Description
Technical field
The utility model relates to a kind of educational aid, particularly relates to a kind of for proofreading the electrical abacus of abacus mental calculation bead presentation.
Background technology
Abacus type mental arithmetic, is called for short abacus mental calculation.It,, improving the aspects such as arithmetic speed, tap intellectual resources and the development of promotion nonintellectual factor, has great potential.According to the statistics of Chinese rechoning by the abacus mental arithmetic association, from the eighties in last century, in June, 2010 only, the whole world has 46 countries and regions carries out the education of abacus type mental arithmetic, wherein China has 4,200,000 people to learn abacus type mental arithmetic.Therefore carry out calculation reason algorithm research and the reform to mental abacus calculation teaching tool, learning aid and the innovation of abacus mental calculation, improve learner's abacus mental calculation computing level, can not only produce good social benefit, can produce good economic benefit simultaneously.
People generally learn abacus mental calculation technology with abacus at present.On skilled basis of grasping technique of bead calculation, by simulation, dial pearl or pearl is dialled in thinking, in brain, calculate on an abacus.Owing to transitting to abacus mental calculation from calculating on an abacus, natural, vivid, thus easily study and grasp of abacus mental calculation, and liked by people.But have problems, be, when each group of pearl, will imagine the position that bead motion and bead arrive, this has restricted the arithmetic speed of abacus mental calculation to a great extent.If can remove the thinking of every single stepping to bead motion in abacus mental calculation calculating process, but directly present the bead Global rehearsal that every single stepping forms, the arithmetic speed of abacus mental calculation just can improve greatly.
In the process of abacus mental calculation study and training, check and correction bead presentation, i.e. the bead presentation that check and correction " number is translated pearl " presents; Or whether the check and correction bead Global rehearsal that every single stepping forms in abacus mental calculation is calculated is consistent with actual rechoning by the abacus disc type, this is to check student whether to form the indispensable important step of clear, accurate bead presentation in abacus mental calculation study.In the past, whether the bead presentation in student's brain was accurate, and teacher can only help school pair with the card of making in advance.Proofread in this way bead presentation and not only require great effort but also costly, but also want other people to help to show card.Can be without card, student oneself can proofread the bead presentation of " number is translated pearl "; Oneself can proofread at any time the bead Global rehearsal in abacus mental calculation is calculated.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of for proofreading the electrical abacus of abacus mental calculation bead presentation, can in the situation that not using card, oneself proofread bead presentation.
The utility model solves the technical scheme that its technical matters adopts: provide a kind of and comprise processor circuit and key circuit for proofreading the electrical abacus of abacus mental calculation bead presentation, described key circuit is connected with the input end of processor circuit; Described key circuit comprises five row's bead buttons and note site, and each row of described five row's bead buttons are corresponding one by one, and wherein, row's bead button is positioned at the top in note site, and four row's bead buttons are positioned at the below in note site; Each bead button in described five row's bead buttons corresponding light emitting diode of connecting; Described bead button can change the state of light emitting diode after pressing; All light emitting diodes are connected with power end by jewel display button.
When the light emitting diode corresponding to bead button of top, described note site is open mode, each light emitting diode represents " 5 "; When the light emitting diode corresponding to bead button of below, described note site is open mode, each light emitting diode represents " 1 ".
The reset terminal of described processor circuit is also connected with reset circuit.
Described reset circuit comprises electric capacity, resistance and reset key; One end of described electric capacity is connected with the reset terminal of processor circuit, other end ground connection, and described electric capacity two ends are parallel with resistance and the reset key of mutual series connection.
Described processor circuit is realized by AT89C51 chip, between the XTAL1 port of described AT89C51 chip and XTAL2 port, is connected with crystal oscillator, and one end of described crystal oscillator is by a capacity earth, and the other end is by another capacity earth; The output terminal of described key circuit is connected with the I/O end of AT89C51 chip.
The bead button of below, described note site is pressed, and when the light emitting diode that this bead button is corresponding changes open mode into by closed condition, be positioned at the top of this bead button column and remembering that light emitting diode corresponding to bead button below site becomes open mode.
The bead button of described note site below is pressed, and light emitting diode corresponding to this bead button be while changing closed condition into by open mode, and light emitting diode corresponding to bead button that is positioned at the below of this bead button column becomes closed condition.
Beneficial effect
Owing to having adopted above-mentioned technical scheme, the utility model compared with prior art, has following advantage and good effect:
The utility model represents bead with bead button, clicks certain bead button, can change the state of bead, then clicks this bead button, can recover original state.In addition, this electrical abacus, when pressing certain bead key and make bead state variation, also has the function that drives some other bead state variation.The jewel state of bead can show or be closed by jewel display button, so can several steps in interval, proofread one time bead Global rehearsal, and in do not use in the situation of card can oneself check and correction bead presentation.
The utility model will be dialled pearl and change over by pearl, operation is simpler than dialling pearl, computing velocity is faster than dialling pearl, by pearl computing, there is not floating pearl and band pearl, therefore improved the accuracy of computing, also easily grasped the computing by pearl " touch system ", by the simulation of abacus mental calculation dial pearl or thinking dial simulation that pearl is modified into abacus mental calculation by pearl or thinking by pearl, finally form the bead presentation overlapping operation technology of abacus mental calculation, this operative technique comes from rechoning by the abacus but higher than rechoning by the abacus.Adopt this abacus mental calculation, in computing, only present jewel presentation, need not remember frame, beam, the shelves of dark pearl presentation and abacus, therefore can play simplification presentation, reduce the effect of memory.
With the utility model, when by pearl computing, accomplished that bead does not move.It can not only count and computing as calculating on an abacus, and in abacus mental calculation study, clicks bead key and can also proofread the bead Global rehearsal that this single stepping presents instantly.After skilled, reality be can break away from by pearl operation, the synchronous operation of bead presentation and the overlapping operation of bead presentation further trained.So, to grasp after these bead presentation operations, the speed of abacus mental calculation and accuracy rate will be significantly improved.
The utility model can be proofreaded the bead presentation of " number is translated pearl " voluntarily, can also proofread voluntarily the bead Global rehearsal of any single stepping in calculating, and laborsaving province wealth, can proofread rapidly bead presentation, can proofread at any time by the result of calculation of pearl touch system.
