Abstract
The utility model relates to the field of mathematical calculation training, and especially relates to an abacus for abacus mental calculation training. The abacus comprises an abacus frame provided with abacus beads, a solar photovoltaic plate arranged on the abacus frame and used for providing power supply, a liquid crystal display screen used for displaying exercises, answers and time, and a switch used for turning on or turning off the device. According to the technical scheme provided by the utility model, structure is simple, technology is reasonable, energy is saved, and the abacus mental calculation training can be completed by oneself alone to understand correct rate and speed of calculating.
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 the training of abacus mental calculation to us, 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 big 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.
Summary of the invention
The utility model provides a kind of abacus can carry out the training of abacus mental calculation to oneself at 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 mental calculation training abacus, comprise the abacus frame that abacus bead is housed, also comprise the solar energy photovoltaic panel that is used for providing power supply, the LCDs that is used for showing education question, answer and time that is installed on the described abacus frame, the switch that is used for opening or closing this equipment.
As preferably, also comprise the data-carrier store 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; Provide power supply by solar energy photovoltaic panel, the central processing unit that is used for reading the education question in the data-carrier store and shows by LCDs.Be connected with switch between central processing unit and the solar energy photovoltaic panel.
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 signal and then reads education question in the data-carrier store, and shows education question by LCDs.
As preferably, described central processing unit also be used for receiving pressure transducer detect information, read the answer of education question in the data-carrier store and show by LCDs.
When the training end, 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 answer that signal then reads education question in the data-carrier store, and shows answer by LCDs.
As preferably, described central processing unit also is used for calculating detecting pressure signal from pressure transducer, to detecting less than 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, and energy savings can oneself be finished the training of abacus mental calculation alone, and understands accuracy and the speed of oneself calculating.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model principle of work block diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
A kind of abacus mental calculation training abacus, as shown in Figure 1, comprise the abacus frame 1 that abacus bead is housed, also comprise the solar energy photovoltaic panel 2 that is used for providing power supply, the LCDs 3 that is used for showing education question, answer and time that is installed on the described abacus frame, the switch 4 that is used for opening or closing this equipment.
As shown in Figure 2, also comprise for the data-carrier store 7 of storing 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; Provide power supply by solar energy photovoltaic panel, the central processing unit 5 that is used for reading the education question in the data-carrier store and shows by LCDs; Central processing unit also be used for to receive pressure transducer detect information, read the answer of education question in the data-carrier store and show by LCDs; Central processing unit also is used for calculating detecting pressure signal from pressure transducer, arrives and detects less than the time between the pressure signal, and show 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 signal and then reads education question in the data-carrier store, and by LCDs demonstration education question, train timing to begin simultaneously; 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 answer that signal then reads education question in the data-carrier store, and by LCDs demonstration answer, train timing to finish simultaneously, and show the training time by LCDs.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
