Description
Technical field
The utility model relates to a kind of electronic information input system of automated machine, a kind of electrical abacus comprehensive function system.
Background technology
The world today be robot calculator development and use golden age, yet the ancient abacus of traditional type, especially in China; Remain the handy computational tool of staff's (main ratio be financial and accountancy personnel) of a large amount of numerous and diverse data of daily processing, though advanced electronic calculator has the arithmetic speed of per second hundreds of millions times, in fact it awaits the prior input of raw data; Receive at the same time and need carry out fixing approximately of the total one group of raw data that adds up to; Consummate professional typing personnel also all do not import computing machine with data, and the accountant of corresponding professional grade has reported the result come out with abacus with it, daily data processing; It more is plus and minus calculation; For widely current conventional key board input type electronic calculating tool, to analyze relatively, abacus has its unique advantage really:
1, abacus divides the position with shelves, and is visual in image, has only five pearls (with respect to five buttons of computing machine) on the shelves, and combination is simple, whenever dials in a definite numeral, in 10 numeric keys, selects finder to simplify than computing machine;
2, the action of pointing in the human reflex activity of playing is reacted nimble agility than push action, but and thumb in the abacus computing, food, in three refer to and usefulness that and computing machine can only singly refer to press a button at synchronization.
3, abacus is operation result when dialling in data, can save the input step that computing meets (+,-,=);
4, abacus does not need the input action of zero-sum radix point in the data; Such as 1000.20, as long as " 1 " and " 2 " two actions, computing machine then needs " 1000.2+ " seven actions; Plus and minus calculation for common 2 little logarithmic datas of 3 integers; In 0 probability that on every, occurs is 1/10, the input of radix point and sign of operation in addition, and abacus on average omits 1/3 and even more input action than computing machine.
Certainly; For more senior computing, abacus is seen but import angle from data far away from electronic equipment; The above-mentioned advantage of abacus is that to be difficult to the computing machine institute of existing keyboard substituted; Read to be convenient to data though have the abacus of additional character demonstration, and abacus and the only combination on physical space of pocket calculator, substantial change does not all take place in it.
The utility model content
In order to solve existing technical matters in the background technology; The utility model provides a kind of electrical abacus comprehensive function system; The advantage that is ancient abacus of collection and modern computer is merged the electronic calculating tool of one; Be to be used for keyboard operation with the rechoning by the abacus fingering to carry out the data input, computer system is accomplished data processing and output.
The technical solution of the utility model is: a kind of electrical abacus comprehensive function system, and its special character is: the logical circuit that said system comprises the time schedule controller of keyboard switch circuit, the supervisory keyboard on-off circuit data of the keyboard unit that carries out input operation, supervisory keyboard unit, handle data and with the output unit of data output; Said keyboard unit, keyboard switch circuit, time schedule controller, logical circuit and output unit connect successively.
Said system also comprises the computing machine to the data calculation process, is connected through interface circuit between said computing machine and the output unit.
Said system also comprises display unit, and said display unit is connected with computing machine.
Above-mentioned keyboard unit is group pearl keyboard of abacus type stepping layout.
Above-mentioned keyboard unit is to be regarded as (everybody is 0) under the liquidation state, to subtract each other the rechoning by the abacus fingering operation that (negative input) is regarded as under the dishful state (everybody is 9) with addition (positive number input).
The bits per inch word that above-mentioned keyboard switch circuit produces the input data comprise with it weigh accordingly, the signal of value and symbol (or addition additive operation).
The system of the utility model can replace existing computer keyboard input media or compatible with it; After calculating, result of calculation is shown on the display screen of counter intuitively; The mode of operation of abacus type and the computing function of electronic calculator are combined; The data input is carried out in the pearl keyboard operation of dialling that is used for special construction with the rechoning by the abacus fingering, accomplishes operation of data, handles and export to show.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 .1-Fig. 2 .5 is the specific embodiment synoptic diagram of the utility model;
Embodiment
Referring to Fig. 1; The electrical abacus comprehensive function system of the utility model; The logical circuit 4 that comprises the time schedule controller 3 of keyboard switch circuit 2, supervisory keyboard on-off circuit 2 data of the keyboard unit 1 that carries out input operation, supervisory keyboard unit, data are handled, with the output unit 5 of data output, to the computing machine 6 and the display unit 7 of data calculation process; Keyboard unit 1, keyboard switch circuit 2, time schedule controller 3, logical circuit 4 and output unit 5 connect successively; Be connected through interface circuit 50 between computing machine 6 and the output unit 5, display unit 7 is connected with computing machine 6.Keyboard unit 1 is group pearl keyboard of abacus type stepping layout.Keyboard unit 1 is to be regarded as (everybody is 0) under the liquidation state, to subtract each other the rechoning by the abacus fingering operation that (negative input) is regarded as under the dishful state (everybody is 9) with addition (positive number input).
The bits per inch word that 2 pairs of keyboard switch circuits dialling pearl control are transfused to data produce comprise with it simultaneously weigh accordingly, the signal of value and symbol (or addition additive operation), by 3 controls of time schedule controller, handle through logical circuit 4; With dial the corresponding circuit port output data of pearl gear; Carry out calculation process and output demonstration after interface circuit 50 connects computing machine 6, thus, native system also is a kind of digital display box simultaneously; In the time of as input, show word.
Referring to Fig. 2 .1-Fig. 2 .5, the embodiment of the electrical abacus comprehensive function system of the utility model is following:
1) USB is attached to main frame, also can use wirelessly, and online is a kind of device;
2) upper ledge is digital display box, representes the district for abacus down, and for example: input 1234 also changes along with the variation of abacus pearl with regard to the number numeral;
3) black block 10 is the digital display range district; As following, still show 1234 (the rechoning by the abacus pearl 75 of back, not operations);
4) if black block 10 is moved to right, then be 12340075;
5) left side can add Button, numerical value is dished out (can set, directly dish out, or button is dished out)
