Abstract
The utility model relates to the mathematics calculation training field, and especially relates to an abacus for abacus mental calculation training; the abacus comprises a left abacus frame and a right abacus both provided with abacus beads; the left abacus frame is connected with the right abacus frame through a connecting shaft; the left abacus frame is provided with a blank plate for recording; the right abacus frame is provided with a liquid crystal display for displaying training topics, answers and the time; and the right abacus frame is also provided with a switch for opening or closing the equipment. The abacus employing the technical scheme is simple in structure, reasonable in technology, enables a person to independently finish abacus mental calculation training, and enables the person to learn about calculation correct rate and speed; training time can be recorded on the blank plate and compared with previous times; and the abacus is more conveniently to carry through a folding mode.
Description
Technical field
The utility model relates to mathematical computations training field, relates in particular to a kind of abacus for abacus mental calculation training.
Background technology
Remember that as a child every day, teacher can carry out to us the training of abacus mental calculation, from incipient 1+2+3+......+100, rechoning by the abacus double figures addition is finally multiplied each other, and three figure place additions are multiplied each other, and arrive last mental arithmetic etc. again.The accuracy rate that these training not only will be trained us, the speed that also will train us.This training can be developed child's intelligence well, and is very large to child's growth benefit.But this training must have teacher or other people on the scene, provides exercise question by them, and judges the correct or mistake of answer, and calculates time of answer by stopwatch, to such an extent as to we can not carry out abacus mental calculation training to ourselves.In addition, abacus mental calculation is a training that not to advance is to go back, so children often, can go home training for a moment with abacus, but because the length of abacus can not be put school bag into, take inconvenience very, put school bag into and can not zip up again, the thing in the school bag is easy to drop.
Summary of the invention
The utility model provides a kind of abacus can carry out to oneself the training of abacus mental calculation for deficiency of the prior art, detects the accuracy of oneself and the speed of answer.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of abacus, comprise left abacus frame and right abacus frame that abacus bead is housed, described left abacus frame links to each other with right abacus frame by coupling shaft, described left abacus frame is provided with the blank plate for record, described right abacus frame is provided with for the LCDs that shows education question, answer and time, also is provided with on the right abacus frame for the switch of opening or closing this equipment.Its left abacus frame and right abacus frame can fold, and can put abacus into school bag easily.
As preferably, also comprise be used to the power supply that voltage is provided; The data-carrier store that is used for storage education question and answer; Be installed in abacus bead and abacus frame contact position, the pressure transducer that whether is using for detection of abacus; The central processing unit that is used for the education question in the reading out data storer and shows by LCDs is provided with switch between central processing unit and the power supply.
Wherein when when beginning training, pressure transducer detects the pressure that abacus bead contact abacus frame produces, and pressure transducer sends signal, and central processing unit receives the then education question in the reading out data storer of signal, and shows education question by LCDs.
As preferably, described central processing unit also is used for receiving pressure transducer and detects to get information, the answer of education question and show by LCDs in the reading out data storer.
When training finishes, pressure transducer can not detect the pressure that abacus bead contact abacus frame produces, and pressure transducer sends signal, and central processing unit receives the then answer of education question in the reading out data storer of signal, and shows answer by LCDs.
As preferably, described central processing unit also is used for calculating detecting pressure signal from pressure transducer, to can't detect the time between the pressure signal, and shows by LCDs.
Wherein when the training beginning, pressure transducer detects the pressure that abacus bead contact abacus frame produces, pressure transducer sends signal, central processing unit receives the signal timing to begin, when the training end, pressure transducer can not detect the pressure that abacus bead contact abacus frame produces, and pressure transducer sends signal, central processing unit receives then timing end of signal, and shows the training time by LCDs.
According to the technical solution of the utility model, simple in structure, technology is reasonable, can oneself finish alone the training of abacus mental calculation, and understands accuracy and the speed of oneself calculating, in addition, and by folding mode, more convenient carrying.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of abacus, as depicted in figs. 1 and 2, comprise left abacus frame 1 and right abacus frame 8 that abacus bead is housed, described left abacus frame 1 links to each other with right abacus frame 8 by coupling shaft 9, described left abacus frame 1 is provided with the blank plate 2 for record, described right abacus frame 8 is provided with for the LCDs 3 that shows education question, answer and time, also is provided with on the right abacus frame 8 for the switch 4 of opening or closing this equipment.
As shown in Figure 3, also comprise be used to the power supply 10 that voltage is provided; The data-carrier store 7 that is used for storage education question and answer; Be installed in abacus bead and abacus frame contact position, the pressure transducer 6 that whether is using for detection of abacus; The central processing unit 5 that is used for the education question in the reading out data storer 7 and shows by LCDs 3 is provided with switch 4 between central processing unit 5 and the power supply 10.
Central processing unit also be used for to receive pressure transducer and detects to get information, the answer of education question and show by LCDs in the reading out data storer; Central processing unit also be used for to calculate and detects pressure signal from pressure transducer, to can't detect the time between the pressure signal, and shows by LCDs.
Wherein when the training beginning, pressure transducer detects the pressure that abacus bead contact abacus frame produces, and pressure transducer sends signal, and central processing unit receives the then education question in the reading out data storer of signal, and by LCDs demonstration education question, train simultaneously timing to begin; When training finishes, pressure transducer can not detect the pressure that abacus bead contact abacus frame produces, pressure transducer sends signal, central processing unit receives the then answer of education question in the reading out data storer of signal, and by LCDs demonstration answer, train simultaneously timing to finish, and show the training time by LCDs.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
