reason, can also have dibit input indication key on the counter that the embodiment of the invention provides, for example, can be shown as " S " on the key, when the user imports certain double figures at needs, just can at first press this dibit input indication key, and then press the numerical key of this double figures correspondence respectively.For example, certain little topic score is 12 minutes, then can press dibit input indication key earlier, and then press " 1 ", " 2 " two numerical keys respectively, and computational logic just can be treated " 12 " as a double figures like this.
Perhaps, in other cases, the score that also may have certain little topic is the situation of decimal, and the numeral behind the radix point generally all is 5, and for example, the score of certain little topic may be 1.5, perhaps 2.5, or the like.For this reason, in the counter that the embodiment of the invention provides, can also have decimal input indication key.Concrete, when certain little topic must be divided into decimal the time, then can import the integral part of this decimal earlier, and then press decimal input indication key.Like this, computational logic just can be handled the score of this little topic as a decimal.For example, certain little topic score is 2.5 minutes, then can press the numerical key at " 2 " place earlier, only need press decimal input indication key then, and computational logic just can be with 2.5 scores as current little topic.Certainly, if the numeral of decimal place all is not 5, then also can be set to other numeral, perhaps, also can allow the user to import complete decimal, also promptly can be as normal decimal input, after having imported integer-bit, import decimal input indication again, and then input decimal place numeral.Certainly, for the latter, all right corresponding modification computational logic makes that computational logic can be the score of next little topic with the next digit recognition after the decimal place.
Need to prove, in actual applications, may use one or more in the above-mentioned various separation condition, and can't conflict mutually between each separation condition.For example, a string character of user's input is: 245S12476.258, then the computational logic of counter can be identified as it: 2,4,5,12,4,7,6.5,2,5,8 these ten numbers.If the user has imported speed and adds and finish indication afterwards, then can provide exam score: 55.5.
In actual applications, some teaching tools may also need the mark of each student's exam score or each little topic is carried out some statistics, to analyze the grasp situation of student to each knowledge point, or the like, like this, may need examinee's the exam score or the score of each little topic are input in the computer system.For this reason, can also comprise data transmission interface on this computing machine, the data of storing in the counter can be exported in the computer system by this interface.Like this, just can carry out various statistical study in computer system has operated.Wherein, this data transmission interface can be common USB interface or the like, and, for the ease of being connected with more hardware product simultaneously, can also have a plurality of USB interface simultaneously.As seen, the counter that utilizes the embodiment of the invention to provide can also help to realize mark typing fast, helps the realization of Assisted Instruction Software function.
Certainly, can also comprise some function keys on this counter, for example individual event clear key and erase all key etc., wherein, the individual event clear key is used to remove last character of current input, and erase all key is used to remove all characters of current input.
In addition, do not carrying out under the situation of fractional statistics, this counter can also use as common counter, perhaps, can link to each other with portable computer etc., and as the numeric keypad of expanding, or the like.For this reason, can also have the switching indication key on this counter,, counter be switched to the pattern of various needs by this switch key.
For example, shown in Figure 1 just can be a kind of counter that the embodiment of the invention provides, wherein, has 0 to 9 10 numeric keys, what " 00 " was corresponding is dibit input indication key, what ". " was corresponding is decimal input indication key, what " Num Lock " was corresponding is student number input indication key, what "/" was corresponding is next student number input indication key, what " * " was corresponding is that speed adds the beginning indication key, and what " Enter " was corresponding is that speed adds the end indication key, and what "-" was corresponding is erase all key, what " Back Space " was corresponding is the individual event clear key, and what " switching " was corresponding is to switch indication key.What "+" was corresponding is add key, when the user switches to common calculator mode with counter, should "+" can be used as add key use in the common counter, be that the user can be after each little topic mark of input, input "+", like this, the computational logic of counter can be automatically with its separator as each little topic score, and execution simultaneously, can also be write down the score of each little topic with the operation of the mark addition of each little topic.
